The specific insertion of a divalent metal ion into tetrapyrrole macrocycles is catalyzed by a group of enzymes called chelatases. Distortion of the tetrapyrrole has been proposed to be an important component of the mechanism of metallation. We present the structures of two different inhibitor complexes: (1) N-methylmesoporphyrin (N-MeMP) with the His183Ala variant of Bacillus subtilis ferrochelat

Detailed stratigraphic analyses of sediments deposited in Lake Botjarnen, a small boreal forest lake in the shield terrain of central Sweden, clearly reflect progressively increasing human impact on terrestrial and aquatic ecosystems following settlement and establishment of an iron industry in the 17th century. Rising frequencies of pollen and spores from light-demanding plants provide evidence o

This article discusses the advantages of the the Coherence Based Genealogical Method (CBGM), not only as a tool for reconstructing the text of the New Testament, but also for surveying the history of readings and for explaining textual changes. The CBGM promises to detect readings, which have emerged several times independently in the textual tradition. The method is applied to selected examples i

Background: The Locomotor Capabilities Index (LCI) is a validated measure of lower-limb amputees' ability to perform activities with prosthesis. We have developed the LCI Swedish version and evaluated its validity and reliability. Methods: Cross-cultural adaptation to Swedish included forward/backward translations and field testing. The Swedish LCI was then administered to 144 amputees (55 women),

Abstract in UndeterminedThe point of departure in my story is the contrast between two models of democratic voting process: popular democracy and what might be called committee democracy. On one interpretation, voting in popular democracy is a procedure whose function is to aggregate the individuals’ preferences to something like a collective preference, while in committee democracy what is being

The purpose of this thesis is to examine how increased mobility of indigenous student migrants in Dhaka from the Chittagong Hill Tracts in Bangladesh affects notions of belonging and indigeneity. By applying a theoretical framework of mobility, global interconnectedness and lifestyle, the study challenges representations by indigenous rights advocates of indigenous people as inherently immobile an

Popular Abstract in Swedish Syftet med denna studie var att (I) utvärdera sambandet mellan övervikt mätt med det s.k. body mass index (BMI) och operation med höftleds- eller knäledsprotes (konstgjord led) på grund av artros, (II) utvärdera sambandet mellan mekanisk belastning på grund av yrke och operation med höftleds- eller knäledsprotes på grund av artros, (III) utvärdera naturalförloppet för eThe purpose of this study was to (I) assess the association between body mass index (BMI) and total hip replacement (THR) and total knee replacement (TKR) due to osteoarthritis (OA), (II) assess the association between the mechanical load of work and THR and TKR due to OA, (III) evaluate the natural history of radiographic hip OA with regards to THR and hip fracture, (IV) to determine the prevalen

In light of heightened interest in the response of pollen phenology to temperature, we investigated recent changes to the onset of Betula (birch) pollen seasons in central and southern England, including a test of predicted advancement of the Betula pollen season for London. We calculated onset of birch pollen seasons using daily airborne pollen data obtained at London, Plymouth and Worcester, det

The migration politics in Sweden have changed drastically within the past years as it has introduced stricter asylum policies and higher securitisation of borders. As a result, an increased number of people are forced to live as undocumented migrants, meaning without a legal permit to stay in the country. This thesis aims to contribute to the analysis of this development by investigating the role

Att utveckla kollektivtrafiken är ett viktigt steg för att uppnå de klimatmål Sverige har åtagit sig att följa. Ett verktyg i utformningen och kapacitetsutvecklingen av hållplatserna är trafiksimulering. Detta arbete utforskar hur hållplatser kan på bästa sätt modelleras och kalibreras för fotgängare i programmet Vissim som är en simuleringsmjukvara utvecklad av företaget PTV Group. Vid kalibreriThe development of public transport is an important step toward reaching the climate goals Sweden has set. Traffic simulation is an instrument when developing and designing public transport stops. This thesis investigates how public transport stops can be modeled and calibrated for pedestrians in the PTV groups software Vissim. During the calibration, the platform was divided into four different z

Background: Adaption of Industry 4.0 is the new trend in developing countries mainly to obtain more efficiency and profitability. But to implement industry 4.0, developing countries are facing many challenges that need to be researched. Moreover, due to COVID- 19 pandemic and restrictions all around the world, have huge effects on the implementation of industry 4.0. Many companies are forced to im

Molasses is a low value by-product from sugar production that is usually used for animal feed, bioethanol fermentation, and yeast growth substrate. Even though it is a by-product and most of the sugar have been taken out the molasses still contains a fair amount of sugar that can be used for production of HMF, a biobased platform chemical with many areas of application, for example as a feedstock

Carbon dioxide removal (CDR) is quickly moving from mere imagination to material reality. As I write, billions of dollars are flowing into this nascent industry from government, philanthropy, and venture capital; this thesis thus attempts to grasp history as it flies. By employing a Marxist theoretical approach, including concepts like the real subsumption of nature and the spatiotemporal fix, I d

The aim of this thesis is to contribute to highlighting how economic environmental and climate ideas are expressed in the Secretariat of the World Trade Organization and to compare this with how they are expressed in other international organisations. In the article The evolution of ideas in global climate policy, Jonas Meckling and Bentley B. Allan map the evolution of economic environmental and

Denna studie utforskar hur betydelse av psykometriska tester inom rekrytering konstrueras och upprätthålls under processen av meningsskapande. Resultatet visar att rekryterare skapar mening av psykometriska tester utifrån en ram av objektivitet. För att upprätthålla den ramen använder de fem skyddande meningsskapande strategier i form av minimerande av begränsningar, användande av metaforer, analoThis study explores how meaning about psychometric testing within recruitment is constructed and sustained through the process of meaning making. The result shows that recruiters view psychometric tests through a frame of objectivity. To maintain that frame, they use five protective meaning making strategies such as downplaying limitations, using metaphors, analogies, narratives and dialogues.

The matters of economic growth and climate change are both widely subjected to discussions and policymakers are under immense pressure to make decisions that enhance economic growth and stop climate change. Policies that ensure economic growth have traditionally had a negative impact on climate change and vice versa. It is therefore important to study how various policies can address the connectio

Publications have recently drawn attention to archaeology’s historically predominant focus on prestige items and the elite, highlighting the need for a greater focus on society’s lower classes. A few studies have discussed how, or even whether poverty can be addressed in historical archaeology. However, the phenomenon has not seen the same attention in Viking Age studies, despite the great deal of
