An Essay Discussing Budd-Chiari Syndrome
Abstract: Budd-Chiari syndrome (BCS) is defined as hepatic venous outflow tract obstruction, independent of the level or mechanism of obstruction, provided the obstruction is not due to cardiac disease, pericardial disease, or sinusoidal obstruction syndrome (veno-occlusive disease). Primary Budd-Chiari syndrome is present when there is obstruction due to a predominantly venous process (thrombosis or phlebitis), whereas secondary Budd-Chiari is present when there is compression or invasion of the hepatic veins and/or …

SoloRider: An Autonomous Self-Balancing Electric Bike for Sustainable Urban Mobility
Abstract: Rapid urbanization has intensified challenges such as traffic congestion, parking inefficiency, and environmental degradation. While autonomous vehicle research predominantly focuses on four-wheel platforms, lightweight two-wheelers remain comparatively underexplored. Two-wheelers are a great option for sustainable urban transportation because of their many benefits, including their small size, lower energy consumption, better manoeuvrability, and lesser infrastructure requirements. This paper presents SoloRider, a conceptual autonomous self- balancing electric two-wheeler de- signed for sustainable …

Pore Distributions in Porous Anodic Aluminum Oxide (PAAO) Surfaces of Pure and Commercial Aluminum Substrates
Abstract: Porous anodic aluminum oxide (PAAO) surfaces were developed on pure aluminum (PA) and commercial aluminum (CA) substrates by anodization as a function of voltage in phosphoric acid bath at 278 K and were analyzed by scanning electron microscopy. The interpore distances were plotted in the form of frequency histograms to examine pore-ordering characteristics. Self-ordered porous structures have been obtained at 200 and 160 V for PA and CA substrates respectively …

Prediction of Punching Shear Capacity of Biaxial Voided Slab
Abstract: Biaxial voided slab systems are advantageous due to their reduced self-weight, up to 50 % in comparison with the conventional reinforced concrete solid slab. The reduction in the concrete cross sectional area reduces the shear capacity up to about 40 %. The prediction of punching shear capacity in voided slab is not direct unlike in solid slab. This is because the presence of voids alters the critical failure section and …
