Coal maceral composition has a great effect on gas adsorption and diffusion. The interaction between supercritical CO2 (SCCO2) fluid will affect diffusion behavior in coals. Thus, the diffusivity derived from kinetics of CH4 vitrinite- inertinite-rich coals with low-violate bituminous rank collected Hancheng mine Weibei coalfield pre- post-SCCO2 exposure (SFE) were tested at conditions 45 °C 0....

Natural antioxidants have renewed value for human health and the food industry. Green labeling is becoming an important attribute consumers impacting processing formulations. Clean label another that ranked third after “free-from” claims “a good source” of nutrient claims. attributes also are higher than local, seasonal, organic. Techniques able to preserve valuable characteristics natural anti...

The evolution of the microstructure changes during hot deformation high-chromium content stainless steels (martensitic steels) is reviewed. microstructural taking place under high-temperature conditions and associated mechanical behaviors are presented. During continuous dynamic recrystallization (cDRX), new grains nucleate growth in materials with high stacking fault energies (SFE). On other h...

Sutherlandia frutescens (SF), a popular traditional medicinal plant found in various parts of southern Africa, is used for treatment or management of HIV/AIDS and other diseases including cancer. However, its toxicity profile has not been fully established. The aims of this study were to examine the effects of 70% ethanol (SFE) and deionised water (SFW) extracts on normal isolated human T cells...

tea and sesame seed oils extracted by different methods (including supercritical fluid extraction (sfe), at a pressure of 350 atm, a temperature of 60oc, a static extraction time of 20 minutes, a dynamic extraction time of 30 minutes and 150 g kg-1 of ethanol as a modifier). solvent (se) and ultrasound-assisted solvent extraction (ue)), as natural anti-oxidants, were evaluated during 15 days st...

In secure computation among a set P of players one considers an adversary who can corrupt certain players. The three usually considered types of corruption are active, passive, and fail corruption. The adversary’s corruption power is characterized by a so-called adversary structure which enumerates the adversary’s corruption options, each option being a triple (A, E, F ) of subsets of P , where...

OBJECTIVE This study aimed to incorporate silver nanoparticle solutions (AgNP) in an orthodontic adhesive and evaluate its physicochemical and antimicrobial properties. MATERIAL AND METHODS Silver nanoparticle solutions were added to a commercial adhesive in different concentrations (w/w): 0%, 0.11%, 0.18%, and 0.33%. Shear bond strength (SBS) test was performed after bonding metal brackets t...

A reverse phase ultra performance liquid chromatography and photodiode array (UPLC-PDA) detection method was established for the determination of six alkaloids in Zoagumhwan (ZGW), and further for investigating the influence of nonpolar substances on the extraction efficiency of these alkaloids. The method was based on a BEH C(18) (50 mm × 2.1 mm, 1.7 μm) column and mobile phase of aqueous phos...

BACKGROUND Hydrodistillation (HD) and steam-distillation, or solvent extraction methods of essential oils have some disadvantages like thermal decomposition of extracts, its contamination with solvent or solvent residues and the pollution of residual vegetal material with solvent which can be also an environmental problem. Thus, new green techniques, such as supercritical fluid extraction and m...
