Waterflooding helps in the recovery of great amount of
oil that would have otherwise been abandoned in the
reservoir that is depleted. A reservoir in the Niger
Delta, Reservoir X has been used to illustrate this.
Reservoir X had oil initially in place as 7.345 MMSTB
and was produced for some time with the reservoir
natural energy. The remaining oil in the reservoir as at
the time that the natural energy of the reservoir was no
more sufficient to produce oil was 2.96MMSTB. The
reservoir has been left as depleted reservoir with the
remaining oil in it. But from the analysis conducted in
this work it is seen that if secondary oil recovery
project by waterflooding is embarked on the reservoir,
part of the remaining abandoned oil would be
recovered. With the specifications given, about
1.22MMSTB of the 2.96MMSTB of oil in reservoir X
would be produced as at the breakthrough time of 580
days. Moreover, considering the economic aspect of
the project, reservoir X and is good to be invested in.
From the NPV calculations performed, it is seen that
the NPV of reservoir X at discount rate of 10% is
$4.13 million
Car license plates recognition problem is one of the
typical tasks of computer vision. Video surveillance
software usually provides license plates recognition
function. Meanwhile, there are many approaches to
solve this problem, where template-based methods are
the most common. Such methods providing predictable
and short enough execution time, and little percent
of mistakes. However, such methods are far less effective
in case there is a need to recognize car’s license
plate, which may be located in unpredictable place,
typed in undefined font and on non-standard background,
or without strict formatting. For example,
USA car license plates. One of the methods to increase
effectiveness and quality of such license plates recognition
is to use neural networks. It is assumed, that
neural networks usage can significantly increase
recognition quality. Nevertheless, neural networks usage
entails difficulties of it’s training, and often becomes
less efficient as template-based methods usage.
This article discusses probability of usage of convolutional
neural network, which was trained using MNIST
(Mixed National Institute of Standards and Technology)
database. This article is a review of usage of templates
and neural networks for car’s license plate
recognition in terms of quality, performance and complexity
of the usage
The article reveals issues concerning three years
research about the rate of influence complex
water soluble fertilizers in seed treatment and
treatment vegetative plant in phase 3-5 and 7-8
leaves for grain yield increase. In the process of
research were determined summarized water
consumption and coefficient of water
consumption, measuring of morphological signs,
were given economical estimation of using
complex water soluble fertilizers in corn grain
yield increase. The research shows the efficiency
of seed treatment of average corn hybrid
Krasnodarskiy 377 AMV by complex water
soluble fertilizer Lignohumate potassium at dose
0,5 l/t. Grain yield increase in mentioned variant
was 4,4 c/ha in comparison with variant of
distilled water treatment. The same grain yield
increase was got by using in seed treatment the
mixture of Albit, 0,05 l/t with Lignohumate
potassium, 0,5 l/t. the treatment of vegetative
plants in phase 3-5 leaves when were sowed non
treated seed were less efficient than in phase 7-8
leaves, where grain yield increase was 4,5 c/ha.
Seed treatment of Lignohumate potassium in
combination with vegetative plants treatment in
phase 7-8 leaves by using Megamix, Bionekskemi
and Lignohumate potassium allowed to get
grain yield level 80,3-80,8 c/ha
The article presents results of the six-year study of the
effect of stocks Berlandieri × Riparia Kober 5BB and
Chasselas × Berlandieri 41B on yield, quality of
grapes and wine Rkatsiteli in the central zone of the
Krasnodar region. Effect of stock on the scion strongly
depends on the annual weather conditions. In a given
year, there is a stock, better adapted to the weather
conditions. Stocks of Chasselas × Berlandieri 41B
increases winter hardiness variety Rkatsiteli. On
average, during six years the stocks have not been
resulted in significant difference between the
percentages of developed into shoots buds and fertile
shoots shown in the coefficients of fruiting and
fruitbearing shoots Rkatsiteli. Among all the
influencing factors, the degree of influence of stocks is
0.1-0.4%. Some differences in forming of generative
organs of wintering buds along the fruiting twig under
the influence of stocks do not lead to significant
differences in biological terms of fruiting varieties in
the whole piece. On average, six years of significant
difference in the effect of stocks on the average weight
of the bunches, and the yield is not defined - the
degree of influence of rootstocks on mentioned
indicators is 0,1-2,1%. A significant impact of stocks
on the dynamics of sugar accumulation in berries has
not been discovered. The degree of influence of
stocks on to the final sugar content and acidity of
berries is 0.3 and 14.5%, respectively. The wine
produced from Rkatsiteli berries on a stock Berlandieri
× Riparia Kober 5BB has the better tasting score than
on the stock Chasselas × Berlandieri 41B (7.5 and 7.4
points, respectively). The main influence on fruiting of
the variety Rkatsiteli was provided by the conditions
of the current and previous vegetation. Within the
conditions of the central zone of the Krasnodar region
the cultivating of the variety Rkatsiteli is reasonable
for both studied stocks
The present article is concerning with the research of
influence of new mineral additive «Koretron» in diets
for young pigs on meat performance. The mineral
additive «Koretron» adsorbs and removes mycotoxins
from the body and is the source of water-soluble
silicon, which is necessary for stable functioning of
intestine and stomach smooth muscles and for
improving of calcium digestibility. It is proved, that
the considered feed additive has positive effect for
animal growth intensity because it has contributed to
increasing of both total and relative weight gain of
young pigs on fattening. It is determined, that the
mineral additive «Koretron» has positive influence on
meat productivity of animals from the test group:
killing-out percent, hot carcass weight, rib-eye area as
well as weight and meat yield, fleshing index have
been increased. The considered mineral additive has
contributed to improving of chemical composition of
meat: the content of dry matter both in the average
meat sample and in the longissimus dorsi, content of
nutrients synthesized in carcass meat, energy value of
carcass meat, biological value of meat have been
increased. The data received during our test give
evidence of high bioavailability of water soluble
silicon in tested additive, which has activated
metabolic processes in the bodies of young pigs on
fattening and, as a consequence, the gain of their live
weight has been increased and morphological structure
of carcasses and meat quality have been improved
We review the critical ratio of shares of domestic and
imported sunflower hybrids in the region and the trend
of displacement of domestic hybrids in the Kuban region,
yields and gross harvests culture. The article reveals
a negative trend for the full displacement of domestic
hybrid seeds from the market in the Russian
Federation
The article discusses the effect of additional spikelets
in the variety of Bezostaya 1 on the realization of
productivity of the examined plants. We traced the
frequency of occurrence of multirov spikes and studied
the effect of this phenomenon on the productivity and
the main quantitative characteristics of the studied
plants. The article demonstrates the structure
distinction of productivity for abnormal and normal
ears. Experience was one-way vegetation, planted in
triplicate, time of experiment - 2013 - 2015 years.
The study revealed that the most frequent was the
emergence of 1-4 additional spikelets per spike. Some
quantitative characters had a slight deviation, these
include the number of spiked ledges on the kernek,
spike length and plant height. To a large extent we
increased the characteristic values such as the number
of grains per ear, number of spikelets per spike,
number of grains onto the ledge, head weight and the
weight of grains spike. We significantly reduced
weight of 1000 grains. It was revealed that more
localized spikes were mostly in the middle, the most
productive part of the ear. As a result, changes have
affected not only the quantitative characteristics
related to the productivity of the ear, but also its
architectonic whole
The study was carried out during 2010-2015 years in the
All-Russian research Institute of Grain Crops named
after I.G. Kalinenko (the laboratory of the cultivation
technology of plowing crops), situated in the southern
soil-climatic zone of the Rostov region, which is characterized
with the unstable and insufficient humidity. The
trials were conducted on the heavy loamy, calcareous
chernozem obyknovenny (natural blacksoil). The object
of the study was the grain sorghum variety ‘Zernogradskoe
53’, approved to use in the Rostov region. The agroclimatic
conditions during the years significantly differed
during the vegetation in the amount of precipitations
(from 110.2 mm in 2010 to 200.2 mm in 2013) and
in the temperature regime (from 2512.9 0С in 2010 to
2788.8 ºС in 2015), that allowed evaluating the grain
sorghum productivity more objectively. The article gives
the study results of the effect of the weather conditions
on the duration of vegetation, productivity and grain
quality (content of protein, oil, ash and fiber). The article
showed the estimated interconnection among the sum of
active temperatures, precipitations and hydrothermal
coefficient during the sorghum vegetation with the principal
economic-valuable traits of grain sorghum. The
sum of active temperatures showed the greatest effect on
the duration of the vegetation (r=0.89); the sum of precipitations
during the vegetation had the greatest effect
on the productivity (r=0.80). There was determined the
strongest positive correlation of the sum of active temperatures
with the content of protein in the grain sorghum
kernels (r=0.80) and the average negative correlation
with the content of oil (r=-0.69). The sums of active
temperatures and precipitations, when the grain sorghum
gives the largest productivity, were established
The aim of the research was to study the impact of
starter complete feed (CF) with different levels of
crude fat on the chemical composition of muscle tissue
and liver of young geese. During days 5-28 the poultry
was fed CF with 5.1-8.1 % crude fat, from 29- to 60-
day age – with 5.4 %. By increasing the level of crude
fat in starter CF there was a trend to an increase of the
phosphorus content in muscle samples of geese hip
and thigh - by 4.4-9.6 %, in the liver - by 27.2-53.5 %
(P≤0,05). The chest muscles of the young geese fed
high-calorie CF had 2.8-6.0 % higher fat content, than
that of counterparts in the first group. At the same
time, there was a tendency to a decrease in the
concentration of fat in the muscles of the hip and thigh
- by 1.9-5.0 % (P˃0,05). Increased level of crude fat in
CF did not have a negative impact on the accumulation
of heavy metals in the muscle and liver of geese, the
concentration of the studied elements was within the
permissible level established for food products
The article presents the analysis of variation of daily
mean temperatures for the period 1977-2015. Clear
tendency for their increasing in pre-sowing and
especially in growing period is found. Heat supply of
separate months in pre-sowing period increased in the
row: April-February-January-December-March, and
that of growing period – in a row: May-Juny-JulySeptember-August.
Presence of slight correlation
(from -0,256 to 0,268) of temperatures in winter-spring
months with heat supply of coming spring summer
months is found. It is shown that correlation of rice
yield with temperatures of pre-sowing (DecemberApril)
and growing (May-September) periods varies
from weak to average (from 0,016 to 0,524) with a
tendency to increasing from winter months to summer
ones. Use of analog method made it possible to
estimate roughly the nature of t upcoming growing
season of rice in the current 2016: after the abnormally
warm winter one should expect the value of heat
supply of summer months to be close to normal. In the
physiological sense, such distribution of summer
temperatures is favorable for rice. Use of one of the
most effective forecast methods – smoothing the time
series (method of «moving decades») – made it
possible to evaluate medium-term rhythms of heat
supply of rice growing season and yields. It was found
that after an abnormally high level of heat supply of
the growing season, marked during last decade, we
should expect a decrease in spring and summer
temperatures - the next attack of the "cold" cycle. If
this hypothesis is confirmed, then up to 2020, and later
a natural tendency for decrease in rice yields, arising
from the adverse factors of temperature, will continue
which should also affect the economic efficiency of
the industry as a whole
