Non-Linear Dynamic Analysis of High-Rise Flat Slab Structure with Various Lateral Load Resisting System: Indian Scenario
Abstract: In this technological era, the construction of high-rise flat slab structure is increasing everywhere, due to its major advantages over a conventional beam slab structure. Due to the poor performance of high-rise flat slab structure in higher seismic zones, IS 1893 (Part 1): 2016 discourages the use of flat slab structure in higher seismic zones. The use of high-rise flat slab structure in high seismic region is a risk, because …

The Effect of Shear Bond Strengths and the Mode of Bond Failure in Metal and Ceramic Brackets Bonded with Fluoride Releasing Composites: An in vitro Comparative Study
Abstract: One of the standard measures in the prevention of enamel demineralization is the use of Fluoride. Fixed orthodontic attachments act as a retentive area for plaque accumulation that leads to development of white spot lesions (WSLs). Incorporation of fluoride into adhesives for bracket bonding inhibitsdemineralization during fixed orthodontic treatment. However, the addition of fluoride into orthodontic adhesives may affect the mechanical properties such asshear bond strength (SBS). The present study …

To Study the Effects of Butler’s Neuromobilisation and Proprioceptive Neuromuscular Facilitation on Lower Limb Sensory Deficits in Chronic Stroke: A Comparative Study
Abstract: Stroke is a leading cause of functional impairments worldwide. Deficits in somatic sensations (body senses such as; touch, temperature, pain and proprioception) after stroke are common with high prevalence rates. Sensory deficits have been shown to predict poor functional outcome after stroke, including increased length of hospitalization, lower levels of discharge home, lower numbers of home discharges, and increased mortality rates. The objective of the study was to compare the …

The Effects of Stress on Memory
Abstract: Stress throws the organisms’ body out of homeostatic balance. The physiological stress response acts by activation of two systems to balance the disturbance: the SNS and the HPA-axis. Stress has enhancing and impairing effects on memory processes: encoding, consolidation, and retrieval. These opposite effects may be explained if the different time courses of stress hormone, in particular catecholamine and GC actions are taken into account. This review will access the …
