The complex process of adaptation of modern society to the new conditions of development associated with the introduction of the latest achievements of scientific and technological progress has been examined. In this regard, the features of scientific and technological progress, its impact on the labor market, as well as the problems of technological backwardness of Russia have been analyzed. As an empirical base, the authors have used some results of the sociological study “Problems and prospects of the Russian labor market”, conducted by the author in Nizhny Novgorod in 2018 using the method of in-depth expert interviews. The study has identified 26 storylines, one of which, related directly to the views of experts on scientific and technological progress. The characteristic of this storyline has been presented in the article.

Em tempos em que parece aflorar toda forma de discriminação, seja relacionada à cor da pele, à orientação sexual, à identidade de gênero ou à procedência de determinados grupos sociais, o livro Preconceito contra a origem geográfica e de lugar: as fronteiras da discórdia, de Durval Muniz de Albuquerque Júnior, apresenta salutar discussão ao abordar a construção histórica dos diversos preconceitos geográficos no Brasil, principalmente em relação ao povo nordestino. Como o próprio autor define, preconceito de origem geográfica está relacionado ao pertencimento a certo território, espaço ou lugar considerado inferior, atrasado, subdesenvolvido, além de estar ligado a relações de poder que criam diferenças e desigualdades, quer nos campos econômico, político e militar, quer nos campos cultural, social e religioso.

This paper aims at analysing the celebration of the Portuguese language verified in the Brazilian issue number 479 of Vogue magazine, published in July 2018. The analysis adresses to the cover of the magazine as well to the text Portuguese in the vein, written by Nizan Guanaes and also published in the referred issue. Taking into account the conception of monolingual discourse, as designed by Zolin-Vesz and Santos (2017), it portrays the monolingual placement suggested by the cover and the text above mentioned in relation to the construction of an essentialized Portuguese language, a monolithic institution that contributes to the notion of homeland and has to be injected in the veins of Brazilian people as the inherent part of the axis national territory-language-identity-literature. Results suggest that the monolingual discourse conducts the celebration of the Portuguese language in the issue of Vogue magazine as well as contributes to harden the conception of (national) language.

ABSTRACT The upper Teles Pires River basin is located in the Brazilian agriculture frontier in the north of Mato Grosso state and has experienced significant changes in land use and cover, which can cause major changes in its hydrological dynamics. Climatic and hydrologic data are scarce in the region, which poses uncertainties in the decision-making process aiming at the sustainable management of water resources in this strategic area. The aim of this study was to evaluate the performance of the Large-Scale Distributed Hydrological Model (MGB-IPH) to assess water availability of the upper Teles Pires basin and support water resource management in the Amazon-Cerrado ecotone. The MGB-IPH model was calibrated and validated using data from three streamflow stations available in the basin. In order to verify the model performance, the Nash-Sutcliffe (NS) and the PBIAS statistical parameters were applied. Our results show that, by using the MGB-IPH model with generally available data, the maximum and minimum flow regimes can be successfully assessed in the upper Teles Pires basin. The continuity curves of daily flow simulated by the model showed a good fit with the observed flow. Overall, the results demonstrated the applicability of the MGB-IPH model for water resource assessment and management in the basin.

BackgroundRespiratory failure after acute spinal cord injury (SCI) is well recognized, but data defining which patients need long-term ventilator support and criteria for weaning and extubation are lacking. We hypothesized that many patients with SCI, even those with cervical SCI, can be successfully managed without long-term mechanical ventilation and its associated morbidity.MethodsUnder the auspices of the Western Trauma Association Multi-Center Trials Group, a retrospective study of patients with SCI at 14 major trauma centers was conducted. Comprehensive injury, demographic, and outcome data on patients with acute SCI were compiled. The primary outcome variable was the need for mechanical ventilation at discharge. Secondary outcomes included the use of tracheostomy and development of acute lung injury and ventilator-associated pneumonia.ResultsA total of 360 patients had SCI requiring mechanical ventilation. Sixteen patients were excluded for death within the first 2 days of hospitalization. Of the 344 patients included, 222 (64.5%) had cervical SCI. Notably, 62.6% of the patients with cervical SCI were ventilator free by discharge. One hundred forty-nine patients (43.3%) underwent tracheostomy, and 53.7% of them were successfully weaned from the ventilator, compared with an 85.6% success rate among those with no tracheostomy (p < 0.05). Patients who underwent tracheostomy had significantly higher rates of ventilator-associated pneumonia (61.1% vs. 20.5%, p < 0.05) and acute lung injury (12.8% vs. 3.6%, p < 0.05) and fewer ventilator-free days (1 vs. 24 p < 0.05). When controlled for injury severity, thoracic injury, and respiratory comorbidities, tracheostomy after cervical SCI was an independent predictor of ventilator dependence with an associated 14-fold higher likelihood of prolonged mechanical ventilation (odds ratio, 14.1; 95% confidence interval, 2.78-71.67; p < 0.05).ConclusionWhile many patients with SCI require short-term mechanical ventilation, the majority can be successfully weaned before discharge. In patients with SCI, tracheostomy is associated with major morbidity, and its use, especially among patients with cervical SCI, deserves further study.Level of evidencePrognostic study, level III.

Objective. Determination of the effectiveness of final disinfection treatment of virological laboratory rooms (with the passageway room between two entries) in the isolated zone used for work with pathogenic agents, of the maximum containment laboratory by fumigation with formaldehyde vapors, including the assessment of the optimal amount of formalin. Experimental evaluation of the suitability of the aerosol generator “Ultrasprayer P-60” for the final disinfection of the premises of the “contagious” zone with the “dry steam” of hydrogen peroxide. Materials and methods. The effectiveness of the final disinfection of the surfaces in the premises of the “infectious” zone of the maximum containment laboratory was evaluated using cambric test objects contaminated by the spore-forming test-culture B. thuringiensis. Results and discussion. As a result of experimental studies, the required amount of formalin was determined that is sufficient to completely inactivate possible infectious contaminants that may be potentially located on the surfaces of equipment and rooms located in the “contagious” zone of the maximum containment laboratory, during fumigation with formaldehyde vapors. The amount of formalin specified experimentally turned out to be 1.4 times more than the recommended by regulatory documentation for unventilated rooms, but 2-2.5 times less than that used for final disinfection of maximum containment laboratory previously. Disinfection treatment of the premises and equipment located in the “contagious” zone of the laboratory with 6 % hydrogen peroxide “dry steam”, which is the active agent of Disargent drug, sprayed through the «Ultrasprayer р-60» aerosol generator, was more effective than spray irrigation with 6 % hydrogen peroxide aerosol generated using pneumatic aerosol nozzles. At the same time, it was possible to achieve sufficiently complete inactivation of the test microorganism located on test objects at a concentration of 1·106 cells/cm2, by increasing the concentration of hydrogen peroxide sprayed by the device up to 10 %. However, even in that case, viable test microorganisms remained in the hidden cavities of the equipment and office machinery, which makes further studies relevant to establish the optimal concentration of hydrogen peroxide during the final disinfection with an «Ultrasprayer р-60» aerosol generator or similar equipment from other manufacturers.

Trata-se de uma leitura de A república dos sonhos, de Nélida Piñon, alicerçada na teoria crítica feminista, por meio da qual pretendo evidenciar o modo de representação de personagens femininas que compõem o romance, atrelado à perspectiva sociocultural da escritora e ao pensamento feminista. Nessas reflexões, saliento que o processo de subjetificação galgado pelo conjunto das mulheres da obra, e sintetizado na figura de Breta, passa pela conquista do direito de narrar/falar, nos termos de Gayatri Spivak (2010) e de Homi Bhabha (2014). A ancestral subalternidade feminina, nesse sentido, é superada à medida que a narradora-protagonista vai se constituindo como sujeito, no movimento mesmo em que se investe da capacidade enunciativa e toma a palavra.

El objetivo general de este artículo es problematizar, desde las novelas cortas Entre rinhas de cachorros e porcos abatidos (2009) y O trabalho sujo dos outros (2009), así como las novelas Carvão Animal (2011), De gados e homens (2013) y Assim na terra como embaixo da terra, de Ana Paula Maia, el modo como su escritura literaria reverbera en el campo literario de autoría femenina, y promueve subversiones ideológicas y estéticas en la órbita de las producciones literarias contemporáneas. El aporte teórico es constituido por los conceptos de biopolítica, de Giorgio Agamben; la tríada de lo Imaginario, lo Simbólico y lo Real, de Slavoj Žižek, y el referente ausente, de Carol Adams.

In environmental conditions, plants can be affected by the action of numerous abiotic stressors. These stressors can induce both damage of physiological processes and adaptive changes including signaling-based changes. Development of optical methods of revealing influence of stressors on plants is an important task for plant investigations. The photochemical reflectance index (PRI) based on plant reflectance at 531 nm (measuring wavelength) and 570 nm (reference wavelength) can be effective tool of revealing plant stress changes (mainly, photosynthetic changes); however, its efficiency is strongly varied at different conditions. Earlier, we proposed series of modified PRIs with moderate shifts of the measuring wavelength and showed that these indices can be effective for revealing photosynthetic changes under fluctuations in light intensity. The current work was devoted to the analysis of sensitivity of these modified PRIs to action of drought and short-term heat stress. Investigation of spatially-fixed leaves of pea plants showed that the modified PRI with the shorter measuring wavelength (515 nm) was increased under response of drought and heat; by contrast, the modified PRI with the longer wavelength (555 nm) was decreased under response to these stressors. Changes of investigated indices could be related to parameters of photosynthetic light reactions; however, these relations were stronger for the modified PRI with the 555 nm measuring wavelength. Investigation of canopy of pea (vegetation room) and wheat (vegetation room and open-ground) supported these results. Thus, moderate changes in the measuring wavelengths of PRI can strongly modify the efficiency of their use for the estimation of plant physiological changes (mainly photosynthetic changes) under action of stressors. It is probable that the modified PRI with the 555 nm measuring wavelength (or similar indices) can be an effective tool for revealing photosynthetic changes induced by stressors.

A obra escrita por Paulo Gabriel Hilu da Rocha Pinto – Islã: Religião e Civilização: uma abordagem antropológica – exprime as ideias fulcrais sobre essa religião e suas subdivisões doutrinárias. Por meio da sua pesquisa etnográfica realizada desde 1999, Pinto objetiva entender as práticas, as subjetividades e os discursos daqueles que se identificam como mulçumanos, elusivando de explanações dogmáticas. Lamentavelmente, o campo produtivo-literário brasileiro tem sido alheio ao acompanhamento de pesquisas desenvolvidas no próprio país. Destarte, este livro oportuniza um maior entendimento sobre a pluralidade do Islã, sobre o Livro Sagrado (Alcorão) que é suscetível a análises diversas de cada indivíduo.

The use of mobile shelters to raise calves has been a practical alternative to farmers, taking into account their importance in reducing the spread of diseases as well as thermal stress. Despite the fact that individual shelters are widely employed in the country, there is little information on the thermal efficiency of materials that are normally used to build them (Barnabé et al, 2014), as well as the high cost involved in their construction. The aim of this study was to evaluate the following variables: temperature, relative humidity and temperature-humidity index (THI), and the cost-benefit ratio of the recyclable materials used to cover the shelters. Bottle PET (T2), tires (T3), milk packaging (Tetrapack™) (T4) and one sensor as baseline left in full sun. During a 40 days period, the temperature and relative humidity data were recorded hourly, to obtain daily averages. There was no statistical difference (p> 0.05) between materials related to temperature, relative humidity and ITU averages. Even the critical temperature and humidity do not presented significant variation between the treatments (p> 0.05). Considering the results, there is no significant differences among the materials used related to the thermal efficiency based on the above mentioned variables . Therefore, it can be concluded that thereplacement of the conventional roof (Eternit®) by these alternative materials becomes feasible, based on the lower costs and the ecological appeal for recycle materials.

This paper aims at suggesting possibilities to consider Me llamo Rigoberta Menchú y así me nació la conciencia, which was published in 1985, as an opportunity to a non canonical literature teaching in high school. In accordance with Grosfoguel’s proposition (2008) to move the positioning from the European man to American indigenous women, such as Rigoberta Menchú, and seeking to embrace those literatures that are still hardly studied in high school, it is suggested to build perspectives to discuss social life aspects, in particular those exclusion and social injustice situations that are perpetuated by the process of coloniality.

The netted melon requires special growing conditions, including a protected environment, an adequate staking system and proper water and nutrient management. This study aimed to assess the effect of irrigation levels and silicon doses on the yield and quality of Sunrise hybrid melons, in a greenhouse. A randomized block design was used, with a 5 x 3 factorial scheme and four replications. The first factor consisted of five silicon doses (0 kg ha-1, 50 kg ha-1, 100 kg ha-1, 150 kg ha-1 and 200 kg ha-1) and the second of three irrigation levels (40 %, 70 % and 100 % of the ETc). The results demonstrated that the applied irrigation levels and silicon doses have no influence on the yield traits of melon plants. The irrigation level corresponding to 100 % of the ETc promotes higher values for soluble solids (9.86 ºBrix) and maturation index (114.9) on fruits. The increase of silicon doses up to 200 kg ha-1 also increases the maturation index in the treatment with the greatest irrigation level and reduces this index at the shallowest level applied.

ABSTRACT The upper Teles Pires River basin is a key hydrological resource for the state of Mato Grosso, but has suffered rapid land use and cover change. The basin includes areas of Cerrado biome, as well as transitional areas between the Amazon and Cerrado vegetation types, with intensive large-scale agriculture widely-spread throughout the region. The objective of this study was to explore the spatial and temporal dynamics of land use and cover change from 1986 to 2014 in the upper Teles Pires basin using remote sensing and GIS techniques. TM (Thematic Mapper) and TIRS (Thermal Infrared Sensor) sensor images aboard the Landsat 5 and Landsat 8, respectively, were employed for supervised classification using the “Classification Workflow” in ENVI 5.0. To evaluate classification accuracy, an error matrix was generated, and the Kappa, overall accuracy, errors of omission and commission, user accuracy and producer accuracy indexes calculated. The classes showing greatest variation across the study period were “Agriculture” and “Rainforest”. Results indicated that deforested areas are often replaced by pasture and then by agriculture, while direct conversion of forest to agriculture occured less frequently. The indices with satisfactory accuracy levels included the Kappa and Global indices, which showed accuracy levels above 80% for all study years. In addition, the producer and user accuracy indices ranged from 59-100% and 68-100%, while the errors of omission and commission ranged from 0-32% and 0-40.6%, respectively.

Bell pepper is a vegetable-fruit of great economic importance in Brazil. Crop production demands adequate water supply, nutrients, and light. The objective of this study was to evaluate gas exchange (net photosynthesis, stomatal conductance, transpiration, internal carbon concentration and instantaneous carboxylation efficiency) and dry mass accumulation in leaves and roots under fertigation with nitrogen and potassium. The experiment was conducted in a completely randomized design in a factorial scheme (4 × 4) with four replications and a total of 64 experimental units. Treatments consisted of a combination of four nitrogen doses (0; 73.4; 146.8 and 293.6 kg ha-1 of N) with four doses of potassium (0; 53.3; 106.7 and 213.4 kg ha-1 of K). An infrared gas analyzer (IRGA) coupled with a light source (irradiation of 600 µmol m-2 s-1) was used for the evaluation of gas exchange. There was a significant interactive effect of N and K on net photosynthesis and leaf and root dry mass. Root dry mass was the variable that best expressed this interaction. Physiological variables measured were more responsive to nitrogen fertilization than to K fertilization. The optimum values of stomatal conductance, transpiration, internal carbon concentration and carboxylation efficiency were obtained with the application of nitrogen doses between 147 and 294 kg ha-1.

Fertilization is important for the optimization of plant growth and yield, which are necessary for agronomic activities. Soil fertilization should increase net earnings that depend on nutrient use efficiency. The aim of this study was to evaluate the agronomic efficiency of eggplant under different doses of potassium (K) and nitrogen (N). Four levels of K (0, 54, 108, and 216 kg ha-1) and four levels of N (0, 67, 134, and 268 kg ha-1) were applied weekly by fertigation. The highest plant and the largest stem diameter were found with 165-175 kg ha-1 of N. Leaf area was more influenced by N than by K. Isolated application of different K doses did not statistically influence height plant, stem diameter, or leaf dry matter. The agronomic efficiency of nitrogen is reduced with increasing levels of N and K.
