A non-local gradient-based damage formulation within a geometrically non-linear setting is presented. The hyperelastic constitutive response at local material point level is governed by a strain energy which is additively composed of an isotropic matrix and of an anisotropic fibre-reinforced material, respectively. The inelastic constitutive response is governed by a scalar [1–d]-type damage formu

The heterogeneous group of T-cell lymphomas consist mostly of aggressive diseasess, with generally unfavourable outcome compared to aggressive B-cell lymphomas following similar therapy. This thesis focus on outcome and risk factors for inferior survival, in an unselected population-based cohort of T-cell lymphoma patients. In the first study, outcome of the precursor malignancy T-cell Lymphoblast

Objectives: This study aims to assess patient outcomes and aortic remodelling following coverage of the proximal entry tear with an endograft in complicated acute type B aortic dissections (caTBADs). Material and methods: All patients with caTBAD treated with a thoracic endograft in three high-volume vascular centres were retrospectively studied. Inclusion criteria were branch-vessel malperfusion,

Background: Epidemiologic data suggest that diet is a risk factor in the etiology of gastric cancer. However, the role of dietary fatty acids, a modifiable risk factor, remains relatively unexplored. Objective: The objective of this study was to determine the association of plasma phospholipid fatty acid concentrations, as biomarkers of exogenous and endogenously derived fatty acids, with the risk

Carbon transfer between plants via a common extraradical network of arbuscular mycorrhizal (AM) fungal hyphae has been investigated abundantly, but the results remain equivocal. We studied the transfer of carbon through this fungal network, from a Medicago truncatula donor plant to a receiver (1) M. truncatula plant growing under decreased light conditions and (2) M. truncatula seedling. Autotroph

Objective: People with severe mental illness are often successful in gaining work when participating in the evidence-based Individual Placement and Support (IPS) approach. Little evidence exists on how starting work is perceived by IPS participants. This qualitative study aimed to explore how IPS participants perceived working and the work environment to impact on their work performance. Method

Soil gas production processes, mainly anaerobic or aerobic soil respiration, drive major gas fluxes across the soil-atmosphere interface. Carbon dioxide (CO2) effluxes, an efflux which in most ecosystems is a result of both autotrophic and heterotrophic respiration, in particular have received international attention. The importance of both CO2 and methane (CH4) fluxes are emphasised in the Arctic

The Siljan impact structure in Sweden is the largest confirmed impact structure in Western Europe. Despite this, the structure has been poorly studied in the past, and detailed studies of shock metamorphic features in the target lithologies are missing. Here, we present the results of a detailed systematic search for shock metamorphic features in quartz grains from 73 sampled localities at Siljan.

Snow cover plays a major role in the climate, hydrological and ecological systems of the Arctic and other regions through its influence on the surface energy balance (e.g. reflectivity), water balance (e.g. water storage and release), thermal regimes (e.g. insulation), vegetation and trace gas fluxes. Feedbacks to the climate system have global consequences. The livelihoods and well-being of Arcti

All birds were counted along six permanent routes (total length 90 km) located in the low alpine zone (800–1000 m.a.s.l.) at Ammarnäs, southern Lapland, during fortyyears, 1972–2011. Eighty-three species were recorded; average 41 species and 1677 birds per year. Number of species as well as population size increased for waterfowl, waders and other non-passerines but not for passerines. Thirteen of

Proteins extracted from the seeds of Moringa trees are effective flocculents for particles dispersed in water and are attractive as a natural and sustainable product for use in water purification. Studies with a model system consisting of polystyrene latex particles have shown that the protein adsorbs to the surface and causes flocculation as unusually dense aggregates. Small-angle neutron scatter

This article discusses the ability of information criteria toward the correct selection of different especially higher-order generalized autoregressive conditional heteroscedasticity (GARCH) processes, based on their probability of correct selection as a measure of performance. Each of the considered GARCH processes is further simulated at different parameter combinations to study the possible eff

Mesenteric vein thrombosis has a similar clinical course as arterial, although more prolonged. In the majority of cases conventional anticoagulant treatment should be used and is often successful. The duration should be at least 6 months. Thrombolysis has been used, both systemic and local, although only in small series. Surgery is indicated when there is peritonitis, when often bowel resection is

Objective. GFR-prediction equations based upon cystatin C and creatinine have better diagnostic performance in estimating GFR than equations based upon only one of the two markers. The present work concerns in what way a comparison between separate estimations of GFR based upon cystatin C (eGFR(cystatin C)) or creatinine (eGFR(creatinine)) can be used to evaluate the diagnostic performance of a co

A phenomenological model for explaining the magnetic properties of MnAs nanocrystals embedded in GaAs is proposed. It is shown that experimental data of DC magnetization as a function of temperature, obtained according to zero-field-cooled and field-cooled protocols, can be understood assuming a transition of the system from a low temperature state in which very slow dynamics is observed(frozen st

In the robotic manipulation context, end-effector contact forces may be difficult to measure mainly due to the tool dynamic interferences Such as the inertial forces. In this paper, a whole methodology is proposed to estimate these forces. The new approach is based oil a sensor fusion technique that integrates the information of a wrist force sensor. of a 3D accelerometer placed at the robot tool

Galiellalactone (GL) is a fungal metabolite that presents antitumor activities on prostate cancer in vitro and in vivo. In this study we show that GL induced cell cycle arrest in G2/M phase, caspase-dependent apoptosis and also affected the microtubule organization and migration ability in DU145 cells. GL did not induce double strand DNA break but activated the ATR and ATM-mediated DNA damage resp
