OTEC-Ett energialternativ för enhållbar ö

Ocean Thermal Energy Conversion (OTEC) is a technology that utilizes the temperaturedifference in oceans between the warm surface water and the cold water at 1000 m depthto produce electricity. The purpose of this report is to investigate if OTEC with its synergiescould become a commercially feasible energy solution for a small island. A literature reviewis conducted to explore the different OTEC technologies and to what extent the threesynergies; fresh water, air conditioning and aquaculture, could be used. In order to calculatethe profitability of these synergies there is also a study conducted on the conventionalmethods and cost of fresh water production, aquaculture and air conditioning. A model is setup using a scenario of a small tropical Island with population of 100 000 people.

Organizing for value creation : a corporate perspective on urban farming

In the year 1800, about 5 % of the world population lived in cities (World Wide Fund for Nature, 2012, 3). Today that number is about 70 % in Europe and North America, and in 2050 it is expected to be 86 % in the developed world and 67 % in the developing world (www, UN, 2009). In addition, the global population is expected to increase with 2.2 billion people until 2050. As a result of the population increase more food has to be produced which requires more transport from the countryside to the cities. However, this flow of resources faces some difficulties.

"Stolta och starka" : Resandefolket

This is a study of a group of Swedish travellers, and of the traveller community, a marginalized group named 'tattare', skojare, tavring, knävling, dinglare, resande (Gypsies, pikeys, tinkers, travellers), whose origins and history are unknown to most people.The purpose of the study is to find out what it is like to be a traveller and look at the culture of travellers, in older times and today. I have focused particularly on the women's situation within the culture, in the past and present.The study is based on interviews with 4 persons, from the traveller community, one man and three women. During the interviews other travellers joined and participated in the discussions and the reasoning.My conclusion is that the traveller community is a group, which has been subjected to severe abuse by authorities, but still managed to preserve their culture. The interviewed travelers share a culture, in which women play a prominent role as breadwinners, for the family cohesion and in raising the children. Functions that gives women the role of culture bearers, meaning that it?s through women the culture is carried onwards..

Optimering och validering av PCR-metod för diagnostik av svampinfektioner i nagel

Nuvarande metoder för att diagnostisera svampinfektioner i nagel är långsamma och troligen ganska okänsliga. Diagnostik görs vanligen genom direktmikroskopi och odling på svampsubstrat. I ett försök att minska analystiden och att öka känsligheten användes i denna studie realtids-PCR (Polymerase Chain Reaction) för att påvisa dermatofyter. Optimering och validering gjordes av en PCR som var generell för dermatofyter och en PCR som var specifik för Trichophyton rubrum. Optimeringen innefattade annealingtemperatur, Mg2+-koncentration och primerkoncentration.

Simulator för el- och värmeproduktion : påverkan på ekonomi och miljö

In this project a simulator has been developed (in C++) with the purpose of illustrating how changes in environmental regulations, tax levels and other policy measures affect the composition of an energy system. The aim of the project was to investigate how energy companies? investment strategies are affected when changes in economic and environmental conditions occur. A standard scenario has been created based on current Swedish conditions, but the user can create new scenarios and set parameters freely. The user is tasked with building power plants to supply the city/region with district heating and electricity during a pre-set number of years. When the simulation is finished the result is graded in the following categories: economy, environment and quality. To evaluate the simulator three scenarios were created (?early 20th century?, ?reduced environmental control? and ?future?) in addition to the standard scenario and these were compared with each other by examining how a select group of power plants perform under the given conditions.

Konstruktion av en autonom vindstation

Construction of an autonomous wind station was a project with the goal of creating a product that could collect wind data from a sensor and then transfer this data to a server wirelessly over the GSM network. The device would be powered by batteries and solar cells and function fully without requiring external power supply. This required that a small computer was constructed and programmed to store and send data at predetermined cycle times and programming of a server that received the sent data. The project also required optimization of power consumption and dimensioning of solar cells and batteries based on this. The construction of this station demanded research both for the selection of hardware and programming software. The computer was based on a microcontroller and a GSM module that sent the data over the 2G network.

Hjälp! Eleven sa svartskalle! : En kvalitativ intervjustudie om hur lärare bemöter främlingsfientlighet i klassrummet.

In a multicultural society such as Sweden opposition between different ethnical groups can be hard to avoid. In the educational arena there is legislation and there are guidelines that aim to avert any kind of xenophobia directed at individuals or groups. As teachers occupy the end point of the educational chain the execution of these guidelines is for the most part left up to them.This paper aims to study how teachers handle situations where xenophobia is present and if so how they work preemptively against it. It also takes a closer look into the notion of professionalism within the teacher force with the aim of trying to answer whether teachers reach the requirements of professionalism. To do so we apply Gunnar Berg?s definition of the term 'professionalism' together with other scholars' thoughts on the subject.

Detektion av Trichomonas vaginalis samt Mycoplasma genitalium med multiplex realtids-PCR : En prevalensstudie i Jönköpings län

Beställningsfrekvensen för detektion av Trichomonas vaginalis samt Mycoplasma genitalium i Jönköpings län är låg jämfört med den för Chlamydia trachomatis och Neisseria gonorrhoeae.  Både T. vaginalis och M. genitalium har associerats med infektion av humant papillomvirus (HPV) samt kan bland annat orsaka salpingit med infertilitet som potentiell komplikation. Patogenerna har även beskrivits öka risken för transmission av HIV. Syftet med studien var att detektera T.

Solenergi i Norrra Djurgårdsstaden

This report will examine various solar energy technologies in order to decide if they could be applied in the Royal Seaport. The Royal Seaport is a Swedish urban district under development in Stockholm, with the goal of becoming a sustainable district. Two main techniques, solar collectors and solar cells, including sub-categories, are addressed in this report. Another sub-category, a hybrid system, will also be mentioned. The main difference between solar collectors and solar cells is the type of energy produced by the system.

En global logistikkedja : En deskriptiv studie av doktriner och på den nya globala Försvarsmaktens krav av logistikkedjan vid strategisk nivå

Den nya globala försvarsmakten ställer nya krav, inte minst på logistikkedjan där avstånden ökar och förutsättningarna för insats inte är lika klara som under det kalla kriget. Syftet med uppsatsen är att undersöka vilka krav ur en doktrinär synvinkel som kan komma att ställas på logistikkedjan på strategisk nivå kopplat till en strategisk rörlighet vid en framtida Svensk insats. Som empiri i uppsatsen används de doktriner och reglementen som finns i Sverige och i NATO som avhandlar logistikkedjan på strategisk nivå och strategisk rörlighet. Samt en fallstudie från Operation Iraqi freedom för att exemplifiera de krav som kan komma att ställas på logistikkedjan på strategisk nivå. Uppsatsens metod är deskription och fallstudie där fallstudien exemplifierar de problem som kan komma att uppstå.

Vägen till en levande lanthandel

AbstractA general store is a grocery store that is located in the countryside. In today's modern society, it is difficult for general stores to compete with the supermarkets and discounters in terms of price and supply. The purpose of this thesis is to create an understanding of both the rural merchants and its customers? perspective on a well-­?functioning general store. We have conducted a case study of three general stores where we interviewed the merchants about how they do to please their customers? needs and identify key elements of a well-­?functioning general store.

Utvecklingens dimensioner: utifrån ledarskapsutvecklarnas perspektiv

The market for management training programs is growing and the supply of the service is increasing and getting further diversified. A consequence is a market with a wide variety of definitions of the very concept of development, and subsequently a wide variety of practices and methods to achieve development. The individuals that are subject to these programs seldom know what they are purchasing, or what to expect. When assuming a transfer of the developers view on development to the subject, a need for a greater understanding of the concept arises. The purpose of this thesis is to understand what views on development do exist among management trainers and map underlying dimensions of the views to increase the understanding of the concept of development.

Lärare och informationssökning. En undersökning av lärares utsagor kring sin informationssökningskontext

The purpose of this thesis is to reach a deeper understanding of the context of teachers? information seeking. Research in the role of the library in a learning perspective is in demand. To reach our aim we investigate what teachers say about their experiences of the user training during their studies and what effect it had on their information seeking as teachers. We interviewed four teachers and analyzed the transcripts of their sayings about their experiences of their information seeking during their education and a teaching profession.

Sökarkyrkan; Marknadsförd religion mot den postmoderna sökaren? -Hur och varför ett fåtal innovativa religionsproducenter förändrar det amerikanska religiösa landskapet

The controversial phenomenon of ?seeker-oriented? megachurches are currently transforming the American religious landscape. These churches, some housing up to 30,000 worshippers every week, are targeting religious seekers as their primary objective. Their success in attracting and converting those who usually wouldn?t even think of attending church can in large parts be explained by changes in liturgy, the removal of visible theological discussion and use of shopping mall styled buildings, designed to make the religious seeker feel like home.

Äldres upplevelser av apoteksprivatiseringen : Konsekvenser efter privatiseringen av de svenska apoteken

ABSTRACTThe privatization of pharmacies in Sweden took place in 2009, in part with higher availability of medicines as justification. For a good adherence, the patients needs a good availability of medicines from pharmacies. The aim of the study was that two years after the pharmacy reform study older people?s opinions on drug supply and pharmacy services, and which pharmacy chains they know about and use. The method used was a quantitative cross-sectional study and was conducted using questionnaires.
