The aim of this study was to compare polymerization lamps of various technologies (halogen, high performance halogen, xenon, i.e. plasma arc, as well as diode lamps) to determine the degree of polymerization of composite probes using Fourier-transform infrared (FTIR) spectroscopy. To observe the light-induced curing reaction under a bracket, an attenuated total reflection (ATR)-FTIR was used. T...

when geotechnical engineers are faced with cohesive clayey soils, the engineering properties of those soils may need to be improved to make them suitable for construction. the aim of this paper is to study the effect of using lime, natural pozzolana or a combination of both on the geotechnical characteristics of two cohesive soils. lime or natural pozzolana were added to these soils at ranges o...

Halophilic bacteria are commonly found in natural environments containing significant concentration of NaCl such as inland salt lakes and evaporated sea-shore pools, as well as environments such as curing brines, salted food products and saline soils. Dependence on salt is an important phenotypic characteristic of halophilic bacteria, which can be used in the polyphasic characterization of newl...

Chloride binding capacity and its effect on the microstructure of mortar made with marine sand (MS), washed MS (WMS) river (RS) were investigated in this study. The chloride contents, hydration products, micromorphology pore structures mortars analyzed. results showed that there was a diffusion trend for ions from surface fine aggregate to cement hydrated products. During whole curing period, f...

The aim of this study was to analyze effect cherry tomato paste for nitrite replacement on loin ham. Loin hams were prepared with at three levels curing solutions (control: NPS 1.2%, salt 1.2% and 1%, 3%, 5%). pH tended decrease as the amount increased. lightness decreased a significant difference increased (p<0.05). Yellowness chroma increase in paste, while redness hue angle treatment 3% t...

Previous studies (Costilow et al., 1955) demonstrated that the yeasts found to be most prevalent in cucumber fermentations were completely inhibited by 0.01 per cent sorbic acid in an 8 per cent salt (NaCl) medium at pH 4.6. As the pH was increased and/or the salt concentration decreased, more sorbic acid was required for complete inhibition of some of the yeasts tested. Cultures of Pediococcus...

During the past decade, substantial progress has been made in delineating clinical features of the epilepsies and the basic mechanisms responsible for these disorders. Eleven human epilepsy genes have been identified and many more are now known from animal models. Candidate targets for cures are now based upon newly identified cellular and molecular mechanisms that underlie epileptogenesis. How...

Objective(s): A Box-Behnken design was used for evaluation of Eudragit coated diclofenac pellets. The purpose of this work was to optimize diclofenac pellets to improve the physicochemical properties using experimental design. Materials and Methods: Diclofenac was loaded onto the non-pareil beads using conventional coating pan. Film coating of pellets was done at the same pan. The effect of pla...

UNLABELLED Adequate polymerization plays an important role on the longevity of the composite resin restorations. OBJECTIVES The aim of this study was to evaluate the effect of light-curing units, curing mode techniques and storage media on sorption, solubility and biaxial flexural strength (BFS) of a composite resin. MATERIAL AND METHODS Two hundred and forty specimens were made of one comp...
