Acute alcohol intoxication impairs segmental body alignment in upright standing.

Balance control when standing upright is a complex process requiring input from several partly independent mechanisms such as coordination, feedback and feedforward control, and adaptation. Acute alcohol intoxication from ethanol is recognized as a major contributor to accidental falls requiring medical care. This study aimed to investigate if intoxication at 0.06 and 0.10% blood alcohol concentra

Being in want of control: Experiences of being on the road to, and making, a suicide attempt.

Attempted suicide is a risk factor for future suicidal behaviour, but understanding suicidality from the perspective of people who have experienced attempted suicide is limited. The aim of the study was to explore the lived experience of being suicidal and having made a suicide attempt, in order to identify possible implications for health care professionals. Semi-structured individual interviews

Applicability Of A Cognitive Model Of Worry To Children And Adolescents

Background: Intolerance of uncertainly (IU), cognitive avoidance (CA) and positive beliefs about worry (PB) independently predict worry frequency in older adolescents and adults, and when targeted together in treatment produce significant reductions in both worry and anxiety in this age range. The present study addresses a gap in the literature by testing whether a cognitive model of excessive wor

Sustainable metal working fluid systems: best and common practices for metal working fluid maintenance and system design in Swedish industry

This paper investigates the function of metal working fluid (MWF) emulsions in automotive industries in Sweden and looks at how the negative environmental and health impact of their use can be reduced through means of monitoring and system design. Major input to this study has been collected from several of the large companies in Sweden, through a literature review, interviews, questionnaires, fin

Menstrual and reproductive factors in women, genetic variation in CYP17A1, and pancreatic cancer risk in the European prospective investigation into cancer and nutrition (EPIC) cohort

Menstrual and reproductive factors and exogenous hormone use have been investigated as pancreatic cancer risk factors in case-control and cohort studies, but results have been inconsistent. We conducted a prospective examination of menstrual and reproductive factors, exogenous hormone use and pancreatic cancer risk (based on 304 cases) in 328,610 women from the EPIC cohort. Then, in a case-control

Artifacts have consequences, not agency: Toward a critical theory of global environmental history

This article challenges the urge within Actor-Network Theory, posthumanism, and the ontological turn in sociology and anthropology to dissolve analytical distinctions between subject and object, society and nature, and human and non-human. It argues that only by acknowledging such distinctions and applying a realist ontology can exploitative and unsustainable global power relations be exposed. The

Assembly of RNA nanostructures on supported lipid bilayers.

The assembly of nucleic acid nanostructures with controlled size and shape has large impact in the fields of nanotechnology, nanomedicine and synthetic biology. The directed arrangement of nano-structures at interfaces is important for many applications. In spite of this, the use of laterally mobile lipid bilayers to control RNA three-dimensional nanostructure formation on surfaces remains largely

The Best Laid Plans: Using the Capability Approach to Assess Neoliberal Conservation in South Africa-The Case of the iSimangaliso Wetland Park

The article documents the case of South Africa's struggle to reconcile racially based poverty, a legacy of apartheid, and attempts to conserve the country's unique and important biodiversity. We present an analysis of KwaDapha, a small village in the iSimangaliso Wetland Park in northern KwaZulu-Natal, a protected area and UNESCO World Heritage Site, in terms of the capability approach. Despite So

Informed Conditioning on Clinical Covariates Increases Power in Case-Control Association Studies

Genetic case-control association studies often include data on clinical covariates, such as body mass index (BMI), smoking status, or age, that may modify the underlying genetic risk of case or control samples. For example, in type 2 diabetes, odds ratios for established variants estimated from low-BMI cases are larger than those estimated from high-BMI cases. An unanswered question is how to use

Association between varus alignment and post-traumatic osteoarthritis after anterior cruciate ligament injury.

PURPOSE: To investigate the association between varus alignment and post-traumatic osteoarthritis (OA) after an anterior cruciate ligament (ACL) injury. METHODS: One hundred subjects with an acute complete ACL tear were followed for 15 years. Anterior-posterior radiographs of the tibiofemoral joint were obtained with a knee flexion of 20°, and the patellofemoral joint was examined with skyline vie

Phenology and its role in carbon dioxide exchange processes in northern peatlands

Ecosystem phenology plays an important role in carbon exchange processes and can be derived from continuous records of carbon dioxide (CO2) exchange data. In this study we examined the potential use of phenological indices for characterizing cumulative annual CO2 exchange in four contrasting northern peatland ecosystems. We used the approach of Jonsson and Eklundh (2004) to derive a set of phenolo

Convective heat transfer and fluid flow physics in some ribbed ducts using liquid crystal thermography and PIV measuring techniques

Enhancement of forced convection is important in several engineering applications. Surface modifications like rib-roughening are commonly used in applications such as compact heat exchangers and internal cooling of gas turbine blades and vanes. This paper gives a brief summary of convective heat transfer and fluid flow in some ribbed ducts using liquid crystal thermography and PIV measuring techni

An optical system for measuring nitric oxide using spectral separation techniques

An optical sensor based on differential absorption spectroscopy for real-time monitoring of industrial nitric oxide (NO) gas emission is described. The influence of gas absorption interference from sulfur dioxide (SO2) in the environment was considered and a spectral separation technique was developed in order to eliminate this interference effect. The absorption spectrum of SO2 around 226 nm was
