Reliable Detection of Broken Bar Fault through Negative Sequence of Stray Flux in Induction Motors
No full text2023 IEEE International Electric Machines and Drives Conference, IEMDC 2023 -- 15 May 2023 through 18 May 2023 -- 192453As well-known, the broken bar fault affects the harmonic content of the stator current and airgap & stray flux. This paper proposes to detect broken bar fault through negative sequence stray flux spectrum in induction motors (IMs). For this purpose, three stray flux data which have 120o relative phase differences are collected from the vicinity of IMs. Then, stray flux space vector is calculated and analyzed at low frequency range when the motor is operated as both healthy and broken bar cases. It is shown that there are some effective signals such as -((fs-fr)±2sfs) to detect broken bar fault in negative sequence stray flux spectrum while only sidebands of fundamental signatures rise up in positive sequence stray flux spectrum. Comparative 2D finite-element simulations results including current space vector prove that the negative sequence stray flux spectrum can yields more effective results than classical stator current and stray flux analysis in induction motors. © 2023 IEEE
Kronik bel ağrısında ağrı inançlarının cinsiyetlere göre semptom şiddeti ile ilişkisi
No full textAmaç: Kronik bel ağrılı bireylerin ağrı inançlarının cinsiyetlere göre semptom şiddetleri ile ilişkisini incelemek. Yöntem: Çalışmaya 18-65 yaş aralığında 204 kişi katıldı. Katılımcıların cinsiyete göre yaş ortalamaları sırasıyla erkeklerde 42.21±14.24, kadınlarda 41.65±13.41 idi. Çalışmada ağrı inançlarını ölçmek için Ağrı İnançları Ölçeği (AİÖ) ve ağrı şiddetlerini ölçmek için de Numerik Derecelendirme Sakalası (NRS-11) kullanıldı. Bulgular: Kronik bel ağrılı bireylerin ağrı inançlarının semptom şiddeti ile ilişkisinin cinsiyetlere göre anlamlı farklılığa sahip olduğu bulundu (p=0.001). AİÖ ve NRS-11 değerleri cinsiyetler arası istatistiksel olarak anlamlı farklılığa sahip olup (p=0.001), kadınlarda daha yüksek düzeyde bulundu (p<0.001). Sonuçlar: Araştırmamızda ağrı inançlarının ve kronik ağrıyı algılamanın cinsiyete göre değiştiğini tespit ettik. Cinsiyet faktörünün, yaşanılan ağrı şiddeti ve ağrılara dair geliştirilen inançların gücüyle ilişkili olduğu görüldü. Kadın bireylerin erkek bireylere göre daha yüksek ağrı şiddeti skor ortalamasına sahip olduğu, organik ve psikolojik ağrı inançlarının da daha fazla olduğu bulundu

A semi-structured interview form was used as a data collection tool in the research. The data obtained in the research were analyzed by content analysis. As a result of the research, it was determined that all Social Studies teachers were of the opinion that there was a relationship between Social Studies teaching and the History discipline. History discipline is used effectively in Social Studies teaching. Social Studies teaching and History discipline are parts of an inseparable whole. By teaching history to students, in addition to historical knowledge; It may be easier and healthier to gain concepts such as national consciousness and common values. The discipline of history is useful in teaching Social Studies in terms of creating a link between the past and the future. Social Studies teachers have a common opinion that it is possible to provide students with the values, basic skills and achievements in the Social Studies curriculum through the discipline of History
İdiyopatik Ani Sensörinöral İşitme Kayıplı Hastalarda Uzun Dönemde Tinnitus ve Vertigo Semptomlarının Yaşam Kalitesine Etkisi
No full textObjective: To determine the effect of tinnitus and vertigo symptoms on quality of life in the long term after medical treatment in individuals with idiopathic sudden sensorineural hearing loss. Material and Methods: The study included 18-65 years old 63 patients (20 women-43 men) who were diagnosed with idiopathic sudden hearing loss at Ear Nose and Throat Diseases Polyclinic of İnönü University Turgut Özal Medical Center and had at least 20 dB HL improvement in the mean pure tone threshold as a result of the medical treatment. A Demographic Data Form, the Dizziness Handicap Inventory, the Tinnitus Handicap Inventory, and the Multidimensional Index of Life Quality were administered to all participants. The patients were assigned into two groups as those with dizziness and tinnitus symptoms (n=33) and those without symptoms (n=30). Results: No statistically significant difference was found between the symptomatic and nonsymptomatic groups according to age, time from diagnosis and gender (p>0.05). The groups show a homogeneous distribution according to age, time since diagnosis and gender. Index of Life Quality Scale physical health scores, mental health scores, interpersonal relations scores, and total score were significantly higher in the non-symptomatic group than in the symptomatic group (p0.05). Conclusion: Although there was an improvement in hearing thresholds after treatment in individuals with idiopathic sudden sensorineural hearing loss, tinnitus and vertigo symptoms could persist in the long term and these symptoms had a serious negative impact on the individual's quality of life. These individuals should be followed up after treatment and holistic evaluations should be made with audiovestibular tests. The quality of life of individuals can be increased by applying appropriate treatment/rehabilitation with a multidisciplinary approach. © 2022 Turkey Association of Society of Ear Nose Throat and Head Neck Surgery.

Effect of Altitude and Location on Compositions and Antioxidant Activity of Laurel Cherry (Prunus Laurocerasus L.)
No full textThe compositional and antioxidant properties of cherry laurel (Prunus laurocerasus L.) fruit, which grow in two different locations (Trabzon and Rize) and altitudes, were investigated. The results indicated that antioxidant activity, total phenolic content, citric acid, sugars and phenolic compounds were affected by location and altitude. While fruits of Trabzon province have higher composition content than those of Rize province, fruits collected at low altitudes in both regions were found to have superior properties. Total phenolic content in fruits from Trabzon and Rize provinces increased from 21.90 to 23.32 and from 16.84 to 18.91 mg gallic acid equivalent / 100 g dry weight (DW), ?-carotene increased from 5.19 to 6.75 and from 4.16 to 5.61 mg / kg DW, and total sugar increased from 81.68 to 131.99 and from 86.44 to 99.58 mg / g DW when altitude decrease from 351 to 49 m and 316 to 14 m, respectively. Chlorogenic acid (1404.46-7358.63 mg / kg DW) and rutin hydrate (1491.05-2712.91 mg / kg DW) were major phenolic compounds in all samples
The Relationship Between Anxiety and Hopelessness Levels Among Nursing Students During the COVID-19 Pandemic and Related Factors
No full textOutbreaks caused by environmental effects such as COVID-19, MERS, SARS, or Ebola cause problems such as fear, anxiety, loneliness, depression, and hopelessness for people with or without a high risk of illness. This study aims to determine the levels of hopelessness and anxiety experienced by nursing students during the COVID-19 outbreak. This descriptive and cross-sectional study was conducted with students of a state university. In the collection of the data, Descriptive Characteristics Form prepared by the researchers, the Generalized Anxiety Disorder Test (GAD-7), and the Beck Hopelessness Scale (BHS) were used. The mean GAD-7 score of the students participating in the study was 6.65 +/- 5.03 and the mean BHS score was 6.11 +/- 4.91. It was determined that the score of GAD-7 and BHS were a significant positive high relationship between them (p < 0.001). Anxiety and hopelessness levels were found to be statistically significantly higher for those whose sleep and eating patterns affected negatively due to the pandemic, those who feared the pandemic and its economic effects, and those who did not want to work in the hospital during the pandemic period. There was a relationship between anxiety and hopelessness levels of nursing students participating in the study
SABRİ ÜLGENER’İN FİKİRLERİ ÜZERİNDEN SAATLERİ AYARLAMA ENSTİTÜSÜ ADLI ROMANIN DEĞERLENDİRİLMESİ
No full textKalkınma, 21. yüzyılda hala az gelişmiş veya gelişmekte olan toplumların gündemindedir. Bir ekonomik sistemin, kalkınma aşamalarını etkin bir şekilde katedebilmesi için en başta Sabri Ülgener’in tabiriyle “iktisadi zihniyetinde” bu dönüşümü gerçekleştirmiş olması gerekir. Değişen zihinler, davranışların değişmesine ve iktisadi tabirle “çıktı”ların değişmesine vesile olur. Bu sebeple “iktisadi zihniyeti” doğru anlamak ve hatta ayrıntılarına vakıf olmak önemlidir. Toplumun içerisinden çıkan edebi eserler, toplumsal düzen üzerinde etkili olan birçok unsuru yansıtmaktadır. Bu unsurlardan biri de iktisattır. Bu da edebi eserlerin ortaya konduğu dönemlerin ekonomik durumundan bağımsız olmamalarından kaynaklanmaktadır. Özellikle romanlarda, eserin konusunun betimlenmesinde o günkü şartlar da anlatılmakta, olay örgüsü içerisinde kahramanların yaşadıkları ister istemez dönemin iktisadi zihniyetini yansıtır durumda olmaktadır. Bu bağlamda ve bu çalışma özelinde Tanpınar’ın Saatleri Ayarlama Enstitüsü adlı romanı Türk toplumunun iktisadi zihniyetini anlamak adına incelenmiştir. Yapılan değerlendirmelerde Ülgener’in fikirleriyle karşılaştırma yapılmıştı
