Este libro trata de explicar como el estrés oxidativo y la disfunción mitocondrial representan pilares para el entendimiento de la Diabetes Mellitus. Las terapias dirigidas a reestablecer la homeostasis entre los mecanismos forma...

Le diethylamide de l'acide lysergique (LSD) est un puissant hallucinogène dérivé de l'ergot de seigle. L'analyse du LSD dans les fluides biologiques est complexe car le LSD est consommé à de faibles doses, est rapidement métabolisé avec une demi-vie courte et est un composé instable. Ainsi, une méthode analytique rapide et sensible a été développée et validée pour doser simultanément le LSD et ses métabolites (nor-LSD, iso-LSD, O-H-LSD) dans l...

Auslandsgeschäfte bringen viele Risiken mit sich - eins davon ist das Wechselkursrisiko. Beinahe täglich ...

Natural fibers traditionally have been used in form of short dispersed fibers in composite industry for non structural applications. In order to expand their market to semi or structural applications, there is huge gap in research studies. Fahimian in this book, with an extensive experimental research has identified the most important characteristics of natural fiber nonwovens that need to be measured in order to develop their application for ...

La Esclerosis Múltiple (EM) fue definida en su primera instancia como la representación de "una notable lesión en la médula espinal acompañada de atrofia" por Robert Carswell en 1983.

Using Vernier effect for photonics circuits including micro ring resonators can increase the free spectral range (FSR) which contributes to embed large channel count in DWDM system and increase the capacity of optical system. In this book, the Vernier effect in the Z domain with signal flow graph method and Mason's rule is used to derive the optical transfer functions (OTF) for Vernier type multiple stages vertically coupled micro ring resonat...

The study aims to view the English language teaching scenario at primary level in Himachal Pradesh in India. Majority population in the state reside in rural areas where, for education, children have access to government schools only. In such schools, learners are introduced to English language from Class One.

The purity and resolution are the two important factors of designing the DDFS, which need to be improved as much as possible. In this book different models of the DDFS are created, implemented and examined for different aspects to determine what would work best for an application. This book also focuses on the realization of fast FDM-TDM transmultiplexer algorithm used to construct a bank of digital filters. This book comprises of six chapters...

Over the last decades, persistent government budget deficits have led to a rapid accumulation of public debt in most developed countries. Part of this may be explained by the aggressive use of fiscal policy (excluding the stimulus measures employed to fight the most recent financial crisis). In fact, it turns out that fiscal policy is not conducted by benevolent governments, but rather by politically-motivated executives, who typically make us...

Research and policy on deforestation has often asserted it as "evil" because of the long term environmental implications for sustainable development evident in global warming, biodiversity loss and soil degradation. While this is true, it is undeniable forest degradation and deforestation has contributed tremendously to the development of households' livelihoods, income and employment and social amenities for the sustenance of forest fringe co...

The need for greater levels of energy efficiency has never been as clear as it is now. In the case of Chile, factors such as high energy consumption, high energy prices and growing concern for the environment and energy security have contributed to a growing awareness of the need for further developing energy efficiency. However, this awareness has mainly stayed at an strategic level and has not translated into concrete actions at the urban le...
