Cellulose-silica composite fiber samples have been successfully synthesized using cellulose solution, tetraethoxysilane, and NH3•H2O in ethanol/water mixed solvents at room temperature for 24 h. The cellulose solution was previously prepared by the dissolution of microcrystalline cellulose in a solvent mixture of N,N-dimethylacetamide (DMAc)/lithium chloride (LiCl). The effect of the tetraethox...

Objectives This study aimed to introduce the use of laser-induced breakdown spectroscopy (LIBS) for evaluation of the mineral content of root canal dentin, and to assess whether a correlation exists between LIBS and scanning electron microscopy/energy dispersive spectroscopy (SEM/EDS) methods by comparing the effects of irrigation solutions on the mineral content change of root canal dentin. ...

Abstract In this study, graphene oxide (GO), iron modified clinoptilolite (FeZ), and composites of GO-FeZ (GOFeZA GOFeZB) were synthesized characterized using SEM, EDS, XRF, FTIR, pH pzc . The arsenate uptake on GOFeZA GOFeZB was examined by both kinetic column studies. adsorption capacity increases with the increase initial concentration at equilibrium for composites. At 450 μg/L, 557.86 554.6...

مداخل يعسوت رامعم ميمصت " ةجاحلا بسح ةددعتم طئاسو " ABSTRACT in this paper we develop a Vhdlbased scalable architecture of a multimedia on demand server model. Te three server subsystems are:the control subsystem, the communication subsystem and the storage subsystem are modeled. The communication subsystem is designed as an interconnection network with meshed-pipe structure and delivers packe...

This study is concerned with recent analyses of seven marble statues from the imperial cycle Augusteum Rusellae, in south Tuscany, Italy. The sculptures represent deified couple Augustus and Livia, Livilla, Claudius, an anonymous young girl a headless cuirassed emperor (maybe Domitian). In addition, fragment leg, another statue, was also considered. All them are preserved city Grosseto, Maremma...

This work aims to investigate the influence of temperature and chemical impregnation in textural morphological composition bio-adsorbent bio-adsorption via thermal cracking seeds açaí. The experiments were carried out at 400 °C 450 using a pilot scale reactor. efficiency organic process was calculated terms liquid solid products selected with NaOH, mainly that had greater product conversion. el...

Phosphorus depletion represents a significant problem. Ash of incinerated biological sewage sludge (BSS) contains P, but the presence heavy metals (e.g., Fe and Al) is main issue. Based on chemical characterization by SEM-EDS, ED-XRF ICP-OES techniques, characteristics P content bottom ash (BA) fly (FA) BSS were very similar. On BA, extraction carried out in counter- current with an S:L ratio 1...

Abstract Valvasor's library is a unique example of Seventeenth century personal library, including over 7300 prints and 1530 books. Today, it kept in the Metropolitan Library Zagreb Archdiocese which part Croatian State Archives. In this study, we analysed selection papers from collection ( VC ) unknown origin composition. We used dual approach, combining results analyses two sets samples to fi...
