The origin of fine structure in the core-level photoemission spectra of the C2H4, C2D4, C2H3 and C2D3 molecules chemisorbed on Rh(111) is probed in a careful high-resolution study showing that this structure arises from internal molecular vibrations rather than from other chemically-shifted carbon atoms. It is shown by comparison of the adsorbate and gas-phase spectra that the underlying features

The aim is to explore experiences and considerations of social workers regarding irregular migrants, understood as being prone to be “collateral damage.” It is revealed that some social workers approve assistance exceeding that which can find support in the national legislation. They are hereby addressing the normative conditions for recognition and installing new frames for apprehending irregular

While the terms soft power, public diplomacy (PD) and nation brands have cemented their place in academic discourse during the early 21st century, the evaluation of these activities has not been given anywhere near the same level of attention. When describing how campaigns are evaluated, scholars tend to make assumptions based on the goals or outputs of an initiative rather than on the basis of re

OBJECTIVES: Deficits in cognitive function remain prevalent in HIV-infected individuals. The aim of this European multicentre study was to assess factors associated with cognitive function in antiretroviral therapy (ART)-naïve HIV-infected subjects at the time of enrolment in the NEAT 001/Agence Nationale de Recherche sur le SIDA (ANRS) 143 study.METHODS: Prior to starting ART, seven cognitive tes

Synovial fluids from 6 of 12 patients with rheumatoid arthritis (RA) and from 3 of 11 patients with reactive arthritis contained measurable levels of tumor necrosis factor α (TNFα). Seven of 12 sera from RA patients contained TNFα, while only 1 of those from reactive arthritis patients was positive. Gamma-interferon was detected in the synovial fluids and sera of only the RA patients. Tumor necros

Organic farming not only increases plant diversity, but also simultaneously promotes biological weed control through provisioning of ample resources to seed predators. Harpalus affinis (Schrank, 1781) was collected from organically or conventionally managed winter-wheat fields with high or low surrounding shares of organic fields, aiming to test the impact of agricultural management on its activit

Expanded CAG repeats lead to debilitating neurodegenerative disorders characterized by aggregation of proteins with expanded polyglutamine (polyQ) tracts. The mechanism of aggregation involves primary and secondary nucleation steps. We show how a noncanonical member of the DNAJ-chaperone family, DNAJB6, inhibits the conversion of soluble polyQ peptides into amyloid fibrils, in particular by suppre

Two different cDNAs, homologous to genes for rotenone-insensitive NADH dehydrogenases of bacteria and yeast, were isolated from potato. The encoded proteins, called NDA and NDB, have calculated molecular masses of 55 and 65kDa, respectively. The N-terminal parts show similarity to mitochondrial targeting peptides and the polypeptides are in vitro imported into potato mitochondria. Import processin

Copper (Cu) is considered to be an indispensable microelement for plants. Excessive Cu, however, is toxic and disturbs severalprocesses in the plant. The present study addressed the effects of ionic Cu (2.0 mMand 8.0mM) on mitosis, the microtubule cytoskeleton,and DNA in root tip cells of Allium cepa var. agrogarum L. to better understand Cu toxicity on plant root systems. The results indicated th

In the present work, effects of loading scheme and strain reversal on structure and hardness evolution have been studied by using high pressure torsion (HPT) and twist extrusion (TE) techniques. High purity aluminium (99.99%) was processed at room temperature up to a maximum total equivalent strain of εmax ≈ 8 by TE, and HPT in monotonic and reversal deformation modes with strain increment Δεmax =

Background and purpose: Impulse control disorders (ICDs) in Parkinson's disease (PD) are associated primarily with dopamine agonist (DA) use. Comparative surveys of clinical occurrence of impulse control behaviours on longer acting/transdermal DA therapy across age ranges are lacking. The aim of this study was to assess the occurrence of ICDs in PD patients across several European centres treated

Detailed time- and space-resolved SAXS experiments show the variation with hydration of liquid crystalline structures in ethanol-cast 5-80 μm thick films of polyion-surfactant ion "complex salts" (CS). The CS were dodecyl- (C12) or hexadecyl- (C16) trimethylammonium surfactants with polyacrylate (DP 25 or 6000) counter-polyions. The experiments were carried out on vertical films in humid air above

Cycle-resolved end-gas temperatures were measured using dual-broadband rotational CARS in a single-cylinder spark-ignition engine. Simultaneous cylinder pressure measurements were used as an indicator for knock and as input data to numerical calculations. The chemical processes in the end-gas have been analysed with a detailed kinetic mechanism for mixtures of iso-octane and n-heptane at different

Introduction: Hypertension is among the most common non-communicable diseases, being the major cause of premature deaths worldwide. The co-existence of hypertension and diabetes mellitus increases the risk of cardiovascular events and death. Objective: To determine the prevalence of hypertension and associated factors among individuals with type II diabetes mellitus in the Kilimanjaro region, nort

Progressive habitat fragmentation threatens plant species with narrow habitat requirements. While local environmental conditions define population growth rates and recruitment success at the patch level, dispersal is critical for population viability at the landscape scale. Identifying the dynamics of plant meta-populations is often confounded by the uncertainty about soil-stored population compar

The COVID-19 pandemic amplified demands on parents regarding balancing childcare and working from home. How parents distribute responsibilities differs culturally, and governments undertook varied strategies to address COVID-19. Research indicates that the pandemic resulted in increased burden for mothers, but also that it created a novel situation in which parenting and working styles could be re
