The results of a search for the direct pair production of top squarks, the supersymmetric partner of the top quark, in final states with one isolated electron or muon, several energetic jets, and missing transverse momentum are reported. The analysis also targets spin-0 mediator models, where the mediator decays into a pair of dark-matter particles and is produced in association with a pair of top
Objective: We endeavored to create a comprehensive course in global surgery involving multinational exchange. Design: The course involved 2 weeks of didactics, 2 weeks of clinical rotations in a low-resource setting and 1 week for a capstone project. We evaluated our success through knowledge tests, surveys of the students, and surveys of our Zimbabwean hosts. Setting: The didactic portions were h
The shear plate dowel joint (SPDJ) is a novel connection design for use in heavy timber structures. Load transfer between timber members is enabled using a single large diameter dowel and externally glued steel plates. The steel plates are glued to the timber using bond lines of low stiffness and high fracture energy to achieve a uniform shear stress distribution, thus maximizing the load carrying
Context. Detailed chemical abundances of Galactic stars are needed in order to improve our knowledge of the formation and evolution of our galaxy, the Milky Way. Aims. We took advantage of the GIANO archive spectra to select a sample of Galactic disc stars in order to derive their chemical inventory and to compare the abundances we derived from these infrared spectra to the chemical pattern derive
The MAX IV facility in Lund, Sweden consists of two storage rings for production of synchrotron radiation. The smaller 1.5 GeV ring is presently under construction, while the larger 3 GeV ring is being commissioned. Both rings will be operating with top-up injections from a full-energy injector. During injection, the electron beam is first delivered to the main injector from a thermionic pre-injec
To avoid the fierce competition for food, South African ball-rolling dung beetles carve a piece of dung off a dung-pile, shape it into a ball and roll it away along a straight line path. For this unidirectional exit from the busy dung pile, at night and day, the beetles use a wide repertoire of celestial compass cues. This robust and relatively easily measurable orientation behavior has made ball-
Wild birds, particularly duck species, are the main reservoir of influenza A virus (IAV) in nature. However, knowledge of IAV infection dynamics in the wild bird reservoir, and the development of immune responses, are essentially absent. Importantly, a detailed understanding of how subtype diversity is generated and maintained is lacking. To address this, 18,679 samples from 7728 Mallard ducks cap
Surface display in insect cells: Systems available for surface display that utilize bacterial phages are insufficient for displaying a number of eukaryotic proteins. By instead presenting proteins on the surface of eukaryotic cells or virus, some of these problems might be overcome. The baculovirus/insect cell system, which has a high expression rate and post-translational mashinery closely resemb
Previous research has shown a male bias in the media. This study tests this statement by examining how the pronouns She and He are used in a news media context. More specifically, the study tests whether He occurs more often and in more positive semantic contexts than She, as well as whether She is associated with more stereotypically and essential labels than He is. Latent semantic analysis (LSA)
Today, there is considerable interest in integrated forest biorefineries which, besides pulp, produce high-value-added products, such as, polymers and carbon fibres. Lignin is the major non-cellulosic constituent of wood. It is a complex, amorphous highly crosslinked polyphenolic. Lignosulphonate in spent liquor in sulphite mills has long been isolated using ultra filtration. Generally, precipitat
Object. Cerebral vasospasm following subarachnoid hemorrhage (SAH) leads to reduced cerebral blood flow (CBF) and to cerebral ischemia, in some cases even producing infarction and long-term disability. The goal of the present study was to investigate the hypothesis that inhibition of neurokinin-1 receptors (NK1Rs) by administration of L-822429 blunts the decrease in CBF as well as cerebrovascular
The orthogonality factor (OF) quantifies the loss of orthogonality between the signals transmitted simultaneously on a wideband code division multiple access (WCDMA) downlink due to multipath dispersion. It is one of the fundamental parameters that determines the signal-to-interference-plus-noise ratio at the output of the Rake receiver and, consequently, it has a significant impact on downlink sy
BACKGROUND: A synthetic oxytocin analogue, barusiban, was shown to potently inhibit oxytocin-induced activity of myometrium from term pregnant women. The responsiveness to vasopressin was not influenced by the compound. OBJECTIVE: To test the effect of barusiban and a reference compound, atosiban, on oxytocin-induced activity of myometrium from women at preterm pregnancy in comparison to myometriu
This study examines the motif of the Fallen World in Coleridge’s major poems The Ancient Mariner, Christabel and Kubla Khan . The use of Milton’s Paradise Lost as an intertextual foil throughout allows themes and metaphors inherent in the Fallen World motif to emerge in Coleridge’s poetry. A Fall presupposes a standard from which one has been separated downwards. Primarily, it is understood as man
A dosimetry system based on radioluminescence (RL) and optically stimulated luminescence (OSL) from carbon doped aluminium oxide (Al2O3:C) crystals was developed for in vivo absorbed dose measurements in mammography. A small cylindrical crystal of Al2O3:C (diameter 0.48 mm and length 2 mm) was coupled to the end of a 1 mm diameter optical fibre cable. Owing to their small size and characteristic s
Refillable polyester bottles, for example polyethylene terephthalate (PET) bottles, are known to interact with chemicals. Aroma compounds from a product can be absorbed by the bottle material, remain after washing and remigrate when the bottle is reused, resulting in off-flavour of the new product. A certified reference material has recently been approved with which the chemical and sensory inertn
Abstract in Undetermined BACKGROUND: The absence of all Kell blood group antigens (K0 phenotype) is very rare. K0 persons, however, can produce clinically significant anti-Ku (K5) after transfusion and/or pregnancy and require K0 blood for transfusion. Ten alleles giving rise to the K0 phenotype have been reported: different populations were studied although none from Scandinavia. STUDY DESIGN AND
Introduction: The proportion of elderly patients who are undernourished is high and undernutrition has serious health implications. No consensus exists regarding nutritional screening measurements suitable for elderly patients. There is a need to identify risk factors for undernutrition in elderly patients to enable prevention and treatment. Aim: To identify clinically identifiable risk factors fo
The cycloruthenation of 2-phenylimidazole (phim) by [Ru(6-C6H6)(-Cl)Cl]2 in acetonitrile in the presence of NaOH has been carried out. The unstable intermediate [Ru(phim)(MeCN)4]PF6 formed has been converted into the complexes [Ru(phim)(4,4′-Me2bpy)(MeCN)2]PF6 (2) and [Ru(phim)(LL)2]PF6 (3, LL=phen (a), bpy, 4,4′-Me2bpy), which were characterized by the mass-spectrometry, 1H-NMR spectroscopy, UV–v
