Background: Several reservoir systems have been constructed for hydropower generation around the world. Hydropower offers an economical source of electricity with reduce carbon emissions. Therefore, it is such a clean and renewable source of energy. Reservoirs that generate hydropower are typically operated with the goal of maximizing energy revenue. Yet, reservoir systems are inefficiently ope...

The thickness of the lining is reduced from 230 mm to 80 due long-term wear, resulting in low thermal efficiency rotary kiln. resistance, which positively correlated with lining, one most important factors determining kiln can be improved by introducing insulation material lower conductivity into lining. average heat flux used as evaluation index 4×60 m under no-load conditions this work. A num...

BACKGROUND Previous studies have shown that the expression and distribution of keratinocyte growth factor (KGF), also known as FGF-7 (fibroblast growth factor-7) or HBGF-7 (heparin-binding growth factor-7), may be implicated in kidney cyst formation and expansion. However, there are no data on KGF expression in human autosomal dominant polycystic kidney disease (ADPKD) tissue, and it is unknown...

Background: Neem leaves (Azadirachta indica L.) have been used for many therapeutic purposes and medicinal applications. The extract of this plant has been used in both male and female genders as a traditional agent to prevent early pregnancy. In this study, the effect of this extract was investigated histologically and morphometrically on the germinal epithelia of the seminiferous tubules, epi...

Lung disease is the major cause of death in individuals suffering from cystic fibrosis (CF), with abnormal lung-lining fluids occurring already in early infancy. However the precise aetiology of CF lung disease is still poorly understood. We investigated the structural components of the airway surface-lining layer in targeted Cftr/Cftr mutant mice and non-CF controls. Five lungs per animal grou...
