Aiming for a better understanding of the interactions between water suspended cellulose fibres and metal ions, this study was focused on characterising the interactions between Ca2+. Cu2+ and two different fibre materials-a fully bleached softwood Kraft pulp, and a chemically modified fully bleached softwood Kraft fibre material. The study was conducted as a function of pH (2-7), and both in the a
The Swedish Navy has operated submarines equipped with air independent propulsion for two decades. This type of submarine can stay submerged for periods far longer than other nonnuclear submarines are capable of. The air quality during longer periods of submersion has so far not been thoroughly investigated. This study presents results for a number of air quality parameters obtained during more th
In this work we report the coating of a biological template with a polar, but uncharged,luminescent conjugated polymer, soluble in organic solvents but not in water, to produce a nanowire. Amyloid fibrils from bovine insulin were decorated with an alternating polyfluorene derivative. Decorated fibrils were partially aligned on hydrophobic surfaces as separate and bundled fibrils, by means of molec
Background: Circulating monocytes may be subdivided according to the presence or absence of the Fc gamma receptor CD16 and the neural cell adhesion molecule CD56. Monocytes classified into these subpopulations Lire characterized by distinct phenotypic and functional features. We hypothesized that patients with active Crohn's disease differ in their peripheral monocyte subpopulations. Methods: Usin
The Ptiliidae of the Maritime Provinces of Canada is surveyed. Twenty-nine new provincial records from the Maritime Provinces of Canada are reported including the first records of the family from Prince Edward Island. Fourteen species are recorded for the first time for the Maritime Provinces as a whole. Acrotrichis josephi (Matthews) is recorded for the first time in eastern North America and Acr
Since 2001 the School of Dentistry of Malmö University in Sweden has used an alternative procedure based on results of an investigation supported by the Swedish Council for the Renewal of Undergraduate Education. The investigation concerned possibilities of predic¬ting school performance on the basis of an interview, as well as tests of general intelligence, spatial ability, manual dexterity, empa
Previous research suggests that body dissatisfied women are particularly susceptible to negative affect following exposure to thin media images, whereas body satisfied women may even respond positively to such images. It was thus hypothesised that negative self-referent information would be more accessible in body dissatisfied women than in women satisfied with their bodies after viewing thin idea
Bioban P 1487, consisting of the 2 active ingredients 4-(2-nitrobutyl)-morpholine (M) and 4,4'-(2-ethyl-2-nitro-1,3-propanediyl)-bis morpholine (DM), is a preservative recommended for mental working fluids. The aims of this study were to assess the frequency of contact allergy to Bioban P 1487, when added to a standard patch test series, as well as to test the individual active ingredients in pati
arkinson's disease is the second most common neurodegenerative disease. It is charaterized by a progressive loss of dopamine (DA) producing neurons in the midbrain, which result in a decline of DA innervations present in the forebrain, in particular, the striatum. The disease leads to appearance of motor symptoms involving akinesia/bradykinesia, gait disturbances, postural imbalance and tremor. Or
We propose a novel distinguishing attack on the shrinking generator with known feedback polynomial for the generating LFSR. The attack can e.g. reliably distinguish a shrinking generator with a weight 4 polynomial of degree as large as 10000, using 2(32) output bits. As the feedback polynomial of an arbitrary LFSR is known to have a polynomial multiple of low weight, our distinguisher applies to a
This study examined the maturation of cortical auditory event-related potentials (ERPs) from birth until 12 months of age. In the 15 infants studied, all ERP peaks observable at 12 months of age, the P150, N250, P350, and N450 were identifiable already at birth, As in previous studies, the amplitudes of the ERP peaks increased and latencies shortened with increasing age. In addition, the time cour
Bacterial density and the hyphal density of Verticillium dahliae were determined along the roots of sand-grown rape seedlings. Verticillium dahliae microsclerotia were trapped in nylon nets which were placed in front of the growing root tip. The growing hyphae on the nets were stained with fluorescein diacetate and rhodamine B isothiocyanate. Bacteria on the petri dish lids adjacent to the nets we
A dynamic supramolecular system involving hydrogen bonding between a Mn(III) salen catalyst and a Zn(II) porphyrin receptor exhibits selectivity for pyridine appended cis-beta-substituted styrene derivatives over phenyl appended derivatives in a catalytic epoxidation reaction.
Atmospheric air samples were taken within 3 km from power plants encompassing five different distances and wind directions. Samples were taken between 2002 and 2005 aiming to evaluate the environmental C-14 enrichment due to the operation of Brazilian nuclear power plants. The sampling system consisted of a pump connected to a trapping column filled with a 3 M NaOH solution. The trapped C-14 by us
The many-body theory of photoemission in solids is reviewed with emphasis on methods based on response theory. The classification of diagrams into loss and no-loss diagrams is discussed and related to Keldysh path-ordering book-keeping. Some new results on energy losses in valence-electron photoemission from free-electron-like metal surfaces are presented. A way to group diagrams is presented in w
The purpose of this study was to retrospectively evaluate the radiologic findings in young adults with dysphagia undergoing barium swallow and to compare these with the final clinical diagnosis. Clinical history, barium swallow, endoscopy (21 patients), manometry (18 patients), 24 h pH monitoring (4 patients), and outcome of treatments were studied and compared in 43 patients aged 14-30 years (mea
