Short arc orbit determination for GEO satellites is useful when there are gaps or incomplete data due to limited time or other factors. Full cycle orbit determination requires continuous data over the entire orbit cycle, which may not always be available. This research assesses the accuracy of short arc orbit determination for GEO satellites for various time intervals ranging from 6-hour- to 42-hour intervals using two data collecting techniques: azimuth elevation range (AER) and range-to-range (RNG). Iterative Least-Squares Estimation, a numerically integrated method, is then used to determine the orbit, by either calculating new bias values or pre-existing bias values. The results show that average root mean square error (RMSE) values are 0.792 km and 0.160 km for AER and RNG type observation data, respectively, using pre-existing bias values. On the other hand, using new bias calculation, the average RMSE values are 36.480 km and 6.254 km for AER and RNG. The findings indicate that the RNG method provides superior accuracy in determining the orbit for both satellites. The study recommends the use of pre-existing bias values over calculating new ones. Short arc orbit determination can provide a reasonable estimate of the satellite's orbit when a limited amount of data is available due to various reasons and can also be used to quickly assess and correct any deviations or errors in the satellite's orbit, improving overall accuracy and reliability.

Although the term "mullah" could be used for various coteries, it could be said that this concept is generally a scholarly appellation used for all madrasah graduates, whether they perform a religious mission or not. Enlightening the historical background of the mullahs, who have lost social value since the last periods of the Ottoman Empire, is of great importance in illuminating the Islamic social history of the Ottoman period. In this study, the mullahs, who have been left in the dark up to now and their places in the social network of the period were unknown, are the subject of research. The examined database of the research is the court records of the period of the 18th century, which is the most important and first-hand source of Ottoman social history studies. The data and findings obtained in the current study were examined under the headings of family relations, professions, economic relations, social roles and statuses, conflicts in the society, and criminal relations of the mullahs. All the data and findings obtained from the court records of the research have revealed that the mullahs were actively taken a role in the social life in Ottoman Cyprus. In addition, it has been revealed that they were respected and reliable people who add value to society, improve social life, and were an important part of the social history of Cyprus.

Objective: The aim of this study was to compare clinical and histopathological effects of oral versus intraarticular corticosteroid application in a rat model of frozen shoulder., Methods: In this study, eighty adult Sprague-Dawley rats were used. The animals were divided into 5 equal groups. The frozen shoulder model was created by immobilizing animals' shoulders with internal fixation with sutures for 8 weeks. At the 8th week, sham (n: 16) and control (n: 16) groups were sacrificed to collect data for healthy and affected shoulders. Also, at the 8th week, 50 mg/ kg methylprednisolone was started for the oral treatment group, and a single dose of 0.5 mg/kg triamcinolone acetonide was injected for the intraarticular treatment group. The effect of additional steroid treatment was expected for 2 weeks, then all remaining treatment and natural course groups were sacrificed on the 10th week., Results: After sacrification, specimens taken as "en bloc" scapulothoracic disarticulation were randomly divided into two groups for a range of motion measurement and histopathological examination. The control (frozen shoulder model) group's shoulder range of motion in all directions was lower than the sham (healthy) group (P < 0.01). Natural course and intraarticular steroid groups, compared to the frozen shoulder model showed a significant increase in the direction of abduction (P < 0.05). Also, it was found for treatment groups that in all directions the range of motion was not as good as the healthy values (P < 0.01). The intraarticular treatment group showed higher degrees of abduction compared to the natural course and oral steroid treatment groups (P < 0.01). Oral steroid treatment group's range of motion was not significantly better than the disease model and had no superiority to the natural course group (P > 0.05). Histopathologically, no statistically significant difference was observed between the groups for signs of frozen shoulder which was found in the immobilized group (P > 0.05). Histopathologically, immobilization was found to cause thickening of the capsule that cannot be resolved by treatment. (P < 0.05)., Conclusion: In frozen shoulder disease, intraarticular steroid injection seems to be superior in increasing the range of motion than oral steroid treatment.
