Recent research on life in extreme environments has shown that some microorganisms metabolize at extremely low temperatures in Arctic and Antarctic ice and permafrost. Here, we present kinetic data on CO2 and (CO2)-C-14 release from intact and C-14-glucose amended tundra soils (Barrow, Alaska) incubated for up to a year at 0 to -39 degrees C. The rate of CO2 production declined exponentially with
The autonomic nervous system (ANS) and hypothalamic-pituitary-adrenal (HPA) axis are reported as activated in excess in the morbidly obese state and, therefore, changes after weight loss can be anticipated. The aim of this study was to investigate the impact of a massive (similar to30%) weight reduction on the activation of the HPA axis and the ANS following bariatric surgery. Eight (7 women, 1 ma
The interventions of portable digital devices such as mobile telephones, mp3 players, PDAs and many others, have contributed to the formation of contemporary notions of space. The impact of these devices' mobility (informing the users' mobility) could even be paralleled to the shift from the effects of still photography to those of film in the 19th century. Especially important for the perspective
Older people with arrhythmias comprise a large group requiring complex care, posing many healthcare challenges. Rapid growth of the older population demands a better understanding of the needs of this patient group. The aim of this thesis was to investigate arrhythmia prevalence, incidence, survival, and experiences from the perspective of a geriatric population (aged 60+ years), and to examine th
The rat and human recombinant soluble and membrane-bound catechol O-methyltransferase (S- and MB-COMT, respectively) were expressed using mammalian and baculovirus vectors. Low levels of rat and human S-COMT polypeptides were detected by immunoprecipitation in K-562 cell lines transfected with the S-COMT vectors. From K-562 cells transfected with the rat MB-COMT construct, both S- and MB-COMT reco
This work presents an analysis of the physical properties of sub-micrometer aerosol particles measured at the high Arctic site Villum Research Station, Station Nord (VRS), northeast Greenland, between July 2010 and February 2013. The study focuses on particle number concentrations, particle number size distributions and the occurrence of new particle formation (NPF) events and their seasonality in
In the 2011 census of India, more than 2500 settlements have been newly inducted into the category of ‘census towns’ – the lowest size-class of urban settlements in India. This is a staggering figure in light of the observation that a comparable number constituted the total number of all urban settlements recorded since 1900. Furthermore, it has been revealed through aerial images, that a vast maj
OBJECTIVE: Treatments have failed to delay or stop the autoimmune process, preceding onset of type 1 diabetes. We investigated if autoantigen-specific treatment with alum-formulated glutamate decarboxylase (GAD-Alum) was safe and affected progression to type 1 diabetes in children with islet autoimmunity.METHODS: In an investigator-initiated, double-blind, placebo-controlled clinical trial, non-di
Varje år omsätts 900 miljarder kronor i offentliga upphandlingar i Sverige. Dessvärre är det inte endast seriösa leverantörer som försöker vinna dessa kontrakt. På senare år har man i allt större utsträckning uppmärksammat att oseriösa och kriminella entreprenörer också konkurrerar på den offentliga marknaden. Problemet har beskrivits som systemhotande. Upphandlande myndigheter har beskrivits soEvery year, 900 billion SEK is spent on public procurement contracts. Un-fortunately, it is not only serious suppliers which try to win these contracts. In recent years, attention has been drawn to criminal entrepreneurs who compete on the public market. The problem has been described as a threat to the system. Procuring organizations have been described as central to preventing crim-inal entrep
Från förbränning av industri- och hushållsavfall erhålls bland annat restprodukten slagg, vilket är bottenaskan från förbränningen. Varje år skapas stora volymer både i Sverige och i övriga Europa. Den naturliga processen karbonatisering, vilken involverar en reaktion mellan luftens koldioxid och kalcium i materialet, startar då slagg efter förbränning kommer i kontakt med luft. Karbonatiseringen From incineration of industrial- and household waste bottom ash is generated. A large volume of bottom ash is generated yearly in both Sweden and Europe. The natural carbonation process, which involves a reaction between carbon dioxide and calcium in the material, is initiated when the bottom ash reaches contact with air. The carbonation binds carbon dioxide to the bottom ash, decreases the pH and
I juli 2014 föreslog Europakommissionen ett cirkulärt ekonomipaket som skulle bidra till att göra EU mer resurseffektivt genom att recirkulera resurser in i det ekonomiska systemet. En cirkulär ekonomi syftar till att tillvarata värdefulla naturresurser samtidigt som man motverkar behovet av att extrahera nya. Det föreslagna paketet innehöll bland annat ändringar i avfallsdirektiven, höjda återvinIn order to become more resource efficient and circulate resources back into the economic system, the European Commission adapted a circular economy package in 2014. This is in line with the idea of a circular economy. This study investigates how the legislative proposal to review recycling and other waste-related targets in the EU, which was a part of the proposed circular economy package, would
A model is used to describe a system physically or mathematically and to give information about changes in the system variables. Physical knowledge about the system and its quantities can be useful to build a physical model obeying the laws of nature. However, if the system is to be regarded as a black box with only input and output signals, system identification can be used to fit a mathematical
Under de senaste 30 åren har en ny metod för att få information om tidigare ekosystem utveck- lats, nämligen att analysera gammalt (“ancient”) DNA (aDNA). Denna forskningsgren är fortfarande ung men har redan hittat många områden inom vilka den kan tillämpas. Inom paleoekologin finns det två huvudsakliga ändamål med aDNA-analyser; att kartlägga en arts hela genom, samt att bestämma antal taxa och During the last 30 years a new method for obtaining information about past ecosystems has been devel- oped, namely to analyse old (“ancient”) DNA (aDNA). This research field is still young but has already found many areas within which it can be applied. In palaeoecology, there are two main purposes with aDNA analyses; to map the entire genome of a species, and to determine the number of taxa, and

Methodology: The research aims to detect the patterns and understand individual behaviour;therefore, a qualitative approach
17 kap. 10 § LOU stadgar att ett kontrakt eller ramavtal får ändras i enlighet med en ändrings- eller optionsklausul utan att en ny upphandling måste genomföras, om kontraktets eller ramavtalets övergripande karaktär inte ändras, om klausulen har angetts i något av upphandlingsdokumenten och klart, exakt och entydigt beskriver under vilka förutsättningar den kan tillämpas. Vidare ska klausulen äve17th chapter 10th § of the Swedish Public Procurement Act statues that a contract or a framework agreement may be modified without a new procurement procedure in accordance with a review clause or option, if the clause does not provide for modifications that would alter the overall nature of the contract. The review clause shall be set out in the initial procurement documents. Such a clause shall
This master thesis has been conducted to investigate why and how Plastal in Arendal (PAGO), Sweden have implemented RFID technology. RFID technology has become very popular in recent years (1). It is said to have potential to increase the level of automation (2), reduce the labor levels and to improve the supply chain in areas such as inventory, visibility etc. (3) (see chapter 1.2.1 for more exa
Abstract Perforations are one of Tetra Paks oldest inventions of how to open their carton packages. They have been a part of Tetra Briks product portfolio for over 30 years and quality testing is important. Bad openability, with plastic residues covering the torn hole, is a problem that needs to be addressed. When tearing a package with perforation all people do it differently. By using a mechan
Studies of the structural dynamics of solids can improve our understanding of atomic motion in materials, and may thus help in the manufacture of new devices or the development of materials with novel structures and properties. Ultrashort laser pulses, a few tens of femtoseconds long, can deliver high energies (mJ–kJ). This energy is absorbed by the electrons in a solid material, leading to a rapi
Sweden’s Art and Music Schools offer courses and activities after the school day. Besides that, Art and Music Schools also work in collaboration with compulsory schools, including training schools and special schools. The investigation report on Art and Music Schools, part of the national policy process, focuses on the ‘after school’ parts of Art and Music Schools, leaving the other parts untouche
