Ornamental fish resources. References. Subject index. The disparity between knowledge of the fisheries of the lakes and other lentic water bodies and that of the rivers is significantly palpable in India which obviously is the outcome of inchoate assiduity made on riverine ecology and fisheries research in the country. The paucity of extensive and empirical knowledge on the riverine ecology and fisheries has put the policy makers basin managers and other competent authorities at a disadvantage situation to redress the resultant malady in any developmental programmes culminating from these lotic bodies. The plight is significantly more conspicuous in Barak river system of India lying primarily within the geographical jurisdiction of Southern Assam and cursorily in Manipur and Mizoram States of N.E. India. Further the students and researchers of fishery science in general and those of Assam University and its affiliated colleges of NER in particular have since been deprived of an authentic prequel on the ecology and fisheries of Barak river system to meet the requisites of their study programme. The present treatise which encompasses an extensive profile on the ecology and fisheries of the Barak river system of India therefore will not only fulfill the need of these students in their academic pursuit along with other researchers in the field but will also make the policy makers and planners to materialize the fishery potentialities of the region on the fish fauna fluvial dynamics and ecology including the physico chemical conditions and potamoplankton communities of each lotic water system of the Barak drainages hitherto remained unexplored. Besides the capture fisheries of some principal rivers along with fishing gears and devices those are in vogue in the drainages have also been purported in the treatise. The endemic ornamental fish resources of the Barak river system a recent field of commercial importance have been incorporated in the book to expose their potentialities in global trade for the benefit of the entrepreneurs and aquarists of the region. 192 pp.

Zustand: Hervorragend. Zustand: Hervorragend | Seiten: 296 | Sprache: Englisch | Produktart: Bücher | This book highlights the overview of Spintronics, including What is Spintronics ?; Why Do We Need Spintronics ?; Comparative merit-demerit of Spintronics and Electronics ; Research Efforts put on Spintronics ; Quantum Mechanics of Spin; Dynamics of magnetic moments : Landau-Lifshitz-Gilbert Equation; Spin-Dependent Band Gap in Ferromagnetic Materials; Functionality of ¿Spin¿ in Spintronics; Different Branches of Spintronics etc. Some important notions on basic elements of Spintronics are discussed here, such as ¿ Spin Polarization, Spin Filter Effect, Spin Generation and Injection, Spin Accumulation, Different kinds of Spin Relaxation Phenomena, Spin Valve, Spin Extraction, Spin Hall Effect, Spin Seebeck Effect, Spin Current Measurement Mechanism, Magnetoresistance and its different kinds etc. Concept of Giant Magnetoresistance (GMR), different types of GMR, qualitative and quantitative explanation of GMR employing Resistor Network Theory are presented here. Tunnelling Magnetoresistance (TMR), Magnetic Junctions, Effect of various parameters on TMR, Measurement of spin relaxation length and time in the spacer layer are covered here. This book highlights the concept of Spin Transfer Torque (STT), STT in Ferromagnetic Layer Structures, STT driven Magnetization Dynamics, STT in Magnetic Multilayer Nanopillar etc. This book also sheds light on Magnetic Domain Wall (MDW) Motion, Ratchet Effect in MDW motion, MDW motion velocity measurements, Current-driven MDW motion, etc. The book deals with the emerging field of spintronics, i.e., Opto-spintronics. Special emphasis is given on ultrafast optical controlling of magnetic states of antiferromagnet, Spin-photon interaction, Faraday Effect, Inverse Faraday Effect and outline of different all-optical spintronic switching. One more promising branch i.e., Terahertz Spintronics is also covered. Principle of operation of spintronic terahertz emitter, choice of materials, terahertz writing of an antiferromagnetic magnetic memory device is discussed. Brief introduction of Semiconductor spintronics is presented that includes dilute magnetic semiconductor, feromagnetic semiconductor, spin polarized semiconductor devices, three terminal spintronic devices, Spin transistor, Spin-LED, and Spin-Laser. This book also emphasizes on several modern spintronics devices that includes GMR Read Head of Modern Hard Disk Drive, MRAM, Position Sensor, Biosensor, Magnetic Field sensor, Three Terminal Magnetic Memory Devices, Spin FET, Race Track Memory and Quantum Computing.
