The Losses in the Beef Sector in Canada From BSE

The appearance of BSE in the Canadian beef herd brought immediate financial hardship to the industry due to the immediate closure of export outlets to Canadian beef, live animals and by-products. Nobody knew how long the border would stay closed and many worried that the Canadian beef industry could not survive a prolonged disruption of markets for beef. Previously, producers in Canada had enjoyed secure access to markets for beef around the world, with most of the exports destined for the United States, Mexico, Japan and South Korea. Both federal and provincial governments quickly developed assistance programs and, over the next two years, transferred about $2 billion to various sectors of the beef industry. Government subsidies certainly helped the beef sector but industry representatives argued that it did not cover nearly all the losses that had occurred. This is consistent with the results of this study.Livestock Production/Industries,

The Impact of Trade Barriers on Mandated Biofuel Consumption in Canada

In 2008 the Canadian government passed amendments to the Environmental Protection Act requiring five percent ethanol in transportation fuels sold in Canada by 2010 and two percent renewable content in diesel and heating fuels by 2012. Agricultural commodity and other groups have lobbied for further marketplace intervention that would ensure the biofuel needed to meet the legislated requirement be produced from domestic sources. Indeed, many of these special interests would like the biofuels content increased from five to ten percent and for the increase to be met by domestic firms only. The objective of this study is to compare the relative economic impacts in Canada of achieving a ten percent biofuel content either through increased imports or by substituting domestic production in place of increased imports.biofuel trade policy ethanol canada, Demand and Price Analysis, International Relations/Trade,

Challenges for Water Researchers in Alberta in a Climate of Policy Uncertainty

A safe and plentiful supply of surface water is crucial to the well-being of every resident of Alberta. The effective and efficient use of surface water is central to economic growth and environmental sustainability. As the necessary but competing demands on surface water intensify, the awareness of its limited supply increases. This is particularly evident in southern Alberta, which has experienced significant agricultural, industrial and population growth. In addition to its use for extensive irrigation, surface water in the South Saskatchewan River basin is vital to meet drinking and sanitation needs in rural and urban communities. Management of this key resource involves many researchable issues– water supply, water treatment, water distribution, wastewater collection and processing, flood control, navigation, hydropower production, aquatic recreation – which interact with each other and with government policies. The purpose of this article is to outline the priorities for socio-economic research on surface water resource issues in light of the ever-changing legal and policy frameworks in Alberta.Resource /Energy Economics and Policy,

Interface properties in dielectrics: A cross-section analysis by atomic force microscopy

International audienceEven if interfaces are more and more investigated their properties remain partially unknown, especially as regards their electronic properties. This is mainly related to the lack of characterization at relevant scale. In this context, electrical modes derivate from Atomic Force Microscopy appear well adapted. In this paper, a method to probe space charge at nanoscale is proposed. This method is based on surface potential measurement by Kelvin Probe Force Microscopy (KPFM) and post-processing technique based either on numerical derivation or Finite Element Method. Through these methods, densities of interface charges and injected charges were determined at different metal/dielectric interfaces

Stopping power of hot QCD plasma

The partonic energy loss has been calculated taking both the hard and soft contributions for all the $2 \to 2$ processes, revealing the importance of the individual channels. Cancellation of the intermediate separation scale has been exhibited. Subtleties related to the identical final state partons have properly been taken into account. The estimated collisional loss is compared with its radiative counter part. We show that there exists a critical energy ($E_c$) below which the collisional loss is more than its radiative counterpart. In addition, we present closed form formulas for both the collision probabilities and the stopping power ($dE/dx$)Comment: revised version, section added, 9pages with 5 figure
