    Notes: Studies immersion gold over electroless nickel, immersion gold over electroless palladium, immersion gold over electroless palladium over electroless nickel, immersion gold over immersion silver and immersion silver. In the palladium finishes, two palladium thicknesses were evaluated: 10-12µin. and 18-20µin. Multiple plating chemistry suppliers provided plated test vehicles. HASL and OSP test vehicles were included as control samples. In total, 14 finishes were evaluated in the test matrix. The test vehicle was a daisy chain of zero ohm 1,206 chip resistors that could be monitored individually. Test vehicles were assembled using 63Sn/37Pb eutectic solder paste on an automated assembly line. The thermal cycle range was -40°C to 125°C with 30-minute transition times and 15 minutes at each extreme in a single chamber air system. For each test matrix cell, 120 zero ohm resistors (40 from three boards) were continuously monitored for electrical failure (〉100ohms). In addition, resistors were sheared from test vehicles and the shear force at failure was recorded. A decrease in shear force did occur with thermal cycling due to crack initiation and growth in the solder joints. Solder joint cracks have also been examined.

    Notes: The Fe2 molecule is a typical transition metal dimer which has a rather large dissociation energy and a small bond distance compared with the inter-nuclear distance in the crystalline metal. We have investigated the Fe2 molecule with multireference self-consistent-field (MCSCF) and multireference configuration interaction (CI) calculations. The dissociation energy (De), the equilibrium nuclear distance (Re), and the zero-point frequency (ωe) were calculated (with observed in parentheses) as 1.57 (1.30±0.22) eV, 2.06 (1.87 to 2.02) A(ring), and 260.9 (299.6) cm−1, respectively. Thus the agreement between experiment and calculation is very satisfactory, and is a marked improvement on previous theoretical studies. The contribution of the d electrons to the bonding is important and a proper description of correlation effects among the d electrons is indispensable.

    Notes: Cholesterol may affect the activity of microbial toxins in a direct, specific way, or it may exert indirect effects because of its role in membrane fluidity, membrane line tension, and in the stabilization of rafts in the cytoplasmic membrane. The thiol-activated toxins of gram-positive bacteria, and the cytolysin of Vibrio cholerae are presented as examples of specific toxin-cholesterol interaction. Several mechanisms of indirect effects of cholesterol are discussed using examples such as Staphylococcus aureusα-hemolysin, aerolysin, and diphtheria toxin.

    Notes: In the post-Mao era, one highly significant dimension of China's official programme of reform and integration into the international economy has been a commitment to legal construction. This commitment has included a sustained effort to fashion a basic corpus of environmental protection law alongside supportive institutions, administrative norms and policies, in order to create a “basic legal system of environmental protection” (huanjing baohu de jiben falii zhidu).' In the eyes of the authorities in the People's Republic of China, such efforts reflect a degree of environmental concern that is unusually strong for a developing society.2 China's achievements, we are often told, must be placed in the context of the considerable difficulties the PRC faces in terms of the pressing need to raise living standards, a serious problem of over-population, a shortage of natural resources, an outdated industrial infrastructure and poor industrial management.3 Of course, viewed comparatively, the PRC's embrace of environmental protection law was somewhat belated,4 only properly commencing after its participation in the 1972 United Nations Conference on the Human Environment held in Stockholm. The subsequent expansion of environmental legislation and enforcement has been some-what erratic. Nevertheless, there appears to be a continuing intent to fashion a substantial body of environmental law, and concern with the construction and revision of this was further enhanced by China's participation in the 1992 UN Conference on Environment and Development, held in Rio de Janeiro. Following this, Premier Li Peng “made a commitment to conscientiously implement resolutions adopted at the Conference”5 and, given the PRC's very substantial size and population, a positive embrace of internationally acceptable standards of environmental welfare is highly significant for future global environmental protection. This article examines the principal features and significance of the PRC's domestic environmental protection law, and considers briefly the implications of the Chinese approach to environmental law for understanding the development of law more generally in post-Mao China.

    Notes: This article examines developments in the family law of post-Mao China. The expansion of the legal regime governing Chinese family life during the past 15 years has been extremely rapid and represents an important legal advance, although to some extent the developments are old wine in new bottles - a reconstruction in legislative form of pre-existing administrative norms already governing family life. In addition, the article necessarily considers a number of significant tensions or contradictions that have become apparent in PRC family law over the past decade or so.At one level the post-Mao growth in the corpus of family law has a fairly clear meaning. The 1950 Marriage Law and the system of family law which it attempted to put into place were important elements in the generation of political support for the new regime. However, in the post-Mao era the rapid codification of family law has been in large part prompted by the leadership's concern to ensure stability, order and continuity in social life. In addition, the family has once more been installed as the basic unit of social life, a position enhanced by the declining social significance of the danwei or unit. The law has therefore been used to reshape the family in order to make it more consistent with the new economic and social orders being created in the era of reform. There is also a concern to strengthen the rights and interests of the socially vulnerable, and this too has influenced certain areas of family law.

    Notes: [Auszug] In Drosophila melanogaster, ageing is slowed when insulin-like signalling is reduced: life expectancy is extended by more than 50% when the insulin-like receptor (InR) or its receptor substrate (chico) are mutated, or when insulin-producing cells are ablated. But we have yet to resolve when ...
