This research is a part of a wide range investigation on the use of flue gas desulphurisation (FGD) in construction applications. It reports some results on the porosity and pore size distribution of cement paste containing varying amounts of fly ash-gypsum blends as partial replacement of cement. The cement was replaced with 25% of different blends of fly ash and gypsum. The gypsum content ran...

Segmentation procedures of concrete microscopic images and standard test methods devoted to the spacing factor calculation for freeze-thaw resistance assessment are time-consuming skill-dependent. Moreover, manual color treatment careful image examination often needed. Within past few years, Convolutional neural networks (CNN) have proved unpreceded performances in segmentation object detection...

Revascularization of immature teeth with necrotic pulps traditionally involves the use of triple antibiotic paste, which may sometimes lead to undesirable complications. The objective of this study was to assess tissue repair in immature dog teeth with apical periodontitis subjected to revascularization, comparing two different pastes used for root canal disinfection. Apical periodontitis was i...

Currently, the photovoltaic industry is focusing on development of low-cost modules with increased efficiency by altering structure module. In this study, a PET electrode sheet module was fabricated using cell/module integration. The connecting (stacked busbar-less solar cell) to electrodes via lamination process. flat and grooved films. which A-stage paste applied, slipped disconnected. contra...

The aim of this case report was to evaluate the potential of preformed titanium foil (PTF) as membrane, used together with a mouldable allograft paste, for guided bone regeneration in a case of severe mandibular posterior atrophy involving the alveolar nerve. In order to create a rigid barrier to the competitive growth of soft tissues and a stable volume for the colonization of the osteoprogeni...

Magneto-induced rheology control is beneficial to overcome the opposing property requirements in different construction processes. The viscoelastic properties of paste medium have great effects on movement and distribution magnetic particles when applying an external field thus degree rheological response. In present research, effect (total) solid volume fraction ϕT magnetorheological (MR) resp...

Flash sintering has been investigated as a modern sintering method through examining the effect of processing parameters such as current density, temperature, and contact paste on the flash sintered 8YSZ characteristic. 95% of theoretical density was achieved at 800°С in 30sec with a field intensity of 100V.cm-1 and a current density of 160mA.mm-2. Such relative density in conventional sinterin...

BACKGROUND The purpose of this study was to evaluate the effect of dehydration of resin-modified glass ionomer powder/liquid system, resin-modified glass ionomer paste/paste luting cements in three different quantities and to compare them with a conventional glass ionomer luting cement using confocal laser scanning microscope. MATERIALS AND METHODS A conventional glass ionomer (Group I), a re...

OBJECTIVES To investigate in vitro the effect of MI Paste, MI Paste Plus and 2800ppm fluoride (F) toothpaste (TP) on the remineralisation of enamel subsurface lesions and to compare these to the effect of 1450ppm and 0ppm F toothpastes. METHODS Enamel subsurface lesions were created in bovine enamel slabs (n=120) which were assigned randomly to five groups; (1) 0ppm F TP, (2) 1450ppm F TP, (3...
