Download or read book New Strategies in Locust Control written by S. Krall and published by Birkhäuser. This book was released on 2012-12-06 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the late eighties large-scale control operations were carried out to control a major desert locust upsurge in Africa. For the first time since the banning of organochlorine pesticides these operations relied mainly on non-persistent pesticides such as organophosphates and pyrethroids. The amount of pesticides sprayed and the area covered were probably the highest in the history of locust control and raised criticism with respect to efficacy, economic viability and environmental impact. As a consequence, applied research into the problem was intensified, both at the national and the international level, with the goal of finding new and environmentally sound approaches and solutions to locust and grasshopper control. Emphasis was laid on developing new control agents and techniques.

Download or read book Copper Deficiency and Toxicity written by Charles Archibald Owen and published by William Andrew. This book was released on 1981 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: A reference text for biochemical and clinical researchers reviews current knowledge of clinical and biochemical aspects of copper (Cu) deficiency and toxicity. Topics include: observations of acquired Cu deficiency in animal species; Cu deficiency arising from in vivo Cu complexing agents; inherited Cu deficiency (Menkes' desease and animal models thereof); acquired Cu toxicity in microorganisms, plants, and animals; human acquired Cu toxicity (intentional and unintentional Cu toxicity; medicalaspects of human Cu toxicity; toxicity treatment; non-Wilsonian liver disease); and beneficial applications ofCu toxicity and Cu therapy (e.g., antitumor therapy; treating infectious diseases; anti-inflammatory applications; Cu intrauterine devices; Cu supplementation.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive survey of element requirements and cycling in algae, as well as in-depth information on element cycling in wetlands and the environment. Wetland classification, hydrology, soils, vegetation, and productivity are also presented. Additional topics covered include essentiality and toxicity of elements for plants; uptake, assimilation, and storage of micronutrients; uptake and accumulation of heavy metals; primary productivity, growth rates, and limitation in algae as well as eutrophication. Packed with figures, tables, and references, the book is valuable to students and researchers in wetlands science, phycology, and ecology, as well as to environmental managers and consultants.

Download or read book Bioremediation of Agricultural Soils written by Juan C. Sanchez-Hernandez and published by CRC Press. This book was released on 2019-03-14 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: The quality of agricultural soils are always under threat from chemical contaminants, which ultimately affect the productivity and safety of crops. Besides agrochemicals, a new generation of substances invades the soil through irrigation with reclaimed wastewater and pollutants of organic origin such as sewage sludge or cattle manure. Emerging pollutants such as pharmaceuticals, nanomaterials and microplastics are now present in agricultural soils, but the understanding of their impact on soil quality is still limited. With focus on in situ bioremediation, this book provides an exhaustive analysis of the current biological methodologies for recovering polluted agricultural soils as well as monitoring the effectiveness of bioremediation.

Download or read book Alphaherpesviruses written by Sandra Knowles Weller and published by Caister Academic Press Limited. This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alphaherpesviruses are a fascinating group of DNA viruses that includes important human pathogens such as herpes simplex virus type 1 (HSV-1), HSV-2, and varicella-zoster virus (VZV): the causative agents of cold sores, genital ulcerous disease, and chickenpox/shingles, respectively. A key attribute of these viruses is their ability to establish lifelong latent infection in the peripheral nervous system of the host. Such persistence requires subversion of the host's immune system and intrinsic antiviral defense mechanisms. Understanding the mechanisms of the immune evasion and what triggers viral reactivation is a major challenge for today's researchers. This has prompted enormous research efforts into understanding the molecular and cellular biology of these viruses. This up-to-date and comprehensive volume aims to distill the most important research in this area providing a timely overview of the field. Topics covered include: transcriptional regulation, DNA replication, translational control, virus entry and capsid assembly, the role of microRNAs in infection and oncolytic vectors for cancer therapy. In addition there is coverage of virus-host interactions, including apoptosis, subversion of host protein quality control and DNA damage response pathways, autophagy, establishment and reactivation from latency, interferon responses, immunity and vaccine development. Essential reading for everyone working with alphaherpesviruses and of interest to all virologists working on latent infections.
