Innovative solutions for combating climate change: advancing sustainable energy and consumption practices for a greener future
(Multidisciplinary Digital Publishing Institute (MDPI), 2025) Erdoğdu, Aylin; Dayı, Faruk; Yanık, Ahmet; Yıldız, Ferah; Ganji, Farshad
This paper investigates strategies to address climate change by promoting sustainable energy technologies and consumption practices. It examines renewable energy sources such as solar, wind, and geothermal and their potential to reduce greenhouse gas emissions. The study also explores energy optimization techniques, focusing on genetic algorithms (GAs) and smart energy systems like smart grids and microgrids, which enhance energy efficiency and sustainability. The research highlights the role of the circular economy in fostering sustainable consumption through recycling and waste management. Furthermore, the paper explores the economic trade-offs between energy consumption and environmental harm, focusing on the impact of both renewable and fossil fuel energies. A dual methodological approach is employed: first, an endogenous growth model excluding environmental factors, followed by a modified version incorporating environmental considerations. Using a continuous genetic algorithm and data from 2000 to 2025, the study forecasts the optimal trajectory for renewable energy’s share in global energy consumption under two scenarios. The findings suggest that by 2025, renewable energy could represent 82.4% of the total energy consumption under environmental constraints, up from the current share of 45%. This growth is hindered by challenges like droughts, which impact hydropower production. The study concludes that achieving a sustainable energy transition requires comprehensive policies integrating renewable energy expansion, energy efficiency, and environmental protection. These findings provide important insights into optimizing energy pathways for economic growth and environmental sustainability. They also serve as a foundation for future research and policy recommendations, aiming to ensure a low emission future by balancing the need for energy consumption with the preservation of the environment.
The impact of N-acetylcysteine on early periods of tendon healing: histopathologic, immunohistochemical, and biomechanical analysis in a rat model
(Taylor and Francis Ltd., 2025) Büyükdoğan, Halil; Ertürk, Cemil; Eren, Erdal; Öztürk, Çiğdem; Yıldırım, Burak; Sarıtaş, Tahir Burak; Demirkol, Metehan
Purpose: This study aimed to evaluate the early effects of N-acetylcysteine, which has antioxidant, inflame-modulatory, and cytoprotective properties, on tendon healing. Materials and methods: Thirty-five male Wistar Hannover rats were divided into five groups: first-week treatment (Group 1T), first-week control (Group 1C), third-week treatment (Group 3T), third-week control (Group 3C), and native tendons (Group N). Bilateral Achilles tenotomy was performed on all rats except Group N. After tenotomy, 150 mg/kg N-acetylcysteine was administered daily intraperitoneally to treatment groups, while isotonic saline was given to the control groups. Tendons were evaluated histopathologically, immunohistochemically, and biomechanically after sacrifice in the first and third weeks. Results: No significant differences were observed in the first week (p > 0.05). Movin and Bonar scores (lower scores reflect improved histologic healing) were significantly lower in Group 3T than in Group 3C (p = 0.002). Collagen type-I/type-III ratios were higher in Group 3T compared to Group 3C (p = 0.001). Fmax (N) values were similar across Group 3T, Group 3C, and Group N (p = 0.772). However, cross-sectional areas (mm2) were significantly smaller in Group 3T than in Group 3C (p = 0.001), with the smallest areas observed in native tendons. Thus, tensile strength (MPa, load per unit area) and toughness (J/103 mm3, energy absorbed per unit volume) were significantly higher in Group 3T than in Group 3C (p = 0.001). Conclusion: N-acetylcysteine supplied some improved results on early markers of tendon healing. Although our findings support the potential of NAC as a therapeutic adjunct in tendon injuries, further studies are needed to evaluate the long-term effects and underlying mechanisms.
On cutting coal dependency for establishing a cleaner energy mix: A proposal for energy transition strategy in South Africa
(Elsevier, 2025) Erdoğan, Sinan; Pata, Uğur Korkut; Alola, Andrew Adewale; Echebiri, Chukwuemeka
Although coal has powered economic activities for decades and significantly contributed to increasing economic welfare at the global level, its place in the modern economic system remained controversial because of its environmental impacts. Thus, cutting coal utilization and dependency on this energy source posits a great environmental benefit. With is motivation, the primary motivation of this study is to investigate the role of possible cleaner energy alternatives in cutting coal dependence in South Africa, which is prevalently utilizing coal in energy. To this end, the study employs Fully Modified Ordinary Least Squares (FMOLS) as a baseline estimator and Canonical Regression (CCR) as a robustness check from 1984 to 2022. The obtained outcomes denote that (i) an inverted U-shaped nexus exists between economic growth and coal utilization in some models. (ii) Renewable and hydro energy use has a negative and statistically significant impact on coal use, while nuclear energy and natural gas have no statistically significant impact. (iii) Population density spurs coal utilization. (iv) Robustness checks imply that empirical outcomes are substantially robust. In this regard, South Africa could reduce the demand for coal with renewable and hydro energy sources.
Why do so few individuals with an autism spectrum disorder attend university? A case of Turkiye
(Springer, 2025) Yazıcı, Mahmut Serkan
This study examines the barriers faced by individuals with autism spectrum disorder (IWA) in Turkish higher education. A phenomenological design was employed, involving 18 participants, including IWA, parents, lecturers, and friends with relevant experience. Data were collected through semi-structured interviews. The findings indicate that the challenges faced by IWA begin in childhood and persist throughout their university education. The study highlights the critical role of parental involvement in overcoming these barriers. It is suggested that this primary responsibility should shift from being managed by parents to being guided by policies. Additionally, it underscores the importance of integrating cultural factors into the development of policies that support IWA in higher education.
A quantitative approach to the wealth of ottoman women
(Istanbul University Faculty of Letters, 2025) Yıldız, Sema Keleş
This article quantitatively examines women’s wealth in İstanbul in the first half of the 18th century, using inheritance records extracted from İstanbul Court Registers. This study aims to analyze the economic status of women and the factors influencing them based on wealth-related data. This study starts with a general assessment of the wealth distribution in İstanbul in the first half of the 18th century, followed by an interpretation of individual wealth by gender. The present study also tries to explain the gender wealth gap (GWG) by linking it to the sources of women’s wealth. Additionally, it attempts to profile wealthy women, examine their wealth sources and components, and assess the relationship between titles and wealth. In the present study, quantitative findings were interpreted statistically, supported by qualitative findings. In addition, Mann-Whitney U and Kruskal-Wallis H tests were applied to determine whether there is a statistically significant difference between gender-wealth, debt-wealth, and title-wealth variables. As a result, it is concluded that women’s limited sources of wealth accumulation play a crucial role in creating a gender wealth gap between women and men in high-wealth groups; the level of borrowing by gender influences the difference in the gender wealth gap between total and net wealth, and a significant relationship exists between women’s title and their wealth.
