  • Sediment Transport in Aquatic Environments is a book which covers a wide range of topics. The effective management of many aquatic environments, requires a detailed understanding of sediment dynamics. This has both environmental and economic implications, especially where there is any anthropogenic involvement. Numerical models are often the tool used for predicting the transport and fate of sediment movement in these situations, as they can estimate the various spatial and temporal fluxes.

  • Effective cost management can be accessed from administrative expense ratio. Negative relationship between administrative expense ratio and mutual growth are confirmed as expected. This implies AMCs with higher effective cost management have higher growth. Positive relationship between funds growth and management fees is as expected but not statistically significant. Negative relationship between size of the AMCs and mutual fund growth is found. Effect from size is different from what the model expects.

  • Paradoxically, skin is both a primary barrier to systemic absorption of topically exposed chemicals and a portal to systemic delivery of transdermal medicaments. Knowledge of the factors that determine both extent and rate of chemical flux across the skin is an important component of both toxicology and pharmacology studies. The aim of this book is to provide current approaches and techniques by which dermal absorption may be quantitated utilizing end points relative to these two disciplines.

  • Emission inventories play a dual role in global air pollution issues. Firstly, they can be used directly to establish the more important source categories, to identify trends in emissions and to examine the impact of different policy approaches. Secondly, emission inventories are used to drive atmospheric models applied to assess the environmental consequences of changing trace gas emissions and concentrations and to provide advice to policy makers. This second role contributes to the atmospheric modelling community being an important user of emission inventories.

  • A numerical model using the 1D shallow water equations was developed for the simulation of long wave propagation and runup. The developed model is based on the Finite Volume Method (FVM) with an application of Godunov - type scheme of second order of accuracy. The model uses the HLL approximate Riemann solver for the determination of numerical fluxes at cell interfaces. The model was applied to the simulation of long wave propagation and runup on a plane beach and simulated results were compared with the published experimental data. The comparison shows that the present model has a power...

  • They find that the elasticity of CO2 emissions and energy are close to unity (i.e., a 1% increase in population leads to an approximately 1% increase in CO2 emissions). They do not estimate how these elasticities may vary with population levels. All of these results are based on cross-sectional data for 1 year only. Finally, Shi (2003), again in the context of the IPAT model, uses a panel of cross-sectional and time series data. Shi finds population elas- ticities for CO2 of between 1.41 and 1.

  • The purpose of this thesis is to delineate important issues that sociable designers should consider when they develop structures intended to encourage social interaction. In doing so, i address both theoretical and computational contributions to this area of research. While i sketch a conceptual model for addressing these issues, the prototypes that are discussed reveal the challenges that we, as researchers and designers, must face. Rather than providing solutions, they expose the weaknesses in this area of research and suggest paths for future research.

  • Heraclitus, the ancient Greek sage (c. 536-470 B.C.) declared that everything is in flux. Everything changes, and no one can step twice in the same waters of a river. What seemed true to Heraclitus is even more true in our times. Old certainties give way to uncertainty. Old traditions no longer sustain human behavior. This is true in the personal as well as in the professional realms. Professional monodoxy has given way to a plethora of theories and interventive strategies (Corsini, 1981).
