Space junk crashing into Earth is a real and escalating danger. Milne provides the first synthesis of the interdisciplinary work of the scientific community, which has been investigating how the satellite industry can be protected from manmade and natural space hazards. The result is an invaluable book for those concerned with space missions and space disasters, those worried about cosmic radiation and its effects on humans, members of the Spaceguard defense movement, and anyone concerned with defense and international cooperation efforts in general. Tens of millions of objects may exist in space, ranging in size from grains of sand to entire rocket boosters. Many fireballs seen in the skies, often thought to be UFOs, are in fact manmade debris. Plutonium and other highly toxic fuels from failed Russian craft have already contaminated inhabited areas of Central Asia. Natural hazards such as comet particles can travel at 100 times the speed of a bullet and can severely damage satellites. There is also the danger of spaceweather effects, such as cosmic rays, that could interfere with a spacecraft's electronics and interrupt the global transmission of telephones and television.

ES: Al introducir brevemente el estado de situación socioecológico actual que ha derivado en la propuesta de la época del Antropoceno, pero también de otras conceptualizaciones como la del cambio ambiental global y las fronteras (ecológicas) planetarias, se revisan los alcances y limitaciones teórico-conceptuales de la idea del Antropoceno. Posteriormente, se ofrece una lectura crítica de los retos que trae consigo la expansión del espacio urbano bajo la lógica del capital, ello en tanto configuración principal del espacio en la denominada época del Antropoceno. En ese sentido y desde una lectura crítica, propia de la geografía política urbana y la ecología política urbana, se discute entorno al carácter especulativo de la producción contemporánea del espacio urbano y sus principales implicaciones socioecológicas, mismas que se expresan de manera desigual. Se concluye con una reflexión en torno a las características básicas de una eventual transición urbana hacia modalidades ambientalmente menos devastadoras y socialmente más justas e incluyentes. EN: By introducing the current socio-ecological state that has led to the proposal of the Anthropocene epoch, but also to other conceptualizations such as the global environmental change and the (ecological) planetary boundaries, this paper briefly analyses the theoretical-conceptual scope and limitations of the idea of the Anthropocene. It continues with a critical reading of the challenges that the expansion of urban space brings with it under the logic of capital accumulation; indeed, the main configuration of space under the so-called Anthropocene epoch. The speculative character of contemporary production of urban space and its main socioecological implications, which take place in an uneven manner, are thus discussed from a critical perspective of urban political geography and urban political ecology. The paper concludes with a deliberation on the basic characteristics of an eventual urban transition towards environmentally less devastating and socially fairer ...

Geographies of children and young people is a rapidly emerging sub-discipline within human geography. There is now a critical mass of established academic work, key names within academia, growing numbers of graduate students and expanding numbers of university level taught courses. There are also professional training programmes at national scales and in international contexts that work specifically with children and young people. In addition to a productive journal of Children's Geographies, there's a range of monographs, textbooks and edited collections focusing on children and young people published by all the major academic presses then there is a substantive body of work on younger people within human geography and active authors and researchers working within international contexts to warrant a specific Major Reference Work on children's and young people's geographies. The volumes and sections are structured by themes, which then reflect the broader geographical locations of the research

Two procedures dealing with distance estimation in space are analyzed. In one, formulae relating angular subtense to target distance are derived for spherical and disk objects. A design for a simple reticle to be used in distance estimation is described. In the other procedure, the utilization of illuminance from spherical and disk-shaped satellites for the purpose of relating it to object distance is examined. Formulae describing the relationships for certain cases are developed. The appearance of spherical satellites when illuminated by sources of both small and large angular subtense is dealt with in some detail.

"The aim of this book is not to compile a set of guidelines with systematic discipline, nor to act as a manual to be added to the already numerous publications on the design of Healing Gardens, rather it has attempted to extract - from experiences, projects and research - some principles aimed at highlighting the contribution offered by designers in treating, with equal dignity and equal purpose, the outdoor spaces as interior spaces in healthcare facilities." - Romano Del Nord, Director of TESIS, Inter-University Research Center "Systems and Technologies for Healthcare Buildings", Florence, Italy. "The book provides a narrative summary for urban planners and designers and, especially, health policy-makers and demonstration that consideration of health becomes an element of high importance in city planning. Presented findings of the relationship between physical and social dimensions of urban spaces and their association with health protection sought to pull together clear relevance public outdoor spaces have for public health and to encompass the wider social and economic determinants of public health." - Vladan Đokić, Dean of the Faculty of Architecture, University of Belgrade, Serbia
