Does using public transport affect tourist subject well-being and behaviour relevant to sustainability? Value-attitude-behaviour theory and artificial intelligence benefits

Increasing tourist use of public transport is a potentially significant means of reducing greenhouse gas emissions. There are limited theoretically informed studies that focus on domestic tourist use of public transport, particularly in an Asian cultural context (e.g. South Korea). To bridge the research gap, this study applies and tests an extended value-attitude-behaviour (EVAB) theory, includin

Structure and propagation of spherical turbulent iron-methane hybrid flame at elevated pressure

In this communication we demonstrate the role of turbulence intensity in the dual-front structure and self-similar propagation of spherical turbulent iron-methane hybrid flames. We first show that iron-methane hybrid mixture, whose iron concentration is below a critical threshold for the formation of a dust flame front in laminar or weak turbulent environment, can be burned strongly with both sepa

Resonant Inner-Shell Photofragmentation of Adamantane (C10H16)

Adamantane, the smallest diamondoid molecule with a symmetrical cage, contains two distinct carbon sites, CH and CH2. The ionization/excitation of the molecule leads to the cage opening and strong structural reorganization. While theoretical predictions suggest that the carbon site CH primarily causes the cage opening, the role of the other CH2 site remains unclear. In this study, we used advanced

INFERNO : Galactic winds in dwarf galaxies with star-by-star simulations including runaway stars

The formation and evolution of galaxies have proved sensitive to the inclusion of stellar feedback, which is therefore crucial to any successful galaxy model. We present INFERNO, a new model for hydrodynamic simulations of galaxies, which incorporates resolved stellar objects with star-by-star calculations of when and where the injection of enriched material, momentum, and energy takes place. INFE

Moving past neonicotinoids and honeybees : A systematic review of existing research on other insecticides and bees

Synthetic pesticides (e.g. herbicides, fungicides and insecticides) are used widely in agriculture to protect crops from pests, weeds and disease. However, their use also comes with a range of environmental concerns. One key concern is the effect of insecticides on non-target organisms such as bees, who provide pollination services for crops and wild plants. This systematic literature review quant

Interplay between human STING genotype and bacterial NADase activity regulates inter-individual disease variability

Variability in disease severity caused by a microbial pathogen is impacted by each infection representing a unique combination of host and pathogen genomes. Here, we show that the outcome of invasive Streptococcus pyogenes infection is regulated by an interplay between human STING genotype and bacterial NADase activity. S. pyogenes-derived c-di-AMP diffuses via streptolysin O pores into macrophage

Development of a Survey Instrument to Explore Telehealth Adoption in the Healthcare Domain

The purpose of this paper is to present a validated and reliable survey instrument to explore the determinants of telehealth adoption by healthcare professionals in developing countries. The survey instrument has been procreated for measuring the determinants of telehealth adoption in the Indian healthcare domain. A research design was conceived whereby three stages of methodologies were applied t

Causes of nephrotic syndrome in Sweden: The relevance of clinical presentation and demographics

Background: Many pathological processes can disrupt the integrity of the glomerular capillary wall and cause a massive leakage of protein, resulting in nephrotic syndrome (NS). Clinical parameters such as age, sex, renal function, presence of diabetes, and how NS is defined influence the spectrum of underlying diseases. In this study, we examine how these parameters interact.Methods: Age, sex, hem

Controlled fabrication of gelatin nanoparticles as drug carriers

In recent years, significant effort has been devoted to develop nanotechnology for drug delivery since it offers a suitable means of delivering small molecular weight drugs, as well as macromolecules such as proteins, peptides or genes by either localized or targeted delivery to the tissue of interest. Nanotechnology focuses on formulating therapeutic agents in biocompatible nanocomposites such as

A multiparametric approach to predict triple-negative breast cancer including parameters derived from ultrafast dynamic contrast-enhanced MRI

Objective: Triple-negative breast cancer (TNBC) is a highly proliferative breast cancer subtype. We aimed to identify TNBC among invasive cancers presenting as masses using maximum slope (MS) and time to enhancement (TTE) measured on ultrafast (UF) DCE-MRI, ADC measured on DWI, and rim enhancement on UF DCE-MRI and early-phase DCE-MRI. Methods: This retrospective single-center study, between Decem

Teaching the Subject of Nursing—Academic Teaching Based on Dossey's Holistic Nursing Theory

Introduction: Being a teacher of nursing education can be challenging. Nursing theories can guide clinical nurses in their work, but is it possible to apply a nursing theory in the context of academic teaching? Purpose: To investigate if it is possible to apply Dossey's holistic nursing theory into the context of teaching the subject of nursing. Conclusion: This article proposes that Dosseys holis

Grassroots austerity : municipal bankruptcy from below in Vallejo, California

Austerity appears to be a globally coordinated restructuring process, where international and national governments cooperate to stymie economic crisis and socialize the costs of systemic economic failure. However, austerity is also shaped from the bottomup. This paper examines the 2008 bankruptcy of Vallejo, California. This city of under 120 000 people became the first municipal bankruptcy in the

Invisible, Responsible Women in Sweden–Planning Pregnancies, Choosing Contraceptives

In this study I explore discourses of contraception and reproduction, which are drawn upon and reproduced in Swedish official online sources on contraceptive advice, through the theoretical frameworks of biomedicalization and reproductive justice. The analysis yielded three interwoven themes: 1) women in need of contraceptives have to balance discourses of exogenous hormones as both an “unnatural”

The Phylogenetic Placement of an Enigmatic Moth Egybolis Vaillantina Based on Museomics

Here, we present multi-locus sequencing results from the enigmatic Afrotropical monotypic genus Egybolis Boisduval (occurring in East- and South Africa—previously placed in the subfamily Catocalinae, Noctuidae). Model-based phylogenetic analysis places Egybolis within a strongly supported clade comprising four Old World Tropical genera Cocytia Boisduval, Avatha Walker, Anereuthina Hübner, and Serr

High-quality, thick III-nitride epitaxial drift layers with controlled doping are needed for next-generation highly efficient vertical power devices for a smart grid applications and electrification of mobility. Achieving desirable material properties, such as low background impurity concentrations and reduced dislocation densities in combination with high growth rates, necessary for practical app

Females with knee osteoarthritis use a detrimental knee loading strategy when squatting

Background: The purpose of this study was to identify sex differences in lower limb kinematics, kinetics, and muscle activation patterns between individuals with osteoarthritis and healthy controls during a two-legged squat. Method: Thirty OA (15 females) and 30 healthy (15 females) participants performed three 2-legged squats. Sagittal and frontal plane hip, knee, and ankle kinematics and kinetic

Using the auditory brainstem response elicited by within-channel gaps to measure temporal resolution

The Auditory Brainstem Response (ABR) can be used to measure the early temporal activity of the auditory system. A gapin- noise ABR has been developed to measure the electrophysiological response to auditory stimulation without attending to the task. In the present study, young adults passively listened to stimuli of various gap widths in separate sequences. In a single sequence, two identical 15

Effect of implementing magnetic resonance imaging for patient-specific OpenSim models on lower-body kinematics and knee ligament lengths

Background: OpenSim models are typically based on cadaver findings that are generalized to represent a wide range of populations, which curbs their validity. Patient-specific modelling through incorporating magnetic resonance imaging (MRI) improves the model's biofidelity with respect to joint alignment and articulations, muscle wrapping, and ligament insertions. The purpose of this study was to d

Relationship of Knee Forces to Subjective Function Pre- and Post-ACL Reconstruction

Purpose: Although basic objective measures (e.g., knee laxity, strength, and hop tests) have been related to subjective measures of function, associations between knee-specific objective and subjective measures have yet to be completed. The objective was to determine if knee joint contact and ligament forces differ between pre- and post-anterior cruciate ligament (ACL) reconstructed states and if

Knee joint kinematics and kinetics during the hop and cut after soft tissue artifact suppression : Time to reconsider ACL injury mechanisms?

The recent development of a soft tissue artifact (STA) suppression method allows us to re-evaluate the tibiofemoral kinematics currently linked to non-contact knee injuries. The purpose of this study was therefore to evaluate knee joint kinematics and kinetics in six degrees of freedom (DoF) during the loading phases of a jump lunge and side cut using this in silico method. Thirty-five healthy adu
