The regioselectivity in the Rh catalysed 1,4-hydrosilylation of isoprene was investigated. Variation of solvents and temperature did not significantly affect the isomer distribution between tail-product (I) and head-product (II). The choice of ligands had the greater influence, where Rh-I-based catalysts with the strong electron withdrawing ligand CO favoured production of isomer II, while Rh-I ca
Exterior letter pairs (e.g., d_k in dark) play a major role in single-word recognition, but other research (D. Briihl & A. W. Inhoff, 1995) indicates no such role in reading text. This issue was examined by visually degrading letter pairs in three positions in words (initial, exterior, and interior) in text. Each degradation slowed reading rate compared with an undegraded control. However, whe
The research applies media discourse analysis and late modernity theory to the social construction of the transnational Oresund Region between the South of Sweden and East of Denmark. Based on interviews with PR sources and journalists, analysis of newspaper texts and opinion polls, the study found that despite trans-national aims the region is mainly constructed through Swedish or Danish national
The coordination environment of uranyl in water has been studied using a combined quantum mechanical and molecular dynamics approach. Multiconfigurational wave function calculations have been performed to generate pair potentials between uranyl and water. The quantum chemically determined energies have been used to fit parameters in a polarizable force field with an added charge transfer term. Mol
Streams draining agricultural land are simultaneously exposed to multiple stressors including agricultural antibiotics and effluent from surface water run-off. The potential interactive effects of these contaminants on stream benthic communities are poorly understood. Using a streamside channel experiment with a full factorial, repeated-measures design, we assessed the individual and combined effe
HAMLET is a complex of human a-lactalbumin (ALA) and oleic acid and kills several Gram-positive bacteria by a mechanism that bears resemblance to apoptosis in eukaryotic cells. To identify HAMLET's bacterial targets, here we used Streptococcus pneumoniae as a model organism and employed a proteomic approach that identified several potential candidates. Two of these targets were the glycolytic enzy
To understand the biology and evolution of ruminants, the cattle genome was sequenced to about sevenfold coverage. The cattle genome contains a minimum of 22,000 genes, with a core set of 14,345 orthologs shared among seven mammalian species of which 1217 are absent or undetected in noneutherian (marsupial or monotreme) genomes. Cattle-specific evolutionary breakpoint regions in chromosomes have a
This article considers the ways in which geo-political and legal concerns materialised in debates over self-determination in the years following decolonisation, and how they impacted on its’ possibilities, objectives and conception. During this period, self-determination was not, as some scholars have argued, a declining norm, but one central to the competing visions of reinventing international l
Most pathogens can infect a number of different host species, but host species often differ considerably in susceptibility to a given pathogen. In the case of zoonotic pathogens, natural hosts typically present little or no disease symptoms, while humans and other “spill-over” hosts often present severe symptoms. Differences in susceptibility do not only occur between natural and non-natural hosts
A novel model-independent Lévy imaging method is employed for reconstruction of the elastic pp and pp¯ scattering amplitudes at low and high energies. The four-momentum transfer t-dependent elastic slope B(t), the nuclear phase φ(t) as well as the excitation function of the shadow profile P(b) have been extracted from data at ISR, Tevatron and the LHC energies. We found qualitative differences in
The insulin-releasing ability of some neutral and di-basic amino acids was studied in an in vitro system using micro-dissected pancreatic islets with a high proportion of insulin-producing β-cells. The neutral amino acids l-alanine and α-aminoisobutyric acid had no substantial effects on basal and glucose-stimulated insulin release. In contrast, 5–20 mm of the dibasic amino acid l-arginine gradual
A search for long-lived particles decaying into an oppositely charged lepton pair, μμ, ee, or eμ, is presented using 32.8fb−1 of pp collision data collected at s=13 TeV by the ATLAS detector at the LHC. Candidate leptons are required to form a vertex, within the inner tracking volume of ATLAS, displaced from the primary pp interaction region. No lepton pairs with an invariant mass greater than 12
Purpose: To investigate the change in proportion of high-volume cataract surgeons during the period 2007 to 2016 and determine the impact of operation volume per surgeon and clinical unit on the rate of capsule complications. Design: Retrospective, register-based study. Participants: Patients undergoing and surgeons performing cataract surgery at Swedish ophthalmologic departments 2007–2016. Metho
AIMS/HYPOTHESIS: Substantial deposition of the extracellular matrix component hyaluronan (HA) is characteristic of insulitis in overt type 1 diabetes. We investigated whether HA accumulation is detectable in islets early in disease pathogenesis and how this affects the development of insulitis and beta cell mass.METHODS: Pancreas tissue from 15 non-diabetic organ donors who were positive for islet
Electric vehicles have a potential to lower greenhouse gas emissions but still face challenges. This study asks what can be learned from the US automobile history. In 1900, there were three equal contenders in the US automotive industry: gasoline, electric and steam cars. Only a decade later, the gasoline car had achieved a crushing dominance. This dominance is often attributed to techno-economic
This article addresses the ways in which contemporary political processes, neoliberal market forces, and identity politics of the twenty-first century have affected the understanding of Swedish heritage. Examining the work being done at the Hallwyl Museum in Stockholm, Sweden and the American Swedish Institute in Minneapolis, Minnesota, we aim to illustrate how heritage is staged, performed, and e
