安钢1号高炉焖炉及复风操作

对安钢1号高炉焖炉及复风操作进行了总结。1号高炉先后焖炉、复风4次,最长的1次焖炉时间为47天。通过制定安全合理的焖炉方案、落实焖炉期间管控、充分做好复风准备、严格控制恢复炉况过程的操作和管理,1号高炉在47天焖炉后安全、顺利复风,仅4天就恢复全风生产。认为,高炉炉缸区域铁口与风口的贯通是焖炉后具备送风条件的基础,合理的送风制度、装料制度、热制度和造渣制度是长期焖炉后恢复炉况的关键。     

新钢10号高炉锌平衡分析及应对措施

对新钢10号高炉高锌负荷对炉况的影响及应对措施进行总结。通过严格控制入炉负荷、优化布料矩阵、适当降低碱度及强化炉前管理等措施,保证了10号高炉在高锌负荷情况下炉况长期稳定顺行。     

湘钢新3号高炉炉况波动的原因及对策

对湘钢新3号高炉炉况波动的原因及对策进行了总结。高炉炉况波动的主要原因一是原燃料质量劣化,二是块状带气流分布异常,三是操作炉型不合理。结合新3号高炉采用非中心加焦模式生产的状况,上部以调整气流为重点,下部以活跃炉缸为重点,通过不断优化上下部操作制度,高炉炉况逐渐恢复稳定。认为高炉要保持长期稳定,需要下部送风制度和上部装料制度合理匹配。     

梅山2号高炉脱湿鼓风技术的应用

对梅山2号高炉脱湿鼓风技术的应用进行了总结。梅钢2号高炉长期保持1220±5℃的全风温操作,富氧率维持在1.5%±0.20%,冷风流量为2400±50Nm~3/min,脱湿后的鼓风湿分为9g/m~3,通过适当调整风口理论燃烧温度,可保证炉缸活跃、炉况顺行、提高喷煤比、降低焦比、降低铁水成本。     

Laudatio: Prof. Dr. med. Dr. phil. Dres. h. c. Heinz H?fner

During the course of a year, there are many healthcare workers nationwide who sustain sharps injuries whilst carrying out their duties. Staff who work in the Accident and Emergency (A & E) units are no different from anyone else in this respect. The emotional cost of such an accident cannot be calculated, whereas the financial costs can. This article aims to show how the cost of an injury to a member of staff can be calculated, thus allowing a manager to assess the financial implications of sharps injuries to their department. In the absence of access to an Occupational Health (OH) department, most A & E units have to respond to sharps injuries to healthcare workers in the hospital. This task must be attended to by the medical staff as well as the nursing staff of the A & E unit. Within the following text the appropriate responses and methods to ensure uniformity of response are discussed. The tables and the calculation figures shown are taken directly from the information held in the St James's University Hospital Trust's OH department. All calculations are based on the middle band of the salary scale for each discipline. Accurate costings for each member of staff injured cannot be shown in this article, but the general principle is laid down and can be easily followed for any situation.

The blood-brain barrier. I. Histology. Physiology. Embryology. Transport

The concept of blood-brain barrier (bbb) arose in the beginning of the 20th century after report that the dyes injected intravenously did not appear in the brain. The idea and definition of bbb has been changed many times since then. We present current opinion concerning bbb, its histology, embryology, ultrastructure and function on the ground of a review of the recent literature.     

Rats, Man . . .

Comments on the article by Richter entitled "Rats, Man, and the Welfare State" (see record 1960-02810-001). The commenter notes that in his article Richter did not indicate how hereditary and environmental factors were controlled. In comparing the hereditary survival characteristics of wild versus domesticated rats, it would be essential that the environmental influences on the survival characteristics of the wild rats should be ruled out. Another factor to be considered is that the wild state may offer a diet and other environmental influences, which in the life of a single individual would produce organic changes, accounting for some of the differences between wild and domestic rats. It would seem that the most effective way to determine the hereditary differences between wild and domestic rats would be to create a wild group, composed solely of the offspring of wild rats.

C.A.T. scans

With the rapidly mounting cost of medical care in hospitals, physicians must seek alternative forms of therapy for illnesses that could conceivably be treated by less confining methods. One appraoch to this problem is the Psoriasis Day Care Center, where psoriasis patients with extensive disease are treated during the day and allowed to return home at night. The advantages include reduced cost, accessibility for more patients, and superior therapeutic results. This day care center concept could be equally applicable to other diseases now routinely treated by complete hospitalization.
