چکیده
Various mo]ccules may tLct as an ttcceptor. but lcvans, hexoses and water are highly rcactive. Most studies on ]evansucrases havc been done in Ba('iUus subtilis. Chambert c,t ai,"'2i have invcstigated the mechanism of the transfructosylation proccss. Petit-Glatron et al.]) have characterized a mucromo]ecular inactive form of leN,ansucrase. LcBrun et aL4} prescnted the tcrtiary structure or the en7lrme. The gene sa('B, which codes for the exoenzyme [evunsucrase of B. suhtiiis, has been cloned by Gay et ai.,S]

Estimating the Mechanical Properties of Travertine Building Stones Due to Salt Crystallization Using Multivariate Regression Analysis
Salt crystallization is one of the most powerful weathering agents that may cause a rapid change in the mechanical properties of stones, and thus limit their durability. Consequently, determining the mechanical properties of stones due to salt crystallization is important for natural building stones used in marine environmental and mild climatic conditions, which expose excessive salt crys...
متن کاملEstimating the durability of building stones against Salt crystallization: considering the physical properties and strength characteristics
Salt crystallization is one of the most important weathering agents and may limit the durability of building stones. Salt crystallization induces stresses inside the pores of stones. Consequently, stone durability is closely related to its physical properties and strength. The purpose of this study was to propose a statistical model for estimating stone durability against salt crystallization c...
متن کاملThe Crystallization Effect on the Optical Properties of Oxyfluoride Glass-Ceramics Containing CaF2 Nanocrystals Doped with Y3+ Ions
In the present study, the oxyfluoride glasses of SiO2-Al2O3-CaF2 system containing different amounts of Y3+ ions were prepared through the convenient melting method. The crystallization temperatures and size of the CaF2 nanocrystals were obtained from DTA curves and XRD patterns, respectively. As a consequence, the optimum amount...
