This study aims to analyze factors related public health promotion behavior during the COVID-19 pandemic. research method is observational analytic using a cross-sectional design. The results showed that majority of respondents had good knowledge 64.85, positive attitude 67.65, high motivation 88.6%, family support 84.8%, and 75.2%. chi-square test shows (P-value 0.003), 0.001), 0.004), while n...

We develop a model for stochastic pre-enrichment and self-enrichment in globular clusters (GCs) during their formation process. GCs beginning their formation have an initial metallicity determined by the pre-enrichment of their surrounding protocloud, but can also undergo internal self-enrichment during formation. Stochastic variations in metallicity arise because of the finite numbers of super...

In this paper, we have proposed and analyzed a simple model of Influenza spread with an asymptotic transmission rate. Existence and uniqueness of solutions are established and shown to be uniformly bounded for all non-negative initial values. We have also found a sufficient condition which ensures the persistence of the model system. This implies that both susceptible and infected will always c...
