This paper introduces the concept of a dynamic key infrastructure for Grid. It utilises the properties of Identity-based Cryptography (IBC) to simplify key management techniques used in current Public Key Infrastructure (PKI) settings for Grid. This approach can offer greater simplicity, flexibility, and enhanced computation trade-offs.

According to WHO reports, the prevalence of diabetes is 10.3% in Iran with an approximate male to female ratio of 1:1 (1). In this regard a national survey in Iran illustrated the diabetes prevalence is 7.7% in adults (25–65 years) (2). However, another study i...

The evolution of building codes typically produce design provisions that are expected to create safer and more accurate designs. We as engineers expect building codes to advance the state of the art with each successive edition. The 2009 International Building Code (IBC) and the Building Code Requirements for Structural Concrete (ACI 318-08) have significant revisions affecting the design of ti...

Population of Iran as a Middle Eastern country with its population growth rate of about 1.3% has passed 80 million in 2016.

BACKGROUND Obesity is a serious worldwide medical condition, considered by some researchers as one of the most serious public health problems of the 21st century. The main objective of this study was to assess the quantity and quality of obesity-related research from Arab countries and compare it with that from non-Arab Middle Eastern countries. METHODS Original scientific articles or reviews...

In the past decades, cardiovascular diseases were the most common causes of death around the world and in Iran (1, 2). Various factors play an important role in the incidence of CVD; such as environmental, personal as well as lifestyle. We studied the geographical distribution of 19142 CVD deaths f r o m 2004 -2010 in South Khorasan. The mean age of the deceased was 59.3±28.9 years. 28.5% death...
