This article presents an experimental study on the torsional behavior of composite tubes subjected to impact loadings. Four types of composite tubes with the winding angle of 30°, 45°, 60°, and 75° ([±30]FW, [±45]FW, [±60]FW, and [±75]FW) were produced with the filament winding method. Besides, a [0,90]PP composite tube was manufactured with the prepreg wrapping technique. After the composite tubes were impacted at 2.5 J, 5.0 J, and 7.5 J, non-impacted and impacted composite tubes were tested under torsional loading. Contact force–deformation curves of impacted tubes are presented. Torsional moment–twist angle relations for both impacted and non-impacted composite tubes were obtained. In addition, front view and side view of the impacted zone of composite tubes are given. The results showed that sample [±60]FW had the best impact performance with regard to absorbed energy. The impacted samples of [±60]FW and [±75]FW had the lowest torsional strength for each energy level.

Background: Numerous studies have been conducted to identify students’ perceptions of science and scientists since the 1950s. Those studies have revealed that students have stereotypical perceptions, on which teachers may have a significant effect. It is, therefore, essential to determine both teachers’ and students’ perceptions. Purpose: The aim of this study is to investigate students’ and teachers’ perceptions of science and scientists. Sample: The sample for the study consisted of 85 students and 47 teachers who participated in a science festival. Design and methods: The study is based on a descriptive survey model. Data were collected using the Draw-A-Scientist Test (DAST) and Word Association Test (WAT), and analyzed using content analysis. Results: Participants’ drawings focused on scientists’ physical characteristics, type of activity, working environment and the materials used while conducting experiments. A scientist was often depicted as a man in a lab coat with strange hair and eyeglasses and using laboratory materials. Teachers made more detailed drawings of scientists’ working style and environment and more detailed associations with the nature of science, ways of acquiring scientific knowledge and scientific process. Unlike teachers, students emphasized space-related concepts both in their drawings and word associations. Conclusion: This study shows that both teachers and students possess various stereotypical perceptions of scientists aligned with the previous studies. However, the number of scientists drawn as happy and female is higher than the previous studies, which is a promising finding. Moreover, students’ drawings consisting symbols or alternative images that evoked space in particular is one of the several aspects which differentiate this study from most studies. This study also shows that using drawings and word association tests together provides a richer understanding of people’s views of science and scientists than using only one measurement tool. © 2020, © 2020 Informa UK Limited, trading as Taylor & Francis Group.

This study aimed to explore the experiences of the people who underwent orthopedic surgery under spinal anesthesia and to report their feelings and thoughts. The study was carried out using a qualitative approach. Twenty-one patients were interviewed who underwent orthopedic surgery on the first or second postoperative day. Content analysis was performed after the collection of raw data. NVIVO 12 Pro software was used for data analysis. The frequency count (f) and participant codes (P) were used for the presentation of the findings. The themes and frequency counts obtained by analyzing the interviews with the patients were as follows: “Time passed like watching a movie” (f = 213), “Like an adventure” (f = 587), and “See, feel, look” (f = 405). Five of 21 participants (23.8%) stated that they would not recommend spinal anesthesia. The findings generally indicated the anxiety caused by the unknown, fear in the preanesthetic period, operation experienced like an adventure, and a process generally completed with satisfaction. © 2020 John Wiley & Sons Australia, Ltd

Hardfacing coatings involve hard carbide/boride phases dispersed in a relatively soft steel matrix. For the hardness measurements of hardfacing coatings, depending on the micro structure, both the hardness test method and the applied load affect the hardness results; therefore, they affect the wear performance predictions of the coating. For this reason, the proper hardness test method should be determined according to the microstructure of the coating, and the reliability of the obtained hardness data should be established. This study aimed to determine the most suitable hardness test method for hypoeutectic and hypereutectic microstructures of hardfacing coatings by analyzing the reliability of Rockwell-C and Vickers hardness test results. Reliability analyses showed that Rockwell-C is not a suitable hardness test method for hypereutectic hardfacing coatings. Based on the relationship between wear resistance and hardness, Vickers hardness method was found more suitable for the considered materials. © 2019, University of Science and Technology Beijing and Springer-Verlag GmbH Germany, part of Springer Nature.

Prostate cancer is a common health problem among men worldwide and most of these prostate cancer cases are related to a dysfunctional mutant Tumor Protein p53 (TP53) gene. However, the CRISPR/Cas9 system can be used for repairing of a dysfunctional mutant TP53 gene in combination with donor single-stranded oligodeoxynucleotide (ssODN) via cells’ own homology-directed repair (HDR) mechanism. In this study, we aimed to evaluate the CRISPR/Cas9 repairing efficiency on TP53 414delC (p.K139fs*31) null mutation, located in the TP53 gene, of human prostate cancer cell line PC-3 in combination with ssODNs. According to the next-generation sequencing results, TP53 414delC mutation was repaired with an efficiency of 19.95% and 26.0% at the TP53 414delC position with ssODN1 and ssODN2 accompanied by sgRNA2 guided CRISPR/Cas9, respectively. Besides, qPCR and immunofluorescence analysis showed that PC-3 cells, the TP53 414delC mutation of which were repaired, expressed wild type p53 again. Also, significantly increased number of apoptotic cells, driven by the repaired TP53 gene were detected compared to the control cells by flow cytometry analysis. As a result, sgRNA2 guided CRISPR/Cas9 system accompanied by ssODN was shown to effectively repair the TP53 414delC gene region and inhibit the cell proliferation of PC-3 cells. Therefore, the effects of the TP53 414delC mutation repairment in PC-3 cells will be investigated in the in vivo models for tumor clearance analysis in the near future. © 2019, Springer Nature B.V.

Objectives: This study aims to evaluate the interpretation of the antinuclear antibody (ANA)-indirect immunofluorescence (IIF) test results based on the interpreter-related subjectivity and to examine the inter-center agreement rates with the performance of each laboratory. Patients and methods: The ANA-IIF testing was carried out in a total of 600 sera and evaluated by four laboratories. The inter-center agreement rates were detected. The same results given by the four centers were accepted as gold standard and the predictive values of each center were calculated. Results: The inter-center agreement was reported for ANA-IIF test results from 392 of 600 (65.3%) sera, while 154 of 392 results were positive. Four study centers reported 213 (35.5%), 222 (37.0%), 266 (44.3%), and 361 (60.2%) positive test results, respectively. In terms of the patterns, the highest and lowest positive predictive values were 72.3% and 42.7%, respectively, while the highest and lowest negative predictive values were 99.6% and 61.5%, respectively. The agreement for semi-quantitative evaluation at three levels of fluorescence intensity stated by four centers was detected in 100 sera at 87% 3(+), while the other two levels were 6% and 7%. The highest predictive value for the highest fluorescence intensity of 3(+) was found to be 71.9%. Conclusion: Significant differences may be observed among laboratories in terms of qualitative results, patterns, and semi-quantitative determination of the fluorescence intensity in the ANA-IIF testing, particularly at low fluorescence intensity levels and in those with speckled patterns. In case of any discrepancy between ANA-IIF test and clinical prediagnosis, the test should be repeated in another laboratory, if necessary. © 2019 Turkish League Against Rheumatism.

In this study, fractional differential equations having quintic nonlinearity are considered by proposing an accurate numerical method based on the matching polynomial and matrix-collocation system. This method provides an integration between matrix and fractional derivative, which makes it fast and efficient. A hybrid computer program is designed by making use of the fast algorithmic structure of the method. An error analysis technique consisting of the fractional-based residual function is constructed to scrutinize the precision of the method. Some error tests are also performed. Figures and tables present the consistency of the approximate solutions of highly stiff model problems. All results point out that the method is effective, simple, and eligible. © 2019 John Wiley & Sons, Ltd.

This article investigates the competence of ensemble learning techniques in solar irradiance prediction. It was seen from the literature survey, an ensemble tree model, random forests is studied more frequently as ensemble models. However, ensemble of support vector regression (SVR) and artificial neural networks (ANN) is also possible. So, this study is the first detailed evaluation of ensemble models in solar irradiance estimation domain. Boosting and bagging ensembles of SVR, ANN and decision tree (DT), are developed to estimate solar irradiance in hourly basis in five cities in Turkey. First frequently used base models (SVR, ANN, and DT) are created and tested with the use of 5 years meteorological data. Then boosting and bagging ensembles of the base models are developed and tested with the same data. The base models are compared with their ensemble counterparts in terms of average coefficient of determination (R2) and root mean squared error (RMSE). The comparative results show that boosting and bagging ensemble models improve SVR, ANN, and DT in terms of RMSE between 4.6 and 14.6% in average. The results show empirically that ensemble models improve prediction accuracies of various base regression models and it can be applied to other machine learning models used in solar irradiance prediction. © 2019, King Fahd University of Petroleum & Minerals.

Dinoflagellates are a major component of the modern plankton. Of the 2192 species of marine free-living dinoflagellates presently described, an increasing number are being shown to produce resting cysts (probably hypnozygotes) within their life cycle. With rare exception, only the resting cysts fossilize, so they are of central importance in tracing the history of dinoflagellates through geological time. Cysts of many of the more common dinoflagellate species have distinctive morphologies allowing their geographic and stratigraphic occurrences to be traced. An ever-increasing number of taxa are also being shown to produce distinctive and geologically preservable cysts, potentially enhancing our knowledge of the diverse representation of dinoflagellates through time. Here the organic-walled cysts of 73 rare, poorly known or morphologically problematic marine dinoflagellate cyst species belonging to the orders Gymnodiniales (nine species) and Peridiniales (64 species) are reviewed, described and illustrated, and their stratigraphic ranges assessed. The names Echinidinium aculeatum and Echinidinium transparantum are validated herein. © 2019 Elsevier B.V.

We investigated using immunohistochemistry the possible protective effects of ascorbic acid, α-tocopherol and selenium during chemotherapy treatment with cyclophosphamide. Thirty female Wistar rats were divided into five groups of six: group 1, untreated control; group 2, 75 µg/kg cyclophosphamide; group 3, 75 µg/kg cyclophosphamide + 150 µg/kg/day α-tocopherol; group 4, 75 µg/kg cyclophosphamide + 200 µg/kg/day ascorbic acid and group 5, 75 µg/kg cyclophosphamide + 40 ppm/kg/day selenium. Proliferating cell nuclear antigen (PCNA) staining was used to detect cell proliferation and AT1 was used to evaluate structural damage. Caspase-8, caspase-9 and caspase-3 signal molecules were used to investigate apoptosis. In group 2, epithelium, alveolar macrophages, infiltrated lymphocytes and connective tissue were immunostained moderately to strongly with PCNA. Bronchus, alveolar wall and infiltrated lymphocytes were immunostained moderately to strongly with AT1 and diffuse strong caspase immunoreactions were observed throughout the lung tissue. AT1 and caspase immunoreactions in groups 4 and 5 were similar to group 2. In group 3, PCNA immunoreactivity was strong in the bronchiolus epithelium, endothelial cell nuclei and in stacks of infiltrated lymphocyte cell nuclei. In group 3, AT1 and caspase immunoreactions were identical to group 1. It appears that α-tocopherol inhibits lung tissue damage in rats during chemotherapy. © 2020, © 2020 The Biological Stain Commission.

Head lice infestation caused by Pediculus humanus capitis de Geer, 1767 is one of the most common public health problems. the relationship between humans and head lice dates back millions of years ago that differentiated into different phylogenetic clades. Treatment of head lice infestation usually based on insecticide-based products, which promotes the resistance in the head lice populations. in the present study, we aimed to screen the presence of permethrin resistance among collected P. h. capitis specimens in Turkey. Three mutation sites (T917I, L920F, and M815I) were screened using real-time PCR and resistance was identified by melt analysis. of the studied specimens, resistance allele frequency (RAF) was found 0.98 for T917I, 0.99 for L920F, and 1.00 for M815I. the phylogenetic study revealed that Clade A and Clade B are present and overlap in Turkey. the present study is first to screen the resistance among Turkish head lice specimens. To not stimulate the pyrethroids resistance in head lice populations, early detection of resistance is crucial and will help the health professionals to choose suitable formula in the treatment. We suggest that the resistance status needs to be screened in randomly selected populations before any treatment application is given., Scientific Research Project Fund of the University of Health Sciences [2018/067], We thank Dr. Suha Kenan Arserim, Prof. Dr. Seray Toz and Prof. Dr. Yusuf Ozbel for their valuable helps.

Nanotechnology has become one of the most popular areas of interdisciplinary research. In the vast majority of nanotechnology applications, polymer-based matrices were used as the dispersing medium of nanoparticles. The combination of polymer–zeolite nanocomposite has the potential to come out with the advantages of polymers and zeolites while coping with the deficiencies of both materials. In this study, the synthesis and properties of low-density polyethylene (LDPE) composites with nanozeolite + Y2O3 are investigated. Polyethylene nanocomposite fibers containing nanozeolite + Y2O3 at 5% by mass using a melt extrusion method were composed in a laboratory type twin screw extruder. The thermal properties of the composite fibers were determined by analysis of both thermal gravimetric and differential thermal spectra. Their structural properties were enlightened by scanning electron microscopy, Fourier transform infrared, and ultraviolet absorption. According to the results of X-ray diffraction tests, the samples contain crystals in semicrystalline and α form. The mechanical properties of LDPE matrices increased with the addition of nanoparticles. In addition, radioluminescence properties of the polymer were also improved after composing with nanozeolite and Y2O3.

The use of supercritical carbon dioxide as a working fluid is an important alternative to enable the use of parabolic collectors in the high-temperature applications field. In the present paper, the effects of carbon black nanoparticles dispersed in supercritical carbon dioxide (sCO2) base fluid on the energetic and exergetic performance of parabolic trough collectors are theoretically investigated. Thermal modeling and performance analyses are performed through the developed model in the Engineering Equation Solver software. To present operating conditions of the system, all working fluids are tested under a pressure of 80 bar at a mass flow rate of 1.1 kg/s. In these analyses, the fluid inlet temperature, ambient temperature, and nanofluid concentration are determined as the variable indicators. Up to approximately working fluid inlet temperature of 705 K, the exergy efficiencies of the concentrating collectors using the sCO2 nanofluids are higher than that of the concentrating collector using the sCO2 base fluid. Additionally, the exergy efficiency increases in the systems using nanofluids with 2% and 4% concentration ratio are between 0.34–6.96% and 0.49–11.44%, respectively, according to the system using base fluid. Besides, at the working fluid inlet temperature values greater than 705 K, the exergy efficiency of the collector of using the sCO2 working fluid is found higher than the collectors using the nanofluids. However, at the same working fluid inlet temperatures, the fluid outlet temperatures of the collectors with the sCO2 nanofluids are higher than the system with sCO2 working fluid. © 2020, King Fahd University of Petroleum & Minerals.

Tuberculin skin test (TST), which is used in the diagnosis of latent tuberculosis infection, may cause Koebner's phenomenon and false-positive results in psoriasis patients. The purpose of this study is to compare TST with QuantiFERON-TB Gold Plus (QFT-plus) test in psoriasis patients and to determine the effects of psoriasis on TST results. Ninety-two psoriasis patients and 30 control subjects were included in the study. QFT-plus test, TST, and prick test to distinguish the increase of induration because of the skin trauma were performed on both groups. The demographics, risk factors for latent tuberculosis infection, BCG vaccination history, Koebner's history, psoriasis severity, and treatment history of the patients were recorded. The effects of these variables on test results were investigated by comparing those with control group. The criteria of National Tuberculosis Diagnosis and Treatment Guidelines were used in the evaluation of test results, and threshold value of positivity for TST was taken as 10 mm in BCG-vaccinated patients who are planned to start biological treatment. Prick test results were negative in the control group. There was no significant relation between the results of prick test and TST induration diameters in the patient group. Although TST positivity was significantly higher in patients (62%) compared with control group (33%), QFT-plus test results were not statistically different between two groups. Agreement between two tests was determined to be low in patient group with 48% (K = 0.1), and it was determined to be moderate with 77% in control group (K = 0.4). QFT-plus test was found to be negative in 46 of 57 TST-positive patients (80.7%) in patient group. It was determined in both groups that vaccination did not have any effect on test results. When threshold value was lowered to 5 mm in patient group without considering BCG reaction, the number of TST-positive patients increased from 57 to 65. Mean TST induration diameter was 10 mm and 14 mm in cases with mild and moderate to severe clinical manifestation, respectively (P =.04). However, no effect of disease period and treatment was determined on both test results. TST positivity was higher in psoriasis patients compared with control group. It was considered due to the increased reaction of the skin to mycobacterial antigens rather than the Koebner's response. Although TST results were not affected by BCG, it was concluded that a 10-mm threshold value of positivity was a suitable approach in order to reduce the number of patients receiving unnecessary preventive treatment in patients who are considered to initiate biologic agents. Furthermore, it was also concluded that QFT-plus test may be preferred in psoriasis patients since it is applied in vitro and its specificity is higher and not affected by disease severity. © 2020 Wiley Periodicals LLC

We report a detailed structural analysis and properties of the photoluminescence (PL) and thermoluminescence (TL) spectra of Eu3+ and Dy3+ incorporated into novel La2MoO6 and La2Mo2O9 phosphors synthesized successfully through gel combustion synthesis. the formation of a tetragonal phase and a cubic structure were verified for La2MoO6 and La2Mo2O9 phosphors via X-ray diffraction (XRD) studies. Dy doped samples exhibited blue and green emissions at 480 nm (F-4(9/2) -> H-6(15/2)) and 572 nm (F-4(9/2) -> H-6(13/2)), and also Eu doped samples showed a sharp emission peaks at 612 and 619 nm (D-5(0) -> F-7(2)) upon 349 nm pulse laser excitation. Peak shape (PS) technique was utilised to determine activation energy, frequency factor and order of kinetics associated with the main glow curves in undoped and Eu and Dy doped samples after X-ray irradiation. the present findings suggest that Eu and Dy incorporated La2MoO6 and La2Mo2O9 phosphors are highly auspicious candidates for applications in solid-state lighting.

Objective: To investigate serum cortistatin levels in women with gestational diabetes mellitus (GDM) and women with uncomplicated pregnancies. Material and methods: This case-control study consisted of 40 pregnancies with GDM and 41 healthy singleton pregnancies matched for maternal and gestational age. The maternal serum levels of cortistatin were measured with enzyme-linked immunosorbent assay and compared between groups. Results: Cortistatin levels were significantly lower in GDM group (48.85 ± 20.18 versus 65.84 ± 33.98 ng/ml, p =.008). There was a statistically significant difference in cortistatin levels between different treatment modalities and control group (χ2(2) = 8.828, p =.012). Pairwise comparisons showed that diet group had significantly lower CST levels than control group (p =.012). Serum cortistatin levels were negatively correlated with serum insulin and glucose levels and HOMA-IR (r = −0.358, p =.001; r = −0.303, p =.006; r = −0.444, p

Objective: Perlecan is an extracellular matrix proteoglycan suggested to maintain endothelial functions. We aimed to measure maternal serum perlecan levels in different preeclampsia phenotypes. Methods: This study included 50 women with preeclampsia and 30 healthy pregnant women. Results: Serum perlecan levels were significantly higher (p = 0.016) in preeclamptic women with severe features(n = 23) than preeclampsia patients(n = 27). There were no statistically significant differences in serum perlecan levels between the early-onset preeclampsia(n = 25), late-onset preeclampsia(n = 25), and healthy pregnancies. Conclusion: Our findings suggest that preeclamptic women with severe features have higher serum perlecan levels than women with preeclampsia. © 2020, © 2020 Informa UK Limited, trading as Taylor & Francis Group.

The un-doped, Tb3+ and, Dy3+ doped LiMgPO4 phosphors were successfully synthesized by the sol-gel method. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were employed to characterize the light-emitting phosphors. The XRD spectra verify the phase formation of samples. The luminescence properties were analyzed by radioluminescence (RL), photoluminescence (PL), cathodoluminescence (CL) and, thermoluminescence (TL) spectra. Also, the effect of Tb3+, Dy3+ ions in LiMgPO4 was determined on the luminescence intensity in detail. The RL spectrum of un-doped LiMgPO4 consists of two broad emission bands in the 310–450 nm and 575–850 nm range. The maximum intensities of these bands were observed at 360 nm and 655 nm. The emission spectrum of Dy3+ doped LiMgPO4 under X-ray excitation show characteristic emissions of Dy3+ corresponds to 4F9/2→6Hj transitions. In addition to the 5D4→7Fj (j:6–1) transitions of Tb3+ doped LiMgPO4 phosphor, strong emissions derived from 5D3→7Fj (j:6–3) transitions were observed in the blue region. Also, these blue emissions were seen at RL, PL and, CL spectra. The optical absorption spectra were recorded and the energy band gaps were calculated 3.62 eV, 3.30 eV and, 4,01 eV for un-doped, Dy3+ and, Tb3+ doped LiMgPO4 phosphors, respectively. The phosphors irradiated with UV (254 nm) light. The main TL glow peak was observed at 288 °C for the Dy3+ doped phosphor, and the peaks at 198, 283 °C were observed for the Tb3+ doped phosphor. © 2020 Elsevier B.V.

Background: Cutaneous squamous cell carcinoma (cSCC) is a malignant and invasive tumor which is originated from epidermis with a high incidence among non-melanoma skin cancers. The aim of this study was to determine whether vitamin D receptor (VDR), calcium-sensing receptor (CaSR) and beta catenin (β-catenin) proteins have an effect on cSCC. Materials and methods: VDR, CaSR and β-catenin proteins in tissue samples of cSCC and control group were analyzed by immunohistochemistry (IHC) and Western blotting (WB) method. IHC findings were statistically evaluated. Results: IHC staining density of VDR and β-catenin were higher in cSCC tissue samples than control. The difference between IHC staining density of VDR and β-catenin in the patient and the control groups were statistically significant (p = 0.021, p = 0.021, respectively), but not for CaSR (p = 0.237). While the VDR and β-catenin staining rates obtained by the IHC method could be supported by WB results, the WB bands for CaSR could not be shown. Conclusion: The findings suggest that VDR and β-catenin may have an effect on the disease. Further research is required to better understand the role of VDR and β-catenin together on cSCC. © 2020 De Gruyter. All rights reserved.

In this work, the pneumocardiogram signals of nine rats were analysed by scale index, Boltzmann Gibbs entropy and maximum Lyapunov exponents. The scale index method, based on wavelet transform, was proposed for determining the degree of aperiodicity and chaos. It means that the scale index parameter is close to zero when the signal is periodic and has a value between zero and one when the signal is aperiodic. A new entropy calculation method by normalized inner scalogram was suggested very recently. In this work, we also used this method for the first time in an empirical data. We compared the both methods with maximum Lyapunov exponents and observed that using together the scale index and the entropy calculation method by normalized inner scalogram increases the reliability of the pneumocardiogram signal analysis. Thus, the analysis of the pneumocardiogram signals by those methods enables to compare periodical and/or nonlinear aspects for further understanding of dynamics of cardiorespiratory system. © 2020, Springer Nature B.V.

Traditional and additive free conservation techniques for long shelf life of fruits can be counted as drying and canning or processing to jam–marmalade. Conventional systems consume fuel or electricity to produce required energy with low efficiency due to losses and irreversibilities through heat transfer. For strawberry jam production, heat is applied as a batch system by vacuum-jacketed agitated vessel with a water or heating oil (heat transfer fluid—HTF), which is heated by electricity inside the jacket. In this study, energy and exergy efficiencies of conventional jacketed vessels and inductive heater were compared theoretically for jam processing. It is found that water and HTF used systems works with 82.27% and 93.38% energy efficiencies, respectively, while inductive processing system works with 95.00% efficiency. In terms of irreversibilities, the inductive system generates 79.90 kJ K−1 entropy, while other systems generate 674.19 kJ K−1 for HTF system and 753.90 kJ K−1 for the water system. It is determined that the batch system with induction heater needs less energy and exergy input than conventional electrical heater systems to provide the same desired output. Direct heating by induction heater has several benefits at thermal food processing systems as strawberry jam production by lowering energy and exergy losses.

This work compares an energy cost and an energy consumption results of the 4 wt.% cupper mixed aluminum based powder metal (PM) compacts processing under induction or furnace heating. Total power and energy consumptions and total energy costs per kilogram and compact have been analyzed. T6 precipitation heat treatment applications have been applied with two different methods, one with 2.8 kW, 900 kHz ultra-high frequency induction heating system (UHFIHS), other with 2 kW chamber furnace. In the first method, Al-Cu PM compacts have been heated by induction at 580 °C in one minute and then cooled down by water. Afterwards, the samples have been heated 170, 180, 190 and 200 °C respectively for artificial ageing and cooled naturally. In the second treatment, unlike the first study, Al-Cu PM compacts are heated by chamber furnace at 540 °C in 5 hours and cooled by water. Then PM compacts are artificially aged at 190 °C in 10 hours with same furnace. During both processes, energy and power consumptions for each defined process have been measured. Optimum heat treatment of the induction is determined. The cheaper energy cost is obtained by the induction heat treatment. © 2020 Authors. Published by association for ETRAN Society.

In work environments, it is essential for engineers to have a high level of teamwork competence. Therefore, engineering education programs aim to provide an environment where students can experience working in teams. In this study, perceptions and co-regulation of computer engineering students regarding teamwork were examined in a hardware course. Ateamwork oriented approach based on individual and group reflections of students was designed and applied during an 8 week project study with the participation of 56 sophomore students of a public university in Turkey. In order to analyze different aspects of the teamwork acquisition process, convergent parallel mixed-methods design was utilized by using both quantitative and qualitative data. Quantitative data were collected by co-regulated learning questionnaire which was applied as pretest and posttest, and teamwork evaluation form that was used for self and peer assessment. Qualitative data were gathered by reflections and focus group interviews. The findings indicated that teamwork oriented approach had significantly increased co-regulation skills of students and they gained positive perceptions towards teamwork. Since most of the teamwork studies in computer engineering programs have been conducted in software engineering courses, applying a teamwork oriented approach in a hardware course provides a valuable contribution to the literature. © 2020 TEMPUS Publications.

In this study, the effect of different case-hardening treatments on microstructure, hardness distribution, surface roughness parameters, and dimensional changes was investigated for helical-toothed gears made of 16MnCr5 and 21NiCrMo2 steels. Gas carburizing, gas carburizing–double quenching, low-pressure carburizing, and plasma-nitriding treatments were performed as case-hardening processes. The surface characteristics and distortion analyses of the case-hardened helical gears were examined using an optical microscope, hardness tester, profilometer, and micrometer. In order to ensure adequate pitting and bending strength, the required minimum effective case depth and minimum total case depth values were provided by the performed case-hardening treatments. In the gears, the largest dimensional increase after the heat treatments occurred at the end of the gas carburizing due to the long treatment times at high processing temperatures. The surface roughness values obtained through all performed case-hardening treatments necessitated the finishing processes. © 2019, The Indian Institute of Metals - IIM.

It is important to enhance the availability of SACs either in cloudy weather or after sunset for space heating and agricultural drying process. In this context, this study aims to determine experimentally thermal performance of cherry pits as sensible heat storage material under natural convection conditions. In the first collector (Type I), powdered cherry pits (32 kg) were used as heat storage material and cherry pits (24 kg) were used in the second (Type II). The third collector (Type III) with a flat absorber plate is for comparison. Although the maximum thermal efficiencies were found 26.54% and 27.03% for Type I and Type II respectively, average thermal efficiency of Type I is higher than Type II. According to the test results, the inlet-outlet temperatures were equalized 46 min for the Type III, 200 min for Type II, and 270 min for Type I collector after sunset. As a result, it can be said that the use of cherry pits and powder as sensible heat storage material is promising. © 2018 Elsevier Ltd Celal Bayar Üniversitesi: 2016-151 This research paper was supported by Manisa Celal Bayar University, Scientific Research Project Office.

Methods: The 140 patients in this study were assigned to the intervention group (n = 70), which received a 10-minute hand massage before cataract surgery, and to the control group (n = 70), which received routine nursing care. The visual analog scale (VAS) and Spielberger State-Trait Anxiety Inventory (STAI) were used to collect data. Findings: The median STAI state scores of the intervention and control groups were found to be 46.0 (44.7 to 48.0) and 57.0 (55.75 to 59.00), respectively. The VAS comfort score of the intervention group after hand massage (4.0 [1.7-5.0]) was lower than that of the control group immediately before surgery (8.0 [6.0-10.0]) (P < .05). In addition, except oxygen saturation, the remaining vital signs were lower in the intervention group. Conclusions: Hand massage reduced the anxiety of patients, positively affected their vital signs, and increased their comfort. © 2019 American Society of PeriAnesthesia Nurses

Today, increasing energy demand and human consumption are becoming increasingly important for the safe use, storage and transport of energy resources. Energy sources have been the target of increasing terrorism and wars since the 20th century. In the future, alternative energy sources, such as hydrogen energy, are expected to take the place of fossil energy resources. This means that ballistic threats will target these resources. In this study, for the first time in the literature, the ballistic behavior of Type 1 metallic pressurized hydrogen storage tanks made of the 6061 T6 aluminum and SS304 stainless steel alloys at the different thicknesses against 7.62 mm were investigated under usage pressure. For these alloys, the minimum safe wall thickness of the hydrogen tank is mathematically calculated using finite element analysis. © 2018 Hydrogen Energy Publications LLC

Consumption of the fossil fuels causes greenhouse gas effect and environmental pollution, which are two basic problems of our age. As a result of this problem, clean and renewable alternative energy sources are beginning to replace fossil fuels. Nowadays, the use of hydrogen energy, which is one of the clean energy, is increasing in transportation and industrial areas. Increasing of hydrogen energy usage, scientists are attempting to solve the many safety problems (such as fire, burst, impact and hydrogen embrittlement) that can occur during the storage and consumption of hydrogen energy. In this study, during the event of fire, the safety of metallic Type I pressure hydrogen storage tanks is investigated by using a novel approach. In this new approach, the mechanical strength drops of the tank materials that is related with temperature rising are added to the safety calculations. In the study, 6061 T6 aluminum and SS 316L stainless steel alloys were used as hydrogen tank material. The safety of hydrogen tanks modelled using these alloys was investigated under different temperature conditions (22, 100, 200 and 300 °C) and internal pressure (15, 20 and 25 MPa). © 2018 Hydrogen Energy Publications LLC

Purpose: This study examines the dyadic adjustment of married men and women with multiple sclerosis (MS). Method: This cross-sectional study consists of 40 patients with MS who were married and being followed in the neurology clinic of a university hospital. Data collection was performed by face-to-face interviews with only the participant and the researcher present. The participants filled in the Expanded Disability Status Scale, a sociodemographic form, and a dyadic adjustment scale. Results: The study group was 75% male, with age ranging from 27 to 65 years (mean, 44.40 ± 9.31 years). Expanded Disability Status Scale scores ranged from 0 to 7 (mean, 3.25 ± 1.94); 95% of the subjects were having relapses and remissions. Scores for patients with MS who were not considering divorce were statistically significantly higher than patients with MS who were considering divorce for dyadic adjustment (z = 3.845, P =.000), common view (z = 2.336, P =.020), endearment (z = 2.701, P =.007), and total scores (z = 3.399, P =.001). Conclusion: Most of the patients with MS who participated in this study were diagnosed with relapsing-remitting MS with a mean Expanded Disability Status Scale score of 3, indicating that patients had the physical ability to perform routine activities. The total dyadic adjustment scale score (107.7) is above average, indicating that dyadic adjustment was at a good level. © Copyright 2018 American Association of Neuroscience Nurses.

BACKGROUND: Repeated cigarette use in individuals generally occurs due to the craving for smoking. Orexin-leptin hormones and temperament character traits are thought to be important factors affecting nicotine craving.

In this study, the influence of the number of forging stages on the crack formation and forging forces in the hot-forging process for mining support clamps that were produced from 31Mn4 material was investigated. In this context, a single-stage process has been considered and a multiple-stage forging process that included a pre-forming stage was fictionalized with the aim of preventing crack formation by obtaining crack-formation zones. It is aimed to improve the toughness properties of the final product by ensuring that the material flow lines are obtained in accordance with the product geometry as well as preventing the formation of cracks by the forging process design, including the preforming step of the mining support clamp. Designed dies and workpieces were simulated using the finite-volume method. According to the simulation results of forging process, the stress and strain variation of materials is obtained as max. 229 MPa and 3.969 MPa. Damage analysis of the sample with effective stress and strain is exposed as 0.438-1.0 flash surface of material. The increase in the forming step decreased the forging forces per step and the crack formation was prevented and the material flowlines can be arranged in accordance with the product geometry in the presence of the preforming stage in the hot-forging process and that this regulation has a reducing effect on the forging forces. The material flowlines of the samples obtained from real production were examined and validation of the simulations and actual production was provided. © Institute of Metals and Technology, Ljubljana, Slovenia.

INTRODUCTION: Obsessive compulsive disorder (OCD) is a chronic disease that affects social relationships, and occupational and academic performance of patients and their relatives due to cognitive, emotional, and behavioural aspects of the disease. Quality of life (QoL) in relatives of patients with OCD has previously been reported and compared with caregivers of patients with other psychiatric conditions. However, there are few studies available in the literature regarding the causality of QoL in caregivers of patients with OCD. OBJECTIVE: The aim of this study was to evaluate QoL of caregivers of patients with OCD and predictors of QoL of the family caregivers. METHODS: The study population comprised of 68 patients with OCD and their caregivers. The dependent variable of this study is “QoL of caregivers” as assessed by the short version of the World Health Organization Quality of Life questionnaire (WHOQOL-BREF-TR). The Structured Clinical Interview for DSM-IV/Clinical Version (SCID-I/CV), Yale-Brown obsessive-compulsive scale (Y-BOCS), Y-BOCS symptom checklist, Hamilton Depression Rating Scale (HAM-D), and WHOQOL-BREF-TR were completed by the patients, whereas the SCID-I/CV, WHOQOL-BREF-TR, and Burden Assessment Scale (BAS) were completed by the caregivers. Student’s t-test, MWU, ANOVA, Kruskal–Wallis ANOVA, and Spearman’s correlations were used in univariate analyses, and multiple linear regression tests were run in multivariate analyses. Critical VIF values were taken as 5.0 for detecting collinearity among independent variables in the regression analyses. Type 1 error was taken as 0.05 in the analyses. RESULTS: Linear regression analysis showed that caregivers’ sex, education level, occupational status, disease burden, and patients’ sex, physical QoL, and disease severity were predictors of caregivers’ QoL. Moreover, disease burden was the only common predictor that affected all four dimensions (physical, psychological, social relations, environmental) of the caregiver’s QoL, and as the perceived disease burden increased, the caregiver’s QoL deteriorated. © 2018, © 2018 The Author(s).

The role of position of methyl substitution on the inhibitor character of the ligands was discussed on the basis of noncovalent interaction profiles. © 2018 Elsevier B.V.

A simple method was validated for the analysis of 31 phenolic compounds using liquid chromatography- electrospray tandem mass spectrometry. Proposed method was successfully applied to the determination of phenolic compounds in an olive leaf extract and 24 compounds were analyzed quantitatively. Olive biophenols were extracted from olive leaves by using microwave-assisted extraction with acceptable recovery values between 78.1 and 108.7%. Good linearities were obtained with correlation coefficients over 0.9916 from calibration curves of the phenolic compounds. The limits of quantifications were from 0.14 to 3.2 μgg-1. Intra-day and inter-day precision studies indicated that the proposed method was repeatable. As a result, it was confirmed that the proposed method was highly reliable for determination of the phenolic species in olive leaf extracts. © The Author(s) 2017.

Objective: To assess the effects of physical and depressive symptoms on the sexual life of women in the climacteric period. Methods: This study was conducted with 572 women at a university hospital. The Beck Depression Inventory (BDI), Menopause Rating Scale (MRS) and Female Sexual Function Index (FSFI) were used to evaluate depressive symptoms, intensity of menopausal symptoms and sexual function. Results: Sexual dysfunction and depressive symptoms were determined in 86.4% and 54.9% of the women, respectively. In univariate analysis, women without health insurance, with low income, being married for longer than 21 years and being in menopause had low FSFI but high BDI and MRS scores. In multiple regression analysis, advanced age of women, women with low income, unemployed women, low educated women and their husbands and women with depressive symptoms had low FSFI scores. There was a negative relationship between total FSFI and MRS and BDI scores.

Experimental studies in the aqueous solution are crucial for the detection of metal cations in environmental and biological media. Polymer materials allow to work in aqueous media for fluorescent substances which are insoluble in water. Fluorescence sensor studies of the phenanthroimidazole imine compound (PI) synthesized previously by our group were performed in the polymer medium and the selective response to Fe (III) cation was obtained. The resulting sensor exhibited a selective fluorescence quenching effect to Fe (III). A logarithmic calibration graph was obtained in the range of 5.0 × 10− 5 and 1.0 × 10− 2 M. The interference effects of other ions besides Fe (III) have been examined and it has been observed that PI compound behaves selectively to Fe (III) ion in aqueous media. In addition, regeneration and reproducibility studies were carried out to determine the long-term usage of PI doped polymer film and reproducible results have been obtained for Fe (III) cation. © 2017, Springer Science+Business Media, LLC, part of Springer Nature.
