4.2.1 ATM physical layer The ATM physical layer is divided into two sub-layers: the transmission convergence sub-layer and the physical medium sub-layer. Functions of the transmission convergence sub-layer include generating and receiving cells, and generating and verifying the cyclic redundancy check in the header error control field. For correct interpretation of ATM cells it is important to identify the beginning of a cell. In theory, if ATM cells are transmitted as a continuous stream of bits,
Assessment and Diagnosis of Speech and Hearing (2010)
Evaluation and diagnosis of speech and hearing is a very important topic in the therapist speech area, due to the increasing prevalence of voice disorders and hearing impairments. Thus, the curriculum for this degree includes various courses (Clinical Examination of voice and hearing, speech therapy intervention in voice disorders and hearing) that form a framework of study that enables students to develop their training professional work in this broad field (evaluation, prevention and/or rehabi
Energy Power Foods
Feeling low on energy? Maybe it's because you haven't eaten in awhile! Did you know that your food is an example of stored energy? It's chemical potential energy to be exact! And some foods have more energy power than others. This brief news clip gives you tips on how to fight fatigue and the midday blahs by providing several examples of energy power foods. (03:12)
Classroom Percussion
List of suitable pieces for classroom use together with a description of the features of each piece, details of the composer, style and level of difficulty, and the name of the publisher and cost.
The Macrogalleria -- A Cyber Wonderland of Polymer Fun
This site is devoted to analysis of polymers and focuses on SEC, although links to other techniques are provided. It does not go into great detail, but provides a nice overview of critical ideas behind SEC. The link to molecular weight distributions may alos help some students with the concepts behind polymers and polymer analysis. It is written simplistically and in an informal manner, which may put some people off, but others might enjoy it for this reason.
Fibonacci Sequence Activity
NASA Connect segment involving students in an activity that explores the Fibonacci Sequence. The segment explores ratios, measurements, and proportionalities.
Animated Storybook: Rob Goes Missing
In this animated storybook, one of the characters becomes lost during a game of hide and seek. The animals work together remaining calm and using problem-solving skills to find him. The words of the story appear on each page and are highlighted as they are read. ( 8:23)
Animated Storybook: Ben's Musical Adventure
In this animated storybook, Ben, the mouse, decides he would like to learn to play a musical instrument. He becomes discouraged when he cannot immediately play the violin well. He wants to stop, but he is convinced to keep trying. This video teaches patience and perseverance. The words of the story appear on each page and are highlighted as they are read. ( 8:23)

LC Calc (TM) Online. A handy calculator for HPLC computations.
This site contains several on-line calculators for use in liquid chromatography. These include pressure unit conversion, buffer pH, and scale-up factors. Some links may be broken.
Simple Machines and Modern Day Engineering Analogies
Students apply the mechanical advantages and problem-solving capabilities of six types of simple machines (wedge, wheel and axle, lever, inclined plane, screw, pulley) as they discuss modern structures in the spirit of the engineers and builders of the great pyramids. While learning the steps of the engineering design process, students practice teamwork, creativity and problem solving.
Mix It Up
This lesson plan introduces the properties of mixtures and solutions. A class demonstration gives the students the opportunity to compare and contrast the physical characteristics of a few simple mixtures and solutions. Students discuss the separation of mixtures and solutions back into their original components as well as different engineering applications of mixtures and solutions.
7.5.1 Evaluate information from different sources Be critically aware of the reliability and quality of information from different sources, taking into account factors such as commercial, political, academic or personal interests that may influence selection, content and presentation. How will you judge the quality of the information you find? You may need to question the validity of statistical information and the way data have been chosen. The size of a survey sample, for example, may be insufficient to support claims of general tren
