ABSTRACT Background Recent findings indicate that there is a body weight–sensing homeostatic regulation of body weight in postpubertal rodents and humans. It is possible that body weight sensing also might be involved in the regulation of pubertal timing. Although an early small study suggested that there is a critical body weight for pubertal timing in girls, most studies have focused on BMI and reported an inverse association between BMI and pubertal timing. Objectives In the present longitudinal well-powered cohort study, we revisited the critical weight hypothesis and tested if prepubertal body weight is a more robust inverse predictor of pubertal timing than prepubertal BMI in boys. Method We included men born during 1945–1961 (old cohort; n = 31,971) and men born during 1981–1996 (recent cohort; n = 1465) in the large BMI Epidemiology Study (BEST) Gothenburg (combined BEST cohort n = 33,436). Men with information on prepubertal body weight and BMI at 8 y of age and age at peak height velocity (PHV; an objective measure of pubertal timing) were included. Results Body weight explained more of the variance in age at PHV than BMI in both the old cohort and the recent cohort (combined cohort, body weight 6.3%, BMI 3.6%). Both body weight (β: −0.24 SD/SD increase in weight; 95% CI: −0.25, −0.23) and BMI (β: −0.18 SD/SD increase in BMI, 95% CI: −0.19, −0.17) were inversely associated with age at PHV but the association for body weight was significantly more pronounced than the association for BMI (P < 0.001). Conclusions In conclusion, prepubertal body weight is a more robust inverse predictor of pubertal timing than prepubertal BMI in boys. We propose that body weight sensing constitutes a feedback mechanism to regulate pubertal timing.

Abstract Under the locomotive cab occupant protection research program sponsored by the Federal Railroad Administration (FRA), Sharma & Associates, Inc. (SA) developed a Secondary Impact Protection System (SIPS) for locomotive engineers. The system uses a large, automotive-style, passenger airbag in combination with a deformable knee bolster to provide the level of protection needed for the locomotive engineer, without compromising the normal operating environment and egress. A prior version of the system [1] was prototyped and tested in a dynamic sled test with a 23g crash pulse and was shown to meet most limiting human injury criteria defined in the Department of Transportation (DOT)’s Federal Motor Vehicle Safety Standards (FMVSS 208) [2] for the head, chest, neck, and femur. The system also showed marginal performance for the chest injury index and indicated potential for an improved airbag design to fully meet all requirements. In the current study, simulations with an optimized airbag and higher capacity inflator system showed that SIPS can provide excellent occupant protection for an unbelted locomotive occupant in a frontal crash. Sled testing of SIPS confirmed the performance, and the system successfully met all eleven (11) criteria of the FMVSS 208 standard [2]. The shape and position of the airbag module and its attachments to the desk were generally the same as those presented in previous research. The key changes that helped meet all criteria were the higher capacity inflators, knee bolster system brackets moved forward, thicker knee plate, higher volume airbag and additional vents.

Production Tolerance

Most of industries in our area are still using old techniques to measure the quality of their products. These old ways of measuring the quality are not applicable for every product and the checking is only by random samples. This method may affect the company if more products are out of production tolerance. So, this project is to design and fabricate weight sensing system that can be used in a production line in which the system can accept a specific weight to go in production line and reject others. The idea of this project comes after seeing the effects of going out of weight tolerance for some products that require quality. So, this report will screen the previous works and technologies which are related to the topic in literature review chapter to get benefits from them and avoid mistakes. No specific literature was identified with complete design of automatic weight sensing system. Personal interaction with the Reem batteries and power appliances results in the generation of the idea for designing and developing light weight sensing system. This project has faced some challenges which are: To identify a sensor that is having more sensitivity for the light weight and the method to amplify its low signal. These challenges have been solved by searching from different sources to get the best weight sensor and the suitable amplifier.
