In this study, we used an image neural network model to assess the relationship between economic growth, pollution (PM2.5, PM10, and CO2), and deaths from COVID-19 in the Hubei area (China). Data analysis, neural network analysis, and deep learning experiments were carried out to assess the relationship among COVID-19 deaths, air pollution, and economic growth in China (Hubei province, the epicenter of the COVID-19 pandemic). We collected daily data at a city level from January 20 to July 31, 2020. We used main cit [...]

Charge transfer and mobility are essential for electrochemical processes in batteries, which need to be understood in detail for optimization, especially in the case of all-solid-state batteries. Wide line NMR is well-known in solid-state NMR and allows the quantification of ion mobility in ordered crystalline and amorphous structures. Temperature-dependent 23Na-NMR is sensitive to ion mobility via longitudinal relaxation, but also via line analysis and transverse relaxation. As 23Na is a spin 3/2 nucleus, 23Na-NMR [...]

Due to the massive increase in polymer manufacture, there has been a remarkable increase in plastic waste. With fewer landfills being used to dump plastic waste each year, it is becoming increasingly important to use effective recycling methods for plastic waste decomposition. In the present work, waste polystyrene was degraded in the presence of natural clay (K0.02, Ca0.15 [Mg0.25, Al0.69, Fe0.06], [Si2.0, Al0.6] O6.8 (O10) nH2O). The waste polymer was pyrolyzed at different heating rates i.e., 5, 10, 15 and 20&#x [...]

The TiO2/MCM-41 nanomaterials were synthesized by impregnation with an excess solvent with different percentages of titanium dioxide. They were used for catalytic degradation of Benzene Toluene Ethylbenzene and Xylenes (BTEX) in the presence of hydrogen peroxide in aqueous media. The obtained materials were characterized by X-ray Diffraction, nitrogen adsorption-desorption using the BET method and Fourier Transform Infrared Spectroscopy. The nanostructured phase of the hexagonal ordered materials was obtained even [...]

Adverse and traumatic childhood experiences can have profound negative health and mental health consequences across the lifespan. Prevention and early intervention strategies to mitigate such impacts and foster resilience are essential, yet extant approaches often do not consider the systemic nature of trauma exposure, particularly among communities most impacted by the COVID-19 pandemic and historic disinvestment. Addressing the impacts of trauma early in life is critical in order to mitigate their long-term effec [...]

The novel coronavirus COVID-19 is a viral pathogen that first emerged in Wuhan, China in 2002 and has spread to 202 countries (as of March 28, 2020) [1]. Despite the fact that the 2005 SARS-CoV pandemic infected over 8,500 people, and caused over 800 deaths with billions of dollars in economic loss worldwide, as of 2015 there were still no clinically approved antiviral drugs, vaccines or monoclonal antibody therapies to treat SARS-CoV infections [2]. Antiviral medications that have been used to treat or control oth [...]

Due to the increasing need to further develop the world gas and oil industry and the increased public attention to clean energy sources, studying and preventing Hydrogen Induced Cracking is one of the main safety concerns in nuclear power plants, oil pipelines and platforms. In this article, the growth and incubation times for internal Hydrogen Induced Cracks (HIC) are examined. Specifically, these times are modeled in two separate phases - the first phase (I) is a long time approximation, when the crack growth is [...]

Loneliness, social isolation, aloneness, and solitude may be used interchangeably by some who may miss the difference between them. Loneliness is the experience of being alone, or perceiving that one is alone and unimportant to others. Solitude is being geographically isolated out of one’s choice. Loneliness is not a feeling, but a multidimensional construct which is expressed cognitively, behaviorally and affectively. solitude is also reviewed and a clear distinction between loneliness and solitude is established.

In the U.S., older adults aged 65 or above comprise nearly one quarter of the solid organ transplant (SOT) waitlists, and the number of transplants performed in this age group continues to increase. There are no specific guidelines for the assessment and follow up of the older SOT candidate or recipient. Older adults are at increased risk of infectious complications after SOT. Despite these complications and even with the use of suboptimal donors, overall outcomes are favorable. We provide an overview to specific c [...]

In the recent past, laser therapy has made immense progress as it is known to change microcirculation, modulate vegetative parameters, and stimulate mitochondrial activity in the human body. This editorial briefly describes a new laser watch prototype (generation 2021), which can be used to perform continuous and simultaneous blood irradiation at the radial and/or ulnar artery of the wrist with different wavelengths of laser light. In a preliminary measurement, the increase in regional oxygen saturation at the croo [...]
