Study on the SUAM Double Magnet System for Polishing

Superconductive assisted machining (SUAM) is a novel machining method that eliminates tool interference via magnetic levitation tools. In our study, we developed a double magnet system (DMS) to increase the maximum power of the holding force and stabilize the magnetic rotation during polishing via the higher magnetic flux compared to a single magnet system (SMS). The maximum magnetic flux density of the DMS was approximately 100 mT higher than that of the SMS. In these cases, the entire holding force increases as the distance between the superconducting bulk and lower magnet decreases. The attractive forces are maximum around a displacement of 6 mm, although the repulsive and restoring forces increase spontaneously. The polishing performances of the DMS on the SUS304 and A1100P plates were evaluated using water-based diamond slurries, for equal levitation amounts. The amount removed by the DMS increased for the A1100P and SUS304 substrates compared to that by the SMS. In this case, we observe that the deviation of the polishing area on the DMS decreases compared to that of the SMS, reflecting a more stable rotation and movement due to the higher holding force.

Study of Magnetic Rotation in 193Pb: An Example of Collaboration Between Southeastern European Research Teams

This paper summarizes the results of a series of experimental studies of mag­netic rotation in mid-shell Pb nuclei. The focus is for the 29/2- v(1i^3/2)^{-1} (x) π(3s1/2)^{-2}(1h9/2)(i13/2) magnetic band in 193Pb, for which all experimental observables have been measured. This provides a stringent test of the theoretical models aiming at the description of such excitations. These studies have been carried out in col­ laboration with different research teams from the Balkans and are an example how to utilize most efficiently the huge scientific potential of the region.

GC-MS Analysis of European Mistletoe (Viscum album L.) Plant Grown at Syrian Coastal Area

In this study, efforts were made to isolate phtochemicals from European mistletoe (Viscum album L.) using hot (Soxhlet) and cold (magnetic rotation) extraction methods. The dried Viscum album L. (10 g) were extracted exhaustively by Soxhlet with methanol and dichloroethane solvents. Subsequently, 1 μL of sample was utilized for GC/MS analysis, which exhibited 50 peaks of phytoconstituents in the range of 0.12-22.04%. The highest flavonoids content was determined using quercetin calibration curve having a value of 62.26 mg QE/g dry weight.
