The uncertainty in eddy covariance (EC) flux measurements is assessed for CH4 and N2O using data measured at a dairy farm site in the Netherlands in 2006 and 2007. An overview is given of the contributing uncertainties and their magnitude. The relative and absolute uncertainty of a 30 min EC flux are estimated for CH4 and N2O using N = 2185 EC fluxes. The average absolute uncertainty and its stand

OBJECTIVE: The aim of the study was to examine the double locked-in phenomenon at work (i.e., being in a non-preferred occupation and non-preferred work place), and its associations to psychological health, physical health and job satisfaction. METHODS: A total of 136 municipal employees who visited a career coaching center (response rate 59%) participated in the questionnaire study. RESULTS: The

Entanglement evolution is studied in open systems represented by rings of qubits with the Ising interaction and variously oriented external field and with Markov environments. The effect of thermal or dephasing environment is manifested as exponential decrease of the entanglement superposed on its dynamics in the isolated system. (C) 2009 Elsevier B.V.

One of the major symptoms of the neurodegenerative condition Parkinson's disease (PD) is a slowness or loss of voluntary movement, yet frustratingly therapeutic strategies designed to restore movement can result in the development of excessive abnormal movements known as dyskinesia. These dyskinesias commonly develop as a result of pharmacotherapy in the form of L-DOPA administration, but have als

The main objectives of the work presented in this thesis were to develop new experimental methods to improve the understanding of the release mechanism from a coated formulation and to develop new mechanistic models to describe the release process for pellets coated with a semi-permeable film. Another aim was to characterize the release mechanism from a formulation coated with films made of a blen

Aims: To analyze the nonspecific chronic orofacial pain patient's experience of the pain condition and to gain knowledge on the complexity of the problem. Methods: Fourteen patients (1 I female, 3 male) aged 21 to 77 years were selected among those referred to a specialist clinic. All selected patients agreed to participate. Data were obtained through thematic in-depth interviews that exposed the

Background. To study group B streptococcus (GBS) colonisation in parturients and infants in relation to obstetric outcome and to define serotypes and antibiotic resistance in GBS isolates acquired. Methods. A population-based, national cohort of parturients and their infants was investigated. During 1 calendar week in 2005 all women giving birth (n=1,754) were requested to participate in the study

This article discusses the political use of the fall of the Roman empire and in particular the way this historical motif has been utilized in environmental debates and in US political culture. It is furthermore argued that the historiography of the fall of the Roman empire bears witness to the ideological and existential contexts of specific explanations to why Rome fell.

Purpose - Even though noticeable improvements have been made in global health in recent years, the distribution is uneven throughout the world and many developing and low-income countries lack access to required medicine and vaccines. Thus, a model to strategically source vaccines for these nations can contribute a great deal. This paper presents an extensive review of strategic sourcing literatur

Parasites exert important top-down control of their host populations. The host-parasite system formed by Alexandrium minutum (Dinophyceae) and Parvilucifera sinerae (Perkinsozoa) offers an opportunity to advance our knowledge of parasitism in planktonic communities. In this study, DNA extracted from 73 clonal strains of P. sinerae, from 10 different locations along the Atlantic and Mediterranean c

Abstract in UndeterminedMeasurements of dielectric permittivity and electrical conductivity were taken in a saline gypsiferous soil collected from southern Tunisia. Both time domain reflectometry (TDR) and the new WET sensor based on frequency domain reflectometry (FDR) were used. Seven different moistening solutions were used with electrical conductivities of 0.0053-14 dS m(-1). Different models

Here we detail high performance, enzymatic electrodes for oxygen bio-electroreduction, which can be easily and reproducibly fabricated with industry-scale throughput. Planar and nanostructured electrodes were built on biocompatible, flexible polymer sheets, while nanoimprint lithography was used for electrode nanostructuring. To the best of our knowledge, this is one of the first reports concernin

Fires can be an important hazard for the overall safe operation of nuclear power plants. Prevention of fire, fast detection and efficient extinguishment of a fire are some parameters, which are important to consider when designing the fire safety in a nuclear power plant. As an alternative to extinguishment system the use of hypoxic air or hypoxic air venting has been introduced e.g. in storage ro

Socio-technical methods advocate a human-focus analysis that reflects on social and technical factors in the design of organizational systems. The aim of this paper is to report on the experiences of a ST toolbox use in practice by 36 companies. Our findings show that the use of ST toolbox improves companies’ understanding of their job practices and enhance their learning about their business sust

Objectives. To study treatment response rates of RA patients undergoing second- and third-line anti-TNF therapy and to identify baseline predictors of response to second-line treatment. Methods. RA patients monitored in a prospective, observational study, having switched anti-TNF therapy once (first-time switchers, n = 337) or twice (second-time switchers, n = 36)-i.e. following failures with one

Objectives. Venous thromboembolism (VTE) is a potentially serious complication of hospitalization and immobilization. The use of anticoagulant prophylaxis in acutely ill medical inpatients is still under debate. New data including a recent meta-analysis have recently been published. We aim at studying the efficacy and safety of anticoagulant prophylaxis in acutely ill medical inpatients, and demon

Milk casein concentrates with different casein-to-protein ratios (0.82 and 0.93), pH (5.8, 6.2 and 6.7) and level of applied ultra-high pressure homogenisation (UHPH) (0, 150 and 300 MPa) were studied. Samples with a casein-to-protein ratio of 0.93 at pH 5.8 and subjected to UHPH treatment at 300 MPa had the highest apparent viscosity and particle size followed by similar samples with a casein-to-

Females of the Indian meal moth, Plodia interpunctella, and females of the Mediterranean flour month, Ephestia kuehniella (both Lepidoptera: Pyralidae), exhibit daily rhythms in calling behavior. The peak in P. interpunctella calling occurs at dusk, whereas E. kuehniella calls preferentially at dawn. This behavior turned arrhythmic in P. interpunctella females in constant darkness (DD) and remaine

Dominance can be maintained through status recognition or recognition of individual (familiar) opponents. In crustaceans, both types of recognition exist, often based on chemical signals. Fight behaviours involved in establishment and maintenance of dominance relationships in male and female European lobster (Homarus gammarus) were examined. Same-sex pairs of size-matched animals interacted on two
