Basic Information About Liquid Nitrogen and Liquid Nitrogen Dewar

Many people do not know much about nitrogen and liquid nitrogen, but most people must heard the breaking news of a young British girl loses her stomach after drinking liquid nitrogen cocktails. Liquid nitrogen used to be only limited in labs and industry fields, but today it got more and popular with some food and recipe applications. Young people love to try fresh things and liquid nitrogen cocktails are welcomed in wine bars. However, directly drinking or touch liquid nitrogen can be harmful to your healthy as since it is dangerously cold. Some people even insists that there should be a law to ban liquid nitrogen cocktails. This suggestion may be not advisable, but we must know something about it before we deal with it, in case of any body damages.

Nitrogen makes up about 78.03% of the air we breath on earth and is often used as an inert gas because of its nonreactive nature with many materials. While liquid nitrogen or LN is pure N2 that has been cooled to the point that it changes from a gas to a liquid. LN is extremely cold – the element turns into a gas at temperatures above -321 degrees Fahrenheit – and has a variety of medical and culinary uses due to its ability to flash-freeze almost anything. One thing we must bear in mind is that LN does not have any health risks or dangers if it is properly handled. We need to know how to handle LN and how to storage it if we are going to do things related to liquid nitrogen.

Due to the special low temperature property, LN is usually stored in a specially made container called cryogenic container or liquid nitrogen Dewar Unlike other gas storage cylinders, LN Dewar seldom have any pressure, since liquid nitrogen is always freezing cold. Such cryogenic Dewars usually are of 3-50 Liters, very convenient to carry from place to place, and there also exist some great volume LN Dewars for lab and industry use. The price for LN Dewar ranges from $300 to thousands of dollars with different volumes. So how to select a reasonable cryogenic container? Here is a general rule that the bigger and better insulated your lcryogenic container, the longer you can store them. Large Dewars for more than 50L capacity of LN Dewar are more efficient in LN storage, but the defect is that they are often too expensive,and they are mostly used in labs and industries. Smaller Dewars are much more convenient to transport and much cheaper, but larger Dewars are more efficient in storage and economical in long-term use.

Conducting Research Through Cognitive Laboratories

Johnson and Duran encouraged use of cognitive laboratories as a means for determining whether lack of access skills impede measurement of target skills. With cognitive laboratories, students work one-on-one with an administrator and answer test questions by thinking out loud. The administrator observes and records the thought process students use in arriving at their answers.

Cognitive labs would allow researchers to compare how students with various disabilities react to the questions under different accommodations and to do further study into what constituted appropriate accommodations. Further Research on the Performance of English-Language Learners Duran commented that better understanding of the achievement of English-language learners depends on improvements in access to appropriate assessment accommodations for these students. He called for additional work to develop ways to evaluate the English proficiency of nonnative English speakers. This is a particularly urgent issue in light of the recently passed legislation. He also encouraged researchers to examine the relationships between performance of achievement tests and relevant background variables, such as length of residence in the U.S., years of exposure to instruction in English, English-language proficiency levels, the characteristics of school curriculum, availability of first and second language resources, and other factors that interact to create different patterns of performance on assessments.

Malouf raised questions about what rate of participation should be expected with NAEP The presentations and his own examination ofNAEP publications indicate that inclusion rates rarely climb much above 70 percent of the students with disabilities and are usually lower. He wondered what the basis might be for judging whether this rate of inclusion was high enough, asking “Should our expectations be based on technical limits, or should they be based on other considerations?” iMaloufcalled for reconsideration of what it means to “rake part meaningfully” in the nation’seducational system, and he urged NAEP’s sponsors to determine ways that all students can participate.

The discussants revisited the issue of providing disaggregated results. Goertz reminded participants that states are required to report these comparisons on their state tests. NAEP’s sponsors have yet to specify their plans for using data from the national or state NAEP programs to report on the performance of students with disabilities compared to that of nondisabled students and the performance of English-language learners compared to that of native speakers. Johnson maintained that it is inevitable that there will be strong pressure on NAEP to report disaggregated results for students with disabilities and for English-language learners. For this part, learning a foreign language needs a leaning tools, many children choose Rosetta Stone Polish and Rosetta Stone Portuguese to learn Polish and Portuguese. Although at this time sample sizes are not large enough to allow reliable reporting at the disaggregated level, NAEP’s future plans for combining state and national samples may produce large enough samples to allow for disaggregation of various groups of students with disabilities. Johnson foresees that when this happens, NAEP will not be able to withstand the pressure to report disaggregated results.

Additional Research Is Needed Malouf also recommended the effects of accommodations that additional research be conducted on on NAEP scores. (item response theory) and DIF (differential item He finds that the IRT i functioning) analyses discussed by Mazzeo are broad in Focus and treat accommodations as single factor, sometimes even combining students with disabilities and English-language learners into a single population. Malouf suggested that NAEP researchers find ways to increase sample sizes to allow study of the effects of specific accommodations and to conduct more fine-grained analyses of accommodations and NAEP.

Complete Security Only Through a Good Identification System

Security has become a prime issue in almost all places where access has to be controlled. Even in places like schools and colleges only legitimate children have to be allowed entry or say in the Metro, only passengers that have paid the fare and have a valid token or Mifare card can travel. Most schools and even business organizations have an identification system in place so that only legitimate persons are allowed entry.

Salient points of an identification system

An Identification systemhas to consider all the administrative and logistics issues that are relevant to the organization and the site that has to be secured. Due consideration has to be given to the number of people to be issued an ID card and the necessary information about each person has to be stored in a database. If photo identity is required then facility to take the photograph and storing a copy is required. An ID printing process has to be established with the card printer having the required features. This printer has to be put to use at the point of issue of the ID cards.

Some places like the hospital buildings or airport terminals require different levels of security for different areas. For example visitors can enter only specific areas during specific timings in an hospital. Only doctors and nursing staff can enter operation theaters or intensive care units. For the ease of scrutiny the identification system in a hospital can issue color coded ID badges to patients, visitors and hospital staff.

Data regarding how many ID cards are issued and of what type, to whom and when each ID card was issued, for visitors or temporary cards, how many were issued and how many returned, lost cards etc has to be carefully maintained to find breach in security if any or to take measures to improve security of the place.

Main components of an identification system

The main parts of an identification system are the following:

1. The database that stores all the information regarding the card holders, cards issued, types of cards, lost cards, cards in stock etc.

2. The ID cards printer that can access information from the database and print the card with requisite security measures.

3. Accessories like the digital camera to take photographs of card holders and are accessed by the printer when the ID cards are printed.

4. Color coded lanyards or badge holders and the issuance of these.

5. Trained personnel for verification of ID cards at the points of entry, exit and sometimes in between as required.

6. Regular examination of reports and physical verification of stocks of cards in hand. 7. Improvements and changes in the identification system after regular study. Thus it is the complete identification system that is responsible for the security of places and organizations and due importance should be given to see that it is fool-proof.

Pieces Of New Dinosaur Match Together By A Puzzler Genius

At we are always fairly proud to promote the merit of jigsaw puzzle building. In fact the enthusiast puzzler appear to develop a lot of abilities and right now we wish to discuss about a jigsaw puzzle enthusiast, Ian Morrison, who managed to have a dinosaur called after him. How did that come about you may wonder? Well, the Royal Ontario Museum, Canada, had been keeping in its drawers for about half a century 3 pieces of dinosaur jawbone fossils without being in a position to put them with each other in a way that would make sense. The pieces were found in Alberta in 1950. Despite David Evans, palaeontologist and head of the ROM’s dinosaur research division, along with a colleague having spent on and off a lot of time over the last six to 8 years they nevertheless couldn’t determine how the fragments could fit.

At that point David Evans and his team decided to call for assistance Ian Morrison who had been a technician for the ROM for about twenty two years and was known for his abilities at solving jigsaw puzzles. Getting a whole new stand at the challenge it took just 10 minutes for Ian Morrison to get these three fragments with each other in a way that made sense and to the great surprise and satisfaction of everyone. It turned out that that beaked dinosaur was an not known species from the leptoceratopsid kind. The herbivore dinosaur is about the size of a big dog and is horned. Evans and his staff named the dinosaur Gryphoceratops morrisoni: in relation to Gryphon the mythical part lion part eagle mythic animal and morrisoni the Latinized name of the blissfully skilled technician.

The Gryphoceratops morrisoni is the oldest one and also the smallest of all the known leptoceratopsids and is thought to be 84 million years old according to the dating of a stone he was discovered under. That is yet another instance proving how in many various fields jigsaw puzzle solving skills can assist. Jigsaw puzzles were in reality conceived in the end of the 18th century, in 1797 for being more accurate, by the Englishman John Spilsbury who took a map of the world on a piece of wood and cut out each and every country to make a tutorial tool to aid kids to study geography. So Jigsaw puzzles leave high to their virtuous tradition and from the instance mentioned before it seems that puzzle solving allowed research to move ahead and we are rather glad about it.
