Damage of grain and seeds by machines makes
essential negative impact on sowing qualities of seeds
and processing properties of grain. While processing of
grain a lot of various cars and actions differently injure
weevils. To exclude traumatizing of grains in the
course of mechanical preparation is not obviously
possible, as working bodies of cars are a source of
mechanical and thermomechanical damages. Besides,
injured weevils on the physical-mechanical properties
practically do not differ from whole, i.e. they do not
possess signs for machine division. To reduce
traumatizing of weevils is possible with the help of
application of optimum technologies of machining,
selection of the conforming technological modes, using
as a part of actions of constructional stuffs with a low
elastic modulus, perfection of their design data. For
definition of injuring ability of various machines and
actions through which takes place grain lots, have
developed a procedure which allows with high degree
of reliance to estimate complex traumatizing of weevils
(namely, their outside integuments and intrinsic
frames) machines and the actions which are a part of aggregates and complexes for machine preparation of
grain and seeds. The developed procedure bases on a
basis of the standard documents regulating test
methods of agricultural machinery and together with it
allows to consider connatural heterogeneity of the grain
lots arriving for processing
The article presents a review of the existing methods for the determination of crotonaldehyde in food. The necessity of this component in the control of food products, including wine, is visible because of its toxicity and the probability of formation during microbial synthesis and chemical transformations. The
article describes the developed qualitative method of determining the content of crotonaldehyde in table wines with spectrophotometry
The article describes the basic techniques for working
with Kontrol automated monitoring system. We suggest
the algorithm for creating and editing test databases,
software settings-governmental applications,
technologies used in the tests of text, graphics and
multimedia data
Condition monitoring is a necessary element of the
transport and special machinery in agriculture. The
task of the control operations other than the
determination of the technical state of the object is to
determine the required amount of work, as well as
rational amount of collateral the repair of which could
be combined with the next maintenance. Based on the
results of processing of the information, we may
generate requests for service. In the conditions of
uncertainty of receipt of requests for servicing of
individual machines, estimated volumes and timing,
we have am appropriate development of applied
technique of justification of the number of diagnostic
posts for interactive control of a technical condition
of vehicles and special machinery in agriculture. The
presented methodology is based on probabilistic
methods, and allows the quick optimization of the
number of existing posts interactive diagnostics in the
enterprise, if necessary, translating the existing posts
in "standby" mode, or Vice versa, returning from a
reserve in "work" mode. The production and
technical base of the enterprise service based on the specific assumptions are considered as a system of
mass service (SMO), and the function of such a SMO
– as the process of mass service. The process of
queuing as applied to interactive diagnosis are
"Markov" processes "death and reproduction" with a
finite or countable number of States and continuous
time. To describe the states of the system we use the
system of the Kolmogorov equations for steady state
of "Markov" process. On their basis, we have
determined average queue length, time of stay orders
in the queue, number of busy channels and the
bandwidth of the CFR. Using the intensity of the
requests and the service time of a single application
for specific equipment, the article establishes the
efficiency of online diagnosis posts. The result of the
proposed applied methodology enables timely
decision-making about the need for reconstruction or
technical re-equipment of the company
The article presents the methods of efficient monitoring rate of the mobile agricultural equipment brake system based on the usage of methods of the theory of relativity. We have considered the methods of the brake gear monitoring rate according to the acceptable level of reliability, to the technical index and change logic of the technical parameters state and economic-probabilistic method. From the above-stated one can see, first, that diagnosing usage is the development of maintenance preventive strategy. Second, its practicability and the ways of realization are determined by technical and economic calculations
The competitiveness of any company engaged in the
wholesale or retail sale of goods and services is
substantially determined by the level of quality of the
services provided. For the accompanying business of
vertically integrated oil companies, the criterion of
quality service is not an exception. Currently, cafes
and shops at the refueling complex are not only a
convenient service for customers, but also a solid
source of additional revenues for the largest oil
companies, each of which seeks to make the retail
network attractive to customers by offering a wide
range of goods in stores, ready meals in a cafe, and
related services. To satisfy the needs of the client, it is
necessary to offer a wide, but rational assortment of
goods at the refueling complexes. The claimed goods
must always be at the refueling complexes. The lack of
goods necessary for the customer on the shelf means
the loss of sales and profits, the order and location of
goods that are not in demand - the formation of
surpluses, returns to the supplier and write-offs. This
also affects the overall economic performance of the
company. In this regard, the increase of logistics
service is one of the priority tasks of the
accompanying business of vertically integrated oil
companies
The article describes the method of performing calculation the resultant drifting of pollution discharged into the sea as wastewaters of fishing ships. It presented formulas for discovering the drifting of ship’s waste water fields in the seaward districts of western Kamchatka. Results of calculation the wind’s summary vector at 50 km distance from the shore meteorological stations of western Kamchatka based on direction (compass point and degree) and average monthly speed are presented. The analysis of these results gives the conclusion that waste water fields from the ships could reaching western shore of Kamchatka and pollute it

In the research we have given a detailed description of certain structural components of the model system when adding fermented raw material into it. As the raw material we used collagen containing by-products of bovine animals of the 2nd category – lips and ears were used. The lactulose syrup and linseed flour were used as growth-promoting substances. The fermentation of the raw material was conducted by freeze-dried starter of the bacteria of Propionic Culture PS–4 and Probio–Tec ВВ–12, and also bacterial concentrate Bifilact-Pro. The fermentation parameters: the temperature 37°С, the time of the fermentation is 3 hours. The changes, taking place in the tissues under the biotechnological processing, were established with the method of the histological samples test. As the result of the conducted microstructure tests of prototypes it was determined that in the biomodification process under the influence of the propionic and bifidus bacteria marked changes occurred in the histological structure of modeling systems in the comparison with the control sample. At the same time it was ascertained that under the influence of the ferment processing a loosening of collagen fascicles happens to isolated fibrils and their fragmentation occurs. As the result, when composing protein compositions an emulsion (which is homogeneous by the structure) comes out. In the future it is recommended to use the emulsion in the receipts of boiled sausages and minced half-finished goods
