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

One of the most important trends in contemporary tourism is the increase in urban tourism, both in absolute and in relative terms. An increasing number of cities have become significant tourism destinations. Cities also attract an increasingly diverse set of visitors, some of which could be called alternative tourists.

1. IntroductionThe demand for efficient oil-water separation is driven by the tightening of discharge limits for e.g. produced water in the oil and gas industry, process water in the petrochemical industry and bilge water in the marine industry. The global produced water production alone is over 71 billion bbl/a – 8.4 billion m3/a [1]. Among the different technologies, particularly ultrafiltration

Recent years have proven the benefits of electrifying the road bound vehicle fleet. With new components entering, the general understanding as well as the components as such needs to be improved. Focus in the thesis is on the design of an electric machine based on specifications of requirements for a commercial heavy vehicle such as a truck or a bus. One strict requirement is that the machine has Recent years have proven the benefits of electrifying the road bound vehicle fleet.

This paper suggests an infrastructure perspective, as suggested by Star and Bowker (2006), as an analytical framework for studying the research evaluation landscape. An infrastructure is suggested to be understood, not as a concrete technology, but as a system of contextual factors including ‘Actors/Stakeholders’, ‘Technical systems’, and ‘Evaluation practices’. How the framework can be operationa

Purpose: Female survivors of childhood, adolescent, and young adult (CAYA) cancer who were treated with alkylating agents and/or radiation, with potential exposure of the ovaries, have an increased risk of premature ovarian insufficiency (POI). Clinical practice guidelines can facilitate these survivors' access to optimal treatment of late effects that may improve health and quality of survival; h

This white paper contains six policy ideas that may help countries in coping with theCOVID-19 pandemic. The paper focuses on policies that can slow down the spread of the disease, better protect high-risk groups and leverage that a large part of the labor force is idle. For each policy idea, we describe the problem it is meant to solve, what may be leveraged to solve it, and a brief analysis of be

On Friday June 10 2016, the Center for Middle Eastern Studies (CMES) at Lund University arranged a seminar devoted to explore refugee experiences among Syrians in the Öresund region. Organizers were CMES researchers Dalia Abdelhady and Joshka Wessels. Lund University and international researchers in law, religious studies, refugee studies, environmental studies, urban sociology and anthropology pa

This study presents the first results from an ongoing initiative to develop a multi-millennial Baltic tree- ring width (TRW) chronology consisting of 12 floating records from subfossil Scots pines (Pinus sylvestris L.) extracted from three Lithuanian peat-mining areas. The floating series have been complemented with absolutely dated TRW chronologies which were obtained from living trees growing inThis study presents the first results from an ongoing initiative to develop a multi-millennial Baltic tree-ring width (TRW) chronology consisting of 12 floating records from subfossil Scots pines (Pinus sylvestris L.) extracted from three Lithuanian peat-mining areas.

The emancipatory appropriation of space, in the sense making personal adjustments and manoeuvres in order to raise a sense of space, can be understood in terms of giving and taking form, or what Catherine Malabou calls “plasticity”. Spatial production is in this sense defined relationally and cannot be fully provided by programmed architectural functions.

We live in a time of wireless technologies, robotics and small computers with very high computing power. This is mainly due to a large emphasis given towards the study of semiconductor materials which are the building blocks of today's electronic industry. One of the secrets behind creating faster computers is the ability to integrate more and more transistors on a small semiconductor chip. GordonThis thesis studies the role of interaction between charged particles for transport and optical properties in nanostructures. Simulations are provided for a quantitative description of the system dynamics probed by either current spectroscopy or light absorption. In the first part of the thesis (Part I) the basic theories are described and in the second part of the thesis (Part II) the papers lis

This report presents the work developing a modular sailboat interior system that offers an easy and affordable way for recreational sailors to customize the interiors of their sailboats according to their different and changing needs. Cruising sailboats are like floating houses or cottages, with the difference that the interior is permanent. They have a long product life and often last for decade

Purpose: To investigate if it is possible to earn abnormal returns from the accruals based trading strategy in Sweden. The aim is also to examine if the benchmark used when classifying firms into accruals portfolios has an impact on the abnormal returns from the trading strategy. Methodology: The study investigates the abnormal returns from the trading strategy that aims to exploit the accruals a

Syftet med denna uppsats är att undersöka hur avvägningen mellan effektivitet och rättssäkerhet i förarbetena till skattetillägget kommit att påverka hur dagens skattetillägg fungerar i praktiken vid Skatteverkets kontrollverksamhet avseende tjänsteavdrag. Detta redogörs för genom att dagens regelverk och de förarbeten som legat till grund för skattetillägget analyseras i förhållande till effektivThe purpose of this essay is to investigate how the trade-off between efficiency and rule of law during the legislation processes for the tax surcharge has come to affect how today's tax surcharge works in practice regarding the Swedish Tax Agency's monitoring of tax deductions for work-related expenses made by natural persons. This essay will examine this through analyzing today's reg
