Several cases of the explanation of the phenomenon of standing waves in strings, there are few experimental measurement tools when demonstrating this phenomenon in a classroom, it is for this reason that we have implemented different forms to show ho

Teaching by direct models in science has been weakening the learning process of the students, because the real problems in engineering are not solved by direct models instead commonly they are solved by inverse models. On the other hand, one of the m

The presence of trace elements in fuels with high vapor pressure, such as diesel oil, can cause several problems, such as the poisoning of automotive catalysts and environmental pollution; thus strict quality control is required. Despite its high dig
