Utvärdering av Raman- och IR-spektroskopi, differentiell svepkalorimetri och dielektrisk spektroskopi för materialstudier på choklad

On a request from the water sewage plant Gryaab in Gothenburg a power quality survey wasperformed. The voltages and currents have continuously been sampled in the incoming 10 kVsubstation HSP01 from April-August 2008. Power quality measurements were also performedin Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of theinduction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps tothe plant. The reason for the latter measurement was due to registered negative transients eachtime the motor was connected to the grid. The cause of the transients could be explained by thecoupling in the substation, the ageing of the motor which could result in damage of thebearings or resonance in the motor circuit which amplifies high frequency harmonics.

Viktminskning, "Quick-fix" eller ett livslångt upprätthållande? : En kvalitativ intervjustudie om påverkande faktorer vid varaktig beteendeförändring

SammanfattningSyfte och frågeställningarSyftet med studien är att undersöka vilka faktorer som tidigare viktminskningskunder på Itrim upplever vara avgörande för att lyckas med en varaktig beteendeförändring inom kost och motion. Syftet besvarades utefter följande frågeställningar:Vilka personliga faktorer upplevs vara avgörande vid en varaktig beteendeförändring?Vilka sociala faktorer upplevs vara avgörande vid en varaktig beteendeförändring?Vilka miljömässiga faktorer upplevs vara avgörande vid en varaktig beteendeförändring?MetodValet att göra en kvalitativ intervjustudie grundar sig på att det är deltagarnas subjektiva upplevelser som anses relevanta för att besvara studiens syfte och frågeställningar. Då deras upplevelser granskas utifrån Social Cognitive Theory har studien en deduktiv ansats. Sju kvinnor intervjuades och alla är fortfarande kunder hos Itrim, som motionskunder.

In my analysis I interviewed twelve pupils from upper-secondary school who had 20 % or more truancy during their three years of studying in upper-secondary school and achieved a result to these pupils had problems with absenteeism then primary school. The pupils agreed about the school?s existence but they need schools of practical type.

Kvalitetsprocesser och mätning av pinnfräsar : ? Empirisk studie av produktionsmätutrustning vid frästillverkning

This master thesis investigates quality procedures and measuring of solid carbide end mills, with the main focus on measuring equipment. The thesis has been written in collaboration with a special production department for solid carbide end mills at Sandvik Coromant in Gimo. The department?s needs and constraints have been the foundation of the project and the main research question is: how to measure end mills in order to ensure good quality of the produced end mills. The project has contained both a theoretical study consisting of a literature review and practical studies in the workshop with the objective to identify an end mill?s main parameters and the relationship between an end mill?s geometry and the manufacturing processes.

bildning, utbildning och litteratur

Syftet med denna undersökning är att reda ut den syn på retorik som ligger bakom återinförandet av retorik i svenskämnet på gymnasiet. I och med gymnasiereformen Gy 2011 har nya kursplaner i svenska implementerats. Bland nyheterna finns bl.a. en fordran att eleverna skall lära sig den retoriska arbetsprocessen och använda den för att framföra intressanta och övertygande skriftliga och muntliga framställningar som tar hänsyn till syfte, mottagare och kommunikationssituation. Dessutom ska de elever som läser Svenska 3 kunna använda den retoriska arbetsprocessen som ett redskap för analys.

Project EQS - Elektronisk växelreglering för motorcykel

Husaberg Scandinavia AB is a company producing and developing a range of motorcycles for both on- and off-road use. Husaberg provided the project group with a task of developing an entirely new way of operating the sequential transmission that can be found in today?s motorcycles. The target was to bring the product from idea to a functional prototype ready for further tests. Operation of the motorcycles transmission is today made by a foot pedal placed on the left hand side of the bike.

Utvecklingen av dödsfall till följd av oavsiktlig skada i länder under snabb ekonomisk utveckling

Purpose.The purpose of this essay was formulated as to examine the relationship between the development of deaths caused by unintentional injury and fast economic development in a country. The purpose is to create a picture of the development in the chosen countries.Background.Injuries and the deaths that sometimes follow are a problem for all communities, if nothing else just because of costs and the absence of incomes for the state. Countries ability to restrain these deaths should be of interest. Studies show that the number of deaths causedby unintentional injuries correlates inversely with the GDP/c, we can therefore expect that better economic conditions leads to fewer deaths and vice versa. It has been shown that an economic crisis often leads to considerably higher death rates.

Jämförelsestudie för tre olika metoder att beräkna genomstansning i betong : Skillnader i genomstansningskapacitet för metoderna i BBK04, EK2 och BHB

Before the European construction standards were introduced in January 2011, it was mainly themethod in BBK04 that was used for calculating punching capacity in concrete structures, and in lesscommon cases the method in BHB. The method of BBK04 is easy to use and have had the samestructure since the first was published in 1979. The Concrete handbook method (BHB) where usuallyonly used when a higher punching capacity was needed and the cross-sectional height where fixed,calculations using this method entails more work, but will in return usually give a higher capacity. Italso allows the use of shear reinforcement to increase the cross-section capacity. The method ofcalculating punching shear in EC2 differs largely from the methods of BBK04 and BHB.

Simulering av översvämningar i Nedre Dalälven

Mosquitoes are found in extremely large numbers in the lower parts of the River Dalälven. In the year 2000 the mosquito nuisance was especially high, resulting in foundation of the Biological mosquito control project. Since 2001 mosquito larvae are controlled by using a biological pesticide BTI (Bacillus thuringiensis ssp israelensis). The mosquito fauna in the area is dominated by flood water mosquitoes, a group of mosquitoes that are very aggressive and form new generations of mosquitoes during every single flooding event during the summer. To be able to efficiently control the mosquitoes it is essential to know the extension and locality of the flooding.

Hur påverkas dvärghamstrar av att vistas i hamsterbollar?

Lately the popularity to keep different species of dwarf hamsters has increased in Sweden. The requirements of the Swedish legislation to keep hamsters as pets are low which could be a reason for the increasing popularity. Hamsters are in nature generally nocturnal and can travel far distances to find food sources during their active part of the day. Their eyesight is poor, but is compensated by their well-developed hearing and olfaction. ?Run about balls? are made of plastic and the hamster is placed inside it where after the ball is placed on the floor and the hamster can then run protected outside the cage.

M?nniskoriket Tage Lindboms modernitetskritik i efterkrigstidens Sverige

During the period after the Second World War Sweden underwent a quick transformation due to a strong economic development. Decades-long rule for the Social Democratic Party now led to the creation, in Sweden, of a modern welfare state. This period in Swedish history is often considered to be the time when ?the Swedish model? was formed. Tage Lindbom (1909?2001) was a historian and intellectual in the Swedish labor movement.

Kommunikation i operationsmiljö : en litteraturöversikt

AbstractAim: The aim of this study was to investigate if treatment with ?dry needling? in myofascial triggerpoints (MTrPs) in the rotatorcuff muscles may affect impingement symptoms such as pain during provocative tests, shoulder mobility, and function. The research questions were: Does the value of pain change on the Visual Analog Pain Scale (VAS) between before and after treatment? Do the positive provocative tests for impingement change between before and after treatment? Does the active shoulder mobility change between before and after treatment? Does the self-rated function change between before and after treatment?Method: The study was a prospective randomized intervention study and 19 persons with impingement symptoms (mean ± standard deviation; 58 ± 18 years, and shoulder pain duration 3.9 ± 1.6 months) were randomized into two groups. The groups were tested before, directly after and 3 weeks after treatment.
