Book Description
The book covers information on some theoretical aspects related to working of light trap like organs of insect vision and orientation towards light source, electromagnetic radiation, spectrum visible/attractive to insects, characteristics of electric lamps used, factors affecting trap catches and identification of migratory phases based on analysis of light trap catches etc. Practical aspects include principles and practice of light trap operation, trap designs and light sources to be used and study of seasonal activity and direct control of pest population using light traps. Last chapter covers extensive reviews of field trials and experimental work conducted on survey and control of some economic species of crop pests. The manuscript is supplemented in the end with a list of references cited in the text along with selected references on light trap studies for consultation to all the concerned. The main objective of this book is to revive interest among the scientists, research scholars and students in using this novel technique of pest control and make it more popular among the farmers through research and extension work. We hope this book would serve as a reference/text book, meeting the essential requirements for advanced course 'Light trap as IPM tool'.

Book Description
As the judges of the Whitbread Prize noted, 'Burnside's poems have the rare power to alter one's perception of the world and of language...a sensory delight with an epiphany on every page.' Once again, in this, his eighth collection of poetry, John Burnside is looking deeply into the ways we see our world: addressing the organic relationship between the environment and the unconscious, between ideas and the creatures, in poems whose protagonists - from the deer who pass through a suburban garden to the poet's six-month-old son - are infinitely mysterious, difficult and 'out there'. These are poems that move beyond the traditional idea of 'nature poetry', investigating the very basis of our knowledge, not only of living things, but of the play of gravity and light that makes our world and theirs possible. Resonant and luminous, this is work of intimacy and wonder from one of Britain's most important poets.

Book Description
New Approaches to Light Trapping in Solar Cell Devices discusses in detail the use of photonic and plasmonic effects for light trapping in solar cells. It compares and contrasts texturing, the current method of light-trapping design in solar cells, with emerging approaches employing photonic and plasmonic phenomena. These new light trapping methods reduce the amount of absorber required in a solar cell, promising significant cost reduction and efficiency. This book highlights potential advantages of photonics and plasmonics and describes design optimization using computer modeling of these approaches. Its discussion of ultimate efficiency possibilities in solar cells is grounded in a review of the Shockley-Queisser analysis; this includes an in-depth examination of recent analyses building on that seminal work.

Book Description
A gripping wilderness adventure and survival story It was getting colder. Johnny pulled the fur-lined hood of his parka over his head and walked towards his own cabin with the sound of snow crunching beneath his boots. "He should be back tomorrow," he thought, as a star raced across the sky just below the North Star. "He should be back tomorrow for sure." Seventeen-year-old Johnny Least-Weasel knows that his grandfather Albert is a stubborn old man and won't stop checking his own traplines even though other men his age stopped doing so years ago. But Albert Least-Weasel has been running traplines in the Alaskan wilderness alone for the past sixty years. Nothing has ever gone wrong on the trail he knows so well. When Albert doesn't come back from checking his traps, with the temperature steadily plummeting, Johnny must decide quickly whether to trust his grandfather or his own instincts. Written in alternating chapters that relate the parallel stories of Johnny and his grandfather, John Smelcer's The Trap poignantly addresses the hardships of life in the far north, suggesting that the most dangerous traps need not be made of steel.

Book Description
A Nature Book of the Year (The Times (UK)) “The hoverflies are only props. No, not only, but to some extent. Here and there, my story is about something else.” A mesmerizing memoir of extraordinary brilliance by an entomologist, The Fly Trap chronicles Fredrik Sjöberg’s life collecting hoverflies on a remote island in Sweden. Warm and humorous, self-deprecating and contemplative, and a major best seller in its native country, The Fly Trap is a meditation on the unexpected beauty of small things and an exploration of the history of entomology itself. What drives the obsessive curiosity of collectors to catalog their finds? What is the importance of the hoverfly? As confounded by his unusual vocation as anyone, Sjöberg reflects on a range of ideas—the passage of time, art, lost loves—drawing on sources as disparate as D. H. Lawrence and the fascinating and nearly forgotten naturalist René Edmond Malaise. From the wilderness of Kamchatka to the loneliness of the Swedish isle he calls home, Sjöberg revels in the wonder of the natural world and leaves behind a trail of memorable images and stories.

Book Description
The authors offer unique insights into the factors that make us susceptible to dietary and lifestyle excesses, and present ways to restore the biological processes designed by nature to keep us running at maximum efficiency and vitality. A wake-up call to even the most health conscious people, The Pleasure Trap boldy challenges conventional wisdom about sickness and unhappiness in today's contemporary culture, and offers groundbreaking solutions for achieving change. Authors Douglas Lisel, Ph.D., and Alan Goldhamer, D.C., provide a fascinating new perspective on how modern life can turn so many smart, savvy people into the unwitting saboteurs of their own well-being. Inspired by stunning original research, comprehensive clinical studies, and their successes with thousands of patients, the authors construct a new paradigm for the psychology of health, offering fresh hope for anyone stuck in a self-destructive rut. Integrating principals of evolutionary biology with trailblazing, proactive strategies for well

Book Description
We live in a world of crowds and corporations, artworks and artifacts, legislatures and languages, money and markets. These are all social objects - they are made, at least in part, by people and by communities. But what exactly are these things? How are they made, and what is the role of people in making them? In The Ant Trap, Brian Epstein rewrites our understanding of the nature of the social world and the foundations of the social sciences. Epstein explains and challenges the three prevailing traditions about how the social world is made. One tradition takes the social world to be built out of people, much as traffic is built out of cars. A second tradition also takes people to be the building blocks of the social world, but focuses on thoughts and attitudes we have toward one another. And a third tradition takes the social world to be a collective projection onto the physical world. Epstein shows that these share critical flaws. Most fundamentally, all three traditions overestimate the role of people in building the social world: they are overly anthropocentric. Epstein starts from scratch, bringing the resources of contemporary metaphysics to bear. In the place of traditional theories, he introduces a model based on a new distinction between the grounds and the anchors of social facts. Epstein illustrates the model with a study of the nature of law, and shows how to interpret the prevailing traditions about the social world. Then he turns to social groups, and to what it means for a group to take an action or have an intention. Contrary to the overwhelming consensus, these often depend on more than the actions and intentions of group members.
