over the last two decades there have been numerous reports from different seismically active regions of the world that thermal infrared (tir) anomalies can be identified around the epicentral areas before major earthquakes [e.g. (tronin et al., 2002)]. the tir anomalies reportedly appear as early as 14 to 7 days before the seismic events and affect areas as large as 1000s to 100,000s km2 in siz...

OBJECTIVE To examine the consumption of plain water among children in France and compare total water intakes with guidelines issued by the European Food Safety Authority (EFSA). DESIGN Nationally representative data were used to assess food, beverage and water consumption by sex, age group (4-8 years, 9-13 years), income-to-poverty ratio, eating occasion and location. Beverages were classifie...

BACKGROUND Aspirin is associated with gastrointestinal side effects such as gastric ulcers, gastric bleeding and dyspepsia. High-dose effervescent calcium carbasalate (ECC), a buffered formulation of aspirin, is associated with reduced gastric toxicity compared with plain aspirin in healthy volunteers, but at lower cardiovascular doses no beneficial effects were observed. AIM To compare the p...

in this research 220 rhizobial bacteria were isolated from two lentil dryland farming flat plains of moghan and koohin. they were then tested in vivo as well as in vitro to make assurance of 184 purified strains of rhizobium leguminosarum biovar vicial (lentil). btb +yma culture media with different levels of salinity through nacl (10, 20,30,40,50ds/m) application were used in salinity toleranc...

Across the entire distribution of a species, populations may have variable responses to environmental perturbations. Many bat species experience mortality in large portions of their range during hibernation and along migratory paths to and from wintering grounds, from White-nose syndrome (WNS) and wind energy development, respectively. In some areas, warm temperatures may allow bats to remain a...

Recently, a novel image encryption scheme based on improved hyperchaotic sequences was proposed. A pseudorandom number sequence, generated by a hyper-chaos system, is used to determine two involved encryption functions, bitwise exclusive or (XOR) operation and modulo addition. It was reported that the scheme can be broken with some pairs of chosen plain-images and the corresponding cipher-image...

In polyalphabetic substitution the plain text’s letters are enciphered differently according to their position. The name polyalphabetic suggests that there are more than one key so we have used two keys combination instead of just one, in order to produce the cipher text. We can also use three or more keys to make the enciphering process more complicated. In this paper have produced ASCII Codes...
