Plant Nutrient Acquisition: New Perspectives
ISBN: 9784431669043 / Angielski / Miękka / 520 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. New research reveals that plants actively acquire nutrients; the acquisition process is not a passive one in which plants simply wait for dissolved nutrients to come closer to their roots. In fact plants play a far more active role than once was understood to be possible in nutrient acquisition and in adaptation to problem soils. This book presents an excellent overview and summary of new concepts of plant nutrient acquisition mechanisms, and sets forth their practical implications in crop production. The scope is wide ranging, from biochemical, molecular, and genetic analysis of nutrient...

Contraceptive Steroids: Pharmacology and Safety
ISBN: 9781461293132 / Angielski / Miękka / 395 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. One of the United States Food and Drug Administration's most difficult tasks is the assessment of risk-benefit ratios for a broad spectrum of therapeutic and prophylactic drugs. Furthermore, it is now widely recog- nized that no drug, chemical or even natural substance is completely devoid of risk. Nowhere has this issue been the subject of more controversy than with steroidal contraceptive drugs. Regulated as a special class of products because of their prophylactic use in healthy individuals for prevention of pregnancy rather than for treatment of disease, steroid contraceptives drugs...

Auditory Frequency Selectivity
ISBN: 9781461293163 / Angielski / Miękka / 456 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. One of the most fundamental aspects of the auditory system is its frequency selectivity - the ability to resolve a complex sound into frequency compOhents. This ability plays a role in many aspects of auditory perception, including: the masking of one sound by another; the perception of pitch for pure tones and complex tones; the perception of timbre; the perception of the relative phase of components in complex sounds; and the perception of loudness. Over the last decade, there have been considerable advances in our understanding of frequency selectivity, both at the physiological and...

Post-Harvest Physiology and Crop Preservation
ISBN: 9781475700961 / Angielski / Miękka / 572 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Emphasis in agricultural research for many years has concen- trated on crop production. This emphasis has become more important in recent years with the realization that the population worldwide is outstripping the food supply. There is, however, another side to increasing the availability of the food supply. This simply involves preservation of the harvested crop-for human consumption. The losses incurred in harvesting, handling, transportation, storage and marketing crops have become a greater problem as the distance from the farm to the ultimate consumer increases. In the Western world...

Der Wald ist die machtvollste Entfaltung pflanzlichen Lebens auf der Erdfeste, machtvoll nicht nur im Bild seiner auBeren Er scheinung, machtvoll vor allem in der unaufhaltsamen Gewalt der Durchsetzung gegenuber anderen Pflanzengesellschaften. Oberall dort, wo die Bedingungen des Makroklimas Baumen ein dauern des Gedeihen erlauben, verdrangt Wald fruher oder spater die Grasflur, die Heide, das Buschland, erobert er die yom Menschen nicht mehr verteidigten Ackerfluren zuruck, lost sie ab und be hauptet dann seine Herrschaft.

The Story of Our Trees: In Twenty-Four Lessons
ISBN: 9781107662780 / Angielski / Miękka / 174 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Originally published in 1912, as part of the Cambridge Nature Study Series, this book was written to provide children with a practical guide to trees.

Population Genetics of Forest Trees: Proceedings of the International Symposium on Population Genetics of Forest Trees Corvallis, Oregon, U.S.A., July
ISBN: 9789401052511 / Angielski / Miękka / 423 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Tropical climates, which occur between 2330'N and S latitude (Jacob 1988), encompass a wide variety of plant communities (Hartshorn 1983, 1988), many of which are diverse in their woody floras. Within this geographic region, temperature and the amount and seasonality of rainfall define habitat types (UNESCO 1978). The F AO has estimated that there 1 are about 19 million km of potentially forested area in the global tropics, of which 58% were estimated to still be in closed forest in the mid-1970s (Sommers 1976; UNESCO 1978). Of this potentially forested region, 42% is categorized as dry...

A Re-Appraisal of Forestry Development in Developing Countries
ISBN: 9789400968592 / Angielski / Miękka / 178 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This book is directed at foresters who work, or have an interest, in the developing world, and at development analysts and theorists who are concerned with the forestry sector. Most readers will be aware that in recent years, some fundamental changes in thinking about the development process in very poor countries have occurred. At one level, the underdevelopment problem has been explained as a lack of absorptive capacity, or implementation ability in very poor countries. However, it now seems that these are only symptoms of a more profound ailment in the whole economic structural and...

The quality of human life has been maintained and enhanced for generations by the use of trees and their products. In recent years, ever rising human population growth has put a tremendous pressure on trees and tree products; growing awareness of the potential of previously unexploited tree resources; and environmental pollution have both accelerated the development of new technologies for tree propagation, breeding and improvement. Biotechnology of trees may be the answer to solve the problems which can not be solved by conventional breeding methods. The combination of biotechnology and...

There is dismay, followed by outcry, and demands to Authority. Authority remembers its experts or appoints some: they ought to know. The experts advise a Cure. The Cure can be almost anything: holy water from Mecca, a Government Commis- sion, a culture of bacteria, poison, prayers denunciatory or tactful, a new god, a trap, a Pied Piper. The Cures have only one thing in common: with a little patience they always work. They have never been known entirely to fail. Likewise they have never been known to prevent the next outbreak. For the cycle of abundance...

Differentiation of Protoplasts and of Transformed Plant Cells
ISBN: 9783662218167 / Angielski / Miękka / 157 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. H. BINDING and J. REINERT In collaboration with the first authors of this volume This volume is devoted to the development of cell clones and plants from ma- nipulated cells: isolated protoplasts, cell fusion bodies, and transformed cells. Isolated protoplasts represent cells which are liberated from their walls and separated from the differentiation pattern of the organism. Investigations on re- generation from protoplasts provide a better understanding of the process and control of developmental pathways. Whereas protoplast isolation results in alteration of the state of differentiation of...
