High-quality Fe-doped ZnS films have been fabricated by electron beam evaporation. After the doping, the fabricated films still maintain the preferential crystalline orientation and phase purity of the host ZnS. According to the observation of surface morphology, the root mean-square roughness of the samples increases slightly with the increase of doping content. All of the prepared samples are in cubic zinc blende structure of ZnS. Transmission spectrum confirms a more obvious dip near 3 μm with higher dopant concentration and it can be attributed to the typical 5E→5T2 transition of Fe2+. Fe-doped ZnS film is also successfully used for Q-switched Er:ZBLAN fiber laser.

An optimization was performed for a sintering waste heat power unit with all data obtained in the site and under the unit normal operating conditions. The physical and mathematical model for the process of cooling and generation is established, which makes the net power generation as an objective function of the cooling machine imported ventilation, the thickness of sinter and the main steam pressure. Optimizing for single parameter, we found that each parameter had an optimal value for the system. In order to further optimize the system's operating parameters, genetic algorithm was used to make the combinatorial optimization of the three parameters. Optimization results show that power generation capacity per ton is increased by13.10%, and net power generation is increased by 16.17%. The optimization is instructive to the operation of sintering waste heat power unit.

The skeletal renin–angiotensin system (RAS) is involved in the progression of osteoporosis and the active peptide within the RAS, angiotensin II (ANG II), has deleterious effects on bones. This study was performed to investigate whether suppression of the rate-limiting step of the RAS cascade by the renin inhibitor aliskiren has a benefit on trabecular bone in osteoporotic mice. A postmenopausal osteoporosis model was induced by bilateral ovariectomy. The ovariectomized (OVX) mice were treated with a low (5 mg/kg) or high (25 mg/kg) dose of aliskiren for 6 weeks. Micro-computed tomography was performed to detect trabecular bone parameters of lumbar vertebra and to obtain 3-dimensional (3D) images. Treatment with aliskiren markedly increased bone volume over total volume (p

This article according to the ShengLi Open-pit Coal Mine landslide and the slope project special details, used the FLAC numerical calculus analysis software to conduct the research to the landslide cataclysm mechanism, has carried on the optimized analysis to the reinforcement plan.Has obtained the pre-stressed anchor rope frame beam + high pressure splitting grouting reinforcement plan government landslide most superior processing plan through the numerical calculus, thus active control ShengLi Open-pit Coal Mine slope distortion destruction.

Our previous biological study demonstrated that Fructus Ligustri Lucidi (FLL), the fruit of Ligustrum lucidum Ait. (Oleaceae), could be used to maintain calcium balance and prevent age-related osteoporosis since it effectively decreased calcium loss and increased calcium retention in rats.This study investigates the combination effect of the Chinese herbal medicine FLL and a high calcium diet on calcium imbalance induced by ovariectomy in mice.The ovariectomized (OVX) mice were orally treated with vehicle, FLL extract (700 mg/kg), milk powder (5 g/mice) fortified with calcium (1.0% Ca) and the combination of FLL with milk powder. After 6 weeks of treatment, urine, serum, and tibia were preserved for biochemical analysis and kidneys were taken for gene expression analysis.The combination treatment of FLL and a high calcium diet significantly increased bone calcium content (6.80 ± 0.34 mg) by 22% (p 0.05) and decreased urine calcium excretion (0.099 ± 0.009 mg/mg) by 62% (p 0.01) as compared with those of the OVX group (bone Ca, 5.57 ± 0.31 mg; urine Ca/Cr, 0.261 ± 0.017 mg/mg). The mRNA expression of renal calcium-binding protein-9k (CaBP-9k) and calcium-sensing receptor (CaSR) in combination treatment group was significantly up-regulated and down-regulated, respectively, as compared with those of the OVX group.The beneficial effects of this combination therapy on calcium balance of OVX mice were, at least partially, attributed to its regulation on mRNA expression of CaBP-9k and CaSR in kidney.
