UV/TiO2/H2O2, UV/TiO2 and UV/H2O2 were compared as pre-treatment processes for the detoxification of mixtures of 4-chlorophenol (4CP), 2,4-dichlorophenol (DCP), 2,4,6-trichlorophenol (TCP) and pentachlorophenol (PCP) prior to their biological treatment. When each chlorophenol was initially supplied at 50mg l(-1),UV/TiO2/H2O2 treatment supported the highest pollutant removal, COD removal, and dechl
The aim of the present study was to examine mean HbA1c and blood pressure levels during a 5 year period in 442 type 1 adult diabetic patients in relation to the incidence and progression of retinopathy, nephropathy and to cardiovascular morbidity and mortality. The study showed, that in patients under routine care at a diabetic unit with four visits to the out-patient clinic per year, the intraind
Epistemic uncertainty has been suggested to be fundamental to human experience. The authors of this paper believe that people need to exercise creativity in their conjectures, drawing upon knowledge and experience, in order to generate solutions to both instrumental and epistemic problems, and encourage higher orders of learning. Innovative methodologies are needed which can provide support for in
Popular Abstract in Swedish Ljusspridning och absorption i biologisk vävnad - modeller och mätningar Visionerna är stora i medicingruppen på avdelningen för atomfysik, LTH, nämligen att utveckla nya metoder för förfinad diagnostik och selektiv behandling av cancer, hjärt- och kärlsjukdomar med hjälp av laserljus. Möjligheten till att med ljus detektera och karakterisera sjuk vävnad, exempelvis tIn this work a number of theoretical models, describing light propagation in matter, have been applied to and developed for the examination of tissue. The aim was to model the light scattering and absorption in tissue in order to improve the understanding of underlying mechanisms of laser-based diagnostics and treatment modalities utilised for cancer and cardiovascular diseases. The models studied
Video-on-Demand (VoD) and video sharing services account for a large percentage of the total downstream Internet traffic. In order to provide a better understanding of the load on these services, we analyze and model a workload trace from a VoD service provided by a major Swedish TV broadcaster. The trace contains over half a million requests generated by more than 20000 unique users. Among other
The paper addresses the theoretical concept and methodological usefulness of 'lay theories' for conducting comparative research. 'Lay knowledge' is a well-researched concept particularly in medicine and health (e.g. Williams & Popay 2006), even if often regarded as an 'obstacle' that needs to be overcome in order to spread 'proper' scientific, medical knowledge. Critical studies within medicin
The current research focuses in understanding how inlet pressure, EGR, combustion phasing, engine speed and pilot main ratio are affecting the main parameters of the combustion (e.g. efficiency, NOx, soot, maximum pressure rise rate) in the novel concept of injecting high octane number fuels in partially premixed combustion. The influence of the above mentioned parameters was studied by performing
Governance of common resources such as water calls for rethinking structure, legal frameworks and property rights. In order to promote the decentralization of water governance, Water User Associations (WUAs) were created in many countries, such as India and Turkey, to operate and maintain irrigation systems as well as take over the responsibility of water distribution among water users. Despite pr
The rapid expansion of the university sector has channelled many students into study programs that lead to employment in new kinds of jobs, occupations and professional groups. There are three main reasons why more and more occupations get their training within the university system (a) The qualification and competence level of the labour force has been raised, due to changes in the economy an
This presentation discusses an ongoing research project that aims to collect data about the practice of information search. It seeks to learn more about different ways in which tourist information is collected at different stages of a journey. Speaking to tourism planners and reading tourism research, it seems as if the digitalization of information has completely changed tourists’ information sea
Background: Parkinson's disease (PD) is a chronic progressive neurodegenerative disease that results in functional loss and disability. People with PD have an increased risk of falling, and most of their falls occur while walking. As yet, there is limited knowledge concerning activity avoidance due to perceived risk of falling in people with PD. In order to quantitatively assess perceived walking
Congenital muscular dystrophy with laminin α2 chain-deficiency (MDC1A) is one of the most severe forms of muscular disease and is characterized by severe muscle weakness and delayed motor milestones. The genetic basis of MDC1A is well-known, yet the secondary mechanisms ultimately leading to muscle degeneration and subsequent connective tissue infiltration are not fully understood. In order to obt
Although border politics have been given much theoretical attention in recent years, empirical studies of identity construction among border police officers are less common. In 2014, a two-year collaborative project partly funded by the EU was initiated in order to increase international collaboration between border police officers in the Baltic Sea area. The participating organizations were borde
Proteiner är fascinerande makromolekyler som är fundamentala för alla levandeorganismer. De utgör byggstenar i våra celler, ansvarar för transport och signalering både inom och mellan våra celler, utgör en del av vårt immunförsvar och katalyserar bildningen av andra molekyler. Proteiner består av flexibla kedjor uppbyggda av olika aminosyror. Varje aminosyra har olika egenskaper och den specifika Proteins are complex macromolecules that are fundamental to all living species. The stability of proteins are governed by non-covalent forces within the protein and between the protein and its surrounding environment. At high concentrations proteins are susceptible to self-association, which may lead to amyloid fibril formation – a process linked to many diseases, such as Alzheimer’s disease, Park
For many polar organic micropollutants, biotransformation by activated sludge microorganisms is a major removal process during wastewater treatment. However, our current understanding of how wastewater treatment operations influence microbial communities and their micropollutant biotransformation potential is limited, leaving major parts of observed variability in biotransformation rates across tr
Although conventional computer technology made a huge leap forward in the past decade, a vast number of computational problems remain inaccessible due to their inherently complex nature. One solution to deal with this computational complexity is to highly parallelize computations and to explore new technologies beyond semiconductor computers. Here, we report on initial results leading to a device
Peripheral nerve injuries are difficult to treat, and the clinical outcome after surgical repair and reconstruction is still insufficient, particularly concerning recovery of sensory function. To improve the clinical treatment strategies, experimental models are used to systematically examine the mechanisms behind nerve regeneration and assess the improvement of nerve regeneration by introduction
Although the literature on the Maillard reaction in infant formulas is extensive, most studies have focused on model systems, and in only a few cases on real food systems. Therefore, the objective of the present study was to determine the status of the Maillard reaction, both the early and advanced phases, in a variety of commercial infant formulas available on the Swedish market. Ten powder and l
Laser-wakefield accelerators (LWFAs) are high acceleration-gradient plasma-based particle accelerators capable of producing ultra-relativistic electron beams. Within the strong focusing fields of the wakefield, accelerated electrons undergo betatron oscillations, emitting a bright pulse of X-rays with a micrometer-scale source size that may be used for imaging applications. Non-destructive X-ray p
BACKGROUND: Neurological disorders are increasingly recognised as major causes of death and disability worldwide. The aim of this analysis from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2016 is to provide the most comprehensive and up-to-date estimates of the global, regional, and national burden from neurological disorders.METHODS: We estimated prevalence, incidence, d
