Experimentell undersökning av provkroppar för trälimfogar
This thesis engages the topic of test methods for wood adhesives. Two test methods were evaluated, EN 302-1, a European standard, and ASTM D905, an American standard. The total amount of specimens manufactured and tested was more than 500. The adhesive bonds were tested in shear with an increasing load on the specimen until failure.The adhesives used were epoxy-resin, phenol-resorcinol-formaldehyde and a 2-K polyurethane. The test programme included five different types of intentional errors per method, in order to investigate the sensitivity of the test methods.
Förstärkning av betongkonstruktioner med kolfiber med avseende på olika brottstyper
The purpose of this report is to simplify the process of designing carbon fiber strengthening for existing concrete constructions, specifically beams. The intention has been to establish a flow chart containing information on the necessary testing and calculations for the design, to as far degree it is possible satisfy the requirements stipulated by Swedish and by extension, European authorities.To do this the report will examine a parking garage situated underground by Akademiska Sjukhuset, Uppsala. The parking garage was built in the mid-seventies, and has in recent years been subjected to a greater load than designed for by the construction of a road on top of it. FEM-Design has been used to obtain the internalforces of the beams and thereby determine whether they are in need of strengthening or not and thereafter design the strengthening according to Täljsten (2006) with some corrections from Täljsten (2011) due to new regulations.The result of this report is that the flow chart used is viable to design carbon fiber strengthening, atleast with the conditions met in our reference project.The conclusion drawn after working with this report is that there is a need for a clear standard for carbon fiber strengthening , preferably a standard that can be used throughout Europe..
Ombyggnad av lägenheter i ett 1950-tals flerbostadshus till kontorsbyggnad
The report aim to increase awareness of factors that have a major role whenremodelling an apartment building from the 1950s to offices.The thesis can be used for future projects when remodelling apartments to offices.The report can provide ideas and inspirations on how this can be done in aneffective way, ie . A way that does not require rebuilding the supporting structure,but only non bearing walls. The thesis also gives insight on the parts that will needto be supplemented from Boverket?s requirements in terms of accessibility,acoustic and fire requirements.The methods used in this thesis are literature studies, case study and sketch work.In the literature studies, the primary sources were Boverkets byggregler BBR, andArbetsmiljöverkets föreskrift AFS 2009:2 but other literature were also used. Theprimary items were chosen from the literature studies and they were furtheranalysed in the sketch work.
Ska det framtida Göteborg växa och gro?: En diskursanalys gällande beslutsfattares syn på urbant jordbruk
An increasing global population and a worldwide growing urbanization has raised the questionabout the future food security in cities all over the world. Peak-oil limits the access to cheap fossilfuels which threatens the global food-supply chain. This has resulted in a larger awareness anddiscussion related to urban agriculture. Growing crops and keeping animals within the city-borderscould be one way of creating a more robust and sustainable food supply for city dwellers. However,to enable an expansion of the urban agriculture many theorists argue that policies and institutionalstructures that supports and promotes city farming have to be developed.

Syftet med det här examensarbetet är att skapa och designa en användarvänlig Androidapplikation som trådlöst kan kommunicera med electronic control units i bil eller testmiljö.Androidapplikationen består av fem huvudskärmar, fyra vars uppgift är att skriva ut informationen som åker över CAN bussen. De fem skärmarna är start, felkoder, sensorer, ECU extract och overview. Start tar dig vidare till de andra skärmarna, felkoder skriver ut alla felkoder, sensorer skriver ut alla sensorvärden, ECU extract skriver ut all information och overview visar en virtuell instrumentbräda. Användarutvärderingar har utförts för att ta fram både designen och layouten på applikationen.
Hisskärna av skalväggar i höga byggnader : Ett alternativ till den platsgjutna kärnan
A common way to stabilize high rise buildings is to use an elevator core built of concrete. Today, we use to build these elevator cores of in-situ concrete. Precast concrete twin wall (double wall) is a semi-finished product that has become more common in recent years. This diploma work studies how the twin wall works out as structural elements in an elevator core. The work also shows some possible ways of designing twin walls and highlights some important parts of the design that will be vital to the stability of the building. The result shows that it is important to think through where the element joints should be placed.
RESEBYRÅERS KONKURRENSFÖRDEL UTIFRÅN SEXHÖRNINGEN : Fritidsresor och Ving, vilken resebyrå väljer kunden utefter positioneringen i sexhörningen?
Resebyråerna växer i allt stadigare takt, allt eftersom fler människor väljer att färdas med flyg på grund av den effektiva globaliseringen som pågår världen om. Ving och Fritidsresor är två resebyråer som följt med utvecklingen sedan mitten av 1900-talet och har nu blivit två av de ledande resebyråerna i Sverige.Därmed är det intressant att göra en jämförelse mellan dessa och se om det finns några påtagliga likheter eller skillnader. Detta arbete kommer att beröra Ving och Fritidsresors konkurrens för- och nackdelar ur ett kundperspektiv. Det har tagits fram med hjälp av konkurrensmedelsmixen, sexhörningen som består av följande sex hörn, geografi, sortiment, kommunikation, människor, service och pris. För att ta reda på hur betydelsefulla hörnen är för kunden och hur de upplever att Ving och Fritidsresor möter deras behov.Undersökningen har gjorts med hjälp av en kombinerad enkätundersökning av kvantitativ- och kvalitativa frågor som senare har jämförts med aktuell teori.
Mikrosimulering för analys av Mästergatans förlängning i Enköping
Two of the main approach roads into the city of Enköping are Salavägen and Stockholmsvägen. They are connected to each other through the street Bangårdsgatan in the roundabout Salatullen and crossing Fannakorset, respectively. These crossings are from time to time heavily loaded, which is why the municipality plan for a new street in parallel to Bangårdsgatan. The traffic will then be spread out and is thereby reducing the density. The new street is actually an extension of the existing Mästergatan, a side street to Salavägen, to the east and connecting it to Stockholmsvägen or a street nearby.The purpose of this Master thesis is to show how the new street can be drawn in order to discharge the traffic in the area between the roundabout Salatullen and the crossing Fannakorset.
Sjuksköterskans arbete med Manchestertriage : arbetstillfredsställelse och kompetens
Background: Triage is the sorting of patients according to the severity of medical assessment. Triage has a long history of use in Anglo-Saxon countries but is a fairly new method in Sweden. Researchers have described the Manchester triage group method (MTS) and a literature review of the concept; working contentment and competence focusing on triage. Aim: The ambition with this study was to describe a number of triage nurses working conditions. The research questions were; working with MTS- does it bring work contentment? What kind of competence is needed? Method: Data was collected from 74 triage nurses by a questionnaire containing 37 questions and two questions provided the nurses the opportunities to describe their triage experiences.
Anhörigvårdares Upplevelser Av Sitt Vardagliga Arbete
The family and relatives caring of older people in Sweden lies on an old tradition. By legislation the responsibility for the older people has gone through a development from the family to the society. According to the new social service law (2000) it is not that clear that the utmost responsibility lies on the society. According to the social service law ( 5th chapter, 10 §) the municipality should ease things up by giving support and relief for relatives taking care of older people, prolonged ill and function disabled people. The purpose with the study was to examine how the family care givers are finding their everyday work and their experience of the support that the society is giving.

A township that departed had no experience.
Konstruktion av provladdare till singelmolekyldetektor
This report describes the development of a sample loader for my diploma work at Q-linea AB in Uppsala. The sample loader will replace the process of loading fluid samples into Q-linea?s instrument for biomolecule analysis. The earlier process was done by hand and was a time consuming and inefficient task.The work was initiated with a design phase where an overview of the system was created. The sample loader will be receiving text commands from a PC that coordinates all the subsystems like pumps and lasers on the analysis instrument.
Markavvattningsföretagens geografi och konsekvenser i Trosaåns avrinningsområde
Agricultural drainage is widely used to manage the amount of water in the ground in order to improve conditions for cultivation. However the effects of drainage companies on water regimes are considerable leading to runoff changes such as altered stream flows, peak flows and water levels. In a greater extent this could imply an increased risk for floods along affected watercourses. This study analyzes the extension of agricultural drainage within the drainage basin of Trosaån in Sweden by ArcGIS mapping. In a statistical analysis, historical variation in streamflow in relation to mean precipitation and mean temperature are investigated for the study area.
Tillförlitlighet hos trafikolycksklassificering
Today?s wind power plants are only compensated for their reactive power consumption at no-load. As the wind power plants grow bigger the amount of reactive power they need also increases. This is no longer a problem that can be ignored, especially as the net owners are beginning to charge the reactive power they transport.In this thesis a couple of different methods of compensation and their prices will be discussed and evaluated. Problems, such as self-excitation, that can occur if one fully compensates the wind power plant will also be brought to surface.
