The hole transporting medium in solid-state dye-sensitized solar cells can be utilized to harvest sunlight. Herein we demonstrate that a triphenylamine-based dye, used as hole-transporting medium, contributes to the photocurrent in a squaraine-sensitized solid-state dye-sensitized solar cell. Steady-state photoluminescence measurements have been used to distinguish between electron transfer and en
Responding to today's often transboundary emergencies, frequently characterized by unclear root causes and indistinct responsibilities as well as multiple actors, will require that responding actors come together to meet societal needs and solve problems arising in relation to those needs. In collective problem solving, representing the problem is crucial, especially in emergency situations, where
In parallel with an unprecedented progress in vascular and stem cell biology during the past two decades, our understanding of vascular calcification has evolved from being perceived as a harmless, passive deposition of minerals to what we now consider a highly regulated, cell-mediated process that is strongly associated with chronic kidney disease (CKD) and confers increased risk for incident car
Worship space acoustics have been established as an important part of a nation’s cultural heritage and area of acoustic research, but more research is needed regarding the region of northern Europe. This paper describes the historical acoustics of an important abbey church in Sweden in the 1470s. A digital historical reconstruction is developed. Liturgical material specific to this location is rec
Background: The growth factor progranulin has been implicated in numerous biological processes such as wound healing, inflammation and progressive tumorigenesis. Both progranulin and its receptor sortilin are known to be highly expressed in subgroups of breast cancer and have been associated with various clinical properties including tamoxifen resistance. Recent data further suggest that progranul
The early stages of a galaxy's evolution leave an imprint on its metallicity distribution. We discuss the origins and evolution of radial metallicity gradients in discs of spiral galaxies using an analytical chemical evolution model. We explain how radial metallicity gradients in stellar populations are determined by three factors: the radial metallicity profile of the star-forming interstellar me
Visuals are ubiquitous in strategic communication involving social media and there are high expectations on what visual social media can accomplish with regards to creating engagement among people. The research aim in this paper is to examine how employees experience curating images in social media as part of an organization’s strategic communication. The reasoning is based on an empirical study o
We have found that the dissolution of cellulose in the binary mixed solvent tetrabutylammonium acetate/dimethyl sulfoxide follows a previously overlooked near-stoichiometric relationship such that one dissolved acetate ion is able to dissolve an amount of cellulose corresponding to about one glucose residue. The structure and dynamics of the resulting cellulose solutions were investigated using sm
Background: Functional electrical stimulation (FES) can be applied as an assistive and therapeutic aid in the rehabilitation of foot drop. Transcutaneous multi-pad electrodes can increase the selectivity of stimulation; however, shaping the stimulation electrode becomes increasingly complex with an increasing number of possible stimulation sites. We described and tested a novel decision support sy
The current study provides a social constructionist approach to crisis communication in the Chinese context. Crisis communication is viewed as a form of strategic communication, involving multiple stakeholders in situations that are dependent on context, space and time. This approach provides a much-needed path for investigating and understanding crisis communication practices in contemporary Chin
Purpose: The purpose of the study was to identify serum microRNAs providing a link between male subfertility and metabolic syndrome (MetS) and validate their diagnostic potential. Methods: Sera were analyzed for fertility and MetS-related parameters in subfertile men (n = 79) and controls (n = 38). Literature review identified miR-155-5p, miR-122-5p, miR-200a-3p, and miR-200c-3p which previously w
BACKGROUND:: Pneumococcal conjugate vaccine (PCV) was introduced in 2000. The first 7-valent vaccine was followed by a 13-valent vaccine (PCV13) with the same conjugate, and a 10-valent vaccine (PCV10), conjugated to protein D from H. influenzae. The vaccines offer some protection against pneumococcal acute otitis media (AOM), and, with PCV10, possibly also some protection against H. influenzae AO
The gut hormones ghrelin, glucagon-like peptide 1 (GLP-1), and glucose-dependent insulinotropic peptide (GIP) have been intensively studied for their role in metabolism. It is, however, not well known whether the hormones interplay and regulate the secretion of each other. In this study, we studied the effect of ghrelin on GLP-1, GIP, and insulin secretion during an oral glucose tolerance test (OG
Aims: People who have schizophrenia die earlier from somatic diseases than do people in the general population, but information about cardiovascular deaths in people who have schizophrenia is limited. We analysed mortality in all age groups of people with schizophrenia by specific cardiovascular diseases (CVDs), focusing on five CVD diagnoses: coronary heart disease, acute myocardial infarction, c
This report aims to introduce, test and discuss a new method of measuring episodic memory in participants with highly restricted verbal abilities. Although an elicited/deferred imitation paradigm has already proposed a successful method of measuring this capacity in infants as young as 6 months old [Bauer, Patricia J. 2006. “Constructing a Past in Infancy: A Neuro-Developmental Account.” Trends in
Background: The relationship between coffee consumption and mortality in diverse European populations with variable coffee preparation methods is unclear. Objective: To examine whether coffee consumption is associated with all-cause and cause-specific mortality. Design: Prospective cohort study. Setting: 10 European countries. Participants: 521 330 persons enrolled in EPIC (European Prospective In
