Download or read book Pyrethrum written by John Casida and published by Elsevier. This book was released on 2012-12-02 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pyrethrum: the Natural Insecticide covers the papers presented at the 1972 ""International Symposium on Recent Advances with Pyrethrum the Natural Insecticide"" held in conjunction with the American Institute of Biological Sciences Silver Anniversary Meeting at the University of Minnesota, Minneapolis. It deals with all aspects of pyrethrum, including its history, production, chemistry, biochemistry, toxicology, pharmacology, and agricultural applications. The introductory part addresses the early history of pyrethrum, its recognition as a modern insecticide, and its worldwide production. The chemistry and biochemistry parts discuss the composition, isolation, structure, synthesis, biosynthesis, metabolism, and action on enzyme systems of natural pyrethrins extracted from pyrethrum flower. The book also examines the toxicology of pyrethrum and its constituents to mammals, fish, and wildlife, as well as tests for possible teratogenic, carcinogenic, mutagenic, and allergenic activities. Finally, it discusses the domestic and agricultural applications of pyrethrum. Considering its desirable features, researchers find pyrethrum unsurpassed by any type of synthetic organic insecticide and even by the best synthetic analogs or pyrethroids.

Download or read book Plant Diseases and Vectors Ecology and Epidemiology written by Karl Maramorosch and published by Elsevier. This book was released on 2012-12-02 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant Diseases and Vectors: Ecology and Epidemiology is the fourth in a five-volume series of books on vectors of plant disease agents. It is comprised of 10 chapters representing the expertise of 13 outstanding scientists from a total of seven different countries. This book begins with a discussion on the ecological involvement of wild plants in plant virus pathosystems. This is followed by the principles and applications of enzyme-linked immunosorbent assay (ELISA) in diagnosing plant viruses and monitoring their movement in the environment. The next two chapters detail the epidemiologies of diseases caused by leafhopper-borne viruses, mollicutes, and rickettsia-like organisms. This book also covers the developments in understanding the importance of helper agents to the transmission ecologies of many aphid-borne plant viruses. It also encompasses the factors that can contribute to the epidemiology and control of a disease affecting a major agricultural crop of the world. A vector of plant viruses not covered in earlier volumes of the series (the host plant, itself) and the man-made epidemiological hazards in major crops of developing countries are also described. This volume will broaden the knowledge of transmission ecology and disease epidemiology, not only by serving as a valuable supplemental textbook, reference work, and bibliographical source, but also by catalyzing novel syntheses of thinking and stimulating further research in the area.

This book was released on 2012-12-06 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mter the discoveryof the tobacco mosaic virus by D. I. Ivanov skU in 1892 [14], the new science of virology was born and began to develop rapidly. The number of viruses now known is enormous and they can infect nearly all animal and plant organisms. Microorganisms themselves are no exception to this rule. Despite intensive study of Vlruses, their origin and nature are still a subject for speculation and hypothesis. The general concept of viruses embraces a wide group of biologically active structures occupying an intermediate position between living and nonliving matter. The dual character of viruses is determined by the fact that, while they do not possess an inde pendent system of metabolism, which is a characteristic feature of every living being, they nevertheless carry within themselves all the necessary information for autoreproduction. A striking feature of the virus is that it consists essentially of two components: a protein envelope and the nucleic acid con tained within it. In contrast to the elementary structural unit of the living or ganism, the cell, which contains two types of nucleic acid (DNA and RNA), the virus particle contains only one type of nucleic acid - either DNA or RNA. It is perhaps this which is responsible for the imperfection of the virus as a living organism.
Download or read book Feminist Philosophy of Mind written by Keya Maitra and published by Oxford University Press. This book was released on 2022 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This collection is the first book to focus on the emerging field of study called feminist philosophy of mind. Each of the twenty chapters of Feminist Philosophy of Mind employs theories and methodologies from feminist philosophy to offer fresh insights and perspectives into issues raised in the contemporary literature in philosophy of mind and/or uses those from the philosophy of mind to advance feminist theory. The book delineates the content and aims of the field and demonstrates the fecundity of its approach, which is centered on the collective consideration of three questions: What is the mind? Whose mind is the model for the theory? To whom is mind attributed? Topics considered with this lens include mental content, artificial intelligence, the first-person perspective, personal identity, other minds, mental attribution, mental illness, perception, memory, attention, desire, trauma, agency, empathy, grief, love, gender, race, sexual orientation, materialism, panpsychism, and enactivism. In addition to engaging analytic and feminist philosophical traditions, essays draw from resources in phenomenology, philosophy of race, decolonial studies, disability studies, embodied cognition theory, comparative philosophy, neuroscience, and psychology"--

Available in PDF, EPUB and Kindle. Book excerpt: A summary is presented of a research program aimed at the improvement of high-temperature strain gages of the electrical resistance type. Potential ceramic and metal components were evaluated and a gage was devised that was based on these evaluations. This gage (NBS 5B) was flexible and easy to install; however, it lacked resistance stability at higher temperatures. In an attempt to minimize this deficiency, ceramic cements were developed that showed greater electrical resistivity than had been previously observed in the range 800 to 1800 degrees Fahrenheit; also, a technique was devised for increasing the resistance to ground by applying a fired-on ceramic coating to the grid of a specifically developed unbacked gage. A study was made of the cause of the erratic response of cemented gages that had not been preheated prior to use. There were strong indications that the erratic response was caused mostly by the rapid decrease in resistance that accompanied structural changes in the cement.
