Slag conditions in electrosmelting: A review

The literature on the foaming of electrofurnace slag is reviewed. On that basis, recommendations for improvement in slag foaming are formulated. Inconsistencies in the published data are noted, and some principles are elaborated. It is evident that two key factors have been ignored in the existing research: the temperature of the slag; and its content of small gas bubbles.     

Determining the composition of electrosmelting dust

The elementary composition of electrosmelting dust is determined by atomic-emission spectrometry with inductively bound plasma, by an IR absorption method, and gravimetrically. On the basis of these data, the elementary composition may be converted so as to establish the content of metal oxides, and the content of oxygen in the dust may be determined. More complex compounds may be identified by reconstruction of the dust composition on the basis of Terra software.

The generations of psychotherapy research: An overview.

Psychoanalytic therapy research can be divided into 4 generations, marked by increasing conceptual sophistication and technological enhancement. The 1st generation (1917–1968) comprised simple retrospective counts of improved outcomes by unspecified criteria. The 2nd generation (1959–1985) consisted of 2 kinds: (1) prospective group-aggregated studies of psychoanalytic treatments, with specified definitions, operationalized criteria, and predictions to expected outcomes, and (2) individually studied outcomes in a sequence of patients. The 3rd generation (1954–1986) combined both kinds of 2nd-generation studies with the added feature of separating outcomes at termination from the more enduring effects at subsequent follow-up. The 4th, current generation (1970s–) adds in microanalytic process studies made possible by recent technological advances-audiotapes, combined with computer searches. Programs are currently being fashioned to combine these ongoing process studies with the best outcome measures in order to realize the principle of Patient-Treatment-Outcome Congruence, the representation of the patient's illness, the treatment process, and assessed outcome in comparable terms.

广东省建筑用钢材质量的现状

通过对全省约60家钢厂的建筑用钢材的质量抽查，认为基本达到相关产品的国家标准或行业标准；但在钢材的包装、标志方面，很多钢厂不够重视．由于受市场因素影响，整个行业普遍生产“负公差”钢材．通过对抽查钢材进行化学成分和物理性能试验、分析、统计表明：热轧带肋钢筋合格率达94．4％，钢筋力学性能σs、σb略高出标准50～70MPa，冷弯合格率很好．冷轧带肋钢筋和冷轧扭钢筋的合格率分别为62．5％，78．6％，此类钢筋力学性能整体偏高，不合格的主要因素是冷弯开裂、延伸率低．热轧再生钢筋合格率为90．9％，我省这类钢筋的产量很少．热轧盘条和热轧光圆钢筋的合格率均为100％，显示我省生产这两种钢筋已达到较成熟的水平．     

Extraction of zinc and iron from electrosmelting dust

The extraction of zinc and iron from dusty electrosmelting wastes is discussed. The chemical composition of the dust is investigated. Methods of obtaining zinc- and iron-bearing products by reduction are identified. The optimal conditions for the generation and capture of zinc sublimates are determined. A system for processing steel-smelting dust to obtain iron is proposed. Simultaneously, this technology extracts zinc from the dust in the form of zinc-oxide concentrate.     

Processing of electrosmelting slag in a ball-packed drum

The processing of steel-smelting slag involves discharge of the slag melt from the furnace, its transportation, cooling, and solidification, the extraction of large nonmetallic aggregations, crushing, sorting, magnetic separation, and storage of the final products. It requires energy-intensive equipment and special buildings: slag doors, gantries, pits, crushing and sorting systems, and stores, which occupy considerable space in the production buildings and require the attention of qualified staff. A much simpler approach is to process molten electrosmelting slag.     

Subliminal stimulation: An overview.

"Seldom has anything in psychology caused such an immediate and widespread stir as the recent claim that the presentation of certain stimuli below the level of conscious awareness can influence people's behavior in a significant way." Recent history relating to the technique is discussed under the topics of Recent Advertising Demonstrations, Research on Behavior without Awareness, and Effects of Inner States upon Thresholds. Unanswered Methodological Questions and The Ethics of Subliminal Influence are the other major topic areas. "The indiscriminate and uncontrolled application of psychological principles is increasing at a fearsome rate in the form of motivation research, propaganda, public relations, and a host of other useful practices based on the work of psychologists." Psychologists have a responsibility for assisting society to use its findings wisely. 132 references. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The Psychotherapy Research Project of the Menninger Foundation: An overview.

Studied processes and outcomes of psychoanalysis and psychoanalytic psychotherapy, both expressive and supportive. 42 Ss were followed via initial, termination, and follow-up studies over the entire natural course of treatment, with 100% follow-up 2–3 years posttermination. Some follow-ups extended over the 30-year life span of the study. Detailed case histories and life histories were obtained from all 42 Ss. Psychoanalyses achieved more limited outcomes than predicted; psychotherapies often achieved more than predicted. Supportive mechanisms infiltrated all therapies, psychoanalyses included, and accounted for more of the achieved outcomes (including structural changes) than anticipated. An expanded new categorization of supportive therapeutic mechanisms is proposed, along with an elaboration of expressive therapeutic mechanisms.

An overview of pharmacoepidemiology

Pharmacoepidemiology is the application of epidemiological principles and methods to the study of drug effects in human populations. The goal of this discipline is to characterize, control and predict the effects and uses of pharmacological treatment modalities. Pharmacoepidemiology is also concerned with the economic impact and health benefits of unintended drug effects. The increasing importance of pharmacoepidemiology has been created by the need to develop a more accurate portrait of how drugs are used in the general population. Sophisticated and potent drug therapies require surveillance beyond the scope of the carefully controlled clinical trials of Phases I, II and III. Case-control and cohort studies, which allow scientists to evaluate the effects of patient variables on clinical outcomes, provide a wealth of information regarding the study of unexpected drug effects, drug utilization, treatment costs and the individualization of therapy.     

High speed continuous casting of steel billets: Part 1: General overview

Abstract

This paper is the first of a series of two, providing an overview of the results of mould heat transfer analyses conducted over years of industrial trials. The effects of casting speed, carbon content, superheat, water flowrate, electromagnetic stirring, and mould lubricant are discussed in terms of the midface mould heat transfer. Mould corner heat transfer is also discussed. Finally, an overview of mould design is given, as well as an analysis that reveals that both excessively steep and shallow meniscus tapers cause high heat transfer. Alternative designs to the conventional straight tapered moulds are discussed briefly. The focus is on the primary cooling zone, and therefore billet quality issues are not extensively covered.     

The acute abdomen. An overview and algorithms

The diagnosis and management of the patient with an acute abdomen remains one of the most difficult challenges for the surgeon. A thorough understanding of the anatomy and physiology of the abdomen are essential to properly generate a differential diagnosis and to formulate a treatment plan. While recent advances in technology can be extremely helpful in certain situations, they cannot replace a physician's clinical judgment based upon a good history and physical examination. This article provides a general overview of the evaluation of the patient with an acute abdomen. It will also suggest algorithms to consider in the diagnosis and treatment of these patients.     

The psychosocial impact of skin disease. An overview

When the skin is disfigured by disease, it has an impact on the afflicted person. The intensity of the effect depends on many variables including the natural history of the disease, the characteristics of the individual patients and their life situation, as well as the attitudes and assumptions of the culture at large about the meaning of skin disease. Fantasies about skin disease, shared by patients and onlookers alike, relate to guilt, control of bodily boundaries, and perfectionist yearnings. Some issues involved in these fantasies include distortions about contagion, dirt, and sexuality. Ways of helping patients to manage the impact of their skin disease include an empathic doctor-patient alliance, education of patients and the community, and if indicated, referral for psychiatric consultation.

Homosexuality and psychopolitics: An historical overview.

Traces various sources of attitudes toward homosexuality (HMSX) throughout history and explores the scientific and political forces that contributed to the depathologization of HMSX in the psychological community via the American Psychological Association. Advances in the understanding of lesbian and gay issues within psychology since the early 1970s are considered, as well as an analysis of the current state of attitudes toward HMSX within professional psychology. Attitudes toward HMSX within psychology have changed from viewing HMSX as a form of mental illness to considering gay males and lesbians to be an oppressed group in need of special considerations. However, more attention needs to be paid to the diversity within the lesbian and gay male populations in terms of race and ethnicity, religious diversity, class issues, and physical, emotional, and cognitive disability.
