Flexible Beams in Dymola

Mechanical systems can be modeled by connecting rigid bodies with loads and other components. Prescribed motions and initial values can be defined in a system. The behaviour of the rigid bodies can then be studied and their motions can be computed. If a body is elastic the motion of some defined points are not identical to a rigid body when loads are affected. To model a mechanical system the dyna

Vibration Analysis of Underground Tunnel at High-Tech Facility

Max-lab is a national laboratory operated jointly by the Swedish Research Council and Lund University. Nowadays, the Max project consist of three facilities (three storage rings): MAX I, MAX II, MAX III and one electron pre-accelerator called Max Injector. A new storage ring is needed due to improved nanotechnology. MAX IV is planned to be the next generation Swedish synchrotron radiation facilit

Träs tryckfasthet vinkelrätt fiberriktningen

At present there are no concrete guidelines how to calculate the pressure resistance capacity of the timber at the load perpendicular to grain. The test options ASTM, CEN and ICO gives three different results in testing of an equal body. With this knowledge the value for the characteristic compressive strength capacity of the pressure perpendicular to the grain will be reduced to 2.7 MPa. The reduc

Design of Equipment for Characterization of Elastomers Using Impact Testing

Ett viktigt moment vid tillverkning av kartongmaterial till livsmedels-förpackningar är laminatorn. I laminatorn täcks råpappersmaterialet av smält polymer i det så kallade nypet. Nypet i sin tur består av en stor kylvals och en mindre gummiklädd nypvals. Genom att styra kraften som verkar på nypvalsen kan kontakttrycket i nypet regleras. Vinkelhastigheten med vilken nypvalsen roterar är stor och

Design of Foundations for Wind Turbines

The Swedish government has specified a goal for the Swedish wind power that in 2020 it will generate 30 TWh of energy per year. This should be compared with the present energy produced from wind power of 2.5 TWh / year. To meet these goals, several thousand new wind turbines have to be built. Today, we build the most land-based wind turbines on strong and stiff soils, but probably in the future

Arkitektur och konstruktion i vertikal stad

En teoretisk vertikal stad konstrueras i ett samarbete mellan en student från Arkitektprogrammet och en student från Väg och vattenprogrammet. Den vertikala stadens vision är att skona naturen från horisontellt växande städer genom att bygga uppe i luften och endast ha ett litet fotavtryck på marken som påverkar naturen minimalt. Den vertikala staden vill genom att bygga en kompakt stad där samhäl

Vibation Reduction by Shaping the Terrain Topography

MAX-lab is a synchrotron radiation laboratory run in cooperation between Lund University and the Swedish Research Council. It currently consists of three stor-age rings, however, construction has begun of the fourth. MAX IV will be located outside of the Lund University Faculty of Engineering campus, in the northeastern part of Lund. Induced by the development in material technology at the nanomet

Traffic Induced Vibrations at Road-Bridge - Experimental and Numerical Analysis

In the north-east part of Lund, Sweden, the MAX IV facility is (in the event of writing this thesis) under construction. MAX IV is a synchrotron radiation facility which has a high requirement regarding low vibrations. Within this thesis a nearby road-bridge for the highway E22 was studied using experimental and numerical methods. The aim was to determine the magnitude of the road-bridge influence

Structural Response With Regard to Explosions

When a structure is subjected to an explosion, it will have a response that differs from the one that arises from a static load. Engineers are used to design for static loads but the common knowledge of how to design for explosions is weak. There are guidelines for how to design for explosions with simplified methods but they are partly outdated and the explanation of how they are derived is vague

Användarnas egenuttryckta behov och talboksverksamhetens framtid : den svenska talboksverksamheten ur ett användar- och empowermentperspektiv

The aim of this master’s thesis is to examine how the Swedish model for production and distribution of talking books to the print disabled can be designed in the future, on the basis of the self-expressed needs of the users. Three questions were formulated in order to achieve this aim: 1. What needs do the users, according to themselves, have in relation to talking books to achieve equal means of

In my study I have used a qualitative approach in the form of four semi-structured interviews with social consultants. Social Con-sultants working in th

Att bli vuxen med en sällsynt diagnos - En kvalitativ studie om övergången från barn- till vuxenvård

Sällsynta diagnoser är en bred grupp diagnoser som, trots att de var för sig är mycket ovanliga, tillsammans drabbar ett stort antal personer. På senare tid har framsteg inom forskningen lett till att medellivslängden ökat för många av dessa diagnoser och allt fler patienter uppnår vuxen ålder. Detta har skapat en ny patientgrupp som vuxensjukvården har svårt att ta hand om. Många utredningar har Background: Rare diseases, a diverse group of conditions which each represent few patients, are a challenge for the Swedish health care system. Despite efforts by the European Union and Swedish institutions to address these patients’ needs, there is still a lack of scientific studies and political initiatives when it comes to adult patients living with these diagnoses. Many patient organizations h

OCEAN ACIDIFICATION

Ocean acidification is a consequence of the anthropogenic release of carbon dioxide (CO2) to the atmosphere. When CO2 is dissolved in water it affects the composition of ions and lowers the pH of the water. As the partial CO2 pressure in the atmosphere increases a new balance is reached with the surface waters which causes the pH of the surface oceans to decrease. For small shallow seas this effec

H&M - Det ansvarsfulla företaget?

Of interest is to understand how H&M acts to legitimize their goals, choices and requirements of its operations by examining the company's policy and reporting. In this way, an image provided of which responsibilities a multinational company must take, and what obligations

Polens abortlagstiftning: en intersektionell studie av den legalt (o)tillgängliga aborten i Polen

This paper is about the legal access of abortion for women in Poland. The 1993 ban on abortion has resulted in a nearly total elimination of the abortion services contributed to women within the public health care system. Furthermore, the availablity of contraceptives is limited. Doctors unwilling to help and a stigmatisation of abortion has created a dangerous environment for those who cannot aff

Screening MHC alleles of Great Reed Warblers (Acrocephalus arundinaceus) from hatching to breeding using 454-sequencing technique

Abstract The Major histocompatibility complex (MHC) plays a central role in the vertebrate immune system. The protein products of MHC genes present foreign peptides to T-cells, which then initiates the appropriate immune responses. MHC genes show extreme level of polymorphism and this was suggested to be maintained by selective pressures exerted by various parasites. Although associations between

Kravet på ställföreträdare för barn i anknytningsmål - Om barnet i migrationsprocessen och beviskrav för ställföreträdarskap

Familjeåterförening är en viktig princip inom både svensk och internationell rätt. I svensk rätt regleras denna princip i utlänningslagen där en möjlighet till uppehållstillstånd på grund av anknytning ges. Vissa bevisrättsliga frågor måste dock uppfyllas för att uppehållstillstånd ska kunna ges. I denna framställning behandlas bevisning angående ställföreträdarskap för barn som söker uppehållstilFamily reunification is an important principle in both Swedish and international law. In Swedish law this principle is coded into the Aliens Act making it possible to get residence permit on the grounds of ties to Sweden. In order to get a residency permit there are a couple of things you have to prove, for example your identity and the existence of a relation to a person in Sweden. If you are und
