This collection reviews current research on understanding nutrient cycles, the ways crops process nutrients, the environmental effects of fertilizer use and how this understanding can be used to improve nutrient use efficiency for a more resource-efficient and climate-smart agriculture. Parts 1-3 summarise research on the primary macronutrients: nitrogen, phosphorus and potassium. Chapter review what we know about nutrient cycles, crop nutrient processing, potential environmental effects and ways of optimising nutrient use efficiency (NUE). The fourth section of the book discusses secondary macronutrients and micronutrients including: calcium, magnesium, sulphur, zinc, boron, manganese and m...
Hvor intet bryder vinden er en samtidsthriller inspireret af de klassiske mysterier og et portræt af syv meget forskellige mennesker, der bliver tvunget til at se deres fortrængninger i øjnene.
Een sensuele roman over de duistere kant van de menselijke natuur.’ – Erik Valeur Zeven kunstenaars en wetenschappers komen bij elkaar op Stormø, een onbewoond eiland voor de Deense kust. Ze kennen elkaar niet, maar ze ontvingen allemaal een anonieme uitnodiging om een maand lang in alle rust op het eiland te komen werken. Als blijkt dat hun tijdelijke huis volledig van glas is en ze volkomen afgesneden zijn van het vasteland, zijn de gasten meer op elkaar aangewezen dan ze lief is. Dan verdwijnt een van hen, en een ander komt dodelijk ten val. Langzaam wordt duidelijk dat de eilandgasten zonder het te weten een gedeeld verleden hebben, vol leugens en bedrog, en dat iemand doelbewust bezig is deze geheimen te ontrafelen.
This volume provides a comprehensive look at the biology of plastids, the multifunctional biosynthetic factories that are unique to plants and algae. Fifty-six international experts have contributed 28 chapters that cover all aspects of this large and diverse family of plant and algal organelles. The book is divided into five sections: (I): Plastid Origin and Development; (II): The Plastid Genome and Its Interaction with the Nuclear Genome; (III): Photosynthetic Metabolism in Plastids; (IV): Non-Photosynthetic Metabolism in Plastids; (V): Plastid Differentiation and Response to Environmental Factors. Each chapter includes an integrated view of plant biology from the standpoint of the plastid. The book is intended for a wide audience, but is specifically designed for advanced undergraduate and graduate students and scientists in the fields of photosynthesis, biochemistry, molecular biology, physiology, and plant biology.
Critique is the art of making judgments about something with reference to some standards. The question then arises: which standards? When we criticize a claim about state of affairs, a norm or a piece of art, on the basis of what do we do so? Which are our yardsticks? This book is presenting, discussing and assessing, from various perspectives, how feminists have approached such questions. The first part of the dissertation takes up the challenge posed by feminist epistemology. Feminist epistemologists question prevalent ideas of objectivity and good science. How have they done this? And are their claims well-founded? The second part takes a closer look at the meta-debates going on in contem...
Plants depend on physiological mechanisms to combat adverse environmental conditions, such as pathogen attack, wounding, drought, cold, freezing, salt, UV, intense light, heavy metals and SO2. Many of these cause excess production of active oxygen species in plant cells. Plants have evolved complex defense systems against such oxidative stress. The
Using accessible farming practices to meet the growing demands on agriculture is likely to result in more intense competition for natural resources, increased greenhouse gas emissions, and further deforestation and land degradation, which will in turn produce additional stress in the soil-water-plant-animal continuum. Stress refers to any unfavorable force or condition that inhibits customary functioning in plants. Concurrent manifestations of different stresses (biotic and abiotic) are very frequent in the environment of plants, which consequently reduces yield. Better understanding stress not only changes our perspective on the current environment, but can also bring a wealth of benefits, ...
