The COVID-19 pandemic had imposed a city-level quarantine, local lockdown, and border closures for patient-level isolation to control virus spread. There is a lack of studies on the health-related quality of life (HRQoL) in the elderly in countries like India during COVID-19. After obtaining written informed consent from the elderly patients, data was recorded in the case record form-cum-questionnaire. The quality of life was assessed with the help of Centers for disease control and prevention (CDC) HRQoL-14 measur [...]

We describe here the coherent formulation of electromagnetism in the non-relativistic quantum-mechanical many-body theory of interacting charged particles. We use the mathematical frame of the field theory and its quantization in the spirit of the quantum electrodynamics (QED). This is necessary because a manifold of misinterpretations emerged especially regarding the magnetic field and gauge invariance. The situation was determined by the historical development of quantum mechanics, starting from the Schrödinger e [...]

A filtered Poisson process is proposed as a model for river flows. With the help of real-life data, the model parameters are estimated. Mathematical formulae are derived in order to estimate the various return periods of the river. An application to two rivers shows that the point estimates are very close to the corresponding values computed by hydrologists, based on historical data. Moreover, by modifying the values of the parameters in the model, we can see the potential effects of climate change on the return pe [...]

Ozone was reacted with the aromatic membrane polyetheretherketone (PEEK) to form oxidized functional groups on the surface to enhance the attraction and transport of protons in fuel cells. Ozonation of unsaturated C-C sp2 bonds in PEEK formed a primary ozonide which dissociated to primarily produce O=C-O/O=C-OH moieties, and the root mean squared roughness factor (Rq) decreased from 7.4 nm, for the untreated sample, down to 3.1 nm. The oxidation of the surface and decrease in surface roughness made the surface incr [...]

The multi-dimensional measurement of complex biological systems and sub-systems is made possible by high-dimensional omics technologies. This frontier of research is promising for elucidating disease processes, physiological parameters, and therapeutic action mechanisms. Omics have potential merit for the integrative medicine field that is relatively early in terms of mechanistic research towards understanding the underlining therapeutic processes of mind-body interventions that show to affect multiple systems simu [...]

Ultraviolet (UV) and X-ray radiation are the primary causes of ionization that produce electron density in sufficient quantities to promote the propagation of satellite radio signals in the ionosphere. The electron densities suffer from spatio-temporal variations, and this poses different degrees of threats to satellite radio signals propagating through the ionosphere. We aimed to characterize the maximum electron density of the F2 layer (NmF2) in the middle-latitude ionosphere over Grahamstown, South Africa (Geogr [...]

Due to recent global warming and climate change events, about 127 countries have declared themselves carbon neutral since the Paris Agreement was signed. Furthermore, agriculture is directly or indirectly affected by climate change. In particular, the importance of carbon neutrality is very high due to the high carbon absorption potential of forestry biomass. In the global beverage market, green tea is the second most consumed beverage after water, and the potential of tea tree biomass to absorb carbon during culti [...]

Fabrication, arrangement, and controllable composition of ordered organometallic films are critical for designing a highly active catalyst and investigating the catalytic mechanism. In this paper, an organometallic terpyridine Pd(II)/Ni(II) monolayer linked on the silicon substrate surface (denoted as Si-Tpy-Pd1/Ni1) was prepared and characterized using water contact angle, ultraviolet spectra, X-ray diffraction, scanning electron microscopy, and X-ray photoelectron microscopy. Si-Tpy-Pd1/Ni1 exhibited high catalyt [...]

The COVID-19 pandemic has negatively impacted anti-violence centers for women. This study aims to investigate how the COVID-19 pandemic restrictions affect: the assistance and protection functions of the anti-violence centers; the needs of women victims of violence; and the well-being of the professionals working with these women. Twenty-four Italian anti-violence centers were involved, and 29 women working there were interviewed. From the qualitative analysis of the texts, three main themes were identified regardi [...]

The implementation of community-level de-centralised anaerobic digestion (AD) systems offers a sustainable solution for organic waste management and energy provision, but there is currently a need for low-cost methods of system control and management at this scale. The problem becomes accentuated with increasing deployment, as greater complexities are created by the need to both monitor and control a wider network of smaller, community-scale plants. This paper describes research to design, deploy and test such a sy [...]
