制造牙轮钻头用的EX55钢

石油机械 1984年第5期 58-59页

作者： Stanley R.Scales ,daniel E.Diesburg ,朱丹

早在1972年,人们就已经认识到,制造碳化钨镶齿牙轮钻头的牙轮需要一种高淬透性的渗碳级新钢种。这是因为: 1.已经在钻头上应用的碳化钨齿伸出较长,并且切削端形状多种多样,这就要求有屈服强度高的钢材来保证碳化钨齿在压配中得到足够的... 详细信息

幸运指的是什么呢?幸运通常是指某人没有通过真正的努力就获得了珍贵的东西,某人在恰当的时间出现在合适的地方,找回了一幅丢失的名画,或者买了彩票中了奖——这样的人是幸运的人。他们遇上了事前没有预料到的幸运的事。

Coastal zones are very dynamic and fragile environments, constituting a landscape ever more heterogeneous, fragmented and with increasing levels of complexity due to the changing relationship between man and nature. Integrated coastal zone management therefore requires detailed knowledge of the system and its components, based—to a large extent—on technical and scientific information. However, the information generated must be in line with the political requirements necessary for decision-making and planning. Thus the use of indicators to give a simplified view of the many components of the territory, and at the same time to provide important information about patterns or trends, becomes a tool of the utmost importance. These indicators can be understood as measurable characteristics of the environment, which facilitate comprehension of the processes occurring at different scales and serve as a reference to inform the population and support decision-making. The aim of the present note is to demonstrate briefly the need to develop geographical-environmental and natural risk indicators to facilitate comprehension of the dynamic of spatial and temporal landscape patterns, particularly in coastal environments. This approach offers an historical summary of the natural, socio-economic and political processes which currently make up the territory, and which without doubt will continue to influence it in the future. At the same time, it is proposed that information should be integrated on the basis of this framework with a view to generating spatial decision support systems in a context of planning and integrated management of the coastal zones of Chile.

Introduction: According to WHO, globally an estimated 585,000 women die each year from complications of pregnancy and childbirth. One of the targets of Millennium Development Goal 5 (MDG 5) is to reduce maternal mortality by three quarters of the 1999 value by the year 2015. However, three years to 2015, very little is known on the trends in maternal mortality ratio, causes of maternal deaths and their associated factors in the Tiko Cottage Hospital (TCH) and Limbe Regional Hospital (LRH) in the South-West Region, Cameroon. Methods: This was a retrospective, analytical cross-sectional study that was carried out from 1st January 2000 to December 2012. After obtaining ethical clearance, the records of cases of maternal deaths and a reference group of women who survived after a pregnancy during the same period were carefully reviewed. The data were analyzed with SPSS 10 and EPI 3.5.1. Results: There were 14,480 live births and 132 maternal deaths during the study period, giving an adjusted Maternal Mortality Ratio (MMR) of 892/100,000 live births. Patients’ age ranged from 15 - 40 years (SD 2.3). We observed a downwards trend of Maternal Mortality Ratio (MMR). Seventy-eight percent of the maternal deaths were due to direct causes. The triad of hemorrhage (54.5%), abortions (17.4%), and eclampsia (10.6%) was the leading cause of death. HIV-related complications and hepatitis constituted the main indirect causes of maternal death. In 85.4% of cases, maternal deaths were avoidable. Lack of blood for transfusion and late referral of cases were the main avoidable factors. Patients less than 35 years (p = 0.01), no antenatal care (ANC) (p = 0.001), unemployment [OR = 1.52;95% CI: (1.38 - 48.28);p = 0.02] were significantly associated with maternal deaths while grand multiparity [OR = 1.20;95% CI (0.30 - 4.86);p = 0.79], marital status [OR = 1.20;95% CI: (0.70 - 2.07);p = 0.51] and education level were not significantly associated with maternal deaths. Conclusion: The trend s

欧盟的法律规定,只有在兽医的指导下方可在仔猪饲料中使用治疗剂量的ZnO。本案例的经验表明,不足200 mg/kg的ZnO添加量不足以预防断奶仔猪感染产肠毒性大肠杆菌。在相关疫苗还没有表明其充分的预防效果前,发生在一年前欧洲某猪场的本案例,其教训仍值得人们的借鉴。
