This work presents an optimal harvesting problem associated with a single-species population governed by Gompertz law in a seasonally fluctuating *** influence of environmental fluctuation is accommodated by choosing the coefficients in the differential equation to be periodic functions with the same period and restriction on the harvesting effort is accommodated by considering binding constraints on the control ***,a linear optimal control problem has been considered where the state dynamics is governed by Gompertz equation and the control variable is subject to the binding *** the help of maximum principle and the concept of blocked intervals,an optimal periodic solution has been obtained which is followed by the construe tion of optimal solution using the theory of most rapid *** results of the study are demonstrated through numerical simulations.

We study the properties of proton rich nuclei reported as proton emitters in the region from I to Bi with Z =53 to 83 and n = 56 to 102 as a crucial application to the existence of exotic nuclei. The effective relativistic meanfield formalism(E-RMF), with nL3, FSUGarnet, G3 and IOPB-I interactions, is adopted for analysis of the ground state properties of proton emitters. Furthermore, in the E-RMF background, the Wentzel-Karmers-Brillouin(WKB)barrier penetration method is used for the calculation of proton emission half-lives. It is found that the calculated halflives are in good agreement with the experimental results for all emitters considered in this study.

Easterly waves are one of the rain-bearing systems of northeast monsoon and produce massive rainfall events over south India. In the present case study, an attempt is made to identify extreme heavy rainfall event over south India on 26th October, 2006 due to the passage of the easterly wave. Satellite images provide an inverted v-shape easterly wave. next, circulation features at different levels clearly indicate the location, movement and speed of the easterly wave. Strong north-easterlies with a magnitude of 9.9 m/s are maintained at the surface. The convergence is mainly occupied between 12°n - 16°n, while the divergence is 5°n - 12°n on 26th October, 2006 at the surface level. On 25th, easterly wave is advected north of trough with a magnitude of 0.2 m/s and increased during the remaining days. There are two divergence cells along 5°n and 16°n before and after the event at 700 hPa level. Thus this study helps to bring out the essential characteristics of the easterly wave during northeast monsoon. The highlight of this study is that the easterly wave creates floods in the absence of tropical cyclones over south India.

目的:观察辛化他汀对原发性高血压(EH)心肌纤维化的影响。方法:将60例EH患者随机分为2组:A组28例,单用贝那普利(10mg/d),B组32例,等量贝那普利加辛化他汀(20mg/d)。应用放射免疫分析技术检测Ⅲ型前胶原末端肽(PⅢP),Ⅳ型前胶原末端肽(PⅣP)及转化生长因子(TGFβ1)含量。采用多普勒超声心动图仪测定左室结构及舒缩功能变化。结果:2组患者治疗6个月后,平均动脉压,PⅢP,PⅣP,TGFβ1及室间隔舒张末期厚度,左室后壁厚度指数均较治疗前下降;2组治疗后二尖瓣血流舒张早期流速(VE)和心房收缩期流速(VA)之比均有上升(P<0.01),而B组上升更明显(P<0.05),左室收缩功能指标治疗前后无明显变化;2组比较PⅢP,PⅣP,TGFβ1下降和左室舒张功能改善以B组更明显(P<0.05或P<0.01)。结论:EH患者在接受血管紧张素转换酶抑制药同时,再联合使用辛化他汀,能明显减轻心肌纤维化程度,改善左室肥厚和舒张功能。
