Works of painters of past is the source of information of crop domestication, use in horticultural, species diversity. Lagenaria crop images in painting can also be a resource for determining the morphological changes of the crop in evolution
The article analyzes the phenomenon of non-daily handle as an alternative of impersonal being of Dasein, whose inner definition is not the canonic being-to-death but creative being-in-the-world that goes over existent finiteness of Dasein
МF-4SК membrane-based microbial fuel cell (MFC) was used for an anaerobic utilization of organic com-pounds of various liquid wastes. During incubation in short circuit mode, decreasing of the COD value on range 30-87 % depending on the type of wastes was detected. The dependence of the microbial fuel cell output power on the value of the external load was determined by a number of structural characteristics of MFC
The article contains a scientifically based approach to
assessing and improving the reliability of DMU "Frigate"
in the conditions of the Rostov region. The studied
parameters for the elements with the lowest resource
were: mean time between failure, mean time to repair,
probability of failure, the parameter flow of failures,
failure rate, actual and allowable factors of readiness.
The analysis of the main faults of DMU "Frigate",
identified nodes and elements, characterized by the
low reliability, for which the dependences of probabilities
of failure-free operation, as well as the dependence
and developed the procedure for calculating the optimal
duration of recovery of failed elements, to ensure
acceptable availability. Statistics on major faults refuse
items were collected over the three irrigation seasons
from 2013 to 2015, were investigated failures due to
wear of the elements for 17 irrigation machines. As a
result of the research we developed mathematical apparatus
of calculation and the comparative assessment
of the readiness of the parks sprinklers of various
farms to perform their processing functions at the same
and different number of machines. We obtained the
dependence for determining the allowable duration of
the recovery elements that will allow you to determine
the main directions of improving the reliability of
DMU "Frigate" during the operational phase
In Russian civil legislation the consumer is a citizen
who concludes the contract of retail sales for purposes
not related to business activities. Incorporated person
has no right to conclude a contract of retail sales.
Therefore the law on consumer protection is not used
for legal entities. The law on consumer protection gives
to consumers an opportunity for simplified procedure
to challenge acts or omissions of the sellers and
protection of their rights. But at the same time the
incorporated person may acquire the goods, works and
services not for business purposes. In particular, this
occurs when incorporated person buys goods for its
professional aims, not just for its implementation. The
authors think that legislator unreasonably violates the
rights of legal entities, because they can not be
consumers. The authors justify the possibility and the
necessity of recognizing the incorporated person as a
consumer in the contract of retail sale, and that will
allow spreading the legal norms of consumer protection
on them
AN EXPERIMENTAL RESEARCH OF THE SMALL BIOREACTOR WITH THE BUBBLE MIXING SYSTEM AND CATALYTIC HEATING
The article reviews the results of an experimental research of a small bioreactor with bubble mixing system and catalytic heating. The methods improving the efficiency of biogas plants are considered there
The main characteristics of a transport network are the intensity of the traffic flow, speed and density of its traffic. Comfortable driver's traffic density is determined by the rule of the traffic police, which is "clearance between cars on the road should be a tenth of the speed of movement." We have built a reference curve of the density function of the flow of vehicles on its speed, which is basic when simulating a traffic flow. The article describes a model of electrical city transport networks, allowing calculating traffic flows, their speed, the density and the number of traffic lanes by means of laws of electrical engineering. We have also compared electrical concepts (current, resistance, electro-motive force, etc.) and transportation (of intensity-flow lane road, transport driving force, etc.). For the transport network there are methods of calculation of electrical circuits - a method of Kirchhoff's laws, loop currents, etc. We have confirmed the correctness of electric models and the possibility of its use for the calculation of transport networks; as well as we have presented an example of the calculation
Classical combinatorial formula to calculate the number
of combinations from n on m: C(n,m)=n!/(m!(nm)!)
involves the intermediate calculation of factorials,
which is often impossible when n>170, due to limitations
in the capacity of numbers that are used in programming
languages and created through these systems.
However, in some cases it is necessary to calculate
the number of combinations for n and m much
larger than this limit, such as when a value greater than
10000. In such cases, there is a definite problem,
which manifests itself, for example in the fact that
many on-line services meant to calculate the number
of combinations with these parameters do not work
properly. In this article, we present its solution in the
form of an algorithm and software implementation.
The essence of the approach is to first decompose the
factorials into prime factors and reduce them, and then
to produce multiplication. This approach differs from
those cited in the Internet
The article is dedicated to a numerical investigation of
a plane problem of the oscillation amplitude of a
buried source, depending on the frequency and motion
speed in various isotropic media. Three types of the
medium are considered: a two-layer package with a
rigidly fixed base, a two-layer package with a
mechanically free base, a half-space. The source, in the
form of a stress jump simulating a rigid inclusion of
small dimensions, moves in the interface plane at a
constant speed. Homogeneous boundary value
problems are considered in a moving coordinate
system associated with a source. The solution method
is based on the usage of integral Fourier transforms,
the method of direct contour integration and
algorithms for constructing symbols of Green's
matrices. The method of direct contour integration
significantly simplifies calculations in comparison
with the traditional approaches to the calculation of
Fourier integrals. We have presented calculations of
nine amplitude-frequency and amplitude-velocity
characteristics for different combinations of medium
and source types, that give an exhaustive qualitative
and quantitative description of the solutions for
boundary value problems in a wide range of velocities
and frequencies. Comparative analysis of calculations
showed a primary influence of the type of an elastic
medium on the investigated characteristics, as well as
the large influence of the source type. Which, in turn,
revealed some substantial connections between the
boundary value problems with a moving source and
the corresponding problems with a stationary source
The report, presented by 18-20.09.2012 in Gaylvaylerhofe / Germany at the European meeting of Ampelography ECPGR in international cooperation of the COST project, provides the information about the collection, the study and the storage of wild grape vines, as well as indigenous and selected varieties in the National ampelographic collections of Russia, nowadays containing 3,220 specimens of 42 countries, 191 of which were oppressed with phylloxera. The modern zoned assortment of grapes in Russia (according to the State register of breeding achievements of the Russian Federation) with the most common areas of local and introduced varieties is examined. The summary of the impact of the clonal selection of the classic industrial engineering classes, conducted by the author’s original technique, as well as the achievements of combinative breeding of the actively breed resistant varieties is given. Moreover, their reproduction at the level of selected protoclones or elite breeding forms (candidate variety) was conducted with in vitro method
