Kucukosman, Rıdvan; Sukuroglu, Ebru Emine; Totik, Yasar; Sukuroglu, Suleyman
Graphene oxide (GO) integrated composite coatings were deposited on AZ91 magnesium alloys by the PEO (Plasma Electrolytic Oxidation) and the treatment which has a post-PEO hydrothermal process. For the first group samples, PEO was performed in the silicate/phosphate-based electrolyte including 5–10 µm in size the GO particles synthesized using the Tour Method. For the second group samples, after PEO treatment, the post-PEO hydrothermal process was carried out in the oven in the GO-distilled water mixture containing GO produced with the same protocol. The effects of GO on wear behavior, structural and morphological features of composite coatings were examined with a pin-on-disc tribometer, X-ray diffraction (XRD), scanning electron microscopy (SEM) and Raman spectroscopy, respectively. The results showed that the addition of GO improved significantly the adhesion to the substrate material of composite coatings, increased the coating thickness and hardness. Post-PEO hydrothermal process resulted in the formation of partial a thin solid lubricant GO film on the surface of composite coatings and thus exhibited the best wear and friction resistance.

Melek, Mesut; Manshouri, Negin; Kayikcioglu, Temel
Different biological signals are recorded in sleep labs during sleep for the diagnosis and treatment of human sleep problems. Classification of sleep stages with electroencephalography (EEG) is preferred to other biological signals due to its advantages such as providing clinical information, cost-effectiveness, comfort, and ease of use. The evaluation of EEG signals taken during sleep by clinicians is a tiring, time-consuming, and error-prone method. Therefore, it is clinically mandatory to determine sleep stages by using software-supported systems. Like all classification problems, the accuracy rate is used to compare the performance of studies in this domain, but this metric can be accurate when the number of observations is equal in classes. However, since there is not an equal number of observations in sleep stages, this metric is insufficient in the evaluation of such systems. For this purpose, in recent years, Cohen’s kappa coefficient and even the sensitivity of NREM1 have been used for comparing the performance of these systems. Still, none of them examine the system from all dimensions. Therefore, in this study, two new metrics based on the polygon area metric, called the normalized area of sensitivity polygon and normalized area of the general polygon, are proposed for the performance evaluation of sleep staging systems. In addition, a new sleep staging system is introduced using the applications offered by the MATLAB program. The existing systems discussed in the literature were examined with the proposed metrics, and the best systems were compared with the proposed sleep staging system. According to the results, the proposed system excels in comparison with the most advanced machine learning methods. The single-channel method introduced based on the proposed metrics can be used for robust and reliable sleep stage classification from all dimensions required for real-time applications.

Saydam Eker, Ç.; Sipahi, F.; Akpınar, I.
To investigate the impact of potential hazardous element (PHE) contamination on environmental and human health, the coaly shale, coal and shale coal outcrops of four sites, namely Ozyurt, Tarhanas, Kayadibi (Gümüşhane), and Manas (Bayburt), were selected as sampling areas for this study. The samples were analyzed using inductively coupled plasma (ICP) emission spectrometry and inductively coupled plasma-mass spectrometry (ICP-MS) and a Rock–Eval 6 analyzer with a total organic carbon module. The enrichment factor (EF), potential ecological risk index (RI), and potential health risk index (HI) assessment models were used to evaluate the environmental and health risks in the vicinity of the coals. Results indicated that the mean concentrations of PHEs extensively changed and even exceeded the upper continental crust and world average values of low-rank coal concentrations. The assessment of the EF, RI and HI models revealed that the contamination levels of As, Hg, and Cd were higher than those of Pb, Co, Ni, V, and Mo. The evaluation of the EF revealed that the largest and lowest contamination levels of As, Hg, and Cd were observed in Ozyurt (29) and Kayadibi (1.8), Manas (9.6) and Kayadibi (1), and Kayadibi (5.6) and Tarhanas (1.9), respectively. A high-potential ecological risk was present in Ozyurt and Manas, whereas a considerable risk exists in Kayadibi and Tarhanas. The potential health risk values of As for children in Ozyurt, Tarhanas, and Manas and adults in Ozyurt were excessively high. This finding suggested the possibility of transferring the contamination from the coal, shale coal, and coaly shale outcrops

- MakaleYalnız künye2021Scopus SJRQ2Optimization of ohmic heating assisted hydrodistillation of cinnamon and bay leaf essential oil
Tunç, Merve Tuğçe; Koca, İlkay
In this work, optimum ohmic heating assisted hydrodistillation (OAHD) conditions for extraction of cinnamon (CEO) and bay leaf (BEO) essential oil were determined by response surface methodology (RSM). OAHD were compared with conventional hydrodistillation (HD). Hydrodistillation time (30–120 min), mass of sample (20–40 g) and voltage gradient (7.5–12.5 V/cm), were varied to maximize essential oil (EO) yield and minimize energy consumption. Optimized OAHD conditions were determined as 119.90 min, 8.83 V/cm and 40 g, and 120 min, 8.53 V/cm and 40 g for CEO and BEO, respectively. EO yields of cinnamon and bay leaves at optimum conditions were found 3.98 ± 0.25% and 1.36 ± 0.14%, respectively. Energy consumptions were found 0.42 ± 0.02 and 0.86 ± 0.09 kWh/g EO for CEO and BEO, respectively. EO yield of OAHD was found to be higher when compared with HD methods for both plant materials. Energy consumptions and emitted CO2 values of OAHD method were significantly (p < 0.05) lower than HD methods. Cinnamaldehyde (CEO) and eucalyptol (BEO) contents of essential oils extracted with OAHD were higher when compared with HD methods. Antioxidant activities of essential oils extracted with different methods were not significantly different. CEO and BEO formed inhibition zones against all tested microorganism strains. Practical Applications: Essential oils of cinnamon bark and bay leaf are commonly used for food and pharmaceutical industries and, have important economic value. Conventional hydrodistillation method to extraction essential oils is time consuming, requires more energy and has more CO2 emission rates. Ohmic heating assisted hydrodistillation as a novel technology, is a promising method to extraction of essential oils from different plant materials with lower process times and energy consumption when compared with conventional hydrodistillation. Ohmic heating assisted hydrodistillation method can developed with regard to scale up as a green technology to essential oil production. This work provides a knowledge about the effects of different OAHD process variables on essential oil yield and energy consumption for cinnamon bark and bay leaf essential oils. It is expected that the outcomes of this study will be useful for the designing of large scale ohmic heating assisted hydrodistillation units.

Purpose: The purpose of this study is to evaluate and determine the gynecological cancer awareness among women aged 20 and over and make recommendations according to the current situation. Method: The study is a quantitative, descriptive, and cross-sectional study. The population of the study was composed of a total of 60.290 women aged over 20 years living in the city center of Gumushane according to TURKSTAT data for 2017. The sample consisted of a total of 382 women determined at 95% confidence interval. Personal information form and Gynecological Cancer Awareness Scale were used to collect the data. Results: The mean age of the women was 39.07 ± 17.84. 48.6% of the participants had knowledge about gynecological cancers, and only 16.2% reached this information from healthcare personnel. It was determined that the women who were working, had an employed husband, had a high level of education, had a husband with high level of education, had no chronic disease, and had knowledge about gynecologic cancers were higher than the others. The awareness of the participants about gynecological cancer decreased as their ages, body mass index, the number of pregnancy and birth increased. The gynecological cancer awareness of the women increased with the increase in marriage age, the age of first sexual intercourse, and the age of first pregnancy. Conclusion: Early diagnosis of gynecological cancers with effective and common screening programs is very important in reducing mortality and morbidity rates. It is recommended to maintain healthy lifestyle behaviors, avoid risky behaviors, screen risky groups and ensure women’s awareness for primary prevention.

Çelik, Orkun; Erer, Elif
We aim to explore the role of gender in the government expenditure and unemployment nexus at regional level for Turkey. For this aim, we use the dataset covering the period 2004-2019 for 26 NUTS-2 regions in Turkey and employ a panel ARDL approach. The obtained empirical findings show that government expenditure and gross domestic product per capita provide overall, female, and male unemployment rates to diminish in the long term, which means the Keynesian approach is valid on the long term. Nevertheless, on the short term, government expenditure induces rises in the male and female unemployment rates. This result indicates the validation of the Abrams Curve Hypotesis in male and female unemployment rates on the short term. Also, inflation rate increases overall and male unemployment rate on the long term, but having significant and positive impact on only female unemployment rate on the short term. All these findings show that gender has a significant role in this nexus. The expected contribution of this study to literature is to investigate the impact of government expenditure on unemployment by gender at regional level for Turkey. We are of opinion that our empirical findings can guide policy makers in active plans fighting unemployment.

Dağ, Serhat; Alemdağ, Selçuk; Kaya, Ayberk
The present study aims to examine the usability of the Gümüşhane Granitoid as a building stone taking into consideration the short-term freeze-thaw cycles and mean block volume. A total of 180 specimens were used in the study prepared from the block samples compiled from 10 different areas in the Gümüşhane (NE Turkey) provincial borders. Mean block volume was calculated about 8 dm3 during the discontinuity studies carried out on the Gümüşhane Granitoid; as a result of which, it was determined that the granitoids are suited for obtaining blocks. The annual freeze-thaw cycle map of Turkey was used for determining the number of freeze-thaw cycles to be applied on the rocks in addition to taking into account the weathering of monzogranites. A total of 25 freeze-thaw cycle tests were applied on the rocks with experimental studies repeated at every 5 cycles. It was determined following the freeze-thaw tests that significant changes have occurred especially in the strength and water absorption parameters of the monzogranites and that they have been affected negatively. This indicates that the monzogranites are not suited for outdoor use as building stone in regions such as the Gümüşhane province and regions with similar climate characteristics, but that they can be used in a lot of regions with more moderate climates. As a building stone, monzogranites can be used either as cobblestone, curbstone, or paving stone subject to their mean block volume. It is considered that the widespread of the Gümüşhane Granitoid may provide a substantial economical income to the country.

In the present paper, identification elliptic problem in a Hilbert space with Dirichlet and integral boundary conditions is discussed. Identification problem is reduced to auxiliary nonlocal boundary value problem with nonlocal integral condition. Operator approach is used to prove stability and coercive stability inequalities for solution of source identification elliptic problem in the case of a self-adjoint positive definite operator in a differential equation. As applications, four mixed boundary value problems for strongly elliptic multidimensional partial differential equation are investigated. Theorems on stability of solutions of these boundary value problems are established.

In this study, the effects of GSM 1800 band radiation on composition, structure and bioactivity of exopolysaccharides (EPSs) produced by Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus were determined. For this, GSM 1800 band radiation was applied to both cultures and characteristics of EPSs extracted from the control groups (K) and the radiation stressed groups (R) were determined. An alteration in the chemical composition of the EPSs was observed and EPS production levels and molecular weights of the EPSs increased following the GSM 1800 band radiation application. Alterations in the functional groups, thermal and morphological characteristics of EPSs following the GSM 1800 band radiation application were confirmed by FTIR, TGA and SEM analysis, respectively. Importantly no alterations in the antioxidant and antibacterial activity of the EPSs were observed following the radiation application. These results suggested the effects of the GSM radiation on final characteristics of EPSs from yogurt starter cultures.

Erol, Ismail; Peker, Iskender; Ar, Ilker Murat; Turan, İsmet; Searcy, Cory
Novel business models can be implemented through digital platforms to enable better circular economy (CE) performance in the renewable energy industry. For example, blockchain can assist in developing innovative business models throughout the solar photovoltaic energy ecosystem (SPVEE) to improve CE. Ranked fifth in total installed photovoltaic (PV) capacity, Turkey, as a developing country, should take the necessary steps and make progress towards achieving CE in the SPVEE. The solar PV industry requires further innovation to address the negative environmental impact of existing linear business models. To ensure favorable results, identifying and evaluating critical success factors (CSFs) are necessary. However, no study has investigated CSFs for SPVEE or any other renewable energy source to achieve a blockchain-based infrastructure towards increased CE performance. Therefore, the goal of this study is to identify and examine the CSFs to improve the performance of a blockchain-based SPVEE towards CE in Turkey. To this end, first, the CSFs for blockchain-based SPVEE were identified through both a literature review and the Nominal Group Technique (NGT). Then, Intuitionistic Fuzzy (IF)-DEMATEL was used to explore their interrelationships based on the expert data. Finally, IF-DELPHI was employed to validate the results. Our findings suggested that effective government incentive programs and regulations are significant for blockchain-based SPVEE towards CE in Turkey. The findings of this study assist macro and micro decision-making in the potential implementation of blockchain in Turkish SPVEE to improve CE. They are also invaluable for other countries and can be used as a reference point.
AtıfScopus60WoS51OpenAlex58İncele - Kitap BölümüYalnız künye2021XIV: Is chivalric love the true love?
Yalçin, Elif Güvendi; Üçele, Hatice Gönül
Romances dates back to the creation of stories. In English history, the romance genre has evolved from the middle aged chivalric romances in between 14th and 15th centuries, to Elizabethan romances in the 16th century, to Gothic romances in the 18th century and the romances of the 19th century. Anthony Giddens's theory of "The Transformation of Intimacy" proposes that romantic love which he sees as the outcome of modernization of Western societies emerges in the late 18th century onwards and is linked with romance as a literature genre. Giddens starts with the appearance of romantic love which is a paragon that is extensively distributed in the 19th century, when marriage starts to get rid of the monetary and kinship ties which have the utmost importance in pre modern societies. In this concept, love which is inconsistent with intimacy and sexuality in pre modern societies is transformed into a confluent love in modern societies with the appearance of more independent and emancipated individuals. The aim of this study is to demonstrate the idea of courtly love within the concepts of gender, sexuality, marriage and rape. Therefore, this paper examines the classic work of Sir Walter Scott's Ivanhoe (1820). Ivanhoe (1820) is accepted as the classics of both English language- literature and Scottish literature. Although Ivanhoe is not accepted as 'non serious' popular romance novel, it employs the traditional development of the romance story line, which can be summarized as the struggle between good and evil represented in the main male figure and villains, the dangerous journey of the chief character, his specific battle and journey through ritual death as well as his saving the unprotected lady and wedding at the end. The story is set in medieval times and the issue of medievalism is inseparable from the characters' appreciation of love. At that time, there is no place for bodily desires and passion. Thus, the identities of female and male, love- marriage relationships, and the issue of rape reflect the early 19th century ideals which promote the values of chivalry.

Superconducting specimens of Y3-xLuxBa5Cu8O18+δ (where x = 0, 0.2, 0.4, 0.5) ceramic were fabricated via the solid-state route (SSR). The structural and superconducting features of the specimens were analyzed using X-ray diffraction (XRD) and scanning electron microscopy (SEM). Measurements and calculations were carried out for electrical resistance (R-T) and DC magnetization (M-H). The onset critical transition temperature (Tconset) of the specimens dropped to lower temperatures with the addition of lutetium (Lu). The estimated critical current density (Jc) values of the specimens, depending on the magnetic field, were extracted from the DC magnetization data. The changes in average grain size and bulk critical current density were examined. Improvement was observed in the bulk critical current density with increasing levels of Lu/Y substitution.

Study Objectives: This study aimed to determine whether the Kinesio tape (KT) application through reverse taping on the quadriceps (Q) and hamstring (H) muscles have any effect on anaerobic power (AP). Methods: Sixteen healthy males were included in the study voluntarily. Muscle facilitation and muscle inhibition techniques were performed on the Q and H muscles of both the right and left sides by applying KT in the reverse direction, and AP parameters were measured using a Wingate ergometer. In trial 1 (Baseline), KT was not applied to the participants. In trial 2 (KT), the muscle facilitation technique was applied on the vastus medialis muscle in the Q of both legs, and the muscle inhibition technique was applied on the biceps femoris and semimembranosus muscles in the H, and AP performances of the participants were taken. The SPSS 22.0 software was used for statistical analysis. Paired sample t-test was used to analyze the differences between trials. Results: KT gave higher values than Baseline with regards to peak power, relative peak power, average power, and relative average power (p < 0.05). In addition, as a result of the KT application, there were minor improvements in minimum power, relative minimum peak power, power drop, and peak power %. However, these differences were not statistically significant (p > 0.05). Conclusions: It was observed that KT applied in the reverse direction on the Q and H muscle groups had a positive effect on AP. It was considered that this effect associated with the reverse KT application stemmed from the different tensions that decreased the neuronal threshold, which in turn ensured faster and easier stimulation of motor units and increased the muscle reflex, leading to a positive effect on AP.

Kahraman, Muhammet Mustafa
Despite technological advancements and organizational adjustments, lost time accidents are major issues in occupational safety. However, there is very limited work that focuses on variables influencing days lost as a result of occupational accidents. In this study, decision tree and artificial neural network methods were used as machine learning techniques to investigate the impact of factors on accident lost day duration. Degree of injury, worker age, and worker activity were found to be the top three variables impacting loss of time from work. It was also identified that the mining method, location, and nature of injury had a moderate influence on duration lost due to occupational accidents. However, worker experience and ore type did not have any significant impact on the duration, which is an unexpected result. These results confirmed that some accident factors that might have a large influence on the number of mine accidents can be less critical when it comes to accident lost day duration.

Karsli, Orhan; İlhan, Mehdi; Kandemir, Raif; Dokuz, Abdurrahman; Aydin, Faruk; Uysal, İbrahim; Duygu, Levent
Late Mesozoic evolution of the Neotethys Ocean is critical and still remains unclear along the entire Sakarya Zone (SZ), Turkey, because previous interpretations of the Middle to Late Jurassic rifting of the SZ have not been consensually accepted. We identified, for the first time, the Early Cretaceous dykes intruded into the Late Jurassic and Late Carboniferous bodies in the Çamlıkaya (Erzurum) area in the SZ. Here, we present a data set of new field observations, 40Ar/39Ar geochronology, whole-rock geochemical and Sr–Nd isotopes to find out the tectonic setting of previously undated basic to intermediate igneous rocks. 40Ar/39Ar technique on the groundmass separations yielded the plateau ages of 128.78 ± 1.02 to 122.89 ± 0.82 Ma. The investigated dykes are compositionally divided into two sub-groups: calc-alkaline lamprophyres (CAL) and high-Nb alkaline basalts (HNB). They show enrichment in large ion lithophile elements (LILE: e.g., Rb, Ba, K) and depletion in high field strength elements (HFSE: Nb and Ti) as well as moderate fractionation of light rare earth elements relative to heavy rare earth elements. The HNB have high Mg# (47–66), and relatively unradiogenic Sr [87Sr/86Sr(t) = 0.70385 to 0.70510] and Nd [εNd(t) = +0.5 to +5.3] isotopic composition, whereas the CAL possess moderate to high Mg# (32–72), and relatively high Sr [87Sr/86Sr(t) = 0.70586 to 0.71379] and Nd [εNd(t) = +1.5 to −9.9] isotopic composition. Early Cretaceous high-angle subduction triggered upwelling of the asthenosphere at 126 Ma, which likely generated a heat anomaly. This anomaly has probably induced melting of the oceanic slab and the metasomatized mantle to form the CAL and HNB. The HNB were generated by low degrees of melting of mantle domain that was previously reacted by oceanic slab-related adakitic melts at the depths of the garnet stability field (≥70 km). However, the CAL were probably formed at shallower mantle levels within the garnet-amphibole field by a relatively higher degree of melting of the mantle, also modified by subducted slab sediments. A new field, age, and petrochemical data from the Early Cretaceous dykes, combined with the presence of Aptian deep-water sediments to the north and the Late Jurassic-Early Cretaceous platform carbonates deposited in the passive margin setting along the entire SZ, imply the initiation of active-margin magmatism in the SZ. We suggest that the coexistence of the Early Cretaceous CAL and HNB points to the formation of an Andean-type active margin above a north-dipping Neotethyan oceanic slab. Their emplacement ages are associated with the inception of the magmatic arc structure and refer to a significant geodynamic turnover from passive-margin to active-margin tectonics along the SZ.

The authors wish to inform that the correct abstract for the article is given below: Objective: Pain is one of the most common symptoms and may lead to important psychological, mental, and physiological problems in individuals. According to data by The Center for Reiki Research, Reiki is an effective approach to decrease the levels of pain, depression, and anxiety. Therefore, the aim of this meta-analysis was to investigate the effect of Reiki on pain level. Methods: Randomized controlled clinical trials in databases of Pubmed, ISI Web of Sciences, and Google Scholar were investigated. Four randomized controlled studies which involving 212 participants were included in the meta-analysis. Results: The result obtained after the final Reiki application was evaluated in VAS pain score. When Reiki (n = 104) group was compared with control group (n = 108), standardized mean difference was observed to be −0.927 (95% CI: −1.867 to 0.0124). Conclusion: Consequently, meta-analysis shows there is a trend towards lower pain scores after Reiki intervention. It is recommended to repeat the study when the number of studies with specific patient groups and types of pain increase. The authors would like to apologise for any inconvenience caused.
