    Abstract: The assessment of potential commercial antiscalants is one of the most important issues for geothermal power plants. With a variety of alternative products available and companies making strong claims, it is difficult for power plant engineers to select the best antiscalant for their system to reduce the unwanted formation of deposits. Products need to be tested in the plant, but this can have a negative impact on the plant’s process. It is advisable to develop a testing approach using the original brine from the field instead of testing the potential products in the power plant. In this study, we propose an in vitro study to monitor the formation of geothermal deposits using a device we have developed. The pressure difference gives a reliable indication of the formation of the deposits. As a model for a geothermal field, this device is connected to a system already in operation on the west coast of Türkiye, the Karyek geothermal power plant. The results indicate that tracking the pressure difference between two parallel lines of the power plant at different times provides indications of the formation of deposits in a power plant. Furthermore, this design allows the selection of the best antiscalant among many other commercial alternatives.

    Abstract: Nigella sativa is a plant belonging to the Ranunculaceae family, naturally occurring in Southern Europe and Western Asia. Widely cultivated worldwide, this plant has been esteemed and considered sacred in traditional medical systems such as Unani, Ayurveda, Siddha, and Tibb-e-Nabawi for thousands of years. It is known to have therapeutic effects on various conditions including gastrointestinal disorders, skin problems, diabetes, and cancer. Additionally, it is used in cosmetic applications for combating hair loss and in anti-aging skincare. This study focuses particularly on highlighting the effects of black seed on celiac disease. Furthermore, it aims to summarize the pharmacological effects of bioactive compounds found in Nigella sativa such as thymoquinone, p-cymene, carvacrol, thymol, and trans-anethole, and to evaluate recent research findings in this field.
