Until now, the relationship between the fat and oil composition and their oxidation stability has been studied only at elevated temperatures (typically above 100 °C). Therefore, the initial oxidation rates of 19 edible fats and oils were determined as an increase in the peroxide value during storage in the dark at 35 °C with free access to air (oxygen). The initial oxidation rates of fats and oils were compared with parameters characterising these fats and oils (peroxide value, acid value, fatty acid composition, antioxidant capacity, and tocochromanol content). Using a simple correlation anal

The paper is devoted to the problem of determining the composition of reservoir gas for gas condensate fields. A methodology for planning gas condensate tests (GCT) is proposed, which allows to assess the possibility of obtaining conditioned samples of reservoir fluid. For the case when it is impossible to take conditioned samples, an approach for their interpretation is developed.At the first step it is proposed to numerically create a set of compositions by adding to the gas of the laboratory “depleted” composition a certain amount of condensate equilibrated to it.

Stoichiometric proportions and excess amounts of initial powders were used to indicate the effects of final composition of synthesized tungsten silicide powders. Since the initial powder compositions affect the reaction times, all compositions were mechanically alloyed for 1 hour. In addition, thermodynamic calculations of all compositions were theoretically conducted. The dominant phases are WSi2 and MgO for all mechanically alloyed powders.

The initial/final mass relation (Mi–Mf) for small and intermediate mass stars depends strongly on the initial chemical composition (Z). Two factors play an important role in this effect: the dependence on Z of mass loss rates and the carbon-oxygen core initial mass. For heavy element abundances Z = 0.001 and Z = 0.02 the greatest differences of Mf and Mi are found between 1.5 < Mi/M⊙ < 4 and may be as great as 0.1 M⊙.

The influence of pore size and initial compositions of stratifying organic mixtures in microsized pores on the composition and stability of coexisting phases in a heterogeneous state has been demonstrated by means of equilibrium chemical thermodynamics. Using the example of several binary organic systems, it has been shown that, unlike macrosized phases, mutual solubilities of components in microsized pores substantially depend on the size of a pore and initial composition of a mixture, and even characters of solubility dependences on pore size are different for mixtures of different compositi

Although these elastomers are processable thermoplastics, they all exhibit a Payne effect much like traditional crosslinked materials.

Annotation:

A method was developed for calculating the optimum fractional composition of the initial disperse filler of a polymer composite material based on three-dimensionally crosslinked (cured) elastomer. As the optimisation criteria, an examination was made of the coefficient of dynamic viscosity of the polymer suspension and the initial viscoelasticity modulus of cured low-molecular-weight rubbers with terminal functional groups, filled with polyfractional silicon dioxide. The influence of the packing density of the filler particles on the energy of mechanical failure was investigated. A composite m

Investigation influence of methods obtaining polymer compositions based on thermostable polymers (aromatic polyamide, fluoropolymer and phenoplast) and dispersed silica on quality of their compound. It had been investigated quality of compound of initial components of polymer compositions based on thermostable polymers according to methods of obtaining it. This parameter had been estimate by uniform distributions of fillers in polymer compositions with help thermal method and microscopy.

The effect of the quantitative and qualitative composition of mixed binders on the physical and mechanical properties of cement compositions has been experimentally established. A cement stone with a different amount and dispersion of mineral fillers was considered. The research results showed that the plastic strength of the hardening system depends on its initial composition. The defects embedded in the material during its technological processing into the product determine the local stress-strain state of the structure, the nature of cracking and the fracture surface. The effect of technolo

Producing powder compositions using conventional processing technology can lead to the formation of large agglomerates and, therefore, makes it difficult to obtain a uniform microstructure. The production of composites by self-propagating high-temperature synthesis can reduce costs and the number of technological stages, as well as lead to obtaining composites that are more homogeneous. Synthesis by the combustion of mixtures of powder reagents of sodium azide (NaN3), fluoroplastic (C2F4), aluminum and titanium with different ratios of reagents in a nitrogen gas atmosphere at a pressure of 4MP
