    An Investigation of the Antiproliferative Effect of Rhododendron luteum Extract on Cervical Cancer (HeLa) Cells via Nrf2 Signaling Pathway

    Turan, Ibrahim; Demir, Selim; Yaman, Serap Ozer; Canbolat, Deniz; Mentese, Ahmet; Aliyazicioglu, Yuksel

    The aim of the present study was to investigate the role of Rhododendron luteum extract (RLE) in the induction of Nrf2‑related oxidative stress and endoplasmic reticulum (ER) stress in human cervical cancer (HeLa) cells. The antiproliferative effect of RLE on HeLa and fibroblast cells was determined using the MTT assay. The effects of RLE on the cell cycle, apoptosis, and production of reactive oxygen species (ROS) in HeLa cells were evaluated using fluorescent probes. The mRNA expression levels of Nrf2 [and its targets glutamate-cysteine ligase catalytic subunit (GCLC), and glucose-6-phosphate dehydrogenase (G6PD)], and C/EBP homologous protein (CHOP, an ER stress marker were determined using reverse transcription‑quantitative polymerase chain reaction (RT-PCR). The results demonstrated that RLE exhibited a selective cytotoxic effect (2.9-fold) on HeLa cells compared to fibroblast cells. RLE arrested the cell cycle at the S phase, and induced apoptosis, ER stress, and ROS formation. In addition, RLE significantly suppressed the expression levels of Nrf2, GCLC and G6PD (0.65, 0.69, and 0.54-fold, respectively) and increased the expression of CHOP (4.48-fold) in HeLa cells at 72 h of treatment (p < 0.05). These results show that the antiproliferative effect of RLE occurs through the Nrf2 and ER stress pathways, and the results should now be supported by further in vivo studies.

    The relationship between banks’ credit quality, credit growth and social capital: evidence from Turkish banking sector

    Pilatin, Abdulmuttalip; Ayaydin, Hasan

    The aim of this study is to empirically examine the relationship between credit growth, credit quality and social capital of all commercial banks operating in Turkey for a period of twelve years between 2007 and 2018 on the basis of 81 provinces. In order to measure social capital on a provincial basis, the independent variable SC1 was obtained by applying principal component analysis to the variables consisting of 2 network and 2 norm variables. In addition, province-based organ donation rate was used as an alternative social capital variable. Changes in Total Loans (ΔTL), Changes in Real Estate Loans (ΔREL), Changes in Commercial and Industrial Loans (ΔCIL), Changes in Construction Loans (ΔCL), Changes in Non-Performing Loans (ΔNPL), Ratio of Non-Performing Loans to Total Loans (NPL/TL) and Ratio of Non-Performing Loans to Total Assets (NPL/TA) were determined as the dependent variable. The relationship between the level of social capital (SC1) and seven dependent variables on a provincial basis in Turkey was analyzed and measured using panel data techniques. The results of the analysis show that the relationship between the social capital level of the provinces, credit growth and non-performing loans are negative and significant. The results of the study show that the level of social capital is important and decisive in terms of credit growth and credit risk of banks.

    Performance evaluation of privatized ports by entropy based TOPSIS and ARAS approach

    Gök-Kısa, A. Cansu; Çeli̇k, Pelin; Peker, İskender

    Purpose: Ports are the key elements of maritime transportation, which is crucial for world trade. Approximately 180 port facilities are located in Turkey. After 2007, 5 of the ports, which are formerly owned by Turkish Republic Railways Administration (TRRA), are privatized. The aim of the study is to evaluate the performance of these privatized ports by multi-criteria decision-making (MCDM) approach. Design/methodology/approach: The application process is performed by a MCDM model. This model includes both criteria (dry bulk, liquid bulk, general cargo, container, RO-RO capacity, total port area, total berth, total berths length and depth) and alternatives (Mersin, Samsun, Bandirma, Iskenderun and Derince Ports). It determines the weights of the criteria by entropy and ranks the alternatives by ARAS and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) methods. Findings: The results of entropy, ARAS and TOPSIS methods are compared. According to these results, “container” is the most important criteria while Mersin port has the best performance. Originality/value: In the literature, most of the studies about this subject were analyzed by data envelopment analysis (DEA) and there are no studies had been taken into consideration ports that are owned by TRRA, in Turkey. Moreover, few of these studies used integrated MCDM models, and this is the first study that integrates entropy, ARAS and TOPSIS methods in this field.

    Detection of damaged buildings after an earthquake with convolutional neural networks in conjunction with image segmentation

    Ünlü, Ramazan; Kiriş, Recep

    Detecting damaged buildings after an earthquake as quickly as possible is important for emergency teams to reach these buildings and save the lives of many people. Today, damaged buildings after the earthquake are carried out by the survivors contacting the authorities or using some air vehicles such as helicopters. In this study, AI-based systems were tested to detect damaged or destroyed buildings by integrating into street camera systems after unexpected disasters. For this purpose, we have used VGG-16, VGG-19, and NASNet convolutional neural network models which are often used for image recognition problems in the literature to detect damaged buildings. In order to effectively implement these models, we have first segmented all the images with the K-means clustering algorithm. Thereafter, for the first phase of this study, segmented images labeled “damaged buildings” and “normal” were classified and the VGG-19 model was the most successful model with a 90% accuracy in the test set. Besides, as the second phase of the study, we have created a multiclass classification problem by labeling segmented images as “damaged buildings,” “less damaged buildings,” and “normal.” The same three architectures are used to achieve the most accurate classification results on the test set. VGG-19 and VGG-16, and NASNet have achieved considerable success in the test set with about 70%, 67%, and 62% accuracy, respectively.

    The effect of tourism and legalization policies on summer pasture in Turkey

    Döner, Fatih

    In Turkey, according to Pasture Law, land allocated for farmers to spend the summer with their animals, graze their animals and benefit from grass is defined as “summer pasture (yaylak in Turkish).” Summer pasture is of national importance for its biodiversity, landscape, cultural heritage and transhumance. However, especially after 1990s, the summer pasture areas have been extensively used in tourism activities in Turkey. By changing land use, the increasing tourism activities combined with legal uncertainties and the legalization policies have caused summer pasture areas transferred into built-up areas. The effect of the tourism and legalization policies on the land use changes in summer pasture areas was evaluated in this study. It was determined that Turkey's tourism and legalization policies have adverse effect on sustainable use of summer pasture areas. These policies aimed at economic development and solving property problems of rural areas caused new legal problems and expansion of built-up areas. A better land use policy and an effective control mechanism are necessary for the sustainable use of summer pasture areas.

    Hidden Diversity in a Narrow Valley: Description of New Endemic Palearctic Rock Lizard Darevskia (Squamata: Lacertidae) Species from Northeastern Turkey

    Kurnaz, Muammer; Şahin, Mehmet Kürşat; Eroğlu, Ali İhsan

    Darevskia is a particularly species-rich radiation of Palearctic rock lizards from the Caucasus region. Thanks to intense systematic and taxonomic research, the knowledge of species-level diversity within this genus has increased over the last quarter century. Here, we described a new species, Darevskia salihae sp. nov. from northeastern Turkey. The new taxon is differentiated from other nearby taxon by the low number of dorsal scales in the middle of the body, the shorter body length, and the absence of blue dots both on the lateral region above the forelimbs and on the margin of the ventral plates. In addition to their morphological differences, the new taxon is phylogenetically different from close groups. It is located in a separate subclade from the rudis-valentini-portschinskii subclade. This distinction is supported by both a high bootstrap value (100) and a high posterior probability value (1.00). These two subclades are separated from each other by a genetic distance of almost 4%. This separation is supported not only genetically and morphologically, but also geographically. Since the habitat of the new taxon is limited to a high mountain and a narrow valley, it does not provide an opportunity for a different Darevskia species to shelter because it creates geographical isolation. However, Darevskia parvula that live closest to the habitat of the new taxon live only at the habitat boundaries and do not enter areas where the new taxon is found. Therefore, it might be possible that while it was separated from the rudis-valentini-portschinskii group during the evolutionary transformation, it remained as a refuge and relict in a narrow area as a result of the collapse of the valleys and the partial uplift of the Kaçkar Mountains.

    Türkmen, Osman Oǧulcan; Kavakli, Mehmet; Ak, Mehmet

    Objective: Social media usage is increasing gradually and the websites that enable social interaction may influence people's loneliness and depression levels. The aim of the present research was to examine the multiple mediating roles of self-esteem and happiness in the relationship between loneliness and depression. Method: The study sample was composed of 409 Facebook and Instagram users. Data were collected by using personal information form, Beck Depression Inventory, Oxford Happiness Scale-Short Form, Rosenberg Self-Esteem Scale and UCLA Loneliness Scale. Correlation analysis was carried out to determine the relationship between variables. Multiple mediation analysis was conducted to determine the mediating roles of self-esteem and happiness in the relationship between loneliness and depression. Results: The results suggest that self-esteem and happiness, indeed, have mediating roles in the relationship between loneliness and depression, and multiple mediation models were found to be statistically significant. The frequency of accessing Instagram was positively associated with depression and loneliness. Facebook users had higher self-esteem levels compared to Instagram users. Discussion: In conclusion, the relationship between loneliness and depression was found to be significantly mediated by self-esteem and happiness. Increased frequency of access to Instagram every day was found to increases the level of depression and loneliness. Additionally, Instagram users were found to have lower self-esteem compared to Facebook users.

    Resilient active seismic response control of structural systems

    Çetin, Gökhan; Fadali, Mohammed S; Pekcan, Gökhan

    This paper proposes a dissipative resilient observer and controller (DROC) design for a network controlled system (NCS) that handles faults, implementation errors, or cyberattacks that can be modeled as bounded controller or observer gain perturbations. It presents linear matrix inequality (LMI) conditions for the robust stability of the system in the presence of bounded perturbations in the observer and controller. Furthermore, a new LMI-based time-delay control (TDC) algorithm that mitigates the effects of perturbations due to time-delays in the NCS is introduced. The robust methodology is applied to active control of a scaled model of a structural system equipped with an active mass driver system. The results demonstrate that the proposed methodology is robust and ensures stable system response due to various types of earthquake base excitations.

    Objective: (a) To investigate the presence of sacroiliac joint dysfunction in asymptomatic individuals and (b) to compare lower limb muscle shortness, flexibility of hamstring and erector spinae muscles, and hypermobility between subjects with and without asymptomatic sacroiliac joint dysfunction. Material and Methods: A total of 54 healthy young adults subjects were included in the study. The subjects were assessed with the sacroiliac joint diagnostic procedure. The seated flexion test, the standing flexion test, the Gillet test, and bilateral bony landmark examination were performed by an expert investigator. According to the positivity of at least 3 of these tests, the subjects were divided into 2 groups, the asymptomatic sacroiliac joint dysfunction group and the control group. The shortness of tensor fasciae latae and iliopsoas muscles was evaluated with the modified Ober test and the modified Thomas test. The straight leg raise test and fingertip-to-floor test were carried out for hamstring and erector spinae muscles flexibility, while hypermobility was assessed according to the Beighton criteria. Results: The asymptomatic sacroiliac joint dysfunction was diagnosed in 38% of healthy adults. There was no statistical difference in the shortness of tensor fasciae latae and iliopsoas muscles between the asymptomatic sacroiliac joint dysfunction group and the control group (P > 0.05). Similarly, there was no difference between the groups in terms of the hamstring and erector spinae muscles flexibility, and the Beighton scores (P > 0.05). Conclusion: This study emphasized that asymptomatic sacroiliac joint dysfunction might be seen in healthy young adults without the difference in shortness and flexibility in the lower extremity and hypermobility.

    Investigation of biodegradability of doped composite oxide coated AZ91 alloy in blood plasma; [Katkili oksit kaplamasi büyütülen AZ91 alaşiminin kan plazmasi içerisindeki biyoçözünürlüǧünün incelenmesi]

    Şüküroǧlu, Ebru Emine; Çelik, Ayşenur

    Magnesium alloys; It is widely used in metallic biomaterials with its low toxic effect and biodegradability. Although these alloys help the formation of new tissues in the body, they provide great advantages over other metallic biomaterials due to their ability to dissolve from the body after the area of use has healed. However, due to their low corrosion resistance, they cause it to dissolve in the body before the treatment process is completed. This is the major disadvantage that limits the use of magnesium alloys. Various surface modification methods are applied to magnesium alloys in order to eliminate this disadvantage. Micro Arc Oxidation (MAO) method, which can provide a coating resistant to wear and corrosion, is one of the surface modification methods applied to improve the surface properties of magnesium alloys. In this study; Composite oxide coatings with Ag nanoparticle and Hydroxyapatite were grown by MAO method. Morphological properties of the coatings were determined by Scanning electron microscope and X-Ray Diffraction instruments. The antibacterial properties of Ag nanoparticle and HA doped composite oxide layer which were grown by MAO method and the biodegradability of the coated/uncoated materials in the blood plasma were investigated. As a result of the experiments, the development of bacterial activity in the sample coated by MAO was prevented by adding Ag nanoparticle and Hydroxyapatite to the electrolite solution. In addition, the biodegradation rate has been reduced by surface treatment on AZ91 Mg Alloy. As a result of the soaking test in blood plasma, it was determined that AZ91 Mg alloy protects itself against dissolution with a rate of approximately 89%.

    Scrutinizing blockchain applicability in sustainable supply chains through an integrated fuzzy multi-criteria decision making framework

    Erol, Ismail; Ar, Ilker Murat; Peker, Iskender

    Sustainability has become increasingly important over the last three decades and has proven to be a key enabler for constructing resilient supply chains. Customers who want their products to be authenticated for sustainability put pressure on Original Equipment Manufacturers and suppliers to become more sustainable on a global scale. Moreover, social sustainability issues have become more challenging to address, and a growing number of stakeholders put emphasis on societal concerns. To this end, decision-makers are becoming increasingly interested in applying disruptive technologies to address societal, environmental, and economic concerns and accomplish sustainability goals. Researchers argue that disruptive technologies such as blockchain may be implemented to assist supply chains towards building sustainability. However, our literature analysis concluded that existing research has not quantitatively examined the critical functions of sustainable supply chain (SSC) for blockchain applicability using a decision framework. Therefore, this research, through Fuzzy SWARA-COPRAS-EDAS and COPELAND-based framework, is aimed at investigating the most feasible functions of a SSC for potential blockchain implementations. Using this framework, the critical functions of a SSC were ranked against the benefits of blockchain. The findings of this study implied that while sourcing, delivery, transformation and product recovery proved to be the most appropriate functions of SSCs for blockchain applications, customers and product use was the least feasible one. This study aids decision-makers in gaining a more thorough understanding of where in a SSC blockchain may create additional value.

    Consumers’ willingness to pay for traditional products with geographical indication: a case study on pestil from Gümüşhane, Turkey

    Dogan, Nilgun; Adanacioglu, Hakan

    The main purpose of this study is to analyze the willingness to pay (WTP) geographical indications (GI)-labelled pestil as a traditional product. Considering the data obtained from a survey conducted with 166 households in Gümüşhane, Turkey were used. Contingent valuation method was taken to determine WTP for GI-labelled pestil (dried fruit pulp). In order to find WTP price amounts Tobit model was used. Tobit model showed that individuals who were in the upper age group, have a high frequency of purchasing pestil, have a high level of knowledge about GI-labelled products, and consume GI-labelled products want to consume more. The average amount that consumers will be willing to pay for 1 kg of price bids ranging from 60-100 TRY has been determined as 68.74 TRY. While establishing a target market, those who are in the upper age group, have a high frequency of purchasing pestil, have a high level of knowledge and consume GI-labelled products should be taken into consideration. Since individuals with a high level of knowledge regarding GI-labelled products are willing to pay a higher amount of extra payment, it is recommended that marketers carry out promotional activities that will increase communute awareness for GI-labelled products.

    Angular Momentum Control for Preventing Rollover of a Heavy Vehicle

    Ünker, Faruk

    In this article, gyroscopes and flywheels are used to prevent the rollover of a vehicle due to external forces. The rollover preventing performance of the flywheels for a heavy trailer (an inverted pendulum problem) is investigated at a high road bank angle risk. Two control moment gyroscopes (CMG) and a reaction wheel are controlled by proportional torques to keep the vehicle in a stable motion in the vertical position. The reaction wheel was used only to eliminate the dissipation energy of damper. By using the energy stored in the flywheels of gyroscopes, the sprung mass of a vehicle can make a stable oscillating motion of small amplitude, standing upright without tipping over. The optimum flywheel speed was derived from the frequency equations with the appropriate controller gain. Most importantly, the required angular momentum to keep the vehicle upright without tipping over depends on the amplitude of the gimbal oscillation and the frequency. It has also been observed that Matlab simulations of Lagrangian equations and simulations modeled in RecurDyn software are in perfect harmony.

    Microwave decontamination process for hummus: A computational study with experimental validation

    Son, Ezgi; Coskun, Eda; Ozturk, Samet; Bulduk, Kubra; Akpinar, Merve; Mert, Behic; Erdogdu, Ferruh

    There has been an increasing demand for healthy snacks, and hummus is preferred as a plant-based product its rich protein content. Its increased consumption, on the other hand, has raised food safety issues with linkages to Listeria outbreak and a recent Salmonella related recall. These were observed in ready-to-eat hummus and indicated the requirement of further processing. Conventional thermal processes might require longer times with negative impact on the quality due to the high viscosity of hummus with its solid-like rheology. For an efficient process design, microwave (MW) processing might be considered with its volumetric heating feature. Therefore, the objective of this study was to present MW application for a decontamination process for hummus. For this purpose, a computational model was developed to determine the temperature change during the process. This model was validated using the experimentally obtained temperature data from samples processed in polystyrene petri dishes (60 g – 8.5 cm in diameter and 1.2 cm in height) in a lab-scale MW system. Color changes were determined, and changes in its viscosity were used to understand the variation in the rheological attributes. Hummus samples were also inoculated with Salmonella cocktail to ≈7–8 log10 CFU/g prior to the MW process, and 70 W MW processing for 5 min (to average temperature of 95.3 °C) resulted in >4 log cycle reduction. Changes in color and rheological attributes were not significant with rather limited mass losses, and these indicated the possible MW processing for hummus decontamination with the need of designing an industrial scale processing.

    Characterization of the Welding Zone of Automotive Sheets of Different Thickness (DP600 and DP800) Joined by Resistance Spot Welding

    Aydin, Kemal; Hidiroglu, Mehtap; Kahraman, Nizamettin

    Automotive industry in recent years, has gained great importance. In line with this, DP600 and DP800 dual-phase steels and the electrical resistance spot welding method were used in the study. During the experimental trials, different welding currents (6, 7, and 8 kA) were selected and all other welding parameters were kept constant. The effects of the welding parameters on microstructure, hardness, tensile-shear, and cross-tensile strength were analyzed. In the phase measurements, 27.06–29.97% martensite and 70.73–73.85% ferrite phases were found. When the hardness values in the HAZ regions were examined, it was seen that the highest hardness values were 356 ± 5 HV in the DP600 and 451 ± 5 HV in the DP800 with a current intensity of 6 kA. Consequently, it was determined that tensile-shear and cross-tensile strengths had increased in parallel with the increase in the welding current and the highest values were determined as 8 kA–15.91 kN in tensile shear and 8 kA–4.91 kN in cross-tensile strength.

    Analyzing and Predicting Spatiotemporal Urban Sprawl in Eskişehir Using Remote Sensing Data

    Küçük Matcı, Dilek; Çömert, Resul; Avdan, Uğur

    Urban areas of major cities in developing countries are expanding rapidly due to rapid population growth and industrialization. Determining the reasons for rapid urbanization and the amount of urban area that will be needed in the future is important for the planned growth of these cities. In this study, the LU/LC change of Eskisehir city center that has a rapid rate of urbanization and industrialization in Turkey between 1984 and 2020 was determined. Then, the area needed for urban and industrial areas in 2030 was investigated using the Cullullar Automata–Markov Chain (CA–MC) hybrid model simulation. Each year's LU/LC map was produced with over 80% kappa accuracies performing the pixel-based Random Forest (RF) algorithm for change analysis. In the change analysis made between 1984 and 2020, it was determined that there was a change of 117% in the urban area and 977% in the industrial area. The prediction was made for the validation of the CA–MC model from the period 2000–2010 to 2020. When compared with the 2020 LU/LC map, the model success was obtained as 0.84, 0.87, and 0.87 in the Kstandard, Klocation, and Kno Kappa metrics, respectively. By using the 2010–2020 periods in the estimation of 2030, it has been observed that the urban and industrial area will increase by 22.95%; therefore, there will be decreases in agriculture and other natural areas as in previous years.
