Corrosion Testing and Evaluation of Inhibitors Performance
Abstract: Choosing test methods that will analyze specific needs, like film barrier strength that real field settings is essential for the proper evaluation and development of inhibitors. The flowing loop and the bubble test are two examples of the first and second, respectively. Corrosion is measured by gravimetric, electrical noise, alternating-current impedance, potentiodynamic measurement, linear polarization and gravimetric. The inhibitors action can be analyzed in different corrosive environments. Their performance is …

Well Injectivity Management during Geological Carbon Sequestration Activity
Abstract: It is well known that the saline aquifer formations are considered very reliable candidates for carbon sequestration because of their wide availability and they have good storage capacity. Due to high formation salinity, there a big concern about bore formation dry-out resulting from the salt precipitation in the form of halite (NaCl). The mutual solubility between CO2 and brine is responsible for creating the salt deposits, this processes may take …

Atmospheric Boundary Layer Processes: Impacts on Weather Patterns and Climate Change
Abstract: The atmospheric boundary layer (ABL) is a vital component of the Earth's climate system, acting as the interface between the terrestrial surface and the overlying atmosphere. This layer, typically extending from the surface to a height of a few hundred meters, is characterized by strong gradients in meteorological variables such as temperature, humidity, wind speed, and atmospheric pressure. Understanding the dynamics of the ABL is essential for comprehending weather phenomena, …

Design and Validation of an Artificial Intelligence-Driven Digital Twin for Real-Time Monitoring and Control in Polymer Composite Manufacturing
Abstract: Polymer Matrix Composites (PMCs) have become indispensable in high-performance sectors such as aerospace and automotive engineering, offering exceptional strength-to-weight ratios that outperform traditional metals in many demanding applications. However, the reliability of manufacturing PMCs via Vacuum-Assisted Resin Transfer Molding (VARTM) is frequently undermined by stochastic process variabilities. Unpredictable fluctuations in thermal history, preform permeability, resin rheology, and ambient conditions often lead to some defects; namely voids, dry spots, and incomplete …

Assessing the Suitability of Piped Water Supply for Tanker-fed Villages By Using WaterGems
Abstract: The Drinking water security has become a challenge for the country, specially in rural areas. So it is necessary to use available sustainable resources to resolve the problem. Many parts of Maharashtra face severe drinking water shortage in spite of high rainfall lying typically in the range of 2000-3000 mm. Aurangabad district alone has more than 100 tanker-fed villages, majority of which are concentrated in Paithan taluka. This study covered …

Effect of Initial Temperature and Diameter of Ethanol Droplet on Evaporation Dynamics in Convective Air Medium
Abstract: Ethanol is a suitable biofuel as it has fewer toxic emissions and higher-octane numbers. For spray combustion applications, the gas phase motion must be considered while numerically investigating the fundamental aspects of droplet evaporation and combustion processes. Hence, we have numerically simulated the evaporation dynamics of an isolated spherically shaped ethanol droplet under a forced convective air environment in the absence of gravity. The momentum transfer between two phases is …

Utilizing Metallurgical Wastes for the use of magnetic separation
Abstract: To enable a wider application of magnetic applications, concentration and purification parameters must be enhanced. The inventive fusion of electromagnetic gradients and multipurpose separations will establish new magnetic-based trends for large-scale downstream processing. More creative solutions are required for downstream processing to advance and resolve the problems facing bioprocessing today. Chromatography is the method that a conservative industry sector uses the most frequently. Chromatography provides a few benefits, but it …

Structure-Property Correlation in PTT/PP Blends with Improved Mechanical Performance
Abstract: The present work investigates a series of poly (trimethylene terephthalate) (PTT)/polypropylene (PP) blends prepared with varying PP concentrations in order to improve the overall performance of PTT, particularly with respect to mechanical properties and processability. PTT is a promising engineering thermoplastic owing to its balanced stiffness, resilience, and chemical resistance; however, its relatively high cost and processing limitations often restrict its wider application. In this context, blending with PP offers …

A Systematic Review on Peptic Ulcer Disease and its Pharmacological Treatment
Abstract: A chronic gastrointestinal condition known as Peptic Ulcer Disease (PUD) is typified by the formation of ulcers or mucosal erosions in the proximal duodenum and stomach. In the pathophysiology of PUD, the equilibrium between defensive processes like mucus and bicarbonate secretion, mucosal blood flow, and prostaglandin production, and aggressive factors such stomach acid secretion, pepsin activity, and Helicobacter pylori infection, is upset. Although stress and food have historically been blamed, …
