The article provides information about the impact of the main methods of tillage crops on weed management component agrocenosis of winter wheat
There were determined the close correlation dependence
between the energy of propagation of wheat seeds sunk
in water in which the grape cuttings were rooted on one
side and the rooting and output of cuttings with three
roots and more on other side by the authors. There were
the equations of regression for prognosis of rooting and
output of cuttings with three roots and more
Method of replications amount determination under comparison of two samplings dependently on average values of samplings and their standard deviations is presented in this article. Example of samplings comparison by the criteria of Student has been shown.
The article is devoted to the method of selecting
quails. Intensive development of re-fishing requires the
development of breeding methods for selecting birds
and to carry out early predictions of egg production.
Targeted breeding selection is able to influence the
mechanisms of correlation dependencies between
individual parts of the animal's organism, significantly
change even firmly established interrelations, and
create new interactions more satisfying the needs of
the individual. The research task consisted of
establishing links between the parameters of the
skeleton and the productive qualities of the layers. The
studies were conducted on Texas white quails. We
took into account the live weight of the bird, the length
of the metatarsal and the third finger, as well as the
small and large diameters of the metatarsal.
Correlations were established between the length of
the pelvic limbs and the live weight of young quails
during growth. It is established that the growth of the
skeleton ends with the age of onset of puberty. This
provides a basis for predicting the live weight,
depending on the length of the pelvic extremities. It is
established that the live mass is directly related to the
egg productivity of quails. Thus, by selecting the birds
with the longest plus, it makes it possible for 25 weeks
of productivity to increase the egg laying on the initial
layer by 5,7 eggs and 6,2 eggs per average laying hen,
respectively
The issues associated with visualization images of the examined object and the method of sketches or visual notes have been discussed in the article. The images of lagenaria (bottle, shape pumpkins or gourds) in works of art and agrobotanic illustration as a research tool have been selected, with the aim to conduct a visual analysis of the morphological characteristics of bottle gourd for further application of the knowledge gained in archaeogenetics and plant breeding. The article presents images of plants of lagenaria for the period from 1311 to 2014 years. Visual analysis of the morphological characteristics of lagenaria on the basis of visual notes allowed us to identify several key points: the polymorphism of fruits and different duration of the vegetation period, particularly of the reproductive system, which is characterized by different proportions of male and female flowers, the presence of pollinators, night flowering, fruit pubescence on the first stages of development, polymorphism seeds, features maturation based on the size and weight of the fetus. Understanding the range of individual development allows the breeder to submit a complete selection issue, search for new signs will touch the ancient forms of the object, diseases, pests, images which have remained only on the pictures. In our opinion, the method of visual notes can be successfully used in the educational process because it stimulates creativity and cognitive activity of students to search for information about the studied object and its reflection
In the article, the structurally functional method of the search of the defects in the segment of the computer network is considered. The basis of this method makes: the structurally functional model of a network; the table of malfunctions; the vector of checks with the obvious address of the knot of the network
In the article, the method procedure, allowing to define the amplitude of a switching overstrain is described when switching by the solenoid starter of the asynchronous electric motor
The expediency of the application of simulation modeling as an instrument of assessment of the production and financial risks of innovative projects in agricultural sector is proved in the article. Economic efficiency and risks of investments in introduction of innovative technologies of sunflowers preprocessing are analyzed
To the present stage, the process of becoming contract soldier professionals lasts up to 10 years or more, which is impermissible for the Armed Forces of the Russian Federation. One of the elements of a professional orientation of soldiers under contract is its evaluation. In the study, the authors have proposed evaluation methodology of professional orientation of contract soldiers. The validity and reliability assessment of the proposed methodic was carried out in two stages: stage 1 - respondents survey according to the methodic of M. Rokeach and getting their individual profiles; stage 2 - predicting the level of respondents professional military orientation, based on the assessment of proximity (conformity) of the respondents' individual profiles of value orientations to owned reference profiles. The evaluation of the internal (criterion) validity technique was performed as assessing the validity of the relationship between the influence and the observed results and the possibility to use this relationship to predict respondent's actions in future. Reliability of the methodic was assessed by three indicators. For all the indications we have obtained the results, showing the retest reliability of the proposed methodology of evaluation of military-professional orientation
In this article, we consider approaches to the transfer
of knowledge to students and an objective
semiautomatic assessment of knowledge. The
characteristic features of the application and the
possibility of using cognitive training methodologies
and complex systems for testing skills and the
theoretical base of trainees are analyzed. The
problems of development of this direction and
possible ways of their solution are described. The
basic concepts are introduced and the existing
methods of calculating the average score for
checking the student's knowledge are considered,
and a new approach to solving this problem is
proposed. Based on the conducted researches it is
offered to use the complex system of testing of end
users, which includes testing, monitoring, collecting,
analyzing and displaying the results of
students/groups/ course. The main requirements for
the creation of such a complex and the rules to be
followed are formulated for a more objective
assessment of knowledge. A model of an integrated
modular system for objective semi-automatic testing
of knowledge through testing is described
