Nanowires provide interesting features for photovoltaic applications. Materials with desirable band gaps can be combined into heterostructures with very little strain and with a fraction of the material consumption seen in conventional solar devices. Moreover, nanowires show outstanding optical absorption and InP and GaAs nanowire solar cells have been shown to reach efficiencies of 13.8 % and 15.
What The site are soon to be confronting large changes when re-opening a train station as a part of a circle line in Malmö. Today the site forms a rift through the city. The barrier effect by this rift is amplified by the five meter elevated train tracks passing through the site. This part of the city has had little changes over the years and have many historical values and elements How By enhan
In this study, we have investigated some mechanisms used in nature to protect membranes and other self-assembled biomolecular structures against changes in hydration. One common mechanism used by many living organisms is the accumulation of small polar solutes with low vapor pressure that stabilize the cell membranes in cases of osmotic stress.1 These molecules are known as osmolytes. Among other
Uppsatsens syfte är att undersöka hur associationer till reklam, som frångår heterosexuella normer, skiljer sig mellan generationer. Med en hermeneutisk fenomenologisk metod har en kvalitativ uppsats genomförts. Uppsatsens forskningsansats är abduktiv. Analys och slutsatser bygger på teorier som har hämtats från böcker, vetenskapliga artiklar och hemsidor i kombination med empiriskt material inhäm
Under de senaste tio åren har den rekommenderade utformningen av VA-schakter förändrats till att bli bredare och säkrare. De metoder som tidigare använts ifrågasätts i denna studie då de alternativt är utdaterade. Syftet med arbetet har varit att undersöka vilken maskintrupp som är bäst vid de nya förutsättningarna. De maskintrupper som har analyserats skiljer sig åt genom att en långgrävare ersät
Klimatförändringen medför att allt mer frekventa och kraftiga skyfall belastar den ständigt växande staden. Urbaniseringen tillsammans med förtätningen av stadsmiljöer har lett till att sådana regn får allt större konsekvenser. Detta beror på den ökade andelen hårdgjorda ytor som hindrar nederbörd från att naturligt infiltrera. Istället bildas större volymer ytavrinning som måste ledas bort för atDue to climate change more extreme precipitation is expected to strike the constantly growing cities around the world. Urbanization along with densification of urban areas magnifies the impact of heavy rainfall. These two processes have increased the amount of hard surfaces that prevent precipitation to naturally infiltrate, and therefore result in larger amount of surface runoff that must be dive
Standardization plays a key role in modern industries. Standards provide compatibility and interoperability of products, thus increasing their value for consumers. In fact, standards go beyond that and positively affect market integration, consumer safety, environment issues etc. The European Union actively supports standardization run by Standard Setting Organizations. These organizations operate
This qualitative study aims to contribute to a deeper understanding of how companies in the fashion industry communicate sustainability through the label on the garments. The purpose of the thesis is to examine how the knowledge gap between companies and consumers regarding sustainability issues, could be bridged using the label. Further, the possibilities of using the label as a tool to achieve a
Uppsatsen uppför en historisk överblick över hur En dåres försvarstal lästs och belyser hur den kritiska diskursen förändrats. Förklaringsmodellen utgår från Bourdieus fältbegrepp vilket hjälper påvisa att positioneringar inte sker naturligt utan i relation till varandra såväl som till de rum som står och gjorts lediga på det så kallade fältet. Uppsatsen undersöker läsningars förhållningssätt till
I en värld där klimathot och resursbrist har växt fram till ett allt större problem på världsledarnas agenda har vikten av hållbar utveckling identifierats som en nyckelfråga i vägen mot en bättre framtid. En metod för detta är industriell symbios, som innebär att olika företag och organisationer gemensamt utnyttjar energi, nyttigheter, material eller service, för att på ett innovativt sätt skapa In a world where climate change and resource scarcity have grown to some of the main issues on the world leaders’ agenda the importance of sustainable development has been identified as a key challenge in the path towards a better future. One method for this is industrial symbiosis, where different entities collaborate over energy, utilities, materials or services to create value and lower cost an
Tourism has been a fief industry for state power in Jordan, used as state-building tool and hard-currency earner. However, the country’s socio-economic structure and the current regional conflicts have hindered its development as the expected economic engine to achieve Jordan’s independence from foreign aid. This work looks at a collective identity created around outdoors and adventure sports in J
The demand for renewable energy is constantly increasing and in order to compete with other sources of energy the wind energy output has to increase. The power output from wind turbines are highly dependent on the swept radius of rotor blades. Increasing the length of the rotor blades will increase the weight of the blades, resulting in higher demands of the structural performance, but also introd

Den vanligaste typen av lyftbord inom industrin är uppbyggda med en saxlift som får sin vertikala rörelse med hjälp av hydraulcylindrar. Enligt standard SS-EN 1570-1 finns det i vissa situationer krav på att en mekaniskspärr ska finnas som förhindrar lyftbordet från att sjunka. Existerande produkter som företaget Marco AB utvecklat och säljer finns, men antingen kräver de ett omkringliggande schakThe most common types of lift tables in the industry is structured with a scissor lift that gets its vertical movement by means of hydraulic cylinders. According to the standard SS-EN 1570-1, some situations demand that a mechanical lock must be provided to prevent the table from sinking. Existing products that the company Marco AB have developed and are selling are available, but either require a
The current Lambda Cold Dark Matter cosmology predicts galaxy growth by hierarchical merging, leading to galaxy substructure like tidal streams and dark matter subhalos devoid of stars. The goal of this thesis is to investigate whether tidal stream-subhalo interactions can leave observable gaps in the streams, and at which rate this might happen in a galaxy like the Milky Way. The stream-subhalo i
Women have been regarded as a disadvantaged group in Nepal (Aoki & Pradhan, 2013), because of the limited opportunities in these areas, women residing in rural parts of Nepal such as, Kudari VDC in Jumla, are particularly vulnerable. The women in Jumla normally are involved in daily household jobs like cooking, cleaning, washing, feeding the cattle etc. The Maoist insurgency (about a 10 years
The automotive industry is a field of enormous competition. Customers and regulations demand economical and sustainable products. To achieve maximum efficiency, engine systems require detailed control. To increase the accuracy of the models that describe the combustion process, a demand has arisen at Scania for an exact prediction of the combustion chamber volume. During engine operation, the com
För att begränsa den globala uppvärmningen krävs en omställning mot en klimatmässigt hållbar livsmedelsförsörjning. Konsumtionen av kött och mejeriprodukter, som idag står för en stor andel av matens klimatpåverkan, behöver minska till förmån för mer resurseffektiva vegetabiliska livsmedel. För att kunna komplettera eller ersätta animaliska näringskällor berikas många växtbaserade produkter med inIn order to mitigate the global warming, a transition towards a sustainable diet is required. Such a transition includes reduced consumption of meat and dairy products, by substituting these with more resource efficient vegetable-based products. In order to meet the nutrient content of animal foods, vegan products are often supplemented with artificial vitamins and minerals. Few studies have inves
