Relict spinel grains (similar to 25-250 mu m in diameter) from decomposed extraterrestrial material in Archean to Recent sediments can be used to reconstruct variations in the flux of different types of meteorites to Earth through the ages. Meteorite falls are rare and meteorites weather and decay rapidly on the Earth surface, making it a challenge to reconstruct ancient fluxes. Almost all meteori

III–V nanowire (NW) transistors are an emerging technology with the prospect of high performance and low power dissipation. Performance evaluations of these devices, however, have focused mostly on the intrinsic properties of the NW, excluding any parasitic elements. In this paper, a III–V NW transistor architecture is investigated, based on a NW array with a realistic footprint. Based on scaling

Measuring pilot mental workload can be important for understanding cognitive demands during flight involving unusual movements and attitudes. Data on heart rate, eye movements, EEG, and subjective ratings from 7 flight instructors were collected for a flight including a repeated aerobatics sequence. Heart rate data and subjective ratings showed that aerobatic sequences produced the highest levels

In magnetic resonance imaging (MRI), the balanced steadystate free precession (bSSFP) pulse sequence has shown to be of great interest, due to its relatively high signal-to-noise ratio in a short scan time. However, images acquired with this pulse sequence suffer from banding artifacts due to offresonance effects. These artifacts typically appear as black bands covering parts of the image and they

Abstract in Danish Hvad er det der ‘kvæær’ egentlig? Dette spørgsmål synes altid at klistre til tekster og praksisser med queer som udgangspunkt, og dets svar bliver ofte tøvende, hængende i luften – ambivalent, utydeligt og afhængig af kontekst. For den som stiller spørgsmålet, bliver svaret næsten aldrig så konkret som hen håbede på. Og for den som forventes at svare, bliver diffuse henvisninger

As a global society we are entering an era where land areas and land-based resources are coming to the fore once again for capital accumulation and economic growth, for the first time since the end of the 18th century when Malthus forecasted a contradiction between population growth and agricultural output. That constraint on economic growth, imposed by limited land areas, was overcome by the comb

Background: Musculoskeletal disorders (MSDs) are a major reason for impaired work productivity and sick leave. In 2009, a national rehabilitation program was introduced in Sweden to promote work ability, and patients with MSDs were offered multimodal rehabilitation. The aim of this study was to analyse the effect of this program on health related quality of life, function, sick leave and work abil

Since knowability must emanate from the single individual, singularity constitutes the frame of reference, and the embodiment of knowing is expected to emerge through individual text production. Furthermore, the basis of the presented studies will consist of text materials with unknown frame factors. This is especially underlined by the fact that history at the Times of Tacitus was an art, not a s

The Swedish botanist, Darwinist, socialist, and atheist Bengt Lidforss (1868–1913) passed away one hundred years ago, on September 23, 1913. His research was mainly focused on plant physiology, and the problem of speciation within the genus Rubus (blackberries) in particular came to follow him as a constant mystery. Besides his work as a teacher, researcher, and finally professor of botany at Lund

Serotonin, a highly pro-inflammatory molecule released by activated platelets, is formed by tryptophan. Tryptophan is also needed in the production of kynurenine, a process mediated by the type I interferon (IFN)-regulated rate-limiting enzyme indoleamine 2,3-dioxygenase (IDO). The aim of this study was to investigate levels of serotonin in patients with the autoimmune disease systemic lupus eryth

In March 2011 the Supreme Court issued its Prometheus opinion and granted certiorari, and reversed and remanded Myriad I for consideration in light of Prometheus. In August 2012 the Myriad II decision was issued. The panel in Myriad II repeated most of their separate Myriad I opinions. Myriad deja vu looked much like Myriad I with panel members agreeing that Prometheus did not control the composit

Background and purpose The Charnley Elite-Plus stem was introduced in 1993 as a presumed improvement of the flanged Charnley stem. We started this study in 1996 to investigate the migratory pattern of the Elite-Plus stem. Patients and methods We followed 114 patients with osteoarthritis and a primary total hip replacement with the Elite-Plus stem. Mean age at the time of operation was 64 (50-76) y

Popular Abstract in Swedish Inom forskningsområdet biogeokemi studerar man hur naturens olika grundämnen, såsom kol, kväve, fosfor och kisel ändrar form och transporteras genom landskapet för att via bäckar och vattendrag till slut nå havet. Tillsammans beskriver dessa olika processer, som sker på olika tidsskalor, från sekunder till flera miljoner år, ett grundämnes kretslopp (eller biogeokemiskaSilicon is the next most abundant element in the Earth’s crust and its biogeochemical cycle is linked with that of carbon. Further, silicon is a beneficial nutrient for plants in terrestrial ecosystems and a key nutrient for diatoms in aquatic ecosystems. During the last decade the important role of terrestrial vegetation in controlling Si fluxes downstream aquatic environments, via incorporation

In this study we report on instability phenomena in a solution where shear induces multilamellar vesicles (MLVs) from a lamellar phase. A shear-thickening regime has been observed for hexadecyl tetraethylene glycol ether (C16E4) dissolved in D2O at 40 degrees C. In this regime, unstable temporal viscosity behavior, i.e. periodic oscillations, has been observed at 2, 5 and 10 s(-1). Moreover at a s

Background and objectives Vascular disease is common in systemic lupus erythematosus (SLE) and patients with antiphospholipid antibodies (aPL) are at high risk to develop arterial and venous thrombosis. Since HLA class II genotypes have been linked to the presence of pro-thrombotic aPL, we investigated the relationship between HLA-DRB1 alleles, aPL and vascular events in SLE patients. Methods 665

This paper is a translation of my "Preference Utilitarianism by Way of Preference Change?", in which I revisit Richard Hare’s classical and much discussed argument for preference utilitarianism (Moral Thinking, 1981), which relies on the conception of moral deliberation as a process of thought experimentation, with concomitant preference change. The paper focuses on an apparent gap in Hare’s reaso
