Organic chemistry is the chemistry of compounds of carbon. The ability of carbon to link together to form long chain molecules and ring compounds as well as bonding with many other elements has led to a vast array of organic compounds. These compounds are central to life, forming the basis for organic molecules such as nucleic acids, proteins, carbohydrates, and lipids. In this Very Short Introduction Graham Patrick covers the whole range of organic compounds and their roles. Beginning with the structures and properties of the basic groups of organic compounds, he goes on to consider organic compounds in the areas of pharmaceuticals, polymers, food and drink, petrochemicals, and nanotechnology. He looks at how new materials, in particular the single layer form of carbon called graphene, are opening up exciting new possibilities for applications, and discusses the particular challenges of working with carbon compounds, many of which are colourless. Patrick also discusses techniques used in the field. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.
Völlig ausgeblutet wird die Leiche eines Afrika-Experten an einem tristen Wintertag aufgefunden. Allerfeinste Profiarbeit, wie Kriminalrat Max Pfeffer von der Münchner Kripo feststellt. Eine Holzfigur, ein toter Galerist und die schöne Helene - Max Pfeffer ist nicht in seinem Element. Sein Kunstverständnis beschränkt sich auf coolen Acid Jazz und mit Frauen hat er´s überhaupt nicht. Pfeffer wohnt mit seinem Lebensgefährten in einem Münchner Einfamilienhaus und müht sich mit der Erziehung zweier Söhne ab. Während sein Zwölfjähriger gerade erst Britney Spears für sich entdeckt, ist Cosmo Frontman der Hiphop-Band Volle Härte und dem Vater schon mit sechzehn über die Kopf gewachsen - und er unterschlägt unwissentlich ein wichtiges Beweisstück in Pfeffers neuem Fall. Was hat Afrika mit dem Mord zu tun - die ehemals deutsche Kolonie Kamerun, der Stamm der Ndjamele, die Legende von Akassi und Awali? Tod nach Kolonialherrenart? Pfeffer muss sich mit einer dunklen Epoche der deutschen Geschichte auseinandersetzen, denn die Wurzeln des Verbrechens gehen zurück in die Zeit, als über Kamerun die Flagge des Deutschen Kaiserreiches wehte. Damals schenkte ein schwarzer Fürst einem deutschen Kolonialpionier eine Sklavin.

The diazotisable amine, p-aminoacetophenone has been diazotized with nitrite in the presence of hydrochloric acid at room temperature, and the diazotized salt thus produced has been allowed to couple with the reagent, 2,3-dihydroxynaphthalene in alkaline medium to produce a reddish orange azo-dye suitable for the determination of nitrite at ppm level. The max of the azo-dye being 475 nm. The very azo-dye is extractable into an organic solvent like ethylacetate without shifting the max. Similarly, nitrate ion forms a strong reddish-yellow nitro product with 2,3 dihydroxynaphthalene in the presence of concentrated sulfuric acid. This nitro product is extractable into ethylacetate, and its absorbance is measured at 380nm ( max ).The Beer s law for nitrite and nitrate were obeyed in the range, 0.1 to 5.0 ppm and 0.2 to 25 ppm, respectively. The molar absorptivity of nitrite and nitrate methods are 2.5 104 and 3.2 103 L.mol-1cm-1 respectively. The RSD for both the methods are in the range, 0.5 to 2.5%.
Designed for health practitioners, nutrition professionals, college coursework, or the sophisticated lay reader, this ´´comprehensive´´ edition includes a chapter on eating disorders, additional charts, graphs and tables, and more than 100 pages of references that are not included in Becoming Vegan: Express Edition. The authors expand their discussion of: the health benefits of vegan diets compared to other dietary choices; protein and amino acid requirements at various stages of life; the value of fats and essential fatty acids in plant-based diets; and carbohydrate facts and fallacies. They also pinpoint where to obtain calcium, iron, zinc and other minerals (including B12) without animal products; show how to attain optimal nutrition during pregnancy and lactation, and how to achieve and maintain healthy weights and exceptional fitness on a vegan diet. Nutritional guidelines are provided for infants, children, teens, and adults, including seniors. Tables and graphs covering nutrient intakes, composition breakdowns, and food sources based on vitamin and mineral content illustrate each section. A handy graphic of the vegan plate offers a daily plan for healthful eating, and sample menus designed for people of various caloric needs are provided. An opening chapter is devoted to the impact of animal agriculture on the environment, and the degree of inhumanity that has dominated the industry.
This book is the result of remarkable contribution from the experts of interdisciplinary fields of Science with comprehensive, in-depth and up-to-date research and reviews.? It describes the applications of date palm for food, medicine and the environmental sectors. Date palm is one of the oldest cultivated trees and its fruit has been a dietary staple around the world for many centuries. Date pulps contain dietary fibers and easily digestible sugars (70%), mainly glucose, sucrose and fructose. They also contain vitamins like biotin, thiamine, riboflavin, ascorbic and folic acid that are important for our body. The date palm fruit has been used in folk remedies for the treatment of various infectious diseases, cancer and immuno-modulatory activity. Date stones and date palm leaves are freely and abundantly available biomass. Therefore, the renovation of agricultural biomass wastes into activated carbons for drinking water purification, wastewater treatment, treatment of dyes, and metal-ions from aqueous solution would add value to agricultural commodities which offer a solution to environmental problems as well as reduce the cost of waste disposal.
The aim of this book is to further highlight the importance of media composition on gene expression. Under conditions of iron limitation, Pseudomonas aeruginosa secretes pyoverdine to help bind iron from the external environment. The ferripyoverdine receptor, fpvA , is the receptor P. aeruginosa uses to internalize iron bond to pyoverdine. FpvA was cloned and identified to have a molecular mass of 89,395 daltons (Meyer et al., 1990, Poole et al., 1993) . In addition to playing the role of a receptor to iron bound to pyoverdine, the fpvA gene has also been hypothesized to be targeted by antibiotics and bacteriophages and serve as entry points for them. The arylamidase enzyme (EC 184.108.40.206] is the enzyme that catalyzes the hydrolysis of an N-terminal amino acid from peptides, amides or arylamides. It was purified decades ago and was estimated to weigh about 71 kDa by Riley and Behal (1970). The fpVA and the arylamidase enzyme may possibly interact or may be similar in their manner of functioning based on scientific observations decades ago from the research work done by Riley and Behal (1970), and the recent observations by Osayande, JO (2013) and Bishop et al., 2017.

The entire range of the developmental process in plants is regulated by a shift in the hormonal concentration, tissue sensitivity and their interaction with the factors operating around the plants. Phytohormones play a crucial role in regulating the direction of plant in a coordinated fashion in association with metabolism that provides energy and the building blocks to generate the form that we recognize as a plant. Out of the recognized hormones, attention has largely been focused on Auxins, Gibberellins, Cytokinins, Abscisic acid, Ethylene and more recently on Brassinosteroids. In this book we are providing the information about a brassinosteroids that again confirm its status as phytohormones because it has significant impact on various aspects of the plant life and its ubiquitous distribution throughout the plant kingdom. Brassinosteroids are generating a significant impact on plant growth and development, photosynthesis, transpiration, ion uptake and transport, induces specific changes in leaf anatomy and chloroplast structure. This book is not an encyclopedia of reviews but includes a selected collection of newly written, integrated, illustrated reviews describing our knowledge of brassinosteroids. The aim of this book is to tell all about brassinosteroids, by the present time. The various chapters incorporate both theoretical and practical aspects and may serve as baseline information for future researches through which significant development is possible. It is intended that this book will be useful to the students, teachers and researchers, both in universities and research institutes, especially in relation to biological and agricultural sciences.
In the innovative field of cosmetic dermatology, the range of products and methods available to patients is expanding all the time. Prominent among these are facial fillers, which, when injected into and beneath the skin, help alleviate wrinkles and improve smoothness. However, the many fillers on offer have varying characteristics and effects, and practitioners must be properly trained in order to administer them safely and successfully. Injectable Fillers offers those performing these popular procedures an in-depth and far-reaching survey of current best practices, with a strong emphasis on safety. Covering everything from the science behind facial fillers to their appropriate means of application, the book places each product in context, demonstrating the pros and cons of the expanding range of hyaluronic acids and calcium hydroxylapatite microspheres, and exploring injectable submental fat reduction with sodium deoxycholate. This second edition broadens the scope of discussion to also include chin, mandible, temple, nose, brow, and forehead injections, as well as the use of cannulas as an alternative to needles.
