Stirred vessels are used to facilitate mixing processes across a wide range of industries. Their performance can often be predicted with certain characteristics the agitator, like dimensionless power and flow numbers. Since there exists large number agitator designs geometries, it is desirable able predict these using models rather than rely on previous experimental data. In this study, we use ...
Older adults frequently suffer from sleep disturbances. In addition, with increasing age such disturbances may accompany mild cognitive changes that are symptomatic of a range of neurodegenerative conditions. There is increasing evidence that sleep may represent a prodromal symptom, risk factor or agitator of further decline in cognitive functioning of the older adult. Current research is focus...
Piroxicam has two different crystalline forms (known as needle and cubic forms), that they are different in physicochemical properties such as biological solubility. In the current research, using Taguchi experimental design approach the influences of five operating variables on formation of the piroxicam polymorph shapes in recrystallization were studied. The variables include type of solvent,...
Objectives: Physical activity in late life may be a continuity of activity pattern in the early stages of life. The current study aimed to assess physical activity levels in former Iranian sportsmen and athletes, in 2016. Methods: This cross-sectional study used convenience sampling method to select 223 former Iranian sportsmen and athletes living in Tehran City, Iran. Informed consents were o...
Studies show that excessive rotation of rice, when the grains revolve inside the milling chamber, increase the breakage. Ease of grain movement in the milling chamber could minimize this problem by utilizing screw conveyor at the first part of rotor. In this study the rotor of a conventional milling was equipped with a screw conveyor. The effects of two rotor types (modified and conventional ro...
