建设项目环境影响评价的局限性问题

建设项目环境影响评价主要指项目实施后可能带来的负面环境影响预测、分析与评估,进而提出预防不良环境影响的有效措施,实现跟踪监测。但是目前我国建设项目环境影响仍具有一定局限性,只有充分认识到存在的问题,积极改进,才能发挥评价的真正作用。     

汽车侧面碰撞中乘员约束系统的可靠性优化

在汽车侧面碰撞中，约束系统对降低乘员的伤害起到非常重要的作用.本文采用MADYMO仿真分析软件，建立某车型侧面碰撞的约束系统仿真模型；考虑了髋部推动块的压溃力、气囊起爆时间、气体质量流量和气袋排气孔面积对乘员损伤的影响，建立了乘员损伤指标的响应面模型；基于蒙特卡罗随机模拟，进行了侧面碰撞乘员约束系统的可靠性优化.结果表明，优化后的约束系统设计方案满足可靠性目标要求.

Epidemiology of cashew anthracnose (Colletotrichum gloeosporioides Penz.) in Mozambique

Anthracnose of cashew (Anacardium occidentale) was studies on various genotypes and locations in Mozambique. Colletotrichum gloeosporioides was identified as the anthracnose causal agent using polymerase chain reaction. The relationships between incidence and severity of anthracnose on cashew genotypes were statistically analyzed by regression. Anthracnose leaf incidence, which is practically easy to evaluate, was consistently associated with leaf severity, and their relationships can be estimated using the restricted exponential function across locations, crop seasons, genotype and fungicide trials. Pooled data enabled estimation of initial incidence of 1.43% with percentage variance accounting for 83.2 and standard error of 8.3. By computing incidence data into the summary equation, 24 changes of 0, 1, 5, 10 and 40%, resulted in changes of severity estimates of 0.01, 0.05, 0.10, 0.50 and 1.00%, respectively. The maximum disease incidence was estimated as 80% when the severity reached only 5%. Increase in severity was observed afterward, approached a maximum of 25% when leaf detachment is observed. The use of incidence data for epidemic comparisons, genotype and fungicide evaluation in cashew orchards is recommended. Anthracnose incidence on leaves however, could not predict incidence on nuts.     

太原经济技术开发区用地效益评价

通过对太原经济技术开发区的实际调查和对2002—2011年10 a间的相关统计及国家商务部历年发布的国家级经济技术开发区发展报告的信息进行分析,从开发区土地利用现状、年度建设用地供给、科工贸收入、工业总产值、GDP、税收收入、国内外资金利用等方面,综合评价了太原经济技术开发区的经济效益和用地效益。结果表明,该区独立运行10 a来成绩显著,整体效益逐步提高,在山西所有开发区中经济效益名列前茅,在全省经济技术开发区中每年的综合评价都名列第1;与国内中西部或中部的同类开发区相比,该区经济总量和单位面积产生的效益排名中后;与国内先进经济技术开发区相比,差距较大;该区内部分企业规模大、影响广泛,经济效益和用地效益均好,起到了带头和示范作用,但仍有部分企业规模小、投入水平低、建设周期长、产生效益低,影响了全区整体效益的发挥。建议开发区管委会引导入区企业加大投入,加快建设步伐,及早产生经济效益;尽快实施扩区计划,保证经济快速、健康发展;落实土地供给和退出政策,使有限的土地发挥更大的效益。

Evaluation the effect of subchronic feeding of transgenic cotton line (CKC1) on the faecal microbiota of albino rabbits

Recent studies have demonstrated a strong relationship between the intestinal microbiota and the host health. As such, consumers are increasingly becoming more concerned about the potential effect of certain foods/feeds, particularly of transgenic origin on the gut microbiota. Although the European Food Safety Authority has recommended in their guidelines, to study the effect of transgenic food/feed on host-microbiota, yet, few studies have focused on the evaluation of such effects mainly due to culturing difficulties. Therefore, this study was intended to evaluate the potential adverse effects of transgenic diet consumption on some specific gut microflora (Lactobacillus group, Bifidobacterium genus, Escherichia coli subgroup and Enterococcus genus) of rabbits. A total of forty-eight rabbits were randomly assigned into four groups and fed a diet containing a variable proportion of transgenic cottonseeds at 0, 20, 30 and 40% inclusion level, respectively. Changes in the specific or total faecal bacterial population were monitored at five different experimental stages (i.e. 0, 45, 90, 135 and 180 days) using both the traditional plate count method (TM) and quantitative real-time PCR (qPCR). No significant differences (p > .05) were observed concerning numbers of specific bacteria or total bacteria between the control and experimental groups, though qPCR showed numerically higher values in terms of 16S rRNA gene copies as compared to the values obtained from TM. However, such numerical differences were biologically insignificant (p > .05). Similarly, no significant variations were noticed in the calculated B/E (log₁₀ copies of Bifidobacterium per g faces/log10 copies of E. coli genome per g faeces) ratios in all the groups. All the ratios were in the range of 1.24 to 1.30 throughout the experiment, indicating a good balance of intestinal microflora and greater resistance to intestinal disorders. It is therefore concluded that feeding transgenic cottonseeds could not adversely affect the gut microflora of rabbits during a long-term study.
