本试验研究了不同抗应激添加剂对断奶仔猪的影响，试验分四个处理，每个处理做两次重复，其中Ａ处理组为对照组，Ｂ处理组是在Ａ处理组基础日粮上添加电解质及维生素。Ｃ处理组是在Ｂ处理组的基础上添加丝兰属植物提取物（Ｙｕｃｃａｓｏｌｉｄｓ），Ｄ处理组是在Ｂ处理组基础上添加中草药添加剂。试验结果表明，在２１日龄平均日增重方面，添加丝兰属植物提取物（ＹＵＣＣＡ）处理组最好，与对照组比较差异显著（Ｐ＜０．０５），与添加矿物质及多维处理组比较，差异不显著（Ｐ＞０．０５），与添加中草药处理组比较，差异极显著（Ｐ＜０．０１）；其次是添加电解质及维生素处理组较好，与添加中草药试验组比较，差异极显著（Ｐ＜０．０１），与对照组比较，差异不显著（Ｐ＞０．０５）；添加中草药试验组最差，与对照组比较差异显著（Ｐ＜０．０５）；在抑制仔猪下痢方面，添加中草药试验组最好，对照组最差；在料重比方面，添加ＹＵＣＣＡ试验组较好。综上所述，添加丝兰属植物提取物试验组对断奶仔猪抗应激最好。

工作流异常处理的形式描述

异常处理是工作流执行中要解决的主要问题之一，清楚地描述异常处理的过程是最终得到实现的基础。Petri-net对工作流的描述适合于对过程定义进行正确性验证和评价，但描述各种不同条件下的处理策略却很繁琐，采用了一种直观的描述方法对异常处理过程中的元素，即活动、异常处理策略以及处理措施进行了形式化描述，特别是对不同处理策略下的处理过程进行了描述。结合消息机制，分析了一个异常事件出现时，如何处理一个活动实例产生的中间数据，并对事务处理和异常处理的补偿策略进行了比较。描述方法为编码实现提供了很大的方便。     

工作流管理系统中的一种异常处理

目前，开发和运行企业过程的最好工具是工作流管理系统，对于企业这样复杂的应用系统，出现异常是非常频繁和正常的，但企业要求工作流管理系统不仅在正常情况下发挥作用，而且需要灵活地处理各种异常情况。文章设计了数字银行的电话收费业务的异常处理机制，使用JECA规则描述异常处理，同时采用基于CBR的异常处理机制提高系统的灵活性和柔性，增强系统处理异常的能力。     

Why Does the Negative Impact of Inconsistent Knowledge on Web Navigation Persist?

Farris (2003) discovered that users had greater difficulty finding information on a Web site when their prior knowledge was inconsistent with the Web site's content, relative to when their knowledge was consistent with it. In addition, he found that this difficulty was persistent over trials. To explain this persistence, Farris offered a schema-based account, which instantiated inconsistency in a single manner. These studies tested 2 predictions that were derived from Farris's account. Specifically, Experiment 1 assessed whether schema elaboration would be gradual, whereas Experiment 2 assessed whether task repetition would eliminate the negative impact of inconsistent knowledge. The results associated with navigation efficiency supported the predictions derived from Farris's account. The results associated with the choices made by participants as they navigated the site, however, contradicted the predictions. A new account, based on production-rules rather than schemata, is offered that considers both sets of results, because it instantiates inconsistency in more than 1 manner. This new account has implications for the design and redesign of Web sites.

Between the crystalline and the chaotic

This short feature documents elements of research in advance of a long-term work. Rather than a technical account or retrospective, the aim is to demonstrate by example how research itself is a primary process, illustrated by work carried out at the Institute of Creative Technologies (IOCT) during the last few years. When creative output is appraised only from its visible results, something is lost in the telling; carefully selected public facets rarely convey the depths of the underlying lines of inquiry. The research covered is for a work that generates quantitative data, driving visualisations of human movement, proximity and orientation. The aim is to reveal how these literal data reflect our relationships to one another in social settings. To contextualise the current process, complex systems, dynamic pattern formation and other works are also mentioned. As a personal account, it seemed appropriate to supplement the usual academic passive voice with first-person narrative.

Market Appraisal and Accounting of the Cost of Production Capital

It is determined that the cost of sold goods and services in the market of goods, taken into account by the statistics on the nominal gross domestic product and the price index allows estimating the market value of production capital in the national currency. National accounts also take into account the costs of productive capital and fixed capital stocks, which are valued by their market value. It is shown that when the discounted capital is underestimated as compared to the market value, the money in circulation serves turnover only and does not ensure the reproduction of capital. It is also shown that economic growth and technological progress is possible when the value of the recorded production capital is no less than its market value.     

Observations About the Development of Theoretical Computer Science

This paper gives a personal account of some early developments in automata theory and the initiation of research in computational complexity theory. Although the account is subjective and deals primarily with the research areas of direct interest to the author, It discusses the underlying beliefs and philosophy that guided this research as well as the intellectual environment and the Ideas and contacts that influenced it. An attempt is also made to draw some general conclusions about computer science research and to discuss the nature of theoretical computer science.     

Influence of shear deformation on the design of the stiffest elastic beam

The calculus of elastic beams for maximum stiffness, that can be understood in several diffent manners, has been usually performed in current literature taking into account only bending deformation. In the present paper such calculus has been extended taking into account shear deformation as well and comparing these results with those obtained considering bending deformation only. Finally an estimation of the error made disregarding shear deformation is also obtained. Received November 27, 1998     

Influence of Non-Local Effect on the Scattering Properties of NonSpherical Plasmonic Nanoparticles on a Substrate

Based on the discrete sources method (DSM), a new mathematical model is constructed and implemented making it possible to take into account the nonlocal effect (NE) in problems of light scattering by plasmonic nanoparticles located on a substrate. The effect of allowing the NE on the integral scattering characteristics in the spectral range near plasmon resonance (PR) is investigated. It is shown that taking the NE into account leads to a shift and a significant change in the PR’s amplitude.
