We have entered a new era where business, technologies, communities, and even pandemic deceases cross borders with unprecedented speed and intensity. 2030 Agenda and 17 SDGs reflect the global community's high expectations of finally reversing the destruction of our natural and social habits, and achieving a more balanced and equitable pathways toward well-being of all. However, despite the initial efforts, the world is not on track to achieving the most of the 169 targets that comprise the goals. It is evident that we have a system problem, so we need a system solution. Authors presented a hierarchical system consisting of two-level management systems: first level-unsustainability reduction systems and second level-control system for transformations toward sustainability. The book clearly shows that implementation of systems for unsustainability reduction and for transformations toward sustainability is possible, and that sufficient knowledge is available to get started. It is designed for researchers, practitioners, and politicians.

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

The examination of the human fallopian tubes was, until recently, restricted to observations on gross anatomical disposition and tubal patency. These studies, for decades, were the domain of doctors and physiologists whose primary interest was population control and family planning, funded largely by organisations and agencies seek ing alternatives to steroidal contraceptives. For a "worrying" but short period after the birth of Louise Brown in 1978 as the conse quence of successful in-vitro fertilisation and embryo transfer, the fallopian tube was considered to be "dispensable" given that the metabolic milieu in which human fertilisation takes place could be effortlessly reproduced in a Petri dish, in in-vitro fertilisation procedures. However, a number of factors have acted together to renew in terest in the fallopian tube, namely new techniques in cell biology, microinstrument developments (in particular in imaging), an inter disciplinary transfer of skills from interventional radiology and car diology to gynaecology, the surgeon's wish to improve surgical tech niques, and better techniques to monitor early pregnancy. These factors have led surgeons to develop the new diagnostic and ther apeutic strategies and techniques listed here. This volume contains contributions from the majority of keynote speakers at a conference held in London in April 1992 from which its title is derived. Better diagnostic procedures should lead to the implementation of rational effective treatments.

This book constitutes the thoroughly refereed proceedings of the 12th International Conference, Spatial Cognition 2020, held in Riga, Latvia, in September 2020. The physical event was postponed to 2021 due to the COVID-19 pandemic. The 19 full papers and 6 short papers presented in this book were carefully selected and reviewed from 50 submissions. They focus on the following topics: spatial representation and cognitive maps; navigation and wayfinding; spatial representation in language, logic, and narrative; and spatial abilities and learning.

This book treats the topics of preventive innovations and their financing possibilities as an interrelated whole. It provides an in-depth description of cleaner technologies, highlights environmental management accounting and material flow costing as tools for preventive innovation development, and gives an overview of environmental development measures for industry. It aims to raise awareness within financing institutions on financing options of preventive cleaner technologies, a highly debated topic also with options to reduce climate change. The text is supplemented with numerous figures, tables and annexes.
