In this paper a simple analytical method is introduced for calculating the overall thermal conductivity of a twin pipe in district heating network. The method is developed based on calculating the conductive and convective heat transfer around the casing pipe in different perimetral sections. Temperature inside the supply and return pipes and also over the heating pipe is measured on different poi
Adult height and sitting height may reflect genetic and environmental factors, including early life nutrition, physical and social environments. Previous studies have reported divergent associations for height and chronic disease mortality, with positive associations observed for cancer mortality but inverse associations for circulatory disease mortality. Sitting height might be more strongly asso
We documented the annual cycle of the carbon isotopic composition of dissolved inorganic carbon (δ13CDIC) in the water columns of the Skagerrak and Baltic Sea to obtain an increased understanding of the processes involved controlling the carbon isotopic distribution in shelf seas. The lowest δ13CDIC values (-4.9‰) were found in the low-oxygen, brackish Baltic bottom water whereas the highest value
Trees growing at their altitudinal or latitudinal distribution in Fennoscandia have been widelyused to reconstruct warm season temperatures, and the region hosts some of the world’slongest tree-ring chronologies. These multi-millennial long chronologies have mainly beenbuilt from tree remains found in lakes (subfossil wood from lake-shore trees). We used aunique dataset of Scots pine tree-ring dat
Efficient variability management is a key issue in large-scale product line engineering, where products with different propositions are built on a common platform. Variability management implies challenges both on requirements engineering and configuration management. This paper presents findings from an improvement effort in an industrial case study including the following contributions: problem
Objective: To analyze the distribution of 3 collagen types in healthy tympanic membranes, during healing of a perforation, and during infection. Design: Immunohistochemical study of collagen types I, II, and III in the tympanic membranes of healthy rats as well as during healing of a perforation and in the presence of infection with Streptococcus pneumoniae at various time points. Setting: Laborat
RATIONALE AND OBJECTIVES. The authors established a rat model of the twitching reaction to contrast media in striated muscle and investigated the influence of nonionic contrast medium on the twitching reaction regarding the nonionic dimer iodixanol compared with the monomer iohexol and the dimer iotrolan. The authors also studied the influences from the electrolyte additions of iodixanol. METHODS.
Aims/hypothesis Post-translational modifications, such as isomerisation of native proteins, may create new antigenic epitopes and play a role in the development of the autoimmune response. Protein-L-isoaspartate (D-aspartate) O-methyltransferase (PIMT), encoded by the gene PCMT1, is an enzyme that recognises and repairs isomerised Asn and Asp residues in proteins. The aim of this study was to asse
Background Chitosans of high molecular weights have emerged as efficient. nonviral gene delivery systems, but the properties and efficiency of well-defined low molecular weight chitosans ((.) 5 kDa) have not been studied. We therefore characterized DNA complexes Of Such low molecular weight chitosans and related their physical shape and stability to their efficiency as gene delivery systems in vit
A method is presented on how to quantify the moisture conditions of nuclear concrete containment walls. The method is based on first quantifying the boundary conditions at the outer and inner surfaces and then describing the moisture fixation and moisture transport within the concrete wall. The temperature and humidity conditions of the outdoor air and of the air close to the wall surfaces are mon
Peripheral nerve (PN) isografts provide a favourable environment for axon regeneration after peripheral and central nervous system (CNS) injury, but definitive information on the extent of cellular intermixing between donor and host tissues is lacking. We wished to compare migration patterns in fresh and predegenerate PN grafts, and also compare the extent of cell migration after transplantation t
The purpose of this study was to develop a new completely automated method for the interpretation of ventilation-perfusion (V-P) lung scintigrams for the diagnosis of pulmonary embolism. A new way of extracting features, characteristic for pulmonary embolism is presented. These features are then used as input to a Support Vector Machine, which discriminates between pulmonary embolism or no embolis
Background. The Gross Motor Function Measure (GMFM) is the instrument most commonly used to measure gross motor function in children with cerebral palsy (CP). Different scoring options have been developed, and their measurement properties have been assessed. Limited information is available regarding longitudinal construct validity. Objective. The objective of this research was to study the longit
The social-democratic-inspired “Nordic model”, with its agenda for gender equality, has been an important example for the development of political interventions to transform society but at the same time, it has functioned as an emerging gender normalising and stabilising structure. In the last decade it has also become the focus of antigender movements and ethno-nationalistic parties both as emble
Searches for dijet resonances with sub-TeV masses using the ATLAS detector at the Large Hadron Collider can be statistically limited by the bandwidth available to inclusive single-jet triggers, whose data-collection rates at low transverse momentum are much lower than the rate from standard model multijet production. This Letter describes a new search for dijet resonances where this limitation is
