For many years the benefits of using stockings that exert a pressure on the legs, to prevent and treat a number of health conditions, have been well known. For just as many years carers and caretakers have been struggling to put on these stockings onto the legs. The high compression strength of the stockings makes it very difficult to put them on the way one does with ordinary stockings. Today, me
Semantic roles, logical relations such as Agent or Instrument that hold between events and their participants and circumstances, need to be determined automatically by several types of applications in natural language processing. This process is referred to as semantic role labeling. This dissertation describes how to construct statistical models for semantic role labeling of English text, and how
In the post-genomic era, it has become evident that genetic changes alone are not sufficient to understand most disease processes including pancreatic cancer. Genome sequencing has revealed a complex set of genetic alterations in pancreatic cancer such as point mutations, chromosomal losses, gene amplifications and telomere shortening that drive cancerous growth through specific signaling pathways
Popular Abstract in Swedish Benskörhet (osteoporos) är ett tillstånd som definieras av låg benmassa och ökar med stigande ålder. Osteoporos är idag en av de stora folksjukdomarna och man räknar med att en tiondel av alla män och en fjärdedel av alla kvinnor i Sverige drabbas. Tillståndet är i sig symptomfritt men ökar risken att råka ut för ett benbrott (fraktur) redan vid lättare fall. Frakturer The aim of this thesis was to evaluate risk factors for bone fragility and fractures in postmenopausal women in a long-term perspective. The study period spanned from the age of 48 to age 82 and is thus unique in its length. The studied sample was homogeneous and consisted of 390 north European women from a population-based cohort. At the start of the study, general health and lifestyle parameters
Repair and reconstruction of major nerve trunks in the upper extremity is a very challenging surgical problem. Today, there is no surgical repair technique that can assure recovery of tactile discrimination in the hand of an adult patient following nerve repair. In contrast, young individuals usually attain a complete recovery of functional sensibility. The outcome from nerve repair depends mainly
In the modern business environment, there is growing number of companies placing weight on sustainability-related issues, such as waste management, local communities, use of resources etc. At the same time such stakeholders as investors, consumers, employees and communities are increasingly interested in understanding company’s efforts and progresses in the area of sustainability. With that respec
Depth data and bathymetry maps are used to analyze their association with tides, winds, currents and wave conditions in the port of Talara, at the coast of northern Peru. The objective is to investigate the processes that influence the sediment transport in the port. The sedimentation affects the saltwater pumps for fire fighting, obstructing them from delivering water since their operational wate
The reliability of energy supply is crucial for the well-being of individuals and the prosperityof countries. At the same time, energy production is closely connected to CO2 emissions,which is believed to have an important impact on human-induced global warming. In light ofresultant, partly counteracting challenges, energy efficiency has gained increasing attention as ameans of ensuring energy sup
Water pollution from industrial or household waste, containing dyes from the textile industry, poses a significant environmental challenge requiring immediate attention. In this study, we have developed a crosslinked-smart-polymer film based on 2-(dimethylamino)ethyl methacrylate copolymerized with other hydrophilic and hydrophobic commercial monomers, and its efficacy in removing 21 different tex

During the process of biomass gasification tars are formed which exit the gasifier in vapor phase. Tar condensation creates problems like fouling and plugging of after-treatment, conversion and end-use equipment. Gasification tars consist mainly of Polycyclic Aromatic Hydrocarbons (PAHs). Former research has shown the possibilities and difficulties of tar conversion by partial combustion. Basic st
The massive amount of genomic sequence data that is now available for analyzing evolutionary relationships among 31 placental mammals reduces the stochastic error in phylogenetic analyses to virtually zero. One would expect that this would make it possible to finally resolve controversial branches in the placental mammalian tree. We analyzed a 2,863,797 nucleotide-long alignment (3,364 genes) from
Popular Abstract in Swedish Förbränningsmotor är i dagens värld den mest använda kraftkällan för fordon. Förbränningsmotorn har kontinuerligt utvecklats och förbättrats sedan Nicolaus August Ottos och Rudolf Diesels dagar, och kommer att fortsätta att utvecklas långt in i framtiden. Ingen konkurrerande teknik har ännu på allvar utmanat förbränningsmotorns ställning. Det finns en lång rad tänkbara The prime mover in the world today is the Internal Combustion (IC) engine. The development and improvement of the internal combustion engines since Nicolaus August Otto and Rudolf Diesel has continued until today and will continue long into the future. No major competitor to the IC engine has yet emerged. There is a long list of potential competitors but they still have to prove their superiority
Popular Abstract in Swedish Avhandlingen består av två delar. Den första delen behandlar reglering av processer med lång dödtid. Avhandlingen ger förslag på hur regulatorer för dessa processer ska dimensioneras och jämför sedan prestanda hos dessa regulatorer med vanliga PID-regulatorer. Avhandlingens andra del handlar om metoder för automatisk övervakning av reglerkretsar i processindustrin. TvåThe thesis contains two parts, dead-time compensation and performance monitoring. The first part on dead-time compensation is about robust tuning procedures for dead-time compensating controllers (DTC). Both stable and integrating processes are considered. Simple experiments are performed to obtain process models as well as bounds on the allowable bandwidth for stability. The DTCs used have few pa
Lead time, defined as the duration between the moment a request was filed and the moment the decision was made, is an important aspect of decision making in market-driven requirements engineering. Minimizing lead time allows software companies to focus their resources on the most profitable functionality and enables them to remain competitive within the quickly changing software market. Achieving
The degradation of different polyethylenes-low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), and high-density polyethylene (HDPE)-with and without antioxidants and at different oxygen concentrations in the polymer granulates, have been studied in extrusion coating processing. The degradation was followed by online rheometry, size exclusion chromatography, surface oxidation
