GLOBAL BEHAVIOR OF POSITIVE SOLUTIONS TO A KIND OF THREE-POINT BOUNDARY VALUE PROBLEMS

引用

Annals of Differential Equations 2009年第4期25卷 473-482页

作者： Shumei Yu, Hongxi Wang (Dept. of Applied Math., Institute of Applied Math., anhui agricultural university, hefei 230036)

In this paper, using the fixed-point index theorems and the cone theory we study the structure of the positive solutions to a kind of second-order three-point boundary value problems. We obtain the result which guarantee that the positive solution set of the three-point boundary value problem has a continuum, which means that there exists a nonempty, closed and connected subset.

The present study was aimed to investigate the developmental patterns of leptin mRNA expression in dorsal subcutaneous adipose tissue and Ob-Rb mRNA expression in hy[(-)-23.8( )]pothalamus in pigs of different breeds and sexes. [(Erhualian gilts and boars and Large White)0( )]boars were sampled at birth, 3, 20, 30, 4., 90, 120 and 180 days of age, respectively. Serum concentration of leptin was measured with RIA and single tube semi-quantitative RT-PCR was applied to determine the relative abundances of mRNA expression using 18S rRNA as an internal standard. The results showed that leptin mRNA expression in adipose tissue increased with age and displayed both sex and breed differences. In Erhualian pigs, females expressed higher leptin mRNA compared with males, and Erhualian boars showed higher abundance of leptin mRNA than Large White boars (P 23.8( )][(creased till weaning. )0(After weaning, Ob)0(-)]Rb gene expression decreased gradually with age but rose gradually again from 120 to 180 days of age in Erhualian pigs. [(The expression of Ob)0(-)(Rb)( )]mRNA was higher in Large White pigs than that in Erhualian pigs (P< 0.01). The results suggest that the serum leptin level and leptin gene expression in adipose tissue highly correlate with [(adiposity.)0( )]

太湖主要鱼类的食物组成

根据2004.9-12月和2005年4.的调查,研究了太湖8种鱼的食物组成。结果表明:优势种鲚主要摄食枝角类、占食物个数比例89.77%±13.69%;太湖新银鱼主要摄食桡足类、占个数比例70.11%±10.57%;鲢、鳙主要摄食微囊藻、占食物体积比例90%以上... 详细信息

根据2004.9-12月和2005年4.的调查,研究了太湖8种鱼的食物组成。结果表明:优势种鲚主要摄食枝角类、占食物个数比例89.77%±13.69%;太湖新银鱼主要摄食桡足类、占个数比例70.11%±10.57%;鲢、鳙主要摄食微囊藻、占食物体积比例90%以上;鲤食物中水生植物约占体积比例70%;鲫主要摄食微囊藻、占体积比例93.99%±3.34.;翘嘴红、蒙古红主要摄食鲚和小型鱼类。分析认为,随着太湖富营养化程度不断加重,以蓝藻为主的浮游植物食性鱼产力在快速增加,但实际渔获量以浮游动物食性鱼类为主。如2003年浮游植物食性鱼产力为10 234.、占总鱼产力37.0%。而2004.实际渔获量中浮游动物食性鱼类占80%~90%,浮游植物食性鱼类渔获量仅3637.7t、占10.9%。因此,太湖现有鱼类群落组成和实际饵料构成是不吻合的。不仅如此,浮游动物食性鱼类数量的快速增加对浮游动物形成了巨大牧食压力,这更利于藻类繁殖。太湖鲫几乎完全以微囊藻为食物,可能对蓝藻暴发有抑制作用,应重新评价其对环境的影响。

通过反射干涉对比显微技术和快速图像分析技术,捕获细胞质膜外光晕变化和细胞周边边缘激发变化的信息,并采用闪烁本征模式分解测定柠檬醛作用于黄曲霉质膜前后各模式（m=0,1,2）所对应的平均平方振幅2m>、剪切弹性μ和弹性弯曲模量Kc,与理论模式光谱相比,研究柠檬醛损伤质膜的物理机制.结果表明,m=1的平动模式主导了光晕波谱,其平均平方振幅呈双指数衰变,该模式几乎与剪切弹性无关,即μ=0;弹性弯曲模量Kc的最小和最大值分别为9.4.×10-18J和5.4.×10-17J,与柠檬醛的浓度成正相关性.揭示该醛对黄曲霉质膜的损伤,除改变膜的选择通透性和电导率外,同时使质膜平动模式的平均平方振幅呈双指数衰变,弹性弯曲模量Kc增加,从而降低膜伸缩的弹性.
