We have developed and characterized a hard x-ray accumulating streak camera that achieves subpicosecond time resolution by using single-photon counting. A high repetition rate of 2 kHz was achieved by use of a readout camera with built-in image processing capabilities. The effects of sweep jitter were removed by using a UV timing reference. The use of single-photon counting allows the camera to re
Background: Ghrelin, an endogenous ligand for the growth hormone secretagogue receptor (GHSR), has two major functions: the stimulation of the growth hormone production and the stimulation of food intake. Accumulating evidence also indicates a role of ghrelin in cancer development. Methods: We conducted a case-control study to examine the association of common genetic variants in the genes coding
The most commonly used technology currently used for autoradiography is storage phosphor screens, which has many benefits such as a large field of view but lacks particle-counting detection of the time and energy of each detected radionuclide decay. A number of alternative designs, using either solid state or scintillator detectors, have been developed to address these issues. The aim of this stud
Fermented milk is commonly eaten during breakfast or as a snack between meals either in one-portion cups or from a bowl with a spoon. Approximately 5-10% of the fermented milk remains in the packages upon pouring, which during the last years, has received attention in public media as newspapers and television. This is a problem, not only from an economical point of view, but also from an ecologica
In order to explore verbal-nonverbal integration, we investigated the influence of cognitive and linguistic ability on gaze behavior during spoken language conversation between children with mild-to-moderate hearing impairment (HI) and normal-hearing (NH) peers. Ten HI-NH and 10 NH-NH dyads performed a referential communication task requiring description of faces. During task performance, eye move
P>Background: Studies of the nasal lavage fluid proteome have previously identified proteins differently expressed in patients with symptomatic allergic rhinitis, e.g. S100A7, prolactin-inducible protein (PIP), wingless-type MMTV integration site family, member 2B (WNT2B), Charcot-Leyden crystal protein (CLC) and palate lung nasal epithelial clone (PLUNC). The aim of the present study was to inves
Current sampling of genomic sequence data from eukaryotes is relatively poor, biased, and inadequate to address important questions about their biology, evolution, and ecology; this Community Page describes a resource of 700 transcriptomes from marine microbial eukaryotes to help understand their role in the world's oceans.
I religionernas värld har man alltid varit medveten om vilken betydelse ljud och tystnad har för vårt välbefinnande. Ibland framhävs tystnaden; i andra fall kan det röra sig om det monotona ljude av exempelvis en upprepad bön. Sådana övningar blir föremål för en psykologisk kommentar.
I denna artikel tar jag upp ett berättargrepp, den narrativa syllepsen, som inte fått någon större uppmärksamhet i litteraturteorin hittills. Den narrativa syllepsen definierades först av den franske litteraturteoretikern Gérard Genette år 1972 som ett berättargrepp där olika temporaliteter smälter samman. Begreppet har dock inte använts i någon större utsträckning därefter, vilket jag anser vara In this article I discuss a narrative device, the narrative syllepsis, which has not received much attention in literary theory until now. The narrative syllepsis was first defined by French literary theorist Gérard Genette as a narrative device where different temporalities merge. The concept has however not been used att a larger scale after Genette, something I find surprising taking into consi
This article aims to explore critically the role of an action research team in the social construction of interorganizational collaboration aimed at transgressing organizational and professional boundaries. We argue that the new relationships, actor conceptions and in some cases forms of work organization arising from the change process have been socially constructed through the discursive interve
A search for events with large missing transverse momentum, jets, and at least two tau leptons has been performed using 2 fb(-1) of proton-proton collision data at root s = 7 TeV recorded with the ATLAS detector at the Large Hadron Collider. No excess above the Standard Model background expectation is observed and a 95% CL upper limit on the visible cross section for new phenomena is set, where th
Genomgång av illustrationer till Axel Wallengrens "fakiriska" verk och hur dessa förhåller sig dels till själva texterna och dels till dessas upphovsman.
Popular AbstractAvhandlingens titel Den goda viljans paradoxer skall förstås på följande sätt. I utredningar och propositioner hävdar utredare, skolpolitiker och administratörer att lärarna skall bemyndigas, det vill säga de skall tillskrivas ett mandat i skolan. Detta mandat skall ge lärarna ett visst självständigt beslutsfattande i en ny mötesform som kallas arbetsenheter. Denna mötesform stipulThe theory and practice of reform as reflected in teachers’ experience of meetings in schools. This empirical study has been carried out in a coeducational school for pupils up to the age of 16 ("grundskola") during the school years 1988-89 up to and including 1991/92. In this study 26 teachers and five school administrators - head teachers and deputy-head teachers - have been interviewed. Person
The molecular self-diffusion in concentrated aqueous mixtures based on an oppositely charged po ymer-surfactant pair has been investigated by NMR pulsed field gradient techniques. The investigated structures were an ordered cubic Pm3n phase (ca. 50 wt % water) and a disordered micellar phase, both containing cetyltrimethylammonium (CTA(+)) micelles with mixed acetate (Ac-) and polyacrylate (PA(-))
Investigation of travel-domain dialogues reveals travel-agent (apSystem) utterances with intonational contours characterized by late-timed focal accents on given information. These accents occur on content words in utterance-initial position. The accentuation can be assumed to be related to the interactive nature of the dialogue in which the travel agent links back to a domain-related concept intr
Using DTT and iodoacetamide as a novel irreversible method to inhibit endogenous violaxanthin de-epoxidase, we found that violaxanthin could be converted into zeaxanthin from both sides of the thylakoid membrane provided that purified violaxanthin de-epoxidase was added. The maximum conversion was the same from both sides of the membrane. Temperature was found to have a strong influence both on th
The breakdown of traditional marine tenure systems and overexploitation of marine organisms as a result of rapid modernization, urbanization and population growth in the case of Tonga is outlined. The customary marine tenure system is described and the threats against the coral reefs are discussed. It is shown how accumulative strategies correlate with the move toward overexploitation. It is argue
Aims: To explore the prevalence of overweight in men and women in a Swedish rural community and to examine its associations with all-cause mortality. Methods: A community-based cohort study. A total of 1,109 men and women aged ≥40 years participated in a survey of cardiovascular disease (CVD) risk factors in the city of Skara in Skaraborg, Sweden, in 1993—94. Overweight was defined as a BMI≥25.0 k
