Isoxazole derivatives of alpha-pinene isomers: Synthesis, crystal structure, spectroscopic characterization (FT-IR/NMR/GC-MS) and DFT studies
(ELSEVIER SCIENCE BV, 2016)
In this paper, the alpha-pinene isoxazole derivatives (3a-b-c, 4a-b) were synthesized via 1,3-dipolar cycloaddition and characterized with FT-IR, H-1 NMR, C-13 NMR and GC MS. Isoxazole (C21H23NO) compound (4a) 6,6,7a,-tr ...
Determination of experimental, analytical, and numerical values of tool deflection at ball end milling of inclined surfaces
(SAGE PUBLICATIONS LTD, 2016)
The deflections appeared by cutting forces in ball end milling of inclined surfaces can result in defects in workpiece. Finding deflection values has a significant importance for keeping the production within the appropriate ...
Influence of modified intended use on the seismic behavior of historical himis structures
