Airborne and Dermal Exposure to Polycyclic Aromatic Hydrocarbons, Volatile Organic Compounds, and Particles among Firefighters and Police Investigators

AIMS: The main aim of this study was to assess dermal exposure to polycyclic aromatic hydrocarbons (PAHs) and airway exposure to PAHs, volatile organic compounds (VOCs; benzene and 1,3-butadiene), and particles among firefighters (FFs) and police forensic investigators (PFIs) in Sweden. METHODS: Active (pump with a filter and sorbent tube) and passive (polyurethane foam -cyl and perkin elmer carbo

Sunset integrals at finite volume

Chiral Perturbation Theory is a useful tool to aid in performing the various extrapolations needed in lattice QCD calculations of physical quantities. These include extrapolations in quark mass, finite lattice spacing and finite size of the lattice. Especially the latter will becomemore important when the quark masses on the lattice become smaller. Here we develop the needed two-loop integrals at

Status of Strong ChPT

The present status of Chiral Perturbation Theory (ChPT) in the strong mesonic sector is discussed. A very short introduction to ChPT is followed by an overview of existing two-loop calculations and the determination of the Low-Energy-Constants (LECs). I discuss the case of $\eta\to\pi\pi\pi$ decays in somewhat more detail and finish by mentioning some recent work on partially quenched ChPT and on

Carbon dynamics, net primary productivity and human-appropriated net primary productivity across a forest–cocoa farm landscape in West Africa

Terrestrial net primary productivity (NPP) is an important metric of ecosystem functioning; however, there are little empirical data on the NPP of human-modified ecosystems, particularly smallholder, perennial crops like cocoa (Theobroma cacao), which are extensive across the tropics. Human-appropriated NPP (HANPP) is a measure of the proportion of a natural system's NPP that has either been reduc

Centennial-long trends of lake browning show major effect of afforestation

Observations of increasing water color and organic carbon concentrations in lakes are widespread across the Northern Hemisphere. The drivers of these trends are debated. Declining atmospheric sulfur deposition has been put forward as an important underlying factor, since recovery from acidification enhances mobility of organic matter from surrounding soils. This would suggest that the current brow

Bacterial pseudokinase catalyzes protein polyglutamylation to inhibit the SidE-family ubiquitin ligases

Enzymes with a protein kinase fold transfer phosphate from adenosine 5'-triphosphate (ATP) to substrates in a process known as phosphorylation. Here, we show that the Legionella meta-effector SidJ adopts a protein kinase fold, yet unexpectedly catalyzes protein polyglutamylation. SidJ is activated by host-cell calmodulin to polyglutamylate the SidE family of ubiquitin (Ub) ligases. Crystal structu

Highly Strained III-V-V Coaxial Nanowire Quantum Wells with Strong Carrier Confinement

Coaxial quantum wells (QWs) are ideal candidates for nanowire (NW) lasers, providing strong carrier confinement and allowing close matching of the cavity mode and gain medium. We report a detailed structural and optical study and the observation of lasing for a mixed group-V GaAsP NW with GaAs QWs. This system offers a number of potential advantages in comparison to previously studied common group

Biological treatment of ankylosing spondylitis : A nationwide study of treatment trajectories on a patient level in clinical practice

Background: There is substantial evidence that patients with ankylosing spondylitis (AS) have high response rates to tumour necrosis factor inhibitors (TNFi), a low likelihood of successful treatment termination, but yet a limited drug retention. Whereas several reports have assessed drug retention rates for TNFi in AS, there are few, if any, studies investigating the actual treatment trajectories

Positive psychological well-being predicts lower severe pain in the general population : A 2-year follow-up study of the SwePain cohort

Background: Positive psychology indicators like well-being and life satisfaction may play a pivotal role in pain-related outcomes. In this study, we aimed to examine the prospective associations of positive well-being and life satisfaction with pain severity. Methods and Subjects: This longitudinal study, with a follow-up of 2 years, included 9361 participants (4266 males, 5095 females; mean age:

Recommendations for Core Outcome Domain Set for Whiplash Associated Disorders (CATWAD)

Objective: Inconsistent reporting of outcomes in clinical trials of treatments for Whiplash Associated Disorders (WAD) hinders effective data pooling and conclusions that can be drawn about the effectiveness of tested treatments. The aim of this study was to provide recommendations for core outcome domains that should be included in clinical trials of WAD. Methods: A three-step process was used. 1

The benefits of collaboration : The Nordic Arthroplasty Register Association

□ The Nordic Arthroplasty Register Association (NARA) was established in 2007 by arthroplasty register representatives from Sweden, Norway and Denmark with the overall aim to improve the quality of research and thereby enhance the possibility for quality improvement with arthroplasty surgery. Finland joined the NARA collaboration in 2010. □ NARA minimal hip, knee and shoulder datasets were created

Dialogue with property owners and property developers as a tool for sustainable transformation : A literature review

The housing sector is important for achieving ambitious environmental targets. In the European Union, buildings account for 40% of energy consumption and 36% of CO2 emissions. Considering the scale of the housing sector's environmental impact, interventions in how new housing is built and existing housing is renovated have great potential for sustainable transformation. However, the sector has not

Fracture of laminated bamboo and the influence of preservative treatments

Treated bamboo can be made into large, durable structural elements which have the potential to become a transformative large-scale building material, but the fracture behaviour which determines their ultimate strength in various loading scenarios has not been studied. Laminated bamboo is a promising structural engineered bamboo material, and is generally made from bamboo treated to improve its dur

Den svenska supply chain-panelen : Supply Chain Risk Management

Den sjätte studien är fokuserad på Supply chain risk management (SCRM), d.v.s. vi försöker förstå hur företag identifierar, analyserar och hanterar risker i sin försörjningskedja. Det gäller både i Risk Management i interna logistikflöden (egna lager, egna fabriker, transporter mellan egna anläggningar etc) men framför allt Supply Chain Risk Management i externa försörjningskedjor (leverantörer, u

Manganese transporter genetics and sex modify the association between environmental manganese exposure and neurobehavioral outcomes in children

There is increasing evidence that environmental manganese (Mn) exposure early in life can have negative effects on children's neurodevelopment and increase the risk of behavioral problems, including attention deficit hyperactivity disorder (ADHD). Factors that may contribute to differences in sensitivity to Mn exposure are sex and genetic variation of proteins involved in the regulation of Mn conc

User involvement in housing recovery after typhoon Haiyan from a capability perspective

Typhoon Haiyan hit the Philippines on 8th November 2013 destroying more than 1 million houses and affecting mostly the poor. This paper discusses user involvement in housing recovery from a capability perspective. The paper also analyses possibilities for extension of the housing solutions. Based on the Sphere handbook and the theoretical framework, a Model for user involvement in evolutionary hou
