Comparative Toxicity of Nanoparticulate CuO and ZnO to Soil Bacterial Communities

The increasing industrial application of metal oxide Engineered Nano-Particles (ENPs) is likely to increase their environmental release to soils. While the potential of metal oxide ENPs as environmental toxicants has been shown, lack of suitable control treatments have compromised the power of many previous assessments. We evaluated the ecotoxicity of ENP (nano) forms of Zn and Cu oxides in two di

Hinders for continued work among persons with fibromyalgia

Background: Work disability is common among women with fibromyalgia (FM). The aim of the study was to investigate what health problems and work-related difficulties lead to hinders for continued work among women with FM. Methods: A qualitative interview study. Twenty-seven gainfully employed women with FM participated in five focus group interviews. Their median age was 52 years, ranging from 33 t

Parallel fiber and climbing fiber responses in rat cerebellar cortical neurons in vivo.

Over the last few years we have seen a rapidly increasing interest in the functions of the inhibitory interneurons of the cerebellar cortex. However, we still have very limited knowledge about their physiological properties in vivo. The present study provides the first description of their spontaneous firing properties and their responses to synaptic inputs under non-anesthetized conditions in the

Wave Damping in Reed: Field Measurements and Mathematical Modeling

Wave damping in vegetation in shallow lakes reduces resuspension and thereby improves the light climate and decreases nutrient recycling. In this study, wave transformation in reed (Phragmites australis) was measured in a shallow lake. Theoretical models of wave height decay, based on linear wave theory, and transformation of the probability density function (PDF), using a wave-by-wave approach, w

Calcium-induced mitochondrial permeability transition in CNS-derived mitochondria - Pharmacological aspects of specificity and toxicity in neuroprotection

Mitochondria are the main site for energy conversion in the cell. Under certain circumstances, such as excess calcium retention or production of reactive oxygen species, a pore forms at contact sites between the outer and the normally impermeable inner mitochondrial membrane. The ensuing osmotic mitochondrial swelling and loss of bioenergetic function is referred to as the mitochondrial permeabili

Benefits of Guiding Supplemental Instruction Sessions for SI Leaders: a Case Study for Engineering Education at a Swedish University

In previous studies on Supplemental Instruction (SI) relatively little attention has been paid to the “senior” students who lead the sessions. The focus in this study is on the benefits that the SI leaders gain from their SI experience. Data from one questionnaire directed at 35 students who recently completed their assignment as SI leaders, and another questionnaire directed at 20 former SI leade

Pollen season and climate: Is the timing of birch pollen release in the UK approaching its limit?

In light of heightened interest in the response of pollen phenology to temperature, we investigated recent changes to the onset of Betula (birch) pollen seasons in central and southern England, including a test of predicted advancement of the Betula pollen season for London. We calculated onset of birch pollen seasons using daily airborne pollen data obtained at London, Plymouth and Worcester, det

The Nordic Obstetric Surveillance Study: a study of complete uterine rupture, abnormally invasive placenta, peripartum hysterectomy, and severe blood loss at delivery

Objective: To assess the rates and characteristics of women with complete uterine rupture, abnormally invasive placenta, peripartum hysterectomy, and severe blood loss at delivery in the Nordic countries. Design: Prospective, Nordic collaboration. Setting: The Nordic Obstetric Surveillance Study (NOSS) collected cases of severe obstetric complications in the Nordic countries from April 2009 to Aug

Measurement of exclusive gamma gamma -> l(+)l(-) production in proton-proton collisions at root s=7 TeV with the ATLAS detector

This Letter reports a measurement of the exclusive gamma gamma -> l(+)l(-) (l = e, mu) cross-section in proton-proton collisions at a centre-of-mass energy of 7 TeV by the ATLAS experiment at the LHC, based on an integrated luminosity of 4.6 fb(-1). For the electron or muon pairs satisfying exclusive selection criteria, a fit to the dilepton acoplanarity distribution is used to extract the fiducia

Morphology-Function Relationships and Repeatability in the Sperm of Passer Sparrows

Sperm performance is likely to be an important determinant of male reproductive success, especially when females copulate with multiple males. Understanding sperm performance is therefore crucial to fully understand the evolution of male reproductive strategies. In this study, we examined the repeatability of sperm morphology and motility measures over three breeding seasons, and we studied relati

Control of composition and morphology in InGaAs nanowires grown by metalorganic vapor phase epitaxy

InGaAs nanowires grown by Metalorganic Vapor Phase Epitaxy (MOVPE) are promising candidates in future device technologies. The control of the chemical composition of InGaAs nanowires is not trivial due to the In atom diffusion from the substrate, which causes significant variations in the chemical composition along the nanowire. In this work, we report on the growth of InGaAs nanowires on (111)B I

Suppression of Upsilon(1S) at forward rapidity in Pb-Pb collisions at root s(NN)=2.76 TeV

We report on the measurement of the inclusive Upsilon(1S) production in Pb-Pb collisions at root s(NN) = 2.76 TeV carried out at forward rapidity (2.5 < y < 4) and down to zero transverse momentum using its mu(+)mu(-) decay channel with the ALICE detector at the Large Hadron Collider. Astrong suppression of the inclusive Upsilon(1S) yield is observed with respect to pp collisions scaled by the num

Daily occupations among asylum seekers- Experience, performance and perception

Asylum seekers often find themselves in a situation where the structure and content of daily occupations have been disrupted and they might have limited access to paid work and education. Studies have shown that asylum seekers experience occupational depri- vation and a change in daily occupations which might even influence their identity. Such deprivation can eventually lead to dissatisfaction wi
