Sectarian Diplomacy and the Transformation of Ottoman Statecraft: Yâsincizâde Abdülvehhâb Efendi's Embassy to Qajar Iran (1810-1813)
(MDPI, 2025) Tan, Hasan
At the beginning of the 19th century, Ottoman-Iranian relations entered a new diplomatic phase shaped by Russia's expansion in the Caucasus and Britain's growing influence in the Persian Gulf. This shared perception of external threats led to the establishment of a more structured and representative diplomatic framework between the two empires. This study examines the embassy of Y & acirc;sinciz & acirc;de Abd & uuml;lvehh & acirc;b Efendi, who was appointed as Ottoman ambassador to Iran between 1810 and 1813, in the context of a shifting diplomatic mindset. Y & acirc;sinciz & acirc;de's mission is analyzed not merely as a temporary diplomatic engagement, but as a form of ideological, sectarian, and cultural representation by a figure from the ulema class. Based on archival sources, the study reveals that his diplomatic reports and observations provided critical input to the central administration, contributing to the development of more institutionalized and long-term strategies in Ottoman policy toward Iran. By focusing on the transitional character of his embassy, the paper reassesses the evolving role of religious scholars in Ottoman foreign relations and situates this case between the classical sefaretn & acirc;me tradition and emerging modern diplomatic practices.

Roles of Loneliness and Life Satisfaction in the Relationship Between Perceived Friend Social Support, Positive Feelings About the Future and Loss of Motivation
(Elsevier, 2025) Aslan, Yavuz; Kocak, Orhan; Kaya, Aysel Basmaci; Alkhulayfi, Abdulmohsen Mohammed Abdullah; Gomez Salgado, Juan; Yildirim, Murat
Purpose: University students often face psychological challenges, particularly loneliness and hopelessness, which are exacerbated by factors such as limited social interactions, economic uncertainty, lack of employment opportunities, and the increasing prevalence of online education. This study aims to investigate the relationships among perceived friend social support, loneliness, life satisfaction, and the sub-dimensions of hopelessness, which are positive feelings about the future and loss of motivation. Design/methodology/approach: This cross-sectional quantitative study was conducted with 420 university students who completed a series of self-reported measures, including the Multidimensional Perceived Social Support Scale, the UCLA Loneliness Scale, the Satisfaction with Life Scale, and the Beck Hopelessness Scale. Findings: The findings revealed that perceived friend social support was positively associated with life satisfaction and positive future feelings and negatively associated with loneliness and loss of motivation. Both loneliness and life satisfaction individually and serially mediated the relationships between social support and the dimensions of hopelessness. Conclusion: These results highlight the crucial role of friend-based social support in alleviating loneliness and improving life satisfaction, thereby fostering optimism and preventing motivational decline among students. The findings provide valuable insights for designing interventions to enhance emotional well-being and psychological resilience among university populations.

First report of needle blight of blue spruce (Picea pungens) caused by Neoscytalidium dimidiatum in Turkey
(SpringerLink, 2023) Derviş, Sibel; Türkölmez, Şahimerdan; Güney, İnci Güler; Alkan, Mehtap; Özer, Göksel
The blue spruce (Picea pungens Engelm.) is an exotic conifer species widely used for decorative purposes in landscaping and private gardens. In 2020, 60% of forty blue spruce trees between 20 and 25 years old planted in front of buildings in Kavaklıdere, Ankara, displayed needle blight symptoms. Needles on the lower and interior crown closest to the trunk were infected from the bottoms of branches. They showed a brown-colored or burned appearance before dropping off, starting from their tips, resulting in up to a 65% reduction of the canopy. On the surface of infected tissues, a black-colored fungal mass was observed. Fungal colonies isolated from twenty symptomatic branches and needles were initially dark gray and became black within 4 to 7 days. Zero- to one-septate dark brown conidia (4.6 to 9.8 × 3.6 to 7.5 μm) formed in arthric chains were disarticulating and cylindrical-truncate to rod-shaped, oblong, ellipsoidal, doliiform, or globose, consistent with the description of Neoscytalidium spp. (Crous et al. 2006). The internal transcribed spacer, translation elongation factor 1-α, and β-tubulin loci of a randomly selected isolate (Nd_Pp01) were sequenced using the primers ITS1/4, EF1-728 F/986R, and Bt2a/Bt2b and deposited in GenBank under the accession numbers OK643641, OK666381, and OK666382, respectively. The sequences had 99.77–100% nucleotide identity with those of the type specimen of N. dimidiatum, CBS 145.78. Phylogenetic analysis with concatenated sequences further confirmed the identification. The isolate was deposited in the Bolu Abant Izzet Baysal University Culture Collection with accession number BAIBU-179. A pathogenicity test was conducted with ten 1-year-old P. pungens plants by spraying a conidial suspension (105 conidia/ml) of the isolate Nd_Pp01 onto the needles (Türkölmez et al. 2019). Five seedlings sprayed with sterile water were used as controls. All plants were placed in a growth chamber at 28°C with 70% RH. Spray-inoculated needles initially showed yellow spots within two weeks and turned brown six weeks after inoculation, whereas the controls remained symptom-free. The pathogen was re-isolated from the inoculated needles but not from controls. To our knowledge, this is the first report of N. dimidiatum causing needle blight on P. pungens in Turkey and worldwide (Farr and Rossman 2023).
The Importance of Frontal QRS-T Angle in Predicting the Effectiveness and Success of Thrombolytic Therapy in Patients With Acute Pulmonary Embolism
(Cureus, 2023) Durgun, Mehmet; Karahan, Mehmet Zülkif
Objective: The frontal QRS-T angle (fQRS-T) is associated with myocardial ischemia and ventricular arrhythmias. On the other hand, acute pulmonary embolism (APE) is a major risk factor for cardiac adverse events. This research aimed to determine whether the fQRS-T, a marker of ventricular heterogeneity, can be used to predict successful thrombolytic therapy in patients with APE. Methods: This was a retrospective observational study. Patients diagnosed with APE and hospitalized in the intensive care unit between 2020 and 2022 were included in the research. A total of 136 individuals with APEs were enrolled in this research. The patients were divided into two groups: thrombolytic-treated (n=64) and non-treated (moderate to severe risk, n=72). An ECG was conducted for each patient, and echocardiography was performed. Results: The mean age of the thrombolytic group was 58.2±17.6 years, with 35 females (55.1% of the group) and 29 males (44.9%). The non-thrombolytic group had a mean age of 63.1±16.2, with 41 females (56.5%) and 31 males (43.5%). Respiratory rate, heart rate, and fQRS-T were higher in the thrombolytic group, and oxygen saturation ratio and systolic and diastolic blood pressure were higher in the non-thrombolytic group (p=0.006, p<0.001, p=0.021; p<0.001, p=0.015, p<0.001, respectively). In the thrombolytic therapy group, comparing pre- and post-treatment ECG data revealed a statistically significant change in the fQRS-T value (p=0.019). Conclusion: The fQRS-T may provide important clues for the successful treatment of APEs

Fabrication and characterization of 3,4-diaminobenzophenone-functionalized magnetic nanoadsorbent with enhanced VOC adsorption and desorption capacity
(Environmental Science and Pollution Research, 2021) Ece, Mehmet Şakir; Şahin, Ömer; Kutluay, Sinan; Horoz, Sabit
The present study, for the first time, utilized 3,4-diaminobenzophenone (DABP)-functionalized Fe3O4/AC@SiO2 (Fe3O4/AC@SiO2@DABP) magnetic nanoparticles (MNPs) synthesized as a nanoadsorbent for enhancing adsorption and desorption capacity of gaseous benzene and toluene as volatile organic compounds (VOCs). The Fe3O4/AC@SiO2@DABP MNPs used in adsorption and desorption of benzene and toluene were synthesized by the co-precipitation and sol-gel methods. The synthesized MNPs were characterized by SEM, FTIR, TGA/DTA, and BET surface area analysis. Moreover, the optimization of the process parameters, namely contact time, initial VOC concentration, and temperature, was performed by applying response surface methodology (RSM). Adsorption results demonstrated that the Fe3O4/AC@SiO2@DABP MNPs had excellent adsorption capacity. The maximum adsorption capacities for benzene and toluene were found as 530.99 and 666.00 mg/g, respectively, under optimum process parameters (contact time 55.47 min, initial benzene concentration 17.57 ppm, and temperature 29.09 °C; and contact time 57.54 min, initial toluene concentration 17.83 ppm, and temperature 27.93 °C for benzene and toluene, respectively). In addition to the distinctive adsorptive behavior, the Fe3O4/AC@SiO2@DABP MNPs exhibited a high reproducibility adsorption and desorption capacity. After the fifth adsorption and desorption cycles, the Fe3O4/AC@SiO2@DABP MNPs retained 94.4% and 95.4% of its initial adsorption capacity for benzene and toluene, respectively. Kinetic and isotherm findings suggested that the adsorption mechanisms of benzene and toluene on the Fe3O4/AC@SiO2@DABP MNPs were physical processes. The results indicated that the successfully synthesized Fe3O4/AC@SiO2@DABP MNPs can be applied as an attractive, highly effective, reusable, and cost-effective adsorbent for the adsorption of VOC pollutants.

Can Quercetin Reduce Arsenic Induced Toxicity in Mouse Balb/C 3t3 Fibroblast Cells ? A Study Involving in Vitro, Molecular Docking, and Adme Predictions
(Bmc, 2025) Unsal, Velid; Keskin, Cumali; Oner, Erkan
This study aimed to investigate the protective effect of quercetin against arsenic-induced oxidative damage, inflammation, and apoptosis in mouse BALB/c 3T3 fibroblast cells (NIH-3T3). Arsenic at different concentrations of 0.05 mu M (low), 0.5 mu M (medium), 10 mu M (high) doses were used to induce toxicity, while 120 mu m quercetin was used for treatment. MTT and LDH analyses were performed to determine the effect of arsenic and quercetin on cell viability, while oxidative stress markers and antioxidant enzyme activities were measured by spectrophotometric method. TNF-alpha and IL-1 beta levels were measured by the ELISA method, Autodock programs were used for molecular docking studies. In addition, computer-based analyses of quercetin and succimer molecules were performed using SwissADME web tools. TNF-alpha (PDB ID: 2AZ5), IL-1 beta (PDB ID: 1ITB), Caspase3 (PDB ID: 2XYG), Bax (PDB ID: 4S0O), SOD (PDB ID:1CBJ), GSH-Px (PDB ID: 1GP1) and Bcl-2 (PDB ID: 1G5M) crystal structures were obtained from the Protein Data Bank. Bax and Bcl-2 levels of apoptotic genes and mRNA expression levels of Caspase-3 activity were measured using the QRT-PCR technique. TUNEL staining was performed to determine DNA fragmentations, while DAPI staining was done to visualise nuclear modifications. Quercetin has been found to significantly reduce oxidative stress, inflammation, and apoptosis in cells and exert anti-apoptotic effects. Molecular docking studies revealed quercetin shows good binding affinity with molecules with SOD, GSH-Px, Bax, Bcl-2, Caspase-3, TNF-alpha and IL-1 beta structures, and has been observed to bind with Bax and Bcl-2 with molecular docking scores of -7.5 and - 7.7 kcal/mol, respectively. These findings are supported by results showing that quercetin is effective in anti-apoptotic and anti-inflammatory processes in arsenic-induced cells under in vitro conditions. In addition, when ADME values are examined, it can be considered that quercetin is a useful and effective candidate compound in reducing arsenic toxicity, considering its higher synthetic accessibility score, better pharmacokinetic properties, and good biological transition and interaction capacities compared to succimer.

(Sage Publications inc, 2024) Turk, Omer; Acar, Emrullah; Irmak, Emrah; Yilmaz, Musa; Bakis, Enes
Cancer is a significant public health issue due to its high prevalence and lethality, particularly lung and colon cancers, which account for over a quarter of all cancer cases. This study aims to enhance the detection rate of lung and colon cancer by designing an automated diagnosis system. The system focuses on early detection through image pre-processing with a 2D Gaussian filter, while maintaining simplicity to minimize computational requirements and runtime. The study employs three Convolutional Neural Network (CNN) models-MobileNet, VGG16, and ResNet50-to diagnose five types of cancer: Colon Adenocarcinoma, Benign Colonic Tissue, Lung Adenocarcinoma, Benign Lung Tissue, and Lung Squamous Cell Carcinoma. A large dataset comprising 25 000 histopathological images is utilized. Additionally, the research addresses the need for safety levels in the model by using Class Activation Mapping (CAM) for explanatory purposes. Experimental results indicate that the proposed system achieves a high diagnostic accuracy of 99.38% for lung and colon cancers. This high performance underscores the effectiveness of the automated system in detecting these types of cancer. The findings from this study support the potential for early diagnosis of lung and colon cancers, which can facilitate timely therapeutic interventions and improve patient outcomes.

Activated Carbon-Coated Iron Oxide Magnetic Nanocomposite (ionps@ctac) Loaded With Morin Hydrate for Drug-Delivery Applications
(Frontiers Media Sa, 2024) Dogan, Yusuf; Ozic, Cem; Ertas, Erdal; Baran, Ayse; Rosic, Gvozden; Selakovic, Dragica; Eftekhari, Aziz
Cancer is a major disease that affects millions of people around the world every year. It affects individuals of all ages, races, and backgrounds. Since drugs used to treat cancer cannot distinguish between cancerous and healthy cells, they cause systemic toxicity along with serious side effects. Recently, controlled drug-release systems have been developed to reduce the side effects caused by anticancer drugs used for treatment. Morin is an anticancer drug with a flavonol structure. It has been extensively researched for its antioxidant, anti-inflammatory, antitumoral, and antibacterial properties, especially found in Chinese herbs and fruits, and its multiple positive effects on different diseases. In this study, a nanocomposite with magnetic properties was synthesized by coating biocompatible activated carbon obtained using the fruits of the Celtis tournefortii plant on the surface of iron oxide magnetic nanoparticles. Characterization of the synthesized activated carbon-coated iron oxide magnetic nanocomposite was confirmed by Fourier transform infrared, scanning electron microscopy, energy-dispersive X-ray spectrometry, X-ray diffraction, dynamic light scattering, zeta potential, and vibrating sample magnetometry. The cytotoxic effects of the drug-loaded magnetic nanocomposite were examined in HT-29 (colorectal), T98-G (glioblastoma) cancer cell lines, and human umbilical vein endothelial cell (HUVEC) healthy cell line. The morin loading and release behavior of the activated carbon-coated iron oxide magnetic nanocomposite were studied, and the results showed that up to 60% of the adsorbed morin was released within 4 h. In summary, activated carbon-coated iron oxide magnetic nanocomposite carriers have shown promising results for the delivery of the morin drug.

The Challenges of "renewed" Enlargement To the Western Balkan Countries
(University of Warsaw Centre For Europe, 2024) Yaris, Zelal Basak
In the last two decades, acting as an anchor for a transition to democracy and a market economy, the EU has given membership perspectives to the North Macedonia, Montenegro, and Croatia. At the outset, the EU triggered democratic reforms, empowered civil society organisations, and established democratic rules in those countries. However, on Croatia's joining the EU in 2013, the Union demonstrated what can be best described as apparent enlargement fatigue and took a break from the widening of Western Balkan countries for the fi ve subsequent years. However, the Russian invasion of Ukraine in February 2022 revitalised the EU enlargement policy towards Western Balkan countries for security and geostrategic considerations. In that purview, this paper seeks to explore contextual constraints associated with the EU's renewed enlargement policy towards Western Balkan countries. Using the conceptual framework of Alcaro and his co-authors (2022), it is argued that the EU renewed enlargement operates in a context driven by the following three key processes: (1) multi-actor geostrategic competition; (2) regional fragmentation; and (3) intra-EU contestation. In this context, considering international, regional, and institutional contextual constraints, the EU's leverage on the Western Balkan countries would not be taken for granted, suggesting that the EU needs to develop hybrid strategies transcending classic tools of enlargement.

Development software program for extraction of photovoltaic cell equivalent circuit model parameters based on the Newton–Raphson method
(SpringerLink, 2022) Adak, Süleyman; Cangi, Hasan; Yılmaz, Ahmet Serdar; Arifoğlu, Uğur
Finding the equivalent circuit parameters for photovoltaic (PV) cells is crucial as they are used in the modeling and analysis of PV arrays. PV cells are made of silicon. These materials have a nonlinear characteristic. This distorts the sinusoidal waveform of the current and voltage. As a result, harmonic components are formed in the system. The PV cell is the smallest building block of the PV system and produces voltages between 0.5 V and 0.7 V. It serves as a source of current. The amount of radiation hitting the cell determines how much current it produces. In an ideal case, a diode and a parallel current source make up the equivalent circuit of the PV cell. In practice, the addition of a series and parallel resistor is made to the ideal equivalent circuit. There are many equivalent circuits in the literature on modeling the equivalent circuit of a PV cell. The PV cell single–diode model is the most used model due to its ease of analysis. In this study, the iterative method by Newton–Raphson was used to find the equivalent circuit parameters of a PV cell. This method is one of the most widely used methods for determining the roots of nonlinear equations in numerical analysis. In this study, five unknown parameters (Iph, Io, Rs, Rsh and m) of the PV cell equivalent circuit were quickly discovered with the software program prepared based on the Newton–Raphson method in MATLAB

Developing an Integrated VR Infrastructure in Architectural Design Education
(Frontiers in Robotics and AI, 2020) Aydin, Serdar; Aktaş, Begüm
With the advent of computer technology, Virtual Reality (VR) became an integral part of design studios in architecture education. Researchers have been exploring how VR-enhanced design studios can be assessed from a student-centered perspective. This paper illustrates the role of teaching architectural design for developing a novel and contextual curriculum based on an analysis of student feedback. The background focuses on the development of VR-based architectural design education. The methodology frames two digital design ecosystems which are experimented in four undergraduate courses. With an ecosystem-based approach discussed in this paper, a medium-oriented and a content-oriented curriculum are offered for testing students’ reaction to teaching design in VR. In both ecosystems, students are engaged with advanced digital design methods and techniques, which include 3D form-finding, building information modeling, visual programming, coding, and real-time rendering. The study screens the usage of software solutions for the creation of complex virtual environments, covering Blender, Rhinoceros, Unity, Grasshopper, and Revit. The implementation of a User Experience Questionnaire (UEQ) comparatively demonstrates the performative qualities of both digital design ecosystems. Results indicate that the intensity of interaction varied in two incomparable, but connate, levels of qualities. The findings suggest that the perspicuity aspects of student interaction bare the risk of “complicated” and “confusing” software. The results further demonstrate a conflict between task-related qualities and non-task related qualities. Additionally, interacting with VR tools in architecture design education is found attractive, stimulating, and original despite low scores on the pragmatic qualities of perspicuity, efficiency, and dependability. The data and results obtained from this study give insight into the planning of design studios in architecture education based on the use of VR and digital methods. Therefore, this study contributes to future research in the contextualization of the design teaching efforts.

The prognostic value of ORBIT risk score in predicting major bleeding in patients with acute coronary syndrome
(ScienceDirect, 2023) Günlü, Serhat; Arpa, Abdulkadir; Kayan, Fethullah; Güzel, Tuncay; Kılıç, Raif; Aktan, Adem; Altintaş, Bernas; Karahan, Mehmet Zülkif
Background: The most significant adverse effect of antithrombotic medication in acute coronary syndrome (ACS) is major bleeding, which is related to increased mortality. Studies on ORBIT risk score in predicting major bleeding in ACS patients are limited. Objective: This research aimed to examine whether the ORBIT score calculated at the bedside can identify major bleeding risk in patients with ACS. Methods: This research was retrospective, observational, and conducted at a single center. Analyses of receiver operating characteristics (ROC) were utilized to define the diagnostic value of CRUSADE and ORBIT scores. The predictive performances of the two scores were compared using DeLong's method. Discrimination and reclassification performances were evaluated by the integrated discrimination improvement (IDI), and net reclassification improvement (NRI). Results: The study included 771 patients with ACS. The mean age was 68.7 ± 8.6 years, with 35.3 % females. 31 patients had major bleeding. Twenty-three of these patients were BARC 3 A, five were BARC 3 B, and three were BARC 3 C. Bleeding history [OR (95 % CI), 2.46 (1.02-5.94), p = 0.021], hemoglobin levels [OR (95 % CI), 0.54 (0.45-0.63), p < 0.001], and age > 74 years [OR (95 % CI), 1.03 (1.01-1.06), p = 0.039] were independent predictors of major bleeding. The ORBIT score was an independent predictor of major bleeding in the multivariate analysis: continuous variables [OR (95 % CI), 2.53 (2.61-3.95), p < 0.001] and risk categories [OR (95 % CI), 3.06 (1.69-5.52), p < 0.001]. Comparison of c-indexes for major bleeding events revealed a non-significant difference for the discriminative ability of the two tested scores (p = 0.07) with a continuous NRI of 6.6 % (p = 0.026) and an IDI of 4.2 % (p < 0.001). Conclusion: In ACS patients, the ORBIT score independently predicted major bleeding.

Development of Bread Wheat Lines Resistant To Warrior Yellow Rust (puccinia Striiformis F. Sp. Tritici) in a Short Time With the Use of Biotechnological Methods
(Springer Heidelberg, 2024) Salantur, Ayten; Karaoglu, Cuma; Olmez, Fatih; Kizilgeci, Ferhat; Cetiner, Buket; Turgay, Emine Burcu; Aydogan, Sinan
During the production of bread wheat (Triticum aestivum L.), many diseases affect the yield and quality. One of the most important of these is yellow rust (Puccinia striiformis f. sp. tritici). When this disease creates an epidemic, it causes significant economic losses in wheat. Fungicides are widely used in disease control. In order to reduce the use of fungicides, the breeding of resistant cultivars, which is an environment-friendly and farmer-friendly approach, and the use of these cultivars in production are of vital importance. It is known that the Warrior race of yellow rust, which emerged in Europe in 2011, has overcome many important resistance genes except Yr-15, and wheat cultivars carrying those genes became susceptible. In this study, Yr-15 resistance gene was transferred to Tosunbey, which has high bread quality, with the help of KASP markers and homozygous DH lines were obtained using anther culture. Eighty-four of these lines were taken to the preliminary yield trial together with the Tosunbey standard cultivar. These lines were tested for grain yield, end-use quality and resistance to yellow rust. According to the trial results, 17 promising lines were selected among the Tosunbey-derived Yr-15 lines for advancement in a short period of totally 3 years. If one or more of these selected lines are registered, it will make a significant contribution to both the environment and the country's economy.

Energy-Aware Scheduling in Flow Shops: a Novel Artificial Neural Network-Driven Multi-Objective Optimization
(Taylor & Francis Ltd, 2025) Aslan, Sehmus
Group technology is a managerial strategy used to optimize production by reducing setup times, lead times, and work-in-process inventories. Research on flow-shop sequence-dependent group scheduling problems (FSDGSPs) has primarily focused on minimizing makespan and total flow time to improve efficiency. However, the need for energy-efficient scheduling in FSDGSPs remains underexplored despite increasing sustainability concerns. To address this, the energy-efficient flow-shop sequence-dependent group scheduling problem (EEFSDGSP) is introduced. A novel multi-objective optimization (MOO) technique, the artificial neural network-based multi-objective genetic algorithm (ANN-MOGA), is proposed to minimize makespan and energy consumption in EEFSDGSP. ANN-MOGA advances MOO by using a neural network to evaluate fitness and guide selection, reducing computational complexity versus traditional methods like NSGA-II and SPEA2. A post-processing step (PPANNS) further enhances solution diversity and distribution. Results show ANN-MOGA, especially with PPANNS, outperforms NSGA-II and competes effectively with SPEA2 in larger problem instances.

Interregional comparative analysis of farmers’ perceptions and expectations of climate change
(Italian Journal of Agronomy, 2022) Acıbuca, Veysi; Kaya, Aybüke; Kaya, Tuğçe
This study looked into the relationship and effects of agricultural activities in different regions of Turkey on climate change. This study aims to determine farmer awareness of climate change and its effects, as well as farmer adaptation capabilities in different regions of Turkey against climate change, and to develop extension and policy tools based on the findings. Data were collected through face-to-face surveys with farmers in the provinces where the research was conducted. In this context, a proportional sampling survey of 418 farmers was conducted. The collected information was subjected to factor analysis and the independent t-test. According to the findings, farmers associate climate change with precipitation, and the effect of precipitation and the risks it poses in increasing or decreasing crop yields are of particular concern. Farmers in the Southeastern Anatolia Region are more concerned about heat and drought than farmers in the Mediterranean Region. Furthermore, producers believe that human-caused factors and economic development have a greater impact on climate change than agricultural activities. Farmers in research areas are concerned that climate change will increase migration from rural areas and the decline of forests and animal species. As a result, raising individual awareness and utilising new technology in rural areas is critical. Farmers’ awareness of new and environmentally friendly agricultural techniques must be raised to increase their use. Highlights - Farmers associate climate change with drought. - According to the farmers, the leading factors causing climate change are human-induced factors that disrupt the ecological balance. - The most important concern regarding the effects of climate change is that production costs will increase. - Farmers are reluctant to implement adaptation or mitigation methods that can be developed against climate change.

Endosulfan Elimination Using Amine-Modified Magnetic Diatomite as an Adsorbent
(Frontiers in Chemistry, 2022) Alacabey, İhsan
Pesticides are among the most dangerous developing toxins since they are very hazardous to the environment and threaten human health. In this study, researchers successfully manufactured surface-modified magnetic diatomite (m-DE-APTES) and used them as a sorbent to extract endosulfan from an aqueous solution. There is no other study like it in the scholarly literature, and the results are astounding. Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), energy dispersive X-ray (EDX), electron spin resonance (ESR), and surface area measurements were used to analyze magnetic diatomite particles with surface modification. According to the analysis results, magnetic diatomite has a wide surface area and a porous structure. Furthermore, m-DE-APTES has a higher endosulfan adsorption capacity (97.2 mg g-1) than raw diatomite (DE) (16.6 mg g-1). Adsorption statistics agree with Langmuir adsorption isotherm (R 2 = 0.9905), and the adsorption occurred spontaneously at -2.576 kj mol-1 in terms of ΔGo. Finally, m-DE-APTES are a viable alternative adsorbent for removing pesticides from aqueous solutions.

The Significance of Frontal Plane QRS-T Angle for Estimating Non-Dipper Hypertension
(Cureus, 2022) Evsen, Ali; Karahan, Mehmet Zülkif
Objective: The frontal QRS-T angle (fQRS-T) is linked to myocardial ischemia and ventricular arrhythmias. On the other hand, non-dipper hypertension is a risk factor for cardiac adverse events. The objective of this research was to determine whether the fQRS-T, a marker of ventricular heterogeneity, could be used to predict non-dipper hypertensive individuals in the lack of left ventricular hypertrophy. Methods: The observational study was carried out retrospectively. Patients diagnosed with hypertension were included in this study. Blood tests were routinely conducted for all patients. Electrocardiography (ECG) was conducted for each patient and echocardiography was performed. Blood pressure (BP) values were collected from the ambulatory Holter records. According to ambulatory Holter monitoring, the individuals were separated into two groups. The association between fQRS-T and hypertension was investigated. Results: The research involved 123 patients, with an average age of 51.85±8.22 years, comprising 76 women (61.8%) and 47 males (38.2%). According to ambulatory Holter monitoring, patients were separated into dippers (n=65) and non-dippers (n=58). There were no statistically significant in the laboratory and echocardiographic variables (p>0.05). QT dispersion (QTd) and fQRS-T were substantially greater in the non-dipper group than in the dipper group (p=0.043 and p<0.001, respectively). Independent determinants of non-dipper status were determined by univariate and multivariate logistic regression analyses. fQRS-T was found to be the only independent indicator of non-dipper status (OR: 1.03, 95%CI: 1.02-1.06, p<0.001).

(Taylor & Francis Ltd, 2024) Kacan, Havva; Sakiz, Halis
Child sexual abuse (CSA) is a pervasive problem that can have detrimental effects on the physical and mental health of children, as well as their families. Parents of children with disabilities (CWD) may face additional challenges in protecting their children from sexual abuse. This study aimed to examine the effects of a CSA psychoeducation program for parents of CWD. The program was designed to increase parental knowledge and attitudes towards CSA and prevention strategies, as well as to decrease parents' anxiety regarding the topic. A total of 93 parents of CWD participated in the study, with 45 being randomly assigned to the experimental group and 48 to the control group. The findings suggest that the CSA psychoeducation program was effective in increasing parental knowledge and attitudes towards CSA prevention strategies. The experimental group scored significantly higher than the control group in all domains of the Child sexual abuse knowledge/attitude scale for parents. Additionally, the program was effective in reducing parents' anxiety. This highlights the need for such programs to be implemented in schools and other community settings to increase parental awareness and prevent CSA.
