The determination of temperature distribution is an essential task when flames are characterized. We propose a new approach for flame thermometry based on laser-induced breakdown spectroscopy (LIBS) utilizing the temperature dependency of the breakdown threshold laser pulse energy. Calibration measurements are carried out in heated gas flows and post-combustion gases. Compositional effects on the
Photoelectron-Auger electron coincidence spectroscopy is a powerful tool for the investigation of Auger decay processes with different core-ionized intermediate states. In this paper we describe an investigation into the Auger decay of the O-2 molecule, with the purpose of bringing new insight into the dynamics of the core hole decay mechanism. Using a novel experimental approach to measuring such
This study aims to determine the potential origin of Olea pollen recorded in Badajoz in the Southwest of the Iberian Peninsula during 2009-2011. This was achieved using a combination of daily average and diurnal (hourly) airborne Olea pollen counts recorded at Badajoz (south-western Spain) and A parts per thousand vora (south-eastern Portugal), an inventory of olive groves in the studied area and
The principle of force feedback is to design a sensor as a feedback system where the action of the measured variable is compensated by a force generated by feedback. Force feedback has contributed significantly to improve the quality of sensors. A characteristic feature of MEMS devices is that they are subject to random disturbances, such as Brownian motion, Johnson-Nyquist noise, and tunneling no
Signalling through gap junctions contributes to control insulin secretion and, thus, blood glucose levels. Gap junctions of the insulin-producing β-cells are made of connexin 36 (Cx36), which is encoded by the GJD2 gene. Cx36-null mice feature alterations mimicking those observed in type 2 diabetes (T2D). GJD2 is also expressed in neurons, which share a number of common features with pancreatic β-
Recent studies based on self-assessed data on exposure and outcome suggest a negative association between poor health before neck injury and recovery. Our aim was to study actual healthcare consultation and work disability before and after neck injury (whiplash).
The overall aim of this work was to evaluate symptoms, subjectively scored function and physical outcome in patients with surgically treated ankle fractures. Another aim was also to evaluate the effects of a standardised but individually suited supervised training program. In all, 209 patients with surgically treated ankle fractures were included in three different samples: 54 individuals aged 18-
Popular Abstract in English Type 2 diabetes (T2D) is a polygenic disorder characterized by impaired insulin secretion or insulin action in which genes interact with the environment to cause the disease. T2D represent 90% of all patients with diabetes. The disease is increasing globally, with an estimated prevalence of 592 million affected by 2035. According to World Health Organization records, apType 2 diabetes (T2D) is a polygenic disease caused by an interaction between genetic and environmental factors such as low physical activity, smoking, and obesity. The disease is associated with devastating chronic microvascular (nephropathy, retinopathy, and neuropathy) and macrovascular (coronary heart disease and stroke) complications. Genome-wide associated studies (GWASs) have been an unbias
Utifrån ett kulturanalytiskt perspektiv undersöker artikeln på vilket sätt ordet andetag används i språket och på vilka sätt det är kopplat till den kroppsliga upplevelsen av att andas. Metaforiskt används ordet andetag synonymt med liv i det svenska språket. Härigenom synliggör ordet de kulturella klassifikationer som finns mellan liv och död. Andetaget är också en del av en kroppslig situation d
The timing of the ice margin retreat of the Late Glacial Patagonian Ice Sheet (PIS) in southern Patagonia has been the object of discussion for many years. In order to resolve questions about the complex response of the PIS to past climate change, any geological interpretation and data modelling need evaluation against an absolute chronology. The aim of this project is to investigate the applicabi
Resistance towards endocrine therapy is a great concern in breast cancer treatment and may partly be explained by the activation of compensatory signaling pathways. The aim of the present study was to investigate if the insulin-like growth factor-1 receptor (IGF1R) signaling pathway was activated or deregulated in breast cancer patients and to explore if any of the markers were prognostic, with or
Neuroblastoma is a childhood malignancy of the sympathetic neuronal lineage. It is a rare disease, but since it is frequently diagnosed during infancy, neuroblastoma causes life-long medical follow up of those children that survive the disease. It was early recognized that a high tumor cell differentiation stage correlates to favorable clinical stage and positive clinical outcome. Today, highly di
The objective of the current study is to investigate the clarification of two high-added value products (pectin containing solution and phenol containing beverage) recovered from olive mill wastewater. For this purpose, both liquids were processed with four types of ultrafiltration (100, 25, 10 and 2 kDa) and one nanofiltration membranes under optimum transmembrane pressure. Retention coefficients
Background: Bronchial smooth muscle cells (BSMCs) from severe asthmatics have been shown to overexpress the Th2-driving and asthma-associated cytokine IL-33. However, little is known regarding factors involved in BSMC production of IL-33. Rhinovirus (RV) infections cause asthma exacerbations, which exhibit features of Th2-type inflammation. Here, we investigated the effects of epithelial-derived m
Few previous publications investigate the possibility of combining multiple waste heat sources in a combustion engine waste heat recovery system. A waste heat recovery system for a HD truck diesel engine is evaluated for utilizing multiple heat sources found in a conventional HD diesel engine. In this type of engine more than 50% of heat energy goes futile. The majority of the heat energy is lost
The modern business environment requires managers to make effective decisions in a dynamic and uncertain world. How can such dynamic decision making (DDM) improve? The current study investigated the effects of brief training aimed at improving DDM skills in a virtual DDM task. The training addressed the DDM process, stressed the importance of self-reflection in DDM, and provided 3 self-reflective
