One of the main reasons for this is the integration of renewable energy sources into power systems. Today, especially renewable energy sources such as wind and sun are densely connected to power systems at various points. As a result, changes occur in the structures of the power systems. These structural changes also affect the parameters of power systems. One of these parameters, voltage stability, is considered as an important criterion in terms of the quality of electric energy and the continuity of electric energy. In this study, the voltage stability analysis of the power system was made by adding the renewable energy sources to various points on six bus power system. The review focuses wind power plants heavily used in renewable energy sources. Various scenarios have added renewable energy sources at various levels to the consumption points of the power system. As a result of these scenarios, stability limit values of the power system are investigated. The study was performed through the Power World simulation program. In addition, the P-V curves of the buses are plotted with continuous load flow. According to the results obtained, it is observed that the system has improved stability limits, voltage and power.

Significant distinctions from previous epochs mark this period. Indeed, digitalism produces a transformation in every field via its specified applications, resulting in the creation of a new natural cosmos and a new human species. Unarguably, in addition to all its productions, the field in which digitalism most excels, owing to its inherent nature, is the adoption of an imaginary state of being as a database. This field, which we might refer to as the digi-image, has a significant impact on fields that can be changed into imaginary productions, such as belief, mystification, value, and culture, as well as the process of change in general. This study is a comparative and theoretical study of the new role that faiths, beliefs, and civilizations will play due to digital image transformation.

Scoring systems have been adopted to quantify the severity of the disease, but they were based on clinical findings that can vary according to the subjective assessment of the clinician. We hypothesized that diaphragm ultrasound (DUS) parameters may be a new useful tool to objectively score the severity of the disease and predict outcomes in children with pneumonia. Methods: Children diagnosed with pneumonia, aged between 1 month and 18 years, were prospectively evaluated in the pediatric emergency department. The Pediatric Respiratory Severity Score was used to indicate the severity of the disease and DUS was performed. Diaphragm thickness at the end of inspiration and expiration, thickening fraction (TF), diaphragm excursion, inspiratory slope (IS), expiratory slope (ES), and total duration time of the respiratory cycle were calculated. Results: There were 96 patients enrolled in the study. Inspiratory slope and ES measurements had positive correlations with respiratory rate and length of stay in the hospital and negative correlations with oxygen saturation levels. Furthermore, TF values were negatively correlated with respiratory rate and length of stay in the emergency department. Patients with higher clinical scores had increased IS and ES and decreased TF values. Conclusion: Diaphragm ultrasound can be a promising and useful tool to assess diaphragmatic dysfunction in patients diagnosed with pneumonia. Diaphragm parameters, especially TF, IS, and ES, may provide objective and reliable information to predict the severity of the illness, the need for respiratory support, and outcomes.

Although this method is preferred due to the high energy gain, it is criticized in some societies due to the formation of some toxic combustion products and gases and high initial investment cost. The thermal processing or pyrolysis method is a method that brings out innovative technologies and designs around the world because of environmental factors as well as economic improvements. Municipal solid wastes can be disposed by the pyrolysis method which gained popularity in recent years, by producing economical value of the obtained thermal processing liquid and syngas and also the electricity can be produced during the process. In this study, the methods aforementioned in terms of energy production from municipal solid wastes were examined and an evaluation was made for Turkey.

Despite all improvements in diagnostic techniques, there are still ongoing problems as proper diagnosis, misdiagnosis and perforated appendicitis. The aim of this study is to demonstrate the clinical value of IMA in patients with appendicitis and to determine the accurate diagnosis of appendicitis in clinically suspected patients. Methods Pediatric patients with acute abdominal pain who had the Pediatric Appendicitis Score (PAS) C 7 (n = 109) and a control group of 35 patients were included in this prospective case-control study. Patients were divided into two groups: patients with appendicitis (pathologically confirmed) (n = 78) and no appendicitis (n = 31). No appendicitis included observation patients and negative appendectomy. Serum samples were collected for routine laboratory parameters and IMA before surgery. Results Patients with appendicitis had significantly higher IMA levels than no appendicitis and control groups (p = 0.001 and p \ 0.001; respectively). Moreover, patients with negative appendectomy had significantly lower IMA levels than patients with appendicitis (p = 0.009). IMA and PAS were used together, and in the ROC analysis, we obtained 0.81 AUC for PAS and 0.89 AUC for PAS and IMA. Conclusion The current study indicated that IMA is a reliable marker for accurate diagnosis of appendicitis. The combination of IMA with PAS score has been shown to facilitate the diagnosis of appendicitis.

The measurements of a.c. magnetic susceptibility have been carried out at constant a.c. field amplitude and constant frequency for the samples studied. The temperature dependence of intergranular critical current density (J cm) has been estimated from the a.c. magnetic susceptibility data. The d.c. magnetization measurements were performed at the temperatures of 5 K, 20 K, and 77 K separately. The variation of critical current density (J c) with magnetic field (μ 0 H) has been evaluated from the d.c. magnetization data by using upper and lower branch of the major hysteresis curve. Lu substituted Y 0.5 Lu 0.5 BCO (123) sample shows higher critical current density than Yb and Dy substituted samples at low-temperature (lower than 77 K) regions.

The effects of organic manures and non-chemical weed control on grain yield of wheat were investigated during the 2006-07, 2007-08 and 2008-09 growing seasons, in Erzurum (Turkey) rain-fed conditions. The experiment contained three experimental factors in a factorial design: (1) cultivar (Doğu 88, Kırik), (2) weed control (weedy control, hand weeding, dense sowing) and (3) manure (unfertilized, mineral NP, Bio, Bio SR, Leonardit, Organic Manure, cattle manure). The modern cultivar Doğu 88 had significantly higher leaf area index, grain filling period, spikes per m 2 , kernels per spike, grain yield and harvest index than the local cultivar Kırik. On average of years, hand weeding and dense sowing increased grain yield by 9.2% and 7.7% compared to weedy control, respectively. Application of mineral NP resulted in the highest grain yield. Among the organic manures, the highest grain yield was obtained at cattle manure and Organic Manure, respectively. Cattle manure and Organic Manure increased grain yield of wheat by 25.6% and 23.2%, respectively, compared to unfertilized treatment. Improved performance in response to treatments was generally related to spikes per m 2. Doğu 88 should be preferred to local cultivar Kırik. Dense sowing appears to be a useful method to provide the wheat a competitive advantage against weeds. As a result, cattle manure can be used for improvement of grain yield of wheat and soil fertility under rain-fed conditions.

However, the effect of sympathetic predominance on left ventricular hypertrophy (LVH) in RH is not very clear. In our study, we aimed to evaluate the association between sympathetic overactivity and LVH in RH. Methods: One hundred forty-two RH patients were enrolled in this study. Transthoracic echocardiography was performed in each case and LVH parameters (interventricular septum and posterior wall thickness, left ventricular mass and left ventricular mass index) were assessed. Seventy-five patients had echocardiographic evidence of LVH (RH/LVH(+)) while the other 67 patients did not (RH/LVH(-)). Mean heart rate and time domain heart rate variability (HRV) valuesstandard deviation of NN intervals (SDNN), standard deviation of all five-minute NN intervals (SDANN), triangular indexthat reflect sympathetic overactivity were obtained from 24-hour ECG recordings. Mean heart rate and HRV values were compared between the two groups. Results: Demographic and clinical characteristics and blood pressure levels were similar between the groups. Echocardiographic parameters that reflect LVH were significantly higher in the RH/LVH(+) group than in the RH/LVH(-) group. Time domain HRV values were significantly lower (SDNN: 119.1 ± 34.6 vs. 138.1 ± 42.9, p=0.004; SDANN: 108.1 ± 41.6 vs. 127.9 ± 45.1, p=0.007; triangular index: 31.2 ± 10.5 vs. 36.3 ± 11.1, p=0.006) and mean heart rate was significantly higher (83.7 ± 16.4 vs. 78.3 ± 12.4, p=0.03) in the RH/LVH(+) group than in the RH/LVH(-) group. Conclusions: Our study showed that, among patients with RH, sympathetic overactivity is significantly higher in those with LVH.

Diğer bir deyişle yukarıda belirtilen ögelerin, müzik başta olmak üzere değişik eğitim alanlarında temel ifade aracı olarak değerlendirilmesidir. Farklı diller ve kültürlerden hareketle evrenselliği yakalayan Orff-Schulwerk yaklaşımı temel müzik eğitimi başta olmak üzere disiplinler arası bir çalışma anlayış ve programını da kendi iç dinamiklerinde ortaya koyabilmiştir. Bugün dünyanın değişik yerlerinde farklı dil ve kültürlerden hareketle evrenselliği yakalayan Orff-Schulwerk yaklaşımı Türkiye'de geç denilebilecek bir tarihte tanınmaya başlamıştır. Orf Öğretisi konusunda bugüne değin yapılanların bilinmesi, bundan sonra yapılacaklara yön verecektir. Gerek akademik çevrelerde, gerekse özel kurumlardaki uygulamaların bilinmesi, gelişimin gözlenmesi tarihsel dizin oluşturma bakımından da önem taşımaktadır. Bu araştırmada Orff-Schulwerk yaklaşımının Türk eğitim sistemi içinde bugüne değin geçirdiği süreç ele alınmıştır. Alanyazın tarandıktan sonra veri toplamak amacıyla başlangıcından bugüne Orff-Schulwerk yaklaşımı çalışmalarının içinde bulunan Muzaffer Arkan, Ali Uçan, İnci Baykara ve 2002 yılında ölen Lizoletto Sey'in deneyimlerini aktarması için Rana Uluç Sey ile görüşme yapılmıştır. Elde edilen bilgiler yarı yapılandırılmış görüşme tekniği kullanılarak yorumlanmıştır.

Therefore, surgical treatment is recommended for those fractures with 2 mm or more of displacement, or significant articular involvement with incongruency or rotation. The goal of surgery is restoration of anatomy with stable fixation. In this study we present some cases managed with internal fixation of the injury. This technique has the advantage of anatomic stable fixation with good outcome.

However, the effect of sympathetic predominance on left ventricular hypertrophy (LVH) in RH is not very clear. In our study, we aimed to evaluate the association between sympathetic overactivity and LVH in RH. Methods: One hundred forty-two RH patients were enrolled in this study. Transthoracic echocardiography was performed in each case and LVH parameters (interventricular septum and posterior wall thickness, left ventricular mass and left ventricular mass index) were assessed. Seventy-five patients had echocardiographic evidence of LVH (RH/LVH(+)) while the other 67 patients did not (RH/LVH(-)). Mean heart rate and time domain heart rate variability (HRV) valuesstandard deviation of NN intervals (SDNN), standard deviation of all five-minute NN intervals (SDANN), triangular indexthat reflect sympathetic overactivity were obtained from 24-hour ECG recordings. Mean heart rate and HRV values were compared between the two groups. Results: Demographic and clinical characteristics and blood pressure levels were similar between the groups. Echocardiographic parameters that reflect LVH were significantly higher in the RH/LVH(+) group than in the RH/LVH(-) group. Time domain HRV values were significantly lower (SDNN: 119.1 ± 34.6 vs. 138.1 ± 42.9, p=0.004; SDANN: 108.1 ± 41.6 vs. 127.9 ± 45.1, p=0.007; triangular index: 31.2 ± 10.5 vs. 36.3 ± 11.1, p=0.006) and mean heart rate was significantly higher (83.7 ± 16.4 vs. 78.3 ± 12.4, p=0.03) in the RH/LVH(+) group than in the RH/LVH(-) group. Conclusions: Our study showed that, among patients with RH, sympathetic overactivity is significantly higher in those with LVH.
