This investigation aims at determining the microhardness value of the hybrid direct/indirect composite resins submitted to conventional light curing and post-cured using two different methods, a light source from a laboratory light curing unit and a conventional oven heating, and the obtained results were compare to an indirect composite resin. A hybrid direct/indirect composite resin (Filtek P...

To address the problem of chloride ion transport in cement concrete marine environment, this study investigates effect metakaolin dosage on diffusion resistance mortar and its mechanism by testing binding capacity microstructure under coupling chlorine salt-sulfate-carbonation multiple factors. The results show that sulfate or carbonation reduces to some extent compared with single salt attack,...

the organo-metal salt of aluminum triacrylate (alta) with a general formula of (ch2=chcoo)3al was  synthesized  as  a  reactive  fller  for  elastomers through a two-step synthetic procedure. fourier transform-infrared spectroscopy (ftir), dsc and dta were employed for alta analysis and to study its cure characteristics. in this research, two composites based on ethylene propylene diene monomer...

The studies concern the effect of addition acid whey in combination with sodium ascorbate on selected parameters related to proteolysis uncured dry-fermented sausages. Four sausage samples (with different additives: curing mixture (C); sea salt (S); and liquid (SAW); salt, (SAWA)) were taken at day 0, 7, 14 21 ripening assess basic physicochemical properties, thiobarbituric acid-reactive substa...

Dried salted fish is a traditional dry-cured that sprinkled with salt before the curing process. With unique flavor as well diverse varieties, popular among consumers worldwide. The presence of various microbial communities during process leads to numerous metabolic reactions, especially lipid oxidation and protein degradation, which influence formation substances. However, industrial curing, q...

Tannery wastewater usually contains a high salinity due to the use of sodium chloride (NaCl) in curing and pickling. Although some no-pickle tanning and salt-free pickling technologies were developed, few of them have been widely used due to relatively poor mechanical and bulk properties of the resultant leather. Therefore, the role of NaCl in pickling and tanning should be elucidated in the fi...

This paper compares the alkali-activated fly ash (AAFA) manufactured with thermal oven curing and pulsed microwave curing methods. Fly ash activated by 8M NaOH solution at a liquid to solid ratio of 0.3 was cured by thermal oven at 85°C and domestic microwave oven, respectively. Apart from compressive strength test, the temperature profiles of AAFA samples were captured by thermal camera. React...

Concrete is an essential building material which is widely used in construction industry all over the world due to its compressible strength. Curing of concrete plays a vital role in durability and other performance necessities. Improper curing can affect the concrete performance and durability easily. When areas like scarcity of water, structures is not accessible by humans external curing can...

OBJECTIVE The aim of this study was to determine the effects of light intensity and type of light unit (quartztungsten-halogen [QTH] or light-emitting diode [LED]) on the hardening of various resin cements and a resin composite restorative. METHODS Disk specimens were prepared from 4 dual-cured resin cements (Variolink II, Calibra, Nexus 2 and RelyX ARC). Two QTH light-curing units (Visilux 2...
