  • Hydrogen and fuel cells are seen by many as key solutions for the 21st century, enabling clean efficient production of power and heat from a range of primary energy sources. The High Level Group for Hydrogen and Fuel Cells Technologies was initiated in October 2002 by the Vice President of the European Commission, Loyola de Palacio, Commissioner for Energy and Transport, and Mr Philippe Busquin, Commissioner for Research.

  • Graft Failure While complete and sustained engraftment is usually seen posttransplant, occasionally marrow function either does not return or, after a brief period of engraftment, is lost. Graft failure after autologous transplantation can be the result of inadequate numbers of stem cells being transplanted, damage during ex vivo treatment or storage, or exposure of the patient to myelotoxic agents posttransplant. Infections with cytomegalovirus (CMV) or human herpes virus type 6 have also been associated with loss of marrow function.

  • When molecules are present in small numbers, such as is frequently the case in cells, the usual assumptions leading to differential rate equations are invalid and it is necessary to use a stochastic description which takes into account the randomness of reactive encounters in solution.

  • When will the oil run out? Various estimates put this anywhere from 20 years from now to more than a century in the future. The shortfall in energy might eventually be made up by developments in nuclear fusion, fuel cells, and solar technologies, but what can substitute for gasoline and diesel in all the internal combustion enginepowered vehicles that will continue to be built worldwide until then? And what will stand in for petrochemicals as sources of building blocks for the extensive range of “synthetics” that became indispensable during the twentieth century?...

  • Food can be defined as the nutritive material taken into an organism for growth, work, or repair and for maintaining the vital processes. Food sustains life, and, as such, many individuals view food as an uncomplicated, pure source of nutrition. Therefore, such individuals are often bewildered to learn that food is comprised of an array of natural chemicals, and not all the chemicals are nutrients or enhance nutritive value, but in fact may decrease nutritional value or, worse still, are toxic (e.g., naturally occurring toxicants).

  • These CNVs may show association with certain clinical conditions and help in predicting risk and also diagnosis. All these approaches have their merits and demerits and in general are tedious, time consuming and need manpower with stringent handling. This naturally prompted the development of several automated methods for culturing cells in mass scale, use of membrane bioreactors, and image analysis for interpreting the cytogenetic observations made.

  • Finance is all about the systems, institutions and instruments involved in the transfer of funds between individuals, businesses and governments. This includes vital, short-run decisions such as cash management and credit policy, which affect the survival of an organisation, as well as long-term decisions such as investment in plant and equipment, fund-raising, and mergers and takeovers, which determine the wealth of stakeholders. Your studies in finance can lead to career opportunities and also provide useful personal money management strategies.

  • In order to ensure their own leadership capability, sustainability, supportability, mobility, or survivability, modern armed forces are becoming increasingly dependent upon having a reliable supply of electrical energy. Consequently, electrochemical power sources are becoming increasingly important as a means to guarantee this reliable power supply. As this concerns quite a broad field of applications, the potential solutions using electrochemical power sources are also quite different. This article focuses on one specific sector, that of portable applications. ...

  • Discussions about the future of transportation are marked by three key factors À growing energy demand and energy security on the one side and climate change and environmental protection on the other. The word that is most often used to embody all these concerns is ‘sustainability’ or, in the field of transportation, ‘sustainable mobility’. Achieving sustainable mobility is the big challenge for the future in the vehicle and associated industries. It is now common wisdom that transport based on fossil resources is a finite proposition.

  • Human embryonic stem cell (hESC) lines, like those from other species, are pluripotent cell lines derived from the inner cell mass (ICM) of the developing embryo. Due to their exceptional capability of proliferating indefi nitely as undifferentiated cells when cultured in appropriate conditions, and of sustaining a normal karyotype, hESCs may have broad applications for industrial uses; clinical purposes, namely, cell-based therapy; and research of early human development, differentiation mechanisms, and lineage commitment.

  • Several hematopoietic growth factors (HGFs) have achieved widespread clinical application. In the United States alone, more than US $5 billion per year of the health care budget is spent on these factors. The first patients were treated with recombinant human erythropoietin (rHuEPO, epoetin alfa, Epogen®) in 1985 and the first patients received recombinant methionyl human granulocyte colony-stimulating factor (r-metHuG-CSF, filgrastim, Neupogen®) or recombinant human granulocyte-macrophage colonystimulating factor (rHuGM-CSF, sargramostim, Leukine® or Prokine®) in 1986.

  • In 1992, the first United Nations Conference on Sustainable Development, popularly known as the Rio Earth Summit, was convened in Rio de Janeiro, Brazil to address the state of the environment and sustainable development. The Earth Summit yielded several important agreements including “Agenda 21”, a plan of action adopted by over 178 governments to address human impacts on the environment at local, national and global levels, and key treaties on climate change, desertification and biodiversity.
