a mild, green and highly efficient route for regio-selective amination of oxiranes was developed via incorporation of mn(ii), fe(ii), co(ii), ni(ii), cu(ii) and zn(ii) cations onto the surface of hydroxyapatite-encapsulated γ-fe2o3 nanoparticles (γ-fe2o3@hap). among six magnetically recoverable catalytic systems denoted as [γ-fe2o3@hap-mii], the catalyst in which m designated as fe(ii) showed t...

polydimethylsiloxane (pdms) has been synthesized by ring-opening polymerization of octamethylcyclotetrasiloxane (d4) in microemulsion with acidic catalyst. the structure and properties of microemulsion were characterized by transmission electron microscopy (tem), fourier transform infrared spectroscopy (ft-ir), photo correlation spectroscopy (pcs). the effect of the variation in ph value, amoun...

abnormal elongation of the mandibular coronoid process is rare and its etiology is not yet elucidated. the aim of this report is to demonstrate and discuss the relationship between elongated mandibular coronoid process and limitation of mouth opening with cone beam computed tomography. although the clinical characteristic of elongation of the coronoid process is mandibular limitation, in this r...

The Ambient Calculus and the Safe Ambient Calculus have been recently successfully proposed as models for the Web. They are based on the notions of ambient movement and ambient opening. Different type disciplines have been devised for them in order to avoid un-wanted behaviours of processes. In the present paper we propose a type discipline for safe mobile ambi-ents which is essentially motivat...

In many cases, government data is still ‘locked’ in several ‘data silos’, even within the boundaries of a single (inter-)national public organization with disparate and distributed organizational units and departments spread across multiple sites. Opening data and enabling its unified querying from a single site in an efficient and effective way is a semantic application integration and open go...

The development of Web Services has transformed the World Wide Web into a more application-aware information portal. The various standards ensure that Web Services are interpretable and extensible, opening up possibilities for simple services to be combined to build complex ones. The Semantic Web presents a new mechanism for users and software agents to discover, describe, invoke, compose and m...

Additively to the emergence of wireless networking, high technology and reliability of mobile devices have enabled the widespread use of mobile computing. Currently, this last is in vogue and booming. Today, the combination of mobile networks with Web Services called “Mobile Web Service”, opening a promising horizon for the economy. They offer (Mobile Web Service) new personalized services to c...

Salivary megaduct with stricture is characterized by recurrent pain, cheek and parotid swelling. We report on a case of circular web type fibrotic stenosis accompanying large found sialendoscopy. Although, sialendoscopy enabled minimally invasive diagnosis treatment stenotic lesion the Stensen’s duct, bougination not effective for severe stenosis. Transoral sialodochoplasty assisted can be an a...

In this paper, we present an approach and a visual tool, called HWrap (Handle Based Wrapper), for creating web wrappers to extract data records from web pages. In our approach, we mainly rely on the visible page content to identify data regions on a web page. In our extraction algorithm, we inspired by the way a human user scans the page content for specific data. In particular, we use text fea...

To study the performance of UHPFRC continuous deep beams with openings, experimental and numerical investigations have been carried out. The test program included seven in addition to one similar solid beam. variables were ratio transverse reinforcement position, height, width opening. results showed that failure mode two-span depends mainly on position size opening shear span. occurs diagonal ...
