- MakaleAçık Erişim2022The relationship between perceived social support during pregnancy and postpartum comfort
Dal, Nursel Alp; Yetişmiş, Habibe Yaşar
This study was carried out to examine the relationship between perceived social support during pregnancy and postpartum comfort. The data for the cross-sectional study were collected from 544 puerperal women through face-to-face interview between 15.11.2019 and 15.03.2020, using a personal introduction form containing individual information, the Multidimensional Perceived Social Support Scale (MSPSS), and the Postpartum Comfort Questionnaire (PPCQ). Pearson correlation analysis and simple linear regression analysis were used together with descriptive statistics for statistical analysis. Results: 37.5% of the puerperal participants in the study were over 30 years old and 52% had more than three pregnancies. In our study, it was found that there was a positive significant correlation between the total MSPSAS and PPCQ total scores of the puerperal women (r = 0.140). As a result of the study, it was found that as the level of social support perceived by the puerperant during pregnancy increased, the postpartum comfort level increased. Midwives, who are an important part of social support, should determine the support level of pregnant women during pregnancy and birth, postpartum period, and provide support and information to women on all kinds of issues that will increase the comfort of women, such as education and counseling.

Danismaz, Harun; Köroglu, Kemalettin
Solhan Kalesi [Solhan Fortress] lies at the western tip of the Solhan Plain from which it derives its name. The fortress site was discovered in 2019 during surveys. Drywall fortifications reinforced with bastions and foundations from various buildings inside the fortification walls have been documented at the site. Ceramics and slag found at Solhan Fortress indicate that the site may have been a tribal center in the Iron Age. However, the architectural features of the fortress, especially the fortifications with bastions, are notably different from other Iron Age sites in the region. Surface finds do not include painted or glazed ceramics from the Medieval Period. Current findings indicate Solhan Fortress to have been inhabited for a long period from the Middle Iron Age to the Medieval Period.

Baskutlu, Salih
This article explores flour milling in the Ottoman State from traditional grinding techniques to modern grinding technologies. Although it investigates the historical progress of flour milling in general, the study aims to draw attention to the technological transformation in the milling industry. This scope focuses on the milling types used in the Ottoman world during the premodern periods. Secondly, it uncovers its milling activities and tax policies. Then, the article examines the emergence, development, operating systems, and legal structure of steam mills concerning industrialization efforts. To this end, it studies the competition between traditional mills and steam mills, its causes, and its effects on society. The study presents drawings of the mill models based on the documents found in Ottoman State Archives and to other sources. Grinding the grains with vital importance and serving them to public consumption was one of the primary concerns of the Ottoman State. For this reason, they operated water, wind, and muscle-powered mills for a long time. The emergence of industrialization brought about steam mills with high production capacity. The Ottomans, accordingly, followed the developments carefully to provide the citizens with healthier and hygienic flour with new production models.

This paper is mainly developed around the diagonal section which is strongly related to tail dependence coefficients as defined in Nelsen [19]. Hence, we propose a flexible method for estimating tail dependence coefficients based on the new smooth estimation of the diagonal section based on the Bernstein polynomial approximation. To assess the performance of the new estimators we conduct the Monte-Carlo simulation study. As a result of the simulation study, both estimators perform satisfactory performance. Also, the estimation methods are illustrated by real data examples.

In this study, the anatomical and micromorphological structure, karyological characteristics and biochemical content of Scutellaria orientalis subsp. virens and endemic Scutellaria salviifolia, whose distributions areas overlap, were compared. Some anatomical and micromorphological differences were observed on the taxa; scleranchymatic pericycle layer on the stem, stomata density, distribution of trichomes, as well as the main vascular bundle and general shape of the petiole. The chromosome numbers of both taxa were determined as 2n = 22. However, there was a difference between chromosome length range and total chromosome length. The chromosome numbers and chromosome morphologies of these species have been defined for the first time in this paper. Differences in biochemical content were observed between species. Chlorophyll a (Chl a), total chlorophyll (Total Chl), total carbohydrate and malondialdehyde (MDA) contents were determined higher in leaf and stem samples of S. orientalis subsp. virens than S. salviifolia. There was no significant difference between the two taxa in terms of chlorophyll b (Chl b) content. Carotenoid (Car) content was detected higher in leaves samples of S. orientalis subsp. virens, but no significant difference was found between stems samples. Also, the effect of taxa on biochemical contents in relation to the habitat they live in is given in this study.

In this study, ameliorative effects of ellagic acid (EA) on oxidative stress induced by chlorpyrifos (CPF) in carp, Cyprinus carpio, were investigated. Fish were divided into six groups: C (no treatment), EA (100 mg kg fish−1), CPF-1 (0.040 mg L−1), CPF-2 (0.080 mg L−1), CPF-1 + EA, and CPF-2 + EA. CPF and EA were applied simultaneously for 14 days and, at the end of the study, liver, kidney, and gill samples were collected from fish. On the taken tissue samples, malondialdehyde (MDA) level and some antioxidant enzyme (superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), and glutathione-S-transferase (GST)) activities were evaluated. The results demonstrated statistically significant increases in the MDA levels of the CPF-1 and CPF-2 groups. On the other hand, the MDA levels were significantly decreased by EA administration. Also, CPF exposure caused statistically significant increases in the SOD and GST activities and statistically significant decreases in the CAT and GPx activities. However, treatment with EA reversed negative alterations in the SOD, CAT, GPx, and GST activities. Therefore, the results of this study results showed that simultaneous treatment with EA alleviates CPF-induced oxidative stress in fish.

The effect of Hydroxyapatite (HA)-based coatings reinforced with reduced graphene oxide (rGO) on porous-Ti6Al4V (P-Ti6Al4V) alloys in terms of electrochemical corrosion and cell viability for potential biomedical applications was investigated in this study. The scaffold-porous surfaces of P-Ti6Al4V were coated by the biocomposite structure of HA and reduced graphene oxide (rGO) at various porosity rates (40, 50, and 60%) by using the sol–gel dip-coating method. The results of 0.5, 1.0, and 1.5 wt% rGO-HA coatings were compared to coatings that contained only HA (free-rGO). Raman spectroscopy, X-ray diffractometer, and scanning electron microscopy were used for structural and morphological characterizations. The coatings in vitro corrosion susceptibilities were tested in simulated body fluid at 37 °C. Compared to free-rGO coatings, the results showed that rGO reinforcements phases reduced the corrosion rate of the scaffolds. The corrosion rate increased as the porosity content of the scaffolds increased. In vitro cell viability tests revealed that samples of 0.5 and 1.0 wt% rGO-HA coating groups performed better than the control and 1.5 wt% rGO-HA samples.

Deniz, Fatma; Başgöz, Öyküm; Güler, Ömer; Mazmanci, Mehmet Ali
Studies, about products obtained from agricultural wastes, have increased within the scope of zero waste studies. The olive pomace is produced as a result of olive oil production. In the present study, activated carbon was synthesized using the olive pomace taken from the olive pomace processing plant operating with a three-phase process. The synthesized activated carbon characterization was performed using Scanning Electron Microscope (SEM), Fourier-Transform Infrared Spectroscopy (FT-IR), Brunauer – Emmett – Teller (BET), and X-Ray Crystallography (XRD) devices. Olive pomace activated carbon (OPAC) was used for the adsorption of dye from an aqueous solution. The adsorption efficiency of the OPAC was investigated. The initial pH value of dye solution (6–9), the amount of activated carbon (0.5 and 1.0 g/L), and initial dye concentration (600–1200 mg/L) were optimized. Also, adsorption kinetic and isotherm calculations were evaluated. The optimum parameters were found as the original pH value (pH=8) of dye solutions, OPAC amount of 1.0 g/L and the initial concentration of 1000 mg/L. The Langmuir isotherm model and the pseudo-second-order kinetic model were found as the most suitable models. It can be said that the synthesized material can be used at dye removing from wastewater.

The production of high-strength alkali-activated mortar and concrete by using waste materials instead of cement in order to reduce the amount of carbon dioxide released to nature in cement production is an important study that attracts the attention of researchers. In this study, self-compacting alkali-activated mortar samples were produced using boron waste (BW) and granulated blast furnace slag (GBFS). Prismatic samples of 40 × 40 × 160 mm and cubes of 50 × 50 × 50 mm were produced, in which 0%, 5%, 10%, 15%, 20%, 25% of BW were used. To achieve self-compacting alkali-activated mortar (SCAAM) slump-flow test method was conducted by per The European Federation of Specialist Construction Chemicals and Concrete Systems (EFNARC) guidelines. The samples prepared using Na2SiO3 (NS)/NaOH (NH) = 3.0 were exposed to oven curing at 60 °C and 100 °C for 3 days. The flexural and compressive strength (CS) values of 3, 28 and 90 days were obtained for the samples whose curing period was completed. According to the mechanical strength results, influence of capillary water absorption, porosity, water absorption and density and freeze-thaw from durability tests were carried out. After experimental tests, Scanning Electron Microscope (SEM) and Energy-dispersive X-ray Spectroscopy (EDS) images were utilized to determine microstructures of the samples. As a result of the study, it was determined that the highest strengths were obtained at the curing temperature of 60 °C. Also, it was seen that mechanical strengths and durability decreased with the increase in the BW ratio in the mixtures.
