På dagens arbetsplatser används informations- och kommunikationsverktyg i allt större utsträckning. Användningen har, utifrån vissa aspekter, visat sig inverka negativt på de anställdas arbete och på den interna kommunikationen. Tidigare forskning har berört stress orsakad av informations- och kommunikationsteknologi (IKT) men få studier har gjorts för att studera hur anställda upplever arbetet me
International migration facilitated by contemporary globalization has brought about feelings of insecurity in terms of identity for both the host societies as well as incoming immigrants posing a major obstacle in host countries to integrate immigrants into society. In such context, social exclusion and discrimination can occur. The author argues that this is not a one-directional process. In orde
We report on the application of simultaneous single-shot imaging of CH and OH radicals using planar laser-induced fluorescence (PLIF) to investigate partially permixed turbulent jet flames. Various flames have been stabilized on a coaxial jet flame burner consisting of an outer and an inner tube of diameter 22 and 2.2 mm, respectively. From the outer tube a rich methane/air mixture was supplied at
The thesis considers the effects of electron correlation by studying the two opposite limits of atoms in the ground state and atoms in strong laser pulses. Computational methods and theoretical approaches differ significantly due to the different physical processes that are studied in these two cases. The thesis has an introductory chapter with a brief discussion of the problem of describing elec
The existing Swedish regulation of fire dimensioning regarding structures are separated into two separate parts which isn’t unproblematic. This sets demands for a new regulation based on a holistic view that can reveal how a fire in a compartment can affects the whole building. This compared to the existing demands that only could quantify a certain time limit as a demand in only a single fire cel
Lenodus variabilis occurs in an interval in the lower to middle Kundan Stage which includes the Arenig-Llanvirn boundary. The lower part of its range constitutes the L. variabilis Zone, the upper part, where it co-occurs with Yangtze-placognathus crassus, making up the Y. crassus Zone. The conodont faunas of these two consecutive conodont biozones have been investigated in 14 sections from south,
The plastic carrier bag epitomises many of the features that have transformed plastics into a material that defines our contemporary modern culture. The versatility, durability, strength and low cost have made it into an indispensable companion for consumers. In parallel with plastic becoming an increasingly contested material, the plastic carrier bag has emerged as a controversial object in many
The question posed by this thesis is how limits can be constructed to the exercise of EU powers. While there are limits to the exercise of EU competences in the Treaties and in the Court of Justice’s jurisprudence, it is argued that those limits suffer from conceptual and practical problems. In particular, the Court does not have appropriate criteria to examine whether the limits of the Treaties h
The decoupling of energy use from economic growth is an essential element in the transition to a sustainable future. However, little is known about the long-term drivers of decoupling, especially considering the possibility that it is at least partially due to increased trade. This study uses structural decomposition analysis to examine the main factors that contribute to changes in the energy foo
A 19-year-old female had recurrent bouts of pancreatitis. At endoscopy a mucosa-covered mass lesion was seen in the duodenum. A double-contrast examination of the stomach and duodenum showed an intraluminal duodenal diverticulum (IDD). Also an inversed abdominal situs and a midgut malrotation were noted. Computed tomography revealed evidence of a polysplenia syndrome. Although this syndrome is ass
The integrity of isolated mitochondria can be estimated functionally using enzymatic activities or the permeability of mitochondrial membranes to molecules of different sizes. Thus, the permeability of the outer membrane to the protein cytochrome c, the permeability of the inner membrane to protons, and the permeability of the inner membrane to NAD+, NADH and organic acids using soluble matrix deh
How corporations surveil and influence consumers using big data tools is a major area of research and public debate. However, few studies explore it in relation to physicians in the USA, even though they have been surveilled and targeted by the pharmaceutical industry since at least the 1950s. Indeed, in 2010, concerns about the pharmaceutical industry’s undue influence led to the passing of the P
A controlled, highly engineered landfill has many similarities to natural peatlands or other natural anoxic sediment deposits. In anaerobic MSW landfills, generally about 30-50 percent of the total carbon content in the waste can be converted into biogas and be collected as resource for energy or chemical industry. Remaining long-lived organic carbon, e.g. from lignin remains un-degraded, Organic
When engaging in international collaboration, researchers and research institutions have to relate to a great range of differences in legislation, scientific practices, incentive systems, and cultural norms. The research landscape has become even more complex in the last decade, and the gray zones at the intersections of a diverse set of institutional contexts may be used to push boundaries. The f
