The objective of the paper is twofold: first, to review the classical diffusion models and show the approximations at the origin of the parabolic character of the classical equations; second, to demonstrate a connection between the quantum and classical models of diffusion. As diffusion is inherently related to the motion of constituents, the consistent models are framed within the dynamics of mixtures. The derivation of diffusion equations is then determined based on the related, pertinent approximations.

Electric vehicles are becoming popular among consumers while BS-VI norms have been introduced and mandated for conventional vehicles in India. In the present study, the environmental impacts from the use phase of electric two-wheeler (EV) and gasoline two-wheeler (GV) have been evaluated and compared using the life cycle assessment (LCA) perspective. The functional unit adopted was 1000 km driven by one vehicle under Indian road and traffic conditions. CML 2001 and ReCiPe 2016 methods were used for the assessment u [...]

Vanadium is an element that is widely distributed in Earth’s crust as well as in sea-water and ground-water reservoirs. Therefore, it exerts a great influence on the issues related to life and environment. Vanadium is utilized by several marine organisms. For example, there are vanadate-dependent haloperoxidases in algae and several bacteria, e.g., Azotobacter, use it for nitrogen fixation and bacterial reduction involves the conversion of vanadate to oxidovanadium (IV). The similarity between vanadate and phosphat [...]

Background: Human pancreatic islet transplantation is a minimally-invasive procedure that is gaining recognition for the treatment of type 1 diabetes (T1D). Selected patients with unstable T1D, hypoglycemia unawareness, history of severe hypoglycemia, and glycemic lability, not successfully stabilized with intensive insulin treatment, can be offered this alternative therapy that has been shown to provide long-term glycemic control with near-normalization of hemoglobin A1c in the absence of severe hypoglycemia. Toda [...]

Background: Death is a universal human experience. The experience of grief is unique for each person experiencing it. There is emerging research on modalities that provide support for bereaved individuals including bereavement massage. There is limited information in the literature about the specific role that massage can play in supporting bereaved individuals. The aim of this scoping review is to explore the literature that reports on the use and outcomes of bereavement massage so that massage therapists, consume [...]

Malnutrition and frailty are preventable and reversible. However, a significant proportion of aged care residents live with malnutrition and frailty which have associated complications such as increased falls, hospitalizations, infections, and decreased quality of life. Nutrition and dietary interventions can prevent these issues, however, there a few interventions conducted in this setting and no consensus on the most utilized interventions to improve health outcomes. In a crude literature search, we identified 65 [...]

Developing adsorbents with appreciable morphology will create new approaches for better phosphate adsorption performance. This study aims to investigate the design of an adsorbent by impregnating silver nanoparticles (AgNPs) onto calcium oxide-activated carbon (CaO-AC). The Ag/CaO-AC nanocomposite was used as an adsorbent to remove phosphate. Batch adsorption studies were performed to evaluate the effects of adsorbent dose, initial phosphate concentration, contact time, and pH on removing phosphate from an aqueous [...]

Multi-rotor and fixed-wing drones are extensively used to collect the data needed for producing large-scale topographic maps and plans. Several types of drone products are available, and the most important one for surveyors is an orthophoto. Flight planning, the quality of the control data, the assessment of drone products, and the image processing software need to be considered when using thes e drones. In this study, we explained these concepts and discussed their theoretical and practical importance in providing [...]

This narrative review of the literature on noninvasive brain stimulation techniques observes four neurostimulation domains: light therapy, photobiomodulation, a group of techniques within transcranial electric current and magnetic field stimulations, low-frequency sound stimulations, including vibroacoustic therapy, and rhythmic auditory stimulation. The review aims to determine whether or not different brain stimulation approaches rely upon a similar physicochemical sequence of actions. The study identifies releva [...]

One of the objectives of psychological intervention is to help patients manage their emotions effectively by providing them with the necessary skills to accompany their own emotional states. To this regard, there seems to be a current lack of therapeutic resources aimed at helping patients assimilate and regulate emotions. This article proposes the application of a new technique which incorporates mindfulness, building on the premises of the model of psychological flexibility which defines "mindfulness" as a practi [...]
