Olive Oil Consumption in Greece: A Microeconometric Analysis

In this paper, the factors affecting at-home demand for three types of oils and fats in Greece, with emphasis on olive oil, are investigated using the linear approximation of the Almost Ideal Demand System and family budget survey data. To overcome the econometric problem created with the existence of zero expenditure, a generalization of the two-stage Heckman procedure is employed. In order to investigate the role of self-consumption, two different samples were used. The first includes all households; the second excludes those that acquire olive oil only from own production. According to the results, there are important differences in the first stage of the decision process between the two samples. Unlike the first stage, the second stage of the decision process found no important differences between the results for the two samples.

野生花卉在我国北方园林中的应用研究

在现有的城市绿地系统中,千篇一律的园林植物栽培使园林景观单调,且生态效应差。加强野生花卉在园林中的应用可提高城市园林的自然度。我国有着丰富的野生植物资源,其生态习性、观赏特性各异,在园林中的应用方式也多种多样。应积极开展野生花卉的引种驯化等工作,推广野生花卉在园林造景中的应用。     

植物生长调节物质对矮生一品红不定芽增殖的影响

以几种矮生一品红为材料,研究了植物生长调节剂BA,KT,IAA对不定芽增殖的影响.结果表明,影响一品红芽增殖的主要因素是细胞分裂素,以BA的增殖效果较好.不同品种(自由红、彼德之星、金钱豹、塔巴璐卡)芽增殖所需植物生长调节剂的浓度有所不同,矮生一品红试管苗芽增殖的适宜培养基为MS+BA0.5—2.0mg/L+IAA0.25—0.50mg/L.     

Scheduling Updates of Probabilistic Risk Assessments: The Arkansas Nuclear One-Unit 1 Experience

This paper presents the results of a study that identified how often a probabilistic risk assessment (PRA)should be updated to accommodate the changes that take place at nuclear power plants. Based on a 7-year analysis of design and procedural changes at one plant, we consider 5 years to be the maximum interval for updating PRAs. This conclusion is preliminary because it is based on the review of changes that occurred at a single plant, and it addresses only PRAs that involve a Level 1 analysis (i.e., a PRA including calculation of core damage frequency only). Nevertheless, this conclusion indicates that maintaining a useful PRA requires periodic updating efforts. However, the need for this periodic update stems only partly from the number of changes that can be expected to take place at nuclear power plants–changes that individually have only a moderate to minor impact on the PRA, but whose combined impact is substantial and necessitates a PRA update. Additionally, a comparison of two generations of PRAs performed about 5 years apart indicates that PRAs must be periodically updated to reflect the evolution of PRA methods. The most desirable updating interval depends on these two technical considerations as well as the cost of updating the PRA. (Cost considerations, however, were beyond the scope of this study.)

牛心朴子草抗植物病毒组分的生物活性研究

牛心朴子草地上部分醇浸粗提物（H）对烟草花叶病毒（TMV）有高抑制活性。该草抗植物病毒有效组分是菲并吲哚是西定生物总碱（G），半中枯斑法测定（G）制剂对TMV，马铃薯Y病毒（PVY），和芜菁花叶病毒（TUMV）呈现高活性；用酶联免疫法（Elisa)测定(G）制剂对TUMV的最佳浓度防效，与枯斑法测定结果基本要符。（G）中含量最丰的（1）7－脱甲氧基娃儿藤碱（antofine)是该草活性最高的主组分，它在10^-6g/ml浓度的TMV抑制率达60％。
