Un libro que repasa la historia del pensamiento positivo, que explora los ingredientes que forjan nuestro temperamento y que nos describe el optimismo no como un ejercicio mental o intelectual, sino como una fuerza que nos permite conquistar metas, resistir la desgracia, vencer la enfermedad y relacionarnos con los dem�s. ENGLISH DESCRIPTION Defeat pessimism and increase your potential to live a healthy and happy life. In this work, psychiatrist Luis Rojas Marcos reviews the history of positive thinking, details the ingredients that distinguish an optimistic disposition from a pessimistic one, and explores the forces that shape our temperament (genetic baggage, character traits, and cultural imprints). He describes proven strategies to promote optimism and examines its impact on our relationship with others, our health and our career, as well as its most valuable quality: its power to help us face life's biggest adversities.

The Government and authorities in Brazil were faced with a tragic accident in Goiânia resulting from the misuse of a strongly radioactive medical teletherapy source not under radiation protection surveillance. The present report is divided into four parts: a chronology of destruction of the source, discovery of the accident and initial response; a description of the human consequences and the dosimetry and treatment of seriously exposed and contaminated persons; an account of the assessment of the environmental contamination and the remedial actions taken; and observations and recommendations. Appendices and annexes give an assessment of the effectiveness of international co-operation in the emergency response, and provide further information on: public communications; radiological survey equipment; guidelines for the discharge of patients; radiological protection; chemical decontamination; and the lessons learned.

"Perspectives on Personality describes a range of viewpoints that are used by personality psychologists today, and helps students understand how these viewpoints can be applied to their own lives. Authors Charles Carver and Michael Scheier dedicate a chapter to each major perspective, presenting an overview on the perspective's orienting assumptions and core themes and concluding with a discussion of problems within that theoretical viewpoint and predictions about its future prospects. The Eighth edition incorporates several important recent developments in the field, including genetics and genomics and the biological underpinnings of impulsiveness"--Back cover

Plant proteases are involved in most aspects of plant physiology and development, playing key roles in the generation of signaling molecules and as regulators of essential cellular processes such as cell division and metabolism. They take part in important pathways like protein turnover by the degradation of misfolded proteins and the ubiquitin-proteasome pathway, and they are responsible for post-translational modifications of proteins by proteolysis at highly specific sites. Proteases are also implicated in a great variety of environmentally controlled processes, including mobilization of storage proteins during seed germination, development of seedlings, senescence, programmed cell death and defense mechanisms against pests and pathogens. However, in spite of their importance, little is known about the functions and mode of actions of specific plant proteases. This Research Topic collects contributions covering diverse aspects of plant proteases research.
