Multi-step synthetic pathways to low-ion exchange capacity (IEC) polysulfone (PSU) with sulfonic acid functionalized aliphatic dendrons and sulfonated comb-type PSU structures are developed and investigated in a comparative study as non-fluorinated proton exchange membrane (PEM) candidates. In each case the side chains are synthesized and introduced in their sulfonated form onto an azide-functiona
Sustainability degree programs in higher education have proliferated with the emergence of sustainability as a recognized academic field. This study evaluated the curricula of English-language programs granting degrees in sustainability by analyzing 27 bachelor's and 27 master's sustainability programs based on their (1) curricular structure, in terms of the proportion of core versus elective cour
Nanowire heterostructures are of special interest for band structure engineering due to an expanded range of defect-free material combinations. However, the higher degree of freedom in nanowire heterostructure growth comes at the expense of challenges related to nanowire-seed particle interactions, such as undesired composition, grading and kink formation. To better understand the mechanisms of ki
Prediction of recurrence in patients with unprovoked venous thromboembolism (VTE) remains a challenge. Studies of atherosclerosis suggest a protective role of transforming growth factor (TGF)-β. However, the role of TGF-β has not been studied in VTE. The aim of this study was to investigate TGF-β as a predictive marker of recurrent VTE in patients with a first episode of unprovoked VTE. Patients i
Measuring lifetime of photogenerated charges in semiconductor nanowires (NW) is important for understanding light-induced processes in these materials and is relevant for their photovoltaic and photodetector applications. In this paper, we investigate the dynamics of photogenerated charge carriers in a series of as-grown InP NW with different levels of sulfur (S) doping. We observe that photolumin
Agricultural intensification has been vital for meeting global food demand but has caused environmental degradation. This has disrupted the ability of soil to provide vital ecosystem services. Organic farming is often thought to conserve and utilise soil ecosystem services, and thus be a more sustainable method of food production than conventional farming. However, evidence for this is equivocal,
One decade ago Bonini et al. [Langmuir 2006, 22, 1478-1484] reported the occurrence of aggregates of beta-cyclodextrin in aqueous Solutions with sizes in the range from 90 nm to a few micrometers. The experimental technique used was cryo-TEM. This work followed a number of previous studies involving other physical parameters, such as viscosities and activity coefficients, the results of which were
Online evaluations are one of the most important innovations in tourism in recent years, often combining a review/rating (business-specific evaluation) and a ranking (inter-business comparison). As online reputation determines economic success, tourism managers may be tempted to manipulate online content. This paper presents the results from a qualitative study involving 20 hotel managers in south
Background: Lymphoid neoplasms are a heterogeneous group of cancers that originate in the lymphatic cells of the immune system. Several risk factors have been identified or suggested, but they all account for only a small proportion of the lymphoid neoplasm incidence. It has been hypothesised that regular exercise may modulate the immune system and thereby reduce the risk of developing the disease
Accuracy of absorbed dose calculations in personalized internal radionuclide therapy is directly related to the accuracy of the activity (or activity concentration) estimates obtained at each of the imaging time points. MIRD Pamphlet No. 23 presented a general overview of methods that are required for quantitative SPECT imaging. The present document is next in a series of isotope-specific guidelin
This study aims to evaluate if children's affective experience of every-day travel varies depending on travel mode and destination of travel. More specifically, what are children's reported valence (unpleasantness-pleasantness) and activation (deactivation-activation) while travelling to different destinations and does this experience have spill-over effects on how they perceive activities at the
The dual-phase alloy Zr2.5Nb alloy is an important nuclear material, because of its use in current and possible use in future nuclear reactors. It is, however, well-known that Zr2.5Nb weldments can fail through a time-dependent mechanism called delayed hydride cracking which is typically driven by the presence of tensile residual stresses. With a view to understanding the development of residual s
Due to the recent European legislations posing a ban of animal tests for safety assessment within the cosmetic industry, development of in vitro alternatives for assessment of skin sensitization is highly prioritized. To date, proposed in vitro assays are mainly based on single biomarkers, which so far have not been able to classify and stratify chemicals into subgroups, related to risk or potency
The aim of this article is to describe and investigate how the Swedish escalation in consumption and restructuring of retail spaces are dealt with in Swedish spatial planning. The first part contains a history and overview of the Swedish retail evolution. The major changes are presented, followed by a short discussion of some main actors in this evolution. In the second part we focus on policies a
Taking advantage of the unconventional reactivity of twisted mono- and bis-amides of Tröger's base (TB), rac-6 and rac-7, respectively, the first synthesis of a 6-endo-monosubstituted TB analogue, rac-9, and the first rational synthesis of a 6,12-endo,endo-disubstituted TB analogue, rac-11, have been achieved. The bis-TB crown ether, meso-13, was prepared starting from rac-7. Meso-13 constitutes a
Background: There is a paucity of instruments designed to evaluate the multiple dimensions of the workplace as an educational environment for undergraduate medical students. Aim: The aim was to develop and psychometrically evaluate an instrument to measure how undergraduate medical students perceive the clinical workplace environment, based on workplace learning theories and empirical findings. Me
Objective: To review research articles in psychiatry and psychology involving Latin American populations and/or produced by Latin American scholars to investigate the differential diagnosis between spiritual/anomalous experiences and mental disorders in order to contribute to the validity of the International Classification of Diseases towards its 11(th) edition in this area. Method: We searched e
Hyperglycaemia and glucose degradation products (GDPs) are closely associated with oxidative stress and inflammation in diabetic patients, a condition that leads to endothelial dysfunction and cardiovascular problems. We evaluated the effect of citrate and gluconate on glucose- and GDP-induced endothelial inflammation by measuring changes in viability, inflammation and function in primary human um
The strength of forward-backward (FB) multiplicity correlations is measured by the ALICE detector in proton-proton (pp) collisions at = 0.9, 2.76 and 7 TeV. The measurement is performed in the central pseudorapidity region (|eta| < 0.8) for the transverse momentum p (T) > 0.3 GeV/c. Two separate pseudorapidity windows of width (delta eta) ranging from 0.2 to 0.8 are chosen symmetrically around eta
