The belief that intonation accuracy is a key determinant of musical performance quality is ubiquitous in music pedagogy; nonetheless, empirical validation of this belief is lacking. We investigated the effects of intonation accuracy on perceived performance quality and assessed whether music professionals’ beliefs about the importance of intonation are consistent with these effects. In Experiments 1 and 2, participants listened to vocal performances that were in tune, moderately out of tune, or severely out of tune. Only severe mistunings caused decreases in performance quality ratings for intonation insensitive listeners (those who performed poorly on a mistuning detection prescreening). However, both moderate and severe mistunings were detrimental to the ratings of intonation sensitive listeners. These results indicate that moderate mistunings exert a negative influence on the perceived quality of a performance only if the listener can explicitly detect the mistunings. If a listener cannot explicitly detect the mistunings, those mistunings do not implicitly exert a negative influence on the perception of the performance. In Experiment 3, music professionals heard samples of performances from Experiments 1 and 2 in each intonation condition and were asked to estimate the impact of the mistunings on listeners’ ratings of performance quality. Their predictions were compared to the actual performance quality ratings obtained in Experiment 2. Music professionals overestimated the impact of moderate mistunings for both intonation sensitive and insensitive listeners, suggesting that music professionals may hold inaccurate beliefs about the importance of intonation accuracy in vocal performance.

Significance of stocking density in broiler production i.e. production performance, vitality and health condition of chickens, was established at the beginning of development of industrial poultry production. However, considering intensive development of selection work and creation of more productive genotypes which, at the same time, were more demanding in regard to rearing conditions, the current importance of this research is not diminished. In favour of this statement is also the complexity of the effect of stocking density which is direct, indirect, and interacted with other factors of rearing, which eventually reflects on all aspects of broiler production: economical efficiency, quality of products and broiler welfare aspects. In the paper a review of research results is presented with general objective to define optimal stocking density in broiler production based on comparison of effects on production performances, parameters of carcass quality and indicators of broiler welfare.

The article is devoted to solving one of the most important problems of the development of the sugar industry in Russia – the modernization of sugar production processes. Today, sugar production is actively being modernized, shifting most of its processes to the path of avomatization and optimization to improve the quality of products. This article describes one of the main ways to obtain information about the concentration of sucrose in syrup in the production of sugar.

Приведены результаты исследований по изучению влияния промышленной технологии возделывания картофеля на развитие, урожайность и качество продукции. Выявлена положительная реакция растений на подкормку K2SO4 в период посадки. Корреляционно-регрессионный анализ урожайности и качества клубней выявил высокую степень достоверности результатов опыта. Содержание нитратов и тяжелых металлов в клубнях было ниже допустимых величин.The results of studies on the impact of industrial technology of potato cultivation on growth, yield and quality of products. There was a positive response of plants to fertilizer K2SO4 in the period of planting. Correlation and regression analysis of yield and quality of tubers revealed a high degree of reliability of the results of experience. The contents of nitrates and heavy metals in tubers was below the permissible values.

The introduction of the newest technologies of organic pig breeding has the basic principle of minimizing the use in pigs of chemicals, trace amounts of which in pig production adversely affect the quality of products and the health of consumers. The transition to herbal remedies, the maximum possible rejection of chemical synthesis products, is inhibited, in the main, by the relatively small spectrum of plant compounds with the investigated activity. According to the results of previous studies, six working solutions of Juglans regia L phytosupply extracts - potential phytosine disinfectants were developed: To investigate the bactericidal activity of the experimental preparations of Juglans regia, flushes were made from the internal structures and technological equipment of the housing of the pig stock of the experimental base v. Takhtaulove. Obtained samples of typical banal microflora of the pig complex were mixed to obtain a bacterial-containing suspension averaged over the concentration of microbial bodies and the spectrum of types of microflora in the microbiota. When cultured on nutrient media, with the superficial sowing of a suspension of banal microflora of a pig in the presence of a potential phytodisinfectant, processes of development of individual colonies of the microflora are observed. The amount and intensity of their development, the degree of inhibition of life, assess the level of bactericidal activity of the extracts. The highest bactericidal and fungicidal activity, and consequently, the potential efficacy as a possible disinfectant in the technology of organic pig breeding was revealed by the extracts of phytosupply Juglans regia L No. 2 (extractant - acetic acid to 5 %, nut of wax ripeness) and 4 (extractant, alcohol 20 % nutrient wax ripeness (proven after obtaining the primary extract of up to 5 % alcohol), which have bactericidal properties against gram-positive cocci and gram-negative sticks, but have a weak effect on the spore-forming bacilli. Key words: organic pig breeding, bactericidal activity, phyto-disinfectant, commonplace typical microflora of a pig complex, phyto row materials, walnut extract.

Conventional methods for assessing the quality of components mass produced using injection molding are expensive and time-consuming or involve imprecise statistical process control parameters. A suitable alternative would be to employ machine learning to classify the quality of parts by using quality indices and quality grading. In this study, we used a multilayer perceptron (MLP) neural network along with a few quality indices to accurately predict the quality of “qualified” and “unqualified” geometric shapes of a finished product. These quality indices, which exhibited a strong correlation with part quality, were extracted from pressure curves and input into the MLP model for learning and prediction. By filtering outliers from the input data and converting the measured quality into quality grades used as output data, we increased the prediction accuracy of the MLP model and classified the quality of finished parts into various quality levels. The MLP model may misjudge datapoints in the “to-be-confirmed” area, which is located between the “qualified” and “unqualified” areas. We classified the “to-be-confirmed” area, and only the quality of products in this area were evaluated further, which reduced the cost of quality control considerably. An integrated circuit tray was manufactured to experimentally demonstrate the feasibility of the proposed method.
