From the preface: "Chandaka-Dampara Wildlife Sanctuary, situated in Khurda and Cuttack districts of Orissa, consists of semi-evergreen forest, dry mixed deciduous forest and bamboo brakes. Elephants form the most important vertebrate of these forests. Chandaka-Dampara Wildlife Sanctuary has an area of 193.39 sq km with a very rich biodiversity, and especially along with its elephant population, was elevated to a Wildlife Sanctuary in 1983. However, due to its proximity (25 km) to the capital city of Bhubaneshwar and the increasing human population, the anthropogenic pressure on the forest has increased considerably during recent years. A stringent conservation measure is needed for the protection of the biodiversity of this Wildlife Sanctuary. "The Zoological Survey of India has so far published the faunal inventory of two conservation areas of Orissa viz. Simlipal Tiger Reserve and Chilka Lake. Studies on the faunal diversity of Chandaka-Dampara Wildlife Sanctuary has been negligible except for Tiwari et al. (1998) on mammals of the Sanctuary. Hence, to conserve the rich faunal diversity of the Sanctuary, an extensive study was undertaken between 1995 and 1998, and the present volume covers a comprehensive account of the vertebrate fauna of the said Sanctuary. This document is therefore, the first ever consolidated account of the vertebrates occurring in the Sanctuary. The present volume includes a systematic account of 37 species of mammals, 167 species of birds, 33 species of reptiles, 13 species of amphibians and 28 species of fishes. Almost all groups are represented by coloured photographs for most of the species recorded in the respective chapters.".…

Key to the families of fern and fern allies. The present title Flora of Barak Valley, Assam with their Economic Utility is a pioneer floristic work on the valley particularly on Herbaceous Flora. The present book provides the historical and Geographical features vegetation pattern, materials and methods along with detail taxonomic treatments of the collected species. the unique features lies in providing economic utility of the collected species based on field data and comparison with the established report of utility. The book also exhibits analytical drawings and field photographs for a vast majority of collected herbaceous flora. In the present title a total of 596 species belonging to 142 families of Herbaceous flora have been enumerated out of which 83 species having 34 families represent fern and fern allies and rest 513 species with 108 families belong to angiosperms. The book made records of some very interesting species as regards to their diverse economic and ethno-botanical features. There are the reports of some new, rare and threatened species in the present title.…

Taschenbuch. Zustand: Neu. Neuware - Reduction of optical losses in both mono and multicrystalline silicon solar cells by surface texturing is one of the important issues of modern silicon photovoltaics. Texturing of the front surface of silicon solar cells has been modeled and analysed with reference to the reduction in reflection co-efficient and increase in optical trapping. Significant enhancement in open circuit voltage and short circuit current has been achieved through such texturing of the front surface of mono-silicon solar cells. A proper optimisation of texture angle appears to be important for the best performance of the solar cells. An alternative way of reducing the surface reflection and enhancement of the cell parameters is to produce to passive front surface porous silicon layer. An analysis of the characteristics of a porous silicon layer shows that the morphology of the layer is an important design parameter. To realise the structures in practice, several methods are available, but many of this method are either not cost effective or commercially non available. In order to achieve good uniformity of pyramidal textured structure of the silicon surface, a mixture of NaOH/KOH and isopropyl alcohol (IPA) is generally used for texturization of mono crystalline solar cells. However, due to high cost of IPA, there is always search for alternative source. This source should not only be cost effective but should also result in reduced interfacial energy between silicon and ionised electrolyte chemical solution to achieve sufficient wet-ability for the silicon surface in order to enhance pyramid nucleation. Different novel texturization techniques for monocrystalline silicon are descried in this chapter including solar cells performance. For multicrystalline silicon (mc-Si) solar cells, the standard alkaline solution of NaOH/KOH does not produced textured surface of good quality so as to give satisfactory open circuit voltage and efficiency. This is because of grain boundary delineation with step formed between successive grains of different orientations. Different novel texturization techniques for multicrystalline silicon are also included in this book including solar cells performance.…
