  • What Are The Advantages Of Restorative Materials

    828 Words  | 4 Pages

    The choice of restorative material is considered to be one of the most important factors for the success and reliability of any restorative system. Composite resin gained popularity among clinicians due to its ease of handling, excellent esthetic and mechanical properties, and reported ability to reinforce weakened dental structure. (73) However, when a cavity preparation exceeds the recommended limits for the direct application of composite resins, indirect total- or partial-coverage restorations

  • The Importance Of Chromatography In Forensics

    1298 Words  | 6 Pages

    An organic solvent or a mixture of solvents (the eluent) flows down through the column. Components of the sample separate from each other by partitioning between the stationary packing material (silica or alumina) and the mobile eluent. Molecules with different polarity partition to different extents, and therefore move through the column at different rates. The eluent is collected in fractions. Fractions are typically analyzed by thin-layer chromatography

    Total Internal Reflection: The light passes through the fibre by the process of total internal reflection. In this process the light is contained within the glass core and cladding by careful designing of their refractive indices. So the light passes through the fibre by reflecting the escaping light at the glass core because of its lower refractive index and this reflection makes it possible to pass the light with low loss. This phenomenon is termed as Total internal reflection. [33] How it is made:

  • Heat Transfer Case Study

    8.1.5 heat transfer in nucleation boiling In the heat transfer, the 3 temperature is needed. It is wall temperature, Tw, saturation temperature, Tsat, liquid temperature, TL. To determine the heat transferred coefficient, the wall temperature must minus to the saturation temperature (Tw - Tsat). The heat transfer is interrelated driving temperature contrast, refer equation [15 – 20] below [40]. q^''=c_1 〖(T_w- T_sat)〗^m {15} q^''=h(T_w- T_sat) {16} h= c_2 〖(T_w- T_sat)〗^(m-1) = c_2 〖(T_w- T_sat)〗^n
