- MakaleAçık Erişim2024Scopus SJRQ2Identification of magnetic mineralogy and paleo-flow direction of the Miocene-quaternary volcanic products in the north of Lake Van, Eastern Turkey
Kayln, Sercan; Işseven, Turgay
One of the major challenges facing geochemistry, petrology, and volcanology researchers is the difficulty in determining the origin and paleo-flow directions of igneous and volcanic rocks. It is not possible to clearly determine origins and paleo-flow directions in areas with numerous volcanic centers. Anisotropy of magnetic susceptibility (AMS) is a valuable method that provides insights into the origins and paleo-flow directions of lavas that are complex to study. The presence of volcanic materials with thicknesses up to 1 km, coming from different sources at varied time intervals in the north of Lake Van, makes this area an ideal setting for implementing AMS in establishing paleo-flow directions. This study presents the magnetic mineralogy and AMS analysis of volcanic rocks from the Miocene to the Quaternary in the Lake Van region. We conducted isothermal remanent magnetization (IRM) and high-temperature susceptibility (HTS) studies to determine the magnetic mineralogy. IRM studies revealed that (titano)magnetite is responsible for the magnetization in most samples, while both (titano)magnetite and hematite are responsible for the rest. Alteration degrees and Curie temperatures of the rock samples were also determined through HTS measurements. There is good agreement between the anticipated directions of lava flow and our findings for nearly all volcanic rocks.

Muslu, Ayşe; Üçüncü, Osman; Baltacı, Cemalettin
The compound 5-(hydroxymethyl)furfural (HMF) has emerged as a versatile intermediate with the ability to undergo conversion into both fuel and a variety of platform chemicals. Lignocellulosic biomass, such as hazelnut shells and tea processing residues, was employed in this study for HMF production through two distinct methods. In the first method, cellulose from biomass was converted to sugars using a 4% acid solution, followed by catalytic conversion with NaCl/CrCl3.6H2O. After a 1-h reaction at 131 °C in a high-pressure system, HMF was obtained from tea processing waste and hazelnut shells with yields of 8.6% (82.3 mg/g) and 6.7% (66.7 mg/g), respectively. The second method involved LiCl/NaCl-doped N,N-dimethylacetamide (DMA) as an ionic solvent system for HMF production. After a 2-h reaction at 131 °C in the DMA-NaCl/[EMIM]Cl ionic solvent system, HMF was obtained from tea processing waste and hazelnut shell celluloses with yields of 5.7% (57.5 mg/g) and 3.1% (31.3 mg/g), respectively. This study contributes to the economic conversion of various food wastes into valuable chemicals, highlighting the potential of lignocellulosic biomass in sustainable chemical production.

Ulutaşdemir, Nilgün; Ay, Halil; Göçmen, Adalet; Uzun, Sevda; Kulakaç, Nurşen
OBJECTIVE: To determine the practices and coping experiences of the relatives of patients with pressure injuries (PIs). METHODS: The authors used a qualitative, phenomenologic research design. They interviewed 20 relatives of patients with PIs face-to-face using an in-depth semistructured interview form. The data were analyzed using the Colaizzi phenomenologic method. RESULTS: Three categories, 8 main themes, and 22 subthemes emerged from the interviews. The category of “the impact of the need for care on the lives of the patient’s relatives” was analyzed according to psychological, social, and physical effects. In the category of “practices to prevent pressure injuries,” two themes emerged: practices toward the patient and the environment. Relatives of individuals with PIs have psychological, physical, and social needs. CONCLUSIONS: Providing care to a patient with PIs has psychological, social, and physical effects on the patient’s relatives. The care burden mostly affects these caregivers negatively, and they mainly need time for themselves and moral and companion support.

This paper presents a sentiment analysis combining the lexicon-based and machine learning (ML)-based approaches in Turkish to investigate the public mood for the prediction of stock market behavior in BIST30, Borsa Istanbul. Our main motivation behind this study is to apply sentiment analysis to financial-related tweets in Turkish. We import 17189 tweets posted as "#Borsaistanbul, #Bist, #Bist30, #Bist100″ on Twitter between November 7, 2022, and November 15, 2022, via a MAXQDA 2020, a qualitative data analysis program. For the lexicon-based side, we use a multilingual sentiment offered by the Orange program to label the polarities of the 17189 samples as positive, negative, and neutral labels. Neutral labels are discarded for the machine learning experiments. For the machine learning side, we select 9076 data as positive and negative to implement the classification problem with six different supervised machine learning classifiers conducted in Python 3.6 with the sklearn library. In experiments, 80 % of the selected data is used for the training phase and the rest is used for the testing and validation phase. Results of the experiments show that the Support Vector Machine and Multilayer Perceptron classifier perform better than other classifiers with 0.89 and 0.88 accuracy and AUC values of 0.8729 and 0.8647 respectively. Other classifiers obtain approximately a 78,5 % accuracy rate. It is possible to increase sentiment analysis accuracy with parameter optimization on a larger, cleaner, and more balanced dataset by changing the pre-processing steps. This work can be expanded in the future to develop better sentiment analysis using deep learning approaches.

The Late Cretaceous magmatic history of the Eastern Pontides Orogenic Belt (NE Turkey) was generally characterized by common I-type and lesser A-type plutons in varying size and composition. Of these, A-type plutons from the Şebinkarahisar (Giresun) area yield SHRIMP zircon U-Pb age of 77.36 ± 0.96 Ma. The rocks of these plutons display a wide range of SiO2 contents (53.63 to 70.96 wt.%) and Mg-numbers (6.2–32.19) with A-type affinities characterized by enrichment in K2O and Na2O, Ga, Zr, and strong negative Eu anomalies. They also show arc-type petrochemical features including enrichment of large-ion lithophile elements (e.g. Cs, K, Rb) and light rare earth elements (LaN/LuN = 6.27–15.61), but depletion in high strength field elements (e.g. Nb, Ta, Ti, and P). The (87Sr/86Sr)i ratios and ɛNd(i) values of the studied rocks are in the range of 0.705129 to 0.0705347 and −3.64 to −3.12, respectively, while bulk rock ɛHf(i) values are between 1.86 and 4.36. They are characterized by positive zircon ɛHf(i) (1.74 to 10.88) plotting between the chondrite and depleted mantle evolutionary line values. Our data combined with the previous studies suggest that the magmas, that formed the Late Cretaceous plutons, were generated in an extensional tectonic environment due to slap roll-back and trench ward migration of the subduction zone to the south. The generation of hybrid magmas forming the studied plutons is in response to the melts derived from a metasomatized lithospheric mantle source, a relatively deeper mantle source, and the juvenile crust along with the heat transfer and decompression. Multi-sourced magmas rise through the continental crust and reach the final composition by predominantly fractional crystallization processes.

The sexual abuse of the child is a wide-ranging and complex problem with physical, emotional and psychological consequences, with social, moral, cultural and legal dimensions, and when the prevalence rates are analyzed, it is seen that it is a serious problem for all societies. One of the most common strategies used to prevent child sexual abuse is school-based initiatives. So, the purpose of this integrative literature review is to systematically evaluate the evidence of the effectiveness of school-based child sexual abuse prevention programs. In this context, the current study includes 22 articles that meet the criteria for inclusion. The Comprehensive Meta-Analysis (CMA) statistical program was used to calculate the effect sizes of the studies included in the meta-analysis. The mean, standard deviation, sample size, p, t, or f value data reported in the primary studies were used to calculate the effect sizes of the studies included in the meta-analysis. As a result of the analyzes carried out within the scope of the study, it was concluded that school-based education practices aimed at preventing child sexual abuse are highly effective, and that after the prevention programs, the knowledge and skill levels of the children increased widely and these increases were statistically significant. As a result, it can be said that the knowledge and self-protection skills of children can be increased by participating in school-based sexual abuse prevention programs.

This study aimed to examine the disease burden encountered by individuals with COPD, with a comprehensive investigation of the effect of the disease on sexual life. In this study, a phenomenological research design, a qualitative research type, was employed. The study involved 36 individuals diagnosed with COPD. The data collection process involved conducting individual, face-to-face interviews. Colaizzi’s phenomenological analysis method was utilized for the data analysis. The analysis of the data yielded two categories (burdens of the disease and sexual life) and six primary themes (physical effects, mental effects, social effects, difficulties during sexual activity, the spouse’s perspective on the problems, and dealing with sexual problems). The outcomes of this study highlighted the significant burden of COPD on patients and its adverse impact on their sexual lives. Given the complex nature of COPD, a thorough and professional assessment of patients’ sexual well-being, coupled with timely identification of sexual dysfunctions and appropriate interventions, is of utmost importance.

The aroma of fermented dairy products is greatly influenced by starter cultures and by the lactic acid bacteria strains that are used as starter cultures. Experimental butter samples were produced using no starter culture, by a commercial starter culture (Lactococcus lactis subsp. lactis, Lactococcus lactis subsp. cremoris, Lactococcus lactis subsp. lactis biovar. diacetylactis, Leuconostoc mesenteroides), by a prepared bacteria mix (Lactococcus lactis subsp. lactis EM1, Lactococcus lactis subsp. cremoris EM28, Lactococcus lactis subsp. lactis biovar. diacetylactis G49, Leuconostoc mesenteroides B3), and by a prepared bacteria mix fortified with Lactobacillus rhamnosus B19 (L. rhamnosus B19). The aroma profile of the butter samples was investigated using a gas chromatography mass spectometry method (GC-MS). A total of 92 components were determined in the butter samples, including acids (12), alcohols (20), aldehydes (9), alkanes (6), esters (8), ketones (19) and several other aroma compounds (18). The sample containing the prepared starter culture had the most detectable aroma components, while the lowest number of aromatic components were found in the sample without a starter culture. 2,3-butanedione (diacetyl) was not detected in the sample without a starter culture. 2-Butanone 3-hydroxy-(acetoin) content was the highest in the sample containing the commercial starter culture and the lowest in the sample without a starter culture.

Çelik, Kemal
Expropriation is widely used to introduce highway projects into the society. Expropriation is the registration process of real estate and equities owned by natural and legal persons on behalf of the administration for public interest, provided that property and easement right amount shall be paid in cash or in advance or by equal installments. In what situations and by which institutions expropriation is carried out are restricted by the law. In accordance with the Article 3 of the Expropriation Law Number 2942 amended by the Law Number 4650, the expropriation process shall not be started without an adequate allowance provided by the administration. The exercise of the right of property shall not be against public interest.” Project areas are required to be converted into public property after the development plans for the public projects are prepared. Areas regarded as private property but intersected by highway, railway or waterway routes can only be occupied after expropriation. Without expropriation, projects based on transportation in improvement areas can be opened to public with the application of the provisions of the Development Law Number 3194, while those in areas having no development plan can be opened to public with the application of the relevant provisions of the Agricultural Reform Law Number 3083 on Land Consolidation in Irrigated Areas and Law Number 5403 on Soil Conservation and Land Use. In this article, opening highways, railways, and waterways to public in Türkiye using the implementation of development plans is discussed. For the real estate coinciding with the route of public investments, if land and land lots are arranged in accordance with the Article 18 of the Development Law Number 3194, state withholding up to 45% may be imposed. The objective function in the state withholding can be stated as f= costmin= f(a,b). Land acquisition increases as the ratio of state withholding increases, resulting in the minimization of the expropriation costs. Public projects such as highway can be opened to public free of charge with development plan implementation in improvement areas and with land consolidation in rural areas having no development plan.

This study explores, the impacts of incorporating of deep eutectic solvent (DES) as plasticizer on the characteristics of zein films. Investigation focused on examining the mechanical, thermal, surface, and microstructural properties of zein films that were plasticized using DES. The findings of the study revealed that by adding DES to zein films, there was an observed improvement in transparency. Additionally, it was observed that up to a 20% addition of DES led to a reduction in water vapor permeability (WVP). However, beyond this level, the WVP increased as the surface hydrophobicity decreased. The films that were plasticized with DES showed higher tensile and burst strength values than control. However, there was a decrease in the elongation at break and burst distance, except for the film containing 30% DES. The addition of DES as plasticizer resulted in smoother surface morphology compared to the control, and all films revealed homogeneous and non-porous surface and cross-section microstructure. The films plasticized with DES displayed three different thermal degradation temperatures resulting in higher thermal stability. The FT-IR spectrum of films showed similar backbone structure including Amide I, II and III bands. However, 5% DES plasticized film showed different secondary structural peaks of Amide I band due to lower α-helix and higher β-sheet and random coil content. The findings of this investigation indicate that the employment of DES as plasticizer in biodegradable polymer films can yield enhanced mechanical and barrier characteristics compared to conventional plasticizers, thus demonstrating its potential for effective use.

SUMMARY OBJECTIVE: This study aims to examine the relationship between body image and the level of sexual satisfaction in women who have undergone a hysterectomy. METHODS: This descriptive study utilized a relational screening model. Conducted between June 2023 and March 2024, the study included a total of 300 sexually active women who had undergone a hysterectomy 6 months prior. Data were collected using a personal information form, the Golombok-Rust Sexual Satisfaction Scale, and the Body Image Scale through face-to-face interviews lasting approximately 20–30 min. RESULTS: The average age of the participating women was 44.4±10.55 years. Of the participants, 96.7% were married and 42.4% had entered menopause. The average score on the Body Image Scale was 81.2±3.8, and the average score on the Golombok-Rust Sexual Satisfaction Scale was 33.0±15.1. A positive significant relationship was found between body image and sexual satisfaction (p<0.05). There was also a statistically significant positive relationship between the total scores on the Body Image Scale and the Golombok-Rust Sexual Satisfaction Scale with age and frequency of sexual intercourse (p=0.049, p<0.001, p<0.001, p=0.047, and p=0.014). It was determined that as the age and frequency of sexual intercourse increased, the levels of body image and sexual satisfaction also increased. CONCLUSION: Our study found that women’s self-image is negatively affected, and their level of sexual satisfaction decreases following a hysterectomy.

The purpose of this study is to investigate the impact of different durations of Swedish massage on the static and dynamic balance at different times of the day in taekwondo athletes. Twelve taekwondo athletes who had been practicing on a regular basis for more than 5 years participated in this study. Taekwondo athletes completed static and dynamic balance tests either after a no-massage protocol (NMP), a five-minute massage protocol (5MMP), a ten-minute massage protocol (10MMP), or a fifteen-minute massage protocol (15MMP) two times a day in the morning (08:00–12:00) and in the evening (16:00–20:00), on non-consecutive days. The findings of this study suggest that the duration of the massage has a discernible impact on dynamic balance, particularly with regard to the right foot. Taekwondo athletes who received a 10MMP or 15MMP displayed significantly improved dynamic balance compared to those in the NMP. Importantly, these improvements were independent of the time of day when the massages were administered. It underscores the potential benefits of incorporating short-duration Swedish massages into taekwondo athletes’ pre-competition routines to enhance dynamic balance. These findings highlight the potential benefits of incorporating short-duration Swedish massages into taekwondo athletes’ pre-competition routines to enhance dynamic balance, a critical component of their performance, regardless of the time of day.

Nacar, Sinan; Şan, Murat; Kankal, Murat; Okkan, Umut
This study compares projected and past seasonal precipitation trends in the Eastern Black Sea Basin, Turkey. Historical data from twelve stations representing the basin during 1981–2010 was used, while statistically downscaled data from two representative concentration pathway scenarios (RCP4.5 and RCP8.5) outputs of the GFDL-ESM2M general circulation model were utilized for 2021–2050. To determine the seasonal trend behaviors of precipitation variables and transitions between consecutive months, the Innovative Polygon Trend Analysis (IPTA) was implemented. Furthermore, the star concept was employed to illustrate the changing sizes between consecutive periods. Both scenarios showed considerable summer and autumn declines at almost all locations, with low seasonal precipitation variability. These scenarios indicated January to be the important month for trend shift, except for Rize, Pazar, and Hopa stations. The formation of several polygons, polygons intersecting, and polygons not forming on the global regression line show that the hydro-climatic cycle might be chaotic.

The aim of this study is to determine the potential toxic element (PTE) content linked to the geochemical features of Berriasian–Aptian carbonate rocks commonly outcropping in Gümüşhane, along with the degree of pollution and possible sources of these toxic elements, and to compare dolomite with limestone in terms of toxic metal abundance. In the field, dolomite and limestone samples were collected by measuring stratigraphic sections around Yuvacık, Ünlüpınar, Çukutbaşı, Bağlarbaşı, Mescitli and Gülaçar (Gümüşhane). The samples were analyzed using inductively coupled plasma mass spectroscopy (ICP-MS). The mean values for Mo, Cu, Pb, Zn, Ni, As, and Co were 3.1, 23.8, 7.1, 14.5, 13.5, 30.9, and 8 mg/kg in Yuvacık; 6, 2.3, 1.1, 3.5, 8.1, 12.3 and 2.5 mg/kg in Ünlüpınar; 17.9, 1.8, 1.5, 8.6, 7.9, 13.9 and 1.7 mg/kg in Çukutbaşı; 3.7, 6.5, 31.7, 82.7, 9.5, 32.0 and 1.9 mg/kg in Bağlarbaşı; 0.7, 0.7, 7.1, 21.3, 2.6, 11.8 and 0.7 mg/kg in Mescitli; and 1.2, 1.1, 2.4, 5.2, 1.3, 4.0 and 0.2 mg/kg in Gülaçar, respectively. According to geochemical pollution parameters [geo-accumulation (Igeo), pollution index (Pi), and pollution load index (Pln)], the rocks were generally significantly polluted by Mo and As, without notable pollution by the other elements. Limestone samples from the Yuvacık, Ünlüpınar, and Çukutbaşı areas were more polluted in terms of Mo and As compared to dolomites. This pollution in Yuvacık and Ünlüpınar was identified to have geogenic sources (Pb–Zn–Cu mineralization) and in Çukutbaşı was identified to have lithogenic sources. Dolomites from the Bağlarbaşı area were more polluted in terms of As and less polluted in terms of Mo compared to limestones. In the Mescitli location, both dolomites and limestones were occasionally polluted in terms of As, while limestones were polluted in terms of Mo. In these two areas, the sources of As and Mo are geogenic (Pb–Zn mineralization), In Gülaçar, dolomites were more polluted in terms of Mo and less polluted in terms of As compared to limestones. In this locality, As and Mo are thought to have a geogenic source (Pb–Zn–Cu mineralization).

Alkan, Aslı; Anaç, Halil
In this research, we propose a new numerical method that combines with the Caputo-Fabrizio Elzaki transform and the q-homotopy analysis transform method. This work aims to analyze the Caputo-Fabrizio fractional Newell-Whitehead-Segel (NWS) equation utilizing the Caputo-Fabrizio q-Elzaki homotopy analysis transform method. The Newell-Whitehead-Segel equation is a partial differential equation employed for modeling the dynamics of reaction-diffusion systems, specifically in the realm of pattern generation in biological and chemical systems. A convergence analysis of the proposed method was performed. Two-dimensional and three-dimensional graphs of the solutions have been drawn with the Maple software. It is seen that the resulting proposed method is more powerful and effective than the Aboodh transform homotopy perturbation method and conformable Laplace decomposition method in the results.

Şahin, Mehmet Kürşat; Kurnaz, Muammer
The genus Lacerta, particularly the green lizard (Lacerta viridis), is a significant lizard group in the Western Palearctic. This study aims to predict its geographic range in Northern Türkiye and identify key habitat types based on the CORINE Land Cover classification. Occurrence records, gathered from published sources and on-site investigations, were analyzed using a 30 arc-second resolution layer and bioclimatic parameters from WorldClim v.2.1. The distribution was modeled in kuenm, and habitat use was assessed with generalized linear models. Results show that the green lizard’s occurrence is strongly influenced by precipitation dynamics and it prefers areas with little to no shade. These findings highlight the importance of precipitation in determining the species’ distribution and suggest further research on local dynamics for effective conservation.
