Arc deposition, a widely used surface coating technique, has disadvantages such as large droplet size and high deposition temperature. Recent trend in its renovation is the introduction of pulsed bias at the. substrate. The present paper attempts to describe the deposition process of TiN films using this technique with emphasis laid on the understanding of the basic problems such as discharge plasma properties, temperature calculation, and droplet size reduction. We show that this technique improves the film micro structure and quality, lowers deposition temperature, and allows coatings on insulating substrates. After analyzing load current oscillation behaviors, we have determined that the plasma load is of capacitance nature due to plasma sheath and that it is equivalent to a circuit element consisting of parallel capacitance and resistance. At last, we point out the remaining problems and future development of the pulsed-bias arc deposition technique.

　　Introduction Various theories of migraine pathogenesis have been developed over the years. To this date, none fully explains all the migraine phenomena. A complete description of each proposed theory is beyond the scope of this chapter. Nonetheless, a brief description of the arguments for and against the leading theories is noteworthy　　……

The development of new drugs for therapeutic purposes has become very expensive and time-consuming in American and European *** is estimated that on the average 50 to 100 million dollars and 10 or more years from the time of patenting are required to make a new drug available for general prescription. Every new drug needs to be charac-

研究了从锌厂废渣（IPR）中回收锌和铅的方法。将Zn、Pb、Fe质量分数分别为11．3％、24．6％、8．3％的废渣，先用硫酸与渣混合并经焙烧、水浸及最后用NaCl溶液浸出。首先研究了焙烧的作用及浸出参数对回收锌的影响。将质量相等的H2SO4／IPR在200℃下焙烧30min，随后对固体质量分数为20％的浆体在25℃下水浸6min，锌的回收率达86%。

HARVESTING AND EXTINCTION IN MULTI-SPECIES ECOSYSTEMS

Social Work and Social Welfare from a multidisciplinary Perspective -- A Challenge for Researchers

第三世界生态高峰会

作者： Potts m.d. University miami USA

A potential cost of harvesting in multi-species ecosystems is that it might cause nonharvested species at the same trophic level to go *** analytical m.d.ls are not well-suited for studying this harvest externality because they focus on species interactions across trophic levels instead of within *** identify the conditions under which the harvesting of one species causes at least one extinction of a nonharvested species at the same trophic level. We compare two harvest regimes:uniform management,in which an optimal harvest rate is applied to the entire ecosystem;arid specialized management,in which a portion of the ecosystem is converted to a monoculture and the rest is left *** regime is more likely to result in extinction depends on the discount rate,net harvest prices under the two regimes,and the harvested species's competitive ability and colonization rate compared to those of the other species

Social Work and Social Welfare 2019年第1期1卷 1-3页

作者： Nicola mucci, m.d., Ph.d University of Florence Florence

In 2008, a deep economic crisis started in the US and rapidly spread around the world. The financial and economic crisis, called “The Great Recession”, continues in many countries today and has been considered as the most severe recession in the history of US (after “The Great depression”). The crisis brought very fast growth in unemployment and it is foreseeable that it will be long lasting and that recovery will be very slow. Hence, such economic change obviously had a significant impact on workers worldwide.
