Great salt lakes around the world are drying at a rapid rate. The drying salt lakes gives rise to several health and socio-economic concerns for the population in the surrounding region. The respective governments undertook various measures to address the concerns relating to the drying of salt lakes. This research aims to assess the strategies towards increasing the water level of saltwater lakes

Denna rapport identifierar och analyserar investeringsmöjligheter samt produktionsoperationella förändringar i produktionen av hålpipor. Studien avser en ledande svensk tillverkare i branschen och påbörjas med en analys av företaget självt samt dess kunder. Därefter undersöks förtegets nuvarande produktionsförmåga, varvid investeringsmöjligheter identifieras och analyseras. Slutligen diskuteras ocThis report identifies and investigates possible investment alternatives and operational improvements to the production of perforating punches. The analysis is conducted for a leading Swedish manufacturer in the industry. First, an analysis of the company and its customers is performed, followed by a study of the current production capabilities. Based on this investigation, key investments opportu
In 2023, the Swedish state-owned enterprise LKAB revealed that it had found Europe’s largest deposit of critical minerals, which are needed in green technology. Being located on indigenous territory, a mine would impact the migration of reindeers, a Sami practice which form the basis of their culture and status as indigenous peoples under international law. This prompted questions about what respo
Wound healing is a process that ensures regeneration and repair of damaged tissue. This process can be interrupted, leading to chronic wounds, and one of the factors that can interrupt it is infection. The bacterium Pseudomonas aeruginosa is prevalent in chronic wounds, and as it is antibiotic resistant it makes chronic wounds infected with this pathogen a challenging clinical problem. For a bette
The Circular economy (CE) is an economic system created as an alternative to the unsustainable linear economy. CE and its business models aims to deal with the challenges as resource depletion, waste creation and over consumption by closing the material loop. CE is today practiced using different business models. One such business model is remanufacturing. A business model that has gained a lot of
The telecommunication industry contributes to environmental impacts through energy usage and material resource use. The incorporation of Circular Economy strategies has the potential to restructure and re-engineer systems like those in the telecommunication industry to capture more value for the business while decreasing environmental impacts of business. The objective of the research in this pape
Presterar barn som blivit ammade bättre inom utbildning och arbetsmarknad som ungdomar och vuxna? Investeringar i insatser som främjar och stödjer amning kan leda till mer humankapital på lång sikt. Amning har många hälsorelaterade fördelar för både mamma och barn, trots detta byts bröstmjölk allt för ofta ut mot modersmjölksersättning. Denna studie jämför långsiktiga prestationer inom utbildning Does being breastfed as a baby lead to better achievements in education and on the labour market as an adolescent and adult? Investing money on interventions promoting and sustaining breastfeeding might lead to more human capital and be an economic gain in the long-run. Breastfeeding has many health-related benefits for both mother and child, nevertheless breast milk all too often gets substituted
For a long time, the construction and building industries have focused on increasing the efficiency of the built environment and reducing the emissions during the operations of buildings. As a consequence of the decreased operational emissions, the share of so-called embodied and upfront carbon has increased. In the life cycle of a building, the upfront carbon is associated with the emissions from
This MSc Thesis’s main objective is to determine the impact of transformer inrush currents in the grid and develop a tool that helps E.ON Energidistribution AB evaluate transformer sizing. The motivation of E.ON is to have a more precise way to estimate the energization consequences of increasing the transformer size in the grid, since currently is being used a rule of thumb that relates the trans
COVID-19 was declared a world-wide pandemic in 2020, consequently affecting societies all around the globe. This thesis investigates one of these effects, namely how the pandemic affected occupant loads in office buildings and its subsequent effect on fire evacuation. Occupant load is one of many important factors when designing a building in regard to its fire safety, as it is a key component in
The fermented tea beverage kombucha is a traditional drink that has been consumed for thousands of years in Asia. Over the past decades, it has gained greatly in popularity amongst consumers and researchers also in the rest of the world. Kombucha is produced through fermentation of sweetened tea by a complex community of bacteria, mainly dominated by acetic acid bacteria, and a variety of yeast. D
Fractal curves are self similar objects, most of which have the property of being nowhere differentiable. The foundations of fractal curves are in the study of continuous functions with no points of differentiability. In this thesis, the continuity and nowhere differentiability of the Weierstrass function will be proved by using an auxiliary function and mostly elementary tools from Fourier analys
Women’s labour force participation has historically been impeded by their traditional role of taking care of children, a problem that has been reduced with the emergence of formal daycare. However, one problem that remains is that many children in Sweden still do not participate in preschool. Among these children, there is an overrepresentation of foreign-born children and children from low-income
Lake sediments have lately been explored as a 10Be archive, complementing previous research on ice cores and marine sediments. 10Be is an important proxy as it can be used to study past solar activity, a factor which affects the climate. Where other methods studying solar activity only cover a brief period of history, 10Be has the potential to go further back in time. The concentrations of 10Be st
The European Spallation Source ERIC is a new neutron spallation source being built in Lund, Sweden, with NMX as one of the pioneer instruments. NMX is a Quasi-Laue single crystal neutron diffractometer for the investigation of large biological molecules. Wavelength, size and divergence of the neutron beam reaching the sample have to be controlled to properly match the different experimental needs.
The industrial food production system have given rise to tens of thousands of local, national and international social movements concerned with food and agriculture, reacting to the perceived social and environmental failures of the industrial food system. One of the directions inside these movements is the internationally based “local food” movement. The ”local food” movement promotes small-scal
