Knowledge of droplet behavior is one of the most important criteria for determination of mass transfer kinetics for choosing the type of liquid-liquid extraction columns. Mean drop size data of dispersed phase droplets in continuous phase have been obtained for Various Rotary Agitated Liquid-Liquid Extraction Columns . The effects of operational variables such as mass transfer directions with a...

Natural clinoptilolite was studied to assess its performance in removing caesium and strontium ions, using both static columns an agitated tube reactor (ATR) for process intensification. Kinetic breakthrough curves were fitted the Thomas Modified Dose Response (MDR) models. In columns, adsorption capacity (qe) 200 ppm ion concentrations found be ~171 16 mg/g strontium, respectively, highlightin...

BACKGROUND Depression with psychomotor agitation (PMA; "agitated depression") is a putative psychiatric phenotype that appears to associate with some forms of substance dependence. However, it is unclear whether such relationships extend across different substances and independent (I-MDE) versus substance-induced (SI-MDE) subtypes of major depressive episodes. METHOD We examined whether lifet...

polygalacturonase production under different shear stress environments by aspergillus sp. was studied. it was found that the rate of enzyme production in the stirred tank fermentor decreased with increasing the stirrer speed in the range 300-750 rpm. on the other hand, in a split cylinder air-lift fermentor, the rate of polygalacturonase production slightly increased with increasing in air rate...

It is difficult to fully assess an agitated patient, and the complete psychiatric evaluation usually cannot be completed until the patient is calm enough to participate in a psychiatric interview. Nonetheless, emergency clinicians must perform an initial mental status screening to begin this process as soon as the agitated patient presents to an emergency setting. For this reason, the psychiatr...

OBJECTIVE Emergency physicians often need to control agitated patients who present a danger to themselves and hospital personnel. Commonly used medications have limitations. Our primary objective was to compare the time to a defined reduction in agitation scores for ketamine versus benzodiazepines and haloperidol, alone or in combination. Our secondary objectives were to compare rates of medica...
