    Kurzfassung: This textbook provides an overview of applications of advanced nanomaterials, basic lab set up and requirements in for their synthesis, techniques and career scope of nanotechnology in industries and research. Pollution of air, water, soil is an ever increasing environmental problem attributed to increasing population, global industrialization and unplanned urbanization, has acquired alarming dimensions. It is the most dangerous and worst problem that puts the lives of people, animals, and plants on the earth in danger. An effective, efficient and sustainable approach for managing pollution related problems requires the utmost attention of the scientific community to tackle this menace for the society to lead a healthy and quality life. A number of techniques and books, literatures have been developed in recent years to treat environmental contaminants. However, most of these are not economically viable, environmentally benign and suffer due to cumbersome multi-step manipulations. The purpose of this textbook is to inform students about the application of functionalized nanoparticles as a new approach to supplement traditional treatment methods in cost and time effective manner. The simplistic means to assemble nanoparticles to the constituents of next generation technologies in environment cleanup and sensing are the main objectives of the book. The toxicological footprinting of released advanced functional nanomaterials in ecosystem will also be discussed in the book.

    Kurzfassung: This volume discusses the nutraceutical importance, production technologies, management and cultivation practices of underutilized vegetables, which can be described as those vegetable crops which are neither grown commercially on a large scale nor traded widely. While much of the crops addressed in the book are cultivated, traded and consumed at the local level, there are over 60 species of minor vegetables with high growth and yield potentials that are not cultivated to a large extent for greater populations. This work highlights the production technologies needed to grow these vegetables on a larger scale and under various adverse soil and climatic conditions, and their nutritional and medical benefits to assist with food security, health and poverty alleviation in rural areas. Production of underutilized vegetables is low, due to the unavailability of planting material, lack of awareness about the nutritional and medicinal importance among the farmers and inadequate information on the production techniques of these crops. In this context, there is an urgent need to take up a program on genetic resources exploration, management, utilization, and improvement of underutilized vegetable crops to ensure food and nutritional security. Readers will learn about these technologies and practices, while also learning about the unique properties and benefits of these underutilized vegetables. The book will be useful for academicians and researchers focusing on vegetable production and breeding, as well as farmers and sustainability scientists looking for underexplored sources of nutrition to benefit large rural populations.

    Notizen: Single crystals of n-Hg1−xCdxTe (x=0.18) were grown by the Bridgman technique. The bulk single crystals were irradiated with laser pulses of various energy densities. A pulsed laser (Nd:YAG) capable of producing 10-ns pulses of 0.53-μm wavelength (frequency doubled) with varying energy densities (2–50 mJ/cm2) was employed. dc conductivity and Hall coefficient measurements were made on the single crystal using the van der Pauw technique in the temperature range 77–300 K, for both as-grown and laser-irradiated samples. Also, transmission measurements of the samples were taken at room temperature. Both electrical and optical studies showed that laser irradiation introduces additional defects in mercury cadmium telluride (MCT), and its quality deteriorates instead of improving as observed in many other semiconductor materials. We found that laser irradiation increases free-carrier concentration and decreases the band gap of MCT.

Also the x-ray diffraction pattern and transmission measurements of the samples were taken at room temperature. Electrical studies shows that the p-mercury cadmium telluride after the laser irradiation becomes n type and optical results show that the free-carrier concentration after laser irradiation increases sharply so that there is negligibly small transmission. The x-ray studies show that single crystal p-type samples after laser irradiation undergo structural changes as well, introducing phases of CdTe, Hg, and Te in the lattice.

    Notizen: We report the anomalous Hall effect and nonuniformities introduced by aging in the bulk polycrystalline HgTe, which was grown in a predetermined profile, and measurements were taken in the temperature range of 82–350 K. It is found that anomalous behavior is caused by domain formation which is due to acceptor states and this domain formation effect gets diminished by annealing the sample in a mercury atmosphere.

    Notizen: Polycrystalline HgTe samples have been prepared by taking Hg and Te in stochiometeric compositions. The effect of annealing in mercury has also been studied. The effect of temperature on the electronic conduction mechanism and grain-boundary states has been observed through the measurement of Hall coefficient RH resistivity (ρ) and Hall mobility μH=(RH/ρ) on the polycrystalline HgTe in the temperature range ∼77–350 K. It is found that in electronic conduction in the low-temperature range, the conduction is dominated by the thermionic emission of electrons over the grain boundaries. At a critical temperature Tc where the barrier height Φb and, hence the width of the space-charge region near the grain boundaries tends to zero, a crossover from the barrier limited to the mobility limited resistivity occurs. RH is found to be thermally activated over the temperature range where the conduction mechanism is governed by the grain-boundary barrier. The experimental results are explained on the basis of a grain-boundary trapping model combined with two-phase model. It is found that the mobility and the grain size increased with annealing time. We achieved the carrier mobility of polycrystalline HgTe at 270 K to as much as 11 000 cm2/V s.

    Notizen: Abstract: Maintainability problems associated with traditional software systems are exacerbated in rule-based systems. The very nature of that approach — separation of control knowledge and data-driven execution — hampers maintenance. While there are widely accepted techniques for maintaining conventional software, the same is not true for rule-based systems. In most situations, both a knowledge engineer and a domain expert are necessary to update the rules of a rule-based system. This paper presents, first, an overview of the software engineering techniques and object-oriented methods used in maintaining rule-based systems. It then discusses alternate paradigms for expert system development. The benefits of using case-based reasoning (from the maintenance point of view) are illustrated through the implementation of a case-based scheduler. The main value of the scheduler is that its knowledge base can be modified by the expert without the assistance of a knowledge engineer. Since changes in application requirements can be given directly to the system by the expert, the effort of maintaining the knowledge base is greatly reduced.
