Objective: In this study, we aimed to examine the perspectives of textile workers on organ donation and related factors. Method: The sample of this descriptive and cross-sectional study consisted of employees of a textile factory located in eastern Turkey (n = 166). The data were collected using the forms Personal Information and determining Knowledge, Awareness, and Willingness regarding Organ Donation and Transplantation. Data collection forms were prepared by researchers based on the literature and taking expert opinion. In the analysis of the study data, number-percentage, chi-square test and Cramér's phi correlation analysis were used. Results: The mean age of the participants was 21.10 ± 2.53, and the numbers of men and women were equal. It was determined that 63.3% of the participants needed education related to organ donation, and 57.8% were willing to donate their organs. There is a correlation the high levels of knowledge, awareness, and willingness regarding organ donation and transplantation with the participant's levels of thinking about donating their organs. Conclusion: Our results supported the view that high levels of knowledge and awareness increased willingness about organ donation. In increasing the number of organ donors, high levels of knowledge and awareness are highly important, all parts of society should be provided with education on this issue, and it should be considered that workers of all sectors, especially textile workers, constitute a significant proportion of most societies in terms of numbers.

Uyanık, Hakan; Ozcelik, Salih Taha A.; Duranay, Zeynep Bala; Sengur, Abdulkadir; Acharya, U. Rajendra
Emotion recognition is one of the most important issues in human–computer interaction (HCI), neuroscience, and psychology fields. It is generally accepted that emotion recognition with neural data such as electroencephalography (EEG) signals, functional magnetic resonance imaging (fMRI), and near-infrared spectroscopy (NIRS) is better than other emotion detection methods such as speech, mimics, body language, facial expressions, etc., in terms of reliability and accuracy. In particular, EEG signals are bioelectrical signals that are frequently used because of the many advantages they offer in the field of emotion recognition. This study proposes an improved approach for EEG-based emotion recognition on a publicly available newly published dataset, VREED. Differential entropy (DE) features were extracted from four wavebands (theta 4–8 Hz, alpha 8–13 Hz, beta 13–30 Hz, and gamma 30–49 Hz) to classify two emotional states (positive/negative). Five classifiers, namely Support Vector Machine (SVM), k-Nearest Neighbor (kNN), Naïve Bayesian (NB), Decision Tree (DT), and Logistic Regression (LR) were employed with DE features for the automated classification of two emotional states. In this work, we obtained the best average accuracy of 76.22% ± 2.06 with the SVM classifier in the classification of two states. Moreover, we observed from the results that the highest average accuracy score was produced with the gamma band, as previously reported in studies in EEG-based emotion recognition.

Nanofluids are considered as smart fluids that can improve heat and mass transfer and have numerous applications in industry and engineering fields such as electronics, manufacturing, and biomedicine. For this reason, blood-based nanofluids with carbon nanotubes (CNTs) as nanoparticles in the presence of a magnetic field are discussed. The nanofluid traverses the porous medium. The nanofluids move on a vertical plate that can be moved. The free convection heat transfer mode is considered when the heat source and heat fluxes are constant. Convective flows are often used in engineering processes, especially in heat removal, such as geothermal and petroleum extraction, building construction, and so on. Heat transfer is used in chemical processing, power generation, automobile manufacturing, air conditioning, refrigeration, and computer technology, among others. Heat transfer fluids such as water, methanol, air and glycerine are used as heat exchange media because these fluids have low thermal conductivity compared to other metals. We have studied the effects of MHD on the heat and velocity of nanofluids keeping efficiency in mind. Laplace transform is used to solve the mathematical model. The velocity and temperature profiles of MHD flow with free convection of nanofluids were described using Nusselt number and skin friction coefficient. An accurate solution is obtained for both the velocity and temperature profiles. The graph shows the effects of the different parameters on the velocity and temperature profiles. The temperature profile improved with increasing estimates of the fraction parameter and the volume friction parameter. The velocity of the nanofluid is also a de-escalating function with the increasing values of the magnetic parameter and the porosity parameter. The thickness of the thermal boundary layer decreases with increasing values of the fractional parameter.

Celik, Erkan; Gul, Muhammet
The world is currently struggling with a new type of coronavirus (2019-nCoV) pandemic that first appeared in Wuhan, China, and then spread to almost all countries. As in other countries of the world, public authorities in Turkey are implementing many preventive and mitigating partial lockdown (PL) actions against the virus's effects. Some decisions and policies implemented before and after March 11, 2020, when the first virus case has been identified, have reduced people and traffic circulation, which has also turned into some improvements in air quality. At this point, this study aims to investigate how this pandemic affects the air quality of a metropolis. A case study of the city of Istanbul, the most affected city with more than half of Turkey's cases, is performed. In our analysis, we observe, compare, and discuss the impact of the COVID-19 pandemic and PL decisions on Istanbul city's air quality. We consider the particulate matter (PM10), sulfur dioxide (SO2), carbon monoxide (CO), nitrogen dioxide (NO2), nitrogen oxide (NO), nitrogen oxides (NOx), and ozone (O3) concentrations. We used data from 19 air monitoring stations (AMSs) and obtained improvements in the air quality for the pandemic period. In summary, the concentration levels in PM10, NO2, NO, and NOx result in a clear decline in pandemic times compared to the normal times in Istanbul. On the other hand, a non-homogenous trend for SO2 and CO concentrations is observed for different AMSs. A partial increase in O2 concentration is obtained in the comparison of before and during the PL period.

This study focused on the biological evaluation and chemical characterization of Malabaila lasiocarpa Boiss. (M. lasiocarpa) (Family: Apiaceae). The phytochemical profile, antioxidant, enzyme inhibitory of the methanolic, aqueous, dichloromethane, hexane extracts were investigated. Based on UHPLC-HRMS analyses, a total of 101 peaks were annotated or identified for the first time in M. lasiocarpa extracts. They include hydroxybenzoic, hydroxycinnamic, acylquinic acids and their glycosides, C- and O-glycosyl and O-diglycosyl flavonoids. In addition, 10 simple mono- and disubstituted coumarins together with 10 furanocoumarins were tentatively annotated. The methanolic extract possessing the highest phenolic (24.36±0.60 mg gallic acid equivalent/g extract) and flavonoid (69.15±0.37 mg rutin equivalent/g extract) content also exhibited the strongest radical scavenging potential against 2,2-diphenyl-1 picrylhydrazyl (21.73±0.42 mg Trolox equivalent/g extract, respectively), and highest reducing capacity (57.81±0.97 and 28.00±0.40 mg Trolox equivalent/g extract, for cupric reducing antioxidant capacity and ferric reducing antioxidant power, respectively). The dichloromethane extract substantially depressed the tyrosinase (73.92±5.37 mg kojic acid equivalent/g extract), α-amylase (0.63±0.01 mmol acarbose equivalent/g extract) and α-glucosidase (0.69±0.02 mmol acarbose equivalent/g extract) enzymes. This study has produced critical scientific data on M. lasiocarpa which are potential contenders for the development of novel phyto-pharmaceuticals.

Hussain, Azad; Arsaln, Muhammad; Rehman, Aysha; Alharbi, Fahad M.; Akkurt, Nevzat; Eldin, Sayed M.; Althobaiti, Saad
The unsteady compressible steam laminar flow associated with heat transfer in fluids in a squared cylinder is examined in this work. The current challenge was created utilizing the CFD approach. The laminar flow is chosen with a low Mach number. With the geometric wall, the flow has a no-slip condition. The pressure on the flow is kept at 0 pas, and the temperature in the flow regime is 305.13. A 0.5 m/s velocity is used to start the flow. With the use of graphics, the effects of time on velocity and pressure distributions are discussed. Different outcomes are also mentioned, such as drag coefficients, lift coefficients, and heat distributions. The velocity drops from 2.5 to 1.6 m/s at t = 7 s in the absence of anybody's force and temperature 305.13 K. Pressure increases from 0.00098 to 0.001 Pas in the flow interval of 10 s. Surface temperature increases from 360 to 375 K in time intervals of 10 s keeping pressure constant. And contour temperature increases from 371.56 to 374.2 K in time intervals of 10 s keeping the pressure constant. This information provides us with caution about the emission of steam from the chimneys of furnaces. It implies that when steam flows from a cylindrical geometry like chimneys of furnaces it heats the upper inner and outer parts which may destroy the material. So for safety, that emission should be taken for a short interval of time otherwise it will result in a havoc process. The lift coefficient remains constant and the drag coefficient increases from 0.0005 to 0.065. Under that condition, fluid has to face more resistance. To overcome that difficulty fluid should be provided with high velocity to continue it for a long time. The technique used to solve modeled problems is the Backward Difference Formula.

Danabaş, Durali; Kutluyer, Filiz; Ural, Mesut; Özçelik, Mehtap; Kocabaş, Mehmet
In aquatic life, environmental chemicals are accumulated by mussels due to their sentinel nature and filter-feeding characteristics. Herein, the present study focused on assessing the concentrations of Cu, Zn, Mg, Mn, Fe, Cd, Pb, Ca, K, and Na levels in freshwater mussels (Unio elangatulus eucirrus) depending on sex and age. For all trace metals, some important differences of bioaccumulations were determined depending on ages and sex. In details, the results indicated that an important age-related accumulation of Mg, Cd, Ca, and K was in females and all trace elements, except Cu, Mg, and K levels in males (p < 0.05). No statistical differences were determined in mean concentrations of Cu, Zn, Mg, and Na. There are statistical differences in Mg, Mn, Fe, and Ca levels between females and males in four aged mussels (p < 0.05). Lead levels were under detectable limits. Overall, metal levels and their toxicity in freshwater mussels should be closely monitored for health of the environment, animals, and humans, since mussels and fish species fed on them are consumed highly in the research region and around.

Tasar, Neslihan
Copper oxide nanoparticle (CuO NP) is used widely in many fields in nanotechnology. For this reason, both production, use, and release to the environment are increasing with each passing day. With the increased use of products that contain nanoparticles (NP) (<100 nm), plants and organisms that constitute the food chain are at risk. In the present study, Phaseolus vulgaris L., a very common food plant, was exposed to metal-based CuO NPs. The anomalies that were caused by CuO NP in germination and mitosis of P. vulgaris were investigated. In the trials, a total of 4 groups (Control, 50, 150, and 300 ppm) were formed and examined in three replications. The determination of the accumulation and elimination rate because of NPs in P. vulgaris that was used in the study was made through X-ray diffraction (XRD), scanning electron microscope (SEM), mapping image, and EDX characteristic spectrum analysis. Also, the mitotic effects on germination, root development, and root tip cells of seeds that were grown by treatment with control, 50, 150, and 300 ppm concentrations were investigated. The study was conducted in three replications in a laboratory setting. All concentrations of CuO NPs caused significant decreases in the mitotic index in the root tip cells of P. vulgaris when compared to the control. The mitotic index reached the lowest level, especially at the highest concentration. Multiple analyzes in the study showed that CuO NPs cause abnormalities in cell division such as C-metaphase, distorted metaphase, distorted anaphase and telophase, chromosome breakage, asynchronous division, advanced chromosomes, micronucleus, and loss of genetic material. These findings also support that the Cytogenetic Test of P. vulgaris can be used to evaluate the genotoxicity of new nanomaterials that are used in many consumer products. In this respect, NPs that are taken up by the organisms in the food chain may pose a danger to higher consumer organisms when they accumulate in the tissue. A control mechanism must be established for the use and contamination of these particles and wider studies must be conducted regarding their effects. Highlights: The effects of CuO nanoparticle, which has a very wide usage area, on root development and mitosis of Phaseolus vulgaris L. plant were investigated in the study. The abnormalities of mitotic division on interphase, prophase, metaphase, anaphase, and telophase were visualized. Evaluation was made considering scanning electron microscopy (SEM) and X-ray diffraction (XRD) results as well.

Integrative production of new nanocomposites has been used to enhance favorable features of biomaterials for unlocking ultimate potential of different molecules. In the present study, advantageous properties of diamond like carbons (DLC) and germanium (Ge) like greater biocompatibility and antibacterial attributes were aimed to combined into a thin film. For this purpose, 400 nm DLC–Ge nanocomposite was coated on the borosilicate glasses via the magnetron sputtering and surface characteristics was analyzed by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and The Raman spectrum. Biocompatibility analysis were performed by 3-(4,5-Dimethylthiazol-2-yl) (MTT) cell viability assay and Hoechst 33258 fluorescent staining genotoxicity assessments on the human fibroblast cell line (HDFa). Finally, antibacterial properties of DLC–Ge nanocomposite coatings were investigated by Pseudomonas aeruginosa (ATCC 27853) and Staphylococcus aureus (ATCC 25923) bacterial attachment analysis. As a result of magnetron sputtering coating, nearly 400 nm thick DLC–Ge nanocomposite film showed a smooth, a non-porous, and a dense characteristic. Cell viability analysis showed that Ge–DLC coatings permits %95 cell surface growth of fibroblast cells. Also, there were no significant difference in aspect of nuclear abnormalities compared to the (−) control which showed nonmutagenic features of the thin film. Finally, antibacterial attachment analysis put forth that Ge–DLC coatings inhibits bacterial adhesion as %40 and %25 rates for P. aeruginosa and S. aureus bacterial strains, respectively. From these results, DLC–Ge nanocomposites could be proposed as a potential new biomaterial for various biomedical applications.

Synthetic pyrethroid pesticide is commonly used in agricultural activities in the Black Sea region during reproduction period of turbot. In this sense, in vivo and in vitro studies have shown that cypermethrin (CYP) could be one of the environmental factors affecting decreasing turbot stocks. In this study, effects of in vivo and in vitro administration of CYP, a synthetic pyrethroid, on sperm kinematics motility (MOT), progressive motility (PM), curvilinear velocity (VCL), straight line velocity (VSL), average path velocity (VAP), linearity (LIN), straight line velocity (STR), amplitude of lateral head (ALH), beat cross frequency (BCF), oxidative stress biomarkers malondialdehyde (MDA), reduced glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and lipid peroxidation (LPO) and also histopathological alterations in gonads were investigated in spermatazoa of turbot (Schopthalmus maximus). Broodstock was supplied from culture origin and used in spawning season, additionally, two (0, 0.187 and 0.218 ppb) and three (0, 1.025, 2.05 and 4.1 ppb) different CYP concentrations were performed for in vivo and in vitro studies, respectively. In vivo and in vitro studies, significant reductions were found in sperm MOT, PM, VCL, VSL, VAP, LIN, and ALH properties depend on the increase in CYP concentrations (p < 0.05). Besides, activities of GSH, GPx, SOD, and CAT increased. In terms of histological alterations, no difference was observed among groups (0, 0.187 and 0.218 ppb) in the maturity stage of the germ cells. According to obtained results, sperm kinematics was affected significantly with increased the dose levels of CYP (p < 0.05).

Basit, Gülden; Erkuş Küçükkelepçe, Gülhan; Arslan Şeker, Sevda
Introduction: Professional values give meaning and direction to clinical practices by providing a philosophical framework for nursing practices. The internalization of professional values is quite effective in providing professional service and is very important in terms of service quality. Design: This descriptive study has been conducted to determine the relationship between nurses' professional values and caring behaviors. Methods: A total of 176 nurses participated who worked in hospitals in this study. The data were collected online using the Nurse Information Form, Nurses Professional Values Scale-Revised (NPVS-R), and Caring Behaviors Assessment Tool Nursing Version-Short Form (CBAN-SF). Data analysis was performed using SPSS software, the Mann–Whitney U test, the Kruskall–Wallis test, and the Spearman correlation coefficient. Results: Of the nurses participating in the study, 66.5% are between the ages of 21–30, 80.7% are female, and 71% are university graduates. No statistically significant difference was found regarding professional values between the mean scores from the NPVS-R and CBAN-SF in terms of the nurses' age, gender, position, working style, clinic at which they work, or their educational status. The nurses scored high on the NPVS-R and CBAN. A moderate, significant, and positive relationship was found between nurses' overall scores on the NPVS-R and CBAN-SF. Conclusion: As nurses' perceptions of professional values increase, their perception toward assessing care behaviors also increases. In addition, a relationship exists between nurses' education levels and assessment of care behaviors and between their work experience and their perceptions of professional values. Conducting studies on the subject using different designs is recommended.

Raza, Ali; Khan, Umair; Eldin, Sayed M.; Alotaibi, Abeer M.; Elattar, Samia; Prasannakumara, Ballajja C.; Akkurt, Nevzat; Abed, Ahmed M.
Given the importance and use of electrically conducted nanofluids, this work aims to examine an engine-oil-based nanofluid including various nanoparticles. In the current study, a fractional model for inspecting the thermal aspect of a Brinkman-type nanofluid, composed of (molybdenum disulfide (MOS2) and graphene oxide (GO) nanoparticles flows on an oscillating infinite inclined plate, which characterizes an asymmetrical fluid flow, heat, and mass transfer. Furthermore, the Newtonian heating effect, magnetic field, and slip boundary conditions were taken into account. The objectives for implementing the Prabhakar-like fractional model are justified because this fractional algorithm has contemporary definitions with no singularity restrictions. Furthermore, the guided fractional model was solved using the Laplace transform and several inverse methods. The obtained symmetrical solutions have been visually analyzed to investigate the physics of several relevant flow parameters on the governed equations. Some exceptional cases for the momentum field are compiled to see the physical analysis of the flowing fluid symmetry. The results show that the thermal enhancement can be progressively improved with the interaction of the molybdenum disulfide-engine oil-based nanofluid suspension, rather than with the graphene oxide mixed nanoparticle fluid. Furthermore, the temperature and momentum profiles enhance due to the factional parameters for molybdenum disulfide and the graphene oxide-engine oil-based nanofluid suspension. This study’s graphical and numerical comparison with the existing literature has shown a very close resemblance with the present work, which provides confidence that the unavailable results are accurate. The results show that an increase improved the heat transmission in the solid nanoparticle volume fractions. In addition, the increment in the mass and heat transfer was analyzed in the numerical evaluation, while the shear stress was enhanced with the enhancement in the Prabhakar fractional parameter α.

Healthcare professionals have a significant role to play in the early diagnosis of child abuse and neglect (CAN), which is important in terms of protecting children's health. The study aimed to measure the change in the participants' level of diagnosing the risks and symptoms of CAN before and after the training by providing a training program to healthcare professionals including the signs of CAN, symptoms and procedures to be followed in this case. All healthcare professionals working in a State Hospital and Family Health Centers in Tunceli, Turkey, and who volunteered to participate in the study were included in the study (n = 125). The data were collected before and after the training by using the Personal Information Form and The Diagnosis Scale of the Risks and Symptoms of Child Abuse and Neglect (DSRSCAN). 39 participants (31.2%) reported that they had previously suspected CAN, and 35 (28%) stated that they had encountered CAN before. The mean DSRSCAN score of the healthcare professionals included in the study before the training was 3.38 (lowest =2.37, highest =3.55), while after the training, it went up to 3.60 (lowest =2.76, highest =5.00), and the difference between the pre-training and post-training DSRSCAN scores was determined to be statistically significant (p < 0.001). It was determined that when healthcare professionals were trained on CAN, their awareness could be further strengthened. Hence, training programs for healthcare professionals on diagnosing and reporting CAN should be updated and increased.

Background: Many implant options could be preferable for fixation after osteotomy in varus knee medial compartment arthrosis. Due to usage characteristics, it is important to compare the biomechanical properties of them. For this purpose, we aimed to examine three different implant types biomechanically in our study. Methods: Ovine tibiae undergoing medial open-wedge high tibial osteotomy were fixed in vitro with three different implants using an angular wedge plate, a metal block plate and an external fixator system. The fixed ovine tibiae were subjected to axial tensile, axial loading and three-point bending tests in a test machine. All biomechanical tests were repeated five times, the maximum and minimum values were ignored, and the average values of the remaining three test results were taken into account. The test results were interpreted after converted into force-elongation curves in Trapezium-X software. Findings: Biomechanical test results revealed some differences between implant types. While the metal block plate had the highest axial tensile strength value, it was the fixation group showing the lowest strength in axial load tests. The used fixator system was the highest strength in axial load tests and the lowest strength in axial tensile tests. Interpretation: Considering the clinically significant forces related to the biomechanical stability of the three different implants used for high tibial osteotomy, the fixator system would appear to be slightly superior, although it should be noted that torsional forces, as well as parameters that could change in living tissue, might affect the results.

The lowest Fe and Zn contents were determined in Dicentrarchus labrax (3.12 ± 0.09 mg/kg) and Pomatomus saltatrix (5.50 ± 0.05 mg/kg). Moreover, the results were evaluated considering the estimated daily intakes (EDI) of these elements for adults. The estimated daily intakes were varied from 0.0101 to 0.0231 mg/kg bw/day for Fe and 0.0178 to 0.0357 mg/kg bw/day for Zn in fish species. In addition, the hazard quotient (HQ) and the hazard index (HI) values were calculated for risk assessment, and it was determined that these values were below 1 for fish species.

Nursel Alp Dal Objective This study was conducted to determine the relationship between gynecological cancer awareness and self-care agency among married women. Materials and Methods This descriptive and cross-sectional study was performed with 819 women who presented to the obstetrics polyclinic of a hospital located in the west of Turkey between December 15, 2020 and April 15, 2021. The data of the study were collected by using the Exercise of Self-Care Agency Scale (ESCA) and the Gynecological Cancers Awareness Scale (GCAS). Results The mean age of the participants was 37.62 ± 9.181 years. The mean ESCA score of the women who participated in this study was 95.89 ± 25.060, which indicated moderate levels of self-care agency. The mean total GCAS score of the participants of this study was 156.57 ± 32.930, which indicated high levels of gynecological cancer awareness among the women. As the self-care agency of the women increased, their awareness of gynecological cancers also increased. Conclusion Midwives and nurses who provide preventive and supportive healthcare services may affect the self-care agency of women positively by gynecological cancer awareness they will raise in these women.

The aim of this study is to assess the toxicity of ibuprofen (IBU) and propranolol (PRO) drugs usingGammarus pulex as a model organism. Firstly, the 96 h LC50 values of IBU and PRO were determined and then three sublethal concentrations of the drugs were exposed to G. pulex. The activities of superoxide dismutase (SOD), catalase (CAT) and acetylcholinesterase (AChE) were evaluated. SOD activity decreased in G. pulex exposed to IBU and PRO compared to control. In all groups exposed to IBU, CAT activity increased at different concentrations at 24 and 96 h. In the groups exposed to different PRO concentrations, CAT activities increased after 24 h compared to the control group (p < 0.05). AChE activities increased in all application groups exposed to IBU for 96 hours (p < 0.05). In conclusion, exposure to IBU and PRO resulted in increased oxidative damage. PRO has been found to cause neurotoxicity.
