Different control strategies of bed temperature and moisture were investigated using various inlet air temperatures and air fluxes in both the ordinary packed bed bioreactor (without cooling water in the jacket) and the bioreactor with cooling water in jacket. The experiments were carried out within a 1-L solid-state packed bed bioreactor in which Aspergillus niger was cultivated on wheat bran....

several methods are used to decrease seed drying time and enhance the quality of dried seeds. influidization methods, good aeration occurs during the drying process. in this research, conditioned seedswith 20% d.b. moisture content were dried at 30°, 40°, 50° and 60°c using three bed conditions (fixed,minimum fluidized, fluidized). all experiments were done using a batch-type fluidized bed drye...

It is recognized that microorganisms inhabiting natural sediments significantly mediate the erosive response of the bed ("ecosystem engineers") through the secretion of naturally adhesive organic material (EPS: extracellular polymeric substances). However, little is known about the individual engineering capability of the main biofilm components (heterotrophic bacteria and autotrophic microalga...

Background There are numerous barriers to early mobilization (EM) in a resource-limited intensive care unit (ICU) without a specialized team or an EM culture, regarding patient stability while critically ill or in the presence of medical devices. We hypothesized that ICU physicians can overcome these barriers. The aim of this study was to investigate the safety of EM according to the Maebashi E...

• Vortex flow reactor was successfully assessed for monoclonal antibody adsorption. can treat cell culture broth without prior treatments. achieves a high concentration, recovery, and purity of antibodies. Fluid hydrodynamic behavior established in the corresponds to plug flow. The vortex (VFR) be used many chemical engineering applications. This paper assesses its novel use purification antibo...

abstract one of the most frequently encountered cases of rapid varied flow is the hydraulic jump. it occurs when a supercritical open channel flow changes into sub critical flow. in the present research, the experimental study of the hydraulic jump on seven sinusoidal corrugated beds with different wave steepness. the wave steepness of sinusoidal corrugated beds is in the range of 0.1667 to 0.7...

objective: zayandehrood habitat has economical and environmental importance in central plateau of iran    and it performs a vital role for habitants, agriculture section and the industries which are located along river bed. so current research  has been done to measure the contamination of heavy metals, its changes along the river route and defining the important and effective regions on this c...

background:infant mortality is often used as a standard measure of a population’s health. until cause of sudden infant death syndrome is unknown (sids), the best strategy to decrease sids, is programming to decrease facing with risk factors. the aim of this study was to find the sids risk factors among families during their child care in iran. the study is the first in iran to examine the risk ...

the effect of a combined system of the bed suction and jet injection as a pier-scour countermeasure on the turbulent flow field is studied in a laboratory flume using an acoustic doppler velocimeter (adv). the three components of the velocities in the vertical symmetry plane in the equilibrium scour hole in front and rear of the pier under 3-jet injections and bed suction rate qs/q0 = 2%located...
