Characterisation of complex mixtures is a common tool especially in oil processing industry. Characterisation procedures result in experimentally gained characterisation curves, but for the simulation of industrial processes the definition of a substitute mixture is required. Traditionally, a system of pseudocomponents is derived from the TBP (True Boiling Point) characterisation curve, but the...

The binding of a popular food supplement and well-known antioxidant, dihydro-alpha-lipoic acid (DHLA) to human serum albumin (HSA) was characterised. monitored by several spectroscopic methods together with the molecular docking approach. HSA able bind DHLA moderate affinity, 1.00?0.05?104 M-1. Spectroscopic data demonstrated that preferential site for on is IIA (Sudlow I). Both experimental an...

Maize and sorghum are staple foods in many African countries. Along with rice, they constitute the bulk of cereals consumed by populations northern Côte d'Ivoire. These used either directly or indirectly malted and/or fermented form preparation several traditional production alcoholic beverages such as dolo a local beverage. This study aims at physicochemical characterization determination effe...

Surface characterisation system needs to be updated constantly with the emergence of new algorithms and methods in the field of surface metrology. As function modules in current surface characterisation system are tightly coupled together, it is not conducive to the reuse of function modules and innovation of overall system. A lot of redundant and duplicate works have been done in present chara...

the main objective of this study was to investigate the effi ciency of biological treatmentof azo dye-containing wastewater with a sequencing batch reactor system, followed by ultrafi ltration.the performance of the system was quantifi ed by measuring the chemical oxygen demand and azo dyeconcentration. the biodegradation was carried out under combined alternating anaerobic and aerobiccondition...

A bipartite graph G is known to be Pfaffian if and only if it does not contain an even subdivision H of K3,3 such that G − V H contains a 1-factor. However a general characterisation of Pfaffian graphs in terms of forbidden subgraphs is currently not known. In this paper we describe a possible approach to the derivation of such a characterisation. We also extend the characterisation for biparti...

In this paper we give a global characterisation of classes of ultradifferentiable functions and corresponding ultradistributions on a compact manifold X. The characterisation is given in terms of the eigenfunction expansion of an elliptic operator on X. This extends the result for analytic functions on compact manifold by Seeley [See69], and the characterisation of Gevrey functions and Gevrey u...

Nucleobase containing compounds might constitute a potential alternative to conventional antibiotics in the treatment of Helicobacter pylori infections. N4-alkyloxycarbonyl-cytosine derivatives were synthesized and subjected to basic physicochemical characterisation including assessment of hydrolytic stability in various matrices. pH-rate profiles of selected compounds (range 0-12) were constru...

Pectinate gel beads containing Thai mango seed kernel extract (MSKE, cultivar 'Fahlun') were developed and characterised for the purpose of colon-targeted delivery. The MSKE-loaded pectinate beads were prepared using ionotropic gelation with varying pectin-to-MSKE ratios, MSKE concentrations, and concentrations of two cross-linkers (calcium chloride and zinc acetate). The formulated beads were ...
