Evaluating an ai-supported experiential learning intervention: a quasi-experimental study of the joyful saturday model for student engagement and holistic development
Abstract: Student disengagement, declining academic motivation, and passive classroom participation remain major challenges in modern higher education systems. Traditional lecture-based teaching methods often fail to accommodate diverse learning styles and do not sufficiently promote active participation or collaborative learning. To address these challenges, the present study evaluates the effectiveness of Joyful Saturday, a structured experiential learning initiative designed to improve student engagement, motivation, and holistic development through interactive academic activities supported …

Establishment of Wax Deposition Index from Saturates, Aromatics, Resins, Asphaltenes Analysis
Abstract: Saturates, aromatics, resins, asphaltenes (SARA) analysis is one method of characterizing crude oils. It is versatile because it can apply to many components of the crude oil. SARA analysis furnishes one with the composition of any crude and ultimately gives an idea of the potential of the crude oil to precipitate and deposit wax. This analysis method usually breaks crude oil down into four components (saturates, aromatics, resins and asphaltenes) …

Relative Permeability Study in Part of Geleki Oil field of Upper Assam Basin
Abstract: Relative permeability is a critical parameter for evaluation of reservoir performance. Relative permeability is a direct measure of the ability of the porous medium to allow flow of one fluid when two or more fluids are present. This flow property is the composite effect of pore-geometry, wettability, fluid saturation, saturation history, reservoir temperature, reservoir pressure, overburden pressure, rock-types, porosity and permeability types. The relative permeability curves are very important in …

Evaporative Cooling By Using Different Porous Materials
Abstract: The method of evaporative cooling involves raising the air temperature by causing water vapour in an airstream to evaporate. Waterneeds the latent heat of vaporisation to evaporate, and this heat is produced by ambient air and a drop in air temperature. A porousmedium is necessary for both direct and indirect evaporative cooling in order to allow heat and mass transfer between the medium'swater and the air moving through it, or …

Iron Profile in Gestational Diabetes Mellitus
Abstract: Background: The precise mechanisms behind the etio-pathogenesis of gestational diabetes mellitus (GDM) are unknown. According to epidemiological evidence, GDM is linked to higher body iron reserves. Higher serum ferritin levels, which are widely employed as a marker of the body's iron store, have been observed in people with diabetes mellitus. The goal of this study was to see if this occurred in GDM women. Materials and Methods: From April 2023 …

Foundation of Building
Abstract: Recent trends in civil engineering underscore the importance of designing foundations that can withstand varying load conditions and environmental challenges. Selecting the appropriate foundation depth is critical for stability, particularly under intense loads. In regions with high rainfall, understanding maximum precipitation levels and water infiltration is vital. Water penetration into the soil can significantly reduce its load-bearing capacity, with saturation potentially lowering it by up to 50%. Foundations must also …

Pulse Oximeter using PSoC
Abstract: A pulse oximeter to measure the oxygen saturation in blood as well as heart rate was developed using PSoC. The method proposed here is to transmit light of two different wavelengths through the finger and tissues and to measure the change in absorption intensities. The signals are obtained as photoplethysmograph (PPG) waveforms. The pulse oximeter finds the variations in both the waveforms and calculates the SpO2 and heart rate of …

Headway Compression during Queue Discharge at Signalized Intersections under Mixed Traffic Condition
Abstract: The evaluation of capacity at signalized intersection is an important component in the planning, design, operation and management of transportation system. Presently, the methodologies available for the estimation of capacity of signalized intersections are based on the concept of saturation flow(s). Saturation flow is the steady maximum queue discharge rate after the green onset. According to the U.S. Highway Capacity Manual, this steady maximum rate is generally achieved after the …
