The effect of tramp elements in the steel was intensively studied. It was found that the solubility of tramp elements decreased as the temperature decreased under normal cooling conditions. The tramp elements （Cu, Pb, and Sn） diffused toward the grain boundaries, and intermetallic compounds or rich phases which have low melting points were formed, causing reduction in ductility and failure during the bending test. Rebars with Cu content which were left to air cooling after the last step showed drop in elongation, up to 32 %. On contrast, the samples with high per- centage of tramp elements （Cu, Pb, and Sn） in the billet, which were rolled and subjected to Tempcore process, did not show drop in elongation or failure in bending test （especially for rebar with diameter less than 32 mm）; however, copper must be less than 0.35 mass% to prevent the precipitation of Cu-rich zones of critical size in 32 mm. When quench- ing was applied, the tramp elements remained in the interstitial supersaturated solid solution positions inside the grains and would not have the chance to diffuse and form precipitates, hindering the copper precipitates from reac- hing the critical size necessary for impairing the properties. This would hinder the occurrence of the harmful effect of the tramp elements on the elongation or the hot shortness after rolling.

Objective:To investigate the prophylactic efficacy of date palm fruit extract against doxorubicin-induced hepatotoxicity in Wistar albino ***:The rats were equally and randomly assigned to 6 groups:group 1(untreated control),group 2 and 3 given daily oral administration of prophylactic aqueous extract of date palm fruit at 0.75 and 1.5 mg/kg body weight,respectively,and group 4,5 and 6 intraperitoneally injected with doxorubicin at 15 mg/kg on day *** in group 5 and 6 received daily oral administration of aqueous extract of date palm fruit at 0.75 and 1.5 mg/kg body weight,respectively,for 30 *** phytochemicals identified by GC-MS analysis were analyzed using in silico *** enzymes,liver enzymatic,biochemical parameters and histopathological analysis were determined to evaluate hepatoprotective activity of date ***:Aqueous extract of date palm fruit significantly mitigated doxorubicin-induced changes in activities of liver enzymes,reduced reactive oxygen species levels,and suppressed lipid peroxidation and DNA ***,aqueous extract of date palm fruit reduced doxorubicin-induced hepatic *** docking studies showed that most compounds of aqueous extract of date palm fruit identified via GC-MS had good interaction with proteins of human pregnane X receptor,oxygenase-1,and ***:The aqueous extract of date palm fruit mitigates doxorubicin-mediated DNA damage and hepatotoxicity,and restores normal liver function and may be a promising agent against the deleterious effects of doxorubicin.

村庄规划是实施乡村振兴战略的重要前提,是明确村庄未来发展定位与总体目标的依据。本文通过三都县高硐村平冲寨村庄规划编制和建设为例,浅谈对乡村振兴的启示。一、高硐村平冲寨概况高硐村平冲寨位于三都水族自治县,是一个以水族、苗族共生的特色民族村寨,民族风情浓郁、民族节日众多、民族文化底蕴深厚,有水族文字、鼓舞、芦笙制作、跳月、蜡染等非遗文化;村庄整体格局依山而建,建筑沿主要道路两侧分布,传统民居建筑特征较明显;村庄资源禀赋独特,山水林田相互依存,森林覆盖率超72%;山高坡陡,耕地面积数量少,土地细碎化且不成规模,是典型的喀斯特地貌。
