An Environmental History of Russia

The former Soviet empire spanned eleven time zones and contained half the world's forests; vast deposits of oil, gas and coal; various ores; major rivers such as the Volga, Don and Angara; and extensive biodiversity. These resources and animals, as well as the people who lived in the former Soviet Union – Slavs, Armenians, Georgians, Azeris, Kazakhs and Tajiks, indigenous Nenets and Chukchi – were

Glycoside hydrolases from extremophiles isolated in Iceland. alpha-L-Rhamnosidases and pectin degrading enzymes

Extreme environments (high and low temperature, high and low pH, etc.) are inhabited by a vast and diverse flora of microorganisms, which are adapted to these environments (extremophiles). The enzymes produced by extremophiles are active under these harsh conditions and are thus applicable in processes, where conditions are outside the working range of enzymes originating from mesophiles. In this

Selenoproteins in the Bovine Mammary Gland. Regulation of mRNA and Protein Expression

Popular Abstract in Swedish Selen är ett essentiellt näringsämne som behövs för att upprätthålla flera viktiga funktioner i kroppen, huvudsakligen genom en speciell grupp proteiner som heter selenoproteiner. Det finns minst 25 stycken olika selenoproteiner i människan och flera av dem skyddar kroppen mot oxidation medan vissa andra sköter regleringen av sköldkörtelhormoner. Många selenoproteiners Selenium is a micronutrient that is essential for many important life processes due to the action of the specific selenoproteins containing one or more of the 21st amino acid, selenocysteine. Twenty-five selenoprotein genes have been found in the human genome but the function of many of them is not yet known. Some of the characterised selenoproteins have, however, antioxidant properties. Selenium

Dynamic Description with Computer Supported Pictures

A methodology was developed and tested in six case studies at four medium-sized manufacturing companies within the machine engineering industry. Existing and planned work environments and production processes were described with the aid of computer-generated pictures. The pictures were used within the framework of an action research methodology in which managers and those employees affected, toget

Bio-propane from glycerol for biogas addition

In this report, the technical and economical feasibility to produce higher alkanes from bio-glycerol has been investigated. The main purpose of producing this kind of chemicals would be to replace the fossil LPG used in upgraded biogas production. When producing biogas and exporting it to the natural gas grid, the Wobbe index and heating value does not match the existing natural gas. Therefore, th

Practical approaches to channel estimation and interference suppression for OFDM based UWB communications

Ultra-wideband (UWB) communication is a potential technique for future high-speed networks. In this paper, we investigate low complexity signal detection approaches for OFDM based UWB systems. In particular, we develop practical approaches for channel estimation and interference suppression. Computer simulation results show that these techniques can be effectively used in OFDM based UWB systems fo

On Managing Disruption Risks in the Supply Chain - the DRISC model

Popular Abstract in Swedish BAKGRUND Fokus riktas allt mer mot försörjningskedjan och allt mindre mot det enskilda företaget i takt med att konkurrens mellan enskilda företag ersätts av konkurrens mellan försörjningskedjor. Det är emellertid endast det enskilda företaget som kan fatta beslut och vidta åtgärder, men dessa beslut och åtgärder måste idag ske utifrån ett kedjeperspektiv. Med ökat foBackground Today's modern, industrialized society is based on globalization, specialization and mass-production. It is a society dependent upon highly integrated, continuously ongoing supply chain flows. Disruptions in those flows may cause devastating negative consequences, both for the individual company, for the supply chain, and for the society at large. Purpose and objectives The purpose o
