    Enterprising Rural Families (ERFTM) is an international course for the rural family in business. ERFTM teaches a process of finding success, resilience and satisfaction for rural families engaged in enterprises; including agriculture. Instructors from the United States, Canada and Australia have teamed together to offer this course that focuses on the three main components of a family business: individuals, the family unit and the business enterprise. This course also allows families in business to increase their awareness of cultural differences and similarities and improve their understanding of global issues. The course consists of written presentations, online chat sessions, threaded discussions, readings, videos, case studies and individual projects. Using these mechanisms, the online interaction provides rural families with both the tools and skills to resolve immediate family business issues and build a profitable business for the future.Consumer/Household Economics, Farm Management,

    In vitro effect of canine hyperimmune sera on TNFa activity

    [Introduction]: Septic shock in dogs is caused by cardiovascular and vasomotor failure associated with an uncontrolled intrinsic release of inflammatory mediators [1–5]. The syndrome is characterized by cardiovascular dysfunction, vascular permeability alterations, pulmonary oedema and tissue hypoxia resulting from microthrombi which may culminate in disseminated intravascular coagulation and catastrophic multiple organ failure [6,7]. Systemic bacterial infection, particularly by Gram-negative enterobacteria, haemorrhagic trauma, gastric dilation/volvulus and pancreatitis are the major underlying causes leading tosepsis [8,9]. Because of haemodynamic instability and associated hypovolemia, fluid replacement therapy is generally applied to restore effective circulating volume. The use of fresh frozen plasma has been recommended in cases of coagulopathies as it has been recognized to assist restoration of haemodynamic stability [1,5,10,11]. There is increasing evidence that the drivers of the haemodynamic instability are inflammatory mediators (particularly TNFa) activated primarily by bacterial endotoxin [3,4,12,13]

    In situ analysis of solvent/nonsolvent exchange and phase separation processes during the membrane formation of polylactides

    Membrane formation of polylactides has been studied using in situ analysis techniques. An experimental method based on the use of dark ground optics and reflected light illumination is used to monitor the mass transfer and phase separation dynamics during for mation. Additionally, the phase separation and structure formation has been studied using optical microscopy. The results of the dark ground optics technique for the polymer/solvent/nonsolvent systems poly-L-lactide/chloroform/methanol and poly-DL-lactide/chloroform/methanol showed that the diffusion kinetics were similar for the semicrystalline poly-L-lactide (PLLA) and the amorphous poly-DL-lactide. The influence of the molecular weight of the polymers on the diffusion kinetics was found to be negligible. Increasing the polymer concentration of the casting solution decreased the rate of diffusion. The phase separation of poly-DL-lactide was studied with optical microscopy and found to proceed via liquid-liquid demixing. For poly-L-lactide solutions of relatively low concentration (5-6% w/w), phase separation proceeded via liquid-liquid demixing followed by crystallization. For more concentrated PLLA solutions, phase separation proceeded directly via solid-liquid demixing processes. Additionally, for 6% w/w solutions of poly-L-lactide in dioxane immersed in methanol, precipitation also occurred solely via solid-liquid demixing

    Best Practices for Tourism Center Development Along the Red Sea Coast

    The spectacular coastlines along Egypt\u27s Red Sea and Gulf of Aqaba are the focus for one of the fastest growing tourism economies in the world. In order to accomplish national objectives for growth in permanent, well-paying jobs and in foreign exchange earnings, the Tourism Development Authority (TDA) has launched an initiative to make land available to investors for resort development along these coastlines. As of December, 1997, 6,000 hotel rooms are under construction in the Red Sea region and the TDA has proposals for at least 240 major resorts to be built by the year 2020. While this program has begun to yield impressive results in terms of new hotel construction, tourism jobs and tourist visitations, TDA has recognized that priority must be given to guiding private development in ways that protect Egypt\u27s natural heritage and insure that tourism can be sustained far into the future. It is clear from experience to date that such rapid growth, if not carefully planned and managed, threatens the very attractions that bring visitors here. In the best practices described here, TDA defines well planned and managed -- as distinct from haphazard and destructive -- tourism development for the Red Sea coastal environment. We look to lessons gained from several case studies of tourism center sites being jointly planned by TDA and development companies and from studies of successful established tourism centers in Egypt and from other parts of the world. We also draw upon technical literature from a variety of related fields, including marine biology, landscape architecture, engineering, tourism marketing, environmental planning, and others. These lessons and research are distilled into best practices for the planning and siting of new tourism centers and for the use and protection of environmental assets adjacent to the centers including the coral reef ecosystems, the beaches and headlands, the setback areas along coastal waters, and the surrounding desert landscape. This Best Practices Handbook is designed to be practical, well-illustrated and easily understood. It covers aspects of tourism center development that will: assist the development community to achieve environmentally sound, aesthetically pleasing and market-sensitive tourism centers, and assist the TDA and other public agencies by providing benchmarks on which to set environmental policies, guide the location of tourism centers and the subdivision of public lands, judge development plans and proposals, and base environmental management regulations. In the first section, Best Practices focuses on the framework for tourism development and environmental protection: the roles and responsibilities of key groups and the development process. The subsequent section describes the unique physical and environmental context in which tourism development is occurring and the special measures needed to respect these development shaping features. The subsequent sections address the best practices to accomplish sustainable tourism development. The best practices are not presented as a rigid set of prescribed steps and procedures, but rather as guidance and assistance in designing successful tourism facilities and managing the environmental assets on which tourism depends. Furthermore, this should be seen as our first effort. We intend to build upon and refine these practices as wel gain continued experience. Your suggestions for improvement will be sincerely appreciated

    No excess of mitochondrial DNA deletions within muscle in progressive multiple sclerosis

    BACKGROUND: Mitochondrial dysfunction is an established feature of multiple sclerosis (MS). We recently described high levels of mitochondrial DNA (mtDNA) deletions within respiratory enzyme-deficient (lacking mitochondrial respiratory chain complex IV with intact complex II) neurons and choroid plexus epithelial cells in progressive MS. OBJECTIVES: The objective of this paper is to determine whether respiratory enzyme deficiency and mtDNA deletions in MS were in excess of age-related changes within muscle, which, like neurons, are post-mitotic cells that frequently harbour mtDNA deletions with ageing and in disease. METHODS: In progressive MS cases (n=17), known to harbour an excess of mtDNA deletions in the central nervous system (CNS), and controls (n=15), we studied muscle (paraspinal) and explored mitochondria in single fibres. Histochemistry, immunohistochemistry, laser microdissection, real-time polymerase chain reaction (PCR), long-range PCR and sequencing were used to resolve the single muscle fibres. RESULTS: The percentage of respiratory enzyme-deficient muscle fibres, mtDNA deletion level and percentage of muscle fibres harbouring high levels of mtDNA deletions were not significantly different in MS compared with controls. CONCLUSION: Our findings do not provide support to the existence of a diffuse mitochondrial abnormality involving multiple systems in MS. Understanding the cause(s) of the CNS mitochondrial dysfunction in progressive MS remains a research priority
