YABANCI DİL OLARAK TÜRKÇENİN ÖĞRENİMİNDE KAYGININ AKADEMİK BAŞARIYA ETKİSİ

Kadir YOĞURTÇU | Gökçe YOĞURTÇU

Kaygı, bireyin varoluşsal etmenlerinden biri olarak ortaya çıktığı gibi çoğunlukla yaşadığı fizik ve sosyal çevre ile etkileşimleri ve deneyimleri sonucunda görülen intrapsişik (intrapsychic) durumları ifade etmekte kullanılan bir kavram olarak da karşımıza çıkmaktadır. Konu ile ilgili yapılan bilimsel araştırmalarda yabancı dil öğreniminde gözlemlenen kaygı türünün genel kaygı kavramlaştırmalarından ayrı tutularak değerlendirildiği gözlemlenmektedir. Söz konusu çalışmalara göre kaygı daha çok psiko-motor üretime dönük dinleme ve konuşma becerilerinde görülmekte, ayrıca iletişim korkusundan, s ...Более

Synthesis, characterization, and application of silver nanoparticle-thiophenol nanocomposite film on the glassy carbon surface

Ali Osman SOLAK

In this study, 4-thiophenol modified glassy carbon electrode was prepared by the reduction of 4-diazothiophenol tetrafluoroborate salt. Silver nanoparticles were attached to the thiophenol modified surface to prepare a thiophenol-silver nanoparticle composite film. 4-Aminothiopenol molecules were deposited by self-assembling technique to form multi-layered nanofilms of TP/SNP/PhNH2 on glassy carbon substrate. These surfaces were characterized by cyclic voltammetry, electrochemical impedance spectroscopy, X-ray photoelectron spectroscopy, reflectance-absorption infrared spectroscopy, and ellips ...Более

Biofuel Cell Based on Anode and Cathode Modified by Glucose Oxidase

Ali Osman SOLAK

A single compartment biofuel cell (BFC) based on an anode and a cathode powered by the same fuel glucose is reported. Glucose oxidase (GOx) from Aspergillus niger was applied as a glucose consuming biocatalyst for both anode and cathode of the BFC. The 5-amino-1,10-phenanthroline modified graphite rod electrode (GRE) with cross-linked GOx was used as the bioanode, and the GRE with co-immobilised horseradish peroxidase and GOx was exploited as the biocathode of the BFC. The open-circuit voltage of the designed BFC exceeded 450 mV and a maximal power density of 3.5 µW/cm2 was registered at a cel ...Более

Detection of Escherichia coli O157:H7 using immunomagnetic separation and mPCR in Turkish foods of animal origin

Zafer GÖNÜLALAN

The present study was conducted to investigate the presence of Escherichia coli O157:H7 in food samples of animal origin and to detect its virulence genes by immunomagnetic separation technique and multiplex PCR (mPCR). A total of 500 samples (consisting of diced meat, minced meat, burger, raw cow's milk and raw cow's milk cheese) were analysed. Escherichia coli O157:H7 was detected in 5 (1%) of 500 analysed samples including two diced meat, one minced meat and two raw-milk cheese. None of the burger samples tested contained E. coli O157:H7. Three isolates obtained from minced and diced meat w ...Более

Two new records of the Coniopteryx (Neuroptera: Coniopterygidae) species for the Turkish fauna

Savaş CANBULAT

Two species of the family Coniopterygidae, Coniopteryx (Xeroconiopteryx) loipetsederi H. Aspöck, 1963 and C. (Coniopteryx) borealis Tjeder, 1931, are here recorded for the first time in the Turkish fauna. Morphological and ecological notes as well as the distribution map with new recording sites are also provided. For C. loipetsederi, this is the most eastern record, and the eastern limits of the range of C. borealis have also been extended. - Keywords: Neuroptera, Coniopterygidae, Coniopteryx loipetsederi, Coniopteryx borealis, new records, Turkey

Formation of the plexus sacralis in pheasants (Phasianus colchicus mongolicus) and macroanatomic investigation of the nerves originating from the plexus sacralis

Fatih Ramazan İSTANBULLUGİL | Hüseyin KARADAĞ | Şamil SEFERGİL

The purpose of this study was to investigate the formation of the plexus sacralis in the Kyrgyz pheasant (Phasianus colchicus mongolicus) and the origin of the nerves emerging from the plexus sacralis. Five adult male Kyrgyz pheasants were used that had been hunted in their natural habitat near the town of Tokmok in the Chuy region of Kyrgyzstan. The plexus sacralis was found to be formed in the lumbar region by the ventral strands of sacral nerves 1 to 5, originating in the spinal cord. The plexus is composed of the truncus cranialis, which consists of the ventral strands of the first 3 nerve ...Более

Cytochemistry of peripheral blood leukocytes in thoroughbred foals

Emrah SUR

We attempted to characterize the cytochemical staining patterns of leukocytes and to determine the percentages of alpha-naphthyl acetate esterase (ANAE) and acid phosphatase (ACPase) positive lymphocytes in peripheral blood of thoroughbred foals at different ages. Blood samples were obtained from the jugular veins of 60 healthy thoroughbred foals, 1 day, 3 days and 1 year old. Each age group included 10 male and 10 female animals. Peroxidase (PO) activity was detected in neutrophils, eosinophils and monocytes. Lymphocytes were negative for PO staining. Periodic acid-Schiff (PAS) staining was o ...Более

Composite Bows from Uch-kurbu in Kyrgyzstan

Kubatbek TABALDİYEV

The article addresses the topic of composite bows from nomadic sites in Tien Shan and Zhetysu. Horn plates from bows discovered in 2008–2009 at Uch-Kurbu on the Tosor River, the Issyk-Kul Depression (Kyrgyzstan), are described and analyzed. The original design of the wooden core of the bow and the location of horn plates thereon are reconstructed. Based on our earlier classification of weapons, these are composite bows of the Xiongnu-Xianbei period. Two subtypes are identified, based on the design of plates at the ends of the bow. Evidently, composite bows with end, medio-lateral, and medio-fr ...Более

Sulfisoxazole (SO) was grafted to glassy carbon electrode (GCE) via the electrochemical oxidation of SO in acetonitrile solution containing 0.1 M tetrabutylammoniumtetra-fluoroborate (TBATFB). The prepared electrode was characterized by using cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), reflection–absorption infrared spectroscopy (RAIRS) and X-ray photoelectron spectroscopy (XPS). The ellipsometric thickness of SO nanofilm at the glassy carbon surface was obtained as 14.48 ± 0.11 nm. The stability of the SO modified GCE was studied. The SO modified GCE was also utiliz ...Более

Surface characterization of dinitrophenyl-diaminophenyl nanoplatform on glassy carbon

Ali Osman SOLAK

2,4-dinitrophenol (DNP) was covalently bonded to glassy carbon substrate by cyclic voltammetry (CV) technique. 2, 4-diaminophenol film (DAPO) was acquired with electrochemical reduction of 2,4-dinitrophenol film (DNPO). Prepared films were characterized by X-ray photoelectron spectroscopy (XPS) and germanium attenuated total reflection infrared (GATR-FT-IR) spectroscopy. A hemispherical germanium ATR element used with p-polarized light at 65° incidence angle yielded high signal/noise IR spectra for monolayer coverage of molecules on glassy carbon substrate. Layer thickness of films was measure ...Более
