Defining and Building Projects
The following exercises guide you through defining and building imagery, terrain, and vector projects, using the resources you created in the previous lesson.
Define an Imagery Project
If you intend to use your own imagery data, it makes sense to define and build the imagery project before adding vector data. That way, you can use the imagery project as the base image map in the Preview pane in Google Earth Enterprise Fusion when you develop your vector project, making it easier to visualize how your vector data will appear over your actual imagery.
Add Resources to an Imagery Project
Although you can change the display order of imagery and terrain resources within a project, the order is ultimately determined by the resolution of the source files. That is, lower-resolution insets are automatically ordered below higher-resolution insets. So in reality, you can change the order of resources with the same resolution only.
The following example shows a number of imagery resources in a project ordered by resolution. The resolution of each resource appears in parentheses after the resource name.
The order in which the imagery or terrain resource data appears in the Imagery and Terrain Project Editors is the same as the stacking order of the insets in Google Earth EC. That is, higher-resolution insets appear above lower-resolution insets, so that viewing preference is given to the higher-quality imagery. The stacking order of same-resolution insets follows the order you define in the project. The following graphic illustrates this concept.
To add resources to an imagery project:
- Select Asset Manager from the Tools menu. The Asset Manager appears.
- Click on the toolbar. The Imagery Project Editor appears.
- Click . The Open dialog appears.
- Navigate to the
ASSET_ROOT/Resources/Imagery
folder. - Select BlueMarble, and click Open. The BlueMarble resource appears in the Imagery Project Editor.
- Repeat steps 4 through 6 for each of the following resources:
- SFBayAreaLanSat
- i3_15Meter
- SFHighResInset
The resources appear in order by resolution, with the higher resolution imagery at the top of the list.
ASSET_ROOT/Projects/Imagery
folder.Build an Imagery Project
As with resources, you do not have to build projects right away. You can define several projects and then build them all, or you can wait until you include them in a database and build the entire data hierarchy at the same time. However, in this lesson, you build the imagery project right away, so you can use it as a base map in the Preview pane.
Note: It could take up to 10 minutes for the project to build. Do this exercise when you can spend some time away from your computer while the project builds.
- In the Asset Manager, navigate to ASSET_ROOT/Projects/Imagery in the asset navigation tree.
- Right-click SFBayArea and select Build from the context menu.
The status of the project immediately changes to Queued and then In Progress. (Sometimes the status changes so rapidly that it appears to change directly to In Progress.)
As with building imagery resources, you can view the progress of the build by double-clicking the Current Version or Current State column for the project. The Version Properties dialog displays the most recent version of that project. You can expand the version tree to view the status of the build in real time by clicking the + signs.
When the status of the imagery project build is Succeeded, go on to the next exercise.
Preview an Imagery Project
You can preview an imagery project after you build it.
Note: Only bounding boxes appear in the Preview pane, not the actual imagery.
To preview an imagery project:
- Double-click the name of the imagery project you built in the last exercise, SFBayArea. The Imagery Project Editor for that project opens.
- Check the box next to Preview above the list of source files, and then switch to the main Google Earth Enterprise Fusion window.
Bounding boxes indicate the extents of each of the individual imagery resources. The largest bounding box is around the entire Earth, which is the BlueMarble imagery. (You might have to zoom out a bit to see it.) The other three bounding boxes are in the San Francisco Bay Area. You can zoom in to see them.
Note: The name of the project does not appear in the Preview List pane. When you close the Imagery Project Editor or uncheck the box next to Preview, the bounding boxes disappear. You can reset the view by pressing Ctrl-R.
Specify an Imagery Project as Your Base Map
When the imagery project build is done, you can specify it as your base map.
To specify an imagery project as your base map:
- Select Preferences from the Edit menu. The Preferences dialog appears.
- Under Background Imagery, select Imagery Project from the drop-down list.
- Click to the right of the drop-down list. The Open dialog appears.
- Navigate to
ASSET_ROOT/Projects/Imagery
, and select SFBayArea.The full path within the tutorial asset root appears to the right of the drop-down list.
- Click OK. The Preview pane displays the specified imagery. The specified imagery will remain the background imagery until you change it to another image or return it to the default imagery in the Preferences dialog.
Define a Terrain Project
The terrain project for this tutorial is very simple. It includes one of the resources you built in the previous lesson.
Add a Resource to a Terrain Project
The following procedure provides the steps to add resources to a terrain project.
To add resources to a terrain project:
- Select Asset Manager from the Tools menu. The Asset Manager appears.
- Click on the toolbar. The Terrain Project editor appears.
- Click . The Open dialog appears.
- Navigate to the
ASSET_ROOT/Resources/Terrain
folder. - Select SFTerrain, and click Open. The SFTerrain resource appears in the Terrain Project Editor.
- Check the box next to Preview.
- Right-click the name of the resource, and select Zoom to Layer from the context menu.
The Preview pane zooms in to the bounding box that indicates the extents of the terrain resource.
- Uncheck the box next to Preview.
ASSET_ROOT/Resources/Terrain
folder. ASSET_ROOT/Projects/Terrain
folder. Enter SFTerrain as the name of your project, and click Save. Build a Terrain Project
As with the imagery project, in this exercise, you build the terrain project right away.
- In the Asset Manager, right-click SF Terrain.
- Select Build from the context menu.
The status of the project immediately changes to Queued and then In Progress.
Note: It could take a while for this project to build, depending on the speed of your workstation.
When the status of the terrain project build is Succeeded, go on to the next exercise.
Define a Vector Project
The following exercises cover how to define, configure, and build a vector project using the resources you created in the previous lesson.
You spend the majority of your time in Google Earth Enterprise Fusion configuring display rules for vector projects, determining how they look in Google Earth EC. Using the data in your vector source files, you can designate specific data for a variety of display purposes, such as road labels, features lines, and icons at viewing altitudes that are most appropriate for each feature. For example:
Add Resources to a Vector Project
Before specifying the display rules for this vector project, you must add the resource you created in Defining and Building Resources.
To add resources to a vector project:
- Select Asset Manager from the Tools menu. The Asset Manager appears.
- Click on the toolbar. The Vector Project Editor appears.
- Click . The Open dialog appears.
- Navigate to the
ASSET_ROOT/Resources/Vector
folder. - Select CAHighways, and click Open. The CAHighways resource appears in the Vector Project Editor.
- Repeat steps 3 through 5 to add USPopulation to the project. Notice that a check box appears next to each resource/layer in the project.
- Check the box next to CAHighways.
- Right-click CAHighways, and select Zoom to Layer from the context menu.
The roads in the CAHighways resource appear in the Preview pane.
- Check the box next to USPopulation, switch to the Preview pane, and zoom out a bit.
Since this resource contains US census data by county, the outlines of counties across the US appear in the Preview pane as well as the roads in California.
Note: The name of the project does not appear in the Preview List pane. When you close the Vector Project Editor or uncheck the boxes next to the resources, the vector data disappears. You can reset the view, if desired, by pressing Ctrl-R.
- In the Vector Project Editor, select (highlight) USPopulation, and click to remove the US Population resource from the project. A message prompts you to confirm the deletion.
- Click OK. The USPopulation disappears.
Note: Removing the resource from the project does not delete the resource. The resource remains intact and available for use by other projects. It is just not part of this particular project.
- Select File > Save.
- Navigate to the
ASSET_ROOT/Projects/Vector
folder. - Enter CARoads as the name of your project, and click Save. The new project appears in the Asset Manager when you select ASSET_ROOT/Projects/Vector in the asset navigation tree.
Now you are ready to begin configuring the vector layer.
Configuring Layer Properties for a Vector Project
This exercise covers how to configure layer properties for your vector project. Layer properties determine a number of aspects of how your data appears and is accessed in Google Earth EC.
To configure layer properties:
- In the Asset Manager, double-click CARoads in the
/ASSET_ROOT/Projects/Vector
folder. The Vector Project Editor appears and displays the resource you added in the previous lesson. - Right-click CAHighways, and select Layer Properties from the context menu. The Layer Properties dialog appears.
- Click Off next to Initial State to change it to On. Changing the initial state to On results in the CAHighways layer being automatically checked (turned on) in Google Earth EC.
- Click the blank field next to LookAt. The Open dialog appears.
- Navigate to
/opt/google/share/tutorials/fusion/KML
, selectSan Francisco View Oblique.kmz
, and click Open.When you specify a KML/KMZ file in this field, Google Earth EC users can fly directly to the specified camera view by double-clicking the layer.
The latitude and longitude of the selected KMZ file appear in the LookAt field. (You can only see the beginning of the latitude unless you expand the default column width.)
- Click OK. You return to the Vector Project Editor.
- Select File > Save. Google Earth Enterprise Fusion saves the vector project with the same name.
Configure Display Rules for a Vector Project
This exercise covers how to specify display rules for your vector project. Display rules determine how your data looks in Google Earth EC.
Each resource in a project is known as a layer. Each layer can have one set of display rules. Each display rule includes feature and label formatting that you specify and one or more filters for the selected layer. The filters for each display rule determine which data in the layer to apply that formatting to. For example, in this exercise, you work with road data that includes major and minor highways. You might want the major highways to appear as blue lines and the minor highways as yellow lines. To accomplish that, you create two display rules for the layer--one for major highways and one for minor highways. The filter(s) for each rule determine which data are affected by that rule’s formatting specifications.
In this exercise, you create and modify a number of display rules for the CAHighways layer, so Google Earth EC displays the road information at the desired display levels with appropriate labels and coloring to distinguish between major freeways and other roads.
A key part of knowing how to configure display rules for vector data requires familiarity with the data fields in the source data. You can find information about the CAHighways layer of your vector project at this website:
https://nationalmap.gov/small_scale/mld/roadtrl.html
To configure a vector layer:
- In the Vector Project Editor, right-click CAHighways, and select Configure Display Rules from the context menu.
The Display Rules dialog appears with the Feature tab in the foreground and the default select all rule highlighted.
When you first create a vector project, the default display rule--default select all--is the only rule listed for each layer. The filter for the default rule has no matching criteria, so it matches all data. This rule is considered the catch-all rule. It is designed to catch all of the data that does not match any other rules you create.
Tip: Google Earth Enterprise Fusion executes the display rules sequentially, based on the order in which they are listed on the Rules list. So you should always make the default select all rule the last one on the list.
First, Google Earth Enterprise Fusion attempts to match the filter specified for the first rule to the data in the resource. Then it applies the formatting specified for that rule to any matching data.
Next, it attempts to match the filter specified for the second rule to the remaining data in the resource (that is, data not selected for the first filter). It applies the formatting specified for that rule to any matching data.
Then, it applies the formatting you specify for the default select all rule (or the default formatting, if you do not change it) to any data that does not match the previous rules on the list, if any. This ensures that all vector data for the layer is displayed.
Configure the Default Select All Rule
In this part of the exercise, you define the default select all rule. This rule applies to all of the surface streets that are left after the highways and freeways are covered by other rules. You define the additional rules for highways and freeways later in this exercise, because they are based on this default rule.
To define the default select all rule:
- Specify the geometry characteristics of the lines:
- For Draw Features As, select Lines.
- For Visibility, set the lower end of the range to 9, and the upper end of the range to 18.
- For Maximum Simplification Error, accept the default setting, 0.5.
- For Maximum Resolution Level, select 18. This sets visibility level and the point where the Google Earth Enterprise Fusion stops building the resource.
- Check the box next to Draw As Roads, and specify the options related to road labels:
- For Road Label Type, accept the default setting, Label.
- Under Draw Style, for Line Color, set it to bright red.
- For Line Width, enter 2.0.
- For Elevation/Height Mode, accept the default setting, Clamp to Ground.
These settings display the roads as red lines when Google Earth EC is zoomed in fairly close.
- In the Road Label section on the right:
- Click the empty text field. The Label Format dialog appears. This option allows you to specify the text that appears on the label.
- Click the Insert Field drop-down list to display the names of all of the fields in your source data.
- Select NAME from the list. The string «NAME» appears in the text field.
- Click OK. The string «NAME» appears in the Text field. The Display Rule dialog shows all of your selections. These settings result in Google Earth EC displaying the value of the NAME column for each road in your source data.
- Click OK to save your display rule.
- Verify that your display rule does what you intend:
- Ensure that nothing is listed in the Preview List pane. If one or more assets are listed, right-click any asset, and select Remove All Layers from the context menu; then click OK to confirm the removal.
- In the Vector Project Editor, check the box next to CAHighways.
- Right-click CAHighways, and select Zoom to Layer from the context menu.
No roads appear because your display level is approximately 7, and you set the visibility level to between 9 and 18 in the Display Rules dialog.
- Zoom in to a display level of just over 9. Red lines appear for the roads in the Preview pane.
Note: Labels for vector projects do not appear in the Preview pane.
- Zoom out to a display level less than 9. The roads disappear from the Preview pane.
- Save the vector project by selecting Save from the File menu in the Vector Project Editor.
This saves the project with the same name. If you want to save a project you create outside this tutorial with a different name, you can select Save As from the File menu, and follow the instructions in Add Resources to a Vector Project.
Note: Whenever you modify display rules or filters for your data, it is a good idea to save the project.
Display Rules for Major Freeways
This exercise guides you through creating the display rules necessary to achieve the desired appearance for the major freeways in the San Francisco Bay Area. When you finish this exercise, you should have a good understanding of the use of filters in managing complex data.
When setting display rules for vector data, it is critical that you are familiar with the source data you are working with and have an understanding of the fields used to classify different types of vector data. In the source data for this tutorial, the FEATURE column sorts the roads and highways into the following types:
- Principal Highway
- Other Through Highway
- Other Highway
- Limited Access Highway
In this exercise, you create a second filter and use the FEATURE column values to distinguish the limited access highways (major freeways) from other types of highways and roads, and then display them appropriately.
To define a display rule for major freeways:
- In the Vector Project Editor, right-click CAHighways, and select Configure Display Rules from the context menu.
The Display Rules dialog appears with the Feature tab in the foreground and the default select all rule highlighted.
- Click at the bottom-left of the dialog. The New Rule dialog appears.
- Enter Major Freeways in the New Rule Name field, and click OK. The new rule name appears on the Rules list below the default select all rule.
- Click to move the new rule up, so it appears before the default select all rule.
Because Google Earth Enterprise Fusion applies display rules in the order in which they appear on this list, the MajorFreeways rule must appear before the catch-all rule (default select all), which covers all data not covered by other rules.
- On the Feature tab, specify the geometry characteristics for the Major Freeways rule:
- For Draw Features As, select Lines.
- For Visibility, set the low end of the range to 9 and the high end of the range to 18.
- For Maximum Simplification Error, accept the default setting, 0.5.
- Check the box next to Draw as Roads (if it is not already checked).
- For Road Label Type, select Shield.
- Under Draw Style, for Line Color, set it to royal blue.
- For Line Width, enter 3.0.
- Under Elevation/Height, for Mode, accept the default, Clamp to Ground.
These settings display the roads as thick blue lines when Google Earth EC is zoomed in fairly close.
- In the Road Label section, accept the current settings.
- In the Road Shield section on the right, click the button next to Icon. The Icons dialog appears.
- Scroll down, and select shield1, and click OK.
The Display Rule dialog shows all of your selections.
- Click the Filter tab, and specify the filter for the Major Freeways rule:
- Accept the default selection, Match all of the following, at the top of the tab.
- Click More at the bottom of the tab.
Two drop-down lists and a text box appear on the list of filters.
- Select FEATURE from the left drop-down list.
- Select equals from the other drop-down list.
- Enter Limited Access Highway in the text field.
The Filter tab shows your selections.
- Click OK to save your changes to the display rule.
When this data is displayed in Google Earth EC, this filter causes the display settings on the Feature tab to be applied only to the road segments in your source data with the value Limited Access Highway in their FEATURE column.
- Verify that both filters and rules are working correctly:
- In the Vector Project Editor, check the box next to CAHighways, if it is not already checked.
- Zoom in to a display level between 9 and 18, if necessary.
Both thin red roads and thicker blue roads appear in the Preview pane. The thicker blue roads are the roads defined in the MajorFreeways filter, and the thinner red roads are the rest of the roads in the source data, which are defined by the default select all filter.
- Save the vector project by selecting Save from the File menu in the Vector Project Editor.
This saves the project with the same name.
Build a Vector Project
As with imagery and terrain projects, in this exercise, you build the vector project as soon as you finish configuring display rules.
- In the Asset Manager, right-click CARoads.
- Select Build from the context menu.
The status of the project immediately changes to Queued and then In Progress.
When the status of the vector project build is Succeeded, close the Asset Manager by clicking the close box (X), and go on to the next lesson.


Liverpool look to renew and expand Anfield
by BeSoccerAnfield stadium is one of very few football temple's left. With more than 130 years of history, it has obviously suffered in various ways and undergone several reforms and updates, but Liverpool seem to have something deeper in mind, to expand its capacity.
According to the 'BBS', the work will cost more than 100 million euros. "The aim is to create a bigger Anfield, which will allow more fans to watch some of the best games in European football in a world class stadium," Liverpool explained to the British media.
This is not the first time thay Anfield has faced a reform, but very few times has it done so on such a big scale as this. Anfield is a surviver, and, in this way it is intended that the more than 100 year-old stadium undergoes some changes.

Detailed Description
The QScrollEvent class is sent when scrolling.
The scroll event is sent to indicate that the receiver should be scrolled. Usually the receiver should be something visual like QWidget or QGraphicsObject.
Some care should be taken that no conflicting QScrollEvents are sent from two sources. Using QScroller::scrollTo is save however.
See also QScrollPrepareEvent and QScroller.
Member Type Documentation
enum QScrollEvent::ScrollState
This enum describes the states a scroll event can have.
| Constant | Value | Description |
|---|---|---|
QScrollEvent::ScrollStarted | 0 | Set for the first scroll event of a scroll activity. |
QScrollEvent::ScrollUpdated | 1 | Set for all but the first and the last scroll event of a scroll activity. |
QScrollEvent::ScrollFinished | 2 | Set for the last scroll event of a scroll activity. |

I'm writting this to warn ppl about the growing increase of research chemicals that are being pawned off as older and more established drugs.
Just about weekends ago 3 friends of mine met with a guy in the city, who said he had mescaline for sale. Now when we looked at the viles they were powder form. What struck me though is when he said the dosage to weigh it up at. It was all wrong, he said .03 was a dose and I argued that a common dose of mescaline was about .25, a huge differance. He went on that his guy told him that its really pure mescaline. I decided not to get into it and we purchased a few vials without anymore noise. Being a little skeptical as to what we bought we weighed it up as he suggested as to avoid any mishaps. Before leaving he also said NOT to snort any of it, which is also strange. I've never heard of mescaline that you couldn't snort.
A few hours later we get back into town and we all split up our capsules and went our own way. 4 hours later at about 12:30 2 of my friends call me up saying they've dosed and want me to stop on by my friends house to dose with them, even though they were already tripping. I wanted to wait till tomorrow after I got a good night sleep. But they were persistant and they needed somebody that knew how to roll joints under the influence of psychedelics. It was about 1am when I got there and we started a nice fire in the backyard to chill next to. They have already been tripping for 2 hrs before I got there. I dropped 1 capsule and they each dropped another about an hour after me.
The whole night went pretty good. The trip was alot like a good mescaline trip. The whole experience was very pleasant, with a great body buzz and good OEVs. And I kept wondering how I could be feeling like this off such a light dose if it was mescaline. Through the night both friends threw up several times and I told them that they shouldn't of ate anything for several hrs before dosing, but they're both impatient when it comes to taking psychedelics.
About 9am comes around and my one friend, seeming fine, just walks across the fire and stumbles onto the ground face first.  It wasn't funny anymore he was going into a seizure. I've seen someone have a mind seizure before that lasted 1 min tops. But this kid was going into a full blown seizure.  Then he started to convulse and was struggling with his breathing. My other friend asked if he should call an EMS and I told him to hurry. I tried to keep him on his side so he wouldn't choke or swallow his own tongue. After about 10 mins the first person on the scene isn't an EMS of course it's a sherrif.
This cop immediatly looks at the situation and looks for signs of criminal activity (drug abuse). This didn't help at all. His muscles were starting to relax and his breathing was regular again, except for the twitching. He finally opened his eyes and looked at me with a blank expression and asked where I came from. I told him I've been right here. Then he glanced at the cop over my shoulder and jumped up which really shocked me then staggered around as if trying to run and fell in a brush pile and started to relapse. Once me and the cop pulled him out and sat him down on a fold up chair. He started freaking out real bad.
Then my other friend came back with the ems finally. The medics did their thing and got him to calm down. He was responsive but not really there, kept wanting to get up and walk around. So the medics straped him down. Then the questions started, the cop started with his interrigation of the whole thing.  Me and my other friend didn't get searched, but were bombarded with questions. We told the cop that he got something at a party we were at the other night. He asked what it was, but we told him all we knew is it was a hallucinogen.  And he finally left as well.
After pumping his stomach and taking a blood test they didn't find anything that they knew of, so they sent the blood to a lab to do extensive research and the results came back with 2C-T-7. Something I've never done before. My friend is fine except being very well shaken up still. Also the other friend that split up earlier the day before had a friend that had a seizure after taking 1 capsule. His seizure was very brief and they didn't have to call for an ems.
I decided to write this to warn ppl especially if you live in the Detroit area (even farther if you come from smaller towns to the city for your hook, which most ppl do) where this psuedo mescaline is in heavy circulation right now. It looks like these research chemicals are starting to reach farther and farther. Earlier this spring at the DEMF (Detroit Electronic Music Festival) I ran into several ppl selling AMT and Foxy. The fact that these are research chemicals still and that not alot of ppl do their homework on new drugs makes for a dangerous cocktail. Tread carefully and know that when u roll the dice with the reaper the odds are always in his favor.

func HeaderValuesContainsToken(values []string, token string) bool
HeaderValuesContainsToken reports whether any string in values contains the provided token, ASCII case-insensitively.
func IsTokenRune(r rune) bool
func PunycodeHostPort(v string) (string, error)
PunycodeHostPort returns the IDNA Punycode version of the provided "host" or "host:port" string.
func ValidHeaderFieldName(v string) bool
ValidHeaderFieldName reports whether v is a valid HTTP/1.x header name. HTTP/2 imposes the additional restriction that uppercase ASCII letters are not allowed.
RFC 7230 says: header-field = field-name ":" OWS field-value OWS field-name = token token = 1*tchar tchar = "!" / "#" / "$" / "%" / "&" / "'" / "*" / "+" / "-" / "." / "^" / "_" / "`" / "|" / "~" / DIGIT / ALPHA
func ValidHeaderFieldValue(v string) bool
ValidHeaderFieldValue reports whether v is a valid "field-value" according to http://www.w3.org/Protocols/rfc2616/rfc2616-sec4.html#sec4.2 :
message-header = field-name ":" [ field-value ] field-value = *( field-content | LWS ) field-content = <the OCTETs making up the field-value and consisting of either *TEXT or combinations of token, separators, and quoted-string>
http://www.w3.org/Protocols/rfc2616/rfc2616-sec2.html#sec2.2 :
TEXT = <any OCTET except CTLs, but including LWS> LWS = [CRLF] 1*( SP | HT ) CTL = <any US-ASCII control character (octets 0 - 31) and DEL (127)>
RFC 7230 says:
field-value = *( field-content / obs-fold ) obj-fold = N/A to http2, and deprecated field-content = field-vchar [ 1*( SP / HTAB ) field-vchar ] field-vchar = VCHAR / obs-text obs-text = %x80-FF VCHAR = "any visible [USASCII] character"
http2 further says: "Similarly, HTTP/2 allows header field values that are not valid. While most of the values that can be encoded will not alter header field parsing, carriage return (CR, ASCII 0xd), line feed (LF, ASCII 0xa), and the zero character (NUL, ASCII 0x0) might be exploited by an attacker if they are translated verbatim. Any request or response that contains a character not permitted in a header field value MUST be treated as malformed (Section <IP_ADDRESS>). Valid characters are defined by the field-content ABNF rule in Section 3.2 of [RFC7230]."
This function does not (yet?) properly handle the rejection of strings that begin or end with SP or HTAB.
func ValidHostHeader(h string) bool
ValidHostHeader reports whether h is a valid host header.
func ValidTrailerHeader(name string) bool
ValidTrailerHeader reports whether name is a valid header field name to appear in trailers. See RFC 7230, Section 4.1.2

According to Northern Gateway risk assessments, the probability of a tanker spill of any size would be about 0.4 per cent in any given year. The company estimated the return period (average interval between events) would be 250 years for a marine spill. Northern Gateway said the probability of a full-bore rupture on the oil pipeline would be 0.2 per cent in a given year, based on an estimated return period of 464 years.
National Energy Board & Canadian Environmental Assessment Agency (2013-12-19) Joint Review Panel
One curiosity of their report is the risk numbers. Let us crunch their numbers for fun! This may be of interest as they should perhaps change their calculations in future. They calculated the expected time until the first spill, however the median time, for example, until a spill may be more informative.
Northern Gateway estimates the probability of a major spill on the pipeline is 0.2% ($p = 0.002$) per year; they double this risk on the tanker transport side ($p=0.004$). It is a simple calculation from there to show that the expected number of years until the first spill is 500 years.
That is, if $p$ is the probability of a spill each year, the expected time to the first spill, $\text{E}[s]$, is:
$$\text{E}[s] = \frac{1}{p}$$The probability of the first spill being in year $n+1$ is the probability there is no spill in the first $n$ years, $(1-p)^n$, times the probability, $p$, that there is a spill in year $n+1$. This makes the expected year in which the first spill occurs:
$$\text{E}[s] = \sum_{n=0}^\infty (n+1)(1-p)^np$$This fortunately is a well-known infinite sum. To obtain a closed form for it we need to make some observations. First note that, when $q<1$:
$$1 = \sum_{n=0}^\infty q^n - q( \sum_{n=0}^\infty q^n)$$so that
$$\frac{1}{(1-q)} = \sum_{n=0}^\infty q^n$$differentiating this with respect to $q$ gives:
$$\frac{1}{(1-q)^2} = \sum_{n=1}^\infty nq^{n-1} = \sum_{n=0}^\infty (n+1)q^n$$so that
$$\text{E}[s] = \frac{1}{(1-(1-p))^2}p = \frac{1}{p}$$Thus, the Joint Review Panel got their math correct, although they could revisit significant digits.
Interestingly, you can reverse this calculation! That is, if one has a pipeline with a first spill (assuming this has happened roughly at the expected value) one can calculate $p$. Consider the Kalamazoo oil spill in 2010, the largest on-land oil spill, and one of the costliest spills, in U.S. history. Of course, as it was maintained by the same company who is now proposing to build the Northern Gateway, it cannot be viewed as being completely irrelevant. This pipeline was described by the company as an aging pipeline. It was, in fact, built in the sixties so it was roughly 50 years old when it ruptured. Using this as baseline, this fixes the risk of a spill at 2% per year.
$$p = \frac{1}{\text{E}[s]} = \frac{1}{50} = 0.02$$This is interesting, as the review panel has therefore accepted the company's assertion that (due to improved technology) the probability of a spill has decreased by an order of magnitude (a factor of 10) since then. Furthermore, on the basis of this the review panel was happy to state that the first expected pipeline spill is in 500 years. Recalling that the Kalamazoo spill was in 2010 and it was the same company which was responsible for maintaining that line (in an easily accessible area), this is a significant improvement!
There is another aspect of this calculation that is interesting: the review panel supplied the expected value. An expected value is heavily influenced by large values with very low probabilities. It is possible, though unlikely, that there will not be a spill for thousands of years! As discussed above, this calculation is a summation of the probability of a spill over all years (i.e. an infinite sum), so there are lots of large values. A different calculation is of the median, which is the time at which there is a 50% probability a spill will already have occurred.
This suggests:
In fact, surely the panel should be thinking about the probability that there is no spill over the lifetime of the pipeline. Suppose the pipeline is to be decommissioned in 30 years, let us calculate the probability that there will be no spill in that time:
In order to gain insight into the potential risk of an oil spill, you can play with the parameters below! You can drag the blue highlighted numbers to adjust the interactive graph.
Let's say the probability of a spill is per year (Use Table 1). Let's say you are comfortable with a probability of not having a spill. With your risk tolerance and this probability, the pipeline should not be operated longer than years.
When the probability of a spill is the average interval between spills (the return period) as calculated by Northern Gateway is years. At years there is a chance there has already been an oil spill.

System Reference¶
In this section, we will cover the features of each following systems in-depth listed below:
Group Permission¶
Group Permission sets the permission of a user group handled by an administrator.
Here are the following fields in this system:
- Group Permission - Returns the ID number of itself
- Dashboard Menu - Fetches the name of the model
- User Group - Fetches the name of the group
- Read - Sets the Read access to the user
- Add - Sets the Add access to the user
- Edit - Sets the Edit access to the user
- Delete - Sets the Delete access to the user
First of all, make it sure that your existing account is not an Admin (example below is Even Demata) and it is part of the User Group (example below is Front Desk).
Click the Front Desk highlighted below.
Go to the Group Permission tab. Afterwards, click Add New Group Permission button at the right side.
Set the Dashboard Menu to “Todos” model, User linked to “Even Demata”, and activate the “Read” only. It means Front Desk User Group has restricted access to adding, editing and deleting a record in the Todos model.
Result
Log out your System Admin account. This time login your username and password using the user account that has group permission. Now click on TODOS model.
As you will see, your user account is restricted to add, edit, or delete a record in the Todo model. You can only read what is inside this model.
To remove these restrictions, login your System Admin account, go to Group Permission and activate “Add”, “Edit”, and “Delete” access to Front Desk group.
Login your Even Demata account and see what happens.
Let’s open the “Read a book” record to see if the user can have access to edit.
Nice! You have full access to everything in the TODOS model. What if the user group has no access to “Read” but can add, edit, or delete a record? Login your System account and remove “Read” access to Front Desk.
Login your Even Demata account and see what happens.
TODOS model does not show up in the dashboard. Even if you remove access to “Add”, “Edit” and “Delete” to Front Desk group, it will display the same output.
Login your System Admin account. Finally, delete the Group Permission in the Front Desk User Group.
Well done! Now you know how to set the group permission to the user group, changing the access in the model and deleting the group permission.
Language¶
Language is a system in uAdmin that is used to add, modify, and delete the elements of a language. There are a total of 184 languages.

Here are the following fields in this system:
- Language - Tag for a specific language
- English Name - International name
- Name - Local name
- Active - If you want to activate the language in your application
- Available in GUI - If you want to make the language available in the GUI
First of all, go to the Dashboard Menus.
Select Todos model in the list.
As you notice, English (en) is the only language available in the field.
If you want to add more languages to show in the Dashboard Menu, go to the Languages in the uAdmin dashboard.
Let’s say I want to add Chinese and Tagalog in the menu name of the Todo model. In order to do that, set the Active as enabled.
Now go back to the Dashboard Menus, select Todos model in the list and you will notice that Chinese (zh) and Tagalog (tl) are added in the Menu Name field. Put your translated text into the related language manually.
 Set your language to 中文 (Zhōngwén), 汉语, 漢語 (Chinese).
When you notice, the Todos model is now translated to Chinese. That’s cool!
Now log out your account then login again. This time set your language to Wikang Tagalog (Tagalog) and let’s see what happens.
Result
Nice! The Todos model is successfully translated to Tagalog.
Now let’s try something more. Go to the Languages, search for Vietnamese, and set it as Default and Active.
Log out your account, refresh your browser several times and see what happens.
It automatically sets the value of the Language field to Tiếng Việt (Vietnamese).
Login your account again, go to the Languages, search for Arabic, and activate RTL (Right-to-left) and Active.
Log out your account then login again. Set your language to (Arabic) العربية and let’s see what happens.
The login page has aligned from right to left.
Even if you go to any models in the dashboard (example below is Dashboard Menus), it aligns the form automatically from right to left.
Well done! Now you know how to activate your languages, set it to default, and using RTL (Right-to-left).
Log¶
Log is a system in uAdmin that is used to add, modify, and delete the status of the user activities. It keeps track of many things by default.
Here are the following fields in this system:
- Log - Returns the ID number of itself
- Username - An identification used by a person
- Action - See uadmin.Action for more details.
- Table Name - The name of the model
- Table - ID number of the table
- Activity - This shows you what are the fields that you put in your record. It also adds one field for the IP “_IP” the user was using for security.
- Roll Back - Undo the changes for edit and delete logs
- Created At - Displays the date where the log was created
Let’s open our app to see how these things work. Login your account using “admin” as username and password.
Go to “LOGS” model in your dashboard.
You will notice that you have logs for the action “Login Successful” that you have taken in your app which is what we have done a while ago. Log is served as the history of all your activities in your app.
If you open any of these logs, you will see all the details of that log:
The activity is the main part of your log. This shows you what are the fields that you put in your record. It also adds one field for the IP “IP” the user was using for security.
Let’s go back to the previous page, refresh your browser and see what happens.
Result
You will notice that there is another type of action called “Read” using the admin account because we opened a record in the log table.
Go back to the uAdmin Dashboard and open “TODOS” model.
Click Add New TODO.
Fill up the fields like in the example below:
Save it and new data will be added to your model.
Open your created record in Todo model. Notice that you have a “History” button when you open any record:
This “History” button will give you logs related to this record:
As you notice, the logs keep track of what we have added in the Todo model as well as we have opened a while ago.
Open “TODOS” model and let’s change the record from “Read a book” to “Read a magazine”.
Now if I go to “LOGS”, you will notice that the action says we “Modified” a record in the todo table. There’s also a Rollback button which means we can undo any changes.
Click on “Roll Back” and see what happens.
You will not see anything in the screen except the white background. To fix this, type <IP_ADDRESS>:8000 in the address bar. Once you are done, you will see the uAdmin dashboard again. Open “TODOS” model.
You will notice that the name field has reverted from “Read a magazine” to “Read a book”.
Let’s delete a record in the Todo model.
Now if I go to “LOGS”, you will notice that the action says we “Deleted” a record in the todo table. There’s also a Rollback button which means we can undo any changes. This is a good feature for the user who accidentally delete their records in the model.
Click on “Roll Back” and see what happens.
You will not see anything in the screen except the white background. To fix this, type <IP_ADDRESS>:8000 in the address bar. Once you are done, you will see the uAdmin dashboard again. Open “TODOS” model.
As expected, we recovered a record in the Todo model.
Now click the profile icon on the top right corner then choose “Logout”.
Input your username and password that is not existing in the User System Model then click Login.
You will see an error that says “Invalid Username”. Now login using “admin as username and password.
Now go to “LOGS” again. If you scroll it down, you will notice that your logout and login denied actions were recorded in the list.
Go back to the uAdmin Dashboard then select “USERS”.
Choose System Admin account then input your email. Email is necessary for exchanging messages between people or for password recovery.
Make it sure that you have a ready-made email configurations in main.go.
func main(){
uadmin.EmailFrom =<EMAIL_ADDRESS>uadmin.EmailUsername =<EMAIL_ADDRESS>uadmin.EmailPassword = "abc123"
uadmin.EmailSMTPServer = "smtp.integritynet.biz"
uadmin.EmailSMTPServerPort = 587
// Some codes
}
Once you are done, rebuild your application first (if you haven’t set the email configurations yet) before you log out your account. At the moment, you suddenly forgot your password. How can we retrieve our account? Click Forgot Password at the bottom of the login form.
Input your email address based on the user account you wish to retrieve it back.
Once you are done, open your email account. You will receive a password reset notification from the Todo List support. To reset your password, click the link highlighted below.
You will be greeted by the reset password form. For now, try not to match the new and confirm reset password and see what happens.
Result
In uAdmin, you can only use one reset password per key. In this case, go back to the login form, select Forget Password, type your email to resend the request. This time input the following information that does match in order to create a new password for you.
Once you are done, you can now access your account using your new password.
 That’s how powerful the uAdmin log is, the way it keeps track of many things.
Logs can accumulate so fast and it will get harder to find specific actions when you need to like when conducting an audit and investigating something in your system. Use “Filter” to narrow down what you are looking for:
Congrats, now you know how to understand records you have in your app and how to audit them and revert back actions when you need to.
Profile¶
uAdmin has a feature that allows you to customize your own profile. In order to do that, click the profile icon on the top right corner then select admin highlighted below.
By default, there is no profile photo inserted on the top left corner. If you want to add it in your profile, click the Choose File button to browse the image on your computer.
Once you are done, click Save Changes on the left corner and refresh the webpage to see the output.
No matter what small or large the pixels you upload in your profile, it will automatically resize the photo to static format.
You can also enable two factor authentication in your profile by using Google authenticator. In uAdmin, it uses QR code which is typically used for storing URLs or other information for reading by the camera on a smartphone.
If there is a problem, you may go to your terminal and check the OTP verification code for login.
Session¶
Session is an activity that a user with a unique IP address spends on a Web site during a specified period of time. [1]
Here are the following fields in this system:
- Key - Displays a random string
- User - Returns the first and last name
- Login Time - This is when the user logins to the dashboard.
- Last Login - This is when the user has last access to the account.
- Active - If it is not checked, you will not be able to login with that user.
- IP - Numerical label assigned to the session from the address bar that user connects to
- Pending OTP - If the user has not verifying the OTP in the login
- Expires On - This is when the cookie will expire.
Let’s open our app to see how these things work. Login your account using “admin” as username and password.
The Session model is hidden in the uAdmin Dashboard by default. In order to show it, go to “DASHBOARD MENUS” first.
Select Sessions model in the list.
Turn off the Hidden field so that the Session model will become visible in the uAdmin Dashboard.
Go back to the uAdmin Dashboard and open “SESSIONS”.
If this is your first time to run an application, you will see only one session in the list as shown below.
If you open the record, you will see all the details of that session. Let’s turn off the Active, save it and see what happens.
It will automatically redirect you to the login page which means your session has been deactivated. Login your account again using “admin” as username and password.
Your session automatically generates a new key for you.
Before we proceed to Pending OTP, go to the uAdmin Dashboard and select “USERS”.
Choose System Admin and activate the OTP required.
Now go back to Sessions model then click the previous record.
Enable the “Active” and “Pending OTP” then click Save.
Now log out your account. Login again using “admin” as username and password then see what happens.
You will be asked to input a verification code in the login form. Check your terminal to see the OTP code.
[ INFO ] User: admin OTP: 245421
Open “SESSIONS” model. You will notice that the second session is no longer active after you logout. The last login has changed because you reuse that session. It was reused because you set that session as Active before you logout. Lastly, the Pending OTP is no longer checked because you already verified OTP code given by your terminal.
Finally, set the Expires On value to now.
Warning
Use it at your own risk. Once the session expires, your account will be permanently deactivated. In this case, you must have an extra user account in the User database.
Save it and see what happens.
It will automatically redirect you to the login page which means your session has expired. In this case, you must login using another account that has no expiry date in the session.
Well done! Now you know how to configure your sessions by using Active, Pending OTP, and Expires On.
User¶
User is a system in uAdmin that is used to add, modify and delete the elements of the user. By default, the system creates one user which is the admin user who has full permission to read, add edit and delete data from every model.
Here are the following fields in this system:
- User - Returns the first and last name
- Username - An identification used by a person
- First Name - Given name
- Last Name - Surname
- Email - An electronic mail address used for exchanging messages between people or for password recovery
- Active - If it is not checked, you will not be able to login with that user.
- Admin - Allows full access to everything where you can set permissions to the user
- Remote Access - If it is not checked, you will only be able to login if you are connected to the server using a private IP e.g. (10.x.x.x,192.168.x.x, 127.x.x.x or ::1).
- User Group - To belong a specific user to the group. If the user group has permissions, the user can access to something with some restrictions.
- Photo - This is where you can upload your profile picture in your account.
- Last Login - This is when the user has last access to the account.
- Expires On - This is when the cookie will expire.
- OTP Required - Adds an extra layer of security by sending the verification code
Let’s create a new user account called “even” with the First Name “Even” and the Last Name “Demata”. Set the Active, Admin, and Remote Access fields to true.
Result
Now log out your account and login again using the name “even”.
As expected, you will see the same dashboard like using your System Admin account. It’s because you are an admin and has full permissions to everything. For now, let’s set an email address to<EMAIL_ADDRESS>Make it sure that you have set an email configurations in main.go.
func main(){
uadmin.EmailFrom =<EMAIL_ADDRESS>uadmin.EmailUsername =<EMAIL_ADDRESS>uadmin.EmailPassword = "abc123"
uadmin.EmailSMTPServer = "smtp.integritynet.biz"
uadmin.EmailSMTPServerPort = 587
// Some codes
}
Log out your account. At the moment, you suddenly forgot your password. How can we retrieve our account? Click Forgot Password at the bottom of the login form.
Input your email address based on the user account you wish to retrieve it back.
Once you are done, open your email account. You will receive a password reset notification from the Todo List support. To reset your password, click the link highlighted below.
You will be greeted by the reset password form. Input the following information in order to create a new password for you.
Once you are done, you can now access your account using your new password.
Login your System Admin account. Turn off the Admin and Remote Access fields in Even Demata account.
Logout your System Admin account and login the Even Demata account. Let’s see what happens.
The dashboard menu is empty. How can we get access to it at least some of them? We need to set the user permission to Even Demata account so login your System account, go to Users model, select Even Demata account then go to the User Permission tab. Afterwards, click Add New User Permission button at the right side.
Set the Dashboard Menu to “Todos” model, User linked to “Even Demata”, and activate the “Read” only. It means Even Demata user account has restricted access to adding, editing and deleting a record in the Todos model.
Result
Log out your System Admin account. This time login your username and password using the user account that has user permission. Afterwards, you will see that only the Todos model is shown in the dashboard because your user account is not an admin and has no remote access to it. Now click on TODOS model.
As you will see, your user account is restricted to add, edit, or delete a record in the Todo model. You can only read what is inside this model.
Login your System Admin account again, go to the User Group and create a group named “Front Desk”.
Link your created user group to Even Demata account.
Afterwards, click the Front Desk highlighted below.
Go to the Group Permission tab. Afterwards, click Add New Group Permission button at the right side.
Set the Dashboard Menu to “Todos” model, User linked to “Even Demata”, and activate the “Add” only. It means Even Demata user account has restricted access to reading, editing and deleting a record in the Todos model.
Result
Log out your System Admin account. This time login your username and password using the user account that has group permission. Now click on TODOS model.
As you will see, your user account is still restricted to add, edit, or delete a record in the Todo model even if your group permission has access to “Read” only. It’s because the user permission has no access to “Read” even if Even Demata is part of the Front Desk group. In other words, user permission prioritizes more than group permission.
Login your System Admin account again. Go back to the Users model, select Even Demata account, and let’s upload a profile picture. If you don’t have any pictures or icons in your computer, I would recommend you to go over flaticon.com, but you can browse anywhere online. Once you search for an icon, download the PNG version and choose the size 128 pixels.
Logout your System Admin account. Login your Even Demata account, click on profile icon then select “even” highlighted below.
You will notice that your profile picture has been uploaded in your user account.
Login your System Admin account again. Go back to the Users model, select Even Demata account, and activate the OTP Required.
Logout your System Admin account then Login Even Demata account. Afterwards, you will see the second form as shown below. It requires you to input a Verification Code given by your terminal.
Terminal
[ INFO ] User: even OTP: 812567
Once you are done, it will redirect you to the uAdmin dashboard. Login your System Admin account again, go back to the Users model, select Even Demata account, and set the Expires On to now.
Log out your System Admin account, login Even Demata account and see what happens.
It will log you out automatically because Even Demata account has already expired.
Login your System Admin account. Go to Users model and finally, delete the Even Demata account.
Well done! Now you know how to configure your user by adding, updating, customizing and deleting a user account.
User Group¶
User Group is a system in uAdmin used to add, modify, and delete the group name, the only field in this system. It has only one field: Group Name. It is useful if you want to belong a specific user to the group. If the user group has permissions, the user can access to something with some restrictions.
Let’s create a new user group named “Front Desk”.
Afterwards, link it to any of your existing user accounts.
Result
Finally, delete the Front Desk User Group.
Well done! Now you know how to add a user group, link it to your existing user accounts, and deleting the user group.
User Permission¶
User Permission sets the permission of a user handled by an administrator.
Here are the following fields in this system:
- User Permission - Returns the ID number of itself
- Dashboard Menu - Fetches the name of the model
- User - Fetches the first and last name of the user
- Read - Sets the Read access to the user
- Add - Sets the Add access to the user
- Edit - Sets the Edit access to the user
- Delete - Sets the Delete access to the user
First of all, make it sure that your existing account is not an Admin (example below is Even Demata).
Set the Dashboard Menu to any of your existing models (example below is Todos), link it to any of your existing accounts, and activate the “Read” only. It means Even Demata account has restricted access to adding, editing and deleting a record in the Todos model.
Result
Log out your System Admin account. This time login your username and password using the user account that has user permission. Afterwards, you will see that only the Todos model is shown in the dashboard because your user account is not an admin and has no remote access to it. Now click on TODOS model.
As you will see, your user account is restricted to add, edit, or delete a record in the Todo model. You can only read what is inside this model.
To remove those restrictions, login your System Admin account, go to User Permission and activate “Add”, “Edit”, and “Delete” access to Even Demata account.
Login your Even Demata account and see what happens.
Let’s open the “Read a book” record to see if the user can have access to edit.
Nice! You have full access to everything in the TODOS model. What if the user has no access to “Read” but can add, edit, or delete a record? Login your System account and remove “Read” access to Even Demata.
Login your Even Demata account and see what happens.
TODOS model does not show up in the dashboard. Even if you remove access to “Add”, “Edit” and “Delete” to Even Demata account, it will display the same output.
Login your System Admin account. Finally, delete the User Permission in Even Demata account.
Well done! Now you know how to set the user permission to the user account, changing the access in the model and deleting the user permission.

DANTE'S PEAK A film review by Walter Frith Copyright 1997 Walter Frith
I must confess that before I went to see 'Dante's Peak' I was expecting it to be a repetitive disaster movie fashioned after the succes of last year's 'Twister'. A quick studio cash grab to capitalize on the tremendous box office rewards reaped by that film. 'Twister' has made well over two hundred million dollars and there are usually copycats abound after a hit like that.
'Dante's Peak' is nothing like 'Twister'. It's a film that builds momentum slowly before unleashing its fury of special effects. 'Twister' took a dive right at the beginning and was nothing more than a lamentable chase picture and gave us characters we never really cared about where as 'Dante's Peak' is a thoughtful rendition of characters and technical academics blended nicely for pure entertainment courtesy of director Roger Donaldson ('The Bounty', 'No Way Out'.)
The town of 'Dante's Peak' is on the verge of a major volcanic eruption after lying dormant for quite a while. A geologist (Pierce Brosnan) who lost his wife in a volcanic disaster in Columbia four years earlier is sent by his superior along with a research team to investigate disturbing activity around that area. Brosnan is convinced that the town is in for a major eruption but his superior and the town's politicians urge him not to jump to any conclusions which could upset major economic plans to be set in motion by a businessman who will pump eighteen million dollars into the local economy and create about eight hundred jobs. Should word of a natural disaster get out, then they can kiss the cash goodbye. The town's mayor (Linda Hamilton) leans towards Brosnan's theory of a disaster brewing but goes along with the majority and puts off alerting the town.
This movie has state of the art special effects which are truly convincing and eye popping. If you think the movie will only display visual effects of volcanic activity, you are very wrong. Bridges collapsing, hydro lines falling, buildings breaking apart and mine shafts in chaos are only a few goodies to enhance the audience's viewing enjoyment.
In film, the rule of suspension of disbelief should be applied to truly enjoy 'Dante's Peak' but it is a slam bang adventure film which takes its time to get where its going and never looks back once its there.

CHLOROMYCETIN- chloramphenicol ointment
PARKE-DAVIS
Bone marrow hypoplasia including aplastic anemia and death has been reported following topical application of chloramphenicol. Chloramphenicol should not be used when less potentially dangerous agents would be expected to provide effective treatment.
Each gram of Chloromycetin Ophthalmic Ointment, 1% contains 10 mg of chloramphenicol in a special base of liquid petrolatum and polyethylene. It contains no preservatives. Sterile ointment.
The chemical names for chloramphenicol are:
(1) Acetamide, 2,2-dichloro-N-[2-hydroxy-1-(hydroxymethyl)-2-(4-nitrophenyl) ethyl]-, and
(2) D-threo-(—)-2,2-Dichloro-N-[β-hydroxy-α-(hydroxymethyl)-p-nitrophenethyl] acetamide.
Chloramphenicol has the following empirical and structural formulas:
Chloramphenicol is a broad-spectrum antibiotic originally isolated from Streptomyces venezuelae. It is primarily bacteriostatic and acts by inhibition of protein synthesis by interfering with the transfer of activated amino acids from soluble RNA to ribosomes. It has been noted that chloramphenicol is found in measurable amounts in the aqueous humor following local application to the eye. Development of resistance to chloramphenicol can be regarded as minimal for staphylococci and many other species of bacteria.
Chloramphenicol should be used only in those serious infections for which less potentially dangerous drugs are ineffective or contraindicated. Bacteriological studies should be performed to determine the causative organisms and their sensitivity to chloramphenicol (see Boxed Warning).
Chloromycetin Ophthalmic Ointment, 1% (Chloramphenicol Ophthalmic Ointment, USP) is indicated for the treatment of surface ocular infections involving the conjunctiva and/or cornea caused by chloramphenicol-susceptible organisms.
The particular antiinfective drug in this product is active against the following common bacterial eye pathogens:
Staphylococcus aureus
Streptococcus, including Streptococcus pneumoniae
Escherichia coli
Haemophilus influenzae
Klebsiella/Enterobacter species
Moraxella lucunata
(Morax-Axenfeld bacillus)
Neisseria species
This product does not provide adequate coverage against:
Pseudomonas aeruginosa
Serratia marcescens
The prolonged use of antibiotics may occasionally result in overgrowth of nonsusceptible organisms including fungi. If new infections appear during medication, the drug should be discontinued and appropriate measures should be taken.
In all serious infections the topical use of chloramphenicol should be supplemented by appropriate systemic medication.
Blood dyscrasias have been reported in association with the use of chloramphenicol (see WARNINGS).
Allergic or inflammatory reactions due to individual hypersensitivity and occasional burning or stinging may occur with the use of Chloromycetin Ophthalmic Ointment.
A small amount of ointment placed in the lower conjunctival sac every three hours, or more frequently if deemed advisable by the prescribing physician. Administration should be continued day and night the first 48 hours, after which the interval between applications may be increased. Treatment should be continued for at least 48 hours after the eye appears normal.
N 0071–3070–07
Chloromycetin Ophthalmic Ointment, 1% (Chloramphenicol Ophthalmic Ointment, USP) is supplied, sterile, in ophthalmic ointment tubes of 3.5 grams.

Barcelonians crash. A lot.
Wouldn't it be cool to see all the car accidents on one map? Yes, that would be awesome. HERE's every Barcelona car accident from 2010 to 2014.
With so many accidents, you might be thinking, "how can I avoid getting in a wreck?" You won't find the answer here, but you might start by avoiding the most dangerous intersection in Barcelona...
And the winner goes to...
You guessed it: Avinguda Diagonal and Passeig de Gracia.
From 2010 to 2014, there were 129 accidents involving 165 victims and 248 vehicles. That's an average of one accident every two weeks.
But everywhere is kind of dangerous
The reality is that, relative to other comparable cities, Barcelona is a dangerous place. Sure, Rome is worse (who's surprised?), but Barcelona's got a lot of cars, a lot of motorcycles, a lot of old roads, and a lot of people trying to get from point A to point B. And all that commotion adds up - to an average of 9,235 accidents per year over the last 5 years, which sums up to more than 25 per day.
And it doesn't appear to be getting any better
In 2010, there were just a hair over 9,000 accidents. In 2011, that number dropped to 8,809. Since then, however, the number of accidents has climbed by a few hundred per year, peaking at 9,660 in 2014 (the last year for which data are available).
When do accidents happen?
As consistent as the yearly numbers are, there's a lot of variation by time and day. Afternoon is far worse than morning, for example. In the below chart, you can make out spikes at around 8-9 AM (morning rush hour), 2 PM (afternoon break) and 5-7 PM (evening rush hour). It's odd that the mid-day spike is so much higher than the morning and evening spikes - are that many people on the road at that time?Weekdays (especially Friday) are far worse than weekends.
When we look at the averages over the course of an entire week, we see that weekdays have a pre-midnight spike (coming home from dinner), which is conspicuously absent on weekends.
It also seems that most of the Friday spike can be attributed to the AM - not PM - rush. Strange...
Like stars in the night sky
Car accidents are a pretty morbid topic. They take far too many lives, and cause countless suffering by those affected.
Data visualization can help us to absorb numbers too large for our primate brains (ie, the tens of thousands of car accidents in Barcelona over the last few years, and the hundreds of associated deaths). So, we'll end this post with a visual: click on the below image and zoom in - white dots are accidents, and red dots are deaths.
Data sources, code, etc.
OpenDataBCN hosts the dataset for traffic accidents managed by the Guardia Urbana. It's a super interesting dataset with a lot more than what was explored here (mortality, number of injuries, etc.).
The code and data for this post (including source files, cleaning script, visualizations, etc.) can all be found on github.


Depth-first search is named as such because the search traverses the entire height of a node before going to the next sibling node.
The general recursive pattern for traversing a binary tree is this: At
node N
do the following:
N
again.
N
again.
N
itself.These steps can be done in any order. If (L) is done before (R), the process is called left-to-right traversal, otherwise it is called right-to-left traversal.
The following methods show left-to-right traversal: pre-order, in-order and post-order.
Pre-order: 11, 7, 5, 3, 6, 9, 8, 10, 15, 13, 12, 14, 20, 18, 25
The pre-order traversal is topologically sorted (linear order), because a parent node is processed before any of its child nodes is done.
In-order: 3, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 18, 20, 25
In a binary search tree, in-order traversal retrieves data in sorted order.
Post-order: 3, 6, 5, 8, 10, 9, 7, 12, 14, 13, 18,25, 20, 15, 11

public func constraintsGreaterThanOrEqualTo(view: UIView) -> Self
-
Specifies that constraints should be generated defining the anchor group’s attributes as less than or equal to the view’s anchor group of the same kind.
Declaration
Swift
public func constraintsLessThanOrEqualTo(view: UIView) -> Self
-
Specifies that constraints should be generated defining the anchor group’s attributes as equal to the view controller’s anchor group of the same kind.
Declaration
Swift
public func constraintsEqualTo(viewController: UIViewController) -> Self
-
Specifies that constraints should be generated defining the anchor group’s attributes as greater than or equal to the view controller’s anchor group of the same kind.
Declaration
Swift
public func constraintsGreaterThanOrEqualTo(viewController: UIViewController) -> Self
-
Specifies that constraints should be generated defining the anchor group’s attributes as less than or equal to the layout guide’s anchor group of the same kind.
Declaration
Swift
public func constraintsLessThanOrEqualTo(viewController: UIViewController) -> Self
-
Specifies that constraints should be generated defining the anchor group’s attributes as equal to the layout guide’s anchor group of the same kind.
Declaration
Swift
public func constraintsEqualTo(layoutGuide: UILayoutGuide) -> Self?
-
Specifies that constraints should be generated defining the anchor group’s attributes as greater than or equal to the layout guide’s anchor group of the same kind.
Declaration
Swift
public func constraintsGreaterThanOrEqualTo(layoutGuide: UILayoutGuide) -> Self?
-
Specifies that constraints should be generated defining the anchor group’s attributes as less than or equal to the layout guide’s anchor group of the same kind.
Declaration
Swift
public func constraintsLessThanOrEqualTo(layoutGuide: UILayoutGuide) -> Self?
-
Activates constraints defined by the anchor group. Disables
translatesAutoresizingMaskIntoConstraints
on views as needed. Uses the.UpdateExisting
constraint activation policy, so when possible, existing constraints will be used with updated constants and/or priorities.Declaration
Swift
public func activate() -> [NSLayoutConstraint]
Return Value
The newly activated or updated constraints.
-
Deactivates any existing constraints that would have been activated by calling
activate()
. Useful when reconfiguring constraints.Declaration
Swift
public func deactivate()
-
Activates constraints defined by the anchor group. Disables
translatesAutoresizingMaskIntoConstraints
on views as needed. With the.UpdateExisting
constraint activation policy, existing constraints will be used with updated constants and/or priorities whenever possible. With the.IgnoreExisting
constraint activation policy, existing constraints will not be affected. Use this for installing multiple similar constraints with different layout priorities. - returns: The newly activated or updated constraints.Declaration
Swift
public func activate(policy: CLKEquivalentConstraintPolicy) -> [NSLayoutConstraint]
Return Value
The newly activated or updated constraints.
