高炉无料钟布料凸台料面模拟研究

以某高炉为研究对象,根据其主要参数条件、装料制度,应用无料钟多环布料数学模型模拟研究了炉料在炉内的初始分布,寻求中心较开放的凸台料面。研究发现:边缘增加布料圈数和溜槽大角差布料以及边缘矿增加布料圈数、增加焦炭布料溜槽角度和溜槽大角差布料方法可获得较平坦的凸台料面。采用减少布料溜槽角度布料方法时,调整布料参数一般难以获得中心较开放的凸台料面;采用增加焦炭布料溜槽角度布料方法时,缩小布矿焦溜槽角度,增大矿焦布料溜槽角度差易获得中心较开放的凸台料面。在生产中应用本模型将有助于炼铁高炉工作者定性和定量运用上部调剂控制炉料在高炉炉内的初始分布,达到保护炉墙、保证高炉顺行、改善煤气利用、节能降耗的目的。

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.
