The GDSS Framework of Organization-Oriented Dynamic Alliance Based on Multi-Agent

The important strategy decision making system, one of the difficult problems of the research of Group Decision Support System, is an open complex huge system, which is almost non structure and hard to construct. In order to organize and take advantage of decision making departments more effectively, this paper presents the thought of combining Multi Agent System with Dynamical Alliance and set up the GDSS Framework of Organization Oriented Dynamic Alliance based on Multi Agent after analyzing the characteristics of MAS and Dynamical Alliance. Different departments can be organized more effectively on the three layer system structure composed of the strategy layer, the tactics layer and the operation layer. The decision making layer of each department is composed of the integrate decision making subsystem, which means that the decision making layer of each department can be used solely or be a part of Dynamic Alliance to make the important strategy decision and the system gets more flexible.     

A Integrate-Reset-Controlled Single Phase Power Factor Correction with High Efficiency

A novel single phase boost type power factor correction circuit is introduced .The converter's efficiency is greatly improved by improving on the traditional boost type power factor correction circuit. Integrate Reset Control circuit is adopted to realize unity power factor. The Integrate Reset Control high efficiency single phase boost type power factor corrector has these characteristics as follows: It's constant frequency operation, which is of advantage of the design of filter. The control circuit is very simple and no need for multiplier. The result is quiet perfect, the input current follows the input voltage very well. The efficiency is very high. The result of simulation and experiment proves the correction of theory analysis.

新疆喀什市克孜勒河与吐曼河浮游植物群落结构研究

为调查新疆喀什市境内克孜勒河和吐曼河水体中浮游植物群落结构,在该2条河流喀什境内的流域上分别设置了5个采样点,并对每个采样点采集到的水样进行了浮游植物物种鉴定及水体中浮游植物叶绿素a质量浓度的测定.实验结果表明:1克孜勒河和吐曼河喀什段流域水体中,硅藻藻类物种数最多,其次是绿藻和蓝藻.2本次调查中,吐曼河各采样点的水体中浮游植物叶绿素a质量浓度显著高于克孜勒河中叶绿素a质量浓度,这说明吐曼河水体中藻类生物量大于克孜勒河中的藻类生物量,其原因很有可能是吐曼河已经开始受到污染,但其污染程度还需要进一步的调查及检测.若不及时对吐曼河流域加以保护与治理,很有可能影响其浮游植物的多样性,同时水体质量也会恶化.     

水稻穗期应用禾枯灵控病防衰的研究

近年来，缙云县杂交中、晚稻穗期纹枯病、叶尖枯病、鞘腐病、叶黑肿病、紫秆病、稻粒黑粉病多种真菌性病害相继混合发生，造成水稻茎叶早衰，导致结实率和千粒重下降，对水稻产量影响较大，成为严重的穗期早衰综合症，是水稻高产稳产的一大障碍。为此，作者于2003年开展40％禾枯灵(三唑酮多菌灵)防治水稻穗期病害的试验研究，现将主要结果报道如下：     

Prevalence of Salmonella and Yersinia in free-living pied flycatchers (Ficedula hypoleuca) in central Spain

Salmonella and Yersinia are important enteropathogens in poultry and can affect birds of all ages, including embryos. These food-borne zoonotic enteropathogens are of great economic and medical concern worldwide and are intensely studied in poultry. Information regarding the prevalence of these bacteria in wild birds is scarce and biased toward avian species ecologically linked to humans, which have often been incriminated as both reservoirs and disseminators of these enteropathogens. The prevalence of Salmonella and Yersinia recovered from both the feces and eggs in a population of female pied flycatchers (Ficedula hypoleuca) breeding in nest-boxes in central Spain was evaluated. Salmonella arizonae was recovered from the feces of one female but was not recovered from eggs. Yersinia was not detected in either the feces or eggs. These results may suggest that Salmonella and Yersinia may be uncommon in this population studied and may indicate that these birds are unlikely reservoirs of Salmonella and Yersinia.

Computer-based gait analysis of dogs: Evaluation of kinetic and kinematic parameters after cemented and cementless total hip replacement

To date it is unclear whether cementless total hip replacement (THR) in dogs is of clinical advantage in comparison to cemented THR with regard to lameness improvement. Thus the aim of this study was to compare objectively the development of the gait pattern after cemented and cementless THR in dogs. For this purpose, 18 adult dogs with hip dysplasia underwent computer-based gait analysis on an instrumented treadmill prior to unilateral THR and then again ten days, four weeks and four months after surgery. Analysed kinetic parameters were symmetry indices (SI) of vertical ground reaction forces (GRF), which included peak vertical forces (PFz), mean vertical forces (MFz), vertical impulse (IFz), and vertical ground reaction forces of the arthroplasty limbs only. Analysed kinematic parameters were range-of-motion and the flexion and extension angles of hip, stifle and hock joints. The symmetry indice for PVF, MFz and IFz decreased to a value less than six in both THR groups four months after surgery, which is defined as not lame. Improvement in lameness of the arthroplasty limbs during the examination period of four months was not significantly different between the cemented and cementless groups. The results suggest that within a short-term observation period of four months after surgery, neither cementless nor cemented THR have a greater advantage with regard to lameness improvement. Additional studies with larger pools of subjects and longer time periods for follow-up examinations are necessary to verify these findings.
