Sociology of the professions has faced difficulties in delineating and defining the core of its object of study, the concept and phenomenon of profession. Setting out from the so-called French epistemological tradition, this article tries out a new possibility. It is argued that if there are trans-historical elements in professions, they are found at the cognitive side, as a certain reasonably inv
Superficial damage, similar in appearance to salt scaling of concrete, has been observed at the waterline of hydraulic structures, such as hydro power structures, bridge columns, canals and harbours. Progressive damage to the concrete surface results in exposure of coarse aggregate. Deterioration rates of about 1 mm per year have been observed in some cases. A laboratory test method was developed
The catalyst layer (CL) of a proton exchange membrane fuel cell involves various particles and pores that span a wide range of length scales, from several nanometers to a few microns. The success of the CL design depends decisively on understanding the detailed structure in microscale or even in nanoscale. In this paper, the properties of nano-/microstructures are outlined, and the physical and ch
Clinical blood oxygenation level-dependent (BOLD) functional magnetic resonance imaging (fMRI) is becoming increasingly valuable in, e.g., presurgical planning, but the commonly used gradient-echo echo-planar imaging (GE-EPI) technique is sometimes hampered by macroscopic field inhomogeneities. This can affect the degree of signal change that will occur in the GE-EPI images as a response to neural
A previous study by the authors using a heated thermal manikin showed that the cooling rates of phase change material (PCM) are dependent on temperature gradient, mass, and covering area. The objective of this study was to investigate if the cooling effects of the temperature gradient observed on a thermal manikin could be validated on human subjects in extreme heat. The subjects wore cooling vest
The process stability of water-in-oil-in-water (W/O/W) double emulsions stabilized with food-grade OSA modified quinoa starch granules was investigated. The effect of oils with differing melting points, as well as the effect of in situ partial gelatinization of the granules, on stability of emulsions was also investigated. The physical stability and release of a tracer (carmine) from the internal
Abstract in UndeterminedAction plans are an important tool for meeting the EU renewable energy targets. Planning of biomass at national level has recently shifted from biomass action plans to renewable energy action plans; the latter still assigning special attention to biomass. A number of regions have also developed or are developing biomass plans. However, even though such plans are to assist t
Knowledge about the existing safety culture in a maritime organization such as in shipping companies or on board ships can enable the formulation of effective interventions to maintain and improve safety culture and safety in the organization. When assessing the safety culture, questionnaires developed for this purpose are often used. This paper proposes a work process that facilitates the analysi
Genome-wide association studies (GWAS) have identified more than 100 genetic variants contributing to BMI, a measure of body size, or waist-to-hip ratio (adjusted for BMI, WHRadjBMI), a measure of body shape. Body size and shape change as people grow older and these changes differ substantially between men and women. To systematically screen for age- and/or sex-specific effects of genetic variants
Food engineering aspects of cooking of meat products in relation to their biophysical properties, such as water- and fat-holding, have been reviewed. Moreover, some of the new emerging, mild cooking technologies, such as high pressure and electro-based heating (radio frequency cooking and ohmic heating) have been discussed in relation to the biophysical properties of the meat products treated. The
The abuse of flunitrazepam (FZ) compounds is worldwide, and several studies have reflected on the consequences with regard to violence, aggression and criminal lifestyle of FZ users. Criminals take high doses of FZ or some other benzodiazepines to "calm down" before the planned crime. There is support from earlier studies that most likely, all benzodiazepines may increase aggression in vulnerable
This paper explores empirical linkages between cycles and trends in freight transportation activity and real economic activity in Sweden. It decomposes freight demand into short-term, medium-term and long-term components and analyzes differences and similarities of the three time horizons. The finding is that freight demand is coupled with GDP over the long-term and that there are no signs of deco
Aim To assess statistically the relative importance of climate and human impact on forest composition in the late Holocene. Location Estonia, boreonemoral Europe. Methods Data on forest composition (10 most abundant tree and shrub taxa) for the late Holocene (5100-50 calibrated years before 1950) were derived from 18 pollen records and then transformed into land-cover estimates using the REVEALS v
It is commonly acknowledged that an elaborated military pastoral care provided a significant contribution to the efficiency of the Swedish army during the Great Northern War (1700–1721). Usually battle preparations and the chaplains’ efforts to instil morale and discipline among the soldiers are emphasized. In this article my aim is to provide a somewhat different idea on the nature of the religio
Nitrogen (N) is a key element in terrestrial ecosystems as it influences both plant growth and plant interactions with the atmosphere. Accounting for carbon–nitrogen interactions has been found to alter future projections of the terrestrial carbon (C) cycle substantially. Dynamic vegetation models (DVMs) aim to accurately represent both natural vegetation and managed land, not only from a carbon c
Pelvic girdle pain is a frequent cause of sick leave among pregnant women in Denmark. Studies regarding prevention of pelvic girdle pain are sparse. The aim of this study was to examine the association between physical exercise and pelvic girdle pain in pregnancy.
Northern inland waters emit CO2 and CH4 to the atmosphere but the importance of these emissions is poorly understood due to a lack of integrated catchment-scale estimates of carbon (C) emissions from lakes and streams. In this study we quantified the annual emission of CO2 and CH4 from 27 lakes and 23 stream segments in a 15km(2) subarctic catchment in northern Sweden. All lakes and streams were n
