Facilitated CO stripping: Partial metallization of TiO2 nanoparticles (NPs) by electroreduction in the molten, eutectic mixture of CaCl2 and NaCl at 600 °C produces nano- and submicro-sized Ti2O and CaδTiOx (perovskites, x/× δ 2) that can significantly promote the catalytic activity of Pt NPs towards the oxidation of CO and CH3OH in acidic solutions
The governance of agricultural resources, particularly seeds, has long been a site of contestation between corporate-aligned institutions promoting proprietary seed laws and smallholder farmers, civil society organisations, and food sovereignty advocates defending traditional seed systems and local control. In Ghana, the introduction and eventual passage of the Plant Variety Protection Act of 2020
The Siusi/Seis section has been measured for the δ13C signature across the Permian-Triassic Boundary (PTB) in high resolution on magnetostratigraphic samples from Scholger et al. (2000), enabling an exact correlation with magnetostratigraphic data. We show that the base of the short normal polarity magnetozone that has been reported from the evento-stratigraphic boundary correlates with a distinct
Phylogenies are central to many disciplines in biology. While disciplines such as systematics are focused on phylogenetic hypotheses themselves, other disciplines depend on robust and well-supported phylogenies in order to put biological data into evolutionary context through phylogenetic comparative studies. Examples of such fields are macroevolutionary research e.g. studying the evolution of a f
Conventional diagnostic methods often involve long incubation times due to limited fluid mixing in confined spaces, despite offering high sensitivity. Therefore, acoustic streaming was employed to enhance microscale advection, thereby improving biomolecular interactions and reducing assay duration. The micromixing capability was demonstrated by dispersing methylene blue (MB) in deionized water and
Registered nurses with a doctoral degree are important for the quality of care, nursing education, and nursing research. Still, postgraduate career paths are criticized for being too vague. To enable career path development, mapping of the current situation appears fundamental. The objective was therefore to chart the current professional positions and work conditions and to explore the future car
There has been a substantial rise in coronavirus disease 2019 (COVID-19) cases after adjusting the dynamic zero-COVID policy in China. We conducted a survey to investigate the self-perceived symptom profile and its association with vaccination status during this outbreak. There were 552 individuals in this survey. The infected individuals displayed various symptoms associated with different factor
Background: Growing evidences have advocated the potential benefits of traditional Chinese exercise (TCE) on symptomatic improvement of knee osteoarthritis (KOA). However, most of them have been derived from cross-sectional studies or case reports; the effectiveness of TCE therapies has not been fully assessed with a randomized control trial (RCT). In order to evaluate the combined clinical effect
Sveriges skogar påverkas av de hastiga globala klimatförändringarna. Inverkan av klimatförändringana syns redan med både ökad frekvens och kraftigare extremväder som stormar, värmeböljor, torka och skyfall. Ett tydligt exempel är den extrema torka som drabbade hela landet år 2018. Till följd av torkan har det bland annat skett en explosionsartad ökning av antalet granbarkborrar som angriper och döA changing climate is expected to lead to more extreme weather events, such as an increased frequency of droughts and forest fires. Changing forest conditions can offer benefits to species such as insects, including bark borers that thrive in warm conditions. Warmer temperatures also favor the acceleration of ozone (O3) production, which can cause stress on vegetation. Vegetation stress can have n
The discipline of epidemiology, which holds major influence on public health policy as well as on clinical medical practice, has in recent decades to a large extent been concerned with the identification of factors and markers of risk for disease. Much health information and intervention is thus informed by a wealth of studies on a variety of risk factors, of which the individual is encouraged to
We describe quantum-size and binding-site effects on the chemical and local field enhancement mechanisms of surface-enhanced resonance Raman scattering (SERRS), in which the pyridine molecule is adsorbed on one of the vertices of the Ag-20 tetrahedron. We first investigated the influence of the binding site on normal Raman scattering (NRS) and excited state properties of optical absorption spectro
This paper presents the development of an experimentally validated model that mechanistically comprehends the complex interaction between the gas-phase fluid dynamics, the mass transport of individual species, and the heterogeneous gas-surface reaction mechanism in a continuous cross-flow atomic layer deposition (ALD) reactor. The developed ALD gas-surface reaction mechanism, purely based on conse
The aim of this thesis was to explore and gain deeper insight into and understanding of mobility in public environments for people with acquired cognitive functional limitations (target group of this thesis) and of reasons why some of them do not use public transport. Using an explorative approach, the target group’s mobility was firstly discussed by experts in focus group interviews. Secondly the
We present a re-analysis of the Geneva-Copenhagen survey, which benefits from the infrared flux method to improve the accuracy of the derived stellar effective temperatures and uses the latter to build a consistent and improved metallicity scale. Metallicities are calibrated on high-resolution spectroscopy and checked against four open clusters and a moving group, showing excellent consistency. Th
Film cooling effectiveness and its distribution characteristics on the gas turbine blade surface were investigated numerically. Seven rectangular ribs were located on the internal wall, and a film cooling hole had a compound inclined angle. The case with a compound angle of 45 degrees was designed to improve the lateral film cooling effectiveness on the downstream surface. The secondary flow jet f
Several studies of meteorites show that a large disruption of an asteroid occurred ca. 470 Ma in our solar system's asteroid belt. As a consequence, a large number of meteorite impacts occurred on Earth during the following few million years. The finding and characterization, for the first time, of planar deformation features in quartz grains from rocks collected at the Middle Ordovician Hummeln s
The production of events with multiple high transverse momentum particles including charged leptons and jets is measured, using 1.04 fb(-1) of proton-proton collision data recorded by the ATLAS detector during the first half of 2011 at root s = 7 TeV. No excess beyond Standard Model expectations is observed, and upper limits on the fiducial cross sections for non-Standard Model production of these
Chromosome banding analyses reveal secondary chromosome abnormalities in addition to the MYC translocations t(8;14)(q24;q32), t(8;22)(q24;q11), and t(2;8)(p11;q24) in 60%-80% of Burkitt lymphomas/leukemias (BL). The high incidence of such aberrations indicates that additional changes are important, perhaps necessary, for malignant transformation, i.e., the 8q24/MYC rearrangements may not be suffic
