Metalloenzymes are proteins that contain one or more metal ions bound to protein. They constitute about one-third of all enzymes known so far and they often perform hard chemical reactions involving small substrates, like H2 and N2. In our research, we focus on those metal ions that are located in the active sites and perform redox reactions, i.e. involving electron transfer. Why enzymes?Metalloenzymes catalyse a wide variety of reactions in nature. In the thesis, I have studied the reaction mechanism of three metalloenzymes, viz. [NiFe] hydrogenase (H2ase), dimethyl sulfoxide reductase (DMSOR) and formate dehydrogenase (FDH), by theoretical methods, namely quantum mechanics (QM), combined quantum mechanical and molecular mechanics (QM/MM), as well as QM/MM thermodynamic cycle per

Relationship marketing is getting more focus from researchers today. The idea of earning the trust and loyalty of customers by engaging in relationships has been put to practice in many retail areas. Retailers and researchers are stressing the importance of establishing relationships with their customers and are in many ways focused on the physical service encounter. Literature often suggests that

Varumärkesförfalskning är idag ett allmänt förekommande problem. Utbredningen av förfalskade varor riskerar att minska incitamenten att investera och bygga upp varumärken, på samma sätt som incitamenten att investera i och utveckla läkemedel skulle minska om möjligheten till patent försvagades. Varumärkesförfalskning är ett problem för både konsumenter och näringsidkare. Konsumenterna riskerar attCounterfeiting in gods is a fast growing issue affecting both consumers and businesses worldwide. Consumers might mistake a fake with the original product and traders threaten to weaken their brands and the sale is lost in favour of the counterfeit gods. In the long run the expansion of counterfeiting gods might lead to less incentives for businesses to invest and develop trademarks. From the firs

The new term “sustainability marketing communications” emerged and the has gained increased interests and implementations in recent years. The aim of the degree project is to provide suggestions to Skånemejerier on the basis of current state in dairies and trends in marketing communications in the entire industry. Benchmarking is applied throughout the study and two different benchmarking processe

Drawing on a playful notebook entry from Hans Jonas’s student years, this article examines why Jonas consistently sidestepped Friedrich Schelling’s Naturphilosophie in his writings on philosophical biology. It begins by outlining the many affinities between the two thinkers, as noted in previous scholarship: both articulate an asubjective teleology, both understand or­ganisms as self-individuating

Online retail is growing rapidly, but fierce and global competition poses a challenge for retailers seeking to compete on values beyond price. Research in product and physical retail branding shows that building a relevant brand image can increase consumers’ willingness to pay a premium over competing brands with similar products. However, the academic literature lacks understanding of how brandin

Visual cues provide an important means for aerial creatures to ascertain their self-motion through the environment. In many insects, including flies, moths, and bees, wide-field motion-sensitive neurons in the third optic ganglion are thought to underlie such motion encoding; however, these neurons can only respond robustly over limited speed ranges. The task is more complicated for some species o

BackgroundStreptococcus pyogenes bacteremia is a severe condition with high mortality. Time to blood culture positivity (TTP) is known to predict the outcome in bacteremia with other pathogens. This study aimed to determine the association between TTP and outcome in S pyogenes bacteremia.MethodsThis retrospective observational cohort study comprised adults with S pyogenes bacteremia, identified th

The domestic care work sector in Sweden is growing. The expansion of the welfare state in the post-war period made privately employed domestic workers an uncommon practice (Öberg, 1999). Today, we see a re-emergence of the market. The turning point for this is the RUT tax deduction, introduced in 2007 and leading to a tremendous growth in the sector. Approximately 30 000 people are employed in RUT

Phosphorus-driven eutrophication of surface waters persists across Europe and Water Framework Directive (WFD) implementation is slow. Calls for better management approaches advocate for involving multiple stakeholders, considering social, ecological and technological drivers, and applying ‘multi-level’ or ‘multi-scalar’ approaches. However, multi-level approaches rarely apply ‘scales’ and ‘levels’

The lack of secure property rights has been identified by a number of economists – past and present – as an obstacle for long-term growth of output of African farming. The foundation for such a claim is that insecure property rights hinder long-term capital investments. Although the observed infrequency of private property rights in African history is correct there are exceptions. This paper exami

Since the 1970s critical marketing scholars have called for systemic change to overcome the ethical problems generated by consumption, such as unsustainable resource use, industry-induced climate change, and social inequities. Mainstream marketing research has instead problematised the individual consumer and sought ways to diminish the so-called gap between ethics and consumption. The current con

Background: The molecular pathways linking short and long sleep duration with incident diabetes mellitus (iDM) and incident coronary heart disease (iCHD) are not known. We aimed to identify circulating protein patterns associated with sleep duration and test their impact on incident cardiometabolic disease. Methods: We assessed sleep duration and measured 78 plasma proteins among 3336 participants

Reconstructions of past land use and related land-cover changes at local and regional scales are needed to evaluate the potential long-term impacts of land use on the coastal waters of the Baltic Sea. In this purpose, we selected the Gamleby area at the Swedish Baltic Sea coast for a case study. We use a new, high resolution pollen record from a small lake (Lillsjön) located 3.6 km NNW of the bay

Situated in the intersection of the literature on QoL and lifestyle migration, this paper contributes to the discussion of three subjective components of QoL after migrating to another country. These are hedonic (happiness), evaluative (life satisfaction) and eudaimonic (having a purposeful or worthwhile life). Based on 36 in-depth interviews to Swedish citizens permanently living in Portugal, a g

Det är vedertaget i svensk rätt att avtal om framtida överlåtelse av fast egen- dom, såsom optionsavtal, är ogiltiga. En option är en rätt, men inte skyldighet, att i framtiden köpa eller sälja viss egendom. Även om det inte framgår explicit i lagtext eller förarbeten föreligger alltså i praktiken ett förbud mot option till fast egendom. Uppsatsens syfte är att granska huruvida det föreligger skäl

This essay explores the critiques of modernity from posthuman and Indigenous perspectives, exploring their convergences and divergences. It argues that both frameworks challenge the anthropocentric and dualistic paradigms that have historically governed Western thought. Posthumanism encourages ontological humility by recognizing the non-dual nature of existence and more-than-human agency, while In

Effects of carbon functionalization on the catalytic properties of the space underneath epitaxial graphene flakes on Ir(111) are investigated with Ambient Pressure X-ray Photoelectron Spectroscopy studies of oxygen hydrogenation. The 0.1 mbar oxygen atmosphere hosting O-intercalated graphene flakes was replaced with hydrogen pulses lasting 50 s each, triggering the water formation. Underneath pris
