Pancreatic islet transplantation (ITx) has moved from the experimental phase of development to a position of an accepted and appropriate procedure to apply in clinical medicine. The primary indication for use of ITx is for management of dangerous and recurrent hypoglycemia secondary to use of exogenous insulin for management of hyperglycemia in people with type 1 diabetes. ITx involves procurement of a pancreas donated by a person who has died. The organ is taken to a specialized laboratory for isolation of islets [...]

Social support has been shown to have many positive effects on our lives, health, and ability to grow and flourish. Lack, or diminished social support results in loneliness. This thematic review focuses on the elderly, and the loneliness that is part of the life of many of them. The review highlights the social connections and the expectations that the elderly may have of them, and how being connected to others may alleviate, loneliness. Loneliness is known to negatively affect one’s health, social life, familial r [...]

The primary objective of this study was to evaluate the efficacy of homeopathic medicines in the reduction or resolution of breast fibroadenoma (FA) through ultrasound (US) assessment in intervention and control groups. The secondary objective was to compare the efficacy of the homeopathic intervention in single and multiple fibroadenomas. A single-blind, randomized, placebo-controlled pilot study was conducted from January 2014 to June 2018 at 4 research centers with 6 months of follow-up. Females in the age group [...]

This article quantifies the recycling potential of the metallic materials that make up three-phase induction motors. The data on the use of electric motors by type and power determines that the most significant recycling potential lies in this low-voltage motor which powers up to 75 kW. The work aims to show the possibility of such recycling in the European Union (EU). The metals used to make the various parts of the induction motor and the main recycling methods that allow their reuse are listed. It evaluates whic [...]

Pregnancy and postpartum periods are known as sensitive periods in women’s life and COVID-19 pandemic seems to be worsening their mental health with major impacts on exclusive breastfeeding duration. Therefore, the present study aims to fill the gap in the literature by assessing the links between postpartum anxiety and depression symptoms and breastfeeding duration as well as the associated factors during the COVID-19 pandemic. A longitudinal prospective observational study was conducted between November and [...]

This research aims to model and compare two strategies for locating new hydrogen refueling stations (HRS) in a context of high uncertainty on H2 demand and on the spatial distribution of demand points. The first strategy S1 represented by an agent-based model integrating a particle swarm optimization metaheuristic consists of finding the best HRS locations by adapting to the real evolution of the demand. A second strategy S2 consists in solving a classical capacitated p-median problem based on H2 consumption foreca [...]

This study intends to determine the behavior of glass laminate aluminum-reinforced epoxy (GLARE) and glass fiber-reinforced polymer (GFRP) composites under a low-velocity impact test. Experimental tests and numerical simulations are considered for this investigation. All samples are made by the hand lay-up method. Moreover, specimens are produced with a 7075-T6 aluminium sheet with a 0.5 mm thickness, resin 3001, and E-glass fiber. The drop weight test performs the low-velocity impact at 6.7 J and 10 J impact energ [...]

Familial Mediterranean Fever (FMF) is classified as an autoinflammatory genetic disease inherited by mutations in MEFV. These mutations can affect the dysregulation of inflammatory processes in the human body and lead to fever and pain in the chest and abdomen. Many known missense mutations in MEFV are linked to FMF disease. Mutations in MEFV in most cases are located on the short arm of chromosome 16 and can impair the function of the pyrin protein. In this research, we aimed to examine the entire exons of MEFV fo [...]

The article aims at optimizing six-phase induction generator-based renewable energy systems (6-phase IGs or dual star induction generators) through a novel nonlinear optimal control method. Six-phase induction generators appear to be advantageous compared to three-phase synchronous or asynchronous power generators, in terms of fault tolerance and improved power generation rates. The dynamic model of the six-phase induction generator is first written in a nonlinear and multivariable state-space form. It is proven th [...]

This research study addresses certain theoretical issues surrounding the relationship between digital technologies, the aging population, and identity. At the same time, it offers a conceptual proposal of indicators of the social inclusion of older people in the digital culture of society as a potential starting point for further empirical research. The progressive trend of a growing proportion of older people is a demographic reality in many economically and technologically advanced societies. This demographic agi [...]
