- MakaleAçık Erişim2020Investigation of the Effect of Differential Morphing on Forward Flight by Using PID Algorithm in Quadrotors
Oktay, Tugrul; Kose, Oguz
In this study, modeling, control and differential morphing of a four-rotor unmanned aerial vehicle known as a quadrotor isdiscussed. With differential morphing, the forward flight performance and model of an autonomous quadrotor is presented.Due to the complex structure of the quadrotor, it is difficult to build the model. To get model parameters, a complete quadrotormodel is drawn in the Solidworks program. In addition, Newton-Euler equations are used in the mathematical model.Simulation is done in Matlab / Simulink environment by using the parameters obtained from the model and the state-spacemodel approach. PID (proportional, integral, derivative) is used as the quadrotor control algorithm. As a result of the study,the quadrotor forward flight is carried out using PID algorithm and differential morphing. The system characteristics of thesituations with and without differential morphing are compared and the results are presented with graphs.

Burnaz, Nesibe Arslan; Akar, Zeynep
ABTS• + (2,2-azinobis- (3-ethylbenzothiazoline-6-sulphonic acid)) radical scavenging assay iswidely used to determine the antioxidant activity of natural and synthetic substances. As otherantioxidant activity determination methods, a spectrophotometer device is needed to determinethe numerical value of the color formed in ABTS method. Therefore, the dependence on thedevice is disadvantageous due to especially the high cost and restriction of workspace. Toovercome this disadvantage, a new colorimetric method in the determination of antioxidantactivity for ABTS method was developed with the help of a scanner device and free software(Image J). Mixtures (plant extracts and antioxidant standards) in this new colorimetric methodwere prepared as in the spectrophotometric method and, after the incubation period, each ofthese reagent mixtures was dropped onto the thin layer chromatography (TLC) plate. Then thecolors that appeared on the thin layer chromatography were transferred to the computer withthe help of a scanner and CSC50 values (the color value of the antioxidant concentrationrequired to scavenge 50% of the ABTS radical in the test solution using Image J software)were measured with free software of Image J. The same measurements were performedsimultaneously on the spectrophotometer. The results of both methods were compared. Therewas a strong correlation between the new colorimetric method and the spectrophotometricmethod for ABTS. Thus, the new colorimetric method for the ABTS test has become easilyapplicable since no spectrophotometer device is needed and in all environments.

Oktay, Tugrul; Kose, Oguz
Quadrotor are four-rotor unmanned aerial vehicles(UAV). These vehicles are widely used in military and civilian areas. They are preferred because they eliminate the risk of life of pilots. In this study, the effect of morphing, which is a new and developmental phenomenon in unmanned aerial vehicles, on lateral flight is discussed. Quadrotor modeling is achieved by Newton Euler approach. Models with quadrotor full and morphing states were drawn in Solidworks program. Simulations were made using the state space model approach in Matlab environment with the moment of inertia and mass values obtained in these models. Proportional integral derivative(PID) is used as the quadrotor control algorithm. Simulations are performed separately for each morphing situation. The results are presented with graphic and design performance criteria.

Baltaci, Cemalettin; Gundogdu, Ali; Duran, Celal; Bozbeyoglu, Pinar
Three adsorbents with different characteristics were produced in this study by activation of sulfuric acid with different concentrations, from corn (Zea mays L.) cobs, which is an agricultural waste by-product resulting from harvesting. After characterization by the parameters such as Boehm titration, determination of pH-pHpzc, and methylene blue – iodine number, and IR analysis, their methylene blue adsorption potentials from aqueous medium were investigated based on equilibrium, kinetics, and thermodynamics evaluations. This study aims to examine the effects of relatively dilute and concentrated acids on the activation process and to gain an economic value to waste materials through the production of a new adsorbent. It was observed that the initial solution pH did not have a significant effect on the adsorption efficiency. The adsorption process reached the equilibrium at the end of the first 120 minutes, and the kinetic data fit the pseudo-second-order kinetic model. Langmuir adsorption capacity (295.5 mg/g) of the adsorbent produced by activating with 50% sulfuric acid was found higher than those produced with 75% and 98% acids. An increase in ambient temperature effected the adsorption positively. As a result, in this study, very low-cost adsorbents were produced from the waste by-product corn cobs, and a new approach was proposed for cleaning wastewater containing dyestuffs.

Mevcut COVID-19 pandemisi’nin nedeni olan SARS-CoV-2 yeni bir virüstür. Bu patojene karşı mevcut tedavi ve bağışıklığımız bulunmamaktadır. Influenza virüsleri ise sürekli olarak evrimleşmekte ve bağışıklık sistemimiz tarafından daha az tanınabilir hale gelecek çeşitli düzeylerde antijenik sürüklenme ve kayma geçirmektedir. Bu, geniş ölçüde etkili bir grip aşısının geliştirilmesini zorlaştırmakta ve aynı zamanda yeni zoonotik influenza suşlarının ortaya çıkması pandemi riski oluşturmaktadır. Hem Coronavirüsler hem de Influenza virüsleri, zarflı RNA virüsleridir ve insan solunumunu etkileyen birincil patojenlerden biridir. COVID-19 ve Influenza enfeksiyonları benzer bulaşma yollarına ve semptomlarına sahiptir. İncelenen literatürler, COVID-19 ve Influenza arasında önemli yapısal farklılıklar olduğunu bildirmektedir. Bunlar, genom yapıları, yüzey proteinleri, suş sayısı ve alt tipleri içerir. Bunlara ek olarak, inkübasyon süreleri, risk grupları, asemptomatik bulaşma ve bulaşma hızı iki virüs arasındaki önemli farklılıklardır. Bununla birlikte, gripten farklı olarak. COVID-19 için aşı ve tedavilerin olmaması, hastalığın yayılmasını kontrol etmede ciddi zorluklar ortaya çıkarmaktadır. Sonuç olarak Coronavirüs hızla yayılıyor ve influenza virüsü ile olası ko-enfeksiyon riski nedeniyle COVID-19 ile birlikte grip enfeksiyonunun değerlendirilmesi ve buna göre halk sağlığı önlemlerinin geliştirilmesi son derece önemlidir.

Gezginci, Elif; Goktas, Sonay; Aktuğ, Cemile
The systematic review was planned to examine the application time of antibiotic prophylaxis to prevent surgical side infections. The keywords, “antibiotic application time”, “antibiotic prophylaxis” and “surgical side infections”, were searched both in Turkish and English in Google Scholar, PUBMED, and EBSCO databases. A total of 5969 studies published between 2009 and 2019 were screened. After the literature review, 5 related studies that met the inclusion criteria were included in the study. Preoperative antibiotic prophylaxis and antibiotic application times were examined. In a study included in the study, it was shown that the risk of developing surgical site infection was reduced in patients who received antibiotics for proclactic purposes 60 minutes before incision line formation. In the remaining four studies, it was stated that prophylactic antibiotherapy applied 30 minutes before surgery minimizes the development of surgical site infection. It was revealed that the application of prophylactic antibiotherapy 30 minutes before the incision line minimizes the risk of infection in the surgical area and the literature should be supported by studies on the time of antibiotic administration.

This study examined the perception levels of brand personalities and team identification of Gumushanespor spectators, and also analyzed the data in terms of various variables. The participants of this study consisted of a total of 326 spectators (166 female and 160 male) living in the center of Gumushane, Turkey. As data collection tools Sport Spectator Identification Scale and Brand Personality Scale were used. In the analysis of the data, Single Factor Variance Analysis, Correlation Analysis, and Multiple Linear Regression Analysis were used for variables determined to show normal distribution and homogeneity. On the other hand, Kruskal-Wallis Test was applied to the data that could not provide the parametric test condition. Tukey Test was used in Variance analysis, and Mann Whitney U Test was used in the Kruskal-Wallis Test for multiple comparison processes. Findings were obtained in terms of various variables in the analyzes. In addition, the results of the analysis indicated that the brand personality is a significant and powerful predictor of identifying with the team with the sub-dimensions of excitement and sophistication. However, sincerity, competence, and ruggedness variables that make up the brand personality did not make a significant contribution to this predictive model.

Beken, Hikmet Gulcin; Dobreva, J; Alaverdov, E; Yildirim-ahin, E
Launched in Brazil as of 2003, Bolsa Familia is an example of conditional cash transfer programs. Under Bolsa Familia, extending support to the poorest groups is targeted by fighting against poverty and alleviating inequality. Besides, preventing poverty from being transmitted across generations and supporting the human capital in terms of education and healthcare are also targeted. Bolsa Familia constitutes the social protection system of the country along with integration of both social insurance and social support programs. Bolsa Familia was transformed into a more comprehensive program by gathering previous programs implemented in the country under a single roof, and it allowed the government to reduce administrative costs. In this study, the focus will be placed on the effect of Bolsa Familia on the fight in the country against poverty and inequality by a theoretical analysis.

Karademir, Aysenur; Dobreva, J; Alaverdov, E; Yildirim-ahin, E
The expression of for the benefit of society or, ibadullahin terfihi ahvalleri which appeared in the court registers was a brief but nevertheless powerful summary of Ottoman economic and social perceptions. The Ottomans genuinely believed in this principle and, their whole social and economic life revolved around it. In this way, while they maintained the balance between rich and poor in social life, they benefited from Islamic pious foundations, waqfs, as a tool for delivering social projects. From education to health, the waqf institution provided all the services for the public, obviously supported by the Ottoman sultans. They built hospitals, soup-kitchens, universities and many other buildings, hayrat, under the management of waqfs, and they encouraged their families and government officials to do the same. Although the hayrat was the visual representation of the institution, waqf meant much more than just a building in the Ottoman economic and social understanding. In this chapter, I dig a bit deeper and, analyse some little-known aspects of Ottoman waqfs, specifically the waqfs of the state officials, referred to in the literature as sultanic and vizirate waqfs. The purpose of this study is to set out details from works which have analysed original archival sources and, to present a wide perspective on Ottoman waqf practice.

Bayrakdaroglu, Serdar; Tekin, Ali
Attention-deficit/hyperactivity disorder is a significant problem in children. Primarily pharmacological, educational, cognitive-behavioural and multi-model intervention techniques are used to treat this disorder. The success level differs with advantages and disadvantages of each technique and any single technique is not sufficient. In recent years, the positive aspects of physical exercise used in treatment alone or in combination with other techniques has made the different types of physical exercise worthy of investigation. This review aims to summarize the scientific evidence obtained through literature on the effects of defense sports in the treatment of attention-deficit/hyperactivity disorder in children. The results showed that the most beneficial sports are Taekwondo, Karate, Judo and Tai Chi. There are studies supporting the positive effect of the use of defense sports in treatment with few exceptions, but it is quantitatively insufficient. Therefore, new studies are needed to test the effect of different defense sports on a sufficient number of different samples representing the related population.

It is aimed to investigate the effects of explosive strength training on aerobic capacity, anaerobic capacity, blood pressure, resting heart rate and shooting speed. The aim of this study was to investigate the explosive strength training on some physical and physiological parameters. The study included 38 volunteer 1st and 2nd amateur league footballers aged 1825 years. Aerobic capacities of the players were measured by shuttle run test and Anaerobic power measurement by vertical jump test. After calculating the vertical jump value of the athletes anaerobic strength; calculated using the Lewis Nomogram using vertical jump and body weight values. The shooting speed of the players was determined by speed pocket radar equipment In the study, different strength training (station training method) and football-specific technical and tactical training programs were applied to the research group for 8 weeks, 3 days a week. only technical and tactical training programs were applied to the control group. The parameters were taken twice before and after the 8-week study. In order to determine the differences between the pre-test and post-test results, The Wilcoxon test, one of the nonparametric tests, was used to, Mann Whitney U-test analysis was used to compare the pre-test and post-test values between the groups. The significance level of the study was accepted as p<0.05. Significant difference in shooting speed was found as a result of the signed ranks test comparing the pre-test and post-test measurements of the research group participants (p<0,05). Significant differences between the measurements of aerobic power, anaerobic power were found as a result of the signed ranks test comparing the pre-test and post-test values of the control group participants (p<0,05). After the Mann-Whitney U test, where the posttest measurement values of the experimental and control group participants were compared, there was a significant difference between the groups in aerobic power values, and this difference was found to be in favor of the experimental group participants (p <0.05). As a result, it can be said that explosive strength training applied to amateur football players between the ages of 18 - 25 increases the shooting speed.

Purpose Acute pulmonary embolism (APE) is a life-threating cardiothoracic thromboembolic emergency in which right ventricle dysfunction (RVD) is a major concern. In the present study, we examined the hepatic veins (HVs) blood flow with pulsed-wave spectral Doppler ultrasonography to determine its relationship with the simplified pulmonary embolism severity index (sPESI) and the patient's RVD status. Methods We divided the 243 patients who met the inclusion criteria into two groups based on both their sPESI scores and their RVD status. Transthoracic echocardiography was performed to evaluate the RVD and the HVs within 1 hour after patient admission. The liver was evaluated using subcostal and intercostal echocardiographic windows in grayscale B-mode, and HVs were assessed using color and spectral Doppler assessment though the same echocardiographic windows. Result A cut-off value of the systolic reverse flow velocity-time integral (SrVTI) = 2.2 cm carried a sensitivity and specificity of 84.29% and 74.89%, respectively, for the prediction of sPESI >= 1. A SrVTI cut-off value of 2.1 cm yielded a sensitivity and specificity of 83.03% and 73.91%, respectively, for the prediction of RVD. Conclusion HV Doppler assessment could be a useful method for anticipating the sPESI and the presence of RVD in patients with APE. In addition, it may provide information regarding the hemodynamic impact of APE.

Aim: The purpose of this study was to investigate the protective effects of ethyl pyruvate (EP) and dimethyl sulfoxide (DMSO) on ischemic tissue in brain and cardiac and hepatic tissues in experimentally induced carbon monoxide (CO) intoxication. Material and Methods: Thirty-five mature female Sprague Dawley rats were randomized into five groups of seven animals each. Group 1 received no CO or treatment. Rats in groups 2, 3, 4 and 5 were made to inhale a high-concentration 5000 ppm CO gas mixture for 60 min at 4 L/min. CO levels were then measured from 1 mL tail vein blood. Group 2 received no therapeutic agent, group 3 received 6 mg/kg intraperitoneal (ip) DMSO, group 4 received 50 mg/kg ip EP, group 5 received 50 mg/kg EP and 6 mg/kg DMSO ip. All rats were sacrificed by decapitation. Brain, cardiac and hepatic tissues were removed and histopathological scores were compared. Results: Comparison of group 2 with group 3 and group 2 with group 5 revealed that DMSO alone and EP + DMSO exhibited a reducing effect on degree of cerebral neuronal alteration, degenerative neuron rates, and total cardiac injury score (p=0.005, p=0.002, p=0.004 and p=0.002, p=0.001, p=0.004 respectively). There was no histopathological difference between group 2 and group 4 suggesting EP alone had no therapeutic effect on histopathological injury. Conclusion: Based on our study findings, EP administered alone exhibited no protective effects on the organ injuries investigated, while DMSO exhibited reducing effects on degree of neuron alteration, rates of degenerative neurons, and total cardiac injury scores. An ameliorating effect on cardiac and hepatic injury was more prominent with combined treatment.

Objective Studies focusing attention on the effects of environmental pollution on the etiology of multiple sclerosis (MS) are on the increase. The aim of this study was to determine MS prevalence in a city home to an iron and steel factory which causes air pollution. Methods The study was designed as a cross-sectional, population-based, descriptive epidemiologic study. Eregli city, which has an iron and steel factory and proven air pollution, was screened. Additionally, Devrek city, which is a rural and clean city, located 40 km away from Eregli was assigned and results were compared. A validated questionnaire was used for screening. McDonald 2010 criteria were used to diagnose cases. Results 32 261 people were screened in Eregli, and 21 963 people were screened in Devrek. In total, 41 patients were diagnosed with clinical definite MS. Crude prevalence was found to be 96.1/100 000 in Eregli and 45.5/100 000 in Devrek. The mean age of patients was 39.8, and the female/male ratio was 1.9. Conclusion The results of this study indicate a more than double MS prevalence rate in the area home to an iron and steel factory when compared to the rural city. This supports the hypothesis that air pollution may be a possible etiological factor in MS.

Introduction Acute pulmonary embolism (APE) is a cardiothoracic thromboembolic emergency at risk of life-threatening. Several risk graduation algorithms may be applied to delineate short-term mortality in patients with APE. In this study, we aim to depict the relationship between the right ventricular early inflow-outflow (RVEIO) index, which is a Doppler-based parameter, and the pulmonary embolism severity index(PESI) in acute pulmonary embolism. Methods In the presented study, a total of 160 patients who were diagnosed with APE using pulmonary computed tomography angiography or ventilation/perfusion scintigraphy were comprised. Patients were separated to 2 groups based on the simplified PESI (sPESI): sPESI < 1 (n = 88) and sPESI >= 1 (n = 72). Echocardiographic parameters, including the RVEIO index, were measured. Results There were no significant differences between the groups in age and gender distribution, or the presence of diabetes mellitus, hypertension, smoking, and history of coronary artery disease. There was a positive correlation with the mortality rate and RVEIO index; the mortality was higher in patients with a higher RVEIO index(<0.001). In receiver operating characteristic (ROC) curve analysis using a cutoff level of 14.39, RVEIO index predicted mortality with a sensitivity of 80.4% and specificity of 57.6%(ROC area under curve:0.694; 95%CI, 0.581-0.814; P < .001). RVEIO index was higher in the sPESI >= 1(n:72) than in the patients with sPESI < 1(14.27 +/- 2.13 vs 10.63 +/- 2.09; P < .001). There was a positive correlation between RVEIO index and sPESI score(+0.428; P < .001). Conclusion As well as predicting the degree of tricuspid regurgitation (TR), the RVEIO index is well-correlated with sPESI score and is associated with mortality in patients with APE. This easily measurable parameter may be used to predict short-term mortality in APE patients.
