Utökning av mätområdet för turbinverkningsgraden på avgasturbo

The Goal with this Master of Science thesis is to expand the possible turbine efficiencymeasurements on an exhaust turbocharger. It was done as a part of the CICERO competencecentre. To feed the turbine with air a special flow rig has been used. Instead of loading theturbine by just restricting the compressor flow a docking system for an electrical dynamometer isdesigned to use the dynamometer as an additional loading source. By using an electricaldynamometer as loading device for the turbine, measurements are not depending on compressorperformance.A large part of the work consists in designing accessories for the dynamometer.

Steget från tanke till handling : En studie om viktiga faktorer för nyföretagande bland kvinnliga studenter

Women who support themselves through self-employment are relatively low compared to men, in Sweden. Women make up around 30 percent of newly started enterprises. The Swedish government considers that the Swedish economical growth would increase if there were more companies. Through encouraging women to start enterprises to the same extent as men, Sweden can increase growth rate and create more employment. Despite all efforts being made, advances are not really reached.

Produktionsoptimering av Kv. Hunden

For many years, there has been a housing shortage in Sweden. Many have been expecting a construction boom in the housing sector, but that has yet to arrive. With the current legislations and guidelines surrounding modern, energy efficient housing; production costs have increased dramatically in recent years. As a result, having a negative effect on housing production despite the high demand for homes.This exam work is carried out on a construction project of Sjötorpshus AB and its purpose is to evaluate how to optimise the construction process for the production of a new residential settlement, "Kv.Hunden", located in Katrineholm. In an interview with the company's MD, Pär Knutsson, four main issues were defined to focus on.

Kraftanalys och framtagning av mätanordning för vertikala vindkraftverket Lucias bärarmar

The project contains a force analysis of the vertical axis wind turbine Lucia's supporting arms and a measuring device to experimentally measure the forces is made. The forces between the supporting arms and the tower are calculated theoretically and then simulated by a computere. A measuring devise is then designed to measure the forces experimentally. The forces acting on the attachment between the supporting arms and the tower is primarily the centripetal force, gravitational force and the aerodynamic forces on the rotor wings. The maximum forces were theoretically calculated and is 13.38 kN along the x-axis, -0.25 kN along the y-axis and then 0.5 kN along the z-axis.

Bioelectromagnetics for improved crop productivity : an introductory review with pilot study of pre-sowing treatment of tomato

Various electromagnetic (EM) treatments has been investigated for their potential in improving crop productivity over the past century. There is today an increasing amount of scientists advocating EM treatments as an organically compatible method for improving plant growth and yield. However, failure to produce repeatable effects and defining causal mechanisms has made it a study of much controversy and debate. The subject requires indepth interdisciplinary knowledge, making it inaccessible for the majority of biologists, horticulturists and growers. In this combined literature review and pilot study, these issues are addressed by providing a comprehensive introductory review of the topic plant bioelectromagnetics and its potential horticultural usability.

Query expansion med hjälp av en elektronisk tesaurus i en bibliografisk online-databas.

In this Masters thesis we investigate query expansion using an electronic thesaurus. We formed 30 topics from the library and information science field. For each topic three searches were made in the bibliographic database LISA Library and Information Science Abstracts via CSA Cambridge Scientific Abstracts. LISA has an electronic thesaurus attached. We used this thesaurus to form baseline queries, baseline queries expanded with synonyms, and baseline queries expanded with both synonyms and related terms.

Impact of hygiene training on dairy cows in northeast India : en hygientränings påverkan på mjölkkor i nordöstra Indien

Mastitis in dairy cows is an emerging and challenging disease in the tropics, including India. Nation-wide reports suggest that the incidence of clinical mastitis varies from 3.94% to 23.25%, and for subclinical mastitis from 15.78% to 81.60%. In Assam, a northeastern province of India, dairy is an essential part of the mixed farming system that exists in the state, but the milk yield is far below domestic standards. In 2009-2010, International Livestock Research Institute (ILRI) and local associates started to develop a training program for local farmers in Assam, in order to enhance the informal bovine dairy sector in and around Guwahati, India. The project continued until mid-2013.

Statusbedömning och förbättringsförslag för startkedjemaskineri, startkedja och linspel för stränggjutningsmaskin

The main goal with the master thesis has been to do a status evaluation of the chain machinery with its start chain and wire to secure the production on a short basis due to that a reconstruction is not planned at this time. An evaluation of the condition of the start chain and the rollers in the chain depository has been done. An offer has been requested for a new start chain and the evaluation of the start chains may be a basis for the decision taking. The production has been able to go on, although it has arisen some problems which have been difficult to find the causes for. There is no gathered ?picture? of the machinery status and a mapping of each machinery has been compiled of comprehensive logs.

Tick burden in neonatal roe deer (Capreolus capreolus): the role of age, weight, hind foot length, and vegetation and habitat on bed sites

This thesis deal with tick burden on roe deer (Capreolus capreolus) fawns, in relation to age, weight, hind foot length, and as well as to vegetation and habitat on bed sites. Roe deer fawns (N = 25) were captured from May 27 to June 27. Samples of ticks were collected and tick burden were estimated. Of all sampled ticks the nymphs and adults were Ixodes ricinus, while the larvae were not identified. 4.4 % of the sampled ticks were larvae, 55.0 % nymphs, 26.8 % adult females, and 13.8 % adult males.

Är företagets lönsamhet och finansiella ställning avgörande för beslut beträffande företagets expansion?

Even if the main purpose is to decide if the companies profitability and financial position is a determining factor for its growth, the purpose is to determine if there are any differences between big and small companies in there economical positions then they grow, in the selected industry. This thesis is mainly a quantitative study. The selected industry for the study is extraction of turf. The financial measurement that most clearly differ the growing companies from the not growing companies or the companies that didn?t change there amount of employees was the returns of the companies own capital.

Mångbruksplan Äspinge 2:2

This plan of multiple-use is made on the private owned forestproperty Äspinge 2:2 in the middle of Skåne. The term ?multiple-use? came to Sweden in the beginning of the twentieth century and has slowly grown until about 30 years ago when the laws of nature conservation and sustainability was written into the forest law. The so called ecoturism got more and more popular and people began to seek space and silence in difference to the life in the highly populated areas. This also encouraged foreign tourists to come to Sweden. Mostly danish, german, and dutch people.

Quantification of sleep in dairy cows in three different stages of lactation

The aim of this project was to quantify the total sleep time in modern dairy cows during24-hour periods and to investigate whether the total amount of sleep as well as timespent in different sleep stages varies between the dry period, early- and peak lactation.The distribution of sleep time between night and day was also examined. Furthermore,correlations between sleep and lying time, fluctuations in body temperature and heartbeat were included in the aim. Eight dairy cows of the Swedish Red breed were used inthis study, which was carried out between June and September 2010. In order toquantify sleep non-invasive electrophysiological recordings were performed.Simultaneously with collecting sleep data, body position and body temperature werealso recorded. No heart rate data was obtained due to difficulties of maintainingelectrodes for heart beat measurements attached to the skin.

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.

Prevalence of antibodies for Peste des petits des ruminants virus and Brucella and related risk factors in goat herds in urban and peri-urban agriculture in Kampala, Uganda

The world?s population reached more than 6.9 billion people in July 2011. It is expected that the population growth during the next 40 years will take place mostly in low-income countries and the population increase will be 2.3 billion people during 2011-2050. A rapid urbanization is also expected to result in 57.7 per cent of Africa?s population living in urban areas in 2050.

Centrumhandel i relation till externhandel : - en fallstudie om Strängnäs

In the 90's the establishment of external trade centers had a strong growth in Sweden, primarily in large and medium cities. Gradually took smaller towns by this development. In larger cities with larger and growing customer base than in small towns were not affected by the trade centers heavily, but in the smaller towns where the customer base was smaller, there was a risk that it created a negative competitive relationship between external trade center and trade in the citycenter. In some cases, competition is a positive development for both the citycenter and external trade areas, but in some cases there was a risk that the center became impoverished. In such situation there are theories that the different variety of different types of goods should be at the center and in external trade center could lead to a balanced trade relationship.
