CONSERVING RARE IRIS SPECIES

Annali di Botanica , 2000,
Abstract: In rare Iris species, there are problems of conservation and estimation. Other difficulties with such species are germination and repatriation to the wild state in regions where they have become extinct.
Calcium antagonists in the treatment of arterial hypertension during pregnancy
R.I. Striuk
Rational Pharmacotherapy in Cardiology , 2006,
Abstract: According to WHO data, arterial hypertension (HT) is revealed in 15-20% of pregnant women. In different regions of Russia the incidence of pregnancy HT varies from 7 to 29%. In women with HT started before pregnancy, perinatal losses are observed in 3, 8%, premature births — in 15, 3% and intrauterine growth retardation — in 16, 6%.Physiological gestational changes of hemodynamics are described. Hypertensive pregnant patients of high and low risk are defined. Non-pharmacological treatment of pregnant women with HT is presented in details. Antihypertensive therapy may not be used in hypertensive patients of low risk with blood pressure (BP) of 140-16090-110 mm Hg. If BP is higher antihypertensive therapy should be used immediately.Dihydropyridine calcium antagonists (CA) is drugs of choice for HT treatment during pregnancy, especially “advanced” CA of the third generation. They have predictable efficacy. It is possible to use short-acting nifedipine for treatment of acute HT in pregnant patients.
Effect of Salinity and Wytch Farm Crude Oil on Paspalum conjugatum Bergius (Sour Grass)
R.I. Ibemesim
Journal of Biological Sciences , 2010,
Abstract: The objective of this study was to investigate the individual and dual effect of salinity and Wytch Farm Crude oil on the growth and ion balance of Paspalum conjugatum. Increase in salinity resulted in a significant (p<0.05, Tukey HSD) decrease in dry weight of both aboveground and belowground tissues. Plant mortality was recorded between 43 and 64% ASW. Increase in salinity resulted in a significant (p<0.001, Tukey HSD) increase in aboveground Na+ concentration to a maximum of 3.2 μM mg-1 dw in 64% ASW treatment compared to 0.63 μM mg-1 dw Na+ in 14% ASW treatment. Paspalum conjugatum survived Low oiling (Lo) but Heavy oiling (Ho) resulted in mortality. The interactive effect of oil and salt was detrimental to the growth of Paspalum conjugatum and significantly decreased K+ concentration and K+, Na+ ratio.
蒸汽发电厂中的冶金学发展
R.I.Jaffee
金属学报 , 1979,
Abstract: 1978年11月13日美国冶金科学家访华团R.I.Jaffee博士在北京做了“蒸汽发电厂中的冶金学发展”的学术报告,受到热烈欢迎。报告分三部分(1)蒸汽发电厂的发展趋势及相关的冶金学问题;(2)用于低压透平末级叶片的钛合金;(3)透平转子和发电机的大锻件。本刊编辑部征得R.I.Jaffee博士同意,发表报告记录稿,供国内广大读者阅读参考.这份报告记录稿,整理以后未经本人审阅。我们希望这份报告发表在本刊上,将有助于加强中美两国冶金科学家之间的学术交流。

在大气及真空中工作的电机电刷的磨损试验结果
R.I.Christy,郑冀
摩擦学学报 , 1989,
Abstract: 航天器大上多数小型直流电机,至今只要求在真空环境中工作。但随着航天飞机的发展,小型传动电机必须在地面及空间环境中都工作。本文报导了评价小型直流电机电刷在大气及真空中的性能试验。根据研究和对销售者的调查,选出13种候选的电刷材料。将永磁电机与并励电机耦联起来,用以考察每种电刷材料。监测了在大气及真空中工作时的电机性能,并在每个试验间隔测量了电刷的磨损。在13种最初的候选材料中,有2种不能加工成电刷,3种呈现出高磨损,剩下的8种是可以采用的。其中有一种材料比其它的要好得多。因此在很多航天器中有可能使用本来就简单、便宜的电刷电机来代替复杂的无刷直流电机。但在任何特殊应用之前,这些成功的候选材料还要作进一步的鉴定性试验,如振动、温度试验等。
