加速设备改造 提高装备水平

工业设备是工厂维持简单再生产的物质技术基础，而企业技术装备水平高低是体现企业由粗放型经营向集约化经营转变的重要标志。装备水平是指在技术进步条件下，技术装备适应生产和技术发展的内在品质，即企业技术装备水平的高低和技术状况的优劣。它能直接反映企业技术进步的程度、生产能力的大小、现代化程度的高低。因此，没有设备的更新改造、装备水平的提高，就没有企业生产规模的扩大、产品质量的提高，也就谈不上企业经济效益的增长。从全省冶金工业第三次工业普查结果可以看出，我省冶金企业主要生产设备的装备水平参差不齐，新厂水平…

Romantic jealousy: Five perspectives and an integrative approach.

Discusses the psychodynamic, systems, behavioral, social psychological, and sociobiological perspectives on romantic jealousy. The psychodynamic approach views jealousy as the result of unresolved childhood experiences and as best treated by individual psychotherapy. The systems approach views jealousy as the result of the dynamic in a particular relationship and as best treated by couple therapy. The behavioral approach views jealousy as a learned response that can be unlearned. The social psychological approach views jealousy as determined by the social environment and as best treated by shifting from a dispositional to a situational attribution. The sociobiological perspective views jealousy as innate and its treatment application involves breaking couples' fallacy of uniqueness regarding jealousy. An integrative approach using contributions of all 5 perspectives is suggested and a case example is provided. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

A shift in types of nutrition and digestion in ontogeny

The article generalises research data from experiments with animals and observations on man. These allow to identify specific features of digestion, as well as of alimentation starting from a zygote stage, which are organised and developed by the organism itself. The following stages were outlined: hystotrophic stage--that of an embryo; hematrophic, which is combined in the foetal stage with the omntrophic and lactrophic after birth. The article discusses the extreme importance of the latter, both in the trophogenic aspect, as well as for determining the future post-natal formation of the organism advanced in the biological, as well as in the socio-economic aspects.     

A possible correlation between the blood leukocyte formula and the use of glucocorticoids as growth promoters in beef cattle

The frequency of lumbar disc hemiation amounts to 5.1% with the male and 3.7% with the female population. Because of the often long-time pain-conditional impairment of the patients as well as the varied therapy-possibilities, the treatment of the ruptured lumbar intervertebral disc represents a special challenge. The indication to the operation for the lumbar disk-herniation results from the malfunctions of the nerve roots, the pains, as well as the temporal course of the symptoms. New and important developments have given the introduction of micro-surgical operation-techniques into the orthopedics. This development has led to it that many orthopedists and neurosurgeons the micro-surgical operation-technique prefers. Important for the micro-surgical lumbar discectomy is the operation-microscope, a good preoperative diagnostics as well as a particular micro-surgical operation-instrument. Through the different enlargement-possibilities of the operation-microscope, all anatomical structures can increase and are done visibly for the surgeon as well as the assistant. Intraoperative injuries of the dura as well as the spinal-nerves are certainly avoided hereby. The micro-surgical discectomie requires no longer time like the conventional operation of the disk. The postoperative stay in the hospital as well as the time of the work-incompetence is reduced. Postoperative inflammations of the disk-area as well as renewed operations are rarer with the microchirurgischen technique. If an operation is necessary, so this should not be out-hesitated too long in order to avoid bed results.     

Overview on Basic Types of Hot Rolling Textures of Steels

The present study gives a review on basic types of crystallographic textures developing during hot rolling of polycrystalline steels. The results are grouped into three fundamental classes of textures. The first group comprises pure Fe, some weakly bonded B2 and DO₃ structured intermetallics, as well as closely related alloys such as ferritic low carbon and microalloyed interstitial free steels. The second group includes highly alloyed corrosion‐resistant ferritic stainless and Fe‐Si transformer steels. Typical examples are steels with about 10 wt.%‐17 wt.% Cr, with about 3 wt.% Si, as well as body centered cubic transition metals such as Ta, Mo, and Nb which do not undergo any phase transformation during hot rolling. The third group comprises stable and instable austenitic stainless steels for instance on the basis of larger amounts of Cr and Ni or on Mn as well as duplex steels. Most L1₂ structured intermetallic alloys can also be assigned to this group. The suggested classification scheme is discussed in terms of different processing parameters, thermodynamics, microstructure, and crystallographic aspects.     

Direct communication on the Internet. Uninet: the university link for Integrate Telematic Services

The importance of Internet as a communication medium is clear due to the amount of information it distributes and the high number of potential recipients it has. The appearance of virtual user communities (CMV) focuses to information classification within subjects of interest for certain groups of people in order to facilitate its search and use. The UniNet project of Integrated Telematic Services for CMV through, as well as other subprojects, the 'propuesta RedUni' encourages the creation of CMV by mean of integration of various computer and Internet resources, such as distribution mailing list, web pages, Internet Relay Chat (IRC), etc. The current state of IRC in such context is presented and the utilities of the known as Scientific-IRC as a professional real time communication tool are discussed.     

Leukemia cutis. Fine needle aspiration findings

OBJECTIVE: To aspirate, for cytologic study, skin nodules from known cases of leukemia during full remission. STUDY DESIGN: The study group consisted of nine leukemia patients in full remission who developed skin nodules on the head, face, chest and upper extremities. RESULTS: The size of the nodules ranged between 1 and 3.5 cm. The nodules were aspirated with 21-gauge needle. Four were diagnosed as acute lymphoblastic leukemia, 1 as chronic lymphocytic leukemia, 1 as acute myeloblastic leukemia, 2 as acute monocytic leukemia and 1 as acute promyelocytic leukemia. Histologic sections were diagnosed as lymphoma-leukemia. The patients developed leukemia again three to four months after excision of the skin nodules. CONCLUSION: Fine needle aspiration cytology is useful in the diagnosis of leukemia cutis.     

Serological titers of equine monocytic ehrlichiosis associated with gastro-intestinal disorders and serological follow-up on two endemic farms

A sulfate-reducing bacterium using trinitrotoluene (TNT) as the sole nitrogen source was isolated with pyruvate and sulfate as the energy sources. The organism was able to reduce TNT to triaminotoluene (TAT) in growing cultures and cell suspensions and to further transform TAT to still unknown products. Pyruvate, H2, or carbon monoxide served as the electron donors for the reduction of TNT. The limiting step in TNT conversion to TAT was the reduction of 2,4-diamino-6-nitrotoluene (2,4-DANT) to triaminotoluene. The reduction proceeded via 2,4-diamino-6-hydroxylaminotoluene (DAHAT) as an intermediate. The intermediary formation of DAHAT was only observed in the presence of carbon monoxide or hydroxylamine, respectively. The reduction of DAHAT to triaminotoluene was inhibited by both CO and NH2OH. The inhibitors as well as DANT and DAHAT significantly inhibited sulfide formation from sulfite. The data were taken as evidence for the involvement of dissimilatory sulfite reductase in the reduction of DANT and/or DAHAT to triaminotoluene. Hydrogenase purified from Clostridium pasteurianum and carbon monoxide dehydrogenase partially purified from Clostridium thermoaceticum also catalyzed the reduction of DANT in the presence of methyl viologen or ferredoxin, however, as the main reduction product DAHAT rather than triaminotoluene was formed. The findings could explain the function of CO as an electron donor for the DANT reduction (to DAHAT) and the concomitant inhibitory effect of CO on triaminotoluene formation (from DAHAT) by the inhibition of sulfite reductase.(ABSTRACT TRUNCATED AT 250 WORDS)
