Sari, Ramazan; Ünal, İnan
In this study, we work on normal-metric contact pair manifolds under certain conditions related to the Ricci curvature. We obtain some results for generalized quasi-Einstein normal-metric contact pair manifolds. We prove that such manifolds are not pseudo-Ricci symmetric. Finally, we investigate Ricci solitons on normal-metric contact pair manifolds.

In recent years, demand for products produced with goat milk has been increasing. On the other hand, compared to cow's milk, component and flavour differences in goat milk can cause significant differences in the properties of products produced with goat's milk and affect the acceptability of the product. In this study, it was aimed to compare the antioxidant capacity, rheological and sensory properties of kefir produced with goat milk with those properties of kefir produced of cow milk. In this context, cow milk, goat milk and 1: 1 ratio of cow and goat milk kefir were produced, physico-chemical, rheological and sensory analyses were performed. It was determined that the rheological properties of all kefir samples exhibit pseudoplastic behaviour and are compatible with the power-law model. The apparent viscosity of the kefir produced by the goat milk was lower than cow milk kefir. It was determined that the total antioxidant capacity of goat milk kefir was higher than cow's milk kefir and a and b values were lower in colour. On the other hand, in goat milk kefir, panellists perceived lower consistency and kefir flavour, also its overall acceptability score was lower. The addition of 50% cow's milk to goat's milk influenced the condition of goat's milk. The sensory properties of the mixture milk kefir were similar to the sensory properties of the cow's milk kefir. Although the mixture kefir positive results, it has been concluded that further studies are needed to obtain better consistency and flavour in kefir production from goat milk.

Gülmez, Nihan
Sustainable waste management is becoming more and more important in the construction industry due to increasing waste costs as well as environmental effects. As a result of increasing level of wastes and environmental damage, the use of these wastes has become the focus for beneficial construction activities and sustainable industrial applications. This study presents experimental results on the effect of industrial wastes on the performance of cementitious mixtures. The scope of this study, therefore, was to assess the effect of waste aluminium on physical and mechanical properties of cement based mixtures prepared in different compositions. Consistency, bulk density, porosity, absorption, flexural and compressive strength tests were carried out on mixtures produced by using waste aluminium aggregates in different percentages instead of fine aggregate. Results showed that mixtures prepared with 4% aluminium aggregates had the highest water absorption and porosity. With the addition of %1 lathe waste, it was observed that the flexural behavior of mortar was maximum and the optimum percentage for flexural strength was noted. In addition, when mixtures produced with the same percentage of aluminium were compared, the amount of binder played a significant role on both compressive and flexural strength. Results have shown that to incorporate aluminium into mixtures can be a suitable solution for recycling in industrial applications.

Köseoğlu, Murat; Günay, Mıhrıban
In this study, one of deep learning methods, which has been very popular in recent years, is employed for the detection and classification of circuit components in hand-drawn circuit images. Each circuit component located in different positions on the scanned images of hand-drawn circuits, which are frequently used in electrical and electronics engineering, is considered as a separate object. In order to detect the components on the circuit image, Faster Region Based Convolutional Neural Network (R-CNN) method is used instead of conventional methods. With the Faster R-CNN method, which has been developed in recent years to detect and classify objects, preprocessing on image data is minimized, and the feature extraction phase is done automatically. In the study, it is aimed to detect and classify four different circuit components in the scanned images of hand-drawn circuits with high accuracy by using the Python programming language on the Google Colab platform. The circuit components to be detected on the hand-drawn circuits are specified as resistor, inductor, capacitor, and voltage source. For the training of the model used, a data set was created by collecting 800 circuit images consisting of hand drawings of different people. For the detection of the components, the pretrained Faster R-CNN Inception V2 model was used after fine tuning and arrangements depending on the process requirements. The model was trained in 50000 epochs, and the success of the trained model has been tested on the circuits drawn in different styles on the paper. The trained model was able to detect circuit components quickly and with a high rate of performance. In addition, the loss graphics of the model were examined. The proposed method shows its efficiency by quickly detecting each of the 4 different circuit components on the image and classifying them with high performance.

In this study, DPPH and fatty acid contents were investigated of some taxa belonging to Neckeraceae (Alleniella complanata, Alleniella besseri, Exsertotheca crispa) and Hypnaceae (Hypnum cupressiforme, Hypnum resupinatum, Hypnum andoi) family collected from Kamilet Valley (Artvin-Arhavi) in 2017. DPPH free radical scavenging activity was determined according to the method developed by Brand-Williams et al. The fatty acids in extracts were analyzed via gas chromatography after transforming them into methyl esters. According to the obtained results, it was determined that the DPPH scavenging effects of taxa from Hypnaceae family were significantly higher than those of taxa from Neckeraceae family, and that the free radical scavenging effects of taxa from Hypnaceae family varied depending on the amount of extract. The saturated fatty acids content of the Neckeraceae and the unsaturated fatty acids of the Hypnaceae were found to be richer (p<0.001). The high DPPH activity in our study, especially in Hypnum species, suggested that Hypnum species were richer in terms of phenolic content. These compounds can be used in the pharmaceutical, cosmetic and food sectors, if both of these species are phenolic and fatty acid content can be obtained as pure.

Fish cells have been accepted as an alternative to in vivo assay for inflammatory effects of therapeutic experimental systems. To reveal the anti-inflammatory effects of Inula viscosa (IV) fish cell line RTG-2, derived from the gonadal tissue of rainbow trout, was infected with lipopolysaccharide (LPS). Effective concentrations for different concentrations of LPS (1, 5, 10, 20 mu M) and IN (1, 5, 10, 20 mu g ml(-1)) were determined. While the 20 mu M concentration of LPS, which was effectively selected from preliminary tests, caused 27% cell loss, the effective 1 mu g ml-1 concentration of IN caused 1.1% proliferation in the cells when compared to the control group. All pro-inflammatory parameters investigated in LPS-induced RTG-2 cells showed up-regulation, with the highest increase in TNF-alpha gene expression level (11.3 fold changes). Down-regulation was determined in the IN together with LPS administered group and IL-1 beta had the highest effect with 96%. IL-6 protein level decreased by LPS at a rate of 4% and IN together with LPS increased by 9%. The IN exhibited significant efficacy against inflammation caused by LPS. However, further studies are needed to determine pharmacological activity of I. viscosa in details.

Blair et al. [7] introduced the notion of bicontact manifold in the context of Hermitian geometry. Bande and Hadjar [1] studied on this notion under the name of contact pairs. These type of structures have important properties and their geometry is some different from classical contact structures. In this paper, we study on some semi-symmetry properties of the normal contact pair manifolds. We prove that a Ricci semi-symmetric (or concircularly Ricci semi-symmetric) normal metric contact pair manifold is a generalized quasi-Einstein manifold. Also, we classify normal metric contact pair manifolds as a generalized quasi-Einstein manifold with certain semi-symmetry conditions L (X, Z).R = 0, R(X, Z).L = 0 and L (X, Z).L = 0 for the concircular curvature tensor L, the Riemannian curvature tensor R, and an arbitrary vector field X.

Korkmaz, Meral
The greatest need of the modern world is energy. From production to consumption, energy has become essential in all areas. As fossil-derived energy production systems cause global warming and climate change, interest in renewable energy sources is increasing. Despite the pandemic, solar production has shown promising growth throughout the world. Turkey has been encouraging investments in renewable energy sources, especially solar energy, for the last 10 years. Feasibility studies before the installation of solar power plants are crucial for investors. As a result of feasibility studies, the cost of the investment and the depreciation period can be calculated. In this study, feasibility studies of the 474 kWp power plant in Samsun province were carried out with PVsyst program. Significant differences were found between the software results and the actual results of the solar plant built in Samsun province. Production losses between actual data and numerical data are thought to be related to meteorological data. There are numerous studies in the literature about PV software. However. current studies have not examined the effect of meteorological data of the region on the difference in production between PV software results and solar power plant production values. In this study, the Sen method was used to determine the precipitation trend by taking meteorological data from Samsun province. With this method, rainfall in Samsun province was seen to be on an upward trajectory. For this reason, in regions where there is a lot of precipitation; feasibility studies of solar power plants are falling by approximately 9 percent.

Sançar, Taylan
Collision of the Arabian and Eurasian plates has resulted in uplift of the Turkish-Iranian Plateau, where debate continues over how post-collisional convergence is being converted to strain. The internal deformation models of the plateau have taken into account the distribution of deformation in the NW-trending Bitlis-Zagros Mountain Range (BZMR), the southern boundary of the collision. The western end of the BZMR is marked by contrasting topographic relief resulting from the coupling of tectonic and erosional processes. This region providing an excellent record for undertaking quantitative analysis which can improve our understanding of its tectonic evolution. Mountain front analyses reveal that each fault segment located in front of the western BZMR falls within the limits of Class-1 that corresponds to an uplift rate of >0.5 mm yr(-1). Hypsometric and basin asymmetry analysis were analyzed for 93 drainage basins, indicating that weakly to moderately eroded basins can be moderately to strongly asymmetric but show no uniform tilting direction. Channel concavity, integral and knickpoint analyses suggest that, apart from the thrust fault that represents the margin of the collision zone, there is no pronounced single geological constraint that causes differential tectonic uplift and furthermore implies that the effect is distributed across multiple different structures. The findings of this study suggest that continuous lower rate horizontal displacement has occurred in this region since the onset of collision, but also indicates that the western end of the BZMR represents a zone of higher convergence, in which shortening is being converted to the vertical plane strain.

The Vitis vinifera L. grape species is a fruit that is the most prevalently grown in the whole world and has economic significance. It is known that, due to its climate conditions, Turkey has rich resources in terms of Vitis vinifera L. With this study, we aimed to determine the phenolic, vitamin and fatty acid contents of the Okuzgozu and Bogazkere varieties of Vitis vinifera L. and see the effects of these contents on antioxidant activity. Fatty acids in the lipid extract were analyzed by gas chromatography after conversion into methyl esters. For flavonoid and vitamin analyses, a high-performance liquid chromatography device (HPLC-UV. Shimadzu) was used. Antioxidant activity was determined by Radical Scavenging Activity (DPPH) and Lipid Peroxidation (MDA) experiments, As a result of the study, some saturated and unsaturated fatty acid, phenolic compound and vitamin contents of the two varieties were obtained. It was observed that the amounts of unsaturated fatty acids, whose effects on antioxidant activity are known, in the Okuzgozu variety were significantly higher than those in the Bogazkere variety. The results on phenolic and vitamin compounds revealed higher amounts in the Okuzgozu variety in comparison to Bogazkere as in the case of fatty acids. The finding that these contents and antioxidant activity were in proportion suggested that the antioxidant effect of the Okuzgozu variety is higher. If the substances that provide this effect are correctly isolated from the plant, they may be used beneficially in both the food and pharmaceutical sectors.

This study aims to determine the effect of coaches' perception of executive support on job satisfaction. A relational screening model was used in the study for this purpose. Disproportionate sampling was used within the scope of the study, and 516 coaches working in various provinces of Turkey composed a sample of the study. The scale of executive support developed by Karasek et.al (1985) and adapted by Kula (2011) and the scale of job satisfaction made by Bilir and Keser (2019) was used in the collection of data. Pearson Correlation analysis was used to reveal the relationship between scores from scales, Linear Regression analysis was used to determine whether the scores obtained affected each other. Error level in the study was taken as p<0.01. It has been determined that there is a positive and meaningful relationship between the executive support levels of coaches in Turkey and the levels of job satisfaction. It can be said that as the level of executive support increases, the levels of job satisfaction increase. According to linear regression analysis, it was determined that the level of executive support positively affected the job satisfaction levels of coaches. It was observed that the executives' support scores of coaches in Turkey were higher than average with an average of 3.53 and job satisfaction scores were high with an average of 4.08 in our study.

Yazici, Muge; Zabci, Cengiz; Natal'in, Boris A.; Sançar, Taylan; Akyuz, H. Serdar
The Ovacik Fault (OF) is one of the internal structures of the Anatolian Block, located close to its eastern boundary. Although it shows a very clear surface trace, there are no instrumentally recorded surface rupturing earthquakes on this fault. This study concludes results of the first palaeoseismological trench study on the OF with the evidence for three surface rupturing earthquakes for the last 6 kyr. Structural, stratigraphical and geochronological constraints show that the oldest event happened between 4700 and 3022 BCE, whereas the penultimate event was between 2262 and 1643 BCE. The youngest event happened after 56 BCE, which we could only delimit from below because of the absence of any dateable material from the upper layers of the relevant horizons. The derived mean interevent time of these three palaeoevents is 2400 +/- 765 years. We could not correlate any of these palaeoevents with historical earthquakes due to the absence of records in catalogues for the region of interest. Moreover, we used cumulative offsets of the major drainages to calculate the long-term slip rate of 2.7 mm/year since the Pliocene, which exceeds slip rates of other internal faults of Anatolia almost by the factor of two. Our results do not only show significant deformation for the internal parts of Anatolia but also point out a seismic potential of the OF.

Background: It is known that people's relations with nature can be greatly influential in all periods of their lives and especially in their future, which has increased their interest in concepts such as environment, nature, natural life, ecology, ecosystem as a result of the increase in natural awareness in humans. Aim: Based on these ideas, our research aims to measure the attitudes of cycling athletes in Elazig province towards ecorecreation.. Methods: A total of 178 athletes from 242 cycling athletes, including cycling sports clubs, associations, and individual athletes in Elazig province, participated voluntarily. It consists of 31 substances and 6 sub-dimensions developed by Ayyildiz and the 'Personal Information Form' prepared by the researchers as a data collection tool. Attitude Scale Towards Ecorecreation(ASTE), which was created in a 5-point Likert type format, was used. Spss 22.00 package program was used for the analysis of the data and the level of significance was determined as p<0.05. In the study, t-test analysis was applied to determine the significance of the differences between two groups and ANOVA was applied to determine the significance between more than two groups. Pearson correlation analysis was used to determine the direction and severity of the relationship between variables. Results: As a result of the research, there was a semantic difference in the individual and environmental sensitivities of licensed cycling athletes. A significant difference was observed in the Attitudes and Behavior towards Ecorecreation sub-dimensions of the athletes who are interested in another nature sport. Conclusion: The increase in positive behaviors towards nature has clearly become clear that it is directly related to being in nature. Accordingly, researchers believe and draw attention to the fact that in order to increase the positive effect on nature, it is necessary to be intertwined with nature and to adopt it.
