Ustabulut, Mete Yusuf; Keskin, Savaş
This study tries to map educational processes that have to be transformed into the extraordinary history of the COVID-19 pandemic and adapt to the ‘new normal’ with a relational and metaphoric approach. In the study, the existing physical and mental conditions of the students who are "scattered/dispersed" geographically due to the mandatory "return home" in the pandemic process are conceptualized with the metaphor of the "diaspora". The study aims to draw attention to student-centered social problems by questioning the functionality of tele-education processes, which are designed to compensate for interrupted educational relationships and make them sustainable again. It is aimed to measure the effects of online consciousness that were deterritorialized by human-computer interaction and computer-mediated communication on student performances and to understand student motivations during the tele-education process. Therefore, a survey was conducted at ten universities in Turkey and reached 150 students through the snowball sampling technique. The results of the study show that the student self-perception of the tele-education process coincides with the diasporic identity and this unusual technology integration that cannot be fully compensated triggers mental diaspora feelings.

Sert, Durmuş; Mercan, Emin
The effects of churning with different concentrations of ozonated water (OW) on fat particle size, texture, oxidation, melting and microbiological characteristics of butter from raw cream were investigated. For this purpose, butter samples were produced by churning with ozonated waters at concentrations of 0 (control), 0.15 (OW-15), 0.20 (OW-20), 0.25 (OW-25) and 0.30 (OW-30) mg L−1. Churning with OW increased the lightness and redness value of samples and decreased yellowness. Firmness value of samples ranged from 126.86 to 347.46 N, with an increase with ozone concentration. Mean fat particle size (D[4.3]) value of samples decreased with higher ozone concentration in churning water. OW reduced the oxidative stability of samples. Microbial reductions by churning with ozonated water ranged from 0.07 to 1.59 log. Microbiological analysis results showed that ozone treatment improved the microbial safety of butter samples produced from raw cream.

Gul, Volkan; Coban, Furkan
Sunflower (Helianthus annuus L) has gained importance in the world as a significant oilseed for vegetable oil. The reactions of the same sunflower genotypes to varying ecologies are different, and yield and yield characteristics may vary depending on this. In this study, we were interested in understanding the differential sensitivity of specific sunflower genotypes to different agro-ecological environments in Turkey. A 2-year (2015–2016) study was conducted on a clay-loam soil in a low and high altitude environment to (i) evaluate the genotype × location × year interaction (G×L×Y) for sunflower genotypes, (ii) predict yield components performance and identify high stable sunflower genotypes, and (iii) make genotype-specific management and high performing genotype recommendations within and across agro-ecological regions. The highest yield of seed and oil yield was obtained from the Coral (G1) genotypes, averaging 3558.5 and 1535.6 kg ha-1, respectively in Erzurum and from the 64LC108 (G4) genotypes averaging 2905.7 and 1267.4 kg ha-1, respectively in Samsun ecological conditions. As a result, the determination of the sunflower genotypes suitable for the region will provide the opportunity to obtain high-yield and high quality products because the soil, environment and climatic factors of the region in which they are grown are very useful in determining seed yield and oil content.

Hasar, Ugur Cem; Kaya, Yunus; Ozturk, Gokhan; Ertugrul, Mehmet
We propose a simple method for determination of forward and backward propagation constants of nonreciprocal uniform networks or lines with asymmetric reflections. The wave cascading matrix presentation is used to diagonalize and decompose the line in terms of impedance and amplitude/phase transitions. The proposed method uses scattering parameters of the line/network connection and the thru connection, thus eliminating errors arising from fabrication tolerance and thickness of the second line. Besides, compared with conventional methods which necessitate calibration techniques such as the thru-reflect-line, our method has the advantage that it determines propagation constants without resorting the measurement of any reciprocal reflective standard. Propagation constant measurements of a reciprocal network (different-length X-band waveguide straights) and a nonreciprocal network (microwave phase shifter) were first carried out and then compared with those measured by different methods to validate and monitor the accuracy of our method.

Purpose: Quinoline is formed by various natural compounds, such as alkaloids from the cinchona plant, which exhibit various biological activities, and is an important building material for the development of new drugs. Quinoline can be used in anti-radiation drug development but radiation interaction properties must be determined. Material and methods: In this study, six types of synthesized quinoline derivatives were used. Fast neutron removal cross-section, mean free path, half value layer and transmission number were theoretically determined by using GEometry ANd Tracking 4 and FLUktuierende KAskade simulation codes for neutron shielding. Neutron dose absorption rates were determined using the(241)Am-Be fast neutron source and the Canberra NP series portable BF(3)gas proportional neutron detector. Gamma radiation shielding parameters were determined by using WinXCom and PSY-X/PSD software. Additionally, the genotoxic potentials of the derivatives were assessed by using the Ames/Salmonellabacterial reversion assay. Results and conclusions: Neutron shielding parameters such as removal cross-section, mean free path, half value layer and transmission number were theoretically determined for fast neutrons. To determine neutron absorption capacity of quinoline derivatives, neutron absorption, experiments were conducted. In addition, gamma radiation shielding parameters were calculated such as the mean free path (MFP), mass attenuation coefficient (mu t), half value thickness layer (HVL) and effective atomic number (Zeff) in the energy range of 0.015-15 MeV. The results of the all quinoline derivatives have excellent fast neutron shielding power compared to ordinary concrete. In addition, all quinoline derivatives have been found to have the capacity to attenuate gamma radiation. Moreover, they absorb well in both types of radiation, do not cause secondary radiation, and they are genotoxically safe at the tested concentrations. This study has demonstrated that these products can be used as active ingredients for a drug to be developed against radiation.

Cucurbits are plants that have been used frequently as functional foods. This study includes the extraction, isolation, and characterisation of the mesocarp polysaccharide ofCucurbita moschata. The polysaccharide component was purified by gel filtration into three fractions (NJBTF1, NJBTF2, and NJBTF3) of different molecular weights. Characterisation includes the hydrodynamic properties, identification of monosaccharide composition, and bioactivity. Sedimentation velocity also indicated the presence of small amounts of additional discrete higher molecular weight components even after fractionation. Sedimentation equilibrium revealed respective weight average molecular weights of 90, 31, and 19 kDa, with the higher fractions (NJBTF1 and NJBTF2) indicating a tendency to self-associate. Based on the limited amount of data (combinations of 3 sets of viscosity and sedimentation data corresponding to the 3 fractions), HYDFIT indicates an extended, semi-flexible coil conformation. Of all the fractions obtained, NJBTF1 showed the highest bioactivity. All fractions contained galacturonic acid and variable amounts of neutral sugars. To probe further, the extent of glycosidic linkages in NJBTF1 was estimated using gas chromatography-mass spectrometry (GCMS), yielding a high galacturonic acid content (for pectin polysaccharide) and the presence of fructans-the first evidence of fructans (levan) in the mesocarp. Our understanding of the size and structural flexibility together with the high bioactivity suggests that the polysaccharide obtained fromC. moschatahas the potential to be developed into a therapeutic agent.

In the present work, we fabricated a series of six glasses to be utilized in the field of radiation shielding application. Glasses have been synthesized using a melt-quenching ordinary technique. In this work, we investigated the structural properties of these glasses using Raman spectroscopy. Moreover, optical properties have been studied in the present work. The radiation attenuation ability for the present samples was also investigated and measured using transmission geometry between 81 and 964.1 keV. The mass attenuation coefficient was measured and the results were validated by the WinXcom program. Also, radiation protection efficiency (RPE) was evaluated and discussed in terms of photon energy and Bi2O3 concentration. From RPE curve, we found that the fabricated glasses can be used as effective shielding materials especially for the low energies (81-383 keV). The half value layer also was calculated and the results of this parameter showed that S6 (contains 60 mol% of Bi2O3) has the higher probability of the interaction with gamma photons, leading to less number of photons transmitted this sample and thus better photon attenuator.

Background: The aim of this study was to determine hormonal responses to acute and chronic exposure to static and dynamic strength training programs using resistance bands in boxers. Material and methods: 19 male national boxers participated in the study. Boxers were instructed to perform strength exercises with resistance bands for 3 days a week for 8 weeks involving either dynamic (n=10) or static (n=9) resistance exercises. Blood samples were taken before exercise, immediately after the initial exercise session, and 8 weeks later following the last exercise session. Cortisol, growth hormone, adrenocorticotropic hormone adrenaline and noradrenaline levels were measured. Statistical analyses involved non-parametric analysis with an alpha level of .05. Results: Dynamic strength exercises were effective stimuli to growth hormone, adrenaline and noradrenaline, while static strength exercises provoked cortisol, growth hormone, adrenaline and noradrenaline responses both initially after exercise and after 8 weeks of chronic training. Neither dynamic nor static strength exercises were effective in prompting adrenocorticotropic changes after an exercise session or after 8 weeks of training. Conclusions: We showed that dynamic and static strength exercise protocols using resistance bands both could provoke acute and chronic hormonal responses in boxers similar to more traditional modes of such exercise.

Yılmaz, Hamid; Demir, Yunus
Aim of assembly line balancing is to assign the product parts to the workstations that constitute the assembly line. Worker assignment problem is a new problem variety in assembly lines that typically is met in different situations in which the workforce is not homogeneous. This problem is different from the well-known simple assembly line balancing problem from the view point of task execution times of nonhomogeneous workers. In this paper, we introduce a new mathematical formulation with objective function to minimize the cycle time for the assembly line worker assignment and balancing problem (ALWABP). GUROBI solver is used for the problem solution. The mathematical model is examined by using a standard test problem set. As a result of the experiments, it is observed that the proposed mathematical model is more effective in terms of solution quality and CPU time than the current mathematical method.

In this study, it is aimed to obtain plasma polymerized Thiophene (ppTh) thin films by Radio Frequency (RF) plasma polymerization technique and to determine optical, chemical and morphological properties of these films. ppTh thin films were fabricated at 25, 50, 75 and 100 W RF power, 15 minutes coating duration and 500 mTorr base pressure. ppTh thin films were analyzed by Scanning Electron Microscopy (SEM), FTIR and Uv-Vis spectroscopy. Functional groups of thin films were determined by FTIR spectroscopy, and it was investigated how coating parameters affect the chemical structure of these films. Optical properties such as absorbance, transmittance and optical band gap were determined by Uv-Vis spectroscopy. The optical band gaps of the ppTh thin films were determined to be 2.97 eV, 3.13 eV, 3.17 eV and 3.68 eV with increasing RF power, respectively. In addition, all thin films were highly transparent in the visible region (500 nm), and this transparency tended to increase with increasing RF power. SEM analysis showed that the thin films had nanosphere structure and the radius of these spheres was about 90 nm.

Göktaş, Bora; Tarakçı, İnci Erdoğan
Purpose – Work and family make up a large part of the lives of individuals and every individual has a role in social life as much as the number of groups he/she belongs to. It has become more important than ever for individuals to balance their work and family life so that they can fulfill all the responsibilities of their job and family roles. Especially in recent years, the fact that many women have started working and more families have double income has changed their job and family roles. The first consequence of not being able to balance work and family responsibilities is the dilemma between these two roles. The roles that people play in business and family life shape their lifestyles and also their needs and demands. Therefore, the conflict arising from the lack of stabilize between work and family tasks also affects the social lives of individuals and consequently the habits of consumption changes. As it is known, consumption in modern societies is not only aimed at meet the physiological and basic needs but also brings a lifestyle dedicated to the quest for pleasure. The Hedonic Consumption that emerges at this stage is a form of consumption that tends to act with emotions rather than sensations where it is not possible to be satisfied with desires and fantasies and to which the desire is continuous. In this study, the concept of business family conflict is handled with its reflections in modern consumption societies and the relation of this conflict with the consumption and hedonic consumption habits depending on the effect of this conflict on the roles of individuals.Design/methodology/approach – For this purpose, a survey was conducted with 412 blue and white collar workers who were actively working in factories operating in the Organized Industrial Zone of Bilecik and Bayburt Province in July-August 2019 and 390 evaluable questionnaires were obtained. In the light of the findings, it was tried to put forward the influence of work family and family work discord and hedonic consumption habits of the workers.Findings – According to the study findings, work-family conflict has no effect on social shopping, adventurous shopping and shopping to make others happy dimensions, while it has a negative effect on shopping for relaxation, shopping to get ideas and shopping for value dimensions. On the other hand, family-work conflict has a positive effect on all dimensions of hedonic consumption except the adventurous shopping dimension. The strongest effect is on shopping for relaxation dimension.Discussion – The WFC independent variable has no effect on hedonic consumption. However, the other independent variable FWC has an effect. In order to see whether the findings in the present study are supported or not, it is recommended that researchers conduct new studies using different research methods and different research areas (universe and sample).

Çorapsız, Muhammed Reşit; Kahveci, H.; Fatih Çorapsız, M.
The fluctuations in both speed and torque magnitudes during operation are among the major disadvantages of brushless DC motors. These fluctuations occur due to both the commutation of the inverter switches and the phase winding inductances. This case can lead to major problems, especially in applications which are required constant speed and constant torque. In this work, it was aimed to reduce speed fluctuations that occur in brushless DC motors. Firstly, the simulation model was created by using the dynamic equations of the brushless DC motor. Secondly, a region selective circuit was designed for use in commutation regions. Finally, the commutation signals were generated from the magnitude of the torque produced by the motor. Consequently, the proposed technique was controlled under different speed conditions and was shown that the speed fluctuations can be reduced without the difficult calculations of the commutation time. According to the results obtained, it was observed that the speed fluctuations were significantly reduced.

For this purpose, the DNA comparison of 12 plant species(Convolvulus sepium, Astragalus christianus, Taraxacum androssovii Medicago varia, Alyssum murale, Artemisiaspisigera, Falcaria vulgaris, Anchusa strigose, Glaucium leiocarpum, Salvia syriaca, Cryciata taurica Tragopogonalbinervis)collected from the areas of 10000 m (Control area) or 0-100 m away from Askale cement factory in Erzurum;was performed. 16 primers were used, and 390 bands were obtained. Important differences were observed in plant RAPDprofiles collected from 0-100 m areas when compared to their respective controls (10000 m away from the factory). Somebands in control plants got lost, and new band formations were observed. The Genomic template stability (GTS) valuedecreased significantly in plants collected from 0-100 m area as compared to the controls (%56.20). Soil samples from 0-100 m and control area were collected and examined for their heavy metal contents. According to the analysis results,Nickel, Cadmium, Zinc, Lead and Copper concentrations were found to be dramatically high in the soil collected from 0-100 m as compared to the control area. These results indicate that the high heavy metal content in the soil causes thechanges in RAPD profiles and GTS in plants. The data also indicated that RAPD and GTS assays are basic, effective andreproducible means of the genotoxicity control of environmental pollution.
