Popular Abstract in Swedish Abstract Hydrogen embrittlement is a degradation process of mechanical/tribological properties (toughness, wear etc.) of mating steel surfaces. This is caused by the presence and interaction of hydrogen with applied stresses. Therefore, it is important to quantify the hydrogen content which could be dissolved under applied stresses in steel.

This is caused by the presence and interaction of hydrogen with applied stresses. Therefore, it is important to quantify the hydrogen content which could be dissolved under applied stresses in steel. Water contamination of lubricants is often considered as

Numerous geometric problems in computer vision in- volve the solution of systems of polynomial equations. This is true for problems with minimal information, but also for finding stationary points for overdetermined problems. The state-of-the-art is based on the use of numerical linear algebra on the large but sparse co- efficient matrix that represents the expanded original equation set. In this

When low calorific value gases are fired, the performance and stability of gas turbines may deteriorate due to a large amount of inert ballast and changes in working fluid properties. Since it is rather rare to have custom-built gas turbines for low Lower Heating Value (LHV) operation, the engine will be forced to operate outside its design envelope. This, in turn, poses limitations to usable fuel

The ability to predict surface defects in outer panels is of vital importance in the automotive industry, especially for brands in the premium car segment. Today, measures to prevent these defects cannot be taken until a test part has been manufactured, which requires a great deal of time and expense. The decision as to whether a certain surface is of acceptable quality or not is based on subjecti

Objective: The purpose of the study was to compare in prospective randomized fashion a manually sutured esophagogastric anastomosis in the neck and a stapled in the chest after esophageal resection and gastric tube reconstruction. Summary Background Data: Despite the fact that all reconstructions after esophagectomy will result in a cervical or a thoracic anastomosis, controversy still exists as t

Popular Abstract in Swedish Hjälpsystem i tunga fordon (bussar)As more and more focus is put on the environmental questions and the request for cleaner transportation the demand on the vehicles increases. Especially the environmental request of the public transportation that is visible to the public and operates in the centre of the city. The demand on the buses used for public transportation will increase. The whole bus must be optimised, usually only the pr

A feed control strategy, based on estimated sugar concentrations, was developed with the purpose of avoiding severe inhibition of the yeast Saccharomyces cerevisiae during fermentation of spruce hydrolyzate. The sum of the fermentable hexose sugars, glucose and mannose, was estimated from on-line measurements of carbon dioxide evolution rate and biomass concentration by use of a simple stoichiomet

Object. With increasing use of endovascular procedures, the number of aneurysms treated surgically will decline. in this study the authors review complications related to the surgical treatment of aneurysms and address the issue of maintaining quality standards on a national level. Methods. A prospective, nonselected amalgamation of every aneurysm case treated in five of six neurosurgical centers

Popular Abstract in Swedish Jätteplaneterna, Jupiter, Saturnus, Uranus och Neptunus, är de största planeterna i solsystemet. De ligger långt från solen och har alla betydande gasatmosfärer, upp emot hundra gånger mer massiva än hela jorden. Tack vare de tjocka gashöljena, med en sammansättning som liknar solens, kan man förstå att jätteplaneterna bildades i en gasskiva. Denna skiva kallas för solGiant planets form embedded in a protoplanetary disc around a young star. Close to the midplane a large fraction of the available mass in solids is found in particles of cm to dm in size, which drift towards the star due to friction with the surrounding gas. In paper I, II, III we describe a novel theory that explains how embryos, planetesimals larger than ~1000 km, grow efficiently by sweeping up

This paper provides the first regional econometric decomposition of CO2 emissions from fuel combustion in eight regions of the world. Using the best publically-available time series data (1971–2011), the analysis examines the key determinants and relationships of the ‘Green Energy Economy’ (GEE) in Africa, Asia, Latin America and the Caribbean, the Middle East, Non-OECD Europe and countries from t

Uppsatsens syfte är att med utgångspunkt i NJA 2017 s. 1195 undersöka vilken verkan köparens passivitet får beträffande rätten att åberopa fel, när säljaren har handlat grovt vårdslöst eller i strid mot tro och heder. I NJA 2017 s. 1195 formulerade Högsta domstolen en på allmänna principer, och då främst på principer om lojalitetsöverväganden, grundad passivitetsregel. Den föreskriver att om säljaThe purpose of this thesis is to investigate the effect of the buyer’s non-performance, in terms of the right to claim defects, when the seller has acted with gross negligence or in violation of faith and honour. In NJA 2017 s. 1195 the Supreme Court formulated a non-performance-rule based on general principles, especially on principles of loyalty. It prescribes that if the seller has acted with g

This thesis is oriented around designing the world first inelastic hyperspectral LiDAR(Light Detection and Ranging) system for aquatic use. The system was designed around the task of monitoring zooplankton and environmental indicators in water. Scheimpflug lidar was previously developed for monitoring flying insects, aerosols and gases. Here we extend the concept to inelastic hyperspectral ranging ca

I denna uppsats utreds och analyseras hur rättsväsendet hanterar hatbrott begångna på internet. År 2013 rapporterade Brottsförebyggande rådet att personuppklarningen vad gäller hatbrott begångna på internet är mycket låg. Följaktligen fortsätter uppsatsen med att identifiera orsakerna till den låga personuppklarningen samt de brister rättsväsendet besitter på området. I avslutande del av uppsatsenThis paper is set out to investigate and analyze how the judicial system handles hate crime committed on the internet. In 2013 the Swedish national council of crime prevention (Brå) reported that the clearance rate in terms of hate crime committed on the internet is very low. Hence the paper continues with identifying the causes of the low clearance rate and the shortcomings the judicial system po

Popular Abstract in English The two most used building materials in harbor structures are undoubtedly steel and concrete. These two materials are often combined in the structures of wharfs and quays where most steel sheet pile walls have cap beams of reinforced concrete. The degradation processes of these structures must be taken into account both when designing new structures and when inspecting The two most used building materials in harbor structures are undoubtedly steel and concrete. These two materials are often combined in the structures of wharfs and quays where the steel sheet pile walls often have cap beams of reinforced concrete. The degradation processes of these structures must be taken into account both when designing new structures and when inspecting existing harbor structu

Background and purpose Adequate depth of cement penetration and cement mantle thickness is important for the durability of cemented cups. A flanged cup, as opposed to unflanged, has been suggested to give a more uniform cement mantle and superior cement pressurization, thus improving the depth of cement penetration. This hypothesis was tested experimentally. Materials and methods The same cup desi

This thesis analyses the spatio-temporal patterns of inequality and income growth in Sweden during the time-period 1990–2016. It aims at answering the question of whether there has been increasing inequalities, if so where and why. The study is motivated by the ongoing debate on regional development in research, public policy and media which frequently raise questions on the ongoing patterns of in
