This paper studies and characterizes a solar collector with spherical geometry to produce hot water for sanitary and domestic applications and other facilities. The new geometry enlarges the solar collector surface and allows full sun tracking during the day without needing a solar tracking system. Although this geometry has been in use for some time, its market penetration is low due to the lack of perfect knowledge of solar collector behavior and the benefits compared with conventional solar collectors. The studi [...]

For wind-wave interaction studies, from the literature, two criteria for the wind sea are used: one is the wave age and the other wave steepness. Analysis of pertinent datasets from a data buoy near the passage of Hurricane Matthew in 2016 indicates that CpU10 = -15 HsLp + 1.3. Here CpU10 is the wave age and HsLp is the wave steepness, where Cp is the phase speed of the peak wave, U10 is the wind speed at 10 m, Hs is the significant wave height, and Lp is the peak or dominant wave length. It is found that 87% of th [...]

Acute rejection (AR) is one of the main predictors of long-term survival of allograft. The development of noninvasive diagnostic biomarkers of AR is an unmet need for the timely detection. This study aimed to identify novel detective biomarkers of AR by analyzing the urine proteome profile of transplant patients. Forty-two transplant patients including 30 biopsy-proven AR patients (including antibody and T-cell mediated rejection) and 12 transplant patients with stable renal function (control group) were enrolled.

Non-communicable diseases (NCDs) are responsible for two-thirds of premature deaths in Europe. This added to the European socio-economic scenario already weakened by the vital aging of the population, contributes to the loss of active individuals, weakening competitiveness and social and economic sustainability, thus making the prevention of NCDs a European objective. Preventing NCDs with the enrichment of the food environment using algae or their compounds, which are rich in nutrients and bioactivities, is an exce [...]

The urgency to manage global methane emissions has been acknowledged with international pledges to reduce 2020 levels by 30% by 2030. Carbon management requires effective tools to monitor changes, including those from significant sources including waste disposed on land. The first order degradation model used to determine landfill methane emissions, has been described by researchers as highly variable, insensitive and inadequate, despite recent attempts to explain microclimate impacts on methane oxidation.

Cystic fibrosis (CF) is a genetic disorder that significantly impacts respiratory function, leading to progressive lung damage and ultimately respiratory failure. Lung transplantation (LTx) is a critical intervention for CF patients with end-stage lung disease, offering improved survival and quality of life. Pulmonary rehabilitation (PR) plays a pivotal role both preoperatively and postoperatively in optimizing outcomes for LTx candidates and recipients. Pre-transplant PR interventions, including exercise programs, [...]

Tomato (Solanum lycopersicum L.) is the largest vegetable crop produced and consumed in the world. Tomatoes are a top source of Vitamin A and C, contain more dietary fibre, beta-carotene, iron, lycopene, magnesium, niacin, potassium, phosphorus, riboflavin, and thiamine. Tomatoes have a limited shelf life in ambient conditions and are highly perishable. It creates glut during the production season and becomes scanty during the off-season. Short shelf life, coupled with inadequate processing facilities results in he [...]

Epilepsy, a prevalent neurological disorder, affects more than 50 million individuals worldwide and is characterized by recurring seizures. Nonsynonymous single nucleotide polymorphisms (nsSNPs) found within coding regions of epilepsy-related genes are believed to have significant impacts on protein function. This is due to their tendency to cause mutations in the encoded amino acids, which can subsequently lead to pathogenic alterations in protein structure and function. Consequently, nsSNPs have the potential to [...]

While it may seem intuitive to suggest that compassion aids in the healing process, there is actual evidence to support that compassion changes physiology, which in turns affects emotional and physical healing. The focus of this opinion paper is on the use of compassion between health care providers and patients based on the use of compassion in the mental health field. Not only do patients benefit from compassion, but health care providers may also benefit. Creating compassionate relationships with patients may [...]

Disperse porous Mn-doped ZnO-ZrO2 nanocomposites were prepared using the facile polymer-salt method. The effect of Mn content on the crystal structure, composite morphologies, their ability to photogenate the singlet oxygen, luminescence properties, and bactericidal activities were studied. The crystal structure and morphology of these materials were investigated using XRD and SEM analysis. It was found that obtained nanocomposites consist of small (~9 nm) hexagonal ZnO and fine ZrO2 crystals and the embedding of M [...]
