A derivation of the relation between the vacancy formation energy E,, the migration energy E, and the Debye temperature 0c is presented. In the Debye model, the relation between E, and Bc follows directly from the “dynamical” form of diffusion theories. The relation between E, and Bc is obtained for solids obeying a corresponding states law. The Debye temperature appearing in the derived expres...

In this study some new compounds have been prepared including thereaction of diazoium salt 1,4-phenylenediamine with 2-mercaptobenzaldehyde at (0-5)0C[F1]. Then Schiff bases [F2-F6] werethen synthesized through the reaction compound [F1] withsubstituteds aniline in absolute ethanol, and were convertedinto 2,3 - dihyroquinazolin 4(1H) one derivatives [F7-F11] by 2-amino benzoic acid ethanol. The...

Shell and Helical Tube Exchanger merupakan salah satu alat penukar kalor dengan memanfaatkan 2 pipa yaitu bagian luar dan dalam (Helical tube). Fluida panas mengalir pada dalam, fluida pendingin berlawanan arah (Shell), sehingga terjadi proses yang di dari dipindahkan ke dingin mengalir. Proses ini berjalan terus menerus. Penelitian bertujuan untuk mengetahui kinerja shell helical tube heat exc...

It takes three weeks to analyze the germination percentage of Arabica coffee seeds germinated using paper and a three-day water-soaking method. This 3- week period is considered too long for seed distribution remote areas. Thus, we need modify this test needs be modified have shorter time. Temperature treatment one method break dormancy faster germination. study aimed obtain more precise on see...

We report the theoretical and experimental study of a temperature sensor based on the changing of the refractive index with the temperature in double core optical fibre. Because of it the coupling coefficient between two cores depends on temperature. This sensor uses the double core fibre directly as a temperature sensor as well to a data transmission. The influence of variations of the tempera...
