Bedienteile an Handpressen und anderen Werkzeugmaschinen (Forschungsberichte des Landes Nordrhein-Westfalen #1269)

by Henning Wode

Über die zweckmäßige Art und günstige räumliche Anordnung von Bedienteilen - wie Handräder, Kurbeln und Hebel-gibt es eine umfangreiche Literatur. Sie ist jedoch fast ausnahmslos beschränkt auf folgende Anwendungsfälle : 1. a) Einstellen eines mit dem Bedienteil gekoppelten Zeigers auf eine gewünschte Lage. b) Nachfahren einer sich bewegenden Marke mit einem Zeiger, der mit dem Bedienteil gekoppelt ist. c) Fälle a) und b) jeweils bei einer Teil- oder vollen Umdrehung oder bei meh­ reren Umdrehungen des Bedienteils ; bei unterschiedlichen Drehwider­ ständen. 2. a) Einleitung eines möglichst großen Energiebetrages in das Bedienteil bei einer Umdrehung oder mehreren aufeinanderfolgenden Umdrehungen des Bedienteiles. b) Einleiten eines möglichst großen statischen Drehmomentes oder einer mög­ lichst großen Kraft in das ganz oder nahezu feststehende Bedienteil. Anscheinend fehlen aber noch Untersuchungen über die zweckmäßige Art und Lage von Bedienteilen, an denen vom Menschen Arbeit geleistet werden soll, in­ 0 dem er sie um weniger als 360 wiederholt gegen einen Arbeitswiderstand hin­ bewegt und unbelastet zurückbewegt. Da solche Arbeitsbedingungen in der Praxis häufig vorkommen - wie u. a. in diesem Bericht nachgewiesen wird -, ist eine Untersuchung hierüber angebracht. Um Klarheit für den folgenden Bericht zu schaffen, müssen zunächst einige De­ finitionen gegeben werden: »Handpresse« ist eine Presse, deren für den Arbeitsvorgang notwendige Energie vom Menschen über seine Hand in sie eingeleitet wird. Die Energiezufuhr durch den Menschen erfolgt über das »Bedienteil« : »Bedienteil« ist das Bauteil, über das ein Mensch auf eine Vorrichtung die für die Arbeitsaufgabe nötige Energie überträgt.

The Bedrock of Opinion: Science, Technology and Society in the Siting of High-Level Nuclear Waste (Environment & Policy #32)

by G. Sundqvist

When did man discover nuclear waste? To answer this question, we first have to ask if nuclear waste really is something that could be called a scientific discovery, such as might deserve a Nobel Prize in physics. In early writings within nuclear energy research radioactive waste appears to be a neglected issue, a story never told. Nuclear waste first seems to appear when a public debate arose about public health risks of nuclear power in the late 1960s and early 70s. In nuclear physics, consensus was established at an early stage about the understanding of the splitting of uranium nuclei. The fission products were identified and their chains of disintegration and radioactivity soon were well­ established facts among the involved scientists, as was an awareness of the risks, for example the strong radioactivity of strontium and iodine, and the poisonous effects of plutonium. However, the by-products were never, either in part or in total, called or perceived as waste, just as fission by-products. How and where to dispose of the by-products were questions that were never asked by the pioneers of nuclear physics.

The Bee Garden: How to Create or Adapt a Garden to Attract and Nurture Bees

by Maureen Little

Bees play a vital and irreplaceable role in pollinating our flowers, fruits and vegetables. The more bees in your garden the healthier, more productive and more pleasant a place it will be. Yet bees are declining rapidly and many people, even if they do not wish to keep bees themselves, are asking what can be done on an individual basis to help the bee. This book is a response to that request. It will demonstrate in one accessible volume how each of us can play our part in providing a bee-friendly environment, no matter how much gardening space and/or time we may have. It includes: * How bees forage, what bees you can expect to find in your garden and what plants are best for them. * Why honey bees are so important; what they need to thrive and how they detect and access those requirements; and what varieties of plants are best suited to provide those needs. * How the gardener can offer and maintain a bee-friendly garden, followed by a season-by-season account of what beefriendly plants are in flower and when, and what jobs the gardener can be doing during these times to help bees thrive. * A gazetteer of selected bee-friendly plants, arranged by type of plant in seasonal sub-sections. * Illustrative, practical planting plans, including a culinary herb garden, a potager, a wild flower garden, and a 3 seasons traditional border.

Bee-Inspired Protocol Engineering: From Nature to Networks (Natural Computing Series)

by Muddassar Farooq

Honey bee colonies demonstrate robust adaptive efficient agent-based communications and task allocations without centralized controls – desirable features in network design. This book introduces a multipath routing algorithm for packet-switched telecommunication networks based on techniques observed in bee colonies. The algorithm, BeeHive, is dynamic, simple, efficient, robust and flexible, and it represents an important step towards intelligent networks that optimally manage resources. The author guides the reader in a survey of nature-inspired routing protocols and communication techniques observed in insect colonies. He then offers the design of a scalable framework for nature-inspired routing algorithms, and he examines a practical application using real networks of Linux routers. He also utilizes formal techniques to analytically model the performance of nature-inspired routing algorithms. In the last chapters of the book, he introduces an immune-inspired security framework for nature-inspired algorithms, and uses the wisdom of the hive for routing in ad hoc and sensor networks. Finally, the author provides a comprehensive bibliography to serve as a reference for nature-inspired solutions to networking problems. This book bridges the gap between natural computing and computer networking. What sets this book apart from other texts on this subject is its natural engineering approach in which the challenges and objectives of a real-world system are identified before its solution, nature-inspired or otherwise, is discussed. This balanced exposition of the book makes it equally suitable for telecommunication network designers and theorists, and computer science researchers engaged with artificial intelligence, agents, and nature-inspired techniques.

The Bee-Kind Garden: Apian wisdom for your garden (Wise Words #1)

by David Squire

The lives of bees are interwoven with our own, but how much do you know about them?Which scents do bees prefer? How do bees transport pollen? How far can bees fly? Do specific colours attract bees? Do bees prefer native flowers? Bees are a delight to see in the garden on warm summer days, buzzing as they flit from flower to flower. They are also vital for the future of the planet and without their dedicated pollinating skills, many crops would eventually fail. Then there is honey – a near-miraculous elixir that in earlier generations was an integral part of life as a sweetener and food preserver. It can be fermented with water and yeast to create mead, a drink that has been enjoyed for thousands of years. The Bee-Kind Garden reveals the many facets of the lives of bees, including their hives, flight patterns and defence. It is filled with helpful information on important topics such as which flowers are best for attracting bees to your garden, beekeeping equipment and guidance for extracting honey as well as the art of talking to bees. It also celebrates the charming proverbs, limericks and verse bees have inspired.This delightfully illustrated book is a homage to bees and to ensuring that they continue to live in harmony with humans in bee-friendly gardens.

Bee Pollination in Agricultural Ecosystems

by Rosalind James Theresa L. Pitts-Singer

For many agricultural crops, bees play a vital role as pollinators, and this book discusses the interplay among bees, agriculture, and the environment. Although honey bees are well recognized as pollinators, managed bumble bees and solitary bees are also critical for the successful pollination of certain crops, while wild bees provide a free service. As bees liberally pass pollen from one plant to the next, they also impact the broader ecosystem, and not always to the benefit of humankind. Bees can enhance the unintentional spread of genes from genetically engineered plants, and may increase the spread of invasive weeds. Conversely, genetically engineered plants can impact pollinators, and invasive weeds can supply new sources of food for these insects. Bees' flower-visiting activities also can be exploited to help spread biological control agents that control crop pests, and they are important for native plant reproduction. Managing bees for pollination is complex and the factors that must be taken into consideration are treated here, including bee natural history, physiology, pathology, and behavior. Furthermore, transporting bees from native ranges to new areas for pollination services can be controversial, and needs to be done only after assuring that it will not disrupt various ecosystems. Even though bees are small, unobtrusive creatures, they play large roles in the ecosystem. The connection between bees and humankind also is symbolic of a broader interconnection between humans and the natural world.
