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.

BACKGROUND & OBJECTIVES Visceral leishmaniasis (VL) is a major vector-borne disease in Iran. A focus of VL is present in Shahreza county, Isfahan province, central Iran. The main objective of this study was to determine the probable vectors in this area. METHODS Sand flies were collected biweekly using sticky paper traps, CDC light-traps, and aspirators from outdoors as well as indoors. All f...

In this work, two clay-based composites are prepared for the adsorptive removal of the chloride ions from aqueous solutions. These composites are characterized through Fourier transform-infrared spectroscopy, scanning electron microscopy, X-ray fluorescence spectroscopy, and X-ray diffraction analysis. The effects of different parameters such as the contact time, amount of adsorbent, chlo...

Although caviar is the most significant and famous fishery product of Iran, in recent years the country has gained a lot of experience and had some significant success with other fishery and aquaculture products. Iranian fisheries and aquaculture production reached 522,000 metric tons in 2005, of which 75% originated from capture fishery and 25% from aquaculture activities. Various fishery and ...

BACKGROUND Zoonotic cutaneous leishmaniasis (ZCL) is an expanding disease and public health problem in Iran. In the current study, natural Leishmania infection rate and seasonal fluctuation of the infection in Rhombomys opimus population of a hyperendemic focus of ZCL in Iran was investigated. METHODS The study was conducted from October 2006 to October 2008 in Esfahan Province, central part ...

Abstract Environmental DNA (eDNA) is a convenient biodiversity monitoring tool, and many studies have focused on river coastal areas, while deep‐water oceanic surveys are rare. However, using eDNA techniques to learn about communities may also be useful approach. We tested methods enhance ocean collections adding four different materials (sediment, diatomite, zirconia bead, molecular sieve) in ...

The ability of dietary hydrated sodium calcium aluminosilicate (HSCAS), diatomite and activated charcoal (AC) in reducing the detrimental effects of aflatoxin B1 (AFB1) in broiler diets was evaluated. Adsorbents were supplemented at 2.5 g/kg to the diets containing 0, 40 or 80 μg AFB1/kg feed. One hundred and eighty Ross 308, day-old male broilers were assigned to 12 treatments for 42 days. AFB...

The comprehensive utilization of low-grade diatomite resources and the effective treatment printing dyeing wastewater have attracted widespread attention. combined scrubbing-magnetic separation-acid leaching-roasting process was used to increase SiO2 content from 59.22% 86.93%, reduce Al2O3 18.32% 6.75%, Fe2O3 6.85% 1.24% in Heilongjiang, China. TiO2/g-C3N4/diatomite nanocomposite prepared by a...
