introduction: lasers, light emitting diodes (leds) and super luminous diodes (slds) are widely used to treat selected musculoskeletal, integumentary and neurological conditions. the mechanisms underlying the reported treatment effects of light therapy are unclear and the physiologic effect of light on a variety of tissues, particularly neurological, is mostly unknown. a few researchers have rep...

in this research, a cold model of internally circulating fluidized bed is investigated. the aim is to find the effects of some of the operating parameters on the performance of the reactor. experiments were carried out in a glass column (30 mm i.d. and 25 cm height) with a centrally located draft tube (11 mm i.d. and 5 or 7 cm height). the bed was loaded with white silica particles (dp = 0.15 -...

multiphase impeller stirred tank reactors enhance mixing of reacting species used in a variety of chemical industries. these reactors have been studied based on computational fluid dynamics (cfd) that can be used in the analysis, design and scale up of these reactors. most of the researches done in this area are limited to single phase reactors, and a few remaining two phase flow investigations...

background: heat therapy is one of the natural treatments that can affect the information transferred by the proprioceptive receptors. heat has an effect on the conduction velocity of peripheral nerves, but the exact effect of two kinds of deep and superficial heat on the joint position sense is not known clearly. the present study aimed to compare the effect of deep and superficial heat on ank...

The seepage velocity and temperature externally manifest the changing structure, gas desorption and energy release that occurs in coal containing gas failure under loading. By using the system of coal containing gas failure under loading, this paper studies the law of seepage velocity and temperature under different loading rates and at 1.0 MPa confining pressure and 0.5 MPa gas pressure, and c...

CO radio line observations reveal a molecular gas envelope around the peculiar star HD101584 with characteristics very similar to those of wellknown young post-AGB objects. We estimate that there is at least 0.1 M of molecular gas, very likely remnant gas from a former AGB-envelope. This gas has been efficiently accelerated to very high velocities (>50 km s−1, and a significant fraction to >100...

The removal of hydrogen sulfide (H2S) from airstreams was studied in a biotrickling filter packed with porous lava as a carrier of Thiobacillus thioparus (DSM5368) with counter current flows of the air and liquid streams. The effect of operating parameters on biotrickling filter performance was studied. Experiments were performed at different empty bed residence times (9-60 sec), and...

Figure 1. Model of P-wave velocity (above) and density (below) verses gas saturation for a sandstone reservoir with a porosity of 25%. The velocity was modelled using Gassmann’s equation (1951) with the Reuss average moduli of the fluids. For a gas saturated reservoir, a decrease in gas saturation causes a negligible change in the P-wave velocity for saturations above 20% and more significant c...

We report a closed genome sequence of group A Streptococcus genotype emm3 (GAS M/emm3) strain STAB902, isolated from a superficial pyodermatitis. The genome is composed of 1,892,124 bp, 6 integrated prophages, and has 1,858 identified coding sequences (CDSs). It has been fitted with the two available invasive GAS M/emm3 strains.

Low grade sulfide ores are difficult to process due their composite mineralogy and fine grained dissemination with gangue minerals. Therefore, grinding of such becomes essential liberate valuable In this research, selective flotation was carried out using two pitched blade turbine impellers diameters 6 cm 7 float copper nickel. The main focus research generate optimum hydrodynamic conditions th...
