Epidemiological studies have shown an increased incidence of cancer among workers occupationally exposed to polycyclic aromatic hydrocarbons (PAHs). As the dermal route is considered important for exposure to PAHs in the workplace, the aim of this study was to develop and evaluate a tape-stripping technique for monitoring dermal exposure to pyrene and benzo(a)pyrene. The tape-stripping method was

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

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

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: 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

OBJECTIVE: The aim of this study was to test the coherence of a wearable device, an inertial measurement unit (IMU) against the gold standard; also, to test the intra-trial reliability. This study has a cross-sectional design, where measurement of postural sway in the medio-lateral and anterior-posterior directions was performed simultaneously on a force plate and with a IMU called the Snubblomete

The shell condenser is a key component for the underwater vehicles. To study its heat transfer performance and flow characteristics and to design a more efficient structure, a mathematical model is generated to simulate condensation inside the straight and helical channels. The model combines empirical correlations and MATLAB based on an it

Solid waste collection and hauling account for the greater part of the total cost in modern solid waste management systems. In a recent initiative, 3,300 Swedish recycling containers have been fitted with level sensors and wireless communication equipment thereby giving waste collection operators access to real-time information on the status of each container. In a previous study (Johansson, 2006)

The chapter focuses on the notion of critical evaluation of information, which is an important part of media and information literacy (MIL). The concepts frictions of relevance and infrastructural meaningmaking are introduced to shed light on the information infrastructure’s significance for MIL in today’s digital media ecology. Furthermore, the chapter discusses some of the limitations inherent i

This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: To assess whether continuous glucose monitoring (CGM) versus any intermittent monitoring modalities to measure glycemia improves neurodevelopmental outcomes in preterm newborn infants.

We study authentic leadership as a prominent but problematic example of positive leadership that we use as a more general “warning” against the current fashion of excessive positivity in leadership studies. Without trying to cover “everything”, we critically examine the principal tenets of mainstream authentic leadership theory and reveal a number of fundamental flaws: shaky philosophical and theo

Conodonts are a clade of chordates and are valuable indicator fossils for biostratigraphy. The segminiplanate (neogondolelliform) conodonts represent a major morphological group ranging from upper Carboniferous to Upper Triassic marine sediments. However, the morphological similarity of segminiplanate P 1 element
