Fluid pressure amplifier and system
A flueric beam-deflection amplifier and a method of controlling the same are described. Either a single or a series of cascaded fluid amplifier units are provided and each one of which may include the usual power nozzle, control nozzles, outlet passages and vent passages. All vent passages of each fluid amplifier unit lead to an enclosed vent outlet chamber which is connected to the ambient environment or to a return manifold through a variably restricted passage. To control the fluid amplifier unit, power and control stream pressures are first established, after which the restricted passage is reduced to regulate the input bias, the gain and the input impedance of the fluid amplifier unit
Health evaluation of free-ranging and captive pichis (Zaedyus Pichiy; Mammalia, Dasypodidae), in Mendoza province, Argentina
The health of free-ranging and captive pichis (Zaedyus pichiy) was assessed in Mendoza Province, Argentina, between November 2001 and December 2006. Postmortem examinations of 150 confiscated and vehicle-killed pichis and clinical examinations of 139 wild-caught individuals suggest that the wild populations are currently in good health. Lesions and scars were observed in a large proportion of wild-caught pichis. The most common lesions were associated with parasitism or parasite larva migration. Sarcocystis cysts were relatively common in the skeletal muscle, and Besnoitia cysts were observed in the lungs of 24 evaluated animals. Elevated ambient humidity levels often caused moist dermatitis with epidermal detachment in captive pichis. This report constitutes the first health evaluation of free-ranging and captive Z. pichiy. It will be a starting point for future health studies and will be beneficial for the captive management of this species.Fil: Superina, Mariella. University Of New Orleans; Estados Unidos.
