In this formula, "A," is, again, the area, "r" represents the radius (half the distances from one side of the circle to the other), andπis a Greek letter pronounced "pi," which is 3.14 (the ratio of a circle’s circumference to its diameter). Practical Applications There are many...
While using real objects in teaching and learning pi with nine university preservice teachers (PSTs) of Mathematics, the teaching and learning processes were framed under the lens of social constructivist perspective (Vygotsky, 1978). Individual PSTs constructed mathematics and elaborated their ...

The main challenge is the fact that turbulence is a multi-scale phenomenon in both time and space. The energy is mainly transferred from the largest to the smallest scales of the flow, where it is dissipated5, although there is also an energy path in the opposite direction17. There are se...
Accentuated sympathetic nerve activity (SNA) is a risk factor for cardiovascular events. In this review, we investigate our working hypothesis that potentiated activity of neurons in the rostral ventrolateral medulla (RVLM) is the primary cause of experi

Computer programming takes part in both science/engineering and mathematics (as distinct from computer science, which is a branch of mathematics). We spend most of our time debugging, which is just the application of the scientific method: form a hypothesis about the bug, make a fix, test it...
We consider importance sampling as well as other properly weighted samples with respect to a target distribution $\pi$ from a different point of view. By considering the associated weights as sojourn times until the next jump, we define appropriate jump
in producing the natural bioactive products and using to biocontrol of plant pathogens. These fungi can be used to produce natural drugs, biopesticides, and biofertilizers that lead to decrease the dangers of synthetic chemicals. This can save the ecosystem and reduce the chemical residue in the ...
