A two-part questionnaire was designed to elicit information on use of print and electronic resources by agricultural science students in Nigerian universities. 912 respondents from faculties of agriculture in three Nigerian universities completed the questionnaires. The results revealed that agricultural science students most prefer to use textbooks (42.1%) among print materials, while The Essential Electronic Agricultural Library (TEEAL) is the most preferred among electronic resources available in their libraries (52.2%). Major problems faced by the agricultural science students include inadequate access to full Internet connectivity and lack of skills on their part to use available electronic databases properly. The study recommends restructuring library collections by increasing the number of agricultural textbooks and databases to meet the information use and retrieval needs of agricultural science students. Other recommendations include establishing Internet-ready computer centers to complement teaching, learning, and research in the library. 相似文献

High precision lab work is feasible and all students can be inducted into such practices from day one. This is also required
by the more commercially/industrially oriented laboratories, though no compendium of such practices exists. Based on experience
in imparting such instruction and analysis to teaching labs as well as larger laboratories, some immediately relevant ideas
are put together here. While the ideas may appear simple, there is danger in thinking that the underlying statistical theory
is also simple, which is often not the case. But even without the relevant theory, much can be achieved in the lab. 相似文献

河流枯水极值分析与模型预测研究 总被引：1，自引：0，他引：1
以我国西南地区澜沧江流域干支流为例,对其枯水特征与径流补给,径流年内变化及其枯水分布做了概要的分析,同时对其河流枯水进行了模型应用研究。通过枯水最小月流量的试验以及显示的随机性,采用了软次模型,利用了11个测站,27a∽31a不等的序列数据,开展了枯水预测计算,其结果多年负轮长为2.13（a）,即小于最小月流量多年平均值。这表明其枯水出现的历时周期短,因此,在对该河流开发时应予以调控,统筹规划。由上可知,运用轮次算法对河流枯水的极值分析与预测是－经济实用的研究方法。 相似文献
