The purpos. of this.inventory model is.to inves.igate the retailer’s.optimal replenis.ment policy under permis.ible delay in payments. In this.paper, we as.ume that the s.pplier would offer the retailer partially permis.ible delay in payments.when the order quantity is.s.aller than a predetermined quantity (W). The mos. inventory s.s.ems.are us.ally formed without cons.dering the effect of deterioration of items.which deteriorate continuous.y lik. fres. fruits. vegetables.etc. Here we cons.der the los. due to deterioration. In real world s.tuation, the demand of s.me items.varies.with change of s.as.ns.and occas.ons. s. it is.more s.gnificant if the los. of deterioration is.time dependent. Cons.dering all thes. facts. this.inventory model has.been developed to mak. more realis.ic and flexible mark.ting policy to the retailer, als. es.ablis. the res.lt by ANOVA analys.s.by treating different model parameters.as.factors.

人们早就认为杂种优势是一种现象,利用它能提高作物产量。利用杂种优势获得经济效益的作物数目确实正在不断增加,早期(1921～1954)利用杂种优势的作物有玉米、甜玉米、茄子、矮生西葫芦、蕃茄、菜黄瓜、洋葱、西瓜、胡椒、甜瓜、腌黄瓜、结球甘兰。近年来(1955～1977)利用杂种优势的作物有粒用高梁、糖甜菜、茎椰菜、菠菜、红甜菜、抱子甘兰、胡萝卜、珍珠粟、椰子、花椰菜、苜蓿、大麦、小麦、水稻、向日葵。今后尚待努力解决的有石刁柏、芹菜、燕麦、黑麦、马铃薯、大豆、食荚菜豆、四季豆、碗豆、莴苣。由于植物杂种优势给人们带来巨大的效益,因此育种家和遗传学家都热衷于研究优势种的现象。主要的现象是株高变高,叶面积增大,生产量增加,干物质累积增多,开花提早和产量提高。现逐一分析这些特征。

We report a comprehens.ve s.udy of electrical trans.ort properties.of s.oichiometric (Mg,Ni)-ferrite in the temperature range 77 ≤ T ≤ 300k. applying magnetic field upto 1T in the frequency range 20 Hz-1 MHz. After ball milling of MgO, NiO and ?-Fe2O3 and annealing at 1473k. a (Mg,Ni)-ferrite phas. is.obtained. The temperature dependency of dc res.s.ivity indicates.the prevalence of a s.mple hopping type charge trans.ort in all the inves.igated s.mples. The activation energy decreas.s.by annealing the s.mples.by 1473k. The dc magnetores.s.ivity of the s.mples.is.pos.tive, which has.been explained by us.ng wave function s.rink.ge model. The frequency dependence of conductivity has.been des.ribed by power law and the frequency exponent ‘s. is.found to be anomalous.temperature dependent for ball milling and annealing s.mples. The real part of the dielectric permittivity at a fixed frequency was.found to follow the power law ?/(f,T) ? Tn. The magnitude of the temperature exponent ‘n’ s.rongly depends.on milling time and als. on annealing temperature. The dielectric permittivity increas.s.with milling and als. with annealing. An analys.s.of the complex impedance by an ideal equivalent circuit indicates.that the grain boundary contribution is.dominating over the grain contribution in conduction proces..

Here we pres.nt a method of QT interval meas.urement for Phys.onet's.online QT Challenge ECG databas. us.ng the combination of wavelet and time plane feature extraction mechanis.s. For this.we mainly combined two previous.work.0}one done us.ng the Daubechies.6 wavelet and one time plane bas.d with modifications.in their algorithms.and inclus.on of two more wavelets.(Daubechies.8 and s.mlet 6). But found that out of thes. three wavelets.Daube-chies.6 and 8 gives.the bes. output and when averaged with the interval of time plane feature extraction method it gives.leas. percentage of error with res.ect to the median reference QT interval as.s.ecified by Phys.onet. Our modified time plane feature extraction s.heme along with the wavelet method together produces.bes. re-s.lts.for automated QT wave meas.rement as.its.regular verification is.important for analyzing cardiac health. For the V2 ches. lead particularly whos. QT wave is.of tremendous.s.gnificance we have tes.ed on 530 recordings.of Phys.onet. This.is.becaus. delay in cardiac repolarization caus.s.ventricular tachyarrhythmias.as.well as.Tors.de de pointes.(TdP). A feature of TdP is.pronounced prolongation of the QT interval in the s.praventricular beat preceding the ar-rhythmia. TdP can degenerate into ventricular fibrillation, leading to s.dden death.

AIM： To evaluate roles.of s.ndecan-1, bcl6 and p53 in diagnos.s.and prognos.ication of immunoproliferative s.all intes.inal dis.as. （IPs.D） and to s.udy profiles.of k.ppa （κ） and lambda （λ） light chains.and IgA heavy chain. METHODs. The s.udy cons.s.ed of 11 cas.s.of IPs.D and s.milar number of controls.which included 11 of normal intes.inal mucos. and 11 of high grade B cell lymphoma of ileum. The parameters.analyzed included clinical profiles. biochemical and other laboratory inves.igations. radiologic and his.ological findings.including immunohis.ochemis.ry. REs.LTs. All IPs.D cas.s.had demons.rable s.rum IgA heavy chain and heavy mucos.l plas.a cell infiltration. According to Galian＇s.his.ological s.aging, there were 4 patients.with s.age A and 7 with s.age B. κ and ;λ light chains.were over-expres.ed in 7 patients. 1 s.age A patient had H pylori-pos.tive active gas.ritis.and eradication of H pylori led to dis.as. remis.ion. s.age A biops.es.had higher expres.ion for s.ndecan-1, while s.age B had higher expres.ion for bcl6 and p53. s.ndecan-1,κ and λ light chains.and IgA heavy chain s.owed invers. relations.ip with bcl6 and p53. All patients.were treated with doxycycline. CHOP regime was.added in 5 patients.who developed frank.lymphoma. Three died of the dis.as. due to extens.ve organ infiltration. CONCLUs.ON： Certain immunomark.rs.lik. s.ndecan-1,κ and λ light chains.and IgA heavy chain could be of much help in identifying early s.age IPs.D. s.age B IPs.D s.owed higher expres.ion for bcl6 and p53 than s.age A IPs.D. bcl6 and p53 expres.ions.correlated with a more advanced dis.as. s.age and aggres.ive tumour behavior.

Back.round. Available therapeutic s.rfactants.are either animal-derived or non-protein-containing s.nthetic products. Animal-derived s.rfactants.contain variable amounts.of s.rfactant apoproteins. whereas.the older-generation s.nthetic products.contain only phos.holipids.and lack.s.rfactant proteins.(s.s.. Both decreas. morbidity and mortality rates.as.ociated with res.iratory dis.res. s.ndrome (RDs. among preterm infants. compared with placebo. However, exces. mortality rates.have been obs.rved with non-protein-containing s.nthetic s.rfactants. compared with the animal-derived products. Evidence s.gges.s.that s.nthetic s.rfactants.cons.s.ing s.lely of phos.holipids.can be improved with the addition of peptides.that are functional analogs.of s.s. Lucinactant is.a new s.nthetic peptide-containing s.rfactant that contains.s.napultide, a novel, 21-amino acid peptide (leucine and lys.ne repeating units. k.4 peptide) des.gned to mimic human s.-B. It is.completely devoid of animal-derived components. Objective. We hypothes.zed that the outcomes.for premature infants.treated with lucinactant and poractant alfa would be s.milar. Therefore, we compared lucinactant (s.rfaxin; Dis.overy Laboratories. Doyles.own, PA) with porcine-derived, poractant alfa (Curos.rf;Chies.

Municipal was.e is.one of the mos. hazardous.components.of developing countries. However, enzymes.do provide an eco-friendly s.lution in this.cas.. Amylas. is.an important enzyme in food, textile and pharmaceutical indus.ry and can be us.d for bioconvers.on of was.e. From the municipal s.lid was.e we have is.lated an amylas. producing bacteria that can grow in the irritant municipal was.e and help in their bio convers.tion. The bacteria were identified as.Cronobacter s.k.zak.i Jor52 (C2). The optimized media for maximum amylas. production after 24 h of incubation, contains.2% s.arch, 0.6% peptone, 0.01% CaCl2, 0.05% k.l, 0.05% Mgs.4 and 0.05% k.HPO4. The crude enzyme activity and s.ability s.udy revealed that the amylas. is.s.able within the pH 6 - 8 and temperature 30°C - 40°C and give maximum activity at 37°C at pH-8.
