THE AGGRESSION LEVELS OF STUDENTS AT SCHOOLS THAT ADMIT STUDENTS WITH THE SPECIAL TALENT EXAM

This study aimed to determine the aggression levels of the students studying at schools who admit the students with the Special Talent Exam and evaluate the changes. The universe of the study consisted of the schools who admit the students with the special talent exam, the sample group also consisted of total 413 students including 226 males, 187 females studying at the Faculty of Sport Sciences (SBF) (n=148), the Dilek Sabancı Conservatory (DSK) (n=112) and the Faculty of Fine Arts  (GSF) (n=153). In collection of data, the 7 point Likert Aggression questionnaire by Kiper (1984), for socio-demographical information, personal information forms were used. In our study, the Cronbach alpha value of aggression scale was found to be 0.79. By testing homogeneity and variances of data, the One Way ANOVA for multi comparisons and the Tukey test for the determination of difference resources were utilized while the Independent Sample t test was used for the gender factor in the determination of relevant data changes. The statistically significant differences were found out in the sub-dimensions of Impulsive, Destructive and Passive Aggressions among the students at the Faculty of Sport Sciences and the Dilek Sabancı Conservatory and the Faculty of Fine Arts (P<0.05). In accordance with gender, age and accommodation situations, there were meaningful differences in the aggression sub-dimensions between the schools (P<0.05). Gender-based passive aggression and general aggression differences may be explained with the roles attributed to male and female individuals by society, furthermore, the students at the Faculty of Sport Sciences had higher averages in the aggression sub-dimensions rather than the other school students, which may be related.   Article visualizations

Effect of slaughter age and muscle type on selected meat quality traits and fatty acid composition of Lindovskaya geese

The study was conducted in order to determine how the slaughter age (SA) and muscle type (MT) affect technological properties and fatty acid composition (FAC) of meat among Linda geese reared under the breeder conditions. A total of 16 male geese were slaughtered in order to determine the technological properties and FAC of meat. It was determined that the effect of SA on pH(15) and pH(24) (TM), water holding capacity (WHC), cooking loss (CL), and drip loss (DL) of the thigh muscle was all statistically significant (P < 0.05). The effect of SA on pH(24), WHC, CL, and the 168th-hour DL of pectoral muscle (PM), was statistically significant (P < 0.05). Moreover, the effect of MT on pH(15), pH(24), WHC, CL and DL in the 12th week and on pH(15), pH(24), WHC and DL in the 16th week was found to be statistically significant (P < 0.05). Additionally, the effect of SA on monounsaturated fatty acid (Sigma MUFA) of TM and polyunsaturated fatty acid (Sigma PUFA) of PM and Sigma omega-6 ratios was statistically significant (P < 0.05). Consequently, it was concluded that SA was better in the 12th week than the 16th week and PM was better than TM. The 16-week TM was better in terms of Sigma MUFA, the 12-week PM was better in terms of Sigma PUFA and Sigma omega-6, and the 12-week TM was better in terms of Sigma omega-3 amount and omega-6/omega-3 ratio. Therefore, it can be recommended that 12-week-old Linda geese be selected in terms of selected meat traits and FAC of meat

THE STYLES OF COPING WITH STRESS AMONG THE STUDENTS STUDYING AT THE SCHOOLS WHICH ADMIT THE STUDENTS WITH A SPECIAL TALENT EXAM

The purpose of the research was to determine the styles of coping with stress among the students studying at the schools which admit the students with a special talent exam. The scope of the research involved the schools which admit the students with a special talent exam, the sample group included total 413 students; 226 males, 187 females, having education at the Faculty of Sport Sciences (SBF), the Dilek Sabancı Conservatory (DSK) and the Faculty of Fine Arts (GSF) in Selçuk University. Firstly, a personal information form and the Ways of Coping Questionnaire (WCQ) developed by Folkman and Lazarus (1980) and created as a short form by Şahin and Durak (1995) were used. By testing the homogeneity and variance of data, the Independent Sample t-test for the gender factor, the One Way Anova for multiple comparisons, the Tukey test for the resources of differences were applied. The Cronbach alpha value was determined to be 0,76 for the Coping Questionnaire. Depending on the gender factor; statistically significant differences were observed in all of sub-dimensions to cope with stress among the SBF, DSK and GSF students (P&lt;0.05). Given the school types, there was a lower point in the SBF student averages concerning the desperation dimension rather than the other two schools as there was a higher average in the Conservatory students’ optimism dimension rather than the other two schools, a lower average in their social support points, these differences were regarded to be statistically significant (P&lt;0.05). In accordance with the school type, differences between active and passive coping strategies did not have stable changes and any specific situation was not observed in the school type. This situation can result from the specific exam criteria and the ability and measurement techniques of the schools which admit the students with a special talent exam.  Article visualizations

HIGH SCHOOL STUDENTS’ VIOLENCE TENDENCIES

This paper aimed to compare the levels of violence tendency in three different types of high schools. The universe of the research consisted of the high school students in the province Konya, the sample group involved 280 male, 224 female students studying at the Vocational, Anatolian and Sport High Schools. In obtaining data, a personal information form and the Violence Tendency Scale (VTS) developed by Göka et al. (1995) were used. The scale was made up of a four-point Likert type with 20 questions, varying from (1) “absolutely inappropriate” to (4) “absolutely appropriate”. The highest point from the scale was “80”, the lowest point was “1”. A high point shows that the students’ aggressiveness and violence tendencies are more. In accordance with the students’ points from the scale, the point between 1-20 as “very poor”, the point between 21-40 as “poor”, the point between 41-60 as “good” and the point between 61-80 as “very good” were regarded in terms of violence tendency, the “Cronbach Alpha” reliability coefficient of the scale was found to be .88. By testing the homogenity and variance of data, in the determination of statistical differences Independent t-test, One Way Anowa, Tukey-HSD tests were utilised. In this paper, the male students’ violence tendency averages were higher rather than the female students and this difference was statistically significant (P&lt;0.05). The values regarding the students doing sportive activities were lower than the students not doing sport and this difference was statistically significant (P&lt;0.05). Depending on the factors of father and mother’s education level, income level and class, any statistical differences were not observed. The Sport High School students’ violence tendency averages were lower than two other school types, the difference between the sport high school and the vocational high school was statistically significant (P&lt;0.05). In conclusion, the students who give importance to sportive activities in their lives and have sportive education, are considered to have lower violence tendency rather than the students at other schools.   Article visualizations

Promoting photo-fenton catalytic performance of novel NiZrO3-type perovskite: Optimization with response surface methodology

Perovskite type NiZrO3 photocatalysts were synthesized by ball-mill technique and used for tetracycline (TC) degradation. NiZrO3 milled for 6 h (NiZrO3-6h) had significant-99 % photo-Fenton catalytic activity on TC removal It was determined that the characteristic peaks of NiZrO3 with XRD, spherical shaped structures with SEM, no organic peaks in the structure with FTIR, band gap of 4.40 eV with DRS and stable colloids with zeta potential. Response surface methodology (RSM) including Box-Behnken design (BBD) was applied to examine H2O2, Fe2+ and initial TC concentration effects on degradation and it was observed that H2O2 concentration had the highest effect on TC degradation. The photocatalytic efficacy of NiZrO3 could still eliminate 78 % of initial antibiotic molecules after eight-cycle. The application potential for Photo-Fenton assisted NiZrO3-6h was also observed in the degradation of other organic pollutants such as drugs (salicylic acid, ciprofloxacin, ampicillin) and dye (methylene blue, rhodamine-b, orange-II, malachite green, crystal violet). It suggests that the mechanochemically synthesized NiZrO3-6h perovskite could be suitable for its effective use in the photo-Fenton catalytic system

Vacuum carbothermal synthesis of TiB2

Abstract: In this study, the formation conditions of TiB2, whose main production method is carbothermal reduction, at lower temperatures with additional processes (vacuum, mechanical activation and functional addition effect) were investigated. In this study, firstly the 100% stoichiometric mixture was reduced at 1200°C under vacuum for varying experimental durations. Afterwards, the effect of mechanical activation amount on TiB2 formation was determined by keeping the 4-h reduction time, which was determined as optimum in the first set of experiments. At the last stage of the experiments, the addition of 2.5 and 5% NaCl effect on the mixtures in the first set of experiments was determined. The samples obtained after the experiment were characterized by XRD and SEM techniques, and it was observed that the undesired phases were completely removed as a result of the reduction performed after 16 h of ball mile operation, and this experiment was determined as the optimum experimental condition.Yalova Universit

Flue gas desulfurization by using calcined dolomite

SO2 emissions has begun to cause serious problems in industrialized countries. Today, various methods are used for removal of SO2 gas. SO2 gas is an important raw material for production of sulfuric acid. However, SO2 content of flue gas must be over 6% to produce sulfuric acid commercially. Flue gases, which don't have enough amount of SO2 to produce sulfuric acid commercially are harmful to the environment and human health and they must be filtered. In this study, calcined dolomite was used to remove SO2 in flue gas which doesn't have enough SO2 to produce sulfuric acid but have high emission values. Pyrite was used as SO2 source and SO2 removal efficiency of dolomite was determined for different experimental parameters. SO2 capturing system was thermodynamically modeled and SO2 capturing efficiency was determined as 77.81% in the experiments

Biodegradable implant materials

Implants are medical devices that have critical importance for human health. The functions expected from implant materials have increased with the advancement of medicine and engineering. Implants are used for different purposes in different areas of the body. While some implants must be permanent in the body to fulfill their duties, some implants must be removed from the implanted area after a certain period. If an implant is to be removed from the relevant area after a certain period, an operation is required for this and then, there will be a healing process. The use of biodegradable implant materials eliminates the need for this additional operation. Biodegradable materials leave their place to the tissue gradually in a certain period. Biodegradable implant materials are one of the popular research areas today and many studies are carried out in this field every year. In this chapter, information about implants, biomaterials, biodegradability concept, biodegradable metals, and biodegradable polymers is shared. Also, examples of the use of biodegradable materials in biomedical applications are included

Hydrometallurgical nickel and cobalt productıon from lateritic ores: Optimization and comparison of atmospheric pressure leaching and pug-roast-leaching processes

Corresponding to the technological developments, production and consumption of nickel have increased greatly over time due to its unique mechanical and chemical properties. Therefore, the production of nickel will always keep its importance. The availability of laterite ores, which are oxide type ores, is 86% of the nickel reserves on the Earth, and the processes used in the production of nickel from sulphide type ores have negative environmental effects. Therefore, recovery of nickel from lateritic ores has become increasingly important in recent years. In this study, the aim was to determine the optimum parameters of nickel and cobalt production from limonite type lateritic nickel ores, which were taken from Manisa Caldag region of Turkey, using atmospheric pressure sulfuric acid leaching and pug-roast-leach process. When the results obtained in these processes were compared, it was found that the Ni leaching efficiency is nearly 8% higher and iron leaching efficiency (contamination) is nearly 4% lower in the pug-roastleach process. Furthermore, the pug-roast-leach process was completed in 33% lower time compared to the atmospheric pressure sulfuric acid leaching process

Solvent-free mechanochemical synthesis of TiO2-ethyl cellulose biocomposite for adsorption of tetracycline and organic dyes

In the study, polymeric-metal oxide hybrid composite was synthesized by mechanochemical method in ball-mill by adding different amounts of TiO2 to ethyl cellulose (EC) and its potential in tetracycline (TC) removal from aqueous solutions was investigated. In order to investigate the adsorption capacity, isotherm, kinetic and thermodynamic parameters of the adsorption process, the amount of adsorbent, contact time, solution pH, temperature effect, inert electrolyte effect and different water environment effects were experimentally carried out in batch adsorption experiments. The adsorption capacity of all sorbents was conformed according to the Freundlich isotherm model and the maximum capacity is found for 80%TiO2@EC with 23.26 mg g−1. The system reached equilibrium with 89% TC removal in 480 min and complied with the pseudo second order kinetic model. In the pH effect experiments, maximum TC removal found in pH:6. Thermodynamic parameters indicate that TC adsorption on 80%TiO2@EC is endothermic and spontaneous. Different water medium and inert electrolyte effect were found compatible with each other. Also, a decrease was observed in the specific TC removal in the presence of any ions in the system. The removal of methylene blue (MB) and malachite green (MG) azo dyes as another organic environmental pollutant was also studied and their adsorption capacities were found as 105.7 mg g−1 and 109.9 mg g−1, respectively. XRD, FTIR and SEM analyzes were performed to explain the interaction mechanism between sorbent samples and TC
