Do distinct male morphs use the same ornaments in different ways? Female preference for UV ornamentation and male activity was examined in two different male size classes of the swordtail Xiphophorus nigrensis: intermediate and large. UV ornamentation is preferred by females for both size classes, while high male activity is not. Large males have significantly greater intensity and saturation o...

All U.S. Army class A and B mishaps of four types of helicopters occurring from 1 October 1979 through 30 September 1985 were reviewed. During this 6-year period, there were 298 crashes involving 303 aircraft. There were 1,060 individuals aboard the crashed aircraft and 611 were injured, 136 fatally. The most common cause of injury was the "secondary impact" caused by collapse of structure into...

The authors present the case of a chondrolipoma which was excised from the left hand's palm of an 83-year old woman. Chondrolipomas are rare neoplasms; their terminology and pathogenesis have been controversial in the past. Chondrolipoma in the hand does not seem to have been reported so far. The present case thus expands the spectrum of neoplasms known to arise at this anatomical site.

An experimental study was performed to investigate the effects of the body angle of attack on the tail surface pressure distribution for a half body-tail combination in subsonic flow. The results show, in small deflection angle regions, that the tail deflection has the same effect on the surface pressure as the body angle of attack. However at moderate to high deflections, the flowfiled caused ...

• Time-series analyses were used to characterize internal temperature dynamics from different regions of decomposing remains. The chest region experienced the highest average temperatures, and mouth maximum temperatures. Differences in temperatures suggest location blowfly larvae be noted improve accuracy development estimates. decomposition vertebrates is controlled largely by external tempera...

background: musculoskeletal disorders represent a substantial cause of morbidity worldwide. the contribution of work to these disorders has been well established by various epidemiological and laboratory-based researches. the aim of this study is to investigate the prevalence and associated factors of musculoskeletal disorders in truck drivers. materials and methods: this cross sectional study ...

Reproductive parameters evaluation is considered as helpful tool for gene bank formation in ecological and economically important animals species. Gloydius halys caucasicus is venomous, viviparous pit viper of northwest of Iran. In this research, the spermatic reproductive parameters of this taxon were studied. Twenty six male snakes were collected from Takht-e-Soleiman region between September...
