OBJECTIVES: This study attempts to construct valid indices for mechanical exposure of the shoulder-neck region with relation to the development of shoulder-neck pain in a 1-year perspective study of a general population. METHODS: A comprehensive questionnaire was presented to 14 556 subjects aged 45 or 65 years and repeated after 12 months. Twenty-four questions concerning positions, movements, an
This article analyses the nexus of technocracy-peacebuilding and its implications on water conflicts and hydropolitics. It is a conceptual exploration, which advances an interdisciplinary approach by combining theories from two distinct research fields: peacebuilding and transboundary water management. It probes the argument that synergies between water management, development and peacebuilding fr
An increasing interest in the moisture buffering of indoor surface materials and new tools for calculation of energy demands and indoor climate calls for relevant material properties of all materials exposed to the indoor air. Textile fabric represents a large portion of the surface materials present in dwellings and offices and is therefore of special interest. This paper presents the sorption is
Symptoms of sleep-disordered breathing in children, such as frequent snoring, apnoea and choking, may lead to health problems if untreated. The caregiver's level of awareness of these symptoms has been poorly studied. This study aimed to study healthcare provider contact related to sleep-disordered breathing symptoms in a population of children aged 0-11 years.
We present a compact, fast, and versatile fiber-optic probe system for real-time determination of tissue optical properties from spatially resolved continuous-wave diffuse reflectance measurements. The system collects one set of reflectance data from six source-detector distances at four arbitrary wavelengths with a maximum overall sampling rate of 100 Hz. Multivariate calibration techniques based
Two circulation index-based methods were applied to downscale summer daily rainfall at four meteorological stations in Chongqing, China. One is a regression method (CIM) and the other a hybrid circulation classification plus regression method (CPM). Both methods used the same three circulation indices and surface specific humidity as predictors. In the first method (CIM), the indices and humidity
The onset of walking is a fundamental milestone in motor development of humans and other mammals, yet little is known about what factors determine its timing. Hoofed animals start walking within hours after birth, rodents and small carnivores require days or weeks, and nonhuman primates take months and humans approximately a year to achieve this locomotor skill. Here we show that a key to the expl
The effect of acute intraoperative plateletpheresis (25% platelet yield) in combination with intraoperative low-dose aprotinin (2 million units) on blood conservation was investigated in 18 young adult patients undergoing elective Ross operation. The results were compared with a group of 19 similar patients without plateletpheresis (control group). The hematological and coagulation parameters at a
The transport and gain properties of quantum cascade (QC) structures are investigated using a nonequilibrium Green's function (NGF) theory which includes quantum effects beyond a Boltzmann transport description. In the NGF theory, we include interface roughness, impurity, and electron-phonon scattering processes within a self-consistent Born approximation, and electron-electron scattering in a mea
Accelerator based lightsources are one of the most powerful tools today for producing high intensity radiation at very short wavelengths. While synchrotron storage rings provide a high average brilliance in a wide wavelength range, the next generation of lightsources aim towards producing ultra-short pulses in the X-ray regime. A very promising technique implemented or proposed at many accelerat
BACKGROUND AND AIMS: Monochromatic pulsating light may have effects on wound healing. In an earlier study of grade II ulcers, there was a tendency toward better healing in the phototherapy group (p=0.06). The present study on patients with grade II ulcers was performed to verify these findings. Data from this study were pooled with data from the earlier study. METHODS: Ninety-four patients were of
BACKGROUND: Men with prostate cancer on androgen deprivation therapy (ADT) are at increased risk of bone loss. The present study sought to determine the incidence of low trauma fracture in men with prostate cancer (PC), and to characterize the association between potential risk factors and fracture risk in these men. METHODS: In the prospective, population-based Dubbo Osteoporosis Epidemiology Stu
CONTEXT: Prior studies have demonstrated conflicting results regarding how much information novel biomarkers add to cardiovascular risk assessment. OBJECTIVE: To evaluate the utility of contemporary biomarkers for predicting cardiovascular risk when added to conventional risk factors. DESIGN, SETTING, AND PARTICIPANTS: Cohort study of 5067 participants (mean age, 58 years; 60% women) without cardi
A discussion on whether and why archaeology is important, with Mårup Church (Denmark) as point of departure. The church will soon fall into the sea. Why is it crucial to save or document this church? Rhetorical catchwords, cultural mangagement, archaeology, history and social anthropology are presented and critically examined.
Endotracheal suctioning consists of the mechanical aspiration of pulmonary secretions from the endotracheal tube (ETT) to prevent obstruction. The optimal frequency of ETT suctioning has not been defined.
