USING CRISPR/Cas9 TO DELETE REDUCTASES IN YEAST TOWARDS IMPROVED CAPSAICINOID BIOSYNTHESIS
The baker’s yeast, Saccharomyces cerevisiae (S. cerevisiae) was studied and genetically engineered. This was to enhance the transamination step of the biochemical reaction cascade towards the production of capsaicin. Inherent reductases were identified and twelve of them knocked out via homologous recombination. Using the CRISPR/Cas9 technology, the Green Fluorescence Protein (GFP) gene was introd
Utvärdering av anlagda våtmarker i Örupsåns avrinningsområde - Ett arbete om anlagda våtmarkers effekt på vattenkvaliteten i Örupsån, Tomelilla kommun
Jordbruksmarken i Sverige är en stor anledning till varför en stor mängd kväve och fosfor transporteras till vattendrag, sjöar och hav. Näringstransporten medför konsekvenser för miljön då växtorganismers förutsättningar förändras och övergödning sker. Våtmarker är ett naturligt inslag i miljön som har näringsrenande egenskaper gällande kväve och fosfor. Under det senaste seklet har uppemot en fjäThe agricultural land in Sweden is a major reason why a large amount of nitrogen and phosphorus is transported to rivers, lakes and the sea. Nutrient transport has consequences for the environment as the conditions for plant organisms change and eutrophication takes place. Wetlands are a natural part of the environment that have nutrient removing properties regarding nitrogen and phosphorus. Durin

Chromosomal DNA Barcode Assembly Using Hierarchical Clustering Matrix Method: Including Elastic Matching
Obtaining DNA sequences is a time-consuming task, which typically requires one or several days for completion. One way of reducing analysis times is to be satisfied with long-range sequence patterns on the order of thousands of base pairs. DNA barcoding is a DNA-characterising technique that works according to this principle. It does so by using fluorescence microscopy to visualise long-range sequ
Self-adaptive random walk with pesudo-gradients for genetic evolution of an artificial neural network
To optimize the weights in an artificial neural network most methods rely gradients, which are not always obtainable or desirable. Evolutionary algorithms are instead based on Darwinian evolution where no derivative is needed. These algorithms have a set of strategy parameters that can be dynamically updated during the search to increase performance. Two ways of updating the parameters are the so
Revisorns relation till klienten - konsekvenser för revisionskvaliteten
Purpose: The purpose of this essay is to examine the different relationships between the auditor and its clients and how this relationships affects the quality of the audit. Theoretical perspectives: The theoretical framework is based on a description of relationships based on Duff (2014) and a description of audit quality which is partly based on Tepalagul & Lin (2015) and Wright & Wrigh
Effects of reindeer grazing on the fungal community in subarctic mountain birch woodland and open tundra: implications for soil carbon storage
Due to a warming climate, tundra ecosystems are subject to shrub and treeline expansions which could lead to increased above- but decreased belowground carbon (C) stocks. An observed low soil C stock in some subarctic forests and tall shrublands has been suggested to be induced by priming of organic matter decomposition, possibly mediated by ectomycorrhizal fungi. On the other hand, the higher bel
MEDELTIDA TEGELPRODUKTION I LUND
I en jämförelse mellan det skriftliga och det arkeologiska materialet framträder en bild av medeltida tegelbruk i allmänhet och det medeltida tegelbruket vid S:t Mikael i synnerhet. Arkeologiskt iakttagbara anläggningar vid ett medeltida tegelbruk, förutom en tegelugn är följande; lertag i form av gropar eller stora gravar (eventuellt vattenfyllda), vallar efter leran som lagts till vintring, gropWhen, why and how the brick-making tradition started in the Nordic countries is well known. However, research on the spatiality and layout of the the production of bricks in medieval times is lacking. What archaeologically observable sites, apart from a kiln, were part of a medieval brickyard and how were they organized? In a comparison between written material on brick production and archaeologic
Licensing in Pharma - Value Creation and Appropriation
We unify literature on licensing in the pharmaceutical industry and empirically verify pre-established and identify new determinants of value creation and appropriation based on a contemporary data set of licensing deals made between 2015 and 2020. We observe positive returns for licensor and licensee. A return differential indicates value appropriation by the licensor due to scarcity. A positive
MECHANISMS OF STREPTOCOCCUS PNEUMONIAE BIOFILM FORMATION; THE ROLE OF PSRP AND DIFFERENT CARBON SOURCES
Respiratory tract infections (RTIs) are a major global health concern. Several studies indicate that most respiratory bacterial pathogens are capable of asymptomatic colonization and find their primary ecological niche within the nasopharynx of healthy individuals as harmless commensals that form biofilms. However, in response to external factors, such as concomitant virus infections, colonizing b
An analysis of inter-annual and withinwinter survival among rural and urban great tits (Parus major)
Birds endure ecological constraints during winter in temperate regions where critical resources vary significantly between urban and rural sites, influencing survival rate. Warmer temperatures and artificial food sources have led to an increase in urban avian winter abundance whereas birds in colder, rural ecosystems are more reliant on scarce natural food sources but subject to less human disturb
Migration strategy and winter area use of common swift (Apus apus) breeding in the Netherlands – using combined GeoLight and FlightR approach
Migration is an adaptation for birds to exploit the resources that change temporally and spatially. The recent development of miniature light level geolocators has revealed this previously poorly known aspect of birds. From light intensity data together with time recorded by geolocators, we can infer the positions of the birds, i.e. latitudes and longitudes, using a threshold method or a curve-fit
"Statstjänstemän har inte så mycket känslor" : En kvalitativ studie i hur beslutsfattande personal vid Migrationsverkets asylenhet utför emotionellt lönearbete
Studiens syfte var att uppnå en ökad förståelse för hur beslutsfattande personal med erfarenhet från Migrationsverkets asylenhet, upplever att de förhåller sig till, påverkas av- samt hanterar arbetsrelaterade emotioner i förhållande till asylenhetens emotionsregim. Syftet var därmed att genom kvalitativa intervjuer undersöka hur personal förhåller sig till en sådan emotionsregim vilken reglerar a
Age-related differences in songbird migration performance in autumn
Migration to wintering grounds is a process that a large proportion of songbirds perform every year. It has been suggested that there are differences in the migration performance between adults and juveniles due to the experience the former have over the latter, after having flown this journey before. The aim of this study was to analyse age differences regarding activity, energy deposits and depa

Dengue is just regular flu but also kills many people all around the world. We all happen to know that dengue viruses have been on the march for the last 100 years. During the late 20th century, it became a serious threat to mankind. Our scientists have been putting their utmost efforts to save people from dengue infections. They have come up with a number of vaccinations and mosquito repellent so
Learning to unlearn - How individuals can BRACE themselves for the impact of organizational change
This study aims to gain a deeper understanding of how individuals, in an organizational context, experience the process of unlearning in relation to routines and how these individuals might be influenced in their unlearning process.
Finite Element Model of Mechanical Imaging of the Breast for OpenVCT Software Platform
Styvhetsförändringar i bröstvävnad är ofta kopplade till en patologisk förändring. Vissa cancertyper som infiltererande duktalt carcinom kan vara åtta gånger så styv som fettvävnaden runt omkring. Genom att komprimera bröstet och mäta trycket på bröstets yta har man identifierat att det blir en lokal förhöjning i tryck där det finns en tumör. Med hjälp av den här typen av mekanisk avbildning av brA change in stiffness of breast tissue is often connected to a pathological change. Some types of breast cancer such as infiltrating ductal carcinoma can be up to eight times stiffer than fat tissue. It has been found that during compression of the breast there will be a local area of relatively high stress at the breast surface at the location of a tumour. This type of mechanical imaging of the b
Physically Inspired Optimization
Optimization is the study of finding the best solution for a problem. The applications of this field ranges from finding the best routes for travelling to finding the ground state of physical systems. This thesis looks at gradient based and gradient-less optimization algorithms which are applied to two problems: the linear least square and the position of a system of springs. The algorithms used a
A Missed Steak: A Study of the Value Added by Dynamic Best-before Labels
I mogna industrier prioriteras ofta verkningsgrad och processen snarare än själva produkten. Detta innebär att dessa industrier anpassar sig långsamt när de externa förhållandena skiftar. Exempel på sådan industri är Sveriges köttindustri. Denna präglas av stor klimatpåverkan, även stora mängder matsvinn. Nya teknologier undersökes i nuläget för att skärpa detta svinn; exempel på sådan teknologi äThe competitive landscape mature industries find themselves in tends to make them enforce practices that ruthlessly focus on efficiency and process. This narrow focus makes them slow to adapt to changes in the external environment in which they operate. One such case is the Swedish meat industry. Like many industries, there are downsides involved with meat production and for meat a significant one
