Focusing on eco-friendly biosorption method: removal of reactive yellow-145 by natural ureolytic mixed culture
(Global NEST, 2025) Koçyiğit, Hasan; Manav, Esra
In this study, removal of reactive yellow 145 (RY 145) dyestuff by dry biomass of Ureolytic mixed microorganism culture (UMC), existing in domestic wastewater and various industrial wastewater, was studied. Optimum conditions of adsorption efficiency were tested. For this purpose, studies were conducted on the effect of initial dye concentration (30-50-75-100-150 mg/L), UMC amount (0.2-0.5-1.0-2.0 g), temperature (20-35-50 °C), pH (2-3-57-9) and contact time (1-5-10-20-30-60-120 min) on the efficiency of color removal. As a result of these studies, optimum conditions were revealed with 150 mg/L initial RY 145 concentration, 0.2 g dry UMC amount, 150 rpm agitation speed, 200C temperature, pH 2 and 30. minute contact time. After spectrophotometric calculations, according to Langmuir isotherm, it was found that 610.9 mg/g and the removal efficiency of tests was calculated as 84.5% under optimum conditions. It is seen that the process in which physisorption is at the forefront and single-layer adsorption occurs fits the Langmuir and pseudo-second order models. Thermodynamic data showed that the process occurred spontaneously and endothermically. The results support that UMC is both a promising and alternative environmentally friendly biosorbent for RY 145 removal.
Social work perspective on women’s empowerment women’s entrepreneurship
(CRC Press, 2025) Öztürk, Hatice
Women’s welfare is a priority issue in both national and international policies, and its importance has increased even more today. The emphasis on this issue in the Sustainable Development Goals is also noteworthy. In this regard, ensuring gender equality and empowering women is vital to ensuring that no one is left behind and to living a sustainable life. However, in most countries today, many women are exposed to inequalities due to factors such as poverty, injustice, and changing social and cultural norms. The social work profession focuses on the empowerment of women and benefits from its knowledge, skills, and value base in combating these inequalities. With an empowerment approach, social workers help unlock women’s potential and therefore encourage increased participation. Thus, women can realize their capabilities and have a say in politics, the health sector, education, and other fields. It is critical to recognize that female entrepreneurship is a powerful tool for women’s empowerment. Women’s entrepreneurship has important potential in terms of increasing women’s participation in working life and sustainability, as well as its impact on development. However, today’s deepening inequalities and inadequacies in implementation to ensure women’s welfare bring to the agenda the discussion of development approaches and policies. In view of this, the aim of this study is to discuss women’s entrepreneurship as a tool for empowering women from a social work viewpoint, benefiting from the existing literature.
Power consumption analysis of ESP32 and arduino nano for low-power applications
(Institute of Electrical and Electronics Engineers Inc., 2025) Demir, Hasan; Selçuk, İlayda; Coşgun, Atıl Emre
This study experimentally examined the energy usage of the ESP32 and Arduino Nano microcontroller boards in active and deep sleep (power-down) modes. Both boards were powered by a continuous 5 V voltage, and current measurements were obtained directly using a multimeter. The experimental results indicated that the ESP32 board consumed 45.5 mA in active mode and 5.27 mA in sleep mode, whereas the Arduino Nano consumed 18 mA in active mode and 5.39 mA in sleep mode. The power consumption of the ESP32 was determined to be 0.2275 W in active mode and 0.02635 W in sleep mode, whereas the Arduino Nano exhibited power consumption of 0.09 W in active mode and 0.02695 W in sleep mode. The statistics acquired demonstrate that both platforms are appropriate for low-power applications; however, the ESP32 shows more energy consumption in active mode, necessitating meticulous energy management planning during the design phase.
PET-CT indications and contributions to diagnosis in the rheumatology clinic: a retrospective analysis
(Springer Science and Business Media Deutschland GmbH, 2025) Kahraman Denizhan, Tuğba; Kaplan, Hüseyin; Kızıltepe, Melih; Kökoğlu, Emel Oğuz; Cengiz, Celil Barlas; Abdulrezzak, Ümmühan; Şenel, Abdurrahman Soner
Positron emission tomography-computed tomography (PET-CT) is a valuable imaging modality in both oncology and autoimmune or inflammatory diseases. This study evaluates the indications for PET-CT in rheumatology patients, compares PET-CT findings with other imaging modalities, and assesses its contribution to definitive diagnosis. Methods: Between January 2022 and December 2023, 63 patients (38 women, 25 men) who underwent PET-CT at Erciyes University Rheumatology Clinic were retrospectively analyzed. Clinical, laboratory, and imaging findings—including prior CT, magnetic resonance imaging (MRI), and angiographic evaluations—were reviewed. PET-CT findings were classified based on metabolic uptake patterns indicating malignancy, vasculitis, inflammatory involvement, lymphadenopathy, and IgG4-related diseases. PET-CT results were statistically compared with final diagnoses. Results: The most common indications for PET-CT were suspected vasculitis (42.9%), fever/inflammation of unknown origin (30.2%), and suspected malignancy (27.0%). PET-CT detected inflammation in 65.1% of cases, lymphadenopathy in 52.4%, nodules in 41.3%, malignancy in 31.7%, and vasculitis in 20.6%. Vasculitis findings were significantly higher in patients with pre-existing rheumatic disease (p = 0.012), while malignancy-related findings were more frequent in those without (p = 0.025). Anti-SSA and anti-Scl70 positivity were significantly associated with malignancy (p = 0.003 and p = 0.030, respectively). PET-CT effectively detected malignancy (p < 0.001) but showed limited diagnostic accuracy for vasculitis (47.6%). Conclusion: PET-CT complements conventional imaging in evaluating vasculitis, inflammation, and malignancy in rheumatic diseases. However, it is insufficient for diagnosing vasculitis alone, necessitating a comprehensive clinical and laboratory approach. While PET-CT is highly effective in malignancy detection, autoantibody presence should be carefully considered in suspected cases.
