HISTORY OF TABLE TENNIS The origin of table tennis has never been exactly pinpointed‚ even though it’s a relatively young sport‚ younger than lawn tennis and not much older than basketball. The earliest known form of the sport‚ called indoor tennis‚ was played in the early 1880s by British army officers in India and South Africa‚ using lids from cigar boxes as paddles and rounded corks from wine bottles as balls‚ with a row of books set up across the middle of a table to form the net.

____________________________ Date ____________ THE EFFECT OF CONCENTRATION ON THE RATE OF DIFFUSION PURPOSE: This experiment will explore the concentration gradient by measuring the rate of diffusion in a number of theoretical cells. The objectives for this lab are: (1) To define concentration gradient‚ (2) To explain experimental data concerning different concentration gradients‚ (3) To complete a data table and prepare a graph to illustrate the data‚ and (4) To apply information from this experiment

List of the entire famous scientist Alessandro Volta(1745-1827) An Italian Physicist who was a pioneer in the development of electricity. He created the first electric battery in 1800. This battery gave the world its first continuous‚ reliable source of electric current‚ and led to all important discoveries of the use of electricity. The unit of measuring electromotive force (emf)‚ Volt(v) is named after him. He also proposed the law that the air expands at a constant rate with increasing temperature

SOLUTION AND CONCENTRATION A solution is a homogeneous mixture‚ made up of a solute dissolved in a solvent. Ex. In a water (aqueous) solution of sodium chloride‚ the sodium chloride is the solute and the water is the solvent. Solute – the component that is dissolved or is the least abundant component in the solution. Ex. Sugar‚ salt Solvent – the dissolving agent or the most abundant component in the solution. Ex. Water Common Types of Solution State of Solution State of Solute

Napier in the early 17th century as a means to simplify calculations. They were rapidly adopted by navigators‚ scientists‚ engineers‚ and others to perform computations more easily‚ using slide rules and logarithm tables. Tedious multi-digit multiplication steps can be replaced by table look-ups and simpler addition because of the fact — important in its own right — that the logarithm of a product is the sum of the logarithms of the factors: The present-day notion of logarithms comes from Leonhard

Closeness: A New Privacy Measure for Data Publishing Abstract The k-anonymity privacy requirement for publishing micro data requires that each equivalence class (i.e.‚ a set of records that are indistinguishable from each other with respect to certain “identifying” attributes) contains at least k records. Recently‚ several authors have recognized that k-anonymity cannot prevent attribute disclosure. The notion of ‘-diversity has been proposed to address this; ‘-diversity requires that

6. Below are listed some objects of varying degrees of abstraction. Suggest properties of each of these objects that can be measured by each of the four basic types of scales. There are relatively few pure interval scales found in business research. Almost all text discussions of this scale refer to the example of temperature scales. However‚ some attitude scales such as the Likert and Semantic Differential‚ are claimed to approach interval characteristics. In addition‚ approximate interval scales
