Antropologia & Xenologia
Authors: Valentim Marco Antonio
Published: September 2018

A partir de um comentário à “Anedota das Antilhas” interpretada por Claude Lévi-Strauss em Tristes trópicos, o presente ensaio procurar investigar a relação entre humanidade e estrangeiridade. Para tanto, ele segue dois caminhos. O primeiro, desenvolvendo-se a partir da antropologia lévi-straussiana, tem espaço e tempo como variáveis para as formas daquela relação, em um exercício de antropologia como xenologia humana. O segundo caminho, feito com base na ficção científica de Philip K. Dick, Ursula K. Le Guin, Orson Scott Card e Octavia E. Butler, toma a relação entre humanidade e estrangeiridade segundo espécie e mundo, em um experimento de xenologia como contra-antropologia. A especulação almeja abrir uma passagem entre antropologia e xenologia: mais precisamente, do conceito de humanidade enquanto grau zero da estrangeiridade humana (coespecífica) ao conceito de humanidade enquanto grau zero da estranheza extra-humana (transespecífica).

Published: September 2018

Large amounts of fired ceramic waste produced in ceramic industry do not have a proper method to reuse and mainly thrown away into landfills since fired ceramics have already been sintered and thus their utilization as a raw material is limited. However, these solid wastes have a major environmental and economic concern. Thus, a proper management of such solid wastes is eminent. This research is dedicated to evaluating the possibility of using such ceramic waste as a low-cost filler material in the manufacture of natural rubber based composites. Ceramic particles smaller than 125 μm were selected initially for the preparation natural rubber based composites. For the latter part of the study, particles in sub-micrometer length scales were used. Elemental analyses and composition of the phases of the ceramic particles were determined by X-ray fluorescence and diffraction respectively. The average particle size was characterized by scanning electron microscope (SEM). The surfaces of the sub micrometer size ceramic particles were modified using Silane69 coupling agent. The surface modification was confirmed by Fourier-transform infrared spectroscopy, thermo gravimetric analysis and SEM coupled with energy-dispersive X-ray spectroscopy. Natural rubber based composites were prepared with different levels of ceramic filler loadings. The mechanical properties of the composites such as hardness, resilience, compression set, abrasion volume loss and tensile properties were evaluated. These properties of the composites were compared with those of the composites prepared according to the same formulation except the ceramic filler (control). The composites were found to have an exciting enhancement of mechanical properties with respect to the control. The mechanical property improvement is higher when the ball milled sub-micrometer size ceramic filler is used and it is even better when surface modified ceramic particles are used.

Authors: Sansón Corbo Tomás
Published: September 2018

Walter Alexander de Azevedo (1887-1958) fue un historiador brasileño de escasa repercusión en el demos académico de su país. Existe poca información sobre su vida y producción. Estableció intensos y fluidos contactos con investigadores de Argentina, Uruguay y Paraguay. El objetivo de este artículo es analizar su contribución en el proceso de configuración de los campos historiográficos de la región platense, entre las décadas de 1930 y 1950. Propongo realizarlo en base a un análisis de los vínculos epistolares establecidos con autores como Emilio Ravignani, Ricardo Levene, Alberto Palomeque y Juan Pivel Devoto.
El cooperativismo agrícola del Chaco. Una propuesta para su estudio
Authors: Moglia Leandro Eduardo
Published: September 2018

Los estudios que abordaron la temática del cooperativismo agrícola de primer grado del Chaco, lo hicieron desde diversas perspectivas (histórica-institucional, económica, geográfica, sociológica, etc.), con diferentes objetivos y fuentes; sin embargo todos los trabajos tuvieron en común que sus análisis lo hicieron teniendo en cuenta la evolución política-institucional del Estado-Nación. Metodológicamente, dicha estrategia sirvió para realizar un recorte de las cooperativas de primer grado, pero que no evidenció las dinámicas internas de las instituciones, ni su evolución institucional ligadas a otros factores que modificaron su devenir.Es objetivo de este escrito, generar una propuesta de estudio que parta desde las propias instituciones cooperativas, a partir del análisis institucional y que sirva de modelo para futuras aproximaciones a la temática.
Las movilizaciones estudiantiles en Corrientes y Resistencia durante la "Revolución Argentina", 1966 – 1973
Authors: Millán Mariano Ignacio
Published: September 2018

En el presente artículo analizamos las movilizaciones estudiantiles en Corrientes y Resistencia entre 1966 y 1973, durante la dictadura autoproclamada "Revolución Argentina". Se caracterizan las formas de la acción estudiantil, las corrientes político ideológicas que integran el movimiento estudiantil y se establecen comparaciones con otras experiencias. Para ello se presentan datos cualitativos y cuantitativos sobre las acciones de lucha estudiantil, construidos con información proveniente de los diarios El Territorio, Norte y Litoral, y de una base de datos sobre conflictos estudiantiles. Nuestra contribución consiste en demostrar la importancia de la acción del reformismo universitario y la izquierda marxista durante el período de mayor radicalidad de los movimientos estudiantiles de Argentina, con posterioridad al Cordobazo, un elemento que contribuye a pensar críticamente las hipótesis de uso común sobre la peronización estudiantil y la idea de que la politización de los alumnos dejó en las sombras los problemas netamente universitarios.

Published: September 2018

The degree to which a stock is depleted is one of the most important quantities in fisheries management because it is used to quantify the success of management and to inform management responses. However, stock depletion is extremely difficult to estimate, particularly with limited data. Using the RAM Legacy database, we developed a boosted regression tree (BRT) model to correlate depletion with a range of predictors calculated from catch data, making the model usable for many fisheries worldwide. The most important predictors were found to be catch trends obtained from linear regressions of scaled catch on time, including regression coefficients for the whole catch time series, the subseries before and after the maximum catch, and in recent years. Eight predictors explain about 80% of variation in depletion. There is a correlation of .5 between measured levels of depletion and the predictions of the BRT model. Predictions are less biased when the stock is fished down below half of the carrying capacity. The BRT model outperforms comparable existing catch‐based depletion estimators and could be used to provide priors for depletion for data‐poor stock assessment methods, or used more directly to provide estimates of the probability that depletion is below a given threshold value.
Effect of fishing intensity and selectivity on trophic structure and fishery production
Authors: Zhou Shijie , Smith Anthony D. M.
Published: September 2018

Fishing intensity and selectivity patterns affect ecosystem structure and fisheries yield, the 2 fundamental performance measures in the ecosystem approach to fisheries. We used a simple multispecies predation model to explore the effect of alternative fishing strategies on a 3‑trophic-level food chain. Fishing strategies included highly selective fishing, nonselective fishing, and balanced harvesting that harvests all species at an instantaneous fishing mortality rate either proportional to intrinsic population growth rate or proportional to current population growth rate. The results showed that harvesting species at higher trophic levels has a low impact on total biomass but results in very low yields and severe impacts on trophic structure. Selectively harvesting species at the bottom of the food chain reduces the biomass of all fish, results in high yields, and is the only strategy that maintains unfished trophic structure. Non-selective fishing produces high total yield, but can cause extinction of fish at high trophic levels, and severely alters the trophic structure. Balanced harvest strategies produce higher total yield than harvesting species only at the bottom of the food chain, and have a smaller impact on trophic structure than selectively harvesting the top predator or nonselective fishing, but cannot fully maintain trophic structure. While these findings from a very simple model can provide insight into results from more complex models, analysis of sensitivity to structural assumptions in such simple models will be required to shed further light on the dynamic consequences of fishing across multiple trophic levels.
Priming is swell, but it's far from simple
Authors: Ziegler Jayden , Snedeker Jesse , Wittenberg Eva
Published: September 2018

Clearly, structural priming is a valuable tool for probing linguistic representation. But we don’t think that the existing results provide strong support for B&P’s model, largely because the priming effects are more confusing and diverse than their theory would suggest. Fortunately, there are a number of other experimental tools available, and linguists are increasingly making use of them.
Bayesian Estimation for Gaussian Graphical Models: Structure Learning, Predictability, and Network Comparisons
Authors: Williams Donald Ray
Published: September 2018

Gaussian graphical models (GGM; ``networks'') allow for estimating conditional independence structures that are encoded by partial correlations. This is accomplished by identifying non-zero relations in the inverse of the covariance matrix. In psychology the default estimation method uses $\ell_1$-regularization, where the accompanying inferences are restricted to frequentist objectives. Bayesian methods remain relatively uncommon in practice and methodological literatures.To date, they have not yet been used for estimation and inference in the psychological network literature. In this work, I introduce Bayesian methodology that is specifically designed for the most common psychological applications. The graphical structure is determined with posterior probabilities, which allow for assessing conditional dependent and independent relations. Additional methods are provided for extending inference to specific aspects within- and between-networks, including partial correlation differences and Bayesian methodology to quantify network predictability. I first demonstrate that the decision rule based on posterior probabilities can be calibrated to the desired level of specificity. The proposed techniques are then demonstrated in several illustrative examples. The methods have been implemented in the R package BGGM.
Politeia’s place in our practical life: Pierre Bourdieu on the modern state
Authors: Mullender Richard
Published: September 2018

Pierre Bourdieu’s account of the modern state’s emergence has affinities with the analyses of legal systems offered by Herbert Hart and Hans Kelsen. Bourdieu, Hart, and Kelsen each describe normative spaces within which practical life unfolds. While Bourdieu’s account of the state as ‘a space of spaces’ is less systematic than the analyses of Hart and Kelsen, he augments their contributions in important ways. He conveys a more definite sense of the texture of lived experience within the space he describes than either Hart or Kelsen on the modern state. Bourdieu’s analysis also affords a basis on which to draw out the significance of institutions that rarely feature in jurisprudential works on the state or legal systems. This article illustrates this point by reference to the public inquiry. It also finds at work within On the State an ideal that gives expression to an egalitarian philosophy of government. This is the ideal of politeia, which, on the view offered here, identifies legal, political, and economic institutions and practices as constituents of ‘community.’

Published: September 2018

The population of geriatric animals has grown considerably in the last years, consequently, the number of visits in the veterinary clinical routine of these animals also showed a strong increase. As a useful tool in the diagnosis of diseases or even for the monitoring of animal health, blood tests are aimed at identifying changes that may be a reflection of some pathological process. Within the blood analyzes, the biochemical profile, if correctly interpreted, gives references regarding the clinical state of an animal, as well as its nutritional balance, immunological status, follow-up of treatments and prognoses. Due to the importance of biochemical parameters in the diagnosis of diseases, especially in the geriatric population, the objective of this study was to evaluate the occurrence of alterations in biochemical tests that indicate changes in the renal and hepatic functions of elderly dogs and to classify them in relation to gender and age. For this, biochemical exams were collected in two laboratories in the city and the age of the animals was screened, followed by screenings for liver and kidney alterations and another for sex. The most frequent alteration in the population of geriatric and senior dogs was Alkaline Phosphatase with 50.8% (2.206 / 4.341) and 41.6% (979 / 2.352), respectively. The second analyte with the highest frequency of changes was Urea with 44.2% (1,923 / 4,341) in geriatric dogs and 29.9% (705 / 2.352) in senior dogs. The relevance of sex in relation to age was significant in Alkaline Phosphatase and Urea markers.

Published: September 2018

Coccidiosis is one of the main diseases of the gastrointestinal tract of ruminants, manifested by subtle changes such as reduction of weight gain, watery diarrhea until bloody diarrhea. In its clinical form, the intestinal mucosa compromises the absorption of nutrients from the diet, culminating in delays in the clinical recovery of the animals. The present work aimed to evaluate the efficacy of two treatments in the clinical recovery of coccidiosis in growing dairy calves by evaluating hematocrit, protein and fibrinogen plasmatic, leucogram, egg count per gram of feces, visual inspection of the pelage and incidence of diarrhea. Seven Jersey calves between 2 and 6 months of age with coccidiosis were divided into two groups according to the treatment. The antibiotic and catofos group (C), with four calves, was treated with sulfamethoxazole + trimethoprim and the immunostimulant butafosfan + vitamin B12 (Catofós®), both in a single dose, and the antibiotic group (A) with three calves was treated with only sulfamethoxazole + trimethoprim in a single dose. It was observed that both treatments were effective in combating the disease, reducing the symptomatology of the disease, improving the pelage of the animals and negatively coproparasitological examination. Although the parameters leukogram, fibrinogen and protein plasmatic did not change with the treatments, the antibiotic and catofos group had a significant increase in the hematocrit, allowing to prove the efficiency of both drugs.

Calling as a Motivating Factor of the Development of Education in Ukraine
Authors: Muliarchuk Yevhen Ivanovych
Published: September 2018

The article raises importance of the topic of mission in contemporary philosophy and educational sciences. Mission is a basic idea for building up of civil society as a community of responsible and committed people. Mission has a special significance for teaching professions. Ukraine as well as many other countries experiences a shortage of teachers. Many successful students of pedagogical professions prefer to get other jobs because of low salaries and prestige of teaching. The problem of motivation in educational sphere needs political, public and scientific awareness.

The skeptics and pragmatics are not sure that mission is a vital idea of our days. That is why it was important to find out whether the phenomenon of mission exists in the consciousness of contemporary Ukrainians and how it appears to them. In the focus of the article are opinions of secondary school graduates, students, whose area is educational sciences and professional teachers. The method and strategy of the presented research is hermeneutic phenomenology. The relevant experience of people was examined and interpreted by in-depth interviews. Before in-depth interviews there was conducted a quantitative survey which provided the statistical data about the choosing factors of future professions and the share of those who declare having the experience of mission.

The result of the survey is that at least half of Ukrainian youth think that the idea of mission is important for their choice of profession. Mission as a phenomenon shows the unity of structural elements: Desire – Talent – Realization – Social or Spiritual Benefit. The aim of transpersonal goodness is the core of the phenomenon of mission and the integrity of its structure. Teaching as a career definitely needs mission, even though it is not true for some teachers. That is undoubted thesis for Ukrainians. Teacher’s mission is to bring young people to their own missions. If the essence of education is a rising people to the level of spirit out of the level of matter, the task of a teacher is to bring up that ability of that rising in the youth. People of mission are those who have to be in the center of the development of education system reforms in Ukraine.

The article analyzes the factors that have a significant influence on the truth (in the Aristotelian sense) of a biographical and autobiographical narrative. Restrictions emerging from the possibility of correct “reading” of the phenomena of our inner life and limitations associated with the so-called Experienced judgments are demonstrated. Biography could not avoid bio-socio-cultural conditions, as well as sphere of emotions, whose attributes can largely falsify reality, as well as its interpretation.
Gregory Skovoroda’s Philosophy of Education: the Difference of a Modern Vision
Authors: Gomilko Olga
Published: September 2018

The article is devoted to the analysis of the modern character of the Gregory Skovoroda’s philosophy of education. Unlike his contemporaries, he focuses on connections of philosophy and moral virtue. This position contradicts the tendency of a modern institutionalization of philosophy in the way of one more discipline of the modern research university. However, Skovoroda’s critical position does not put into question the modern content of his philosophy. On the contrary, Skovoroda’s understanding of philosophy reveals the salvific ways of its cognitive and practical rehabilitation. It is because his philosophy teaches people to be wise not only the university campus but in all spheres of their own lives. That is why he speaks not just of philosophy, but of the “philosophy of the heart”. Contrary to Christian thought, he believes that human’s transformation is possible not through faith and suffering, but through the discovery a “new body” on the ground of self-knowledge and love for oneself. Unlike the modern classical philosophy, Skovoroda considers self-knowledge, not as a function of mind alone, and the heart as a dichotomy to the mind. In accordance with contemporary educational theories based on the idea of anthropotechnical turn in philosophy, Skovoroda deems the heart an instrument for enhancing the mind. Involving the heart into the sphere of rational increases the thinking of knowledge about the specific situation of its embodiment and the cognitive capabilities of its carrier. According to Skovoroda, an important consequence of such human transformations should be the overcoming of fear and hatred of the “other”.
Experience of Mastering of Critical Thinking in the Ukrainian Higher Education
Authors: Tiaglo Oleksandr
Published: September 2018

It is argued in this paper that demands for critical thinking (CT) will be determined by needs both of political superstructure and productive forces of a competitive society in the 21st century. Phenomenon of CT has to be studied and understood as one of the essential elements of some more complex entities – higher-order thinking, core of work-related skills, etc. CT skill need to be developed in connection with relevant cognitive and affective dispositions. It is pointed out, therefore, that it is more correct not to be limited by teaching CT but to educate a critical thinker, whose CT skill is relied on base of relevant dispositions. The process of educating a critical thinker, or rather – a person who will have CT, for instance, as element of a set of the core work-related skills, should continue during the kindergarten, school and university education at least. It is substantiated that under conditions of Ukrainian higher education it is expediently to use two interconnected courses in the process of CT education: logic with elements of critical thinking – in frame of the bachelor’s degree studies – and critical thinking on base of logic – in frame of the master’s degree studies.

The book of world-known German philosopher Jurgen Habermas is devoted to the Marxist social theory and in general to potential of the evolutionary concept of society. A wide range of topics is comprised: from the role of philosophy inMarxism and rational and ethical foundations of social identity to comparative theories and problem of legitimacy. J.Habermas does not only critically rethink Marxist concept, but builds a coherent theoretical alternative to it. The power of the book is that the key problems of social theory are considered not only in the abstract plane but in the context of contemporary, keen, topical socio-political challenges. Namely the nature of current social crises, conflicts of legitimation ofthe contemporary state, the morality of power, the effect of innovations etc. The book has become not only one of the classical samples of Marxism analysis, but it was recognized significant contribution to contemporary social theory.
Exposure to antiresorptive therapy with bisphosphonates does not induce histological changes in human alveolar jawbone
Authors: Bedogni Alberto , Bettini Giordana , Bedogni Giorgio , Abbasi Nooshin , Saia Giorgia , Blandamura Stella
Published: September 2018

Aim: The identification of specific alterations in the alveolar jawbone of patients treated with nitrogen-containing bisphosphonates (NBP) but without bisphosphonate-related osteonecrosis of the jaw (BRONJ) may help to identify the early steps of BRONJ and to select patients at risk for it.
Materials and Methods: We performed a case-control study. Cases were 60 individuals treated with NBP without clinical and radiological signs of BRONJ and requiring surgical tooth extraction. Controls were 60 individuals never treated with NBP and requiring tooth extraction. Cases and controls were matched by sex (same) and age (within 5 years). 18 categorical (basophile reversal lines, osteoblasts, osteoblastic lines, osteocytes, empty osteocytic lacunae, osteoclasts, Howship’s lacunae, vessel dilatation, vascular congestion, arteriolar thickening, intravascular fat globules, calcific fat necrosis, fatty bone marrow, ruptured adipocytes, granular cytoplasm of adipocytes, oil cysts, perivascular fibrosis, diffuse fibrous metaplasia) and 2 ordinal histopathological variables (inflammation and bone maturation) were investigated. Exact univariable and multivariable (correction for gender and age) logistic regression was used to test the association between NBP use and the histopathological variables. Because of multiple comparisons, the critical p-value was set to 0.0025 (0.05/20).
Results: Cases and controls did not differ for any study variable except for vascular congestion that was significantly associated with NBP use (multivariable OR = 0.24, exact 95% CI 0.10 to 0.57 for cases vs. controls, p = 0.0006).
Conclusions: Use of NBP does not produce specific histological alveolar bone alterations in the absence of overt BRONJ disease.

O nematoide Pratylenchus brachyurus tem se destacado como a espécie de nematoide fitoparasita mais frequente em áreas de produção agrícola do Brasil-Central. A reação de espécies vegetais ao nematoide tem sido pouco estudada. Por essa razão, foram realizados dois experimentos em casa de vegetação, com o objetivo de caracterizar a reação de cinco espécies vegetais de interesse econômico (soja, algodoeiro, milho, capim-marandú e capim-mombaça) à presença de P. brachyurus. Cada espécie foi inoculada com zero, 333, 1.000, 3.000 e 9.000 nematoides/planta no primeiro experimento e zero, 1.500, 4.500, 13.500 e 40.500 nematoides/planta no segundo experimento. Sessenta dias após a inoculação, foram realizadas avaliações morfo-fisiológicas das espécies vegetais (altura de planta, teor de clorofila e taxa fotossintética) e aos 90 dias após a inoculação avaliou-se a massa fresca do sistema radicular, a massa seca total da parte aérea, o número de lesões no sistema radicular, determinando o número de ovos/g de raiz e o fator de reprodução do nematoide. O nematoide causou danos primários, caracterizados por lesões radiculares em todas as espécies, mas com maior intensidade na soja. No entanto, independente da densidade populacional, não se verificou danos na parte aérea. A multiplicação do nematoide, expressa pelo fator de reprodução (FR) foi maior na menor densidade populacional, em ambos os experimentos. Milho e soja são as espécies que permitem a maior multiplicação de P. brachyurus em suas raízes. Palavras-chave: Cerrado, polpa de fruta, despolpamento, frutos tropicais.

Potato (Solanum tuberosum L.) is a major crop worldwide and the tuber yield of currently used cultivars is strongly reduced at high soil salt levels. The effects of salt stress on early sprout growth of potato plants were investigated using the cultivar Ágata. Potato seed minitubers were planted in 0.4 L pots filled with commercial substrate (Bioplant®), and maintained under greenhouse conditions. A completely randomized design with five treatments and five replications was used. Three days after sprouting, potato plants were exposed to five salinity levels [0 (control), 25, 50, 75 and 100 mmol L–1 of NaCl] for 28 days. Results showed that the exposure of plants to 100 mmol L–1 NaCl reduced the shoot height (72%), shoot dry matter (76%) and root dry matter (75%) of potato plants compared to the NaCl-free control. The length of longest roots was not affected by salinity levels, indicating that inhibition of shoot growth is more severe that of the root. The exposure to high salt concentrations severely restricted the early sprout growth of potato plants. Results of this study stated that salt-stress is a constraint on potato production, and the use of cultivars tolerant to salt stress can be a strategy to achieve high levels of potato tuber yield under salinity conditions.

O nitrogênio (N) é o nutriente mais limitante à produtividade do milho, sendo requerido em grandes quantidades para suprir a demanda da cultura. Além disso, o N aplicado via fertilizante mineral é muito susceptível a perdas por volatilização e/ou lixiviação, o que sugere a necessidade de estudos sobre métodos de aplicação visando otimizar o uso deste insumo. Objetivou-se com este estudo avaliar os efeitos de métodos de aplicação de N na cultura do milho nas condições do Cerrado Mato-grossense. Foram testadas duas formas de aplicação do N, na forma de ureia: aplicação a lanço em área total e incorporação ao solo na linha de plantio as quais foram parceladas em duas aplicações (semeadura e estádio vegetativo V6). O delineamento experimental utilizado foi o de blocos casualizados com três tratamentos e sete repetições. No estádio do pleno florescimento masculino assim como em R2, R3 e R6 observou-se, entre os tratamentos, diferença na altura das plantas, diâmetro de colmo, peso de matéria fresca e seca da parte aérea. Por outro lado, a leitura do teor de clorofila na folha não foi alterada pelo método de aplicação de N. A maior produtividade e peso de matéria seca de grãos foi obtida com a incorporação do N ao solo. Os resultados obtidos neste estudo sugerem que a aplicação de N de forma incorporada ao solo é a melhor estratégia para a obtenção de altas produtividades de grãos de milho para as condições do estado do Mato Grosso.

O presente estudo busca, evidenciar o reaproveitamento do resíduo agroindustrial bagaço de malte, na fabricação de pigmentos naturais produzidos por Monascus, determinando a velocidade de crescimento radial pelo fungo filamentoso Monascus ruber CCT 3802, em cultivo sólido sob diferentes concentrações de bagaço de malte. A determinação da velocidade de crescimento radial foi realizada em meio ágar dextrose batata (PDA) sob diferentes concentrações de substrato bagaço de malte (5, 10, 20 e 40 g.L-1), além da placa padrão contendo apenas PDA. A maior velocidade de crescimento radial do Monascus. ruber foi obtida da placa contendo 40 g.L-1 de bagaço de malte 0,1383 mm h-1, o que corresponde a um crescimento de 3,32 mm dia-1, ou seja, um aumento de 54,95% quando comparado com meio PDA, mostrando que quanto maior a concentração de bagaço de malte, maior a velocidade de crescimento radial, consequentemente maior a produção de pigmentos. O bagaço de malte apresentou influência direta nos resultados da velocidade de crescimento radial do micro-organismo Monascus ruber. Portanto pode-se utilizar o resíduo bagaço de malte como substrato em cultivo sólido para a obtenção dos pigmentos de Monascus ruber.

Apesar do acréscimo na produção nos últimos anos, atualmente ainda são escassos os produtos no mercado destinados à indivíduos com restrições alimentares. O presente estudo visou desenvolver “muffins” (bolinhos) isentos de glúten e lactose, utilizando farinha de arroz e resíduo da filtragem da polpa de graviola (Annona muricata), e avaliar a influencia do resíduo nas características da massa. Os muffins elaborados com 0 % (padrão), 10, 20 e 30 % de resíduo da polpa de graviola em substituição a farinha de arroz, foram submetidos a análises físicas de peso, diâmetro e espessura antes e depois do forneamento, cálculo da expansão de massa, análise de pH, cinzas e umidade. Valores obtidos nas análises físicas dos muffins demostraram que as amostras com maior adição do resíduo (30%), obtiveram maior diâmetro, crescimento da massa (espessura), e coloração mais escura. Os valores de pH e umidade para o muffin também variaram em relação à concentração do resíduo, e os valores para cinzas não demonstraram diferença significativa em relação à adição. A partir dos resultados obtidos foi possível observar que o aumento nos níveis de adição de resíduo de polpa de graviola influenciou as características da massa dos muffins desenvolvidos.

A compactação do solo determina, de certa maneira, as relações entre ar, água e temperatura, e estas influenciam praticamente em todas as fases do desenvolvimento vegetal. Nesse sentido, o objetivo do trabalho foi avaliar o efeito de diferentes profundidades de compactação, no desenvolvimento da cultura do milho. O delineamento experimental utilizado foi o de blocos inteiramente casualizados, com cinco tratamentos (0, 25, 50, 75 e 100% de compactação) e quatro repetições totalizando 20 unidades experimentais. Essas unidades experimentais foram representadas por vasos de polipropileno com 18 cm de altura e volume de 6,7 dm3. As características avaliadas foram: Altura de plantas, massa verde da parte aérea, massa seca da parte aérea, massa verde de raízes compactadas, massa seca de raízes compactadas, massa verde de raízes sem compactação, massa seca de raízes sem compactação. Os resultados evidenciaram que tanto o crescimento da parte aérea como o crescimento das raízes de milho são prejudicados pela compactação do solo.

Published: September 2018

O objetivo do trabalho foi estudar a equivalência de tempos de secagem para determinação de umidade do solo em forno micro-ondas comparada ao método padrão (estufa). Tal estudo foi realizado em um Latossolo Vermelho-Amarelo de Cerrado nas classes texturais de 20, 35 e 50% de argila. As amostras de solo foram submetidas a cinco tempos de secagem no micro-ondas (2; 4; 6; 8 e 10 minutos) em comparação com o método padrão (110 ºC/24 h), em um experimento inteiramente casualizado. As análises de regressão dos dados quantitativos apresentaram altos coeficientes de determinação, demonstrando a possibilidade do uso do micro-ondas na determinação da umidade do solo (%) pela rapidez e confiabilidade de resultados em relação ao padrão de estufa.

Orelha-de-rato (Dichondra repens – Convolvulaceae) é uma planta perene de baixo crescimento, considerada como forrageira. O trabalho teve como objetivo a identificação da ferrugem da orelha-de-rato causada por Puccinia sp. Amostras de folhas de orelha-de-rato foram coletadas no município de Bento Gonçalves, RS, exsicatadas e depositadas na coleção micológica de referência do IF Goiano Câmpus Urutaí e, posteriormente, analisadas em microscópio estereoscópico. Lâminas semi-permanentes e cortes histológicos foram realizados. Para registro dos sintomas e sinais do patógeno fez-se macro e microfotografias. A morfometria das estruturas reprodutivas foi realizada utilizando microscópio óptico. O fitopatógeno apresentou télia de coloração marrom avermelhado, hipófila e subepidérmica encontrada na face abaxial da folha, com dimensões 180-260 x 210-340 µm. Teliósporos lisos, bicelulares, com dimensões de 32,1 - (27,1) - 22,2 x 19,4 - (14,8) - 11,3 µm de coloração pardo a marrom avermelhado com papila de comprimento 7,5 - (5,0) - 2,6 µm, hialina e pedicelos filiformes e hialinos, com comprimento de 24,7 - (12,6) - 6,7 µm. Inicialmente os teliósporos jovens apresentaram-se hialinos e quando maduros se tornaram melanizados. Com base nas características descritivas da fase telial o isolado oriundo de Bento Gonçalves, RS, (2011) foi identificado como Puccinia dichondrae.
