The article gives a review and the experimental data on
the nutritional value of eggs protein comprising
protein, carbohydrates, minerals and amino acids.
Metabolism, the structure and function of each cell, as
well as external and internal protective functions are
defined by proteins. We consider the study of
functions of trace elements found in significant
numbers in the eggs, which contribute to health:
vitamin D, vitamin B12, choline, folic acid, selenium,
lutein and zeaxanthin. The high content of egg protein
contributes to greater satiety, weight loss and eye
health. We present experimental data on the amino
acid composition of the protein and experiments of
drying a cooked egg white, placed in a Petri dish.
After 10 minutes of drying, the weight of the protein
did not change and amounted to 0.1 g, which is 16% of
the weight of the original white protein. The photo
shows that the protein is lost during drying white and
became transparent, and protein grains look like
"melted" and partially connected with each other. The
data obtained can be used for understanding the
operation of the biological process of protein in vivo
The content of metals in raw rice is determined.
Inversion voltammetry (IVA) was carried out in an
accredited laboratory on the "Ta-Lab" device of the
company "Tom-Analit" LLC according to the
approved method of ERD F 16.1: 2: 2.2: 2.3.46-06.
Silicon dioxide is determined according to ERD F
16.1: 2: 2.2: 3.65-10 and humidity according to GOST
5180-2015. Preparation for the IVA is illustrated.
Voltammograms of the potential difference of the
chloride-silver reference electrode are compared with
the current strength of the indicator mercury-film
electrode of electrochemical cells. It has been
established that the main metals of the raw rice called
Regul grown in the Krasnodar region are: copper 1.6 ±
0.4 mg/kg, plumbum 1.4 ± 0.4 mg/kg, zinc 1.9 ± 0.5
mg/kg, iron 95 mg/kg, manganese 5.2 ± 1.3 mg/kg and
silicon dioxide 6.5 mg/kg. The presence of iron is
associated with the wear of gravity. The content of
zinc, manganese and silicon dioxide corresponds to
this type of grain. The presence of copper and lead is
associated with the absorption of heavy metals from
the soil
The article presents results of research on drying a
slurry consisting of distilled water and finely chopped
cooked chicken protein of table eggs. The suspension
is placed in a Memmert oven, which has temperature
of 60 °C. In the process of removing moisture when
drying the slurry of water - boiled protein we
examined kinetics of its drying and performed
chronological photographing of conformation of the
system of water - boiled protein. The final weight of
the protein remaining after evaporation, was 0.06 g
corresponding to 26% by weight of cooked protein
source in an amount of 0.23 g. The analysis of the
system appearance including the evaporation of the
water showed that the protein was originally white,
and this color does not undergo any changes until 35
minutes of drying, i.e. when the main base is water.
Upon further drying of the suspension, starting with 40
minutes, boiled protein literally "melts" in the
surrounding water residues; and as it is disappearing,
becoming more and more transparent. Meanwhile, the
forms of the protein are becoming round and
transforming into the form of liquid crystals. The final
phase of the protein is a solid transparent film
The flowsheet purification of exhaust gases in the
Novocherkassk SDPP after the electrostatic
precipitator on I-th stage of purification set group
cyclone, on the II-nd stage of purification - baghouse.
To determine the particle size distribution of fly ash,
we selected ash from the transport network to the
group cyclone, and the in a group cyclone, and in a
baghouse. With the help of the microscope "Biomed-
3" we produced pictures of ash particles with different
magnification. Granulometric composition of three
selected ash samples were determined according to the
mass content of particles of different grain size,
expressed in percent relative to the weight of dry ash
sample taken for analysis. For size fractions from 10
mm to 0.5 mm sieve method is applied without rinsing
with water, for size fractions less than 0.5 mm sieve
method is applied with water washing. The particle
size of the ash mixture, taken up before the cyclone,
The electric method of gas dedusting is the most
effective, since it allows capturing solid particles with
a size from 0.01 µm to tens of microns. The efficiency
of dust and gas cleaning equipment of Novocherkassk
SDPP for cleaning flue gases from ash at power units
1-7 in the period from February 2015 to February 2017
is considered. The main equipment is electrostatic
precipitators. As a solid fuel, Donetsk culm is used. It
is established that the efficiency of waste gas
purification at power units 5-7 was about 99 %, while
at power units from the 1st to the 4th this value was
within 95-96 %. The data obtained correspond to the
design data, but it is recommended that the cleaning
devices be improved to improve their efficiency. The
most acceptable is a combined electrofilter-bag filter
The power plant being investigated is Novocherkassk
State District Power Plant located in the settlement of
Donskoy, Rostov region. The power object is included
in the list of objects of the fuel and energy complex
subject to categorization and is defined as critically
important. The analyzed site is the "subsidiary farm",
which includes a chemical reagent warehouse and a
site for chemical water purification, where hazardous
substances are treated: sulfuric acid and technical
sodium hydroxide. The analysis of the main causes of
accidents at thermal power stations occurred during
processing, storage and transportation of hazardous
substances, and typical scenarios of possible accidents
at the chemical water treatment plant of thermal power
plants were considered
