LYCCA is a detector system consisting of different types of detectors which can be used flexibly to meet the individual requirements of different experiments focused on studying exotic nuclei far off the line of stability. It was developed for the HISPEC/DESPEC programme which is part of the NUSTAR collaboration at the future Facility for Antiproton and Ion Research (FAIR) in Darmstadt, Germany. T
This report incorporates a product styling development concept carried out on Scania a vehicle manufacturer known for its premium long haulage trucks, located in Södertälje, Sweden. The report consists of the development of the writers’ conception and implementation of the term “Driver Focus” on Scanias truck interior. The project is carried out using various different industrial design techniques
Tetra Pak is a large scale organization that provides its customers with a food packaging solution based on laminated carton board in various package formats. The packaging material is produced in more than 50 converting factories represented world wide. The production develops the material in roll form that are loadable in the filling machines. Each roll arrives to the filling site with a barcode
A rising problem within electronics today is that, since the frequencies have increased dramatically, it is now very difficult to measure signals. If a traditional probe is used, then the direct contact will destroy the signal. The general idea behind this master thesis project is to make use of the crosstalk between transmission lines to create non contact test points. This thesis aims to evaluat
Today, vehicles are equipped with advanced electronics and complex alarm systems but still vehicle and cargo theft is a huge problem around the world. After struggling with this issue for several decades, the government in Brazil finally had enough and voted that all new vehicles manufactured or imported to the country are required to be equipped with an electronic device enabling tracking and imm
Denna uppsats behandlar normer och värderingar kring kvinnlig och manlig ära utifrån rättsliggjorda ärekränkningsbrott i Stockholm mellan åren 1474 och 1481. En kvantitativ metod i kombination med en hermeneutisk metod har använts för att komma fram till om ärekränkningarna tycks ha varit ett manligt eller kvinnligt fenomen under perioden. Resultatet visar en överrepresentation av män både när det
Abstract: The human gastro intestinal tract (GIT) plays a significant role in the well-being and has a significant impact on human health. Probiotics are the live microbial food supplement which alters the microbial composition in gut and prebiotics are the substrates that enhance the growth of probiotics. Our interest was to examine the prebiotic utilization of this probiotics and to check the c
Abstract The significance of terrestrially derived iron (Fe) for marine ecosystems and its implications on other biogeochemical cycles is well recognised. It has been recently highlighted that the concentration of Fe in several Swedish rivers has increased strongly over the last 40 years. Four rivers draining into the Baltic Sea were used in the present study in order to assess the aggregation pr
In this thesis, a novel method for characterizing Permanent Magnet Synchronous Machines(PMSMs) based in the dynamic response of the analyzed motor is evaluated. The most significant motor characteristics -torque, flux and efficiency maps- are computed from the motor voltage, currents and rotor position data sampled during the experiment. This way of obtaining the characteristics of the motor is po
Effekter av träning i fastande tillstånd Den tydligaste effekten av uthållighetsträning är förbättrad kondition. Ordet kondition kan definieras som samspelet mellan lungor, hjärta, blod och muskler. Lungorna ska växla syrgas från inandningsluften och släppa ut koldioxid. Hjärtat ska pumpa blod till lungorna och ut i kroppen. Blodets uppgift är att syresätta musklerna vid fysisk ansträngning. Allt
ABSTRACT The objective of this project was to study if the adaptive background affects the spectral sensitivity of budgerigars (Melopsittacus undulatus) tested in bright light. Two budgerigars were trained, by associative learning with food rewards, in dual choice tests to discriminate monochromatic light stimuli of nine different wavelengths from an adaptive background with ultraviolet light (UV
This project is a study that has described what condition based maintenance is and has examined the possibilities with condition based maintenance on the new A26 submarine. It finishes with a detailed case study of how a condition based maintenance system could look like on the submarine’s diesel engines. Questions that have been answered are; what is condition based maintenance and how does it wo
Abstract Ketoprofen, naproxen, diclofenac, and ibuprofen are four widelyused anti-inflammatory drugsthat areproduced in several kilotons each year.They end up in natural water recipients which couldvary inpH from around 6.0 to 9.0. Bearing in mind that most of thesepharmaceuticals are weak acids and therefore dissociates in different degree depending on surroundingpH and the chemical’s pKa, we ca
Ett nytt protein som hjälper Haemophilus bakterien att fastna i luftvägarna På ytan av luftvägsbakterien Haemophilus influenzae, finns en rad proteiner. Genom att flytta dessa proteiner till en annan bakterie, Escherichia coli, har vi visat att de kan binda till ett protein som finns i våra luftvägar. Bindningen till luftvägarna är ett första steg i etableringen av en infektion som sedan gör oss
PEJL PÅ RASTANDE FLYTTFÅGLAR Varje vår och höst passeras Falsterbo av miljontals flyttfåglar. Många mellanlandar här för att fylla på sina bränsledepåer och vila upp sig inför nästa etapp på resan. Frågor som är intressanta inom flyttfågelforskningen är bland annat hur länge fåglarna rastar och om längden på vistelsen är kopplad till art, ålder, kön, fettreserver eller flyttningsstrategi (i det hABSTRACT The aim of this study was to examine autumnal stopover strategies of migratory passerines, with the main focus on stopover duration, departure time and departure direction in relation to biometrics (age, sex and fat reserves), different migratory strategies (long, short-to-medium and partial migration) and weather conditions. During the autumn migration season of 2010, in conjunction wi
In the E. ON sponsored research project, Distibution LABoratory, at the Department of Industrial Electrical Engineering and Automation at LTH the impact of the increased move towards use of cables in the Swedish distribution grid is examined. The project also built a model of a small distribution grid. The model was used to simulate a Petersen coil earthed grid system. Petersen coil earthing lower
Solar storms are a phenomenon that has a wide array of adverse consequences on technological systems, power systems in particular. During severe solar storms a geomagnetically induced current (GIC) starts to flow through long conducting structures, such as power lines and pipelines. The probability of solar storms has a roughly linear relation with the sunspot activity level which varies in 11 yea
Upptäcka gener inblandade i diabetes I många sjukdomar, så som diabetes, spelar människans gener en viktig roll i vem som insjuknar och hur utvecklingen sker. Därför är det viktigt att, i den mån det går, identifiera dessa gener så vid insjuknande, ge varje patient en mer specialiserad vård som kan bromsa sjukdomsförloppet. Diabetes är en metabolisk sjukdom där kroppen inte kan reglera glukoshaAbstract Aims/hypothesis Diabetes, a metabolic disease rapidly increasing worldwide, is triggered by both genetic and environmental factors. Longitudinal studies, such as the Malmö Prospective Project (MPP), give a unique opportunity to study life-long risk of developing a disease. In MPP, more than 2,000 individuals developed diabetes during a mean 25-year follow-up time. However, patients with
The objective of this master thesis is to review the present and future condition of generator step up power transformers at the combined heat and power plant Öresundsverket, in Malmö. The objective of this work was to prolong the lifetime of power transformers at Öresundsverket. The thermal properties of power transformer are been taking into consideration for their life time assessment. The most
