Cykelparkering i stadsmiljö : en redogörelse för cykelparkeringens komponenter
In recent years many cities have seen an increase in bicycle traffic. This is a development that benefits both the environment and the individual cyclist. When the need for bicycle parking is not met several problems arise such as an increase in bicycle thefts, jammed sidewalks and a decreased interest in using bicycles. My aim with this paper has been to answer the question of how to create parking facilities in an urban environment based on cyclists' needs. Through a literature survey, following the method "Trattmodellen" (the funnel model) the question has been answered and divided under the headings cyclist, bike, bicycle racks, bicycle garage and bicycle operators and hosts.

The change encountered several problems where the correctional supervisor was percieved to act unsurely and indecisively whilst parts of the staff constructed and implimented several courses of action to prevent the process of change..
Feminism till höger och vänster? : En jämförande studie emellan Sverigedemokraternas och Kommunistiska Partiets feministiska teori och praktik
The aim of this Master?s thesis is to investigate if the reading habits of teacher students are influenced by merit and descent. The empiric material consists of six questionnaires answered by students at the teacher training with Swedish at the upper secondary school as their first topic. The questionnaire comprised questions about reading habits in the childhood and today and information concerning merits and descent.Pierre Bourdieu?s sociological ideas about cultural capital transmitted from parent to child and the concept of habitus are used as a theoretical framework regarding descent.
Transporttider för vatten i närområdet till en vattentäkt : spårämnesförsök i en isälvsavlagring
When establishing a groundwater protection area it is of great interest to be able to estimate the transit time of the groundwater from different places of the aquifer to the withdrawal well. These estimates can be uncertain due to heterogeneities in the aquifer. As a part of the work to develop methods for a more certain delineation of protection areas, a tracer test was performed in an esker located 25 kilometres NW of the town Uppsala.The purpose of this master thesis was to perform, describe and evaluate the tracer test. Travel times from the tracer test should then enable comparison against stochastic simulated travel times of the groundwater in the area.Three dyes (rhodamine WT, uranine and naphtionate) and a salt (NaBr) were used in the tracer test. The tracers were injected in four different wells located 25 meters from a pumping well.

A systematic review.Author: Josefine Lindqvist, Robin Järnmark, Mathilde OhlinSupervisor: Mette AxelsenExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: 2014-04-09BackgroundResearch indicates that dairy products seems to have a protective impact on the incidence of cardiovascular disease regardless fat content. Paradoxically the Nordic nutrition recommendations recommend an exchange of full fat dairy product to low-fat dairy products.ObjectiveThe aim of this review is to investigate whether the variation in fat content of dairy products have any bearing on the onset of cardiovascular disease. With regard to common risk markers for cardiovascular disease the outcome measures hypertension, hyperlipidemia and weight gain is examined.Search strategyThe searches were made in the databases Medline (23/1-14) and Scopus (6/2-14).Selection criteriaRestrictions: Human Studies, Adults, Randomized Controlled Trials, English.Data collection and analysisTwo RCTs were included. Validation of the separate studies was performed with SBU's review template for individual studies and GRADE was used for summarizing the evidence of outcome measuresMain resultsThe two included studies examined the outcome measures blood pressure, weight and blood lipids.
Släpslangspridning av gödsel, kan det löna sig? :
I have chosen to work with drag hose system and try to find an alternative to spread manure with a usually tank system, see if you can make a profit and what advantage and disadvantage the system has.
The purpose whith the project has been to try to make a system that can spread manure at better occasions than farmers do today and above everything make a financial addition. Today it is just a heavy work and takes a lot of time.
I have counted on investment costs and carefully examined what equipment you need. I have not the technical details in my project, I have just tried to understand how it is to spread manure with drag hose system today.
What is drag hose system?
You put a hose in your manuretank, connect it to a pump that is driven by a traktor or stationary engine. You place a hose that reach the field were you are going to spread.
Mask + löv = jord : En undersökning om sexåringars förmåga att utveckla sina ekologiska tankar
SammanfattningSyftet med den här undersökningen är att ta reda på hur barns tankar kring ekologiska processer kan utvecklas, samt att ta reda på vad i undervisningen som anses vara avgörande för att förmå barn att utveckla sina ekologiska reflektioner. Kvalitativa intervjuer och ett undervisningstillfälle ligger till grund för undersökningen. Därefter sammanställdes och kategoriserades barnens ekologiska processtankar. Resultatet av undersökningen visar att förutsättningen för utvecklande undervisning, är pedagogens kännedom om barnets individuella erfarenheter. Det är utifrån dessa som barnet tar emot ny kunskap och sedan kopplar ihop den med tidigare upplevelser.
Sjuksköterskans upplevelse och hantering av stress på en akutmottagning
SUMMARY The purpose of this study was to explore how nurses in the emergency department experience and cope with stress in their workplace. The study had a qualitative, descriptive approach and was based on nine individual, semi-structured interviews. They were then processed using content analysis. The content analysis of interviews resulted in two categories, "the nurse's experience of stress," "the nurses coping with stress." Together, the categories highlighted how nurses experienced stress during and after their shifts. The study showed clearly that all nurses experienced and coped with stress in their daily work activities..The authors noticed that stressful time for the nurses were repeated at each session and were similar in character.
Visualisering av produktionseffektivitet : Utveckling av ett verktyg för övervakningav avbrott och presentation av TAK
Many companies do not register all the stops that occur in a production plant, it often takes longer to report than to fix the problem. If no problems are registered, you cannot trace where the problems arise.This master thesis was performed at AcobiaFLUX and they have noticed an increased demand from their customers to trace problems raised in their processes. The aim of the thesis was to find out how a tool to monitor a process best could be developed. Then the most essential from the theoretical base was developed into a useful tool for operators. For the operators to know if the process utilizes the full capacity of a process, the tool presents a measure of the Overall Equipment Efficiency, OEE.
Flavan-3-oler och endotel -dysfunktion
Background: Flavan-3-ols are polyphenolic phytochemicals belonging to the flavonoids. Flavan-3-ols are present in many higher plants and are particularly concentrated in e.g. Camellia sinensis (tea) and Theobroma cacao (cacao) and have got attention due to their antioxidative capacity. Many studies have been able to associate flavan-3-ol-rich foods to improved endothelial function. The aim of the present work is to review the scientific literature and evaluate the evidence for positive effects of flavan-3-ols on endothelial dysfunction in humans.
Method: Scientific articles describing intervention and observational studies about flavan-3-ols and endothelial dysfunction, were searched for on http://www.pubmed.org.
1553-Simulator. In-/uppspelning av databusstrafik med hjälp av FPGA
At Saab Aerospace in Linköping, components for measurement systems to the fighter aircraft JAS 39 Gripen are developed. In this activity you sometimes want to record the traffic transmitted on the data busses that connects different sys-tems. This traffic on the data busses is using the military standard MIL-STD-1553. This project has aimed to create a system for recording and sending 1553-data. The system is used on an ordinary personal computer, equipped with a recon- figurable I/O card that among others has a programmable logic circuit (FPGA).
En stabs nätverkstrafik : En analys av användningen av datornätverkskapacitet i en operativ stab under övningen VIKING 11
FM köpte satellitkapacitet för närmare 20 miljoner kronor under 2014 för utbildning, övning och internationella operationer. Enligt HKV räcker dock inte upphandlad kapacitet för att täcka behoven ute hos förbanden.Syftet med denna studie är att ta reda på mer hur kapacitetsanvändningen ser ut vid en operativ stab utifrån deras arbete och därigenom se om det finns någon militär nytta att vinna kopplad till kapacitetsanvändning.Utgångspunkten för arbetet är insamlad information om datornätverkstrafiken i de olika nätverken. Detta kvantitativa data jämförs med stabens arbete utifrån kvantitativ och kvalitativ data i krigsdagbok, styrdokument och deltagande studie.Studien visar på att kapacitetsanvändningen ej är relaterad till stabens arbete utan snarare är kopplad till när personal är på plats och personalens internetanvändning. Studien pekar på att det kan finnas en potential att få mer militär nytta, dock måste mekanismer för prioritering i nätverket införas och vidare studier avseende trafiken genomföras..
Förslitning av fräsverktyg
Sweden is dependent on secure sea transport. Shorter disruption of imports of fuel and crude oil can be managed with an emergency stock, but a prolonged halt in imports creates problems. For industry, the vulnerability is greater. Fragmented production chains in combination with expenditure reductions in inventory causes a dependency on proper transport of intermediate goods in the manufacturing industry. A lengthy disruption thus involves disruption of production for both domestic consumption and for export goods containing imported parts.In order to secure shipping routes with a limited number of vessels, Mine Counter Measures (MCM) capacity is required, and according to the Armed Forces, developed with new sensors and autonomous vehicles.
En topologisk representation av en polygon;det rakkantiga skelettet
The aim of this thesis project is to produce an algorithm for finding a topologicalrepresentation of a polygon, called a straight skeleton, using floating pointarithmetic. Various straight skeleton algorithms are examined and discussed witha focus on time complexity and one is chosen for implementation. This implementationis then compared with the open source library CGAL with regards torunning time. The result is an algorithm which is based on an algorithm by Felkeland Obdrzalek and which, for polygons with more than five thousand vertices andthree significant digits representing points, runs around 25% faster than CGALsimplementation. Complications regarding the use of floating-point arithmetic arealso discussed..
