Diet rich in polyphenols may be important factor in preventing cardiovascular, neoplastic diseases and slowing down the aging processes. Because tea (Camelia sinensis) is most popular beverage containing relatively large amounts of polyphenols, it could be tremendously important source of polyphenolic constituents in human diet. However, there has been no data on the tea extracts use in particu...

The formation of exciplexes ( non-emitting or poorly emitting ) is proposed as a cause of the deviations of the experimental data from the classical model of excited state electron transfer in polar solvents yielding radical ion pairs. Experimental evidences for the formation of such exciplexes are discussed. Simulation of the dependencies of the quenching rate constant vs. Gibbs energy of elec...

This paper deals with the problem of checking the consistency of the speech corpus during recording in terms of the level of speech power of individual recordings. The question was whether or not setting of the limits of RMS value is useful for checking the volume consistency of recordings destinated for unit selection speech synthesis.

This paper studies sufficient conditions for deriving the kappa distribution in polytropic plasmas by an improved method compared with previous work [R. Guo, Phys. Plasmas \textbf{27}, 122104 (2020)]. We find that equation of state can lead to without any other assumptions one dimension. In higher dimensions, extra assumption global must only depend on energy is still needed. addition, self-con...

This research is an analysis and a synthesis of papers case studies concerning the project-based learning management. The brainstorming among experts as well their opinions on management process are utilized to define appropriate for students in vocational technical education Thailand. results this reveal that consists 5 steps, i.e. preparation, topic definition, creation test, presentation, ev...

Our research focuses on the relationship between ESG performance of South Korean multinational companies and stock price crash in next year. For our study, we divide samples into three different categories - namely, all companies, (MNC) non-multinational companies(non-MNC). major findings are as following. First, find negative social (S) score future crash, indicating that their prevents risk. ...

There are several models f or heat conduction - non-Fourier equations in the literature that important for various practical problems. These manifest themselves partial differential equations, and application of which requires developing efficient reliable solution methods. In present paper, we focus on analytical solutions two models, specifically Maxwell-Cattaneo-Vernotte Guyer-Krumhansl as t...

The analysis of radiative transfer in photoreactors is often crucial for operating efficient photoreactions. This article aims to present a complete experimental and theoretical coupled approach allowing containing particulate media. TiO2 powder, widely used photocatalysis, was selected as case study material this work. First, Mie theory adapted assess the effective properties heterogenous powd...

Let the Ornstein–Uhlenbeck process $$(X_t)_{t\ge 0}$$ driven by a fractional Brownian motion $$B^{H }$$ described $$dX_t = -\theta X_t dt + \sigma dB_t^{H be observed at discrete time instants $$t_k=kh$$ , $$k=0, 1, 2, \ldots 2n+2 $$ . We propose an ergodic type statistical estimator $${\hat{\theta }}_n $${\hat{H}}_n and $${\hat{\sigma to estimate all parameters $$\theta H $$\sigma in above mod...
