Time resolved absorption spectroscopy has been used to study photoinduced electron injection and charge recombination in Zn-porphyrin sensitized nanostructured TiO(2) electrodes. The electron transfer dynamics is correlated to the performance of dye sensitized solar cells based on the same electrodes. We find that the dye/semiconductor binding can be described with a heterogeneous geometry where t
Background: Irritable bowel syndrome (IBS) and gastrointestinal (GI) dysmotility disorders have a similar clinical picture, although dysmotility disorders require the attention of a specialist. Patients with primary Sjogren's syndrome (pSS) have also been described to suffer from IBS-like symptoms. No objective marker is available to distinguish between the patients. A visual analogue scale has be
BACKGROUND-Multiple laboratory tests are used in the diagnosis and management of patients with diabetes mellitus. The quality of the scientific evidence supporting the use of these assays varies substantially. APPROACH-An expert committee compiled evidence-based recommendations for the use of laboratory analysis in patients with diabetes. A new system was developed to grade the overall quality of
Background: Total hip joint replacement (THR) is a high volume, effective intervention for hip osteoarthritis (OA). However, indications and determinants of outcome remain unclear. The 'EUROHIP consortium' has undertaken a cohort study to investigate these questions. This paper describes the variations in disease severity in this cohort and the relationships between clinical and radiographic sever
Background and purpose Treatment of displaced femoral neck fractures in Sweden has shifted towards more arthroplasties, especially hemiarthroplasties. We describe the hemiarthroplasty population in Sweden 2005 through 2009. Methods Since 2005, the Swedish Hip Arthroplasty Register has registered hemiarthroplasties on a national basis. We assessed hemiarthroplasty procedures in the Register 2005-20
Although for large area detectors it is crucial to find an alternative to detect thermal neutrons because of the He-3 shortage, this is not the case for small area detectors. Neutron scattering science is still growing its instruments' power and the neutron flux a detector must tolerate is increasing. For small area detectors the main effort is to expand the detectors' performances. At Institut La
Mapping coastal inlets and their catchment areas is essential for management of the coastal zone. The coastal inlets are important channels of exchange of nutrients, water and sediment between the land and sea. They are also important elements of the coastal hydrological system and play a vital role in controlling the water flow into the sea during floods. Blocking of the coastal inlets is one of
In this study, the production of enantiomerically pure (1R,4S,6S)-6-hydroxy-bicyclo[2.2.2]octane-2-one ((-)-2) through stereoselective bioreduction was used as a model reaction for the comparison of engineered Saccharomyces cerevisiae and engineered Escherichia coli as biocatalysts. For both microorganisms, over-expression of the gene encoding the NADPH-dependent aldo-keto reductase YPR1 resulted
Background: We recently reported (Curr Biol 22:683-688, 2012) that the eyes of giant and colossal squid can grow to three times the diameter of the eyes of any other animal, including large fishes and whales. As an explanation to this extreme absolute eye size, we developed a theory for visual performance in aquatic habitats, leading to the conclusion that the huge eyes of giant and colossal squid
Acute management of traumatic brain injury (TBI), in particular mild TBI, focuses on the detection of the 5-7 % who may be harboring potentially life-threatening intracranial hemorrhage (IH) using CT scanning. Guidelines intending to reduce unnecessary head CT scans using available clinical variables to detect those at high IH risk have shown varying results. Recently, the Scandinavian Neurotrauma
Study objectives: A method for medication reconciliation that reduces medication errors and healthcare contacts when a patient is discharged from hospital, LIMM-DI (Lund integrated medicines management-discharge information) had been previously developed by the authors. LIMM-DI is structured information written for the patient and sent to the next caregiver. In this study, the use (implementation
Exposure to some pesticides and persistent organic pollutants (POPs) has been indicated to be a risk factor for non-Hodgkin's lymphoma (NHL). Epstein-Barr virus (EBV) has been associated with some subgroups of NHL. In a previous study we found an interaction between high concentrations of some POPs and titres of antibodies to EBV early antigen (EA IgG) in relation to NHL. In the present study we m
Purpose. The aim was to examine if the retinal circulation in the pig can be accessed using interventional neuroradiology and to explore the possibility to create occlusions that result in experimental retinal ischemia. Methods. Six experiments were performed using 100 kg pigs. The external carotid system was catheterizised using fluoroscopy monitored, transfemoral, endovascular approach. Transien
Background: The expected reduction in cervical cancer incidence as a result of increased access to antiretroviral therapy is yet to be seen. In this study we investigated the effect of HIV infection and treatment on high-risk (hr) human papilloma virus (HPV) prevalence and distribution. Methods: Cervical cells from 515 (220 HIV positive and 295 HIV negative) women, recruited during community cervi
Mountains provide a variety of ecosystem services, such as drinking water, which sustains not only mountain communities but also people living further downstream. While climate change threatens most ecosystems, its negative impacts are up to three times greater in high altitudes. As well as changing the water cycle this further accelerates climate change. Although they contribute comparably little
Saccharomyces cerevisiae is a commonly used industrial organism which cannot consume xylose naturally. This is a problem since xylose is a major component in renewable resources, for instance lignocellulose. The Weimberg pathway is a pathway that converts xylose into α-ketoglutarate. It has been successfully integrated into S. cerevisiae, enabling it to utilize xylose. The successful strain had th
Jämfört med många andra industrier så har byggnadsindustrin halkat efter med att implementera digitala lösningar. I dagsläget är det enbart ett fåtal materialleverantörer och tillverkare som erbjuder en tjänst av så kallade digitala BIM-objekt till sina produkter. Dessa digitala produkt kopior kan nyttjas för flera syften i projektmodeller vilket exempelvis gynnar desing-team och entreprenörer. DeThe construction industry has in general been rather slow in its implementation of new digital solutions compared to other industries. To date, only a handful of material suppliers are offering a service of so-called digital BIM-objects of their products. These 'digital product copies' can be utilized in projects' BIM-models for several purposes, being favorable to the design team and
Japan currently faces a rapid increase in labor immigrants due to the decrease of the population. The number of immigrant children is expected to increase because of the open labor immigration policy. Although the education of immigrant children is very complex, Hamamatsu city and Kani city have implemented successful educational policies to solve the problems of out-of-school children. This resea
Across the world, there is a call to combat the climate crisis and tackle growing socio-economic inequalities. The Danish Citizens’ Assembly on Climate (CAC) is a case of attempted deliberative democracy seeking pathways to this outcome. This thesis asks how the CAC might catalyse a Danish sustainability transition. With democratic discourse theory and the concept of just sustainability, I conduct
Statistical comparison of single cases to small samples is a methodology that has been extensively used in, for example, cognitive and clinical neuropsychology. This is most often done to determine changes in cognitive processing after an individual has incurred some type of brain damage. In a clinical setting one often wish to infer whether a patient exhibit abnormally low performance on some cog
