This qualitative case study aims at understanding when and how industrial designers, working in design consultancies, engage in activities that will influence material selection in the design process. While the extant literature presents material selection processes as a sequence of activities aimed at finding candidate materials, there is paucity of research on material criteria activities. Formu
The Agricola has long been a popular object of study for the connection that it makes between the British narrative of resistance against Roman domination and the Roman narrative of resistance against imperial domination. However, no agreement has been reached on the question of how exactly the two narratives 'affect' each other. Simultaneously, while it has often been remarked that Tacitus' langu
In order to improve the surface quality of TC4 titanium alloy parts, the effect of grinding parameters on surface integrity must be known. In this research, an experimental analysis has been conducted to understand the effect of grinding parameters, including cutting velocity, feed rate, grinding depth and abrasive size, on material removal and surface integrity. Before conducting experiment, test
Swirl stabilized premixed flames are common in industrial gas turbines. The flame shape in the combustor is highly related to the combustion stability and the performance of the gas turbine. In the current paper, the effects of confinement on the time averaged flame structures or flame macrostructures are studied experimentally. Experiments are carried out with swirl number S = 0.66 in two cylindr
It is possible to improve the sensitivity of immunoassays by several orders of magnitude by exploiting nanoenvironmental effects. This approach can detect trace amounts of compounds and will better illuminate the presence of signal substances in biological systems. Here we describe a method for ultrasensitive immunoassays using 'normal' antibodies (Abs).
Fresh and aged diesel soot particles have different impacts on climate and human health. Whilefresh diesel soot particles are highly aspherical and non-hygroscopic, aged particles are sphericaland hygroscopic. Aging and its effect on water uptake also controls the dispersion of diesel soot inthe atmosphere. Understanding the timescales on which diesel soot ages in the atmosphere is thus important,Fresh and aged diesel soot particles have different impacts on climate and human health.

Knowledge about the natural history of severe alpha 1-antitrypsin (AAT) deficiency (PiZZ) is limited. Our aim was to compare the survival of PiZZ individuals with randomly selected controls from the Swedish general population. The PiZZ subjects (n=1585) were selected from the Swedish National AATD Register. The controls (n=5999) were randomly selected from the Swedish population register. Smoking
The ESS Linac project, phase I, requires 12 long pulse klystron modulators with compact footprint, high pulse power and improved quality both on the output pulse waveform and on the input AC power line. Conventional long pulse modulators are typically based on HV pulse transformers and commonly exhibit poor efficiency, low power density, large footprint and cost, with still limited performance on
Effects of the bluff-body's position on diffusion flame structures and flame instability characteristics were investigated experimentally. A flame regime diagram together with the corresponding flow fields were proposed to evaluate the influences caused by the alternation of bluff-body's position. The disk shape bluff-body was placed 10 mm downstream or at the same height with the annular channel
Sustainable development remains of general interest in both political and academic circles. Importantly, the approach to collective decision making adopted in pursuit of sustainable development has importance repercussions regarding what range of possible informational considerations get incorporated as relevant to a given choice exercise. The most dominant approach to environmental public policy
In this work, eleven different combinations of work piece materials and tool grades have been evaluated in wear test when turning with cemented carbide insert. The most commonly used tool life models such as the Taylor model, the Extended Taylor model, the Coromant Turning model version 1 and the Colding model have been tested on the data and their accuracy is presented. The well-known Taylor mode
The article is based on my contribution to the Phenomenology and Aesthetics seminar at the University of Riga 29 Jun - 1 July 2017, where I compared Edith Stein's theory about Empathy (Einfühlung) with Stanislavski's conception of scenic action as perspective taking.
Coal has been the main fuel in the generation of heat and power for many years and will continue to be so for years to come. Global warming awareness has led to the Kyoto Protocol, which targets the abatement of six greenhouse gases, including carbon dioxide (CO2). For the abatement of CO2 emissions, co-combustion of coal and biomass is an attractive solution. Other mitigation solutions include ox

Polyvinyl chloride (PVC) is a common thermoplastic whichfinds widespread applications in the construction industry for usage inceiling linings, flooring materials, electrical cables and roofing materials. Several fire requirements are put on these types of applications. For fire safety engineering and product development, thermo-chemical decomposition modeling of PVC isrequired. The FIRETOOLS proj
Background--Atherosclerosis is an inflammatory lipid disorder and the main underlying pathology of acute ischemic events. Despite a vast amount of data from murine atherosclerosis models, evidence of B-cell involvement in human atherosclerotic disease is limited. We therefore investigated the association of circulating B-cell subtypes with the occurrence of secondary cardiovascular events in advan
Dysregulation of gene expression in islets from type 2 diabetic patients might be causally involved in the development of hyperglycemia or it could develop as a consequence of hyperglycemia, i.e. glucotoxicity. To separate the genes potentially causally involved in pathogenesis from those likely to be secondary to the hyperglycemia we exposed islets from human donors to normal or high glucose conc
Gestational diabetes mellitus(GDM) defines an unhealthy state of hyperglycaemia that develops in response to an otherwise normal physiological adaptive insulin resistance state during pregnancy. However, the exact plasma glucose levels differentiating the unhealthy GDM state from a normal pregnancy is unknown, and relies upon arbitrary cut off criteria based on associations with adverse health out
BACKGROUND AND PURPOSE: There are, to date, no MR imaging diagnostic markers for Lewy body dementia. Nigrosome 1, containing dopaminergic cells, in the substantia nigra pars compacta is hyperintense on SWI and has been called the swallow tail sign, disappearing with Parkinson disease. We aimed to study the swallow tail sign and its clinical applicability in Lewy body dementia and hypothesized that
