Popular Abstract in Swedish För att levande celler ska kunna föröka sig behöver förr eller senare celldelning ske. Detta är en process där en ny cell skapas utifrån den information som finnas lagrad i ursprungscellen. Denna typ av information lagras i cellens DNA. En stor del av DNA:t är ritningar för hur cellens arbetarmolekyler, proteinerna, ska byggas men DNA:t innehåller även information för rIt has been more than 50 years since the enzyme system ribonucleotide reductase (RNR), catalysing the reduction of ribonucleotides to deoxyribonucleotides, was first discovered. RNR was also the first time that radical chemistry was revealed in an enzyme. RNRs carry out a key step in the de novo synthesis of building blocks for DNA and have been found in almost all known organisms. Within this th

Although microalgae have been considered for the biological treatment of wastewater since the 1950’s, their potential to efficiently remove pollutants from various streams remains largely untapped and is yet to be utilized at large scale. The production of algal biomass and extraction of high-value compounds has, however, become increasingly popular with large scale farms and biorefineries around Harnessing Microalgae: Transforming Wastewater into Valuable Pigments Innovative solutions are constantly sought to address the challenges of wastewater treatment and the increasing demand for sustainable products. One promising approach involves utilizing microalgae in a biorefinery system that not only cleans wastewater but also extracts valuable pigments from the biomass. This concept presents

Studien syftar till att öka kunskapen om riskerna som kan påverka tidsåtgången för underhållsarbete inom järnvägen, särskilt vid byte av fast korsningsparti i spårväxlar. Den tid som vanligtvis tillges vid underhåll ger inget utrymme för att oväntade händelser uppstår, därför är det av stor vikt att underhållet utförs effektivt för att slutföras inom tidsramen. Riskhanteringar utgörs av följande mThe study aims to increase knowledge about the risks that can affect the time required for maintenance work on railways, particularly when replacing fixed crossing sections in switches. The time allocated for maintenance usually does not allow for unexpected events, so it is crucial that maintenance is carried out efficiently to be completed within the timeframe. Risk management comprises the foll

Introduction: The popularity of para sports is steadily growing along with the biggest para sport arrangement, Paralympics. There is limited research in the field of physiotherapy when it comes to Paralympics and with the growing movement, more research is required. Shoulder injuries occur in all sports and are common in para sports. For disabled athletes, injuries may not only impact their sporti

Under de senaste åren har växthuseffekten växt och ökat i en otrolig fart som en effekt av allt koldioxidutsläpp som genereras av förbränning av fossila bränslen i dagens industri. Det har bidragit med att vi har fått klimatförändringar som ökade temperaturer på jordens yta runt om i världen. Ett stort fokus idag runt om i världen är att hitta ett sätt att dra ner på mängden utsläpp av koldioxid. Reducing CO2 emissions from combustion of fossil fuels is a big priority around the globe today. Some strategies to minimize air pollution and the increasing greenhouse gas effect are using recyclables and CO2 tax but an energy source replacement from fossil fuels is needed. Renewable energies are a good source of energy, but a stable storage system is required in order to be able to implement thi

Popular science Biogenic volatile organic compounds (BVOCs) are a versatile group of non-methane hydrocarbons (chemical compounds made of carbon and hydrogen) emitted by vegetation. The most common BVOCs from plants are some chemical compounds like isoprene, monoterpenes and sesquiterpenes. BVOCs are involved in plant growth, reproduction and defense mechanisms. Besides, BVOC play an important rol

Limited-slip differentials (LSD) are normally placed in high-end and race cars to improve the handling, by reducing the differential speed and balancing the torque between the driving wheels. However, electrical-activated LSD struggles to continuously eliminate the differential speed over extended periods of time. To overcome this, BorgWarner proposed a dual-functional clutch pack, featuring two d

Forest plantations play a crucial role in the livelihoods of Rwandan people. They provide valuable wood resources, such as timber and biomass energy. The first plantations created in the colonial period from 1920 to 1948 contained only exotic Eucalyptus species, which is thought to out-perform native species in terms of more rapid wood production. Over time, this resulted in the domination of non-

Condition Based Monitoring techniques have been developed to monitor the condition of critical components in machines. The most widely used technique to detect damage in machine components is vibration monitoring, but there are areas where other methods could be a better option. Vibration measuring can also be used as a broader search for damage in components while other methods can specify the ex

Considering the growing pressure on various ecosystems all around the world, the development of ecological indicators for assessing the health and condition of the ecosystems has become an integral part of environmental management and policy making efforts. Such indicators do not only simplify the complex ecosystem processes but can also act as a measure of performance of a conservation policy. Th

Title: Critical success factors that influence the corporate venturing process Seminar date: 2013-05-02 Course: ENTN39 Internship and Degree Project Authors: Martin Zündorf & Marcus Holgersson Advisor/s: Joakim Winborg Purpose: We investigated the influence of different factors on the corporate venturing process. Therefore we combined several factors from the organizational level with cha

Popular Abstract in Swedish Avhandlingens syfte är att ge ett bidrag till att belysa hur olika teorier och modeller kan förklara den sociala, kulturella och psykologiska situation som en avgränsad grupp kvinnor med narkotikaproblem befinner sig i. I avhandlingen görs en ansats att integrera ett socialpsykologiskt perspektiv med ett kvinnoforskningsperspektiv och ett personlighetspsykologiskt perspThe purpose of this study was to systematically examine the social, cultural and psychological situation of a group of women with drug addiction, and to gain an understanding of it. Different theoretical perspectives were utilized in efforts to understand and explain why some young women start using drugs. The attempt was made to integrate a social psychological perspective with a perspective base

Popular Abstract in English If you wonder about the journey of goods and services before they reach you and the effects that journey has on the natural environment and the society, this dissertation is for you. In order to deliver goods and services from raw materials to you, the customer/consumer, several organizations and individuals interact with each other. They source the materials, manufactuTo develop sustainable supply chains in a way that their negative environmental and social effects are minimized, shortand long-term targets should be set. The transformation of supply chains towards these targets calls for the development of innovative strategies and the need to continuously identify, classify, and tackle the challenges that can hinder the execution of such strategies. To develop

Cementproduktion står idag för en ansenlig andel av världens koldioxidutsläpp, vilket driver utvecklingen av bindemedel med lägre koldioxidutsläpp. För utsläppen i ett längre perspektiv är dock de nya bindemedlens beständighet absolut avgörande. De flesta nedbrytningsmekanismer är direkt relaterade till både fukt- och jontransport. Dessa processer har undersökts i många studier, men huvudsakligen Cement production is responsible for a significant portion of manmade CO2 emissions. This motivates the development of cementitious binders with a lower carbon footprint. Considering the emissions in a longer perspective, the durability of concrete structures is absolutely essential. Most degradation of concrete structures is closely related to both moisture transport and ion transport. Many studi

When making decisions regarding investments and planning of the distribution network, it is of great help to be able to calculate and analyze the reliability. The main interest is to study how many of the faults occur and the duration of these faults. The software Tekla NIS contains a module for calculation of the reliability of distribution systems, this is also known as reliability based network
