ELEMENTOS BÁSICOS DE QUÍMICA ORGÁNICA Y SU RELACIÓN CON LA BIOSFERA
Los seres vivos estamos formados por moléculas orgánicas, proteínas, ácidos nucleicos, azúcares y grasas. Todos ellos son compuestos cuya base principal es el carbono. Los productos orgánicos están presentes en todos los aspectos de nuestra vida: la ropa que vestimos, los jabones, champús, desodorantes, medicinas, perfumes, utensilios de cocina, la comida, etc.
ELEMENTOS QUÍMICOS Y SUS EFECTOS EN LA NATURALEZA
La química es el origen de la vida. Según la teoría más aceptada sobre el origen de la vida en la tierra, ésta surgió a partir de reacciones químicas hace miles de millones de años que dieron lugar a los primeros compuestos orgánicos a partir de compuestos inorgánicos, actualmente el gran problema que tenemos es conservar precisamente esa vida en el planeta, con este texto pretendemos contribuir a la comprensión de los efectos que algunos elementos químicos producen a la naturaleza y por ende el medio ambiente, para ir creando una cultura ambientalista en nuestros lectores.
Enabling the Business of Agriculture 2019
Enabling the Business of Agriculture 2019 presents indicators that measure the laws, regulations and bureaucratic processes that affect farmers in 101 countries. The study covers eight thematic areas: supplying seed, registering fertilizer, securing water, registering machinery, sustaining livestock, protecting plant health, trading food and accessing finance. The report highlights global best performers and countries that made the most significant regulatory improvements in support of farmers.
Enabling the Business of Agriculture 2017
Enabling the Business of Agriculture 2017, the third report in the series, offers insights into how laws and regulations affect private sector development for agribusinesses, including producer organizations and other agricultural entrepreneurs. Globally comparable data and scored indicators encourage regulations that ensure the safety and quality of agricultural inputs, goods and services but are not too costly or burdensome. The goal is to facilitate the operation of agribusinesses and allow them to thrive in a socially and environmentally responsible way, enabling them to provide essential agricultural inputs and services to farmers that could increase their productivity and profits. Regional, income-group and country-specific trends and data observations are presented for 62 countries and across 12 topics: seed, fertilizer, machinery, finance, markets, transport, water, ICT, land, livestock, environmental sustainability and gender. Data are current as of June 30, 2016. For more information, please see http://eba.worldbank.org
Assets, Livelihoods, and Social Policy
Given the lack of adequate universal social welfare for those unable to find jobs in the salaried formal sector, the livelihoods and well-being of most poor people depends heavily on their asset base. This includes their ability to access and accumulate assets, obtain decent returns from these assets, and use their asset base to manage risks. 'Assets, Livelihoods, and Social Policy' discusses the diverse strategies adopted by people in different contexts to accumulate assets through migration, housing investments, natural resources management, and informal businesses. An asset-based social policy can strengthen asset accumulation strategies as well as help the poor overcome the constraints o...
Post-Fire Management and Restoration of Southern European Forests
In spite of all the efforts made in fire prevention and suppression, every year about 45 000 forest fires occur in Europe, burning ca. 0.5 million hectares of forests and other rural lands. The management of these burned forests has been given much less attention than fire prevention or fire suppression issues, but the post-fire management of burned areas raises strong concerns (economic and social impacts, soil erosion and water quality, biodiversity loss, forest restoration). Although there are a few publications which address post-fire management, the focus of these has been either on general approaches to restoration or specific topics such as preventing post-fire soil erosion. This book is about the post-fire management of fire-prone forest types in southern Europe. It provides the first comprehensive overview of the topic, ranging from stand-level to landscape-level management, and from emergency actions to long-term restoration approaches.
Body Parts and Bodies Whole
This volume grew out of an interdisciplinary discussion held in the context of the Leverhulme-funded project 'Changing Beliefs in the Human Body', through which the image of the body in pieces soon emerged as a potent site of attitudes about the body and associated practices in many periods. Archaeologists routinely encounter parts of human and animal bodies in their excavations. Such fragmentary evidence has often been created through accidental damage and the passage of time - nevertheless, it can also signify a deliberate and meaningful act of fragmentation. As a fragment, a part may acquire a distinct meaning through its enchained relationship to the whole or alternatively it may be used...
Managing Forest Ecosystems: The Challenge of Climate Change
Climate changes, particularly warming trends, have been recorded around the globe. For many countries, these changes in climate have become evident through insect epidemics (e.g., Mountain Pine Beetle epidemic in Western Canada, bark beetle in secondary spruce forests in Central Europe), water shortages and intense forest fires in the Mediterranean countries (e.g., 2005 droughts in Spain), and unusual storm activities (e.g., the 2004 South-East Asia Tsunami). Climate changes are expected to impact vegetation as manifested by changes in vegetation extent, migration of species, tree species composition, growth rates, and mortality. The International Panel on Climate Change (IPCC) has included ...
Buyology
NEW YORK TIMES BESTSELLER • “A fascinating look at how consumers perceive logos, ads, commercials, brands, and products.”—Time How much do we know about why we buy? What truly influences our decisions in today’s message-cluttered world? In Buyology, Martin Lindstrom presents the astonishing findings from his groundbreaking three-year, seven-million-dollar neuromarketing study—a cutting-edge experiment that peered inside the brains of 2,000 volunteers from all around the world as they encountered various ads, logos, commercials, brands, and products. His startling results shatter much of what we have long believed about what captures our interest—and drives us to buy. Among the questions he explores: • Does sex actually sell? • Does subliminal advertising still surround us? • Can “cool” brands trigger our mating instincts? • Can our other senses—smell, touch, and sound—be aroused when we see a product? Buyology is a fascinating and shocking journey into the mind of today's consumer that will captivate anyone who's been seduced—or turned off—by marketers' relentless attempts to win our loyalty, our money, and our minds.
