СТРАТЕГИЧЕСКАЯ УСТОЙЧИВОСТЬ ПРОМЫШЛЕННЫХ КОМПАНИЙ: ПОДХОДЫ К ПОНИМАНИЮ И АНАЛИЗ РИСКОВ
The article analyzes approaches to the strategic sustainable development of industrial organizations. Based on the review of Russian and foreign literature, three approaches to the strategic sustainable development of industrial organizations were identified: process, system and time approaches.Based on the analysis of annual reports of Russian industrial organizations, it was possible to identify and systematize the risks that affect the strategic stability of Russian industrial organizations. Among the identified risks, the following risk groups are identified: country risks, legal risks, industry risks, foreign economic risks, market risks, production and technological risks, financial risks, reputational risks, environmental risks, information risks, social risks and strategic risks.As a result of correlation and regression analysis, the most significant risks affecting the achievement of strategic goals of Russian industrial organizations were identified. These include: country risks, industry risks, and strategic risks. The obtained regression model allows us to predict the degree of achievement of strategic goals of Russian industrial organizations under the influence of various risks.В статье анализируются подходы к стратегическому устойчивому развитию промышленных организаций.

Morpho-functional basis of endothelial dysfunction in diabetes mellitus
The diabetes mellitus (DM) inevitably progresses and leads to complications, among which the main place is occupied by micro- and macroangiopathies. The presence of endothelial damage in DM can be established even before macroscopically significant damage to the vessel. At the same time, there is no summary ED characteristic for diabetes. The aim of the study is to make a comprehensive evaluation of ED in DM -1 and DM-2 types.Materials and methods of research. 60 persons, including 53 DM type 1 and type 2, with a severe course (state of decompensation) participated in the present study. We used the method of estimating ED by the number of circulating desquamation endothelial cells (CECs) at the stages of decomposition with simultaneous determination of NO2- and NO3- metabolites of nitric oxide.Results and discussion. In patients with diabetes, the level of CECs increased in 3-5 times and ranged from 1800 to 11,200 cells / ml. The average amount of CECs in patients with diabetes was 3358.5 ± 366.3 cells / ml.Conclusions: Endothelium is involved in the pathological process at DM. This is evidenced by a significant increase in CECs in the blood plasma. The use of this method allows to detect ED before clinically considerable vascular impairment and reflects the severity of the course and duration of DM
The influence of the flour amylolytic enzymes activity, dosage of ingredients and bread making method on the sugar content and the bread quality
The aim of this study was to study the effect of the sugar dosage, improver dosage,
type of bread making methods and the amylolytic activity of five different types of wheat flours
on the sugar content and the bread quality. The sugar content in the bread crumb was determined
using the Bertrand’s method and was counted for sucrose. When the dough was prepared using
accelerated technology, the improver affected the sugar content in the bread due to the starch
enzymatic hydrolysis. The effect of improver dosages and sugar dosages on the sugar content in
the bread was established. When using the improver, the sugar content exceeded the permitted
amount in 1.25 times. No correlation was found between sugar dosage in recipe and bread quality
when accelerated bread making way was used because of short fermentation time. The influence
of wheat flour amylolytic activity (falling number) on the sugar content in bread was established,
including when sugar was absent in the formulation. When sugar presented at bread formulation,
the flour amylolytic activity did not significantly affect the bread quality, except the acidity. The
bread making way had a greater influence on bread quality than falling number of flour. When
sugar absent at bread recipe, the higher was the flour amylolytic activity, the higher was the sugar
content in bread made by traditional way due to the starch deterioration. Obtained data have
shown that when a baking method is selected, the flour amylolytic activity must be taken into
account
Magnetic properties of ferrofluid emulsions: The effect of droplet elongation
The paper is concerned with a theoretical explanation of the experimentally observed effect of non-monotonic field dependence of the effective magnetic permeability of ferrofluid emulsion. In a weak magnetic field, the growth of the induced droplet magnetic moment is faster than the linear one due to the droplet elongation accompanied by the reduction of the demagnetizing field. Thus, the emulsion magnetic permeability increases in weak magnetic fields. Further strengthening of the external magnetic field cannot lead to a significant decrease of the demagnetizing field, as the droplets are already highly elongated. On the other hand, the magnetic susceptibility of the ferrofluid reduces with the field strength. Hence, the effective magnetic permeability of the ferrofluid emulsion starts decreasing. The developed theoretical model describes well the experimental observations
Impact of using the developed starter culture on the quality of sourdough, dough and wheat bread
ArticleThere is no technological necessity of sourdough usage when preparing wheat bread
as it can be prepared without sourdough but only with yeast using. However, sourdough helps to
solve such problems as fast microbial spoilage, unexpressed taste and smell, crumbling crumb.
The use of sourdough prepared with directional cultivation of microorganisms allows to produce
high-quality competitive bread. Developing a starter culture with an optimized microbial
composition was the purpose of this study, allowing the quality and the microbiological stability
of wheat bread improving. A new starter microbial composition for the sourdough was developed.
Lactic acid bacteria strains L. plantarum Е90, L. brevis Е120 and yeast S. cerevisiae Y139 were
selected for the new composition. It was proven that the rice products using to microorganism
immobilization allows saving the largest number of living cells after drying and during storage.
The rate of acid accumulation in sourdough was established. The sourdough dynamic viscosity
decrease at the end of fermentation by 2.2 times was established, which means that the
fermentation process leads to the sourdough liquefactio. The optimal dosage was established
(5–10% flour in sourdough). This dosage provided good physico-chemical and organoleptic
quality indicators of bread. It was proved that the sourdough usage allows getting good-quality
bread even when the flour with unsatisfactory amylolytic activity (high drop number) is used.
Slowing down the microbial spoilage in sourdough bread was proven. In general, the developed
sourdough wheat bread biotechnology improves bread quality and its resistance to the ropy-bread
disease
Rowan powder based acidifying additive acidifying additive - an alternative to sourdough in the rye-wheat bread production
Rye is an important part of the cereal food culture in the Russia and Nordic, Baltic and
Eastern European countries. Rye bread is often made of whole-grain flour using long-time
sourdough. In Russia, rye bread began to be produced less and less often due to the complexity
and duration of its technology. Therefore, the development of fast, natural and safe technologies
is relevant. The aim of the research was to develop a nutritional acidifying additive based on plant
materials (rowan powder, botanical species Sorbus aucuparia) for accelerated rye-wheat bread
technology. With an increase in the new plant additive dosage above 3.5%, the dough lifting
capacity deteriorated. The bread specific volume and the crumb compressibility deteriorated
when additive dosage was higher than 3.5%. It all may be due to the acidity suppression of yeast
activity in the dough. Taste and smell was also better in bread with new additive due to the rowan
powder chemical composition. The optimum dosage of new additive rowan powder in rye-wheat
bread formulation was 3.5% by weight of the flour. Usage of new additive with 0.1% of sodium
diacetate allowed slowing down moulding. New acidifying with rowan powder allowed to create
accelerated rye-wheat bread technology and to get bread with high consumer properties
About the need of organization of clinical examination of young people with small developmental heart abnormalities.
Due to the significant increase of complications developing in young people suffering from low cardiac abnormalities, detection of this disease is important. The aim of the study was to analyze the prevalence and structure of cardiovascular diseases in persone aged 18-21 years who have referred to the medical center of Dnepropetrovsk Medical Academy in the period from 2012 to 2013 in order to determine the mode of physicol exercises. We examined 268 students of 1-2 courses of medical academy, who, along with the clinical examination underwent standard echocardiography 2 times a year. It is established that in the structure of cardiovascular diseases in the studied group small anomalies of the heart occupy the first place; valve pathology the second place. In the structure of small abnormality of the heart, mitral valve prolapse is detected the most frequently. Since this anomaly affects the level of tolerance to physical stress and can lead to heart disorder, routine screening of patients with this disease is mandatory and must be carried out to address the choice of the level of physical activity
Limitations of the classical phase-locked loop analysis
Nonlinear analysis of the classical phase-locked loop (PLL) is a challenging
task. In classical engineering literature simplified mathematical models and
simulation are widely used for its study. In this work the limitations of
classical engineering phase-locked loop analysis are demonstrated, e.g., hidden
oscillations, which can not be found by simulation, are discussed. It is shown
that the use of simplified dynamical models and the application of simulation
may lead to wrong conclusions concerning the operability of PLL-based circuits
