I denna rapport analyseras hur dimensioneringen av Rectiverter och UPS systemens storlek är anpassade för driftsplatsernas faktiska elförbrukning och vilka potentiella lösningar som finns för att effektivisera användandet av systemen för att minska elförbrukningen. Effektiviserandet av driftplatsernas system kommer att leda till en kostnadseffektivare anläggning. För svenska lågspänningsanläggningThis report analyzes how the size of Rectiverter and UPS systems is tailored to the actual electricity consumption at operational sites and explores potential solutions to optimize the usage of these systems in order to reduce electricity consumption. Optimizing the operational sites' systems will result in a more cost-effective facility. In Swedish low-voltage installations, a standard has be

Environmental Building Certification (EBC) assessments are often time-consuming and challenging, as they encompass a lengthy process that includes modelling, simulation, proofing, credit calculation, and report writing. Hence, there is a growing need to streamline this process. The objective of this thesis is to examine existing Building Energy Modelling (BEM) workflows and evaluate their abilit

The COVID-19 pandemic caused severe economic and social disruptions in Kenya, which exacerbated vulnerabilities and raised concerns about potential increases in human trafficking. Therefore, this qualitative case study examines how the pandemic affected human trafficking and NGO responses during this period. The primary data was collected through 14 semi-structured interviews with anti-trafficking

Objectives: Artisanal and Small-Scale Mining (ASM) - a labour-intensive and low-tech mode of minerals extraction and processing - has received increasing attention amidst global commodity booms and its concurrent expansion. Infamously associated with negative social and environmental impacts, responsible mining initiatives have emerged to promote, measure, and enforce sustainable mining practices

Context: Today, 96% of Sweden’s materials come from virgin resources and only 3.4% of resources used in Sweden are retained in the value chain. From a total of 266 million tonnes fed into the economy each year, 46.9% consist of construction materials. Hence, there is a need to adapt circular strategies, such as reuse of construction products, to meet Sweden’s goal of becoming net zero by the year

Stamceller är celler som kan omvandlas till vilken celltyp som helst, vilket gör dem mycket användbara inom olika medicinska behandlingar och undersökningar. Stamceller kan exempelvis behandla cancer och diabetes, men skulle även kunna användas till att bota förlamning. Idag pågår det mycket forskning kring hur vanliga celler kan omvandlas till stamceller. Genom att manipulera mängden olika transkSince stem cells have many applications in medicine and can be used for treating e.g. cancer and diabetes, finding efficient methods for producing them is a relevant area of research. Cell reprogramming is such a method and our collaborators recently showed that adding Hic2 to the existing protocols of methods increases the efficiency from 1% to 10%. In this thesis, I aim to investigate how an add

De flesta är medvetna om kolhydraters betydelse som näringsämnen och energikälla, men vad många förmodligen inte känner till är att kolhydrater är viktiga byggstenar i kroppen då de binder till olika proteiner och lipider och bildar så kallade glykoproteiner och glykolipider som finns bland annat i våra cellmembran. En viktig klass av kolhydrater är glykosider som består av en sockerdel som kallasThe one-step conversion of unprotected sugars to sugar intermediates invented by the Shin-ichiro Shoda group at Tohoku University in Japan by using 2-chloro-1,3-dimethyl-imidazolinium chloride (DMC) as a dehydrative condensing agent is a relatively new way to synthesize carbohydrate derivatives. A great effort has been done to investigate the minimum requirement of bases, the suitable dehydrative

The purpose of this study was to examine disinformation regarding Swedish Child Protective Services in the online forum Flashback through a constructivist perspective with a focus on conspiracy theories regarding the subject. The study is an internet-based study with a netnographic approach. The focus was to analyze the unfounded claims that the Swedish social services wrongfully apprehend childre

The aim of this study was to investigate the functional properties and stability of hybrid pea-dairy protein formulas. To achieve this goal, the combination of pea protein isolate (PPI) with dairy proteins such as micellar casein isolate (MCI), sodium caseinate (NaCas), whey protein aggregate (WPA) was evaluated. Samples stored for 2 and 4 weeks at 4oC and 20oC were visually assessed and physicoch

Kan hemoglobin från växter lösa humana problem? Dagligen tar vi för givet att vårt blod syresätts tillräckligt för att orka med alla sysslor. Detta möjliggörs av det livsviktiga proteinet hemoglobin som finns i vårt blod. I dagens samhälle råder det dock blodbrist samtidigt som många drabbas av järnbrist. Det är där forskningen på växthemoglobin kommer in i bilden. Experimenten som genomförts i dThe protein hemoglobin (Hb) is vital for us humans to ensure enough oxygen replacement in the body. Hb-resembling proteins also exist in plants, these are called phytoglobins (Pgbs). Pgbs are very interesting since they can play a considerable role in the development of blood substitutes and iron supplements for human use. A few years ago, genes that code for Pgb in sugar beet were found and ident

Små partiklar från nedbrytning av plasten polyeten kan leda till ytterligare miljöutmaningar Plast produceras idag i stor omfattning och en stor del av plasten som används hamnar i naturen. När plasten bryts ned till mindre partiklar av bland annat mekaniska påfrestningar och UV ljus, kan dessa ta sig in i vävnader hos djur och människor och orsaka skada. I vilken utsträckning dessa partiklar påvePlastic pollution is an urgent environmental problem. Plastic can break down in nature into micro- and nanoplastics, and the impacts of these, and especially nanoplastics on the environment are not fully understood. Particles have been shown to accumulate in tissues of animals, where they are believed to cause cell damage. In this project, LDPE was broken down, filtered to obtain nanoplastics, sep

For the fourth year in a row, Poland continues to rank as the lowest country of the European Union on the yearly report on the legal and political situation of queer people in Europe. With constant negative media portrayal of queer communities and homophobic remarks from politicians, Polish queer individuals become antagonized and stigmatized by the society. This thesis aims to explore the less re

Dry etching is one of the most important methods of pattern transfer in nanofabrication. There are many dry etching methods, the most commonly used is reactive ion etching (RIE), that is based on a continuous supply of reactive ions and radicals generated in a radio-frequency (RF) plasma discharge. The RIE approach can be very accurate and may provide high resolution etching, below 10 nm in latera

It is known that the phenomenon of child language brokering, where children act as interpreters for family members, exists in Sweden. Several studies have shown problematic aspects of the practice. The aim of this study was to explore young adults' experiences of child language brokering in appointments with professionals. The method chosen for this study was qualitative interviews with nine y

Over time, these

HR-yrket är i ständig förändring och upplever i dagsläget ett stort intresse från organisationer runt om i landet för deras många kompetensområden. Med detta i åtanke är det av vikt att HR-funktionen bemöts på rätt sätt och har de verktyg som behövs för att kunna prestera. Denna studie ämnar därför att besvara två frågor: vilka krav och förväntningar existerar på HR-praktiker från olika sidor av o

This paper discusses implementation techniques for integration methods within the Discontinuous Galerkin Methods. These methods are used to approximate solutions for differential equations. To do so, one must compute a polynomial, which is an approximation of the used function. To compute this approximation, orthogonal polynomials, chosen to be the Legendre polynomials are used, as well as integra
