Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Hazardous waste has been defined as waste that is either in a solid, liquid, or gas form, which contributes significantly to serious irreversible or incapacitating reversible illnesses and poses a potential hazard to human health or the environment, depending on its quantity, concentration, and physical, chemical, or infectious characteristics. Hazardous waste risk assessment is a quantitative means of assessing the potential adverse effects of exposure on human health.Management of hazardous waste is a very important process for saving the environment and human life. Traditional and innovative techniques for the treatment and solidification of hazardous waste make for interesting research and study. Proper storage of hazardous waste ensures proper segregation of waste, separation of incompatible wastes, easy access to wastes, reasonable protection against vandalism, and adequate secondary containment. Hazardous wastes are generally stored in different modified containers, including drums and tanks. Prevention or minimization of hazardous waste and improving control methods are introduced as risk management options.Many countries, including developing countries, have taken steps in the right direction to minimize and manage hazardous waste, not only by cleaning up contaminated sites, but also by controlling and reducing the generation of hazardous wastes. 92 pp. Englisch.

Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -What do we talk about when we talk about antiquity For the majority of the population, the term immediately transports us to the notion of an ancient age or ancient world (the Parthenon, Athens, and the Coliseum of Rome), which condenses in itself the Greco-Roman world. This reduces antiquity to antiquity that was structurally essential for the construction and emergence of the civilization called occidental.For others, because of their religious backgrounds, antiquity goes back in time and enlarges, in part, its space of action, allowing the emergence of Palestine as a primordial territory.But these two visions (old and supported by a scientific ignorance of the ancient geographies and chronologies) enclose the history in a limited time and space. As if there would never have been a world before that time. As if the civilization that we comfortably call ourselves as inheritors, the so-called 'Occidental Civilization' was the first step in the history of man on earth. 86 pp. Englisch.

Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Insect protein production through ¿mini-livestock farming¿ has enormous potential to reduce the level of malnutrition in critical areas across the world. It has been estimated that insect eating is practised regularly by over two billion people, mostly in China and in most tropical countries in Africa, South America, and Asia. However, eating insects has been taboo in many western nations. Reasons for this are discussed in this book with examples from Finland and the UK. The enormous boom of insect farming in Finland started in September 2017 when the business type was legalized. However, a large part of the population found the insect food too expensive and exotic. UK research outlines a multitude of promising strategies to overcome ¿western¿ resistance to eating insects. This book also includes a chapter on the potential of insect farming to increase global food security. It shows that Africa is a hotspot of edible insect biodiversity and there more than 500 species consumed daily. We have several examples of viable insect farming businesses that can fight poverty and malnutrition in developing countries and provide profit and wealth to rural farmers. The chapters of the book cover countries such as Cameroon, Ecuador, Finland, Ghana, India, Mexico, the UK, and the US. 98 pp. Englisch.

Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Seed dormancy and germination are critical processes for the development of plants. Seed dormancy allows seeds to overcome harsh periods of seedling establishment, and is also important for plant agriculture and crop yield. Several processes are involved in the induction of dormancy and in the shift from the dormant to the germinating state, and hormones and regulatory genetic networks are among the critical factors driving these complex processes. Germination can be prevented by different factors leading to seed dormancy, which is highly dependent on environmental cues. During and after germination, early seedling growth is sustained by catabolism of stored reserves (proteins, lipids, or starch) accumulated during seed maturation, supporting cell morphogenesis, chloroplast development, and root growth until photo-auxotrophic growth can be resumed. 158 pp. Englisch.

Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Owls are soft-plumaged, short-tailed, big-headed birds that have the most frontally situated eyes of all birds and they can blink the upper eyelids. This, together with a broad facial disc, gives owls all the right characteristics to make them attractive in our eyes. At the same time, some people fear their presence and even their calls, and there are more myths and beliefs about owls than there are about any other bird.Bats are often similarly feared as owls, partly because both of them inhabit the night; a place that is unknown and alien to us. Owls and bats symbolise all that is mysterious about the night and their complete mastery of the darkness only highlights our own deficiencies. In this book, we will get to know the relationships between bats and owls. This book describes the biological control of rats by owls in Malaysia, the prey-predator interactions in a tropical forest in Mexico, and provides an overview of the breeding biology of owls. From numerous owl belief and myth studies, described in this book are those of the lesser known Central Asian countries where owls are often worshipped for their supernatural powers. 112 pp. Englisch.

Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Lipid peroxidation is the major molecular mechanism that induces oxidative damage to cell structures and is also involved in the toxicity process that leads to cell death.Lipid peroxidation is a chain reaction initiated by the hydrogen abstraction or addition of an oxygen radical, resulting in the oxidative damage of polyunsaturated fatty acids (PUFA). PUFAs are more sensitive than saturated fatty acids because of the presence of a double bond adjacent to a methylene group that makes the methylene C-H bond weaker and therefore the hydrogen is more susceptible to abstraction. This leaves an unpaired electron on the carbon, forming a carbon-centered radical, which is stabilized by a molecular rearrangement of the double bonds to form a conjugated diene, which then combines with oxygen to form a peroxy-radical.In pathological situations the reactive oxygen and nitrogen species are generated at higher than normal rates, and as a consequence, lipid peroxidation occurs with deficiency of endogenous antioxidants as alpha-tocopherol deficiency or reduced glutathione. In addition to containing high concentrations of PUFAs and transition metals, biological membranes of cells and organelles are constantly being subjected to various types of damage.This book presents systematic and comprehensive reviews on free radicals and their involvement in lipid peroxidation with special emphasis on their important role in different diseases. 128 pp. Englisch.
