Gundogdu, Ali; Bozbeyoglu, Pinar
This study evaluated the performance of a new activated carbon (CCs-AC) produced from corn cobs by boric acid activation for the effective removal of hexavalent chromium, a heavy metal with high potential to pollute the environment, from wastewater. For this purpose, with the help of parameters such as solution pH, contact time, initial Cr(VI) concentration, CCs-AC dose, desorption and temperature, the removal of Cr(VI) ions from aqueous solution by adsorption on CCs-AC was investigated from equilibrium, kinetic and thermodynamic point of view. As a result of the experiments, it was determined that the optimum solution pH was 2.0, the contact time was 4 hours, and the desorption solution was 3.0 M NaOH. From the kinetic data, it was determined that the adsorption was compatible with the pseudo-second order kinetic model and the maximum Cr(VI) adsorption capacity (123.7 mg/g) obtained from the Langmuir isotherm model showed that CCs-AC was of competitive quality with the literature. From the thermodynamic data, the positive ΔH value indicates that the adsorption is endothermic and the value of 12.00 kj/mol indicates that the adsorption is rather chemically driven. The negative ΔG value indicates that the process proceeds spontaneously with an increase in temperature, while the ΔS value indicates an increase in the amount of unused energy.

The purpose of this study is to compare the effects of some parameters on the shooting performance of air rifle shootersin terms of gender and level of competition. To achieve this, 20 air rifle shooters who ranked in the Air Guns Turkey Cup and Air Guns Turkey Championships volunteered for the study. In this study, the height and body composition of the participants were measured, and then grip strength, back and leg strength, heart rate, flexibility, vital capacity, static balance, dynamic balance, and reaction time tests were performed. One (1) series, which included ten (10) shots was fired to determine the shooting success of the participants. There found a positive and high statistical significance between the scoresof the elite shooters in a series of shots and their expected vital capacity measurements (r=.656; p<0.05), between the scores of the junior shooters in a series of shots, their measured vital capacity (r=.820; p<0.01), their vital capacity percentage (r=.686; p<0.05), and their right-hand grip strength (r=.703; p<0.05). Furthermore, while a negative and high significance was acquired between the male participants’ scores in a series of shotsand the right foot dynamic balance (r= -790; p<0.05), there was a positive and high correlation between the scores of female participants in a series of shots and their expected vital capacity (r=.704; p<0.05). As a result, it was concluded that some performance parameters in terms of gender and level of competition affected the shooting performance of the participants.

Bahar, Bilge; Baltaci, Cemalettin; Gençer, Sevil
This study was carried out to evaluate the variations in some quality traits of Tokat red pepper tarhana samples according to the cultivars and drying techniques. For this aim, five white grained bread wheat cultivars such as Altınöz, Candaş, Gökkan, Şahika, and Yakamoz were used as material. And, tarhana samples were dried under open air, airflow oven and vacuum. The study was conducted with three replications according to the split plot design in random plots. All quality traits showed statistically significant variations for the bread wheat cultivars (C), drying techniques (DT), and DT×C interactions. Thus, airflow oven showed the highest values among the drying techniques for the contents of ash (8.5892%), total titration acidity (27.433%) and salt (6.842%). On the other hand, open air drying technique presented the highest values for moisture (14.556%), pH (4.349) and the density of lactic acid bacteria (LAB) (1.4×104 CFU g-1 for M17 agar, 2.4×104 CFU g-1 for MRS agar. Also, Gökkan cv had the highest percents for all quality traits except LAB density. These findings showed that the most suitable bread wheat cultivar for Tokat red pepper tarhana was Gökkan cv, and the most favorable drying technique was open air drying. In addition, it is understood from the results that wheat cultivar and drying technique which used in tarhana production were essential factors. So, tarhana sector should choose the best wheat cultivar and drying technique to be used in tarhana production for consumer taste and healthy diet. From this study, it is understood that the open air drying is the most sustainable technique in terms of both production and consumption.

Başoğlu, Aysel; Akar, Zeynep
A simple, environmentally friendly, inexpensive, and one-step alternative method was reported for the green biosynthesis of silver nanoparticles (AgNPs) operating the Spirogyra sp. extract as a reducing and stabilizing substance. Concentration of AgNO3 and reaction time were optimized to prepare AgNPs under controlled conditions. The synthesized silver nanoparticles were characterized by UV-Vis absorption spectroscopy, fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), energy dispersive X-ray analysis (EDX), and elemental mapping. The TEM analysis showed that the average particle size of AgNPs was 18.3 nm. Structural details of silver nanoparticles elucidated by Selected Area Electron Diffraction (SAED) based on TEM images. In addition, biological activity tests were applied to nanoparticles and algal extracts to determine antioxidant activity (3 different tests: DPPH (1,1-diphenyl-2-picrylhydrazil) radical scavenging activity, total phenolic content (TPC) and total flavonoid content (TFC)) and α-glucosidase enzyme inhibition. Antioxidant activity and α-glucosidase enzyme inhibition values of silver nanoparticles are higher than the values of Spirogyra sp. extracts.

The main focus of this study was to explore the biological activity of metal nanoparticles that were green-synthesized from firethorn fruits. Specifically, iron nanoparticles (Fe-NP) were synthesized from extracts obtained from fruits and seeds of the firethorn plant (Pyracantha coccinea) grown on Gumushane University’s campus for landscaping purposes. The antioxidant and antimicrobial properties of both extracts and synthesized iron nanoparticles were evaluated. To characterize the Fe-NPs, FT-IR spectroscopy, scanning electron microscopy (SEM), and X-Ray Diffraction (XRD) analyses were performed. The antioxidant activity of the fruit extracts and Fe-NPs was assessed using various antioxidant activity tests, including ABTS radical scavenging activity, DPPH radical scavenging activity, ferric reducing antioxidant power (FRAP), total phenolic content (TPC), total flavonoid content (TFC), and total antioxidant content (TAC). The results of all antioxidant activity tests indicated that the iron nanoparticles exhibited higher antioxidant activity than the fruit extracts. Moreover, the minimum inhibitory concentrations (MIC) of the fruit extracts and nanoparticles against Gram-negative bacteria (Yersinia pseudotuberculosis ATCC 911, Escherichia coli ATCC 25922, Proteus vulgaris ATCC 13315, and Pseudomonas aeruginosa ATCC 43288) and Gram-positive bacteria (Streptococcus pyogenes ATCC 19615, Staphylococcus aureus ATCC 25923, and Bacillus subtilis ATCC 6633) were determined the using the medium microdilution procedure. Similar to the antioxidant activity findings, the Fe-NPs demonstrated stronger antimicrobial activity compared to the fruit extracts.

Introduction: Domestic violence during pregnancy is a major public health problem in all countries. The aim of this study is to investigate domestic violence and factors affecting pregnancy. Method: This cross-sectional descriptive study included 747 pregnant women who presented to an outpatient clinic at a maternity hospital in a city in southeastern Türkiye between December 15, 2014 and January 15, 2015. To collect the data, the researchers developed a 25-item questionnaire based on the literature. In the statistical analysis, percentages, means, standard deviations, and chi-square analysis were used, and a value of p<0.05 was considered significant. Results: The mean age of the participants was 26.43±5.4. Of these participants, 7.2% of them reported being physically, emotionally, financially, or sexually abused by their spouse during their marriage, and 2.8% reported being exposed to violence during their current pregnancy. It was found that there was a strong relationship between violence during pregnancy and at the time when the woman wanted to get pregnant, the husband’s involvement in violence, the number of pregnancies, and the history of violence from the husband’s family. To stop violence, families should get training, counseling, family therapy, and help to learn communication. Conclusion: Violence during pregnancy can be caused by a number of factors, such as being exposed to violence during pregnancy, not wanting to get pregnant, the husband’s involvement in violence, the number of pregnancies, and the history of violence from the husband’s family.

Erzincan Tulum Cheese (ETC) holds a significant place among the most popular cheeses in Türkiye. It has been awarded Protected Geographical Indication status, which restricts the allowable milk species, its production area, and specific sheep breed used in its production. Mineral content and antioxidant activity of ETC were aimed to be predicted using conventional FT-NIR and a portable FT-MIR spectrometer combined with partial least square regression (PLSR) and machine learning algorithms based on conditional entropy. Seventy ETC samples were analyzed for their mineral (Al, Ca, Cr, Cu, Fe, K, Mg, Mn, Na, and P) content using ICP-MS. The samples' antioxidant activity was measured using the DPPH•+ scavenging activity method. PLSR combined with FT-NIR spectral data correlated with antioxidant activity (r=0.89) and minerals (as low as r=0.83) except for Cr and Fe. FT-MIR data provided a good correlation for minerals (as low as r=0.82) except for Cr and Mn and a moderate correlation with antioxidant activity (r=0.64). Information theory was applied to select wavenumbers used in machine learning algorithms, and better results were obtained compared to PLSR. Overall, FT-NIR and FT-MIR spectroscopy provided rapid (~ 1 min), non-destructive, sensitive, and reliable output for mineral and antioxidant activity predictions in commercial cheese samples.

Adanacioglu, Hakan; Doğan, Nilgün
Contract farming is a deal between a producer and a buyer regarding cultivation of an agricultural product characteristically. In reality, terms and conditions of these contracts can alter dramatically. It can refer to those arrangements involving public firms, government organisations or NGOs and can also refer to private schemes. In this paper, it is only focused on contract farming on arrangements between farmers and private actors. In recent years, buckwheat has gained increasing notice as a promising functional food, owing to its several human health issues and lack of gluten. This study examines buckwheat farmer’s involvement in contract farming in districts of Gümüşhane province which is in the northeast of Turkey. An empirical analysis of the contract farming regarding the buckwheat farmers and postharvest practice has been provided. The survey was conducted in Kelkit, Köse and Şiran districts as only production places of the buckwheat in the province. Data collected from 30 farmers who are engaged in contract farming model. According to data, issues of the contract farming, marketing channels of the buckwheat and perspectives of the farmers for the buckwheat production with contract farming are addressed. The findings of this study reveal that the contract farming model, mostly eliminates the marketing-related concerns of the farmers in the region. Perceive benefits derivable from beginning to buckwheat contract farming was measured based on the following proposals (the commitments to purchase product, the market guarantee, the compliance with the contract terms, purchasing at the agreed price and timely payment) was evaluated using 5 point likert scale. As a result, buckwheat contract farmers should be monitored by the contract buyer for the continuity of the production.

Öztürk, Serkan; Akkaya, İsmail; Alkan, Hamdi
Çaldıran fault zone (CFZ) are significant seismically active zone that generated many destructive earthquakes. In this fault system, the last of these major earthquakes occurred on 1976 (Ms = 7.3). Therefore, based on the seismotectonic b-value, earthquake probability, recurrence times and Coulomb stress changes, we investigate the future earthquake potential and positive/negative stress changes in this fault zone. The events with a magnitude greater than 3.6 are used to investigate stress transfer direction regarding the seismotectonic parameters. The results indicate that the regions having smaller b-values are obtained along with the SE of CFZ, whilst higher b-values are calculated around the east of Lake Van. On the other hand, the northeast of CFZ represents current stress accumulation. Similarly, the Coulomb stress variations of 1976 earthquake show that stress accumulated at different depths in the northwest of this fault system. In addition, considering the long-term slip rates and horizontal offset in previous studies, the recurrence time of earthquakes has approximately 302 years for a magnitude greater than 6.0. Finally, these comprehensive analyses explain the implications of seismic hazard evaluation and forecasting of possible next earthquake occurrences in this region.

Şimşek, Ahmet Bahadır; Gurkan, M. Edib
The covid-19 pandemic has significantly affected the education sector and raised the new operational challenges that spring from the necessity of planning courses in a way to ensure community safety. Accordingly, many higher education institutions provide guidelines regarding the measures to be implemented in education operations. As such, timetabling of the courses is required to be carried out in line with these guidelines. To address this need, this study introduces a multi-objective mathematical model for a university course timetabling problem under the pandemic-related considerations. In particular, the proposed mathematical model aims to minimize the total number of online courses and sections while considering the balanced distribution of the courses over time slots and days. We test the effectiveness of the proposed model using real-life data. The results show that the proposed approach is able to create an optimal timetable in a reasonable time that addresses the objectives of the faculty administration and satisfies the pandemic-related requirements. The study contributes to the literature by introducing new pandemic constraints and inspires managers facing pandemic guidelines.

Kaya, Afşin Ahmet; Akduman, Öznur; Aksüt, Yavuz Selim
Numerous disasters occur due to the inability to manage risks arising from natural, technological, and human-induced hazards. As a result of these disasters, the magnification of incurred damages underscores the significance of the concept of risk management, an integral step in disaster management. Consequently, efforts to mitigate the adverse effects of earthquakes and other disasters are progressively increasing. However, endeavors aimed at reducing the damages inflicted by earthquakes and other disasters on structures, particularly earthquakes, are not yet at an adequate level. Presently, the importance of alternative solution models to counteract the forces exerted on structures during disasters like earthquakes is on the rise.In this study, unreinforced concrete blocks were coated with flexible polyurea, a state-of-the-art cladding material extensively used in various fields, at different thicknesses. Three-point bending tests were performed on the coated specimens. The data obtained from these tests were analyzed and evaluated. It was concluded that specimens coated with polyurea exhibited higher strengths compared to uncoated specimens. This study introduces the utilization of polyurea flexible composite material in structural elements as an alternative method within the spectrum of precautions taken to enhance the safety of structures against various disasters, primarily earthquakes.

Essential tremor (ET) and Parkinson's disease (PD) are the two most commonly encountered tremor disorders in movement disorders. Diffusion tensor imaging (DTI) is one of the best in vivo ways of mapping white matter pathways in the human brain. The aim of our study was to investigate diffusion variables and cerebellum volume in ET and PD using parcellation methods. Our study included 20 ET, 20 PD and 20 healthy controls. Fraction Anisotropy (FA) and Mean Diffusivity (MD) values were obtained with DTI, while the volume of each lobe of the cerebellum was obtained with T1 images. One-way ANOVA was used for intergroup analysis and Scheffe test was used for post-hoc analysis. Significant differences were found in the diffusion values of the pedunculus cerebellaris, fornix stria, superior longitudinal fasciculus, sagittal stratum, cerebral pedunculus, tapatum and thalamus of ET and PD. Lobule V, Lobule IX, Lobule X volumes of the cerebellum showed significant differences between the groups. Stria thermialis shows involvement of mesolimbic dopaminergic system in PD and it is thought that disruption of strial networks leads to changes in the activity of cerebellar networks and reveals the role of the cerebellum in tremor. It is obvious that cerebellar thalamocortical pathways are affected in Parkinson's disease. In Parkinson's disease, patients should be evaluated for visual processing, conceptualisation, postural instability and gait disturbance to clarify the diagnosis or to differentiate from essential tremor.

Kılavuzlarda hastanın sırtının desteklenmesi, kolun alt kısmının kalp hizasında desteklenmesi ve ayakların yere düz basması önerilmektedir. Ancak bu konuda yapılan çalışma sayısı sınırlı olduğundan, bu önerilerin dikkate alınmamasından kaynaklanan hataların etkileri bilinmemektedir. Bu çalışmada sağlıklı bireylerde kan basıncı ölçümü sırasında kol, sırt ve ayak desteğinin kan basıncı değerlerine etkisinin araştırılması amaçlandı. Araştırmaya 111 kişi dahil edildi. Katılımcıların ortalama yaşları 21.95±1.57 idi. Sistolik ve diyastolik kan basınçları, üçü hatalı ölçüm (desteksiz ayaklar, desteksiz sırt ve desteksiz kol) ve biri kılavuzların önerdiği standart prosedür olan dört ölçüm prosedürü kullanılarak ölçüldü. Prosedürler randomize edildi ve katılımcıların kan basınçları her prosedür için üç kez ölçüldü. Ayak desteği ve sırt desteği olmadan yapılan ölçümlerde belirlenen ortalama sistolik değerler, standart ölçümlerle belirlenenlerden daha yüksek olduğu belirlendi (sırasıyla t=-4.872, p<0.001 ve t=- 2.152, p=0.034). Ayrıca ayak desteği olmadan yapılan ölçümde belirlenen diyastolik değer, standart ölçüme göre yüksek bulundu (t=-5.635, p<0.001). Araştırma sonuçlarına göre ayaklar ve sırt desteksiz bırakıldığında ölçülen ortalama sistolik/diyastolik kan basıncı değerleri standart prosedürle ölçülenlerden daha yüksekti.
