Uppbyggnad och reglering av en pumpstation till ett injektionssystem
I was assigned to the thesis as part of a project GMA AB (Ground Machinery Applications AB) is running. The project aims to develop a new method for injection of drilled holes in rock walls. Currently, the injections usually involve cement but the basic idea of the project is to replace cement with a supplement called Silica sol.Silica sol is known as a gelling liquid. The gel time is controlled by a mixing of saline. Depending on the amount saline that gets mixed in, the gel time varies.
Omvårdnad av häst i boxvila : ett examensarbete baserat på en enkät gjord bland hästägare i Sverige
This thesis is focused on what impact stall confinement has on a horse?s mental and physical welfare. It was of great interest to get a gathered picture of how Swedish horseowners had experienced having their horses in stall confinement. A survey study was conducted to achieve this.
The survey included twelve questions which for example investigated the horses? age at the time of stall confinement, the length of stall confinement and their sexes.
Emotionella sprickor och utbrott - i en sorg
Intangible feelings of sorrow and grief, caused by events like separation, death, loss and trauma, all leave some kind of traces in us and they play an important role in our development. The individualistic society here in Sweden has shaped us to keep our feelings inside and at bay; since our childhood we have learnt that showing emotions like tears, sorrow and sadness are signs of weakness and can make others and yourself feel uncomfortable. With the starting point from my own experience and understanding of how we can deal and handle grief, I take a closer look on how jewelry, objects and rituals can be of importance in a grieving process and our lack of visual outer display of grief in today?s society. Through Sara Ahmeds theory I found a new possible way of understanding emotions and how they shape us.
Framgångsfaktorer och hinder med Lean produktion i Kina
AbstractLean production has become one common concept within industries to make the work more effective and to meet today?s hard competition. A challenge for Chinese production is the threat from new low cost countries. It will become very difficult to succeed to produce to a lower cost than these countries; this led to that Chinese companies must develop new strategies, according to Lee and Zhou (2000). This will put China in front of new challenges and new strategies can be needed to retain their strong competitive advantages.
Förändringar i bankers verksamheter efter uppkomsten av internetbanker
Då tekniken med rask takt gått framåt de senaste åren har de flesta företag dragit nytta av dess fördelar. Flertalet stora framsteg har gjorts på denna front och många organisationstyper har gjort stora implementeringar av nya IT-system i syfte att uppnå konkurrenskraft på marknaden. En väldigt betydande sådan är internetbankens införande i bankvärlden. Detta är något de allra flesta banker idag erbjuder sina kunder. Denna införande har säkerligen haft en inverkan på både kunders syn på banken och även hur banker arbetar för att kunna anpassa sig till teknologiutvecklingen.
Gröna lösningar - en fallstudie av aktuell teknik för energieffektivitet för Skanska Sverige ab
ur society is today in a phase of development in environmental and sustainable thinking. Alarming reports show changes in climate caused by our load and exhaust of resources. The energy usage contributes to a big part of it, by its emission of carbon dioxide. The built environment uses around 40 % of the total energy consumption in Sweden and requests to strongly reduce it are presented from both EU and national level.This thesis brings up the subject of green building with a focus on how we can create more energy efficient buildings in projects of new construction. Since the construction industry today often fails to pass on the knowledge between different projects, as a return of experiences, the construction company Skanska suggested the topic for this thesis.
Barn- och ungdomars uppfattning om sin övervikt och fetma som ett problem samt skillnader i aktivitetsnivån hos barn- och ungdomar beroende på deras sociala familjesituation
BackgroundIncreased prevalence of obesity in children- and young adults and risk for diseases related to obesity will increase the burden on medical care. It is important to identify early risk factors that can be noticed by nurses in the daily work.AimThe aim was to investigate whether children- and young adults themselves perceive overweight as a problem and if there was a difference in the measured activity levels between overweight children- and young adults in families with different socio-economic family status.Method descriptionExisting survey from the Obesity Centre at the Akademiska Sjukhuset were examined together with the results from an accelerometer, where children- and young adults activity was recorded, compared to their perception of how active they were. The results were compared using a statistical software program and compiled with descriptive and non-parametric statistics.ResultsThe results do suggest that the majority of children- and young adults experiencing excessive weight have a problem in their everyday lives. Nearly half overestimate themselves as more active than what the actual measurements with accelerometer demonstrated. Much time is spent in front of the TV and computers.

Systemets uppgift är att samla upp och transportera bort den bergskross (muck) som genereras vid själva borringreppet.
Kilhus i plast : Omläggning av stålprodukt till produkt i plast
AbstractOur bachelor degree thesis was carried out in collaboration with Ivar Petterssons Järnmanufaktur AB in Smålandsstenar. We were asked to replace their wedge housing, used to fasten the wires to the power lines, with a similar structure in a plastic material. The idea for this project started with Ivar Petterssons Järnmanufaktur AB having problems with the casting quality that forced them to perform expensive tests on each of the wedge houses to ensure the quality. They are currently produced in China which is also a major drawback because it requires expensive long delivery times.The method we used is Fredy Olsson's Princip- and Primärkonstuktion (1995). We have consistently been in the project on so-called "broad front", which means that you create several sketches, ideas and changes in parallel, and then evaluates all.
Tillval och anpassning : kundens valmöjligheter vid köp av nyproducerad bostadsrätt
Background: The real estate market has previously been subsidized by the government. The construction has been characterized by standardization and large scale complex. In the current situation there are other conditions on the real estate market, subsidies do not occur at the same degree and the market is more competitive. Customer influence has also changed. Today the customers want to customize their apartment by personal needs and lifestyle.
Användning av högpresterande betong i husbyggnader : Materialförsök och modellering
Idag är intresset för högpresterande betong (HPB) växande runt om världen då fördelarna är många, eftersom slankare, tätare, starkare och lättare konstruktioner kan tillverkas. Detta examensarbete handlar om materialförsök och modellering för en typ av HPB som ska användas i husbyggnation. Arbetet inleddes med materialförsök i färskt tillstånd, där god gjutbarhet och konsistens eftersträvades. Utgångspunkten var från ett grundrecept med två olika ballastsorter (slaggballast med flygaska och krossballast från asfaltindustrin med silikastoft), vilka namngavs till pilotförsök 1 och pilotförsök 2. Vidare valdes pilotförsök 1 att provas i hårdnat tillstånd då det visades att det var mer ekonomiskt lönsam eftersom ballasten inte behövde siktas, lägre vct tillhandhölls och att flygaskan som användes i pilotförsök 1 är billigare än silikastoft som användes i pilotförsök 2. Resultaten efter 28 dygn för de materialförsök som utfördes i hårdnat tillstånd var:Tryckhållfasthet; 141,9 MPaDraghållfasthet; 7,0 MPaBöjdraghållfasthet; 10,0 MPaElasticitetsmodul; 46,4 GPaKrympning efter 56 dygn; 0,5 ?Samtliga försök utfördes enligt svenska standarder (SS). Dessutom vidareutvecklas och förbättrades ett redan arkitektoniskt gestaltat Attefallshus ur ett konstruktions- och hållbarhets perspektiv, där fokus låg på transport- och produktionsförutsättningar.

Att organisera beståndet eller ?Äntligen hittar man!? : om hylluppställning och exponering på Arkenbiblioteket
The aim of this master?s thesis is to examine how libraries can organize their collections in terms of library shelving and displays and to what extent these activities stem from a desire to create a user-friendly library. The thesis is based upon a case study of Arkenbiblioteket in Sweden and the material consists of a literature study and qualitative, semi-structured interviews with three librarians at Arkenbiblioteket. The theoretical framework consists of theories on information-seeking behavior, classification and displays. These theories form the basis of the analysis of the empirical material.The main reason for the changes in shelf arrangement at Arkenbiblioteket was a desire among the library staff to create a user-friendly library.
Fallstudie av produktionschefers ledarskap
The thesis presented in this report has been made on behalf of Scania and their basic frame design department with the subject to solve an implementation of a weight sensing system in the chassis. The system is supposed to be implemented in the seat springs, and the reason for this is that all the force will have to go through the weight sensing transducers. With all the force going through the transducers the weight sensing system will not be sensitive for the differences in tolerances from manufacturing. The transducers could be pre-calibrated to avoid a calibration of the whole vehicle after it?s completed from the manufacturing line.Weight sensing systems is today a reality in trucks with air springs.
Betyg och bedömning : i en förberedelseklass år 9
Grades and assessment are a natural part in the school's everyday existence, deliberations about equivalent assessment is discussed all the time between teachers, students, home and school. They that in front are influenced of a grade or a judgement are in first hand the students and therefore are the important for the students to know which objectives and grade criteria that apply for them to achieve at the end of years 9. The aim with this survey is to get the knowledge about how a tutor grade family?s student in a preparatory class in stopped of years 9, in Swedish as a second language. Do the students in a preparatory class's get grades or a judgement? This is interesting also in order to know to which grade criteria students in a preparatory class have to achieve in the compulsory education?s later years and to know how a tutor assesses these students on the basis of those objectives and criteria that apply.
