Some of the main bottlenecks for the development and commercialization of photovoltaic/thermal hybrids are the lack of an internationally recognized standard testing procedure as well as a method to compare different hybrids with each other and with conventional alternatives. A complete methodology to characterize, simulate and evaluate concentrating photovoltaic/thermal hybrids has been proposed

Ankylosing Spondylitis (AS) is a chronic inflammatory disease with onset in young adults, but little is known about the prevalence in older age groups. Furthermore, there is very limited information of health status of elderly patients with AS. Our objective was to estimate the prevalence of moderate to severe radiographic sacroiliitis in elderly men and its impact on health.

Haemophilia B is caused by a heterogeneous spectrum of mutations. Mutation characterization is important in genetic counselling, prenatal diagnosis and to predict risk of inhibitor development.

Simian virus 40 (SV40), a polyoma virus of the rhesus macaque was discovered in 1960 as a contaminant of human polio vaccines produced in monkey cells. A number of studies have reported the detection of SV40 nucleotide sequences in human tumors, mainly mesotheliomas, but the reports have not been consistent. The presence of SV40 in 26 consecutive cases of malignant mesothelioma of biphasic type wa

Both total ankle replacement (TAR) and ankle arthrodesis do show some problems in long-term studies. To choose either of these surgical options is a delicate task. There are no randomized studies reported in the literature and no previous studies in which patients constitute the own controls.

To estimate incremental costs for patients with psoriasis/psoriatic arthritis (PsO/PsA) compared to population-based referents free from PsO/PsA and estimate costs attributable specifically to PsO/PsA.

Background. The accuracy of ultrasound in the diagnosis of congenital malformations has been the subject of many studies. Most of these are hospital-based studies over a limited period of years presenting high detection rates and also relatively high incidence of major malformations. We present here a large population-based study over a long period of years. Methods. The prenatal diagnoses are com

Obesity may be associated with increased risk of prostate cancer (PCa). According to one hypothesis, obesity could lower the risk of non-aggressive tumours, while simultaneously increasing the risk of aggressive cancer. Furthermore, central adiposity may be independently associated with PCa risk; it is also associated with diabetes, which itself may influence risk of PCa. We studied the associatio

One of several quality indicators that are relevant to study is patient's satisfaction with health care in the ambulance services. Regular measurements of patient satisfaction in this field have not been carried out previously and a validated method of measurement is lacking.
