A new approach on the development of a nonlinear model for micro pelton turbines

In this study, a new approach that is closer to the real turbine without abandoning the advantages of nonlinear modeling simplicity compromising the simplicity of the nonlinear model is proposed. The purpose of the study is to contribute to making theoretical studies of microhydroelectric power plants (MHPPs) more realistic. Studies on their control, especially frequency control, have increased with the expansion of grid-connected power plants. However, some problems have occurred when converting simulation studies of the frequency control to practical studies. The reasons for these problems are that the systems cannot be modeled completely. In this study, first, the nonlinear model equations of a Pelton turbine are primarily constituted. The efficiency curve of the turbine is then obtained experimentally and added to the nonlinear model. The simulation results are compared with the data obtained from the prototype MHPP with a Pelton turbine developed in the laboratory. Finally, it is seen that the proposed method is successful. Thus, with the help of the proposed method, theoretical studies that researchers do can be easily converted into practical applications.FÜBAP (Project No: MF.11.06)

Synthesis, crystal structure and spectroscopic studies of a new silver complex derived from [1-(3-pyridinyl) ethanone]

In this work, a new silver (I) complex, [Ag(3-pye)2(H2O)](NO3) where 3-pye=1-(3-pyridinyl) ethanone, has been synthesized and characterized by elemental analyses, FT-IR, fluorescence spectroscopy, and single X-ray crystallography. The X-ray diffraction analysis revealed that the Ag(I) complex crystallized in the monoclinic system with the C2/c space group. Computational studies were performed using DFT approache on the present complex to get insight into the structural parameters, spectral characteristics and electronic properties. The characterization results were found to be consistent with the proposed structure of the complex, and the DFT approach supported the experimental results. Also, Hirshfeld surface analysis was used to identify the non-covalent interactions within the crystal structure as well as to visualize the conformity of the crystal structure

Bariatrik cerrahi sonrası viseral organ yağ infiltrasyon değişikliklerini izlemenin etkili yöntemi: İdeal IQ sekansı

Aim: The aim of this study is to demonstrate the efficiency of non-invasive imaging method-MR proton density fat fraction (PDFF); ideal IQ sequence- on detecting the effects of bariatric surgery on liver and pancreatic fatty infiltration. Materials and Methods: Thirty-nine patients (25 females, 14 males) who underwent bariatric surgery between May 2016 and April 2017 were analyzed retrospectively in this study. Body mass index (BMI) and body weight (BW) values of all patients were noted one week before and one month after bariatric surgery, and meanwhile an unenhanced upper abdominal MR imaging was performed. Liver fat fraction (LFF), pancreas fat fraction (PFF), liver volume (LV) and craniocaudal length of liver (LL) were measured with MR-PDFF and T2 weighted images. Changes in all parameters after the surgery were recorded and the correlation of these changes with the change in LFF was analyzed. Results: At the end of first month of bariatric surgery, a significant decrease on mean values of LFF and PFF has been observed along with a decrease of LV, LL, BW and BMI (p<0.0001). A moderate positive linear correlation was observed between LFF and PFF, LV, LL (r=0.69, 0.61, 0.49; respectively) while a weak positive linear correlation was noticed between LFF and BMI, BW (r=0.34, 0.21; respectively). Conclusion: Ideal IQ sequence enables quantitative analysis of fatty infiltration of the liver and pancreas and thus may be used as a non-invasive tool to monitor the positive effects of the bariatric surgery on fatty infiltration of these visceral organs in the postoperative period.Amaç: Bariatrik cerrahinin karaciğer ve pankreas yağ infiltrasyonu üzerindeki etkilerinin saptanmasında non-invaziv görüntüleme yönteminin-MR proton dansite yağ fraksiyonu (PDFF); ideal IQ sekansı-etkinliğini göstermeyi amaçladık. Gereç ve Yöntem: Bu çalışmada Mayıs 2016 ile Nisan 2017 tarihleri arasında obezite cerrahisi geçiren 39 hasta (25 kadın, 14 erkek) retrospektif olarak incelendi. Tüm hastaların vücut kitle indeksi (VKİ) ve vücut ağırlığı (VA) değerleri bariatrik cerrahiden bir hafta önce ve bir ay sonra kaydedildi ve bu esnada kontrastsız üst abdomen MR görüntülemesi yapıldı. MR-PDFF ve T2 ağırlıklı görüntülerle karaciğer yağ fraksiyonu (KYF), pankreas yağ fraksiyonu (PYF), karaciğer hacmi (KV) ve karaciğer kraniyokaudal uzunluğu (KKU) ölçüldü. Ameliyat sonrası tüm parametrelerdeki değişiklikler kaydedildi ve bu değişikliklerin KYF’deki değişiklik ile korelasyonu analiz edildi. Bulgular: Bariatrik cerrahinin 1. ayının sonunda KYF ve PYF ortalama değerlerinde anlamlı azalma ile birlikte KV, KKU, VA ve VKİ’de azalma gözlendi (p<0,0001). KYF ile PYF, KV, KKU arasında orta derecede pozitif bir doğrusal korelasyon gözlenirken (sırasıyla r=0,69, 0,61, 0,49), KYF ile VKİ, VA arasında (sırasıyla r=0,34, 0,21) zayıf bir pozitif doğrusal korelasyon fark edildi. Sonuç: İdeal IQ sekansı, karaciğer ve pankreasın yağ infiltrasyonunun kantitatif analizini sağlar ve bu nedenle postoperatif dönemde bariatrik cerrahinin bu viseral organların yağ infiltrasyonu üzerindeki olumlu etkilerini izlemek için non-invaziv bir araç olarak kullanılabilir

Mini clinical evaluation exercise in undergraduate dermatovenereology education: An experience of University of Pamukkale, Medical Faculty

Background and Design: Mini Clinical Evaluation Exercise (Mini-CEX) is being widely used in medical education and is a reliable and valid method for the assessment of residents' competency in medical interviewing, physical examination, humanistic qualities/professionalism, clinical judgment, counseling skills, organization, and efficiency. In order to enhance formative evaluation methods in our faculty, we planned to apply the method to students on dermatovenereology training. Materials and Methods: The Mini-CEX was performed by residents to 42 medical students. At first, 5 residents were evaluated by a faculty member with Mini-CEX and were informed about their application-oriented evaluator roles. The students were informed prior to conducting the assessment. Standard Mini-CEX form was used for the assessment. The participants were rated in 7 competencies and each was rated using a 9-point Likert scale. At the end of each encounter, students and evaluators rated their satisfaction with Mini-CEX using a 9-point Likert scale. Student's t-test and one-way ANOVA were used for statistical analysis. Student feedback was evaluated with "grounded theory". Results: A total of 50 assessments, 44 in outpatient and 6 in inpatient clinic, were performed. Satisfaction with the Mini-CEX was rated by the evaluators and the students as 7,16 and 7,98, respectively. There was no significant difference between the evaluators in terms of student satisfaction. Average time spent on observing the encounter and in giving feedback was 16.5 and 6.5 minutes, respectively. There was no significant difference between assessors in terms of time spent observing and giving feedback. Average scores of assessed clinical competencies were between 4,28 and 8,14. The highest scores were reported on humanistic qualities/ professionalism whereas the lowest were reported on clinical judgment skills. Discussion: According to our data, we believe that Mini-CEX may be used as an assessment tool in medical education. However, further researches should be carried out by different observers for Mini-CEX to be a part of medical education program
