The formation and turnover of soil organic carbon (C), the largest terrestrial C pool, is strongly impacted by ultimate source that C: leaves, wood, roots, root exudates. quantity quality these inputs determined identity plants involved. Yet substantial uncertainty surrounds complex relationships among plant traits C, precluding efforts to maximize whole-ecosystem uptake in nature-based climate...

the article provides a critical assessment of the more recent literature that relies on theoretical frameworks such as post modernism and globalization to deal with national identity, ethnicity and cultural mobility. explaining sensitive and complicated issues such as identity requires the extensive use of the native historical, cultural and sociological sources related to the iranian experienc...

this investigation postulatesvygotsky’s (1978) concept of zone of proximal development (zpd) and his related “scaffolding” metaphor as well as norton’s (2006) principles of sociocultural identity as its theoretical foundation.thisresearchintends to scrutinizethe socioculturally-oriented mediationalmechanisms utilized in student-student and student-teacher collaborationsin an iranian efl writing...

identity orientations refer to the relative importance that individuals place on various identity attributes or characteristics such as race, religion, culture and language when constructing their self-definitions (chew, 2007; cheek, 1989). accordingly, the present study aims at identifying the impact of identity aspects on the iranian learners' english language achievements at shiraz universit...

Key agreement allows multi-parties exchanging public information to create a common secret key that is known only to those entities over an insecure network. In recent years, several identity-based authenticated key agreement protocols have been proposed. In this study, we analyze three identity-based tripartite authenticated key agreement protocols. After the analysis, we found that these prot...

the present study was aimed at examining concerns about the social effects of efl learning, a challenging area of research which has not been discussed sufficiently. it tried to investigate the relationship between efl learning and national identity. in addition, attempt was made to find a relationship between language motivation types and national identity. furthermore, the role of two demogra...

Public-key infrastructures (PKIs) that support both identity certificates and access control (e.g., attribute, delegation) certificates are increasingly common. We argue that these PKIs must also support revocation and review policies that are typical of more traditional access control systems; e.g., selective and transitive certificate revocation, and per-object access review. Further, we show...

Antiserum prepared in rabbits against Bacteroides fragilis showed numerous bands when reacted with B. fragilis antigen in Ouchterlony plates. This antiserum also reacted with Bacteroides thetaiotaomicron and showed one band of apparent identity with B. fragilis. The band of identity common for both organisms was lost if the antigen was heated at 80 degrees C for 30 min. Antisera prepared agains...

At Crypto-87 conference, we proposed identity-based key distribution systems for generating a common secret conference key for two or more users. Protocols were shown for three configurations: a ring, a complete graph, and a star. Yacobi has made an impersonation attack on the protocols for the complete graph and star networks. This paper proposes improved identity-based key distribution protoc...
