    Agrivoltaic systems for sustainable energy and agriculture integration in Turkey
    (Elsevier Ltd, 2024) Coşgun, Atıl Emre; Endiz, M.S.; Demir, H.; Özcan, M.
    In recent years, the use of solar photovoltaic (PV) energy, which is one of the leading renewable energy sources, has become increasingly widespread around the world due to its numerous advantages. However, PV-based electricity generation necessitates a large amount of land. Agrivoltaic (AV) systems, an innovative approach to combining agricultural and electricity production in the same area through solar modules positioned several meters above the surface of the ground, are growing rapidly in renewable energy and farming communities. This study explores Turkey's solar power generation and agricultural activities, combining crop cultivation and electricity generation for sustainable development on the same land. Furthermore, the AV potential for the most agriculture ten cities in different climate zones in Turkey is investigated using the PVsyst program. A list of the most commonly grown crops in the ten selected cities and the types of AV systems that can be employed with these crops is provided. The results show that AV systems present a great opportunity for the optimal integration of solar power generation with food production, especially for the cities of Konya, Kayseri, and Manisa, with the most ideal conditions for agricultural and solar power production. By combining the solar power potential of the country with the production capacity of arable lands, the increasing energy needs can be met and more efficient agricultural production can be provided. This study is expected to demonstrate that in specific regions of Turkey, AV farming will be suitable for certain

    The effects of preparation period exercises on the hematological parameters of the taekwondo athletes
    (Natl Olympic Committee Ukraine, Kharkov Regional Branch, 2019) Boyalı, E.; Sevindi, Tarık; Yüksel, M. F.; Demir, H.
    Purpose: This study aimed at examining the effects of preparation period exercises, which were applied for eight weeks to elite level taekwondo athletes, on the hematological parameters. Material: Totally 21 athletes with international degrees from the university taekwondo team participated in this study, 12 of whom were female (Mean age: 20.3 - Mean exercise age: 8.8) and 9 of whom were male athletes (Mean age: 20.3 - Mean exercise age: 9.5). The participants attended an 8-week exercise program for 5 days a week, which included basic motoric features and technical and tactical development. 4 cc blood samples were taken from the right antecubital vein before and after the preparation period exercises. On the blood samples,WBC, GRAN, GRAN %, LYM, LYM %, MID and MID % values were examined among leukocyte sub-groups; RBC, HGB, HCT, MCV, MCH, MCHC and RDWC values were examined among the erythrocyte sub-groups, and PLT, MPV, PCT and PDW values were examined among thrombocyte sub-groups. Results: At the end of the study, we determined that there was a statistically significant increase in the MCHC values of both the male and the female taekwondo athletes. Moreover, it was determined that there were statistically significant decreases in the HCT, MCV, MCH, MPV and PCT values of the female taekwondo athletes, and in the MCV, MPV and PCT values of the male taekwondo athletes. Conclusions: As a conclusion, we can state that the 8-week exercises applied during the preparation period affected the hematological parameters of the male and female taekwondo athletes to an extent, however, this effect was limited and it did not cause an important change.
