Evaluation of coping strategies of parents of children with cystic fibrosis.

This cross-sectional quantitative study was conducted to evaluate the coping strategies of parents of children with cystic fibrosis. The research sample is the parents (n: 112) who presented to Thoracic Medicine Department at Hacettepe University Pediatric Hospital between 3 April 2021 - 28 May 2021 and volunteered to participate in the study. Sociodemographic Data Form and Coping Orientation to Problems Experienced Inventory (COPE Inventory) were used in the collection of data. The study examined coping strategies according to children's characteristics such as age, sex, education, and parents' independent variables such as employment status, income status, number of individuals and children in the family, communication with other families, social and financial support. Data were analyzed using Mann-Whitney and Kruskal-Wallis tests. Research findings show that religious coping was the most frequently preferred coping strategy, and behavioral disengagement was the least commonly used coping strategy. Emotion-Focused Coping Strategies were also commonly used. Social work interventions and strategies play an important role in helping parents to adopt positive coping strategies and improve their skills.

Adsorptive removal of hazardous dye (crystal violet) using bay leaves (Laurus nobilis L.): surface characterization, batch adsorption studies, and statistical analysis.

In this study, the surface properties of Laurus nobilis L. were determined by inverse gas chromatography. From this, the surface of Laurus nobilis L. was found to be an acidic ([Formula: see text]). Then, the adsorption of hazardous crystal violet dye on Laurus nobilis L. was examined. For the adsorption process, the optimum conditions were determined as contact time (60 min), adsorbent dosage (1.0 g/L), agitation rate (200 rpm), and initial pH (≅ 7). The efficiencies of initial concentration, contact time, temperature, and their binary combinations on the improvement of adsorption percentage were statistically investigated via three different two-way ANOVA analyses. Adsorption data were applied to different isotherms, and it was determined that the Langmuir isotherm (r2 = 0.9998) was the most suitable isotherm for the adsorption process. The [Formula: see text] value was calculated as 400.0 mg/g at 25 °C from the Langmuir isotherm. According to kinetic models, it was observed that the adsorption occurred in three steps. According to enthalpy (+ 7.52 kJ/mol), activation energy (+ 8.91 kJ/mol), and Gibbs free energy (- 30.0 kJ/mol) values, it was determined that the adsorption occurred endothermically and spontaneously. As a result of reusability studies, it was determined that the adsorbent could be used repeatedly.

A comparative study of surface properties of Urtica dioica (nettle) leaves, roots, and seeds and examination of their ability to separate xylene isomers.

INTRODUCTION: Urtica dioica (nettle) is a plant species of the Urticaceae family that grows in various parts of the world and exerts antioxidant, antibacterial, antiulcer, antiviral, and anti-inflammatory effects. Their leaves, roots, and seeds are used in various fields such as food, medicine, and cosmetics. OBJECTIVES: Inverse gas chromatography (IGC) was used to evaluate the surface characteristics and separation ability of U. dioica leaves, roots, and seeds. Characterization of these biomasses was performed by Fourier transform infrared spectroscopy (FTIR) analyses. METHODOLOGY: The surface properties of the biomasses including dispersive surface energy, adsorption enthalpy, Gibbs free energy, and acidity-basicity constants were determined at infinite dilution using various organic solvents. These properties were compared with each other. Dispersive surface energies were calculated using the Dorris-Gray, Donnet-Park, and Schultz methods. The accuracy of these methods and their applicability were evaluated. In the last stage of this study, the separation of xylene isomers was investigated by using U. dioica biomasses as stationary phases. RESULTS: The surface functional groups were determined by FTIR analysis. As a result of the IGC studies, it was found that the adsorption of polar solvents on biomasses occurred exothermically and spontaneously. Besides, it was found that the surfaces of biomasses were basic. From the retention diagrams and selectivity coefficients, it was determined that xylene isomers were effectively separated. CONCLUSION: IGC is a promising, low-cost, easy-to-apply, and high-accuracy technique for the investigation of the surface properties of biomasses and their ability to separate isomers.

"They taught us not only our rights as women, but also how to live." Gender-based violence and empowerment experiences of Syrian women in Turkey and the role of women and girls safe spaces: A qualitative study.

Gender-based violence (GBV) is a women rights violation, particularly during humanitarian crises. Women and Girls Safe Spaces (WGSS) were opened within a project, where refugee women work and receive gender-sensitive services. The researchers aim to reveal the GBV exposure and empowerment experiences of Syrian refugee women in Ankara and WGSS' role. In-depth interviews were conducted with 26 health mediators working at WGSS. The findings obtained through thematic analysis revealed four main themes: changing forms of GBV during migration, learning women's rights as a means of resistance to GBV, experiences of women's working lives and empowerment, and changing gender roles.

Experiences of Divorced Women Subject to Domestic Violence in Turkey.

This study examines the experiences of divorced women who were subjected to domestic violence from their former spouses. The purpose of this study includes investigating violence in marital life and post-divorce, coping strategies for survival and external factors that empower/disempower women based on their life experiences. The study uses qualitative research methods. The data are retrieved from qualitative interviews with 13 women who were exposed to domestic violence while they were married and after their divorce. The participants were divorced through either informal or formal divorce procedures. Five themes emerged from the study: how to seek help, the endless circle of violence, divorce and family oppression, coping strategies, and awareness raising. The study shows that, during the divorce process, the participant women became more empowered and adopted better coping strategies than in the pre-divorce period. The study provides an understanding of domestic violence in the post-divorce phase. This research reveals the continuation of partner violence even after divorce.

Application of inverse gas chromatography in the surface characterization of diethanol amine modified polystyrene based polymer.

In the present work, diethanol amine modified polystyrene based polymer (PVBC-Diethanol amine) was synthesized and characterized, then surface properties of the polymer were examined by inverse gas chromatography method at infinite dilution. The retention diagrams obtained based on the interaction of polar and nonpolar probes with the polymer were drawn over a temperature range from 30 to 55 °C. Through the diagrams, the dispersive component of the surface free energy, g S D of the polymer surface, and the specific enthalpy of adsorption, DH A S , of probes on the polymer were also calculated. Lewis acid, K A , and Lewis base, K D , parameters of PVBC-Diethanol amine surface were determined. The values of K A and K D indicated that PVBC-Diethanol amine surface exhibited a basic behavior.

Evaluation of the surface properties of 4-(Decyloxy) benzoic acid liquid crystal and its use in structural isomer separation.

The selectivity of 4-(Decyloxy) benzoic acid (DBA) liquid crystal in surface adsorption region (303.2-328.2 K) and thermodynamic region (423.2 - 433.2 K) was investigated by inverse gas chromatography at infinite dilution (IGC-ID). The selectivity parameters of the structural isomer series named butyl acetate, butyl alcohol, and amyl alcohol series were calculated for the DBA using IGC-ID technique. Additionally, the surface properties including dispersive surface energy (gS D), free energy (DGA S), enthalpy (DHA S), and acidity-basicity constants were calculated with net retention volumes obtained from IGC-ID experiment results. When the DHA S and DGA S are constants, DBA surface was found to be an acidic character (KD/KA @ 0.89).
