The effect of a glyphosate-based herbicide on acetylcholinesterase (AChE) activity, oxidative stress, and antioxidant status in freshwater amphipod: Gammarus pulex (Crustacean)
No full textThis study had determined the effect of glyphosate-based herbicide (GBH) on acetylcholinesterase (AChE) enzyme activity, oxidative stress, and antioxidant status in Gammarus pulex. Firstly, the 96-h LC50 value of glyphosate on G. pulex was determined and calculated as 403 μg/L. Subsequently, the organisms were exposed to sub-lethal concentrations (10, 20, and 40 μg/L) of the determined GHB for 24 and 96 h. The samples were taken from control and GBH-treated groups at 24 and 96 h of study and analysed to determine the malondialdehyde (MDA) and reduced glutathione (GSH) levels, the AChE, superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) enzyme activities. In the G. pulex exposed to GBH for 24 and 96 h, the MDA level increased significantly (p < 0.05). The GSH level, the AChE, the CAT, and the GPx activities decreased compared with the control group (p < 0.05). G. pulex exposure to GBH for 24 h showed a temporary reduction in the SOD. GBH exposure led to oxidative stress in the G. pulex as well as affected the cholinergic system of the organism. These results indicated that the parameters measured may be important indicators of herbicide contamination in G. pulex
Müzik, gelenek ve temsil
No full textAnadolu insanının farklı bölgelerde ürettiği müzik ve inanç sistemlerinin toplumsal ve geleneksel yaşamla olan ilişkisinin anlaşılabilmesi, bugün hızla değişerek ayrıntıların ve farklılıkların önemsizleştiği, müzikal beğenilerin aynılaştığı bir dünyada bizlere kim olduğumuz ve nereden geldiğimize dair bir düşünce zemini kazandırmaktadır. Anadolu kültür havzasında binlerce yıllık geçmişi olan ve bugün Sivas’ta olduğu gibi, ülkemizin pek çok bölgesinde hem folklor hem de müzikal anlamda ortak bir hafızaya dayalı olarak paylaşılan davul zurna kültürü ise ifade ettiği müzik ve etrafında bütünleşen pratiklerle birlikte düşünüldüğünde insanımıza dair pek çok tecrübeyi anlamamıza yardımcı olmaktadır. Sivas’ta yürütülen ve yaklaşık 4 yıl süren bu çalışmanın fikrî temellerinin de böyle bir tasavvurla filizlendiğini belirtmek isterim

Gammarus pulex as a Model Organism to Assess the Residual Toxicity of Slaughterhouse Wastewater Treated by Electrocoagulation Process
No full textIt was assessed the efficiency of the electrocoagulation (EC) in slaughterhouse wastewater (SW) treatment by using antioxidant parameters of Gammarus pulex. The SW was treated by EC. Superoxide dismutase (SOD), glutathione peroxidase (GPx) and catalase (CAT) activities and malondialdehyde (MDA) levels in G. pulex exposed to pre- and post-treated of the SW during 24 h and 96 h were analysed. Standard methods were applied during the analysing process of the physicochemical quality parameters for both untreated and treated SW. All measured physicochemical parameters were decreased following
the treatment process via EC. After the treatment process, it was observed that while SOD activities and MDA levels were decreased, CAT activities were increased and GPx activities did not exhibit any change. In conclusion, the present study demonstrated the abilities of untreated SW to promote oxidative stress in model organism. The SOD, CAT activities and MDA levels in G. pulex revealed that EC process were efficient in the SW treatment
An ethnobotanical survey of medicinal plants in Karlıova (Bingöl-Turkey)
No full textThis study aims to identify wild plants collected for medical purposes by the local people of Karlıova District located in the Eastern Anatolia region of Turkey and to determine the uses and local names of these plants. A field study had been carried out for a period of approximately 4 years (2013–2016). During this period, 99 vascular plant specimens were collected. Among them, 91 species are wild and 8 species are cultivated plants. Demographic characteristics of participants, names of the local plants, their utilized parts and preparation methods were investigated and recorded. 99 plants were found to be used for medical purposes before in the literature analysis of the plants used in our study, while 9 plants were found to have no literature records. In Turkey, local plant names display differences especially due to local dialects. The plants used in Karlıova are known by the same or different local names in various parts of Anatolia. In the research area, local people were found to use 99 plants from 26 families for curative purposes. The medicinal uses of Stenotaenia macrocarpa Freyn & Sint., Inula helenium L., Scorzonera incisa DC., Tripleurospermum caucasicum (Willd.) Hayek, Astragalus chamaephaca Freyn, Geranium libanoticum Schenk, Rhinanthus serotinus subsp. aestivalis (N.W.Zinger) Dostál, Verbascum songaricum Schrenk. and Bunium elegans (Fenzl) Freyn that we found were used in our study area and recorded for the first time. These plants, used for the treatment of various diseases, are abundantly found in this region. Drying of the medicinal plants enabled the local people to use them in every season of the year

Bu araştırmada Millî Eğitim Bakanlığına bağlı okullarda görev yapan özellikle baby boomers ve X kuşağı öğretmenlerinin dijital entegrasyon uyumlarının incelenmesi amaçlanmaktadır
Predicting potential links by using strengthened projections in evolving bipartite networks
No full textThe link prediction problem can be used for predicting the link changes that are difficult to understand and costly in network science. So far, many different models have been proposed to predict links in the network. Most of the proposed models in the link prediction have focused on the unimodal networks. In this paper, we present a link prediction model that attempts to predict links in the large-scale bipartite networks. The proposed method consists of two stages: The first stage is the extraction of the potential link set. A limitation of the previous works that addressed the link prediction problem in bipartite networks is that only the structural properties of the projected networks that were transformed from the bipartite networks are used to extract the potential links. In this paper, in addition to the structural properties of the projected networks, we take into account the structural properties of the bipartite network. Also, we employ the strengthened projection network model instead of the classical projection network models. The second stage is the calculation of prediction score of each potential link. The classical proximity measures have several disadvantages in dynamic complex networks. When network evolution that considers valuable information between node pairs are ignored, the potential information source is not efficiently used in the link prediction. Therefore, in this stage, we propose a time-aware proximity measure based on social network evolution, instead of classical proximity measures using the current state of the network. To the best of our knowledge, this is the first effort that considers the evolution in bipartite networks. To test the performance of the proposed method, we made some experiments on two real networks that have different frame size. Experimental results show that the success of our method is promising

Assessment of the mass attenuation coefficients of granite, basalt, andesite and tuff stones with the Geant4 model of a high-purity germanium detector
No full textIn this work, the radiation shielding properties of various natural stones, such as granite, basalt, andesite and tuff, were determined by using Monte-Carlo simulations performed with the Geant4 model of a high-purity germanium (HPGe) detector. Mass attenuation coefficients were calculated for γ -ray energies of 80.9, 140.5, 356.5, 661.6, 1173.2 and 1332.5 keV and for the sample thicknesses between 1 and 7 cm. The results of this study indicate that the stone samples have lower mass attenuation values varying in the range from −28.8% to −3.7% compared to lead. Among the measured stone samples, the mass attenuation values of tuff stone are closest to lead (above 661.6 keV)
