Cellular structures are commonplace in engineering applications, such as aerospace and medical engineering, because material-air composites offer significant mechanical benefits, for example due to improved weight-to-strength ratio. Typically, cellular based on patterns of periodically repeating unit cells, squares or hexagons, but the periodic nature available symmetries give rise anisotropic ...

Cement manufacturing is one of the most energy intensive processes and is accountable for substantial pollutant emissions. Increasing energy costs compel stakeholders and researchers to search for alternative options to improve energy performance and reduce CO2 emissions. Alternative fuels offer a realistic solution towards the reduction of the usage of fossil fuels and the mitigation of pollut...

the major purpose of the present this study is to reviews the classifications of approaches to religious education, and introducing an alternative classification of religious educator theory. to this end, approaches to islamic education which have been categorized typologically and are associated with the cognitive context of iranian intellectuals have been studied. in line with this goal, the ...

BACKGROUND This paper describes the rationale, implementation and operation of a "world first" Islamic inspired methadone maintenance treatment project delivered in a mosque setting and presents the outcome for the first group of participants. The project explored the viability of expanding addiction recovery services through the network of mosques in Muslim communities. METHODS The project c...

casing soil is one of the most important indicators of button mushroom production, which has a direct impact on the size and performance. due to the easy availability of resources for the production of vermicompost this mix can be used alternative of peat to button mushroom production. this study was conducted with nine treatments and three replications in¬¬ a completely randomized design at th...

New emerging issues appears regarding the possible aerosolization of micro-organisms from biofilters to the ambient air. Traditional bioaerosol sampling and cultural methods used in literature offer relative efficiencies. In this study, a new method revolving around a particle counter capable of detecting total and viable particles in real time was used. This counter (BioTrak 9510-BD) uses lase...

The strategic capacity planning function must be a core competency for firms in capitalintensive, long equipment lead-time industries such as the semiconductor industry. Major investment decisions are made years in advance of forecasted demand, and involve a complex array of product design and manufacturing parameters. The high stakes and breadth of uncertainty require a well-orchestrated, comp...

Modeling of a manufacturing system enables one to identify the effects of key design parameters on the system performance and as a result to make correct decision. This paper proposes a manufacturing system modeling approach using a spreadsheet model based on queuing network theory, in which a static capacity planning model and stochastic queuing model are integrated. The model was used to impr...

Advanced Resources Planning hits the bottom of what we know as aggregate planning. This approach differs from other approaches in the way that it explicitly recognizes the stochastic nature of manufacturing systems. Therefore it is an ideal high level tuning and planning tool which can be used in various planning environments like MRP, ERP, JIT, Load Oriented Planning, Theory of Constraints, Fi...
