[1] Models of hydrothermal groundwater circulation can quantify limits to the role of hydrothermal activity in Martian crustal processes. We present here the results of numerical simulations of convection in a porous medium due to the presence of a hot intruded magma chamber. The parameter space includes magma chamber depth, volume, aspect ratio, and host rock permeability and porosity. A prima...

An inexpensive controlled drug infusion system based around 80C85 microprocessor with RAM, EPROM and peripheral interface devices is developed. In this system, the drop rate selection is done by BCD thumb wheel switches from 1 to 99 drops/min, LCD display is used for displaying the parameters settings, number of drops infused and various alarms messages for patient safety and unique drop sensin...

a crossbreeding experiment involving four iranian fat-tailed sheep breeds, namely kurdi (k), chaal (c), afshari (a) and sanjabi (s) was carried out to determine the ram breed effects on productivity of kurdi fat-tailed ewes (k) under extensive production system. a total of 475 kurdi ewes were mated to 24 rams from four breeds producing 454 lambs including pure kurdi, kk, (116 lambs), afshari × ...

Background: Researchers have indicated that mammalian spermatozoa are characterized by a high proportion of saturated, n-6 and n-3 series of fatty acids (FA). Major FA in rams’ sperm consists of C16, C18:1 and C22:6 (DHA). Little information exists on the effective use of saturated and unsaturated FA for ram whereas lipids have important role in sperm fertility. Our Background was to determine ...

Vane oompressors can not maintain contact between a vane tip and a cylinder wall under start-up operation since backpressure acting on the vane is not sufficient. We theoretically analyzed transient behavior of the vane under the start-up operation by taking account of changes of the backpressure and discharge pressure after compression starting. The validity of the theoretical analysis was con...

The quality of extrusion welding in the extruded hollow shapes is influenced significantly by the pressure and effective stress under which the material is being joined inside the welding chamber. However, extrusion welding was not accounted for in the past by the developers of finite element software packages. In this study, the strength of hollow extrusion profile with seam weld produced at d...

This study analyzed the economics of feeding dried poultry droppings as supplement in ram production. Gross margin analysis and profitability ratio was used to analyze the data collected. The result of the budgetary analysis revealed that highest total cost of ₦5292.98/ram was incurred, highest total revenue of ₦7565.40/ram, highest gross margin of ₦3272.41/ram and highest net farm income of ₦2...

Beam transport in plasma channels is a transport mechanism especially suited for the transport of high current beams or beams of poor quality (e.g. large momentum spread). It is currently studied as an alternative to ballistic focusing for final transport in ion beam driven inertial fusion reactors. Plasma channels are created by a discharge in a background gas. The channels can be initiated ei...
