好样的，萍钢人

自１９９６年以来，我曾五下萍钢。第一次去时，萍钢已资不抵债，处于风雨飘摇之际。１９９８年８月，第二次去萍钢，看到在以涂建民同志为首的新班子领导下，一年巨变，受到极大的震撼；以后每次去，都看到萍钢不断发生新的变化，使我受到深刻的教育。萍钢速度现在，不仅在江西，而且在全国冶金界，一提起“萍钢速度”，无不啧啧称叹。这不仅反映在产量的高速增长上，也体现在主要技术经济指标的大幅度改善上；不仅反映在生产上，更体现在技改项目的建设期和达产达效上。１９９６年萍钢的铁、钢产量分别为３９．８万吨和３５．２万吨，至于…     

透视改制后的萍钢

2003年7月23日,有关各方举行了“萍钢国有产权整体转让”签约仪式,萍钢正式改制为民营企业。改制过程中,“再造一个萍钢”的战略部署也开始实施。现在两年过去了。萍钢的改制再造究竟怎样了?业内外很多人士都很关注。最近笔者再次造访萍钢,看到的是一组组令人赏心悦目的数字,听

“转变观念 眼睛向内 功夫下在自己身上”──萍钢扭亏为盈发展纪实

对于萍钢这样一个重点亏损单位，近3年却以每年5000万元的速度扭亏，1999年实现利润1015万元。国家冶金局副局长单亦和评价说：“创造了罕见的奇迹。”对此，萍钢董事长、总经理涂建民撰文认为，关键是萍乡钢铁有限责任公司（原萍乡钢铁厂）创建于1954年，1957年建成投产，是江西省最早的一家钢铁企业。计划经济时期，萍钢作为江西冶金的原料生产供应基地，长期以来产品结构严重不合理，加上经营管理不善，企业长期亏损。随着我国由计划经济向市场经济转化，国有企业普遍存在的困难在萍钢表现得尤为突出：①企业资产负债重，1997年四季度萍…

Zr对高镁铝合金板材综合性能的影响

铝-镁合金具有良好的耐蚀性、优异的成型性和可焊性,广泛用于军、民用舰船上,但其强度不高。本试验通过在AL-Mg-Mn-Cr合金中加入0.1%～0.2%的Zr后,不仅使合金的强度得到提高,同时Zr还能显著细化晶粒,提高抗剥落腐蚀性,改善压力加工性和焊接性。为高镁铝合金在舰船上使用提供了更加优良的综合性能。     

弹簧钢的合金化研究

Bacteria for the nineties

Staphylococcus aureus and Enterococci have gained prominence as the causes of wound infections during this decade. Methicillin-resistant Staphylococcus aureus (MRSA) became commonplace in the United States during the 1980s. In Canada, infections with MRSA have been increasing in frequency since 1995. MRSA develops resistance by producing an altered penicillin-binding protein, PBP 2a, coded for by the mecA gene. Vancomycin is the usual drug of choice. Recently, strains with intermediate resistance to vancomycin (VISA) have been isolated from patients in Japan and the United States. Interim guidelines for their control have been developed by the Centers for Disease Control. Enterococci have developed a resistance to a variety of antimicrobials during the past three decades, including beta-lactams and aminoglycosides. Recently, strains resistant to vancomycin (VRE) have been found in the United States and Canada. They are particularly difficult to treat, although some success has been achieved with experimental drugs. These microorganisms have the ability to escape control by antimicrobials almost as soon as they are developed. Thus, we must practice good infection control and reserve antimicrobials only for clear cases of infection if we are to prevent or delay the emergence of resistance.     

Pulse radiolysis study of the reactivity of chloramphenicol, diazepam and clonazepam with the electron and the hydroxyl radical

Chloramphenicol (CAP), diazepam (DIAZ) and clonazepam (CLONA) have been irradiated in aqueous and methanolic solutions by pulsed electrons (Febetron 707). Spectra of the species formed by the attack of the solvated electron and of OH radical have been determined. The kinetics of reaction of CAP, DIAZ, and CLONA with the solvated electron have been measured. Reactions of radical-radical recombination have also been studied. All these reactions are limited by the diffusion of the reactive species.     

Neuropeptides in the insect brain: a review

Thirty-seven plants are listed, which are used by traditional healers in the central and southern parts of Somalia. For each species are listed: the botanical name with synonyms, collection number, vernacular name, medicinal use, preparation of remedy and dosage. Results of a literature survey are also reported including medicinal use, substances isolated and pharmacological effects. Three plants which should have been included in Part I of the series have been added and some corrections to that paper have been made. With these additions the series comprises 180 different plant species, distributed in 59 plant families.     

Occupational respiratory allergy in bakery workers: a review of the literature

Baker's asthma has long been recognized as a serious disease among workers in the bakery industry and the number of cases with baker's asthma is steadily increasing. This paper presents a review of the available literature on baker's allergy with a special focus on the allergens involved, the epidemiologic research and issues on exposure assessment, evidence of exposure-response-relationships, and possible prevention strategies. A large number of potential allergens have been identified and are described here. At present little is known about the incidence of baker's allergy. On the other hand, a large number of cross-sectional studies have been performed, showing that sensitization and work-related symptoms are common among bakery workers. Only atopy and exposure level have consistently been reported as determinants of this occupational disease. Age, gender, and smoking habits do not seem to be associated with sensitization or work-related respiratory symptoms. Recently, immunochemical methods have been developed to measure specific allergens in the bakery industry, which have been used to unravel the role of allergen exposure in the development of baker's asthma. Clear exposure-response-relationships have been found. The implications of these recent findings for prevention strategies and standard setting are discussed.     

Sesquiterpenoids of the drimane class from a sponge of the genus Dysidea

Ten sesquiterpenoids, including seven new ones, have been isolated from an undescribed sponge of the genus Dysidea. Compounds 1-8 are sesquiterpenoids of the drimane class, while 9 and 10 are 12-norsesquiterpenoids of the same structural class. The structures of novel compounds have been determined by combined spectroscopic methods. These compounds exhibited moderate antimicrobial and enzyme inhibitory (Na+/K(+)-ATPase and PLA2) activities.
