Investigation of hydrogen content and dilution effect on syngas/air premixed turbulent flame using OH planar laser-induced fluorescence

Syngas produced by gasification, which contains a high hydrogen content, has significant potential. The variation in the hydrogen content and dilution combustion are effective means to improve the steady combustion of syngas and reduce NOx emissions. OH planar laser-induced fluorescence technology (OH-PLIF) was applied in the present investigation of the turbulence of a premixed flame of syngas wi

Range of hip abduction after preventive and reconstructive surgery in cerebral palsy : a longitudinal registry study of 307 children

Background and purpose — Hip dislocation in cerebral palsy (CP) is caused by altered muscle forces on the joint during typical hip positioning in adduction–flexion–inward rotation. Preventive surgery includes adductor–psoas lengthening (APL) or varus derotation osteotomy (VDRO) of the proximal femur. We assessed the changes in the hip abduction range after these operations. Patients and methods —

Estimation of the effective doses from typical fluoroscopic examinations with barium contrast

The current study aimed to estimate the effective doses and conversion coefficients (CCs) for typical barium swallow (BS), barium meal (BM) and barium enema (BE) protocols and to evaluate the impact of different examination parameters on the resulting CCs. Data were collected in surgical and therapy departments in St. Petersburg Urban Mariinsky Hospital. Computational models were developed using P

20 years after To Err Is Human : A bibliometric analysis of ‘the IOM report's’ impact on research on patient safety

Modern safety science owes much of its current theories and practical approaches to the critical analysis of socio-technological disasters in the nuclear, chemical, maritime, and aviation industries at the end of the 1970 s and in the 1980 s. The medical field by contrast, was not challenged by a single high profile event, but by the release of a single report by the Institute of Medicine in 1999:

Elevated circulating follistatin associates with an increased risk of type 2 diabetes

The hepatokine follistatin is elevated in patients with type 2 diabetes (T2D) and promotes hyperglycemia in mice. Here we explore the relationship of plasma follistatin levels with incident T2D and mechanisms involved. Adjusted hazard ratio (HR) per standard deviation (SD) increase in follistatin levels for T2D is 1.24 (CI: 1.04-1.47, p < 0.05) during 19-year follow-up (n = 4060, Sweden); and 1.31

The Entrepreneurial Story and its Implications for Research

Research is not merely report-writing; it also involves elements of storytelling. In this essay, we reflect on two narrative archetypes in entrepreneurship research: the stories of entrepre- neurship as a road to salvation and means to emancipation. We outline a framework to analyze research from a storytelling perspective, apply this framework to identify implicit assumptions and methodological b

Association of comprehensive mental health with incident cardiovascular disease : A prospective cohort study

BACKGROUND: Evidence is limited regarding the impact of comprehensive mental health on the risk of subsequent cardiovascular events.OBJECTIVES: To investigate the association of mental health status with cardiovascular disease (CVD) in the UK Biobank.METHODS: This prospective study included 339,616 participants aged 40 to 69 years who were enrolled between 2006 and 2010 and were followed up to 202

Impact of the Covid-19 pandemic on primary care utilization : evidence from Sweden using national register data

OBJECTIVE: To analyze changes in primary care utilization as a result of the Covid-19 pandemic. Swedish national register data from 2019 to 2020 on utilization of services were used to compare overall utilization levels and across types of contacts and patient groups. A specific objective was to assess the extent to which remote types of patient consultations were able to compensate for any observ

Single Nucleotide Polymorphisms in Close Proximity to the Fibroblast Growth Factor 21 (FGF21) Gene Found to Be Associated with Sugar Intake in a Swedish Population

Hereditary mechanisms are partially responsible for individual differences in sensitivity to and the preference for sweet taste. The primary aim of this study was to examine the associations between 10 genetic variants and the intake of total sugar, added sugar, and sugars with sweet taste (i.e., monosaccharides and sucrose) in a middle-aged Swedish population. Two single nucleotide polymorphisms

Comparison of organ absorbed doses in whole-body computed tomography scans of paediatric and adult patient models estimated by different methods

This study aimed to identify the uncertainty in estimations of organ absorbed dose using dedicated software by comparing with corresponding doses measured in physical phantoms. The comparison was performed for whole-body computed tomography (CT) obtained as part of positron emission tomography. Whole-body CT scans provide an advantage in terms of comparison because all organs are in the primary be

X-Ray and molecular imaging during pregnancy and breastfeeding - When should we be worried?

Some of the ethically most sensitive issues in radiation protection arise at imaging of pregnant - and potentially pregnant - patients and of newborn. This article reviews the current literature and recommendations on imaging during pregnancy and breastfeeding. Risks related to alternative non-ionizing radiation methods are also considered. With few exceptions, exposure of the fetus through radiog

Development of two-photon polymerised scaffolds for optical interrogation and neurite guidance of human iPSC-derived cortical neuronal networks

Recent progress in the field of human induced pluripotent stem cells (iPSCs) has led to the efficient production of human neuronal cell models for in vitro study. This has the potential to enable the understanding of live human cellular and network function which is otherwise not possible. However, a major challenge is the generation of reproducible neural networks together with the ability to int

Quantification of pulmonary pathology in cystic fibrosis-comparison between digital chest tomosynthesis and computed tomography

Purpose: Digital tomosynthesis (DTS) is currently undergoing validation for potential clinical implications. The aim of this study was to investigate the potential for DTS as a low-dose alternative to computed tomography (CT) in imaging of pulmonary pathology in patients with cystic fibrosis (CF). Methods: DTS and CT were performed as part of the routine triannual follow-up in 31 CF patients. Exte

The Study of Security Priming on Avoidant Attentional Biases : Combining Microsaccadic Eye-Movement Measurement With a Dot-Probe Task

Microsaccades are small fixational eye movements that have shown to index covert attentional shifts. The present experiment combined microsaccades with performance measures from a dot-probe task to study influences of attachment security priming on the attentional biases of individuals high in attachment avoidance. Security priming is an experimental manipulation aimed at boosting felt security. U

The Influence of Level of Education on Instrumental Activities of Daily Living in Patients with Alzheimer’s Disease.

Background: According to the “brain-reserve hypothesis” in Alzheimer’s disease (AD), patients with more years of education are expected to have higher cognitive status during adulthood. Hence, they might have a relatively larger burden of AD pathology and a more advanced level of the disease when dementia is clinically evident. Higher educated people would also be expected to perform better on sta

Testing the psychometric properties of the Swedish version of the EPOCH measure of adolescent well-being

The EPOCH Measure of Adolescent Well-being measures five positive indicators of the well-being of adolescents: engagement, perseverance, optimism, connectedness and happiness. This five-factor structure along with other indicators of validity and reliability were supported for the original English version and the Chinese version. In this study, we tested the psychometric properties of the Swedish
