Authors: Zhukovytskyy I. V. , Kliushnyk I. A.
Published: May 2017

Purpose. The article provides for finding solution to the problem of developing and improving the means for measuring tachometric data of the previously created information and measuring system for testing hydraulic locomotive transmission by substantiating the optimal sensor design and signal processing algorithms. At the same time first of all it is necessary to start from the possibility of modifying the already existing test bench for hydraulic locomotive transmissions at the Dnipropetrovsk diesel locomotive repair plant «Promteplovoz». Methodology. In the work, the researchers proposed a methodology for modifying the sensor design and the algorithm for processing its signals. It is grounded on previous developments of tachometric sensor of the optical type on the basis of D-2MMU-2 sensor of the microprocessor automated test bench system of hydraulic locomotive transmission in the locomotive repair plant conditions. Selection of the necessary measurement algorithm and the number of sensor teeth is substantiated by calculating instrumental and methodological errors. Also, the studies aimed at identifying the source of interference in the measurement of rotational speed are described and solution for its elimination has been found. Findings. For the designed rotation speed sensor of the optical type based on the existing D-2MMU-2 sensor, the authors analyzed the dependence of the methodological and instrumental errors. Based on the obtained data more rational variant of the rotation speed calculation algorithm is proposed, and the number of teeth of the sensor disk is justified. Further, the main source of measurement interference was established and a method for improving the hardware of the hydraulic locomotive test bench was proposed. Originality. There were conducted the studies according to the methodological and instrumental errors of the designed rotation speed of sensor. The mechanisms of interference filtering arising from the sensor rotation speed fixing were proposed. Additional studies have shown the need for a hardware revision of signal conditioner scheme. Practical value. Conducted studies make it possible to establish a rational number of sensor disk teeth, which allows improving the measurement algorithm. It was also performed a hardware improvement of signal conditioner scheme from the sensor, helping to get rid of interferences. The results of measurements in studies are the initial data to perform further studies in order to determine the technical condition of hydraulic transmission UGP 750-1200 during factory testing after repair.

Structural characterization of magnesium-substituted nickel ferrite nanoparticles
Authors: De Manojit , Bera Soumen , Tewari Hari Shanker
Published: May 2017

The present paper reports the synthesis of magnesium-substituted nickel ferrite (NiFe(2−x)Mg x O4) (x = 0·15, 0·30, 0·45 and 0·60) using the autocombustion technique with particle size in the nanometer range. As-prepared samples were sintered at two different temperatures (600, 900°C). In the present investigation, it has been observed that with increase in sintering temperature, the estimated bulk densities of the materials increase. The X-ray diffraction patterns of the samples show the formation of single-phase materials, and the crystallite size and lattice parameter are estimated. From the Raman spectra, the Raman shift of magnesium-substituted nickel ferrite is comparable with the experimental values reported in literature. The Raman spectra exhibit five Raman active modes (A1g + Eg + 3T2g) which are expected in the spinel structure. The wide usefulness of spinel ferrites fascinated the researchers to study the properties of these materials to find the controllable parameters to synthesize materials for desired applications.
A mixed frontier model for urban bus performance evaluation
Authors: Zhang Kaisheng , Xu Ya , Sun Daniel (Jian)
Published: May 2017

Bus demand fluctuation at different time periods is one of the most intangible problems for bus operators, which seriously affects operational efficiency. A good knowledge of performance variation at different periods is helpful in developing an effective transit schedule. The aim of this study is to evaluate the efficiency of an urban bus operation at different periods using a mixed frontier model and to explore a better operating strategy which is adaptive to bus demand fluctuation. A mixed data envelopment analysis–stochastic frontier analysis (DEA–SFA) model is proposed, in which multiple outputs are aggregated by the DEA model, and then the technical efficiency is calculated by SFA. The model deals with multiple outputs while considering the stochastic factor simultaneously, so as to ensure model practicability. Using field data from Shanghai Transit Route 55, this study evaluates efficiency at different periods by analysing various aspects. The results indicate that the model effectively describes the characteristics of the bus line efficiency with time period changes, which provides an innovative perspective to solve the operational problem of the urban transit system.

MUTUAL INTELLIGIBILITY OF MALAY- AND SWEDISH-ACCENTED ENGLISH: AN EXPERIMENTAL STUDY
Authors: Jeong Hyeseung Jeong , Thorén Bosse , Othman Juliana
Published: May 2017

In using English as an international language (EIL), one important issue is mutual intelligibility among EIL speakers from different language backgrounds. The present study investigates the cross-linguistic intelligibility of Malay-accented English and Swedish-accented English, regarding the three phonetic features – word stress pattern, consonant clusters, and long vowel in particular. We prepared 15 English statements that are evidently true or false if understood, and examined to what extent the three phonetic features are related to 30 Swedish and 38 Malaysian listeners’ understandings of the statements read by a speaker from the other language group. We compared the Malaysian and Swedish listeners’ answers given with understanding as well as processing time to respond. The listeners’ own accounts of their struggles in understanding the speakers’ pronunciations were also analyzed. Results show that Malaysian listeners easily understood Swedish-accented English, while Swedish listeners struggled to understand Malay-accented English. The difference between the two groups of listeners seems to be closely related to the degree of the realization of the three phonetic features by the speakers as well as to the degree of the use of these features as perceptual cues by the listeners. Based on the findings, we discuss potential phonetic core features of EIL for intelligibility and some pedagogical implications for teaching English pronunciation to the learners of the language.
INVESTIGATING TEACHERS’ PROFESSIONAL COMPETENCE: A SYSTEMIC FUNCTIONAL LINGUISTIC ANALYSIS OF TEACHERS’ REPORT TEXTS
Authors: Sudarsono Sudarsono M. I. , Yunitasari Devi , Gunawan Muhammad Handi
Published: May 2017

This research aims at observing the teachers’ professional competence by investigating the report texts written by three English teachers in a junior high school in terms of their schematic structures and linguistic features. To achieve this aim, a qualitative case study design involving analysis of English teachers’ report texts and interviews with these English teachers was employed in this research. The results of this research showed that generally the three English teachers have demonstrated sufficient ability in applying appropriate schematic structures and linguistic features relevant to the criteria of a report text. However, the results of this research also indicate that some improvements in understanding and writing a report text, especially in terms of schematic structure, linguistic features, and theme progressions, are needed to enhance the teachers’ subject matter content knowledge about report text.
LEXICO-STYLISTIC CHOICES AND MEDIA IDEOLOGY IN NEWSPAPER REPORTS ON NIGER DELTA CONFLICTS
Authors: Ononye Chuka Fred
Published: May 2017

Media reports on Niger Delta (Henceforth, ND) conflicts have reflected a relationship between lexico-stylistic choices and media ideologies. The existing media studies on the discourse have predominantly utilised pragmatic, stylistic and discourse analytical tools in presenting and labelling discourse participants and/or their ideologies, but neglected how media ideologies can be revealed through lexico-stylistic choices made in the reports. This paper therefore examines the lexico-stylistic choices in the reports in order to establish their link to specific ideological goals of the newspapers in relaying the conflict news. Forty reports on ND conflicts, published between 2003 and 2007, sampled from two ND-based (The Tide and Pioneer) and two national (The Punch and THISDAY, labelled) newspapers, were subjected to stylistic and critical analyses, with insights from structural (relational) semantics and aspects of stylistics discourse. Two broad lexical stylistic choices are identified, including paradigmatic (61.8%—indexed by synonymous, antonymous, hyponymous, colloquial, and register items, and coinages) and syntagmatic (38.2%—marked by collocations, metaphors, pleonasms, and lexical fields) features. The features are utilised for three ideological ends; namely, picking out and framing participants as perpetrators of the violence in the discourse, evaluating specific entities and their roles in the conflicts, and reducing the impact of the activities of the news actors. Although there are overlaps, the evaluative ideology is largely associated with the national newspaper, the impact reduction ideology with the ND-based newspapers, while the framist ideology is observed in the two sets of newspapers. With these findings the study has added the lexical stylistics angle to the existing scholarship on ND conflict news discourse. Thus, the newspaper reports on ND conflicts are motivated by their ideological goals to change the reader’s outlook on the issues relating to the conflicts.
GENDER IN EFL CLASSROOM: TRANSITIVITY ANALYSIS IN ENGLISH TEXTBOOK FOR INDONESIAN STUDENTS
Authors: Emilia Emi , Moecharam Nicke Yunita , Syifa Iva Laela
Published: May 2017

This paper is concerned with the topic of gender in EFL classroom, particularly in Indonesian context. Owing to the framework proposed by Sunderland (1992), the paper focuses on the discussion of gender in classroom materials, i.e. English textbooks. Selected reading passages were analyzed within the framework of Transitivity system of functional grammar (Halliday & Mathiessen, 2004; Haliday & Mathiessen, 2014). The Processes in the texts (e.g. travel, walk, and climb) reveal that males were perpetually constructed as ‘adventurous’, ‘risk taker’, ‘active’, ‘independent’, and ‘capable’. Meanwhile, the Processes also indicate that the females were shaped as more ‘passive', ’expressive’, ‘nurturing’, and ‘unassertive’ than their male counterparts (Blackstone, 2003; Evans & Davies, 2000). The findings suggest that the gender roles were presented in an asymmetrical manner. The paper provides recommendation in terms of how both teachers and students can develop gender awareness in the classroom practices through the use of the textbooks.
A hazai műkereskedelem tipológiája és térbeli jellegzetességei Budapest példáján

A műkereskedelem hazánkban mindmáig a kiskereskedelem kevésbé feltárt szegmensei közé tartozik. Ugyanakkor a téma aktualitását igazolja, hogy bizonyos társadalmi rétegek jelentős összegeket fordítanak műtárgyak vásárlására és fektetik be felhalmozott jövedelmük egy részét antik és kortárs vagyontárgyakba. A műtárgypiacon számos galéria, aukciósház és régiségbolt jelenik meg, és az antikváriumok is fontos résztvevőknek tekinthetők.Jelen tanulmány célja a budapesti műkereskedelem klasszifikációja és térbeli sajátosságainak bemutatása. A primer adatgyűjtésre épülő kutatás a fővárosi műkereskedéseket vizsgálja, saját terepi megfigyelésekkel és félig strukturált interjúk elkészítésével. Az üzletek és kereskedőházak elhelyezkedésének megjelenítése és elemzése térinformatikai szoftver alkalmazásával történt.A műtárgypiac szereplői különböző típusokba sorolhatóak a profil, az értékesítés helye, az árpolitika és a kínálat alapján. Megfigyelhető, hogy a galériák és aukciósházak Budapest legelegánsabb hagyományos bevásárlónegyedében helyezkednek el, a másodlagos bevásárlózóna jellemzően az antikváriumoknak és a régiségboltoknak ad otthont. Az egyes típusok térbeli elkülönülése számos tényezővel magyarázható: a bérleti díjak nagyságával, történeti előzményekkel, agglomerációs előnyökkel.

Authors: Vörös Tünde
Published: May 2017

A tanulmány a fizikai aktivitás növelése révén elérhető társadalmi és gazdasági haszon lehetőségeire mutat rá Kelet-Közép-Európában. A tanulmány a fizikai aktivitás, az egészségi állapot és a társadalmi-gazdasági fejlődés közötti kapcsolatot elemzi általánosságban és Kelet-Közép-Európa országaiban. Elsőként a dolgozat elméleti keretét adó kapcsolatrendszert tárgyaljuk, majd Kelet-Közép-Európa népességének egészségi állapotát elemezzük a születéskor várható élettartam és egészséges élettartam alapján, illetve a lakosság fizikai aktivitását vizsgáljuk európai viszonylatban. A tanulmány mint lehetséges megoldást vizsgálja a szabadidősportban, a sportolási hajlandóság növelésében rejlő lehetőségeket. A fizikai aktivitás növelésének társadalmi és gazdasági hasznát (pl. az egészségi állapot javulása, a várható élettartam emelkedése, a termelékenység növekedése, a központi költségvetés terheinek csökkenése, a társadalmi tőkére gyakorolt hatás) az elméleti összefüggések feltárása mellett kvantitatív elemzésekkel is kiegészítjük. Olyan számszerűsített összefüggésekre mutatunk rá, mint például a sportolási hajlandóság és a mentális egészség kapcsolata, valamint a sportolási hajlandóság és a gazdasági teljesítmény közötti összefüggés. A sport társadalmi beágyazottságát klaszteranalízis és statisztikai hipotézisvizsgálatok segítségével elemezzük európai országok mintáján. Eredményeink alapján arra következtethetünk, hogy azokban az országokban, ahol a sport a társadalom mindennapjainak szerves részét képezi, a vizsgált társadalmi-gazdasági mutatók (pl. GDP/fő, HDI, egészségi állapot) kedvezőbben alakulnak. Végül az egy klaszterbe tömörülő kelet-közép-európai régió országaiban az alacsony fizikai aktivitás okait is vizsgáljuk.

Ethical Competencies and the Organizational Competency ‘Responsible University Social Innovation’: looking at new ways of understanding universities and the competency-based education model in the context of significant social changes in Latin America
Authors: Villar Olaeta Javier
Published: May 2017

Ethical competencies are included in all competency-based education models and are considered essential for the professional preparation of students, especially in terms of their professional conduct and workplace preparedness. As such, the Tuning Academy, along with incorporating ethical competencies in its group of generic competencies, also considers the organizational competency Responsible University Social Innovation (RUSI) as part of its Tuning ALFA II Latin América project. This competency, in the area of organizational character, addresses innovation in the context of social responsibility, which it assumes each university should have, in terms of ethical responsibility toward the members of a community. This concept incorporates the equal relationship between the university’s internal community and civil society. By means of interviews with experts in the areas of service-learning, social responsibility, and ethical civil and professional education from the University of Deusto and the Zerbikas Foundation, this article discusses the connection and implementation of both generic ethical competencies and the RUSI organizational competency in higher education in order to respond to the new challenges to professional training in today’s world, all of which ultimately assumes a change in universities’ understandings of themselves as institutions and the role of higher education in general.
Students applying their knowledge of material science in problem-solving: implications for competence based-learning at the University of Zimbabwe
Authors: Kwaira Peter
Published: May 2017

This study involved a class of serving teachers in their second year of a Bachelor of Education degree programme, in which one of the pre-requisite courses covered during first year was ‘Principles of Material Science (PMS). At the time of study, they were studying ‘Machine-shop Practice’ (MsP); a course based on the Design and Technology (D&T) approach, in terms of teaching and learning. They were required to solve practical-technical problems through hands-on practical activities, supported by relevant ancillary theory. In practice, during such activities, students are expected to demonstrate the ability to apply their knowledge of Material Science (MS) in various ways; for example, in the choice of materials for given projects aimed at solving specific problems and in the methods of working such materials. Now given this background, the problem was therefore to determine the extent to which students applied their knowledge of MS in solving selected problems under MsP. Data were gathered through interviews, discussions, observations and document analysis. Findings showed students being able to apply their knowledge of MS effectively during problem-solving under MsP; thereby, qualifying their learning as having been outcome-based in nature.

Published: May 2017

A pectina é um polissacarídeo complexo, que atua como agente geleificante, espessante e estabilizante na composição de diversos produtos. A casca do maracujá possui elevado nível de pectina, cujo método convencional de extração é a ebulição utilizando ácidos fortes. O presente estudo objetivou explorar um novo método de extração utilizando ácidos fracos. Buscando esse propósito, a pectina da casca de maracujá foi obtida por meio de extração assistida por ultrassom, utilizando solução de ácido cítrico. Os experimentos foram conduzidos visando avaliar o efeito das variáveis experimentais (razão amostra:solvente, temperatura e tempo) no rendimento de pectina. Os resultados demonstraram que a extração conduzida com razão amostra:solvente de 1:50 (m/v), temperatura de 50 °C e tempo de 90 min proporcionou a obtenção de 26,45% de pectina. Nessas mesmas condições experimentais a pectina foi extraída por método convencional para efeito comparativo, o qual permitiu a obtenção de 21,06% de pectina. Portanto, o uso do ultrassom promoveu a obtenção de melhores resultados, visto que proporcionou o aumento de 25% no rendimento. O grau de esterificação foi determinado apenas para amostras obtidas por ultrassom, as quais foram classificadas com alto grau de metoxilação (81,93%).

ABSTRACT

Pectin is a complex polysaccharide, which acts as a gelling agent, thick and stabilizing in the composition of various products. The passion fruit peel has a high level of pectin, whose conventional method of extraction is boiling using strong acids. The present study aimed to explore a new extraction method with the weak acids. For this purpose, a pectin from the passion fruit peel was obtained by ultrasound-assisted extraction, using citric acid solution. The experiments were conducted with the objective of evaluating the effect of experimental variables (analysis procedure: solvent, temperature and time) on pectin yield. The results demonstrated that the extraction was carried out on the basis of a solvent criterion of 1:50 (m/v) at a temperature of 50 °C and the time of 90 minutes provided a yield of 26.45% pectin. In these same experimental conditions the pectin was extracted by conventional method for comparative effect, which allowed a obtainment of 21.06% pectin. Consequently, the use of the product was promoted to obtain better results, which gave rise to a 25% of increase in yield. The degree of esterification was determined only for samples obtained by ultrasound, which were classified with high degree of methoxylation (81.93%).
THE EFFECT OF ADMINISTERING RHIZOME EXTRACT OF CURCUMA (Curcuma Xanthorrhiza Roxb.) AT VARIOUS DOSES ON THE THICKNESS OF VAGINAL EPITHELIUM IN MICE (Mus Musculus) EXPOSED TO MSG
Authors: Atmaja Ria Ramadhani Dwi
Published: May 2017

The usage of Monosodium Glutamate (MSG) as flavour enhancer in food is increasing and has reached alarming condition. Excessive consumption of MSG results in the formation of a number of free radicals in the body and affects the function of hypothalamus. A disturbed hypothalamus results in the decline of estrogen levels, and in turn, this estrogen deficiency causes a decrease in vaginal epithelial proliferation in which epithelial cells become thinner. Giving antioxidants might help to address these problems. One of the plants that is rich in antioxidant and grow in mass in Indonesia is curcuma. This study is aimed at analyzing the effect of giving curcuma extract (Curcuma Xanthorrhiza Roxb.) with varying doses on the thickness of vaginal epithelium in mice that are exposed to MSG. The research design employed in the study is true experimental posttest only control group by using 5 groups, namely: K1 (CMC-Na), K2 (MSG), P1 (MSG + curcuma rhizome extract dose of 0,4mg/gr BW), P2 (MSG + curcuma rhizome extract dose of 0,8mg/gr BW), P3 (MSG + curcuma rhizome extract dose of 1,2mg/gr BW). Vagina of each mouse was taken and studied to measure its epithelial thickness by using a 40x magnification on Olympus micrograph microscope. Data were then analyzed using One Way ANOVA. The results show that there is no significant difference in the thickness of vaginal epithelium in each treatment (ρ-value 0.341). Therefore, it can be concluded that the extract of curcuma rhizome does not have a significant influence on the thickness of vaginal epithelium in mice that are exposed to MSG.

Monte Carlo calculations were carried out where compounds with positron-emitters radionuclides, like FDG (18F), Acetate (11C), and Ammonium (13N), were incorporated into a soft tissue volume, in the aim to estimate the type of particles produced their energies, their mean free paths, and the absorbed dose at different distances with respect to the center of the volume. The volume was modeled with a radius larger than the maximum range of positrons in order to produce 0.511 keV annihilation gamma-ray photons. With the obtained results the absorbed dose, in various organs and tissues able to metabolize different radiopharmaceutical drugs, can be estimated. The code used was GEANT4.

ResumenSe sintetizó la perovskita LaFe0,2Co0,8O3, usando el método de polimerización con ácido cítrico. Las caracterizaciones de los precursores con espectroscopia infrarroja (FT-IR), ultravioleta visible (UV-vis), y análisis térmicos (TGA-DTA), revelaron la presencia de especies tipo citrato y la consolidación de una estructura estable a partir de los 700°C. Análisis de difracción de rayos X (XRD), energía dispersiva de rayos X (EDX), microscopia electrónica de barrido (SEM) y espectroscopia Raman, confirmaron la consolidación de un sistema cristalino tipo LaCoO3 de fase simple romboédrica, una superficie homogénea y porosa, y tamaño de partícula nanométrico. La evaluación mediante espectroscopia de impedancias (IS), desde temperatura ambiente hasta 900°C, mostró un material con alta conductividad eléctrica y comportamiento semiconductor. AbstractThe perovskite LaFe0.2Co0.8O3 was synthesized using polymerization with citric acid method. Characterizations of the precursors with Fourier transform infrared spectroscopy (FT-IR), ultraviolet visible spectroscopy (UV-vis), and thermal analysis (TGA-DTA), revealed the presence of species citrate type, and formation of a stable structure from up to 700°C. Analysis by means of X-ray diffraction (XRD), energy dispersive X-ray (EDX), scanning electron microscopy (SEM) and Raman spectroscopy, confirmed the consolidation of a crystal system LaCoO3 type, of rhombohedral single phase, with homogeneous and porous surface and nanometer particle size. The evaluation by impedance spectroscopy (IS) from room temperature to 900°C, showed a material with good electrical conductivity and semiconductor type behavior.

The aim of this article is to compare the performance of linear and non-linear control in the case of a series wound DC motor. The research was focused on determining when the differences in the performance between these controllers are significant. The comparison was made on the MS150 feedback module and it included the phases of parameter estimation for the linear and the non-linear models, the statistical validation of these models and the design and implementation of the controllers. In order to make the comparison there were defined two performance criteria respectively based on the tracking error and on the control effort. These criteria were applied by considering three scenarios defined according to the range in which the velocity set point is varied. In the first scenario, the reference velocity remained constant and equal to the value of the operation point around which the linear model was obtained (60 %). In the second and third scenarios the reference velocity was respectively increased from 40% to 60% and from 20% to 100%. From the experimental tests it was observed for the scenarios two and three that the tracking error and the control effort for the linear controller are superior to the non-linear ones.  While for the first scenario, the linear controller presents a lower tracking error with an approximately equal control effort . From this work it was concluded that for reference velocities that are close to the operation point, the linear controller presents a significant advantage over non-linear controller.

Virtual Reality Simulation as a Tool to Monitor Surgical Performance Indicators: VIRESI Observational Study
Authors: Muralha Nuno , Oliveira Manuel , Ferreira Maria Amélia , Costa-Maia José
Published: May 2017

Introduction: Virtual reality simulation is a topic of discussion as a complementary tool to traditional laparoscopic surgical training in the operating room. However, it is unclear whether virtual reality training can have an impact on the surgical performance of advanced laparoscopic procedures. Our objective was to assess the ability of the virtual reality simulator LAP Mentor to identify and quantify changes in surgical performance indicators, after LAP Mentor training for digestive anastomosis.Material and Methods: Twelve surgeons from Centro Hospitalar de São João in Porto (Portugal) performed two sessions of advanced task 5: anastomosis in LAP Mentor, before and after completing the tutorial, and were evaluated on 34 surgical performance indicators.Results: The results show that six surgical performance indicators significantly changed after LAP Mentor training. The surgeons performed the task significantly faster as the median ‘total time’ significantly reduced (p < 0.05) from 759.5 to 523.5 seconds. Significant decreases (p < 0.05) were also found in median ‘total needle loading time’ (303.3 to 107.8 seconds), ‘average needle loading time’ (38.5 to 31.0 seconds), ‘number of passages in which the needle passed precisely through the entrance dots’ (2.5 to 1.0), ‘time the needle was held outside the visible field’ (20.9 to 2.4 seconds), and ‘total time the needle-holders’ ends are kept outside the predefined operative field’ (88.2 to 49.6 seconds).Discussion: This study raises the possibility of using virtual reality training simulation as a benchmark tool to assess the surgical performance of Portuguese surgeons.Conclusion: LAP Mentor is able to identify variations in surgical performance indicators of digestive anastomosis.

Authors: Piovesan Flávia , Fachin Melina Girardi
Published: May 2017

Este artigo aborda o tema da educação em Direitos Humanos e o quão importante é esse instrumento para o desenvolvimento de uma cultura de paz e para o fortalecimento das instituições democráticas. A educação possui um potencial transformador, especialmente nessa seara, já que ressalta a dimensão preventiva do discurso protetivo. É a partir dessa perspectiva que o presente artigo parte, ressaltando os marcos normativos sobre a temática da educação nos âmbitos interno e internacional. No plano global, confere-se especial destaque para o Programa Mundial para Educação em Direitos Humanos do sistema ONU; no âmbito interno, há registro importante dos esforços para instituir uma política pública voltada à educação em Direitos Humanos. Tais empenhos resultaram, no âmbito do Poder Executivo, no Pacto Universitário pelos Direitos Humanos, que propõe alterações do modelo educacional tradicional a fim de realçar o caráter libertário e fortalecer a possibilidade de novos discursos sob a ótica dos Direitos Humanos.

RESISTÊNCIA DO SOLO EM CULTIVO DE TABACO COM DIFERENTES FORMAS DE MANEJO NA REGIÃO SUDESTE DO PARANÁ
Authors: Antoneli Valdemir , Caian de Jesus Fabio , Bednarz João Anésio
Published: May 2017

O cultivo do tabaco é uma alternativa rentável para as pequenas propriedades da região Sudeste do Estado do Paraná, principalmente por ser cultivado em áreas impróprias para a agricultura (solos rasos e declividade acentuada). Nas áreas com restrições ao uso, o tabaco é cultivado sob plantio convencional e nas áreas mais planas utiliza-se o plantio direto. A variação na forma de plantio pode influenciar na resistência do solo. O objetivo deste trabalho foi identificar a influência do manejo do solo na resistência do solo em áreas de cultivo de tabaco com plantio convencional e plantio direto. Foram identificados 10 pontos para o monitoramento da resistência do solo em cada forma de plantio com coletas quinzenais entre setembro (início do plantio) a fevereiro (término da colheita). Foi utilizado o método de perfis transversais entre as linhas de plantio. As mensurações foram realizadas com um penetrômetro de bolso. Ao término da pesquisa foi observado que as atividades diárias realizadas no cultivo do tabaco influenciam na resistência do solo, mesmo com formas diferentes de cultivo.
