发达国家物流标准化建设对我国的启示

近年来,随着“第三利润源泉”被越来越多的人所熟悉和了解,现代物流作为与金融、电子商务并列的三大朝阳产业,受到了前所未有的关注和重视。我国现代物流业也因此得到了较大的发展,但同物流发达国家相比,还存在差距,尤其在物流标准化研究和实践方面,差距更为明显。“它山之石,可以攻玉”。考察物流发达国家在物流标准化方面的一些成功经验,对我们的标准化建设也许具有一定的借鉴意义。一、发达国家的物流标准化现状1.加拿大:重点整合物流标准体系地处北美的加拿大发展现代物流业的时间较早,目前已建立起了包括物流用语、物流基础设施和装备…

区域物流产业与区域经济发展

经济的高速发展,使现代物流业等到了很多大发展空间。同时随着经济的跨区域发展和全球化进程,使得企业对物流业的要求也越来越高,单一的物流企业已经不能满足社会对物流的需要。实现经济区域内的物流整合与结合,实现产业集群效益,提高物流企业的整体竞争力和效益,将对区域内物流企业和区域经济都将有促进作用。     

铁路货运向现代物流转型研究

随着经济全球化和电子商务的广泛使用,现代物流业已经快速成长为全球最有潜力和发展空间的新型服务行业。文章以铁路货运与现代物流的对比为出发点,通过两者之间的转型论证,研究并提出了发展现代物流的策略。     

现代物流管理与可持续发展

在传统物流向现代物流快速转型的同时,物流业也被提到了前所未有的高度,越来越显示出其在社会经济发展中的重要作用和战略地位。物流过程是社会和企业经营发展的"第三利润源泉"。在信息技术的支持下,发达国家的现代物流已经成为国民经济发展的重要支柱产业、提高经济效益的重要源泉、产业升级和企业重组的关键推动力、以及区域创新和经济发展支撑环境的关键因素之一。现代物流业作为第三利润已经成为新兴重要产业,加快发展的同时必须注意经济效益和环境效益的统一,把发展绿色物流作为推进可持续发展的一个方面加以落实。本文对现代物流在可持续发展背景下,做以系统研究。     

Gender differences in publication productivity in psychology in India

An analysis of gender differences in psychology in India provides quantitative and qualitative assessment of R&D output contributed by psychologists with the indication of the trend of growth, skewness, relatedness, co-authorship pattern of productivity.     

Metrology in Chemistry in Germany

The system for Metrology in Chemistry in Germany is described. At the national standards level, a network of high-level chemistry institutes coordinated by the national metrology institute, PTB, provides the primary references for chemical measurements. A dissemination mechanism employs chemical calibration laboratories accredited within the framework of the German Calibration Service (DKD). They act as “multipliers” between the national standards level and the user level by providing the user with calibration means which are traceable to the SI via national standards. Traceability structures in clinical chemistry, electrochemistry, elemental analysis and gas analysis are described     

Natural radioactivity in drinking water in private wells in Finland

Natural radioactivity in drinking water was determined in population-based random study of 472 private wells. The mean concentrations of (222)Rn, (226)Ra, (234)U, (238)U, (210)Pb and (210)Po in drilled wells were 460, 0.05, 0.35, 0.26, 0.04 and 0.05 Bq l(-1), and in wells dug in the soil were 50, 0.016, 0.02, 0.015, 0.013 and 0.007 Bq l(-1), respectively. Approximately 10% of the drilled wells exceeded a radon concentration of 1000 Bq l(-1) and 18% a uranium concentration of 15 microg l(-1). The mean annual effective dose from natural radionuclides for a drilled well user was 0.4 mSv and 0.05 mSv for a user of a well dug in the soil. The effective dose arising from (222)Rn was 75% of the total of all natural radionuclides for drilled well users. As regards long-lived radionuclides, (210)Po and (210)Pb caused the largest portion of the effective dose. The dose arising from (238)U, (234)U and (226)Ra was only 8% of the total of all natural radionuclides.

Radioactivity in building materials in Iraq

Activity concentrations of (226)Ra, (232)Th and (40)K in 45 samples of different building materials used in Iraq were measured using gamma-spectroscopy system based on high-purity germanium detector with an efficiency of 40 %. Radium equivalent activity, air-absorbed dose rate, annual effective dose, external and internal hazard indices and alpha index due to radon inhalation originating from building materials were measured to assess the potential radiological hazard associated with these building materials. The activity concentrations of the natural radionuclides (226)Ra, (232)Th and 40K were found to range from below detection limit (BDL) to 223.7 ± 9, BDL to 93.0 ± 3 and BDL to 343.1 ± 12, respectively. Values of average radium equivalent activity, air-absorbed dose rate, indoor and outdoor annual effective doses, external and internal hazard indices and alpha index ranged from 6.5 to 124.9, 16.2 to 89.5 (nGy h(-1)), 0.08 to 0.44 mSv, 0.02-0.11 mSv, 0.09 to 0.53, 0.13 to 0.69 and 0.03 to 0.62, respectively. These values indicate a low dose. Therefore, the building materials used in the current study are quite safe to be used as building materials.     

Optische in situ Schichtdickenmessung in Bedampfungsanlagen. Optical in situ film thickness monitoring in coating systems

Optical film thickness monitoring is more precise than crystal monitoring. The optical measurement makes use of the fact that the intensity of a monochromatic light beam which is reflected on a film will change periodically with increasing film thickness. The measurement is performed at an exchangeable test glass that is positioned beside the substrates and is therefore coated in the same way as the substrates. The accuracy of cut‐off is achieved by a “fit” of a theoretical curve shape to the measured values. Order filters are used to ensure that, at a certain wavelength, higher deflection orders do not influence the measurement when a monochromator grating is used.
