A containment scale-model test, performed at Sandia National Laboratories, was loaded by overpressurization and the first leak was concluded to be caused by tears in the steel liner found near the equipment hatch. These tears were located in the vicinity of the vertical fold in between the general curved part and the embossment (vertical bend line). A 3D finite element analysis of the region near
Patients with severely deforming rheumatoid arthritis and impaired function of the upper extremity are often unable to use conventional walking aids. This report describes 42 such patients who were equipped with altogether 75 individually manufactured, lightweight walking aids (12 crutches, 12 forearm-crutches, 39 crutch-sticks and 12 sticks). A plaster cast of the patient's grip as well as analys
BACKGROUND. The objective of the current study was to compile prospective, population-based data on cutaneous invasive melanomas in Sweden during the period from 1990 to 1999, to describe and analyze survival data and prognostic factors, and to make comparisons with previously published Swedish and international data. METHODS. Twelve thousand five hundred thirty-three patients, which included 97%
An ab initio study of the role of electronic curve crossing of benzene S-1 state in the photo dissociation dynamics of the iodobenzene and effect of fluorination is presented. Two dissociative life times observed in iodobenzene is attributed to the coupled repulsive potential energy curves of the low-lying n-sigma*, pi-sigma*, pi-pi* states. The direct channel is attributed to the alkyl like trans
Losses of pelagic diatom production resulting from silica limitation have not only been blamed for toxic algal blooms, but for the reduction in ability of coastal food webs to support higher trophic levels. Recent research has shown the importance of advective seepage water fluxes of dissolved silica (DSi) from freshwater marshes to pelagic waters during moments of riverine Si-limitation. In this
The flow dynamics of a multiple jet combustor is investigated using large eddy simulation. This particular combustor geometry is designed to mix hot combustion products from a central recirculation zone into the surrounding fuel/air jets. Using proper orthogonal decomposition, a large scale rotation of the central recirculation zone around the combustor axis was identified, though the averaged flo
The workshop was organised to discuss the validity and limitations of existing functional markers of Se status in human subjects and to identify future research priorities in this area. Studies presented as part of this workshop investigated: the bioavailability of Se from different dietary sources; potential functional markers of Se status; individual variation in response to Se; the effect of ma
The extant mammalian groups Monotremata, Marsupialia and Placentalia are, according to the ‘Theria’ hypothesis, traditionally classified into two subclasses. The subclass Prototheria includes the monotremes and subclass Theria marsupials and placental mammals. Based on some morphological and molecular data, an alternative proposition, the Marsupionta hypothesis, favours a sister group relationship
BACKGROUND: Morphologic examination of bone marrow and peripheral blood samples continues to be the cornerstone in diagnostic hematology. In recent years, interest in automatic leukocyte classification using image analysis has increased rapidly. Such systems collect a series of images in which each cell must be segmented accurately to be classified correctly. Although segmentation algorithms have
The interactions between wild-type or mutant recombinant forms of human cystatin C and rat cathepsin B were characterized by measuring progress curves for substrate hydrolysis in the presence of inhibitor. The investigation was guided by the use of computer modeling and explores the possibility that amino acid residues in the N-terminal region of cystatin C interact with substrate-binding regions
This is the first of two articles dealing with fluid flow in compressible porous media. In this article a model describing fluid flow and pressure-induced variations in porosity under stationary conditions is developed. In a forthcoming article the dynamic behavior during filtration and wet pressing of compressible porous media are presented. Fluid flow through rigid porous media is generally desc
OBJECTIVES: To determine whether orthostatic hypotension (OH) is more common in patients with dementia than in older people without cognitive impairment and to identify key differences in the profile of the orthostatic response and the pulse drive during orthostatic challenge between Alzheimer's disease (AD) and dementia with Lewy bodies (DLB). METHODS: The orthostatic response was evaluated in 23
Background/Aims: We have observed a difference between patients on low-flux hemodialysis (HD) or peritoneal dialysis and patients on hemodiafiltration (HDF) or high-flux HD in the capacity of transmigrated leukocytes to mobilize CD11b in response to inflammatory stimuli compared with healthy subjects. This could be due to different interstitial chemokine concentrations. Methods: We measured concen
Empirical research elucidating the relationships between aspects of functional competence and environmental factors is lacking. This study aimed to analyse how functional limitations in the individual and housing accessibility problems influence ADL dependence in the elderly population, and to test Lawton's docility hypothesis. Data were collected from 133 Swedish subjects aged 75–84, who were liv
1. We studied the resting metabolic rate (MR) from two great tit Parus major (Linnaeus) populations living in different winter regimes. Birds from the two different localities were exposed individually to +25 °C, 0 °C and −10 °C for the night in three consecutive sessions in random order. 2. Birds from Lund (Sweden) had a lower basal MR, as measured at thermoneutrality (+25 °C), than had birds fr
This article considers the social organization of responses among human service staff to changes in public policy, using a study of a Swedish treatment center for juveniles as an illustration. The stance toward a new treatment ideology, "family-work," was not one of either accepting or rejecting the new policy; the staff conveyed both embracing and distancing. Policy innovations, it is argued, cre
Nociceptin-immunoreactive cellbodies were detected in the human trigeminal ganglion, while no such fibers were identified in the temporal artery or in dermal tissue from the neck region. In four healthy subjects receiving nociceptin into the temporal muscle in an open labeled design no pain was detected. In 10 healthy subjects who received 200 pmol of nociceptin into tender non-dominant trapezius
