Mechanical Concentration of Gases

Description: From Introduction: "This bulletin deals with a new mechanical means of attacking the problem of separation. Although it is improbable that any one type of separation could hope to find universal application, the method described is to be regarded as an alternative to conventional means that has attractive possibilities in certain instances."

The Period Effect in Reactor Dynamics

Description: From Abstract: "An alternative approach is presented with attempts to demonstrate that insight may be gained from a consideration that the basic cause of the effect may be due to reactivity rather than to period as the previous authors assumed. Methods for compensating for this effect are discussed."

Airfoil-Contour Modifications Based on (Epsilon)-Curve Method of Calculating Pressure Distribution

Description: From Introduction: "Certain alternations of a qualitative nature may be performed in spite of the fact that a pressure change cannot be prescribed. It is the purpose of this paper to indicate a method by which qualitative alternation may be performed. It will be noted that the present method of contour modification will serve the intended purpose of the inverse method."

Analysis of spanwise temperature distribution in three types of air-cooled turbine blade

Description: From Summary: An approximate method for determining the allowable stress-limited blade-temperature distribution is included, with brief accounts of a method for determining the maximum allowable effective gas temperatures and the cooling-air requirements. Numerical examples that illustrate the use of the various temperature-distribution equations and of the nondimensional charts are also included.

A Study of Four-Mallet Grips Used in Playing Keyboard Percussion Instruments

Description: The purpose of this study was to evaluate the efficiency of three common grips used in four-mallet playing. The three grips were referred to as (a) the Musser grip, (b) the cross stick grip No. 1, and (c) the cross stick grip No. 2. A thorough description (including illustrations) was given for each grip. The evaluation of efficiency was made through research testing, which was conducted by the author. Forty individuals participated in the research testing. Four tests were conducted, and each test had ten participants. The individuals who participated in Tests I, II and III had no previous four-mallet experience. The individuals who participated in Test IV had previous four-mallet experience. The evaluation of the efficiency covered by the four tests was limited to (a) horizontal movement of the outside mallet(s), (b) horizontal movement of the inside mallet(s), and (c) horizontal movement of the hand (s). According to Tests I, II and III, the majority of beginning four-mallet players will find the cross stick grip No. 2 the easiest and most efficient (as far as the three movements which were tested are concerned) of the three grips. However, some individuals (a much smaller percentage) will prefer either the Musser grip or the cross stick grip No. 1. Many beginners will find the Musser grip extremely difficult. A very small percentage of beginning four-mallet students will have poor efficiency using cross stick grip No. 2. According to the results of Test IV, the efficiency of the Musser grip and the cross stick grip No. 2 improve at a faster rate than does the efficiency of the cross stick grip No. 1. The movements tested in this study are extremely important when playing with four mallets. However, this study was limited to the testing of three types of horizontal movements and, ...

Characteristics of Groups Taught Under Two Social Climates

Description: The problem of this study is to determine the effects of two different social climates, as created by different teaching methods, upon the characteristics of college class groups. The social climates utilized in the present investigation were: (a) a democratic social climate, and (b) an autocratic social climate. The actual meaning of the adjectives used to label these social climates is necessarily somewhat different from the meanings attributed to them in political or economic discussions.

Automatic Indexing: A State-of-the-Art Report

Description: Report presenting a state-of-the-art survey of automatic indexing systems and experiments. It was conducted by the Research Information Center and Advisory Service on Information Processing, Information Technology Division, Institute for Applied Technology, National Bureau of Standards. Consideration is first given to indexes compiled by or with the aid of machines, including citation indexes. Advantages, disadvantages, and possibilities for modification and improvement are discussed. Experiments in automatic assignment indexing are summarized. Related research efforts in such areas as automatic classification and categorization, computer use of thesauri, statistical association techniques, and linguistic data processing are described. A major question is that of evaluation, particularly in view of evidence of human inter-indexer inconsistency. It is concluded that indexes based on words extracted from text are practical for many purposes today.
