Onlinedejting via lokaliseringsapplikation : En studie om hur mobilapplikationen Badoo används ute på krogen
Online dating and ?People nearby applications? (PNA) has become more popular in today?s society. With PNA you can easily find people who are nearby you that you can socialize with and maybe even meet. In this paper we study the mobile application Badoo and explore how it is used for dating in clubs in Stockholm through observations that we participated in. We also had a group interview with five Badoo users about their usage of the application.
Competition for forest fuels in Sweden : exploring the possibilities of modeling forest fuel markets in a regional partial equilibrium framework
This thesis project focuses on the need for better tools for analyzing competition for forest fuels in Sweden, in particular how policy measures may influence the market and involved actors in different regions of Sweden. Raw materials from the forest have for long constituted important inputs in the Swedish forest industry. Today some of these raw materials are increasingly used as inputs also in bioenergy production, largely driven by bioenergy promoting policies, and there are signs of increased competition for forest fuels which may have various and uncertain effects on the industries in question. The thesis project explores the possibilities to adapt previously used forest sector equilibrium models into a new model suitable for analysis of Swedish forest fuel markets, called the Swedish Forest Sector Trade Model (SFSTM). The approach takes into account regional differences in supply and demand for 23 types of products produced and/or used by eight types of producers, plus consumers, in five different regions (four Swedish and one international).
Hållbarhetslivscykelanalys på kakel och klinker : Analys av vägen från vagga till grav ur ett hållbarhetsperspektiv
In this report two Sustainability Life Cycle Assessments are carried out for two types of tiles for Riksbyggen, to contribute to a sustainable urban transition. Sustainability Life Cycle Assessment involves performing a life cycle assessment based on four principles based on scientific research and presented by the non- governmental, non-profit organization, The Natural Step. The principles concern raw materials, chemically produced substances, degeneration of nature and social conditions.Origin of products, manufacturing sites and manufacturing procedures were initially completely unknown and much of the work has consisted of finding the entire cycles, understand manufacturing processes of ceramic tiles and evaluating what materials and what type of energy sources that are required for the production. A socially sustainable perspective has been of high relevance alongside an ecologically sustainable perspective.The report begins with the basic underlying facts and the purposes of this investigation and that the reasons why Sustainability Life Cycle Assessments are carried out are to provide Riksbyggen and the own workers with documents presenting Riksbyggens ideas regarding sustainability and to hopefully get the ideas further down in the supply chain. The methods used to fulfill the investigation are presented and scientific facts about LCA and ceramic building materials are reviewed.
The effects of Gotland pony grazing on forest composition and structure in Lojsta hed, south eastern Sweden
Livestock animals affect their environment in a number of different ways, mostly through grazing and trampling. This study focused on the effects of Gotland pony grazing on forest structure and diversity, and the impact on ground cover. To compare the fenced and grazed area with a reference area outside the enclosure a number of transects were used. The study showed that there was no significant difference in height structure and diversity between the compared sites; however, there were a significantly higher proportion of damaged trees inside the enclosure. The ground cover variables showed a higher amount of bare soil, plant litter and wood-rush (Luzula sp.) inside the enclosure whilst grass was more frequent in the reference area.
Självgående renslastare till sockerbetor :
Our greatest interest within crop farming is to grow sugarbeets, that?s why we want to
write about something new in this sector. We heard that a new concept had come to
Sweden so we wanted to find out everything about this machine.
This new technique was a self-propelled cleaning loader for sugarbeets. This machine is
supposed to replace a loader and a cleaning machine when the sugarbeets is going to be
loaded, cleaned and delivered to the sugerbeet factory. The cleaning loader picks up the
sugarbeets with rollers from the pile, which is placed close to the road.
Brikettillverkning på gårdsnivå :
In my work I have chosen to examine the profitability for small scale production of hemp briquettes. My study also includes a review of which briquette technique that is the most common one among small scale producers. The reason that I have chosen this subject is because of the discussions about climate and energy that we face almost every day. I also think the subject is extra interesting in these days when the grain prizes are at a historic high level.
In order for me to achieve a reliable report, a hemp and briquette producer has given me the actual data from his farm. In that way I have been able to make my calculations from a concrete perspective.
Ekonomi i vallfrödominerad växtföljd :
This is a project about how you grow timothy seed and red clover seed successfully. The main part is about economic analyse to see if it is any economy by growing leyseed.
There are lots of things to be aware of to get all the costs in your economic analyze.
Timothy
Timothy seed is planted on 4400 hectares in Sweden. It is possible to grow timothy seed in the south part of Sweden. Timothy is very sensitive for dry weather in spring and in the beginning to summer. Timothy gives acceptable harvest of seed for about three years.
Red clover
Red clover is also sensitive for dry weather and is suitable to grow in the south part of Sweden.
Svampar associerade med raps : betydelse för uppkomst och grödetablering
Oilseed rape is an important crop in Sweden and is grown on about 90000 ha today. The interest in oil seed pro-duction is increasing because of growing demand and high prices for oil seed both in Sweden and Europe. However, an increased intensity in the oil seed production can bring higher risk of yield losses due to fungal diseases. The purpose of this study was to investigate what different fungi are associated with oilseed rape under field conditions and if their incidence is correlated to crop establishment problems.
This study was carried out in three parts: 1) investigations on fungal community structure in roots and rhizosphere soils from young spring- and winter rape plants sampled in failed respectively good establishment patches in four fields, 2) investigations on the pathogenicity of fungi isolated from oilseed rape in controlled environment and 3) investigations on the effect of different fungicide seed treatments on germination and early plant development in a field soil naturally infested with damping off- and Verticillium wilt pathogens.
The studies on community structure using a combined approach of standard fungal isolation techniques and DNA based methods revealed a high fungal diversity in three out of four studied fields of spring rape and winter rape. For some unknown reason, very few fungal species were identified from the fourth field.
Bibliotekariestudenter - informationsnissar eller kultursnubbar: vem söker till bibliotekarieutbildningarna i Lund och Umeå, och varför?
This thesig will portray the different types of students at the programs of library studiesin Lund &d Umeå.The study is based upon quantitative information gathered from a survey, which wasdistributed to first-year students in Lund and Umeå. The survey was followed by qualitativeinterviews with four students, and with the director of studies from each school.The study shows that the programs, as we11 as the students, are very similar, althoughthere are some minor diferences. It seemed that the students at Umeå were moreinterested4n culture than those at Lund.A certain connection between the aim at information and the ownership of a computercould be detected. The sex of the students played a major part in their choice of education.The attractors and facilitators, used by Lortie in his study, could also be appliedto the students at the program of library studies in our thesis..
Att mäta fattigdomsbekämpning - En studie av social performance-rapportering inom mikrofinans
This study has a double purpose. First, it explores and maps out the use of quantitative key indicators in social performance reporting within a microfinance portfolio. This was done on behalf of Storebrand Asset Management, who would like to aggregate and report the social results of their microfinance investments to their customers. The study concludes that the extent of social reporting and types of indicators used varies, meaning that it is hard to aggregate data for use in further reporting. Thus, the work towards the goal of social reporting has only just begun.
Moräntäckta rullstensåsar i Västerbottens inland
The purpose of this study was to map the distribution of till-covered eskers in the inland of Västerbotten County in northern Sweden. The top layers of big eskers along the valleys of Öre River, Ume River and Vindel River were investigated through shallow digging. Findings were investigated through field assessment and soil analysis and many locations with till-covered eskers have been identified in Västerbotten's inland in this survey. The till covering the eskers has probably been transported only short distances and has its origins in glacifluvial material. The pattern is not consistent and there are areas where till does not cover the eskers.
Lokalisering av ytor för hantering av jord- och bergmaterial i Södertörn
Syftet med arbetet var att identifiera ytor inom Södertörn där det skulle vara möjligt att etablera materialterminaler för hantering av byggbranschens jord- och bergmaterial. Förhoppningen var att detta kunde bidra till ett planeringsunderlag för en samordnad materialförvaltning inom regionen. Behovet och nyttan av fler materialterminaler har börjat uppmärksammas, men inga studier kring vilka platser som lämpar sig för ändamålet har tidigare genomförts utifrån svenska förhållanden. För att ta reda på vilka kriterier som definierade en bra materialterminalyta genomfördes en intervjustudie där tio aktörer med anknytning till materialhanteringsbranschen intervjuades. Kriterierna översattes till geografisk information och implementerades i GIS-programmet ArcMAP där det konstruerades en kartbild vilken visualiserade de ytor som var lämpliga respektive olämpliga att använda för ändamålet.
Energivinst vid hybridisering av hydrauliskt system
Today's high oil prices and more stringent environmental requirements have led to that manufacturers of mobile construction equipment try to make their products more energy efficient. With this in mind a project about hybridization of hydraulic systems has been formed. The purpose of this project was to analyze the savings that can be achieved by hybridization of hydraulic systems. A reach stacker truck (Kalmar DRD450-80S4XS) were simulated in some load cases with conventional hydraulic systems and with three types of hybridized hydraulic systems. Different parts of the hydraulic systems were also analyzed separately.
Andraspråksutveckling i den mångkulturella förskolan
This thesis deals with two types of agrarian remains in relation to settlement remains; clearance cairns, low stone walls and house terraces in the area of Northeastern Uppland and the area north of Lake Mälaren, during the middle Iron Age. The aim whit this thesis is trying to get a better understanding of the relation between agrarian and settlement remains in Uppland. Three places have been chosen where these three elements are present and they are interpreted through Richard Whites concept of middle ground but also Landesque capital. The three elements have shown to be expressed in different ways in all three sites. It is possible to see two areas with different traditions, but also to see two areas that closely interact with each other, this opens up for a new discussion around agrarian remains in both areas.
Brott och straff under 1600-talets första del : En komparativ undersökning av Sjuhundra härad och Njurunda härad
The aim of the study was to investigate the crimes and punishments that were commonly occurring between the years 1601-1651, and how the distribution was between men and women represented in the court in district Sjuhundra and Njurunda district. To answer these questions, a quantitative examination of court records conducted in which the crimes and punishments have been categorized. The results that have emerged have been the basis for the conclusions issued in the essay. The results showed that the most common target types were various civil and propertycase and the most common punishments were sentenced to fines and settlements. It was predominantly men who were in the court, the proportion of women was between 13-22%.
