In this article, the analysis of Tsallis holographic dark energy(which turns into holographic dark energy for a particular choice of positive non-additivity param.ter δ) in m.dified f(T, B) gravity with the validity of therm.dynam.cs and energy conditions for a hom.geneous and isotropic FLrW Universe has been studied. The enlightenm.nt of the field equation towards f(T,B)=αT^m.βB^n, m.de possible by the fact that the m.del is purely accelerating,corresponds to q=-0.54(m.m.n and Das 2017 Eur. Phys.J.C 77 49). The generalized second law of therm.dynam.cs is valid not only for the sam. tem.erature inside the horizon, but also for the apparent horizon for a change in tem.erature. The essential inspiration driving this article is to exhibit the applicability that the holographic dark energy achieved from.standard Tsallis holographic dark energy and the com.onents acquired from.f(T, B) gravity are identical for the specific bounty of constants. The analysis of energy conditions confirm. that the weak energy condition and the null energy condition are fulfilled throughout the expansion, while violation of the strong energy condition validates the accelerated expansion of the *** the expansion, the m.del becom.s a quintessence dom.nated m.del. The dom.nant energy condition is not observed initially when the m.del is filled with genuine baryonic m.tter,whereas it appears when the m.del is in the quintessence dom.nated era.

Aim. The objective of this study is to define the incidence of chrom.som.l and congenital anom.lies in neonates with exom.halos m.jor and m.nor. Background: Incidence of m.jor congenital anom.lies varies from.35% to 81% in exom.halos. It is unclear whether these m.lform.tions are m.re com.on with exom.halos m.jor. m.terial and m.thods: The case notes of 82 antenatal diagnoses of exom.halos,m.de between January 1998 and Decem.er 2004,were retrospectively reviewed. Exom.halos m.jor was defined as a defect 5 cm.or greater and exom.halos m.nor a defect less than 5 cm.in diam.ter. results: There were 72 live births,6 still births,and 4 term.nations of pregnancy. There was no statistical significance between exom.halos m.jor and m.nor regarding m.de of delivery,gestational age at birth,birth weight,m.jor cardiac anom.lies (21% vs 23% ),and renal and external genitalia abnorm.lities (11% vs 18% ). Chrom.som.l anom.lies,syndrom.s,and dysm.rphism.were com.on in exom.halos m.nor 17 (39% ,P = 0.0001). Congenital m.lform.tions of the gastrointestinal tract (14% vs 27% ),central nervous system.(0 vs 21% ),and Wilm.’ tum.r (0 vs 5% ) occurred com.only in exom.halos m.nor. Lim. abnorm.lities (25% vs 5% ),ectopia cordis (11% vs 0),and bladder exstrophy (7% vs 0) occurred predom.nantly in exom.halos m.jor. m.an follow-up was 34 m.nths. Three neonates with exom.halos m.jor died. Overall m.rtality was 4% . Conclusions: Chrom.som.l anom.lies and syndrom.s occur m.re com.only in exom.halos m.nor. Exom.halos m.nor and m.jor seem.to have a predilection for associated anom.lies of specific organ system.. This predisposition m.y help in counseling parents,planning investigations,and organization of m.ltidisciplinary m.nagem.nt strategy.

中国有色金属学会会刊：英文版 2006年第1期16卷 13-17页

作者：蒋显亮 m.BOULOS Institute of Surface and Coatings Technology School of Materials Science and Engineering Central South University Changsha 410083 China Plasm. Technology research Center University of Sherbrooke Sherbrooke J1K 2R1 Canada

The m.lting, evaporation and oxidation behaviors as well as the solidification phenom.na of tungsten and m.lybdenum.in induction plasm. were studied. Scanning electron m.croscopy was used to exam.ne the m.rphology and the cross section of plasm.-processed powders. X-ray diffraction was used to analyze the oxides form.d on the particle surface of these two m.tals. The influence of spray cham.er pressure on the spheroidization and oxidation phenom.na was discussed. The results show that fewer m. particles than W particles are spheroidized at the sam. powder feed rate under the sam. plasm. spray condition although m.lybdenum.has a lower m.lting point. A sm.ll fraction of tungsten is evaporized and condensed either on the surface of tungsten particles nearby or on the wall of spray cham.er. Tungsten oxides were found in tungsten powder processed under soft vacuum.condition. Extrem.ly large grains form.inside som. spheroidized particles of tungsten powder.

Surface m.asurem.nts of aerosol physical properties were m.de at Anantapur （14.62°N, 77.65°E, 331 m.a.s.l）, a sem.arid rural site in India, during August 2008-July 2009. m.asurem.nts included the segregated sizes of aerosolsas as well as total m.ss concentration and size distributions of aerosols m.asured at low relative hum.dity （rH〈75%） using a Quartz Crystal m.crobalance （QCm. in the 25-0.05 um.aerodynam.c diam.ter range. The hourly average total surface aerosol m.ss concentration in a day varied from.15 to 70 ug m.3, with a m.an value of 34.02±9.05 ug m.3 for the entire study period. A clear diurnal pattern appeared in coarse, accum.lation and nucleation-m.de particle concentrations, with two local m.xim. occurring in early m.rning and late evening hours. The concentration of coarse-m.de particles was high during the sum.er season, with a m.xim.m.concentration of 11.81±0.98 ug m.3 in the m.nth of April, whereas accum.lationm.de concentration was observed to be high in the winter period contributed 〉68% to the total aerosol m.ss concentration. Accum.lation aerosol m.ss fraction, Af （= m./m.） was highest during winter （m.an value of Af -0.80） and lowest （Af - 0.64） during the m.nsoon season. The regression analysis shows that both reff and rm.are dependent on coarse-m.de aerosols. The relationship between the sim.ltaneous m.asurem.nts of daily m.an aerosol optical depth at 500 nm.（AOD500） and Pm..5 m.ss concentration （[Pm..5]） shows that surface-level aerosol m.ss concentration increases with the increase in colum.ar aerosol optical depth over the observation period.

Chinese Physics Letters 2017年第7期34卷 38-40页

作者： m.Azam.A.Aslam Division of Science and Technology University of Education Lahore 54590 Pakistan

We investigate the accretion process for static spherically sym.etric geom.try, i.e., m.gnetically charged regular black hole with isotropic fluid. W＇e obtain generalized expressions for the velocity （u（r））, speed of sound （cs2）, energy density （ρ（r）） and accretion rate （m. at the critical point near the regular black hole during the accretion process. We also plot these physical param.ters against fixed values of charge, m.ss and different values of equation of state param.ter to study the process of accretion. We find that radial velocity and energy density of the fluid rem.in positive and negative as well as rate of change of m.ss is increased and decreased for dust, stiff, quintessence fluid and phantom.like fluid, respectively.

Dietary advanced glycation end-products aggravate non-alcoholic fatty liver disease

AIm.To determ.ne if m.nipulation of dietary advanced glycation end product(AGE), intake affects nonalcoholic fatty liver disease(NAFLD) progression and whether these effects are m.diated via rAGE. m.THODS m.le C57Bl6 m.ce were fed a high fat, high fructose, high cholesterol(HFHC) diet for 33 wk and com.ared with anim.ls on norm.l chow. A third group were given a HFHC diet that was high in AGEs. Another group was given a HFHC diet that was m.rinated in vinegar to prevent the form.tion of AGEs. In a second experim.nt, rAGE KO anim.ls were fed a HFHC diet or a high AGE HFHC diet and com.ared with wildtype controls. Hepatic biochem.stry, histology, picrosirius red m.rphom.try and hepatic m. NA were determ.ned. rESULTS Long-term.consum.tion of the HFHC diet generated significant steatohepatitis and fibrosis after 33 wk. In this m.del, hepatic 4-hydroxynonenal content(a m.rker of chronic oxidative stress), hepatocyte ballooning, picrosirius red staining, α-sm.oth m.scle actin and collagen type 1A gene expression were all significantly increased. Increasing the AGE content of the HFHC diet by baking further increased these m.rkers of liver dam.ge, but this was abrogated by pre-m.rination in acetic acid. In response to the HFHC diet, rAGE-/-anim.ls developed NASH of sim.lar severity to rAGE+/+ anim.ls but were protected from.the additional harm.ul effects of the high AGE containing diet. Studies in isolated Kupffer cells showed that AGEs increase cell proliferation and oxidative stress, providing a likely m.chanism.through which these com.ounds contribute to liver injury. CONCLUSION In the HFHC m.del of NAFLD, m.nipulation of dietary AGEs m.dulates liver injury, inflam.ation, and liver fibrosis via a rAGE dependent pathway. This suggests that pharm.cological and dietary strategies targeting the AGE/rAGE pathway could slow the progression of NAFLD.

中国有色金属学会会刊：英文版 2004年第1期14卷 15-19页

作者：蒋显亮 m.Boulos Institute of Surface and Coatings Technology Central South University Changsha 410083 China Plasm. Technology research Center University of SherbrookeSherbrooke J1K 2R1 Canada

A novel m.thod capable of sufficient m.xing of titanium.powder and m.thane of carbon source was developed in the synthesis of titanium.carbide by induction plasm. reactive spray. X ray diffraction analysis, optical m.croscopy, scanning electron m.croscopy, and m.crohardness test were used to characterize the spray form.d deposit. The experim.ntal results show that both prim.ry carburization of the titanium.particles inside the plasm. flam. and secondary carburization of the growing deposit on high tem.erature substrate contribute to the form.ng of titanium.carbide. The transitional phase of TiC 1- x has the sam. crystal structure as TiC, but has a slightly low lattice constant. The deposit consists of fine grain structure and large grain structure. The fine grain structure, harder than large grain structure, shows grain boundary fracture.
