The combined effects of polyethylene microplastics and benzoanthracene on Manila clam Ruditapes philippinarum
No full textMicroplastic (MP) toxicity has recently been explored in various marine species. Along with the toxicity of plastics polymer itself, additional substances or pollutants that are absorbed onto it may also be harmful. In the present study, we investigated the combined impacts of polyethylene microplastics (PE MPs) and an organic pollutant (Benzo(a)anthracene, BaA) on Manila clam Ruditapes philippinarum during a one-week exposure. Two PE MPs concentrations (26 mu g L-1 and 260 mu g L-1) and one BaA concentration (3 mu g L-1) were tested. The clams were exposed to BaA and PE MPs either alone or in combination. BaA and PE MPs were incubated before the combined exposure. The biological effects of PE MPs and BaA on the clams were evaluated by considering several assays such as feeding rate, anti-oxidant enzyme activities, and the expression levels of stress-related genes. The feeding rate significantly decreased in individual PE MPs and individual BaA groups while it remained un-changed in combined groups. Superoxide dismutase (SOD) was the most affected among the biochemical pa-rameters. Malondialdehyde (MDA), and glutathione peroxidase (GPx) activities were slightly affected, whereas no changes were observed in glutathione s-transferase (GST) activities. CYP1A1, CYP3A4, and HSP70 gene ex-pressions displayed slightly significant changes. Considering all stressor groups, high PE MPs exposure (260 mu g L-1 PE MPs) more effectively altered the biological parameters in the clams compared to individual low PE MPs and BaA exposure, and their combination. The results also indicated the negligible vector role of PE MPs to transport BaA into the clam tissues
Professional attitude and self-respect of generation X and Y nurses
No full textObjectives: This study aims to investigate Generation X and Y nurses' attitudes toward the profession and their professional self-respect. Methods: This is a descriptive study. The sample comprised 356 nurses working in a hospital and family health center. The data were collected using an information form regarding sociodemographic and professional characteristics, the Attitude Scale for Nursing Profession, and the Scale of Professional Self-respect. Results: Of the nurses, 28.1% were from Generation X and 71.9% were from Generation Y. Attitudes toward the profession and professional self-respect were positive in Generation X and Y nurses. Attitudes toward the profession scores were higher for Generation X than for Generation Y nurses; however, no difference was found between the generations in professional self-respect. Conclusion: A positive, moderate-level significant relationship was found between professional self-respect and attitudes toward nursing in both Generations X and Y. The study results can be utilized to strengthen nurses' professional attitudes and self-respect and to develop recommendations for effective teamwork for nurses in different generations
Experiences lived by international nurses concerning professional integration and interpersonal relationships in the workplace: qualitative research
No full textPurpose: The recruitment of international nurses has been used for a long time to address the global nurse shortage. In 2012, the employment of international nurses was released in Turkey. Cultural differences can hinder interpersonal relationships, and fostering strong interpersonal relationships among nurses in the workplace is known to have a positive impact on productivity, job satisfaction and the quality of care provided. This study aims to explore the lived experiences and perceptions of international nurses working in Turkey regarding their professional integration and interpersonal relationships in the workplace. Design/methodology/approach: It is a qualitative descriptive study. Face-to-face interviews were conducted with 19 international nurses using a semi-structured form. Data were analyzed using thematic analysis. Findings: Data were presented into two themes: (1) Interpersonal relationships in the workplace and (2) Professional integration. Participants reported positive and negative experiences regarding interpersonal relationships in the work environment, such as warm and supportive approaches, or exclusionary and discriminatory behaviors. The existence of different nursing practices, positive and negative factors concerning orientation programs and the gain of experience and professional satisfaction were mentioned by the participants. Originality/value: This is the first study to explore the lived experiences and perceptions of international nurses working in Turkey. The study highlights the unique needs and challenges faced by international nurses during workplace adaptation and provides practical recommendations to facilitate interpersonal relationships in the workplace and other aspects related to professional integration from hiring to the end of the adaptation period. © 2023, Emerald Publishing Limited
RB1 gene mutations and genetic spectrum in retinoblastoma cases
No full textThe aim of the study was to investigate the frequency and types of mutations on the retinoblastoma gene (RB1 gene) in Turkish population. RB1 gene mutation analysis was performed in a total of 219 individuals (122 probands with retinoblastoma, 14 family members with retinoblastoma and 83 clinically healthy family members). All 27 exons and close intronic regions of the RB1 gene were sequenced for small deletions and insertions using both the Sanger sequencing or NGS methods, and the large deletions and duplications were investigated using the MLPA analysis and CNV algorithm. The bilateral/trilateral retinoblastoma rate was 66% in the study population. The general frequency of RB1 gene mutation in the germline of the patients with retinoblastoma was 41.9%. Approximately 51.5% of the patients were diagnosed earlier than 12 months old, and de novo mutation was found in 32.4% of the patients. Germline small genetic rearrangement mutations were detected in 78.9% of patients and LGRs were detected in 21.1% of patients. An association was detected between the eye color of the RB patients and RB1 mutations. 8 of the mutations detected in the RB1 gene were novel in the study
Design and Realization of Broadband Active Inductor Based Band Pass Filter
No full textWith the latest developments in the wireless communication systems, the alternative design methodologies are required for the broadband design of microwave components. In this paper, a compact broad band pass filter (BPF) design is introduced through the microwave design technique based on the active inductor (AIN) with the numerical computation and experimental measurement studies. The proposed AIN based BPF has operating frequency band extending from 0.8 GHz to 2.7 GHz in compact size with high selectivity in comparison to conventional LC based BPF. The experimental measurement results agree well with the numerical computation results. The proposed AIN based BPF design has technical capability to be conveniently tuned to operate at different frequency bands
Calculation of the Phase Diagrams (T - X and T - P) and the Thermodynamic Quantities for the Solid - Liquid Equilibria in n-tridecane
No full textThe solid – liquid equilibria in n-tridecane is investigated by calculating phase diagrams and the thermodynamic quantities using the Landau phenomenological model. By expanding the free energy in terms of the order parameter of the solid phase, the phase line equations are fitted to the experimental data for the T – X and T – P phase diagrams from the literature. The temperature dependences of the thermodynamic quantities (order parameter ψ, susceptibility χψ, free energy F, the heat capacity C, entropy S and the enthalpy H) are predicted for the n-tridecane from this model. Our results give that the slope dT dP/ ≅ 2 K/MPa for n-C13 to n-C17. ψ varies with T as ψ~(T − Tm)1 2⁄ above Tm. It is linear for the χψ−1, S(T) and C(T), and quadratic for the F(T) and H(T) in n-tridecane. This indicates that the Landau model, describes the observed behaviour of the phase diagrams satisfactorily for the solid – liquid equilibria in n-tridecane. Predictions of the thermodynamic quantities can also be compared with the measurements and predictions of some other theoretical models. The pressure effect, in particular, on the solid – liquid equilibria in n-tridecane can also be investigated under the model studied here. © 2023 International Journal of Thermodynamics.

The effect of politics on the formation of urban aesthetics, the case of Iran
Get PDFUrban aesthetics is a complicated issue that needs further evaluation of its physical specifications in a city. This article examines urban aesthetics through the historical political patterns and urban planning and development process. The aim is to reveal the relationship between the formation of urban aesthetics, the urban planning process, and the political impact. Iran as the case of a developing country with a different socio-political context and national system is selected for this aim. Path-dependency analysis has been used as a methodology to provide a framework to understand urban aesthetics followed by different socio-political periods and planning processes. Three political periods have been selected for analysis in which the country gained most of its unprecedented changes in political, and social aspects. Analysis results demonstrated that urban aesthetics is more dependent on the political path dependency than the planning process while still the same planning approaches have been carried out in the country. © 2022 Elsevier Lt
Compassion Fatigue in Nurses Providing Palliative Cancer Care and Coping Strategies to Prevent and Manage it
No full textObjectives: End-of-life care for cancer patients is one of the most challenging experiences encountered by nurses. Cancer nurses providing end-of-life care may experience compassion fatigue due to prolonged exposure to the suffering and intense emotional reactions of patients, death and the dying, and grieving families. However, the development of resilience and effective coping skills can decrease nurse turnover rates and increase the quality of palliative cancer care. This article discusses the concept of compassion fatigue, how it develops, compassion fatigue experienced by nurses providing palliative cancer care, and the Compassion Fatigue Resiliency Program (CFRP) coping method. Data Sources: Author experience and journal articles were used. Conclusion: Compassion fatigue can occur from secondary traumatic stress and burnout after nurses’ prolonged and intense exposure to helping suffering patients, resulting in decreased ability to care, expend energy, or exhibit empathy and compassion. The CFRP is a structured, comprehensive training program designed to educate nurses about compassion fatigue and enable them to develop a support network, strengthen their coping skills, and improve resilience. Implications for Nursing Practice: It is recommended that the CFRP be included in in-service training in institutions and be applied to oncology nurses at regular intervals in a block program format (1–2 days). Newly recruited oncology nurses in particular should be supported with such training in orientation programs. Institutional managers play an important role in organizing such programs and screening for the risk of compassion fatigue in nurses who provide end-of-life care. © 2023 Elsevier Inc
Measurement of e+e- → ωπ+π- cross section at <mml:msqrt>s</mml:msqrt>=2.000 to 3.080 GeV
No full textA partial wave analysis on the process e+e− → ωπ+π− is performed using 647 pb−1 of data sample collected by using the BESIII detector operating at the BEPCII storage ring at center-of-mass (c.m.) energies from 2.000 GeV to 3.080 GeV. The Born cross section of the e+e− → ωπ+π− process is measured, with precision improved by a factor of 3 compared to that of previous studies. A structure near 2.25 GeV is observed in the energy-dependent cross sections of e+e− → ωπ+π− and ωπ0π0 with a statistical significance of 7.6σ, and its determined mass and width are 2232 ± 19 ± 27 MeV/c2 and 93 ± 53 ± 20 MeV, respectively, where the first and second uncertainties are statistical and systematic, respectively. By analyzing the cross sections of subprocesses e+e− → ωf0(500), ωf0(980), ωf0(1370), ωf2(1270), and b1(1235)π, a structure, with mass M = 2200 ± 11 ± 17 MeV/c2 and width Γ = 74 ± 20 ± 24 MeV, is observed with a combined statistical significance of 7.9σ. The measured resonance parameters will help to reveal the nature of vector states around 2.25 GeV. [Figure not available: see fulltext.] © 2023, The Author(s)
MATCH OF TuRKIYE'S PROGRAM BUDGET WITH THE SUSTAINABLE DEVELOPMENT GOALS
No full textThe documents that embody the goals that the states want to achieve are the budgets. With this feature, budgets; it gives clues about how states will follow a path to ensure administrative, economic , environmental sustainability. The Sustainable Development Goals, which were set forth by the United Nations with the aim of "leaving no one behind", were accepted by 193 countries to be realized between 2015 and 2030. Turkiye is also among these countries. In our study, it is aimed to examine to what extent the program budget, which entered into force as of 2020, serves the United Nations Sustainable Development Goals (SDGs). In this context, 17 SDGs and 67 budget programs were matched , it was revealed how much share was allocated to each SDG from the budget. Turkiye ranked 71st among 163 countries in the SDG index in 2021. As a result of the study, it was determined that Turkiye could not allocate sufficient resources from the budget to realize some SDGs. It is considered that Turkiye may rise rapidly in the SDG index with the preparation of budget programs in line with SDGs in the upcoming period. In addition, it is evaluated that the new budget system can take on a sustainable development-oriented structure
