Approach for siting a support facility for transporting supplies in emergency cases in the Republic of Bulgaria
No full textIn this paper, the author determines the most suitable transportation location for intervention in a large scale disaster in the Republic of Bulgaria, by means of the Weber Problem and the Weiszfeld method. The objective is to minimise the cost of transporting emergency supplies across the country by locating a support facility, and thus reaching the area of event at the lowest possible cost. A brief description of the Weiszfeld method is provided in the paper. Further, using recent population data of both provinces and municipalities, the method is applied respectively to obtain the results. They were compared in terms of spatial correspondence and the final facility location was fixed. Erecting the supply site is recommended to help decrease the losses
Bibliometric analysis of the results of Reiki research
No full textIntroduction: This study analyses bibliometric indicators to assess global research trends on Reiki, including publication patterns and key contributing countries. Methods: The publications included in Web of Science (WOS) databases between 1970 and 2024 were reviewed. The WOS database was searched using TS= “REIKI” and all WOS indexes were included. This search identified 414 studies. Among them, letters (n = 7), editorial materials (n = 19), book reviews (n = 9), corrections (n = 2), art and poetry (n = 1), news (n = 1), and retracted publications (n = 1) were removed. The remaining 374 articles were included in this bibliometric analysis. The R-package for bibliometric analysis (Bibliometrix) was used. Results: The bibliometric analysis found that researchers published Reiki-related studies between 1983 and 2024, with a publication growth rate of 4.47 %. On average, articles were 9.5 years old and received 13 citations per document. The total number of keywords identified by the authors was 553, the number of authors in the articles was 1124 authors, the number of single-author articles was 70, the average number of publications per author was 3.5, and international co-authorships were 7.219 %. The USA, Brazil, the United Kingdom, Canada, and Turkiye were the top five countries that published on Reiki, respectively. The USA, Canada, the United Kingdom, Australia, and Turkiye were the top five countries with the most cited articles, respectively. Vitale A. is the most cited author. Journal of Alternative and Complementary Medicine is the most cited journal. Conclusion: This study is the first of its kind to evaluate the articles written by researchers in the field of Reiki only. Despite the difficulties researchers experienced in the field of Reiki, the studies have increasingly been conducted in this field over the years and have been cited studies more. This study may be helpful for researchers to determine productive countries, journals, authors, and emerging trends in Reiki by providing comprehensive analyses and structured information on this subject. © 202
Optimization of design parameters for Turkish Tirkes (war) bow
No full textThe bow and arrow is a projectile weapon system that predates recorded history and is common to most cultures. The Turkish bow is the most efficient one in its category. Despite of its superiority, Turkish bow is the one which is least documented in the literature. Technical drawings for the Turkish bow are missing. Turkish bow is a system consisting of different elements. Each element has its own distinctive feature and serves for a specific purpose. Recent interest in Turkish bow simply involves the replication of museum samples without any consideration about the performance characteristics of the replica. The present work aims at describing the Turkish bow, war bow known as Tirkes in specific. Characteristic shape parameters will be identified and the effect of each parameter on bow performance will be discussed. Parametric optimization to maximize bow efficiency will then be introduced. The bow shape will first be described. Characteristic shape parameters defining the bow geometry will be identified and the range in which they vary will be determined. The bow is drawn in the ANSYS (R) environment. Based on the design drawing a model bow is manufactured. Due to its superior flexing characteristics, E-glass fiber epoxy system is used in the composite structure. The model bow is tested to determine the characteristic draw weight - draw distance behavior of a typical bow. A mathematical model which is a simplified analysis of recurved bow types is used to compare behavior of model and manufactured bow draw weight - draw distance graph. Using ANSYS, bow is optimized over the related domain. Only geometrical parameters are considered. Bow length, width and thickness are varied over their domain of definition and their effect on the bow performance is investigated. Limb part is taken as the working element and is optimized for high deflection and low weight. The optimization process results in response charts showing the effect of the design variables on output. Sensitivity analyses of the input parameters resulted in the influence weight of each parameter and how each parameter affects the output. Using a goal-driven optimization approach, different design points were rate and the best design is identified. As compared to the effect of the other variable thickness is found to be the most influential variable affecting the draw weight. (C) 2014 Elsevier Ltd. All rights reserved
Religious thought: Its religious economy, transformation, and future
No full text& Idot;shak Arslan's book titled Din Dusuncesi is a distinctive and original study compared to other works on religion in Turkish literature. Rather than focusing on religion itself, Arslan employs the concept of the "religious," which he defines as a form of generalized economy between the individual and the community. According to the author, the religious is structured around a "triadic spiral" composed of sacrifice, moderation, and hope. This triad distinguishes the religious from other forms of belief and spirituality. The book discusses the relationship between religion and economy, the functions of rituals, and the transformation of religion in the modern era. While presenting hedonism as the strongest rival to religion, it does not consider atheism or deism as genuine alternatives. This review highlights certain criticisms but emphasizes that Din D & uuml;& scedil;& uuml;ncesi makes an original and creative contribution to the literature
Performance of the Whale Optimization Algorithm in Space Steel Frame Optimization Problems
No full textInternational Conference on Harmony Search, Soft Computing and Applications (6. : 2020 : Istanbul, Turkey)Frame optimization that contains highly non-linear and irregular functions and discrete design variables is one of the most challenging optimization problems. Therefore, gradient-based optimization techniques cannot be successful in such problems. Metaheuristic techniques, especially population-based metaheuristic techniques, perform highly effective in solving the frame optimization problem. However, stochastic processes’ performances included in metaheuristic techniques vary based on the problem. Accordingly, researches on the performance of novel metaheuristic techniques on challenging engineering problems continue. One of the novel metaheuristic techniques is the whale optimization algorithm (WOA) which is inspired by the bubble-net feeding behavior of humpback whales. The aim of this study is testing the performance of WOA for space steel frame optimization problems. For this purpose, WOA-cased frame optimization program will be developed. Benchmark frame structures are selected to compare optimum solutions with literature results. © 2021, The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.No sponso
Effects of curvature-Higgs coupling on electroweak fine-tuning
No full textAbstractIt is shown that nonminimal coupling between the Standard Model (SM) Higgs field and spacetime curvature, present already at the renormalizable level, can be fine-tuned to stabilize the electroweak scale against power-law ultraviolet divergences. The nonminimal coupling acts as an extrinsic stabilizer with no effect on the loop structure of the SM, if gravity is classical. This novel fine-tuning scheme, which could also be interpreted within Sakharov's induced gravity approach, works neatly in extensions of the SM involving additional Higgs fields or singlet scalars

Iron, vitamin B12 and folate play a role in body metabolism, cell division and differentiation, regulation of the immune system, bone development, perception and intelligence function by entering the structure of many enzymes. In the study, we investigated the prevalence of serum iron, vitamin B12 and folate deficiency in children. Materials and Methods: Serum iron level, iron binding capacity, ferritin, vitamin B12, folate level and complete blood count were studied in a total of 392 children aged 6-14 years who applied to the General Pediatric Polyclinic of Zonguldak Bulent Ecevit University Medical Faculty Hospital. A questionnaire including various parameters such as socioeconomic level, diet, physical development, education level was organized. Results: Our study was done with 223 girls and 169 boys, a total of 392 children. Iron deficiency (ID) was found in 60.5% of the cases, vitamin B12 deficiency in 33.4%, folate deficiency and insufficiency in 7.6%. When the cases were examined in two groups as 6-10 years (n = 211) and 11-14 years (n = 181), a statistically significant difference was found in the prevalence of vitamin B12 deficiency in adolescents (p <0.001). While folate deficiency and insufficiency were found in 10.2% of the cases with ID, it was found at a rate of 3.9% in those without ID. This difference was statistically significant (p = 0.037). Conclusion: Nutritional deficiencies may not always have clinical complaints. In our study, we found that these deficiencies were common in children. The aim should be to detect deficiencies before clinical findings appear
Probabilistic design of sheet-metal die by finite element method
No full textIn sheet-metal forming dies, highest stresses occur in bars which connect die to the frame. Considering fatigue behavior of bars with finite element method and probabilistic analyze provide many advantages predicting the life of dies in the design process. An effective and efficient design strategy is proposed to design sheet-metal die in order to reduce stress and increase fatigue life of sheet-metal die. In this strategy, finite element analysis, Approximate model, a numerical optimization algorithm and probabilistic design method Monte Carlo simulation are integrated to create an automated design tool. The reliability of the results are checked and refined by using probabilistic design techniques. Finally with the help of probabilistic design results, fatigue behaviors of the bars are predicted. At the end of the analysis process 43% volumes is gained. Stress value is 46.3% lower than the initial design. Safety factor of fatigue is reduced 36%. (C) 2007 Elsevier Ltd. All rights reserved
