Authors: BAŞBOĞA İbrahim Halil , ATAR İlkay , KARAKUŞ Kadir , YÜCE Özcan , MENGELOĞLU Fatih
Published: December 2018

Aim of study: The objectives of this research were to determine the effectiveness of

melamine impregnated paper (MIP) waste as an adhesive in the particleboard

manufacturing and effects of the MIP waste using as an adhesive on the some

technological properties of particleboard.

Area of study: To determine the mechanical, physical and formaldehyde

content of particleboards manufactured with different resins (MIP waste, neat

MIP resin).

Material

and Methods: In this study, particleboards were produced with utilizing MIP waste and

neat MIP resin. No additional adhesive was used for MIP waste. Two different

types of mixture of Turkish red pine (90%) and poplar wood (10%) particles

(fine and coarse) were used. Eight different particleboard

groups and three particleboards with three layers (two surface layers and one

core layer) were manufactured for each group in hot press.

Main

results:

As results of this

study, amount of adhesives had significant effect on panel properties. With the

increasing of both adhesive rates (MIPW and neat MIP resin), mechanical and

physical properties of particleboard were improved. However, formaldehyde

content values were worsen with the increasing

of both adhesive rates. The best result for MIPW and neat MIP resin were

obtained when highest rates of them (25% and 13%, respectively) were used.

Research

highlights:

Particleboards were successfully manufactured with using of the MIP waste as

adhesive. Although the MIPW (25%) boards were provided lower mechanical and

physical values than neat MIP resin (13%) boards, they were satisfied the most

of standard requirements.

Biologia Molecular como ferramenta de detecção fúngica no sangue: auxílio diagnóstico e redução de gastos
Authors: Siqueira Joao Paulo Zen , De Almeida Margarete Teresa Gottardo
Published: December 2018

Introdução: Os avanços médicos das últimas décadas contribuíram para aumentar a sobrevida de pacientes críticos e com a resposta imune comprometida. Consequentemente, a população em risco de adquirir infecções de origem fúngica também cresceu. Com altas taxas de morbidade e mortalidade, o difícil diagnóstico deste tipo de infecção, em conjunto com terapias ineficazes, gera elevados custos e sobrecarga ao sistema de saúde. Objetivos: Padronizar um método molecular de detecção fúngica diretamente do sangue e avaliar esta técnica comparativamente com a atualmente considerada padrão-ouro (hemocultura), associando aspectos clínicos, tempo de realização das técnicas e os custos envolvidos. Casuística e Métodos: Neste sentido, 94 pacientes com suspeita de infecção de corrente sanguínea foram submetidos a uma técnica de nested PCR para detecção de DNA fúngico. Resultados: A técnica molecular foi positiva em 48,9% das amostras, enquanto que a hemocultura foi positiva em apenas 13,0% dos casos. Esses resultados demonstram uma alta sensibilidade do nested PCR e com um valor preditivo negativo de 100% em pacientes com suspeita clínica de infecção fúngica sistêmica e em situações de risco. O tempo de realização do método e os custos associados a ele, em comparação à hemocultura, também demonstraram seu potencial para uso clínico. Conclusões: Em comparação com a hemocultura, o método padronizado de nested PCR constitui um teste rápido e economicamente viável capaz de descartar uma infecção sistêmica provocada por fungo, podendo facilitar o diagnóstico e evitar terapias ineficientes e caras, diminuir o tempo de internação e os impactos econômicos gerados por esse tipo de infecção.
Imagens do povo em Grande sertão: veredas
Authors: Azevedo Guilherme Zubaran de
Published: December 2018

Resumo: Este artigo tem por objetivo analisar as imagens do povo presentes na obra Grande sertão: veredas, de Guimarães Rosa. Para tanto, propõe-se fazer uma crítica das noções de comunidade e povo, configuradas pelo projeto de nação moderno da década de 1950. A crítica visa repensar o sentido totalizante dessas duas concepções. A leitura de Grande sertão: veredas pretende identificar na obra conceitos de povo e comunidade que escapam às reconfigurações modernas de nação. Nesse sentido, a partir das obras de Roberto Esposito, Didi-Huberman e Giorgio Agamben, analisa-se a população sertaneja não como uma união coesa, mas como uma multiplicidade de singularidades que habitam e convivem numa dimensão comunitária da vida. O domínio do comum é entendido como uma modalidade de ser-com, em que o convívio com o outro não é um reforço da identidade, mas sim uma expropriação de si, das fronteiras da subjetividade. Ao analisar os diversos povos do sertão, inclusive aqueles que foram mortos e cujos sofrimentos são testemunhados por Riobaldo, busca-se pensar num conceito de justiça relacionado com a memória que dá visibilidade a essas populações esquecidas do sertão.Palavras-chave: povo; comunidade; poder.Abstract: This article aims to analyze people images in Grande sertão: veredas (The devil to pay in the Backlands), by Guimarães Rosa. In order to do so, the notions of community and people, shaped by the project of modern nation construction in the 1950s, are criticized. The critique aims to reshape the totalizing sense of these two conceptions. The reading of Rosa’s novel intends to identify concepts of people and community that escape from the modern reconfigurations of nation. Therefore, in the light of Roberto Esposito’s, Didi-Huberman’s and Giorgio Agamben’s works, the backlands population is comprehended not as a cohesive union, but as a multiplicity of singularities that inhabits and coexists in a communitarian life dimension. The common domain is understood as a modality of being-with, in which the cohabitation with the other is not a reinforcement of identity, but an oneself expropriation and of the subjectivity borders. By analyzing the diverse hinterland peoples, including those who were killed and whose sufferings were witnessed by Riobaldo, a concept of justice related to the memory of the forgotten backlands populations is approached.Keywords: people; community; power.

Published: December 2018

El documento analiza si los graduandos de los programas de Administración, bajo cada tipo de modalidad (presencial, a distancia y virtual), cumplieron con la meta de bilingüismo propuesta por el Gobierno colombiano para el 2014. Para esto se emplea una aproximación descriptiva y estadística (pruebas de proporciones paramétricas y no paramétricas) para analizar los resultados del módulo de inglés de la prueba de Estado Saber Pro (2011 - 2017). A partir de lo anterior, se encuentra que sólo 11 de 198 programas de la modalidad presencial a nivel nacional cumplieron la meta en 2014, mientras que sólo 9 de los 41 programas acreditados de la modalidad presencial cumplieron la meta. Estos resultados evidencian la necesidad de que Gobierno revise los alcances de la política pública de bilingüismo.
An Exploration of Inclusivity for Persons with Disabilities in Disaster Risk Management Planning at the National and Local Government Levels in Jamaica
Authors: Carby Barbara , Ferguson Therese , Steele Shaughna-Lee , Maiyaki Zainab
Published: December 2018

The Small Island State of Jamaica is vulnerable to various natural hazards; as a result, it faces threats to its economy, infrastructure, property, and populace. Disaster Risk Management (DRM), including preparedness, mitigation, and recovery, is critical for the nation. Central to this process is information provision and dissemination in order to enhance the public's understanding and management of these hazards.Persons with Disabilities (PWDs) are a significant part of Jamaica's population, who require DRM information in special formats. This exploratory study examines the provisions made for PWDs in DRM at the national and local government levels in Jamaica. Surveys were utilised to gather information from national Government Ministries and local Parish Councils about DRM facilities in place for PWDs, access to DRM information for PWDs, and the extent of PWDs participation in DRM at these levels. Additionally, focus group consultations were held with PWDs from two educational institutions for PWDs to gather their perspectives on provision of information and special facilities for them.Jamaica has taken the appropriate policy and legal steps to recognise the rights of PWDs by being a signatory to the United Nations Convention on the Rights of Persons with Disabilities, as well as developing a national policy and enacting legislation on PWDs. Additionally, government respondents showed a high level of awareness of the necessity of disability inclusion. The results, however, indicate that disability inclusiveness has not been achieved by many government entities charged with responsibility for policy implementation and with the responsibility of setting the example by obeying the country's laws. Recommendations are made to ensure full participation of PWDs in society including equal access to information, equal access to facilities and inclusion in DRM programming and planning.
Indigenous Perspectives of Disability
Authors: Rivas Velarde Minerva
Published: December 2018

This article contributes to the discourse on disability from an indigenous perspective, an area which has not been investigated in any detail. It explores the perceptions of disability and lived experiences of 18 indigenous individuals with impairments from Australia, Mexico and New Zealand. The findings from this research suggest that participants from these countries share some common standpoints, particularly in relation to their disassociation from Western disability discourses and their common experiences of social oppression. This paper calls for further reflection about on-going colonisation and an in-depth analysis of the lack of attention given to this issue within the main models of disability.

Published: December 2018

Background: Post burn contractures are distressingly common and severe in developing nations and considered as a significant problem in developed countries as well. Despite advances in the overall management of burn injuries, severe post-burn contractures continue to be a formidable foe for reconstructive surgeons in developing countries.Methods: The study was carried out in Department of Surgery, Himalayan Institute of Medical Sciences, SRH University, Swami Ram Nagar, Dehradun over a period of 12months. Cases of the post burn contractures attended in the O.P.D were included in the study.Results: Contracture release with split thickness skin grafting STSG in 25 (55.5%) cases. Contracture release with STSG with flap cover was performed in 7 cases (15.5%), contracture release with K wire insertion with coverage was performed in 8 cases (17.7%) and Z plasty was performed in 5 cases (11%).Conclusions: There have been major advances in burn care in the last three decades and the mortality rates have gone down significantly. The management has shifted to improvement of functional outcome and better quality of life. Proper planning of reconstructive procedures, rehabilitation, restoration to pre-injury status and return to society are the goals that the treating team hopes to achieve.

Authors: Sonkar Santosh , Ratre Rajendra , Chandrakar Sandeep , Nanda Utkarsh
Published: December 2018

Background: Gastric cancer (CG) is the fifty most common cancer among males and seventh most common cancer among females in India. Prognosis in gastric cancer is very much related to pathological staging. Over the last decade management of gastric cancer has evolved from surgeon to multidisciplinary approach. Laparoscopy has been proposed as an accurate staging modality in a variety of upper gastrointestinal malignancies.Methods: The present cross-sectional prospective hospital-based study was conducted in the department of surgery, pt. J.N.M medical college Raipur, Chhattisgarh, India, during study period July 2016 to June 2018.  All the patients of endoscopic biopsy proven gastric cancer (50 cases) who presented during study period and satisfied the inclusion criteria underwent investigations like hemogram, renal function tests, liver function tests, CEA, CA 19-9, chest X-ray, CECT Abdomen and pelvis, staging laparoscopy. Standard protocols were followed for CECT abdomen scan, staging laparoscopy. Appropriate management of the cases were done.Results: In this study, most common symptom associated with carcinoma stomach was upper abdominal pain which was present in 42 cases (84%). Most common site for tumor was pylorus in 38 cases (76%). 2nd most common site for tumor was fundus in 8 cases (16%) followed by body in 3 cases (6%) and diffuse in 1 case (2%).  CECT staged 2 cases (4%) as stage I (IA-0, IB-2), 11 cases (22%) as stage II (IIA-3, IIB-8) and 37 cases (74%) as stage III (IIIA- 18, IIIB-05, IIIC-14). Surgery with curative intent was done in 15 cases (30%). In 32 cases (64%) due to disseminated disease as found on staging laparoscopy, surgery was abandoned and patients were sent for Neoadjuvant chemotherapy.Conclusions: Laparoscopy is a valuable technique in staging carcinoma stomach and has an important role in detection of occult extensive intra-abdominal or metastatic disease.

Otras posibilidades para trozos de papel: Hacia un archivo colaborativo de la escena independiente
Authors: Musello Luciana
Published: December 2018

2015 fue un buen año para la nueva escena independiente del Ecuador. Un grupo de bandas vinculadas a la escena indie, un sector de la música local que se agrupó en ciertos festivales y conciertos, generó un poderoso y contagioso movimiento de fans del que yo también era parte. En esa misma época, comencé a trabajar en Radio COCOA (RC), y fue en ese contexto que me fijé en un objeto ubicuo en los conciertos a los que asistía y que, de forma insospechada, configuraba la experiencia de la música en vivo: el setlist. Esos trozos de papel se convirtieron en el motor de una serie de reflexiones y proyectos alrededor de la historia de la escena musical a la que yo pertenecía.

Methods of two-dimensional projection of digital images into eigen-subspaces: peculiarities of implementation and application
Authors:   Electrotechnical University ", Kukharev G. ,   LETI",   (ETU), Shchegoleva N. ,   Electrotechnical University "LETI" (ETU)
Published: December 2018

The history of development of algorithms for projection of digital images into their eigensubspaces using linear methods based on PCA (principal component analysis), LDA (linear discriminant analysis), PLS (partial least squares), and CCA (canonical correlation analysis) is considered. We show that the emergence of new application areas has changed the requirements for the methods, with major changes involving (i) the use of PCA, LDA, PLS and CCA methods for both small and extremely large face image (FI) samples in the initial sets; (ii) a criterion for determining the eigen-basis, which also should provide the solution of a particular problem (the minimum error of face image approximation, etc.); (iii) the applicability of the methods under consideration to the processing of two or more image sets from different sensors or several sets of any number of matrices; and (iv) the possibility of realizing two-dimensional projections of face images (or other numerical matrices) directly into the layers of convolutional neural networks (NN) and/or integrating their functions into the NN as separate blocks. Estimates of the computational complexity and examples of solving image processing problems are also given.

The paper presents a new method for measuring the vortex spectrum (amplitude squares and initial phases) as well as the orbital angular momentum without cuts and splices of the wave front of a vortex array. Such an extension of the measurement capabilities of the combined beam properties is achieved by recording the intensity moments of the light beam as a whole without destroying its internal structure. The correlation coefficient between the initial intensity distribution and the intensity distribution taking into account the experimentally obtained vortex spectrum reaches 91%, which indicates the reliability of the presented method.

Two methods of adaptive median filtering of impulse noise in images
Authors:   North-Caucasus Federal University, Chervyakov N. , Lyakhov P. ,   North-Caucasus Federal University, Orazaev A. ,   North-Caucasus Federal University
Published: December 2018

Two new methods of adaptive median filtering of impulse noise in images are proposed in the paper. The first method is based on the joint application of iterative processing and transformation of the result of median filtering using the Lorentzian function. The second method uses alternative masks of median filter, calculated using the Euclidean metric. This approach has made it possible to reduce the size of the processed area without the loss in quality for low-intensity noise. The experimental part of the article shows the results of comparison of the performance of the proposed methods with the known methods. We used three different images distorted by impulse noise with pixel distortion probabilities ranging from 1 % up to 99 %. The numerical evaluation of the quality of image denoising based on the peak signal to noise ratio (PSNR) and the structural similarity (SSIM) has shown that the proposed method shows a better result of processing in all the cases considered, as compared with the known approaches. The results obtained in the paper may find wide practical applications when processing satellite and medical imagery, geophysical data, and in other areas of digital image processing.

Authors:   Samara National Research University, Chernov V. ,   IPSI RAS – Branch of the FSRC “Crystallography and Photonics” RAS
Published: December 2018

The work continues the author's previous study of positional number systems in finite fields. The paper considers ternary number systems and arithmetic operations algorithms for the representation of elements of finite fields in the so-called ternary reduced number systems, which are reductions of the canonical number systems when mapping the corresponding ring of integers of a quadratic field into some prime field. A classification of finite fields in which such number systems exist is given. It is proved that the reduced ternary number systems exist for most finite prime fields.

In this paper, we introduced the Mainardi beam and indicated its attributes under the Fractional Fourier transform for power variations of Fractional Fourier transform. The results represent that the behavior of the Mainardi beam is similar to that of the Airy beam. The obtained formula is a very powerful tool to describe propagation of a Mainardi beam through the FFT and the FrFT systems. An analytical expression of the Mainardi beam passing through an Fractional Fourier transform system presented. The influences of the Fractional Fourier transform, rational order of the Mittag-Leffler function (Fourier transform of the Mainardi function) on the normalized intensity distribution and characteristics of the Mainardi beam in the Fractional Fourier transform system examined. Power of the Fractional Fourier transform (p) and rational order of the Mittag-Leffler function (q) control characteristics of the Mainardi beam such as effective beam size, number, width, height, and orientation of the beam spot.
Spectral and spatial super-resolution method for Earth remote sensing image fusion
Authors:   Samara National Research University, Belov A. , Denisova A. ,   Samara National Research University
Published: December 2018

In the article we propose a spatial and spectral super-resolution algorithm for a set of multichannel images obtained by various Earth remote sensing detectors. We regard the result of the algorithm as a model of an ideal data source, which has a better accuracy of the observed terrain representation than each of the input images having lower spatial and spectral resolution. The proposed algorithm utilizes a method of gradient descent and applies a refined model of image observation, including both spectral and spatial down-sampling and up-sampling. The article describes an experimental study of the proposed algorithm and a comparison of the quality of its work with bilinear interpolation of low-resolution images. The practical application of the proposed algorithm consists in the joint processing of remote sensing data of various levels, which makes it possible to erase the boundaries that arise from the design differences of imaging sensors.

Published: December 2018

Investigamos a construção marcadora discursiva formada por verbo perceptivo-visual e afixoide, constituinte do esquema [Vpv(X)]md, com base em constructos no português brasileiro contemporâneo. Fundamentados na Linguística Funcional Centrada no Uso, nos termos de Traugott e Trousdale (2013), entre outros, detectamos subesquemas e microconstruções desse esquema maior, com foco em seu nível de vinculação semântico-sintática e produtividade. Constatamos que olhar e ver são as bases verbais, as subpartes centrais que instanciam tais usos, como olhe e veja, enquanto a segunda subparte, quando preenchida, o faz por intermédio de afixóides locativos ou focalizadores, em types como olha só ou vê lá.
Ethos: a construção da imagem de si
Authors: Antunes Claudia Sousa , Pauliukonis Maria Aparecida Lino
Published: December 2018

O objetivo deste artigo é mostrar como a construção da imagem do enunciador (ethos) aparece como estratégia discursiva relevante para o processo de persuasão. O arcabouço teórico do trabalho está alicerçado nas lições de Aristóteles (2005), Perelman e Tyteca (2005), Amossy (2011), Charaudeau (2009) e Maingueneau (2013). O percurso metodológico abrange a análise de algumas estratégias de que se valem os sujeitos para a construção de suas imagens discursivas. O ethos está a serviço de um projeto de influência do Eu sobre o Outro, e pode ser utilizado para atingir seu interlocutor. O enunciador trabalha a adesão do outro pelo alinhamento entre o seu ethos e a imagem do enunciatário.
Saussure, General Linguistics and Grammaticography. Some Reflections On The Early Luso-Hispanic Reception of Saussurean Ideas
Authors: Swiggers Pierre
Published: December 2018

This paper, following up on Bechara’s (2015) pioneering study, is a contribution to the study of the reception of Saussure’s ideas in the field of grammar writing, or grammaticography. After discussing the preliminary conditions for a study of the reception of Saussure’s conceptions, especially as to their relevance for grammar writing, the paper focuses on two cases of early reception in the Luso-Hispanic world. Following Bechara (2015), we first take a look at Manuel Said Ali’s use of Saussurean concepts in his Dificuldades da lingua portugueza (second edition of 1919) and Grammatica historica da lingua portugueza (1921, and second edition, 1931). The second case examined is that of the Catalan author Aragó i Turón, who was the first to present Saussure’s ideas to scholars and intellectuals in Spain. A brief comparative assessment is offered as a conclusion.

Com o objetivo de contribuir para a compreensão da evolução das primeiras edições portuguesas da gramática latina de Manuel Álvares (1526-1583) com o título Emmanvelis Alvari è Societate Iesv de institvtione grammatica libri tres (Lisboa, 1572, 1573) antes e pouco depois da morte do gramático, o presente artigo dedica-se às anotações manuscritas que podem ser encontradas num exemplar eborense da primeira edição da ars maior (Álvares, 1572), no único exemplar da primeira edição da ars minor (Álvares, 1573), bem como em no exemplar pessoal do autor da segunda edição da ars minor, que oferece os paradigmas da conjugação verbal não apenas em latim, mas também no vernáculo castelhano (Álvares, 1578). Da mesma maneira que as anotações nos dois exemplares da ars minor parecem ter tido alguns reflexos nas edições posteriores desta tradição textual, muitas das anotações no exemplar de Álvares (1572) parecem ter entrado na recognitio vellesiana do que seria a última edição da ars maior em Portugal (Álvares / Velez, 1599).
O que se há de entender por gramática: a voz de Bechara e seu tributo a outras vozes
Authors: Moura Neves Maria Helena de
Published: December 2018

Este artigo propõe discutir as obras de Evanildo Bechara como marcadas por duas direções centrais: (i) uma tendência constante de resgatar profundamente (e louvando) os “mestres” que balizam suas posições; (ii) sobre essa base de profundo saber gramatical, uma atenção constante para o que ele determina como a “exemplaridade” em linguagem. A análise se faz em artigos que Bechara publicou na coleção Na ponta de língua (Lucerna, 1998-2005). Conclui-se que, com tal arsenal teórico-metodológico de Filologia e Linguística, esse gramático “tradicional” se define como um ‘cultor’ da língua, sem enquadrar-se porém entre os “guardiães” de um padrão linguístico a ser prescritivamente imposto.
Tensile Deformation Behavior of Ultrasonically Consolidated Laminated Ti-Al Composites at Warm Forming Temperatures
Authors: KAYA İrfan
Published: December 2018

The objective
of the present study is to characterize the mechanical behavior of laminated
metal composites (LMCs) that consist of commercially pure titanium and 1100
aluminum layers which were ultrasonically consolidated.  Ultrasonic consolidation is a low temperature
process used to fabricate layered solid metal structures. Tensile tests of
Ti-Al laminated composites (in 3, 5, and 7 bilayer configurations) were
performed at four various temperatures (25 ºC, 100 ºC, 200 ºC, and 300 ºC)
using strain rate of 0.017 /s. The effect of temperature, sonotrode travel direction,
and number of layers on the material behavior were discussed on the basis of
uniaxial tensile test results. The ultimate tensile strength and yield strength
is found to decrease with increasing temperature. In general, high strain
values were obtained in Y samples compared to X samples. The maximum strain
value was 0.42 at 300 °C temperature in the 5 bilayer Y sample.

RESUMO – Considerando que há relatos de possível intoxicação de milho por causa da dessecação de capim braquiária, o objetivo deste estudo foi determinar o melhor período para semear o milho ‘Yield Gard DKB 390 YC’ após a dessecação da cobertura. O delineamento experimental foi inteiramente casualizado, com quatro repetições. Os tratamentos consistiram em seis períodos de dessecação do capim ruziziensis (25, 20, 15, 10, 05 e 0 dias antes da semeadura do milho) e uma testemunha sem cobertura. As dessecações foram feitas em pleno florescimento do capim ruziziensis com glyphosate a 1,44 kg ha-1. Foram avaliadas as plantas de milho aos 30 e 50 dias após a semeadura (DAS) quanto à altura, área foliar, massa seca de folhas e caule. Aos 150 DAS, foi avaliada a altura de plantas e a inserção da espiga, diâmetro e comprimento da espiga, massa de 100 grãos e produtividade de grãos. A dessecação do capim ruziziensis no mesmo dia da semeadura do milho reduziu a altura das plantas, a altura de inserção da espiga, o diâmetro da espiga e a produtividade de grãos. A melhor época para a semeadura do milho ‘Yield Gard DKB 390 YC’ após a dessecação de capim ruziziensis com glyphosate foi aos 25 dias após a dessecação.Palavras-chaves: Brachiaria ruziziensis, Urochloa ruziziensis, cobertura vegetal, plantio direto, glyphosate. EFFECTS OF DESICCATION PERIODS OF RUZIZIENSIS GRASS ON GROWTH AND YIELD OF MAIZE  ABSTRACT - Considering the possible occurrence of maize intoxication due to the desiccation of ruziziensis grass, the objective of this study was to evaluate the best period for sowing ‘Yield Gard DKB 390 YC’ in the no-tillage system. The experimental design was completely randomized with four replications. The treatments consisted of six periods of desiccation of ruziziensis grass (25, 20, 15, 10, 05 and 0 days before sowing maize) and one control without cover. The desiccations were done at full bloom of the ruziziensis grass with glyphosate at 1.44 kg ha-1. The maize plants were evaluated at 30 and 50 days after sowing (DAS) for height, leaf area, leaf and stem dry biomass. At 150 DAS, plant height and cob insertion, cob diameter and length, 100 grain mass and yield were evaluated. The desiccation of ruziziensis grass in the same day of maize sowing caused reduction in plant height, cob insertion height, cob diameter and yield. The best time for sowing ‘Yield Gard DKB 390 YC’ was 25 days after desiccation of ruziziensis grass with glyphosate.Keywords: Brachiaria ruziziensis, Urochloa ruziziensis, cover crop, no-tillage, glyphosate.

ABSTRACT - Understanding effects of climate variability over agricultural systems may support decisions to improve yield and environmental sustainability. Maize production systems in second season have a significant participation in Brazilian economy, and its yield depends of sowing times and soil water content. This work aimed to study maize yield in four sowing dates and supplementary irrigation in the second growing season in Brazil. The field experiment was developed in the 2015/2016 agricultural year in a completely randomized blocks design. Sowing dates were 01/27/2017, 02/09/2016, 02/25/2016 and 03/11/2016, and two irrigation conditions were adopted: the first without irrigation and the second with a supplementary irrigation of over 130% of the reference evapotranspiration (ET0). Yield performance indicated that the best result was obtained for the 01/27/2017 sowing date. The effects of supplementary irrigation affected the yield for the dates 02/25/2016 and 03/11/2016.Keywords: water balance, productivity, irrigation effect, Zea mays L.  POTENCIAL PRODUTIVO DO MILHO PARA ÉPOCAS DE SEMEADURA EM SEGUNDA SAFRA SUBMETIDO À IRRIGAÇÃO SUPLEMENTAR  RESUMO – O estudo dos efeitos da variabilidade climática na agricultura pode auxiliar nas tomadas de decisão para a melhoria contínua da produtividade e sustentabilidade ambiental. O milho de segunda safra no Brasil tem participação significativa na economia, e sua produtividade está vinculada, entre outros fatores, à pontualidade da semeadura e ao teor de água no solo. O objetivo deste estudo foi avaliar o efeito das épocas de semeadura em segunda safra no desempenho agronômico da cultura do milho em Tangará da Serra-MT, evidenciando a irrigação suplementar para semeaduras antecipadas, indicando a melhor época. O experimento foi realizado no ano agrícola de 2015/2016 com a cultivar de ciclo precoce AG 7088, em quatro épocas de semeadura (27/01/2016; 09/02/2016; 25/02/2016 e 11/03/2016), sob irrigação suplementar a 130% da evapotranspiração de referência (ET0) e sem irrigação, em delineamento experimental de blocos ao acaso com quatro repetições e parcelas de área útil de 7,2 m2. Foram avaliadas as características agronômicas para determinar o desempenho produtivo da cultura, em relação às épocas de semeadura em sistema irrigado e não irrigado. A semeadura realizada em 27/01 apresentou os melhores resultados de produtividade. A irrigação suplementar promoveu efeito sobre a produtividade nas épocas com restrição de chuvas (25/02/2016 e 11/03/2016).Palavras-chave: balanço hídrico, produtividade, efeito da irrigação, Zea mays L.

RESUMO - A colheita, sendo uma das principais etapas no processo produtivo, precisa manter as perdas dentro de um controle aceitável para que seja possível atingir o máximo nível de qualidade e produtividade. No presente estudo, objetivou-se avaliar as perdas quantitativas durante a colheita mecanizada do sorgo forrageiro por meio do controle estatístico de processo (CEP). O experimento foi arranjado em delineamento inteiramente casualizado (DIC), em que foi realizada a análise de variância para a verificação do efeito significativo da declividade e da velocidade operacional nas perdas, e, quando significativos, foi submetida ao teste de comparação de médias de Tukey a 5% de significância. Cartas sequenciais e cartas de controle para valores individuais e de amplitude móveis foram utilizadas como ferramentas de controle estatístico de processo para verificar o efeito da velocidade operacional nas perdas. Com base nos resultados obtidos é possível indicar que a faixa de velocidade operacional de 4 a 5 km h-1 apresentou a menor variação dos dados, não apresentando nenhum ponto fora do limite de controle, o que lhe conferiu a condição de faixa ideal para colheita. Com base na análise estatística houve maiores perdas no transporte à medida que se aumenta a faixa de declividade do terreno.Palavras-chave: colheita mecanizada, forragicultura, carta de controle, velocidade operacional. STATISTICAL PROCESS CONTROL (SPC) APPLIED IN THE MECHANIZED HARVEST OF SORGHUM  ABSTRACT - Harvesting is one of the main steps in the production process and it is necessary to keep the losses under control in order to reach the maximum level of quality and productivity. The present study aimed to evaluate the quantitative losses during the mechanized harvesting of forage sorghum using the statistical process control (SPC). The experiment was arranged in a completely randomized design (DIC), and analysis of variance was performed to verify the significant effect of declivity and operational velocity on losses, and the significant was submitted to the Tukey test at 5% significance. Sequential charts and control charts for individual and mobile amplitude values, composed of upper and lower control and average limits, were used as statistical process control tools to verify the effect of operational speed on losses. Based on the results obtained it is possible to indicate that the operational velocity range from 4 to 5 km h-1 presented the lowest variation of data, presenting no point outside of the control limit, being the ideal range for harvest. The statistical analysis showed higher losses in transportation as the slope of the terrain increased.Keywords: Mechanized harvesting, forage farming, control charts, operational speeds.

Published: December 2018

El artículo trata acerca del contenido del tercer principio de la Declaración sobre la Identidad Cooperativa aprobada por la Alianza Cooperativa Internacional en 1995 tomando en consideración su proceso de elaboración y su relación con los principios incluidos en las anteriores declaraciones de esa organización aprobadas en 1937 y 1966, como así también los comprendidos en los estatutos de la Cooperativa de Rochdale, antecedentes de todas ellas. Se destaca la importancia de este principio como síntesis de los aspectos económicos fundamentales que caracterizan a las cooperativas, analizando las diferentes materias que abarca su enunciado y su relación los demás principios. Se resalta su trascendencia de cara al régimen legal de las cooperativas toda vez que los diversos temas que aborda su amplio enunciado son determinantes para caracterizar a estas entidades y delinear sus rasgos diferenciales con relación a otras formas de organización empresarial. Como conclusión se destaca la complejidad del tema y la necesidad de la adecuada investigación de sus diversas aristas.Recibido: 29 mayo 2018Aceptado: 19 julio 2018Publicación en línea: 21 diciembre 2018
La equidad horizontal en la tributación de las cooperativas en México
Authors: Lara Gómez Graciela
Published: December 2018

La finalidad del artículo fue efectuar un análisis de las cooperativas mexicanas a la luz del principio de equidad tributaria. Se parte de que éstas poseen un tratamiento diferenciado según la Ley del Impuesto Sobre la Renta, por lo que se busca dilucidar los fundamentos jurídicos que apoyan tal circunstancia. Por tanto, se efectuó una aproximación teórica basada en la equidad y su enfoque horizontal, considerando que todas las cooperativas deben ser iguales ante la ley. El método de investigación utilizado fue el exegético, a efecto de ubicar los argumentos que el legislador consideró en la creación de la norma, por lo que además se analizaron las resoluciones de la Corte referidas a la fiscalidad de las cooperativas.Recibido: 25 abril 2018Aceptado: 17 septiembre 2018Publicación en línea: 21 diciembre 2018
