Matavfallskvarnar är ett smidigt sätt att samla in matavfall på. Med nya system behöver matavfallet inte transporteras till reningsverket utan kan istället lagras i tankar för att sedan köras direkt till biogasanläggningen. Här produceras biogas av matavfallet genom rötning. Biogas är en förnybar energikälla som bland annat kan användas som fordonsbränsle, uppvärmning och elproduktion. Genom att To collect, treat and use food waste is desirable in society in order to recycle and efficiently use all resources. One stage of one of the Swedish environmental goals is to collect and treat 50 % of the food waste biologically in year 2018. A useful product from this treatment is biogas, which can be used for fueling vehicles, heating and producing electricity. Biogas could be produced from food

Nära infrarött ljus (NIR) kan användas för att säkerställa djurfodrens näringsinnehåll Det är viktigt att kunna garantera att djurfoder innehåller rätt mängd näringsämnen, oavsett vilken sorts fettkälla (såsom vegetabiliska oljor eller fiskolja) som används vid fodertillverkning. Detta kan göras med NIR-teknik! För att djur ska vara välmående är det viktigt att de får i sig rätt mängd näringsämnThe aim with this master thesis was to investigate if a certain sow feed requires different calibrations in near-infrared analysis, due to if the sow feed have fish oil or AkoFeed as fat source. To investigate this, a basic sow feed mix was prepared and divided in 60 jars with 250 g in each. In 30 of the jars 0 to 15 g fish oil were added and in the other 30 jars 0 to 21 g AkoFeed were added. 2/

Title: Virtual Reality as presentation tool for architects Authors: Adrian Norlund och Lisa Rask Supervisor: Fredrik Wikberg, Department of Building Construction, Faculty of Engineering (LTH) Question formulation: - Will the audience get a better idea of an object in VR compared to current presentation techniques? - What is most useful for architects, Oculus Rift, Google Cardboard or VR room (CAVE

As society’s electricity demands increase, technical solutions and advancements are essential to meet energy needs. Solar energy is a promising source, and solar cells enable the conversion of sunlight into electricity. This study is in collaboration with Midsummer AB, a Swedish company that specializes in sustainable solar cells. The company employs a sputtering process for manufacturing these ce

In many parts of the world, people within the lgbtqi+ community are forced to leave their countries and flee to a new one. This is a consequence of legislation and societal norms that criminalize and expose the group to threats and violence. Because of this, individuals from all over the world seek rescue in Sweden and therefore apply for asylum based on gender identity and sexual orientation. The

This project uses proton-proton collision data from the ALICE experiment at CERN to investigate the differences between three ways to classify events, known as event shape classifiers. The event shape classifiers that were investigated are RT , spherocity and flattenicity. The motivation behind this is the consistent use of these classifiers to select events when investigating the heavy-ion like

Popular science summary Salinity has been identified as an important factor in governing both growth and distribution of phytoplankton in marine and brackish ecosystems. In my thesis work I investigated the salinity tolerance and growth rate of the cold-water dinoflagellate Scrippsiella aff. hangoei from an Antarctic population. The work was carried out at the Department of Biology at Lund Univer

Purpose: The purpose of this thesis is to analyze statistical- and financial measuers of hedgefund categories between 2008-2013 to see if there is a significant difference in performance between two period (recession and economic growth). The models will also analyze which category performs the best in each economical period. Method: The thesis is built using mainly a quantitative method, by col

Proteiner är något som många förknippar med mat, exempelvis kött och ägg. Proteiner finns också i kroppen och har där många olika uppgifter, bland annat att bygga upp muskler. Det finns en intressant grupp proteiner som har en oordnad struktur (intrinsically disordered proteins), vilket innebär att de inte har en ordnad tredimensionell struktur, utan kan anta flera olika konformationer. Det kan va

This report is a fire safety evaluation of Träcentrum, a school and conference center in Nässjö, Sweden. The building is divided into five sections but because of various limitations only two will be thoroughly investigated in this report. A site visit at the location was made in February 2012 to gather information about the fire protection and evacuation of the building. Targets of protection we

The Swedish Easter protest of 2011 against the losses of sickness benefits that were caused by the social policy reforms of the Swedish government was characterized by its decentralized network structure, its rapid progress and its use of the internet and social media for the spreading of information. It is the aim of this essay to use the Easter protest of 2011 to investigate how the Church of Sw

The study aimed to investigate the relationship between the leadership style of future leaders, their personality, as well as their perceived stress level. The Full Range Leadership model with a focus on the transformational leadership dimension, as well as the Five-Factor personality model were used as a theoretical basis. The study was conducted with eighty- seven participants enrolled in a Mast

Urban bosättning är vanligt i dagens samhälle och en övervägande andel av befolkningen bor i lägenheter, där ljudisolering är en viktig aspekt rörande trivseln i bostaden. Användning av smartmobiler för akustiska mätningar blir allt vanligare, men inget enkelt verktyg finns idag för att mäta och räkna ut reduktionstalet. För att räkna ut reduktionstalet behövs ljudtrycksnivå, bakgrundsljud och efUrban dwelling is common in our society today and a considerable portion of the population reside in apartment buildings, making sound insulation an important aspect regarding the comfort of urban living. While using smartphones for acoustic measurements is becoming more and more common, there is an absence of a simple tool for measuring sound reduction index. Sound reduction index is a measuremen

One of the defining features of the post-Cold War era is the growth of international migration in all areas of the world, especially in Europe, where the lift of the Iron Curtain created needs and opportunities as far as immigrants are concerned. Although a beneficial process in itself, the growth of migration to Europe was frequently a cause of various forms of conflict, which in the social scien

The aim of this Master's thesis is to discuss and analyse co-operation between public and academic libraries. The political changes that were initiated during 2004 have come to alter the conditions for Swedish libraries. The Swedish library law was changed at the 1st of January 2005 and co-operation between libraries is now statuary even if there is no description of how the new mission is to

The purpose of this study was to examine how social workers, in the social services department of economical aid, are affected by the increasing number of clients. More specifically we focused on how the social workers job situation as a whole, how the feelings of their work and the ability to reach the goals of the organizations was affected by the changing circumstances. To examine this we used

The number of species classified as red-listed has increased by 11% between 2015 and 2020, with beetles and butterflies being especially affected. Among these are the vulnerable longhorned beetle (Stictoleptura scutellata) and the endangered false blister beetle (Ischnomera sanguinicollis). Forty percent of all known species in Sweden are dependent on hostplants, indicating the value in mapping po

Purpose: The purpose of this study is to explore how brand managers align their brand identity within online brand communities where the communication is shared in order to create a reinforcing point of contact instead of a source of mixed messages. Problem: With the increasing usage of the internet, brand managers are today forced and challenged to align and re-enforce a brand’s identity online w
