Hardcover. Zustand: New. Science and advanced technology together with conscious application can bring magnificent revolution in any sector, including sunrise aquaculture sector as well. Keeping this in mind, the current book focuses on the recent technical revolution in several sub-sectors of aquaculture. This book mainly emphasizes the potential of modern biotechnological tools for analyzing the impact of various molecular biology approaches in fisheries and aquaculture. Apart from molecular biology and bioinformatics, aptful logical sections on the state of art popular fish farming techniques including Biofloc Technology (BFT) and Re-circulatory Aquaculture System (RAS) have been discussed in detail. A few chapters will provide thorough insights on various fish disease diagnosis techniques and therapeutic measures. Chapters dealing with environmentally friendly alternative drugs, and herbal medicines have also been incorporated. Pollution control and environmental protection are increasingly top priorities in addition to technological advancement. In this direction a single chapter will provide insight into the role of aquatic algae in controlling pesticide pollution. In the space of around 350 pages, encompassing 16 chapters have been accommodated: Recent advancement of biotechnology and molecular biology tools in fisheries and aquaculture; Modern Biotechnological Approaches of Fish Based Biomaterials; Blue Biotech Revolution: Next-Gene Sequencing in Fisheries and Aquaculture; Future Prospective of eDNA in Aquaculture and Method, its Challenge to Small Farmers; Insights into the Biofloc Fish Farming Status of India; Application of Medicinal Plant in Fish Feed and its Challenges; Application of Recent and Trend Tools in Fish Disease Diagnosis; Fish Therapeutics and Its Limitations; Application of Herbs in Fish Feed and its Importance and Challenges; Application of Aquatic Algae for Indication and Controlling of Pesticide Pollution; Recent Trend in Fish Farming: An Overview; Zero Tillage Fish Farming and its Importance; Analysing the Therapeutic Impact of Marine Organisms Derived from Osteoporosis Using Machine Learning; Carbon and Nitrogen Ratio in Shrimp Aquaculture Systems; Re-circulatory Aquaculture System (RAS) and its Challenges to Fish Farmers; Histological Alterations in Gill, Kidney and Liver of Fish as a Diagnostic Tool for Ecotoxicological Research.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Master's Thesis from the year 2010 in the subject Mathematics - Applied Mathematics, grade: 85%, Priyadarshini College of Engineering, Nagpur, course: M-TECH., language: English, abstract: In this study, a foundation and solution technique using Genetic Algorithm (GA) for design optimization of worm gear mechanism is presented for the minimization of power-loss of worm gear mechanism with respect to specified set of constraints.Number of gear tooth and helix (thread) angle of worm are used as design variables and linear pressure, bending strength of tooth and deformation of worm are set as constraints.The GA in Non-Traditional method is useful and applicable for optimization of mechanical component design. The GA is an efficient search method which is inspired from natural genetics selection process to explore a given search space.In this work, GA is applied to minimize the power loss of worm gear which is subjected to constraints linear pressure, bending strength of tooth and deformation of worm.Up to now, many numerical optimization algorithms such as GA, Simulated Annealing, Ant-Colony Optimization, Neural Network have been developed and used for design optimization of engineering problems to find optimum design. Solving engineering problems can be complex and a time consuming process when there are large numbers of design variables and constraints. Hence, there is a need for more efficient and reliable algorithms that solve such problems. The improvement of faster computer has given chance for more robust and efficient optimization methods. Genetic algorithm is one of these methods. The genetic algorithm is a search technique based on the idea of natural selection and genetics.

Hardcover. Zustand: New. 1st Edition. Contents: Preface. 1. Introduction. 2. Enumeration of pteridophytes. 3. Enumeration of gymnosperms. 5. Enumeration of angiosperms. Photographs. References. Index. From the preface: Nagaland, one of the smallest states of India with an area of 16,579 sq.km is a mountainous state in northeast India which shares its borders with Assam in the west, Arunachal Pradesh and part of Assam in the north, Manipur in the south and Myanmar in the east. Owing to its varied topography from the foothills with tropical climate to the alpine zone of Mt. Saramati (3841 m) coupled with high rainfall, the state harbours diverse and rich vegetation. The forests cover of the state is 12,966 km2, which is 78.21% of the state's geographical area (FSI: 2015). Botanical exploration of the state dates back to 1837 by British botanists W. Griffith and subsequently by many other botanists and is being continued till today. However, there is no detailed information on the flora of Nagaland as on date as all these contributions by various botanists are scattered and fragmentary, concentrated either on one group, protected areas, district etc., except for pteridophytes and Orchidaceae. Recently Botanical Survey of India, Eastern Regional Centre, Shillong has initiated the work on Flora of Nagaland and is working extensively to survey major parts of all the 11 districts of the state, which will take few more years to finalize the complete flora. Hence, an attempt is made to list all the plants (Pteridophytes, Angiospersm and Gymnosperms) from published literatures, Assam Herbarium and Nagaland University Herbarium with updated nomenclatural changes at one place in the form of a checklist. This checklist on Flora of Nagaland is meant to provide a preliminary source of information to Botanists and is in no means a comprehensive and ultimate flora of the state.

This book provides a complete and comprehensive account of the orchid flora of Assam. Based on extensive field survey and herbarium study, the authors have recorded 477 taxa (469 species, 3 subspecies and 5 varieties) belonging to 107 genera from the ambit of the political boundary of Assam. The systematic account of this guide is prepared according to the latest system of orchid classification. Lucid taxonomic keys and descriptions at various hierarchy levels (e.g. Subfamily > Tribe > Genera > Species > variety) have been provided for easy and precise identification of taxon by avoiding confusion. For each species, taxonomic citation followed by a detailed description, phenology, habitat, regional and global distributional data and regional conservation status etc. has been provided. About 350 taxa are illustrated with 700 coloured photographs and 77 Lankester Composite Dissection Plates, specially prepared from the photographs of dissected floral parts. Besides, 150 species are also illustrated with conventional black and white line drawings. The introductory chapter of this guide deals with the overall morphology of orchids and their growth habits. A general account on Assam is provided to cover physiography, climate, vegetation, and forest types in Assam. Individual chapters are also dedicated to the history of botanical explorations in Assam, various threats to the orchid flora of Assam, their conservation, phytogeography and endemism.
