美国法典化运动的背景确实有其独特性，看上去，一直以来总有些律师在呼吁证据立法。但是就是到最近，也难以积蓄起足以推动成文法典颁布的势头。也许“矛盾”一词最能恰如其分地概括许多律师长久以来对证据立法所持的态度。

对风力发电机来说,机械部分和电网部分的优良动力性能是至关重要的。在电网侧,需要满足故障穿越和低短路功率弱电网连结的要求。本文采用联排电力电子器件,给出了一个磁约束控制(pole-restraining control,PRC)的网侧变换器。和现有的控制方法比较,磁约束控制可消除电力电子变换器内部系统的不稳定性,并能极大的增强动态性能。改进的性能通过一个风力发电机的网侧变换器做了验证。并对磁约束控制的原理作了说明,仿真结果表明了瞬态性能有所提高。

In the context of mosquito control, a plethora of devices have been put on the market. The effectiveness of these devices is not always proven, but some have interesting principles that have the potential to be a good means of mosquito control. Among these interesting devices are the photonic traps. We have carried out nightly captures of mosquitoes on human baits in the presence and absence of the device. These captures were made during the rainy season in the localities of Zogbadjè and Mènontin. The captures were made under the same atmospheric conditions at the same locations at 5-day intervals. These captures were made twice per house, indoors and outdoors, with one blank capture without the device and one capture with the device. The captured mosquitoes were identified and classified by genus and their aggressiveness determined by calculating the biting rate. A total of 845 mosquitoes were captured during these captures with 296 mosquitoes captured indoors without the device and 132 mosquitoes with the device present. This represents a decrease of 55.40% in culicidae density. Furthermore, a significant decrease was observed in aggressiveness, from 49 to 22 bites per man per night (b/m/n) with the use of the device. This decrease is even more important for nocturnal species such as Anopheles spp. whose aggressiveness decreased by 90%. The present study confirms the effectiveness of the “Electron go out mosquito small lamp” in reducing Culicidae density and mosquito aggression even in the presence of chemotactic interference. However, this study was limited in time and focused only on the ability of the device to reduce mosquito numbers and did not assess its epidemiological efficacy. It is therefore important to extend the work to examine the influence of the use of this device on population health and the occurrence of mosquito-borne diseases, particularly malaria.

Despite the presence of bye-laws, solid waste management continues to be an issue in Mbarara municipality with households and businesses continuing to dump solid waste on open plots, low-lying areas, public spaces and rivers, or simply burning it in their backyards. This qualitative study aimed at establishing reasons as to why there was still improper solid waste management in Mbarara municipality and also establishing its constraints. Tools used included semi-structured questionnaires, observation and photographs. Two hundred and ninety-four participants （24 solid waste collectors, eight municipal council members and 262 community members） participated in the study. The study revealed both insufficient budget （87.5%） and insufficient equipment （50%） as the most common policy challenges in implementing proper solid waste management. Solid waste collectors not being comfortable with their salaries （79.2%）, limited sensitization regarding solid waste management （66%） and limited necessary tools （58.3%） as other challenges faced by solid waste management policy makers and implementers and finally, community members having limited awareness about laws governing solid waste management （61.1%）. In conclusion, insufficient budget, insufficient equipment, poor motivation and inadequate sensitization were found to be the major reasons as to why there was still improper solid waste management in Mbarara municipality, western Uganda.

Dwindling supplies of bamboo resources and the increase in the demand for bamboo have led to the need for better propagation techniques. This is the only way to ensure the sustainability of the bamboo resource base and improve livelihoods. Thus, this study was carried out to examine the different growth parameters of culm cuttings of Bambusa vulgaris in propagation beds with a substrate consisting of dark soil, manure (compost) and sand in a ratio of 1:1:1. Data on different growth parameters was collected on a daily basis over a three week period and analyzed using appropriate descriptive and inferential statistics. It was found that the different growth parameters (diameter, height, leaves and sheaths) of culm cuttings of B. vulgaris evolved in like manner in three propagation beds. Descriptive statistics for growth parameters of culm cuttings of B. vulgaris showed little or no differences across three shelter/propagation beds (shelter bed 1, shelter bed 2 and shelter bed 3) with 1.4675 ± 1.6172 cm, 93 ± 112 cm, 22 ± 30 leaves, and 4 ± 6 sheaths being the mean diameter, height, number of leaves and number of sheaths for all three propagation beds, respectively. ANOVA test showed no statistically significant variation (p > 0.05) between growth parameters of culm cuttings of B. vulgaris across the three propagation beds, implying that the different growth parameters were relatively similar. Pearson correlation showed the existence of direct and inverse relationships between the different growth parameters of culm cuttings of bamboo. The existence of these direct and inverse relationships could be attributed to the rapid growth rate of bamboo, the substrate used, and the species of bamboo used (B. vulgaris). The study recommends more large-scale propagation projects of this bamboo species in order to ensure the s

40 Ma B.P."原青藏高原"的提出使得青藏高原的早期隆升历史受到越来越多的关注,但其向东的延伸情况不明。青藏高原东缘若尔盖高原、龙门山冲断带和四川盆地有机地构建了一个完整的原-山-盆体系,成为揭示青藏高原隆升和生长的理想场所,而位于高原内部若尔盖地块的红参1井更为此提供了宝贵素材。基于红参1井的构造恢复和低温热年代学研究结果,结合区域上已有的低温热年代学和古高程数据,提出青藏高原东缘在早新生代印-亚大陆碰撞之前就已形成了高原,称之为若尔盖古高原,并从基底构造属性、构造变形、地壳缩短与增厚、沉积记录等方面对其进行了论证。红参1井钻井剖面构造恢复结果揭示所钻遇7 000余米的三叠系复理石层系实际上有46%的厚度是由构造重复所致,连同广泛发育的晚三叠世埃达克质花岗岩以及利用中性岩浆岩Sr/Y比值估算的地壳厚度,共同表明青藏高原东部松潘-甘孜地区在晚三叠世就已发生了实质性的地壳加厚。红参1井多重低温热年代学[锆石(U-Th)/He,磷灰石裂变径迹和(U-Th)/He]测试结果揭示若尔盖地块分别在白垩纪中期(约120 Ma B.P.和约80 Ma B.P.)经历了2次快速的冷却事件,累计剥蚀厚度达5 km,之后转入极其缓慢的冷却过程,暗示其已进入高原化阶段;而在整个新生代期间处于近乎"零"剥蚀的状态而被动地抬升到现今高度(不同于常见的山脉隆升,地块隆升代表了一定范围的区域整体抬升)。因此,青藏高原东部若尔盖地块最晚在白垩纪末期就已形成高原,即若尔盖古高原,其范围可能包括三叠系复理石层系覆盖的大部分松潘-甘孜地区,并可能向西与羌塘古高原相连,构成羌塘-若尔盖古高原。若尔盖古高原的形成不仅造成四川盆地西缘在白垩纪中期出现了重要的物源转变,更重要的是加剧了青藏高原东缘白垩纪气候干旱化,出现了大量沙漠沉积和膏盐沉积。若尔盖古高原的发现不仅有助于深化对青藏高原隆升和生长过程的理解,也将引发对青藏高原形成机制的重新思考以及对其气候-环境-资源效应的关注。
