Lake Abiyata is a closed, highly alkaline lake located in the Main Ethiopian Rift where extractable soda ash for industrial production is available.This book mainly analyses the major environmental impacts of soda ash extraction in the last two decades of the Main Ethiopian Rift Lakes, particularly Lake Abijata.The long-term mean monthly lake levels of Ziway and Langano Lakes show fluctuations about the average values whereas Lake Abijata has ...

This work presents the case of the American economy as a repudiation of the two-stage theory of capitalist development advanced by theorists like Hilferding, Steindl and Baran and Sweezy. Various cases from the American economy are presented to contradict the argument that with the emergence oflarge-scale industry competition among capitals is eliminated or highly restricted. The experience of the American automobile industry confirms Marx's a...

Die Entscheidung in ein neues Informationssystem zu investieren, bedeutet nicht nur es zu kaufen! Es bedeutet vielmehr dieses System im Sinne der Unternehmensstruktur zu beschreiben, zu planen und abschließend auszuwählen. Eine Investition in ein neues Informationssystem ohne entsprechende Analyse der Soll - Anforderungen, der vorherrschenden Stärken und Schwächen und eines abschließenden Anbietervergleichs, wäre eine geplante Fehlinvestition!...

The transnational advocacy campaign against the construction of a second oil-transporting pipeline, the Oleoducto de Crudo Pesado, in Ecuador had no discernible impact on the decision of that state to endorse the pipeline project and only a weak influence on the crafting of related social and environmental policies. This outcome is at odds with the theoretical formulation advanced by Keck and Sikkink which holds that certain transnational advo...

The scope of this thesis was to develop a comprehensive model system of the genus Daphnia, a key organism in the pelagic food web of lakes and reservoirs and a widely used model organism in experimental and theoretical ecology. Although its central role in applied and basic research in aquatic ecology is obvious, there are still fundamental problems in modelling the observed dynamics of Daphnia (for details see chapter 2). Therefore, a basic m...

Computer simulation is one of the most important methods for analyzing telecommunication networks. Simulations in this field often require parallel streams of random numbers. Many simulation tools used by the scientific community in this area are not aware of the sensible task of generating uncorrelated random numbers. Their built-in generators are old and weak, thus producing severely wrong simulation results in certain scenarios. This book c...

We analyze simulation relations as heuristics for the simplification of omega-automata, i.e., of finite automata working on infinite strings. Our focus is on alternating omega-automata, especially automata resulting from LTL formulas, as is important in model checking. We introduce direct, delayed, and fair simulation for alternating Büchi automata (ABA), and simulation quotient constructions for ABA. Our simulations are compatible with the st...

The Community Initiative LEADER provides funding for rural areas and local actors and seeks to establish links between actions for the development of the rural economy. It aims to implement integrated, effective and sustainable strategies for rural development. This dissertation will elaborate a concept for the ?Broads and Rivers? Local Action Group (LAG) in Norfolk, England, in order to be prepared for the next financial perspective of the Eu...

Computer haben die menschliche Gesellschaft so nachhaltig verändert wie vielleicht das Rad vor ihnen. Diese technischen Geräte sind aus dem Alltag der zivilisierten Welt nicht mehr wegzudenken. Doch werden die breit gefächerten kognitiven Kanäle des Menschen bei der Benutzung dieser Geräte auch tatsächlich optimal genutzt? Der Mensch nimmt einen Großteil seines Umfelds über das visuelle Kanal wahr. Die Evolution hat diese kognitive Fähigkeit p...

Among immigrant communities in the United States, the shift from heritage language dominance to bilingualism to English monolingualism is a well established phenomenon. While a number of influences outside the home are known to play an important role in this process, factors inside the home are inarguably influential but largely mysterious. This book sheds light on this area through an examination of language policy, ideology, and shif...

Alberta, one of the largest energy producers in the world, is responsible for almost one-third of the total Canadian anthropogenic greenhouse gas (GHG) emissions. These GHG emissions may be contributing to the current climate change and are caused mainly by the fossil fuel combustion and fugitive sources. The Alberta Ministry of Environment has set up a provincial climate change strategy to reduce GHG emissions. To assess this strategy, this b...

The central element of O. Wilde's novel, Dorian's portrait, has itself received little critical attention, although the concept of the body as the 'canvas of conduct' implicit in its magic is culturally problematic: it presupposes a profound moral framework and a, potentially discriminating, corporal symbolism. Moreover, the motif of the fading portrait characteristically binds eccentric personal development to a segregative notion of 'declin...

This thesis presents algorithm and architecture for simultaneous diagonalization of matrices. As an example, a subspace-based speech enhancement problem is considered, where in the covariance matrices of the speech and noise are diagonalized simultaneously. In order to compare the system performance of the proposed algorithm, objective measurements of speech enhancement is shown in terms of the signal to noise ratio and mean bark spectral dist...

Wrinkling of thin membranes due to different in- plane loadings and boundary conditions has drawn attention of researchers in structural engineering since the development of thin webs for early aircraft structures. More recently, pre-stressed lightweight membrane structures have been proposed for future space missions, for example solar sails, the next generation space telescope sunshield and space-based radar systems. These structures are of...

This is the fourth book which I have put forth with utmost hard work and in depth coverage. This book has been ideated to help the students understand the basic concepts of Molecular Biology and Bio- techniques. This book is written mostly from the viewpoint of the basic scientist who works at the cellular and molecular level. As molecular biology is one of the fore front subjects in research and development these days, it has become almost ne...

What is the most effective way of teaching a language?" There have been debates and research studies on this question throughout the history of language teaching. Through that time, new approaches and methods have been tried and applied as alternatives to the previous ones. From the 1950s to the 1980s, the rise and fall of a number of approaches and methods in language teaching gave the period the name "The Methods Era" and also led to...

Education does not exist in a vacuum. It is anchored in a changing society, a society that is characterised by an ever-increasing use of new media, and of information and communications technology (ICT) in particular. Not many people in the western world remain unfamiliar with mobile phones, the Web, and Internet related interaction. Evidently, education cannot be left untouched, and the increasing efforts to implement the use of computer t...

Où en est la Chine d'aujourd'hui ? Quels problèmes rencontre-t-elle depuis 1978 quand la réforme économique est mise en oeuvre d'abord dans les milieux ruraux ? Derrière la croissance remarquable de son économie pendant plus de vingt ans, il est important d'explorer les rapports Etat-Paysannerie par problèmes du San Nong, une abréviation en chinois de la paysannerie (Nongmin), la campagne (Nongcun) et l'agriculture (Nongye), et par les pratiqu...

Hyperspectral imaging is a powerful technique and has been used in a large number of applications. However, it generates massively large image data sets. Access and transport of these data sets will stress existing processing, storage and transmission capabilities. A new embedded, block-based, wavelet transform coding algorithm of low complexity is developed for hyperspectral image compression: Three-Dimensional Set Partitioned Embedded bloCK...
