        Leaving Is a Return

        by A Lai

        “Leaving Is a Return” is the latest collection of essays by writer A Lai. It is divided into four series. The first part is “bronze years”: the meditation and recollection of the hometown. The second part is called “ideal country of vegetation”: a unique understanding of flowers and trees and Rural Movement, in the author's pen, it is an ideal country. The third part is “dust has not fallen”: it is the author's reading notes, as well as the knowledge of literature and reading experience. The fourth part is “music and poetry”: the author's creative experience and writing process and his understanding of many years of writing career. Leaving Is a Return gives us a lot of insights in seemingly ordinary things. The author compares the layers of the mountain to the "staircase" and says "My soul will go to heaven by stepping on these ladders." The author turns his eyes to nature and whispers with the vast world. These beautiful words can let us comprehend the spiritual space of A Lai.

        A History of Pesticides

        by Graham A Matthews

        In this fascinating book, Graham Matthews takes the reader through the history of the development and use of chemicals for control of pests, weeds, and vectors of disease. Prior to 1900 only a few chemicals had been employed as pesticides but in the early 1940s, as the Second World War raged, the insecticide DDT and the herbicide 2-4-D were developed. These changed everything. Since then, farmers have been using a growing list of insecticides, herbicides and fungicides to protect their crops. Their use has undoubtedly led to significant gains in agricultural production and reduction in disease transmission, but also to major problems: health concerns for both users of pesticides and the general public, the emergence of resistance in pest populations, and environmental problems. The book examines the development of legislation designed to control and restrict the use of pesticides, the emergence of Integrated Pest Management (IPM) and the use of biological control agents as part of policy to protect the environment and encourage the sustainable use of pesticides. Finally, the use of new technologies in pest control are discussed including the use of genetic modification, targeted pesticide application and use of drones, alongside basic requirements for IPM such as crop rotations, close seasons and adoption of plant varieties with resistance to pests and diseases.

        Riceland Spiders of South and Southeast Asia

        by A T Barrion, Jim A Litsinger

        Spiders are among the most omnipresent and numerous predators in both agricultural and natural ecosystems, and without them insect pest populations would become out of control. Their potential as biological control agents can only be appreciated through a greater understanding of their abundance and species composition in different ecological systems. There is therefore a great need for literature providing guidance on spider identification. The spider fauna of several cultivated crops, in a number of regions of the world, has been well documented. There have been some previous attempts to record the spider fauna of rice in South and Southeast Asia, but these are scattered in the journal literature. This volume provides a comprehensive illustrated guide that can be used by specialists and novices to identify these spiders. The majority of the species covered were collected from a diversity of habitats in the Philippines. The bulk of the book consists of keys to the identification of families, genera and species of Philippine spiders, illustrated by more than 1000 line drawings and 100 colour photographs. A total of 339 species belonging to 134 genera within 26 families are recognized. Of these, 253 species and seven genera are new to science. Distribution maps for individual species and a classification scheme for Philippine riceland spiders are also provided. Overall, the work represents a major contribution to the literature for those interested in spiders or more generally in biological control and crop protection.

        An Historical Atlas of Staffordshire

        by A. D. M. Phillips, C. B. Phillips

        Within its ancient boundaries, Staffordshire is a county of diverse and contrasting historic landscapes. World-renowned industrial complexes sit alongside agricultural systems; castles rub shoulders with urban-industrial housing; the cathedral centre of a vast diocese lies close to the birthplace of primitive Methodism; overtly planned landscapes mingle with the uplands of the Moorlands and the heathlands of Cannock Chase. These many and varied landscapes are both products and reflections of a multiplicity of histories, and students of the county have been keen to explore and relate these pasts. However, no systematic attempt has previously been made to express these accounts in spatial form. This book seeks to demonstrate by maps the various histories that contribute to the diversity of Staffordshire. With its succinct discussions and detailed map presentations of these themes, incorporating new thinking and recent research, the atlas provides an innovative and major contribution to the study of the history of Staffordshire. ;

        How a Satellite Works

        by Joseph A. Angelo, Jr.

        Designed to help students and teachers better appreciate science and engineering in a global context, this eBook starts with a discussion of the physics of orbiting objects, including the concepts of free fall and microgravity, followed by an explanation of how engineers put a satellite into orbit around Earth. It also describes the basic differences and common components of modern human-made satellites and discusses the growing problem of space debris and the fate of old or broken satellites. A wealth of images help bring the topic to life.

        Asian Citrus Psyllid

        Biology, Ecology and Management of the Huanglongbing Vector

        by Jawwad A. Qureshi, Philip A. Stansly

        Asian citrus psyllid (ACP), Diaphorina citri, is an insect pest which transmits a bacterium, Candidatus liberibacter asiaticus (Clas) through newly emergent foliage of citrus trees. This causes a disease known as Huanglongbing (HLB), which has become the most debilitating and intractable disease in citrus crops. This book, written by a team of experts on the Asian citrus psyllid, gathers together everything currently known about the biology and ecology of this important pest species, examines the transmission and acquisition processes of the pathogen, and looks at current management practices and their effectiveness. The potential for new, innovative management techniques are also described along with the economic implications of managing this rapidly establishing disease.

        The Moon as a Platform for Astronomy and Astrophysics

        by Joseph A. Angelo, Jr.

        The prospect of establishing a permanent lunar base could give scientists the extraordinary ability to use the Moon as a platform for future efforts in space-based astronomy and astrophysics. This eBook introduces a lunar-base development scenario that spans the 21st century and describes several concepts for astronomy performed on the surface of the Moon. As NASA collaborates with commercial and international partners to establish sustainable exploration by 2028, this eBook is an essential read for the scientists of tomorrow.
