The effect of hydrogen enrichment to natural gas flames was experimentally investigated at atmospheric pressure conditions using flame chemiluminescence imaging, planar laser-induced fluorescence of hydroxyl radicals (OH PLIF), and dynamic pressure monitoring. The experiments were performed using a third generation dry low emission (DLE) burner used in both SGT-700 and SGT-800 industrial gas turbi

This study aimed to find out how the insulation of the footwear changes over one week of use. A thermal foot model with 8 measuring zones and 5 “sweat glands” was used for tests. A thin sock was donned on the model to allow better water distribution all over the foot surface. Four boots were tested over a period of 5 days. Each day was divided into 9 hour measurement period and 15 hour conditionin

Popular Abstract in Swedish Många djur och växter har någon form av permanent försvar mot angrepp, t ex taggar och utskott. Andra försvarar sig inte alls utan satsar istället på att föröka sig så fort som möjligt. Den kanske mest sofistikerade strategin har de djur och växter som väljer att försvara sig enbart vid behov, s k predator-inducerade försvar. Predator-inducerade försvar är särskilt intrIn this thesis, I have investigated factors (cues, benefits, and costs) affecting the evolution of an inducible morphological defence in crucian carp (Carassius carassius). Inducible defences are favoured over permanent defences when prey have reliable cues to detect predators, when defences are effective but costly, and when predation pressure is variable and unpredictable, but sometimes s

The paper presents main conceptual distinctions underlying much of modern philosophical thinking about value. The introductory Section 1 is followed in Section 2 by an outline of the contrast between non-relational value (impersonal good, or good, period) and relational value (good for someone, or—more generally—good for some entity). In Section 3, the focus is on the distinction between final and

Designs for Extremely Large Telescopes (ELTs) are quite well advanced,but the requirements of instruments have had limited impact. Sinceprovision of a suitable environment for instruments is a critical aspectof all telescopes, we outline some well-known and some less-appreciatedchallenges of designing instruments for ELTs. A wide-field spectrometer(WFSPEC) with ~10 arcmin field-of-view, probably w

Finger tapping to isochronous pacing stimuli is a well established experimental paradigm first described in the late 19th century. Two variables of common interest in rhythmic tapping tasks are timing variability and constant error. However, a difficulty when estimating these variables is that at interstimulus intervals longer than 2 seconds participants regularly overshoot the target interval and

In 1975 Mozambique attained its independence from Portugal, but it was only in 1992 with the establishment of a peace agreement after the extended civil war that the country was able to initiate its development process including the undertaking of research and development (R & D) efforts. Government and international cooperation provided the support for the R & D programmes and projects, m

Within a course in academic writing, first-term students of English currently construct individualized study-plans detailing both what they should do during the term and when they should do it. Students calculate the average workload for all their courses, and include in their study-plans all the hours they should spend both in and outside the classroom on each course, totalling in 40-hour working

Husserlian phenomenological theory is offered as an integrated and integrating for an understanding of management decision making and related issues in work and organizational sciences. The aspects of meaning, meaning constitution, subjective processes, and perspectives, mutual understanding of each other´s perspective, individuals as horizons of possible worlds are central to this conception, mak

This article presents the developments of an ongoing research aimed at modelling the influence of fissuring on the behaviour of clays. In particular, it recalls the main results of an extensive laboratory investigation on a fissured bentonite clay from the south of Italy and presents the data of a new investigation on the evolution with shearing of the strain fields developing within the clay, res
