This study investigates the effects of air injection on heat transfer performance in helical coil tube heat exchangers. Experiments were conducted varying air injection rates (0-50 L/min), injection locations (0%, 33%, 66% of coil length), coil diameters (300 mm, 450 mm), and water flow rates (0.1-0.5 kg/s). Results show significant heat transfer e...

Given the extensive and widespread utilization of fossil fuels in various sectors, there is a pressing need to explore and develop novel alternative fuels in order to effectively address the increasing global energy demand. The finite nature of fossil fuel reserves has resulted in their rapid depletion, thus highlighting the need to explore susta...

Internet of Things (IoT) integration allows for the monitoring and control of everyday objects through internet connectivity. This work describes the development and implementation of an IoT-enabled gas valve control and monitoring system. Through integration of Wi-Fi enabled microcontroller and sensor devices, a prototype system was built that all...

Introduction. Hypothyroidism is a common endocrine disorder that affects millions of people worldwide. The diagnosis and monitoring of this condition often rely on thyroid hormone levels, which can be limited in their accuracy. Pentraxin 3 (PTX3) is a protein family that is involved in the innate immune response and is distinguished by its distinct...

Background: Hypothyroidism occurs when the thyroid gland doesn't generate enough thyroid hormone. Meteorin like protein (Metrnl) a tiny secreted protein, regulates cell differentiation, survival, and migration in several organs. Aim of study: The purpose of this research was to see whether serum Metrnl levels might be used as a biomarker for hypoth...

The main stages of the primary materials are that feed the furnaces to form the mineral compounds of cement, which are the stage of drying the materials from water at a temperature of 100 degree Celsius and moving to the crystallization area at a temperature of 550 degree Celsius. Thus, the free lime begins to break down the calcium carbonate by in...

This paper aims to provide background information on raw materials included in the cement industry that have chemically examined. The raw materials entering the factory examined, which include stone, crude oil, iron dust, sand, and gypsum, as it found that the total carbonate ratio is 89 percent as a weight ratio and the sulfide is smaller or equal...
