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...

the revival of chalcolithic sites have a particular importance in tracing the settlement patterns of the region, in the aegis of special biological features and replacing in environmental elements. by depicting the special features, the characteristics of plain of hamedan and its strength in northern plain (kaboodarhang) must be hinted. this plain is determined as a joint fund between central z...

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...

BACKGROUND In December 2012, Australia introduced world-first legislation mandating plain packaging for all tobacco products. To date, there is very little evidence on youth responses to the changed packs. AIM To assess attitudes towards, and responses to, tobacco plain packs preimplementation and postimplementation. METHODS The Tobacco Promotion Impact Study (TPIS) was a yearly cross-secti...

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...

INTRODUCTION INTRODUCTION The diagnostic value of colour Doppler sonography for the detection of blood flow in intussusception is questionable. The purpose of this study was to evaluate plain radiography in the assessment of vascular compromise in children with intussusception. MATERIAL AND METHODS The hospital notes of 1,119 paediatric cases of intussusception who presented between Januar...

OBJECTIVE To review the current literature around the potential impact, effectiveness and perceptions of plain packaging in low income settings. METHOD A systematic review of the literature. DATA SOURCES 9 databases (PubMed, Global Health, Social Policy and Practice, Applied Social Sciences Index and Abstracts (ASSIA), CINAHL, PsycINFO, British Library for Development Studies (BLDS), Global...

Recent studies on perceptual learning have indicated that listeners use intermediate units between the acoustic input and lexical representations of words. The same paradigm may also reveal the nature of these intermediate units based on patterns of generalization of learning. We here test whether learning generalizes to other units of the same underlying or surface representation. This was ach...

In this paper, a simple and robust color image encryption algorithm based on highdimensional chaotic maps is proposed. The algorithm employs a 3D Arnold transform to perform inter-component shuffling of plain-image, while a 2D hyper-chaotic map is used to confuse the relationship between the encrypted image and plain-image. The control parameters of Arnold transform are extracted from pending p...
