  • Mitochondrial calcium overload has been implicated in the irreversible damage of reperfused heart. Accordingly, we studied the effect of an oxy-gen-bridged dinuclear ruthenium amine complex (Ru360 ), which is a select-ive and potent mitochondrial calcium uniporter blocker, on mitochondrial dysfunction and on the matrix free-calcium concentration in mitochondria isolated from reperfused rat hearts.

  • Mechatronics, the synergistic blend of mechanics, electronics, and computer science, has evolved over the past twenty-five years, leading to a novel stage of engineering design. By integrating the best design practices with the most advanced technologies, mechatronics aims at realizing highquality products, guaranteeing, at the same time, a substantial reduction of time and costs of manufacturing.

  • They use geological and distribution data on the island’s 1,284 plant genera and more than 2,000 endemic plant taxa to identify 19 biomes there, and they describe complex conservation challenges. The next chapter by Benny Chan and Pei-Fen Lee explores the biogeography of the barnacles of Taiwan, relating taxon distributions to coastal geomorphology and the complex array of oceanic currents around the island. Global climate changes in ocean water temperature may permit southerly, warmwater taxa to expand northward, invading habitat presently occupied by coldwater taxa....

  • A primary purpose in creating this 3rd Edition is the addition of a stair design component. Over many years as a design studio teacher and critic, I have been regularly reminded of the significant difficulty that many students have in learning to design and draw stairs correctly. From a design perspective, stairs are among the more complex elements within buildings, particularly when there are multiple levels to be accommodated and/or complex building configurations to be considered.

  • The extracellular matrix (ECM) represents a complex organization of macromolecules that surrounds the cell and comprises the substratum onto which the cell may be attached. The properties and functions of the ECM depend ultimately on its structure, molecular components, architecture, and dynamic modulation. Because the critical role of ECM involved in cell biology and physiology has long been recognized, the structure and biology of the ECM have been extensively studied (Yurchenco and Birk 1994 ; Ayad et al. 1998 ; Robert 2001 ) .

  • This book is an expression of gratitude for my incredible good for- tune to be immersed in the world of projects while meeting the teachings of the wisdom traditions of Yoga, Taoism, Advaita Vedanta and Buddhism. From these teachings and their application in complex organizations performing complex projects, I am better able to under- stand the essence of the many attempts to express the nature of our shared experience. I wish to thank first my wife Linda, a fellow traveler and the loving mirror who helps me to see myself as I am and as I can be. Thanks...

  • In the quest for knowledge, it is not uncommon for researchers to push the limits of simulation techniques to the point where they have to be adapted or totally new techniques or approaches become necessary. True multiscale modeling techniques are becoming increasingly necessary given the growing interest in materials and processes on which large-scale properties are dependent or that can be tuned by their low-scale properties. An example would be nanocomposites, where embedded nanostructures completely change the matrix properties due to effects occurring at the atomic level.

  • In approaching this complex subject, it is important to understand where it sits in our social and political order. First, we must recognize that armed conflict is rarely, if ever, solely about religion or religious differences. Although armed conflicts may take on religious overtones, their genesis is found in a complex matrix of crisscrossing and mutually exacerbating factors such as economics, politics, resources, ethnicity and identity, power struggles, inequality, oppression, and other historical grievances.

  • However, as research in this area matures, findings are becoming more complex. Studies by Motteram and Forrester (2005), Fung (2004) and Kear (2004) all show that whilst some students gain support and reassurance from interacting with other students, others place little value on such activities or struggle to find the time to engage in them due to work and family commitments....

  • These are complex, interlinked issues. “Sustainable development” has been proposed as a holistic approach for dealing with these complexities. Sustainable development integrates economic, envi- ronmental and social considerations in order to improve the lives of the current generation and ensure that future generations will have adequate resources and opportunities. Over recent decades, public awareness and concern has grown, as has knowledge of the effects of our activities on the environment.

  • Here follows the continuation of a collection of examples from Calculus 4c-1, Systems of differential systems. The reader is also referred to Calculus 4b and to Complex Functions. We focus in particular on the linear differential equations of second order of variable coefficients, although the amount of examples is far from exhausting. It should no longer be necessary rigourously to use the ADIC-model, described in Calculus 1c and Calculus 2c, because we now assume that the reader can do this himself....
