Methodological foundations of economic assessment of yield of agricultural crops
Authors: Parmacli D. M. 
Published: March 2020

The methodology for assessing levels of land productivity in terms of cost recovery is presented in theoretical and practical aspects. Based on the method for grading the yield of agricultural crops, methodological approaches have been proposed to substantiate the indicators of four productivity levels, which form four zones: unproﬁtable, moderate, rational and optimal yield. At the breakeven point, whereby revenue from sales and total production and sales costs are equal, the company does not incur losses, but does not receive proﬁt either. After overcoming the breakeven point, the enterprise begins to make a proﬁt with each subsequent unit of production. In the zone of moderate productivity, the company makes a proﬁt which allows simple reproduction. In the zone of rational productivity of land, the proﬁt of the enterprise provides for a partial upgrade of production, necessary in conditions of expanded reproduction. To conduct an extensive upgrade of the production base in conditions of expanded reproduction, the enterprise should reach the optimal level of yield. Formulas are given by which enterprises can forecast their proﬁt per unit of area as a multiple of ﬁxed costs. A number of examples for calculating different levels of crop yield based on a case study of a particular enterprise in 2018 are presented. The suggested method will allow researchers to substantiate economic evaluation of yield levels achieved for each type of crop cultivated at any given agricultural enterprise. This methodology will also provide specialists of agricultural enterprises, teachers and students of higher educational institutions with modern methodological tools for the economic assessment of yield levels for cultivated crops.

The indicators of productivity, survival rate and behavior of young bulls of Hereford breed were studied in a comparative aspect when they were raised in winter in the northern part of Kolpashevsky district of the Tomsk region. During the housing period, low average air temperatures were observed: from 20°С in October to –50°С in December – January and –49°С in February. Bulls of the control group were kept in a unit of the "three-wall" type during wintering, while bulls of the experimental group – in a lightweight unit. The increase in live weight of bulls of experimental group was 2.2 times higher than that in the control group, the slaughter weight was by 68.3 kg and the weight of internal fat was by 6.0 kg more than in the control. In the experimental group, the survival rate of bulls before slaughtering was 2 times higher than that in the control. In terms of live weight, experimental animals from the age of 15 months to slaughter exceeded the control group by 19%. Ethological studies showed that different types of housing units had a signiﬁcant impact on animal behavior. The feed intake of the bulls of the control group was shorter by 54 minutes, (15%) than that of the experimental group. Animals also spent 95 minutes (20.21%) less on chewing cud compared to the experimental bulls. When kept in a lightweight type of unit, bulls were in motion for a longer time, as a result of which they rested 45 minutes less, which contributed to the increase in the metabolic processes in the body. The animals of the experimental group spent 50 minutes longer on eating food in comparison with the bulls in the “three-wall” unit. The air temperature in a unit of the "three-wall" type was close to the ambient air temperature, wherein the bulls spent most of their time lying down. The proﬁtability of growing bulls in the experimental group exceeded the control indicator by 1.6 times. In the light-type premises, the housing conditions of bulls in the winter period at extremely low air temperatures were most favorable.

The study aimed to estimate the reference evapotranspiration of sugarcane using the Priestley-Taylor method, comparing with the standard Penman-Monteith-FAO 56 method in the region of the São Francisco Submiddle Valley in the period from 2013 to 2016. Images of the Landsat-8 satellite of the OLI and TIRS sensors acquired from the North American space Agency (NASA) and meteorological data from the Instituto Nacional de Pesquisas Espaciais (INPE) were used, along with the Sistema de Organização Nacional de Dados Ambientais (SONDA) and the Instituto Nacional de Pesquisas Espaciais (INMET). The instantaneous radiation balance, soil heat flow, latent heat flow, crop coefficient (Kc) and Priestley-Taylor coefficient were estimated to obtain the reference evapotranspiration, which ranged from 0.00 to 3.65 mm d-1. The validation proceeded through the correlation between method of crop coefficient applied for Priestley-Taylor and Penman-Monteith. The value of R² 0.75, Pearson coefficient (R) 0.88 (strong correlation) and the mean error found in 1.81 mm d-1 were considered satisfactory. The Priestley-Taylor method was able to estimate the reference evapotranspiration in sugarcane production areas in the region of the São Francisco Submiddle Valley in a satisfactory way.

A cultura do algodoeiro possui variações fenológicas importantes que influenciam no comportamento espectral e que podem auxiliar no dinâmico processo de manejo. O objetivo deste trabalho foi avaliar as aplicações das bandas multiespectrais do sensor Landsat-5TM, e a caracterização espectrotemporal da fenologia da cultura do algodoeiro sobre o cultivar 966 Bayer Fiber Max®. Foram calculados os índices de vegetação (IV) para auxiliar na descriminação da fenologia do algodoeiro. O monitoramento temporal revelou que o melhor IV para caracterização temporal foi EVI (0,939-maio/09-0,704 agosto/09) que apresentou resultados condizentes com as fases fenológicas da cultura. As transformações Tasseled Cap (Wetness, Greenness e Brightness) foram associados a parâmetros físicos da área de estudo e correlacionadas estatisticamente com os dados dos IV propostos, os índices NDWI, NDVI e SAVI com maiores valores de correlações com os componentes Wetness (r=0,869;p<0,05), Greenness (r=0,878;p<0,05), Brightness (r=0,761;p<0,05), respectivamente. Pela banda termal (B6) foi estimado a temperatura de superfície, validada por dados de laboratórios virtuais e pela estação meteorológica do INMET. Assim, foi possível identificar e relacionar as alterações na reflectância espectral do algodoeiro no espaço e no tempo, possibilitando interpretar os estágios vegetativos da cultura remotamente.

Na resolução de muitos problemas de engenharia é necessário melhorar as características do solo, de maneira a assegurar que seja capaz de suportar as cargas aplicadas sem deformação excessiva, mantendo a sua resistência e estabilidade, dessa forma é fundamental gerar informações técnicas para auxiliar os engenheiros na tomada de decisão. Realizado através do ensaio de Proctor, este trabalho tem como objetivo a determinação da relação entre o teor de umidade e a massa especifica aparente seca do latossolo, mediante estudo bibliográfico e ensaio laboratorial. Os procedimentos laboratoriais foram realizados obedecendo as normativas NBR-7182, que especifica o Ensaio de compactação, e a NBR-6457, que determina o método para preparação de amostras de solos. Esses permitem a obtenção do valor do peso específico seco, que com o aumento do teor de umidade atinge um valor máximo correspondente à umidade ótima, esta é localizada na ordenada máxima da curva de compactação. Sendo assim, para o ensaio realizado com o Latossolo Amarelo, foi verificado a massa especifica aparente seca máxima correspondendo a 3,02 g/cm³ e umidade ótima corresponde a 11,20%.Palavras-chave: Ensaio de Proctor, Latossolo Amarelo, Compactação.
Improvisatory Exercises as Analytical Tool
Authors: Bertolani Valentina 
Published: March 2020

Avant-garde improvised music tends to elude analytical attempts, which have so far mostly focused on transcribing and describing sound parameters (e.g., pitch, timbre, texture, etc.) in the extant recordings. However, this does not account for the irreducible immediacy of the improvisatory practice, whose recordings are just the tip of the iceberg of a more multifold and varied production (often not recorded). This issue, inherent to the type of creative process at hand, suggests that, when analyzing, we should also take into consideration what aesthetical principles influenced the choice of a succession of musical events over another.
The principles of action-reaction and of non-repetition of the musical material were the guiding elements of the improvisatory practice of the Italian Gruppo di Improvvisazione Nuova Consonanza (GINC) in the period 1965–1969. To adhere to these principles, GINC created a set of exercises to be practiced by members during the rehearsals. In this article I will analyze three examples from a 1967 video recording of the Gruppo di Improvvisazione Nuova Consonanza using these exercises to understand and comment the choices made on the spot by the improvisers. This strategy affords a better awareness of the group actions within the improvisatory context.
Revisiting the digital noise reduction in automatic contouring of “ice-water” objects
Authors: Zvyagin K. N. , Maltsev D. D. 
Published: March 2020

This work describes the practical implementation of the method for digital noise suppression during processing images containing ice information to recognize automatically the contours of «ice-water» objects during aerial photography. Images containing ice information have special characteristic structural features related to noise, e.g.granularity, glare, ice crumbs. This makes difficult or even impossible to recognize automatically the contours of ice-water objects. It is known that the success of the application of edge recognition methods depends on how much image noise is reduced. The paper discusses the construction method for the management of noise. The method is based on the sequential application of the Haar wavelet transform denoising using thresholding, clustering by k-means method. For the subsequent automatic construction of ice floes contours the Sobel operator is applied.The aim of the work is to develop a method capable to process digital images effectively that contain ice information with strong digital noise. In this work we treated the images of one-year ice containing strong digital image noise in the form of granularity and in the form of ice crumbs. A description of the features of each of the steps of the proposed method and practical application is given.As a result, the method was developed for processing images of ice information containing digital noise in absolute value commensurate with the basic data. It was noted that the use of the k-means method expands the scope. The k-rare method allows more detailed processing of ice information and distinguishes not only the contours of ice-water objects, but also the contours of ice crumbs.The conclusion formulates the main advantages of the method and the possible application of the algorithm in the process of local exploration of the ice conditions of the Northern Sea Route channel using unmanned aerial vehicle for aerial photography. The usage of unmanned aerial vehicle for aerial photography will increase the frequency of weather forecast updates and predict the appearance of ice objects at the ship’s heading. That will allow us to select the safest and most economical efficient route along the Northern Sea Route.The authors have no competing interests.
Analysis of the effects of auroral substorms on the data of ionosphere vertical sounding in the Arctic
Authors: Egorova L. V. 
Published: March 2020

The problem of diagnosing and predicting the characteristics of the polar ionosphere can be investigated by studying the effect of magnetospheric disturbances on the high-latitude ionosphere. Our task is to investigate the dependence of the variations in the electron concentration F of the ionosphere region at the subauroral stations of vertical sounding (VS) Sodankyla, Lovozero and Gorkovskaya on variations in the geomagnetic field. The data of AE and PC of geomagnetic indices were used during substorms in the winter of 2011–2012. For analysis, the epoch overlapping method was used. As a result, it was shown that the perturbation in the electromagnetic field is accompanied by a subsequent amplification of variations during the critical frequencies fоF2, and hence the electron concentration, auroral and subauroral ionosphere.We conclude that the geomagnetic indices AE and PC can serve as predictors of disturbances during the ionospheric parameter fоF2 of the high-latitude ionosphere in the winter season.An increase in the amplitude level of AE from 100 to 350 nT (and PC > 2) during the night hours of the winter season precedes an increase in the critical frequencies of the ionosphere F2 layer by an average of 30% of the median. An increase in the amplitude level of AE from 180 to 520 nT (and PC> 2) in the winter season in the afternoon precedes the positive or negative deviation of the critical frequencies of the ionosphere F2 layer from the median by a mean of 10%. The response of the high-latitude ionosphere of the F2 layer to variations in the AE and PC indices appears in the first hour after the maximum during geomagnetic indices, the delay of the maximum deviation from the median 1 hour at night and 3 hours in the afternoon at Lovozero station, at Sodankyla and Gorkovskaya is about 3 hours at night and weakly expressed during the day.I declare I have no competing interests.

The article presents the results of systematic measurements (2009−2017) of the total column abundances of methane (TC_CH4 ) and the column-averaged concentration (X_CH4 ) at the Antarctic station Novolazarevskaya. Solar radiation is recorded in the range 2990 – 3006 cm–1 using a diffraction spectrometer with 0.2 cm–1 resolution. The inverse task CH4 total column determining is achieved using the SFIT4 v0.9.4.4 code. The analysis shows that during the measurement period the average TC_CH4 was (3.4±0.8).1019 molecules/cm2 during the measurement period, and the average X_CH4 is (1663±34) ppbv. TC_CH4 trend is (4.5±2.2).1015 molecules/cm2 /month, and X_CH4 trend is (0.28 ± 0.11) ppbv/month. The average TC_CH4 values and trend at Novolazarevskaya are in good agreement with the measurements by the Brucker120HR instrument at the Arrival Heights station. Seasonal variations of atmospheric methane have the maximum in October–November and the minimum in May–July. The trends of surface methane concentrations at Sywa, the Halley station and the Amundsen-Scott South Pole station are 0.59 – 0.61 ppbv/month and exceed the trend of the column-averaged concentration at Novolazarevskaya and AIRS trends for the troposphere (0.24 – 0.32) ppbv/month, due to a decrease in the maximal values of TC_CH4 in the period after 2014. The closest agreement of X_CH4 variations at Novolazarevskaya with AIRS data is observed at the levels of 150–200 hPa. Significant semiannual harmonics varied with height are characteristic of CH4 variations according to the AIRS data. The interference of annual and semiannual harmonics leads to the appearance of two maxima in the seasonal variations of methane with relative position to each other varies with height. The statistical model is developed for all the series considered. It approximates the trend, annual and semi-annual components of CH4 oscillations.The authors have no competing interests.

Introduction. The urgency of the problem determines the high level of occupational morbidity in aluminum production workers and the prevalence of somatic pathology, which occupies one of the leading positions in the pathogenesis of fluorosis.The aim of the study is to determine the clinical and genetic features of the nature of concomitant visceral pathology in workers with industrial fluorosis.Materials and methods. A complex of clinical, biochemical, molecular, genetic, and instrumental research methods was used in patients with fluorosis (246 people) and in the control group (106 people).Results. A high frequency of health disorders in workers engaged in the production of aluminum was determined during long-term monitoring. An extended clinical and genetic study of the state of somatic organs in workers with fluorosis and in control is presented. It is revealed that in the group of subjects with proven diagnosis, pathologies concomitant with the main disease were significantly more common: pathologies of musculoskeletal and articular systems, blood circulation, respiratory (rhinitis, chronic, toxic and dust-borne bronchitis, chronic obstructive pulmonary disease), hepatobiliary (steatosis, fluoride hepatopathy), gastrointestinal tract (chronic gastritis, cholecystopancreatitis), renal systems (pyelonephritis, urolithiasis), as well as a combination of several nosologies was in 43%. The association of GG VEGF genotypes with chronic pyelonephritis and TT Il1ß, GSTT 1 0/0 with fluoride hepatosis was revealed in patients with fluorosis.Conclusions. The structure of occupational morbidity in workers of the main professions of aluminum production is dominated by concomitant pathology of functional systems against the background of bone destruction, determined by endogenous factors of the course of metabolic processes of the body.The authors declare no conflict of interests.
