This book was released on 1991 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: Com o estudo da variabilidade genetica em 12 cultivares de soja com resposta conhecida ao dano mecanico, buscou-se desenvolver uma metodologia capaz de selecionar genotipos de soja com semente resistente ao dano mecanico, a qual e de fundamental importancia para a producao de sementes e/ou graos destinados a industrializacao para consumo humano. Duas metodologias para provocar o dano mecanico foram utilizadas. O 'teste de queda' livre das sementes, atraves de um tubo de PVC com altura de 180 cm sobre um prato de aco inclinado a 12 graus, e o 'teste do pendulo', que baseia-se na queda livre de um pendulo metalico sobre sementes individualizadas em alveolos de um prato metalico. O 'teste de queda' livre nao possibilitou a selecao genotipos em classes de resis-tencia ao dano mecanico. O 'teste do pendulo' permitiu a identificacao dos padroes de resistencia e suscetibilidade ocorrentes nos 12 cultivares de soja em estudo, sendo possivel agrupa-los em classes de resistencia. Em estudos preliminares identificou-se a altura ideal de queda deste pendulo (13cm). Posteriormente, foi avaliado o efeito de diferentes teores de umidades na semente (13%, 11% e 9%) na suscetibilidade ao dano mecanico atraves dos testes de tetrazolio e hipoclorito de sodio. Atraves dos resultados, observou-se que o aumento do teor de umidade na semente proporcionou um aumento na resistencia das sementes ao dano mecanico, sendo observado para cada teor de umidade altos valores de correlacao entre as duas metodologias de avaliacao. Os 12 ...

This book was released on 2003 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Este trabalho teve como objetivo avaliar a qualidade fisiológica de sementes de dezesseis genótipos de soja, armazenadas em condições adversas, visando, recomendálos em novos cruzamentos e em armazenamentos longos. Foi desenvolvido um experimento no laboratório de análise de sementes. No núcleo Experimental de Ciências Agrárias-NCA, da Universidade Federal de Mato Grosso do Sul, em Dourados, MS, no ano agrícola de 2000/2001. Uitilizou-se o delineamento experimental inteiramente causalizado, com quatro repetições, em esquema fatorial 16 x 2 x 3, sendo dezesseis genótipos de soja, armazenados em dois ambientes: ambiente 1 (armazenagem em sala laboratorial, com variação de temperatura de 18,2 a 28,8 o.C e umidade relativa de 52% a 76%) e ambiente 2 (armazenagem em câmara laboratorial, com controle de temperatura média de 16 o.C e umidade relativa média de 80%), avaliadas em três épocas (zero, quatro e oito meses de armazenamento), sendo que cada genótipo correspondeu a um tratamento. Após o armazenamento dos genótipos foram realizados os seguintes testes: grau de unidade, teste padrão de germinação, emergência a campo, índice de velocidade de emergência e comprimento de plântulas e envelhecimento acelerado. Conclui-se que os genótipos BRS-134, Coodetec-201, Coodetec-204, Coodetec-209, Msoy-7101 e Msoy-7701 foram os mais resistentes às condições adversas de armazenamento, quando avaliados pelos testes padrão de germinação, emergência a campo e envelhecimento acelerado. Os genótipos deterioram mais rapidamente em ambientes com temperaturas e umidades relativas variáveis, do que em ambientes com temperaturas e umidades relativas variáveis, do que em ambientes com temperaturas e umidades relativas variáveis, do que em ambientes com temperatura e unidades relativas controladas, mesmo quando armazenadas com grau de umidade alto. Na média dos genótipos, as sementes armazenadas no ambiente 2 apresentam menor deterioração, a partir dos 120dias de armazenamento. Sementes com alto grau de umidade devem ser armazenados em ambiente com baixa temperatura.

Available in PDF, EPUB and Kindle. Book excerpt: This book reports on developments in Proximal Soil Sensing (PSS) and high resolution digital soil mapping. PSS has become a multidisciplinary area of study that aims to develop field-based techniques for collecting information on the soil from close by, or within, the soil. Amongst others, PSS involves the use of optical, geophysical, electrochemical, mathematical and statistical methods. This volume, suitable for undergraduate course material and postgraduate research, brings together ideas and examples from those developing and using proximal sensors and high resolution digital soil maps for applications such as precision agriculture, soil contamination, archaeology, peri-urban design and high land-value applications, where there is a particular need for high spatial resolution information. The book in particular covers soil sensor sampling, proximal soil sensor development and use, sensor calibrations, prediction methods for large data sets, applications of proximal soil sensing, and high-resolution digital soil mapping. Key themes: soil sensor sampling – soil sensor calibrations – spatial prediction methods – reflectance spectroscopy – electromagnetic induction and electrical resistivity – radar and gamma radiometrics – multi-sensor platforms – high resolution digital soil mapping - applications Raphael A.

Book Synopsis Age and Gender Considerations in Psychiatric Diagnosis by : William E. Narrow
Download or read book Age and Gender Considerations in Psychiatric Diagnosis written by William E. Narrow and published by American Psychiatric Pub. This book was released on 2008-05-20 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written to help identify major gaps in our knowledge of how gender and age affect psychiatric diagnoses and to stimulate much-needed research to fill these gaps, Age and Gender Considerations in Psychiatric Diagnosis serves as both a valuable short-term source for the DSM-V Task Force and its disorder-specific workgroups, and a long-term guide for future studies that will contribute to revised psychiatric classifications in these three areas. Here, 47 experts present findings in three areas of psychiatric research that historically have been neglected but rightfully have received increasing attention in recent years and thus are worthy of investigation into their clinical features, etiology, and course: 1. Significant gender differences in prevalence, symptom profiles, and risk factors for mental disorders, including neurodevelopmental, neurophysiological, and environmental factors for men and women that cut across diagnostic categories-for example, the critical importance of gender in how psychiatric illness develops and presents; DSM's approach to gender to date; and relevant research findings and gaps in the epidemiology, etiology, and pathophysiology of disorders and the gender-related expression of psychopathology, including the controversial and complex question of whether DSM should have different diagnostic criteria for men and women. 2. Mental disorders in infancy and early childhood, including diagnosis and measurement of psychopathology; PTSD and social and cognitive factors related to the experience of stress; reactive attachment disorder (unique in part because of its specificity to early childhood); mood and anxiety disorders and difficulties in diagnosis; sleep disorders, including two new disorders, Night-Waking Dysomnia and Sleep-Onset Dysomnia; feeding disorders, including the need to address overeating and overfeeding (especially given the alleged U.S. epidemic of obesity); early childhood manifestations of behavior disorders; and early symptoms and diagnosis of autism. 3. Mental disorders in the elderly, such as dementia and depression, once considered normal consequences of aging but now understood to represent mental disorders, including the need to identify specific brain structure abnormalities, biomarkers, and the many contributing biological, psychosocial, and environmental factors of mental illness in late life and to understand their roles in the elderly to better diagnose and monitor disease progression. Written for clinicians and researchers alike, this thought-provoking compendium contributes critical information that helps enhance our understanding of the causes of mental disorders, develop effective preventive and treatment interventions, and inform future editions of DSM and ICD.

Download or read book Lectins and Cancer written by Hans-Joachim Gabius and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular recognition undoubtedly governs any aspect of cellular interaction. To understand tumor cell growth regulation and spread, analysisof protein carbohydrate interactions can contribute to lead to the establishment of rational methods for diagnosis and therapy. Chemically and biochemically optimized preparation of adequate tools, their application for localization of receptor (tissue lectin) and ligand (cellular glycoconjugate) pairs in tumor cells and tumor sections and the usefulness of a lectin from a plant extract as potent immunomodulator indicate the prospect for a place of such techniques in pathology and oncology.

This book was released on 2012-12-06 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past half century, filamentous fungi have grown in commercial importance not only in the food industry but also as sources of pharmaceutical agents for the treatment of infectious and metabolic diseases and of specialty proteins and enzymes used to process foods, fortify detergents, and perform biotransformations. The commercial impact of molds is also measured on a negative scale since some of these organisms are significant as pathogens of crop plants, agents of food spoilage, and sources of toxic and carcinogenic compounds. Recent advances in the molecular genetics of filamentous fungi are finding increased application in the pharmaceutical, agricultural, and enzyme industries, and this trend promises to continue as the genomics of fungi is explored and new techniques to speed genetic manipulation become available. This volume focuses on the filamentous fungi and highlights the advances of the past decade, both in methodology and in the understanding of genomic organization and regulation of gene and pathway expression.

Book Synopsis Landscape Genetics by : Niko Balkenhol
Download or read book Landscape Genetics written by Niko Balkenhol and published by John Wiley & Sons. This book was released on 2015-11-09 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: LANDSCAPE GENETICS: CONCEPTS, METHODS, APPLICATIONS LANDSCAPE GENETICS: CONCEPTS, METHODS, APPLICATIONS Edited by Niko Balkenhol, Samuel A. Cushman, Andrew T. Storfer, Lisette P. Waits Landscape genetics is an exciting and rapidly growing field, melding methods and theory from landscape ecology and population genetics to address some of the most challenging and urgent ecological and evolutionary topics of our time. Landscape genetic approaches now enable researchers to study in detail how environmental complexity in space and time affect gene flow, genetic drift, and local adaptation. However, learning about the concepts and methods underlying the field remains challenging due to the highly interdisciplinary nature of the field, which relies on topics that have traditionally been treated separately in classes and textbooks. In this edited volume, some of the leading experts in landscape genetics provide the first comprehensive introduction to underlying concepts, commonly used methods, and current and future applications of landscape genetics. Consistent with the interdisciplinary nature of the field, the book includes textbook-like chapters that synthesize fundamental concepts and methods underlying landscape genetics (Part 1), chapters on advanced topics that deserve a more in-depth treatment (Part 2), and chapters illustrating the use of concepts and methods in empirical applications (Part 3). Aimed at beginning landscape geneticists and experienced researchers alike, this book will be helpful for all scientists and practitioners interested in learning, teaching, and applying landscape genetics.
