Kinetics of the alkaline hydrolysis reaction of methyl esters of substituted 4,5-dimethoxy-N-phenylanthranilic acids has been studied in the binary solvent of dioxane-water at 55, 75, 85°C. It has been found that at each experimental temperatures lgkT dep... see more

At production, collection and transport of low – pressure gas to deep water offshore platforms in sea conditions because of thermodynamic indices change in the system, complications are generated in connection with liquid phases – separation. These compli... see more

With use of thermodynamic approaches the variant of mathematical model of mechanics of the description of parameters of fatigue strength while in service is offered. The connection of the obtained relationships with the modern criteria of durability of bo... see more

An innovative computationally efficient method for the simultaneous determination of top dead centre (TDC) offset and pressure offset is presented. It is based on characteristic deviations of the rate of heat release (ROHR) that are specific for both offs... see more

In the current study, thermal degradation and thermodynamic properties of ascorbic acid, total phenolic content, and antioxidant activity of convective dried kiwi fruits were investigated. To determine kinetic model describing thermal degradation of these... see more

When studying the temperature dependences of the acoustic absorption and the modulus of elasticity, absorption peaks are often observed, which correspond to the characteristic step on the temperature dependence of the modulus of elasticity. Such features ... see more

A mixture of vegetable oil and animal fat as raw materials was optimized by simplex-centroid mixture design to produce a type of biodiesel with good oxidative stability, flow properties and reaction yield. Further, kinetic and thermodynamic parameters of ... see more

An important step in creation of potential drugs is to confirm the structure of the compounds synthesized. This requires the use of modern physical and physico-chemical methods of research. Nowadays a promising scientific direction for searching biologica... see more

The utilisation of near-neutral salts as activators to produce alkali-activated slag cements offers several technical advantages, including reduced alkalinity of the binders, minimising the risk associated with handling of highly alkaline materials, and b... see more
