Obtaining of WC–Co- and WC–TiC–Co-Based Ultradispersive Alloys Modified with B4C–TiB2 QuasieuteticAbstract
Tungsten carbide WC-based materials characterized by high hardness and wear resistance have long been widely used in manufacturing cutting and mining tools. They are alloyed or modified with different ceramic phases to improve operational characteristics further. There are obtained the hard tungsten carbide–cobalt WC–Co and tungsten carbide–titanium carbide–cobalt WC–TiC–Co metal-ceramic alloys ultradispersed powders modified with quasieutectic ceramic alloy B4C–30wt.%TiB2 [...] 1595 11811 |
Analysis of Correlations for the Prediction of the Entrainment Fraction of Droplets in Gas-liquid Annular Flowsby
Mariana P. Koss
and
Luiz E. M. Lima
Abstract
In gas-liquid flows, droplets that detach from the liquid film lining the internal walls of a pipe and merge with the gas flowing through the pipe follow an annular flow pattern. This work analyzes correlations for estimating the entrainment fraction of such droplets contained in the literature by comparing their predictions with experimental data also from the literature. The results of this comparative study demonstrate that the analyzed correlations do not accurately reproduce experimental conditions. This is du [...] 1927 11800 |

Abstract
We explored the feasibility of a virtual-reality delivered mindfulness training intervention on burnout symptoms among corporate employees and clinicians in the Intensive Care Unit and Palliative Care Unit (PCU). To develop the VR mindfulness intervention we leveraged the Capability, Opportunity, Motivation, Behavior model (COM-B) as a guide for the design and implementation of the VR mindfulness training intervention. Using a pre-posttest within subjects design we assessed burnout syndrome, job stress and work-rel [...] 985 11794 |
Problems Associated with the Measurement of Neuropsychiatric Symptoms of DementiaAbstract
Neuropsychiatric symptoms (NPS) affect nearly all persons living with dementia (PLWD) at some point during the course of the disease. Given the absence of a cure or effective pharmacotherapy for dementia, it is particularly important to prevent, measure, track, and manage NPS in dementia care. Unfortunately, these efforts are hindered by inconsistent operational definitions and measurement tools for numerous neuropsychiatric symptoms. This review examines agitation, aggression, restlessness, and rejection of care a [...] 1877 11791 |
Neurochemical System Involved in Anorexia NervosaAbstract
Anorexia nervosa is a psychiatric disorder, the etiopathogenesis of which is still not fully understood. Currently, the most accredited model is a multifactorial model, which involves interaction between predisposing factors of biological nature, partly genetically determined, and psychological/personological and environmental socio-cultural factors. The last 20 years have led to the advancement in our knowledge on the mechanisms of energy homeostasis maintenance. There has been a veritable explosion of studies aim [...] 1359 11791 |
Sleep and Help Seeking Behaviours in Australia: A Narrative ReviewAbstract
Inadequate sleep is a largely under recognised problem in Australia despite researchers consistently highlighting it as a key component of health and wellbeing. Over a third of Australian adults now experience some form of inadequate sleep, which is consistently linked to a range of accompanying physical and mental health concerns. In addition to the health burden on the individual, the associated financial burden incurred by the community is extremely high with inadequate sleep costing over 66.3 billion annually i [...] 1412 11772 |
Recent Progress in the Development of Molecular Electrocatalysts for Formate Oxidationby

Sriram Katipamula
Abstract
Fuel cells based on renewable synthetic fuels are promising alternatives to fossil fuel combustion for efficient electricity production. Much focus has been placed on hydrogen as a chemical fuel, but being a flammable gas, there are challenges with its safe handling. Formic acid is an attractive liquid fuel for use in direct formic acid or formate fuel cells, and it can in principle be produced from the thermal or electrochemical reduction of carbon dioxide. Over the past ten years, advances have been made in the d [...] 1597 11765 |
Effects of Quantum Confinement of Hydrogen in Nanocavities – Experimental INS Results and New InsightsAbstract
Current developments of non-relativistic quantum mechanics appear to predict, and reveal, counter-intuitive dynamical effects of hydrogen in nanostructured materials that are of considerable importance for basic research as well as for technological applications. In this review, the experimental focus is on H2O and H molecules in carbon nanotubes and other nanocavities that have been experimentally investigated using the well-established technique of incoherent inelastic neutron scattering (INS). For instance, the [...] 2091 11764 |
Analysis of Surface Water Areal changes using Remote Sensing Databy

Mehdi Khaki
Abstract
Inland water bodies are crucial for supporting human life in various parts of the world. Therefore, it is essential to accurately monitor its spatiotemporal variations for better water management. The main objective of this study is to investigate the application of remote sensing data for quantifying the surface area changes and the impact of climatological variabilities over Lakes Mead and Chapala. Historical time series of monthly surface area dynamics were developed using Landsat 1-8 scenes and the climate vari [...] 1615 11763 |
