  • Energy and Training Module ITU Competitive Coach
    37 energy and training module ITU Competitive Coach Produced by the International Triathlon Union, 2007 38 39 energy & training Have you ever wondered why some athletes shoot off the start line while others take a moment to react? Have you every experienced a “burning” sensation in your muscles on the bike? Have athletes ever claimed they could ‘keep going forever!’? All of these situations involve the use of energy in the body. Any activity the body performs requires work and work requires energy. A molecule called ATP (adenosine triphosphate) is the “energy currency” of the body. ATP powers most cellular processes that require energy including muscle contraction required for sport performance. Where does ATP come from and how is it used? ATP is produced by the breakdown of fuel molecules—carbohydrates, fats, and proteins. During physical activity, three different processes work to split ATP molecules, which release energy for muscles to use in contraction, force production, and ultimately sport performance. These processes, or “energy systems”, act as pathways for the production of energy in sport. The intensity and duration of physical activity determines which pathway acts as the dominant fuel source. Immediate energy system Fuel sources ATP Sport E.g. carbohydrates, energy performance proteins, fats “currency” Short term energy system E.g. swimming, cycling, running, transitions Long term energy system During what parts of a triathlon might athletes use powerful, short, bursts of speed? 1 2 What duration, intensity, and type of activities in a triathlon cause muscles to “burn”?

  • Adaptive Equipment and Energy Conservation Techniques During Performance of Activities of Daily Living
    Adaptive Equipment and Energy Conservation Techniques During Performance of Activities of Daily Living Problem: A wide range of diagnosis can affect the performance of activities of daily living (ADLs). The performance of these activities; feeding, dressing, and bathing to name a few are an essential part of our daily lives. An individual’s ability to function in daily activities is often dependent on physical and cognitive health. The use of adaptive equipment and energy conservation techniques can make all the difference in making these important daily tasks possible and effect one’s perception and quality of their life. Adaptive Equipment Adaptive equipment is used to improve functional capabilities. Adaptations can assist someone in their home or out in the community, ranging from longer, thicker handles on brushes and silver wear for making them easier to grasp to a powered wheelchair. Below is a chart including various diagnosis and examples of adaptive equipment that could greatly benefit individuals experiencing similar circumstances.

  • Improving Institutional Access to Financing Incentives for Energy
    Improving Institutional Access to Financing Incentives for Energy Demand Reductions Masters Project: Final Report April 2016 Sponsor Agency: The Ecology Center (Ann Arbor, MI) ​ Student Team: Brian La Shier, Junhong Liang, Chayatach ​ Pasawongse, Gianna Petito, & Whitney Smith Faculty Advisors: Paul Mohai PhD. & Tony Reames PhD. ​ ACKNOWLEDGEMENTS We would like to thank our clients Alexis Blizman and Katy Adams from the Ecology Center. ​ ​ We greatly appreciate their initial efforts in conceptualizing and proposing the project idea, and providing feedback throughout the duration of the project. We would also like to thank our advisors Dr. Paul Mohai and Dr. Tony Reames for providing their expertise, guidance, and support. This Master's Project report submitted in partial fulfillment of the OPUS requirements for the degree of Master of Science, Natural Resources and Environment, University of Michigan. ABSTRACT We developed this project in response to a growing local­level demand for information and guidance on accessing local, state, and federal energy financing programs. Knowledge regarding these programs is currently scattered across independent websites and agencies, making it difficult for a lay user to identify available options for funding energy efficiency efforts. We collaborated with The Ecology Center, an Ann Arbor nonprofit, to develop an information­based tool that would provide tailored recommendations to small businesses and organizations in need of financing to meet their energy efficiency aspirations. The tool was developed for use by The Ecology Center along with an implementation plan to strengthen their outreach to local stakeholders and assist their efforts in reducing Michigan’s energy consumption. We researched and analyzed existing clean energy and energy efficiency policies and financing opportunities available from local, state, federal, and utility entities for institutions in the educational, medical, religious, and multi­family housing sectors.

  • Chapter 1: Energy Challenges September 2015 1 Energy Challenges
    QUADRENNIAL TECHNOLOGY REVIEW AN ASSESSMENT OF ENERGY TECHNOLOGIES AND RESEARCH OPPORTUNITIES Chapter 1: Energy Challenges September 2015 1 Energy Challenges Energy is the Engine of the U.S. Economy Quadrennial Technology Review 1 1 Energy Challenges 1.1 Introduction The United States’ energy system, vast in size and increasingly complex, is the engine of the economy. The national energy enterprise has served us well, driving unprecedented economic growth and prosperity and supporting our national security. The U.S. energy system is entering a period of unprecedented change; new technologies, new requirements, and new vulnerabilities are transforming the system. The challenge is to transition to energy systems and technologies that simultaneously address the nation’s most fundamental needs—energy security, economic competitiveness, and environmental responsibility—while providing better energy services. Emerging advanced energy technologies can do much to address these challenges, but further improvements in cost and performance are important.1 Carefully targeted research, development, demonstration, and deployment (RDD&D) are essential to achieving these improvements and enabling us to meet our nation’s energy objectives. This report, the 2015 Quadrennial Technology Review (QTR 2015), examines science and technology RDD&D opportunities across the entire U.S. energy system. It focuses primarily on technologies with commercialization potential in the mid-term and beyond. It frames various tradeoffs that all energy technologies must balance, across such dimensions as diversity and security of supply, cost, environmental impacts, reliability, land use, and materials use. Finally, it provides data and analysis on RDD&D pathways to assist decision makers as they set priorities, subject to budget constraints, to develop more secure, affordable, and sustainable energy services.

  • The Entropocene
    THE ENTROPOCENE Jeff Robbins Rutgers University 101 Murray Hall, New Brunswick, NJ 08901, USA ABSTRACT According to Eric Schneider and the late James Kay “nature abhors a gradient” as it seeks to degrade any and all differences that can make a difference. They also claim that life self-organized by creating a meta-order out of disordered orders, evolving as an increasingly efficient, effective, sustainable (order from order) means for degrading the huge sun to earth temperature gradient. They inject purpose into the scheme by claiming that life represents “order emerging from disorder in the service of more disorder.” Or, as Jeffrey Wicken succinctly put it in “Evolution and Thermodynamics: The New Paradigm,” “Organisms are remote-from-equilibrium systems that maintain their organizational structures by irreversibly degrading free energy through informed kinetic pathways acquired through evolution. Dissipation through structuring is the strategy of life.” In other words, life came about as an evolving means for giving the Second Law of Thermodynamics what it wants. Entropy. In my 2015 ISSS paper, “Anthropocene as Life’s State of the Art in Disorder Production: A Sustainability Conundrum,” I proposed that our species collectively is disorder producer summa cum laude. We are the most efficient, most effective, degrader of gradients, producer of entropy yet evolved. Calling our epoch, “the Anthropocene” doesn’t capture our essence. Our epoch is the Entropocene. We have turned the bio-geosphere from an accumulator of solar exergy (“free energy”, the measure of energy’s utility) as in fossil fuels, into a trapper of entropy a.k.a., global warming.
