I took $3$ random polynomials with non zero roots one having even degree and two having odd degrees
 1. $f(x)=\color{red}{4}x^2-(4\sqrt3+12)x+12\sqrt3$ having roots $\color{blue}{3,\sqrt3}$ and leading coefficient $\color{red}{4}$ and calculated values of $xf'(x)$$(f'(x)$ is the derivative of $f(x))$ at both roots which are $3f'(3)$ and $\sqrt3f'(\sqrt3)$ and then sum of their reciprocals $\frac1{3f'(3)}+\frac1{\sqrt3f'(\sqrt3)}=\frac{-1}{12\sqrt3}=\frac{-1}{\color{red}{4}}\left(\frac{1}{\color{blue}{3\cdot\sqrt3}}\right)$ then repeated same thing for
 2. $g(x)=\color{red}{1}x^3-\frac{20}{3}x^2-12x+\frac{32}{3}$ having roots $\color{blue}{8,-2,\frac{2}{3}}$
 $\frac1{8g'(8)}+\frac1{-2g'(-2)}+\frac1{\frac{2}{3}g'(\frac2 3)}=\frac{1}{\color{red}{1}}\left(\frac{1}{\color{blue}{8\cdot-2\cdot\frac2 3}}\right)$
 3. $h(x)=\color{red}{1}x^5+41x^4+137x^3-1601x^2-1818x+3240 $ having roots $\color{blue}{1,-2,5,-9,-36}$
 $\frac1{1h'(1)}+\frac1{-2h'(-2)}+\frac1{5h'(5)}+\frac1{-9h'(-9)}+\frac1{-36h'(-36)}=\frac{1}{\color{red}{1}}\left(\frac{1}{\color{blue}{1\cdot-2 \cdot5\cdot-9\cdot-36}}\right)$
Is this true for all polynomials? Is there any known result?

 $\begingroup$ If the polynomial has a double root, then it is a root of its derivative, and the expression is not well-defined. $\endgroup$ – Daniel Aug 16 '19 at 17:06

This results from partial fraction decomposition.
Suppose $g(x)$ has no repeated roots, and without loss of generality is monic (leading coefficient $1$). Then it factors as $\displaystyle g(x)=\prod_{r}(x-r)$ over all roots $r$ and
$$ \frac{1}{g(x)}=\sum_{r}\frac{c(r)}{x-r} $$
for some constants $c(r)$, one for each root $r$. To find the constant $c(s)$ for a specific root $s$, first multiply the equation by the factor $(x-s)$,
$$ \frac{x-s}{g(x)}=c(s)+\sum_{r\ne s} c(r)\frac{x-s}{x-r} $$
then "evaluate" i.e. take the limit $x\to s$ to obtain
$$ \frac{1}{g'(s)}=c(s). $$
Therefore we may plug $x=0$ into
$$ \frac{1}{g(x)} =\sum_{r} \frac{1}{g'(r)(x-r)} $$
and manage negative signs to get
$$ \frac{(-1)^{\deg g}}{\displaystyle \prod r} = -\sum_{r} \frac{1}{rg'(r)}. $$
When $\deg g$ is odd, all signs can go away.
 - $\begingroup$ Beautiful! And I managed to understand all steps! $\endgroup$ – Zamu Aug 16 '19 at 23:22
It is true for all polynomials with non-zero simple roots.
This follows from the barycentric form of Lagrange interpolation: $$ L(x)=\ell (x)\sum _{j=1}^{n}{\frac {w_{j}}{x-x_{j}}}y_{j} $$ where $$ \ell (x)=(x-x_{1})(x-x_{1})\cdots (x-x_{n}), \quad w_{j}={\frac {1}{\ell '(x_{j})}} $$ Therefore, for the constant function $1$ evaluated at $x=0$ we have $$ 1= L(0) = -\ell (0)\sum _{j=1}^{n}{\frac {1}{x_{j}\ell '(x_{j})}} $$ For a polynomial $f$ with simple roots $x_1, \dots, x_n$, we have $$ f(x)=a(x-x_{1})(x-x_{1})\cdots (x-x_{n})=a\ell (x) $$ and so $$ \sum _{j=1}^{n}{\frac {1}{x_{j}f'(x_{j})}} =\sum _{j=1}^{n}{\frac {1}{x_{j}a\ell '(x_{j})}} =-\frac{1}{a\ell(0)} =-\frac{1}{(-1)^{n}ax_1 \cdots x_n} =\frac{(-1)^{n+1}}{ax_1 \cdots x_n} $$ This can also be written as $$ \sum _{j=1}^{n}{\frac {1}{x_{j}f'(x_{j})}} =-\frac{1}{f(0)} $$

How to describe animals
Slow worms are not worms, and they are not slow.
Sometimes confusion must come before clarity. And that is never more true than when describing our native UK wildlife.
For example, slow worms are not worms, and they are not slow.
Whales swim in our seas, but the impressive killer whale, which frequents the coast of northwest Scotland, is not a whale at all. That is why many call it an orca.
Bucks roam our countryside: male deer, hares, ferrets and rabbits are all bucks. But interestingly, none actually buck (only horses do). Rabbits give birth to kittens, but kittens can also be baby cats.
It's almost impossible to describe a butterfly that cannot be a moth, and a moth that cannot be a butterfly, while similar is true for frogs and toads.
The common names of animals are nouns. But when describing animal behaviour, the same words are sometimes used as verbs.
 - A perch is a freshwater fish, whereas birds might perch on a branch. It is an accident of language that the same word is used both ways. It is no accident that swifts, those fast flying birds that look similar to swallows, are called swifts. That's because they fly fast.
 - Buck (noun) is a name given to the males of many species. Its origin is thought to be the German word buc, meaning deer. However, the verb 'to buck' can only be applied to a jumping horse.
Verbs can also be turned back into nouns to help describe wildlife.
 - Animals such as moles that burrow become burrowers
 - Whales or barnacles that filter the water for food are filter feeders etc.
Birds perch, while perch swim in our lakes. And those killer whales we mentioned are predatory mammals, that have sharp teeth and eat meat. But they are not carnivores, not strictly speaking. Other iconic black and white creatures, our badgers, are also mammals, though not nearly as predatory. They have sharp teeth, but eat less meat. Yet they are technically carnivores.
You have every reason to be, because much confusion around how we describe wildlife comes from the confusing ways in which we name it.
So when you describe wildlife, it's important to understand which type of name you are using, and why that matters.
For example, wildlife can be described by their common names, i.e. a badger, perch or deer.
Wildlife can also be described by the group of animals to which they belong; badgers are mammals.
By their behaviour; a badger is an omnivore that eats a variety of foods.
Or by their scientific group; technically a badger is a carnivore, not because it eats meat, but because it is related to other weasel-like animals, as well as dogs, cats, bears and seals that share a suite of inherited characteristics, such as sharp carnassial teeth. All these animals belong in the order Carnivora, which is why badgers are technically carnivores.
Common names
Most people know animals by their common names, and there are no hard and fast rules as to what these should be.
Lapwing: BBC Nature A peewit, hornpie or lapwing?
Commonly used descriptions and names for much wildlife have changed with time and vary by location, spelling and capitalisation.
A lapwing, a small wading bird, is variously called a peewit, green plover, teuchit, hornpie or flopwing, depending on its location in the UK. In Gaelic it is a curracag. In Irish a pilibín.
Many names and descriptions have become an integral part of our cultural landscape, influencing the names of drinking establishments, towns, how we speak, and our art.
Think of a pub called The Swan in Shrewsbury. There, a local might ask another to stop badgering them, as they want to read Watership Down, a classic English novel about a group of rabbits given human characteristics.
Start Quote
End Quote From the best-selling novel Watership Down by Richard Adams
The attributes we assign to wildlife are often co-opted, becoming more widely understood cultural symbols. The thistle of Scotland symbolises nobility and chivalry, an example of floriography.
Because common names vary, they can cause confusion.
But giving a little-known, perhaps new species a common name is also a powerful way to be able to remember it, talk about it, and make people care about it.
Natural England runs an annual competition to name newly discovered British species for this reason. In 2012, it named a rare wasp that lives in southern England as the Cutpurse wasp, due to its habit of feeding exclusively on purse web spiders.
Animal types
Animals or plants can be informally grouped, defined often by their behaviour or where they live; such as flying insects, or forest flowers. These groupings often have no formal scientific basis.
Or they can be formally grouped into scientific categories. Each of these groups is defined by a suite of characteristics that each animal or plant within must share.
Badgers (once known as brock) are mammals, belonging to the scientific grouping Mammalia. Like badgers, all mammals have fur and all female mammals have mammary glands, which they use to provide milk for their young.
Badger: BBC Nature Brock the badgering badger
Swifts are birds, belonging to the scientific group called Aves. All birds have feathers and wings.
There is no single scientific grouping of fish, however. It is a common name used to describe animals that swim, have fins, and look like 'fish'. Scientists group fish into discrete categories. Some fish have bony skeletons, and are known as Osteichthyes. Others, such as sharks, have skeletons made of cartilage and are called Chondrichthyes.
To understand how scientists formally group and name animals it is important to understand how the Linnaean system of nomenclature works, a classification system that is easier to grasp than it sounds.
Animal behaviours
We often describe animals by their behaviour; where they live, when we see them, what they like to eat, and how they go about acquiring their food, for example.
Describing wildlife in this way can be a valuable way to communicate important information about them, to help find or identify them, or study the common challenges they face.
Marsh frog: BBC Nature Marsh frog or pond life?
Nocturnal animals appear at night, for example. All of them, whether they are bats or badgers, have to be able to move around or navigate in the dark. They develop different senses to help them; either evolving big eyes, ways to use sound to navigate, such as bats using echolocation, or perhaps a super sense of touch, used by moles.
Day living animals are described as diurnal.
Wildlife is often described by the habitat it lives in; pond life, for example.
Or by how it eats; hawks are predators because they hunt other animals. Herbivores such as deer are grazers or browsers.
The heritage and origin of animals and plants can determine how we describe them: invasive species are those that have 'invaded' another habitat, territory or country to which they don't naturally belong.
Scientific names and relationships
As described above, scientists use a specific language when naming species, and that language is governed by a set of rules.
All barn owls in the UK are members of the species Tyto alba. They are the same as barn owls flying all around the world, from South America to Africa and Europe, even if many of these birds may look subtly different.
This system underpins many of our efforts to understand wildlife, its evolution and how it should be conserved.
You decide
There's nothing wrong with describing animals in a personal way, or giving them a generic name, if you are unsure. People might variously call a cockchafer beetle a May bug, mitchamador, billy witch, or spang beetle.
White Hart pub sign A White Hart is a pub and white deer
Occasionally this can lead to confusion. Unless you have a good grasp of mediaeval history, or frequent lots of pubs, you might not know that a White Hart is actually a white deer. Or that an Essex skipper is a type of butterfly that lives far beyond Essex.
But what really matters is that you use the description that works best for you.
If you work in science, you will likely describe wildlife using the formal Linnaean naming system. Other scientists will then understand exactly which species you are describing.
If you live in one part of the country, you'll likely do best using the local, common name for wildlife that people will understand in conversation.
The more you discover and celebrate wildlife, the more you will feel comfortable describing what you see, using the appropriate language.

Jerome Jay Wolken, a biophysicist at Carnegie Mellon University in Pittsburgh who delved into the mysteries of sight and light and invented a lens system that gave sight to some legally blind people, died on May 10 at his home in Pittsburgh. He was 82.
Dr. Wolken's Light Concentrating Lens System, developed in the 1980's and used in eyeglasses, opened new vistas on medical science, photography, astronomy and the collection of sunlight. One of the patents for the system involves a pear-shaped lens 10 times more sensitive to light than a standard camera lens.
The system reproduced the lenses that deep-sea creatures adapted over millions of years to see objects at depths of up to 1,500 feet in almost total darkness. The key was a special geometric relationship between the curvature of the top and the curvature of the bottom of the lens.
Made of glass or plastic for an eyeglass frame, the system increased the light-gathering ability of eyes that could not send enough light to their retinas. It was used primarily by people with cataracts.
In researching deep-sea optics, Dr. Wolken worked with the Marine Biological Laboratory and the Oceanographic Research Institute at Woods Hole on Cape Cod, Mass., and with similar institutions in Miami, Bermuda, the Bahamas, Europe and Japan. He applied his findings to lenses of enhanced photosensitivity.
Jerome Jay Wolken was born in Pittsburgh and received a bachelor's degree in chemistry from the University of Pittsburgh in 1946. He received a master's degree in biological sciences in 1948 and a Ph.D. in biophysics in 1949, both from Pittsburgh, where he taught in the 1950's and was named a professor of biophysics physiology in 1962.
Two years later, Carnegie Mellon appointed Dr. Wolken a professor and head of the biological sciences department at Morrison Carnegie College. He wrote nine books in his field, edited two more and contributed some 120 papers to scientific journals. He retired in 1982, but he continued his work until recently.
Dr. Wolken is survived by his wife of 43 years, Tobey Holstein Wolken; their daughter and son, Johanna Zorn of Chicago and Erik A., of Chapel Hill, N.C.; a daughter and son by an earlier marriage, Ann Wolken of Los Angeles, and Jonathan, of Washington Depot, Conn., and five grandchildren. His first wife, Dorothy Mallinger Wolken, died in 1954.

The Amazon milk frog is found in tropical rain forests in northern South America. It lives its entire life in the forest canopy and rarely, if ever, descends to the ground. This species is considered large for a tree frog and adults usually range in size from 2.5 to 4 inches. Males are smaller than females.
The coloration of an adult Amazon milk frog can range from dark brown with light grey or white banding, to light grey with dark brown banding. Juveniles are banded black and white. The eyes are golden in color with a black Maltese cross centered on the pupil. There is a vocal sac on each side of the head.

SILAMOL BRASIL POTATO crop leaf application 2012.pdf
The objective of this work was to evaluate the effects of silicon leaf application, in the form of stabilized silicic acid, on the disease incidence, yield, and quality of potato. Three experiments were carried out: one with the cultivar Agata and another with Atlantic, in Botucatu, SP, Brazil; and one with the cultivar Agata, in Itaí, SP. A randomized complete block design was used, with eight replicates. The treatments consisted of: a control (without Si) and Si foliar spraying at 2 L ha‑1 of a commercial product containing 0.8% of soluble Si as concentrated, stabilized silicic acid. The silicon dose was split in four applications during the crop cycle. Silicon application reduces the severity of late blight and the incidence of blackleg, besides increasing tuber
yield and tuber dry matter content. Leaf‑supplied silicon increases potato tuber yield, regardless of its effect on disease incidence.

Keyhole Markup Language (KML) is an XML notation for geographic applications. The advantages of using KML are numerous, and have been listed in a previous article. The learning curve for KML is quite steep, requires a thorough understanding of both XML and mapping technologies, and since the reference documentation is written for 3d rather than 2d maps, much of it is irrelevant for simple mapping cases. All this means that some web developers are put off using KML, which is a pity, since KML is a standard data format, and the use of KML would result in the faster porting of a mapping applications to other platforms.
In order to remedy this, it would be useful to have a WYSIWYG point and click KML generator, where a map could be edited on screen, and the resultant KML file generated. The coded example below, attempts to fill this gap as shown.
After the usual Map set up, we need to get a reference to each of the text boxes on the right of the screen. This is done by using document.getElementById()
var lat = document.getElementById("lat");
var lng = document.getElementById("lng");
var waypoints = document.getElementById("waypoints");
var title = document.getElementById("title");
var name = document.getElementById("name");
var description = document.getElementById("description");
var address = document.getElementById("address");
var icon = document.getElementById("icon");
var styleURL = document.getElementById("styleURL");
var lineStyleURL = document.getElementById('lineStyleURL');
Adding Markers
Markers can be added by pressing and holding down the mouse, this is the longpress event. An event handler has been added to the map to cope with this. The associated values such as and come directly from the text boxes defined above.
eventExEl.addListener("longpress", function(evt) {
var markerData = new Object();
markerData.coords = map.pixelToGeo(evt.targetX, evt.targetY);
markerData.title = map.objects.getLength() + 1;
markerData.description = description.value; = name.value;
markerData.address = address.value;
if (icon.value!= ""){
markerData.icon = icon.value;
} else {
markerData.styleURL = styleURL.value;
}, false);
An alternative method of adding a marker is by adding an address. This uses the standard geoCoding service, and picks the first address found on the list. If your address is in the "wrong" format, just try making the address more general for now e.g.try the city only. The handler for geo-coding retrieves most of its information from the text boxes on the right hand side of the screen, but the address comes from the callback function.
var searchManager =;
searchTerm : address.value,
onComplete: onSearchComplete});
 var onSearchComplete = function (data, requestStatus) {
// If the search has finished we can process the results
if (requestStatus == "OK") {
var markerData = new Object();
markerData.coords = data.location.position;
markerData.title = map.objects.getLength() + 1;
markerData.description = description.value; = name.value;
var address = data.location.address;
markerData.address = "";
markerData.address = markerData.address + address.houseNumber + "\n";
markerData.address = markerData.address + address.street + "\n";
markerData.address = markerData.address + address.district + "\n";
markerData.address = markerData.address + + "\n";
markerData.address = markerData.address + address.postalCode + "\n";
markerData.address = markerData.address +;
} else if (requestStatus == "ERROR") {
alert("The search request failed.");
The addMarkers() method actually adds the marker, which itself contains a copy of its own , , & etc. The marker has two events:
 - a click event to display the data in text boxes for editing. This will also display an infobubble if the field is set. A reference is kept on the currentMarker i.e. the last one selected.
 - a drag event to remove the infobubble if a marker is repositioned. All markers are defined as draggable so the user can reposition them as necessary.
function addMarker(markerData) {
var marker;
marker = new, {
text: markerData.title, //small title
draggable: true, //the marker is marked to be draggable
$data: markerData
marker.addListener("click", function(evt) {
title.value =;
description.value =$data.description;
address.value =$data.address;
name.value =$;
styleURL.value =$data.styleURL;
lat.innerHTML =;
lng.innerHTML =;
if ($data.description!= ""){
} else {
currentMarker =;
}, false);
marker.addListener("drag", function(evt) { infoBubbles.removeBubble();}, false);
Editing Marker Data
The editMarker() method, removes the currentMarker and adds another one with the current data from the text fields.
function editMarker() {
var markerData = new Object();
markerData.coords = currentMarker.coordinate;
markerData.title = title.value;
markerData.description = description.value; = name.value;
markerData.address = address.value;
if ( description.value != ""){
infoBubbles.addBubble(markerData.description, markerData.coords );
Adding Polylines
It is impossible to create Polylines without first having some defined waypoints. The waypoints are merely geo.Coordinates, so a button has been added to take the coordinates of the currentMarker and add them to an array. The marker is then removed to "tidy up" the display. When the create line from Waypoints button is pressed, the Polyline is created.
Warning.pngWarning: There is currently no method to delete waypoints or Polylines, this must be done by editing the KML directly.
var currentWaypoints = new Array();
currentWaypoints.push( currentMarker.coordinate);
function createLineFromWaypoints() {
var lineData = new Object();
lineData.lineNo = map.objects.getLength() + 1;
lineData.waypoints = currentWaypoints ;
if( lineStyleURL.value!= ""){
lineData.styleURL = lineStyleURL.value;
color: "#22CA",
width: 5,
$data: lineData
currentWaypoints = new Array();
waypoints.innerHTML = "";
KML Generator
The saveMapObjects() method has been taken from the converting from JavaScript to KML article. All the map Objects currently on screen are iterated through and added as KML equivalents. In order to discourage the use of inline styles, a element has been added. This should refer to a

I'm studying the Method of Images and I seemed to have come to a conundrum. Method of Images takes advantage of grounded objects, (I am currently studying spheres), to set boundary conditions. However, how would one use the idea of MoI to set the potential of a conducting sphere as constant?
Since $E = \nabla V$, a constant potential would be the electric field inside would be constant? Therefore, a density of charge inside the sphere?

I edited your question, to fix $\nabla E = V$, which should be $E=\nabla V$. but perhaps that typo is the source of your equation. – askewchan Feb 26 '13 at 2:04

1 Answer
Regardless of whether it is grounded, if there were a nonzero electric field inside a conductor, it would push the charge carriers around until there were no longer forces on them.
Thus: A perfect conductor, grounded or isolated, will have a surface (and volume) of equal potential, and the electric field inside will be zero.
If the conductor is not grounded, then there will be some net charge (possibly zero) on the conductor. If it's a symmetric shape (a sphere) then it will have a uniform surface density, namely the total charge over the total surface area ($Q / 4\pi r^2$).
You cannot assume to know $Q$ on the sphere. Whether or not $Q=0$, there will be $E=0$ inside the sphere (Gauss Law), and outside the sphere there will be $E\neq 0$ if $Q\neq0$.
Adding an image charge at the origin would actually create a nonzero $E$ inside the sphere, which you cannot have inside a conductor (I'm assuming the sphere is solid). The charge on the surface of the sphere already cancels its own $E$ field inside the sphere. If you want to cancel the $E$ field outside the sphere, then an image at the origin would do that.
share|improve this answer
So if I were to find the potential outside of a conducting sphere that is not grounded, the potential inside would have to be constant. Therefore that second image charge would have to be placed at the origin to mimic if it were grounded. – julesverne Feb 26 '13 at 17:53
_USER_ you really don't need an image charge to solve this, assuming you're trying to find the potential everywhere, just use Gauss' law. – askewchan Feb 26 '13 at 17:56

Data collection at Hunter Water condition assessment sites and initial model calibration
The aim of Activity 3 is to develop models for the description and prediction of the long-term corrosion losses and maximum pit depths of cast iron (and also steel) pipes buried in soil. The approach currently being pursued is to develop a corrosion model based on corrosion fundamentals and on documented field observations. The models will describe the amount of corrosion as a function of exposure period and the main influencing external soil conditions. Field data has recently been collected at a number of condition assessment sites within Hunter Water Corporation's network, and this data was used to calibrate an initial model for pipes buried in clay soils. A summary of this work is presented in this fact sheet. More details on this work are presented in Petersen et al (2013).

In this video, we're going to talk about refactoring your app using the Ember Composable Helpers addon.
Ember apps often have dynamic interface elements that let users explore their data. Here, we're looking at a shopping app that's displaying some clothes. We can see on the left that users can group clothes by type (we have shirts and pants) or color (blue, green and red). They can also filter by size - regular or tall.
Traditionally an interface like this might be built using a series of computed properties. Let's look at how this page was implemented.
On the left, we have this application's controller and on the right our template. The controller has a few pieces of state that it needs in order to render: the list of clothing items (referenced by the model property), the activeGroupBy option, and the activeSize filter. The computed properties then use this state to transform the clothing items array: filteredItems returns a subset of the original list, and groupedItems takes that filtered list, and transforms it into an object whose keys are the groups and whose values are the items belonging to each group.
The template then uses the standard each-in helper to iterate over the keys and values of the groupedItems object. Finally, it renders each group's items to the page.
We can also see how the interface elements themselves update the controller's state. For example, clicking on the "Color" button sends an action to the controller, which updates the activeGroupBy property. The computed properties are then recalculated, and as a result the interface re-renders.
Ember's Computed Properties work well here, but there's a lot of room for developers to make errors: the dependent keys for each property must be just right; there's a lot of boilerplate for these fairly generic transforms; and most of the code here is imperative and focused on implementation.
Let's see how we can use some simple, declarative template helpers from the Ember Composable Helpers library to clean up our code.
First, we'll install the library by running
 ember install ember-composable-helpers
Next, we'll pull up the documentation. Looking at the index of helpers, we see that the library includes both a group-by helper and a filter-by helper, which is exactly what our app needs. Let's start with group-by.
The docs show us that group-by takes two arguments: the property used to form each group, and the original ungrouped array of objects. Note that in our app, the user can actually change which property is being used to form each group, so we'll be using that dynamic property here, instead of a static string.
Let's go ahead and make the change. We'll replace groupedItems with the group-by helper, passing in the activeGroupBy property and our array of filteredItems.
- {{_TAG_-in groupedClothingItems as |group items|}}
+ {{_TAG_-in (group-by activeGroupBy filteredClothingItems) as |group items|}}
 {{_TAG_ items as |item|}}
Note that we're grouping the filteredItems array here, just like in our computed property, so that our filtering functionality still works.
With that change, we can see that our app renders, and the grouping functionality works - changing the group updates the template. The filtering functionality is also preserved. We can now go back to our controller and delete our groupedItems computed property. We already have a simpler controller and a more declarative template.
Now let's replace the filteredItems computed property. We'll use the filter-by helper. This helper takes a property to filter on, a value that satisfies the filter, and the original unfiltered array. We want to filter on size using the activeSize property, so we'll end up with something like this:
(filter-by'size' activeSize model)
This says we want to filter the original model by looking at each item's size property, and seeing if it matches the current value of activeSize - which can be either regular or tall.
Now, your first instinct here might be to assign this filtered list to a local property using the {{_TAG_}} helper, and then passing that result into our (group-by) helper:
{{_TAG_ (filter-by'size' activeSize model) as |filteredClothingItems|}}
This solution works, but we can do better. The Ember Composable Helpers library is built with composability in mind. This means that helpers can be used in conjunction with each other, which can save us from having to do things like creating temporary variables.
Instead of using {{_TAG_}}, let's leverage the power of subexpressions and compose filter-by with group-by directly:
Note that nested helpers evaluate right-to-left: first we filter the list by activeSize, and then we group the resulting array by activeGroupBy.
Looking at our app, we see that everything works as expected - meaning we can delete our filteredItems computed property. We've now eliminated both of our original computed properties, and we're left with a declarative template that's easy to read, change, and most important, relies on an addon to do its heavy lifting.
As with most things in programming, there are tradeoffs involved when using helpers to move controller or component logic into templates. In our example, we only needed two helpers; but you can imagine a series of computed properties that are much harder to replace.
Computed properties are still extremely useful in Ember applications. They're best suited for domain-heavy or complex transformations. You have the full power of JavaScript, and they're easy to debug and write unit tests for.
However, writing generic computed properties just to group or sort an array is unnecessary and error-prone. In these situations, Ember Composable Helpers is a great fit - and it's really fun to use! In fact, it's so fun that you'll need to be careful not to get carried away and start programming in your templates. The key is to find isolated, generic transforms you've written yourself, and replace them with battle-tested library code that you don't have to maintain.
So give it a shot in your own app! Install the library, and see how you can make your templates simpler and more declarative.'

Create SQLite database tables automatically from data
Project description
# DatatoTable Datatotable converts data into SQLites tables automatically. The package is most useful when the name and number of columns in a table are large or unknown ahead of time as SQLalchemy's Object Relational mapper (ORM) requires manual generation of tables and their columns. Datatotable automates this process. Yet, it still allows manual additions of constraints, foreign keys, and other properties as desired.
## Quick Start The minimal use case of datatotable creates a table from a data source, and then inserts the data. This example walks through this process. Datatotable functions through two classes Database, which provides access to the database, and DataOperator, which interprets data for use with SQLalchemy. First, import these classes. Next, import a SQLalchemy Session class for inserts and tempfile to create a temporary directory.
'python from datatotable.database import Database from import DataOperator from sqlalchemy.orm import Session import tempfile ' To connect to or create a database, specify the name and directory of the database on Database's instantiation. Then, connect a session to the database via Database's engine property. 'python temp_dir = tempfile.TemporaryDirectory() db = database.Database(name="sample", session = Session(db.engine) '
Next, pass data to DataOperator. The DataOperator's column property reads the data and returns a dictionary with column names as keys and lists of column attributes as values. 'python raw_data = {"col1": [1,2,3,4], "col2": ["hello", "world", "from", "computer"], "col3": [10.1, 13.5, 23.2, 98.4]} data = columns = data.columns print(columns) >>> {'col1': [], 'col2': [], 'col3': []} '
Pass the columns to Database's map_table() function to create a mapped SQLalchemy Base class. After the table is mapped, call the create_tables() function to create the table in the database. 'python db.map_table(tbl_name="example_tbl", column_types=columns) db.create_tables() '
With the table created, access the table via the Database.table_mappings property. The table mapping can be used for queries or mapping data for inserts. The row property of DataOperator returns a list of dictionaries where each dictionary is a row in the database. Use ** notation to unpack each dictionary into a table object. A list comprehension, as used here, can create a list of table objects. Add these objects using Session.add_all(). 'python example_tbl = db.table_mappings["example_tbl"] example_rows = [example_tbl(**row) for row in data.rows] session.add_all(example_rows) session.commit() '
Now, check if the data is in the database. 'python print(session.query(example_tbl).count()) >>> 4 '
## Version 0.3 This version is the first valid version uploaded to PyPi. It provides access to a database, automatically creates tables, and coerces data into a format that can be inserted into a table. It passes all tests in the test suite, but the test suite will need to be fleshed out as users come across problems not anticipated currently.
## Future Development ### Documentation 1. Use Sphinx to create API documentation on Read the Docs 2. A thorough tutorial to explain how constraints and relationships are established ### Functionality 1. Add functionality to relate SQLalchemy ORM objects when tables are created with foreign keys. This is a manual process currently. 2. Allow simultaneous creation of multiple tables. Tables must be created one by one currently.

'll have to scroll back to the function signature or use some IDE feature in order to see the return type and fully understand the return statement.
And here again it's not easy for someone reading the code for the first time to understand what is actually being constructed:
void DoSomething(const std::string &str);
const char* strValue =...;
size_t strLen =...;
DoSomething({strValue, strLen});
The code above is going to break when someone decides that DoSomething should also support some other string type, and adds this overload:
void DoSomething(const CoolStringType& str);
If CoolStringType happens to have a constructor which takes a const char* and a size_t (just like std::string does) then the call to DoSomething({strValue, strLen}) will result in an ambiguity error.
My answer to the actual question:
No, Uniform Initialization should not be thought of as a replacement for the old style constructor syntax.
And my reasoning is this:
If two statements don't have the same kind of intention, they shouldn't look the same. There are two kinds of notions of object initialization:
1) Take all these items and pour them into this object I'm initializing.
2) Construct this object using these arguments I provided as a guide.
Examples of the use of notion #1:
struct Collection
 int first;
 char second;
 double third;
Collection c {1, '2', 3.0};
std::array a {{ 1, 2, 3 }};
std::map m { {1, '1'}, {2, '2'}, {3, '3'} };
Example of the use of notion #2:
class Stairs
 std::vector stepHeights;
 Stairs(float initHeight, int numSteps, float stepHeight)
 float height = initHeight;
 for (int i = 0; i < numSteps; ++i)
 height += stepHeight;
Stairs s (2.5, 10, 0.5);
I think it's a bad thing that the new standard allows people to initialize Stairs like this:
Stairs s {2, 4, 6};
...because that obfuscates the meaning of the constructor. Initialization like that looks just like notion #1, but it's not. It's not pouring three different values of step heights into the object s, even though it looks like it is. And also, more importantly, if a library implementation of Stairs like above has been published and programmers have been using it, and then if the library implementor later adds an initializer_list constructor to Stairs, then all the code that has been using Stairs with Uniform Initialization Syntax is going to break.
I think that the C++ community should agree to a common convention on how Uniform Initialization is used, i.e. uniformly on all initializations, or, like I strongly suggest, separating these two notions of initialization and thus clarifying the intention of the programmer to the reader of the code.
Here's yet another reason why you shouldn't think of Uniform Initialization as a replacement for the old syntax, and why you can't use brace notation for all initializations:
Say, your preferred syntax for making a copy is:
T var1;
T var2 (var1);
Now you think you should replace all initializations with the new brace syntax so that you can be (and the code will look) more consistent. But the syntax using braces doesn't work if type T is an aggregate:
T var2 {var1}; // fails if T is std::array for example

If you have "" your code will be difficult to understand regardless of syntax. – kevin cline Dec 18 '12 at 17:21
Besides IMO it is the duty of your IDE to inform you what type it is returning (e.g. via hovering). Of course if you don't use an IDE, you took the burden upon yourself :) – abergmeier Dec 22 '12 at 11:44
_USER_ I agree with some parts of what you say. However, in the same spirit as the auto vs. explicit type declaration debate, I'd argue for a balance: uniform initializers rock pretty big time in template meta-programming situations where the type is usually pretty obvious anyway. It will avoid repeating your darn complicated -> decltype(....) for incantation e.g. for simple oneline function templates (made me weep). – sehe Dec 26 '12 at 23:50
_USER_ I thoroughly agree with your points, there is currently no agreed industry best practice for auto and uniform initialiasation, new language features are generally misused at first and the pain that causes is what informs best practice, Nicol Bolas' answer advocates a far too liberal approach to these new language features in my opinion. Good response highlighting real problems with using his approach. – radman Mar 8 '13 at 23:07
"But the syntax using braces doesn't work if type T is an aggregate:" Note that this is a reported defect in the standard, rather than intentional, expected behavior. – Nicol Bolas Mar 10 '13 at 0:40
add comment
If your constructors merely copy their parameters in the respective class variables in exactly the same order in which they are declared inside the class, then using uniform initialization can eventually be faster (but can also be absolutely identical) than calling the constructor.
Obviously, this doesn't change the fact that you must always declare the constructor.

We usually think of this water, which drains from our dishwaters, showers, and, yes, toilets, as carrying just filth — but it also flushes a great deal of heat from homes and businesses. In cold months, sewage is about 60 degrees, and in summer it can exceed 75 degrees, reports Andrew Maykuth of the Philadelphia Inquirer.
And why let that heat go to waste? To avoid doing so, Philadelphia-based NovaThermal Energy launched its first US pilot project in Philadelphia on April 12 that will harvest heat from still-warm sewage to heat buildings.
The technology is essentially a geothermal heat pump that extracts and concentrates heat as the sewage travels through the pump. In the winter, pipes carry this heat through the walls of buildings; in the summer, another set of pipes carries the heat away.
The critical piece of NovaThermal's tech is primarily scatological: the company holds a patent on a filtering device that removes — ahem — "larger debris" that could damage the pump from entering the system.
NovaThermal Energy already has its "wastewater geothermal energy" units installed in China, where they power the Southern Beijing Train Station and the municipal building for the province of Shanxi, among other buildings. And they plan to launch projects in New Jersey and Texas within the year.

The High Mountain Habitats
The mountain heights of Wales may seem an
inhospitable environment, but there are some surprising species
that thrive amongst the crevices, ledges, rocks and scree slopes of
even our highest mountains.
Ledges and crevices
High mountain ledges and rock crevices are important places for
some of the rarest mountain plants, particularly where veins of
base-rich rock break the surface. Their inaccessibility to sheep
makes them a refuge for many plants with a sensitivity to
Such places include the tall-herb ledges, where the mineral-rich
water flushing through them and the shade of the north-facing
slopes create conditions suitable for species that would normally
be associated with woodland. In summer, these aptly named tall-herb
ledges can provide some of the most attractive and spectacular
displays of wild plants in the mountains. They often have the
appearance of hanging gardens, supporting plants with names such as
wild angelica, ladies mantle, globeflower and roseroot
Also well adapted to this mountain habitat are the
arctic-alpines – plants usually found in high Alpine mountains or
far north in the arctic. They are found here in Wales on the very
edge of their distribution, and include the Saxifrages, mountain
avens and moss campion.
Many of these species survive by growing in pockets of soil in
cracks and crevices. They are generally small and often hug the
rock by means of creeping stems, or by adopting a cushion shape to
minimise their exposure to strong winds. They survive in this
hostile environment because under gentler conditions they would
soon be overcome by competition from more aggressive species.
These plants would appear to be safe in their mountain refuges
but even they face challenges – from rising temperatures, acid
rain, overgrazing by sheep and the attentions of increasing numbers
of feral goats in parts of North Wales.
Scree slopes and summits
Another rocky habitat of the mountains occurs on scree slopes.
These distinctive landforms are widespread, reflecting the geology
of their parent cliffs. Where screes are unstable and acidic (the
most common type in Snowdonia), the vegetation is usually composed
of a pioneer community of parsley fern, with various mosses and
Extremes of wind and temperature on the summits of the higher
mountains mean that few plants can survive. Nevertheless, species
such as the stiff sedge and the hardy dwarf willow are virtually
confined to this high ground. The latter species is locally common
in montane heath communities in Snowdonia that are not too heavily
grazed. The small size of its stems and leaves initially give the
impression of a low-growing bilberry, but closer inspection reveals
it to be a tree in miniature.

Mephisto like you've never seen it before
In late 1917 the German Army produced 20 A7V Sturmpanzerwagen's which were deployed in combat the following year. Crewed with 18 men, the cumbersome war machines clambered into action in April 1918. The German tanks were engaged in actions at such places as Villers-Bretonneux, a small French village that was recaptured by Australian soldiers at the cost of 1,200 lives. The A7V's were involved in the first tank versus tank action.
Named Mephisto by its crew, this 30-tonne tank was part of an advance towards the French town of Amiens, resulting in the capture of VillersBretonneux and the temporary retreat of Allied forces. During the battle, Mephisto became stuck in a shell crater and was abandoned by its crew. It remained on the battlefield for months before troops of the 26th Battalion AIF, composed mainly of Queenslanders, regained lost ground and retrieved it, dragging the tank behind Australian lines under cover of darkness.
It was sent to Australia as a war trophy, arriving at Norman Wharf in June 1919 where it was towed by two Brisbane City Council steamrollers to the Queensland Museum, then located in Fortitude Valley. It remains the sole surviving A7V tank in the world.
Eventually Mephisto was shipped to Brisbane and preserved at Queensland Museum.

Complex.Phase Property
Gets the phase of a complex number.
Namespace: System.Numerics
Assembly: System.Numerics (in System.Numerics.dll)
public double Phase { get; }
Property Value
Type: System.Double
The phase of a complex number, in radians.
For a complex number a + bi, the phase is computed as Math.Atan2(b, a).
You can identify a complex number by its Cartesian coordinates on the complex plane or by its polar coordinates. The phase (argument) of a complex number is the angle to the real axis of a line drawn from the point of origin (the intersection of the x-axis and the y-axis) to the point represented by the complex number. The magnitude (represented by the Magnitude property) is the distance from the point of origin to the point that is represented by the complex number.
You can instantiate a complex number based on its polar coordinates instead of its Cartesian coordinates by calling the FromPolarCoordinates method.
To convert the phase from radians to degrees, multiply it by 180/Math.PI.
The following example uses the FromPolarCoordinates method to instantiate a complex number based on its polar coordinates, and then displays the value of its Magnitude and Phase properties.
using System;
using System.Numerics;
public class Example
 public static void Main()
 Complex c1 = Complex.FromPolarCoordinates(10, 45 * Math.PI / 180);
 Console.WriteLine("{0}:", c1);
 Console.WriteLine(" Magnitude: {0}", Complex.Abs(c1));
 Console.WriteLine(" Phase: {0} radians", c1.Phase);
 Console.WriteLine(" Phase {0} degrees", c1.Phase * 180/Math.PI);
 Console.WriteLine(" Atan(b/a): {0}", Math.Atan(_URL_.Real));
// The example displays the following output:
// (7.07106781186548, 7.07106781186547):
// Magnitude: 10

A Brock University professor, a physician and a bracing specialist are teaming up on research to expand our knowledge of bone strength as well as re-think how we design back braces for people with scoliosis.
And they're inviting women across the Niagara peninsula to take part in the project.
The researchers are seeking young women, aged 18-30 years, who have or have had scoliosis, and who used a scoliosis brace during their adolescence. Scoliosis is a medical condition characterized by curvature and rotation of the spine.
Bareket Falk, a researcher in Brock's Department of Kineseology, is undertaking the project with partners Alan Rigby of the private-sector business Niagara Prosthetics and Orthotics, and Dr. Matt Greenway of the Michael DeGroote School of Medicine.
Falk said the researchers want to study how bracing may affect bone during the growing years, and whether flexible scoliosis braces are more effective than the rigid braces traditionally used by patients with scoliosis. Importantly, the researchers are interested in examining how nutrition and exercise can be used to alleviate some of the potential effects of bracing.

Whipped Cream Structure
The structure of whipped cream is very similar to the fat and air structure that exists in ice cream. Cream is an emulsion with a fat content of 35-40%. When you whip a bowl of heavy cream, the agitation and the air bubbles that are added cause the fat globules to begin to partially coalesce in chains and clusters and adsorb to and spread around the air bubbles.
Diagram of whipped cream structureAs the fat partially coalesces, it causes one fat-stabilized air bubble to be linked to the next, and so on. The whipped cream soon starts to become stiff and dry appearing and takes on a smooth texture. This results from the formation of this partially coalesced fat structure stabilizing the air bubbles. The water, lactose and proteins are trapped in the spaces around the fat-stabilized air bubbles. The crystalline fat content is essential (hence whipping of cream is very temperature dependent) so that the fat globules partially coalesce into a 3-dimensional structure rather than fully coalesce into larger and larger globules that are not capable of structure-building. This is caused by the crystals within the globules that cause them to stick together into chains and clusters, but still retain the individual identity of the globules. Please see a further description of this process for details. If whipped cream is whipped too far, the fat will begin to churn and butter particles will form.
Partially-crystalline Fat Globule, Partially-coalesced
Below are scanning electron micrographs image of whipped cream. If you compare the schematics above with the "real thing" below, you should be able to fully understand whipped cream structure.

As metropolitan Bangkok sprawls and expands, the boundaries of the nearby Dong Phayayen-Khao Yai (DPKY) Forest Complex and UNESCO World Heritage site are under increasing pressure. This project seeks to preserve the integrity of the UNESCO-mandated buffer zone between the Thai capital and the Forest Complex by transforming it into a vast agricultural testing zone.
Blanketed with rice paddies and dotted with agricultural laboratory buildings and schools, the buffer zone would become a testing field, focusing on studying and effectively producing food for Bangkok's growing population. The project imagines a form of bargain: the more productive this agricultural "laboratory," the more likely it is to remain an intact and effective protector of the World Heritage site it surrounds.

1) Hint to use with Like clause
If your SQL contain a LIKE clause then you could consider using a hint on the column where an index exists on this column.
Use the /*+index(table index_name) */ hint. The LIKE clause may prevent the use of the index. If the index is physically smaller than the table then it will likely be faster to use the index rather than the table.
Append only works with Insert into table1 select * from table2;
It really doesn't make sense for a single-row insert

text: The journal is fundamental to formal scholarly communication. This research reports highlights and preliminary findings from an empirical study of scholarly electronic journals. The purpose of the research is to assess the impact of electronic journals (ejournals) on scholarly communication, by measuring the extent to which they are being cited in the literature, both print and electronic. The intent is to provide a snapshot of the impact e-journals were having on scholarly communication at a given point in time, roughly the end of 1995. This study provides one measure of that impact, specifically on the formal, as opposed to informal, communication process. The study also examines the forms in which scholars cite e-journals, the accuracy and completeness of citations to e-journals, and practical difficulties faced by scholars and researchers who wish to retrieve e-journals through the networks.

Angelica is a tall biennial plant that acquired the name from its supposed ability to prevent or cure plague. People considered it a "guardian angel." All parts of the plant are aromatic. Use the leaves in salads, add the seeds as a flavoring in cooking, cook the roots as a vegetable and candy the stems. Essential angelica oil is used to flavor vermouth and Benedictine.
- More detailed information can be found in The Georgia Fruit & Vegetable Book
by Walter Reeves and Felder Rushing
- See also Home Garden Angelica
WHEN TO PLANT
Plant angelica in early spring, as soon as the worst of the freezing weather is over. It can tolerate frost but not temperatures that get down to the teens at night.
WHERE TO PLANT
This tall-growing herb needs room because it will reach 5 feet tall and spread 2 to 3 feet. Angelica prefers a location with light, moist soil that is in partial shade (filtered sun all day or shade part of the day). These plants fit equally well in a perennial border and the vegetable garden.
HOW TO PLANT
Buy started plants in the spring. Space the plants at least 2 feet apart in the garden in well-prepared soil. Usually, a couple of plants are sufficient for culinary needs. Since these are biennial plants, they flower the second year after planting and then die out. To have flowering plants each year, plant or sow seed each year. You may collect seeds in the fall and sow them immediately, or you may save seeds in an airtight jar in the refrigerator and sow them the following spring.
CARE AND MAINTENANCE
Control weeds until the plants are large enough to shade them out. Mulching is not recommended as weed prevention because of its potential to attract slugs. The plants prefer cool weather and moist soil; as with most aromatic herbs, these plants do better in soil with low fertility. Water angelica in dry weather. Giving them 1 inch per week is probably okay but too lush growing conditions cause overly tall, weak plants.
Harvest leaves as needed during the season. Pick pieces of fresh stem with the leaves for candying. At season's end, collect and dry the leaves. Harvest the seeds as they ripen in the flower heads. If flower heads are removed, these plants will last several years, growing as short-lived perennials. If the plant is allowed to flower and the seed is allowed to ripen on the plants and fall to the ground, angelica can become naturalized in the garden. Plant it where it can grow undisturbed by other gardening activities.

The new IFHE Digest 2019 has been published by The International Federation
of Hospital Engineering (IFHE). Our Development Manager Petri Pelkonen and Managing Director Timo Ohtonen have wrote an article: Important information about operating rooms and their electrical safety.
With this article, Mr. Ohtonen and Mr. Pelkonen wanted to point out the importance of insulation monitoring in saving lives and protecting valuable equipment in medical G2 premises. Actually Mr. Ohtonen wrote his first article about electrical safety in IFHE Digest in 2017. The article aroused much international interest towards electrical safety and insulation monitoring technology. He was surprised how little people knew about insulation monitoring in operating rooms.
Why the insulation monitoring is so important?
The leakage of electrical current can cause a fatal electric shock without any visible signs. It is difficult to prove it as a cause of death. Finnish authorities and hospital engineers are well aware of this risk. Finland has been a pioneer in the electrical safety of operating rooms. No operation will be performed in Finnish operating rooms if insulation monitoring is not in use. An insulation monitoring system has been mandatory in all operating rooms in Finland since 1980s.
The insulation level monitoring system functions like this:
1. The electric power network of the operating room is separated from electrical grid with a medical isolation transformer.
2. The insulation level monitoring system monitors all the electrical devices connected behind this transformer.
3. The equipment indicates the faults and problems before dangerous situations arise.
A residual-current device that switches the electricity off does not give a warning – insulation level monitoring is therefore needed
Electrical safety requirements set for operating rooms are observed in Finland. The insulation level monitoring system controls each socket and device. As soon as a problem occurs, the system gives an alarm before a dangerous situation arises.
In many countries, the situation is different. Operating rooms may only have a residual-current device that switches the electricity off when a device breaks down. That is not enough.
Electrical damages in operating rooms are an invisible danger that is not generally known. The purchase of equipment monitoring electrical safety would only constitute a small part of the overall costs of an operating room. Insulation level monitoring equipment may be operable for as long as 30 years. It may also be possible to install new generation equipment on top of an old system. It is noteworthy that the proactive monitoring system decreases technical work and ensures that operations are not interrupted. This brings significant cost savings.
Standards regulate electrical installations in medical facilities
The European and national standards regulate electrical installations and the operation of devices in medical facilities. Operating rooms are classified as G2 medical facilities. In Europe, these facilities require a specific IT system as well as monitoring equipment for the insulation space related to the IT system.
Safety brings savings
Besides safety, it all comes down to costs to a large extent. When problems are detected at an early stage, hazardous situations during operations can be prevented. This ensures that the operating room and equipment are efficiently deployed all the time and unnecessary downtime can be avoided. The personnel work more productively and the service life of surgical equipment is extended. This creates major cost savings.

More information: Otten, Pinto, Paffen, Seth & Kanai (in press). The Uniformity Illusion: Central stimuli can determine peripheral perception. Psychological Science
Four examples of the uniformity illusion with motion as an example.
- Open the video fullscreen.
- Keep your eyes fixated on the centre of the screen for a good amount of time (tens of seconds to minutes).
- In the first two examples the central stimuli are present from the start, in the latter two the central stimuli appear after a while. The first and the third example contain no fixation spot, the second and the fourth do. Some people find that the illusion works better without a fixation spot, but you can try out which works best for yourself.
- The fifth example is similar to the third, but now all the motion is much slower.
For more information, see the text below the examples.
In all examples the dots in the periphery rotate four times as fast as the central dots, but all dots seem to be going at the same speed after a while. When the central stimuli appear later (in the latter two examples), it leads, for some people, to a more dramatic effect. Now the peripheral stimuli abruptly appear to slow down. In the last example there can be some strange effects, because now the central motion is very slow. Again the peripheral motion is four times faster than the central motion. When the centre is empty, the periphery can be seen to move slowly and smoothly. However, when the central moving dots appear, the whole screen sometimes seems to become static. The peripheral motion can seem jerky at moments, as if it stops and goes.

This work reports the synthesis of NaCr2O4/GO nanocomposite using co-precipitation method for energy storage applications. Characterizations e.g., scanning electron microscopy (SEM) and X-ray diffraction (XRD) were performed to investigate the important optical and structural properties. The Crystalline size is seen to decrease from 28 nm for sodium chromite to 16.56 nm for nanocomposite NaCr2O4/GO. Raman results showed the existence of characteristic peaks for NaCr2O4/GO. Using cyclic voltammetry, the specific capacitance for NaCr2O4/GO was measured to be 455.5 F/g. The NaCr2O4/GO nanohybrids depicted significantly higher values of specific capacitance combined with extremely low charge transfer resistance, useful for various applications.

 A study has been made by clinical methods and by bio-assay of the effectiveness of a régime for prophylaxis against tetanus. The two principal objects of the method were to ensure that active immunization was offered to all patients who had received antitoxin and to measure the effect of the combined administration of toxoid and antitoxin.
 Because of a high incidence of failure to re-attend, 63·9% of patients requiring protection against tetanus would never have begun a course of active immunity unless toxoid had been given at the first attendance. The administration of antitoxin at the same time as the toxoid is given does not interfere with the latter's ability to provoke an immune response. A second injection of fluid toxoid produced a satisfactory immune response in 80·6% of subjects whose first dose had been given simultaneously with antitoxin.

Casting Time: 1 action
Components: V, S, M (a copper piece)
Duration: Concentration, up to 1 minute
For the duration, you can read the thoughts of certain creatures. When you cast the spell and as your action on each turn until the spell ends, you can focus your mind on any one creature that you can see within 30 feet of you. If the creature you choose has an Intelligence of 3 or lower or doesn't speak any language, the creature is unaffected.
You initially learn the surface thoughts of the creature--what is most on its mind in that moment. As an action, you can either shift your attention to another creature's thoughts or attempt to probe deeper into the same creature's mind. If you probe deeper, the target must make a Wisdom saving throw. If it fails, you gain insight into its reasoning (if any), its emotional state, and something that looms large in its mind (such as something it worries over, loves, or hates). If it succeeds, the spell ends. Either way, the target knows that you are probing into its mind, and unless you shift your attention to another creature's thoughts, the creature can use its action on its turn to make an Intelligence check contested by your Intelligence check; if it succeeds, the spell ends.
Questions verbally directed at the target creature naturally shape the course of its thoughts, so this spell is particularly effective as part of an interrogation.
You can also use this spell to detect the presence of thinking creatures you can't see. When you cast the spell or as your action during the duration, you can search for thoughts within 30 feet of you. The spell can penetrate barriers, but 2 feet of rock, 2 inches of any metal other than lead, or a thin sheet of lead blocks you. You can't detect a creature with an Intelligence of 3 or lower or one that doesn't speak any language.
Once you detect the presence of a creature in this way, you can read its thoughts for the rest of the duration as described above, even if you can't see it, but it must still be within range.

You see that '(a b (c d) e) is a tree, don't you? Something like
In this representation, nodes are lists, and leafs are symbols. What you could do, it print all the leafs of the tree:
 1. if the tree is empty (= is the empty list), then stop
 2. If the tree is not empty, then
 1. If the tree's CAR is a symbol, print it, then process the CDR of the tree
 2. If the tree's CAR is a list, process the CAR of the tree, then process the CDR o the tree
Once you do that, you'll replace "print" by "put the value somewhere". Hopefully, that should lead you to what you want.

Triangle of reference
From Wikipedia, the free encyclopedia
Jump to: navigation, search
The triangle of reference (also known as the triangle of meaning[1] and the semiotic triangle) is a model of how linguistic symbols are related to the objects they represent. The triangle was published in The Meaning of Meaning (1923) by Ogden and Richards.[2] While often referred to as the "Ogden/Richards triangle" the idea is also expressed in 1810, by Bernard Bolzano, in his Beiträge zu einer begründeteren Darstellung der Mathematik. However, the triangle can be traced back to the 4th century BC, in Aristotle's Peri Hermeneias (often referred to in its Latin translation De Interpretatione, second book of his Organon). The Triangle relates to the problem of universals, a philosophical debate which split ancient and medieval philosophers (mainly realists and nominalists).
The triangle describes a simplified form of relationship between the speaker as subject, a concept as object or referent, and its designation (sign, signans). For more elaborated research see Semiotics.
Ogden semiotic triangle.png
Interlocutory applications[edit]
Other triangles[edit]
The relations between the triangular corners may be phrased more precisely in causal terms as follows[citation needed][original research?]:
 1. The matter evokes the writer's thought.
 2. The writer refers the matter to the symbol.
 3. The symbol evokes the reader's thought.
 4. The reader refers the symbol back to the matter.
The communicative stand[edit]
Such a triangle represents ONE person, whereas communication takes place between TWO (objects, not necessarily persons). So imagine another triangle and consider that for the two to understand each other, the content that the "triangles" represent must fit or be aligned. Clearly, this calls for synchronisation and an interface as well as scale among other things. Notice also, that we perceive the world mostly through our eyes and in alternative phases of seeing and not seeing with change in the environment as the most important information to look for. Our eyes are lenses and we see a surface (2D) in ONE direction (focusing) if we are stationary and the object is not moving either. This is why you may position yourself in one corner of the triangle and by replicating (mirroring) it, you will be able to see the whole picture, your cognitive epistemological and the ontological existential or physical model of life, the universe, existence, etc. combined.[citation needed][original research?]
Direction of fit[edit]
Main article: Direction of fit
John Searle used the notion of "direction of fit" to create a taxonomy of illocutionary acts. [3] [4]
World or
or Word
 Writer's THOUGHT retrieves SYMBOL suited to REFERENT, Word suited to World.
 Reader's THOUGHT retrieves REFERENT suited to SYMBOL, World suited to Word.
Actually the arrows indicate that there is something exchanged between the two parties and it is a feedback cycle. Especially, if you imagine that the world is represented in both persons' mind and used for reality check. If you look at the triangle above again, then remember that reality check is not what is indicated there between the sign and the referent and marked as "true', because a term or a sign is allocated "arbitrarily'. What you check for is the observance of the law of identity which requires you and your partner to sort out that you are talking about the same thing. So the chunk of reality and the term are replaceable/interchangeable within limits and your concepts in the mind as presented in some appropriate way are all related and mean the same thing. Usually the check does not stop there, your ideas must also be tested for feasibility and doability to make sure that they are "real" and not "phantasy". Reality check comes from consolidating your experience with other people's experience to avoid solipsism and/or by putting your ideas (projection) in practice (production) and see the reaction. Notice, however how vague the verbs used and how the concept of a fit itself is left unexplained in details.[editorializing]

-term student outcome metrics. Fifty percent of Hypothetical U. enrollments are underserved students; the team anticipates that they will see the most improvement in gateway course achievement with this group given the focus of their activities, and expects slight improvement for other students. Hypothetical U. reviewed results from other institutions evidencing significant course outcome improvements when faculty have and act on real-time information about students, and for underserved students when course content is relatable for students from diverse backgrounds. From others' experiences, Hypothetical U. is optimistic about its ability to influence significant gains in gateway completion, particularly for underserved students. Their near-term target statements follow.
- The gap in the gateway math course success rate (achieving a C or better) between underserved and other students will decrease from 10 to 5 percentage points in the spring 2021 semester, with no decline in achievement by other students (Figure 2).
- Of all students attempting, the percentage of students successfully completing gateway math (achieving a C or better) will increase from 30 to 36 percent in the spring 2021 semester.
Examining historical data, and the relationship between gateway math completion rates across student populations, Hypothetical U. estimated the improvement in retention rates and set their long-term targets using the estimation model below (see Figure 3). This relatively simple model makes a number of assumptions – steady enrollments and composition of students, similar retention patterns over time, and a very limited number of influences on students and the environment – but provides campus teams with an example for determining "how much" is possible.
- Compute the number of additional students who will complete gateway math if the Spring 2021 target is hit. So, 25% of 2,500 historically underserved students completed gateway math in the base year, or 625 students.
- At a target of 33%, this increases to 825 students, for an additional 200 historically underserved students completing gateway math.
- Assuming a retention rate for the target that is similar to the base year—or 60% for historically underserved students—compute the number of additional students that will be retained: 60% of 200, or 120 students.
- Add the 120 additional students to the base of 1,500 retained students, for a total 1,620 historically underserved students retained.
- Compute the target percent, or 1,620 of 2,500 historically underserved students retained, or 65%.
Looking forward to evaluating the near-term metrics every term, Hypothetical U. decided it was prudent to begin evaluating their long-term target after completing one academic year of their new activities to provide sufficient time for students to attempt their gateway math course, and for faculty to revise curriculum. This resulted in Hypothetical U.'s formal target statements for the retention long-term metric:
- The percentage of first-time students retained will increase from 64 to 67 percent for the 2021 entering cohort, as measured by retention to their second academic year.
- The retention equity gap for first-time students will decrease by three percentage points for the 2021 entering cohort, as measured by retention to their second academic year.

An immigrant who is considered an "outstanding researcher or professor" may qualify for a EB-1B visa. The immigrant must be internationally acclaimed in his/her scientific or scholarly field of work.
Unlike EB-1A Visas, EB-1B immigrant visas must be employer sponsored meaning that the professor or researcher must have sponsorship from his/her employer throughout the petitioning process in order to receive a EB-1B Visa. Through the petition process, the employer becomes the petitioner and the immigrant receiving the EB-1B Visa is the beneficiary.
You must demonstrate international recognition for your outstanding achievements in a particular academic field. You must have at least 3 years' experience in teaching or research in that academic area. You must be entering the United States in order to pursue tenure or tenure track teaching or comparable research position at a university or other institution of higher education.
To be recognized internationally as an Outstanding Researcher or Professor in one's field requires at least two (2) of the following types of evidence:
- Evidence of receipt of major prizes or awards for outstanding achievement
- Evidence of membership in associations that require their members to demonstrate outstanding achievement
- Evidence of published material in professional publications written by others about the alien's work in the academic field
- Evidence of participation, either on a panel or individually, as a judge of the work of others in the same or allied academic field
- Evidence of original scientific or scholarly research contributions in the field
- Evidence of authorship of scholarly books or articles (in scholarly journals with international circulation) in the field
Applying for a EB-1B can be a grueling and involved process to provide enough evidence that you have been recognized internationally in your work. Be prepared for all situations by having a lawyer by your side. It is crucial to have an experienced professor and researcher visa immigration lawyer by your side to help you through the application process to make sure that you have met all the required criteria to be granted a EB-1B Visa.

One of the most difficult genealogical tasks you may face in researching your Italian roots is in tracing the ancestry of an Italian foundling.
Known in Italy as Trovatelli or Proietti, a foundling is a child abandoned at birth, for one reason or another. The most common is that the child was born out of wedlock, but others, such as; the family being to poor to care for another child, are not unheard of.
These infants were usually left at a foundling home. The foundling homes were a place where Italian women could legally abandon their children, with complete anonymity (although, often times, especially in small towns, the identity of at least the mother was generally known). Sometimes children were left with tokens to indicate their parentage, in the event the mother or father should ever want to reclaim them, although, this was rare.
After the child was abandoned, their birth would be registered in the Stato di Civile, under a name the mayor or other town official would give the child. These names were made up by the town official, some of the names were unique (such as one I have in my ancestry, Clemanni), others were generic names given to many foundlings, such as; Esposito (literally meaning "exposed").
After the infant's birth was registered, they were placed in the care of a woman who recently had given birth to a child (usually one that had recently lost a child). These women were called, wet nurses. The roles these women had in the child's life varied greatly. Some took the child in, simply to collect money given to them by the town to care for the child, others treated them as their own, sometimes even giving the child their own surname.
Often times, family lore and myths existed about the child's parents. A common one is that the foundling was the child of a nobleman. These stories, while not always untrue, can stem from a variety of sources. One being that the mother made the claims while pregnant (to dignify to some extent something that was a social taboo at the time). Secondly being that when the child was born, he/she was given a name by the town official, that sounded "noble" (Della Luna, for instance). Whatever the case, while these stories are fun to think about, always take them with a grain of salt.
Birth records for foundlings can be found in the Registri dello Stato Civile, Atti di Nascita (birth acts) of the child's town of origin, usually in Parte II. These records rarely give the parents names (as previously stated, their identity was to be kept secret if they chose it to be).
If his or her parents recognized the child, these records can usually be found in the Atti Diversi (Misc. acts) for the year of the child's birth.
Other records that can help you in tracing your foundling ancestor's genealogy are marriage records and baptism records. Marriage records would be found in the Registri dello Stato Civile, Atti di Matrimonio (marriage acts), whereas baptism records (battesimo) are maintained by the church where he/she was baptized, and can be hard to obtain.
Again, tracing the ancestry of a foundling can be incredibly difficult, and sometimes, impossible, so to familiarize oneself with the common procedures that took place is very important. Foundling history in Italy is complex, and I couldn't begin to go through all the variables in one post. This is just an attempt to help you understand the general process. A valuable resource for further research is the book 'Sacrificed for Honor: Italian infant abandonment and the politics of reproductive control' by David I. Kertzer.

There are many different people in the world; fat and thin, polite and impolite, cheerful and gloomy etc. So we will star to talk about tall people and advantages and disadvantages of being tall
Tall people could bump one's head against anything which is lower than they are. For example a bar in the bus or a chandelier if it too low. They couldn't wear whatever they want because they often couldn't find their size of clothes in shops. Fortunately there are some specialized shops with clothes for tall people. And if it rains they always have wet legs because their umbrella is too high. So that was disadvantages. And what about advantages?
Tall people can do some sports which are very difficult to do for short people. For example basketball, volleyball, high jump etc. They can reach that things that anyone else couldn't so they do not need to ask the shop assistant to put the goods from the highest shelves. And tall people seem to be strong so they are respectable.
