  • The strong recovery in net private capital flows to emerging markets that began in 2003 has continued this year. Although a moderation in the pace of flows is anticipated in the next several quarters, the overall level envisaged for 2006 remains relatively elevated. Downside risks have increased, however, in the face of rising concerns and unease about a potentially less hospitable global economic environment going forward.

  • The mountainous area occupies three fourth of the total area of Binh Dinh Province. The potential of landuse is very large. However, under the influence of irrational exploitation and natural disasters in the past, the land resource has declined, thus leading to the decline of forest resource. Furthermore, the increase of unused land and bare hills along with the decrease in the cultivated area seriously influenced on the ecological environment as well as the socio-economic development.

  • I present the investigation involving two extensions of the cellular automaton based NagelSchreckenberg model, the Velocity-Dependent-Randomisation (VDR) model, and the two-lane model for symmetric and asymmetric lane changing rule sets. The study of the VDR model outlines a potential method in extending the lifetime of a metastable state and consequently postponing an inevitable traffic jam by orders of magnitude. The two lane model produces a so called "critical" and "sub-critical" flow which combined cause the collapse of flow at a critical density.

  • Constructed wetlands are known widely by their characteristic properties like utilization of natural processes, simple and easy of construction, operation and maintain as well. The constructed subsurface flow wetland is designed as a tank with an impervious boundary to prevent seepage and contain a suitable porous media in which emergent plants grow. The water remains below the surface of the gravel/stone/rock media. Soil in constructed subsurface flow wetland absorbs and stores organic matter several years.

  • Within the overall transport process, attenuation processes may cause movement of the chemical to differ from that of the bulk flowing groundwater, for example dispersion, sorption and chemical or biological degradation of the chemical. Such attenuation processes potentially act to mitigate the impact of chemicals and are a function of both the specific chemical and geologic domain. Indeed, attenuation may vary significantly between individual chemicals and within different geological settings.

  • Poverty reduction has two fundamental requirements: enabling the poor and marginal groups to participate in decisionmaking about their own development, and giving them access to capital, technology, credit, and land, especially in the case of the rural poor. Programs to deliver these basics must be designed with accuracy and sophistication within a frame- work of macroeconomic social policies whose main objective is poverty reduction.

  • Coincidentally, in the case of the aforementioned regulations a STAG (STeam And Gas) cycle qualification is/was to provide about 6% of its steam generation to process. At this operating condition, the overall performance approaches that of a conventional STAG power generation cycle. Later in this paper, tables are provided that define GE’s gas turbine and gas engine product characteristics, which in turn illustrate the wide application range and flexibility of these products to support cogeneration applications.

  • During development of an undivided flow battery based on the Pb(II)/Pb and PbO2 /Pb(II) couples in aqueous methanesulfonic acid, it was noted that battery performance might be improved by additives that (i) decrease the roughness of the lead deposit at the negative electrode and (ii) enhance the kinetics of the Pb(II)/PbO2 couple at the positive electrode. This paper reports the study of sodium ligninsulfonate and polyethylene glycol as potential levelling agents for lead and of three inorganic ions as possible catalysts for the Pb(II)/PbO2 couple. ...

  • THE WILEY BICENTENNIAL-KNOWLEDGE FOR GENERATIONS G a c h generation has its unique needs and aspirations. When Charles Wiley first opened his small printing shop in lower Manhattan in 1807, it was a generation of boundless potential searching for an identity. And we were there, helping to define a new American literary tradition. Over half a century later, in the midst of the Second Industrial Revolution, it was a generation focused on building the future. Once again, we were there, supplying the critical scientific, technical, and engineering knowledge that helped frame the world....

  • Whenever new communications and media platforms have been introduced, their innovation and application was met with scepticism, fear or outright banning by the ruling parties and authorities who feared the unknown medium, and its capacity to oust them from power. Therefore, new (mass) media historically face suspicion, and are liable to excessive regulation as they spark fear of potential detrimental effects on society, security and political power structures.

  • A younger investor, less concerned about these issues, may not be sat- isfied with the lower expected return that inflation hedging implies. It follows from a model with additional hedge portfolios that an OE portfolio for performance evaluation should have the same exposures as the managed portfolio to be evaluated, not just with respect to the overall market, but also with respect to the other relevant risk factors. A related asset pricing model is the Arbitrage Pricing model of Ross (APT, 1976), which allows for several risk factors to determine assets’ expected returns.

  • The outputs of an ARIES session have numerous practical uses for conservation and economic development planning. Notably, they can show which regions are critical to maintaining the supply and flows of particular benefits for specific beneficiary groups. By prioritizing conservation and restoration activities around sources and sinks for particular services, benefit flows may be maintained or increased. Similarly, focusing development or extractive resource use outside these regions can prevent degradation of benefit flows.
