The objective of this study was to determine the effects of a CO, treatment on the pH and soluble concentrations of inorganic contaminants in alkaline fly ash and spent shale solid wastes. A two-level (low and high), three-variable (moisture, time and pressure) statistical experiment was used to determine optimum CO, treatment conditions. Treated and untreated samples were subjected to solubili...

This paper aims to investigate the impact of soluble magnesium on structure C-S-H formed at elevated temperature. Magnesium chloride hexahydrate, calcium oxide and silica fume were used in preparation Mg2+ modified C-S-H. The obtained solid liquid samples synthetic characterized with XRD, FTIR, TGA, etc. structural features Results show that mineralogical compositions synthesized are highly rel...

BACKGROUND Commercially available curcumin preparations contain a mixture of related polyphenols, collectively referred to as curcuminoids. These encompass the primary component curcumin along with its co-purified derivatives demethoxycurcumin and bisdemethoxycurcumin. Curcuminoids have numerous biological activities, including inhibition of cancer related cell proliferation and reduction of am...

Solid dispersions is an efficient means of improving the dissolution rate and hence the bioavailability of a range of poorly soluble drugs. This article reviews the various types of solid dispersion, preparation techniques for solid dispersion and compiles some of the recent technologies. Some of the practical aspects to be considered for the preparation of solid dispersions, such as selection ...

A new approach for isolating and recovering biological macromolecules using membrane-encapsulated soluble ligand conjugates was investigated. Membrane-encapsulated solid adsorbents have been successfully developed and employed in our laboratory to isolate and purify proteins and enzymes directly from culture broths. This new concept also makes it possible to use soluble ligand conjugates instea...

Different concentrations of oily waste were added in a discontinuous mode and recurrently to anaerobic continuous stirred tank reactors fed with cow manure and food waste. Four continuous stirred tank reactors were run in parallel. A control reactor (R1) received no additional oil and R2, R3 and R4 received increasing concentrations of oil in two different experimental approaches. First, the li...

The use of plants to monitor heavy metal pollution in the terrestrial environment must be based on a cognizance of the complicated, integrated effects of pollutant source and soil-plant variables. To be detectable in plants, pollutant sources must significantly increase the plant available metal concentration in soil. The major factor governing metal availability to plants in soils is the solub...

An assessment of elastase-substrate kinetics and adsorption at the solid-liquid interface of peptide-bound resin was made in an approach to the solid-phase detection of human neutrophil elastase (HNE), which is found in high concentration in chronic wound fluid. N-succinyl-alanine-alanine-proline-valine-p-nitroanilide (suc-Ala-Ala-Pro-Val-pNA), a chromogenic HNE substrate, was attached to glyci...

A main concern about cement materials for the construction of the repository is altering the groundwater to high alkalinity around the repository. Under such chemical condition, the behavior of the silicic acid is one of the key factors to estimate the initial condition of the repository system after the backfill. Since the solubility of silicic acid is extremely large in pH larger than 10, the...
