There is an old dry well. Its sides are made of concrete rings. Each such ring is one meter high, but the rings can have different (internal) diameters. Nevertheless, all the rings are centered on one another. The well is N meters deep; that is, there are N concrete rings inside it. You are about to drop M concrete disks into the well. Each disk is one meter thick, and different disks can have different diameters. Once each disk is dropped, it falls down until:
- it hits the bottom of the well;
- it hits a ring whose internal diameter is smaller then the disk's diameter; or
- it hits a previously dropped disk. (Note that if the internal diameter of a ring and the diameter of a disk are equal, then the disk can fall through the ring.)
The disks you are about to drop are ready and you know their diameters, as well as the diameters of all the rings in the well. The question arises: how many of the disks will fit into the well?
Write a function: int falling_disks(int A, int N, int B, int M); that, given two zero-indexed arrays of integers − A, containing the internal diameters of the N rings (in top-down order), and B, containing the diameters of the M disks (in the order they are to be dropped) − returns the number of disks that will fit into the well. For example, given the following two arrays:
A = 5 B = 2 A = 6 B = 3 A = 4 B = 5 A = 3 B = 2 A = 6 B = 4 A = 2 A = 3
the function should return 4, as all but the last of the disks will fit into the well. The figure shows the situation after dropping four disks.
- N is an integer within the range [1..200,000];
- M is an integer within the range [1..200,000];
- each element of array A is an integer within the range [1..1,000,000,000];
- each element of array B is an integer within the range [1..1,000,000,000].
- expected worst-case time complexity is O(N);
- expected worst-case space complexity is O(N), beyond input storage (not counting the storage required for input arguments).
- Elements of input arrays can be modified.
I tried using a stack and doing something, but i am not able to get to O(n) solution, the worst case still remains O(n^2) even after some optimizations i think.

Tools - DIF-Pack
DIF analyses can and indeed should be used to ensure that assessment items and tests are fair, in particular equally valid for various specified examinee subgroups, such as males and females. The DIF-Pack includes both source code and executable code for SIBTEST, POLY-SIBTEST, and Crossing SIBTEST, which together can test variously scored items and bundles of items (a bundle viewed as a collection) for various kinds of DIF. The source code is provided to facilitate continued improvement of the software, including applications to non-standard settings, research projects, improvements to the statistical algorithms, etc.
SIBTEST - Assessing Differential Item/Bundle Functioning (DIF/DBF)
SIBTEST implements a nonparametric estimation and hypothesis testing statistical method of assessing DIF in one or more items and/or DBF in one or more bundles of items. The method is based on Shealy-Stout's (1993) multidimensional IRT model for DIF, a model further developed by Roussos and Stout (1996). The model assumes that examinees matched on the level of the latent ability the test is designed to measure may differ in their expected performance on an item or on an item bundle because of construct irrelevant sources of score variation, and as such DIF may occur. This desired matching of examinees on the latent target ability that the test is intended to measure is done approximately by matching examinees either on total test score or on a user-specified subscore believed to validly measure the target ability over the studied examinee subpopulations. The total score except for certain items being removed that are believed to be possibly DIF-producing is a common and sound matching choice. With a flexible âuser-friendlyâ front-end program the user specifies the particular DIF/DBF hypothesis tests she wishes to perform, including:
- which item(s) or item bundle(s) will be tested for DIF/DBF,
- the alternative hypothesis to be tested: either a one-sided hypothesis of DIF/DBF against the reference group, a one-sided hypothesis of DIF/DBF against against the focal group, or a two-sided hypothesis of DIF/DBF against either group, and
- which items will be used to construct the examinee matching score.
SIBTEST uses a sophisticated nonlinear regression correction procedure (Jang & Stout, 1998) to match examinees, a procedure that has demonstrated improved effectiveness in controlling the false positive flagging of non-DIF items in comparison to the original linear regression correction in Shealy and Stout (1993).
Crossing SIBTEST tests for crossing DIF/DBF, the condition in which the DIF/DBF is experienced by one group for lower values of ability level and by the other group for higher levels of ability. In this manner, DIF against both specified examinee populations is possible in a single item, occurring as a function of ability level. Analogous to SIBTEST, this program uses a regression correction technique to appropriately match examinees from the two populations, and computes the expected score differences for a suspect item or item bundle at varying ability levels. A strength of the procedure is its capacity to identify the location of the crossing point (e.g., the target ability level at which the expected score difference changes sign). Output includes an estimate of the amount of crossing-DIF present, the point at which such crossing occurs, the relative amount of the total amount of crossing DIF/DBF occurring against each population (necessary because crossing DIF consists of DIF against both populations depending on ability level), and the results of the DIF/DBF tests of significance. The Crossing SIBTEST procedure is also sensitive to the more commonly occurring unidirectional DIF/DBF, although the hypothesis testing statistical procedure differs some in algorithmic detail from regular SIBTEST.
Polytomous SIBTEST handles polytomously scored item responses (ordered responses with more than two response categories). This extension of SIBTEST is conceptually straightforward, except for some changes required to account for the additional ordered item score categories in the matching criterion. It uses a revised reliability estimate in performing the regression correction, which controls for too many DIF/DBF false positives. This regression correction is a generalization of the original linear regression correction of Shealy and Stout (1993).

Image of the Eleazer Arnold House, built c. 1687, located in Lincoln, RI.
In 1693, Eleazer Arnold, a major landowner, built his house along Great Road, one of the earliest roads in the colonies. Two stories high, with a pilastered chimney, the home so dominated the modest dwellings of nearby farmers that it earned the title "Eleazer's Splendid Mansion." With its massive chimney end wall, the house is a rare survivor of a once-common Rhode Island building type known as a stone-ender. The structure has sustained many alterations over the centuries. Visitors find evidence of seventeenth-century construction methods, eighteenth-century additions, nineteenth century graffiti, and the twentieth-century approach to preservation that restored the house to its present appearance.

 Bad Good


Tantrum Tracker
Tantrum Tracker is a handy way to keep a record of your children's good or bad behavior for discussion at a more convenient time. The date and time are recorded automatically while you input the location and observed behavior with reminder notes. You award or remove stars or half-stars that you and your child have agreed upon as a desired reward. Tantrum Tracker may be used for as many as nine children. There are no in-app purchases available or add-ons required for the full use of this app. It won't track any information about you or your children - it simply takes the information you enter and stores it in an internal database.
Here's how Tantrum Tracker works:
Little Jimmy threw a fit in Walmart because he couldn't get the latest junky toy that he managed to set his sights on. You want to keep track of his improper behavior but with two other kids in tow, you quickly forget who did what. And by the time you get home, that fleeting thought of writing down the details of Jimmy's fit has long since vanished from your frazzled mind.
Does this sound familiar? Well, that's where the Tantrum Tracker app steps in and allows you to record the details of that fit on your Android phone when it happens so it will be noted for later use. Tantrum Tracker also records good behavior so it can be used to keep track of your child's progress toward an agreed-upon goal.
Sit down with your child and decide what goal he or she wants (toy, special dinner, family outing, etc.) and determine an appropriate number of stars needed to reach that goal. Then simply enter that information into Tantrum Tracker. Following each occurrence of good or bad behavior, use Tantrum Tracker as a quick note-taker to add or remove stars as indicated by the situation and to take notes on the particular behavior.
For additional information, including complete page-by-page screenshots, please visit our website:
Tantrum Tracker Features:
1) Keeps track of up to nine children
2) Date and time of behavior is entered automatically
3) Parent inputs location, description of behavior and number of stars given or taken away
4) Visual display of stars and goal so child can easily see his or her progress
5) No advertising of any sort
6) No in-app purchases offered or required for full app use
7) Secure - absolutely no location tracking or "calling home"
8) Internet use needed only for access to the Home, Help and Legal Stuff pages of the Tantrum Tracker website
Other Possibilities:
1) Reward and track your child's progress during potty training
2) Provide a goal for your child to do better in school
3) Encourage your partner to take out the garbage or perform other household tasks
4) Other uses are limited only by your imagination

Radiant power from the images of adjacent point sources will spill over into each other even though their separation is greater than the system resolution element. This spillover or system optical crosstalk can be troublesome if a point source of interest is in the vicinity of a much brighter point source. A method is presented for computation of the constituent of system optical crosstalk due to optical surface scatter. This analysis provides the scatter function at the image based on the scatter function for each surface and the surface position along the optical path.

Why does She Summits exist?
We exist to awaken and activate the untapped potential within those who identify as female to create conscious change in the world.
What is She Summits?
She Summits is a community festival that focuses on the contributions of those who identify as female to important social and environmental conversations through movement-based films, workshops and events.
How does She Summits do this?
She Summits connects to the head and to the heart of our community. By creating awareness and educating on critical issues and through emotionally connecting with the heart, we activate the passion needed for change.
We want those who identify as females to feel that they have the ability to act independently and make their own free choices. When you combine awareness and agency, we believe we will experience a more harmonious world for all and with Mother Earth.
Our community is composed of all genders and is multi-generational. We believe that the conversations we have at She Summits are for all to have and when our community works together, more female-identifying people will be empowered to take action where their passion lies.
We're committed to raising awareness around environmental issues and helping those who identify as females connect more deeply with Mother Nature, for when those who identify as females care about the environment and feel a sense of agency within themselves, they will make positive change.
Movement differs for everyone and especially across the globe. It's important for us to acknowledge the many forms of movement that exist in the world because with this, we become awakened to ideas that may activate change.
When education is combined with present-moment awareness, we believe that better decisions will be made to serve those in our world and Mother Earth herself.

Dry reforming of methane is one of the key reactions to exploit natural gas feedstocks by their catalytic conversion to synthesis gas (CH4 + CO2 → 2H2 + 2CO), which is used in the production of transportable liquid fuel. However, this reaction suffers from thermodynamic conversion limits and high thermal energy requirements. Herein we report that a SrTiO3-supported rhodium (Rh/STO) catalyst efficiently promotes methane reforming under ultraviolet light irradiation without heat supply at low temperatures, which cannot be achieved by conventional thermal catalysis. The photoexcited holes and electrons are used for CH4 oxidation over STO and CO2 reduction over rhodium, respectively. Isotope analysis clarified that the lattice oxygens (O2−) act as mediator to drive dry reforming of methane. The materials design of Rh/STO can be extended in principle to diverse uphill reactions that utilize photon energy to obtain valued products from different carbon resources.

Can we use autonomous wheelchairs for elderly persons with deteriorated physical and cognitive functions so that they can enjoy walking?
Walking is recommended for elderly persons in order to maintain good health. However, it is true that walking accidents involving elderly persons frequently. Family and the caregiver may go with them to secure their safety, but the elderly regret having to ask someone to help them take a little walk or run an errand.
How can the elderly enjoy walking alone as much as they like without causing a burden on the family and caregiver?
How about a wheelchair driven by automated driving technology that goes with elderly persons when they walk?
The wheelchair is not intended to take elderly persons to a desired destination, but to accompany them when they take a walk, and can take them to the destination if they become tired. The wheelchair recognizes and averts danger during the walk, and thus protects the elderly user. At the same time, it fulfills the desire of the elderly "to walk as much as they want," and gives the family and caregiver a sense of security in that "it is OK for them to go out."
If a wheelchair accompanies elderly persons on a walk and gives them a ride when they return home, it may expand the range of walking activity to a great extent. The wheelchair giving them a ride mitigates physical and cognitive concerns, and may encourage to walk further. The expanded range of activity also expands the range of socialization. It may make it easier to see old friends.
When the family and caregiver share information about the location and status of the wheelchair, and confirm the safety of an elderly person from a distance, they can send the elderly person out reassuringly. Once the elderly no longer impose any burden on the people around them when they go out, they become confident in doing so and may go out more frequently.
This is a result of a research for Japan METI's R&D and PoC of smart mobility system: a study of autonomous driving and its social values and use scenarios. (2016)

The history of Federalism in Nigeria can be traced to the division of the country into three provinces (Northern Province, Western Province and Eastern Province) by Governor Bernard Bourdillion in 1939. Governor Bernard Bourdillion (1935 – 1943) recommended the replacement of the provinces by regions which Arthur Richard's Constitution later implemented in 1946. It was the idea of the Richard's constitution that brought in a Federal structure but which it didn't accomplish to the end. However, in 1953, Governor Macpherson's constitution improved on that of Richard's by creating House of Rep. with powers to make law for the country and Regional Houses of Assembly to make law for the regions. Later, in 1954, the Lyttleton constitution came in with a Federal system of government for the country. This was as a result of the constitutional conference that was held in London in 1953 (1953 London Constitutional Conference) where it was decided that Nigeria should become a Federal State.
Federalism is a system of government whereby power is constitutionally shared between the central government and other component units e.g. State/region and local government, but in 1954 there were only the central and regional government in Nigeria. Their powers and functions were shared to them by the constitution. Exclusive legislative functions were meant for the central government while concurrent legislative functions were meant for both the central and regional government and residual legislative functions were meant for the regions.
Here are some reasons why Federalism was introduced into Nigeria.
* Cultural diversity
* Fear of domination by the minorities
* The size of the country
* Geographical factor
* Bringing government nearer to the
*British colonial policy
* Economic factor
* Effective administration.

A New Power: Photography in Britain 1800–1850
The announcement of photography's invention in January 1839, first in Paris and then in London, introduced a 'new power' into British life. This new power – derived from photography's capacity to automatically capture the images created in a camera – was soon being used for every conceivable purpose.
A New Power: Photography and Britain _PHONE_ explores the early history of photography, starting with the invention of the medium and the earliest dissemination of photographic images in Britain and ending with the famous Great Exhibition of 1851. It examines the broad range of uses that photography would quickly come to fill, from documenting the invention of celebrity to the very first 'travel photography' and how this helped to shore up colonial sensibilities.
By showing how photography intersected with all aspects of a nascent modernity, A New Power reveals photography's crucial role in making Britain the society it is today.

Today's tutorial is an in-depth overview of how to use the Up To Replenishment method for purchasing. Up To is one of the most common Advanced Forecasting methods in Prophet 21.
What is an Up To Item in P21?
There are four main calculations that make up the Up To Replenishment method in Prophet 21.
- Order Point: Lead time, Review Cycle, and Safety Stock all factor heavily into the calculations for Order Point.
- Order Quantity: The calculations for Net Stock and Order Point both factor into this final calculated number.
- Required Units: This fourth calculation only applies to a purchasing unit of measure with a different unit size or a case of items.
We have already done an in-depth tutorial on the first calculation, Net Stock (learn about Net Stock here). This training focuses on the other three calculations in the Up To Replenishment method: Order Point, Order Quantity, and Required Units.
How to Calculate Order Point:
Order Point adds your Lead Time Days, Review Cycle Days, and Safety Stock Days into one number. The calculation then multiplies that number by the Daily Usage.
- Daily Usage: The Forecast Usage for the next month is divided by the calendar days of the month you run it in.
- Lead Time Days are either the Calculated Lead Time or Published Lead Time on the item.
- Review Cycle is how often you look at this item or product line. This video tutorial covers where you can set Review Cycle and explains the factors that control it.
- Effective Safety Stock Days for this item are set to thirty straight days. This video tutorial explains Safety Stock Days and how to set them in Prophet 21.
Example: Add 45 (Lead Time Days) + 14 (Review Cycle Days) + 30 (Safety Stock Days) together. That combined number is multiplied by the Daily Usage for a Calculated Order Point of 376.
- When you move to the bottom of the Order Point calculation, you will find the MAX calculation. Right beside the MAX is an Item Order Point (in this example, the Item Order Point is 100).
- Item Order Point is the manual Order Point (or Min) on an item.
- This function takes the Max (The greater of the two numbers—in this case, the calculated Order Point) and moves it further down through the calculation.
How to Calculate Order Quantity:
Order Quantity has several different factors that play into the calculation.
- The first calculation is the Max.
- This calculation takes your listed Period Usage (your forecast usage) and multiplies it by the set minimum Periods to Supply (months in this instance).
- ABC Class is an important factor that affects the Periods To Supply number.
Example: The Max Calculation takes the listed Period Usage of _PHONE_ and multiplies it by three (months) Periods to Supply and gets a result of 393.
- The second calculation works with the Max and the Order Point we got in the previous calculations (in this case, the Calculated Order Point).
- The Max shows that the Order Quantity is based on whichever is the greater number between Periods To Supply or Order Point. That number will move down to the final part of this calculation.
Example: Since the Calculated Order Point is the greater number, the value of 393 moves down. And to the right, it subtracts the Net Stock value found in the very first calculation. The final Order Quantity of 250 is then populated on the far left of this screen.
How to Calculate Required Units:
The three main calculations for the Up To Method are the Net Stock, Order Point, and Order Quantity. There is also a chance for a fourth calculation though.
If your preferred purchasing method was a CASE of individual eaches, you would have a final calculation for Required Units.
The first calculated number would be divided by the unit size, which would tell you what your required units were.
Example: If I had ten items in a case, and my Order Quantity was the 250 we calculated above, I would order twenty-five cases.
However, the Required Units calculation does not apply in our previous examples because the required units were in Each or EA.
The Up To method is a little bit more complicated than Min Max, but it is an incredibly useful process to know. I probably have about a million monthly conversations with Atlas P21 customers about it.
You simply need to understand how Lead Time, Review Cycle, Safety Stock, even the manual Min (Order Point), and of course, Net Stock, which is the base of all these purchasing methods play into this calculation. And Prophet 21 does an excellent job of breaking down the formulas on the screens.

how to get value from the textblock, which is present in listbox....
here is the code xaml :

share|improve this question

1 Answer
You don't get the value directly from the TextBlock.
Instead what you do is bind the SelectedItem to a property on your viewmodel. To get the value of the TextBlock directly would violate the priciples of MVVM (if you are using that pattern). The viewmodel presents the data, it has no clue how that data is being rendered to the UI. IOW it has no idea there are three TextBlocks.
 ... etc...
This means that every time the selected item is changed, the new value will be populated into the bound property on the viewmodel. All you have to do then is access that object - it's as easy as that. This means you may also possibly be able to get rid of your SelectionChanged event hookup, depending on what it is doing.
However if you insist on getting the instance of the template used to present any particular data item in a list control, then this is the way to do it programmatically:
This will return you the StackPanel and its contents, you can then either use FindName() or just enumerate the child controls to find the one you are interested in.
FrameworkElement element = myListBox.ItemContainerGenerator.ContainerFromItem(myDataItem) as FrameworkElement;
if (element!= null)
 FrameworkElement child = element.FindName("myChildName");

text: This study investigated the influence of top-down and bottom-up information on speech perception in complex listening environments. Specifically, the effects of listening to different types of processed speech were examined on intelligibility and on simultaneous visual-motor performance. The goal was to extend the generalizability of results in speech perception to environments outside of the laboratory. The effect of bottom-up information was evaluated with natural, cell phone and synthetic speech. The effect of simultaneous tasks was evaluated with concurrent visual-motor and memory tasks. Earlier works on the perception of speech during simultaneous visual-motor tasks have shown inconsistent results (Choi, 2004; Strayer & Johnston, 2001). In the present experiments, two dual-task paradigms were constructed in order to mimic non-laboratory listening environments. In the first two experiments, an auditory word repetition task was the primary task and a visual-motor task was the secondary task. Participants were presented with different kinds of speech in a background of multi-speaker babble and were asked to repeat the last word of every sentence while doing the simultaneous tracking task. Word accuracy and visual-motor task performance were measured. Taken together, the results of Experiments 1 and 2 showed that the intelligibility of natural speech was better than synthetic speech and that synthetic speech was better perceived than cell phone speech. The visual-motor methodology was found to demonstrate independent and supplemental information and provided a better understanding of the entire speech perception process. Experiment 3 was conducted to determine whether the automaticity of the tasks (Schneider & Shiffrin, 1977) helped to explain the results of the first two experiments. It was found that cell phone speech allowed better simultaneous pursuit rotor performance only at low intelligibility levels when participants ignored the listening task. Also, simultaneous task performance improved dramatically for natural speech when intelligibility was good. Overall, it could be concluded that knowledge of intelligibility alone is insufficient to characterize processing of different speech sources. Additional measures such as attentional demands and performance of simultaneous tasks were also important in characterizing the perception of different kinds of speech in complex listening environments.

The Budgerigar, also known as the Common Pet Parakeet, Shell Parakeet or by its nickname the Budgie, is native to Australia. It inhabits scrublands, open woodlands and grasslands. Under favourable conditions these birds form flocks of thousands of individuals. Since they eat seeds and therefore will predate on farm crops such as wheat they are considered by many farmers to be pests.
In the wild the Budgerigar is green and yellow. Captive breeding has produced individuals that are blue, white, yellow or grey.
Budgerigar @ Safari Niagara
 - A large number of these birds call Safari Niagara home. You can visit them in their summer home and get up close and personal by feeding them.
Scientific Classification
Species:Melopsittacus undulatos
Did you know?
 - A feral population of Budgies has been recorded since the 1940's in St. Petersburg, Florida. The birds are now less common due to competition from introduced starlings and English house sparrows.

Before farmers go full throttle into the 2012 planting season, they would be wise to inspect what's left of their 2011 corn crop for signs of mold, says a Purdue University agricultural engineer.
Richard Stroshine said he has heard scattered reports of Indiana farmers finding higher-than-normal percentages of moldy, discolored kernels when they've removed corn from storage facilities. Elevators and other buyers of corn pay less for mold-contaminated grain, if they buy it at all.
Corn stored in bins since the fall harvest could be at a heightened threat for mold, Stroshine said. The reason? A winter that wasn't cold enough for long enough to protect the grain from fungal infection.
Moldy corn can contain toxins harmful - even fatal - to livestock. Much of the corn grown in Indiana is used as animal feed.
"Farmers should constantly be checking their grain for mold growth," Stroshine said. "If they find mold, they've got to get that corn out of the bin as soon as possible so that it doesn't spread to other grain in the bin."
A typical winter with air temperatures regularly near or below freezing allows corn to be cooled to temperatures near freezing, inhibiting mold development. That is particularly important when corn is stored at or above 15 percent moisture. This past winter saw many days above 50 degrees Fahrenheit, creating conditions more favorable for mold growth.
When mold risks are high, farmers should take steps to evenly cool the grain in the bin. A common practice, known as coring, involves taking one or more truckloads of corn from the bin and leveling the crop that remains. The process removes fine material that often accumulates in the center - or core - of the bin, filling air pockets between kernels and restricting air circulation.
To ensure even airflow distribution, farmers should maintain a level surface at the top of the bin. Without sufficient and uniform air movement in the bin, heat can build up in some areas and promote mold growth.
Farmers who cored their bins reduced the likelihood of mold problems this spring but still should keep an eye on their leftover crop, Stroshine said. Those who didn't perform coring operations will need to be even more vigilant, he said.
Bins should be visually inspected and grain temperatures monitored weekly, Stroshine said. He recommended running bin fans for 30 minutes before entering the storage facility to conduct an inspection.
"Aeration will push musty odors, which are indicative of mold growth, to the headspace of the bin," he said. "If the problems are deeper in the bin it will take longer for odors to reach the surface. So you could run the fans another 2-4 hours and check again.

PEVA is a biodegradable, non-chlorinated vinyl which is commonly used in shower curtains, plastic wrap for food and sports padding. It is also called polyethylene vinyl acetate, or ethylene vinyl acetate.
PEVA is a safe alternative to using PVC shower curtains that can give off many volatile organic compounds which can be toxic, for the first month after removing it from its packaging. PEVA can also be used as a drug delivery device, when it is mixed with a drug and implanted, in order to slowly release the drug compound into the body in time. Top-of-the-line soccer cleats, boxing gloves, ski boots and bicycle saddles are also common uses of PEVA, too.


Emphasis and Word Order
Емваза со поредиям словес
21.1 The Particle же
The particle же źe has two functions: simple emphasis and contrastive emphasis.
When preceded by an interrogative, as has previously been mentioned, же strengthens the force of the question. It is usually written cliticized to the interrogative. If the interrogative ends in a vowel, it reduces to simply -ж ; if it ends in /j/, it becomes -иж -iź.
1 Какож оне тако буистрѣ суди приходиле?
Kákoź óne táko buístrě sudí prihódile?
how-emph he.nom so fast-adv to_here arrive-past-masc
"How the heck did he get here so quickly?"
After any other part of speech, же serves a contrastive function. In such a role it is always written as a separate word, even though it is phonetically unstressed and tends to cliticize to the preceding word. This form does not reduce to ж.
It most commonly appears after nouns and adjectives. It indicates that only the preceding group specified by the previous word is involved, and not any other. Both are demonstrated below:
2 Яс повастале обух друж туоих, но Рая же мнѣ кағьеци симпатнейшей.
Iás povástale óbuh drúź tuojíh, no Ráia źe mně́ káğjeci simpatnéiśei.
I.nom meet.pf-past-masc both-gen friend-gen.pl your-gen.pl, but Ráia-nom emph I.datins seem-3sg-mid nice-comp-datins.sg.fem
"I've met both of your friends, but Ráia seems nicer to me."
3 Принези плави же тарѣлки со шкавѣ, прусим.
Prinezí plávi źe tarě́lki so śkávě, prúsim.
bring_over.pf-2sg.imper light_blue-nom.pl emph plate-nom.pl from_off cabinet-gen.sg, please
"Grab the blue plates from the cabinet, please. (and not any of the others)"
If же and the topical marker то fall on the same word, they merge into a single invariable form -че če, attached to the word by a dash. In older texts this may also be written -тже -tźe or -тше -tśe. If the word would normally take the inverted topical marker -от, the combined emphatic/topical marker is spelt -оче -óče.
4 Оғо ѣм, но паста-че моей прѣлубимой ѣдой.
Oğó iě́m, no pásta-če moiéi prělubímoi iědói.
all.acc.sg.neut eat-1sg, but pasta-nom.sg-emph.top Ø my-datins.sg.fem intens-beloved-datins.sg.fem food-datins.sg
"I'll eat anything, but pasta I love the most."
21.2 The Particle и
The particle и i is a verbal emphatic (as in example 5 below), which is placed before the verb to be emphasized, though phonetically it cliticizes to the previous word. It can also be used to emphasize adverbs modifying the verb. However, this is a long-distance effect; the emphatic is still placed before the verb, as in example 6.
5 Тако и бадет.
Táko i bádet.
thus emph be.fut-3sg
"It will be so."
If the noun preceding it is a masculine singular fourth-declension noun ending in -е or a nominative fifth declension noun, in either the nominative or inanimate accusative case, the case ending elides.
6 Суде кеняз и жиле.
Sudé keniáz i źíle.
here price-nom.sg emph live-past-masc
"The prince lived here."
21.3 Word Order
Novegradian has free word order, meaning the main elements of a sentence can be rearranged with few restrictions. However, each possible ordering carries its own subtle meanings. To fully explain the subtleties of each may be impossible, but the following should provide a rough idea. The simple sentence Яс лублун тебе "I love you", with only a subject, object, and verb, will serve as an example.
SVO: Neutral word order, with primary emphasis placed on the object: Яс лублун тебе "I love you
SOV: Neutral word order, with primary emphasis placed on the verb: Яс тебе лублун "I love you"
VSO: Strong emphasis on the verb and the subject's connection to that verb: Лублун яс тебе "I do love you"
OSV: Strong emphasis on the uniqueness of the object and its relation to the subject: Тебе яс лублун "You I love (and no one else)"
VOS: Strong emphasis on the quality of the verb and the object's relation to the subject: Лублун тебе яс "I definitely love you"
OVS: Strong emphasis on the identity of the object and its relation to the subject: Тебе лублун яс "You I truly love"
Note, however, that the presence of any additional elements complicates the meanings. When a topical marker is present, there is a tendency for it to go on the most strongly emphasized word, but by no means an absolute one. This is highly context-dependent.

Working together: Save Before Exit and Tabular Forms
Here are some guidelines to properly integrate the two:

Saving Current Values with Cascading LOVs
A friend, Monty Latiolais, recently asked an interesting question regarding cascading LOVs:
Say you've got two LOVs...STATES and CITIES. They both default to 'ALL' and 'ALL'. Since CITIES is dependent on STATES, as soon as STATES is changed, CITIES is blanked out. What should happen is that CITIES gets re-evaluated as in the following example... let's say STATES is ALL and CITIES is "Houston". If one then changes STATES to "Texas", CITIES should remain "Houston" as that is a valid value for CITIES.
So basically, is it possible to maintain the selected value of an item if that same value exists in the list of values after refreshing? That's a great question! Thanks to new events in the APEX framework and Dynamic Actions the solution is far easier than it would have been in the past!
Click here to see the demo but continue reading to learn how it all works…
There are a three main events you need to be concerned with when it comes to cascading selects:
 - change
 - apexbeforerefresh
 - apexafterrefresh
The change event is a standard part of JavaScript and the DOM. This event fires when the user manually changes the value of the select list but can also be triggered programmatically via JavaScript. The apexbeforerefresh and apexafterrefresh events are custom events in the APEX framework. They fire just before and just after AJAX requests refresh something on the page. The events work with many items and regions that utilize this technology.
In this example we have two select lists: parent and child. If you change the value of the child select list then the change event will fire and that's it. But if you change the value of the parent select list a lot more happens to the child select. Here are some of the highlights:
 1. The current LOV values are cleared out
 2. The apexbeforerefresh event is triggered
 3. An AJAX request brings back new values. This only happens if
 1. optimize refresh is set to false
 2. optimize refresh is set to true and all parent items are not null
 4. The apexafterrefresh event is triggered
 5. The change event is fired
Now, knowing all of this, how can we utilize the sequence of events to solve the original problem of keeping selected values? The answer lies in creating two dynamic actions.
The first dynamic action will store the current value of the select list so that we can access it later. This will typically happen when the change event fires but it will also happen when the page first loads. Here's how to create the first Dynamic Action:
 1. Right click the child select list and select Creation Dynamic Action.
 2. Select Advanced.
 3. Click Next >.
 4. Enter a name for the first Dynamic Action.
 5. Click Next >.
 6. Set Event to Change.
 7. Click Next >.
 8. Set Action to Execute JavaScript Code.
 9. Set Code to: $(this.triggeringElement).attr('data-last-value', $(this.triggeringElement).val());
 10. Click Next >.
 11. Click Create.
The second Dynamic Action will take advantage of the apexafterrefresh event and access the previously stored value. That value will then be used to look through the new options and if a match is found it will be selected. Here's how to create the second Dynamic Action.
 1. Right click the item (again) and select Create Dynamic Action.
 2. Select Advanced.
 3. Click Next >.
 4. Enter a name for the second Dynamic Action.
 5. Click Next >.
 6. Set Event to After Refresh.
 7. Click Next >.
 8. Set Action to Execute JavaScript Code.
 9. Set Code to: $(this.triggeringElement).children('option[value="' + $(this.triggeringElement).attr('data-last-value') + '"]').attr('selected','selected');
 10. Click Next >.
 11. Click Create.
So two lines of actual code, not bad at all!

Plug-in Update: SkillBuilders Super LOV 1.2
The APEX community has been providing us with lots of great feedback on Super LOV thus far... Keep it coming and we'll keep making it better!
This release includes the following changes:
 1. Integrated buttons in the main input. The buttons are styled using jQuery UI which is consistent with the rest of the plug-in. Also, the "clear" button switches to a confirmation button to help prevent accidental clearing.
 2. Added "Effects Speed" attribute. Many people have had great things to say about the transition effects implemented in Super LOV but some people complained they were too slow for heavy data entry. Now you can adjust the speed to make it faster or set it to instant which essentially disables the effects altogether.
 3. Added "Default Search Column Number" attribute. Currently this will just default the column that is searched when the modal dialog is opened. This attribute will become even more important with the next release – when the item can be made "enterable".
 4. Fixed bug that prevented Cascading LOV attribute from working. The item now "cascades" as it should with both parent and child items.
Future plans include:
 1. Making the input "enterable". This will allow a user to focus in the main input and begin typing. If a single match is retrieved in the LOV, then the hidden item will be updated and the LOV will never open. If multiple matches are found then the LOV will open "pre-filtered" to allow for selection.
 2. Allowing LOV selection to update multiple items/elements. Lot's of people (especially those from Oracle Forms) have been requesting this functionality so we've added it to the list.
To get this plug-in, as well as our other plug-in offerings, visit new "Plug-ins" page at Future plug-in releases, including this one, must be downloaded from that site. Downloads require free registration, but it's a small price to pay for some great functionality. Smile Enjoy!

This example shows how to use the Graph Cut option in the Image Segmenter app to segment an image. Graph cut is a semiautomatic segmentation technique that you can use to segment an image into foreground and background elements. Graph cut segmentation does not require good initialization. You draw lines on the image, called scribbles, to identify what you want in the foreground and what you want in the background. The Image Segmenter segments the image automatically based on your scribbles and displays the segmented image. You can refine the segmentation by drawing more scribbles on the image until you are satisfied with the result.
The Graph Cut technique applies graph theory to image processing to achieve fast segmentation. The technique creates a graph of the image where each pixel is a node connected by weighted edges. The higher the probability that pixels are related the higher the weight. The algorithm cuts along weak edges, achieving the segmentation of objects in the image. The Image Segmenter uses a particular variety of the Graph Cut algorithm called lazysnapping. For information about another segmentation technique that is related to graph cut, see Segment Image Using Local Graph Cut (Grabcut) in Image Segmenter.
Read an image into the workspace. For this example, read the sample image
baby.png into the workspace.
b = imread('baby.jpg');
From the MATLAB® toolstrip, open the Image Segmenter app. On the Apps tab, in the Image Processing and Computer Vision section, click Image Segmenter.
On the app toolstrip, click Load, and then select Load Image from Workspace. In the Import from Workspace dialog box, select the image you read into the workspace. The Image Segmenter app displays the image you selected.
You can also open the app using the
imageSegmenter command, specifying the image:
On the Image Segmenter app toolstrip, select Graph Cut.
The Image Segmenter opens a new tab for Graph Cut segmentation. As a first step in Graph Cut segmentation, mark the elements of the image that you want to be in the foreground. When the Image Segmenter opens the Graph Cut tab, it preselects the Mark Foreground option. To mark an object as foreground, draw a line (also called a scribble) over the object. When you draw a line, try to include all the different values in the object you want to segment. You can draw as many separate lines as you like. If you are not satisfied with the lines you draw, you can always edit them. Click Erase and move the cursor over any part of the line you want to remove. If want to start over, click Clear Markings.
Next, click Mark Background and draw scribbles to mark the elements of the image you want to be the background. When you finish drawing the lines, the Image Segmenter immediately performs the segmentation (shown in blue).
To refine the segmentation, continue drawing foreground and background lines. For example, there are several areas near the bottom of the image that need to be removed from the foreground. To fix these problems, draw additional background lines on these parts of the image.
To get a better look at the segmentation, click Show Binary.
When you are satisfied with the segmentation, click Create Mask in the toolstrip on the Graph Cut tab. The app closes the Graph Cut tab and returns you to the Segmentation tab.
When you return to the main Segmentation tab, you can use tools to refine the mask image, such as Morphology and Active Contours. To save the mask image, click Export. You can also use the Export option to obtain the code the Image Segmenter app used to create the segmentation.

|Possible Values:||none | left | right | both
|Applies to:||All elements
The clear property specifies if an element allows floating elements to its sides. A value of left moves the element below any floating element on its left; right acts similarly for floating elements on the right. Other values are none, which is the initial value, and both, which moves the element below floating elements on both of its sides. This property is similar in function to HTML 3.2's , but it can be applied to all elements.

A-level Geography/AS OCR Geography/Urbanisation in LEDCs
Since the 1950's the majority of LEDCs have been transformed from Rural to Urban societies. Many have switched from supporting themselves through agriculture to earning a wage from factory work or service job.
This was a typical social/economical upheaval in the 20th century.
Urbanisation in MEDC has slowed whereas in LEDCs it has increased dramatically. However this is not true everywhere. For example in 1980 - Latin America slowed down, yet Asia and Africas urbanisation continued.
Big megacities in LEDCs are São Paulo, Brazil and Mexico City, Mexico.
Causes of Urbanisation in LEDC
- Rapid populational growth, for example, in 1950, Kenya had a population of 5.4 million, by 1995 it had risen to 28.3 million.
- Modernisation of technology, in agriculture, this signifies that fewer workers were needed on the farms, leading many to move to the cities in search of opportunities.
- General pull factors for LEDC Cities. Cities provided a chance for higher standard of living, more and better job opportunities, easier access to services and infrastructures (entertainment, health and transportation for instance).

Fade Out Images with GIMP
There's no need to go out and buy Adobe Photoshop and take Photoshop classes. Just follow this simple GIMP tutorial to learn how to fade out the edge of an image.
One of the features that gives images a web 2.0 kind of look is fading out the edges. This is most commonly seen in the image reflection effects. I'm not going to cover a reflection in this post. I'll just cover the image fade out part for now.
I'm going to start out with an image of our favorite Linux mascot, Tux. I've already trimmed out the white background and made it transparent.
Add a Layer Mask
- Open up the Layers menu [CTRL][L]. If you're opening just a basic jpeg or png there should be just one layer at this point.
- In the Layers menu, right click on the layer and select Add Layer Mask.
- Make sure White (full opacity) is selected and click Add. You should see a white box show up next to the thumbnail of your image in the Layers menu.
Create the Fade Effect
- Right click on your layer and make sure that Edit Layer Mask is selected.
- Make sure that the Foreground Color is set to Black and the Background Color is set to White in the GIMP tools menu.
- Click on the Blend Tool (it should be just to the right of Bucket Fill).
- Drag a vertical line from the bottom of the image to where you want to stop the fade effect. (Hint: Hold down the [CTRL] key to help make the line vertical.)
If you right click in the Layers menu, you can select Show Layer Mask. It should look something like this:
Right click again and select Apply Layer Mask.
You can now save your file. In the image window select File?Save As. Enter a new name and click Save. A menu will pop up with save options. The defaults should be fine. Click Save.
Here's the final product.

Portraying the characters and events of a small Midwestern town at the
end of the nineteenth century, Winesburg, Ohio
is a chronological cycle of
stories which reads like an episodic novel. Centring on George Willard, a
young local reporter with big-city aspirations, and his conversations with fellow
inhabitants, the book gives voice to a disparate cast of figures and lays
bare the constraints and struggles of life in a small community.
A landmark work of American naturalism and a priceless chronicle of rural
life, Winesburg, Ohio
has been compared to the writings of Turgenev,
Chekhov, Dreiser and Twain, and hugely influenced authors such as Steinbeck,
Hemingway and Faulkner.

Published on Friday, 24 August 2012 02:29
Australia's largest vegetation management company is using cutting-edge mapping technology to combat a key cause of the dangerous bushfires and blackouts that plague the nation each year: severed powerlines. Using technology from Geographic Information System (GIS) specialists Esri Australia, Active Tree Services developed a high-tech vegetation monitoring and management system which layers detailed maps of electricity networks over weather and vegetation data.
Powerlines severed by falling branches during extreme weather have been linked to several bushfires in recent years, including the 2009 Victorian Black Saturday tragedy that claimed a total of 173 lives.
Over the past summer, fears that extreme heat and high winds would lead to severed powerlines and more bushfires led to electricity cuts in large parts of South Australia, while thunderstorms and scorching temperatures caused similar concerns in Victoria, Queensland and Western Australia.
Active Tree Services Chief Information Officer Justin Sheppherd said there was a need for a new approach to vegetation management.
"Trees around powerlines can lead to increases in the risk of electricity supply disruptions and bushfires," Mr Sheppherd said.
"Systems are needed to comprehensively identify and complete maintenance work to reduce these risks and meet compliance standards.
"GIS technology enables us to map large amounts of information about the condition and location of vegetation around powerlines, which in turn results in better reporting and clearer transparency about the risk to the network."
Mr Sheppherd said their GIS-driven vegetation management system allowed information to be uploaded directly to a centralised data portal.
"We then integrate this information with other layers of data displaying management histories, tree species and other factors," Mr Sheppherd said.
"The end result is a detailed picture of the state of the nation's electricity network – helping us ensure every branch along the powerlines we monitor is properly maintained."
Active Tree Services' vegetation management system will be on-show this September at Ozri 2012 - Australia's leading GIS technology event.
Ozri 2012 Technical Director Kellie Persson said Active Tree Services' had been selected to present at the conference as they showcase one of the most advanced and robust asset data collection and management systems in the world.
"Through their creative use of GIS technology, Active Tree Services have created an interactive, digital dashboard of their areas of operation – which provides a level of insight and situational awareness that previously wasn't available," Mrs Persson said.
"For example, while a current vegetation management cycle might dictate trees near powerlines in a certain area should be cut back every three years, other uncontrollable external factors may come into play, such as drought or flood.
"GIS technology enables Active Tree Services to analyse these scenarios and delay or bring forward the cycle, which results in a safer environment, reduces over or under-servicing and delivers more efficient resource use.
"It's a best practice asset management model that users from any industry can take inspiration from – and will certainly be a talking point amongst more than 500 leading GIS professionals attending Ozri 2012."
Hosted by Esri Australia, the market leader in Australia's $2.1 billion spatial industry, Ozri 2012 is the largest GIS conference in the Asia Pacific.

Technology Fee Advisory Committee Funding
Technology Fee Focus Group
Technology Fee Committee
Focus Group of Students
Results (February 17, 1999)
Conducted and Prepared by:
NDSU PRSSA: Bobby Prevost and the following members:
Lisa Sedlacek Jill Carlson
Angie Nelson Brigid Ryan
Heidi Guggisberg Tracie Popma
Bipasha Ray Beth Sagsveen
Most Prevalent Themes in Student Focus Group:
Students feel the modem pool/access is a vital technology at NDSU and should remain a high priority for funding.
Printing is another vital technology that students have access too, and this should remain a priority for funding.
All classrooms should all be equipped with efficient and adequate technology to make the students experience as positive as possible.
Discussion on General Technology
What is technology?
The students defined technology as anything that improves our way of life or makes our lives easier. Most felt that technology is a tool that makes what we do faster and more efficient. The most common technologies that were mentioned were: computers, modem access, and modem pools.
The group felt that technology goes far beyond computers and modems however. Cars, and advanced medical drugs were also mentioned as types of technology.
How does technology affect your educational experiences?
The group felt their educational experiences at NDSU have been greatly affected by technology. The technology most beneficial to the group was:
1) E-mail communication between students and professors.
2) Computer clusters available in the residence halls so you don't have to own your own computer.
3) Instructors who have web sites where you can retrieve notes and get class syllabi. The group also felt however, that some professors move too fast in class because they put so much information on the web.
What technology experiences will be necessary for your career?
The group discussed themes they felt were relevant regarding technology and their future careers. The three most prevalent themes were:
1) Access to the Internet. The group felt that the Internet would become more of a necessity as they move into their careers.
2) Knowledge of basic computer functions such as e-mail and word processing was also mentioned.
3) Knowledge of basic navigation functions of the Internet was mentioned as a necessity as well. These experiences they felt applied to everyone because they ease the complexity of many situations and speed the time it takes to do calculations.
What technologies do you see being used by faculty in the classroom?
The technologies that students mentioned most are:
1) Microphones for presentations
4) Use of links/networking on the Internet
5) Instructors' notes on the web/printed notes
6) Projectors with LCD
7) PowerPoint instruction
8) Assignments on the Internet
The students mentioned that sometimes the use of technology doesn't seem worth it because it takes so long for the instructor to figure out how to work it, wasting class time. They felt either they all need to know how to use it effectively or an instruction manual should be available to them. It was agreed that it is the professors' responsibility to know how to work the technology they are using.
What technology experiences should the student bring to the classroom?
The group felt there are specific experiences the students need to bring to the classroom. They are:
1) knowing how to search the web, because some students have never used computers before,
2) Computer system training,
3) Students should have knowledge of Windows 95, which could be taught during orientation,
4) The students prior to classes should know basic computer skills such as typing and math calculations.
It was also mentioned that there should be different levels of computer classes offered and placement test should be available. The group felt that there should be some type of overall requirement to get into some classes and there should be some courses for students with no prior computer experience. It was mentioned that the current levels of computer classes offered are confusing.
What technologies are necessary for supporting student learning?
Students felt that use of the web for posting class syllabi, notes and assignments is very useful and makes the material much more accessible. However, there were several complaints including:
1) Instructors often waste valuable time trying to figure out the equipment (such as PowerPoint),
2) Some professors go too fast because they put so much on the web and go over less in class,
3) Students have to cram because so much information is on the web.
It was also mentioned that having so much information on the web makes it easier to skip classes.
Discussion on Funded Projects
Which of the funded Technology Fee Projects are you aware of?
This question spurred a large discussion, most, of which included questions regarding where the money is spent. Some students however, were aware of several of the projects. Projects that were mentioned include:
Outfitting of 2 classrooms each year with computer hook-ups and LCD's
Residence Hall clusters
Money to pay assistants in clusters
Some students mentioned that the residence hall clusters are extremely beneficial because students can easily access their e-mail accounts. They also felt that having clusters in different buildings was beneficial because it made the computers more accessible.
Some of the complaints included:
1) There needs to be an increased number of assistants in the various clusters. There was also a concern as to how well the assistants were trained. Some felt that they were often unable to answer the students' questions when asked.
2) It was also mentioned that too much money goes into laptop funding. The students believed there are not enough students using laptops to justify the amount of money that is spent on them. They also stated that the price for an Ethernet card is too high. It was voiced that during high-usage times, it is difficult to get a line.
3) Some felt that the University Village and Bison Courts should have computer hook ups.
4) Some people come into use the Stockbridge computer cluster from across the street even though they don't live there.
What projects affected your campus experience?
The group agreed that there were several projects that had a significant impact on their campus experience. These projects include:
1) Residence Hall computer clusters
2) Laser Printing
3) Scanning Machines
What effect did these projects have on your campus experience?
The students agreed that many of the funded projects have made for a positive campus experience. Accessibility to the latest equipment was the most common theme of the discussion. Projects the students felt have impacted their campus experience included:
1) Residence Hall clusters which made it easy to access the computer programs and e-mail accounts.
2) Classrooms equipped with the latest computer technology. Participants felt that more classrooms should be better equipped.
3) All students agreed that Laser printing is vital because it gives them access to quality printouts every time. More printers in the clusters were also suggested.
Which projects should be continued?
The group felt that most all the projects were worthwhile. The ones that most of the students agreed on were:
1) Laser Printing
2) Modem Pool
3) Residence Hall Clusters
4) Multi-media carts
It was suggested that the modem pool be upgraded to 56k. The reason for this would be that it would minimize the downloading time and people wouldn't be on the computers as long.
Which projects should not again be funded?
There was only mention of one project they felt was not as worthy of tech fee dollars. That was the money allotted for the laptop hook ups. The reason cited for this was that there are such a small number of students using them. There was a fair amount of discussion however, regarding the fact that Architecture students are required to have laptops making the laptop hook-ups necessary.
Although not directly related to the question, some students felt that the information on campus regarding where the technology is located is very poor. They felt that many students don't know where things are such as the data ports in Morrill. It was suggested that the information be included in orientation and be posted in the buildings.
Discussion of the Funding Process
Was the funding process fair last year?
The discussion on the funding process was quite brief. The students felt they had limited knowledge regarding the process and therefore could not make an entirely accurate judgement. However, as far as they knew, the process was relatively fair.
Have any of you been involved in a grant or applied for a grant from the tech fee committee?
No members had been involved or applied for a grant from the tech fee committee.
What kind of information would you like to receive after the grant application process?
This question was not applicable to the group.
If you were denied funding from the tech fee committee, were you provided with enough information to understand why you weren't funded?
This question was not applicable to the group.
Discussion of Future Changes
How would you rank the target areas for last years fund cycle?
The group discussed two areas they felt were very important to the funding cycle:
1) Printing is vital to students, although there is far too much waste,
2) Technology should be made more handicap accessible.
It was discussed that printing waste is a huge problem in the clusters. Suggestions to stop this waste were to possibly have scanned cards students used when they printed. It was also mentioned that maybe there could be more people employed to look after this problem.
Would you eliminate any target areas from this year's request for proposals?
This question did not generate much discussion either because the students felt that they were not knowledgeable enough to make a judgement.
What new target areas would you add?
This question did not generate much of a discussion. The students felt that some areas that need improvement (some non-technology) were:
1) New screens to pull down for overhead projectors because many are dirty and ripped (specifically in Minard),
2) New desks are needed in many of the building as the current ones either need to be repaired and in some cases, are too small,
3) Technology for students with disabilities.
How would you change the funding process?
The group did not

text: We present global upper tropospheric HCN and C2H6 amounts derived from MIPAS/ENVISAT limb emission spectra. HCN and C2H6 are retrieved in the spectral regions 715.5–782.7 cm−1 and 811.5–835.7 cm−1, respectively. The datasets consist of 54 days between September 2003 and March 2004. This period covers the peak and decline of the southern hemispheric biomass burning period and some months thereafter. HCN is a nearly unambiguous tracer of biomass burning with an assumed tropospheric lifetime of several months. Indeed, the most significant feature in the MIPAS HCN dataset is an upper tropospheric plume of enhanced values caused by southern hemispheric biomass burning, which in September and October 2003 extended from tropical South America over Africa, Australia to the Southern Pacific. The spatial extent of this plume agrees well with the MOPITT CO distribution of September 2003. Further there is good agreement with the shapes and mixing ratios of the southern hemispheric HCN and C2H6 fields measured by the ACE experiment between September and November 2005. The MIPAS HCN plume extended from the lowermost observation height of 8 km up... mehrto about 16 km altitude, with maximum values of 500–600 pptv in October 2003. It was still clearly visible in December 2003, but had strongly decreased by March 2004, confirming the assumed tropospheric lifetime. The main sources of C2H6 are production and transmission of fossil fuels, followed by biofuel use and biomass burning. The C2H6 distribution also clearly reflected the southern hemispheric biomass burning plume and its seasonal variation, with maximum amounts of 600–700 pptv. Generally there was good spatial overlap between the southern hemispheric distributions of both pollution tracers, except for the region between Peru and the midPacific. Here C2H6 was considerably enhanced, whereas the HCN amounts were low. Backward trajectory calculations suggested that industrial pollution was responsible for the elevated C2H6 concentration in these particular air masses. Except for the Asian monsoon anticyclone in September 2003, there were only comparably small regions of enhanced HCN in the Northern Hemisphere. However, C2H6 showed an equally strong northern hemispheric signal between the equator and low midlatitudes, persisting over the whole observation period. Backward trajectory calculations for air masses from this region also point to industrial sources of this pollution. Generally, C2H6/HCN ratios between 1 and 1.5 indicate biomass burning and ratios larger than 1.5 industrial pollution. However, in March 2004 ratios of up to 2 were also found in some regions of the former southern biomass burning plume.


Gift cards
There are three gift cards in different price classes and with different levels of excitement.
111.- The first and most advantageous is mormyshka fishing or summer angling. The duration of the fishing day is 6 hours. Under the guidance of the fish guide, smaller target species, such as: roach, ruff, bleak, perch, bream are caught on ice in winter or by angling (with a simple hand line) from the shore of the water body in summer. By applying these fishing methods, the primary success experience can be ensured, especially for children, but they have always provided excitement for adults as well. A particularly meditative activity is spring migratory roach fishing, because then it is possible to catch larger quantities of fish for drying. Number of participants up to 2.
222.- The second gift card includes winter tipup fishing on some larger lakes. Trapping is a way to catch some particularly big predator. The fishing takes place where the fish is currently biting. The best area for these occasions is Vooremaa, where there are several small lakes rich in fish. During free water, you can take a motorboat on Kuremaa and Saadjärv, Võrtsjärv and, of course the Suur-Emajõgi, Pede River and their old rivers in the Alam-Pedja nature reserve area. Duration of the fishing day is 8 hours. Number of participants up to 2.
333.- The third gift card is for occasions if you want to make a special impression on the recipient. In these cases, the motorboat undertakes longer sea voyages to catch sea trout, pike or garfish. The fishing areas are the entire west coast with its archipelago, as well as the archipelagos of Northern Estonia. There are pantries in our seas, where dozens of pike can be pulled into the boat in one hour, and it is not uncommon to see water surface boiling of the garfish while they are spawning The boat also gives access to the most adrenaline-laden flocks of sea trout. Such fishing trips are always remembered and it is not uncommon for them to become traditions. The duration of the fishing day is 8-10 hours. Number of participants up to 2.
The fourth gift card is intended, for example, for those occasions when you want to celebrate your friend's birthday with a fishing trip on the water or ice. In this case, we will arrange fishing, water transport, catering and if desired, a sauna and accommodation. There are no limits to the number of people and we are also flexible in terms of price. For example, we have organized a fishing trip to Pedassaare, which includes a boat trip to the island, sea trout fishing by wading from the shore and hiking around the island, a fish valuation workshop, making a campfire and eating the catch together. The nature of Pedassaare is unique and non-fishermen can come along as well. Everyone will find the soul there, because the island is rich in mushrooms and berries, and there is a variety of beach types, birds and plant species.

Cocoon Source Resolving
Differences between Cocoon and Avalon Excalibur Source Resolving
This story tries to list the changes between the two source resolving approaches. Originally, the source resolving was developed in the Cocoon community. As the community recognized that it had a more common value, the source resolving was donated to the Avalon Excalibur project and there it was refined and redesigned. Now the way back takes place by reintegrating the Avalon Excalibur Source Resolving into Cocoon and deprecating the now obsolete Cocoon Source Resolving.
The Interfaces
Besides the package names the main difference is that the Cocoon Source object is XMLizable, that means it can directly send SAX events. The AE Source object is not XMLizable, which is more correct as a protocol only describes the way of transport but not the format of the data which is transfered. Therefore it provides a getMimeType() method.
The Cocoon Source object returns a last modified time stamp which is very limiting. For example a source could have an expires date or something like that. The AE Source returns a validity object which is capable of all these validity checkings. So the information used for validity checking is provided by the source object and not maintained by the client of the source as it is currently in Cocoon.
As we in Cocoonland are dealing a lot with XML, a Source implementation can still implement the XMLizable Interface (from AE and not from Cocoon!) to directly provide SAX events. The Cocoon SourceUtil class has a method toSAX() which gets a Source object and tests if it implements the XMLizable interface. If not the new AE XMLizer is used which is a component that can convert an input stream with a given mime-type to SAX events. This component is configurable and extensible.

I want to know what exactly is different in the verbs "mischen" and "vermischen". Both of them mean to mix.
Is there any example where they can mean a specific thing? Are they interchangeable?
share|improve this question
Depends on context. A generic answer might be that vermischen is rather "to mix up, muddle, and/or confuse" while mischen is more deliberate. However, there certainly quite a many contexts that proves me wrong on that. – Em1 Apr 22 '14 at 12:58

An example where only one of the options is appropriate: Shuffling a deck of cards is always "mischen", never "vermischen". As a rule of thumb use "mischen" on countable sets and "vermischen" when the result is homogenous.
Beware: "mixing a drink" is neither: the correct translation is "einen Drink mixen".
share|improve this answer
well "einen Drink mischen" is not unheard of... – Vogel612 Apr 28 '14 at 16:50
Maybe its helpful that "vermischen" indicates that there are at least 2 components while "mischen" can be of one substance. Also look for the Noun " das Gemisch" there is no noun of "vermischen".
share|improve this answer
I upvoted because the 2-component-point is very pertinent, but I have to contest the last sentence: "Vermischung" and "Vermischtes" exists. – Phira Apr 24 '14 at 23:52
According to the german wiktionary the preposition "ver-" has several meanings (well it's an old complicated language) amongst these is the notion of a "prcess that is hard to reverse" like in to fall in love sich ver-lieben. I guess that might be a good explanation. So it wants to emphasize a process of mixing that is irreversible. So if you mix water you sill end up with water. but if you mix water and sugar (so two or more components) and you "vermisch" them then they are really mixed without an easy way to separate them. this is opposed to the deck of cards that would be easy to demix if you shuffled it.
From my feeling as a native these two words can be interchanged quite frequently without a drastic change. So if someone told me "ich vermische die Karten" I would not feel compelled to correct him ;-)
share|improve this answer
Very good points about the irreversibility, but "ich vermische die Karten" for a professional act of shuffling feels very wrong. – Phira Apr 24 '14 at 23:58
I agree it is not the really right thing, however if someone would say that I would not feel compelled to correct him in the same way as if he said "ich vermenge die Karten" for example. Also if you say "ich vermische die roten mit den grünen Karten" it would feel right again, wouldn't you say? – Magellan88 Apr 25 '14 at 8:56
"Kannst du die Karten noch einmal mischen, damit Herz und Treff besser vermischt werden?" would sound alright. – Phira Apr 25 '14 at 23:42
Yes that's sounds exactly right to me. Just note that treff is usually Kreuz in German (I know people playing bridge usually use the French words) – Magellan88 Apr 26 '14 at 11:31
Karten vermischen? Nope! Da VERwechselst du wohl etwas. – DisplayName Apr 28 '14 at 15:14
mischen - shuffle (bring chaos into some order) vermischen - mix together (mix more than one substance together) Gemisch - Mixture - mixture of more than one component (fertig) gemischt - done mixing something (fertig) vermischt - done mixing two or more components
Yes! Der Mischvorgang ist beendet. No! Der Vermischvorgang ist beendet.
mischen --> generally increasing the entropy somewhere
vermischen --> mixing two or more things of different character together

In this paper, a systematic group contribution based framework is presented for synthesis of process flowsheets from a given set of input and output specifications. Analogous to the group contribution methods developed for molecular design, the framework employs process groups to represent different unit operations in the system. Feasible flowsheet configurations are generated using efficient combinatorial algorithms and the performance of each candidate flowsheet is evaluated using a set of flowsheet properties. A systematic notation system called SFILES is used to store the structural information of each flowsheet to minimize the computational load and information storage. The design variables for the selected flowsheet(s) are identified through a reverse simulation approach and are used as initial estimates for rigorous simulation to verify the feasibility and performance of the design.

Ultrafast monochromator
From Wikipedia, the free encyclopedia
Jump to: navigation, search
An ultrafast monochromator is a monochromator that preserves the duration of an ultrashort pulse (in the femtosecond, or lower, time-scale). Monochromators are devices that select for a particular wavelength, typically using a diffraction grating to disperse the light and a slit to select the desired wavelength; however, a diffraction grating introduces path delays that measurably lengthen the duration of an ultrashort pulse. An ultrafast monochromator uses a second diffraction grating to compensate time delays introduced to the pulse by the first grating and other dispersive optical elements.
Diffraction gratings are constructed such that the angle of the incident ray, θi, is related to the angle of the mth outgoing ray, θm, by the expression
 m \lambda = d ( \sin{\theta_i} - \sin{\theta_m}).
Two rays diffracted by adjacent grooves will differ in path length by a distance. The total difference between the longest and shortest path within a beam is computed by multiplying by the total number of grooves illuminated.
For instance, a beam of width 10 mm illuminating a grating with 1200 grooves/mm uses 12,000 grooves. At a wavelength of 10 nm, the first order diffracted beam, m = 1, will have a path length variation across the beam of 120 μm. This corresponds to a time difference in the arrival of 400 femtoseconds. This is often negligible for picosecond pulses but not for those of femtosecond duration.
A major application is the extraction, without time-broadening, of a single high-order harmonic pulse out of the many generated by an ultrafast laser pulse interacting with a gas target.

Given it's your router you should already know this, but if you wanted to pretend you had no knowledge of the networks logical addressing structure you could use one of the following methods to discover it:
- Do a scan of the appropriate network range using a command line host/port scanner such as nmap, unicornscan, etc. This can be defeated by packet filters (firewalls) on the scanned systems. You also have to know that the appropriate range is, which you can find via DHCP replies or via sniffing.
- Capture traffic on the network and check the source and destination addresses. This requires that each system sends or receives traffic on the network during the time which you are sniffing.
- Access the router and check its DHCP database. Requires that you can access the router. Not all machines with DHCP leases are necessarily currently active on the network.

Iranian Researchers Separate Hydrogen from Methane with 100% Efficiency
TEHRAN (FNA)- Iranian researchers at Kashan University and Research Institute of Petroleum Industry (RIPI) separated hydrogen from methane with an efficiency of 99.99% by hybrid synthesizing of a nanoadsorbant.
Hydrogen has numerous applications in various fields, among which is the use of hydrogen in hydrocracking process.
No source has so far been known in order to obtain pure hydrogen. In order to fulfill the needs of industry, this material is prepared by using water-gas substitution (WGS) reaction through chemical processes. Therefore, the raw materials and the products except hydrogen must be separated from hydrogen in order to obtain pure hydrogen. Since methane is the raw material of the reaction, hydrogen should first be separated from methane, and then it should be transferred to other processes.
The researchers studied the deposition of carbon nanostructures on the active carbon made of walnut shell (which was chemically activated by using KOH). Results of the experiment showed that methane adsorption increased 17.92% for the deposition of nanofiber carbon on the active carbon. However, the increase in methane adsorption did not affect the amount of hydrogen adsorption.
Their experiments also showed that the carbon adsorbent hybridized by carbon nanofibers can separate a mixture of methane and hydrogen with equal concentrations of the compounds up to 99.99, and the outlet gas contained 99.99% pure hydrogen. Commercial adsorbents can purify hydrogen up to 73.80% at standard conditions.
The results of the research have been published in the February 15 edition of the Chemical Engineering Journal.

Here are today's five thing to know about Homemade Soup:
Also: African Heritage & Health Week
- Women are more than twice as likely to eat soup as men, 9.67% vs. 4.0%.
- The Middle English word soupen meant "to drink in sips", which is how most soups were consumed. The words "soup," "supper," "sip," and "sop" are derived from this term.
- Andy Warhol(who's real name was Andrew Warhola) is famous for his Campbell 's soup can art of the 1960's. Did you know his first works sold for around 100 dollars? Today they sell for hundreds of thousands of dollars.
- We 'eat' and don't drink soup. In most cultures, soup is had as a part of the meal. According to etiquette experts, since we consume soup with a spoon as opposed to sipping it from a bowl, we 'eat' it.
- The word soup is of Sanskrit origin! It is derived from the…
