Background: Malignant melanoma and non-melanoma skin cancers are among the fastest increasing malignancies in many countries. With the help of new tools, such as teledermoscopy referrals between primary health care and dermatology clinics, the management of these patients could be made more efficient. Objective: To evaluate the diagnostic agreement and interobserver concordance achieved when asses
Shaken baby syndrome has typically been associated with findings of subdural haematoma, retinal haemorrhages and encephalopathy, which are referred to as the triad. During the last decade, however, the certainty with which the triad can indicate that an infant has been violently shaken has been increasingly questioned. The aim of this study was to determine the diagnostic accuracy of the triad in
This book, which presents a cognitive-semiotic theory of cultural evolution, including that taking place in historical time, analyses various cognitive-semiotic artefacts and abilities. It claims that what makes human beings human is fundamentally the semiotic and cultural skills by means of which they endow their Lifeworld with meaning. The properties that have made human beings special among ani
Since the seriousness and urgency of climate change has surfaced during the last decade, researchers, experts, and even the pope have argued that dealing with it is a moral issue. However, emissions keep rising and it seems as if few people in the north are ready and willing to make any substantial lifestyle changes to minimize the potentially catastrophic consequences, mainly to the south. Intern
The publication of 'A darker side of hypermobility' (Cohen and Gössling, 2015), which reviewed the personal and social consequences of frequent travel, led to considerable media coverage and sparking of the public imagination, particularly with regards to the impacts of business travel. It featured in more than 85 news outlets across 17 countries, engendering over 150,000 social media shares and 4
Guayusa (Ilex guayusa) is a native tree of the western Amazon region grown by indigenou farmers in traditional agroforestry systems. Its leaves are used as a drink similar to tea, which is now commercialized and marketed outside of the Amazon. To assess the impacts from theearly stages of commercial guayusa production, we conducted interviews in four commercial guayusa-producing communities with
Deterministic lateral displacement (DLD) is a promising method for particle separation in the micrometer range, the proof of principle of which has been demonstrated to be successful in fields such as biomedicine and physics [1]. However, the enhanced particle dispersion (Figure 1 & 2) arising when separating very small particles (such as viruses and proteins) constitutes the main functional b
Context: Miniaturized instruments for percutaneous nephrolithotomy (PNL), utilizing tracts sized ≤22 Fr, have been developed in an effort to reduce the morbidity and increase the efficiency of stone removal compared with standard PNL (>22 Fr). Objective: We systematically reviewed all available evidence on the efficacy and safety of miniaturized PNL for removing renal calculi. Evidence acquisition
We make Deterministic Lateral Displacement (DLD) flexible by combining it with AC electrokinetics.
The Star-C is a new multilevel converter topology that is characterized by presenting a close to perfect sinusoidal output voltage. Its main purpose is to reduce the electromagnetic emissions that can interfere with other equipment placed nearby and to provide a high output power quality without the need of external filters. At the same time, the Star-C requires a significantly lower amount of com
