1EXISTENCE AND STABILITY RESULTS FOR GENERALIZED FRACTIONAL DIFFERENTIAL EQUATIONS显示文摘In this paper,a sufficient conditions to guarantee the existence and stability of solutions for generalized nonlinear fractional differential equations of orderα(1<α<2)are given.The main results are obtained by using Krasnoselskii's fixed point theorem in a weighted Banach space.Two examples are given to demonstrate the validity of the proposed results.A.BEN MAKHLOUF D.BOUCENNA M.A.HAMMAMI 2020Acta Mathematica Scientia2020,40,1:2
2与辣椒抗CMV扭关的数量性状位点(QTL)的鉴定显示文摘在辣椒(Capsicum annuum)种内进行抗CMVQTL分析。从感病品种Maor与抗病品种Perennial杂交获得180个F3。在美国和以色列的三个试验中用两个病毒株系接种。大部分RFLP和AFLP标记被用作构建遗传图谱,区间分析被用作QTL检测。有4个QTL与抗CMV显著相关。检测到了两个标记对CMV抗性的双基因互作,没有检测到单基因效用。3个试验中检测到控制表现型变异(cmv11.1)的QTL,其变异最大百分比为16%~33%,该QTL与双基因互作有关。这个QTL与L位点连锁,并证实该QTL与抗TMV有关。在Perennial上早期非常有趣的观察到抗CMV感TMV的现象。来自于不相关的种群的一个高世代的回交育种株系3990,被选择用来分析对CMV的抗性,标记覆盖整个基因组,检测到来自Perennial的基冈渗入。这些基因渗入的区域中包括4个与抗CMV相关的QTL。在两个基因区域的标记被鉴定与抗CMV的QTL相关,同时也与控制果实重量的QTL相关,另外的育种观察也证实对CMV的抗性来源于Perennial和小果型品种。A.Ben Chaim R.C.Grube M.

8CEA/Saclay的ECR轻离子离子源(英文)显示文摘In the beginning of the 90s,T.Taylor and his collaborators demonstrated ECR sources operating at low frequency(i.e.2.45GHz)are able to produce very intense single charge light ion beams. At CEA/Saclay,the SILHI source developments started in 1995.Since 1997 more than 100mA proton or deuteron beams are routinely produced in pulsed or continuous mode.To comply with ADS reliability constraint,important improvements have been performed to increase the installation reliability.Moreover,to optimize the beam transport in the low energy beam line,the extraction system was carefully designed and space charge compensation studies were undertaken.An important step has been reached in 2005 with the development of a permanent magnet source able to produce a total beam of 109mA at 85kV. A new test bench named BETSI,especially dedicated to permanent magnet source developments,is presently under construction.It will allow analysing positive or negative extracted beams up to 50keV and 100mA. In addition,for several years work has been done to optimize the production of negative hydrogen ion beam with such an ECR source.Recent analysis pushed towards the construction of a new set up based on a multicusp magnetic configuration. After a brief overview of the CEA/Saclay source developments,this article will point out on the recent results and present status.R.Gobin P-Y.Beauvais A.Ben Ismail D.Bogard O.Delferriere D.de Menezes R.Duperrier Y.Gauthier F.Harrault P-A.Leroy O.Tuske D.Uriot 2007Chinese Physics C2007,31,S1:0
9Reducing dietary sodium of dairy cows fed a low-roughages diet affect intake and feed efficiency,but not yield显示文摘Wastewater from dairy farms has become a major environmental and economical concern.Sodium residue in treated and untreated wastewater from dairy farms used for irrigation can lead to soil and groundwater salinization,with the risk of soil degradation.We examined the effect of reducing sodium fed to mid to late lactating cows from 0.61%(high sodium[HS])to 0.45%(low sodium[LS])of dry matter on dry matter intake(DMI),milk and milk-component yields,eating behavior,apparent total track digestibility,feed efficiency,and sodium excretion into the environment.We randomly assigned 28 multiparous high-yielding(>35 kg milk/d)cows to 1 of 2 treatment groups(LS or HS)in a crossover design,with 7 d of adaptation and 28 d of data collection.Reducing sodium in the diet reduced sodium intake from 171 to 123 g/d while lowering sodium excreted in the manure by 22%.Energy corrected milk(ECM)yield(37.4 kg/d)and sodium excretion in the milk(33.7 g/d)were similar for both groups.The DMI of LS cows was lower than that of HS cows(27.3 vs.28 kg/d)and consequently,feed efficiency of the LS cows was higher(1.40 vs.1.35 ECM/DMI).Eating rate,meal and visit frequency,and eating time were similar for both treatments;meal and visit duration were longer for the HS cows,and meal and visit sizes tended to be larger.Digestibility of DM and amylase-treated neutral detergent fiber remained similar.Based on the results of this study,and discussed considerations,we recommend lowering the dietary sodium content for mid to late lactating cows in commercial herds to 0.52%of DM,in order to reduce sodium excretion to the environment via urine.Yehoshav A.Ben Meir Yoav Shaani Daniel Bikel Yuri Portnik Shamai Jacoby Uzi Moallem Joshua Miron Eyal Frank 2023Animal Nutrition2023,,1:0
10混凝土路面砖配合比设计的改进显示文摘建筑业要消耗大量原材料和能源。作为原材料选择方法之一,'可持续性'准则是人们在考虑社会和经济可持续发展需求后提出的。本文所介绍内容,涉及预制混凝土产品在传统原材料配合比不适用情况下,如何找到具有竞争力的替代性原材料。本文所提及方法,是将颗粒堆集'干扰'原理,用于混凝土路面砖的配合比设计中。以阿根廷一家混凝土路面砖工厂实际使用的骨料颗粒级配,作为参照,采用骨料破碎加工过程产生、粒径级配不符合要求的废料,替代部分细骨料生产混凝土路面砖,并对产品性能进行检测。测定采用这种固废骨料所配制砂浆试件的物理性能和力学性能。对配合比进行优化,直到获得具有同等力学性能、少水泥用量的配合比;对骨料破碎产生的细颗粒掺加物百分比,进行控制。用三个参数作为评价混凝土配合比'可持续性能'的指标。通过利废,降低路面砖生产对自然环境的影响;此外,还可获得更加经济的混凝土配合料。J.Agnello L.Fernández Luco A.Benítez 崔玉忠(译) 2017建筑砌块与砌块建筑2017,,1:0
11Unraveling the morphological patterns of a subantarctic eelpout:a geometric morphometric approach显示文摘Phenotypic variation in organisms depends on the genotype and the environmental constraints of the habitat that they exploit.Therefore,for marine species inhabiting contrasting aquatic conditions,it is expected tofind covari-ation between the shape and its spatial distribution.We studied the morphology of the head and cephalic sensory canals of the eelpout Austrolycus depressiceps(4.5–22.5 cm TL)across its latitudinal distribution in South Pacific(45°S–55°S).Geometric morphometric analyses show that the shape varied from individuals with larger snout and an extended suborbital canal to individuals with shorter snouts and frontally compressed suborbital canal.There was size variation across the sampled populations,but that size does not have a clear latitudinal gradient.Only 8%of the shape variation relates to this size variation(allometry),represented by a decrease in the relative size of the eye,and a depression of the posterior margin of the head.There were spatial differences in the shape of the head,but these differences were probably caused by allometric effects.Additionally,2 of the canals of the cephalic lateralis pores and the head shape showed modularity in its development.This study shows that the morphology of marinefish with a shallow distribution varies across distances of hundreds of kilometers(i.e.,phenotypic modulation).Fernanda S.ORREGO Mathias HÜNE Hugo A.BENÍTEZ Mauricio F.LANDAETA 2023Integrative Zoology2023,18,2:0
