Semiconductor nanowire (NW) solar cells with a single p-n junction have exhibited efficiency comparable to that of their planar counterparts with a substantial reduction in material consumption. Tandem geometry is a path toward the fabrication of devices with even higher efficiencies, for which a key step is the fabrication of tunnel (Esaki) diodes within NWs with the correct diameter, pitch, and

The detection of reactive oxygen species (ROS) after traumatic brain injury (TBI) is based on indirect methods due to the high reactivity and short half-life of ROS in biological tissue. The commonly used salicylate trapping method has several disadvantages making it unsuitable for human use. We have evaluated 4-hydroxybenzoic acid (4-HBA) together with microdialysis (MD) in the rat as an alternat

This case study aims to examine two questions. Firstly, how the theoretical perspectives of liberalism and realism can explain the approaches of the US and Russia regarding intervention in Venezuela. Secondly, how in turn, the approaches can explain why the UN security council is unable to agree about an intervention. With the starting point that one should aid people in hardship and as the popula

The PID controller is by far the most popular controller for process control in industry today [Åström and Murray, 2008]. The combination of its relatively simple usage and its satisfactory results within several areas has gained its popularity [Visioli, 2006]. However, the tuning of the controller is crucial. An automatic tuning method was developed by [Åström and Hägglund, 1984] in the mid-eight

Insect monitoring has earlier been a manual, tedious and time consuming task that is impossible to do in real time. Thus there exists a need for a real time automatic insect monitoring system for counting and classifying insect for use in scientific research and pesticide spraying control. One approach to automatize this is using LIDAR to detect insects. In this thesis it has been explored how to d

Research Problem: Existent literature has predominantly focused on applying the concept of CSR on large corporations, disregarding the role of CSR in startups despite the fact that CSR related aspects especially in relation to sustainability provide a fruitful avenue for new ventures to base their competitive advantage on. Investigation of the link between CSR and startups is needed since emerging

Med kriser och konflikter i Europa ökar intresset för självförsörjning av mat och energi, och viljan att fasa ut fossila bränslen. Skåne, med sina bördiga marker, är bland de regioner i Sverige som har bäst förutsättningar att bidra med både mat och energi från jordbruket. Men medan behovet av råvaror från jordbruket ökar, så förblir tillgången på åkermark begränsad. Konkurrensen om råvaror från jBioenergy derived from agricultural biomass has potential to phase out fossil energy sources while strengthening the bioeconomy. To estimate the agricultural sector's potential to meet the rising demand for renewable energy sources, it is crucial to understand what motivate farmers to sustainably increasing agricultural feedstock production. Through eight semi-structured interviews, and online

Sustainable development is a widely discussed concept, and it is needed because the world is facing a massive global challenge of climate change. Sustainable development is envisioned as an all-inclusive concept of three dimensions; environment, economy, and society. However, there are trade-offs between these three dimensions. Thereby, there is a need for an enhanced understanding of the relation

Worldwide inequality in the circulation of vaccines during the outbreak of the COVID-19 pandemic re-ignited the ever-existing turmoil between rich, developed nations and poor, developing nations on the role of intellectual property (IP) against the fundamental right to health. The World Trade Organization (WTO) and the World Health Organization (WHO) contribute to making medicinal products and dia

By partly replacing the use of primary energy sources with waste heat recovery, climate and environmental goals for the future will be closer at hand. This thesis investigates the waste heat potential of Alfa Laval's vacuum brazing furnaces in Ronneby and alternative ways of integrating the furnace's waste heat into the building's HVAC system. The main challenge was the low-temperatur

This study aims at investigating the thematic patterns in media presentations of Swedish communal social services and the social service workers: how is the media discussion created and established? Which areas are paid the main attention? How is the field being portrayed in media? The study is based on a material found in Swedish newspapers published under a three-month period in the end of 2014.

This thesis studies the use of GIS applications to derive adjustment figures for the terrain factor in property valuation tasks. It aims at suggesting a quantitative approach alternative to evaluate the terrain factor as opposed to traditional methods and current industry practices where terrain is qualitatively judged based on visual observation at site and subjected to individual opinion. In th

EU competition law is the safeguard of the functioning of the internal market, and not many fields of law other than patent law can delimit the scope of competition law. A patent’s value is based upon an exclusive right to the invention and product as protected by the patent. The value stems from the monopoly to the market, namely, an exclusiveness to produce, market, offer and sell the product fo

In this study the willingness to pay and conformity-seeking behaviour of Swedish consumers when purchasing fair trade coffee were examined. It was conducted through a conjoint analysis on data collected from two different questionnaires; one that presented objective information on fair trade, and one that linked fair trade to aspirational cues. The results indicated that ethical claims of fair tra

Estimation of GPP in Sudan using the evaporative fraction as water stress factor The Gross Primary Production "GPP" quantifies the amount of carbon entering an ecosystem. It is an ecosystem service since it is a source of energy for all organisms and it is estimated to reduce atmospheric CO2 in about 123 Pg C per year at the global scale. Therefore, the improvement of estimation methods
