В представленной работе с помощью пакета программ STATISTICA 6.0 проведен регрессионный и корреляционный анализ экспериментальных данных. И на основании полученных результатов определено оптимальное значение компонентов входящих в рецептуру многокомпонентных рыбных рубленых изделий на основе белипа. Ключевые слова: рыбная рубленая масса, выжимки ягод (пищевые отходы соковых производств), рыбная компонента, творожено-жировая компонента, структурно-механические показатели. = In this article the regressive and correlative analysis of the experimental data is introduced. The programme STATISTICA 6.0 was used. On the base of the data the optimum value of the components in the recipe of minced meat-vegetable paste was determinated
Additional data about fauna and distribution of the subgenus Furcilethrus Nikolajev, 1968, the genus Lethrus Scopoli, 1777 (Coleoptera: Geotrupidae: Lethrinae)
Review of the subgenus Furcilethrus Nikolajev, 1968 of the genus Lethrus Scopoli, 1777 is given. Two new species are described from mountains of Tajikistan: L. muskinabadensis Nikolajev et Ivanova, sp. n. from southern slopes of Karategin Range and L. rustam Nikolajev et Ivanova, sp. n. from western part of Vakhsh Range. The fisrt new species is close to L. michailovi Nikolajev et Schukronajev, 1977 known from northern slopes of Surkhku Range; the second new species is close to L. sohrab Nikolajev, 1976 also known from Surkhku Range. Lectotype of L. furcatus Jakovlev, 1890 (deposited in Zoological Institute of Russian Academy of Sciences, Saint Petersburg) is designated. New synonymy is established: L. tenuidens Reitter, 1890 = L. staudingeri Reitter, 1893, syn. n. Lethrus obsoletus Semenov, 1894 is considered as subspecies of L. tenuidens Reitter, 1890: Lethrus tenuidens obsoletus Semenov, stat. n. Distribution of all known species of the subgenus Furcilethrusis detailed. Key to species of the genus on males is given
СРАВНИТЕЛЬНЫЙ АНАЛИЗ ДИНАМИКИ ЧИСЛЕННОСТИ КОПЫТНЫХ ЖИВОТНЫХ В НАЦИОНАЛЬНОМ ПАРКЕ «СМОЛЕНСКОЕ ПООЗЕРЬЕ»
The analysis of long-term data on the number of ungulates of the national park "Smolenskoe Poozerye", roe deer ( Capreolus capreolus L. 1758), elk ( Alces alces L. 1758) and wild boar ( Sus scrofa L. 1758), revealed the following features of the dynamics of their populations. The number of roe deer was lower than that of other large representatives of herbivores, is subject to sharp fluctuations and is currently in the process of decline. The boar population has the highest number, and the elk population has the lowest fluctuations in this indicator. The numbers of elk and wild boar are on the rise. Judging by the size of the population, 2010 was the most successful year for all three species: the size of the population reached the maximum values for the entire observation period.Анализ многолетних данных по численности копытных животных национального парка «Смоленское Поозерье», косули ( Capreolus capreolus L. 1758), лося ( Alces alces L. 1758) и кабана ( Sus scrofa L. 1758), выявил следующие особенности динамики их популяций. Численность косули оказалась ниже, чем у остальных крупных представителей травоядных, подвержена резким колебаниям и в данный период находится в процессе снижения. Самой высокой численностью обладает популяция кабана, а наименьшие колебания этого показателя характерны популяции лося. Численность лося и кабана находятся на стадии подъема. Судя по размеру популяции, 2010 год оказался наиболее благополучным для всех трех видов: размер поголовья достиг максимальных показателей за весь период наблюдений
Mathematical modeling of physico-chemical processes in the polymerization of multicore cable products
In this article the question of simulation of no stationary process in the polymerization of multilayer cable product is considered. The model allows predicting time of full polymerization rubber shell
Improving the energy efficiency of CNC grinding machines
Background. The high efficiency of the use of automated control systems for
abrasive processing in mass and large-scale production makes it possible to increase
productivity up to 70%, as well as to increase the metal removal rate by 30-50% while stabilizing
the quality and geometric parameters of processing. Electric drives used in CNC
machines consume a significant amount of energy, so energy costs must be taken into account
when choosing them. Estimation of energy consumption requires studying the parameters
of the operation of the feed electric drive and the main movement and obtaining
information about the current values of technological modes at a certain load. Materials
and methods. When determining the coefficients of performance (COP), carried out when
assessing the energy efficiency of CNC machines, methods of direct and indirect power
measurement were used. Results. It has been established that the higher the efficiency value,
the lower the losses and power consumption of the electric motor and the higher its energy
efficiency, the less the motor consumes energy, heats up less, it has a longer service
life, which leads to an increase in the MTBF. Conclusions. It is recommended to use IE3
energy efficiency class motors in CNC grinders, because they can operate without feedback
with an open-loop control system and with positioning devices. This will save on feedback,
which is also an undoubted advantage
Localization of plastic deformation in HCP-, BCC- and FCC-alloys at indentation
Conference: International Scientific Conference on Materials Science - Composites, Alloys and Materials Chemistry (MS-CAMC) Location: Peter Great St Petersburg Polytechn Univ, Saint Petersburg, RUSSIA Date: NOV 20-21, 2019Using instrumental indentation, we studied the regularity of elastoplastic deformation of workpieces from alloys aluminum AMc, titanium VT23 and steels 45, HVG with FCC, HCP and BCC lattices, respectively. It was shown that with increasing indentation depth, instrumental hardness (H1T), elastic modulus (E1T), their ratios (HIT/EIT) tend to the values of classical microhardness Hm, Young’s modulus E and their ratio (Hm/E). The nature of localization of plastic deformation of alloys near the surface of the indenter is determined. The reason for the hard workability of titanium-based alloys is determinedVytauto Didžiojo universitetasŽemės ūkio akademij
Evaluation of the properties of complexing agent-collectors of eudialyte flotation
Acid-based and complexing properties of reagent-collectors (carboxylic and hydroxamic acids, styrylphosphonic acid and dialkyl ether of phosphoric acid) for flotation of zirconium-containing minerals have been studied. Stability constants for zirconium compounds of investigated reagents have been determined. Eudialyte-containing ore flotation has proved high efficiency of hydroxamic acid
