This feature allows users to train their vocabulary in one of 13 different topics including general terms, economy, politics, law, medicine, zoology, and a number of other professional and academic topics. Users can select to go from English to Arabic or Arabic to English. The trainer focuses on Modern Standard Arabic exclusively.
Babylon's Arabic Dictionaries page contains 22 specialized, user-generated, English-Arabic dictionaries and glossaries. Glossary topics include such wide ranging subjects as automotive, financial, dental, medical, and legal terms, as well as biblical and bird names.
In this course, you will learn about prefixes, suffixes, root words, breaking down words into their word parts, and how you can interpret the word, common word parts and common words in medical terminology.
Type of Unit: Concept
Students should be able to:
Write and evaluate simple expressions that record calculations with numbers.
Use parentheses, brackets, or braces in numerical expressions and evaluate expressions with these symbols.
Interpret numerical expressions without evaluating them.
Students learn to write and evaluate numerical expressions involving the four basic arithmetic operations and whole-number exponents. In specific contexts, they create and interpret numerical expressions and evaluate them. Then students move on to algebraic expressions, in which letters stand for numbers. In specific contexts, students simplify algebraic expressions and evaluate them for given values of the variables. Students learn about and use the vocabulary of algebraic expressions. Then they identify equivalent expressions and apply properties of operations, such as the distributive property, to generate equivalent expressions. Finally, students use geometric models to explore greatest common factors and least common multiples.
Students play an Expressions Game in which they describe expressions to their partners using the vocabulary of expressions: term, coefficient, exponent, constant, and variable. Their partners try to write the correct expressions based on the descriptions.Key ConceptsMathematical expressions have parts, and these parts have names. These names allow us to communicate with others in a precise way.A variable is a symbol (usually a letter) in an expression that can be replaced by a number.A term is a number, a variable, or a product of numbers and variables. Terms are separated by the operator symbols + (plus) and – (minus).A coefficient is a symbol (usually a number) that multiplies the variable in an algebraic expression.An exponent tells how many copies of a number or variable are multiplied together.A constant is a number. In an expression, it can be a constant term or a constant coefficient. In the expression 2x + 3, 2 is a constant coefficient and 3 is a constant term.Goals and Learning ObjectivesIdentify parts of an expression using appropriate mathematical vocabulary.Write expressions that fit specific descriptions (for example, the expression is the sum of two terms each with a different variable).
Principles of Industrial Hygiene provides an introduction to the field of industrial hygiene and to occupational health in general. The instructor focuses on introducing concepts, terminology, and methodology in the practice of industrial hygiene and identifies resource materials. The class would benefit those wishing to pursue a Master's degree in industrial hygiene, those wishing to complete a certificate in occupational health, or for students in allied health fields needing a basic understanding of industrial hygiene.
This module defines several key terms related to Probability. The original module by Susan Dean and Dr. Barbara Illowsky in the textbook collection Collaborative Statistics has been modified by Roberta Bloom.
This lesson will be a real-world scenario-based reading module for Reading Scientific and Technical Text, for readers at level 7. Through an interactive visual scenario, learners will be introduced to a sample loan application form, and will be walked through the meaning and purpose of primary portions of the form and challenging terminology in it.
This dictionary of medical terminology was assembled by the World Health Organization in order to "to meet the urgent need in Arab countries for unified medical terms." The current edition of the dictionary contains over 150,000 terms in English and Arabic. Users can search the dictionary on this site.
This is the second in a series of training modules on marine wind and waves. The first module discussed wave types and characteristics and is a good primer to this next marine training topic. Wave Life Cycle I: Generation examines how wind creates waves and the inter-relationships between wind speed, wind duration, and fetch length during this process. These three factors are important to predicting wave height and what will limit wave growth. Additional topics include fully developed seas, observation sources, and various special wind events such as coastal jets and instability mixing in the marine boundary layer. While much of this instruction is at a basic level, all marine forecasters will find benefit in the more intermediate and advanced topics. These include the issue of dynamic or “trapped” fetch as well as the use of satellite-based observations of marine winds using the active microwave technique known as scatterometry. User interactions are included throughout the module and within the short case study. The next module in the series will look at propagation and dispersion as the waves leave the generation area.
This is the first in a series of new marine meteorology modules based on COMET’s old laser disk and CD-ROM modules on marine meteorology. This module is an introduction to waves and their associated characteristics. Several types of waves are presented, from the common wind wave to the rare tsunami wave. The basic physical, mathematical, and statistical traits of waves are discussed, along with how they change once waves become swell. This material serves as a building block to subsequent modules on wave generation, propagation, and dispersion.
To those unfamiliar with financial and economic lingo, the terms bandied about in the news can sometimes make no sense. The January 2012 issue offers some help with explanations of common terms. The essay is accompanied by a table of terms, definitions, and the significance of each to the broader economy.
