The plane figure is compulsory mathematics material at all levels of education, including junior high school. However, students still make frequent mistakes in understanding the figures' properties. In this topic, must have skill to think critically. Critical thinking a process rational before deciding or taking action more specific direction. Therefore, study aims determine students' skills de...

It has recently been shown that superconductivity in magic-angle twisted trilayer graphene survives to in-plane magnetic fields are well excess of the Pauli limit, and much stronger than critical bilayer graphene. The difference is surprising because bilayers trilayers both support flat bands thought be fountainhead superconductivity. We show here can traced a $\mathcal{C}_2 \mathcal{M}_{h}$ sy...

in recent years, the application of composite materials in aircraft and space vehicle structural components has become increasingly popular. preventing failure of composite structural systems has been an important issue in engineering design. due to the lack of through-the-thickness reinforcement, structures made from laminated composite materials and adhesively bonded joints are highly suscept...
