Determination of Physiological and Harvest Antioxidant Activities of Sunflower Plants Growing in Alkaline Soils with DPPH Method

Various methods are employed to evaluate the antioxidant capacities of herbal products and foods. In this study, sunflower widely cultivated in Tekirdag region, Tunca MR(5580) sunflower variety grown in the alkaline soils of the Banarli Village in the Hayrabolu County and antioxidant activities of sunflower plant seeds during physiological and harvest periods were researched. It was compared with Butylated Hydroxy Toluene (BHT), a synthetic antioxidant, which is widely used in the food industry. Antioxidant activity was determined by DPPH method. Free radical scavenging activity of methanol extracts of sunflower was measured by 1,1-diphenyl-2-picryl-hydrazyl using the method. All analysis was run in triplicate and averaged. Physiological period of the examples in the antioxidant activity of 28 %, while in the period of harvest activity as 25 %.Namik Kemal University Scientific Research UnitNamik Kemal University [NKUBAP.00.M6.AR.11.01]The project with the number NKUBAP.00.M6.AR.11.01 titled as Research of Antioxidant Capacity of Sunflower (Helianthus Annuus) Seeds Cultivated in Tekirdag Region has been funded by Namik Kemal University Scientific Research Unit

Cross section and longitudinal single-spin asymmetry ALA_L for forward W±→μ±νW^{\pm}\rightarrow\mu^{\pm}\nu production in polarized p+pp+p collisions at s=510\sqrt{s}=510 GeV

International audienceWe have measured the cross section and single-spin asymmetries from forward W±→μ±ν production in longitudinally polarized p+p collisions at s=510  GeV using the PHENIX detector at the Relativistic Heavy Ion Collider. The cross sections are consistent with previous measurements at this collision energy, while the most forward and backward longitudinal single spin asymmetries provide new insights into the sea quark helicities in the proton. The charge of the W bosons provides a natural flavor separation of the participating partons

Highlights from the PHENIX experiment

International audiencePHENIX has performed an extensive study on the evolution of medium effects from small to large systems. PHENIX has continued searching for Quark-Gluon Plasma (QGP) in small systems by measuring collectivity, modification of light hadron and quarkonia production, and jet substructure. In large systems, detailed studies on the property of the QGP have been done using direct photon, $\pi^{0}$-hadron correlation, heavy-flavor electron, and $J/\psi$ flow with a large statistics of data collected in 2014. This report covers new results from the PHENIX experiment in various collision systems
