Reconfigurable Voltage-Mode First-Order Multifunction Filter Employing Second-Generation Voltage Conveyor (VCII) With Complete Standard Functions and Electronically Controllable Modification
No full textIn this contribution, the realization of a first-order, two-input, single-output voltage-mode multifunction filter employing a second-generation voltage conveyor (VCII) is described. The proposed first-order versatile filter is extremely simple, composed of a single VCII and three passive devices. Because of its low output impedance, the output voltage node can be easily cascaded with other voltage-mode configurations without the requirement of any buffers. In the same circuit topology, the proposed firstorder filter provides various filtering functions: inverting and non-inverting low-pass (LPF), inverting and non-inverting high-pass (HPF), as well as inverting and non-inverting all-pass (APF). The digital method allows the selection of output first-order filtering functions without the need for additional circuits such as inverting or double-gain amplifiers. Furthermore, the pass-band gain of the low-pass and high-pass responses can be adjusted by varying the resistance or capacitance values without influencing the pole frequency as well as the phase response. The influence of VCII's current/voltage gain errors and parasitic elements on filtering performance is also investigated. Moreover, the modification of the proposed lagging phase allpass filter to achieve electronic controllability is also proposed by replacing the passive resistor with the operational transconductance amplifier (OTA). The 0.18 mu mTSMCCMOSstructure of the VCII employed in the proposed filter operates in the subthreshold region and utilizes the bulk-driven technique (BD), enabling it to operate with 0.4V supply voltage and consuming 383 nW of power. The total harmonic distortion (THD) of the LPF with an applied input voltage V-inpp =300mV @ 50Hz is -49.5 dB. An application example as a quadrature sinusoidal oscillator realized from the proposed first-order allpass filter and lossless integrator is also included. The performance of the proposed reconfigurable voltage-mode first-order filter is simulated and experimentally tested using a commercially available AD844 IC-based VCII with +/- 5 V power supply.University of Defence within the Organization Development Project VAROPSThis work was supported in part by the University of Defence within the Organization Development Project VAROP
Underwater acoustic performance of SiC foam ceramic materials
No full textOne of the major tasks of the underwater warfare is to detect underwater objects such as vehicles, vessels, weapons and equipment. The conduct of underwater warfare mostly depends upon the advancement of detection and identification sensors and materials. The wide variation in types and characteristics of materials may affect the underwater detection capabilities despite recently developed sonar systems. The materials with high porosity are known to provide lower acoustical signature than conventional metallic plates in common. The aim of this study is to examine the acoustical signature and the efficiency of open celled SiC foam ceramics as covering and/or casing material for naval mines. Sonar frequencies widely used in mine countermeasure operations for detection purposes, 80 kHz, 85 kHz, 90khZ, 95 kHz and 100 kHz were applied to the acoustic tests. The experimental results obtained from the study shows that the SiC foam ceramic plate leads a 19,2% reduction in reflection, 90,5% and 96% lower values are obtained in transmission and 78,4% and 68,6% lower values are obtained at 60 degrees and 30 degrees in scattering compared to the reference steel plate

The aim of the study is to examine the mediating role of defense mechanisms in the impact of childhood traumas on the reality testing and object relations of women who are victims of violence by their spouse or partner, based on the object relations theory. The research was carried out according to the relational survey model, one of the quantitative research methods. The sample group consists of women residing in various districts of Istanbul because they have been exposed to any type of violence by their partner or spouse. A sample size of 395 people was reached. Personal Information Form, Childhood Trauma Questionnaire, Defense Style Questionnaire-40, Bell Object Relations and Reality Testing Inventory were used in the study. In order to test the effect of mediating variables on the model, the two-stage approach of structural equation modeling was used. In order to improve the model-data fit in one-dimensional scales, the parcelling technique was applied to the scale items. Parceling was done by calculating the corrected item-total correlation values. According to the relationship between the variables examined with the help of the structural equation model, it was found that mature and immature defense mechanisms fully mediated the effect of childhood traumas on the quality of object relations and the level of reality testing. According to the structural equation modeling, which allows to reveal the causal relationships between the variables and to examine the tested model with various fit indices, the mediating effect of neurotic defense mechanisms, childhood traumas, object relations and reality assessment level could not be determined. Other than that, our hypotheses have been confirmed and our findings are consistent with literature research and theoretical knowledge
THE EFFECTS OF SOCIAL MEDIA ON CONSUMER BEHAVIOR: THE CROSS-NATIONAL COMPARISON
No full textAs early as twenty years ago, social media (SM) entered and integrated into people’s lives by becoming an essential part that can’t be separated, hence having a great impact on them, especially on consumers. Also, marketers strategically utilize SM to reach audiences and potential consumers since SM became one of the best mediums for attracting consumers by suppressing all traditional communication methods. Different SM applications started to spread gradually in different societies and culturally specific SM tools were developed rapidly. SM use has been an important part of daily life in every culture, except in closed societies. This study aims to reveal the effect SM has on consumers and their online behavior from a cross-cultural perspective. In the study, it is assumed that electronic word of mouth (E-WOM) and SM advertisements are affected by independent factors. Consumers' online decision-making styles are included in the research as another question that needs to be answered. It is assumed that the cultural factors that affect online consumer behavior and consumers' decision-making styles will differ between cultures. This study uses data from a survey of 300 Turkish consumers in Turkey and 250 Russian consumers in Russia. According to the data, 55.7% of the Turkish and 56.4% of Russian participants reported having purchased some products after a month of being exposed to adverts
Comparison of the efficacy of the mouse hepatic and renal antioxidant systems against inflammation-induced oxidative stress
No full textThis study was conducted to compare the efficacy of the mouse hepatic and renal antioxidant systems against inflammation-induced oxidative stress. Increased Il-1 and Il-6 expressions, markers of inflammation, were represented by inflammation models in mouse liver and kidney tissues injected intraperitoneally with LPS. After establishing the model, the GSH level and the GSH/GSSG ratio, which are oxidative stress markers, were investigated in both tissues treated with LPS and the control group. The expression of Trx1, TrxR, and Txnip genes increased in the liver tissues of LPS-treated mice. In the kidney tissue, while Trx1 expression decreased, no change was observed in TrxR1 expression, and Txnip expression increased. In the kidneys, TRXR1 and GR activities decreased, whereas GPx activity increased. In both tissues, the TRXR1 protein expression decreased significantly, while TXNIP expression increased. In conclusion, different behaviors of antioxidant system members were observed during acute inflammation in both tissues. Additionally, it can be said that the kidney tissue is more sensitive and takes earlier measures than the liver tissue against cellular damage caused by inflammation and inflammation-induced oxidative stress.Scientific and Technological Research Council of Turkiye (TUBITAK) [114Z277]; Scientific Research Projects Coordination Commission of Atatuerk University [PRJ2016/151]; Council of Higher Education (CoHE) Scientific and Technological Research of Tuerkiye (TUEBITAK) [2211]This work was financed by the Scientific and Technological Research Council of Turkiye (TUBITAK) (Project No.114Z277) and the Scientific Research Projects Coordination Commission of Atatuerk University (Project no.

BANKA KREDİ HACMİ İLE EKONOMİK BÜYÜME ARASINDAKİ İLİŞKİ: DOĞRUSAL OLMAYAN EŞTÜMLEŞME ANALİZİ
No full textEkonomik büyüme ve finansal gelişme arasındaki ilişkinin ele alındığı araştırmaların önemli bir kısmında banka kredilerinde yaşanan genişleme sonucu ekonomik büyüme gerçekleştiği görülmektedir. Ancak aynı zamanda ekonomik büyümenin banka kredi hacmi üzerindeki etkisinin tespit edildiği çalışmalar da mevcuttur. Dolayısıyla henüz ilişki yapısının belirlenmesinde ortak bir fikir birliği olmadığını söylemek mümkündür. Buradan hareketle banka kredi hacminin ekonomik büyümeyi olumlu yönde etkilemesini amaçlayan para politikalarının etkinliği tartışmalı hale gelmektedir. Bu çalışmada amaç; Türkiye’nin ekonomik büyümesi için sabit sermaye toplamı, mevduat bankalarına ait toplam kredi hacmi, kamu mevduat bankaları kredi hacmi ve özel mevduat bankaları kredi hacmi arasındaki doğrusal olmayan eştümleşme ilişkisinin araştırılmasıdır. KSS (2006) eştümleşme testinde değişkenler arasında uzun dönemli bir eştümleşme ilişkisinin farklılaştığı tespit edilmiştir. Eştümleşmenin varlığından hareketle oluşturulan ESTAR hata düzeltme modeli mekanizmasının Türkiye’de GSYİH ve mevduat bankalarına ait toplam kredi hacmi modelinde çalıştığı sonucuna ulaşılarak ilgili literatüre öneriler getirilmiştir
The prevalence and impact of primary headaches in orphaned children: a cross-sectional, observational study in a boarding school
No full textThe relationship between headache and stressful life events experienced in childhood has been found mostly associated with recurrent primary headaches and headache chronicity. We aimed to investigate the prevalence, clinical characteristics, daily life impact of migraine and tension-type headache in orphaned children with low income in a boarding school. Four hundred and fifteen permanent boarders aged 12-17 years were evaluated using the Structured Headache Questionnaire, the Pediatric Migraine Disability Assessment Scale (PedMIDAS), the Strength and Difficulties Questionnaire and Visual Analogue Scale (VAS). Prevalence of primary headache was 59.8%; 24.1% for migraine; 35.7% for tension-type headache; 4.1% for chronic migraine; and 2.4% for chronic tension-type headache. Prevalence of probable diagnoses was found to be higher in early ages; however, definite diagnoses became more common with age. Sex distribution was affected by age in migraineurs. The most distinctive features separating migraine were high frequency, pain severity, throbbing/pounding nature, photophobia, phonophobia, nausea, vomiting, and aggravated by physical activity. Prodromal symptoms and triggering factors were more closely associated with migraine. Sleep was the most common method to relieve of headache, taking medicines was preferred more commonly in migraineurs with a higher mean number of analgesics. Mean VAS, PedMIDAS, and total difficulty scores were higher in migraineurs, emotional problems were found increased in migraine. Headache is underestimated in pediatric population when probable diagnoses are not evaluated. The prevalence of primary headaches and the risk of chronic headaches are high in orphaned students, especially in older adolescent girls, and the effect of headache on daily life is evident

The novel Mutercim as a site of transfiction: A case of translation in life and the translation of life in the transformational republican era in Turkey
No full textTranslation has a rich history in Ottoman and Turkish literature, and a study of transmesis in a transfiction has great potentials for analyzing the praxis and pragmatics of translation in Turkey. This study focuses on the translational action in the mirror of fiction with a case study on the Turkish novel Mutercim (2013) [Translator] by Alper Gurkan. Investigating translation both as a performance (i.e., text) and an experience (i.e., agency), the analysis is constructed upon four categories: 1) actual translation in its technical sense; (2) the agency of the translator as a subject and object of the translation; (3) figurative/metaphoric use of translation; and (4) the potentials of mistranslation vis-a-vis pseudotranslation. The multi-layered translational baggage of the novel serves as a site par excellence to delimit the definition of translation, which begins as a faithful translation and ends up as an almost genuine writing, a mistranslation in the novel. Skillfully imposed attributions to change, transformation, fragmentation, and dislocation under a translational context determine the fate of both the text and the agent in Mutercim: corrupted and originally lost. This elegy for origins resonates in the discourse of the author as neo-Ottoman fantasy where we witness the emergence of translation as the lieu of historical criticism under the guise of a transfiction
