基于Multi-Agent的农业专家系统在Internet上的系统设计

该文充分考虑了农业专家系统中需要不同领域知识进行协作,以及领域知识的分布性、易于更新性、可重用性等特点,同时也考虑对原有的各领域专家系统进行利用,提出一个新的基于Multi－Agent的农业专家系统的实现模式.最后,提出一个在Internet环境下的系统实现方案.     

空间分析技术和图论树算法在农业区划中的应用

地域分异规律是区划研究的理论依据,而进行区划的技术关键是如何根据空间相似性实现其合理分割,该研究以地理信息系统的空间数据采集,分析工具为支撑,利用ＧＩＳ的空间邻接分析与图论的树算法相结合的方法对浙江省龙游县农业分区进行了研究,利用该方法建立的自动分区模,运行效率高,且分区结果与当地实际较为符合。     

农业专家系统在农业高校和京郊农村的发展

农业专家系统是一项在信息技术中结合农业特点发展起来的高新技术。它对于提高广大农业人员的科技文化素质,提升农业科技自主创新能力,实现农业生产的跨越发展具有特别重要的作用。高等农业院校和广大农村又是农业专家和农业知识高度密集的地方,更应该使农业专家系统拥有广阔的用武之地。     

论鄱阳湖生态经济区农业产业化经营背景下农村职业教育的发展

《鄱阳湖生态经济区规划》是2009年12月国务院批准的国家区域性战略规划。《规划》中特别指出,要积极推进农业产业化经营以及大力发展职业技术教育。本文从教育功能的角度,阐述＂农村职业教育发展＂与＂推进鄱阳湖生态经济区农业产业化经营＂二者的相互关系。鄱阳湖生态经济区建设离不开农村职业教育的可持续发展。     

Injuries and the 'poor' worker

It is commonly assumed that occupational injuries are less of a problem in developing countries because there is less industrialization. Spot studies reveal, however, that injuries are a serious problem among miners, agricultural workers, and industrial workers in most countries

Each nation differs greatly in its level of industrialization, laws, working conditions, and range of products. Those with lower per capita incomes and lower levels of industrialization are likely to have more decentralized production which is less likely to be controlled effectively. Workers in developing countries are more likely to be injured; injuries are more likely to be disabling; and rehabilitation services more likely to be unavailable. Workers' transiency makes it more difficult for them to appreciate hazards which operate over long periods. Finally, workers' social status and level of organization in many cases greatly reduces their power to promote change

In this paper, an attempt is made to understand which experiences of the rich industrialized nations are valid for other nations and what new research needs to be done.     

我国农产品物流存在的问题与发展对策

伴随农业经济的快速发展,我国农产品物流规模急剧扩大。在快速增长的过程中,我国农产品物流存在着体制不完善、决策不科学、技术水平低和地域差异大等问题,需要通过制定发展规划、提高技术水平、树立现代物流观念等措施来促进我国农产品物流的发展。

Fecal Coliform Removal within a Marshland Upwelling System Consisting of Scatlake Soils

The marshland upwelling system (MUS) was installed on private camps in the Grand Bay National Estuarine Research Reserve, Moss Point, Mississippi. The system was evaluated for its effectiveness in removing fecal coliforms from settled, raw wastewater. A suite of studies was performed at flow rates of 1.9, 2.8, and 5.5 L/min and an injection frequency of 30 min every 3 h to investigate fecal coliform removal. An additional study was performed at a flow rate of 2.8 L/min and an injection frequency of 15 min every hour. Overall, the MUS consistently maintained fecal concentrations below effluent regulatory standards for shellfish harvesting waters (14 most probable number of colonies per 100 mL). Mean influent concentrations of 55,269±2,218,016 colony forming units (CFU)/100 mL were reduced to effluent counts of 2.7±14.07 CFU/100 mL (observed in the 1.5 m wells). Three- to four-log reductions in influent counts were observed over the initial 1.4 vector?m from the injection well. The overall removal followed a first-order decay relationship with respect to vector distance, resulting in removal rate constants ranging from 5.6 to 6.6/m and predicted surface concentrations approaching 0 CFU/100 mL. The 2.8 L/min for 30 min every 3 h treatment provided the best effluent quality.
