Hole cleaning for the majority of vertical and directional drilling wells continues to be a substantial difficulty despite improvements in fluids, equipment, field techniques, academic industrial research. Poor hole might cause issues such as stuck pipe incidents, cuttings accumulation, torque drag, erratic equivalent circulating density annulus, wellbore instability, tight spots, condition iss...

Knowledge concerning SS (homozygous for the beta s gene) red blood cell (RBC) heterogeneity has been useful for understanding the pathophysiology of sickle cell anemia. No equivalent information exists for RBCs of the compound heterozygote for the beta s and beta c genes (SC) RBCs. These RBCs are known to be denser than most cells in normal blood and even most cells in SS blood (Fabry et al, J ...

omentin-1 is a novel adipokine that is predominantly secreted by visceral adipose tissue. circulating levels of omentin-1 is inversely related to obesity. there is limited information about the effect of exercise training on serum omentin-1 concentration. the aim of this study was to investigate the effect of four weeks of progressive resistance training on serum omentin-1 levels. 16 male wiste...

High power density outer-rotor motors commonly use water or oil cooling. A reasonable thermal design for outer-rotor air-cooling motors can effectively enhance the power density without the fluid circulating device. Research on the heat dissipation mechanism of an outer-rotor air-cooling motor can provide guidelines for the selection of the suitable cooling mode and the design of the cooling st...

The social environment can alter mating tactic expression through modulatory effects on the endocrine system. In anuran amphibians (frogs and toads), males often adopt noncalling mating tactics in response to increased chorus density, but the underlying physiological factors mediating this response are poorly understood. Recent models suggest that density-dependent expression of alternative mat...
