“…We will conduct additional studies of the indicator of self-sufficiency in order to identify the relationship between the data presented in Table 2. For this, we will be using the statistical control methods, namely, the scatter chart proposed by A. Cohen, T. Tiplica, A. Kobi, J. Henn, K. Meindl (Cohen et al, 2016;Henn et al, Meindl, 2015). Correlation study indicators "production" and "import" are presented in Figure 1.…”

The article is dedicated to the new political course of the Russian Federation, aimed at overcoming the economic blockade of the countries of Europe, as well as the United States. Effective management of food enterprises should take into account the new economic con-ditions for the functioning of the food economic subsector. In view of the crisis associated with the spread of coronavirus, falling oil prices, the ruble situation, the development of an economic course to adapt the Russian food industry becomes paramount. Therefore, the purpose of this article is a set of government measures to regulate the dairy food complex of the Russian Federation, both federally and regionally for the period 2008-2018. An analysis of the dynamics of milk industry indicators showed that the level of self-sufficiency for the period 2008-2018 was below the standard: 0.90. The study correlated the economics "im-port" and "self-sufficiency". Based on the data, it is concluded that the Russian Federation needs global innovation in the food industry mainly to the effective management of the agricultural dairy subsector.

“…On the other side, details coefficients have a mean equal to zero. This characteristic could be useful to detect change in variance, because the mean change does not affect the details coefficients, as we have shown in our previous work (Cohen, Tiplica, & Kobi, 2016), in which we proposed DeWave control chart in order to monitor variance change.…”

“…The design of experiments is a useful tool for assessing the variations of results from experiments and is applicable for simulating the results in different fields . In the present study, we applied a general full factorial method with different numbers of levels in the order of main effect for inhibition efficiency to design the experiments.…”

The introduction of two new benzimidazole derivatives, 2-nonyl-1H-benzo [d] imidazole (NB) and 2-benzyl-1-hexyl-1H-benzo [d]imidazole (HB), as corrosion inhibitors for steel is presented, and their activities are compared with 1Hbenzo[d]imidazole (B). The experimental performance of these molecules was evaluated by electrochemical techniques, surface observations, and contact angle measurement. The results showed the prominent action with inhibition efficiencies of 98.8% and 99.3% for 3 mM of NB and HB, respectively, at 303K. They are adsorbed on the metal surface base on Langmuir isotherm. It is noteworthy to note that increment of environment acidity causes more efficiency for both molecules so that the order of inhibitive activity in different pHs is pH = 2>pH = 1>pH = 0.1. Additionally, HB provides little better protection than NB. Statistical analysis was conducted to identify influential factors on the efficiency of HB and NB. A general factorial model in the main effect order was used by design of experiment 7 software. Analysis of variance resulted in acceptable R 2 values of 99% and 98% and significance of the applied model. Quantum chemical calculations were carried out to find the optimum structure, molecular parameters, and local reactive sites in gas and solution phase. Calculations exhibited a planar structure for 1-hexyl-1H-benzo[d]imidazole and 2-nonyl-1H-benzo [d]imidazole that is the reason of their high efficiencies.
