Tin sulfide （SnS） thin films were prepared by electrodeposition onto fluorine-doped tin oxide （FTO） glass substrates using an aqueous solution containing SnCl2 and Na2S2O3 at various deposition potentials （L） and bath concentrations. The pH value and temperature of the solution were kept constant. The deposited films were characterized using X-ray diffraction （XRD）, field-emission scanning electron microscopy （FESEM）, photoluminescence （PL）, and ultraviolet-visible （UV-Vis） spectroscopy. The FESEM images demonstrated that changes in the deposition potential （E） and solution concentration led to marked changes in the morphology of the deposited SnS films. Energy-dispersive X-ray analysis （EDXA） results showed that the SrdS atomic ratio strongly depended on both the solution concentration and the deposition potential. To obtain an SrdS atomic ratio approximately equal to l, the optimal Sn2＋/S2O2- 3 molar ratio and E parameter were 1/8 and -1.0 V, respectively. The XRD patterns showed that the synthesized SnS was obviously polycrystalline, with an orthorhombic structure. The effects of the variations of bath concentration and deposition potential on the band-gap energy （Eg） were studied using PL and UV-Vis experiments. The PL spectra of all the SnS films contained two peaks in the visible region and one peak in the infrared （IR） region. The UV-Vis spectra showed that the optical band-gap energy varies from 1.21 to 1.44 eV.

We present an efficient, fast and simple strategy of generating the intermediate carbamoyl chlorides from secondary amines using stoichiometric amounts of bis（trichloromethyl）carbonate （BTC） in solution and solvent-free conditions with excellent yields. The results obtained showed the yield increasing on whether a base was used. Finally, an efficient and rapid synthesis of variety carbamate derivatives was developed by the reaction with a high variety of different alcohols, phenols, diols and this intermediate at room temperature with grinding and in solvent-free conditions under microwave irradiation. The presence of various safe bases is shown to be effective in reducing the reaction times, increasing the yields and easing purification. The present method does not involve any hazardous phosgene.

Electroplating of Ni/Co–pumice multilayer nanocomposite coatings: Effect of current density on crystal texture transformations and corrosion behavior

引用

International Journal of Minerals,Metallurgy and Materials 2019年第10期26卷 1299-1310页

作者： Mehdi Boroujerdnia Hamid Ghayour Ahmad Monshi Reza Ebrahimi-Kahrizsangi Farid jamali-Sheini Advanced Materials Research Center Department of Materials EngineeringNajafabad BranchIslamic Azad UniversityNajafabadIran Advanced Surface Engineering and Nano Materials Research Center Department of PhysicsAhvaz BranchIslamic Azad UniversityAhvazIran

The present paper aims to investigate the influence of the current density in the electroplating process on the microstructure, crystal texture transformations, and corrosion behavior of Ni/Co pumice multilayer nanocomposite coatings. The Ni/Co pumice composite coatings were prepared by deposition of Ni, followed by the simultaneous deposition of pumice nanoparticles (NPs) in a Co matrix via an electroplating process at various current densities. Afterward, the morphology, size, topography, and crystal texture of the obtained samples were investigated. Furthermore, electrochemical methods were used to investigate the corrosion behavior of the produced coatings in a solution of 3.5wt% NaCl. The results indicated that increasing the plating current density changed the mechanism of coating growth from the cell state to the column state, in- creased the coating thickness, roughness, and texture coefficient (TC) of the Co (203) plane, and reduced the amount of pumice NPs incorporated into the Ni/Co pumice composite. The electrochemical results also indicated that increasing the current density enhanced the corrosion resistance of the Ni/Co pumice composite.

BACKGROUND: Controversy exists about the correlation between liver ultrasonography and serum parameters for evaluating the severity of liver involvement in non-alcoholic fatty liver disease (NAFLD). This study was designed to determine the association between liver ultrasonography staging in NAFLD and serum parameters correlated with disease severity in previous studies; and set optimal cut-off points for those serum parameters correlated with NAFLD staging at ultrasonography, in order to differentiate ultrasonographic groups (USGs). METHODS: This cross-sectional study evaluated outpatients with evidence of NAFLD in ultrasonography referred to a general hospital. Those with positive viral markers, abnormal serum ceruloplasmin or gamma-globulin concentrations were excluded. A radiologist performed the ultrasonography staging and stratified the patients into mild, moderate, and severe groups. Fasting serum alanine aminotransferase (ALT), aspartate aminotransferase, alkaline phosphatase, triglyceride (TG), high and low density lipoprotein (HDL, LDL), and cholesterol were checked. RESULTS: Two hundred and forty-five patients with a mean age (±standard deviation) of 41.63(±11.46) years were included. There were no significant differences when mean laboratory concentrations were compared between moderate and severe USGs. Therefore, these groups were combined to create revised USGs ('mild' versus 'moderate or severe'). There were associations between the revised USGs, and ALT, TG, HDL levels, and diabetes mellitus [odds ratios=2.81 (95% confidence interval (CI): 1.37-5.76), 2.48 (95% CI: 1.29- 4.78), 0.36 (95% CI: 0.18-0.74), and 5.65 (95% CI: 2.86-11.16)respectively; all P values <0.01]. A cut-off value of 32.5 mg/dL for ALT gave a sensitivity of 70% and a specificity of 62%, for differentiating between the revised USGs. CONCLUSIONS: Serum ALT, TG, and HDL concentrations seem to be associated with the staging by liver ultrasonography in NAFLD. They might be used to predic

Ebola viral disease: a review literature

Asian Pacific Journal of Tropical Biomedicine 2015年第4期5卷 260-267页

Ebola virus is transmitted to people as a result of direct contact with body fluids containing virus of an infected patient. The incubation period usually lasts 5 to 7 d and approximately95% of the patients appear signs within 21 d after exposure. Typical features include fever,profound weakness, diarrhea, abdominal pain, cramping, nausea and vomiting for 3-5days and maybe persisting for up to a week. Laboratory complications including elevated aminotransferase levels, marked lymphocytopenia, and thrombocytopenia may have *** fever occurs in less than half of patients and it takes place most commonly in the gastrointestinal tract. The symptoms progress over the time and patients suffer from dehydration, stupor, confusion, hypotension, multi-organ failure, leading to fulminant shock and eventually death. The most general assays used for antibody detection are direct IgG and IgM ELISAs and IgM capture ELISA. An IgM or rising IgG titer(four-fold) contributes to strong presumptive diagnosis. Currently neither a licensed vaccine nor an approved treatment is available for human use. Passive transfer of serum collected from survivors of Junin virus or Lassa virus, equine IgG product from horses hypervaccinated with Ebola virus, a "cocktail"of humanized-mouse antibodies(ZMapp), recombinant inhibitor of factor VIIa/tissue factor,activated protein C, RNA-polymerase inhibitors and small interfering RNA nano particles are among the therapies in development. Preclinical evaluation is also underway for various vaccine candidates. One is a chimpanzee adenovirus vector vaccine; other vaccines involve replication-defective adenovirus serotype 5 and recombinant vesicular stomatitis virus.

Acute Morphine Administration Reduces Cell-Mediated Immunity and Induces Reactivation of Latent Herpes Simplex Virus Type 1 in BALB/c Mice

Cellular & Molecular Immunology 2009年第2期6卷 111-116页

Acute morphine administration is known to alter the course of herpes simplex virus infection. In this study, the effect of acute morphine administration on the reactivation of latent herpes was investigated in a mouse model. Because of the important role of cytolytic T lymphocyte （CTL） activity in the inhibition of herpes simplex virus type 1 （HSV-1） reactivation, the effect of acute morphine administration on CTL responses was also evaluated. Furthermore, lymphocyte proliferation and IFN-γ production were evaluated for their roles in the induction of the CTL response. The findings showed that acute morphine administration significantly reduced CTL responses, lymphocyte proliferation, and IFN-γ production. Furthermore, acute morphine administration has been shown to reactivate latent HSV-γ. Previous studies have shown that cellular immune responses have important roles in the inhibition of HSV reactivation. These findings suggest that suppression of a portion of the cellular immune response after acute morphine administration may constitute one part of the mechanism that induces HSV reactivation.

CONCURRENT PRODUCTION ENGINEERING SYSTEM FOR BUFFER SIZE AND FLEXIBLE TRANSFER LINE LAYOUT DESIGN

引用

Journal of Systems Science and Systems Engineering 2008年第2期17卷 187-203页

作者： Hidehiko YAMAMOTO Jaber ABU QUDEIRI M.Anouar jamali Intelligent Manufacturing Systems Laboratory Gifu UniversityJapan Department of Industrial Engineering University of Quebec at Trois-Rivers(UQTR)Canada

In this paper we propose a COncurrent Production Engineering System （COPES） for the flexible transfer line （FTL） layout design in a restricted area. COPES first determines the buffer size in front of the bay of each machine tool in the FTL and then initializes a computer aided design （CAD） system to draw the FTL in a restricted area. We develop a set of modules systems which have been integrated into a single framework, in accordance with the practice of concurrent engineering. Concurrent engineering involves the cooperation of these activities. It＇s expected that the developed COPES can improve the cooperation between production engineers＇ and the plant designer. This can be done by enabling the production engineers＇ to make better decision regarding FTL buffer size.
