Öğe Alleophatic effects of benzoic acid, salicylic acid and leaf extract of Persica vulgaris Mill. (Rosaceae)(Elsevier Science Bv, 2017) Ozpinar, H.; Dag, S.; Yigit, E.Secondary compounds in higher plants have great diversity in terms of biologic activity. Most of them are used for the defense by plants. This study aims to investigate the effects of benzoic acid, salicylic acid, and Persica vulgaris Mill. (Peach) on the germination of the seeds of cultivated plants such as Triticum aestivum L. (wheat), Zeamays L. (corn), Cicer arietinum L. (chickpea), as well as weeds such as Lepidium campestre (L.) R. Br. and Convolvulus arvensis L. Method 1, in which benzoic acid, salicylic acid, and Persica vulgaris Mill. are added to the germination environment at different doses, and Method 2, in which they are mixed with the irrigation water at the specified doses, have been employed in this study. As a result of this study, it has been determined that the leaf extract of P. vulgaris Mill., Benzoic acid, and salicylic acid prevent the growth of the root and stem in all seeds at high doses in both methods, and they increase the growth at low doses. According to the GC-MS results of the leaf extract of P. vulgaris Mill., benzoic acid has been determined to be at the highest rate. No difference has been found between months as a result of the HPLC analysis of the amounts of benzoic acid. The determination of negative effects of benzoic acid, salicylic acid, and peach leaf extract both on cultivated plants and weeds at high doses will repress the development of cultivated plants as well as weeds. Growing cultivated plants in places with peach trees may decrease the yield. The leaves should not be let decompose on the soil in defoliation season, and fallen leaves should be collected. Not collecting all of the leaves and leaving some of them may increase the development of weeds in the surrounding area since it may cause a low dose effect. (C) 2016 SAAB. Published by Elsevier B.V.

O.; Goren-Saglam, N.; Torun, H.; Yigit, E.; Unal, D.High temperature stress is a major environmental stress factor for all photosynthetic organisms. Some lichen species could have the ability of tolerance against global warming. In the present study, we investigated the effects of high temperature on GABA metabolism in two different lichen species Evernia prunastri and Usnea sp.. Evernia and Usnea sp. were collected from unpolluted locations in Bilecik, TURKEY. Evernia and Usnea sp. were kept at 45 degrees C for 0, 24 and 48 h. We analyzed GABA content, glutamate dehydrogenase (GDH) and glutamate decarboxylase (GAD) activities and also chlorophyll and MDA contents in the thalli of the lichens. The chlorophyll degradation and lipid peroxidation data indicated that E. prunastri thalli showed tolerance to high temperature while Usnea sp. thalli were found to be sensitive under these conditions. GABA content was enhanced by high temperature stress in E. prutastri thalli, while GAD and GDH activities were decreased. According to our results, we can suggest that GABA accumulation in lichen thalli could occur via different metabolic pathways.Öğe Investigating the Knowledge, Attitudes and Behaviours of Parents Regarding Vaccine Rejection(Oxford Univ Press, 2020) Gokce, A.; Yigit, E.; Gungor, A.; Aslan, M.; Ozer, A.[Abstract Not Available]Öğe Knowledge and Behavior of Nurses on Childhood Vaccine Refusal in a Hospital of Eastern Turkey(Oxford Univ Press, 2020) Boz, G.; Yigit, E.; Gokce, A.; Aslan, M.; Ozer, A.[Abstract Not Available]Öğe Knowledge, Attitudes And Behaviors Of Faculty Members On Childhood Vaccine Refusal A University(Oxford Univ Press, 2020) Yigit, E.; Boz, G.; Gokce, A.; Aslan, M.; Ozer, A.[Abstract Not Available]Öğe The Use of Pistachio Pollen for the Production of Nanostructured Porous Nickel Oxide(World Scientific Publ Co Pte Ltd, 2018) Atalay, F. E.; Yigit, E.; Biber, Z. S.; Kaya, H.Natural biotemplates - such as bacteria, fungi and viruses - are used in nanostructured metal oxide production. The pollen can be found abundantly in nature, and their microcapsules can be easily isolated from the pollen by chemical treatments. To date, pollen microcapsules are mostly used as drug carriers and catalytic agent templates. In the present study, nanoporous-structured nickel oxide is produced using Pistachio pollen microcapsules. The raw pollen, chemically treated pollen and metal-coated pollen were characterized using scanning electron microscopy, Brunauer-Emmett-Teller (BET) surface area analysis, thermogravimetric analysis (TGA), differential thermal analysis (DTA) and X-ray diffraction (XRD) techniques. The natural Pistachio pollen which were procured from Gaziantep, Turkey, are spherical, with a diameter of approximately 23 mu m. The maximum surface area obtained for nickel oxide-coated microcapsules is 228.82 m(2)/g. This result shows that Pistachio pollen are an excellent candidate for the production of porous nanostructured materials for supercapacitor electrodes.
