Reports of irregularities in research done by Karl Illmensee at the University of Geneva prompted an invesigation by Bar Harbor's Jackson Laboratory into collaborative work on embryo manipulation performed by Illmensee and its own researcher, Peter Hoppe. The committee appointed by Jackson Laboratory found no evidence of fraud, but recommended that Hoppe and Illmensee repeat two experiments, since neither had been replicated by other investigators or by Hoppe working alone.  相似文献

Based on the findings of an international commission of inquiry, the Swiss national science foundation has withdrawn its financial support of Karl Illmensee, a University of Geneva embryologist who was accused last year of manipulating experimental protocols. The National Institutes of Health is still considering whether to resume funding Illmensee's work. Loss of financial support could make it difficult for Illmensee to carry out the international commission's recommendation that he repeat the challenged experiments.  相似文献

On page 1151, researchers describe new insights into how genes arise and fuel evolution. By trolling through sequence data for nine very distinct organisms, they have uncovered evidence that genes are copied far more frequently--and the duplicates are lost from the genome far faster--than researchers had thought. What's more, the work suggests that some duplicate genes play a key role in the evolution of new traits and in speciation.  相似文献

The nation is entering a period when the R & D output must be increased, probably without major increases in resource allocation. Obviously, in this situation, either efficiency or productivity must be increased. Perhaps one of the most wasteful aspects of the national R & D system (and one that received little attention during the golden era of the 15 percent per year expansion) has been the very weak coupling between the university, on the one hand, and industry (or government), on the other. It is a serious error to allege about such coupling that "it has never worked," that the objectives and reward structures of the institutions are such that it cannot work, and so on. The fact is that coupling has never been tried seriously. History shows that the total dollar effort in research that required coupling or that had coupling as its main objective was on the order of $10 million per year (that is, much less than 0.1 percent of the research money spent on U.S. campuses). At the same time, there is little doubt that the experiments which must and will be tried in the immediate future call for innovations in management and changes in the attitude and structure of many universities. In conversations with administrators who have had experience with such programs, I have found strong suggestions of very mixed responses from the universities. In light of these responses, and if effectiveness is a goal, it would be better for those universities that are more wedded to disciplinary research, to single principal-investigator work, not to participate in these new efforts. We need much greater diversity in the styles of university life, and it would be healthy for the academic enterprise if some universities retained a greater degree of detachment from society, while others consciously decided to interact more with it, through the private sector, and made the changes necessary to do so. If initial funding is restricted to those universities that consider university-industry or university-government research a worthy objective and that have a proven track record and a favorable administrative and reward structure, the new programs may well establish a major new pattern of national R & D.  相似文献

The National Academy of Sciences (NAS) and the American Physical Society (APS) both met in Washington in the week after Easter. Beyond the coincidence of time and place it is fair to say that the meetings shared a common mood. The truce in Vietnam is generally regarded as the principal cause of a muting of the voices of protest that have been heard at so many scientific meetings in recent years and finally had disturbed the even tenor of the academy's ways. Particularly at APS there seems to be new interest and energy directed to exploring ways to work within the system.  相似文献

姜瘟病是中国生姜生产上发生较为普遍的病害,是由青枯劳尔氏菌(Ralstoniasolanacearum)引起的。此病原菌寄主范围广,可侵染44个科300多种植物。菌体短杆状,在TZC选择性培养基上培养出现白边较宽和白边较窄的两种菌落。菌系划分为5个生理小种和5个生化型,中国的姜瘟菌主要属生理小种1号,生物型属II、III、IV。此病害是一种较难防治的土传病害,在高温、高湿、雨水多、氮肥过量的情况下发生较为严重。中国植病工作者对此病害作了大量的研究工作,对中国姜瘟病的病原菌、发病规律、及防治等研究进展作一综述。  相似文献

威信蕴含着影响力。一个领导者的威信越高则其发挥的影响力越大。威信具有亲近人、熏陶人、感召人、凝聚人、激励人等的影响力,使人心悦诚服。一个领导者要有效地实现领导目标,仅有权力是不够的,更需要有威信。高校图书馆馆长的领导威信对调动馆员的工作积极性、稳定人才队伍以及培养良好的馆风都有巨大影响力。馆长有无威信,关系到一个图书馆工作的顺利开展、服务质量的优化、管理水平的提高以及未来的发展。  相似文献

Five crop straws(wheat, rice, maize, oil-rape, and cotton) were first steam-exploded for 2 min at 210°C, 2.5 MPa and then pyrolyzed at 500°C for 2 h. Steam explosion(SE) induced 47–95% and 5–16% reduction of hemicellulose and cellulose, respectively, in the crop straws. The biochars derived from SE-treated feedstocks had a lower specific surface area(SSA) and pore volume, compared to those from pristine feedstocks, with one exception that SE enhanced SSA of oil-rape straw biochar by approximately 16 times. After SE, biochars had significant higher anion exchange capacity(AEC)(6.88–11.44 cmol kg~(–1)) and point of zero net charges(PZNC)(pH 3.61–5.32) values. It can thus be speculated that these biochars may have higher potential for anions adsorption. In addition, oil-rape straw might be suitable to SE pretreatment for preparing biochar as a soil amendment and sorbent as well. Further work is required for testing its application in soil.  相似文献

Our work has shown that the apparently simple chlorination of unsaturated materials in nonpolar media is actually rather complex because of the occurrence of competitive reaction pathways, one polar and one radical. Means of recognizing, predicting, and separating the pathways have been developed, and general characteristics of each with respect to relative rates and product distributions have been elucidated. A most intriguing discovery is that of the spontaneous generation of radicals by interaction of certain unsaturates and chlorine; much more work is needed for clarifying the nature of this unexpected reaction.  相似文献
