雄伟壮丽称钟山龙蟠气势磅礴称石城虎踞山势险峻称蜿蜒如龙紫金山以久远历史遍布古迹中山陵承赋着盛名

紫金山位于南京市东郊,古称金陵山。主峰高度低于500米,按照地理学概念应该属于丘陵。因此紫金山又被称作“紫金丘”。战国时楚国在此建金陵邑,即由此山得名。汉代称钟山。拔地而起,形似盘曲的巨龙,称为“钟阜龙盘”。汉末有秣陵尉蒋子文逐盗,死于此。三国吴孙权为此立庙于钟山,改称蒋山。因山坡出露紫色页岩,在阳光照射下闪耀金色光芒,东晋时改称紫金山。     

“五个创新”打造阳光土地市场

气候对人体健康的影响

(1)气候对人的健康和情绪有不可忽视的影响:我们知道气候对某些疾病是有影响的,如关节炎、心脏病。气候也会使人心情烦躁。因此,人们应该掌握这些规律,发挥主观能动性,在心情烦躁时注意克制,有病的人要注意防护。     

由从前采矿活动引起场地污染的放射性评价——德国一般处置方法

在德国东部的某些地区，由从前铀生产和其他矿石开采与处理留下的低放射性废物已被认为是造成环境污染和放射性照射的来源。为了确定合理的治理措施，需要对这些采矿废物及其影响进行详细的调查和适当的放射性证评价。鉴于大量广泛分布的废物，采取了多阶段充分调查的治理措施以尽可能早地排除无关污染源和确定被认为是对环境污染和放射性照射有关的污染源。通过前两个阶段的调查（包括已注册的与采矿有关的可疑地区的查明和已注册包

White spot syndrome virus inactivation study by using gamma irradiation

The present study was conducted to investigate the effect of gamma irradiation on white spot syndrome virus(WSSV). White spot syndrome virus is a pathogen of major economic importance in cultured penaeid shrimp industries. White spot disease can cause mortalities reaching 100% within 3–10 days of gross signs appearing. During the period of culture, immunostimulant agents and vaccines may provide potential methods to protect shrimps from opportunistic and pathogenic microrganisms. In this study, firstly, WSSV was isolated from infected shrimp and then multiplied in crayfish. WSSV was purified from the infected crayfish haemolymph by sucrose gradient and confirmed by transmission electron microscopy. In vivo virus titration was performed in shrimp, Penaeus semisulcatus. The LD50 of live virus stock was calculated 10 5.4 /mL. Shrimp post-larvae(1–2 g) were treated with gamma-irradiated(different doses) WSSV(10 0 to 10-4 dilutions) for a period of 10 days. The dose/survival curve for irradiated and un-irradiated WSSV was drawn; the optimum dose range for inactivation of WSSV and unaltered antigenicity was obtained 14–15 kGy. This preliminary information suggests that shrimp appear to benefit from treatment with gammairradiated WSSV especially at 14–15 KGy.
