Soil and rhizosphere microorganisms have the same Q(10) for respiration in a model system

We compared the Q10 relationship for root-derived respiration (including respiration due to the root, external mycorrhizal mycelium and rhizosphere microorganisms) with that of mainly external ectomycorrhizal mycelium and that of bulk soil microorganisms without any roots present. This was studied in a microcosm consisting of an ectomycorrhizal Pinus muricata seedling growing in a sandy soil, and

Monte Carlo study of TLD measurements in air cavities

Thermoluminescent dosimeters (TLDs) are used for verification of the delivered dose during IMRT treatment of head and neck carcinomas. The TLDs are put into a plastic tube, which is placed in the nasal cavities through the treated volume. In this study, the dose distribution to a phantom having a cylindrical air cavity containing a tube was calculated by Monte Carlo methods and the results were co

Deposition of HfO2 on InAs by atomic-layer deposition

Metal-oxide-semiconductor (MOS) capacitors are formed on bulk InAs substrates by atomic-layer deposition (ALD) of HfO2. Prior to film growth, InAs substrates receive a wet-chemical treatment of HCl, buffered HF (BHF), or (NH4)(2)S. Hafnium dioxide films are grown using 75 ALD cycles with substrate temperatures of 100, 200, and 300 degrees C. Substrate temperature is found to have a significant inf

The influence of RBE variations in a clinical proton treatment plan for a hypopharynx cancer

Currently, most clinical range-modulated proton beams are assumed to have a fixed overall relative biological effectiveness (RBE) of 1.1. However, it is well known that the RBE increases with depth in the spread-out Bragg peak (SOBP) and becomes about 10% higher than mid-SOBP RBE at 2 mm from the distal edge (Paganetti 2003 Technol. Cancer Res. Treat. 2 413-26) and can reach values of 1.3-1.4 in v

Nicotine replacement therapy, professional therapy, snuff use and tobacco smoking: a study of smoking cessation strategies in southern Sweden

Objectives: The strategies used to support smoking cessation among quitters were investigated according to year of smoking cessation and sociodemographic characteristics. Methods: The 2004 public health survey in Skane, Sweden, is a cross-sectional study. A total of 27 757 people aged 18-80 answered a postal questionnaire. The participation rate was 59%. Different strategies to support smoking ces

Balanced chromosome abnormalities inv(16) and t(15;17) in therapy-related myelodysplastic syndromes and acute leukemia: Report from an international workshop

The Workshop identified 48 unselected patients with therapy-related myelodysplastic syndrome or acute myeloid leukemia (t-MIDS/t-AML) and inv(16), and 41 patients with t(15; 17) after chemotherapy (CT) and/or radiotherapy (RT) for a malignant or nonmalignant disease. The primary diseases were: breast cancer, 33 patients; lymphomas, 24 patients; various other solid tumors, 30 patients; and nonmalig

Influence of initial C/N ratio on chemical and microbial composition during long term composting of straw

Shredded straw of Miscanthus was composted in 800-L boxes with different amounts of pig slurry added as nitrogen source. The impact of the different initial CIN ratios (11, 35, 47, 50, and 54) on the composting process and the end product was evaluated by examining chemical and microbiological parameters during 12 months of composting. Low initial C/N ratios caused a fast degradation of fibers dur

Coping with complexity. Sociocybernetics as a Framework for Communication Management

Many models currently discussed in PR studies lack a supporting meta-theory of what managing communication is about, and consequently paint a simplistic picture of what communicating with publics or managing phenomena such as reputation actually means. While it is common to speak of “building” trust or “constructing” images, “cultivating” seems a more appropriate metaphor. Publics are complex, dyn

Converging migration routes of Eurasian hobbies Falco subbuteo crossing the African equatorial rain forest.

Autumn migration of adult Eurasian hobbies Falco subbuteo from Europe to southern Africa was recorded by satellite telemetry and observed routes were compared with randomly simulated routes. Two non-random features of observed routes were revealed: (i) shifts to more westerly longitudes than straight paths to destinations and (ii) strong route convergence towards a restricted area close to the equ

Turbulent flow and heat transfer in a square-sectioned U-bend

Turbulent flow and heat transfer in a square-sectioned U-bend are investigated. Turbulence models with linear and non-linear expressions for the Reynolds stresses are used. The near wall turbulence is treated by the damping functions approach and a two-layer model with Wolfshtein's sub-layer treatment. The inlet conditions have a significant effect on the predictions. The results from the non-line

How often is a low 5-min Apgar score in term newborns due to asphyxia?

Objective: To evaluate how often low 5-min Apgar scores (AS(5-min)) at term are associated with asphyxia. Study design: A cohort- and case-control study, including all 183 term infants with AS(5-min) below 7 born at Lund University Hospital during 1993-2002, antepartum deaths excluded. The control group included 183 randomly selected term newborns with AS(5-min) 9-10. Cardiotocography (CTG) traces

Social capital, trust in the health-care system and self-rated health: The role of access to health care in a population-based study.

This paper investigates the relationship between institutional trust in the health-care system, i.e. an institutional aspect of social capital, and self-rated health, and whether the strength of this association is affected by access to health-care services. The 2004 public health survey in the Scania region of Sweden is a cross-sectional study; a total of 27,963 respondents aged 18–80 years answe

Features associated with epilepsy in the antiphospholipid syndrome

OBJECTIVE: To assess the frequency of epilepsy in primary and secondary antiphospholipid syndrome (APS); to analyze the clinical and laboratory features characterizing those with epilepsy in a cohort of 538 patients with APS; and to find associated features that would suggest risk factors for epilepsy in APS. METHODS: We analyzed the clinical features of patients with APS who had epilepsy and comp

Conditions related to solubility of rare and minor elements in forest soils

Soil solutions expelled by high-speed centrifugation (13900 g) of intact soil sample cores at field moisture froth 30 forest topsoils (A horizons of mainly Dystric and Eutric Cambisols, according to the FAO-Unesco system) low in day, were subjected to, analysis of 60 elements, using ICP-MS and ICP-AES. Concentrations measured were related to soil, and soil solution, properties, assumed to be impor

Degranulation status of airway tissue eosinophils in mouse models of allergic airway inflammation

Eosinophil degranulation is a characteristic feature of asthma and allergic rhinitis. However, degranulated eosinophils have not been convincingly demonstrated in the common mouse models of these airway diseases. This study uses eosinophil peroxidase (EPO) histochemistry and transmission electron microscopy (TEM) analysis to assess eosinophil degranulation in the airways of ovalbumin (OVA)-sensiti
