Normative Assessment Technique for Bench Press and Leg Extension Strength in College Females on the Universal Gym

Description: This study was to develop normative data of isotonic muscular strength in college females using the Spartacus model Universal Gym bench press and leg extension and to control for the influence of body weight. Two hundred and two college age females enrolled in weight training and conditioning classes used the Universal Gym for twelve weeks. Subjects were tested for maximum strength on 2 exercises and their percent body fat was calculated. Pearson-product moment correlations between lean body weight , body weight and the bench press test and the leg extension test were correlated. After statistically controlling for the effects of body weight, percentile ranks were calculated for both tests.

Theoretical analysis of incompressible flow through a radial-inlet centrifugal impeller at various weight flows

Description: A method for the solution of the incompressible nonviscous flow through a centrifugal impeller, including the inlet region, is presented. Several numerical solutions are obtained for four weight flows through an impeller at one operating speed. These solutions are refined in the leading-edge region. The results are presented in a series of figures showing streamlines and relative velocity contours. A comparison is made with the results obtained by using a rapid approximate method of analysis.

The Effects of Weight Loading and Repetitions, Frequency of Exercise, and Knowledge of Theoretical Principles of Weight Training on Changes in Muscular Strength

Description: The purpose of this study was to determine the effects of weight loadings and repetitions, frequency of exercise, and knowledge of theoretical principles of weight training on changes in muscular strength. Another purpose was to analyze these effects and determine implications for coaches, physical educators, physical therapists, and others interested in determining the optimum combination of the three variables for increasing muscular strength.

Corner rounding in EUV photoresist: tuning through molecular weight, PAG size, and development time

Description: In this paper, the corner rounding bias of a commercially available extreme ultraviolet photoresist is monitored as molecular weight, photoacid generator (PAG) size, and development time are varied. These experiments show that PAG size influences corner biasing while molecular weight and development time do not. Large PAGs are shown to exhibit less corner biasing, and in some cases, lower corner rounding, than small PAGs. In addition, heavier resist polymers are shown to exhibit less corner rounding than lighter ones.

A Psychosocial Comparison Between Weight Loss Maintainers and Weight Loss Non-Maintainers

Description: Psychosocial differences between weight loss maintainers and weight loss non-maintainers were compared at least one year after reaching a medically approved weight goal through a medically supervised weight loss program. Research questions addressed differences between groups on the dimensions of somatization, obsessive/compulsive issues, interpersonal sensitivity, depression, anxiety, hostility, ability to resolve past emotional issues, social interpersonal relationships, and tolerance of ambiguity. The all-female sample consisted of maintainers of weight loss (N=30), non-maintainers (N=33), psychotherapy maintainers (N=14), and psychotherapy non-maintainers (N=ll). Research instruments administered were the Symptom Checklist-90-Revised, Fundamental Interpersonal Relations Orientation-Behavior, Personal Orientation Inventory, and Budner Scale for Tolerance/Intolerance of Ambiguity. To determine differences between groups, a t test was performed on data relating to the maintaining and non-maintaining groups. An analysis of variance was performed on data related to the maintaining, non-maintaining, psychotherapy maintaining, and psychotherapy non-maintaining groups. An intercorrelation matrix was completed for all variables. Non-maintainers of weight loss had significantly more difficulty with somatic problems as indicated in the results of both the t test and the analysis of variance (p < .009, p < .02, respectively). Non-maintainers expressed more complaints which focused on cardio-vascular, gastrointestinal, respiratory, and somatic equivalents of anxiety (headaches, pain, discomfort of the gross musculature). An analysis of variance showed non-maintainers (p < .05) to be significantly less effective in resolving past emotional issues than maintainers, psychotherapy maintainers, and psychotherapy non-maintainers. Non-maintainers were more burdened by guilt, regrets, and resentments from the past. Results of the analysis of variance indicated that psychotherapy maintainers (p < .03) were more socially adjusted than maintainers, non-maintainers, and psychotherapy non-maintainers. Inclusion and control subscales characterized psychotherapy maintainers to be more socially adaptable and flexible. They assumed responsibility without support of others and were less burdened with fears of helplessness and incompetence.

A Self-Control Approach to Weight Control

Description: A strategy for facilitating post-treatment weight maintenance was examined. Subjects were matched for age, sex, and amount of weight that they desired to lose and were then assigned to one of two groups. Both groups were under contracts and had individually designed self-control programs for weight loss, but subjects in the experimental group lost weight in small steps and subjects in the control group lost weight continuously. The experimental group was predicted to have better weight maintenance after treatment because of a greater number of reinforcements for weight loss. Two-month follow-up data was obtained on the ten subjects who completed the study, and the experimental group was found to have regained significantly less than the control group after treatment ended. The implications of these results for obesity research are discussed.

The Effect of Rapid Weight Loss on the Efficiency of Wrestlers Under Simulated Competitive Conditions

Description: The purpose of this study was to determine the effects of rapid weight loss on wrestlers' efficiency incorporating competitive aspects of the sport into the research procedures. Six subjects were selected from the North Texas State University Wrestling Club. Eight cardiovascular and neuromuscular measurements were taken and recorded before treatment and following treatment. Astrand's bicycle ergometer test was utilized to obtain exhaustive, heart rates. Data were analyzed by a one-tailed t test at the .05 level. Conclusion of the investigation was that following 6.25 per cent rapid loss of body weight, over a period of one week, no loss of efficiency occurred among wrestlers under simulated competitive conditions.

Treatment of Overweight by Avoidance Conditioning

Description: This study investigated the effectiveness of aversion therapy to help subjects achieve and maintain a weight loss. The aversion therapy made use of an avoidance conditioning procedure. Slides of fattening foods were paired with the possibility of receiving an electric shock in an attempt to induce anxiety. Slides of non-fattening foods were paired with shock avoidance and consequent anxiety relief.

Drop Tests of 325 Pound 6M Specification Packages

Description: Testing of 6M specification packages, performed in response to concerns over the integrity of the clamp-ring closure, showed that the clamp-ring was unable to retain the top in thirty foot drop tests of packages having the maximum allowed weight (290 kg or 640 lb). To determine if the clamp-ring closure was adequate for packages with lower contents weight, a series of tests were performed on packages weighing 147 kg (325 lb) at a range of impact angles. The results showed that the standard clamp-ring closure was unable to retain the top in tests of standard 6M packages weighing 147 kg (325 lb). A test employing a plywood disk enhanced closure with impact at 6.5 degrees retained its top successfully.

Description: Shipping of materials between different locations requires methods for confirming that the correct quantities and materials are shipped and received intact. The quickest method for confirming the correct quantity of material is to weigh the material on a balance. In order for the shipper's and receiver's balances to agree, the balances must use a traceable method of periodic calibration. Once calibrated, the balances must be rechecked periodically with accepted standards to confirm that the balances remain within the allowable tolerances. This letter affirms that the balances used for weighing 3013 containers and 9975 shipping packages are staying within allowable accepted tolerances and that there is no discernable ''drift'' in the weighings that might indicate future trouble with the balance.
