It is shown theoretically that a claim in the literature about the overall separation efficiency of asymmetrical flow FFF channels being improved by geometries that permit a uniform channel flow velocity throughout the channel length is untrue.
It is postulated that exocrine pancreatic insufficiency (EPI) can evoke neurological disorders. In the present study pancreatic-like enzymes of microbial origin (PLEM) were examined as a functional food component, with the goal of improving cognitive function and brain structure in a pig model of EPI. EPI in the present study induced alterations in the behaviour of the pigs as well as degenerative
Most findings on the triple helix system derive from studies based on high-tech sectors, and seldom so on traditional industries. A foresight exercise aimed at renewal of the mature food industry in the Skåne region in southern Sweden was conducted in 2006-2007. The findings suggest that a multilevel triple helix policy ought to be used in a systemic way from a bottom up perspective, including com
Contagious yawning has been reported for humans, dogs and several non-human primate species, and associated with empathy in humans and other primates. Still, the function, development and underlying mechanisms of contagious yawning remain unclear. Humans and dogs show a developmental increase in susceptibility to yawn contagion, with children showing an increase around the age of four, when also e
LACM 128319, which was collected in western Kansas, U. S. A., and is assignable to Platecarpus tympaniticus (Mosasauridae, Plioplatecarpinae), represents arguably one of the most exquisite mosasaur specimens known to date. Measuring 5.67 m from the tip of the snout to the end of the tail, it comprises an exceptionally well-articulated skeleton, accompanied by soft-tissue remains, such as skin impr
In this empirical study, we have shown that adhesion of dairy products such as fermented milk and yoghurt on packaging materials is dependent on the product contact time to the surface. Approximately 10% of all fermented milk products remain on the inside of today's packaging material. The viscosity of the product seems to have a major effect on how much product that will be adhered to the surface
There have been no reports on the effect of immigrant status and socioeconomic status on outcome in rheumatoid arthritis (RA) in Sweden.
The opportunistic human pathogen Pseudomonas aeruginosa controls host innate immune and complement attack. Here we identify Dihydrolipoamide dehydrogenase (Lpd), a 57 kDa moonlighting protein, as the first P. aeruginosa protein that binds the two human terminal pathway inhibitors vitronectin and clusterin. Both human regulators when bound to the bacterium inhibited effector function of the termina
The thermal insulation of a clothing ensemble can be measured with a thermal manikin or estimated according to ISO 9920. In ISO 9920 there are insulation tables for a number of clothing ensembles with specified garments and other tables for a variety of single garments. The insulation of single garments can be summated to estimate the insulation for a clothing ensemble. However, when a clothing en
Linear enamel hypoplasia (LEH) is transverse lines or bands on the enamel of teeth caused by developmental stress during the formation of the tooth crown. LEH has shown to be useful as a stress marker in studies of health conditions in past populations of pigs. The chronology of LEH and the age at which animals of past populations where afflicted by metabolic stress can be determined based on toot
Asthma patients who continue to experience symptoms despite taking regular inhaled corticosteroids represent a management challenge. Leukotrienes play a key role in asthma pathophysiology, and since pro-inflammatory leukotrienes are poorly suppressed by corticosteroids it seems rational to add a leukotriene receptor antagonist (LTRA) when a low to moderate dose of inhaled corticosteroids does not
To mimic the electron-donor side of photosystem II (PSII), three trinuclear ruthenium complexes (2, 2 a, 2 b) were synthesized. In these complexes, a mixed-valent dinuclear moiety with one phenoxy and two acetato bridges is covalently linked to a RuII tris-bipyridine photosensitizer. The properties and photoinduced electron/energy transfer of these complexes were studied. The results show that the
This report describes laboratory and analytical studies of the chloride migration coefficient, D, defined by Tang, the salt frost scaling, the internal frost resistance and the sulphate resistance of SCC that contains increased amount of filler, different types of casting and different air content.
Controversy surrounds the impact of atmospheric nitrogen (N) deposition on frost hardiness. There are no specific field studies and the relevance of data from N fertilizer studies is questionable. Field N manipulation experiments with Norway spruce [Picea abies . (L) Karst.] at Skogaby, Sweden, and Sitka spruce [P. sitchensis . (Bong.) Carr.] at Aber in Wales and Deepsyke in Scotland were sampled
Photodynamic therapy (PDT) with topical methyl aminolevulinate ( MAL) administered in two treatment sessions separated by 1 week is an effective treatment for actinic keratoses. This open prospective study compared the efficacy and safety of MAL-PDT given as a single treatment with two treatments of MAL-PDT 1 week apart. Two hundred and eleven patients with 413 thin to moderately thick actinic ker
Distributions of tumor necrosis factor (TNF) and its soluble receptor forms, R55-BP and R75-BP, were analyzed in the cerebrospinal fluid of patients with severe acute or chronic central nervous system infections. Tuberculous infections were associated with high ratios of R55-BP and R75-BP to TNF, 27.2 and 28.0, respectively, suggesting a small biologically active fraction of TNF. The opposite was
A capillary gas chromatographic (GC) method using selected-ion monitoring (SIM) was developed for the analysis of cotinine (C.A.S. No. 486-56-6) in human urine. The method is based on basic extraction of cotinine from 2 ml of urine into dichloromethane. After evaporation of the dichloromethane solution to dryness, 100 microliters of toluene were added, prior to GC-mass spectrometric (MS) analysis.
This study investigated the influence of habit strength and perceived social norms on Swedish residents continued use of reusable bags following the removal of the plastic bag tax. A cross-sectional survey (N = 93) measured participants’ habit strength, perception of social norms, and frequency of reusable bag usage. Descriptive statistics indicated variability in habit and social norm scores, and
This thesis examines the challenges faced by recent immigrants to Canada in having their educational credentials and work experience recognised within the Canadian labour market. Using Canadian census microdata from 2021, the study assesses the wage gap between immigrants and native-born Canadians, with a specific focus on the returns to educational credentials and work experience for both groups.
