CD nozzle , to increase the velocity of air coming through it . A throttle valve exists below the venturi to control the airflow , either to restrict or block the air intake . This enables the control of air /fuel mixture inside the system thus regulating the power and speed of the engine . The control of the throttle comes from a mechanical linkage of joints and rods to the accelerator , usually a pedal or an equivalent control of a vehicle or equipment . The...

In to determine the average hardness of the lining , the micro-hardnesses of the different metallic phases are measured (Stadler et al , 2007 . The friction layer of a disk brake is a two-layer structure of iron and copper oxides . It is heterogeneous , uneven in its thickness , and with iron oxides as a lower layer and a copper oxides layer on top...

In such dry environments , soil water movement is driven largely by evaporation and occurs in an upward direction by capillary action . These strategies can be used in different regions including natural grassland in Argentina . The benefit of these solutions is that they can be implemented locally and do not need additional funding or outside financial support . Soil salinity and sodicity...

This happens as newly extrusion materials push the old ones sideways . Though the old materials are rather heavy to withstand the push , the pressure is so high to resist . Any possible resistance from several places in the material leads to pressure moving to weaker areas and eventually release materials on ocean surfaces . The pressures for new materials from down the...
