the sources, technologies, and tradeoffs involved in meeting the world's energy needs. A historical, scientific, and technical background set the stage for discussions on a wide range of energy sources, including conventional fossil fuels like oil, gas, and coal, as well as emerging renewable sources like solar, wind, geothermal, and biofuels. Readers will learn that there are no truly "green" energy sources―all energy usage involves some tradeoffs―and will understand these tradeoffs and other issues involved in using each energy source.Each potential energy source includes discussions of tradeoffs in economics, environmental, and policy implicationsExamples and cases of implementing each technology are included throughout the bookTechnical discussions are supported with equations, graphs, and tablesIncludes discussions of carbon capture and sequestration as emerging technologies to manage carbon dioxide emission
Formation and activity of the Ukrainian diaspora in New Zealand (1949–2013)
No full textThe article presents the history of formation and development of the Ukrainian community in New Zealand in the period from 1949 to 2013 – from the beginning of Ukrainian immigration to the commencement of significant socio-political changes in Ukraine and Russian aggression, which signifies the beginning of a new stage of the Ukrainian diaspora. The purpose of the investigation is to analyse the historical factors of unification and activity of the Ukrainian community in the country in 1949-2013, as well as the impact of the global migration process. The scientific novelty of the study is that this is the first attempt at a comprehensive examination of the problem, as well as the introduction into scientific circulation of a number of documents and materials on the history of Ukrainians in New Zealand.
Based on the use of interdisciplinary and systematic approaches, general scientific methods of analysis, synthesis, comparison, analogy and historical-typological methods, the main stages of Ukrainian immigration to New Zealand are identified and the features of self-organisation during each phase are traced. The reasons for immigration are determined by objective and subjective factors, attention is focused on the consequences of World War II, as a prerequisite for the beginning of Ukrainian immigration to New Zealand, as well as changes in socio-political and economic circumstances in Ukraine and the world with the collapse of the Soviet Union.
The author concludes that the formation of the Ukrainian community in New Zealand, its consolidation and direction of activities was mainly situational under the influence of various factors – the global migration process, resettlement and employment, family and other circumstances. Simultaneously, with Ukraine gaining independence and the replenishment of the Ukrainian diaspora in New Zealand with new members from Ukraine and the United States, it was reunited around cultural and social work, intensifying cooperation with global Ukrainians and the historical homeland in the interests of the latter

Investigation of polymer and surfactant-polymer injections in South Slattery Minnelusa Reservoir, Wyoming
No full textThis paper presents an investigation of the enhanced oil recovery (EOR) potential in the South Slattery Minnelusa formation. The South Slattery Field, which is characterized by low permeability and high saline brine, is stepping into the economic limits of secondary waterflood. A chemical flooding simulation model which was based on experimental parameters was set up for the potential investigation of EOR. Both polymer and surfactant-polymer floods were investigated. The recoveries of these EOR methods are presented, and the development efficiencies are analyzed. © 2011 The Author(s)
