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
Requirements to instruments of diagnostics of
external and internal environments of the
organization are developed and proved in this
article; comparative analysis of requirements is
carried out, incompleteness of the analysis and its
insufficient reliability are present, the problem of
need of improvement of instruments of diagnostics
is investigated, interaction model "the organization
– the external environment" with emphasis on
structurization of factors meso environment and on
the integrated model of process of strategic
management is offered, implementation of the
procedure of expert poll in combination with
estimates during the NDPESTEL –, SNW - SWOT
– and VRIO analysis, and also development of the
automation equipment which are used in the
interactive mode are offered
In the article, there were determined the physiological parameters of resistance of stocked plants to in-creased pH soil. There was shown, that the resistance of apple-trees to the action of edafic stress-factors achieved in the case of their grafting on average-growing clone stock MM 106
In the article, the methods of economical responsibility division of executives for delays of finishing of construction are presented, based on schematization of substitution and consideration invariance of profit norms for investment capital
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 subject of the research is a complex of high-tech manufacturing companies integrated and functioning in the form of project-oriented companies that are complex dynamic systems with increased efficiency due to changes in its structure and functions, institutional adaptation or use of project management techniques and optimization. The article reveals peculiarities of assessment methods financial performance knowledge-based project-oriented businesses, the main of which is that companies consider their activities as separate independent projects, which have their cost centers and profit. The author's solution to the problem of choosing the optimal investment project among several possible within the framework of the investment program or portfolio of projects, which can be mutually independent of each other, or mutually interdependent. The aim of the work is to study the possibilities and prospects of organizational and economic mechanisms for the use of project campaign for the effective management of knowledge-based enterprises that will quickly adopt new technologies and create optimal production structure. The results will be useful for the public authorities responsible for the development of high-tech industries as well as public and private companies wishing to profitably participate in the implementation of major innovative projects and programs. In the course of the study suggested methods for evaluating the effectiveness of high-tech project-oriented businesses, allowing them to identify the main advantages and disadvantages in meeting their specific production problems
Growing of crowning yearlings in garden nursery depends on elements of agricultural machinery, which have different effects on the angle of divergence and the number of skeletal branches formed. With the reduction of the period of growing branched yearling costs are lower for planting material, because of exception work in the nursery with two-year seedlings
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
