The oil distribution system of an automotive light duty engine typically has an oil pump mechanically driven through the front endancillaries drive or directly off the crankshaft. Delivery pressure is regulated by a relief valve to provide an oil gallery pressure of typically 3 to 4 bar absolute at fully warm engine running conditions. Electrification of the oil pump drive is one way to decouple pump delivery from engine speed, but this does not alter the flow distribution between parts of the engine requiring lubrication.

The surface of the Earth is relatively cool, but things get hotter as you descend beneath the ground. When you get about 30 km down (beneath the continents), you reach the Earth’s mantle. This is region of the Earth where rocks can be heated to more than 1,000 degrees C.

Similarly, solar thermal systems are reviewed and the most effective system described. Unlike PV technology, solar thermal technology for water pumping is lacking especially in small scale operations. However, with the possibility of local production, low investment cost, easy maintenance and lower carbon footprint, solar thermal water pumping technologies may be able to overcome the shortcomings of the PV technology that has stopped widespread use of the technology for irrigation applications.

I won’t pretend not to have a cell phone. It’s a fairly decent smart phone, even. But I don’t subscribe to the theory that having a mobile phone means I’m connected by phone whenever I’m mobile. Having finished her dissertation, Wilkinson started postdoctoral research at the University of Vienna, Austria. There, her supervisor Ludwig Huber encouraged her to pursue her interest in reptiles. In 2007 they set up the cold blooded cognition lab.

In the they were Tweedledum and Tweedledumber. In recent years, it has been said that performance enhancing drugs should be banned in sport and made compulsory for Australia federal politicians. Les Brennan, Sunshine Bay, NSW STOP THE GRAVY TRAIN I agree that the of entitlement should be over and personal responsibility should take its place, but will it happen? The worst claimers are our federal MPs.

Northrop Grumman is now controlling two Cygnus capsules in orbit, a first for the Virginia based company. Named for the swan constellation, the Cygnus launched last spring is flying free of the 250 mile high (400 kilometer high) space station, after completing its grocery run. It will be directed to a fiery re entry sometime in the near future, taking station trash down with it, according to company officials..
