The Inaba text describes the phenomenon of "therapeutic index." Addiction to barbiturates can be critical in terms of lethality as measured by the therapeutic index. Describe how this phenomenon might lead to an accidental overdose. Why is this factor more critical with barbiturates than with other classes of depressant drugs? Barbiturates are nonselective central nervous system (CNS) depressants‚ capable of producing all degrees of depression from mild sedation and hypnosis to general anesthesia

FORUM B (5 November 2014‚ 7 – 9.00pm) 1. Can a manager or supervisor “empower” an employee? Discuss fully. - Empowerment is a state of mind‚ so it really mean is that they are changing the work environment to support the feeling of empowerment. - The environment for employee to feel that they have freedom‚ independence and discretion over their work activities - Able to give work meaning to employee so that they care about their work and believe that what they do is important. - Bring out the

Calculate simple indices 2. Determine simple aggregate price indices 3. Use laspeyre’s and Paashe’s price indices to determine weighted indices. What is an index number? An index number is a statistical measure designed to show/ monitor changes over a period of time in the price‚ quantity

wavelength of light. Because the velocity of light in air is always greater than that through a liquid‚ the refractive index is a number greater than 1; for example‚ hexane n20D 1.3751. The superscript 20 indicates that the measurement was made at 20 oC‚ and the subscript D refers to the yellow D-line of a sodium vapor lamp‚ light with a wavelength of 589 nm. The measurement is made with a refractometer using a few drops of liquid. Compensation is made within the instrument for the fact that white

OVERVIEW INDEX NUMBERS compare figures which show changes in a given variable. The most common variables used in index numbers are price and quantity. By getting the difference of the index numbers‚ we are able to determine the relative or percent change in the price or quantity of a commodity between two periods of time or two localities. Among the more commonly used index numbers are the consumer price index‚ retail price index‚ wholesale price index‚ and the cost-of-living index. DEFINITION

CPI (Consumer price index) A consumer price index (CPI) measures changes in the price level of consumer goods and services purchased by households. The CPI is a statistical estimate constructed using the prices of a sample of representative items whose prices are collected periodically. GDP deflator In economics‚ the GDP deflator (implicit price deflator for GDP) is a measure of the level of prices of all new‚ domestically produced‚ final goods and services in an economy. GDP stands for gross

Objective The objective of this experiment is to understand reflection and refraction and how they vary with different matters. At the end of this experiment‚ you will be able to: Determine index of refraction of various solutions Recognize the passage of refracted beams though different medium Understand the concept of Snell’s Law Understand how the speed of electromagnetic waves in different matters are related Determine the critical angle for total internal reflection Materials 550

The refractive index Aim: The aim of this experiment is to find the refractive index of a glass prism. In this experiment‚ the independent variable is the angle of incidence‚ and the dependent variable is the angle of refraction. Theory: Snell’s law relates the angle of incidence and refraction to the ratio of the velocity of the wave in the different media. The formula for Snell’s law is the following: Sin isinr = v1v2 = n Where i is the angle of incidence‚ r is the angle of refraction
