Due to surface tension, a beading instability takes place in long enough fluid column that results the breakup of and formation smaller packets with same overall volume but area. Similarly, soft elastic cylinder under axial stretching can develop an if tension is large enough. This occurs when force reaches maximum fixed or force. However, unlike situation fluids where develops finite wavelengt...

Results from biochemical and structural studies of the RSC chromatin-remodeling complex prompt a proposal for the remodeling mechanism: RSC binding to the nucleosome releases the DNA from the histone surface and initiates DNA translocation (through one or a small number of DNA base pairs); ATP binding completes translocation, and ATP hydrolysis resets the system. Binding energy thus plays a cen...

What are the causes of cervical myelopathy? Myelopathy is caused by any pathologic process that interferes with transmission of signals through the spinal cord. In regard to orthopedic surgery, the most common cause of this disease is due to cervical degenerative disc disease putting pressure on the spinal cord in a condition referred to a cervical spondylotic myelopathy. The remaining referenc...

Diastolic pressure-length relationships of an ischemic region of the canine left ventricle were measured over a six-hour period following left anterior descending coronary artery ligation, and their evolution was compared with the extent of systolic aneurysmal bulging. Normalized ischemic segment length excursion, which after coronary artery ligation may be taken as a measure of systolic aneury...

Light-weight and high strength alloys such as Al-Mg alloys are used in order to reduce the weight of industrial components. However these materials should be formed at elevated temperatures due to their poor formability at room temperature. Hot metal gas forming is one of the high-tech forming processes that is used to solve this problem. Recent investigation on tube hydroforming showed positiv...
