Nanoenabled resinbased composites in restorative dentistry: mechanical performance, aesthetic outcomes, and global regulatory considerations
Abstract: Resinbased composites are central to contemporary restorative dentistry but remain constrained by polymerization shrinkage, wear and color instability, which compromise longterm restoration success. Nanoenabled resinbased composites (nanocomposites) have been developed to overcome these limitations by incorporating nanosized fillers and engineered nanostructures into conventional resin matrices, thereby enhancing mechanical properties and optical performance. This narrative Review summarises current evidence on the evolution, composition, and mechanisms of nanoenabled resinbased composites; compares their …

Analyze Effect Of Skew Angle On Performance of R.C Girder Bridge Deck
Abstract: Abstract - The performance of reinforced c oncrete (R.C) girder bridge decks is significantly influenced by geometric configurations, among which the skew angle plays a critical role. Skewed bridges are commonly employed to accommodate site constraints, road alignment, and river crossings, but they introduce complex stress distributions, torsional effects, and differential deflections compared to straight bridges. This study investigates the effect of varying skew angles on the structural behavior of …

Computational Investigation on Performance of Rib Roughened Channel
Abstract: ABSTRACT: Improving the heat transfer efficiency of machinery is crucial since it can result in savings on energy, materials, and expenses. Rib-roughening on the heated plane is one method of increasing rate of heat transfer. Rib roughened surfaces are utilized in various industrial applications. Rib roughened surface disturbs the laminar sub-layer and increases the turbulence. Because of increase of turbulence and mixing, rate of heat transfer is improved. Pressure loss …

A Review: Performance analysis of overlapping shear keys in box girder bridges using finite element based software
Abstract: Abstract - Box girder bridges are widely used for long-span constructions due to their high strength-to-weight ratio and structural efficiency. A fundamental component in these bridges is the shear key which allows for effective transfer of loads between bridge segments and upholds the overall structural performance through the different load cases. Overlapping shear keys are becoming increasingly popular because they greatly enhance inter-segment connections, which decrease relative displacements. This paper …

The Psychological Effect of Landscape Architecture on the Student’s Academic Performance
Abstract: Landscape architecture is the outline of outside open areas, points of interest, and structures to accomplish natural, social-behavioral, or stylish results. When Fredrick Olmsted generated the field of landscape architecture in the late 1800's, he strongly stated that landscape added a significant conception of beauty. Consequently, Architects nowadays often engage elements of greenery in order to enhance the overall design that they've made. Also, latest landscape projects have included social …

Desizing of Cotton Fabrics With Enzymes for Improved Performance
Abstract: Desizing of cotton substrates with Amylase enzymes has been practiced since long time and is commercially successful. Amylases convert the water insoluble starches, used during sizing operation for enhancing the performance of the warp yarns, into water soluble products which are removed during subsequent washing. The use of enzymes for desizing is quite safe for the cotton substrates and do not cause any detrimental effect on the cotton cellulose unlike …
