"The Dahlia is the official flower of San Francisco" is the proud by-line of the Dahlia Society of California Bulletin in 1926. Rightly so, because on October 4, 1926 the San Francisco Board of Supervisors under the leadership of the then Mayor Rolph, without a dissenting vote, adopted the following resolution.
WHEREAS, the Dahlia has reached its highest perfection in and about San Francisco, and because Dahlias originated in San Francisco are grown in gardens all over the world; and
WHEREAS, the Dahlia partakes essentially of the character of our beloved city, in birth, breeding and habit, for it was originally Mexican, carried thence to Spain, to France and England in turn, being changed in the process from a simple daisy-like wild flower to a cosmopolitan beauty. It has come back to San Francisco like the sophisticated world traveler it is, to find its favorite home here, where it thrives in the cool summers and the moist air of our fog-swept, sandy gardens by the sea;
WHEREAS, it is a robust flower, generous and able to thrive in any reasonable soil, so long as it is not too dry, and has the primitive strength of our pioneer ancestors, together with the gayety and color that no other city nor flower can hope to equal, going, like our artists and poets, to carry color and beauty into far climes, but blooming best in our own gardens out of doors in our cool even climates;
WHEREAS, in its versatility, its beauty, its infinite variety of color and form, it is the very symbol of San Francisco life and of the spirit of her people; therefore, be it
RESOLVED, That the Dahlia be and it is here designated the official flower of San Francisco.

Conditions in Oxygen: how show/hide content based on UTM tags?
Starting from version 2.4, Oxygen has a powerful and useful "Conditions" functionality. More details can be found in the official documentation. Using the conditionals feature, we can now hide or show certain site content depending on the fulfilment of conditions. This can be useful, for example, to create hidden content only for subscribers of the site, or to create paid closed sections. In addition to the 26 built-in conditions, we can now create unique conditions using the API.
Cases of using conditions may be different and are limited only by your need and imagination. In this tutorial, I want to share with you my experiment on hiding content based on UTM tags. See an example of how this works.
I'm still testing it, but it seems to be working well. And so, I tell you how to do it step by step.
Step 1
Install the Code Snippets plugin, if you haven't installed it yet. We will need to add a small amount of PHP code to register our conditions.
Step 2
Create a new snippet Snippets > Add new (for example, I called it "Testing UTM-tags", but you can give it any name you need). In the snippet field, paste the following code and save the changes:
if( function_exists('oxygen_vsb_register_condition') ) {
 oxygen_vsb_register_condition('UTM source', array('options' => array(), 'custom' => true), array('=='), 'utm_source_callback', 'UTM');
 function utm_source_callback($value, $operator) {
 if (isset($_GET['utm_source'])){
 $utm_source = $_GET['utm_source'];
 setcookie("utm_source", $utm_source, $expire);
 return oxy_condition_eval_int($utm_source, $value, $operator);
 oxygen_vsb_register_condition('UTM medium', array('options' => array(), 'custom' => true), array('=='), 'utm_medium_callback', 'UTM');
 function utm_medium_callback($value, $operator) {
 if (isset($_GET['utm_medium'])){
 $utm_medium = $_GET['utm_medium'];
 setcookie("utm_medium", $utm_medium, $expire);
 return oxy_condition_eval_string ($utm_medium, $value, $operator);
 oxygen_vsb_register_condition('UTM campaign', array('options' => array(), 'custom' => true), array('=='), 'utm_campaign_callback', 'UTM');
 function utm_campaign_callback($value, $operator) {
 if (isset($_GET['utm_campaign'])){
 $utm_campaign = $_GET['utm_campaign'];
 setcookie("utm_campaign", $utm_campaign, $expire);
 return oxy_condition_eval_string ($utm_campaign, $value, $operator);
 oxygen_vsb_register_condition('UTM content', array('options' => array(), 'custom' => true), array('=='), 'utm_content_callback', 'UTM');
 function utm_content_callback($value, $operator) {
 if (isset($_GET['utm_content'])){
 $utm_content = $_GET['utm_content'];
 setcookie("utm_content", $utm_content, $expire);
 return oxy_condition_eval_string ($utm_content, $value, $operator);
 oxygen_vsb_register_condition('UTM term', array('options' => array(), 'custom' => true), array('=='), 'utm_term_callback', 'UTM');
 function utm_term_callback($value, $operator) {
 if (isset($_GET['utm_term'])){
 $utm_term = $_GET['utm_term'];
 setcookie("utm_term", $utm_term, $expire);
 return oxy_condition_eval_string ($utm_term, $value, $operator);
In this example, I set the cookie lifetime to 5 days. This means that if a user comes to the site via a link with a UTM tag, then each time he visits the page, conditions will work until 5 days have passed, or until he clears the cookie in his browser.
If you need to set cookies for a longer or shorter period, then on each line $expire=time()+60*60*24*5; replace 5 on the value that you need (in days). To save cookies for a specific condition or not, we will configure further in the next step.
Step 3
After registering conditions at the second step, in the list of conditions in the Oxygen editor, we should have new conditions: UTM source, UTM medium, UTM campaign, UTM content and UTM term. Next, we need to adjust the conditions for hiding / showing a block with content depending on our conditions.
Suppose that we need to track the source (utm_source tag) from Google ads. Our link with the UTM can look like this:{network}&utm_content={creative}&utm_term={keyword}
Now we need to create a condition, if the source is Google, then show on the page a special block that is initially hidden.
Variant 1: without tracking cookies
In this case, the block will be shown every time, but only if the link has an UTM tags. If the user enters this same page without any tags, the block will not be shown.
Create a condition for our block by selecting from the list - UTM source and writing a word equal to the value of the tag - google.
Oxygen Conditions: how show/hide content based on UTM tags?
Save the result and check.
Thus, we can track the value of any of the UTM tags (not just utm_source).
Variant 2: with cookie tracking
In this case, the block will be shown when you first visit the link with UТM. If you refresh the page, or visit the page without the UTM tags, the block will still be shown to the user over the entire lifetime of the cookie (in our example, this is 5 days, or until the user clears the cookie itself).
To do this, we will definitely need to change the condition type to OR and add an additional standard Cookie List condition in which we need to specify the value corresponding to the value of our UTM tag:
Set type Oxygen Conditions
set cookie conditions in Oxygen
Now the block will be displayed only if the url contains the word google OR cookies contains the word google.
That's all. I hope this article has been helpful to you.
Hey. This block is shown because you clicked a link with a UTM tag. Follow the link without UTM tags and you will not see this block. For convenience of testing in this example, cookies are not recorded.
Follow the link with the UTM tag and another block will be shown in this place:
go to the link
In this article, I showed only the simplest example of how much my fantasy was enough. If you have another task, have questions or requests, write your comment below.

Artificial Life Software Review
There seems to be some useful artificial life software. Artificial life software is useful because they include neural network, genetic and artificial world components.
Wikipedia separates artificial life software into four categories: program-based, module-based, parameter-based and neural net-based.
Program-based artificial life uses DNA which resembles computer programs more than biological DNA.
Module-based artificial life software uses modules to specify creature behaviour. The focus is more on user creation and less on evolution.
Parameter-based artificial life software uses parameters to modify pre-defined creature behaviour. It is the parameters which mutate over time.
Neural net-based artificial software have creatures that have neural networks for learning.
Program based artificial life software includes:
Avida is similar to Tierra which simultes an evolutionary system in which computer programs compete for computer resources. In Tierra, organisms share and compete for one "brain." In Avida, each organism has its own brain.
breve looks interesting because it has a 3D world and physics. It handles agent communication, 3D space representation, graphical rendering and physical simulation.
Does it have neural network and genetic components? It looks like breve does have a genetic component but it seems that if it focuses more as a virtual world and requires neural network components from other software libraries.
A page on breve's homepage references a few other popular agent environments:
Swarm somehow does not seem to be what I am looking for.
Mason looks quite powerful and it seems like I can mould it into what I am looking for. I do prefer real time grapics. I don't think it has neural network and genetic algorithm components.
NetLogo seems to have support for neural networks and genetic algorithms but I feel a bit unsure about it.
Darwinbots, has simple graphics. I think I have been spoiled by the other software packages.
 - [N] Neural network components? It has a finite state machine like system.
 - [Y] Genetic algorithm components? Life-like forces shape evolution.
 - [N] 3D environment? It has a 2D world.
Evolve 4.0
 - [N] Neural network components?
 - [?] Genetic algorithm components? It simulates things a cellular level.
Framsticks looks good. Can Framsticks simulate communication?
Micropond is similar to Nanopond. Nanopond in turm is similar to Avida and Tierra.
Tierra is kind of like Avida.
Module-based artificial life software includes:
 - TechnoSphere
TechnoSphere looks interesting but I feel that it lacks the control I need. I need to be able to program neural networks and communication systems. It looks like TechnoSphere is more about letting users pick and choose physical
Parameter-based artificial life software includes:
 - Kyresoo Plants
Kyresoo Plants does not seem to be what I am looking for. From an online encylopedia, "Most Alife software such as Avida, Darwinbots, Polyworld, focus on the collective behaviour of a large number of simulated organisms. Kyresoo Plants focuses on the collective behaviour of multiple cells in a single organism."
The same page mentions something about the biomorph model describe by Richard Dawkins in the book, "The Blind Watchmaker." This is interesting because of I am a fan of Dawkins' work.
Neural network based artificial life software includes:
Creatures looks interesting but it is a commercial product and I don't know how much I can extend it. There seems to some developer support. It doesn't look like it allows me to get to the nitty gritty such as setting up actual neural networks and communication pathways.
Noble Ape looks very interesting. It holds similar ideals as this project does. Is it easy to set up a small number of creatures with neural networks in Noble Ape?
Polyworld looks almost exactly like what I am looking for. It has neural network components, genetic algorithm components and a world. It looks kind of old.
NationMaster, an online encyclopedia also has a number of other artificial life software.
Program Based
Physis seems to be at a cellular level and seems similar to Tierra.
Archis seems similar to Nanopond.
Neural Net Based
NERO looks quite interesting. It simulates teams of agents engaged in battle. It has neural network components but no genetic algorithm components although the environment itself provided evolutionary pressures. Unfortunately it seems like it is not open source. According to the AI algorithms are open source but the rest of the package is not open source because it uses a commercial game engine.
Okay, so after all that, the following is my short list for artificial life environments:
 - breve
 - Framsticks
 - Noble Ape
 - Polyworld

Pixels in the region
Pixels are determined to be in the region (and weighted) according to the following rules, applied in the specified scale and projection:
 - Unweighted reducers (e.g. ee.Reducer.count() or ee.Reducer.mean().unweighted()): pixels are included if their centroid is in the region and the image's mask is non-zero.
 - Weighted reducers (e.g. ee.Reducer.mean()): pixels are included if at least (approximately) 0.5% of the pixel is in the region and the image's mask is non-zero; their weight is the minimum of the image's mask and the (approximate) fraction of the pixel covered by the region.


What is PhD life like in the Netherlands?
Eva Lantsoght
Eva Lantsoght
7 Nov '19
Some time ago, a reader asked me: "Eva, what are the opportunities for doing a PhD in the Netherlands, and how is it different from a PhD in other parts of the world?" That's an excellent question, and perhaps you are not aware of the differences between the PhD in the Netherlands and in other parts of the world.
On the internet and in the academic literature on doctoral studies, we mostly find references to PhD programs in the UK and the USA, with the odd reference to Australia or New Zealand. Few references and blogs deal with the PhD in continental Europa.
Since I did my PhD in the Netherlands and my husband in the USA, we often discussed how very different the programs are. If you are contemplating applying to a PhD position in the Netherlands, it may be good to know what is like, and how it is different from the many descriptions you find online about PhD life in the UK and USA.
Here are a few things that are different in the Netherlands:
1. You are a university employee
In the Netherlands, you either are hired as a university employee (one year contract first and then extension, or four years' contract) or as a scholarship student. Getting hired as a university employee is quite common, and is the typical arrangement when your PhD is funded by a research project. There are many advantages to being hired as a university employee, which include social security, employee protection, building up retirement savings etc. It also means of course that you have to pay taxes on your salary.
2. You apply to a project
The common path in the Netherlands is to apply to an advertised PhD position. This position will only be advertised when the project is already funded. In other words, part of the research and deliverables are already defined before you start. The proposal is already approved and funded. This approach is different from programs where you apply to work with a certain professor, and then propose your project, and defend your proposal.
3. Coursework is very limited
Traditionally, the PhD program in the Netherlands is a research-only program. In recent years, some universities have started doctoral schools, which require you to take a number of courses. Some of these courses are related to research skills, whereas other courses are related to your field of study. However, a number of these courses can be organized as intensive courses or summer schools. As such, your day to day life will still be mostly focused on your research.
4. People tend to treat their PhD like a job
You will see that in the Netherlands, PhD candidates tend to treat their PhD like a job with relatively steady hours. It may also be a requirement that you are in your office between certain blocks of time. University buildings tend to have opening and closing hours. Working around the clock or during odd hours is thus much less common than in the US.
5. Defense after publication of the thesis
In the Netherlands, your committee will approve your thesis, then you send your thesis for publication and printing, and at the very end you will have your defense and graduation ceremony in one event. In the USA and the UK, you finalize your thesis after the defense instead. So, in the Netherlands, the defense is much more of a ceremony and rite of passage (and a very formal one indeed) than in other parts of the world.
6. Your working environment may be partially Dutch-spoken
While the lingua franca of academia in the Netherlands is English, and you will most likely publish your thesis in English and give all academic presentations in English, part of your working environment will be in the Dutch language. When you have funding from industry or the government, it can be to your advantage to speak Dutch if you are the only person during meetings who does not speak the language. Try to learn the language early on, so that you can work more easily with partners outside of academia.
About Eva Lantsoght
Eva started writing about doing a PhD while studying concrete structures at TU Delft and since then blogs about the non-scientific skills you need during a PhD and life as a PhD.

HRMCAR › OECD Core Competencies
The OECD Competency framework
The OECD Competency framework comprises core competencies which are presented in three clusters. The first cluster groups the delivery related competencies, the second has interpersonal competencies and the third relates to strategic competencies.
What are core competencies?
Core Competencies can be defined as personal attributes or underlining characteristics, which combined with technical or professional skills, enable the delivery of a role/job. Competencies state the expected areas and levels of performance, tell us what is valued and rewarded. The Core Competencies do not define our technical roles and accountabilities, nor does it include the technical skills necessary to do our jobs.


The Building Permit in Romania
The Building Authorization System in Romania
Romania has one of the most complicated and time-consuming building permit procedures within the EU. It was ranked as the 50th in the world. The system is also rigged by some corruption phenomena. You should not be concerned about corruption, but they might interfere[1] with your project.
To obtain a Building Permit (Autorizație de Construire), there are two legal paths, determined not by choice, but by local zoning code (Regulament Local de Urbanism).
The two paths are direct and indirect authorization. They are similar to some extent, except that the indirect includes an Urbanism Project called either PUD (Plan Urbanism de Detaliu) or PUZ (Plan Urbanistic Zonal).
The steps are the following, for the DIRECT AUTHORIZATION:
 1. Urban Certificate (Certificat de Urbanism) – issued by the local city hall (Primărie), sometimes with verification by the County Hall (Consiliul Județean)
It states what the zoning code is (Regulament Local de Urbanism) considering that within an area, the rules might differ.
It also states the required pre-approvals (aviz, avize or acord, acorduri) the project should acquire, these being of two types:
 1. Pre-approvals:
 1. Pre-approvals (avize) related to the land:
 1. Environmental Agency preliminary evaluation of impact (followed or not by further steps). Usually, the notification to the Agency results in a Notification Classification (Clasificarea Notificării). It means there are no further steps[2]. For some investment types, as industrial, or even for residential that requires infrastructure, this can develop into new steps. In this case, there will also be needed an Environmental Accord (Acord de Mediu). To get an Environmental Accord, other pre-approvals might be needed, like a pre-approval from the Water and Forest Agency (if the project includes water pits, deforestation, and such).
 2. Pre-approvals from utility companies such as Electrical Company, Water Company, Gas Company, Phone Company, etc. These basically state that they are not bothered by your project, as your project does not affect their infrastructure (as gas pipes, water pipes, high voltage electrical lines, and their protection zones. They do not include the rights to get service-pipe to their infrastructure, nor guarantee they can provide you the proper amount of gas, electricity, etc. For these works there are different procedures, that let you know from what point you can make extensions to the gas pipes, if (most likely sure) you have to build your own electrical transformer, if and where you can connect your sewerage pipes to the zone sewerage system if one exists.
 - Pre-approvals from other different agencies, such as Waters and Forrest Agency for proximity with water bodies or forests and so on.
 1. Pre-approvals from infrastructure companies and/or agencies as National Roads Agency, Railroad Company, Army (in case of the proximity of military bases or installations), SRI (one of our seven intelligence agencies for whatever buried purposes they might have). The National Roads Agency issues a mixed approval as they both check if your project doesn't interfere with roads' safety building exclusion zone and the conformity of your roads junction with the national roads. This might include a special project to design the junction if it will require traffic lights, traffic roundabouts, viaducts, or whatever it will be needed.
 2. I might forget some possible pre-approvals. Nevertheless, not all these are required for all projects
 3. Pre-approvals related to the designed buildings and/or Masterplan:
 1. Local Health Agency (by a very new law modification, this might not be needed anymore, but…)
 2. State Construction Inspectorate (ISC Inspectoratul de Stat în Construcții) approval (Acord ISC) (usually only for interventions on or near existing buildings, but sometimes for larger projects too)
 - Fire Department Pre-approval (It usually is not required for small residential units, but considering you are developing basically a new little town, it might be possible). You might have to provide a local fire extinguishing water infrastructure. A further discussion should be made on fire safety regulations in Romania.
 1. Historical Comity for Historical Sites, alterations of Historical Monuments, and/or for buildings within the protection range of Historical Monuments.
 2. Other pre-approvals might be required that are a mix of land and project approvals, such as Air Traffic Agency if you are in the proximity of an airport and they might have to compare the building's height to the flight aisle conditions.
 3. County Circulation Comity approvals – checking the required parking plots, junctions with national and/or local roads, and so on.
 - Traffic Police approval might be required. Unfortunately, at least in Bucharest, they do not issue such approval (aviz)
 1. Building Permit – AC (Autorizație de construire). It is issued by the local city hall.
I know, I know, what could be more complicated than the Direct Authorization?
The steps are the same, but:
 1. CU
 2. Pre-approvals for PUZ or PUD, including most of the land-related pre-approvals. Attention! The pre-approvals for the PUZ or PUD sometimes are not allowed to be used during the further steps, some new ones might be issued for the construction phase, aka the direct authorization.
 1. The first step on Environmental Agency Approval
 3. Opportunity study and Public consultation.
 4. CTUAT pre-approval for PUD/PUZ (Aviz CTUAT – Comisia Tehnică de Urbanism și Amenajarea Teritoriului) Urban and Territory Planning Comity.
 5. Further Public Consultation
 6. City or County Hall Chief-Architect approval (usually a formality after CTUAT Approval has been issued)
 7. Local and/or County Council Approval. The Local Council is the local legislative body that approved also the Local Zoning Code (Regulamentul Local de Urbanism). As the PUZ and PUD are basically derogations and/or amendments to the Local Zoning Cod, this is the only body allowed to modify it.
 8. Pre-approvals as stated on point 2. Of the Direct Authorization
 9. AC – Building Permit
After the Building Permit is issued, the investor should notify the City Hall on the date of construction start.
The Builder or the Investor notifies the ISC (Construction State Inspectorate) on the construction start date and submits the Determining Phases Program[3].
Modifications During Construction
The Building Permit has a real A4 Authorization and a set of plans including the masterplan, architectural plans, facades, sections, parts of the Structural Design as Foundations Plans and Details, Schematic Drawings of MEP and Electrical designs, Technical Reports (Memorii Tehnice) by each specialty stamped as „Vizat spre Neschimbare[4]" by the Chief-Architect of the City Hall.
Any modifications of the Building Permit Design that might affect the building during the construction phase, changing the aspect, the solution, etc should follow a specific procedure.
„DS – Dispoziție de Șantier" (Site Order) is a document issued by the architect, the structural engineer, the MEP or electrical engineers that indicates what the changes are related to the approved plans and what is the reason for the changes, or any changes to the construction documents.
The DS can consist of a written part (let's say the Structural Engineer decides to use a C20/25 concrete instead of C16/20) for no matter what reason.
The DS can include some details. If the Detail provided does not change the overall design, the DS is used only on-site and is opposable only to the Builder. If the Detail provided includes modifications to the approved designed within the Building Permit, it should also be submitted to the City Hall.
The DS can include revisions of initial plans, either containing small or large modifications. Such DS can change some, or even all the plans submitted to the Building Permit.
The DS can include more than one person to issue it. Let's say the architect change the position of a door inside the house, then the DS is also signed by the Structural Engineer if the modification does not alter the structural integrity of the building.
If the DS issued by the architect is relevant to the structural integrity the Structural Engineer will also issue his/her own DS including the needed changes (reinforcements geometry size and positions and so on).
The changes that affect the structure might require also an Expert Technical Report issued by a Structural Technical Expert[5].
After a DS was issued it has to be submitted to the City Hall. The Chief-Architect sets if the modification is allowed within the Building Permit, or if the changes have to be the subject of a new Building Permit.
If no new Building Permit is required, the Chief-Architect signs and stamps the plans with „Vizat spre neschimbare", No Further Changes Allowed.
There is no limit on how many DSs the design team can issue, but all of them should be subject to the City Hall procedures described.
All DSs have to also be signed by the Builder, the Site Director (as the Investor's technical representative), and also by the Owner.
A DS if contains modifications that are not


text: Application of using rare earth salts with acid dyes for dyeing wool fabrics have been investigated. The rare earth salts used include neodymium chloride, samarium oxide and gadolinium oxide; and acid dyes used are C.I. Acid Red 114, C.I. Acid Yellow 42 and C.I. Acid Blue 113. The results of these experiments exhibit that the addition of rare earth salts does lower the dyeing temperature of wool slightly, and the addition of neodymium chloride achieved the better result. The result of mixing different rare earth salts is not very distinct, although the mixture of neodymium chloride and gadolinium oxide in the ratio 8:2 has the best effect. Moreover, the addition of rare earth salts has no great impact on the tenacity of dyed fabrics. Among the color range of dyed fabrics, Red 114 has better color strength. Furthermore, the washing fastness of fabrics can be up to grade 4-5 in general, while its dry rubbing fastness can be up to grade 4-5 and its wet rubbing fastness can be up to grade 3-4.

Onos - oh'noss - n. - A Greek concept of rational worry; represented by Homer's Odyssey in Athena, a Greek Goddess, and many Greek heroes in other traditional works, it is considered a positive attribute.
Romans considered "onos" a negative attribute, like Odysseus' intelligence, and it became transmuted into the less-positive "onus," or "burden."
Athena's onos was manifested in her fear of Poseidon's threat to Odysseus' homecoming.

Design considerations when integrating smoke and fire curtains into a building
Fire curtains and smoke curtains are very commonly mixed up and the terminology around them is often interchangeably and wrongly used. This white paper examines what a smoke curtain is and what a fire curtain is, explaining how they are designed, the standards and test regimes that apply to each, and how they are each expected to be applied.
This white paper covers:
 - What are smoke curtains and fire curtains and what are the key differences between them
 - The standards which each type of system has to comply with
 - The design aspects to consider when integrating these systems into a building
 - Installation, use, testing and maintenance.

noting that, despite appearances, \theta = 0 is not a solution (as can be checked from the original form of this equality, unless x and y are infinite, in which case the expression is clearly non-negative, as we show towards the end of this post). This leaves us with \theta = \pi and
\cos(\theta) (\tan^{-2}(\theta/2)-xy) = \sin(\theta)(x+y-2\tan^{-1}(\theta/2)),
as candidates for where the minimum may be. A quick check shows that:
F(\pi,x,y) = 4 \int_0^x \frac{s^4}{(1+s^2)^2} ds+4 \int_0^y \frac{s^4}{(1+s^2)^2} ds \ge 0,
since x and y are non-negative. The following obvious substitution becomes our greatest ally for the rest of the proof:
x= \alpha \tan^{-1}(\theta/2), \, y = \beta \tan^{-1}(\theta/2).
Substituting the above in the remaining condition for \partial_\theta F(\theta,x,y) = 0, and using again that \tan^{-1}(\theta/2) = (1+\cos\theta)/\sin\theta, we get:
\cos\theta (1-\alpha\beta) = (1-\cos\theta) ((\alpha-1) + (\beta-1)),
which can be further simplified to (if you are paying attention to minus signs and don't waste a week on a wild-goose chase like I did):
\cos\theta = \frac{1}{1-\beta}+\frac{1}{1-\alpha}.
As Greg loves to say, we are finally cooking with gas. Note that the expression is symmetric in \alpha and \beta, which should be obvious from the symmetry of F(\theta,x,y) in x and y. That observation will come in handy when we take derivatives with respect to x and y now. Factoring (\cos\theta)^3 -3\cos\theta -2 = - (1+\cos\theta)^2(2-\cos\theta), we get:
\partial_x F(\theta,x,y) = 0 \implies \sin^3(\theta) y + 4\frac{x^4}{(1+x^2)^2} = (1+\cos\theta)^2 + \sin^2\theta (1+\cos\theta).
Substituting x and y with \alpha \tan^{-1}(\theta/2), \beta \tan^{-1}(\theta/2), respectively and using the identities \tan^{-1}(\theta/2) = (1+\cos\theta)/\sin\theta and \tan^{-2}(\theta/2) = (1+\cos\theta)/(1-\cos\theta), the above expression simplifies significantly to the following expression:
4\alpha^4 =\left((\alpha^2-1)\cos\theta+\alpha^2+1\right)^2 \left(1 + (1-\beta)(1-\cos\theta)\right).
Using \cos\theta = \frac{1}{1-\beta}+\frac{1}{1-\alpha}, which we derived earlier by looking at the extrema of F(\theta,x,y) with respect to \theta, and noting that the global minimum would have to be an extremum with respect to all three variables, we get:
4\alpha^4 (1-\beta) = \alpha (\alpha-1) (1+\alpha + \alpha(1-\beta))^2,
where we used 1 + (1-\beta)(1-\cos\theta) = \alpha (1-\beta) (\alpha-1)^{-1} and
(\alpha^2-1)\cos\theta+\alpha^2+1 = (\alpha+1)((\alpha-1)\cos\theta+1)+\alpha(\alpha-1) = \\ (\alpha-1)(1-\beta)^{-1} (2\alpha + 1-\alpha\beta).
We may assume, without loss of generality, that x \ge y. If \alpha = 0, then \alpha = \beta = 0, which leads to the contradiction \cos\theta = 2, unless the other condition, \theta = \pi, holds, which leads to F(\pi,0,0) = 0. Dividing through by \alpha and re-writing 4\alpha^3(1-\beta) = 4\alpha(1+\alpha)(\alpha-1)(1-\beta) + 4\alpha(1-\beta), yields:
4\alpha (1-\beta) = (\alpha-1) (1+\alpha - \alpha(1-\beta))^2 = (\alpha-1)(1+\alpha\beta)^2,
which can be further modified to:
4\alpha +(1-\alpha\beta)^2 = \alpha (1+\alpha\beta)^2,
and, similarly for \beta (due to symmetry):
4\beta +(1-\alpha\beta)^2 = \beta (1+\alpha\beta)^2.
Subtracting the two equations from each other, we get:
4(\alpha-\beta) = (\alpha-\beta)(1+\alpha\beta)^2,
which implies that \alpha = \beta and/or \alpha\beta =1. The first leads to 4\alpha (1-\alpha) = (\alpha-1)(1+\alpha^2)^2, which immediately implies \alpha = 1 = \beta (since the left and right side of the equality have opposite signs otherwise). The second one implies that either \alpha+\beta =2, or \cos\theta =1, which follows from the earlier equation \cos\theta (1-\alpha\beta) = (1-\cos\theta) ((\alpha-1) + (\beta-1)). If \alpha+\beta =2 and 1 = \alpha\beta, it is easy to see that \alpha=\beta=1 is the only solution by expanding (\sqrt{\alpha}-\sqrt{\beta})^2=0. If, on the other hand, \cos\theta = 1, then looking at the original form of F(\theta,x,y), we see that F(0,x,y) = 6\pi - 6\arctan(x) +2x/(1+x^2) -6\arctan(y) +2y/(1+y^2) \ge 0, since x,y \ge 0 \implies \arctan(x)+\arctan(y) \le \pi.
And that concludes the proof, since the only cases for which all three conditions are met lead to \alpha = \beta = 1 and, hence, x=y=\tan^{-1}(\theta/2). The minimum of F(\theta, x,y) at these values is always zero. That's right, all this work to end up with "nothing". But, at least, the last four weeks have been anything but dull.
Update: Greg offered Lemma 7.4 from the same paper as another challenge (the sines, cosines and tangents are now transformed into hyperbolic trigonometric functions, with a few other changes, mostly in signs, thrown in there). This is a more hardcore-looking inequality, but the proof turns out to follow the steps of Lemma 7.1 almost identically. In particular, all the conditions for extrema are exactly the same, with the only difference being that cosine becomes hyperbolic cosine. It is an awesome exercise in calculus to check this for yourself. Do it. Unless you have something better to do.

 2. Let me say that the mathematics beyond "the most well-known trigonometric identity of all time" is mostly intractable to me but still this was an enjoyable, very readable and engaging narrative.
 Thanks for sharing your story – it highlights the human aspect in problem solving.
 - Thanks Terry. Indeed, the math used here may seem intractable to most non-practicing mathematicians, but nothing is beyond high school level algebra, trigonometry and basic calculus. The hard part is the "how did he know to do that substitution, or re-write the expression in that other form"? The cases where this was not obvious in my writing are the cases that required two weeks of looking at trigonometric identities until they were my best friends.
 - What a rude and spiteful comment: Spyridon emphatically says he worked out this problem just for fun, with no pretensions to grandeur. You know what the mark of a small, pathetic mind is? Trivializing someone else's work solely in order to self-aggrandize.
 - It's not that bad. Perhaps Jack doesn't have a lot of experience reading about the weeks often spent "barking up the wrong tree" in research, and just wanted to apprise us of another interesting anecdote.

This module provides a quick review of dynamic programming, but the student is assumed to have seen it before. The parallel programming environment is NVIDIA's CUDA environment for graphics cards (GPGPU - general purpose graphics processing units). The CUDA environment simultaneously operates with a fast shared memory and a much slower global memory, and thus has aspects of shared-memory parallel computing and distributed computing. Specifics for programming in CUDA are included where appropriate, but the reader is also referred to the NVIDIA CUDA C Programming Guide, and the CUDA API Reference Manual.
Upon completion of this module, students should be able to:

What Are My Degree Options at CCC?
Coffeyville Community College offers four different associate degree options, and choosing the option that is best for you can be confusing. Below are explanations of the intended purpose of each degree option.
A.A. Degree (Associate in Arts)
This is the degree option a majority of students at CCC choose. This is the degree option designed for students who wish to transfer to a four-year institution after graduation from CCC, or for students who wish to one day enroll into a bachelor's degree program. This degree fulfills most of the general education requirements at a four-year school and will grant you junior status when you transfer, a big deal at enrollment time. So, if you plan to work on a bachelor's degree at some point in your life, this is the degree option for you.
A.S. Degree (Associate in Science)
This transfer degree serves the same purpose as the A.A. degree, but is intended for students who plan to major in a math or science field at a four-year school. So, if you plan to major in a program at a four-year school that requires a lot of math and science, this degree option is intended for you.
A.G.S. Degree (Associate in General Studies)
This degree option has a major difference between the A.A. degree – this one only requires Intermediate Algebra to graduate from CCC instead of College Algebra. It can be used for transfer, but be aware that at some point you will likely need to take College Algebra or higher level math course to earn a bachelor's degree. It is recommended you choose an A.A. or A.S. degree option if you plan to ever work on a bachelor's degree later.
A.A.S. Degree (Associate in Applied Science)
This is the degree option that many students in a technical program will choose. Students choosing this option will complete a technical program such as welding, electrical, automotive, etc. In addition to completing a technical program curriculum, students also complete 16 general education hours to complete requirements for the A.A.S. degree. This is a degree option utilized mostly by students at the Coffeyville Technical Campus and the Columbus Technical Campus.

Radiology is a crucial and intricate field of medicine that plays a pivotal role in accurate diagnosis and patient care. As a radiologist, your expertise in interpreting medical images is indispensable. However, like any medical profession, radiology is not without its risks. That's where malpractice insurance comes into play.
1. What specific risks are associated with radiology practice that malpractice insurance should cover?
Malpractice insurance for radiologists should cover specific risks such as errors in image interpretation, procedural complications, failure to recommend appropriate tests, failure to communicate results in a timely manner, and harm due to radiation exposure.
2. Does the malpractice insurance cover interventional radiology procedures?
While most malpractice insurance plans should cover interventional radiology, it is essential to confirm this with your insurance provider, as these procedures are often riskier and could require additional coverage.
3. How is the coverage limit determined for radiologists?
Coverage limits for radiologists can depend on several factors, including the type and volume of procedures performed, the risk profile of the practice (e.g., whether you're involved in interventional radiology), and the state or region's litigation history.
4. Are teleradiology services covered?
Most modern medical malpractice insurance policies cover teleradiology services. However, it's important to confirm this with your provider, as there may be specific stipulations or limitations, especially if you are providing services across state lines or internationally.
5. Does the policy cover me for lawsuits related to radiation exposure?
Most comprehensive malpractice insurance policies should cover lawsuits related to radiation exposure. However, there may be exceptions, limits, or specific conditions, so it's essential to clarify this with your provider.
6. What does 'consent to settle' mean in my policy?
'Consent to settle' means that the insurance company cannot settle a claim without your agreement. This clause can be important for healthcare providers, including radiologists, who may be concerned about their reputation and professional record.
7. Is coverage provided for cases related to incorrect interpretation of images?
Yes, malpractice insurance typically covers cases related to incorrect interpretation of images, as this falls under the standard professional liability that a radiologist would be expected to have.
8. What happens if I switch to a different sub-specialty within radiology?
If you switch to a different sub-specialty within radiology, you should inform your insurance provider as it may impact your coverage. Some specialties may carry different levels of risk and therefore require different coverage levels.
9. Does the insurance cover legal defense costs?
Typically, malpractice insurance policies do cover legal defense costs, which can include lawyer fees, court costs, and even settlement or judgment costs. However, policies can vary, and it's essential to confirm this with your provider.
10. What is "tail" coverage, and do I need it?
Tail coverage, or Extended Reporting Period (ERP) coverage, protects you from claims made after your policy ends but stems from care provided while the policy was active. Depending on your situation and the terms of your policy, tail coverage may be advisable, as claims can sometimes be filed months or even years after an incident.
11. Is coverage provided for the use of AI diagnostic tools?
As AI diagnostic tools become more prevalent in radiology, many insurance providers are adapting their policies to include related risks. However, this isn't standard across the board, so it's crucial to ask your provider about this coverage.
Remember to always consult with an insurance professional or legal advisor to understand the nuances of your specific policy and coverage.

Create a dashboard with Google Sheets
Learn how to create a free dashboard with Google Sheets
Zero can import data from any source can build charts, tables & forms with it. In this blog post we will see how to import data from a Google Sheet into Zero. We will be using Zero's free plan so you can reproduce everything for free.
In this example we are going to see 3 different use cases, from that you can go on and build something which fits your use case exactly.
To start create a free account at and login. Once you have an account create a new board and open it.
Example 1: Dynamic data from Google Finance
This is an example of how we use Google Finance to create a board with the market cap of a few companies:
Create a spreadsheet with the following format:
CompanyMarket Cap
You can of course add as many companies as you want and use any type of metric other than market cap.
This is the spreadsheet we will use in this example:
We will use Zero's free Google Sheet to JSON Converter API to fetch the data. Make sure that your spreadsheet is public.
Let's create a new chart block:
Inside your Zero board click on new chart
In the script section paste the following code:
// Replace your URL below
const spreadsheet_url = ""
const {data} = await api.get("", {params:{format:3, url:spreadsheet_url}})
return data
Since we want the companies to be in the X Axis we will add Company in the X Axis input. As chart type we select Bar.
This will produce a chart like the one below:
Below that we want a table with the values. So once we saved this block we can click on new table and paste the exact code from above. This will display a nice table.
The two blocks with a small gap between them. On the first block (the chart) click on the top right three dotted icon and then click on Remove Gap. This will remove the gap below and nicely link the two blocks.
That's it!
Now you have a beautiful dashboard which works great on mobile with data fetched directly from Google Finance!
Example 2. Data from Facebook Lead Ads
If you run facebook lead ads you might want to have a dashboards where you see new leads. Let's build that with a little help from Zapier.
Signup to Zapier and use this automation - Once setup your lead will go directly to your Google Sheets.
From there you can follow the example above and do almost anything. These are a few examples:
With a spreadsheet like this:
LeadProcessedDate Added
 1. Display a table with a form to process leads: You could display a table with every lead and in the edit row script send data back to your backend once the lead has been processed.
 const lead =
 const processed =
 if (!["TRUE", "FALSE"].includes(processed)){
 throw new Error ("Processed must be TRUE or FALSE")
 // await // Post your data to your backend
 return '${lead} processed:${processed}'
 2. Group the leads date and create a chart with the total number of leads in one day.
 Something like this:
 const spreadsheet_url = ""
 const temp = []
 data.forEach(lead => {
 const date = lead['Date Added']
 existing_index = temp.findIndex(l => === date)
 if (existing_index > -1) {
 new_value = temp[existing_index].value += 1
 temp[existing_index] = {date:date, value:new_value}
 } else {
 temp.push({date:date, value:1})
 return temp
With Zero you can build any sort of interactive dashboards directly from Google Sheets. It's free to use.

Campus: San Diego State University -- February 9, 2005
SDSU, Mexican University Complete Comprehensive Tijuana
River Watershed Atlas
Researchers at San Diego State University, along with partners around San Diego
and at El Colegio de la Frontera Norte (COLEF) in Mexico, have completed the most
comprehensive set of geographical data ever assembled about the Tijuana River
watershed, a crucial step toward successful long-term planning and management
for the fast-growing binational area.
The Tijuana River Watershed Atlas, in development for nearly a decade, includes
approximately 80 photographs, maps, and text in English and Spanish. It captures
much of the diversity and complexity of the watershed, a 1,750-square-mile drainage
basin that stretches from the Pacific Ocean at the Tijuana River Estuary north to
Mount Laguna and southeast into remote mountains and valleys located well inside
Richard Wright, professor of geography at SDSU and Rafael Vela of COLEF, general
editors of the project, said the new atlas is an important breakthrough because
it presents the first unified view of the watershed as seen by scholars on both
sides of the border.
"For the first time, policymakers and planners from the United States and Mexico
can work from a common set of data," Wright said. "That has been one of the
impediments to binational cooperation over the watershed in the past. If you're
not working with the same information, how can you productively discuss your
similarities and differences of opinion?"
The atlas, a boxed set of dozens of maps, photos and text each suitable for display
on a wall, includes many types of data, ranging from topography and climate
information to human population and land use patterns.
In addition to serving as a policy and planning tool, Wright said the atlas also
serves as an effective educational aid for demonstrating how the two nations are
intertwined by the watershed's systems and landscape. More than 200 copies of the
atlas are being provided to the San Diego Natural History Museum for use in the
PROBEA project, a binational environmental teacher education program. Some
copies of the atlas will be available to other educational agencies at no cost.
Compiling the atlas was a challenging endeavor at times, Wright said. The
researchers had to arrange for National Oceanographic and Atmospheric Administration
(NOAA) aircraft to fly over Mexican airspace to take aerial photographs of the
areas of the watershed south of the border. SDSU partnered with the San Diego
Association of Governments to obtain needed satellite imagery. Common classification
systems had to be created in English and Spanish for some data, such as land use.
In some cases, maps required extensive field work and many months of labor to
For more information or to obtain copies of the atlas, call _PHONE_ or

research and production of the Tijuana River Watershed Atlas was provided by the
Southwest Consortium for Environmental Research and Policy, the U.S. Environmental
Protection Agency, NOAA, and SDSU's Institute for Regional Studies of the
Californias (IRSC) and Department of Geography Center for Earth Systems Analysis
Research. Harry Johnson of the Department of Geography was the chief cartographer
for the atlas and Paul Ganster, director of IRSC, was the principal text editor.

Description of the habitat
Lowland hay meadows are very blossomy and species-rich, meadow communities on dry to wet-dry, mostly fresh sites. Characteristically, they have a multitude of blooming herbs and numerous low, middle and high grasses, making these meadows look diverse and colourful. Corresponding to the local conditions and the cultivating methods, there is an abundance of forms of the habitat. The numerous low-nutrient indicators are characteristic for lowland hay meadows. Additionally, one often finds endangered plant species.
Situation and endangerment of the habitat in the project area
Lowland hay meadows occur nationwide on nutrient-low sites which are used respectively. The main transmission area is in the southwest of Luxembourg. The main impairment lies within the intensifying agriculture. Fertilisation, early and abundant cuts, high livestock density and drainage lead to the loss of the habitat. Another problem is caused by the loss of surface area through construction.
Provisions within the project
Purchase of 30 ha. Extensification of the use and, if needed, renaturation of the meadows and resettlement of highly endangered plant species.

Deborah sheds light on the truths in this inspiring book in the Bible. I love that she showed the connection between Ruth and Boaz and Christ and the church. Even though I've studied Ruth before, Deborah pointed out several details that I hadn't known. It's amazing how God speaks through His children. Deborah has a loving, humble heart for the Lord. You can see her heart throughout the book. I am so happy for her first release. I look forward to more books from Deborah in the future.
– Amanda Beth, author, You Can Have a Happy Family
I appreciated the attention to detail, the explanation of the Hebrew customs, and making the story relevant to my life so I could relate to Naomi and Ruth. Each chapter ends with a rendering of the passage in the King James Translation with a short, heart-felt prayer and study questions for further reflection.
I also appreciated that the book is Biblical sound and concise and written in a style that is easy to understand.The Book of Ruth – a Story of Love and Redemption, would serve as a helpful study guide for women of all ages.

Author Deborah Bateman does a great job of explaining the role of the kinsman-redeemer in reclaiming the family of one who has died. She also explains the relationships that are key in the story: 1) Ruth who loves her mother-in-law so much that she leaves her own family and homeland to care for Naomi in Bethlehem; 2) Boaz who marries Ruth as the kinsman-redeemer; 3) God who honors the lineage of Boaz & Ruth by becoming the ancestors of King David and eventually the Lord Jesus Christ.
The Book of Ruth by Bateman is a tender and valuable study for a week of looking into your own family relationships as well as your relationship with God.
– Diane Tatum, author, Gold Earrings
The author of this handy, easy-to-read volume, Deborah Bateman, has captured the essence of this love in her first publication, The Book of Ruth-A Story of Love and Redemption.
Bateman begins each chapter with a simple expository, followed by the Scripture verses to which it refers. Writing it thus makes it easy for the reader to remain in the book and not have to move from book to Bible. This format also makes it easy to follow the Biblical record and use it as a daily Bible reading. The prayer and thought for the day, which concludes the chapter, enabled me to reinforce what I had just read.

What is 1 Mod 50? (1 % 50)
In this article we're going to look at what 1 mod 50 means and how we can calculate that. This type of divisibility operation is called mod, modulo or modulus and you can often see the symbol % used as well (i.e. 1 % 50)
Modulo is the mathematical operation which lets you find the remainder when dividing two numbers like 1 and 50 together. When are say "what is 1 % 50?" we are asking "when I divide 1 by 50, what is the remainder?"
 - The first number, 1, is called the dividend
 - The second number, 50, is called the divisor
 - When you divide 1 by 50, the answer is called the quotient
To calculate 1 mod 50 we first need to divide 1 by 50 to get the quotient:
1 / 50 = 0.02
Now we have the quotient, we take the whole part of it (0) and multiply it by the divisor (50):
0 x 50 = 0
1 - 0 = 1
Therefore, the final answer is:
1 mod 50 = 1
We could also calculate this using a different method. To use this method, list out all of the multiples of the divisor (50) and find the one that is equal to or less than the dividend (1).
The multiples of 50 are: 0, 50, 100, 150, and so on.
As we look at those multiples of 50 we can see that the highest number that is less than or equal to the dividend (1) is 0.
1 - 0 = 1
1 mod 50 = 1

Gifts and Celebratory Events for Employees and Nonemployees
Policy Statement
Harvard units may occasionally spend modest amounts from appropriate funding sources to recognize employees or nonemployees under certain circumstances.
Allowable employee recognition may take the form of celebratory events or gifts for the following occasions:
 - Work-related achievement
 - Employee morale-building events
 - Sympathy upon the death or serious illness of an employee or employee's immediate family member
Allowable nonemployee recognition must be for a legitimate Harvard business purpose and should be motivated by detached or disinterested generosity or respect, admiration, charity or like sentiment. Gifts to nonemployees may not be given in lieu of payment for services or as a quid pro quo.
Units must use prudent judgment and also follow the IRS rules outlined below. University funds may not be spent in recognition of personal events or achievements unrelated to work, such as birthdays, weddings, baby showers, housewarming, etc., or for gifts in recognition of holidays rather than work-related achievement.
Employee Gifts and Celebratory Events Policy Table of Contents
 1. Gift must be for an allowable reason
 2. Celebratory or employee morale building events
 3. Gifts to nonemployees
 4. General information regarding funding source and object codes
 5. Gifts given to Harvard personnel from third parties.

Genes that are active are located mainly in the central region of the nucleus, while inactive genes are at the periphery. But scientists have had no way to track chromosome movement inside the nucleus or to determine whether the location of the chromosomes was the result of random diffusion or if they are moved around by molecular motors.
In a study published in the April 17 issue of Current Biology, UIC and UIUC researchers show that chromosomes in the cell nucleus are capable of directed, long-range movement that depends on actin and myosin, the major molecular motor complex in the cytoplasm.
Developing a system for observing nuclear motion was difficult because chromosome movement is extremely light-sensitive. One exposure to light, and the chromosome would not move, even though the cell appeared undamaged. After extensive experimentation, researchers at UIUC developed a method that allowed them to take pictures without killing the movement.
Using this system, UIUC graduate student Chien-Hui Chuang studied a chromosome that is normally found in an inactive state near the nuclear periphery and moves to the interior of the nucleus when it receives an activating signal.
"The movement following activation was radically different from the rapid, but short-range, diffuse movement previously observed in these nuclei," said Dr. Andrew Belmont, professor of cell and developmental biology at UIUC, principle investigator and co-author of the study. It was clear that this was directed movement that required a motor, Belmont said, because the chromosome was moving in a nearly straight line perpend

The variable $RANDOM (actually a bash function) returns a random number from 0 to 32767 inclusive.
You would typically want to limit its range by dividing it by some number and take its remainder, eg.
# output a random number 0 to 3
echo $((RANDOM % 4))
In this simplistic example it'll be very slightly biased for any divisor that doesn't divide equally into 32768 (eg, anything that isn't a power of two), but in your scenario I don't think you'd be troubled by a slight bias.
To pick a random file, you'd name your files something like:
And then you can pick a random one with
# output a random file from file0.jpg to file3.jpg
echo "file$((RANDOM % 4)).jpg"

helpful use of RANDOM, I accepted! – Pandya Jul 7 at 5:55
Note that RANDOM % N doesn't result in an equal distribution unless the number of possible values of RANDOM (32768) is divisible by N. To see this, imagine the range of RANDOM was instead 0-4 (5 possible values), and N is 2: there's three ways for $RANDOM % 2 to yield 0 (if $RANDOM yields 0, 2, 4) but two ways for it to yield 1 (1, 3). For an equal distribution you'd have to find the greatest multiple of N that's smaller than 32767 and ignore any random values that are larger than that. In the previous example that'd amount to ignoring 5, which is larger than 4. – Doval Jul 7 at 14:43
_USER_ I said that in my answer, did you see it? – neon_overload Jul 8 at 2:05
_USER_ My bad, I missed that bit. – Doval Jul 8 at 11:42
According to _USER_ answer (using RANDOM),
I can put RANDOM in example script as follows (for 4 commands):
random_selection=$((RANDOM % 4))
case $random_selection in
share|improve this answer
If you want randomness through an external site rather than one generated by your computer, you can use this script:
curl "_URL_
Run as rand (MIN) (MAX) (assuming you save as /usr/bin/rand)
You might have to install curl first (sudo apt-get install curl) if it is not already installed.

From the ALSA wiki
|The FAQs have been reorganized. The new location of this question is Mixer|
What is a Mixer?
A mixer is a device that controls the sound inputs and sound outputs on a soundcard. A mixer requires both hardware and software components. The hardware mixer is part of the electronics inside a soundcard. A software mixer is some software which provides a user interface for controlling the hardware mixer. Examples of software mixers include:
A software mixer does not control the hardware mixer directly; the ALSA sound driver is always an interface between the software mixer and the hardware mixer. This is because different soundcards have different interfaces to their hardware mixers. The purpose of the ALSA sound driver is to provide a standard interface for controlling the different hardware-mixer interfaces. This means one software mixer can work with many different soundcards. Typical examples of mixer controls are:
Master Volume (L,R) Bass Tone (L,R) Treble Tone (L,R) Line Input (L,R) PCM Volume (L,R) FM Synth Volume (L,R) CD/DVD Volume (L,R) Microphone Input Gain (L,R)
A software mixer usually has two separate controls for independently controlling the volumes of the left and right (L,R) channels of each stereo sound source. There may also be controls for mono sound sources, e.g. mono microphones. A mixer is implemented inside ALSA using a ctl-device.

Motor Cars / Trains of the Panama Railroad
Common labor traveled on labor cars converted from either 40' standard flat cars or from the old French 6 meter dump cars. The middle echelon American employees rode the passenger trains of the Panama Rail Road. The executives at the head-quarters at Balboa made their inspection trips using a fleet of motor cars.
Goethals had started his inspection trips each morning on the Panama Rail Road's morning passenger train. When the motor cars were built he had one reserved for his private use. This car also served as transportation for the important people who came from Washington.
The motor car became a commercial reality on the main line railroads of the United States beginning in 1905. William R. McQueen started building them for the Union Pacific Railroad where he was the Superintendent of Motive Power. By 1907 six of his cars were in operation on the Union Pacific.
The cars used by the I.C.C. were based at Balboa. They were weird and wonderful contraptions with the six cylinder gasoline engine's radiator perched on the roof. The passenger car body towered over the tiny gasoline motor housing and was styled in the best tradition of the previous century.
Because they ran on the Panama Rail Road they complied with the rule book requirements for designating a train They had marker lamps, sockets for flags for daytime operation designating the class of train, headlights, and a compressed air horn.

length of an amah equals 53.34 centimeters or 21.0 inches. Cf., Encylopedia Talmudit, II, 29, where the length of an amah is given as 54 centimeters according to Arukh ha-Shulhan.
Teshuvot Hatam Sofer states that the length of a fingerwidth is a "zoll." Since a biblical amah is equal to 24 fingerwidths, the length of an amah according to Hatam Sofer equals 24 zoll. Da'at Torah, Yoreh De'ah, Kuntres Aharon 35:116 states that the zoll is equal to 2.6 centimeters. That calculation is apparently also assumed by Darkei Teshuvah and Encyclopedia Talmudit. [Cf., however, Encyclopedia Britannica, loc. cit., which describes the zoll as a Swiss unit of measure equal to 3 centimeters.] Encyclopedia Talmudit, ad locum, indicates that, according to Hatam Sofer, the length of an amah is 62.4 centimeters or 24.567 inches. Thus a mil, according to Hatam Sofer, would equal 1248.0 meters or 4094.49 feet. Darkei Teshuvah 19:27 notes that the amah was marginally enlarged by rabbinic decree and, accordingly, should be calculated as 241/2 zoll. Darkei Teshuvah endorses the position of Hatam Sofer and states that the length of an amah according to Hatam Sofer is 63.8 centimeters. Thus, according to Darkei Teshuvah, an amah equals 25.12 inches and, accordingly, a mil equals 1276 meters or 4186.35 feet. Hatam Sofer's calculations are thus significantly greater than those of the earlier-cited authorities.
Darkei Teshuvot also cites a certain "Rabbi of Yasi" who calculated the amah as "no more than" 52 or 53 centimeters and an anonymous scholar who differed and calculated the amah as approximately 581/2 centimeters. Darkei Teshuvah also quotes She'erit Yisra'el, Parashat Mezora, who calculates the amah as 211/6 zoll or 56 centimeters and further opines that one who calculates the amah as 221/8 zoll or 57 centimeters is to be commended. Darkei Teshuvah cites an additional source for the latter calculation as well.
Da'at Torah, Yoreh De'ah, Kuntres Aharon 35:116, cites authorities who variously posit the length of an amah as 47 centimeters, 55.25 centimeters, a bit more than 57 centimeters and 58.5 centimeters, as well as one authority who asserts that according to Rashi the amah equals 43.8 centimeters, according to Shakh 45.02 centimeters, according to Taz 47.34 centimeters and according to Rambam 50 centimeters. See also the measurements ascribed to earlier authorities by Rabbi Weiss, Midot u- Mishkalot shel Torah, pp. 198-264 as well as the table presented ibid., introduction, p. 8. See also R. Moshe Shimshon Bacharach, Hut haShani, no. 97.
For a table correlating many of these measurements of the amah with the volume of the liquid revi'it see Midot u-Mishkalot shel Torah, introd., p. 8. Rabbi Kanievsky, Shi'urin shel Torah, p. 51, cites a discussion in the Palestinian Talmud, Terumot 10:7, that is understood by some authorities, including Riva, Commentary on the Pentateuch, Parashat Mishpatim; Ma'adanei Yom Tov, Berakhot 3:30; and Tosafot Yom Tov, Pe'ah 6:6, as indicating that a revi'it equals 240 grams. If so, an amah would appear to equal 73.368 centimeters or 28.885 inches. Rabbi Kanievsky categorizes that calculation of the revi'it as "extremely large" and as "not imagined by earlyday authorities."

Amah = Hamah = one of the three words for the Sun
Radius of the Sun (R) = 695,_PHONE_ km

The Liberation Health Group is open to all advocates of social justice and human liberation involved in the struggle for a healthy society. We understand "health" as more than the absence of disease and are committed to addressing the personal, cultural, and institutional barriers that prevent us from being healthy!
Members of our group work to better understand liberation health theories and methodologies in the practice of client empowerment. We strive to link immediate issues and struggles relating to our current health care system to the larger societal structures that regulate it and the dominant worldview messages that rationalize the existing unjust allocation and distribution of resources and services.
As health care workers and clients, we recognize the need to ally with our brothers and sisters who are experiencing oppression, here in Boston, and around the world. Our solidarity with the individual clients, families, and communities with whom we work means recognizing their right to meaningful participation in the health decisions that affect their lives.
We propose and fight for alternative forms of social organization that promote a more just distribution of natural and human resources and a healthy society that prioritizes human needs over accumulation of capital and profit. We identify with the oppressed, dominated, and marginalized of the world and their struggles to achieve economic, political, and cultural freedom and self-determination.

Public-Private-Civil Society Partnership: A Gateway to Ensuring Good Governance Practices of Vocational Education Programme in South-South Nigerian Federal Universities
There is an increasing evidence that education generally and vocational education particularly in Nigeria is facing serious challenge of financial resource mismanagement, which seem to be traceable to high level of corruption or corrupt practices exhibited by school administrators. This unpleasant situation has contributed to lack of effectiveness and efficiency, accountability, transparency, and integrity in the utilization of funds for execution of projects. However, the quest to achieve the main objectives of vocational education appears to be rather unrealistic. Therefore, the issue of mismanagement or lack of clarity in the utilization of funds for execution of projects have called for the coalition of all major stakeholders within and outside Nigeria so as to help bypass the corrupt governance of vocational education programme. This study aims at investigating the extent to which public-private-civil society partnership (PPCSP) can help in establishing good governance practices of vocational education programme in Federal Universities in South-South geopolitical region of Nigeria. Four research questions were raised and answered using the Mean and standard deviations descriptive statistics, and four corresponding null hypotheses were formulated and tested using the t-test statistic. A descriptive survey research design was employed for the study. The study population comprised of all the vocational education lecturers in South-South Nigerian Federal Universities. A 4-point scaled questionnaire was administered to 154 vocational education lecturers. The instrument was validated by 4 experts, and the reliability coefficient using Cronbach alpha was α=.90. The analysis of the data collected revealed that to a very high extent PPCSP can help in promoting good governance practices (e.g., effectiveness, efficiency, transparency, accountability, and integrity) in the utilization of funds for execution of projects by vocational education administrators. When the corresponding null hypotheses were tested, the study found no significant difference in the Mean responses of male and female vocational education lecturers as regards the extent to which PPCSP can help in promoting good governance practices in the utilization of funds for execution of projects. Based on these findings, there is the need for all the major stakeholders of vocational education within and outside Nigeria to collaborate in order to promote good governance practices in the utilization of funds for execution of projects by vocational education administrators.

It's a ajax call through jQuery
Then give jQuery a JS object of the parameters:
 url: '/something.url',
 data: {character_id: id, correct: correctOrIncorrect}
If you try to create a serialised data string of your own, you will have to worry about getting the URL-encoding right. So let jQuery work it out instead.

Eyenalyze uses four Hubs to house the various functions needed to manage a restaurant. Each Hub are represented by a color coded tab. Sales is represented by blue, Inventory is yellow, Labor is red, and Profit is green. These colors are consistent throughout the platform.
The Dashboard automatically opens up with Sales. Navigating the tabs changes the color and data appearing on the Dashboard. Each Hub has its own personalized set of charts and graphs used to present data for a restaurant. Each Hub also has its own menu of functions, called the Fuse Panel, that can be reached by clicking the header for each Hub.
Eyenalyze contains a date range function that is present throughout the platform allowing users to manipulate data by time.
To navigate the date range box, select a predetermined date range, or manually define a start and end date by selecting the desired dates on the calendars. When changing a date range, data throughout Eyenalyze will update to present the selected date range.
Users can use this to view a restaurants data for any specific day, week, month, or year.
At the top of every page in Eyenalyze a user can quickly access the Dashboard, or a specific Hub, by selecting the respective quick link located below the restaurant name.
The first symbol is for the Dashboard, then Sales Hub, Inventory Hub, Labor Hub, and Profit Hub, respectively.
Various pages in Eyenalyze have a wrench icon, called the Edit Menu, that allows users to further edit or use the platform. The Edit Menu is always located next to the title of the page.
Each Hub on the Dashboard has a chevron symbol on the right hand side that acts as a drop down menu allowing users to quickly access a specific Fuse within the Hub.
There are two ways to switch between restaurants using the Eyenalyze platform:
- In the top right menu, select "Restaurants" and options for available restaurants will appear.
- Select the restaurant name on the page and the option to search or scroll to a new restaurant will appear.
The Eyenalyze platform is centered around data tables for users to view information. Most tables with information in Eyenalyze are a data table, and can be sorted by each vertical category available. Simply click the header and the table will sort "A to Z" or "Z to A" respectively.

Part 2: Inverse Variation
Inverse variations are excellent vehicles for investigating nonlinear functions. A number of real-world phenomena are described by inverse variations, and they are typically the first functions that students encounter that do not cross either axis on a graph.
An inverse variation is a situation in which one quantity increases while another quantity decreases -- such as the number of diners and serving size for a given amount of food, or speed and travel time for a given distance. The product of the quantities remains constant; that is, as one quantity doubles, the other quantity is cut in half.
A caterer who takes a watermelon to a picnic knows that each person will receive more watermelon if there are fewer attendees, but each person will receive less watermelon if there are more attendees. That's because the amount of watermelon for each person varies inversely as the number of attendees. The more people, the less each person gets.
A truck driver knows that driving at 75 miles per hour will get her to her destination faster than driving at 65 mph, because time is inversely proportional to speed. As her speed increases, her travel time decreases.
- The length (l) varies inversely as the width (w) for a rectangle of constant area (A); that is, A = lw.
- The depth (h) of oil in a cylinder varies inversely as the area of the cylinder's base (B); that is, as the cylinder becomes narrower, the oil becomes deeper, or V = Bh.
Inverse variation: When the ratio of one variable to the reciprocal of the other is constant (i.e., when the product of the two variables is constant), one of them is said to vary inversely as the other; that is, when
or xy = c,
y is said to vary inversely as x.
(Source: James, Robert C. and Glenn James. Mathematics Dictionary (5th edition). New York: Chapman & Hall, 1992)
Two objects that vary inversely are also said to "vary indirectly" or to be "inversely proportional."
Alternative definition: One quantity is inversely proportional to another when the product of the two quantities is constant. An inverse proportion can be described by an equation of the form xy = k, where k is the constant of proportionality. The equation of an inverse proportion can also be written in the form.
(Source: SIMMS Integrated Mathematics: A Modeling Approach Using Technology; Level 1, Volume 2. Simon & Schuster Custom Publishing, 1996)
Role in the Curriculum
Inverse variation provides a rich curricular complement to direct variation. As teacher Peggy Lynn says in the Workshop 7 video, "I like teaching these two topics in the same context because of their relationship to each other." The constant of proportionality in a direct variation represents a quotient; by contrast, the constant of proportionality in an inverse variation represents a product. "Division and multiplication go hand in hand, so the students can relate to that," Peggy says.
Direct variation and inverse variation are related topics, and it makes sense to study them in parallel. Because they have striking differences, the contrast allows students to gain a deeper understanding of various functions. "Students should have experience in modeling situations and relationships with nonlinear functions," according to the PSSM. Inverse variation allows students to consider nonlinear functions. The graph of an inverse variation never crosses the x-axis or the y-axis, nor does it pass through the origin. "[Students] should connect their experiences with linear functions to their developing understandings of proportionality, and they should learn to distinguish linear relationships from nonlinear ones," the PSSM states.
When teaching inverse variation - as with direct variation and other activities involving mathematical modeling - asking students to gather data helps to spark their interest. Students are required to think more when investigating a phenomenon using a hands-on approach, though they often don't realize they're learning because they're having fun. In addition, when students are exposed to "messy data," they must make thoughtful decisions in order to identify functions that fit the data well enough to be useful in making predictions. Making sound mathematical decisions is the basis of effective modeling, so providing opportunities for students to make choices helps to develop their analytical abilities.
For real-world explorations involving inverse variation, it will be necessary to collect enough data to make the nonlinear pattern obvious. Too few points may result in a pattern that appears to be linear. Once sufficient data have been collected, students can use tables and graphs to represent the data.
Finally, students should compare direct variation with indirect variation, illuminating the differences and highlighting the similarities. For instance, they might describe the relationship between the general equations
y = kx and. They should recognize that the constant of proportionality in the direct variation is a quotient of the variables, while the constant of proportionality in the inverse variation is a product. Or they might consider the graphs, since a direct variation is linear and passes through the origin, while an inverse variation is a curve with no x- or y-intercepts. Making these comparisons will allow students to understand the differences within a family of functions.

Lexington's Carnegie Library
Lexington's library has a long, distinguished history. Established in 1795, it is now the oldest institution of its kind in Kentucky and possibly the oldest in the west. The library was started with 400 books, which were added to the collection that already existed at the Transylvania Seminary. The library was based on subscription wherein people paid for the use of the library holdings. In 1898, Lexington was deemed a second-class city by the Kentucky Legislature and this classification enabled the city to acquire and conduct a free library. The Carnegie Library, also known as the Lexington Public Library, was built in 1906 as a gift to the city of Lexington from the Andrew Carnegie Foundation. To receive its donation, the Carnegie Foundation required the city to provide a site for the library and to appropriate funds for the library's upkeep. The new building was constructed of Bedford limestone and was built for a sum of $75,000. Thereafter, the contents of the library were moved to their new home, a beautiful Neo-Classical building at the southern end of Gratz Park. During the late 1980s the Lexington Public Library built a new, larger central branch on East Main Street to accommodate its growing collection. The Carnegie Library is now the home of the Carnegie Center for Literacy and Learning. This organization provides many free, public programs to help spread literacy and to promote reading among children.

Send Your Name to Mars
For all those who submitted your names, Congratulations! Your name was successfully etched onto a microchip and is officially on Mars!
How did NASA collect the names? More than 1.2 million names were submitted on our web site over a one year period! Some 20,000 visitors to NASA's Jet Propulsion Laboratory, Pasadena, Calif., and NASA's Kennedy Space Center, Cape Canaveral, Fla., wrote their names on pages that were scanned and reproduced at microscopic scale onto two chips the size of a dime.
How were the chips made? Engineers etched the names onto a silicon wafer or microchip. They used an electron beam "E-beam" machine at JPL that specializes in etching very tiny features (less than 1 micron, or less than the width of a human hair!). They normally use this machine to make high-precision microdevices in JPL's Microdevices Laboratory.
Leonardo da Vinci's Codex on Bird Flight, a document from about 1505 was reproduced on a microscopic scale and fastened to the chip on Curiosity. Leonardo's self-portrait is also on the rover, along with some essays, drawings, and other submissions from finalists and semi-finalists who participated in the "Send Your Name to Mars" rover naming contest opportunity.


What minimum information is required before I can calculate a payroll deduction?
For each type of payroll deduction calculation (Regular Salary/Pension/Bonus/Retroactive Pay/Commission), there are different required information fields that must be completed by the user before a payroll deduction calculation can be done. For all types of income except Commissions, the user must specify a Pay Period definition - i.e. weekly, bi-weekly, semi-monthly, etc. For ALL calculations, the user must also specify the Quebec TP1015_3V - Total Claim Amount. For Commission income, the user must specify additional information from the commissioned employee's federal TD1X form. Any required information for a payroll deduction calculation will be documented in the QPTL documentation included with the QPTL API/SDK package. The user must ensure that valid information is provided in these required fields before sending requests to the QPTL library method(s).

How to Get Mold Smell Out of Dresser Drawers
Mel Frank
Dressers are a perfect way to store clothing, keeping it safely out of sight yet on hand and quickly accessible. The problem is that these drawers are dark, typically sealed off when closed, and can quickly develop moisture that leads to the development of a musty, moldy odor. To remove the odor, simply treat the drawers with a quick odor removal solution.
Get rid of mold smell with ease.
 1. Place a small dish of baking soda in each drawer. The baking soda is a natural odor absorbant that will also draw any moisture out of the drawers. Let the baking soda sit overnight.
 2. Fill a spray bottle with white vinegar. The vinegar is a deodorizing agent and will also kill any mold or mildew growth that is causing the odor.
 3. Spray the vinegar solution into all of the drawers.
 4. Keep the drawers open, and allow the drawers to air out overnight.
 5. Repeat if needed if all odor has not dissipated.


Decoding the architecture of vascular networks.
Eleni Katifori, Rockefeller University
Distribution and structural networks permeate virtually all life, from the cellular to the organismic level. They have allowed organisms to grow in size and complexity by ensuring efficient distribution of nutrients and structural support. Given their importance, these vascular and structural webs have been under strong evolutionary selection and their form frequently reflects important aspects of their function. Using optimization models we examine the design principles behind the evolution of the architecture and topology of vascular and structural networks. Standard complex network tools are not sufficiently nuanced to compare the highly nested architecture that is frequently observed in naturally occurring webs with in silico models. Thus, we develop an algorithmic framework that quantifies the hierarchical organization and topology of weighted graphs dominated by cycles and present some examples (leaf venation, arterial vasculature of the neocortex and others) that elucidates it.
