Strength Characterstics of Fiber Reinforced Geopolymer Concrete for Rigid Pavement Applications

The present investigation focuses on the design and development of blended fiber reinforced geopolymer concrete for rigid pavement applications. The concrete that is manufactured using alkali activation materials have the potential to replace the OPC as well as the problems that are associated with it. In this investigation, nbsp;the strength characteristics of GPC for rigid pavement applications are studied and reported. The alkaline initiator solution utilized to activate the GPC binder was NaOH solution of 12Molar concentration, which is mixed in liquid Na2SiO3.The study was divided into two phases and in the first phase of study, the usage of industry residuals like fly ash and GGBS with replacement levels of (50%+50%), (60%+40%) and (40%+60) were used as primary ingredients to prepare GPC of M45 grade and the compressive strength results were noted and in the second phase of study, the strength characteristics of glass fiber reinforced GPC was studied. The test results reported that the prepared GPC is satisfying the strength requirements of rigid pavement applications

Effect of dietary milk cream and egg yolk fat on serum and liver lipid profile in rats

Influence of dietary fat from milk and egg yolk on serum and liver lipid profile was studied in rats. Rats fed milk fat at 5% level for 8 weeks showed a 17% decrease in serum cholesterol and 31% decrease in triacylglycerol compared to the control group of rats fed groundnut oil (GNO). Liver cholesterol was decreased by 20% in the milk fed group. There was no difference in serum cholesterol concentration of rats fed egg yolk compared to the control animals. However, triacylglycerol and phospholipids in serum of rats fed egg yolk were decreased by 20 and 24%, respectively. In another set of experiments animals were rendered hypercholesterolemic by feeding a diet containing 0.5% cholesterol. Addition of milk fat in the diet decreased serum and liver cholesterol by 11 and 17%, respectively, compared to rats fed on a control diet. Similarly, triacylglycerols were decreased by 23 and 8%, respectively, in serum and liver of animals give

Phototoxicity of some novel porphyrin hybrids against the human leukemic cell line TF-1

Photodynamic induced cytotoxicity by porphyrin-DNA cross linker/intercalator hybrid diads and triads has been studied on the human leukemic cell line TF-1. Cells were incubated for 1 to 4 h with these new photosensitizers and irradiated with white light. Cell survival was assessed by the propidium iodide staining, using flow cytometry analysis. A comparison of the dark and light cell survival factor values suggests that irradiation has a significant effect on the toxicity at low concentrations for the porphyrin-chlorambucil diad and to a lesser extent at high concentrations for the porphyrin-acridone diad, the porphyrin-acridine diad and the porphyrin-cholic acid-chlorambucil triad. While the intrinsic antileukemic (via DNA cross-linking) activity of the chlorambucil moiety and the structural details may be responsible for the photoenhancement of the toxicity, the presence of acridine or acridone which are avid intercalators of DNA, is responsible for a similar effect seen for diads
