Sponge iron (DRI) due to the high surface area, often shows a high tendency to re-oxidation and at some cases spontaneous combustion (autoignition). In this work, re-oxidation behavior and autoignition of sponge iron, produced from different types of iron ore has been investigated. Isothermal and non-isothermal re-oxidation experiments were carried out on each type of DRI and their autoignition...

Ginseng is now used worldwide as a traditional Oriental medicine. Ginsenosides, alsoknown as ginseng saponins, are responsible for most pharmacological efficacies of ginseng.This work aimed to assess the novel skin anti-photoaging potential of ginsenoside Re (Re), aprotopanaxatriol-type ginsenoside, by analyzing reactive oxygen species (ROS), pro-matrixmetalloproteinase-2 (proMMP-2) and -9 (pro...

  Background: The Rosemary extract (RE) possesses various antioxidant, cytoprotective and cognition-improving bioactivities. In this study, we postulated which doses of RE have a more effect on the hippocampus of middle-aged rats.   Methods : In this experimental study, thirty-two middle-aged male Wistar rats were fed by different doses (50,100 and 200 mg/kg/day) of RE (containing 40% carnosic ...

In a proxy re-encryption scheme a semi-trusted proxy converts a ciphertext for Alice into a ciphertext for Bob without seeing the underlying plaintext. A number of solutions have been proposed in the public-key setting. In this paper, we address the problem of Identity-Based proxy re-encryption, where ciphertexts are transformed from one identity to another. Our schemes are compatible with curr...

introduction:ventilator- associated pneumonia(vap),as defined by the centers for disease control and prevention (cdc),is a pneumonia that occurs in a patient receiving mechanical ventilation that develops 48 hours or more after initiation of ventilation.re-intubation which occur within 72 hours of planned extubation may effect vap incidence.the aim of this study was to determine vap incidence i...

An identity-based proxy re-encryption scheme allows the semi-trusted proxy to convert ciphertexts encrypted under Alice’s public identity into the ciphertexts encrypted under Bob’s public identity. The proxy cannot learn any information of the underlying message. As in other delegation schemes, identity-based proxy re-encryption scheme should be secure against collusion, especially of the proxy...

Meal machine, experimental laboratory, status symbol, domestic prison, or the creative and spiritual heart of the home? Over the course of the past century no other room has been the focus of such intensive aesthetic and technological innovation, or as loaded with cultural significance. Kitchen design has been both a central concern of modernism and fundamental to our concept of modern life (Mo...
