Intro to EWB: The EWB challenge is devoted improving lives, “Welcome to Engineers Without Borders (EWB) Australia. We 're here to engineer a better world, (Engineers Without Borders Australia, 2016).” The challenge they set before themselves is to allow everyone to lead a life without poverty through engineering knowledge and resources. “We connect, educate and empower people through humanitarian engineering. Humanitarian engineering uses a people centered, strength based approach to improve community health, well being and opportunity, (About Us - Engineers Without Borders Australia, 2016).” They place value on the construction of relationships based on mutual trust and respect and thrive on the sharing of knowledge and culture from both parties. The challenge taken on by the EWB in Zambia with the assistance of the UNHCR, (the United Nations refugee agency) is focused on the Mayukwayukwa refugee settlement in the Kaoma District of Zambia’s Western Province. “The settlement is home to over 11,000 refugees, the majority (over 6,000) of whom have fled the war of liberation in Angola. Other refugees in the settlement come from the Democratic Republic of Congo, Burundi and Rwanda. (UNHCR Zambia | EWB Challenge, 2016).” Thus the EWB has taken the challenge of developing engineering and technological solutions to assist the integration and creation of sustainable livelihoods of the refugees due to pledges by the Government of the Republic of Zambia in 2011 and 2013 allowing the…

1.1 What is a heat engine? In thermodynamics, a heat engine is a device/system that uses heat to do work, i.e. it converts heat or thermal energy to mechanical energy. 1.2 How does a heat engine work and its operating principles? For a heat engine to work, it must operate in cycles. Firstly, heat is added into the system. Let the heat added into the system be represented by [Qh]. After that process, some of the energy that were added into the system will be used to do work e.g the…

Description of the proposed heat release rate model. The cylinder gas is considered as a spatially homogeneous thermodynamic system occupying in a single zone for the compression, expansion, intake, exhaust processes and two zones (burned and unburned zone) for the combustion process. The instantaneous composition of cylinder gases are obtained from the mass fraction of fuel burned. The instantaneous thermodynamic properties are computed by the established equations [20-21, 28]. The…

object; kinetic energy is the rate at which molecules or particles move. When particles of any matter (solids, liquids, gases or elementary plasmas) move faster, they carry more kinetic energy and feel warmer than a material with slower particles. Boiling Boiling is the process where molecules transition from the liquid phase to the gas phase, resulting in the formation of vapour bubbles within the liquid (Figure 1). Figure 1 – Liquid changing to a gas. Boiling Point Boiling point is the…

decreased liquid vaporizes. There are circumstances where both liquid and gas can coexist in equilibrium, these values lie on the vapor-pressure line on a phase diagram. A phase diagram is shown below in Figure 2. Figure 2 There are a few other key terms one should know when discussing phase behavior; Critical pressure is the pressure that above it liquid and gas cannot both exist. Also the Critical Temperature is the point at which gas can no longer be condensed to liquid. In this…

will help any progress in the science . Denying that there is any ambiguity would not serve the scientist’s purpose as a scientist, though maybe it would as a politician. We cannot say that we know what the future holds for us. We have reasons to be uncertain, and reasons to examine these potential threats that exist on the horizon. But most of all, it is important to undertake this scientific endeavor in the name of science, welcoming doubt and distrust as a extremely important tool in the…

Joshua Connolly 08 August 2015 NCAS2015FALL Evolvable Mars Campaign Essay Question # 4 The question of how to effectively plan a mission to Mars is multi-faceted. To convey the idea of the best mission, every portion of the mission must be discussed. The spacecraft must be designed to meet all mission and safety specifications. The testing must recreate possible scenarios encountered for the duration of the mission. The actual spaceflight plan must account for every action the mission is to…

Fiction Belongs in Education Fiction is not real, but it is a real life experience, situation, and story that the reader can relate and learn from. “Fiction, because it is not about someone who actually lived in the real world, always has the possibility about being oneself”(Orson Scott Card). Fiction makes the reader become the main character or actor in a story who goes through and overcomes obstacles that are seen in everyday living and society. As readers we learn from fiction and some use…

Learning About Aging with Mr. F Mr. F was born in the summer of 1927. Some of his earliest memories are of his mother’s stories about strangers putting money in his stroller during the Roaring 20’s. He began his life in a St. Louis suburb but then moved at a young age to a cottage with a barn in the country. His parents are West German. He remembers the cottage being drafty and cold during the winters and it had no bathroom. At school, he was the only child in the first grade. His family moved…

In what ways are we putting Earth under complicated issues? What can we do in order to achieve long lasting sustainability in Earth? Earth has become an issue all throughout the world and has been the number one problem due to the lack of attention we put on it. Many might not consider it an issue because we see the problems everyday thinking it’s normal, however it affects us along with the Earth. This has an impact on the world because we are the ones who come across problems involving the…
