Taschenbuch. Condición: Neu. Druck auf Anfrage Neuware - Printed after ordering - Scientific Study from the year 2010 in the subject Forestry / Forestry Economics, grade: 1, Shaheed Benazir Bhutto University, course: M.Sc/BS Hons 4 Years Forestry, language: English, abstract: The study was carried out in District Nowshera at 10 different locations namely; Nizampur, Akora khattak, Pirsabaq, Khat kaly, Azaa kheel, Chirrat, Khweshgi, Behraam kaly, Rashakai, Pabbi, and Kaka sahib through questionnaire in order to gather the information from beekeepers to investigate the predators and parasites of honey bee that causes the losses of honey production and on honey bees. The results show that mites caused severe loss of honey production (35.21%) followed by bee-eaters (21.69%), wax moth (21.63%), black aunts (14.79%) and hornets (6.77%) respectively in the study area. This research was conducted to determine the bee predators and parasites that causes the loss of honey production and honey bees in Nowshera District, Khyber Pukhtunkhwa.…

Taschenbuch. Condición: Neu. Druck auf Anfrage Neuware - Printed after ordering - Wissenschaftliche Studie aus dem Jahr 2012 im Fachbereich Umweltwissenschaften, Shaheed Benazir Bhutto University, Sprache: Deutsch, Abstract: AbstractThe improper disposal of municipal waste has a serious and dangerous impact on a wide range of areas. Garbage thrown in the street or in open spaces creates a public health hazard, while waste dumped near rivers, lakes and streams contaminates the water supply. Rubbish that is burned in the open rather than disposed of properly creates pollution and releases toxic fumes into the environment. Non-biodegradable materials thrown into open drains make their way into the sewerage system, clogging pipelines and damaging infrastructure. The hazards posed by the dumping of untreated hospital and industrial waste are even greater, with the release of pathogens and toxic compounds posing a grave threat not just to human life but also to plants and animals. Garbage dumped in the countryside is not simply an eyesore; entire landscapes are ruined and unique habitats for flora and fauna are lost. All of these problems are common in Pakistan(home of natural Beauty), where vast quantities of solid waste remain uncollected in the streets, along major roads, in empty plots of land, down hill slopes and in illegal dumps.…

Taschenbuch. Condición: Neu. Druck auf Anfrage Neuware - Printed after ordering - Plant foods are an essential part of our daily diet and constitute one of the highest contributors to the world economy. These foods are rich in phenolic compounds, which play a significant role in maintaining our health. This textbook presents a comprehensive overview of the chemistry, biochemistry and analysis of phenolic compounds present in a variety of foods. The text can be used as a singular source of knowledge for plant food science and technology, covering all of the important chemical, biochemical and analytical aspects needed for a thorough understanding of phenolic antioxidants in foods.Phenolic Antioxidants In Foods: Chemistry, Biochemistry, and Analysis is comprised of three sections. The first section covers the basic concepts of antioxidants, their chemistry and their chemical composition in foods, providing a detailed introduction to the concept. The second section covers the biochemical aspects of phenolic antioxidants, including their biosynthetic pathways, biological effects and the molecular mechanism of antioxidant effects in the biological system. This section promotes an understanding of the fundamental biochemical reactions that take place in foods and after digestion and absorption. The third section covers the analytical chemistry used in the analysis of phenolic antioxidants in foods, including the basic analytical procedures, methods for analysis and chromatographic and spectroscopic analyses. This section is significant for aspiring food chemists and manufacturers to evaluate the nature and chemistry of phenolic antioxidants in foods. Featuring helpful quizzes, section summaries, and key chapter points, this textbookis the perfect learning tool for advanced chemistry undergraduates and post-graduates looking to gain a fundamental understanding of phenolic antioxidants in food products.…
