in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
though the fields of regenerative dentistry and tissue engineering have undergone significant advancements, yet its application to the field of implant-dentistry is lacking; in the sense that presently the implants are being placed with the aim of attaining osseointegration without giving consideration to the regeneration of periodontium around the implant. the following article reveals the cli...
There are several restorative alternatives for replacing a missing anterior tooth. The single implant-supported crown is among the best restorative options under certain biological and biomechanical condition like sufficient bone quantity, condition and morphology of the periodontium, integrity of natural and restored teeth. The long-term success of an implant supported crown depends upon the h...
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

Several restorative alternatives for replacing a missing anterior tooth are now in use. The single implant-supported crown is one of the best restorative options, under certain biological and biomechanical conditions – such as sufficient bone quantity, condition and morphology of the periodontium, integrity of the natural and restored teeth. The long-term success of an implant depends upon the ...
O ral implants are valuable tools in the prosthetic reconstruction of partially edentulous jaws. These reconstructions may be performed in two principally different ways: (1) free-standing implant-supported bridges (2) tooth-implant-supported bridges. The advantages and drawbacks of splinting teeth and implants have been discussed in the literature. The tooth-implant connections were early ques...
Abstract The implant-supported removable partial dentures should be an alternative to conventional removable partial dentures and implant-supported fixed partial prostheses when the implant’s insertion is confined by bone height and thickness. Placing a single implant in the posterior region would modify the Kennedy Class II configuration to a Kennedy Class III and increase the stability a...
abstract the present study investigated the effects of task types and involvement load hypothesis on incidental learning of 10 target words (tws) in junior high schools (jhss) in givi, ardabil. the tasks deployed in this study were two input-based tasks (reading plus dictionary use with an involvement index of 3, and reading plus gap-fill task with an involvement index of 2), and one output-ba...
this thesis attempts to investigate the effects of prelistening activities on enhancing iranian efl learners` listening comprehension. the present study investigated ways in which learners` background knowledge could be activated in order to enhance their l2 listening comprehension by limiting the number of possible text interpretations prior to listening. the experiments conducted in this stud...
