Coal washing plants are usually f.d f.om various sources. Coals include dif.erent combinations which should be considered f.r increasing the plant prof.ciency. Thus dif.erent methods have been used to enrich various coal types. In this study, Alborz-Sharghi coal washing plant was investigated which is f.d f.om f.ve coalmines. The optimum recovery was achieved f.r all coal types individually through experimental design. The controllable operation parameters in the experiments were collector dosage,f.other dosage, solid percent content and particle size. The other parameters such as impeller speed,pH, conditioning time and f.otation time were kept constant f.r all experiments. The optimum combination of.coals was also specif.ed. The results show that the optimum recovery f.r coal blends is 91.2%which shows much improvement relative to the plant conditions.

The applicatio n of.nano particles as selective drug delivery platf.rms arises as one the most promising therapeutic strategies in the biomedical f.eld. Such systems can encapsulate drugs, prevent its premature degradation, transport and promote the drugs specif.c delivery to the target site. Among the dif.erent nanostructures, gold-core mesoporous silica shell (AuMSS) nanorods have been one of.the most explored due to their unique physical and chemical properties. The mesoporous silica biocompatibility, high surf.ce area that can be easily f.nctionalized, tubular pores that can store the drugs, conj.gated with the intrinsic capacity of.gold nanorod to absorb near-inf.ared radiation, allows the combination of.hyperthermia (i.e., photothermal ef.ect) with drug delivery, making them a nanoplatf.rms with a huge potential f.r cancer therapy. Nevertheless, the successf.l applicati on of.AuMSS nanoparticles as an ef.ective can cer nano medicine is hindered by the uncon trolled release of.the therapeutic payloads, limited blood circulation time and unf.vorable pharmacokinetics. In this review, an overview of.the modif.cati ons perf.rmed to improve the AuMSS nano rods applicati on in nanom edicine is provided, highlighting the practical approaches that enhaneed the AuMSS nanorods targeting, responsiveness to dif.erent stimuli, and blood circulation time. f.rther, the basics of.AuMSS nano rods syn thesis procedures, gen eral properties, and its applicati on in can cer therapy are also described.

With regard to automotive traf.ic, a tunnel-type semi enclosed atmosphere is characterized by a higher concentration of.gaseous pollutants than on urban traf.ic roads and highlights the gaseous ef.luent species having an impact on material degradation. Theref.re, a transverse approach between air quality and its consequences upon the longevity of.materials is necessary, implying better knowledge of.tunnel atmosphere and a better understanding of.material degradation inside a tunnel f.r operating administration. Gaseous pollutant measurements carried out in a road tunnel in Rouen （Normandy） give the real world traf.ic concentrations of.experimental exposure conditions. The sampling campaigns, achieved in summer and winter include SO2, NO2, BTEX and aldehyde analyses. Ef.luent prof.les in the upward and downward tubes have been established. The current work shows that SO2, NO〉 f.rmaldehyde, acetaldehyde, propanal and butanal must be considered in the degradation process of.materials in a stuf.y environment. As regards NO,, its concentration depends on the modif.cation of.the automotive f.eet. The total aldehyde concentrations indicate no particular trend between the two bores. f.rmaldehyde, acetaldehyde, propanal, butanal and acrolein species are the most abundant species emitted by vehicles and represent 90% to 95% of.the total aldehyde emissions.

Large-aperture potassium dihydrogen phos- phate （KDP） crystals are widely used in the laser path of.inertial conf.nement f.sion （ICf. systems. The most common method of.manuf.cturing half.meter KDP crystals is ultra-precision f.y cutting. When processing KDP crystals by ultra-precision f.y cutting, the dynamic characteristics of.the f.y cutting machine and f.uctuations in the f.y cutting environment are translated into surf.ce errors at dif.erent spatial f.equency bands. These machin- ing errors should be suppressed ef.ectively to guarantee that KDP crystals meet the f.ll-band machining accuracy specif.ed in the evaluation index. In this study, the anisotropic machinability of.KDP crystals and the causes of.typical surf.ce errors in ultra-precision f.y cutting of.the material are investigated. The structures of.the f.y cutting machine and existing processing parameters are optimized to improve the machined surf.ce quality. The f.ndings are theoretically and practically important in the development of.high-energy laser systems in China.

We present a domain decomposition method （DDM） devoted to the iterative solution of.time-harmonic electromagnetic scattering problems, involving large and resonant cavities. This DDM uses the electric f.eld integral equation （Ef.E） f.r the solution of.Maxwell problems in both interior and exterior subdomains, and we propose a simple preconditioner f.r the global method, based on the single layer operator restricted to the f.ctitious interf.ce between the two subdomains.

Myrtama 是以它的词法怪癖在 1970 年代从 Myricaria elegans Royle 说出的一个类。自从它的开始，这个类和它的系统的位置的建立被争论了。它从 Tamaricaceae 的 10 种类的序列被报导，并且由 PAUP 4.0b8 和贝叶斯的推理分析了重建发展史。一个单身者它的树分别地从最大的吝啬和 MrBayes 分析被产生。分子的数据集合作为一个姐妹组作为 monophyletic 类，和 Myrtama 为 Tamarix 和 Myricaria 显示出强壮的支持到类 Myricaria。基于词法差别，一棵单个词法树也被产生，在哪个二个主要的系存在但是 Myrtama 是到 Tamarix，而非 Myricaria 的一个姐妹组。从 DNA 序列和 Myicaria elegans 应该被放进既不 Myricaria 也不 Tamarix，但是放在它的自己的 monotypic 类的词法人物支持的证据。
