Atypical femoral fractures are insufficiency fractures in the lateral femoral diaphysis or subtrochanteric region that mainly affect older patients on bisphosphonate therapy. Delayed healing is often seen in patients with incomplete fractures (cracks), and histology of bone biopsies shows mainly necrotic material inside the crack. We hypothesized that the magnitude of the strains produced in the s
There are many studies portraying iron (Fe) and nitrogen (N)-functionalzed carbon as an electrocatalyst along with possible elucidation of catalytically active sites. Despite continuous controversial debate on the active sites/species, the presence of N is believed to be undeniably needed for the efficient catalysis, whereas the necessity and role of Fe are still debated. To clearly understand the
The extreme soil conditions in metalliferous mine soils have a negative influence on soil biological activity. Therefore, amendments are often used to improve soil quality and activate microbial communities. In order to elucidate some of the factors controlling microbial growth and community structure after application of amendments in acid mine soils, we performed an incubation experiment with fo
A scanning photoelectron microscope, utilizing a focused beam of monochromatized photons in the energy range from 15 to 150 eV, has been used to study the thermal desorption of oxide layers on Si(100). The instrument can provide high-resolution photoelectron spectra from selected parts of the surface as well as images showing the lateral distribution (on a micrometer scale) of elements in differen
This paper addresses the challenge of how to understand and handle divergent views on the need for leadership interventions between managers and subordinates. Recent popular discourses of leadership, such as the authentic leadership perspective, privileges the potential leader himself or herself as the origin of leadership. This perspective thereby neglects the view of the followers and the essent
Summary The egress strategy in high-rise buildings has traditionally been based on the sole use of stairs for evacuation. However, it is becoming more common to include evacuation elevators in the egress strategy in high-rise buildings. Traditionally, evacuation elevators have not been allowed as an evacuation route, and people have been instructed to not use elevators in case of fire. This means
Interest has grown in using the requirement of total joint replacement (TJR) as a "hard" outcome measure. Limitations exist, however, in the use of such an outcome, in particular the variability in the decision to perform surgery, length of surgical waiting lists, and sensitivity to change. This special interest group is exploring ways of retaining the clinical relevance of TJR but overcoming the
Objective: contribute to the existing body of knowledge about the specific needs of first-time parents specifically for early parenthood. Method: the databases PubMed, MEDLINE, PSYCINFO, CINAHL, EMBASE, Family Studies Abstracts, and Web of Science, were searched using search terms: prenatal, antenatal, preparation, education, parents, parenthood. The meta-synthesis included 12 articles representin
This article quantifies the energy saving potential and robustness of nine energy retrofitting measures, as well as four combinations of these, for residential building stocks of three major cities in Sweden and for five scenarios of future climatic conditions, downscaled by a regional climate model (RCM). The retrofitting measures are evaluated for five temporal resolutions of hourly, daily, mont
Introduction: Persistent hypertension is a key risk factor for coronary heart disease, stroke and other cardiovascular diseases, such as heart failure. For primary care physicians, hypertension is the number one diagnosis for office visits and for our communities, the treatment of high blood pressure (BP) and its consequences constitutes a substantial economic burden. Aim: To evaluate yoga as a tr
Registers of quality can be used to ensure that health care recommendations are followed, to verify the logistics of care and serve as a basis for research when population based data are needed. Validation of quality is important and is the fundament of accurate interpretation of collected data. In the present validation of sentinel node biopsy (SN) for malignant melanoma in Southern Sweden during
Increasing trends of natural organic matter (NOM) in surface water in Nordic countries may cause future problems for drinking water producers. Emerging membrane technology, such as ultrafiltration (UF) and nanofiltration (NF), has the potential to produce safe drinking water of good quality from sources with high organic concentrations. In the present pilot study, surface water from three sources
The performance of single-channel temporal noise reduction methods generally deteriorate in high noise environments, whereas spatial beamformers can maintain some level of speech enhancement. This paper presents a solution where a low complexity single-channel noise reduction method is integrated into the feedback control loop of an adaptive blind beamformer with the purpose of robust blind speech
Existing criteria recommended by ACC/ESC for identifying patients with ST-elevation myocardial infarction (STEMI) from the 12-lead ECG perform with high specificity (SP), but low sensitivity (SE). In our previous study, we found that the SE of acute ischemia detection can be markedly improved without any loss of SP by calculating, from the 12-lead ECG, ST elevation in 3 vessel-specific leads (VSLs
Over the years we have seen an increased interest in businesses and in research for how to create conditions for entrepreneurship in established businesses (referring to corporate entrepreneurship). From research we know that access to and use of resources is critical for realizing corporate entrepreneurship activities. Even though the role of resources has been examined this conceptual paper iden
