An Epidemiological Study of Exhaustion in the Context of Chronic stress. Concept, Cortisol, Causes and Consequences
Popular Abstract in Swedish Intresset för utmattning har ökat både i Sverige och internationellt under de senaste årtiondena. Utmattning som begrepp är oklart definierat vetenskapligt, och det finns olika benämningar på utmattningstillstånd, som till exempel den något gammalmodiga benämningen neurasteni, som ännu finns kvar som diagnos-klassifikation (där även benämnt ”trötthetssyndrom”), kronisktThe interest in exhaustion has increased rapidly during the last few decades in many developed countries. In Sweden, prevalence of exhaustion increased by 50 percent on average between 1989 and 2005, and recent data reveals that exhaustion still remains at this higher level. Scientifically, exhaustion is not clearly defined. Chronic stress is acknowledged to give rise to exhaustion, but specific m
Ventilated Trombe wall as a passive solar heating and cooling retrofitting approach; a low-tech design for off-grid settlements in semi-arid climates
In the coming years, it is anticipated that if we continue with the same pace of energy consumption, communities will continue to face three major challenges; a mounting increase in energy demands, pollution, and global warming. On a local scale, Egypt is experiencing one of its most serious energy crises in decades. The energy consumed in indoor cooling and heating is the biggest portion of total
Production of pions, kaons and protons in pp collisions at root s=900 GeV with ALICE at the LHC
The production of pi(+), pi(-), K+, K-, p, and (p) over bar at mid-rapidity has been measured in proton-proton collisions at root s = 900 GeV with the ALICE detector. Particle identification is performed using the specific energy loss in the inner tracking silicon detector and the time projection chamber. In addition, time-of-flight information is used to identify hadrons at higher momenta. Finall
From A Farm to Cow Chapel: Farming and Forestry in Art
The article is a survey of how farming and forestry is depicted in art in Sweden during the 19th century. The author discusses what is depicted, as well as how and why. A focus question in the article is the relative abscence of farming and forestry as a motif on the Swedish art scene during the period.
A proposal that does not advance our understanding of hypnosis
In his paper Hypnosis Reconsidered, Resituated, and Redefined (JSE 26(2):297–327), Adam Crabtree, a distinguished expert in the history of hypnosis, maintains that contemporary hypnosis research suffers from conceptual disorder. In his words, he attempts to redefi ne hypnosis in order to provide a stronger ground for future research. We find that his proposed reconsideration of hypnosis as a form
Energy availability and the female athlete triad in elite endurance athletes
The female athlete triad (Triad), links low energy availability (EA), with menstrual dysfunction (MD), and impaired bone health. The aims of this study were to examine associations between EA/MD and energy metabolism and the prevalence of Triad-associated conditions in endurance athletes. Forty women [26.2 +/- 5.5 years, body mass index (BMI) 20.6 +/- 2.0 kg/m(2), body fat 20.0 +/- 3.0%], exercisi

Insight into Danube sturgeon life history: trace element assessment in pectoral fin rays
Sturgeon populations in the Danube River have experienced severe decline during the last several decades, mostly due to the poorly regulated fishery, river fragmentation and water pollution. This study focuses on gaining better understanding of sturgeon life history primarily by addressing the assessment of microelement accumulation in sturgeon pectoral fin rays, especially of strontium and calciu
New Insights into the Origins of Sb-Induced Effects on Self-Catalyzed GaAsSb Nanowire Arrays.
Ternary semiconductor nanowire arrays enable scalable fabrication of nano-optoelectronic devices with tunable bandgap. However, the lack of insight into the effects of the incorporation of Vy element results in lack of control on the growth of ternary III-V1-yVy nanowires and hinders the development of high-performance nanowire devices based on such ternaries. Here, we report on the origins of Sb-
A MIMO channel model for wireless personal area networks
Recent years have seen an increasing attention given to wireless Personal Area Networks (PANs), which are typically networks with small transmitter-receiver (TX-RX) separation. The desire for high data rates has led to an interest in deploying multiple-input multiple-output (MIMO) transmission for such systems, but up until this date there exists, to the authors’ best knowledge, no MIMO channel mo
Noncollinear optical gating
We present a novel scheme for high-order harmonic generation, enabling the production of spatially separated isolated attosecond pulses. This can be achieved by driving the generation process with two identical, but temporally delayed laser pulses, which are noncollinearly overlapping in the generation medium. Our approach provides intense attosecond pulses directly separated from the fundamental
The Swedis Ne Bis in Idem Saga - Painting a multi-layered picture
The primary aim of the article is to examine the sum of the three Swedish judgments of 2013 that was handed down after the ECJ's judgment in the Åkerberg Fransson-case. The examination is done against the backdrop of the legal developments preceding these judgments, with a particular attention to how different layers of law are perceived and given effect in the national legal order.
Environmental assessment and scenario analysis of sugar beet transport in Scania, Sweden
The aim was to assess the environmental sustainability of sugar beet transport in Scania, Sweden—estimating lorry travel distances, fuel use and air emissions. Scenario analyses measuring the same parameters for switching to newer vehicle types and differing ratios of biodiesel were also performed. The method applied for distance calculations was a GIS-based proximity analysis. Results revealed th
Growth of mature boreal Norway spruce was not affected by elevated [CO2] and/or air temperature unless nutrient availability was improved
Digital Materialities and Family Practices : The Gendered, Practical, Aesthetical and Technological Domestication of Play
Digital gameplay is now firmly embedded in everyday practices in many Scandinavian homes. This paper deals with the constitution of such practices in families by taking a closer look at the material objects essential to play and their role in the “design of everyday life” (Shove et al 2007). It uses ethnographic method and anthropological practice theory to attend to the domestic spaces of leisure
Numerical Simulation of Unsteady Flows of Physiological Relevance
Pulsatile flows in geometries of physiological relevance have been investigated. Atherosclerotic plaques are (initiated) near junctions and bifurcations in larger arteries. The flow in these regions is characterized by flow separation and unsteadiness, which indicates that local flow conditions contribute to atherogenesis. Flows in curved and bifurcating pipes have been investigated over many y
The Effects of Innovativeness on Effectiveness and Efficiency
Purpose – Whilst researchers have explored the relationship between innovativeness and business performance in different organizations, such studies in services such as restaurants are scarce. The purpose of this paper is to examine potential influences of innovativeness on effectiveness and efficiency and their subsequent effects on restaurant business performance. Design/methodology/approach –
Waveform Characterization of Atrial Fibrillation Using Phase Information
A novel method for characterization of f-wave morphology in atrial fibrillation (AF) is presented. The method decomposes atrial activity into fundamental and harmonic components, dividing each component into short blocks for which the amplitudes, frequencies, and phases are estimated. The phase delays between the fundamental and each of the harmonics, here referred to as harmonic phase relationshi
Blueberry husks, rye bran and multi-strain probiotics affect the severity of colitis induced by dextran sulphate sodium
Objective. The enteric microbiota is a pivotal factor in the development of intestinal inflammation in humans but probiotics, dietary fibres and phytochemicals can have anti-inflammatory effects. The aim of this study was to evaluate the therapeutic effect of multi-strain probiotics and two conceivable prebiotics in an experimental colitis model. Material and methods. Sprague-Dawley rats were fed
