Results are based on data collected from a survey of 300 household stratified into those with rain water harvesting structures and those without from which equal number of sample households were drawn randomly. Tobit model was used to estimate impacts of RWHT on household income and employment of hired laborers. The results indicate that among the variables used in the model, the variables that are significant in explaining the household income and employment generation are, availability of farmers` active labor force, household perception ,leadership status ,number of rain water harvesting structures owned, total land holding, and off-farm income activities availability. ····· 1036191560
für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Kenyan ecotourism industry has not fully exploited the opportunities presented by the internet to propagate its growth. The internet provides a new and important electronic commerce medium for tourism. The scale of the internet and its use to promote `disingenuous` ecotourism products may accelerate negative outcomes. However, the understanding of internet-based ecotourism developments - both delivery and outcomes - is limited. The overall purpose of this study is to assess the possible impacts of the internet technology on the Ecotourism industry in Kenya. The advancement of Internet technology worldwide has contributed to the enhancement of ecotourism principles. Despite much discussion devoted to defining ecotourism conceptually, knowledge regarding how ecotourism is actually developed through the Internet is still lacking. This book attempts to address these issues by exploring how ecotourism concept is enhanced through the Internet. ····· 1036191548

Among them, Genetic Algorithms (GA) is pre-dominating. In this paper I solve the problem with a new operator, Inver-over, for an evolutionary algorithm for the TSP. This operator outperforms all other `genetic` operators, whether unary or binary, which was first introduced by Guo Tao and Zbigniew Michalewicz. I also propose a new algorithm for solving TSP and also introduced it modified version. To get a comparative idea of the performance of these algorithms I solve same problems with the two algorithms. The performance analysis shows that my proposed algorithm produces relatively better solutions in the case of the tour length every time. But when we increase the cities it takes more time to solve than the Inver-Over operator for TSP. ····· 1036191458

Esta reforma considera indispensable que se tenga la información necesaria para tomar decisiones dentro de un sistema de mercado y de libre escogencia. Los problemas de asimetría en la relación de los actores que participan del sistema, permiten que la aplicación de las técnicas de agrupamiento borroso para la identificación de modelos borrosos se extienda al sector salud por tratarse de modelos locales no lineales para el control. En este trabajo se revisan las principales técnicas de agrupamiento para la identificación de los factores determinantes de asimetría de la información en la utilización del servicio médico en el Eje cafetero, incluyendo propuestas que permiten medir la asimetría de la información y clasificar dichos factores con técnicas borrosas. ····· 1036190857

Se identificaron bacterias patógenas de los géneros Aeromonas, Pseudomonas y Vibrio, además de diferentes géneros de la familia Enterobacteriaceae en diferentes órganos (branquias, intestino, riñón y lesiones en aletas) y en el agua de los estanques de cultivo de la especie. Algunas de estas bacterias pertenecen a la microbiota normal de los peces, mientras que la presencia de las enterobacterias se relacionada con las inadecuadas prácticas de manejo que llevan a cabo en dichas unidades de producción. Las variaciones con relación al número de UFC/g y UFC/mL estuvieron determinadas por los diferentes meses de muestreo donde se observó que la mayor cantidad de bacterias está dada en los meses de verano mientras que disminuye gradualmente en los meses de otoño. ····· 1036189879

It is also analyses the association of agency and sexual and reproductive health (SRH) young women. The study utilizes data from Youth in India: Situation and Needs, 2006-2007 survey. Bivariate and Multivariate techniques are used to understand the differentials, and factors associated with agency and Sexual and reproductive health. The Principal Component Analysis is used to compute the agency based on three indices namely decision making, freedom of movement, and self efficacy. The multinomial logistic regression is used to understand the factor associated with sexual and reproductive health knowledge. Higher Educated and economically better off women, more exposed to mass media, living in urban area have higher agency for both married and unmarried women.

The theory is that effortful thought and behavior benefit from additional stored metabolites, and that drinking alcohol temporarily reduces metabolites but later increases them. Participants attended a drinking, social event at night. The next morning, they completed an effortful task (a breath-blowing task requiring forceful exertion and persistence) before and after a mentally fatiguing task (controlling attention). Consuming more alcohol during the event predicted less fatigue on the effortful breath-blowing task, computed as the difference between performance on the task before and after the attention control task. Alcohol consumption might be one strategy for reducing later fatigue on effortful tasks. ····· 1036188303

It was revealed that a wide variation of lattice parameter of Al-rich solid solutions in presence of similar level of surface and strain energy played a pivotal role in the amorphous phase formation by mechanical alloying. None of the aforesaid alloys resulted in a completely amorphous structure and hence, an attempt was made to consolidate the mechanically alloyed fully amorphous powder of Al88Ni6Ti6 composition to produce bulk Al-rich nanocomposites having densities near to the theoretical density. Consolidation was carried out by spark plasma sintering, hot pressing and conventional pressure-less sintering methods. The microstructural features and mechanical properties were also investigated for the ultrasonically cast nanocomposites of Al reinforced with nano-sized Al2O3 (average size ~10 nm) particles.

Currently, interferon- and nucleosidic inhibitors of HBV reverse transcriptase, polymerase, lamivudine (3TC), adefovir and entecavir are the only drugs approved for the treatment of chronic HBV infection. However, interferon- -produces many side affects with partial efficacy less than 30% of the chronic carriers responding to treatment. In addition, about 50% of the patients who respond positively to interferon- treatments are known to suffer recurrence of the viremia after cessation of the treatment. In contrast, 3TC has more universal applicability and is able to reduce the viral load very rapidly. Complete and sustained suppression of viral replication remain the most important goal in the treatment of patient with chronic (HBV) infection. Nucleoside and Nucleotide analogues have greatly improved the disease outcome for these patients and have also prevented hepatic decompensation or the development of hepatocellular carcinoma. Therefore, there is need for drugs that directly inhibit HBV production. Most compounds explored so far are nucleoside analogs. ····· 1036187317

It further uncovers the other factors like school policy, working experience and personal learning experiences which also impact practice. It concludes by maintaining that teaching is an extremely complex activity and it is not always possible to link belief to practice. It is, nevertheless, vital to study the teachers beliefs as any professional development activities teachers engage in must consider the teachers beliefs as teachers always view new learning through their own belief lens.

This book highlights the utilization of vegetable oil, a sustainable resource, in the development of polyurethane resins in a systematically organised manner. In addition, various literatures regarding vegetable oil based polyurethane resins have been reviewed. The experimental part of the study describes our attempts to prepare, characterize and evaluate the properties of polyurethane resins based on Mesua ferrea L. seed oil. The book demonstrates that blending with commercial resins, formation of natural fibre decorated green composites and nanoclay incorporated nanocomposites lead to improvement in the performance characteristics of the prepared resins as coating materials. Biodegradability and cytotoxicity assessment of the blends and nanocomposites add value to the developed polyurethanes as novel biomaterials. The acceptable performance as binder for industrial stoving paints unmasks the industrial applicability of the prepared resin systems.
