Available in PDF, EPUB and Kindle. Book excerpt: This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.

Download or read book Multivariate Analysis of Ecological Data with ade4 written by Jean Thioulouse and published by Springer. This book was released on 2018-11-08 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the ade4 package for R which provides multivariate methods for the analysis of ecological data. It is implemented around the mathematical concept of the duality diagram, and provides a unified framework for multivariate analysis. The authors offer a detailed presentation of the theoretical framework of the duality diagram and also of its application to real-world ecological problems. These two goals may seem contradictory, as they concern two separate groups of scientists, namely statisticians and ecologists. However, statistical ecology has become a scientific discipline of its own, and the good use of multivariate data analysis methods by ecologists implies a fair knowledge of the mathematical properties of these methods. The organization of the book is based on ecological questions, but these questions correspond to particular classes of data analysis methods. The first chapters present both usual and multiway data analysis methods. Further chapters are dedicated for example to the analysis of spatial data, of phylogenetic structures, and of biodiversity patterns. One chapter deals with multivariate data analysis graphs. In each chapter, the basic mathematical definitions of the methods and the outputs of the R functions available in ade4 are detailed in two different boxes. The text of the book itself can be read independently from these boxes. Thus the book offers the opportunity to find information about the ecological situation from which a question raises alongside the mathematical properties of methods that can be applied to answer this question, as well as the details of software outputs. Each example and all the graphs in this book come with executable R code.

This book was released on 2008-07-15 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: John Wesley Powell, U.S. scientist and geographer, put it best when he said that a watershed is: ...that area of land, a bounded hydrologic system, within which all living things are inextricably linked by their common water course and where, as humans settled, simple logic demanded that they become part of a community. Watersheds come in all shapes and sizes. They cross sectorial boundaries (e.g. county, state/province, and country). No matter where you are, you are in a watershed! World-wide, watersheds supply drinking water, provide r- reation and respite, and sustain life. Watersheds are rich in natural capital, producing goods (agriculture and fisheries products) and services (industry and technology) for broad geographic areas. In many countries, at the base of watersheds where tributaries empty into large water-bodies (e.g. estuaries, seas, oceans) are centers of society and are typically densely populated areas. These areas serve as concentrated centers of the socio-economic system. They also are centers of domestic and international trade, tourism, and c- merce as well as the center of governments (capitals) where local, regional and national legislatures are located. As we all live in a watershed, our individual actions can directly affect it. The cumulative effects of all the individual actions of everyone within a watershed may be, and often are devastating to the quality of water resources and affect the health of living things including humans. Therefore, watershed systems are highly subject to threat to human security and peace.

Download or read book Inclusive Development and Multilevel Transboundary Water Governance The Kabul River written by Shakeel Hayat and published by CRC Press. This book was released on 2020-03-11 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: The four decades long ideological-based insurgencies and conflict in the Kabul River Basin (KRB) have seriously hampered the relations and foreign policies of both Afghanistan and Pakistan. Consequently, it restricts them to solve various bilateral issues including transboundary waters. This lack of cooperation over shared water resources is one of the barriers to achieve inclusive and sustainable development. Additionally, it has contributed to the prevailing anarchic situation where each country does what it wants. The absence of a formal water-sharing mechanism coupled with poor water management practices within both the riparian counties are resulting various flow and administration-related challenges. Moreover, these challenges are further exacerbated by regional changes in social, political, environmental and economic systems. The scholarly literature suggests that an analytical transboundary water governance framework is essential to address the challenges of water politicisation and securitisation, quality degradation and quantity reduction. Additionally, the literature rarely integrates (a) a multi-level approach, (b) an institutional approach (c) an inclusive development approach, or (d) accounts for the uses of different types of water and their varied ecosystem services for improved transboundary water governance. To enhance human wellbeing and achieve inclusive and sustainable development in the KRB this research indicates that it is essential to: (1) defrost frozen collaboration; (2) bypass border dispute; (3) use biodiversity and ecosystem services approach; (4) address existing and potential natural and anthropogenic challenges; (5) remove contradictions in the policy environment; (6) combat resource limits and dependence by promoting collaboration on long-term cost effective solutions; and (7) enhance knowledge and dialogue on inclusive development.
