Chickenpox or varicella is an infectious disease caused by the varicella-zoster virus V Z V . This virus is the cause of chickenpox (usually a primary infection in the nonimmune host) and herpes zoster. In this paper, a compartmental model for the dynamics of V Z transmission with the effect of vaccination is solved using the A B C fractional derivative. The possibility of using the fractal dimension as a biomarker to identify different diseases is being investigated. The problem is investigated in two different levels of research using two scale dimensions. To ascertain the existence and uniqueness of the solution, we qualitatively evaluate the model. We have used the Euler method to compute the numerical solution for the system. At the end, we provide the graphical results showing the effectiveness of two-scale dimension and fractional calculus in the current model.

The purpose of the study was to investigate the factors that affect the low performance of senior high school students in Integrated Science in the Tamale Metropolis. Concurrent triangulation mixed methods design was used. The instruments used during data collection were questionnaires and interview guide. A multistage sampling process was used to select four hundred students and fifteen teachers who teach Integrated Science. Data collected was analysed using exploratory factor analysis and thematic content analysis. The study revealed three factors: school environmental factor, teacher attitude and student attitude as contributors to students’ low performance in Integrated Science. It is, therefore recommend that the education ministry should provide a comfortable learning environment for effective teaching and learning to improve students’ performance in Integrated Science.<p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0541/a.php" alt="Hit counter" /></p>
