Convective activity occurs more commonly and frequently across the United States during the spring and summer (nominally, the period of May through September). While distribution of the activity has been examined both temporally (time of maximum activity and severity) and spatially (e.g., nationally as well as regional variations) to depict its characteristic time of occurrence and pattern, ver...

In European Robins, Erithacus rubecula, the magnetic compass is lateralized in favor of the right eye/left hemisphere of the brain. This lateralization develops during the first winter and initially shows a great plasticity. During the first spring migration, it can be temporarily removed by covering the right eye. In the present paper, we used the migratory orientation of robins to analyze the...

BACKGROUND This study tests the validity of a newly-proposed spring constant method to analyze arterial elasticity in type 2 diabetic patients. METHODS The experimental group comprised 66 participants (36 men and 30 women) ranging between 46 and 86 years of age, all with diabetes mellitus. In the experimental group, 21 participants suffered from atherosclerosis. All were subjected to the meas...

The valves in reciprocating compressors use springs to control the timing of the valve closing. These springs are subjected to dynamic loading by the motion of the valve element. The element motion is periodic, but includes rapid acceleration and deceleration. It can therefore excite a wide range of frequencies in the spring. The resulting spring surge creates high stresses and is a major contr...
