Monte Carlo calculations of thermal neutron capture in gadolinium : A comparison of GEANT4 and MCNP with measurements

GEANT4 is a Monte Carlo code originally implemented for high-energy physics applications and is well known for particle transport at high energies. The capacity of GEANT4 to simulate neutron transport in the thermal energy region is not equally well known. The aim of this article is to compare MCNP, a code commonly used in low energy neutron transport calculations and GEANT4 with experimental resu

Gruppdagbok i forskning och praktik – en metod för gruppstudier

A new method for collection of group data is described— Group Diary. Document studies in psychology are a background. Group members collect data as recorders and synthesize their notes. The method is a tool for learning, research and consultation. Methodological issues are elucidated. After presentation of five studies on group formation and development done by the authors, the pros and cons of th

Symbolisk organisering : En studie av organisatorisk förändring och meningsproduktion i fyra industriföretag

Popular AbstractI den här avhandlingen behandlas dels hur själva organiseringens processer kan gestalta sig, dels innehållet i några av de studerade processerna. Det empiriska materialet i studien har hämtats från fyra industriföretag som alla under 1990-talets första år genomförde försök att utveckla en mera processorienterad arbetsorganisation. Tre av företagen ingår i globala koncerner. Det fjäThe focus of this dissertation is on organizational change in four industrial corporations. A special emphasisis placed upon the symbolic and rhetorical aspects when changing organizations. Main concepts in the study are symbolic management and management of meaning. Two main areas are discussed in the dissertation. Firstly, how the new organizational meaning is constructed or produced. Secondly,

Tubular and glomerular kidney effects in Swedish women with low environmental cadmium exposure

Cadmium is a well-known nephrotoxic agent in food and tobacco, but the exposure level that is critical for kidney effects in the general population is not defined. Within a population-based women's health survey in southern Sweden (Women's Health in the Lund Area, WHILA), we investigated cadmium exposure in relation to tubular and glomerular function, from 1999 through early 2000 in 820 women (71%

Enhanced radioimmunotargeting of 125I-labeled L6-biotin monoclonal antibody (MAb) by combining preload of cold L6 MAb and subsequent immunoadsorption in rats

The present study investigates whether tumor:normal tissue uptake ratios of radiolabeled monoclonal antibodies can be further improved by a combination of extracorporeal immunoadsorption (ECIA) and preload with unlabeled idiotypic monoclonal antibody. Athymic rats, heterotransplanted with human lung carcinoma under the kidney capsule (SR tumor) and i.m. (IM tumor), were divided into four study gro

Expression of bovine calmodulin in tobacco plants confers faster germination on saline media

Calmodulin is a Ca2+-dependent regulatory protein in eukaryotic cells involved in a variety of intracellular activities. Many responses to abiotic stresses involve signaling by Ca2+ and Ca2+/calmodulin regulation, including water and salinity stress. To investigate how calmodulin affects germination on media with high concentrations of NaCl, transgenic tobacco plants expressing heterologous calmod

Neuron-specific TGF-beta signaling deficiency results in retinal detachment and cataracts in mice

We generated a mouse model (cKO) with a conditional deletion of TGF-beta signaling in the retinal neurons by crossing TGF-beta receptor I (TGF-beta RI) floxed mice with nestin-Cre mice. Almost all of the newborn cKO mice had retinal detachment at the retinal pigment epithelium (RPE)/photoreceptor layer junction of the neurosensory retina (NSR). The immunostaining for chondroitin-6-sulfate showed a

Surface resonance on the (6 root 3 x 6 root 3)-R30 degrees-reconstructed 5 ML Au on (root 3 x root 3)-R30 degrees-4H-SiC(0001)

In this paper we present evidence for a surface resonance on the (6v root 3 x 6 root 3)-R30 degrees-reconstruction obtained on 5 monolayers (ML) of An deposited on the (root 3 x root 3)-R30 degrees-4H-SiC(0001) and subsequently annealed. We use synchrotron radiation-based angle resolved photoelectron spectroscopy to show that this resonance has no k(parallel to)-dispersion, but a parabolic-like ki

Sydsvenska baptister inför myndigheter. Tillämpning av religionsbestämmelser i Lunds och Växjö stift 1857-1862.

Popular Abstract in Swedish Under 1850-talet framträdde baptismen som den första verkliga frikyrkorörelsen i Sverige. Den tog helt och hållet avstånd från det ordinära kyrkolivet och kom därför i konflikt med samhällets religiösa regelverk. Kyrkliga och världsliga myndigheter betrktade baptismen som villfarande och samhällsupplösande. Deras agerande mot baptisterna i landets södra delar blir i denDuring the 1850's, Baptism appeared as the first real free church movement in Sweden. It distanced itself completely from normal church life and therefore came into conflict with society's religious rules. Ecclesiastical and temporal authorities regarded Baptism as erroneous and social disruptive. In the present treatise, their actions against the Baptists in the southern parts of the country beco

Nutritional status among patients with hip fracture in relation to pressure ulcers.

Background & aims Patients with a hip fracture often have a poor nutritional status that is associated with increased risk of complications, morbidity and mortality. The aim of this study was to investigate the effects of an improved care intervention in relation to nutritional status and pressure ulcers. An intervention of best practices for patients with hip fracture was introduced, using t

Structure of ribosomal protein TL5 complexed with RNA provides new insights into the CTC family of stress proteins

The crystal structure of Thermus thermophilus ribosomal protein TL5 in complex with a fragment of Escherichia coli 5S rRNA has been determined at 2.3 Å resolution. The protein consists of two domains. The structure of the N-terminal domain is close to the structure of E. coli ribosomal protein L25, but the C-terminal domain represents a new fold composed of seven -strands connected by long loops.

Allocation of plant carbon to foraging and storage in arbuscular mycorrhizal fungi

Foraging strategies, the cost-benefit associated with the search for new resources, have only begun to be explored in arbuscular mycorrhizal fungi (AMF). We show the use of C-13-labelling, via shoot photosynthesis, of the 16: 1omega5 fatty acid biomarker (the dominant and rather specific fatty acid in AMF storage lipids) to study the immediate patterns of carbon allocation to fungal lipids in resp
