Research on dark matter has been ongoing for almost a century. Findings show that dark matter makes up 27% of the universe’s density and thus it is a crucial component of understanding how the universe came about. This thesis describes the key pieces of evidence for the existence of dark matter and its properties. An emphasis is put on the effects of dark matter on processes in the early universe.

This thesis describes the process and the approach taken to determine the current limitations and potential improvements of the GPX Porosity prototype. To continue the development of the GPX Porosity instrument, a series of comparative measurements has been performed on pharmaceutical ribbons, to understand better what are the factors limiting the optical porosity measurement precision and if oth

Background: Previous study found that 2 batches of Nopal flour supplied by the same suppliers at different time was performing different results in in vitro studies and the quality of Nopal flour might thus be different. Besides, investigation on whether the soluble or the insoluble fraction of the Nopal flour suspensions contributed to the glycemic modulation was still necessary. Method: Compo

This master thesis explores commercialization of electric road systems in urban environments, using a combined methods approach, in contrast to previous studies that have focused on long haul transportation. First, through interviews and document gathering, a stakeholder map was constructed, and the incentives of the identified stakeholders were analyzed. The thesis found disagreements between the

Uppsatsen har en grund i problematiken kring det faktum att många arbetsgivare kringgår lagen om

The 83 million year old family tree of burnet moths To classify the living world around them, early on humans started naming plants and animals in order to distinguish food from non-food, predator from prey, etc. In 1800s a practice of a more formal way of classifying the living world was started, in which using Latin names made the classification universal. The unique appearances were used to di

Conductance was calculated for trapezoidal nanowires with different forms and strengths of imperfection using kwant, a quantum transport software package that uses a tight-binding model. In this thesis it is found that increasing magnitudes of different imperfections such as surface charge and roughness roughen conductance steps, introduce resonances, and lower conductance overall with different c

Introduction: This study was performed to optimize extraction of lead, copper and zinc from seaweed using pressurized hot water, to investigate the selectivity and extractability of the extraction. Background: Pressurized hot water extraction is an environmentally sustainable method in comparison to more common extraction methods, such as distillation or solvent extraction, used with plant mater

På Lunds Tekniska Högskola studenter som studerar på programmet Civilingenjör inom Kemiteknik en obligatorisk kurs Energiteknik KETF30. Kursen har ett laborationsmoment om värmeväxling som behöver förnyas. Målet med kandidatarbetet är att få fram en laborationsbeskrivning med fokus på värmeväxlarens beteende beroende på olika parametrar och jämföra de två metoder som kan användas för att beskriva At Lund University, students in the program Chemical engineering have a compulsory course Heat Engineering (Energiteknik KETF30). The course has a laboratory practical concerning heat exchanger that needs to be renewed. The goal of this bachelor thesis was to write a description for the practical, focusing on the heat exchanger’s behavior considering different parameters and comparing the who comm

The main purpose of this study is to research how an organization can develop, implement and measure the effect of employee well-being strategies to ultimately boost the organization’s bottom line. In this exploratory case study, SAP served as the case of investigation and primary data was collected through six qualitative interviews. The sample included SAP representatives from different levels o

Utmaningar och möjligheter kring laddinfrastruktur i en mindre kommun i södra Sverige. Var ska laddstolparna sitta och vilka betalningsmodeller kan fungera här? När det kommer till implementering av laddinfrastruktur är det viktigt att den är kommunanpassad. De val av platser som görs samt vilka betalningsmodeller som väljs är helt beroende av kommunens förutsättningar. Uppsatsen är ett arbeteThe development surrounding electric vehicles has made a leap forward in the last two decades. More and more people buy electric vehicles, especially cars, both around the world and in Sweden. To accommodate the rise in electric cars, governments and municipalities need to invest in charging infrastructure. This study was conducted in collaboration with Klippans municipality in southern Sweden. Th

Title: How to become one in reality – A qualitative study about how different factors can influence knowledge sharing within cross-cultural virtual teams and how they can be facilitated Seminar date: June 3th, 2021 Course: BUSN39 – Degree Project in Global Marketing Researchers: Rebecca Roos & Mikaela Vanselius Supervisor: Ulf Elg Keywords: virtual teams, cross-cultural teams, knowledge

The aim of this study was to investigate the role of the counselor within the Swedish opioid maintenance program (LARO), considerations and experiences of patient processes as well as the treatment program. This in relation to the patient's possibility to initiate an exit process. The study was based on seven qualitative interviews with counselors within LARO. Furthermore, the study was based

Radar systems have been around since the early 20th century, and technology is advancing at an ever-increasing speed. This has led to great achievements in radar development, which have expanded the technology's area of use. One of these is the application of a security radar used in conjunction with security cameras for increased flexibility and reliability in security systems. A type of rada

Neural oscillatory activity represented in the time-frequency (TF) domain is believed to reflect cognitive mechanisms underlying episodic memory encoding and retrieval. Research has shown that encoding and retrieval processes are likely modulated by emotional valence. This study investigates how successful associative memory encoding and retrieval of content varying in valence (positive, negative,

E-commerce activities have been growing rapidly throughout the past decade, leading to a growth just as dominant in last mile logistics and urban freight transport as well. Different factors create these deliveries highly inefficient, expensive, and polluting. This led to the generation of major problems that became more dominant in urban areas. Such problems created in cities contributed to highe

The refugee crisis that occurred in 2015 proved to be a historical failure for the Dublin Regulation, and it demonstrated both to policymakers and public opinion that the account of solidarity upheld was strongly outdated. If the European Union truly is a community based on shared values, then axiological changes should also result in institutional changes. Acknowledging that no radical transforma

I Sverige är ägarförbehåll vanligt förekommande i handeln med kapitalvaror eftersom det är ett enkelt och billigt sätt för säljaren att få säkerhet för sin köpeskilling vid kreditköp. Den här uppsatsen syftar till att undersöka möjlighet-erna för en ägare av en näringsverksamhet att med sakrättslig giltighet förbehålla sig äganderätten till verksamheten vid försäljning av densamma. En överlåtelsIn the market of capital goods, a retention of title clause is a common and easy way for a creditor to get security for the payment. The purpose of this thesis is to investigate the possibilities for a seller of a business to use a retention of title clause, and get indefeasible protection, when he or she sells the business. A transfer of a business is often associated with long preparations and
