The fully fuzzy linear programming (FFLP) problem has many Flea different applications in sciences and engineering, and various methods have been proposed for solving this problem.Recently, some scholars presented two new methods to solve FFLP.In this paper, by considering the L-R fuzzy numbers and the lexicography method in conjunction with crisp

We investigate a nonautonomous two-species competitive system with stage structure and double time delays due to maturation for two species, Collections where toxic effect of toxin liberating species on nontoxic species is considered and the inhibiting effect is zero in absence of either species.Positivity and boundedness of solutions are analytica

The COVID-19 pandemic is impacting on the mental health of the general population and its consequences will be long lasting.As already noted in previous epidemics, different factors can moderate the CAL/MAG 2:1 detrimental impact of a traumatogenic event on mental health.In particular, it has been found that people using problem-solving coping stra

IntroductionThe significance of mental health and its impact on overall well-being is increasingly acknowledged across various sectors, including higher education.However, despite this growing recognition, the stigma associated with mental health issues and related help-seeking, particularly Polycarbonate within certain cultural groups and socio-ec

Abstract There is growing interest in materials that exhibit enhanced proton conductivity at 12V Kettle elevated temperatures without the need for humidification.Here, we develop a dendritic proton-conducting dopant for proton exchange membranes based on phytic acid (PhA) salts.PhA, which contains six phosphate groups capable of facilitating proton
