Nanostructures of magnesium oxide is one of the most attractive materials which have shown various applications in many aspects of industries. So, finding a controllable and inexpensive technique to produce desirable nanostructures of MgO is valuable. In this work, magnesium oxide (MgO) with different morphologies was successfully prepared via a simple solid-state method. The molar ratio of sod...

background brucellosis is a zoonotic disease that is endemic in iran. appropriate and rapid diagnosis has a vital role in public health improvement. low isolation rate of the organism has reported frequently in various reports. the present study was conducted to determine the isolation rate of organism in culture from collected specimens of hospitalized patients who were not under antibiotic th...

the effect of stationary liquid media to improve shoots elongation in date palm cv. najda and an in vitro pre-acclimatization stage to increase the survival ercentage of plantlets in the greenhouse was investigated. two basal liquid media were tested: full strength and half strength murashige and skoog medium (ms). media were devoid of plant growth regulators (pgrs), containing 0.5 mg/l 6-benzy...

Knowledge of the highly regulated processes governing the production of flagella in Bacillus subtilis is the result of several observations obtained from growing this microorganism in liquid cultures. No information is available regarding the regulation of flagellar formation in B. subtilis in response to contact with a solid surface. One of the best-characterized responses of flagellated eubac...

The transient thermal response of a packed bed is investigated analytically. A local thermal nonequilibrium model is used to represent the energy transport within the porous medium. The heat flux bifurcation phenomenon in porous media is investigated for temporal conditions and two primary types of heat flux bifurcations in porous media are established. Exact solutions are derived for both the ...
