System development of estimated figures of volume production plan
The relevance of this problem is primarily determined by a necessity of improving production efficiency in conditions of innovative development of the economy and implementation of Import Substitution Program. The purpose of the article is development of set of criteria and procedures for the comparative assessment of alternative volume production plans and choice of optimum alternative. The leading method of the study of the problem is economic-mathematical modeling, providing the variability of volume plan development on the basis of different factors and variables, which reflect actual operating standards of a particular study subject. The results of the study: In the article, economic-mathematical model for development of aggregate production plan was presented, on the basis of which alternatives was produced, estimated figures, characterizing efficiency of derived alternatives, were justified, the key factors, which determine a specific set of variables and constraints, were considered. The article materials can be useful for experts, which are specialized in planning of production and distribution of the production program in choosing optimum alternative of aggregate production plan. © 2016 Brazhnikov et al

How Neanderthals gripped retouchers: experimental reconstruction of the manipulation of bone retouchers by Neanderthal stone knappers
When studying bone retouchers, researchers pay close attention to the morphological characteristics of the tool’s active zone, and the lithic raw material processed. In our research, we found that the orientation of the bone retoucher in the hand and the grip employed to retain and manipulate it are crucial factors that affect the morphological characteristics of the retoucher’s active zone. By examining two alternative grips for manipulating bone retouchers ((1) Using all the fingers of one hand in a power grip; (2) Using only the first three digits of one hand in a pinch grip), we found that when the retoucher is held in the first manner, the active area is larger, as is the amount of bone removed by the retoucher. When the retoucher was pinched with only three fingers in a precision grip, retouch damage was more densely concentrated and less bone was removed. The orientation of the retoucher in the hand and the grip employed have a greater influence on the active area than the extent of retoucher use, which we assessed by measuring the number of stone tool edges processed. By gripping the retoucher with all the fingers of one hand, the knapper automatically applies greater force, which results in the removal of more bone. Comparison of experimental bone retouchers with those recovered from Middle Paleolithic archaeological contexts in Chagyrskaya Cave (Altai, Russia) revealed that Altai Neanderthals practiced two methods of grasping bone retouchers, with a three-finger pinch grip being dominant. © 2021, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature

Investigation of oncolytic potential of vaccine strains of yellow fever and tick-borne encephalitis viruses against glioblastoma and pancreatic carcinoma cell lines
Introduction. Flaviviruses, possessing natural neurotropicity could be used in glioblastoma therapy using attenuated strains or as a delivery system for antitumor agents in an inactivated form.
Objective. To investigate the sensitivity of glioblastoma and pancreatic carcinoma cell lines to vaccine strains of yellow fever and tick-borne encephalitis viruses.
Materials and methods. Cell lines: glioblastoma GL-6, T98G, LN-229, pancreatic carcinoma MIA RaCa-2 and human pancreatic ductal carcinoma PANC-1. Viral strains: 17D yellow fever virus (YF), Sofjin tick-borne encephalitis virus (TBEV). Virus concentration were determined by plaque assay and quantitative PCR. Determination of cell sensitivity to viruses by MTT assay.
Results. 17D YF was effective only against pancreatic carcinoma tumor cells MIA Paca-2 and had a limited effect against PANC-1. In glioblastoma cell lines (LN229, GL6, T98G), virus had no oncolytic effect and the viral RNA concentration fell in the culture medium. Sofjin TBEV showed CPE50 against MIA Paca-2 and a very limited cytotoxic effect against PANC-1. However, it had no oncolytic effect against glioblastoma cell lines (LN229, T98G and GL6), although virus reproduction continued in these cultures. For the GL6 glioblastoma cell line, the viral RNA concentration at the level with the infection dose was determined within 13 days, despite medium replacement, while in the case of the LN229 cell line, the virus concentration increased from 1 × 109 to 1 × 1010 copies/ml.
Conclusion. Tumor behavior in organism is more complex and is determined by different microenvironmental factors and immune status. In the future, it is advisable to continue studying the antitumor oncolytic and immunomodulatory effects of viral strains 17D YF and Sofjin TBEV using in vivo models
