    The effect of surface roughness and carburized depth on wear resistance in 16MnCr5 case hardening steel
    Baykara, C; Atik, E
    Purpose - Today, wear and tear is a metaphor whose cost cannot be ignored by real sector. For this reason, many sectoral and academic studies are carried out to minimize the wear effect. This study aims to create a perspective against wear problems for the automotive industry as well. Design/methodology/approach - The 16MnC5 material, which is used as the U-joint material in the powertrain of the automotive industry, was subjected to heat treatment such as normalization and carburization at certain temperatures and duration. By subjecting the resulting carbide thickness to the abrasion process, the maximum effective heat treatment parameters against wear were determined. Findings - It has been determined that the ideal cementation condition for 16MnCr5 steel to be used in the wear system is carburized samples at 900 degrees C for 3.5 h with a hardness depth of 1.04 mm. Originality/value - The variation in which the surface hardness thickness and surface roughness obtained by different heat treatment variations of the U-joint part, which is one of the cardan shaft components that provide power transmission of heavy commercial vehicles, show the best wear resistance, were investigated. As a result of this study, the study is to prevent the waste of limited materials in the world and to reduce the repair and maintenance costs of commercial vehicles.

    Sarikabak, M; Ayranci, M; Yaman, C; Hergüner, G; Tok, S; Kir, R; Cana, H; Baykara, C; Dönmez, A; Genç, HI
    Aim: The aim of this study is to investigate the role of age and gender in examining the emotional intelligence levels of athletes. Methods: The universe of the research consists of licensed athletes in Turkey, and the sample consists of 2736 licensed athletes who continue their active sports life in 2019. As a data collection tool in the research; Voluntary Participation Consent Form and Personal Information Form were used. The Schutte Emotional Intelligence Scale, developed by Schutte et al., (1998), edited by Austin, Saklofske, Huang, and McKenney, (2004), and adapted into Turkish by Tatar, Tok, and Saltukoglu (2011), was used to measure emotional intelligence. SPSS 25 package program was used for the statistical analysis of the data, and descriptive statistics, one-way ANOVA and t-test analyzes were used in the analysis of the data obtained. Results: As a result of the analysis, it was seen that there was no significant difference in the comparison of the emotional intelligence sub-dimensions and the total score according to the type of sport they do (p>0.05). According to the age variable of the athletes, between the emotional intelligence sub-dimensions and the total score; there was a statistically significant difference in optimism/mood regulation, use of emotions sub-dimension and emotional intelligence total score (p<0.05). In the sub-dimension of evaluation of emotions, there was no statistically significant difference (p>0.05). Conclusion: When the emotional intelligence levels of the athletes were examined according to the gender variable, it was observed that there was a significant difference in favor of women in the use of emotions, evaluation of emotions and total emotional intelligence scores (p<0.05). The results were discussed in the light of the relevant literature and suggestions were made for future studies.
