    Effect of Al, C and Si doping in boron nitride nanocages (B5N10-NC) to enhance the adsorption of environmental toxic gases: simulation technique in a high-performance gas sensor
    (2024) Mollaamin, F.
    The electronic, magnetic and thermodynamic properties of adsorption of toxic gases, including NO, NO2, and N2O molecules, by using boron nitride nanocages (B5N10_NC) doped with aluminum (Al), carbon (C), and silicon (Si) have been investigated using density functional theory (DFT). Based on nuclear quadrupole resonance (NQR) analysis, C-doped on B5N10_NC has shown the lowest fluctuation in electric potential and the highest negative atomic charge in NO@C-B4N10_NC, NO2@C-B4N10_NC, and N2O@C-B4N10_NC. Furthermore, the reported results of NMR spectroscopy have exhibited that the yield of electron accepting for doping atoms on the X-B4N10_NC through gas molecules adsorption can be ordered as Si > Al > C. Based on the results of (Delta G degrees ads) amounts in this research, the maximum efficiency of Al, C, and Si atoms doping of B5N10_NC for gas molecules adsorption depends on the covalent bond between NO, NO2, N2O molecules and X-B4N10_NC as a potent sensor for air pollution elimination.

    Feasibility of foam concrete using recycled brick and roof tile fine aggregates
    (2024.01.01) Bayraktar, O.Y.; Ahiskali, A.; Ahiskali, M.; Eksioglu, F.; Kaplan, G.; Assaad, J.
    Brick (BR) and roof tile (RT) fine aggregate fractions derived from construction and demolition wastes have a low recycling rate in new construction and building materials. This article assesses their suitability for replacing the limestone aggregate in foam concrete, which helps valorise such fractions and conserve natural limestone resources. Two concrete categories containing or not silica fume (SF) were investigated, while the BR and RT aggregate replacement rates were 10%, 20% and 40%. Tested properties include flow, density, water absorption, porosity, thermal conductivity, mechanical strengths, microscopy, drying shrinkage, resistance to freeze/thaw cycles and elevated temperature. Results showed that the concrete mechanical properties improved when the limestone aggregate was replaced by 10% BR or RT but gradually curtailed at higher addition rates. Such results concorded with the density, water absorption and porosity measurements. Foamed concrete containing BR is more resistant (compared to RT) to drying shrinkage, freeze/thaw cycle, and heat exposure, which was ascribed to the relatively lower BR porosity that improves the concrete mechanical properties and durability.

    (2024.01.01) Wang, X.F.; Yue, X.G.; Kaabar, M.K.A.; Akbulut, A.; Kaplan, M.
    A novel technique, named auxiliary equation method, is applied in this research work for obtaining new traveling wave solutions for two interesting proposed systems: the Kaup-Boussinesq system and generalized Hirota-Satsuma coupled KdV system with beta time fractional derivative. Our solutions were obtained using MAPLE software. This technique shows a great potential to be applied in solving various nonlinear fractional differential equations arising from mathematical physics and ocean engineering. Since a standard equation has not been used as an auxiliary equation for this technique, different and novel solutions are obtained via this technique.

    Effect of Implanted Titanium, Vanadium or Chromium on Boron Nitride Surface for Increasing Carbon Monoxide Adsorption: Designing Gas Sensor for Green Chemistry Future
    (2024.01.01) Mollaamin, F.; Monajjemi, M.
    Adsorption of toxic gas of carbon monoxide (CO) molecules by using transition metals (TM) of titanium (Ti), vanadium (V) or chromium (Cr)-doped boron nitride (B5N10) nanocage have been investigated using density functional theory. The partial density of states can evaluate a determined charge assembly between gas molecules and TM-B4N10 which indicates the competition among dominant complexes of Ti, V, Cr. Based on nuclear quadrupole resonance analysis, TM-doped on B5N10 has shown the lowest fluctuation in electric potential and the highest negative atomic charge including 0.5883 (chromium), 0.6893 (vanadium) and 0.7499 coulomb (titanium), respectively, have presented the most tendency for being the electron acceptors. Furthermore, the reported results of nuclear magnetic resonance spectroscopy have exhibited that the yield of electron accepting for doping atoms on the TM-B4N10 through gas molecules adsorption can be ordered as: Cr > V > Ti that exhibits the strength of covalent bond between titanium, vanadium, chromium, and CO towards toxic gas removal from air. In fact, the adsorption of CO gas molecules can introduce spin polarization on the TM-B4N10 which specifies that these surfaces may be employed as magnetic scavenging surface as a gas detector. Regarding IR spectroscopy, doped nanocages of Ti-B4N10, V-B4N10, and Cr-B4N10, respectively, have the most fluctuations and the highest adsorption tendency for gas molecules which can address specific questions on the individual effect of charge carriers (gas molecule-nanocage), as well as doping atoms on the overall structure. Based on the results of Delta G(ads)(o) amounts in this research, the maximum efficiency of Ti, V, Cr atoms doping of B5N10 for gas molecules adsorption depends on the covalent bond between CO molecules and TM-B4N10 as a potent sensor for air pollution removal. Therefore, for a given number of carbon donor sites in CO, the stabilities of complexes owing to doping atoms of Ti, V, Cr can be considered as: CO@Cr-B4N10 > CO@V-B4N10> CO@Ti-B4N10.

    (2024.01.01) Genç, S.
    Quality and productivity needs are considered together in software. For this reason, any existing software should be tested automatically with test automation. Software test automations is automated software testing activities. Automating constantly manually written tests, on the other hand, saves time, reduces error rates, produces better quality software, and reduces costs. This study aims to produce an automatic unit testing framework that is planned to work in run-time on software products. This developed application performs unit test transformations that can respond to the desired test scenarios on the product being studied.. Java agent is used as the basis of all these transformations. All information about the objects, methods, and variables of the sample java classes to be worked on is converted into data in run-time using byte code. During this transformation, information is saved in the database, and unit tests are created automatically through the template engine. Compared to the products developed on automatic unit test generation in the literature, the opcode parsing method was developed for this study. This method reads a byte code at run-time, uses the properties of the java class it belongs to, and automatically creates the unit test class and test methods. The study can also examine different object definitions and conditional and loop structures within a method and produce alternative test scenarios. The automatic unit test scenario produced has been turned into a flexible framework that can encounter minimum errors at run-time. Considering the scarcity of studies in the field of national software testing; It is thought that the automatic unit test generation product developed within the scope of this study, using byte code, will contribute to the work area.

    (2024.01.01) Mollaamin, F.; Monajjemi, M.
    This article aims to investigate the structural, electromagnetic, and thermodynamic properties of toxic gases molecules including nitric oxide (NO), nitrogen oxide (NO2), and nitrous oxide (N2O) during adsorption on the surface of boron nitride (B5N10) nanocage which has been decorated with aluminum (Al), carbon (C) and silicon(Si) atoms. The results denote that (NO,NO2,N2O) <-> (Al, C, Si)-B4N10 are stable complexes with the most stable adsorption site being the center of the cage ring. The partial density of states can estimate a certain charge assembly between gas molecules and (Al, C, Si)-B4N10 which indicates the competition among dominant complexes of metallic (Al), nonmetallic (C), metalloid/semiconductor (Si). Based on nuclear quadrupole resonance analysis, carbon-doped on B4N10 has shown the lowest fluctuation in electric potential and the highest negative atomic charge including 0.1190, 0.1844, and 0.1312 coulomb in NO <-> C-B4N10, NO2 in NO <-> C-B4N10, and N2O in NO <-> C-B4N10, respectively, can be an appropriate option with the highest tendency for electron accepting in the adsorption process. Furthermore, the reported results of nuclear magnetic resonance spectroscopy have exhibited that the efficiency of electron accepting for doping atoms on the (Al, C, Si)-B4N10 through gas molecules adsorption can be ordered as: Si > Al >> C that indicates the power of covalent bond between aluminum, carbon, silicon and these NO, NO2, N2O towards toxic gas removal from air. In fact, the adsorption of gas molecules can introduce spin polarization on the (Al, C, Si)-B4N10 which indicates that these surfaces might be applied as magnetic scavenging surface as a gas detector. Regarding infrared spectroscopy, doped nanocages of C-B4N10 and Si-B4N10 for NO, Al-B4N10 and Si-B4N10 for NO2, Al-B4N10 and C-B4N10 for N2O, respectively, have the most fluctuations and the highest adsorption tendency for gas molecules which can address specific questions on the individual effect of charge carriers (gas molecule-nanocage), as well as doping atoms on the overall structure. Based on the results of Delta G(ads)(o )amounts in this research, the maximum efficiency of Al, C, Si atoms doping of B5N10 for gas molecules adsorption depends on the covalent bond between NO, NO2, N2O molecules and (Al, C, Si)-B4N10 as a potent sensor for air pollution removal.

    (2024.01.01) Monajjemi, M.; Mollaamin, F.; Shahriari, S.; Mohammadi, S.
    The C-60/Fe3O4/SiO2/GeO2 composite was synthesized containing core/shell/shell nanomaterial by layer/layer gel method. The C-60/Fe3O4/SiO2/GeO2 composite was characterized by X-ray diffraction, field emission scanning electron microscopy fitted through scanning electron microscopy, energy dispersive X-ray spectroscopy, fourier transform infrared spectroscopy, transmission electron microscopy and UV-visible. Magnetic behavior of the synthesized product was evaluated by vibrating-sample magnetometer. The data exhibited that magnetite composites have been properly coated. This system can be applied for recycling photosensitizing way using solar energy for water disinfection. Results were reported and for degradation organic compounds via producing a single oxygen. This approach comprises C-60 amino fullerene as a sensitizer for singlet oxygenation and Fe3O4/SiO2/GeO2 encapsulating magnetite nanoparticles. Fast degradation of furfuryl alcohol and methylene blue under UV-visible light exhibit that this irradiation activity of C-60 amino fullerene-derivatives is related to the photosensitization of single oxygen. Significant single oxygen production using C-60/Fe3O4/SiO2/GeO2 system causes the effective oxidation of and inactivation of MS-2 bacteriophage under UV/visible irradiation. Our results also exhibited that the variable surfaces were effective in photo-catalyst behavior of these compounds. C-60/Fe3O4/SiO2/GeO2 composite can also be recovered and reapplied using a strong magnetic field and the photo-catalyst particles again.

    Interaction of Nano-Boron Nitride Sheets with Electrodes in Lithium Ion Battery for Increasing Voltage and Amperage
    (2024.01.01) Monajjemi, M.; Mollaamin, F.; Shahriari, S.; Khalaj, Z.; Sakhaeinia, H.; Alihosseini, A.
    Nano-Boron nitride compounds have displayed a great potential as anode materials for lithium ion batteries (LIBs) due to their unique structural, mechanical, and electrical properties. The measured reversible lithium ion capacities of Graphene/(h-BN)2/Graphene(G/h-BN/G) based anodes are considerably improved compared to the conventional graphite-based anodes. In this study, the boron nitride sheet has been localized inside the graphene as an option to enhance the electrochemical ratio. Additionally, we have found the structure of G/h-BN/G can improve the capacity and electrical transport in C-BN sheets-based LIBs. Therefore, the modification of BN sheet and design of G/h-BN/G structure provide strategies for improving the performance of BN-G-based anodes. G/h-BN/G could also be assembled into free-standing electrodes without any binder or current collector, which will lead to increase specific energy density for the overall battery design. Finally, we fabricated a novel LIBs and tested our method and we found this system in similar condition using G/h-BN/G increases the voltage and amperage in LIBs. For increasing the capacity, voltage, and amperage for LIBs the composite materials play a strong role. Any theoretical studies in electrode materials (anode and cathode) of lithium ion batteries and subsequent experimental testing with the results of theory can help us to fabricate powerful batteries with low cost. Using Graphene/(h-BN)2/ Graphene(G/h-BN/G) based anodes with a suitable composite for cathode materials exhibit high voltages and amperages compared with similar conditions of the previous LIBs.

    (2024.01.01) Öçal, S.E.; Çetinkaya, S.S.
    Aims: This study aimed to assess the female circumcision (FC) experiences, healthcare needs, and access to health services of foreign university students who are victims of female genital mutilation and studying in Turkey. Methods: This descriptive qualitative study was conducted in the Faculty of Health Science in a state university in Turkey from December 2021 to January 2022. Eight students who had been subjected to FC participated in this study. Data were collected by conducting in-depth, semistructured online interviews and using a pilot-tested interview guide. The data were analyzed using inductive thematic analysis. Results: Four themes emerged: "reasons for performing FC, 'health effects of FC,' 'psychological problems linked to FC,' and 'FC survivors' access to health services.'" Students stated that they exposed to this practice because of limiting their womanhood, they experienced problems, such as pelvic pain, infection, loss of sexuality, fear of pregnancy and birth, and they had healthcare needs due to FC but face some barriers. Conclusions: FC negatively affects women's health and has specific healthcare needs. Studying in a different country can be turned into an opportunity to solve the health problems they experience. For this, the right approach with knowledgeable and culturally sensitive health professionals can change stereotypes towards practice.

    (2024.01.01) Aricak, B.; Cantuerk, U.; Koç, I.; Erdem, R.; Sevik, H.
    Global climate change (GCC) is defined as a process that is considered the most crucial problem of the current century and will affect all living things and ecosystems in the world. In order to specify the potential impacts of this phenomenon, which does not seem possible to stop, it is necessary first to predict the change in climate types. Therefore, the current study aimed to define the shift of climate classifications (according to De Martonne, Erin & ccedil;, and Emberger climate category) in 2040, 2060, 2080, and 2100 for Bursa, one of the largest cities in T & uuml;rkiye, according to the SSPs 245 and SSPs585 scenarios, and compare it with its current situation. As a result, it was determined that the climate types in Bursa province would change significantly and primarily manifest as a shift into arid climate types. It is recommended to take precautions on a sectoral basis to avoid the devastating effects of GCC.

    Social Media Addiction and Emotional Intelligence in Patients with Disorder
    (2024.01.01) Inaltekin, A.; Yagci, I.
    Background: The relationship between depression and severity of social media addiction is likely to be bidirectional. Nevertheless, current studies have addressed the depression score utilizing a scale in the general population instead of assessing this relationship in patients with major depressive disorder. Despite the fact that the negative relationship of social media addiction with emotional intelligence is acknowledged, the existence of this relationship in major depressive disorder has not been investigated yet. Hence, the objective of our study is to evaluate severity of social media addiction and emotional intelligence in major depressive disorder. Methods: This research was performed with 158 participants between the ages of 18 and 56 in Kars Harakani State Hospital Psychiatry Outpatient Clinic. Sociodemographic data form involving the age, gender, marital status, education level and employment status of the participants, Beck Depression Inventory, Bar-On Emotional Quotient Inventory, and Social Media Addiction Scale were implemented to the participants. Results: Creating the group to be none-less addicted and medium-highly addicted with regard to the social media addiction scale score, it was observed that the emotional intelligence of the medium-highly addicted group was significantly lower, and the depression score was higher (P P < .001). Furthermore, the severity of social media addiction had a positive relationship with the depression score and a negative relationship with the emotional intelligence score (r r = 0.353, P < .001; r = -0.376, P < .001). Conclusion: Emotional intelligence in major depressive disorder is associated with both depression level and severity of social media addiction. Interventions, i.e., emotional intelligence skill training, might be practical for the aforementioned patients.
