This paper presents a discussion on whistle-blowing and take the view that whistle-blowing is an important fraud detection technique. A discussion of some factors that influence the whistle-blowers’ incentive to blow the whistle or to remain silent in the face of persuasive fraud red flags, is also presented. The paper suggests that the tradeoff between the cost and benefit of whistle-blowing m...

This work analyzes energy requirements for drawing the air through a hollow-fiber membrane (HFM) during filtration. Polypropylene HFMs varying in inner fiber diameter (230 and 470?m) were used to separate ASHRAE A2 fine test dust from simulated particle laden environment. During experiments, pressure drop, permeate velocity (air flowrate), fan frequency power input recorded. The obtained experi...

The glass bead making furnace of the Masaga Glass Guild in Bida, Niger State Nigeria was evaluated comparison to those Ghana (Krobo) and India (Firozabad); it discovered that falls short an efficient system for sustainable work should facilitate appreciable productivity. Furthermore, is not built with refractory bricks, implying has a life span; operated by hand-worked traditional cloth bellows...

The U.S. National Institute for Occupational Safety and Health (NIOSH) conducted a study to determine the effectiveness of a filtered air delivery system to reduce respirable dust exposure of roof bolter operators in underground coal mines. When performing roof bolting operations, roof bolter operators may experience exposure to high levels of respirable dust during a working shift, especially ...

A ribonuclease helps the ER get in shape S chwarz and Blower reveal that a calcium-regulated ribonuclease promotes the formation of tubular ER networks. By triggering a wave of intracellular calcium, fertilization induces dramatic changes in the internal organization and protein expression pattern of oocytes. Schwarz and Blower discovered that increased calcium levels activate a ribonuclease ca...

in this work, result of experimental investigation on interaction of fuel spray generated by a swirled type injector, with air motion in a prototype cylinder are presented. experiments were carried out by planar imaging and particle image velocimetry (piv) techniques in order to provide information about the spray structure evolution and instantaneous velocity distribution of air motion and fue...
