The Chelyabinsk Metallurgical Combine has periodically used Kachkanar agglomerate to make conversion pig iron since 1972.
Use of this material reached a peak in 1998, when it comprised an average of 27.1% of the charge. In some months, the amount
of this material charged into the furnace reached highs of 45.6 and 74.1% on certain furnaces. The coolers on the iron notches
of furnaces 4 and 5 burned during that year, the quality of the smelting products and the condition of the ladles rapidly
deteriorated, and the smelting rate declined. No Kachkanar agglomerate was used in 2000–2001, but it was again added to the
charge in February 2002. The amount used was smaller than previously, averaging 10.7% for the shop as a whole. It was determined
that using a charge with 15% Kachkanar agglomerate has both positive and negative consequences.
N. N. Gorshkov, A. V. Denisov, and V. Kh. Barinov also participated in this study.

The report deals with the development of procedures, evaluation of laser application and prevention of complications involved in intensive chemoradiation therapy of neoplasms of hemopoietic and lymphoid tissue in childhood. The clinical data on 548 patients, aged 2 months-15 years, with leukemia and solid tumor were evaluated. Laser application for treatment of different complications of chemoradiation therapy of pediatric leukemia proved a valuable innovation. It had a pronounced antiinflammatory and analgetic effect, promoted tissue regeneration processes and cut down the duration of complication treatment drastically. 相似文献

Increasing attention at oil refineries is being focused on solving environmental problems caused by stiffening of the requirements
for emissions of harmful substances into air and water. Advanced technologies that reduce the effect of industrial enterprises
on the environment to the minimum are becoming increasingly in demand. Treatment of process wastewaters to remove hydrogen
sulfide and ammonia is one such problem of the modern refinery with cat crackers.

It has been shown that changes in the orientation of arterial smooth muscle cells during a constant longitudinal stretching of the artery in vivo are not similar in different sections of the stretching zone. Cells in the proximal and distal sections keep their orientation but this orientation differs from that of smooth muscle cells in the control arteries. Cells in the central part of the stretching region lose their definite orientation to settle randomly. 相似文献

This study examines the nature and extent of the relationship between stress levels and intentions to participate in a worksite smoking cessation program among male current smokers (n = 220) employed in an automobile manufacturing plant. A plantwide survey was conducted which measured job stress, nonjob stress, smoking behavior, and intent to participate. The results of polychotomous logistic regressions suggest that among the current smokers in this plant, job and nonjob stress were positively associated with workers' intentions to participate in a worksite smoking cessation program. Thus, contrary to the popular notion that stress diminishes the motivation to quit, employees under high levels of stress may be most receptive to educational interventions intended to persuade smokers to commit to quitting. 相似文献

Changes in the activity of acid phosphatase (AP) and its isoenzymes (tartrate-insensitive AP and formalin-insensitive AP) were investigated in patients with food poisoning in the course of the disease. The activity of AP and its isoenzymes in the serum started to grow in early convalescence and reached maximum in late convalescence. Total activity of AP in food toxic infections consists primarily of the activity of its platelet fraction. AP activity may serve as an additional criterion to predict vascular platelet involvement of hemostasis. 相似文献

Catalytic oxidation of sulfide ions over nickel hydroxides 总被引:2,自引:0,他引:2
The catalytic sulfide ion oxidation by oxygen to elemental sulfur over β-Ni(OH)2 and LiNiO2 has been studied. As a result of experimental investigation performed, a reaction mechanism is suggested which involves heterogeneous and homogeneous processes. Dioxygen activation in the heterogeneous process proceeds via a redox Ni2+ ↔ Ni3+ transition and participation of OH− groups. The active HO−2 species thus formed carries on the reaction in homogeneous phase. Nickel hydroxides are promising catalysts for practical application. 相似文献

The catalytic activity of a wide range of transition metal oxides in oxidation of sulphide ions by air in aqueous medium was studied. Some specific features of the reaction mechanism on some of the studied oxides were considered. The transition metal oxides are promising catalysts for practical application. Some of these oxides will allow the preparation of catalysts possessing activity comparable to that of the cobalt phthalocyanine based catalysts, popular in industrial practice. 相似文献
