By precipitating a complex salt Ly(OS)(8) of the positively charged protein lysozyme and the anionic surfactant octyl sulfate OS-, one can generate a true ternary system: water-Ly(OS)(8)-NaOS. Using NMR diffusometry and U spectroscopy measurements the thermodynamic parameters of the association processes have been determined. The solubility product of the complex salt, K-s, is 10-(28) M-9.(1) On
76 patients were examined clinically and radiologically 27 to 36 years after a fracture of the distal radius. The average age was 31 years at the time of injury and 63 years at follow-up. In 81% of the patients there was no difference between the fractured and the non-fractured side. No patient had to change his or her occupation or leisure activities because of the fracture. There were more degen
In this document, a large number of mathematical models describing various physical, biological and chemical processes in a wastewater treatment plant are presented. In most cases, the models are fairly simple as they are inteded for steady-state simulations based on yearly averages of the influent wastewater charteristics. The combination of models forms a software tool namned URWARE (URban WAter
It has been stated many times that the formation of radiation infringements in PbWO4 is to a big extent stipulated by the non-stoichiometry defects of the crystals, arising in the process of their growth and annealing. To refine the idea of characteristics of the non-stoichiometry defects and their effect on the radiation hardness of PbWO4, the current study is aimed at the melt composition infrin
The effects of varying extracellular concentrations of K+ and Ca2+ [K+]o and [Ca2+]o on force development and membrane potential were investigated in the guinea-pig mesotubarium. At [K+]o up to 40 mM, spontaneous action potentials were present, while higher [K+]o gave sustained contractures at a stable membrane potential (-24 to -12 mV for [K+]o from 60 to 120 mM). Tension decreased successively w
The aim was to investigate the influence of age and gender on quality of life (QoL), complaints, and the presence and nature of self-reported diseases in persons aged 75 and older with cancer (n = 150), compared to a matched group without cancer (n = 138). A second aim was to investigate factors associated with poor QoL in people aged 75 and older. QoL was measured with Short Form (SF-12) and Euro
Popular Abstract in Swedish The last period of life among older people has been very little explored, even though it is well known that for the majority of the population death will occur in old age, both in Sweden and in other western countries. The intention in Swedish society is to provide high quality end of-life care for everyone (SOU 2001:6), not just to those receiving care in a hospital orThe aim of this thesis was to investigate old people's care and quality of life during the last period of life, but also to investigate their own and next-of-kin's experience of this phase. The thesis is based on four studies using separate samples. The sample (n=1198) in study I was drawn from the care and services part of the sub-study ?Good Aging in Skåne? (GAS). The criteria for inclusion in s
Fuel cells are electrochemical devices that directly transform chemical energy into electricity, which are promising for future energy systems, since they are energy efficient and, when hydrogen is used as fuel, there are no direct emissions of greenhouse gases. The cell performance depends strongly on the material characteristics, the operating conditions and the chemical reactions that occur ins
Both timber and glass are materials that have aesthetically pleasing properties. An appealing idea is to combine them to overcome the drawbacks and utilise the beneficial mechanical properties. Adhesive bonding with an appropriate adhesive could provide a uniform stress distribution at the transition between the materials.
This report presents a study of three different adhesives, silicon
In this paper, four major parameters of fresh water production from saline sources are discussed. The parameters are desalination technology type, water sources input type, energy sources and productions cost per cubic meter. Five different types of desalination technology are presented and bench-marked for long-term use. RO and MSF are dominant technologies. Six different input water sources are
Popular Abstract in Swedish Reumatoid artrit/ledgångsreumatism (RA) är en kronisk inflammatorisk sjukdom som i första hand drabbar lederna. Man uppskattar sjukdomens förekomst i den vuxna befolkningen till cirka en halv procent och den är 2-4 gånger vanligare hos kvinnor. Vi vet inte vad som orsakar RA, men såväl ärftliga som omgivningsfaktorer har betydelse. RA har ett varierande förlopp. Dels kaRheumatoid arthritis (RA) is characterized by persistent inflammation, progressive joint damage and disability. This thesis describes the outcome after 10 years in a cohort of 183 RA patients (116 women, 67 men) recruited 1985-89. The mean age was 51 years and symptom duration 11 months at inclusion. Standardized clinical, biochemical and radiographic assessments were performed annually. Health st
Recording of medical procedures makes it possible for medical staff to review their work, learn from the mistakes and produce material for education. Medical videos tend to be long, which has an impact on usability and raises issues concerning memory storage. The aim of this master thesis is to make the material more user-friendly with an intelligent toolbox based on machine learning and image an
The use of Reinforcement Learning (RL) to design controllers for safety critical systems is an important research area. On the one hand, RL can function in and adapt to complex and changing environments without requiring a model of the system. On the other hand, in such systems robustness is of high importance, as well as ways to guarantee and certify a level of robustness. This project investigat
During the last decades the spread of the invasive species round goby, Neogobius melanostomus, has largely increased in the Baltic Sea affecting the ecosystem, biodiversity and species interactions. Round goby originates from the Caspian Sea and has most likely been introduced multiplied times via ships ballast water to different areas of the Baltic Sea. The establishment has had both negative and
Supercritical fluid extraction method was optimized and applied to extract seed oil from baobab seed (Adansonia digitata L.). A full-factorial design was used to investigate the interaction influence of density and temperature in the range of 0.6-0.8 g/ml 40 to 77 °C, respectively, on the extracted amount of oil from crushed seeds. The results showed that density has a significant influence on the
This thesis seeks to examine the suitability and robustness of transfer learning models in creating an efficient reCAPTCHA v2 classifier, and further evaluates their performance against various adversarial attacks. Three models - DenseNet201, EfficientNetV2, and InceptionV3 - were trained and assessed, highlighting the applicability of transfer learning techniques in the classification of reCAPTCH
