[Purpose] The purpose of this study was investigated the effect of tight clothes on cervical and thoracic spine muscles activities during shoulder abduction. [Subjects and Methods] The subjects of this study were 10 healthy males. The subjects performed two shoulder abduction trials for each of two jacket-wearing conditions. The right upper, middle, and lower trapezius and serratus anterior mus...

explosion and fire on an offshore rig can lead to its minor or complete damage and sinking which means the loss of life or environmental pollution. hence the use of techniques such as blast wall is crucial to reduce the detrimental effects. these blast walls are designed for explosion wave of length between 0.1 to 1 of load mainly to protect the personnel and critical sections. in this research...

Indefinites in intensional contexts, such as attitude reports or intensional argument positions, give rise to a well-known ambiguity. Consider (1): On the so-called specific reading, it says that there is a particular object which happens to be a jacket like Malte’s jacket such that Adrian wants to buy that particular object. Adrian need not know that that object is a jacket like Malte’s. On th...

In the seismic risk assessment of structures, two main random variables are involved, namely the vulnerability of the structure and the seismic action. The aim of the study presented here is to analyze the seismic behavior of the jacket-type offshore platforms as an expensive and vital structure. Furthermore, the influence of the incidence angle of the seismic action is also investigated by usi...

Laboratories and test houses keep a "pool" of test subjects that volunteer to be participants in life jacket approval testing, which is believed to be an incorrect procedure. Fifty-six participants donned 8 child/infant life jackets onto 4 infant manikins in random order with time and accuracy of donning recorded. Average donning time for all 8 life jackets decreased significantly after the fir...
