The selective breeding of Roman high- (RHA/Verh) and low-avoidance (RLA/Verh) rats for rapid versus poor acquisition of active avoidant behaviour has produced two behavioural phenotypes with different performances in a variety of animal models of anxiety, in which RLA/Verh rats are consistently more fearful than RHA/Verh rats. In addition, these two lines display different functional properties of

The digestibility of sludge is dependent on the content of organic extra-cellular polymeric substances. Currently the most appropriate and rapid assessment methods for the organic content of wastewater are the chemical oxygen demand and volatile solids values. These parameters also measure the non-biodegradable organics. We have developed a method to predict sewage sludge digestibility and the app

Detta är en antologi som består av exempel på empiriska studier där äldre människors varit involverade som subjekt. Resultatet visar att äldres teknikanvändning i vardagen problematiseras på tre nivåer. den första nivån fokuserar konstruktionen och utformningen av artefakten; den andra nivån användningen av tekniken i den vardagliga kontexten; den tredje nivån relationen mellan teknikutvecklingen

This work introduces a new approach to achieve a unimodal dome-shaped island population for the self-assembled Ge/Si (0 0 1) dots grown by ultra-high vacuum chemical vapour deposition at T = 620 degreesC. A step-wise growth mode is applied, consisting of two Ge deposition steps with a short growth interruption in between. In the first step, a "base structure" with pyramids and domes is grown while

The orchid genus Nigritella constitutes a polyploid complex which is widespread in mountain regions in Europe. Diploid members of the genus have sexual reproduction, whereas polyploid members are characterised by agamospermy. We used allozyme data to estimate levels of variation at different hierarchical levels and to describe the evolution of polyploids. - The variation patterns at allozyme loci

Objective. A low tidal volume can induce alveolar derecruitment in patients with acute lung injury. This study was undertaken to evaluate whether this resulted mainly from the decrease in tidal volume per se or from the reduction in end-inspiratory plateau pressure and whether there is any benefit in raising the level of positive end-expiratory pressure (PEEP) while plateau pressure is kept consta

The growing world electricity demand and environmental concerns pushes toward new technology for electricity production. Within the thermal processes for electricity production, two axis of research are being developed to meet the needs of the industry, namely using renewable fuels and new generation burners technology. The first direction is to develop new processes able to use renewable fuels. B

(1) We have isolated radiolabelled proteoglycans and glycosaminoglycans produced by human embryonic skin fibroblasts in the presence of (a) cycloheximide to inhibit protein synthesis or (b) brefeldin A to impede transport between the endoplasmic reticulum and the Golgi complex or (c) suramin, heparin or primaquine to interfere with internalization, recycling and degradation. Effects on glycosamino

Strained nanowires with varying InAs/InP core/shell thicknesses were grown using Chemical Beam Epitaxy. Microphotoluminescence spectroscopy, performed at low temperature, was then used to study the optical properties of single wires. Emission from the InAs core was observed and its dependence on the shell thickness/core diameter ratio was investigated. We found that it is possible to tune the emis

Transitorisk global amnesi (TGA) är ett godartat tillstånd med akut insättande oförmåga till minnesinprägling, som går i komplett regress inom 24 timmar. TGA förekommer huvudsakligen hos medelålders och äldre personer och anses vara mycket sällsynt hos personer yngre än 40 år. Tre fallrapporter presenteras där TGA drabbat unga män (16–22 år) under fotbollsspel. En litteraturgenomgång visar att mekTransient global amnesia (TGA) occurs mostly in middle-aged and elderly individuals, and is generally believed to be very rare in individuals less than 40 years of age. We present three cases of TGA in young persons (16-22 years). They all had a medical history and presented symptoms fulfilling the criteria for TGA. Physical examinations and investigations were all normal. All three presented thei

In the article, the main theories of Anthony Giddens (structuration and late modernity theory) are presented and applied upon public relations. A review shows that there have been few attempts to use these theories in public relations. The analysis states that using Giddens leads to a questioning of the dichotomy between instrumental agency-oriented theories that neglects power structures as well

This article reports on a parallel implementation of a general 3D multi-block CFD code. The parallelization is achieved by using three strategies. Firstly, it is done on dual-processor PC-clusters where Windows NT systems are running. A multi-thread programming model is adopted for the multi-block code, where one thread corresponds to a block. Shared memory is used for the exchange of inner-bounda

Three-body correlations in the dissociation of two-neutron halo nuclei are explored using a technique based on intensity interferometry and Dalitz plots. This approach provides for the combined treatment of both the n-n and core-n interactions in the exit channel. As an example, the breakup of 14Be into 12Be+n+n by Pb and C targets has been analyzed and the halo n-n separation extracted. Evidence

The dynamic regulation of ligand binding is considered crucial for integrin function. However, the importance of activity regulation for integrin function in vivo is largely unknown. Here, we have applied gene targeting to delete the GFFKR sequence of the lymphocyte function-associated antigen-1 (LFA-1) alpha(L) subunit cytoplasmic domain in mouse germline. Lymphocytes from Lfa-1(d/d) mutant mice
