Tuberculosis (TB) remains one of the main causes of human death around the globe. The mortality rate for patients infected with active TB goes beyond 50% when not diagnosed. Rapid and accurate diagnostics coupled with further prompt treatment of the disease is the cornerstone for controlling TB outbreaks. To reduce this burden, the existing gap between detection and treatment must be addressed,...
The use of rectal balloon in radiotherapy of prostate cancer is shown to be effective in reducing prostate motion and minimizing rectal volume, thus reducing rectal toxicity. Air-filled rectal balloon has been used most commonly, but creates dose perturbation at the air-tissue interface. In this study, we evaluate the effects of rectal balloon-filling materials on the dose distribution to the t...
In this paper, the performance of a two-phase closed thermo-siphon (heat pipe) with water as the working fluid for thermal control of a batch reactor was studied. In the simulation performed, the influence of some parameters such as: filling ratio of 30%-80% and input heat power between 200- 1200 watt and heating time on the uniformity of the temperature distribution in the reactor were studied...
Kariro Pb prospect area, which is located in northwest of Boshruyeh, occurs as vein-veinlets, open space filling, and cement of fault breccia in Middle Jurassic metamorphosed shale (slate) unit of Baghamshah Formation. Mineralization zones contain dolomite (70-85%) and galena (0.5-2.5%) with small amounts of pyrite, quartz, and calcite. Dolomitization and silicification of host rock are the mos...
high speed wind tunnels are widely used in the study of fluid flow behavior around various objects. the air flow in the starting step of supersonic wind tunnels is transient including strong shock waves caused by the interaction of the tunnel main stream and the boundary layer at walls. to arrive in running step, the tunnel must be designed so as these waves leave immediately the test section. ...
In this paper the heat transfer characteristics of a two-phase closed thermosyphon over a wide range of heat transfer rates, system pressure, aspect ratios and filling ratios were studied. The experiments focused on the boiling and condensation heat transfer characteristics of the thermosyphon. The experimental boiling and condensation heat transfer coefficients inside the thermosyphon were com...
Airspace filling process is characterized on CT by the presence of one or more fairly homogeneous areas of consolidation with little or no volume loss. The consolidation may be segmental, subsegmental, lobular, or acinar (10 mm or less in diameter). Poorly defined centrilobular nodules may be associated. The margin of the consolidation usually is poorly defined except in the areas in which the ...
In this study, fertilization, hatching and deformation rate of the eggs, and larvae obtained from hormone injected (HI) and non-injected broodstock (NHI), were determined. In the experiment, no differences were observed in the groups’ fertilization rates (p>0.05). Hatching rate was found higher in the HI group (p<0.05). During the experiment, malformations such as spinal fluid accumulation, sad...
