Abstract Reduced relativistic gas (RRG) is a useful approach to describe the warm dark matter (WDM) or the warmness of baryonic matter in the approximation when the interaction between the particles is irrelevant. The use of Maxwell distribution lead

The bonfire (Cannabis sativa) was delignified with the reaction mixture “acetic acid - hydrogen peroxide - sulfuric acid catalyst - water” at a sulfuric acid concentration of 0.45%, a liquid module of 6, and a temperature of 85 °C. The effect of

Acid prehydrolysis does not impede subsequent peroxide delignification, increases the mass fraction of α-cellulose, and improves the reactivity of cellulose but does not ensure a high degree of modification. Aqueous prehydrolysis is less effective.

An environmentally clean peroxide method of manufacturing cellulose was developed as an alternative to the traditional pulping method. Spruce and birch are delignified with hydrogen peroxide in acid medium in the presence of catalysts and the cellulo

The one-loop divergences in higher-derivative quantum gravity with scalar field are calculated with the use of a non-minimal two-parameter gauge fixing condition. The explicit gauge fixing parameter dependence of the effective potential is demonstrat

In the framework of the recently proposed asymptotically finite gauge models the cosmological constant is essentially weakened by quantum effects. The next (and more general) claim is that the coupling between quantum fields may suppress their contri

We search for new kinds of classical potentials in two-dimensional induced gravity, which have trivial one-loop quantum corrections. First of all the gauge dependence of the effective potential is studied. The unique effective potential, introduced b

We consider the interaction of matter fields with classical gravitational background in the framework of Nambu-Jona-Lasinio (NJL) model. Gravity includes not only metric but also independent torsion field. The renormalization group analysis shows tha
