COLD-SAT: A technology satellite for cryogenic experimentation

NASA-Lewis (LeRC) is involved in the development and validation of analytical models which describe the fluid dynamic and thermodynamic processes associated with the storage, acquisition and transfer of subcritical cryogenic fluids in low gravity. Four concurrent studies, including one in-house at LeRC, are underway to determine the feasibility of performing model validation experiments aboard a free-flying spacecraft (S/C) called Cryogenic On-Orbit Liquid Depot-Storage, Acquisition and Transfer (COLD-SAT), using liquid hydrogen as the cryogen. The technology requirements for the experiments are described along with the initial LeRC concepts for the S/C and an experiment subsystem comprising of cryogenic tankage (a supply dewar and three receiver tanks), gas pressurization bottles (both helium and autogenous hydrogen), their associated plumbing, and instrumentation for data collection. Experiments were categorized into enabling/high priority Class 1 technologies and component/system Class 2 demonstrations. As initially envisioned by LeRC, COLD-SAT would have had a 1997 launch aboard a Delta-2 for a 6 month active lifetime in a 925 km orbit with a pseudo-inertial attitude

Smiths Falls in the World: A Study of Globalization in a Rural Canadian Town

In early February, 2007, Hershey’s Chocolate Company announced its global supply-chain transformation plan to cut more than 1500 jobs from its Canadian and United States plants. Smiths Falls, the Chocolate Capital of Canada, lost its Hershey factory together with the closure of the Rideau Regional Centre, an institution for people with developmental disabilities. By the end of 2008, this Eastern Ontario town of roughly 9,000 people shed roughly 1700 jobs, constituting almost 40% of its active labour force (Sutton, 2009). Globalization, despite the confusion generated by the word, must be considered a core factor in the economic and social situation. Smiths Falls confronts these lay-offs from a position of economic and social strain already. The paper examines the broader changes in the world occurring through globalization and how the local society of Smiths Falls has adjusted in tandem. Such an analysis has likely been relevant to Smiths Falls since its inception; as a meeting point of transcontinental trade and a centre of manufacturing within an ever-expanding and more complex supply chain

Analisis Transmisi Harga Jagung sebagai Bahan Pakan Ternak Ayam Ras di Sumatera Barat

The reseacrh was conducted in West Pasaman West Sumatera. There was a phenomenon in the research area that poultry farmers had difficulty to get maize for layer feed and the tendency of price increase of maize after the operation of feed industry. The purpose of the reseacrh were to analyze the elasticity of price transmission between producers and consumers pricing. Method of the research was a quantitative description and statistic analyze to measure elasticity of price transmission between producers and consumers pricing. Data used in the research was secondary data. The result of research revealed that elasticity of price transmission was small (η = 0,26), indicated that the price change at farmer level was lower than consumers level therefore the market of maize in West Sumatera was not efficient

Peran Uni Eropa dalam Proses Penyelesaian Sengketa Bagi Negara Anggota dan Negara Non Anggota

The main reason for the establishment of the first European Union once was because of the desire to provide protection to the European countries that are victims of cruel regimes of Germany during World War II. After the signing of the Maastricht Treaty in 1992, the European Union is increasingly proving its progress to the International community as one of the largest regional organizations. Expand the authority of the European Union in the field of law to be the same as the state. The European Union has a great sovereignty of the member states. Help resolve internal disputes in the European Union has two methods to resolve the internal disputes through alternative and legal means. The purpose of this paper is to look at the mechanism by the European Union as an International organization in its role to resolve disputes in the European Union. As an International Organisation which aims at maintaining world peace and security, the European Union also play the role to help resolve disputes outside the European Union. With the development of increasingly advanced, the European Union as an International organization has the effect of maintaining security and peace in the world, because it is also the European Union, have the opportunity to be able to play non-member countries to resolve disputes, without passing the limits of the sovereignty of a non-member country
