Book excerpt: The history of spin in general, and of the nucleon spin structure in particular, has been full of surprises. For the past 25 years deep inelastic lepton scattering has been studied to determine the carriers of the nucleon spin. However, it was realized only recently that a full understanding of the nucleon spin will also require detailed information on the helicity structure in the resonance region, i.e. in the realm of nonperturbative QCD.This volume gives a status report on the spin structure in the nucleon resonance region, focusing on: new experimental results from SLAC and HERMES; a first glance at the JLab experiments to map out the spin structure functions at low and intermediate four-momentum transfers; the pioneering experiment at MAMI (Mainz) to determine the Gerasimov-Drell-Hearn sum rule for real photons; and recent theoretical concepts and investigations to describe the spin structure in the frameworks of higher twist expansion, phenomenological models and chiral perturbation theory.

Download or read book Plant Nutritional Genomics written by Martin R. Broadley and published by John Wiley & Sons. This book was released on 2009-02-05 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: A ‘textbook’ plant typically comprises about 85% waterand 13.5% carbohydrates. The remaining fraction contains at least14 mineral elements, without which plants would be unable tocomplete their life cycles. Understanding plant nutrition and applying this knowledge topractical use is important for several reasons. First, anunderstanding of plant nutrition allows fertilisers to be used morewisely. Second, the nutritional composition of crops must betailored to meet the health of humans and livestock. Third, manyregions of the world are currently unsuitable for crop production,and an understanding of plant nutrition can be used to developstrategies either for the remediation of this land or for thecultivation of novel crops. That application of knowledge of plant nutrition can be achievedthrough genotypic or agronomic approaches. Genotypic approaches,based on crop selection and / or breeding (conventional or GM),have recently begun to benefit from technological advances,including the completion of plant genome sequencing projects. Thisbook provides an overview of how plant nutritional genomics,defined as the interaction between a plant's genome and itsnutritional characteristics, has developed in the light ofthese technological advances, and how this new knowledge mightusefully be applied. This is a book for researchers and professionals in plantmolecular genetics, biochemistry and physiology, in both theacademic and industrial sectors.

This book was released on 2006-04-11 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: According to many textbooks, carbohydrates are the photosynthesis and mitochondrial respiration fluctuate in a circadian manner in almost every unique final products of plant photosynthesis. However, the photoautotrophic production of organic organism studied. In addition, external triggers and environmental influences necessitate precise and nitrogenous compounds may be just as old, in appropriate re-adjustment of relative flux rates, to evolutionary terms, as carbohydrate synthesis. In the algae and plants of today, the light-driven assimilation prevent excessive swings in energy/resource provision of nitrogen remains a key function, operating and use. This requires integrated control of the alongside and intermeshing with photosynthesis and expression and activity of numerous key enzymes in respiration. Photosynthetic production of reduced photosynthetic and respiratory pathways, in order to carbon and its reoxidation in respiration are necessary co-ordinate carbon partioning and nitrogen assim- ation. to produce both the energy and the carbon skeletons required for the incorporation of inorganic nitrogen This volume has two principal aims. The first is to into amino acids. Conversely, nitrogen assimilation provide a comprehensive account of the very latest developments in our understanding of how green is required to sustain the output of organic carbon cells reductively incorporate nitrate and ammonium and nitrogen. Together, the sugars and amino acids into the organic compounds required for growth.

Download or read book Nitrogen Acquisition and Assimilation in Higher Plants written by Sara Amancio and published by Springer Science & Business Media. This book was released on 2007-09-29 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen is an essential element for plant growth. During the green revolution nitrogenfertilisation was responsible for spectacular yield increases. At present yield is balanced with commitments towards the environment and sustainable agriculture. For agro-biotechnology comprehensive knowledge of plant functioning is needed. Yield improvement and accumulation of essential nitrogen compounds is relying on selection and gene technologies. Research on the uptake, acquisition and assimilation of nitrogen, as well as the synthesis and storage of reserve and defence N-compounds, therefore, is essential. The third volume in the Plant Ecophysiology series integrates functional and molecular physiology with ecophysiological and sustainable agricultural approaches to get a better understanding of the regulation and the impact of environmental and stress signals on nitrogen acquisition and assimilation. The book is of interest for advanced students and junior researchers and supplies comprehensive information for scientists working in the field of nitrogen metabolism and readers interested in sustainable development.

Download or read book NSTAR 2001 written by Lothar Tiator and published by World Scientific. This book was released on 2001 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of N∗s can provide us with critical insights into the nature of QCD in the confinement domain. The keys to progress in this domain are the identification of its important degrees of freedom and the effective forces between them. The nucleon is the simplest system in which the nonabelian character of QCD is manifest. There are Nc quarks in a baryon because there are Nc colors, and as a consequence Gell-Mann and Zweig were forced to introduce the quarks in order to describe the octet and decuplet baryons.This volume gives a status report on the recent experimental and theoretical results in the field of nucleon resonance physics. A wealth of new high precision data was presented from facilities around the world, such as BES, BNL, ELSA, GRAAL, JLab, MAMI, MIT/Bates, SPring8, and Yerevan. Particular emphasis was laid on polarization degrees of freedom and large acceptance detectors as precision tools for studying small but important transition amplitudes, and the helicity (spin) structure of the nucleon. There were new results describing the nucleon resonance structure on the basis of quantum chromodynamics, either directly in terms of quarks and gluons by means of lattice gauge theory, or in terms of hadrons in the framework of chiral field theories. A status report on duality showed the surprising connections between the physics of the low energy nucleon resonance region and the realm of quark structure functions in deep inelastic scattering. Finally, this volume contains a summary report of the BRAG workshop, devoted to the analysis of baryon resonances.
Download or read book The Spin Structure of the Proton written by Steven D. Bass and published by World Scientific. This book was released on 2008 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the main challenges in nuclear and particle physics in the last 20 years has been to understand how the proton's spin is built up from its quark and gluon constituents. Quark models generally predict that about 60% of the proton's spin should be carried by the spin of the quarks inside, whereas high energy scattering experiments have shown that the quark spin contribution is small - only about 30%. This result has been the underlying motivation for about 1000 theoretical papers and a global program of dedicated spin experiments at BNL, CERN, DESY and Jefferson Laboratory to map the individual quark and gluon angular momentum contributions to the proton's spin, which are now yielding exciting results. This book gives an overview of the present status of the field: what is new in the data and what can be expected in the next few years. The emphasis is on the main physical ideas and the interpretation of spin data. The interface between QCD spin physics and the famous axial U(1) problem of QCD (eta and etaprime meson physics) is also highlighted. Book jacket.
