RESEARCH OF THE DEVELOPMENT OF CONSTRUCTIVE CONFIDENCE OF STUDENTS-DESIGNERS WITH MEANS OF FINE ARTS
This article is about researching of the pedagogical experiment based on introduction of author's technology of development of criteria of constructive confidence of students-designers with means of fine arts, such as an adequate self-estimation, social boldness, self-reflection, self-control and visual skills of communication
The comparison of the quality of the processing of surfaces of shafts made of various materials with cold and hot deformation in the repair of worn-out parts of agricultural machinery has been made in the article. The technique of the experiments was proposed. The effect of the treatment regimes on the quality of the surface layer (surface roughness) of the details was examined
The article presents the results of the research of the
influence of preliminary treatment of garden beet roots
with electromagnetic fields of extremely low frequency
on the loss of dry and biologically active substances,
such as vitamin C and P-active substances, in the
process of long term storage. Garden beet roots of
Bordo 237 variety were the objects of research. The
objects of research were stored for 7 months at a
temperature of 0…+1° С and relative humidity of 90
%. Sampling was carried out every month during the
entire storage period. The treatment with
electromagnetic fields of extremely low frequency was
carried out using an experimental setup of our own
assembly. As a result of the conducted research it is
established, that the treatment of garden beet roots of
Bordo 237 variety with electromagnetic fields of
extremely low frequency before dispatching into
storage allows to decrease the losses of dry substances
by 4,1 % by the end of the 7 months storage period, and
also to decrease the losses of vitamin C by 14,8 % and
P-active substances by 15,1 %. The data obtained can
be used to develop new or improve existing
technologies of garden beet roots storing
As a result of the analysis of the scientific question, there is a steady trend of growth in food consumption, especially of plant origin. To this issue, it is also necessary to add the provision of food security of the country and the exclusion of dependence on foreign producers. Thus, before science and production is a serious question of a significant increase in the production of crop products with a slight increase in the cost of these types of work and the main thing is to ensure the preservation of soil fertility. This can be achieved by reducing the use of chemical means of protection, less intensive impact on the treated environment by the running systems of power facilities and the working bodies of machines, but in compliance with the primary requirements for the treated surface. The proposed design of a horizontally arranged spherical disk working body can be used in various tillage machines for shallow and surface tillage. The design of the working body allows reducing the passes of the unit to perform the necessary agricultural requirements for equalization and ridges of the soil. And these indicators have a significant impact on the quality of sowing, which will necessarily affect the yield in the end. Comparative studies of the proposed working body and the same devices used in production show a clear advantage of the new scheme
The object of the article is to consider the surrounding factors of city passenger motor transport of the municipal union «City of Magadan» and to estimate the degree of their influence to municipal transport infrastructure by means of the PEST-analysis, SWOT-analysis, a method of pair linear correlation, and a method of profile city surroundings. As a result of this analysis, the basic directions of the strategy of city passenger motor transport development are defined, some recommendations improvement of management efficiency by public transport from the institutions of local government are made
A selection of food additives for the enrichment of
waffle products was made. Food additive "Powder
from tubers of Jerusalem artichoke" is distinguished by
a high content of inulin - 46.21%. Low-fat sunflower
lecithin contains a significant amount of phospholipids
(98.29%). The influence of the joint application of
food additives "Powder from the tubers of Jerusalem
artichoke" and nonfat sunflower lecithin on the
technological properties of the wafer test was studied.
It is established that the introduction of the food
additive "Powder from the tubers of Jerusalem
artichoke" together with defatted sunflower lecithin,
instead of the traditional soybean, allows to reduce the
viscosity of the wafer test. When introduced into wafer
dough, the dosage of defatted sunflower lecithin can be
reduced, compared to soybean, from 0.4 to 0.2% by
weight of flour
We have experimentally studied fluctuations of power of an electric arc in different types of plasmatrons with different power supplies in the article. Influence of fluctuations of power of the plasmatron on technology parameters of a plasma stream (current, voltage, an enthalpy, temperature, speed of a plasma flow) and on process of forming of coatings at impulse plasma was experimentally shown that the nature of fluctuations depends from fluctuations of voltage of the power supply, plasmatron type and also from fluctuations of an electrical arc. The size of fluctuations of power can be 50-100%. It is experimentally shown that impulses of power of an electric arc are capable to complicate supply of sprayed powder in to the plasmatron. Such fluctuations do not make dispersion of the melted powder particles. In the work, we have drawn conclusions that large-scale pulsations are capable to worsen quality characteristics of plasma coatings significantly
In the article we consider the questions of ozone and air impact on pathogenic microflorastern of products when their production. Results of the statistical analysis allowing to determine optimum parameters of influence of ozone and air mixture at sterilization stern of products are also presented
The article presents: the results of experimental studies of the influence of parameters on Escherichia coli ozonation and Staphylococcus aureus, the optimal parameters of ozonation hive on the criterion of minimum energy intensity of the treatment
The article presents the results of a study of the influence of the processing method before storage on the commercial quality of carrot roots during storage. The object of the research was carrot of the Abaco variety. Objects of study were stored for 21 days at + (25 ± 1) ° C and 56 days at + (2 ± 1) ° C. Roots were treated with extremely low frequency electromagnetic fields (EMF ELF) and Vitaplan biopreparation separately and in combination. As a result of the research, it was established that the complex treatment of EMF ELF and biopreparation allows increasing the yield of standard carrot products compared to the control: 11.8% at storage temperature + (2 ± 1) ° C, 24.1% at storage temperature + (25 ± 1) ° C. A reduction in the total losses of carrots, treated with complex EMF ELF and biological product, was found by 5.8% at storage temperature + (2 ± 1) ° C and by 12.4% at storage temperature + (25 ± 1) ° C
