Pre—Separation Axioms in Fuzzifying Topology

1　 IntroductionYing[5,6 ] introduced and elementally developed so called fuzzifying topology with the semanticmethod of continuous valued L ogic.Shen[7] introduced and studied T0 -,T1-,T2 (Hausdorff) -,T3(regularity) -,T4 (normality) -separation axioms in fuzzifying topology.In [3 ]the concepts of thefamily of fuzzifying pre-open sets,fuzzifying pre-neighbourhood structure of a point and fuzzifyingpre-closure are introduced and studied.It is worth to mention that pre-separation axioms are …     

Second Order Nonlinear Evolution Inclusions Ⅰ： Existence and Relaxation Results

This is the first part of a work on second order nonlinear, nonmonotone evolution inclusions defined in the framework of an evolution triple of spaces and with a multivalued nonlinearity depending on both x（t） and x（t）. In this first part we prove existence and relaxation theorems. We consider the case of an usc, convex valued nonlinearity and we show that for this problem the solution set is nonempty and compact in C^1 （T, H）. Also we examine the Isc, nonconvex case and again we prove the existence of solutions. In addition we establish the existence of extremal solutions and by strengthening our hypotheses, we show that the extremal solutions are dense in C^1 （T, H） to the solutions of the original convex problem （strong relaxation）. An example of a nonlinear hyperbolic optimal control problem is also discussed.     

Calculation of the Specific Heats for the Ⅱ—Ⅲ and Ⅱ—Ⅳ Phase transitions in NH4I

This study gives our calculation for the specific heats CVI due to an Ising model using the observed Cp data for the Ⅱ-Ⅲ and Ⅱ-VI phase transitions in NH4I.By fitting to the CP data we determine the values of the critical exponent for the pressure of 0.14GPa(Ⅱ-Ⅲ phase transition)and for the pressures of 0.75,1.35and 1.97 GPa (II-IV phase transition)in NH4I.Our exponent values values are close to the predicted values of the specific heat in a three-dimensional Ising model.Our calculated CVI are in good agreement with the experimental CP for NH4I in most cases.

Numerical Calculation and Analysis of Track Etching Process

Heavy ion irradiated polymers can be chemically etched to form track membrane with pores in the micro and sub-micro ranges. It has been reported that pore growth during etching can be related to track structures. A latent track has a track core inside and a track halo surrounding the track core. By single track etching it is observed that etching in the track core is much faster than in the track halo where the etching rate is even lower tlian that of bulk material. For multi-track etching, no such stages can be seen by the conductance measurements.     

Molecular cloning and expression of interleukin Ibeta (IL-1β) from red seabream (Pagrus major)

The interleukin 1β (IL-1β) cDNA was cloned from the red seabream (Pagrus major) by homology cloning strategy. A cDNA fragment was amplified by PCR using two degenerated primers, which were designed according to the conserved regions of other known IL-1β sequences, and elongated by 3' ends and 5' ends RACE PCR to get the full length coding sequence of red seabream IL-1β (RS IL-1β). The sequence contained 1252 nucleotides that included a 5' untranslated region (UTR) of 84bp, a 3' UTR of 410 bp and an open reading frame (ORF) of 759 nucleotides which could be translated into a putative peptide of 253 amino acids with molecular weight of 28.6 kD and putative isoelectric point pI of 5.29. The deduced peptide contained two potential N-glycosylation sites and an identifiable IL1 family signature, but lacked the signal peptide and the clear ICE cut site, which were common in other nonmammalian IL-1β genes. The RS IL-1β had the highest homology with piscine IL-1β according to phylogenetic tree analysis.     

Kua的Human压制性打法分析

在《魔兽争霸3》中,Human一直是以防御见长的种族。Footman抵挡穿刺攻击的Defense技能,Paladin的防御光环和Priest的Inner Fire魔法都是用以加强部队防御力量的。而且Human是《魔兽争霸3》中综合移动速度最慢的种族。不但只有Knight具有比较快的移动速度,而且没有任何加速的光环和魔法加以辅助。基于Human的这种特点,以     

EXISTENCE AND UNIQUENESS OF THE SOLUTION FOR NONLINEAR THIRD-ORDER ROBIN BOUNDARY VALUE PROBLEM WITH A TURNING POINT

The paper aims to obtain existence and uniqueness of the solution as well as asymptotic estimate of the solution for singularly perturbed nonlinear third- order Robin boundary value problem with a turning point.In order to achieve this aim,existence and uniqueness of the solution for third-order nonlinear Robin boundary value problem is derived first based on the upper and lower solutions method under relatively weaker conditions.In this manner,the goal of this paper is gained by applying the existence and uniqueness results mentioned above.     

CO、H_2及HO_2在Co/SiO_2催化剂上吸附的原位红外光谱

用原位IR研究了CO在Co/SiO_2催化剂上的吸附,并考察了吸附的CO与H_2、H_2O的相互作用。CO在Co/SiO_2上的吸附显示出四种不同的吸收峰。2002、2027cm~(-1)归属于端基CO吸附;2120cm~(-1)归属于CO在钴离于上的吸附;1870cm~(-1)为CO的桥式吸附;1720cm~(-1)则为多中心吸附。当温度高于370K时,吸附的CO会完全脱附。H_2与吸附的CO相互作用可削弱CO吸收峰的强度,并逐步在低波数(1980cm~(-1))处产生一个小肩。水与吸附的CO相互作用产生一种甲酸基物种(1585、1390cm~(-1))。该物种被认为是Kòlbel-Engelhardt反应的中间体。
