Many sensible heat storage materials are regularly used as thermal energy storage (TES) systems to improve the efficiency of solar dryers. The present work focuses on the effects of the volume and particle sizes of a volcanic stone (pozzolan) for the same purpose. Samples soaked in matt black and without soaking were also considered. Heat charge and discharge tests were carried out by exposing the pozzolan contained in a solar collector of the direct solar dryer (DSD) and indirect solar dryer (ISD) to the sun. Char [...]

One of the major hurdles still facing the field of transplantation is the management of immunosuppression and the morbidity that results from treatment. Due to toxicity and complications from a maintenance immunosuppression therapies, a necessary improvement in post-transplant immunosuppressive therapies must be the development of a low-side effect therapy. Cell-based therapies as an emerging candidate offer a novel approach to generating graft tolerance, and when utilized within a combination therapeutic strategy, [...]

Lesbian, gay, and bisexual (LGB) older adults may be more vulnerable to elder abuse (EA) due to prior marginalization and trauma, lifelong discrimination, and health disparities. While characteristics of both victims and perpetrators can modify the risk for EA, few studies have focused on perpetrators. This study examined the number and type of perpetrator-victim relationships and perpetrator profiles for EA experienced in the prior year, by abuse type and sexual orientation and gender identity of the abused. Data [...]

Pancreatic islet transplantation represents an effective therapy with lower morbidity for patients carriers of type 1 diabetes compared to whole pancreas transplantation. Although complete insulin independence is usually not achieved it allows control of glycemia balance reducing the risk of severe hypoglycaemia events and impaired awareness of hypoglycaemia. Recent trials had demonstrated islet transplantation to be more effective than current medical treatment and improvements in outcomes also have been reported [...]

In a pioneer transcontinental pilot study conducted with 50 volunteers, it was revealed that women could have apparently overcome the world's toughest lockdown in terms of changes in the general state of health measured using the heart rate variability parameter better than men. The results of the present study obtained in Wuhan provide information on the initial trend in this regard.

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 article discusses the findings from a training programme called ‘Communication and Interaction Training’ (CAIT). CAIT was designed to improve the confidence of carers in their use of communication skills with people living with dementia, particularly when managing behavioural agitation. This pre/post assessment study employed a mixed design, and showed positive effects in terms of quantitative and qualitative features. The participants were mainly from a specialist team who were experienced in managing episode [...]

In modelling studies targeted MRI (tMRI) of small increases in the T1 of tissues using divided Subtracted Inversion Recovery (dSIR) sequences show ten or more times the contrast seen with conventional IR sequences. This may be particularly useful in imaging normal appearing white matter where there may be small changes in T1 and/or T2 in disease but these changes may be insufficient to produce useful contrast with conventional T2-weighted spin echo (T2-wSE) and T2-FLuid Attenuated Inversion Recovery (T2-FLAIR) sequ [...]

This editorial briefly discusses the issue of potential toxicity in the case of long-term photobiomodulation (PBM). Scientific articles from PubMed, Google Scholar, and the China National Knowledge Infrastructure were included in a heterogeneous search. There have been very few studies on the long-term effects of PBM, as well as its potential toxicity. There is no evidence that PBM is toxic when used at therapeutic or imaging doses. There are no such concerns with intracranial PBM application (e.g., optical fiber) [...]

Carbon management is imperative to curb global temperature increases and mitigating climate change impacts. This report explores the carbon management strategies employed by Diebold Nixdorf, a multinational financial and retail technology company. As of 2021, the company has not established specific reduction targets and has not committed to achieving net zero emissions. The company employs diverse carbon reduction strategies, such as carbon offsetting, solar energy, and fleet improvements, with notable projects li [...]
