19 yüzyıl Osmanlı-Türk edebiyatında öykü

Ankara : Türk Edebiyatı Bölümü, Bilkent Üniversitesi, 2008.Thesis (Master's) -- Bilkent University, 2008.Includes bibliographical references leaves 149-155.In this study, the works Letaif-i Rivayat by Ahmet Mithat (1844-1912), Müsameretname by Emin Nihat (?), Küçük Şeyler by Samipaşazade Sezai (1860- 1936), and Karabibik by Nabizâde Nazım (1862-1893), which all have a number of aspects in common and are considered by Ottoman-Turkish short story critics to be among the first examples of the genre, will be examined by means of close reading, by interpretation of the effects of extra-literary conditions, and in comparison with Eurocentric approaches to the short story. In the critical writings on the above short stories that were produced in the post-Tanzimat era, allegations of imitation similar to those directed at the novels of the same era were put forward. A short story standard defined by Western literatures has been introduced into Ottoman-Turkish literature as the ideal formula. As a result of this approach, when the works in question are found to contain any aspects that do not fit such criteria, they are harshly denounced for their lack of skill, of competence, and of sense. However, as will be demonstrated in the second chapter of the study, there is in fact little agreement about the criteria themselves, as they continue to be debated and criticized from a variety of perspectives even within the context of Western literature. Nonetheless, quite dramatically, such criteria have been established as an unshakable foundation in Turkish short story criticism. A number of problems, particularly the classification of the genre, arise within this Eurocentricoriented critical approach insofar as such an approach neglects these works’ local background and the unique circumstances under which they were produced. In addition to the above considerations, this study aims to point out certain basic deficiencies detectable in previous criticism, such as the insufficient emphasis on the difference between the short story as a genre and narration as a means of expression. The study will also attempt to emphasize, in regard to the writing of the literary history of the Ottoman-Turkish era, the importance of defining these preliminary examples of the genre as well as their interactions and changes, and thus aims to underline the significance of these works’ local background as against the Western criteria forced upon them in previous criticism. Bearing in mind all of the above considerations concerning the Eurocentric critical approach and its deficiencies, the last chapter of the study will focus on the short stories themselves, and the data collected from these works will be interpreted inductively in an attempt to emphasize the idea of the locality and originality of Ottoman-Turkish literature. Ultimately, it will be shown that, unlike the general suppositions made in previous criticism, the aim of the writers of these short stories was not mere imitation, and that even the alleged Western influences on these works were reshaped and transformed in accordance with the uniqueness of the texts. Consequently, the study aims to contradict previous approaches, which support the idea that the short story, as a genre, originated wholly in Western literature.Aydın, HilalM.S

Nanofiller-based novel hybrid composite membranes for high-capacity lithium-sulfur batteries

Herein, Al2O3 nanofiller-reinforced lithiated Nafion:Aquivion hybrid composite ion-exchange membranes have been produced by mixing lithiated Nafion and Aquivion ionomers. After the electrochemical tests, the Li-Naf : Li-Aqu/1 : 2 compound, which offers the best electrochemical performance, was selected. Lithiated hybrid composite membranes were obtained by reinforcing Al2O3 nanofillers at different rates to this composition. The ion exchange capacity, polysulfide transition and solvent uptake of the obtained membranes were investigated and the structural characterizations were applied by tensile test, Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), and membrane morphology was examined with Field Emission Scanning Electron Microscopy (FESEM). For performing the electrochemical tests, CR2032 half cells were designed. Electrochemical characterizations of the produced membranes were carried out by Cyclic Voltammetry (CV), Electrochemical Impedance Spectroscopy (EIS), and galvanostatic charge-discharge tests. The best electrochemical performance was achieved with 868 mAhg−1 discharge capacity and 63.8 % capacity retention when Li-Naf : Li-Aqu/1 : 2 composition was reinforced with 1 % Al2O3 nanofiller. As a result, lithiated hybrid composite ion exchange membranes could prevent the shuttle effect of polysulfides while enabling the passing of Li ions for high-performance Li−S batteries

Security Vulnerability Assessment of Google Home Connection with an Internet of Things Device

With virtual assistants, both changes and serious conveniences are provided in human life. For this reason, the use of virtual assistants is increasing. The virtual assistant software has started to be produced as separate devices as well as working on phones, tablets, and computer systems. Google Home is one of these devices. Google Home can work integrated with smart home systems and various Internet of Things devices. The security of these systems is an important issue. As a result of attackers taking over these systems, very serious problems may occur. It is very important to take the necessary actions to detect these problems and to take the necessary measures to prevent possible attacks. The purpose of this study is to test whether an attack that attackers can make to these systems via network time protocol will be successful or not. Accordingly, it has been tried to attack the wireless connection established between Google Home and an Internet of Things device over the network time protocol. Attack results have been shared.With virtual assistants, both changes and serious conveniences are provided in human life. For this reason, the use of virtual assistants is increasing.

Anesthetic Management of Patient for Case with Apert Syndrome

Apert syndrome is an autosomal dominant inherited mandibulofacial dysostosis characterized by craniosynostosis, syndactyly, high forehead, broad nose, maxillary hypoplasia, synostosis of cervical vertebrae, organ malformations, and mental retardation. It is rarely encountered and as there is little knowledge of the anesthesia practice for this syndrome in the literature, we present our anesthesia experience of a case undergoing bilateral syndactyly surgery

Reduced graphene oxide supported tin oxide-boron oxide flexible paper anodes for Li-ion batteries

Freestanding tin oxide-boron oxide/reduced graphene oxide (SnO2-B2O3/rGO) nanocomposite anode was produced for Li-ion cells. This binder-free flexible paper anode structure was fabricated by combining SnO2-B2O3 composite and graphene oxide which were synthesized through the sol-gel method and Hummers' method, respectively. Field emission gun scanning electron microscopy, high-resolution transmission electron microscopy, energy dispersive X-ray spectrometer, Fourier transform infrared spectroscopy, Raman spectroscopy, and X-ray diffraction were utilized to characterize anode materials. The Williamson-Hall (W-H) analysis was applied using XRD data to determine crystal size and strain of the lattice. Electrochemical tests, cyclic voltammetry, and electrochemical impedance spectroscopy measurements were performed to determine electrochemical properties of the anodes. The results indicated that the anode formed with SnO2-B2O3 particles anchored on the rGO layers provided higher discharge capacity (838 mAh g(-1)) than that of SnO2/rGO (395 mAh g(-1)) after 100 cycles. The electron-deficient nature of boron supplied an effective increase in electrochemical energy storage performance

Difficult Mask Ventilation in Obese Patients: New Predictive Tests?

Aim:The aim of our study was to evaluate specific factors in predicting difficult mask ventilation (DMV) in obese patients undergoing elective surgery.Methods:This prospective and observational study was performed in 90 obese patients. We assessed age, height, weight, sex, body mass index (BMI), dental structure, presence of facial hair, modified Mallampati test result, mouth opening, thyromental distance (TMD), sternomental distance, mandibular protrusion, mandibular length, neck circumference (NC), neck length, upper lip bite test result, height to TMD ratio, NC to TMD ratio (NC/TMD), and history of snoring and Obstructive Sleep Apnea syndrome for estimation of DMV.Results:The mean age of the patients was 40.9±9.4 years and the mean BMI was 44.7±6.2 kg/m2. Of all patients 38.9% were determined to have DMV. Clinical variables associated with DMV were male gender, mandibular length, snoring, NC, and NC/TMD. Multiple logistic regression analysis showed that male gender (p=0.047) and snoring (p=0.02) were independent factors.Conclusion:We believe that NC/TMD and ML are predictive tests for DMV in obese patients. Tests and measurements at the bedside are not sufficient alone and we believe that they will be more reliable when considered together

Modeling the combined effect of RNA-binding proteins and microRNAs in post-transcriptional regulation

Recent studies show that RNA-binding proteins (RBPs) and microRNAs (miRNAs) function in coordination with each other to control post-transcriptional regulation (PTR). Despite this, the majority of research to date has focused on the regulatory effect of individual RBPs or miRNAs. Here, we mapped both RBP and miRNA binding sites on human 3′UTRs and utilized this collection to better understand PTR. We show that the transcripts that lack competition for HuR binding are destabilized more after HuR depletion. We also confirm this finding for PUM1(2) by measuring genome-wide expression changes following the knockdown of PUM1(2) in HEK293 cells. Next, to find potential cooperative interactions, we identified the pairs of factors whose sites co-localize more often than expected by random chance. Upon examining these results for PUM1(2), we found that transcripts where the sites of PUM1(2) and its interacting miRNA form a stem-loop are more stabilized upon PUM1(2) depletion. Finally, using dinucleotide frequency and counts of regulatory sites as features in a regression model, we achieved an AU-ROC of 0.86 in predicting mRNA half-life in BEAS-2B cells. Altogether, our results suggest that future studies of PTR must consider the combined effects of RBPs and miRNAs, as well as their interactions.No sponso

A Heterosis Study for Some Agronomic Traits in Oat

The benefits of increased hybrid vigor, which often occur crossing unrelated plants or animals, have been recognized for centuries. In this study, hexaploid oat genotypes E44, K1, and A52 belong to A. sativa and A45 belonging to A. byzantina species were crossed. Heterosis, heterobeltiosis and standard heterosis values were calculated for 11 traits on 12 hybrids belong to K1 x E44 cross (ten hybrids), K1 x A45 cross (one hybrid) and K1 x A52 cross (one hybrid) with the parents. According to the results, parents varied for all traits while hybrids were varied for flag leaf length (FLL), tiller number (TN), 1000-grain weight (1000-GW), grain number per panicle (GNP), grain weight per panicle (GWP), single plant grain yield (SPGY) and biomass (B). K1 x A52 cross had the highest plant height (PH, 201.0 cm), TN (22) and 1000-GW (47.1 g). On the other hand, the highest stem diameter (SD, 9.0 mm), flag leaf width (FLW, 4.0 cm), panicle length (PL, 53.0 cm), GNP(98.0) and GWP (3.2 g) were obtained from K1 x A45 cross. However, K1 x E44 cross had the highest FLL (42.7 cm), SPGY (42.6 g) and B (108.7 g) values. Heterosis values of the oat crosses were significant for all traits except stem diameter, flag leaf length and panicle length, while stem diameter and panicle length for heterobeltiosis and plant height and stem diameter for standard heterosis. Heterosis values were ranked between -26.8 and 282.3% while heterobeltiosis values were between -45.6 and 248.0%, and standard heterosis values were between -2.7 and 419.0%. The highest heterosis and standard heterosis values (282.3 and 419.0%, respectively) were determined for SPGY in K1 x E44 population, while the highest heterobeltiosis value (248.0%) was determined for biomass in K1 x A52 population
