the oil content of the wax produced in a dewaxing process is the key economic parameter thatshould be reduced as much as possible. some factors such as the type of solvents, cooling rate,temperature, and solvent to oil ratio influence the dewaxing process. due to the fact that crude oildiffers from place to place and since the operational conditions for wax extraction vary for differenttypes of...

manoeuvre, is one of the principles of war in most of the world’s armies. mobility and manoeuvre of the operational and support forces in the battle fields occur in bed of natural and cultural geographic factors, i.e, avenue approach and frontier transportation networks. so for this reason analyzing this geographical factors in skills such as line identification in tactical and operational leve...

Operational excellence is generally known as a management system integrated across critical functions that is geared towards continually improving operational performance. Functional areas such as health, environment and safety, quality and human resources are the focus of many corporate-wide operational excellence programs. Operational excellence also focuses on improving areas such as custome...

this article proposes a direct method for solving three types of integral equations with time delay. by using operational matrix of integration, integral equations can be reduced to a linear lower triangular system which can be directly solved by forward substitution. numerical examples shows that the proposed scheme have a suitable degree of accuracy.

A study on capstan partial pressure suits (PPSs) was conducted to determine their effects on pilots' operational performance on a series of ergonomic measures at different pressure levels using objective and subjective approaches. Tests of range of motion, operational performance and operational strength were carried out on ten male subjects wearing PPSs under 6 different pressure conditions. S...

The performance gap between hospital spending and outcomes is indicative of inefficient care delivery. Operational failures—breakdowns in internal supply chains that prevent work from being completed—contribute to inefficiency by consuming 10% of nurses’ time (Hendrich et al. 2008, Tucker 2004). This paper seeks to identify organizational factors associated with operational failures, with a goa...

BACKGROUND Playing-related musculoskeletal disorders (PRMDs) are a recognized problem amongst instrumental musicians. Although pianists are prominent in data regarding prevalence of PRMDs, there is poor understanding of piano-specific risk factors associated with PRMDs. AIM To synthesize published literature on the prevalence of and risk factors associated with PRMDs in pianists. METHODS Th...
