In the fast development of advanced gas turbines with increasing output power, the inlet temperature is accordingly increased. Traditional cooling techniques failed to deal with such situations; however, new cooling techniques incorporating ribbed microchannels with higher capability of heat removal are required. In the present research, a square ribbed channel with various rib pitch ratios is des
The ability to inhibit unproductive motor responses triggered by salient stimuli is a fundamental inhibitory skill. Such motor self-regulation is thought to underlie more complex cognitive mechanisms, like self- control. Recently, a large-scale study, comparing 36 species, found that absolute brain size best predicted competence in motor inhibition, with great apes as the best performers. This was
A pocket cavity is generated at the connection of two parts, such as the transition part between the low pressure turbine (LPT) and outlet guide vane (OGV) in a gas turbine engine. A bluff body, working as a heat transfer enhancement part or supporting strength part, has tremendous engineering applications in turbomachinery. In the present work, the effect of the pocket on the heat transfer of end
Brain glutamine synthetase (GS) is an integral part of the glutamate-glutamine cycle and occurs in the glial compartment. In vivo Magnetic Resonance Spectroscopy (MRS) allows noninvasive measurements of the concentrations and synthesis rates of metabolites. (15)N MRS is an alternative approach to (13)C MRS. Incorporation of labeled (15)N from ammonia in cerebral glutamine allows to measure several
American political theorist Robert Dahl's 1961 work of political theory exhibits deep levels of creative thinking. When Dahl wrote, the American system of liberal democracy was generally considered to be shaped by a small group of powerful individuals who dominate because they are wealthy and influential. But by connecting the evidence in a new way in Who Governs? Dahl argued convincingly against
Punctuality in Sweden has been too low for several years, and there is now a goal in the industry that it must improve by more than five percentage points by 2020. Research has shown that timetable properties affect punctuality, and timetables can be changed relatively quickly and easily, compared to infrastructure and rolling stock. In this paper we study some strategies for assigning margins in
Interest in learning in mature adulthood has become increasingly important as attention has been focused on what is seen to be an impending crisis in the near future, i.e., shortage of labour due to the ever-growing number of elderly and decreasing nativity rates. In some circles "alarmist demographics" have overshadowed an arguably more important concern, that of providing for aging individuals'
Popular Abstract in Swedish Inom området datorgrafik undersöker man hur virtuella scener kan omvandlas till verklighetstrogna bilder. För interaktiva miljöer, som exempelvis datorspel, måste en ny bild vara genererad och klar att visas på skärmen mellan 30-60 gånger i sekunden för att upplevelsen ska kännas responsiv och för att rörelser ska flyta på ett naturligt sätt. För att datorn ska hinna meThe field of computer graphics refers to the use of computers to generate realistic-looking images from virtual scenes. Graphics processing units use an algorithm known as rasterization to compute images of scenes viewed from a virtual camera. The commonly used pinhole camera model does not account for the imperfections that stem from the physical limitations in real-world cameras. This includes,
A number of policy instruments are used in order to provide consumers healthy products produced in a proper way as regards environmental impacts. The policy instruments are mainly directed to enterprises and companies producing products. Such actors are often addressed in terms of laws or regulations and represents different actors in a production chain. Policy instruments and the way they are use
Objective To determine the relative risks of prostate cancer incidence, metastasis, and mortality associated with screening by serum prostate specific antigen (PSA) levels at age 60. Design Population based cohort study. Setting General male population of Sweden taking part in a screening trial in Gothenburg or participating in a cardiovascular study, the Malmo Preventive Project. Participants The
AIM: This study aimed to evaluate the concomitant occurrence and possible association of breath-holding spells (BHS) and transient erythroblastopenia of childhood (TEC).METHODS: This population-based cohort study, carried out in Southern Sweden from 2004-2014, included patients with BHS and, or, anaemia, including TEC. The subjects were evaluated for the presence of all three conditions and the di
The glycocalyx is a carbohydrate-rich layer that lines the luminal side of the vascular endothelium. Its soluble components exist in a dynamic equilibrium with the bloodstream and play an important role in maintaining endothelial layer integrity. However, the glycocalyx can be easily damaged and is extremely vulnerable to insults from a variety of sources, including inflammation, trauma, haemorrha
Introduction: Few studies have investigated overall satisfaction with prostheses fabricated using low-cost technology. Evidence-based recommendations for prosthetic and orthotic services in low-income countries are needed in order to more effectively provide services. Detailed analysis of variables which influence patient satisfaction with assistive devices are therefore of interest to investigate
This study discusses subordination in Swedish from the perspective of three construction types that involve clauses that have traditionally been difficult to classify as unambiguous main or subordinate clauses: “embedded V2”-constructions, direct speech constructions, and exclamatives. A general hypothesis regarding subordination and "superordination” is proposed: The Highest Force Hypothesis. The
In modern Swedish, the word typ has a number of functions and meanings. Until about 1930, typ had, however, only a nominal function, and the other uses of typ have accordingly developed successively during the 20th century. In this article, which is based on a paper by Skärlund (2010), we track the grammaticalization of typ by utilizing electronic corpora, mainly comprising Swedish newspaper texts

The dynamical theory of X-ray spectra due to Nozieres and De Dominicis (ND, 1969) is evaluated here numerically for numerous model systems including cases where the core-hole potential possesses a bound state. It is shown that the resulting emission spectra obey the final-state rule rather accurately. An approximate but analytical derivation of this rule is given which provides insight into the me
Elevated concentrations of arsenic in drinking water are common worldwide, however, little is known about the presence of other potentially toxic elements. We analyzed 31 different elements in drinking water collected in San Antonio de los Cobres and five surrounding Andean villages in Argentina, and in urine of the inhabitants, using ICP-MS. Besides confirmation of elevated arsenic concentrations
Ischemic stroke affecting the adult brain causes increased progenitor proliferation in the subventricular zone (SVZ) and generation of neuroblasts, which migrate into the damaged striatum and differentiate to mature neurons. Meteorin (METRN), a newly discovered neurotrophic factor, is highly expressed in neural progenitor cells and immature neurons during development, suggesting that it may be inv
