    Atherogenesis has been traditionally viewed as a metabolic disease representing arterial obstruction by fatty deposits in its wall. Today, it is believed that atherogenesis involves highly specific biochemical and molecular responses with constant interactions between various cellular players. Despite the presence of inflammatory reaction in each and every step of atherosclerosis from its inception to terminal manifestation, the cause–effect relationship of these 2 processes remains unclear. In this article, we have attempted to review the role of inflammation in the development of atherosclerosis and in its major complication—coronary heart disease

    The present investigation is mainly focused on studying the complete stress-strain characteristics of geopolymer concrete (GPC) with different fine aggregate blending. In this study, granite fines (GF) were used as a partial replacement of fine aggregate. Sand and GF were used as fine aggregates blended in different proportions (100:0, 80:20, 60:40 and 40:60) (sand:GF) by weight. GPC cylindrical specimens were tested under compression and the results obtained from the tested data were analyzed to determine the compressive strength (fcm), stress-strain relationship, peak strain (εp), linearity of the stress-strain curve, ultimate strain (εu), various modulus of elasticity (MOE) values, and Poisson’s ratio (μ) of GPC after a period of 7, 28 and 90 days respectively. From the results, it is concluded that the increasing trend was observed in the properties till 40% (60:40) of GF replacement and then these values were decreased. So, optimum fine aggregate was blended at 60:40. Based on the test results, new models were developed for predicting the stress-strain characteristics of GPC under compression by using regression analysis. The results of proposed models were then compared with the experimental values and the predicted equations by various codes and past research.

    This paper analyses the structural behavior of reinforced self-compacting concrete beams under two-point loading. A total number of five beams were cast with varying quantities of alccofine (i.e., 0, 5, 10, and 15%) and constant dosage of fly ash (i.e., 25%) and tested for examining the load-deflection curves and ultimate moment carrying capacity of reinforced self-compacting concrete beams. From obtained experimental results, it was found that the load-carrying capacity was increased when the beam with the addition of alccofine and fly ash is compared with the normal concrete beam. The experimental obtained ultimate strength values were compared with theoretically predicted values using IS 456-2000, ACI 318-11, and CSA A23.3-04 codes
