El objetivo de este trabajo fue cuantificar el número y duración de los esfuerzos de muy alta intensidad y esprint (EMAVS) y el intervalo de recuperación entre ellos en 36 futbolistas profesionales de primera y de segunda división. Los jugadores fueron monitorizados a través de dispositivos GPS durante dos partidos oficiales.

La duración promedio de los EMAVS fue de 2,58±0,44 segundos con un intervalo medio entre los mismos de 107,07±67,00 sg. La FC media durante los EMAVS se situó en 164,92±12,39 p.p.m., alcanzando el 85% de la FC máxima. No se encontraron diferencias significativas entre la duración de los EMAVS, los intervalos entre ellos y la FC alcanzada (p? 0,05 en todos los casos), con gran variabilidad individual.

La utilización de la duración de los EMAVS, los tiempos de recuperación y la FC alcanzada durante los mismos, serían de gran utilidad para diseñar los entrenamientos interválicos en el fútbol.
Corrosion of titanium implants and connected prosthetic alloys using lactic acid immersion test
Authors: Niedermeier Wilhelm , Huesker Katrin
Published: March 2021

Background/purpose: Combination of dental titanium implants with other prosthetic metallic components may lead to metal ion release that increases the risk of adverse reactions in patients. The present study therefore aimed to determine in vitro metal ion dissolution from different alloy combinations. Materials and methods: Dental alloys were subjected to a lactic acid immersion test together with titanium implants and matched with controls. Between day 1 and 38, open direct current potentials (DCP) between the samples and the electrolyte were recorded and metal dissociation inside the electrolyte was assessed using ICP-MS. Results: Absolute DCPs of the different alloys increased significantly (p<0.001) from 100-150mV to 490-580 mV within the first two weeks of immersion, dropping to about 450mV later on largely independent of the material. Titanium showed highest dissociation rates (2.00-12.06µg/cm2 per day; p=0.0002); all other components demonstrated poor corrosive dissolution (<0.6µg/cm2 per day). After immersion of 38 days, titanium still yielded high dissociation (0.64-1.38µg/cm2 per day) for all test groups. Presence of fine gold inside the electrolyte significantly increased dissociation of titanium (p=0.027). Dissociation of iron indicated contamination from tool components used for implant production. Optical examination of non-precious metal surfaces showed no corrosive discoloration after 5 or 26 weeks of lactic acid immersion. Conclusion: Within the limitations of this study, there is no objection against the use of non-precious alloys for the fabrication of components and prostheses supported on titanium implants if gold is not present inside the same electrolyte.
Structural and financial risks of land capitalization: lessons of domestic history

The article is devoted to the problem of the relationship between expected results and real institutional, structural, and financial consequences of agrarian reforms aimed at the capitalization of land. The purpose of the publication is to summarize the positive and negative experience of the peasant reform of 1861 on changes in the relations of ownership and land use in the budgetary and financial sphere and foreign economic activity. Research is based on the history-institutional methodology using tools of economic comparability, retrospective analysis, and historical reconstruction. It is defined that the opening of the land market and the creation of a system of mortgage land loans allowed to increase the share of private land ownership of peasants, but did not turn them into effective owners and did not solve the problem of peasant land. Rising land prices contributed to the development of land speculation and increased rents, encouraging the farmers to predatory land use and depletion of soils without increasing productivity. The capitalization of land and the expansion of the hired labor market contributed to economic growth, increased government revenues and expenditures, and overcame the chronic state budget deficit. At the same time, the credit indebtedness of peasants grew, while ransom payments depleted peasant farms, reducing the potential for capital formation and investment. The public policy of forcing grain exports and supporting large agribusiness allowed to replenish the gold reserves of the treasury, but also led to the impoverishment of farmers, reduced quality of the exported grain, increased share of fodder crops, and lower share of food crops and finished goods. Intensified international competition to expand the supply of cheap grain led to lower prices, weaker competitive position of domestic exporters, and the growing dependence of the economy on world markets for agricultural products, and the local agrarian business - on foreign capital. The article provides recommendations to the government about taking into account the historical experience in the implementation of modern agrarian transformations, in particular, comprehensive support for farming as the main link of agricultural production and the guarantor of food security of the country. Their implementation will help prevent the risks of over-concentration of land, the proletarianization of the peasantry and its mass migration to cities and abroad, growing environmental problems, and vulnerability of the economy due to increasing dependence on the world markets for agricultural raw materials.
Physics of geospace storms
Authors:   V.N. Karazin National University of Kharkiv, Kharkiv, Ukraine, Chernogor L.F.
Published: March 2021

A review of our knowledge about the coupling of solar-terrestrial processes, manifestations of geospace storms, and variations in space weather is presented. Space weather effects are analyzed within the system paradigm concept. The system where geospace storms occur is a Sun–interplanetary medium–magnetosphere–ionosphere–atmosphere–Earth (interior spheres) aggregate (SIMMIAE). An early twenty-first- century geospace superstorm that occurred on November 7 – 10, 2004, is examined in detail. Clustered instrument observations of this storm effects are presented. The investigation of the physical effects of geospace storms is noted to be the most important field of study in space geophysics. The problem of subsystem coupling in the SIMMIAE system during a geospace storm is interdisciplinary in nature. Its solution requires an application of the system approach. The problem has a multifactor character. The subsystem response is determined by the simultaneous (synergetic) impact of a few disturbing factors. It is important to note that the SIMMIAE is an open, nonlinear, and nonstationary system. Within it, direct coupling and feedback processes, positive and negative linkages operate. Due to the myriads of manifestations of geospace storms, because of the unique nature of each storm, the investigation of occurring physical effects is far from complete. In addition to a thorough investigation of the storm’s physical effects, there is an urgent need to model and forecast the storms adequately and in detail. The solution to these problems will facilitate the survival and steady progress of our civilization, relying more and more on new state-of-the-art technology. The more technologically reliant our society is, the more vulnerable the civilization's infrastructure to solar and geospace storm impacts becomes. A classification of geostorms based on Akasofu's epsilon parameter has been advanced. Six types of geostorm have been introduced, and a geostorm index has been suggested. A classification of ionospheric storms and disturbances based on the magnitude of variations in the peak density of the F2 layer has been suggested. Five types of the ionospheric storm have been introduced. An ionospheric index characterizing the intensity of negative and positive ionospheric storms has been suggested. A classification of ionospheric storms and disturbances based on the magnitude of variations in the lower-ionosphere electron density has been proposed. Six types of the positive ionospheric storm have been introduced. The appropriate ionospheric index has been suggested. The physics-based model of the evolution of each group of ionospheric storms and disturbances has been determined. The linkages among magnetic, ionospheric, and atmospheric storms, as well as electric field disturbances, have been shown.

There is an increasing trend to liquid-propellant rocket engines which run on eco-friendly storable propellant. This trend is mostly dictated by the refusal to use traditional toxic storable propellant in many countries. The most widespread eco-friendly storable propellant is hydrogen peroxide with kerosene. Though, this propellant has a lower specific impulse in comparison with traditional liquid oxygen with kerosene. To compensate the loss of specific impulse, there is a reason to design a staged combustion engine. Evidently, the turbopump is the most complicated system in the staged combustion propulsion system. This fact makes research devoted to turbo-pumps a top priority. The paper aims to determine the influence of propellant leakage from the pump area into the turbine area and create recommendations which would allow organizing the stable operation of turbopump. As a result of turbopump staged combustion cycle testing, a conclusion had been made that leakage, which opens during the test, significantly influences the stability of turbopump operation. Depending on the amount of leakage, the turbine generated power drop was between 20 and 45%, which led to a decrease in rotation speed and outlet pressure of the pump. During the R&D process, a way of leakage influence elimination had been offered. Formulated recommendations may be used during the design process of the turbopump for staged combustion liquid propulsion systems.
Static Buckling of a Pre-loaded Complex Nano-composite Shell

This paper describes a technique for analyzing the phenomenon of static buckling of a pre-loaded complex nano-composite shell. Most of the works devoted to the analysis of complex structures consider vibration processes, while the phenomenon of buckling can be an important factor that limits the use of new materials in space-rocket hardware. A nano-composite constant-thickness shell consisting of two spherical covers and a cylindrical body is considered. It is acted upon by internal pressure and an axial compressive force. This shell simulates the fuel tank of a launch vehicle. Conditions under which the shell is deformed non-axisymmetrically, buckling statically, are investigated. A technique is proposed that allows the problem to be divided into the analysis of the pre-loaded state of the shell and the analysis of buckling. Further analysis is performed using a technique based on the high-order shear deformation theory and the Ritz method. The problem is discretized by representing the variables that determine the state of the shell in the form of expansions in basis functions with unknown coefficients. Thus, it is the expansion coefficients that become unknown in the problem. The problem of analyzing the pre-stressed state of a structure is reduced to solving a system of linear algebraic equations with respect to the expansion coefficients. The problem of buckling analysis can be reduced to the problem of eigenvalues. The solution to this problem makes it possible to find the minimum value of the compressive load at which the shell buckles, as well as the forms of buckling. The results of applying the developed technique were compared with those of finite element modeling of a structure made of the simplest nano-composite material. The comparison results indicate a high accuracy of the technique described. At the same time, the use of the finite element method for the analysis of large-scale thin-walled structures made of functionally gradient materials is extremely difficult, in contrast to the methodology proposed in the paper. Comparison of various types of nano-reinforcement showed that a rational choice of the type of reinforcement can significantly increase the critical load. In this case, the internal pressure on the shell also significantly affects the critical load.

L’article retrace les débuts de la carrière d’Aurélien Sauvageot, « l’homme de France qui connaît le mieux hommes et choses de Hongrie ». Elève d’Antoine Meillet, ﬁgure-clé des relations culturelles franco-hongroises de l’entre-deux-guerres, premier titulaire, en 1931, de la Chaire des langues ﬁnno-ougriennes à l’Ecole des langues orientales à Paris, Sauvageot fait son entrée sur la scène scientiﬁque, littéraire et politique française et hongroise à la sortie de la première guerre mondiale dans laquelle la Hongrie et la France étaient dans les camps opposés. L’arrivée de Sauvageot à Budapest (en 1923) et ses débuts dans le milieu de la linguistique ﬁnno-ougrienne permettaient de croire, pour la science et la politique françaises, que ce jeune linguiste bientôt hungarophone serait capable de servir la propagande intellectuelle, c’est-à-dire « la cause » française en Hongrie. Dans le sens inverse, aux yeux des autorités hongroises, on espérait qu’il pût disséminer la propagande intellectuelle hongroise en France. Or les objectifs communs (le rapprochement intellectuel) ne pouvaient compenser les contradictoires entre les deux pays, ces dernière se sont constamment imposées sur le chemin d’Aurélien Sauvageot.
“WHAT FOREIGN FASHION MAGAZINES ARE NOT ABLE TO GIVE” THE POLITICALLY MOTIVATED LANGUAGE OF FASHION IN THE MAGAZINE NŐVILÁG IN 1859–1860
Authors: KERPICS JUDIT
Published: March 2021

In the turn of the 1850’s and 1860’s a topic – which generated serious disputes in the reform era – flamed again in Hungary: it was the national clothing. With the slackening political rigour, the traditional Hungarian dress as a symbol of national togetherness was on the agenda yet again in Hungarian-language fashion magazines of Pest.

The Nővilág [Woman’s World] edited by János Vajda aimed to work on women’s aesthetical education since the start of the magazine in 1857. The column named Original Fashion Report was written by the leader contributor of the magazine Júlia Jósika, who has been corresponded up to date French and Belgian fashion from Brussels. Popularity of her articles was unbroken until 1860. The Original Fashion Report in this name was published for the last time in the february of 1860; then the column was renamed, and of results of a slow process until the end of the year Júlia Jósika’s fashion reports frayed from the Nővilág. Her place was taken by a young writer with increasing publicity, Lenke Bajza, who made a stand for national fashion. She – likewise Júlia Jósika – worked for the magazine as ﬁctionist and fashion professional.

This change can be associated not with aesthetical but political decisions. Because of a delicate international political situation in the year 1859 Hungarian revisionists started to hope again in a new revolution for independence from Austria. With a press being stricktly supervised by the police, traditional Hungarian fashion became part of the language of national solidarity.

In my paper I will confer the competition of French fashion and traditional Hungarian clothing through Júlia Jósika’s and Lenke Bajza’s confronting fashion reports and the alteration of Nővilág in the context of the politically charged alternative language of clothing.

400 YEARS AFTER THE BATTLE OF HUMENNÉ A POLISH SOURCE ON THE SIEGE OF VIENNA AND ITS AFTERMATH (1619-21)
Authors: SZTYBER RADOSŁAW
Published: March 2021

The article is an attempt to present The exploits of Polish elears, who were formerly called Lisovchiks (Przewagi elearów polskich, co ich niegdy lisowczykami zwano) by Wojciech Dembołęcki. The book’s form varies between that of a chronicle, a memoir, and a detailed diary. Nevertheless, the report contains an abundance of valuable and interesting data on the Battle of Humenné and its immediate consequences, particularly the paciﬁcation actions led by Polish mercenary troops. Dembołęcki’s Exploits can be thought of as, for many reasons, a unique source of knowledge on several historical episodes of the initial stage of the Thirty Years’ War. Its convention, however, is to show the Lisovchiks as an army of God, and therefore the publication (printed in Poznań in 1623) is also evidence of propaganda-motivated gloriﬁcation of the notorious elears who supported Ferdinand II’s forces twice (in 1619-21 and in 1622). Despite the exaggerated written praise, these soldiers were soon outlawed (in 1623) because of their conduct, especially during peaceful periods. The diary gives the reader a chance to get acquainted with authentic documents, such as correspondence addressed to Poles and signed by imperial authorities. The article mainly recalls selected facts (war tactics speciﬁcity, battles, marches, negotiations, etc.) in the chronological order on the basis of the account, but some examples of Dembołęcki’s comments are also cited, paraphrased, or discussed to give a better idea of the nature of the original memoir. In the concluding part of the study there are some remarks on Dembołęcki’s other work, enriched with a short description of a Latin manuscript (preserved in Prague) and a pair of booklets, the ﬁrst of which was issued in Vienna and the second somewhat later in Poland (the precise place of publication is unknown).

Authors: Özdemir F. , Arslan S. , Eken C. B.
Published: March 2021

A total of 46 Staphylococcus aureus isolates from fish and ground beef were tested for the agr types, icaABCD genes, and biofilm formation at 12, 25 and 37 °C by the microtiter plate and the MTT assays. All isolates were positive for the icaABD genes, while 97.8% were positive for the icaC. All isolates produced biofilms at 37 and 25 °C, but 93.5% of them were also biofilm producers at 12 °C. There was no significant difference in biofilm formation between 25 and 37 °C using the crystal violet assay (P > 0.05). However, statistically significant differences were detected between 12 and 25 °C as well as 12 and 37 °C (P < 0.05). All isolates were significantly different in biofilm production by the MTT assay at all tested temperatures. Furthermore, a relationship between the presence of the icaABCD genes and biofilm formation was observed. The agr type I was the most prevalent (54.4%) among the isolates, followed by agr type II (41.3%) and agr type III (9.6%). In this study, the S. aureus isolates exhibited biofilm formation ability responsible for persistence of bacteria in foods, which may lead to food spoilage and human health problems.

The article highlights new data on the effect of thyroid dysfunction on the formation of secondary amenorrhea in adolescent girls who live for a long time in conditions of weak iodine deficiency. The objective: to determine the state of the thyroid system in girls with SA, taking into account the presence of thyroid disorders. Materials and methods. Under observation were 68 girls aged 14-17 years with SA, living in conditions of weak iodine deficiency in Kharkov and the Kharkov region. The examination provided for an ultrasound of the thyroid gland and determination of the functional state of the pituitary-thyroid system. Girls with SA entered the main group. Depending on the presence of thyreopathy, namely, diffuse non-toxic goiter (DNG), the patients of the main group were divided into two subgroups: 1-st subgroup consists of a girls with SA and normal thyroid volume (n=39); 2-nd subgroup consists of girls with SA and DNG (n=29). The control group included 78 female peers with normal thyroid volume, harmonious physical development and normal menstrual function. Results. The obtained results allowed to establish that the formation of SA in girls living in conditions of low iodine deficiency occurs against a background of thyroid dysfunction, the character of which differs in girls with normal thyroid gland volume and DNG. This can be regarded as a succession of stages of the pathological process when, in conditions of prolonged residence in regions with a mild iodine deficiency, a distearosis is formed which is characterized by an increase in the fT4 conversion in fT3, reflecting an increase in the fT3/fT4 ratio in the vast majority of the girls surveyed. These changes in the thyroid profile negatively affect the development of the reproductive system and can cause menstrual dysfunction even in the absence of thyroid disease. The conclusion. Prevention and treatment of SA in girls living in conditions of low iodine deficiency, provides long-term use of pharmacological drugs potassium iodide in age doses. Key words: girls, thyroid gland, thyroid status, secondary amenorrhea.

Comparative Analysis of Fiscal Regulation Measures of the G20 Countries in the Era of the Coronavirus Crisis and in the Post-Coronavirus Perspective
Authors:   St. Petersburg State University, Pogorletskiy A. I. , Pokrovskaia N. V. ,   St. Petersburg State University
Published: March 2021

The article seeks to describe the features of fiscal policy during the Covid-19 pandemic. The research subject is the developed and developing countries of the G20 Group. The purpose of the article is to show an increasing importance of fiscal regulation measures in the era of the coronavirus crisis and in the post-coronavirus future, while noting the special role of taxation, which in modern conditions is given an important role in the toolkit for replenishing the revenue of state budgets of the leading countries of the world. The hypothesis of the research is that fiscal policy in the modern world acquires a qualitatively different meaning, becoming a priority of state regulation in the field of public finance, shifting the emphasis from the previous priority of monetary policy measures. Based on the generalization of the Covid-19 consequences on the economy and public finances and the experience of overcoming crises, the key postulates of modern fiscal policy were substantiated: clear socially oriented focus; focus on neutralizing excess income of companies that managed to take advantage of their technological advantages during the pandemic; a combination of support for the population by growing government spending and the use of tougher tax pressure on those who managed to get rich during the coronavirus crisis; consistency of the national fiscal policy of the post-Covid recovery period with the policies of other countries of the world. Summarizing the experience of implementing fiscal policy in China, Japan and Korea since the early 2020s made it possible to highlight the differences between countries in the tax response to the pandemic, as well as to the recovery after it: the planned tax cut in China, the issuance of corona bonds in Japan, tax incentives for certain sectors of the economy against the background of an increase of PIT rate in Korea. The study of fiscal policy during the Covid-19 pandemic based on data from national financial statistics is of interest for future research.

Historically, the growth of intellectual capital has been associated with the trend of an increasing market capitalization of firms, but in practice the consequences of investing in companies that use intellectual capital are often not clear. Studying the relationship between intellectual capital and the ability of companies to generate a stable revenue as an indicator of investment attractiveness is becoming a relevant area of research. The purpose of this article is to study the influence of the intellectual capital of companies on their performance, and, consequently, on possible decisions of investors. The main hypothesis was an assumption about positive significant impact of the dynamic and static structural, relational and human capital of companies on the company's ability to generate revenue and retain a certain market share throughout the year, and, consequently, demonstrate its attractiveness to potential investors. Research method: regression analysis using logistic models, based on proposed models. The likelihood of the high performance of companies is determined under the influence of intellectual capital components, which would determine potential positive decisions made by investors using financial indicators, such as revenue and market share. In contrast to previous studies, we distinguish between static and dynamic elements of intellectual capital in the models to assess the likelihood of high performance. The hypotheses about the influence of the elements of intellectual capital on the company's revenue and their ability to retain market share, which together are indicators of performance reflecting the investment attractiveness of companies, were confirmed. The results show a moderate positive relationship between revenue, market share and quality metrics for static and dynamic intellectual capital. Elements of relational and structural capital play a key role in achieving performance.

Entrepreneurship is now considered to be an urgent solution for handling large pools of young graduates around the world. These crucial situations where universities are creating an excess number of graduates as compared to jobs availability increase the pressure on graduates as well as policy makers and educators. Entrepreneurship in this case does not only handle the burden of the unemployed among the youth but also positively improves the economic development of the country’s economy. In becoming entrepreneurs, graduates do not only create jobs for themselves but for other as well and play a vital role in the development of the economy. This paper explains gender-based entrepreneurship intentions amongst students of Russia and China (3 universities in China, 3 in Russia). A questionnaire was developed to find the impact of different behavior factors on male and female students of Russia and China. In terms of methodology, the quantitative technique was used to collect the data. The entrepreneurial spirit is explained after analyzing the data from three universities in each country. The six universities numbering 468 student respondents were analyzed through Statistical Package for the Social Sciences. To find out the association amongst different variables, multiple regression and correlation technique were used. The results also show an association of gender with entrepreneurship in students in both countries. However, in case of Russia male respondents showed higher intention than female respondents. To maintain the same role of male and female members in the society, development suggestions for educators and policy makers are presented.

Published: March 2021

PURPOSE: Cancer is a disease affecting millions of people and one of the primary causes of death worldwide like cardiovascular diseases. Nonpharmacological and nonoperative methods such as proper exercise-intervention, nutrition, maintaining the activity of daily living (ADL), psychological methods can also improve the physical function, cancer progression, and health-related quality of life (HRQOL). However it is extremely important, little light shed on the impacts of exercise-intervention on cancer prevention and treatments. Therefore, the purpose of this study was to analyze the impacts of nonpharmaceutical approaches such as diverse exercise-intervention on cancer prevention and treatments with psychological and physiological health for cancer patients. Moreover, this paper wants to combine knowledge regarding the many experimental papers and systemic reviews of cancer researches and exercise intervention liter-ature.METHODS:A meta-analysis and systemic reviews of the impacts of an exercise intervention on cancer prevention and treatments were conducted to the PRISMA guidelines. 20 research articles were selected for final inclusion and extraction. And electronic analysis such as PubMed, Google scholar was carried for this study up to May 2020. The search keyword was ‘exercise-intervention and cancer’.RESULTS: We can suggest that physical exercise-intervention might be a suitable combination partner to exercise-related immune therapy in the prevention, delay, and treatment of cancer patients. Moreover, physical exercise-intervention directly enhances the QOL, ADL, healthy life, and even resilience of cancer patients.CONCLUSIONS: Therefore, these exercise interventions can be effective at reducing cancer symptoms, and enhancing cancer treatments for diverse and many cancer patients. Reversing low muscle mass can enhance cancer therapy outcomes and mortality. Nutrition strategies also might be helpful. A Follow-up study about specific high-quality tailoring exercise-intervention program on counteracting cancer symptoms, cancer prevention and treatment, physiological and psychological health and HRQOL is urgently needed in this area.

PURPOSE:This study aimed to identify differences in ankle laxity in chronic ankle instability (CAI), coper, and control groups, and a correlation between ankle laxity, self-reported function, and perceived instability.METHODS: Sixty-six participants (22 CAI patients, 22 copers, and 22 controls) selected by recommendations of the International Ankle Consortium volunteered for this study. Foot and Ankle Ability Measure Activities of Daily Living (FAAM-ADL), FAAM-Sports, and Ankle Instability Instrument (AII) were used to assess participants’ self-reported function and perceived instability. The FAAMADL and FAAM-Sports are reported as a percentage. Higher scores indicate better function. The AII is reported as “yes” responses while more “yes” responses indicate higher instability. Three trials of anterior/posterior (A/P) displacement and inversion/eversion (I/E) displacement were assessed by an instrumented ankle arthrometer. Greater displacement indicates higher laxity. The ankle positioned in sagittal- and frontal-plane neutral while A/P and I/E displacement were assessed with 125 N and 4 N-m, respectively. The means of three trials were used for data analysis. One-way ANOVA and Tukey post-hoc comparisons (α=0.05) were performed to identify differences in ankle laxity between groups. Pearson correlation analysis was performed to identify a relationship between ankle laxity, self-reported function, and perceived instability.RESULTS: CAI patients show greater A/P displacement compared to control group (p<.03), and greater I/E displacement compared to coper and control groups (p<.03). Several positive and negative correlations were found between ankle laxity, self-reported function, and perceived instability (p<.00).CONCLUSIONS: As self-reported function and perceived instability are correlated with greater laxity (I/E displacement), improving static stability (ankle laxity) may play an important role in improving perceived ankle function and instability in CAI.

Abstract We carried out greenhouse experiment to evaluate the effect of silicon (Si) on growth and mineral nutrition of yellow passion fruit (Passiflora edulis) submitted to saline stress in a nutritive solution. The experiment comprised a completely randomized design in a 5x4 factorial scheme: five NaCl concentrations (0; 7.5; 15; 30 and 60 mmol L-1) and four SiO2 concentrations (0; 0.5; 1.0 and 1.5 mmol L-1) with four replicates. At the end of 35 days, we measured stem diameter, leaves, stem, and roots dry matter, as well as the macronutrient, Na, Cl, and Si leaf accumulation in plants. In most cases, the increase in NaCl supply in a nutritive solution reduced the dry matter of roots, stem, and leaves. The SiO2 supply attenuated the effect on higher tested saline stress (30 and 60 mmol L-1 NaCl) on roots and stem dry matter. The application of 0.5 mmol L-1 of SiO2 reduced the deleterious effect of salinity on all macronutrients absorption in yellow passion fruit cultivated in a nutritive solution.

ABSTRACT The study aimed to estimate the evapotranspiration of banana (Musa spp.) in an irrigated perimeter of the municipality of Barbalha, CE, Brazil, using the Surface Energy Balance Algorithm for Land (SEBAL) model and to compare these results with those estimated using the Penman-Monteith method. Landsat-8 OLI/TIRS satellite images of May 22, 2016, August 10, 2016, and October 29, 2016 and data on temperature, relative humidity, wind speed and solar irradiance, obtained from an automatic weather station, installed close to the experimental area were used. The bands were stacked, and the stacked images were cut, then mathematical operations and evapotranspiration estimation were performed, whose actual daily banana values, estimated by the SEBAL algorithm, were 4.70; 5.00 and 6.50 mm, respectively, for May 22, August 10, and October 29, 2016. Comparing the daily ETr given by SEBAL with that obtained by the Penman-Monteith method, absolute errors of 0.26, 0.44, and 0.64 mm d-1 were observed for May 22, August 10, and October 29, 2016, respectively. These errors are within the ranges accepted in the literature.

ABSTRACT Salinity is one of the factors that most limit agricultural yield in the Brazilian semi-arid region. In this context, the present study aimed to evaluate the leaf gas exchange and biometric characteristics of accessions of the Saccharum complex subjected to salt stress. The experiment was carried out in a greenhouse, installed at Embrapa Semiárido, in Petrolina, PE, Brazil. The experimental design was in randomized blocks, with the treatments represented by 19 accessions belonging to different genera/species, being 10 accessions of Saccharum officinarum (BGCN 6, BGCN 91, BGCN 104, BGCN 127, BCGN 90, BGCN 101, BGCN 102, BGCN 118, BGCN 125 and BGCN 122), two accessions of Saccharum spp. (BGCN 87 and BGCN 89), one accession of Saccharum hybridum (BGCN 88), one accession of Saccharum robustum (BGCN 94), four accessions of Erianthus arundinaceus (BGCN 117, BGCN 119, BGCN 120 and BGCN 123) and one accession of Miscanthus spp., with three repetitions. Biometric characteristics, chlorophyll index and leaf gas exchange of the accessions were evaluated when they were subjected to irrigation with salinized water (6.0 dS m-1). E. arundinaceus accessions (BGCN 120 and BGCN 123) showed the highest photosynthetic rate, transpiration rate, plant height and leaf length, indicating greater adaptability to salt stress and could be promising in breeding programs.
