Coherent phenomena have been widely suggested to play a role in efficient photosynthetic light harvesting and charge separation processes. To substantiate these ideas, separation of intramolecular vibrational coherences from purely electronic or mixed vibronic coherences is essential. To this end, polarization-controlled two-dimensional electronic spectroscopy has been shown to provide an effectiv

Introduction: The aim was to create readily available algorithms that estimate the individual risk of β-amyloid (Aβ) positivity. Methods: The algorithms were tested in BioFINDER (n = 391, subjective cognitive decline or mild cognitive impairment) and validated in Alzheimer's Disease Neuroimaging Initiative (n = 661, subjective cognitive decline or mild cognitive impairment). The examined predictor

During recent years there has been an increasing demand for better operation of wastewater treatment plants in order to guarantee satisfactory effluent quality at minimal cost. The renewed interest in instrumentation and control comes after a period of huge investments in sewer networks and treatment plants. Several factors have contributed to the potential for better operation and control, such a

Mellan 1918 och 1922 infördes allmän och lika rösträtt i Sverige. När riksdagen inleder sitt hundraårsfirande av rösträtten i december 2018 utkommer denna populärvetenskapliga forskarantologi med texter av statsvetare, historiker, ekonomhistoriker, medieforskare, genusvetare och konstvetare. I tre delar, om bakgrunden, utvecklingen under 1900-talet och framtiden, berättar författarna om processern

A typical polymer electrolyte fuel cell (PEFC) flow field consists of micro/minichannels. The continues removal of liquid water from the cathode channels is a critical topic, as water droplets forming in the channels may block the transport of gaseous oxygen to the active sites, which not only gives an uneven current distribution and substantial loss of performance, but also, increases degradation

Hemicellulose is a promising renewable raw material for the production of hydrogels. This polysaccharide exists in large amounts in various waste streams, in which they are usually impure and heavily diluted. Several downstream processing methods can be combined to concentrate and purify the hemicellulose. However, such an approach can be costly; hence, the effect of impurities on the formation an

I artikeln undersöker jag skådespelarens arbete som ”förkroppsligad subjunktivitet”, dvs från aspekten ”vad skulle jag göra om jag var i rollfigurens situation”?Jag diskuterar detta i relation till en enaktiv teori om social interaktion, nämligen den om ”Participatory sense-making”, (”deltagande meningsskapande”), som utvecklats av Hanne de Jaegher och Ezequiel Paolo. Med exempel hämtade ur en kän

Purpose: Chronic wounds are a major public health challenge, but little is known about the true burden with studies reporting different estimates because of disparities in study designs and measurement methods. This hampers efficient resource allocation, planning, and improvement of wound care. Methods: Our study aimed to pool prevalence estimates from a global perspective by systematically carryi

The ongoing emission of greenhouse gases (GHGs) is triggering changes in many climate hazards that can impact humanity. We found traceable evidence for 467 pathways by which human health, water, food, economy, infrastructure and security have been recently impacted by climate hazards such as warming, heatwaves, precipitation, drought, floods, fires, storms, sea-level rise and changes in natural la

Early results of mitral valve replacement were reviewed in 336 unselected patients, 261 without and 75 with concomitant coronary artery bypass grafting (MVR and MVR + CABG groups). Early (less than 30 days) mortality was 7% in the MVR and 16% in the MVR + CABG group, with cardiac failure as the dominant cause. In multivariate analysis, the variables most strongly related to early mortality were co

Purpose: Patients with brain tumors constitute a vulnerable group, and it is important that they receive the highest quality of care (QoC). The study aim was to describe the perceptions of QoC and its association with health-related quality of life in brain tumor patients undergoing proton beam therapy in a newly established clinic. Method: Data were collected at the start of treatment and after 3
