Six men handling barley were followed up over two working days and their flow volume curves were measured every two hours. All experienced falls in ventilatory capacity of up to 800 ml with changes in the shape of the flow volume curve in five men. Five volunteers not previously exposed to barley dust sat in a silo for two hours. Decreases in ventilatory capacity ranging from 200 ml to 800 ml w...

We consider a manufacturing system that uses Automated Guided Vehicles (AGVs) for material handling. Increasing the capacity of the AGVs used can lead to increased throughput and reduced inventory-holding costs. However, AGVs are typically expensive. Hence modeling the economics of buying an additional vehicle is an important problem from the standpoint of making a system lean. Optimization of ...

H ypokalemic paralysis can occur primarily as a result of an enhanced shift of potassium ions into cells or secondarily from excessive potassium loss. It typically involves proximal muscles in a symmetric fashion. We describe a patient with asymmetric distal weakness that turned out to be due to hypokalemia and responded to potassium replacement. A 65 year old gentleman woke up one morning to f...

electrospinning is a method of nanofiber filter media production. by this method, it is possibleto produce media with nanofiber in the range of nanometer to micrometer. nanofibrous media provide a large specific surface area in a finite volume thus they are suitable for filtration applications. in this study, nanofiber non-woven membranes production of nylon-6 by electrospinning method is inves...
