- MakaleAçık Erişim2024Integration of a CNN-based model and ensemble learning for detecting post-earthquake road cracks with deep features
Reis, Hatice Catal; Turk, Veysel; Karacur, Soner; Kurt, Ahmet Melih
A safe and healthy infrastructure is essential for humanity. Maintenance and repair of roads, which are of great importance, especially in transportation, is essential. Roads can sometimes be damaged due to natural disasters or human factors. In this study, roads damaged as a result of the natural disaster and the 6 February 2023 Gaziantep-Kahramanmaras earthquakes, which had devastating/fatal consequences, were studied. In recent years, the use of machine learning methods in the automatic detection process of road cracks has become widespread. Here, deep learning architectures generally based on multilayer convolutional neural networks have become a popular solution, mainly thanks to their high discrimination power in visual data. In this study, it was aimed to automatically detect cracks on the roads in Gaziantep (Nurdagi) and Adiyaman provinces after the earthquake. The data set used in the experimental process consists of two categories: uncracked and cracked, and was collected by the researchers. ResNet152 deep learning architecture, traditional machine learning algorithms, and an ensemble learning (EL) model were used to classify cracks. Among the machine learning algorithms used in the experiments are support vector machine (SVM), K-nearest neighbors, Adaptive Boosting, and Naive Bayes. In the experimental process, ResNet152 architecture was used for feature extraction, and classification was carried out with machine learning algorithms. In addition, the EL method has been used to improve the success of machine learning algorithms. According to experimental results, the SVM algorithm and EL method gave the most successful results with 98.68% accuracy values. The proposed method can benefit experts in the automatic classification of road cracks. The study can contribute to activating rapid coordination and transportation networks in natural disasters that cause fatal and destructive causes, such as earthquakes.

Duran, Celal; Ozdes, Duygu; Mentese, Emre; Bektas, Hakan
A facile and sensitive method predicated on carrier element free coprecipitation (CEFC) using 2-(2-(2-(4-bromobenzyl)-1H-benzo[d]imidazole-1-yl)acetyl)-N-ethylhydrazine-1-carbothioamide (BIMANEC) is reported for trace determination of Cu(II) and Cd(II) in vegetables and water. BIMANEC was used for the first time for the quantitative determination of these trace heavy metals. Flame atomic absorption spectrometer (FAAS) was used for quantitation. The preconcentration conditions were optimized with respect to pH (8.0), BIMANEC mass (4.0 mg), volume of sample (100 mL), standing time (5 min), and centrifugation time and rate (3 min and 2500 rpm). The influence of potentially interfering ions was scrutinized for the recovery of analyte ions. Under the optimum conditions, the limits of detection (LODs) were 0.51 and 2.28 µg L−1 for Cu(II) and Cd(II), respectively. The relative standard deviations were < 5% for both. The recoveries from the spiked vegetable samples were from 94.9 to 102.8% and from the spiked water samples between 93.2 and 101.6%. Consequently the developed new, facile, rapid, and highly efficient CEFC process was employed for the trace determination of Cu(II) and Cd(II).

Tang, Thomas Li-Ping; Sutarso, Toto; Ansari, Mahfooz A.; Lim, Vivien Kim Geok; Teo, Thompson Sian Hin; Arias-Galicia, Fernando; Garber, Ilya E.; Chiu, Randy Ki-Kwan; Charles-Pauvers, Brigitte; Luna-Arocas, Roberto
Monetary Wisdom asserts that individuals apply their deep-rooted values (the love of money attitudes, avaricious monetary aspirations) to frame critical concerns in the immediate-proximal and omnibus-distal contexts and strategically select certain options to maximize expected utility and ultimate serenity across context, people, and time at the individual, organizational, and national-global levels. This study explores the dark side of decision-making, e.g., avaricious monetary aspirations and corruption (dishonesty). Corruption involves greed, money, and risky decision-making. It is a risky prospect, involving a cost-benefit analysis of self-interest. We frame good or bad barrels in the environmental context as a proxy of high or low probability of getting caught for dishonesty, respectively. We theorize: Two levels of the subjective norm—perceived Corporate Ethical Values at the micro level (CEV, Level 1) and Corruption Perceptions Index at the macro level (CPI, Level 2), collected from multiple sources, jointly impact the magnitude and intensity of the relationships between love of money and dishonesty. Based on 6382 managers in 31 geopolitical entities across 6 continents, our cross-level three-way interaction effect illustrates the following discoveries: As expected, managers in good barrels (high CEV/high CPI), mixed barrels (low CEV/high CPI or high CEV/low CPI), and bad barrels (low CEV/low CPI) display a low, medium, and high magnitude of dishonesty, respectively. Context matters. With high CEV, the intensity is the same across cultures. With low CEV, the intensity of dishonesty is the highest in high CPI entities (risk seeking in the high probability context)—the Enron Effect, but the lowest in low CPI entities (risk aversion in the low probability context). Interestingly, CPI has a strong impact on the magnitude of dishonesty, whereas CEV has a strong impact on the intensity of dishonesty. We demonstrate dishonesty in light of monetary values and two frames of social norms, revealing critical implications to the field of business ethics. This chapter makes robust theoretical and practical contributions to Monetary Wisdom and business ethics.
- MakaleAçık Erişim2024Investigation of Antibiofilm and Antibacterial Properties of Green Synthesized Silver Nanoparticles from Aqueous Extract of Rumex sp.
Akay, Seref; Yüksel, Gamze; Özad Düzgün, Azer
The decrease in the effectiveness of conventional drugs as a result of the growth of resistance to antibiotics has increased the need for innovative tools to control the infections. At this point, metallic nanoparticles, in particular silver nanoparticles, have appeared as a promising method. In the current study, the extract of Rumex sp. (Labada, dock) leaves was used as a reducing agent for the formation of silver nanoparticles. Unlike similar studies, in this study the synthesis conditions were optimized by changing the extract ratio and silver nitrate concentration. Morphological investigations of synthesized silver nanoparticles showed that spherical homogeneous particles at size under 100 nm had been produced. SEM/EDS and FTIR analyses showed that plant components are involved in the synthesis of nanoparticles. It was also determined that higher extract ratio reduced nanoparticle size. The antimicrobial effects of the synthesized nanoparticles against Gram-positive and Gram-negative bacteria were tested, and it was determined that all nanoparticles exhibited activity against both groups. Rumex sp. silver nanoparticles (NPs) were revealed to exhibit antibiofilm activity against three different isolates with moderate and strong biofilm-forming ability. The NPs reduced the biofilm-forming capacity of Acinetobacter baumannii and Klebsiella pneumonaie by 2.66-fold and 3.25-fold, whereas they decreased the Escherichia coli biofilm-forming capacity by 1.25-fold. The investigation of microbial biofilm could play an important role in developing new strategies for treatment options. Our results suggest that Rumex sp. silver NPs may have a high potential for use in the treatment of pathogenic strains.

Cantürk, Zeynep; Özden, Talat; Akinoglu, Bulent G.
Outdoor tests of photovoltaics module are crucial both for marketing and for research and technological developments. The electric generation performance and their degradation rates and lifetime are also related to different climatic conditions of the regions. In this work, the outdoor tests are carried out for six different photovoltaic (PV) modules under Arid-steppe Climate condition of Ankara, Türkiye. Their degradation rates are calculated by using linear regression (LR) and year on year (YOY) methods. The comparison between LR and YOY are carried out and with the other performed studies of different regions of world. In addition, it is investigated that how effective the climatic conditions on daily degradation rates. The results obtained are as follows: Mono-Si and Hetero-junction Silicon (HIT) cell modules degradation rates of 0.71/1.56 %/year and 0.84 %/year are respectively obtained by LR method and 0.57/0.90 %/year and 0.85%/year are respectively by YOY method. The degradation rates for Cupper Indium Selenide (CIS), Cupper Indium Gallium Selenide (CIGS) and microcrystalline Silicon/Amorphous Silicon (µc-Si/a-Si) modules have 1.73/1.49 %/year, 11.55/9.52 %/year and 1.48 %/year for LR method and 1.28/1.12 %/year, 9.94/9.53 %/year and 0.99 %/year for YOY method are obtained respectively. It is also obtained for the Polycrystalline Silicon Modules as 1.20/1.86 %/year degradation rates by LR method and 0.79/1.88 %/year degradation rates by YOY method.

Maden, Nafiz; Doğru, Fikret
The Black Sea, situated between Türkiye, Bulgaria, Romania, Ukraine, and Russia, is tectonically separated into two different sub-basins: Eastern and Western Black Sea. These two sub-basins have been a target of interest for oil and gas exploration for several decades. Although the participation of the Black Sea Basin in the global oil market is very small compared to the Caspian Sea, this basin is considered a potential hydrocarbon deposit since both areas have similar characteristics in terms of source rock. In this study, satellite-derived Bouguer and free-air gravity data were interpreted to disclose the prospective hydrocarbon reservoirs and gas hydrate deposits within the Western Black Sea Basin. The locations of the maxima identified in the I2 invariants map were assessed as five substantial hydrocarbon prospective zones three of which are in the Turkish Exclusive Economic Zone. Numerous oil and gas seeps are evidence of lateral and vertical hydrocarbon migration from the source rock through major faults in the WBSB where the maximum I2 anomalies are observed.

The purpose of this study was to determine the effect of transurethral resection of the prostate (TURP) surgery on quality of sexual life in patients' spouses. A pre/post-operative test, quasi-experimental design with no control group was employed. The research was conducted in the urology clinics of two hospitals in the west of Turkey between 30 June and 30 September 2022. It was completed with 172 patient spouses recruited using non-probability sampling. The study data were collected using an individual information form and the Sexual Quality of Life-Female questionnaire. The preoperative test applied prior to surgery was administered by the face-to-face interview method, while the postoperative test was completed by telephone interviews 8 weeks after the initial data collection. The mean age of the individuals undergoing TURP surgery in this study was 62.69 ± 7.98 years (min 40, max 77), and the mean age of the spouses was 57.91 ± 7.46 (min 39, max 73). Sexual Quality of Life-Female scores after surgery were significantly higher than the pre-surgical values (p < 0.001). A significant difference in sex life quality was determined in terms of age, education, employment status, presence of chronic disease, number of children, and ‘love marriages’ (p < 0.05). The sexual life quality of the spouses of patients exposed to TURP surgery increased significantly 8 weeks after the procedure. The quality of sex life was higher among individuals with higher education levels, working individuals, and those who ‘married for love’, but decreased in line with age and number of children.
- MakaleAçık Erişim2024Evaluation of Cherts in Gumushane Province in Terms of Alkali Silica Reaction
Demir Şahin, Demet
Alkali–silica reaction (ASR) occurs when alkali oxides coming from the cement composition in concrete come together with reactive silica and moisture coming from the aggregate. Additional maintenance and repair costs caused by the development of ASR in concrete cause the cost to increase. However, thanks to the measures taken against ASR in the early period, it contributes to the creation of sustainable and durable concrete structures. The article investigated the usability of cherts with eight different chemical compositions as aggregates in ready-mixed concrete plants in Gümüşhane. Cherts have been investigated for alkaline reactivity and are intended to be used largely as a source for concrete plants. ASR length changes of the samples prepared according to ASTM C1260 standard were determined after 3, 7, 14, and 28 days of the curing period. Microstructural examination, ultrasonic P-wave velocity, and bending and compressive strength experiments supporting ASR were carried out. The obtained test results were compared between the reference (limestone) sample and each other, as well as with the values specified in the standards. The compressive and bending strength values of the samples increase depending on their ASR. It was observed that the crack structures and types increased depending on the increase in the crack values.

Bjelotomić Oršulić, Olga; Varga, Matej; Yalvac, Sefa
A destructive Mw = 6.2 earthquake struck NW Croatia on 29 December 2020, ranking among the most hazardous events in the country in the last century. This study assesses the impact of the earthquake on the permanent geodetic stations of the Croatian national positioning system. Using a novel approach, we combined positioning station data with satellite radar data for the first time in a geodynamic study across Croatia. The analysis involved collecting daily solutions data from 11 nearby network stations as well as multi-temporal satellite images before and after the earthquake. The results reveal a significant co-seismic shift, with the Sisak reference station experiencing the largest displacement of 5 cm to the southeast. Stations up to 100 km from the epicenter exhibited horizontal shifts between 1 and 2.5 cm and vertical shifts between 2 and 4 cm. Satellite images confirmed the co-seismic effects on the permanent stations. The study establishes a strong correlation between geodetic and geological findings, suggesting that vertical displacements result from superficial deposit consolidation in the river plains due to the earthquake shaking, while positional displacement reflects tectonic block movements along the activated strike-slip fault system. The late 2020 earthquake may have further relaxed the accumulated strain on the Mt. Medvednica thrust fault system, which had ruptured in early 2020 with a lower magnitude than expected.

This study was conducted to determine the effects of psychosocial interventions on social functioning and anger levels in forensic psychiatry patients. Data for this meta-analysis study were gathered by searching databases such as PubMed, Web of Science, EBSCOhost, Google Scholar, and YÖK Thesis Center, without any year restriction, from September to December 2023. After a thorough review, 12 studies were deemed appropriate for the analysis. The findings of this meta-analysis indicate that psychosocial treatments administered to forensic psychiatry patients led to an increase in their level of social functioning (SMD: 0.513, 95% CI: 0.072–0.995; Z = 2.280; p <.05) and a decrease in their level of anger (SMD: −0.701, 95% CI: −1.301 to −0.100;Z = −2.287; p <.05). It was also observed that the effectiveness of the psychosocial intervention was not influenced by the type of psychotherapy, the country where the study was conducted, or the duration of the treatment. Psychosocial interventions for forensic psychiatry patients positively affect the mental health of individuals.

The sizes of regions of interest (ROI) obtained from images captured by cameras in palmprint recognition may vary depending on the camera specifications and the position of the hand. The regions of interest that recognition systems can use are typically rescaled through interpolation techniques and then defined as inputs to the system. In such cases, there may be some loss of biometric data. This study aims to enhance the quality of the palmprint ROI images, which are critical for palmprint recognition systems. To achieve this, various super-resolution techniques were employed to reconstruct low-resolution ROI images to the target sizes while preserving the distinctiveness of their biometric features. This approach is designed to optimize recognition accuracy and improve data reliability in palmprint recognition processes.

Researchers have recently been interested in employing nanoparticles (NPs) obtained from herbal extracts through green synthesis for various applications. This study investigated the detoxification of aflatoxins, which are toxic substances produced by molds Aspergillus flavus and Aspergillus parasiticus. The present work examined the levels of aflatoxins in hazelnut and peanut puree. Turkish black tea extract (BTE), Turkish green tea extract (GTE), green synthesized black tea-based iron oxide nanoparticles (BTFeONPs), and green tea-based iron oxide nanoparticles (GTFeONPs) were produced for aflatoxin removal. Characterizations and various antioxidant and antimicrobial activities of the tea extracts and iron oxide nanoparticles (FeONPs) were investigated. The aflatoxin levels of hazelnut puree used for this study were 6.57 ± 0.06 µg/kg for aflatoxin B1 and 13.03 ± 0.16 µg/kg for total aflatoxin, whereas the aflatoxin levels of (AFLB1) peanut puree were 7.79 ± 0.15 µg/kg for AFLB1 and 15.21 ± 0.12 µg/kg for total aflatoxin. Using soluble BTE resulted in a 40 to 50% decrease in aflatoxin levels in hazelnut and peanut purees, while soluble GTE led to a 30 to 45% decrease. Meanwhile, using BTFeONPs and GTFeONPs resulted in a 33 to 48% and 40 to 50% decrease, respectively, in aflatoxin levels in hazelnut and peanut purees.

In this study, we report syntheses, structural and spectroscopic characterizations, and molecular modeling of three novel triazole fused compounds: 4-((4-methoxyphenoxy)methyl)-1-(4-methoxyphenyl)-1H-1,2,3-triazole, 1-(4-isopropylphenyl)-4-((4-methoxyphenoxy)methyl)-1H-1,2,3-triazole, and 1-(4-fluorophenyl)-4-((4-methoxyphenoxy)methyl)-1H-1,2,3-triazole. Their molecular structures and intermolecular interactions were elucidated using single-crystal X-ray crystallography. The compounds crystallize in the P-1 and P21/c space groups with weak C−H∙∙∙N and C-H∙∙∙O interactions. Hirshfeld surface analyses revealed the complex network of intermolecular interactions, determining that in all three compounds, an average of 13 % of the packing interactions were due to hydrogen bonds, and an average of 25 % were due to C-H···π interactions. Since the compounds differ from each other by only one substituent (methoxy, isopropyl, and fluorine) in their phenyl ring, their experimental infrared spectra were clarified by comparing them with the calculated ones. NMR spectroscopy was employed to examine the behavior of the compounds in solution. Conformational scans revealed that the energy differences between conformers are low, indicating potential conformations in which compounds could exist in solution. Nonlinear optical properties were calculated to evaluate the potential of the compounds for optical applications, particularly emphasizing the significantly larger values seen for two compounds compared to a reference compound. Finally, molecular electrostatic potential maps were generated to visualize the charge distribution and potential electrophilic and nucleophilic attack regions.

Öztürk, Serkan; Alkan, Hamdi
In the present study, an evaluation of the region-time-magnitude behaviours of the earthquake occurrences in the West Anatolian Region (WAR), Türkiye, is carried out using the statistical and seis-motectonic parameters such as the b-value of Gutenberg-Richter relation, occurrence probabilities, and return periods of earthquakes. We also have mapped the Coulomb stress changes to observe the current and future earthquake hazard. In recent years, several large earthquakes such as the 1919 Soma (Mw = 6.7) and the 2022 and 2024 Aegean Sea (Mw = 5.3 and Mw = 5.1) revealed earthquake potential in the WAR. Coulomb stress analyses of 41 local events with mostly normal fault mechanisms have shown that posi-tive lobes (> 0.0 in bars) are mainly confined in the crust and uppermost mantle depths around Samos, Kos, and south of Lesvos. The smaller b-values (< 1.0) are observed in the same regions. On the contrary, we have observed a higher b-value from the offshore to onshore, south to north-trending direction, and negative scattered stress lobes (< 0.0 in bars) in slightly NW–SE oriented. The relationship between an increased b-value and negative stress change may indicate a similar seismicity for the region. In addition, we have analyzed the occurrence probabilities and return periods of the earthquakes, which showed us that Mw = 6.0 may occur at 75% in the intermediate term with an estimation of ~7 years. Our results reflect that these types of multiple-parameter assessments are important to define regional seismicity, seismic, tectonic, and statistical behaviours. Consequently, the areas with reductions in b-values and increments in stress imply the possible seismic hazard in the intermediate/long term.

Dogan, Nilgun; Adanacioglu, Hakan
Geographical indications (GIs) are defined as labels that show the relationship of a product with a certain region. They are of great importance in terms of distinguishing these products from the similar ones in terms of the quality that the characteristic features of the region bring to the product, making them stand out commercially, contributing to the rural development and preserving the cultural heritage. Dry beans cultivated by the farmers in the Gümüşhane province is newly recognized as a GI product that is unique in both taste and quality. This study is intended to identify the factors affecting the farmers’ decision to produce GI-labelled dry beans. The survey was conducted in January–March 2021. A sampling size of the participants consisted of 50 farmers who cultivated GI-labelled dry beans and 50 non-GI dry beans. A binary logistic regression analysis approach was employed to identify the factors affecting the likelihood of the farmers cultivating the GI dry beans. The results of the model indicate that the young farmers with the low educational level, the low property land size, the low yield per decare, and the large farmland, the high annual agricultural income and specializing in the dry beans production are more likely to engage in the production of GI dry beans. For the farms involving the GI product, agricultural associations can be advised with the farmers with the wider agricultural acreage and the high annual agricultural income, and that specialize in the production of such products. The participation of the farmers in the agriculture enterprises involving the GI dry beans will depend on them seeing positive widespread effects, which requires a long-term commitment.

Akbulut, Zeynep; Karsli, Fevzi; Dihkan, Mustafa
Ground filtering is an essential process that separates ground and non-ground points for generating digital elevation models (DEMs) from airborne laser scanning (ALS) point cloud data. Traditionally, ground filtering was carried out using rule-based approaches, but with the advancements in deep learning networks, ground filtering can now be performed using these methods. Deep neural networks (DNNs) require large amounts of training samples to reveal key information within the dataset. OpenGF is a new ultra-large-scale dataset which has nearly half a billion points from nine different scenes ranging from highly dense urban areas to steep vegetation covered mountains for ground filtering task. In this study, PointNet++ architecture was employed for ground filtering on the OpenGF dataset. Firstly, we slightly modified PointNet++ architecture’s sampling strategy to decrease the number of duplicate points in the batching process. We proposed a new adaptive tiling strategy based on input point cloud density to cope with highly varying point sampling of the OpenGF dataset. Modified PointNet++ architecture was trained with both adaptive tiling strategy and original OpenGF tiles to investigate the advantages and drawbacks of the proposed strategy on the ground filtering task. To evaluate the performance of the proposed strategy, the results for different test areas were compared with those obtained using the original PointNet++ and rule-based cloth simulation filtering (CSF) algorithms. Despite using fewer epochs, the proposed data collection strategy achieved up to 13% higher accuracy on test scenes with the modified PointNet++ architecture compared to the network trained with original OpenGF tiles.
