Trafikverkets effektstyrningssystem - EFS 132 kV : Bidraget till minskade förluster
The technological legacy from the early electrification of the Swedish railroads has resulted in a power grid with a lower grid frequency than the national power grid from which it is fed. Energy transfer between these power grids with different frequencies requires substations, adapting the grid frequency for the rail road power grid. For this purpose, a feeding power grid has been built, stretching across the country from Boden in the north to Tälle/Häggvik in the south.Power transfer in the Swedish power grid results in voltage angle differences which increase with increasing loads and transfer distance. These voltage angle differences are transferred from the power feeding substations to the rail road power grid, will in some extent cause loss of energy due to unwanted power flows from north to south.To minimize the losses due to this phenomenon, a power management system called EFS 132 kV has been developed and implemented. The system minimizes the unwanted power flows and controls the desired power flow for a good distribution of loads between the power feeding substations.This thesis investigates the extent of the transmission losses avoided due to the EFS 132 kV that coordinates the idling angles to a common reference point.The results indicate that EFS 132 kV affects the power flow, especially between the northern substations through an improved load distribution.
The role of FGFs in the elicitation of different cellular responses
Fibroblast growth factors are signaling peptides that controls important cellular processes such as proliferation, differentiation, migration, adhesion and survival. Through binding to different types of receptors on the cell surface, these peptides can have different effect on the target cell. Which effect that is achieved depends on many factors. Thus, each of the 24 known FGFs different biological responses. The FGF receptors (FGFR 1-4) initiates different intracellular pathways which in turn leads to different biological responses.
Orsaker till kalvningssvårigheter och dödfödslar hos SLB och SRB
Difficult calvings and stillborn calves are costly for the producer and lowering these frequencies can decrease the costs for the dairy operation. Each calving in the herd is registered by the farmer and stored in a central database. The information is used to monitor the level of calving-difficulties and stillborn calves in the herd and nationally. Monitoring of these registrations is important to detect possible changes. Breeding-value prediction for calving traits is based on the calving information in the database.
Spelar språkresan roll? : Fyra individers upplevelser av språkresans betydelse för deras karriärval
The objective of the study is to examine whether the experience from language courses abroad has had any impact on the career choices for four individuals. Based on a qualitative research methodology, four semi-structured interviews have been executed. The two research questions have been answered by letting four people recount their experiences from language courses abroad linked to their self-images and career choices. The outcome is that the experiences from the language courses contributed to a more or less altered self-image. Most of all, the interpersonal abilities were fostered, which led to the formation of a self-image characterized by improved confidence in social settings.
Upplevelser och hanteringsstrategier hos ungdomar med IBD. : en litteraturstudie
The purpose of this study was to describe how adolescents aged 12-18 years with inflammatory bowel disease experience their illness and what coping strategies they use to manage their illness and improve their wellbeing. The method used was a descriptive literature study, and the result of the study included 15 scientific articles. Our results showed that IBD affected the adolescent?s everyday life and social life with friends, family and activities. The adolescents also reported that they experienced a feeling of vulnerability, altered body image and that they saw themselves as different from healthy subjects.
Betydelsen av personalens engagemang fo?r att arbeta med arbetsmiljo?arbete : -med utga?ngspunkt ifra?n fyra engagemangskapande faktorer
The purpose is to increase awareness of the importance of staff engagement in the work environment and how the organization works to engage employees to want to participate actively in the work environment.The questions we seek answers to in this study is the following:What affects the staff to engage in the work environment from a managementperspectiveAre there external factors that affect the organization and the individual's engagementto work with the working environment?We have create a model that is based on recent research to define our definition of engagement. The model contains four factors : Clarity, Advocacy opportunities, resources and feedback. The method we have used to answer the purpose in this study is ten qualitative interviews with persons with work environment responsibilities.The result shows that the engagement regarding work environment is important to get the employees to actively participate. To get the engagement from the employees the organizations need to provide, clarrity, advocacy opportunities, resources and give mutual feedback.
Spring ikapp omvärlden ? en studie om omvärldsbevakning i friskvårdsbranschen
The aim of this thesis is to investigate how small organisations within the subject field health and training work with their environmental scanning. The main questions in this thesis are: How do the organisations work with business intelligence/environmental scanning? What is their environment like and of which parts does it consist? How extensive is their work with business intelligence/ environmental scanning? Which are their main fields of application and how is the work compiled practically? In order to answer these questions we have chosen to use a qualitative method, which in our case consists of two interviews with people in managerial positions within the health and training subject field. The result of the two interviews is presented in a compilation, and it is thereafter discussed and analyzed. We used an existing theoretical model and altered it in order to correspond to the aim of this research..

Lönesättande samtal : samspelet mellan medarbetare och ledare
Bakgrunden till studien är mina egna tankar om hur de lönesättande samtalen inom arbetslivet egentligen fungerar nu när de har blivit alltmer vanliga på arbetsplatserna. Syftet med studien är dels att undersöka hur kommunikationen hanteras och upplevs under ett lönesättande samtal av medarbetare respektive ledare dels att utveckla kunskapen om vilken betydelse kommunikationens påverkan har för samspelet under det lönesättande samtalet. Studiens forskningsfråga har varit hur medarbetarna och ledarna upplever samspelet under samtalet, varför den sociokulturella teorin har använts tillsammans med andra kommunikativa begrepp och teorier. Studien har av den anledningen haft en fenomenologisk ansats för att få fram respondenternas subjektiva upplevelser av samspelet under det lönesättande samtalet. Som metod användes en öppen intervju med en frågeguide som innehåll ett antal olika teman som de olika respondenterna själva fick resonera kring.

Småhusproduktion : Utvecklingsmöjligheter hos JM AB
The Swedish building contractor JMRegion Öst would like to to investigatethe possibilities of developing andstreamlining the production of singlefamilyhouses. JM are producing singlefamilyhouses with prefabricated framesat a rate of about two houses per week.During construction, the different tasksare performed by JM?s own productionstaff but also by varioussubcontractors.When examining the schedules of recentlyproduced projects, it appears that allthe houses are more or less completedeight weeks before the customer moves into the house. During those eight weeksseveral operations are conducted such asinspections, installation of appliancesand cleaning procedures. The inspectionperiod constitutes between 25 and 35% ofthe complete construction period.By conducting interviews, it has beendiscovered that this final phase is anessential security buffer for delays anderrors that often occur.
Fotbollstränares pedagogik ? handlar det om lärande eller inlärning? : Ungdomstränares utsagor om arbetsmetoder och kommunikationsformer inom TipsElitverksamheten
Syftet med studien var att försöka kartlägga fotbollstränares pedagogiska grundsyn, huruvida det är lärande eller inlärning som bedrivs vid utbildning och utveckling av fotbollsspelare. Samhället och utbildningsväsendet har en utpräglad lärandefilosofi och har i mångt och mycket förkastat inlärningsbegreppet, dock upplevs det som om denna mentalitet fortfarande återfinns i idrottsrörelsen. Undersökningens metod bestod av kvalitativa intervjuer med tio TipsElittränare, där frågeställningarna utgick från begrepp som lärande, inlärning, kommunikation, instruktion och feedback. Mycket utav deras arbete grundar sig i Svenska Fotbollsförbundets utarbetade styrdokument, där lärandet i första hand beskrivs i termer av inlärning som ett resultat av instruktion. I tränarnas utsagor återfanns dock en antydan till andra perspektiv på lärande som utgick från tvåvägskommunikation samt en syn på spelaren som en självständig individ med eget ansvar för sitt lärande. Ytterligare forskning på hur lärande miljöer kan främja utbildning och utveckling på fotbollsplanen rekommenderas, dels för att kunna utveckla tränaren pedagogiskt men även för att kunna utveckla Svenska Fotbollsförbundets utbildningsmaterial.
Logopeder och barn i interaktion : Samtalsanalys vid behandling av språkstörning
Speech intervention for children with language impairment aims to both strengthen specific language skills and to reinforce the ability to participate in interactional contexts. Children with language impairment often have problems in interaction; therefore the contributions of the conversational partner are of great importance. Thus, the demands are high on the speech and language pathologist (SLP) for sense and cohesion in intervention. The aim of the present study was to examine how SLPs and children with language impairment interact in language intervention. An approach influenced by Conversation Analysis was used in order to identify various phenomena that occurred, and their effect on the structure of the interaction was analyzed.Four SLPs, two men and two women, were enrolled in the study. They participated in intervention with two children with language impairment each, i.e.
