In February 2008 the European Academy of Periodontology (EAP), a standing committee of the European Federation of Periodontology (EFP), invited seventy-three researchers and clinical experts from Europe and overseas for a 5-day consensus meeting on “Contemporary Periodontics.” Five working sessions covered the topics “Innovations in Periodontal Practice,” “Periodontal Tissue Engineering and Reg...

Introduction: The relationship between fossil fuel energy resources and environmental degradation has been quantified from theoretical empirical perspectives. However, none of these studies considered the conditioning role played by institutions in nexus, especially for BRICS countries. Therefore, current study examines moderating institutional quality using annual data 1996–2018 Method: employ...

Detailed molecular dynamics simulations of an acid-base reaction have been the subject of extensive investigations. Here we report the excited state proton transfer dynamics of pyranine (8-hydroxypyrene-1,3,6-trisulfonic acid, HPTS) in acetate buffer by time-resolved fluorescence (TF) and quantum mechanical/effective fragment potential molecular dynamics (QM/EFP-MD) simulations. High time resol...

A hybrid quantum mechanics/molecular mechanics (QM/MM) method for the electronic excited states has been developed. The equation-of-motion coupled cluster with single and double excitations method (EOM-CCSD) is used for the QM region, while the effective fragment potential (EFP) method describes a MM part. The EFP method overcomes the most significant limitation of QM/MM by replacing empirical ...

in order to evaluate plant density and cultivar effects on rate and process of grain filling, yield and yield components of three dry bean cultivars a factorial experiment (using r.c.b. design) was conducted in 1386 at agricultural and natural research center of east azarbaijan (tabriz). three cultivars (khomeyn, g-14088 and 11816) were planted at four densities (14, 20, 30 and 60 plants/m2) in...
