2000m~3高炉开炉生产实践

对天钢2000m~3高炉开炉生产实践进行了总结,通过制定合理的开炉方案,做好了严密的开炉准备,实现了安全、高效、科学的开炉。开炉后,通过合理的上下部调节,稳定的热制度,实现了炉况顺行,快速达产,取得了良好的经济效益。本次开炉首次使用了铁口预埋氧枪技术,开炉9小时42分后铁口顺利出铁,与以往开炉相比大幅度降低了炉前的劳动强度,对开炉后的快速达产也起到了促进作用。     

Intravascular coagulation. 2. Underlying conditions and therapy

Therapy for intravascular coagulation is directed primarily against the underlying disorder. If the latter is not readily correctable or if the patient is bleeding actively, anticoagulation with intermittent administration of heparin by the intravenous route is indicated. If thrombocytopenia is present, heparinization must be accompanied by platelet transfusion. The efficacy of therapy is judged by the cessation of bleeding or thrombosis, improvement of organic dysfunction, and correction of the levels of the coagulation factors, particularly factor V and fibrinogen.     

Discussion 2.

Discusses the three articles in this miniseries by Meyers (see record 1989-17318-001), Phillips (see record 1989-17118-001), and Genshaft and Wiesniewski (see record 1989-17107-001), which have a remarkable degree of agreement in some truly significant ways. The author also comments on continuing specialty identification problems and interspecialty relationships. All the articles emphasize an expanded view of school psychology for the future. Practice, instead of being limited to the school setting, is viewed as being conducted over the entire range of schooling, from preschool to schools; to other community agencies, institutions, and situations; to higher education; wherever children, adolescents, and adults are involved in the activity of schooling. Education and training in school psychology are seen as moving beyond exposure to a cafeteria of courses and a limited number of techniques to broaden and deepen education designed to serve both professional and practical goals. The treatment of credentialing and licensure in one article befits the wide ranging practice projected in another. Although admirable for the insight that they demonstrate, some of the articles have blindspots or major omissions, which are also discussed here.

The reaction of NO. with O2.- and HO2.: a pulse radiolysis study

The reactions of NO. with O2.- and with HO2. were studied using the pulse radiolysis technique under pseudo first order conditions where ([O2.-]o + [HO2.]o) > [NO.]o at pH 3.3-10.0. The rate constant of the reaction of NO. with O2.- was determined both by monitoring the decay of O2.- at 250 nm and the formation of ONOO- at 302 nm to be (4.3 +/- 0.5) x 10(9) M-1s-1, independent of ionic strength and pH in the range of 6.1-10.0. The rate constant of the reaction of NO. with HO2.- was determined by following the decay of HO2. at 250 nm to be (3.2 +/- 0.3) x 10(9) M-1s-1 at pH 3.3.     

Type 2 diabetes: treatment goals and pharmaceutical therapies. 2

The most important treatments for type 2 diabetes remain weight reduction and physical activity, but an increasing armamentarium of drug therapies has much improved our ability to control blood glucose levels. Each of the known metabolic defects in type 2 diabetes can now be treated by different classes of drugs. Although the side effects of these drug therapies are relatively mild and infrequent, physicians need to be on guard for possible problems. Primary care physicians can manage most patients with type 2 diabetes. Specialists in endocrinology, ophthalmology, and podiatry are valuable resources.
