  • A study was performed using density functional theory at the PW91PW91/DGDZVP2 level to investigate the structures and stability of the neutral nitrogen-doped titanium clusters TinN (n = 1-10). The most stable isomers may have spin state ranging from doublet to quartet to sextet. Interestingly, the ground-state structures of these clusters are consistently formed by adding an N atom on an edge and a face of the pure titanium cluster and the N atom prefers to stay on surface of the clusters.

  • The objectives of the present paper are, first, to sketch the broad outlines of how writing skill develops across three stages, as a child matures and learns the craft of composition through late adolescence and into early adulthood. The first two - knowledge-telling and knowledge-transforming - are well documented. A third stage - knowledge crafting - is more speculative, but important for understanding expert or professional levels of writing skill.

  • While there appears to be a rising incidence of problem drinking in the elderly, there are also reports that low risk drinking may provide benefits to older populations. Indeed. arguably most of the supposed benefits of alcohol consumption are to be found in older people. So, for example, the claimed protective effect of alcohol in regard to cardiovascular disease applies to the late middle aged and elderly. For this reason, the recommended optimum level of alcohol consumption for health is higher for the elderly than the young.

  • In the vascular system, estrogen and serotonin have been shown to individually alter clotting, cholesterol, vasocon- striction, and heart attacks. Both high and low levels of E2 have been associated with increased risk of thromboem- bolism; high levels result in increased clot formation, while low levels result in slower clot breakdown. Unusu- ally high concentrations of estrogen (beyond normal physiological levels) directly increase the likelihood of clotting by increasing production of clotting factors VII through X in the liver [41].

  • Ozone (O3) is a secondary pollutant formed in the atmosphere throughout a complex non-linear chemical reaction involving two classes of precursors: the reactive volatile organic compounds (VOCs) and the oxides of nitrogen (NOx) in the presence of sunlight. The rapid urbanization and industrialization in Vietnam have brought about high air pollutant emissions including the O3 precursors. Ground level O3 may already be high in large cities like Hanoi and Ho Chi Minh City. The O3 episode is very important for scene of view of photochemical smog in Hanoi.

  • The risk-free yield curve also has fundamental implications for financial stability. It defines the terms of maturity transformation in an economy. Partly because of regulation, the “safe” assets that banks and institutional investors hold on their balance sheets are largely government bonds. The yield on government bonds will influence other risk exposures taken by the financial industry. And it is long-term rates – not short-term rates – that help determine the prices of long-term assets.

  • The problem of overweight affects more than 1 in 7 youth ages 6 to 17 (Flegal, et al., 2002; Ogden, et al., 2002). A number of factors contribute to this rising rate of childhood overweight; however, scientists and medical professionals agree that poor diet and lack of physical activity play some of the most important roles in children being overweight (Berkey, et al., 2000; Rowlands, et al., 1999). Sub-optimal levels of physical activity and poor ...

  • The ILO gender audit has added impetus to the process of integrating gender equality into the ILO by setting in motion an institutional learning mechanism. The challenge now is to rigorously monitor the implementation of its recommendations. The ILO constituents and the UN system are increasingly interested in conducting gender audits in order to accelerate gender mainstreaming within their own organizations. ILO is responding by modifying and revising the audit methodology to meet their specifi c needs.

  • We use three models to estimate health damages from PM10. First, we use an air dispersion model to estimate each source’s contribution to annual average ambient levels of PM10 at several thousand receptor locations in Paso del Norte. Next, we use a health effects model to estimate the number of cases of human mortality and morbidity that result from this pollution each year. Finally, we use a valuation model to calculate the dollar values of these health impacts. This section briefly discusses each of these models. A more detailed discussion is available in Blackman et...

  • Many youth in the United States have fully integrated the Internet into their daily lives. For them, the Internet is a positive and powerful space for socializing, learning, and engaging in public life. Along with the positive aspects of Internet use come risks to safety, including the dangers of sexual solicitation, online harassment, and bullying, and exposure to problematic and illegal content.

  • For maternal mortality progress has been even more elusive. Despite 15 years of the Safe Motherhood Initiative, overall levels of maternal mortality are generally thought to have remained unchanged, with the latest estimate of deaths standing at approximately 530,000 per year (WHO, UNICEF et al. 2003). While a handful of countries have indeed experienced remarkable drops in maternal mortality ratio (an indicator of the safety of childbirth and pregnancy), in the great majority of high mortality countries, there has been little change.

  • Concentration ratios are perhaps the most frequently used indicator of banking sector competitiveness, with a high share of assets controlled by a small number of banks typically interpreted as indicative of a low level of competition. Bank spreads (the difference between lending and deposit rates) are also often used as indicators of banking efficiency and competition, with higher spreads and margins interpreted as an indication of greater inefficiencies and lack of competition in the banking sector.

  • This study was aimed at investigating the physiological role of ferredoxin-glutamate synthases (EC 1.4.1.7), NADH-glutamate synthase (EC 1.4.1.14) and carbamoylphosphate synthetase (EC 6.3.5.5) in Arabidopsis. Pheno-typic analysis revealed a high level of photorespiratory ammonium, gluta-mine⁄glutamate and asparagine⁄aspartate in theGLU1mutant lacking the major ferredoxin-glutamate synthase, indicating that excess photorespiratory ammonium was detoxified into amino acids for transport out of the veins....
