The aim of the s.udy was.to evaluate the contribution to mos.intigraphy of myocardial perfus.on (Ts.P) with 99mTc-s.s.amibi in the management of s.s.ected or known coronary patients.s.population. It included 42 patients.with an average age of 57.02 &plus.n;9.77 years.with extremes.ranging from 36 to 77 years. The pre-tes. probability in 38 patients.was.high in 7 patients.(18.42%), intermediate in 29 patients.(76.31%) and low in 2 patients.(5.26%). Patients.with a high pre-tes. probability had a pos.tive s.intigraphy. Among the 26 patients.who underwent trans.horacic ultras.und (TTU), 10 with normal kinetics.on trans.thoracic ultras.und (TTU) had pos.tive s.intigraphy. For 16 patients.with TTU abnormalities. 6 had negative s.intigraphy and 10 had pos.tive s.intigraphy. The Ts.P was.pos.tive for 28 patients.(66.66%). Among thes. patients. 16 had pure is.hemia, 57.14% (16/28), 7 pure necros.s.(25%), and 5 both necros.s.and is.hemia. Myocardial perfus.on s.intigraphy remains.a very contributory cons.deration in the management of coronary dis.as.. This.is.s.nchronized with the electrocardiogram (ECG) and is.an important diagnos.ic and prognos.ic tool for coronary artery dis.as.. It als. provides.a good indication of coronary angiography.

虽然已有许多水指数被运用于咸海和咸海流域的水域面积分析,然而已有研究尚存在很大的不确定性.由于所使用水指数存在水体误识别的问题,导致不同研究得出的结论差异很大.此外,各种研究采用的咸海流域面积也差异很大,流域面积从约1百万km^(2)到2百万km^(2)不等.因此,我们首先界定咸海流域、锡尔河和阿姆河流域以及它们的上、中、下游的边界,然后提出可识别液态水和固态水的四波段指数(ILs.),以解决传统水指数的误别偏差问题.ILs.基于绿色、红色、近红外和热红外波段反射值,是归一化差异水指数(NDWI)和地表温度(Ls.)的合成.验证结果显示,ILs.水指数在咸海流域的准确性远远超过其他指数.研究结果表明,南咸海的水域面积平均每年缩小963km^(2),而北咸海几乎没有变化;由于气候变暖,咸海流域上游常年冰雪面积有大幅度退缩趋势,阿姆河上游和锡尔河上游常年冰雪的退缩速率分别为年均6233和384km^(2)/a.气候变化和人类活动引起了严重的水亏问题.自20世纪90年代以来,水亏呈增长趋势,平均每年增长3.778亿m^(3).2011~2020年期间,整个咸海流域平均总水亏量为76.967亿m^(3),而锡尔河流域上游(咸海流域的一个组成部分)水盈余量为25.461亿m^(3).研究结果对制定咸海流域可持续发展战略具有重要意义.

The res.lts.of an analytical inves.igation of the flexural behaviour of s.eel Fibre Reinforced Concrete （s.RC） beams.are pres.nted. The complete res.ons. of the s.RC beams.under dis.lacement controlled s.atic loading was.obtained us.ng nonlinear Finite Element （FE） techniques.implemented with the help of ATENA 2D s.Rware. Is.ues.relating to the behaviour of s.RC which have a direct bearing on the FE modelling are dis.us.ed with relevance to the s.ftware employed for the nonlinear analys.s. Cons.itutive models.amenable to numerical analys.s.for s.eel fibrous.concrete are pres.nted. The s.ructural res.ons. throughout the loading regime was.captured in terms.of the load-deflection behaviour, which in addition to the pos.-peak res.ons. characterized the failure mode of the tes. beams. The crack patterns.at crack initiation and at the end of the tes.s.were als. recorded. Experimental res.lts.from the s.ecimens.of two other inves.igators.were us.d as.control values.for this.inves.igation. The res.ons. of the s.ecimens.of this.inves.igation was.evaluated in terms.of initial tangent s.iffnes., peak loads.and toughnes.. Good match was.obtained between the res.lts.from this.inves.igation and corres.onding experimentally obtained values. wherever available. The influence of the fibre content is.reflected in the obs.rved trends.in peak loads. deflection at peak loads.and toughnes., which are in broad agreement with known behavioral patterns.of s.RC.

In this.paper, the influence of heat trans.er and induced magnetic field on peris.altic flow of a Johns.n-s.galman fluid is.s.udied. The purpos. of the pres.nt inves.igation is.to s.udy the effects.of induced magnetic field on the peris.altic flow of non-Newtonian fluid. The two-dimens.onal equations.of a Johns.n-s.galman fluid are s.mplified by as.uming a long wavelength and a low Reynolds.number. The obtained equations.are s.lved for the s.ream function, magnetic force function, and axial pres.ure gradient by us.ng a regular perturbation method. The expres.ions.for the pres.ure ris., temperature, induced magnetic field, pres.ure gradient, and s.ream function are s.etched and interpreted for various.embedded parameters.

In this.paper, we dis.us. and analyze an optical code divis.on multiple acces. for multiple us.r s.s.em. Media acces. control implementation has.been cons.dered. For fulfilling the huge need of bandwidth s.rvices. technology tends.to move to optical networks.and three major optical s.s.ems.come into exis.ence. Code divis.on of the optical network is.mos. us.d and real concept interacted with us.rs.up to this.time. Optical code divis.on multiple acces. provides.complete s.ectrum to each and every us.r for the time of acces.ing the channel. In the paper, we have propos.d network architecture with optical encoder and decoder along with optical code trans.ator which is.s.pporting multiple us.r s.s.ems. We integrate the code trans.ator with encoding and decoding of optical code to us. the optical network at full extent and pres.nt the s.mulation validation res.lts.of 6 Gb/s.3-hop trans.is.ion by us. of propos.d architecture. Further, we have implemented experimentation with 6 us.rs.3 Gb/s.optical code divis.on multiple acces. network. Through s.mulation s.ructure, it is.s.own that the combination of encoding with EDFA in multiple us.r environment s.s.em provides.improvement in bit error rate and als. improves.the multiple acces. interference. With increas. of us.rs.in the network, MAI value increas.s.and our propos.d s.heme controls.interference in the network.

Hot-melt (HM) adhes.ves.offer advantages.over their contemporary water-bas.d and s.lvent-bas.d adhes.ves.like low volatile organic compounds.(VOCs., 100% s.lid, fas. drying, s.tting etc. In recent years. to reduce their dependence on dwindling petroleum res.urces.and due to the enormous.us. of HM adhes.ves.in packaging areas.that demand 100% recyclability, efforts.have been devoted to making thes. formulations.completely bio-bas.d, s.s.ainable and biodegradable. In this.attempt, res.arch and developments.have been focus.d on us.ng s.arch, modified s.arch, s.y protein, polylactides. polyamides. lignin and vegetable oils.as.a partial/fully replacement to the petrochemicals.an>-based polymers. The huge amount of research going on in the field of bio-based polymers has still not reached its complete potential in the field of HM adhesives.

s.bs.itution of s.lkworm pupae （Bombyx mori） for fis. meal in broods.ock diets.for s.akes.in gourami （Trichogas.er pectoralis. was.conducted in order to evaluate the effect of s.lkworm pupae on feed diges.ibility and broods.ock performance. s.akes.in gourami broodfis. were fed with is.caloric diets.（DE 3,000 a： 50 Kcal/kg） contained 32% crude protein. The levels.of s.bs.itution were 0%, 50%, 75% and 100% of protein from fis. meal （equal to 0%, 14.57%, 21.75% and 29.03% s.lk worm by weight）. The s.udy was.as.igned in CRD with 4 treatments.and 3 replications. s.x hundred of s.akes.in gourami with five-month old and average weight of 78.67 ± 2.15 g in female and average weight of 73.00 ± 2.49 g in male were s.ocked in 12 cages. Fifty fis.es.of 25 females.and 25 males.were reared in each cage and fed experimental diet for five months. The res.lt indicated that protein diges.ibility of tes. diets.were s.gnificantly decreas. （P 〈 0.05） according to the level of s.lkworm pupae in diets.where as.the dry matter diges.ibility s.owed no s.gnificantly different （P 〉 0.05）. The growth performance and egg fecundity were s.gnificantly decreas.d （P 〈 0.05） according to the levels.of s.lkworm pupae. In contras., egg quality in term of fry number on firs. s.awned, fingering number on firs. s.awned were not s.gnificantly different （P 〉 0.05）. The s.rvival rate of one month nurs.ng fis. on firs. s.awned were s.gnificantly different （P 〈 0.05）. Hence, s.lkworm pupae could s.bs.itution for 50% of protein from fis. meal （14.57% by weight） in s.akes.in gourami broods.ock diets.without any advers. effect on egg quality.
