In this context, determination of painting techniques and materials employed and deterioration problems of the wall paintings, as of being part of built cultural heritage, have been crucial in terms of conservation. In this study, wall paintings existing in the Byzantine church-monastery edifice which have been uncovered in Kadıkalesi (Anaia) archaeological site were investigated for the purpose of identification of the original materials and painting technique. Mineralogical, chemical and micro-structural characteristic of the pigments and binding mediums employed in the fabrication of paintings; and basic physical properties, raw material compositions, mineralogical, chemical and micro-structural features of surface renderings underlying the painting layers were established. In the analyses, X-Ray diffraction (XRD), scanning electron microscope (SEM) equipped with energy dispersive X-ray spectroscopy (EDS), optical microscope, Fourier transform infra-red (FT-IR) spectroscopy and thermo-gravimetric analyzer (TGA) were used. On the basis of analyses results, it was determined that lime-secco technique was used in the fabrication of the investigated wall painting fragments; pigments were applied after mixed with lime (generally dolomitic lime) as binder on the surface of dry fine plaster. The density and porosity values of the fine plasters which paintings were executed are 1.20 g/cm3 and 40 % by volume respectively. The fine plasters were constructed with pure lime with small amount of soil material. Iron oxide-based pigments in red, yellow and purple paintings and aluminosilicate-based pigments; such as celadonite, glauconite in green paintings, lazurite and glaucophane in blue and dark blue paintings were employed

Assessment of quality of life and activities of daily living in Turkish patients with heart failure

Heart failure is an entire clinical syndrome affecting many aspects of life, rather than merely a usual disease. This cross-sectional study was designed to assess heart failure patients’ quality of life and activities of daily living (ADL). Seventy-five patients who applied to the cardiology department were included in the study. The data were obtained using the left ventricular dysfunction scale (LVD-36) and ADL scale. A statistically significant relationship was found between LVD-36 and ADL scores and New York Heart Association (NYHA) functional class, previous hospitalization, daily medication, age and education (P < 0.05). It was found that LVD-36 and ADL scores increase as the level of education increases and as the NYHA functional class, previous hospitalization, number of drugs taken daily and age decrease. The study found a statistically significantly negative relationship between quality of life and ADL (P < 0.05). In patients with heart failure, age, NYHA functional class, number of drugs taken daily independently affected the ADL scores. Additionally, in these patients, education, NYHA functional class, number of drugs taken daily and previous hospitalizations independently affected the quality of life. As the functional situation deteriorates and becomes severe, individual care, training, social support and consultation services for the patient and their family should be increased

Execution technique and pigment characteristics of Byzantine wall paintings of Anaia Church in Western Anatolia

In this study, material characteristics of wall paintings executed in 11th Century Byzantine Church located in archaeological site of Anaia (Turkey) were investigated to provide historical information of the painting techniques. For this purpose, physical, chemical and mineralogical compositions of the paintings were determined by X-Ray Diffraction, Fourier Transform Infrared spectroscopy, Scanning Electron Microscopy coupled with Energy Dispersive spectroscopy and Thermo-Gravimetric Analysis. Analysis results indicated that the paintings were executed using lime-secco technique. In this technique, pigments were mixed with lime and applied on a smooth plaster layer. Pigments used were mainly iron oxides for red, yellow and purple paintings, aluminosilicates such as celadonite for green paintings and lazurite for dark blue paintings

Quality Of Sleep And Factors Affecting Sleep Quality İn Hospitalized Patients In The Orthopedics And Traumatology Clinic

Purpose: In this study, our purpose was to determine the sleep quality and the factors affecting sleep quality of the hospitalized patients orthopedics and traumatology clinic. Methods: This study was conducted as a descriptive study in a hospital between March 30 and June 16, 2022. The sample of the study consisted of 200 patients hospitalized in the orthopedics and traumatology clinic. The data of the study were collected through face-to-face interviews with the patients using the ‘’Sociodemographic and Descriptive Characteristics Questionnaire’’ and the ‘’Richard-Campbell Sleep Questionnaire’’. Results: The average Richard-Campbell Sleep Questionnaire scores of the patients were determined to be 43.33&#177;28.31. While there was no statistically significant difference (p&gt;0.05) observed between the gender, preoperative or postoperative status, presence of noise, room lighting, room crowding, attached the body medical devices, treatment interventions during sleep hours, and Richard-Campbell Sleep Questionnaire score averages of the patients; a statistically significant difference was found in the Richard-Campbell Sleep Questionnaire score averages based on pain and medical diagnosis (p&lt;0.05). It was found that the variation in Richard-Campbell Sleep Questionnaire scores attributed to patient’s pain and diagnosis variables is 8 (R20.082). An increase of one unit in the presence of pain led to a decrease of 8.571 unit in sleep quality and the sleep quality of patients diagnosed with coxartrosis decreased by 12.298 units. Conclusions: The patients&apos; sleep quality was found to be below the moderate level, and it was observed that sleep quality was significantly affected by pain and diagnosis.Acıbadem Üniversitesi Sağlık Bilimleri Dergis

A comparative real-time speed control of PMSM with Fuzzy Logic and ANN based vector controller

This paper presents, analyzed real-time speed control of Permanent Magnet Synchronous Motor (PMSM) under constant load by using Fuzzy Logic (FL) controller and recurrent Artificial Neural Network (ANN) controller. A closed loop PMSM drive system is improved using the mathematical model of the PMSM in Matlab / Simulink. Two types of controllers are used; the first controller is the real-time FL controller and the second controller is a real-time recurrent ANN controller in terms of smoother speed response. Whole drive systems is simulated in Matlab/Simulink program. The simulation results show that the focused ANN controller produce considerable control performance compare to the FL controller on controlling speed reference variation

İÇSEL BÜYÜMEDE İÇSELLEŞME SÜREÇLERİ: TÜRKİYE ÖRNEĞİ

Bu çalışmanın amacı, içsel büyümenin temel girdilerinden bilgi, beşeri sermaye ve teknolojik gelişmenin, eğitim, Ar-Ge, üniversite-sanayi işbirliği, yaparak öğrenme ve yayılma yoluyla, üretim süreçlerinde nasıl içselleştiklerini ortaya koymaktır. Eğitim ile bilgi birikimleri artan kişiler iş hayatında görev aldıkça, Ar-Ge ile elde edilen yeni teknolojiler üretimde kullanıldıkça, üniversite-sanayi işbirliği ile teorik bilgi stoku uygulamayla buluştukça, yaparak öğrenme ile çalışanların deneyimleri arttıkça firmaların ve ülkelerin rekabet güçleri artabilecektir. Türkiye için 1970-2001 dönemi verileri kullanılarak yapılan ampirik analizde, emek ve sermaye faktörleri ile GSMH arasında pozitif; eğitim harcamaları ve dış ticaret hacmi ile sermaye stoku arasında ise negatif bir ilişki bulunmuştur
