Effect of MWCNT and GNP nanomaterial concentrations on thermal and electrical behavior of copper-based nanocomposites
No full textIn this study, the physical effects of incorporating nano-sized graphene plates (GNP) and multi-walled carbon nanotubes (MWCNT) into a pure copper matrix were examined. Powder metallurgy was used as the composite production method. The microstructures of the nanocomposites were examined, and EDAX elemental and XRD phase analyses were performed. The properties of the electrical resistance and conductivity, thermoelectric properties, and thermal expansion characteristics were determined through various tests. Additionally, the thermal expansion behavior of the composite structures was investigated by measuring the sample sizes before and after the sintering heat treatment. It was observed that as the quantity of nano additives increased, there was a rise in reinforcement agglomeration and porosity. As a result of the experimental study, it was concluded that the addition of MWCNT and GNP nanomaterials to pure copper negatively affected the structural homogeneity of the composite, but positively influenced its electrical and thermal properties.Kimath;rimath;kkale University Scientific Research Projects Unit [2022/104]This experimental study was supported by K & imath;r & imath;kkale University Scientific Research Projects Unit with project number 2022/104
Microplastics in different nasal irrigation options
No full textPurposeWe aimed to assess the presence of microplastics in nasal irrigation methods commonly used in the treatment of sinusitis and rhinitis, and to evaluate human exposure.MethodsA total of 150 samples were included in the study, consisting of nasal wash bottles containing nasal irrigation solution, seawater spray, syringes for nasal irrigation with isotonic solution. The amount of microplastics per millilitre in the samples and patient exposure during single use were assessed separately for each method and product. All samples were filtered using a stainless steel vacuum filter on filter paper with a pore size of 1.2 mu m, washed at least three times with distilled water and incubated at 45 degrees C for 24 h to prevent mould growth. Identification and counting of microplastics was performed using a Leica Flexacam C1 camera connected to an M80 stereomicroscope. The presence of microplastics was confirmed by the hot needle method and Nile red staining.ResultsAn average of 6.49 +/- 13.08 microplastics/product was detected in all filtered samples. The lowest microplastic count was 0 microplastics/product in syringes and the highest was 92 microplastics/product in nasal wash bottles. Significant differences in the amount of microplastics individuals were exposed to during a single use were found between nasal wash bottles and seawater brands, while no significant differences were found between syringe brands. When nasal wash kits, seawater sprays and isotonic nasal rinses were evaluated separately, significant differences were found in the number of microplastics, the microplastics/ml ratio and the number of microplastics exposed during a single use. The highest microplastic exposure was found in nasal irrigation bottles.ConclusionThe exposure of individuals to microplastics increases with medical support treatments, regardless of intranasal or intravenous administration. Due to the inflammation, oxidative stress and proliferation caused by microplastics, new regulations and inspections of production conditions should be implemented worldwide to reduce exposure
Investigación de los niveles de inteligencia espiritual de futbolistas activos
No full textThe aim of this study is to examine the spiritual intelligence levels of active soccer players according to various variables. A survey model was used in this quantitative study. The study group consisted of 517 football players actively playing football in the 1st Amateur League, Super Amateur League and Regional Amateur League. Snowball sampling, a non-probability sampling method, was used to collect the data. The first part of the measurement tool, which consists of two parts, includes questions prepared for the demographic information of the participants. The second part includes the Spiritual Intelligence Scale adapted into Turkish by Erduran-Tekin & Ek & scedil;i (2019). Independent sample test (T-test) and one-way analysis of variance (One-Way ANOVA) were applied to the data obtained. According to the results of the data analysis, Welch values were taken into consideration depending on the homogeneity assumption of the data and Tukey test, one of the Post Hoc tests, was applied as a second level test. The total score and sub-dimensions of spiritual intelligence differ statistically according to marital status, age, occupation, economic income and practicing sports. The fact that football players tell the problems they experience to the people around them (family members), the maturity that occurs in individuals with the advancement of age, the assurance and personal rights they have in the profession, having an economic income that they can feel comfortable and doing sports increase the level of spiritual intelligence
The Relationship Between Intramural Fat Accumulation and Sarcopenia on MR Enterography Exams in Patients with Crohn's Disease
No full textPurpose Research on magnetic resonance enterography (MRE) and sarcopenia for assessing Crohn's disease (CD) is growing. Our study examined the connections between the presence of sarcopenia, intramural fat accumulation (IFA), and clinical, laboratory, and MRE findings. Materials and Methods This retrospective study was conducted on 112 patients with suspected or diagnosed CD who underwent 3-tesla MRE. The study examined the correlation between sarcopenia-related parameters and MRE findings. Results of MRE exams and clinical and laboratory results were statistically analyzed. The Kruskal-Wallis, Pearson chi-square, and Fisher-Freeman-Halton tests were used for comparison. Results It was determined that patients with active inflammation on a chronic basis had more IFA than the others (p<0.001). There were positive relationships between IFA and intramural edema (p<0.001). There were positive correlations between IFA and high b-values and negative correlations with apparent diffusion coefficient values (p<0.05). Positively significant relationships were found between IFA and wall thickness, affected segment length, disease duration, and sedimentation values (p<0.05). Strong correlations were found between sarcopenia and the CD activity index as well as wall thickness (p<0.001/p=0.003). There was no significant relationship between steroid usage and other variables. Conclusion The presence of IFA is associated with chronic inflammation. There was no clear relationship between steroid use and IFA. Our findings support the idea that sarcopenia is related to the activity of CD. Further comprehensive research is required on these subjects
The Anticancer Potentials of Substituted Indeno[1,2-b]quinoline Amines against HT29 and SW620: Experimental and In silico Approach
No full textBackground: This study aimed the determination of the antiproliferative and cytotoxic activities of recently prepared indeno [1,2-b]quinoline amines against colon carcinoma, HT29 and SW620 cell lines by using cell proliferation and cytotoxicity assays. Methods: In vitro inhibition of cell proliferation of indenoquinoline derivatives was determined with an MTT cell proliferation assay. On the other hand, their cell cytotoxicities and apoptotic potential were investigated by LDH cytotoxicity and DNA laddering assays. Moreover, molecular docking studies were performed between the compounds and PDB ID: 1OLG and 4LVT target proteins using virtual scanning techniques. Results: Most of the compounds (1, 3, and 7-9) exhibit much more potent antiproliferative activity than positive controls against HT29 and SW620 cell lines (IC50 values 1.1-4.1 µg/mL) and show slightly toxic properties (percent cytotoxicity 9.8% to 33.5%) to cells compared to positive control. On the other hand, it was determined that effective compounds 1, 2, 3 and 9 stimulated apoptosis on HT29 and SW620. Moreover, the anticancer effect of the recent indeno[1,2-b]quinoline amine derivatives was investigated with the help of molecular docking simulations for their pharmacokinetics. The molecular docking results displayed that mono bromo (1-3) and phenyl (7-9) substituted indeno [1,2-b]quinoline amines interact with mutated p53 and protein Blc-2 residues with hydrogen bonding and polar interactions, respectively. Conclusion: As a result, the preliminary experimental data and in silico studies indicated that the monosubstituted indenoquinoline amine derivatives, especially 1, 3, and 7-9, exhibit effective pharmacological properties. © 2024 Bentham Science Publishers
Modeling of irrigation water quality parameter (sodium adsorption ratio) using hybrid swarm intelligence-based neural networks in a semi-arid environment at SMBA dam, Algeria
No full textSodium adsorption rate (SAR), which significantly affects soil and plant health, is determined according to the concentration of sodium ions, calcium, and magnesium in irrigation water. Accurate estimation of SAR values is vital for agricultural production and irrigation. In this study, hybrid swarm intelligence-based neural networks are used to model sodium adsorption ratio in irrigation water quality parameters in a semi-arid environment at Sidi M'Hamed Ben Aouda (SMBA) dam, Algeria. For this, the nature-inspired optimization techniques of particle swarm optimization (PSO), genetic algorithm (GA), Jaya algorithm (JA), artificial bee colony (ABC), and firefly algorithm (FFA) and the signal processing technique of variational mode decomposition (VMD) have been combined with artificial neural networks (ANN). Correlation matrices were used to select the data entry structure in the established models. Water quality parameters with a statistically significant and medium to high relationship with SAR values were presented as input to the model. The overall performance was measured using various statistical metrics, scatter diagrams, Taylor diagrams, correlograms, boxplots, and line plots. In addition, the effect of input parameters on model estimation was evaluated according to Sobol sensitivity analysis. As a result, the GA-ANN algorithm demonstrated superior performance (MSE = 0.073, MAE = 0.193, MAPE = 0.048, MBE=-0.16, R2 = 0.934, WI = 0.968, and KGE = 0.866) based on the statistical indicators, indicating better results compared to other models. The second-best model, ABC-ANN (MSE = 0.084, MAE = 0.233, MAPE = 0.066, MBE=-0.135, R2 = 0.897, WI = 0.965, and KGE = 0.920) was also selected. The weakest prediction outputs were obtained from the VMD-ANN model. The accurate and reliable estimation of SAR in irrigation water has the potential to facilitate improvements in agricultural irrigation management and agricultural production efficiency for farmers, agricultural practitioners, and policymakers
