a model capable of predicting the minimum content of aflatoxin m1 (afm1) in iranian while brine cheese has been developed using a chemometric approach to determine the optimum processing conditions. renneting temperature, cut size, stirring time, press time, curd size and saturated brine ph were all regarded as process variables. three-dimensional response surface and contour plots were drawn. ...

Twenty six 3.8 kg blocks were made on each of 3 different days. A block was analyzed prior to brine salting. Blocks (5) were placed into each of 5 different saturated brines at 12, 15, 18, 21, and 24◦C. One block was removed from each brine tank after 1, 4, 8, 16, and 24 d, weighed, sampled, and analyzed for salt and moisture. Weight loss (net of moisture loss and salt uptake), salt uptake, and...

Herein, a method of physical modeling CO2-brine-rock interaction and in-situ characterization mineral pore evolution is established. The nested preparation installation the same sample with different sizes could protect keep integrality millimeter-size in conventional high-temperature high-pressure reactors. This paper establishes procedure to obtain three-dimensional comparison minerals pores ...

the chemical surfactant flooding can mobilize the trapped oil by lowering the interfacial tension between oil and brine and in some cases altering the reservoir rock wettability. in this work, the effect of surfactants on oil/brine interfacial tension was experimentally investigated. first, the effect of surfactants concentration was surveyed. afterwards, the effect of salinity on surfactant be...

[1] It is well known that brine drainage from growing sea ice has a controlling influence on its mechanical, electromagnetic, biological and transport properties, and hence upon the buoyancy forcing and ecology in the polar oceans. When the ice has exceeded a critical thickness the drainage process is dominated by brine channels: liquid conduits extending through the ice. We describe a theoreti...

Knowledge of the physico-chemical properties of sea-ice with its inclusions of liquid brine is essential for our understanding of the role of polar ice covers in climate change. Spin-Echo, Diffusion-weighted MRI and Na-NMR were conducted on sea-ice sampled in Arctic Alaska to study the thermal evolution of brine inclusions over a temperature range from –30 to –3°C. An in-plane resolution of 100...

Introduction: Mineralogical studies have demonstrated that the nakhlite SNC meteorites have preserved the effects of water-rock interaction between a hydrothermal brine and the nakhlite parent rocks on Mars. Brittle fracturing and corrosion of olivine grains and mesostasis associated with the hydrothermal event have left veins of zoned Fe-carbonate, Fe-smectite (with minor serpentine), and an a...

Water alternating gas (WAG) technique is used in the petroleum industry to inject carbon dioxide (CO2) into underground formations either for sequestration or enhanced oil recovery (EOR) processes. CO2 injection causes reactions with formation brine or aquifer and produces carbonic acid, the acid dissolves calcite and changes flow behavior significantly. Modeling and investigating effects of CO...
