In the current study, the chemical constituents, antioxidant and antimicrobial activity of the volatile oil obtained from flowers and stems of C. speciosum growing in Türkiye were investigated. Both volatile oils were extracted through the hydrodistillation method in a Clevenger apparatus followed by the GC-MS analysis. The volatile oil yield attained from flowers and stems parts were determined as 0.62% and 0.65%, respectively. The most abundant compounds were determined in the flowers. Tricosane, octadecanal and hexadecanoic acid were identified to be the major components. Tricosane (38.28%) was defined to be the major component in flowers. 2-hydroxy benzaldehyde, tricosane and hexadecanoic acid were found to be the main compounds in the volatile oil of stems. 2-hydroxy benzaldehyde (46.49%) was found to be the main constituents in stems. According to the results antioxidant activity was attained as total antioxidant substance amount (86.77 mg AA/100 mL), total phenolic substance amount (65.64 mg GA/100 mL), total flavonoid substance amount (3.92 mg QE/100 mL), ferric (III) ion reducing antioxidant power capacity (6.88 mg FeSO4/100 mL) and free radical scavenging capacity (ABTS) (50.67 mg AA/100 mL) were obtained the highest antioxidant properties were obtained in flowers of C. speciosum. C. speciosum volatile oils had antimicrobial activity against Bacillus cereus in the flowers and had no activity against bacteria and yeast-mould in the stems.

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.

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.

Göktekin, Zekiye; Şimşek, Ahmet Bahadir
Disasters are tragic events that cause losses. The curiosity of people to feel sadness and pain motivates disaster tourism. Each disaster region has the potential for disaster tourism, which offers various benefits. This chapter covers the evaluation of the disaster tourism potential of countries with the fuzzy-TOPSIS method. The criteria affecting the disaster tourism potential as the number of dead, injured, affected, and homeless people were weighted according to the evaluations of the decision-makers. Disasters that occurred worldwide between 1980-2022 were analyzed with the criteria weights based on the countries where they occurred. Decision-makers mostly evaluated the number of deaths and homeless as more effective in affecting the desire to visit a disaster area and the attractiveness of the region. Among 90 countries, it has been determined that Sri Lanka and the Russian Federation are the two countries with the highest disaster tourism potential as to the number of losses/disasters, while Ethiopia is the country with the lowest disaster tourism potential.

Araz, Onur; Cakir, Tufan; Ozturk, Kasif Furkan
The main goal of this paper is to investigate the influence of the earthquake frequency content on the optimization of tuned mass damper (TMD) for multi-story buildings. Earthquake frequency content is divided into three groups (i.e., low, intermediate and high frequency content) according to the ratio of peak ground acceleration to the peak ground velocities. Time-domain analyses are performed to obtain the dynamic responses of 10-story and 40-story shear buildings equipped with a TMD under twelve different earthquake records. Advanced firefly algorithm is used to obtain the optimum parameters of the TMD such as the frequency ratio and the damping ratio. The optimization criterion is selected as the minimization of the maximum top story displacement of the building with TMD. The optimum parameters of TMD designed by this paper and its control performance are compared with those of other previous works available in the literature. Compared to the other methods, the optimum TMD designed by this study especially performs better in reducing the maximum top story displacements. Furthermore, it is discussed why TMD is ineffective in reducing the maximum floor accelerations of 40-story building, and then the effect of different mass ratios and objective functions in reducing the maximum responses of both buildings under critical earthquake excitation is investigated in detail. The results also show that the frequency content of earthquake ground motions has a significant effect on the optimum parameters of TMD and its control performance.

Seydi Ali Reis first mentioned the declination angle in his book titled Kitab-ı Muhit in 1554. Kitab-ı Cihannüma (1654), Füyuzat-i Mıknatisiye (1731), and Mârifetname (1757) gave the magnetic declination angle values in Anatolia. We have compiled magnetic declination data from 1500 to the present day in Anatolia and Istanbul. The plot of the magnetic declination angle was drawn for the first time using historical data between 1500 and 1947 for Istanbul. Three new magnetic declination maps for the periods of 1909–1910, 1970 and 2009 were produced for Turkey. The annual change map based on the data of 1970 and 2009 is also given for whole Turkey. The agonic line extending in NW-SE direction between Sinop and Antep divides Anatolia into two regions in 1910. The mean declination values obtained from qibla direction measurements made by the Presidency of Religious Affairs in all mosques give 3.11° E for 1970 and 4.74° E for 2009 in Turkey.
- MakaleYalnız künye2022Scopus SJRQ1A comparative study to determine seismic response of the box culvert wing wall under influence of soil-structure interaction considering different ground motions
Ozturk, Kasif Furkan; Cakir, Tufan; Araz, Onur
The present study deals with evaluation of the effects of different ground motions, backfill-structure interaction (BSI) and soil-structure interaction (SSI) on dynamic response of a box culvert wing wall. In obtaining numerical results, five different earthquake records with different frequency contents, five different backfill types and four different subsoil types are taken into account. Firstly, a finite element model (FEM) and three analytical models are proposed for analysis of the wing wall-backfill system under fixed-base case, and these fixed-base models are compared with each other through both modal analysis and displacement time-history analysis under the assumption of linear-elasticity. After validating the ability of the FEM approach, by extending the fixed-base FEM to take account of elastoplastic behavior of soil and SSI, a three dimensional (3-D) model has been described, and 3-D nonlinear analyses have been carried out in time domain. The numerical results show that the seismic response of the wing walls are affected remarkably by the SSI, BSI and frequency content of the earthquake.

Junaid, Muhammad; Abdullah, Rini Asnida; Sa’ari, Radzuan; Ali, Wahid; Islam, Amber; Sari, Mahmut
This research work aims to critically analyze the efficacy of inexpensive and rapid 2D electrical resistivity tomography (2D ERT) survey for sub-surface geological delineation of granite deposits. The research work involves six ERT profiles using the Schlumberger protocol with an inner and outer electrode spacing of 5 m and 10 m, respectively. In addition, the unmanned aerial vehicle (UAV) survey is also performed to obtain the terrain information of the studied area. At the same time, a few boreholes are drilled to validate the 2D ERT interpretations. The 2D ERT survey reveals that strong resistivity contrast enables inverted resistivity imaging to characterize the deposit such as topsoil (100-800 Ωm), fracture granite (800-2300 Ωm), and solid granite (> 2300 Ωm). The results obtained from UAV, 2DERT, and borehole survey are further processed to estimate the bedrock to topsoil ratio to assess the feasibility of the deposit. The bedrock to topsoil ratio, estimated by 2D ERT and borehole, is 3.2 and 2.2, respectively. At the same time, the combined UAV, 2D ERT, and borehole survey calculates the bedrock volume 3.2 times to topsoil. Thus the research work allows us to conclude that 2D ERT is an inexpensive, viable, and efficient technique for sub-surface geological documentation, and helps select appropriate mining methods.

Kurnaz, Muammer
Although the fire salamander, Salamandra infraimmaculata, is relatively distributed in a broad area in the Middle East, it lives in a narrow area in southeast and south Anatolia in Turkey. The habitats of the species have been downgraded day by day, and its IUCN category is listed as "NT, and the population trend is decreasing. Within the scope of this study, a model was created with the existing locality records of the species using ecological niche modeling. As a result of this model, the current and future distribution of the species were compared. The results obtained from the analyzes made within the scope of this study showed that the current probable distribution of the species coincides with the existing locality records. However, for possible climate change scenarios, the possible future distribution of the species will be thought to be negatively affected by the increase in the greenhouse gas effect, the change in the amount of carbon dioxide, and the increase of many harmful gas concentrations in the atmosphere. If all four climate scenarios proposed in this study in the future occur sequentially, the species will have to limit or change its range, and even become will be extinct in some areas. Species conservation action plans should be initiated, and local governments should take necessary measures to prevent this from happening.

Kaya, Selim; Çeli̇k, Necati; Bayram, Tuncay
As well known, High Purity Germanium (HPGe) detectors have a wide range of applications in every area where radiation detection and measurements are involved. One of the most important parameters in this respect is the determination of the full energy peak (FEP) efficiency. There are certain parameters affecting the so-called FEP efficiency. Perhaps the most important one is the thickness of dead layers of the crystal itself. In the current study, we investigated the effects of the thickness of front, lateral and back dead layer thicknesses of the detector crystal on the FEP efficiencies for the energy range 30 keV–5 MeV using EGS4 Monte Carlo simulation package. It was shown that the change in the thickness of the front dead layer has significant effect on the efficiency values for the energy interval 30–400 keV. The change in the thickness of the lateral and back dead layer was shown to have significant effects on the efficiencies for the energy intervals 2–3 MeV and 3–5 MeV, respectively. The results were checked using GEANT4 and a good agreement was observed.

Purpose: The aim of this study was to evaluate self-efficacy and health literacy of patients undergoing hemodialysis, to investigate the relationship between health literacy and self-efficacy, and to determine the factors affecting self-efficacy. Methods: The study was conducted in Eskisehir and Gumushane state hospitals affiliated to the Public Hospitals Association with the participation of 198 patients receiving hemodialysis treatment for chronic renal failure. The inclusion criteria were as follows: being ⩾18 years old, receiving hemodialysis, and agreeing to participate in the study. The study data were collected using face-to-face interview technique, and they were analyzed using descriptive statistics, correlation, and regression analysis. Results: The mean age of the patients was 59.73 ± 16.32 years. Of the patients, 46% were primary school graduates, and 63.6% reported having other chronic diseases. The mean health literacy and self-efficacy scores were found to be 79.43 ± 26.09 and 23.98 ± 7.42, respectively. The results showed that the self-efficacy scores of the patients increased as the general health literacy scores increased, with a strong linear correlation between these variables (r = 0.712; p ˂ 0.001). Patients with advanced age, low educational level, and widowed patients had lower self-efficacy and health literacy scores than others (respectively eta2 = 0.263, 0.116, 0.268, 0.141). Conclusion: High score of health literacy positively affects the self-efficacy score of hemodialysis patients.

Maden, Nafiz; Elmas, Ali
The origin and development of the Black Sea Basin (BSB) remain controversial. In this study, we determined the main tectonic features of the BSB using satellite gravity, heat flow, and seismological data. Positive gravity anomalies are observed in the arc region due to high-density material, while negative gravity anomalies are seen in the trench region owing to the mass deficiency and sediments. The trench region has a relatively low heat flow anomalies along the Black Sea coasts. The Moho depth increases from 18.11 km in the Eastern Black Sea Basin (EBSB) to 51.83 km in the Eastern Anatolia Plateau (EAP) with an average of 34.13 ± 6.15 km. The lithosphere thickness changed between 78.48 km beneath Anatolia and 120.57 km below the EBSB with an average of 99.17 ± 8.17 km. The low heat flow and Moho temperature values indicate that the lithosphere is strong and cold beneath the BSB. The numerical results, therefore, provide evidence for southward subduction of the Tethys oceanic lithosphere below the Anatolian plate during the late Mesozoic-Cenozoic. Considering all geophysical and geological data, we conclude that the Black Sea Basin represents a relict basin, rather than a back-arc basin.

We aim to investigate the effect of Single Market Programme on the spatial interaction of labour income share amongst the EU countries. Spatial panel data analysis is used for the aim of the study. The dataset is obtained from AMECO and WDI databases and covers the time period of 1960–2017. The results show that sign of spatial interaction between these countries in term of the labour income share has turned from positive to negative after the Single Market Programme. In other words, the Single Market Programme has induced to decrease the labour income share by negatively affecting the spatial interaction between these countries. In addition, we find that although the negative impacts of capital-output ratio and trade openness on the labour income share decrease, the negative impact of total factor productivity increases after the Single Market Programme. The results of robustness check also confirm our empirical findings.

This study seeks to form an end-to-end analysis of Open Innovation stages, developing a three-part consecutive multi-stage decision making model for a suitable innovation structure by linking the processes used to determine the innovation type (open, closed), the OI type (inbound, outbound, coupled), and the collaboration type (science-based, market-based). The decision-making criteria for the OI stage are determined by academic literature and finalized by Delphi technique. The criteria for relationships are determined through expert evaluation. The Fuzzy Analytic Network Process is applied in order to determine the weights and rankings. The most important criterion to consider when choosing the innovation type is open innovation awareness. For the OI type, the most important criterion is knowledge acquisition and, for collaboration, it is network building. This approach allows us to predict the potential risks or costs of the OI process and the possibility of decision errors can thus be reduced.

In order to determine the effect of working conditions on the lubricated wear behavior of Zn-40Al-2Cu-2Si alloy in the as-cast and T6 heat-treated states, its tribological properties were studied at different oil flowrates, contact pressures, and sliding speeds in comparison with SAE 660 bronze. It was observed that the friction coefficient, temperature, and wear volume of both materials decrease, but their average surface roughness increase with increasing oil flowrate. As the pressure increased, the friction coefficient and average surface roughness of the experimental materials decreased, but their temperature and wear volume increased. It was also found that the working temperature of these materials increased, but their wear volume showed a decrement and a subsequent increment with increasing sliding speed. In addition, their wear volume and average surface roughness showed opposite changes with the sliding speed. Zn-40Al-2Cu-2Si alloy in both as-cast and heat-treated conditions showed lower wear volume and friction coefficient than SAE 660 bronze. This indicates that Zn-40Al-2Cu-2Si alloy can be used to manufacture diesel engine crankshaft journal bearings.

The spread of multidrug-resistant Gram-negative (MDR) bacteria is a global public health problem, as infections caused by MDR Gram-negative bacteria are difficult to treat. New antibiotic agents need to be developed to overcome this problem, and phytochemicals show promise at this point. In this study, methanol extracts were prepared from cinnamon, thyme, nettle, white tea, rosehip, and antibacterial activity of the methanol extracts was studied against two MDR Gram-Negative bacteria (K. pneumoniae and A. baumannii) by broth microdilution method. The MICs of methanol extracts of cinnamon, rosehip, thyme, white tea for A. baumannii were found as 0.015125 g/ml, 0.07825 g/ml, 0.030625 g/ml, 0.00796875 g/ml, respectively. It was found that only cinnamon methanol extract had antibacterial activity in the used extract concentrations against K. pneumoniae and the MIC value was 0.0605 g/ml. The effects of plant methanol extract with antibacterial activity and imipenem combinations were studied in vitro using the checkerboard method. The FIC Indexes were obtained from the checkerboard results and it was observed that the combination of methanol extract and imipenem showed an antagonistic or additive/indifferent effect but not a synergistic effect. We evaluated the binding affinity of epigallocatechin 3-gallate, quercetin, cinnamaldehyde, carvacrol, and thymol phytocompounds using in silico methods, which are well known as a phytocompounds in white tea, cinnamon, thyme, nettle, and rosehip and have antibacterial activities. The results suggested that these phytocompounds should be supported with in vivo and in vitro experiments to investigate their potential for being inhibitor candidates.

A two-wheeled self-balancing robot is considered for investigating the responses of a control moment gyroscope powered by a proportional controller to prevent the robot rollover against the constant inertia forces because of accelerations of the wheels of the robot. The amplitudes of the frequency equations related to the required angular momentum of flywheels with an optimum controller gain were also found. A simulation model of the robot using computer-aided engineering software (RecurDyn) is built to verify the equations of a Lagrangian model. The results of both obtained from the Lagrangian and that from RecurDyn simulations are analyzed comparatively, in which the proportional control loop reduces the required flywheel speeds Ω of gyros and keeps the robot in a very small amplitude of a stable sinusoidal motion in the upright position.
