Authors: Shabanov Adam Emirsultanovich
Published: February 2022

The research was carried out in 2018-2020 on a new early potato variety Azart  in Russian Potato Research Centre in the conditions of sod-podzolic sandy loam soils of the Central region of the Non-Chernozem zone. In the experiment, we studied a complex of agrotechnical techniques, including the timing, density of planting and methods of applying mineral fertilizers in order to accelerate growth, subsequent development, increase plant productivity and uninterrupted supply of nutrients throughout the growing season. It was found  out that early planting accelerated the emergence of seedlings by 6-7 days, and the onset of the budding and flowering phase of plants by 4-6 days. The mass of the tops, and the area of the assimilation surface of the leaves increased by 1.5 t/ha and 2.6 thousand m2 / ha. The yield increase from early planting for an average of 3 years reached up to 1.8 t/ha or 4.5%, and from fractional fertilization up to 2.1 t/ha or 5.3% in comparison with the corresponding controls. The combined use of agricultural techniques in the experiment allowed us to obtain a yield increase of 3.7 t/ha or 9.7%.  Conditional income amounted to 39 thousand rubles/ha, and the cost price – 3.7 rubles/kg, which is 0.3 rubles/kg less than in the control. Thickening of plantings to 50 and 56 thousand tubers/ha contributed to an increase in the yield of tubers by an average of 2.8-3.3 t/ha or up to 8.7%, compared with the control. Conditional income increased on these options to an average of 8.0 thousand rubles/ha.

INFLUENCE OF CELLULOLYTIC ACTIVITY OF THE SOIL AND NUTRIENTS ON THE YIELD OF DURUM WHEAT IN THE STEPPE ZONE OF THE SOUTHERN URALS
Authors: Mitrofanov Dmitry Vladmirovich , Kaftan Yuri Vasilievich
Published: February 2022

The yield of durum wheat depends on many factors and the identification of the main ones is an important area of agrotechnological research. The cellulolytic activity of the soil and the content of macronutrients are one of these factors in the conditions of the southern chernozems of the steppe zone of the Southern Urals. Research on durum wheat is being conducted for the first time at the long-term stationary experimental site for crop rotations and permanent crops, established in 1988. In the experiment, such research methods as field, application, ionometric, and Machigina are used. Field experiments were conducted from 2002 to 2020 according to the method of B.A. Dospekhov. Positive results for nineteen years of research are observed in the second version of the experiment, which are manifested in an increase in the yield of durum wheat after black steam in a six-field crop rotation. The yield of wheat grain is 0.92 tons, feed units are 1.17 tons and energy units are 0.69 tons per 1 ha. The increase in yield depends on the cellulose-decomposing activity of microorganisms and the content of nutrients (NO3 -, P2O5, K2O) in the soil and the share of influence is 51.62, 52.43, 35.27 and 36.80 %. A decrease in the cellulolytic activity of the soil leads in the seventh variant of the experiment to the lowest yield and the yield of grain is 0.51 tons, feed, energy units-0.65; 0.38 t/ha. The formation of a low yield of durum wheat occurs despite the influence of nitrates, mobile phosphorus, and exchangeable potassium in the arable layer (0-30 cm) of the soil and the share is 45.45, 31.91, and 42.63 %. The level of the degree of decomposition of linen according to the experimental variants is in the range from 5.4 to 12.6 %. The range of nutrient content is nitrates from 5.1 to 8.0 mg, phosphorus-4.0-4.5 mg, potassium - 31.9-41.0 mg per 100 g of soil. The studied factors are the reason for the change in the yield of durum wheat.

Published: February 2022

Chlamydia is the main cause of diseases related to reproductive health, and iron plays an important role in the pathogenesis of chlamydia. Azithromycin preparations are widely used for the treatment of bacterial infections. One of them is "aZitronite. The drug "aZitronite" was administered 0.5 ml per animal, 1 time per day, for 7 days. In sick animals, the number of leukocytes in the blood increases by about 2 times compared to healthy animals (10.47 ± 0.32 ? 109 / l). After treatment, the number of leukocytes decreases by 17.9% relative to the indicator of sick animals, but remains higher by 65.9% relative to healthy ones. It was found that the level of eosinophils decreased by 6.6%, and the level of neutrophils decreased by 7.9% relative to the initial level. The concentration of hemoglobin in the blood of sick animals before and after treatment was 160.9± 2.12 g / l and 140.9± 1.57 g /l, respectively, which is higher by 30.0% and 12.4%, respectively, relative to the control. The drug "aZitronite" has a pronounced positive effect on the body of sick animals.

Published: February 2022

The aim of the study was to analyze the regularities of the influence of the diameter of the suction holes and the vacuum depth in the vacuum chamber of the precision seeding apparatus on the probability of the formation of group seed feeds. The study was of an experimental nature and was conducted with a specialized stand in laboratory conditions. The results showed that an increase in the diameter of the suction holes (at a constant value of the suction force) led to an increase in the frequency of formation of group seed feeds. Moreover, when the values of this factor varied from 4 to 5 mm (when sowing maize), practically no changes in the seed supply were observed. At the same time, a decrease in the diameter of the holes of the seeding disc to values less than 4 mm led to a sharp decrease in the likelihood of the formation of double feeds, and at d > 5 mm, the frequency of group feeds increased rapidly. This can be explained by two possible reasons: the error of the experiment, which led to a distortion of the result, or the regularity associated with the fact that in this interval (4...5 mm) the change in the parameter d is compensated by the variability of the main sizes of the sown seeds. In the first case, the dependence of the formation of the frequency of group feeds on the diameter of the suction holes is linear; in the second, it is cubic. The analysis of the obtained dependences shows that with a diameter of the suction holes of 1,0...2,9 mm, it is possible to ensure the operation of the vacuum seeding apparatus with a sufficiently high quality (practically without the formation of zero and group seed feeds) by excluding the reflector from the apparatus design. However, in this case, it is necessary to verify the reliability of each of the obtained dependences, since in the first case the required vacuum in the vacuum chamber is about 113 kPa, and in the second “only” 13.5 kPa.

Tra Milano e Parigi: Medardo Rosso e la vita moderna
Authors: Barzaghi Ilaria M.P.
Published: February 2022

Il valore di Medardo Rosso (1858-1928) scultore è riconosciuto, ma la sua ricerca della “verità”, sia nel senso di natura che di modernità, è stata rivoluzionaria attraverso ogni linguaggio artistico usato. Il suo lavoro pionieristico con la fotografia è un’efficace chiave di accesso alla vita e all’opera di questo artista, un elemento che ne dichiara con immediatezza la modernità, lo sperimentalismo e l’audacia. Da un lato, la fotografia è organicamente connessa alla sua scultura (non fotografava nient’altro) e costituisce uno strumento privilegiato per comprenderla, ma d’altra parte è un’arte del tutto indipendente. Sculture e fotografie sono legate dal comune linguaggio della luce: unite dalla ricerca di Rosso sul potere della luce di dare forma ai materiali. Seguendo il percorso di Rosso tra Milano e Parigi, emergono i caratteri fondamentali della sua modernità, anche nel senso che la sua indagine conduce alla produzione di quelle che Baudelaire ha chiamato “immagini della vita moderna”. Il saggio verte in particolare sulle serie di fotografie dedicate a Impressione d’omnibus, Enfant malade, La Conversazione, Bookmaker.
The importance of the Italian sculptor Medardo Rosso (1858-1928) is well recognized, but his search for truth, that is to say both nature and modernity, was revolutionary through every visual language he used. Still his pioneering work as an artist-photographer is little-known outside the academic community. His photography is deeply interconnected with his sculpture (he took pictures only of his own works) but at the same time it’s a fully independent art. Sculptures and photographs are linked together by the common language of light shaping both, that is to say by Rosso’s research about its power to shape different materials. Looking at his photographic production can be an effective way to comprehend Rosso’s life and art: it shows his modernity and experimentalism. Following his path from Milan to Paris, the essay focuses on some momentous photographic series, the images of Impressione d’omnibus, Enfant malade, La Conversazione, Bookmaker, to highlight the fundamental features of Rosso’s modernity, that it also to say he created what Baudelaire called “images of modern life”.
La consumatrice in rivolta. La politicizzazione del consumo e il ruolo della donna nel pensiero di Teresa Billington-Greig
Authors: Pizzirani Silvia
Published: February 2022

In Gran Bretagna, tra la fine del XIX e l’inizio del XX secolo, il consumo era un argomento sul quale si confrontavano vari movimenti femminili e pensatrici radicali. Teresa Billington-Greig, autrice prolifica e per un certo periodo anche attiva suffragetta, attribuì al consumo, ma soprattutto alle consumatrici, un ruolo politico centrale nella lotta contro il capitalismo. Nei suoi scritti analizzò soprattutto le cause dell’esclusione delle donne dalla sfera politica e le ragioni per cui la workers’ revolt non fosse, fino ad allora, avvenuta. Secondo l’autrice il “divorzio economico” tra produzione e consumo era un artificio creato dalla classe dominante per dividere consumatori e lavoratori, e ciò aveva contribuito all’esclusione delle donne, che erano fortemente connesse alla sfera del consumo, dalla lotta politica. Rivalutare il consumo come momento politico era quindi un modo per combattere il dominio del profiteer e per rivalutare il ruolo delle donne nella sfera politica, perché solo una piena emancipazione femminile avrebbe permesso di creare una società libera nel suo insieme.
Between the end of the Nineteenth and the beginning of the Twentieth Century, in Great Britain consumption was a relevant topic on which various women’s movements and radical thinkers spoke their mind. Teresa Billington-Greig, a prolific author and for a certain period also a fervent suffragette, gave to consumption and consumers a central political role in the struggle against capitalism. In her writings she mainly analyzed the causes of the exclusion of women from the political sphere and the reasons of the failure of the workers’ revolt. According to the author, the “economic divorce” between production and consumption was an artifice created by the ruling class, which resulted not only in the division of consumers and workers, but also in the exclusion of women, a category strongly connected to the sphere of consumption, from the political struggle. Re-evaluating consumption as a political moment was therefore a way to fight against the domination of the profiteer and to re-evaluate the role of women in the political sphere, because only women’s liberation would have allowed the creation of a free society.
Il quadro politico italiano di fronte alla crisi d’Ungheria del 1956
Authors: Guarino Giuseppe
Published: February 2022

Lo studio esplora quelle che furono le reazioni italiane di fronte alla crisi d’Ungheria del 1956, tenendo conto del contesto storico-politico dell’epoca. L’Italia – governata dal primo esecutivo guidato da Antonio Segni, appoggiato da Democrazia cristiana, Pli, Pri e Psdi – vedeva l’ingombrante presenza del maggiore partito comunista d’occidente che, insieme ad un partito socialista ancora fuori dall’arco costituzionale, rappresentava una forte minaccia. Per questo motivo, è importante esaminare nel dettaglio i cambiamenti che quella crisi riuscì ad apportare al sistema partitico italiano, esaminando le attività del governo sia in sede nazionale che internazionali, nonché le principali attività e prese di posizione da parte dei diversi partiti politici.
This essay explores Italian reactions during the days of the 1956 Hungarian crisis, taking into account the historical-political context. The Italian government was led by Antonio Segni and supported by the Christian Democratic Party, Liberal Party, Republican Party, and Democratic Socialist Party. In any case, the presence of the biggest Western Communist Party and of a Socialist Party still in opposition to the government parties was seen as a great threat. That is why it is important to examine in detail the changes that the Hungarian uprising brought to the Italian party system, examining the government actions (both national and international) and the main activities and stances of the different political parties.
