The flow field generated by the flow into a jet engine air-intake, with near ground effects, is considered. The axial inflow in the neighborhood of the ground generates a system of unsteady vortices. Some of these vortices extend from the air-intake towards the ground. Some of these vortices are strong enough to dislocate and even lift small objects from the ground up to the air-intake. The dynami

Studies the origin of the Inventio Crucis legend: the historical events behind it as well as its textual sources and antecedents. A literary interpretation of the text is then attempted, showing that the legend is influenced by Jewish traditions and adversus Iudaeos treatises.

Biogas production through anaerobic digestion in sync with other bio energy production technologies could replace or partially replace fossil fuels and hence curb greenhoAnaerobic digestion provides an array of positive environmental benefits such as reducing greenhouse gas emissions, replacing mineral fertilizers, producing renewable energy and treating waste. However, pitfalls in anaerobic digestion such as poor methane yields, process instability, process failure and regional shortages of feedstock have limited the full exploitation of the anaerobic digestion p

Both systems had an effect on speed and the effect was greater for the Active Accelerator Pedal than f
