Reflection emotions based on different stories onto EEG signal

Abstract: Objective of this study was to investigate reflection of emotions based on different stories onto EEG. EEG data that used in this study have been acquired from database University of California San Diego. EEG signal was filtered to frequency range that contain important sub-bands of EEG by using discrete wavelet transform to analyze reflection of emotion based on different stories onto EEG. Power spectrum estimation of EEG that filtered to related frequancy range was obtained by using Burg method. Diffrerent power spectrum densities onto EEG signal were obtained for each different emotions based on different stories. There are similar studies in literature and results that were obtained in this study support the similar studies.

Investigation of the effects of a carbon-fiber tabletop on the surface dose and attenuation dose for megavoltage photon beams

Abstract: Background: Mul ple beams are generally used with an increased possibility that the beam axis intersects the treatment table. Treatment tabletops are commonly made of carbon fiber due to its high mechanical strength and rigidity, low specific density, extremely light and low radia on beam a enua on proper es. Purpose of this paper is inves gated the dose changes in the buildup region and beam a enua on by a carbon fiber tabletop for high energy 6and 18-MV photon beams. Materials and Methods: Measurements were performed for 10 cm × 10 cm and 20 cm × 20 cm field sizes. The surface dose and percentage depth doses (%DD) were measured by a Markus parallel plate chamber at a source-surface distance (SSD) of 100 cm for 6 MV and 18 MV photon beams. A enua on measurements were made at the solid-water phantom for gantry angles of 0 and 180 rota on of the beam. Results: A carbon fiber tabletop increases the surface dose from 12.87% to 86.65% for 10 cm x 10 cm and from 8.72% to 71.16% for 20 cm × 20 cm field at 6 and 18 MV, respec vely. The surface dose with the carbon fiber tabletop in an open field (0) increases with field size. Conclusion: The carbon fiber tabletop causes a substan ally increased surface dose, and also significantly decreases the skin-sparing effect, which is clinically important. The dosimetric effect of the tabletop may be higher, especially for the intensitymodulated radia on therapy depending on the beam orienta on.

Measuring of the Genotoxic and Potential Antioxidant Effects of Essential Oil Obtained from Satureja Hortensis Against to Phaseolus Vulgaris

Abstract: It is known that, there are many ways for increasing the yield at the crops specially cereal products. Genetic manipulations and physiological interventions are the primary studies that aim to obtain products at high quality and amounts. It is known that, the usage of synthetic chemicals for physiological inverventions negatively affects organism. But using natural plant products instead of these chemicals is a subject that draws attention of today scientific environment. In this study, this situation was taken into consideration and the essential oil obtained from Satureja hortensis (SEO) plant were applied to bean seeds. The genotoxic and physiological effects of SEO at four different dosages were detected against to Phaseolus vulgaris seedlings. According to obtained data, essential oil that were applied at different doses decreased the genomic stability of the bean seeds up to 30.77% in accordance with the increased dosage. The essential oil applied in the same way lead to stress on enzyme activities of seedlings. Among the antioxidant enzymes, while, significant changeswere observed at Superoxide dismutase and Peroxidase enzymes according to the control, no significant change was seen at Ascorbate peroxidase level.
