ON A GENERALIZED alpha-ADMISSIBLE RATIONAL TYPE CONTRACTIVE MAPPING

Recently, many generalized contractive conditions which involve rational contractive inequalities have been introduced in the context of partially ordered metric spaces. In this paper, we aim to give a generalized rational contractive condition which involves some of these results without need of extra restrictions

Doğu Karadeniz bölgesindeki miadında gebe kadınlarda anemi sıklığı ve bazı hematolojik parametrelerin analizi

Objective: Pregnancy induces a variety of physiological changes in the hematological system. Pregnant women are in the high-risk population for iron deficiency anemia because of increased iron requirement. Thrombocytopenia affects 6-10 % of all pregnancies. In pregnant women, the hematological regional disparities may be related to the differences in feeding habits. In our study, we aimed to determine the frequency of anemia, thrombocytopenia and changes of some other hematological parameters in pregnant women in the East Black Sea Region. Materials and Methods: A total of 2584 pregnant women over 38 gestational weeks, who were admitted to our obstetric clinic between 01.01.2011 and 31.12.2012 were included in this study. Hemoglobin, hematocrit, red blood cell, leucocyte and platelet levels, mean corpuscular volume, mean platelet volume measured in the third semester of pregnancy were all retrospectively investigated. Results: The mean age of the pregnant women was 29.09±5.81 (16-48 years). The prevalence rates of anemia and thrombocytopenia were 50.3 % and 9.3 % respectively. The prevalence rates of leucocytosis and leucopenia were 10.9 % and 1.1 % respectively. The mean ages of the patients with thrombocytopenia were found to be statistically significantly higher than those without thrombocytopenia. Conclusion: During pregnancies, anemia is still a common and important public health problem for women living in the East Black Sea Region, despite routine use of iron medication. Also obstetricians should pay more attention to thrombocytopenia in pregnant women of advanced age. © 2015, Logos Medical Publishing. All rights reserved

Microstructure Characterization of WCCo-Mo Based Coatings Produced Using High Velocity Oxygen Fuel

The present study has been carried out in order to investigate the microstructural properties of WCCo-Mo composite coatings deposited onto a SAE 4140 steel substrate by high velocity oxygen fuel (HVOF) thermal spray. For this purpose, the Mo quantity added to the WCCo was changed as 10, 20, 30 and 40 wt. % percents. The coatings are compared in terms of their phase composition, microstructure and hardness. Phase compound and microstructure of coating layers were examined using X-ray diffractometer (XRD) and scanning electron microscope (SEM). XRD results showed that WCCo-Mo composite coatings were mainly composed of WC, W2C, Co3W3C, Mo2C, MoO2, Mo and Co phases. The average hardness of the coatings increased with increasing Mo content.</span

Experimental and Numerical Shortest Route Optimization in Generating a Design Template for a Recreation Area in Kadifekale

As cities grow, their complexity and the complexity of their infrastructure for various applications increase. Especially, transportation design is usually a very cumbersome process in current urban development models, and it is becoming more complex. Traditional approaches are not always sufficient to solve such complex problems, therefore, design disciplines like architecture and urban design need new tools to optimize many parameters related to their design. An alternate way to solve this problem can be via finding shortest routes. In this context, this study aims to evaluate different shortest path algorithms within a methodological approach to urban transportation planning via either experimentation or mathematical modeling. Three methods; namely live slime mold plasmodium, Floyd-Warshall algorithm, and ant colony algorithm are used to design a template for routes within the historical Kadifekale district of Izmir, Turkey. The results from these approaches are compared, contrasted, and discussed in terms of their suitability for use as a guide for route creation. In conclusion, the parameters of an algorithm are significant on suggesting routes, thus the strengths and weaknesses of an algorithm should be carefully considered before application in a design problem
