Studies on vegetation changes of rangelands under grazed and non-grazedconditions are of great importance in the range management planning programs. To determinethe change process of vegetation, this study was performed in Inche Shorezar site of Golestanprovince for nine years (1997-2005). The vegetation parameters were measured every year inseveral fixed plots inside and adjacent of exclosures...

OBJECTIVE We sought to determine the clinical phenotype of adolescent/adult patients with cystic fibrosis, according to heterozygosity or homozygosity for cystic fibrosis transmembrane regulator (CFTR) deltaF508 mutation, and to analyze their characteristics according to glucose tolerance status. RESEARCH DESIGN AND METHODS A total of 76 cystic fibrosis patients with CFTR deltaF508 mutation (...

We present an undecidability result for the verification of security protocols. Since the perfect cryptography assumption is unrealistic for cryptographic primitives with visible algebraic properties, several recent works relax this assumption, allowing the intruder to exploit these properties. We are interested in the Abelian groups theory in combination with the homomorphism axiom. We show th...

fluoride is one of the most important elements in the composition of teeth and bones. this element can enter the body via different ways. however, drinking water is the most important way to receive fluoride by a lot of people. an increase in fluoride level in the body causes dental fluorosis and its absence leads to teeth decay. standard rate of fluoride in drinking water is determined by the ...

A seamless and tough interface to integrate incompatible/immiscible soft materials is highly desired for flexible/wearable electronics many devices with multi-layer structures. Here, a surfactant-mediated interfacial chemistry introduced achieve interfaces in structures, an ultra-high toughness up ≈1300 J m−2 the architectural gel hybrid (AGH). The reversible noncovalent interactions efficientl...
