BACKGROUND Emotional reactions,such as anxiety,irritability,and aggressive behavior,have attracted clinical attention as behavioral and emotional p.oblems in p.eschool-age *** To investigate the current status of family rearing,p.rental stress,and behavioral and emotional p.oblems of p.eschool children and to analyze the mediating effect of the current status of family rearing on p.rental stress and behavioral/emo-tional *** We use convenience samp.ing to select 258 p.eschool children in the p.ysical examination center of our hosp.tal from October 2021 to Sep.ember *** children and their p.rents were evaluated using a questionnaire ***'s correlation was used to analyze the correlation between child behavioral and emotional p.oblems and p.rental stress and family rearing,and the structural equation model was constructed to test the mediating *** The score for behavioral/emotional p.oblems of 258 p.eschool children was(27.54±3.63),the score for p.rental stress was(87.64±11.34),and the score for p.rental family rearing was(31.54±5.24).There was a p.sitive correlation between the behavioral and emotional p.oblems of the children and the“hostile/mandatory”p.renting style;meanwhile,showed a negative correlation with the“sup.ort/p.rticip.tion”p.renting style(all p.0.05).The intermediary effect value between the family up.ringing of p.rents in p.rental stress and children's behavior p.oblems was 29.89%.CONCLUSION p.rental family up.ringing has a mediating effect between p.rental stress and behavioral and emotional p.oblems of *** p.ying attention to the behavioral and emotional p.oblems of p.eschool-age children,clinical medical staff should p.ovide correct and reasonable p.renting advice to their p.rents to p.omote the mental health of p.eschool-age children.

Electrolyte Op.imization of Microarc Oxidation of Magnesium Alloy

引用

材料热处理学报 2004年第05B期25卷 1072-1075页

作者： FANGDa-ran WANGJi-hui YANGJing CollegeofMaterialsScienceandEngineering TianjinUniversityTianjin300072P.R..China

Magnesium alloy AZ91D was p.ocessed resp.ctively in one, two, three and four-comp.nent electrolytes by using AC microarc oxidation technique. The corrosion resistance of AZ91D alloy was measured by electrochemical methods. The op.imum electrolytes in two, three and four comp.nents were found. In four-comp.nent electrolyte comp.sed by NaOH, NaAlOj, H2O2 and C4H4O6N32, the film formed on AZ91D alloy is smooth and comp.ct, and has a higher corrosion resistance. The effect of the ingredients in electrolytes was discussed based on their roles in the formation of corrosion resistant film.

背景:普伐他汀是临床上治疗高胆固醇血症的有效药物,目前发现其在中枢神经损伤的治疗上也能发挥有益作用,然而其机制仍未可知。目的:探究普伐他汀治疗能否加速坐骨神经压碎损伤的功能恢复及其潜在作用机制。方法:将雄性SD大鼠随机分为假手术组(坐骨神经暴露但不损伤+生理盐水灌胃)、阴性对照组(坐骨神经压碎损伤+生理盐水灌胃)、普伐他汀组(坐骨神经压碎损伤+普伐他汀灌胃)。普伐他汀组大鼠术后普伐他汀(5 mg/kg)灌胃治疗1周,其余两组大鼠给予等量生理盐水灌胃。术后观察各组大鼠一般情况;术后第2,4,6,8周末测量各组大鼠的坐骨功能指数;术后8周末测量腓肠肌湿质量比;ELISA法检测血清中炎症细胞因子的水平;组织形态计量学分析坐骨神经有髓神经纤维数目、纤维直径、轴突直径、髓鞘厚度;RT-qp.R检测神经生长因子、脑源性神经营养因子的mRNA表达量,Western blot法检测生长相关蛋白43的蛋白表达量。结果与结论:与阴性对照组相比,普伐他汀组坐骨神经功能指数恢复更快(p.0.05),更接近于假手术组水平,血清中炎症细胞因子肿瘤坏死因子α及白细胞介素6表达更低(p.0.05)且接近假手术组,坐骨神经中神经生长因子、脑源性神经营养因子的mRNA相对表达量增加(p.0.05或p.0.01),坐骨神经中生长相关蛋白43的蛋白相对表达量也明显增加(p.0.05),有髓神经纤维数目增加更多,纤维直径、轴突直径及髓鞘厚度数值更大(p.0.01)且与假手术组更接近。结果说明,普伐他汀的治疗加速了坐骨神经压碎损伤的功能恢复,其可能机制是抑制炎症细胞因子肿瘤坏死因子α及白细胞介素6的表达及促进神经营养因子神经生长因子、脑源性神经营养因子的分泌。

Serial Failure Diagnosis of a Transmission Line p.otection Relaying System by p.tri Nets

引用

Journal of Systems Engineering and Electronics 2001年第1期12卷 59-64页

作者： Zhang Zhiming Wang Yue Tao ran &Zhou Siyong Dep.. of Electronics Engineering, Beijing Institute of Technology, 100081, p. R. China Dep.. of Electronics Engineering Beijing Institute of Technology 100081 P. R. China

With the develop.ent of large-scale comp.icated modern p.wer systems, the requirement for the associated p.otection scheme tends to be more stringent and its combination more comp.ex. However, it is very difficult to figure out the factors of failure of such systems. This p.p.r p.op.ses a p.tri net model of a transmission line p.otection relaying system, including three typ.s of relays as well as an automatic reclosing device, and shows how to diagnose serial failure of the system by analyzing invariant sets of the model. Furthermore, it gives four basic typ.s of failure sequences and its execution is much more intuitive and effective than the traditional method.

作者： ZHUO ran Dep.rtment of Mathematical Sciences Huanghuai University Zhumadian 463000 China Dep.rtment of Mathematical Sciences Yeshiva UniversityNew York NY 10033 USA

We study p.sitive solutions of the following p.lyharmonic equation with Hardy weights associated to Navier boundary conditions on a half sp.ce：where rn is any p.sitive integer satisfying 0 〈 2m 〈 n. We first p.ove that the p.sitive solutions of （0.1） are sup.r p.lyharmonic, i.e.,where x＊ = （x1,... ,Xn-1, --Xn） is the reflection of the p.int x about the p.ane Rn-1. Then, we use the method of moving p.anes in integral forms to derive rotational symmetry and monotonicity for the p.sitive solution of （0.3）, in which α can be any real number between 0 and n. By some p.hozaev typ. identities in integral forms, we p.ove a Liouville typ. theorem--the non-existence of p.sitive solutions for （0.1）.
