GELENEKSEL YOLLARLA ÜRETİLMİŞ TURŞU ÖRNEKLERİNDEN LAKTİK ASİT BAKTERİLERİNİN İZOLASYONU, MOLEKÜLER YÖNTEMLER KULLANILARAK TANIMLANMASI VE BAZI FONKSİYONEL ÖZELLİKLERİNİN BELİRLENMESİ
No full textBu çalışmada ülkemizin farklı illerinden toplanmış 17 adet geleneksel turşu örneğinden Laktik Asit Bakterileri (LAB) izole edilip tanımlanmış ve izolatların fonksiyonel nitelikleri karakterize edilmiştir. Genotipik ayrıştırma sonucunda 9 farklı türe ait 21 suş tespit edilmiştir. Takiben bu 21 suşun potansiyel probiyotik değerlendirmeleri safra tuzlarına direnç ve düşük pH’da gelişim açısından test edilmiş ve Lactiplantibacillus plantarum ve Levilactobacillus brevis suşlarının yüksek canlılık gösterdiği tespit edilmiştir. İzolatlarının antibiyotik dirençlerinin ise oldukça düşük seviyede olduğu gözlenmiştir. Önemli olarak antifungal aktivite açısından suş spesifik etki gözlenirken, antibakteriyel aktivite noktasında oldukça güçlü aktivite sergilemişlerdir. Son olarak turşu izolatlarının GABA üretim potansiyelleri açığa çıkarılmış ve Levilactobacillus brevis VB13 suşunun 0.628±0.11 mg/mL GABA üretebildiği gösterilmiştir. Elde ettiğimiz sonuçlar turşuda bulunan LAB çeşitliliğini ve bu suşların fonksiyonel etki potansiyelini göstermesi bakımından önem arz etmektedir
The willingness of elderly care program students to care for older adults and the associated factors: a multi-centered research
No full textProspective technicians for elderly care are indispensable elements that should be included in the relevant system to meet the ever-increasing care needs of the aging world population and increase the quality of care. This research was conducted to evaluate the attitudes of students in the elderly care program at the associate degree toward the older adults and their willingness to provide care. The sample of this descriptive and cross-sectional study comprised 525 volunteer students in elderly care programs in five vocational schools of higher education located in northeastern Turkey between June 2020 and September 2020. Mean, standard deviation, number, percentage, independent t-test, and correlation analysis were used to evaluate the data. The study showed that the mean age of the students involved in the study was 20.3 +/- 1.6. 77.7% of them were female, and 61.9% were in the first grade. Students' willingness to care for older adults was found to be at a moderate level (36.3 +/- 6.0). The students had a negative attitude (137.4 +/- 26.7) about aging and elderliness. The willingness of male students to care for older adults was significantly higher (p < .05). Those who did not live with an older adult in the same house before had a more negative attitude toward them (p < .05). To get rid of personal and social stereotypes and have a positive attitude toward older adults, students should be provided to work in clinical environments that will allow them to spend more time with them
The Hurşid-Name masnavi of Şeyhoglu Mustafa in terms of narrative
No full textLisansüstü Eğitim Enstitüsü, Türk Dili ve Edebiyatı Ana Bilim Dalı, Eski Türk Edebiyatı Bilim Dalıİnsanlık tarihi kadar eski olan anlatı her zaman kendini herhangi bir türde ifade imkanı bulmuştur. Bu türler çağlara göre değişse de ismi bazen masal bazen destan bazen mesnevi bazen roman olsa da hepsinin ortak noktası olayların öykülenmesidir. Metinler, ifade tarzları, biçimleri birbirinden farklı olsa da anlatmaya bağlı metinlerin hepsinin temeli bir olaya dayanır. Ele alınan olay masalda olağanüstülüklerle, destanda kahramanlıklarla süslenirken mesnevide şiirle süslenmiştir. Divan edebiyatında ustalık gerektiren mesneviler, divan şairlerinin hünerlerini göstermek için başvurdukları bir nazım biçimidir. Mesneviler şiir şeklinde yazılan fakat içerisinde olay örgüsü, kahramanlar, yer, zaman, bakış açısı gibi yapı unsurlarını hatta anlatım teniklerini barındıran metin türüdür.Tez çalışmamızda, mesnevilerin kısmen de olsa gözardı edilen yapı unsurlarını ve anlatım tekniklerini hikâye, roman gibi türlere yakınlaştırma iddiasında bulunmadan klasik metne uygun olacak şekilde ortaya konmaya çalışılmıştır. Mesnevide yer alan olaylar olğanüstülükten uzak, yaşanabilir olduğu için mekân isimlerinin gerçekliği, kullanılan dilin o dönemin günlük konuşma diline yakınlığı gibi unsurlar gözönünde bulundurulduğunda anlatmaya bağlı metinlerle benzerlik gösterdiği tespit edilmiştir. Bu minvalde geleneksel bir metin olan Hurşîd-Nâme'nin modern hikâye ve romanla benzer tekniklerle incelenmesi gereken bir eser olarak değerlendirilmiştir. Bu çalışmada 14.yüzyıl divan edebiyatı sanatçılarından Şeyhoğlu Mustafa'nın Hurşîd-Nâme adlı mesnevisi tahkiye unsurları bakımından ele alınacaktır.The narrative, which is as old as the history of humanity, has always found the opportunity to express itself in any form. Although these genres change according to the ages, their names are sometimes fairy tales, epics, masnavi, sometimes novels, but the common point of all of them is the narration of events. Although the texts, expression styles and forms are different from each other, the basis of all the texts related to the narrative is based on an event. While the event in question is decorated with extraordinary things in the fairy tale and heroism in the epic, it is decorated with poetry in the masnavi. Masnavi, which require mastery in Divan literature, are a form of verse that divan poets apply to show their skills. Mesnevi is a type of text that is written in the form of poetry, but contains structural elements such as plot, heroes, place, time, point of view, and even expression techniques. In our thesis, we have tried to reveal the structural elements and narrative techniques of masnavis, which are partially ignored, in accordance with the classical text, without claiming to bring them closer to genres such as stories and novels. Since the events in the masnavi are far from extraordinary and livable, it has been determined that the names of the places are similar to the texts related to the narrative, considering the fact that the language used is close to the daily spoken language of that period. In this style, Hurşîd-Nâme, which is a traditional text, has been evaluated as a work that should be examined with similar techniques to modern story and novel. In this study, the masnavi named Hurşîd-Nâme of Şeyhoğlu Mustafa, one of the artists of 14th century divan literature, will be discussed in terms of narration elements
Prediction of gamma ray spectrum for 22Na source by feed forward back propagation ANN model
No full textThe radiation has been used in a variety of different fields since its discovery and thus its measurement becomes vital in these industries. Different type detector may be used to measure gamma rays depends on the purposes of measurements. Gamma ray energy spectrum is an important to determine either elemental analysing of a sample or radiation shielding purposes. On the other hand, Artificial Neural Network (ANN) may be used to predict and analysing of gamma-ray spectrum. In this study, gamma ray spectrum from 22Na source detected in NaI (Tl) detector was estimated by ANN. There have been installed ten different ANN models to find the network structure that produces the best predictive value for the gamma ray spectrum NaI (Tl) Detector. Estimation study has been continued with the ANN model with be possessed of lowest error value. ANN model was created by using energy, distance and gamma-rays energy spectrum (called Io) values. In the ANN model developed using the feed forward back propagation algorithm, were used artificial neurons two in the input layer, ten in the hidden layer and one in the output layer. For the case of present work, the experimental data was used 70% for education, 20% for validation and 10% for testing. The estimated values obtained with the ANN model were compared with the experimental results and a good correlation has been found between them (R2 = 0.99)
Implementation of Fuzzy Linear Programming Approach for More Accurate Demand Forecasting in a Make-to-Stock Company
No full textDemand forecasting is of crucial importance for make-to-stock companies because product demand is uncertain and it changes with time. Fuzzy linear programming (FLP) can be an optimum approach for such uncertain situations. In this study, the FLP model was used for more accurate demand forecasting in a make-to-stock company. Demand forecasting study was carried out according to the FLP method and linear programming (LP) method. Solutions of FLP and LP were compared in terms of imputed shortage cost, inventory carrying cost, and net profit. Results show that the applied FLP method is more advantageous than LP as it provides a 67% decrease in costs and a 15% increase in net profit

Ultra-thin reflective multifunctional polarization converter with nested circular ring-shaped metasurface-based for C- and X-band applications
No full textThis article presents a single-layer, ultra-thin and multifunctional polarization converter (PC) design using metasurface. The PC, which is proposed as a single layer, consists of a metal metasurface on the front side of a easily accessible FR-4 material and a metal termination on the back surface. The suggested PC features linear polarization (LP) characteristic within a frequency ranges of 5.21-5.41 GHz and 7.53-8.08 GHz in C-band, also 10.59-10.84 GHz in X-band under normal incidence. It indicates the conversion performance of linear polarization to circular polarization (LP-CP) that has the properties of left-handed circular polarization (LHCP) in frequency range of 5.74-7 GHz in C-band and right-handed circular polarization (RHCP) in frequency range of 8.63-10.15 GHz in X-band. Besides, the suggested PC provides more than 90% polarization conversion ratio (PCR) value in case of normal incidence (0?) and over 80% PCR value in case of oblique incidence up to 45?. Again, the suggested PC offers the same CP feature in two frequency regions where CP conversion takes place under normal incidence for angle of incidence up to 60?. A prototype of suggested PC was produced, measured, and a good match was found between the results simulated via a commercial electromagnetic (EM) simulation program. Finally, the performance of suggested design is compared with existing studies in literature with its high aspects. In this context, the suggested PC may be useful for C-and X-band applications due to its simple structure, ultra-thin and compactness, low-cost, and performance of LP and CP conversion under wide oblique angles
Seismic response of adjacent buildings interconnected by viscous dampers considering soil-structure interaction
No full textThe effectiveness of fluid viscous dampers (FVDs) on dynamic response mitigation of coupled two adjacent structures was investigated, considering soil-structure interaction (SSI) effects under earthquake excitation. A numerical procedure was employed to evaluate system response. The finite elements were used for the numerical treatment of the adjacent buildings and soil region. Viscous boundary conditions were used as special non-reflecting boundaries on the edges of finite soil region. According to the results, the FVDs were found to be very effective for dynamic response mitigation of the adjacent buildings, even if considering the soil medium. The results showed that the most affecting parameter on the system response was found to be soil type. It was also concluded that when adjacent structures coupled by FVDs, the maximum values of the roof displacements, the base shear forces, and the base bending moments could decrease up to around 50%. Changing in lateral stiffness of the one building has minor effects on the effectiveness of viscous dampers
