On January 7, 2007 Evgueni Yakovlevich Khruslov, a prominent mathematician, Academician of the National Academy of Science of Ukraine, celebrated his 70th birthday. Evgueni Khruslov was born in Kharkov, Ukraine. In 1954 he graduated from a high school at a city’s suburb. When studying at the school, he preferred exact sciences, like physics and mathematics. However, at the time of graduation, h...
American book publishing during the Second World War had to cope with a huge increase in demand for books coupled with scarcity of resources, especially paper rationing imposed by the War Production Board. Based on research in the Random House archives and focusing on the Modern Library series, this article examines how publishers coped with wartime challenges and opportunities. Random House gr...
After the Civil War wages fell in the South relative to the non-South, but interest rates and othermeasures of the costs of capital increased.Using archival data formanufacturing establishments, we show that capital–output and capital–labor ratios in southernmanufacturing declined relative to non-southern manufacturing after the War, precisely in the direction implied by the regional shifts in ...
The purpose of this paper is to outline the leading role the Electrical Engineering Department at Manchester played in the early development of control engineering teaching and research in the UK after the war. The holding of a major UK conference in Control Engineering in Manchester roughly 60 years after the start of this work seems an appropriate time to remind today’s researchers of these e...
here, we report analysis of in vitro and in vivo drug release from an in situ formulation consisting of triamcinolone acetonide (tr) and poly(d,l-lactide-co-glycolide) (plga) and the additives glycofurol and hydroxyapatite nanoparticles (ha). we found that these additives enhanced drug release rate. we used the taguchi method to predict optimum formulation variables to minimise the initial burs...
مقدمه: درعلم آمارسنتی همه پارامترها بوسیله مدلهای ریاضی ومشاهده های تجربی تعریف می شد. بعضی وقتها به نظر می رسد چنین فرضهایی برای مسائل زندگی روزمره سختگیرانه باشد.مخصوصا درصورتیکه ما با داده های زبان شناسی یا احتیاجاتی که صریح نباشند سرکارداشته باشیم. برای اینکه این مشکل را ازبین ببریم ازروش فازی استفاده می کنیم. تعریف مسئله: درمرحله اول از تحقیق درباره انواع مختلف از پدیده(زیستی-فنی-فیزیک...
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
from 1950s onward, new theories and critical approaches burgeoned across humanities. these theories were context-oriented; as a result, the analysis of discursive practices gained significance. thus, social, political, historical and cultural discourses that have been hitherto marginalized and considered inferior to literary texts, were introduced as important texts to be analyzed by critics. o...
