Published: July 2019

As a kind of transcription factors gene family, MADS-box genes play an important role in plant development processes. To find genes involved in the floral transition of Ginkgo biloba, a MADS-box gene, designated as GbMADS2, was cloned from G. biloba based on EST sequences by RT-PCR. Sequence analysis results showed that the cDNA sequence of GbMADS2 contained a 663 bp length ORF encoding 221 amino acids protein, which displayed typical structure of plant MADS-box protein including MADS, I, and K domains and C terminus. The sequence of GbMADS2 protein was highly homologous to those of MADS-box proteins from other plant species with the highest homologous to AGAMOUS (CyAG) from Cycas revoluta. The phylogenetic tree analysis revealed that GbMADS2 belonged to AGAMOUS clade genes. Real-time PCR analysis indicated that expression levels of GbMADS2 gene in female and male flower were significantly higher than those in root, stem, and leaves, and that GbMADS2 expression level increased along with time of flower development. The spatial and time-course expression profile of GbMADS2 implied that GbMADS2 might be involved in development of reproductive organs. The isolation and expression analysis of GbMADS2 provided basis for further studying the molecular mechanism of flower development in G. biloba.

Published: July 2019

A total of 38 eggplant genotypes, of which 32 were heirloom accessions collected from different regions of Burdur province five were different local genotypes from other provinces, and one was a cultivar, were used as reference in this study. The phylogenetic relationships among these heirlooms were evaluated using 40 morphologic descriptors and five randomly amplified polymorphic RAPD markers. The horizontal dendrograms were created by using UPGMA with both morphologic and molecular data. Burdur heirloom accessions showed high genetic diversity based on morphological and molecular data. The genetic similarity rates ranged from 0.29 to 0.91 according to the morphological data, and ranged from 0.84 to 0.98 according to the molecular data. Molecular data generated by RAPD method, compared to morphological data, were insufficient to reveal genetic diversity. Therefore, in order to confirm genetic variations, studies based on other molecular methods are necessary. The regional genetic populations include a wide eggplant genetic diversity which can be good source for the breeding studies performed in the future.

The probiotic properties and the viability of lactic acid bacteria of fermented dairy products can be improved by addition of bioactive compounds originating from natural sources (e.g. goji berries). This study aimed to evaluate how goji berries and honey affect the sensorial quality of yoghurt, the chemical properties, the viability of lactic acid bacteria (LAB) and the concurrent microflora development. Two types of yoghurts (yoghurt with goji berries and yoghurt with honey and goji berries) were developed. The addition of honey affected the entire yoghurt microflora including LAB, manifesting bactericidal effect. The addition of goji berries maintained the viability of LAB at probiotic levels (106-107 log CFU/ml) during 21 days of storage; compared to classic yoghurt, LAB viability decreased during storage at 103 log CFU/ml. Goji berries also improved sensory acceptance of consumers. The results obtained in this study collect information that enables the use of goji berries as enhancer of probiotic levels in yoghurt, while honey can provide bacteriostatic/bactericidal effect for contaminants.
Effect of Planting Systems and Growing Media on Earliness, Yield and Quality of Strawberry Cultivation under Soilless Culture
Authors: ADAK Nafiye , GUBBUK Hamide
Published: July 2019

Soilless growing is becoming an attractive option because of the contamination of agricultural land due to the use of excessive fertilisers and insecticides to get higher productivity per unit area and the yield advantage with soilless culture getting more yield per unit area than the conventional growing.  Effects of two planting systems and various growing media on earliness, yield and quality (colour L, C, ho, the rupture of calyx, firmness, total soluble solid, acidity and vitamin C) in strawberry (Fragaria Ã— ananassa Duch.) cultivation under soilless culture was studied. Two different planting seasons i.e., summer and fall were chosen and growing media was composed of peat (Pt), perlite (Pr), cocopeat (Co), volcanic tuff (Vlc) and their combinations. Results showed that fall planting system was favourable in terms of earliness but summer planting gave better results in terms of total yield. Moreover, the first harvest of summer planting was February, whereas the first harvest of the fall planting was in December. Early yield in the fall planting comprised 36.0% of the total yield. The Co and the Co+Vlc media were more favourable than other media with regard to yield, earliness and fruit quality. In addition vegetation period was found from January to May and it was observed that as the total soluble solids values increased in fruits, acidity and vitamin C values decreased.
Effects of Different Priming Treatments on Seed Germination Properties, Yield Components and Grain Yield of Lentil (Lens culinaris Medik.)
Authors: TOKLU Faruk
Published: July 2019

An experiment was conducted under laboratory and field conditions in order to evaluate the effects of different priming treatments, specifically KNO3 (1%), KCl (2%), KH2PO4 (1%), ZnSO4 (0.05%), PEG-6000 (20%), IBA (100 ppm), Mannitol (4%), GA3 (100 ppm) and distilled water, on seed germination properties and several agro-morphological plant characteristics of red lentil. Seeds not primed were used as a control. GA3 treatment increased shoot length. The control (non-primed seeds) treatment resulted in increased seedling root number and length. Distilled water, ZnSO4 and control treatments increased germination rate and percentage. In the pot experiments, GA3 treatment increased plant height and seedling emergence rate, whereas KCl treatment improved the number of nodules, as well as root and shoot dry weight when compared to the control. ZnSO4 treatment increased yield components and grain yield in field conditions. The results of this study showed that ZnSO4, GA3 and PEG-6000 seed priming treatments may be useful tools due to their positive effects on germination rate, germination percentage, yield component and grain yield of lentil.

Bread wheat (Triticum aestivum) is the most commonly grown crop due to its adaptation in a wide range of eco-geographical conditions and providing enhanced food assurance to the modern world. A diverse and rich collection is the foundation of each successful wheat improvement program. Therefore, major efforts are in progress worldwide to boost wheat production by broadening genetic diversity. Accepting this issue as a target, present study gives an overview of the major progress in the diversity and population evaluation of Indian and Turkish hexaploid wheat employing ISSR and RAPD primers. Various statistical analyses were employed for determining the hexaploid wheat population structure of India and Turkey. Results of dendrogram, scatterplots, Analysis of Molecular Variance (AMOVA) and population structure analysis were found in accordance with each other. All the experimental genotypes were clustered in two main groups, one group containing Indian varieties and another group containing both Indian and Turkish varieties reflecting the direct or indirect interbreeding among the populations of the two countries. Utilizing the genetic association of Indian and Turkish hexaploid wheat population, based on genetic distance estimated in the study, researchers worldwide may include Indian and Turkish hexaploid varieties in the wheat improvement programs and can evade the likelihood of selected germplasm becoming hereditarily consistent.

Published: July 2019

Forested land in the world is about 28% of the global land area, accounting for 80% of the terrestrial carbon stored as biomass and soil organic carbon. Human activities, namely fossil fuel combustion and deforestation resulted in anthropogenic emissions into the atmosphere. Deforestation is being focused in this study in view of the role of forests as carbon stocks. Carbon is normally referred to as biomass of the tree. Several studies revealed that carbon is mostly sequestered in the aboveground part of biomass. As Southeast Asia has the highest level of deforestation, this study focused on observing carbon stocks in Malaysian forests. The conducted estimation of forest carbon stocks reveals carbon stock increment owing to the increment in the forested land. Yet, the forest transition process necessary for expanding the areas of forested land appears to be difficult to achieve. The economic development in the agricultural sector, land conversion for industrialization and settlement, expansion of wood-based industry and employment opportunities in the wood-based sector may hamper forest transition.

Published: July 2019

Accurate assessment of crop-weed control period is an essential part for planning an effective weed management for cropping systems. Field experiments were conducted during the seasonal growing periods of potato in 2012 and 2013 in Kayseri, Turkey to assess critical period for weed control (CPWC) in potato. A four parameter log-logistic model was used to assist in monitoring and analysing two sets of related, relative crop yield. Data was obtained during the periods of increased weed interference and as a comparison, during weed-free periods. In both years, the relative yield of potato decreased with a longer period of weed-interference whereas increased with increasing length of weed free period. In 2012, the CPWC ranged from 112 to 1014 GDD (Growing Degree Days) which corresponded to 8 to 66 days after crop emergence (DAE) and between 135-958 GDD (10 to 63 DAE) in the following year based on a 5% acceptable yield loss. Weed-free conditions needed to be established as early as the first week after crop emergence and maintained as late as ten weeks after crop emergence to avoid more than 5% yield loss in the potato. The results suggest that CPWC could well assist potato producers to significantly reduce the expense of their weed management programs as well as improving its efficacy.

Published: July 2019

In plants cultivation, some species influencing each other in a favorable manner, and others adversely affect the result of the release of physiologically active substances. These substances, called allelopathic compounds are excreted primarily by underground and aboveground plants’ organs or formed during the decomposition of their remains. Allelopathins show the inhibitory or stimulating effects on the processes of seed germination, growth and physiological activity of plants. The aim of the study was to determine the allelopathic effects of aqueous extracts from the peppermint (Mentha × piperita L.) leaves at various concentrations (1, 3, 5, 10, 15%) on seeds germination and the selected physiological processes of common sunflower (Helianthus  annuus L.) seedlings. Seeds were germinated and plants were grown under greenhouse conditions for 30 days. Germination of sunflower seeds was reduced and electrolyte leakage from seedlings increased with increasing concentrations of aqueous extracts of the peppermint leaves. Increasing concentrations of aqueous extracts of peppermint also caused decrease of chlorophyll a and an increase of chlorophyll b content. The highest increase of the maximum photochemical efficiency of photosystem II was observed in H. annuus L. treated with 15% peppermint extract in comparison to the lower concentration of extracts  and to the control. Non-photochemical and photochemical quenching and vitality index of hotosystem II decreased with increasing concentrations of allelopathic substances in peppermint extracts.

Published: July 2019

The objective of this study was to examine the combined effects of selenium (Se) enrichment and water stress on the accumulation of available macro- and micronutrients in Melilotus officinalis L. aerial parts. Plants of M. officinalis were subjected to three levels of Se addition (0, 1 and 3 mg Se L-1 water) and to two water treatments: a) full irrigation and b) limited irrigation (water stress). The above ground biomass (stems and leaves) was analyzed for Se, potassium (K), sodium (Na), magnesium (Mg), iron (Fe), copper (Cu), calcium (Ca), manganese (Mn) and zinc (Zn). Se addition differentially affected the K, Mg and Ca content of M. officinalis aerial parts, while it led to the reduction of the micronutrients Cu, Fe and Mn. Water stress resulted in the increase of K, Na, Mg, Ca and Cu, and to the decrease of the Fe, Zn and Mn content. An interaction between selenium addition and water treatment was more notable for Ca and Mg, which decreased under water stress at low Se level and for Zn and Cu, which increased under water stress at high Se level. According to our findings, Se-induced increased accumulation of some inorganic ions in the aerial parts of this species under water stress conditions could serve as a means to alleviate the adverse impact of water deficit on important metabolic processes, enhancing M. officinalis tolerance to water stress.

Published: July 2019

In Tunisia, Opuntia ficus-indica (L.) Mill., occupying many hundreds of thousand hectares, constitutes a future plant as a fruit tree, mainly due to its edible fruit and vegetal mass used as food. The continuously increasing demand for young plants for the extension of its cultivation requires the research of rapid, efficiency and economic methods ensuring conformity multiplication. With aim to a large production of plant material, a rapid in situ propagation method of the prickly pear cactus was developed. Varied portions of Opuntia ficus-indica cladodes harvested in spring or in autumn, planted horizontally or vertically were used in order to optimize rhizogenesis and secondary cladode initiation rates. Half, quarter and the tenth of cladode cuttings harvested and planted in spring vertically and in normal polarity show very interesting results concerning rhizogenesis and caulogenesis. Those portions of cladodes demonstrated the best results, vertically planted in normal polarity and 100% of rooting was observed on right ones. The number of roots was the highest on basal right tenth cuttings (80). Contrariwise, the percentage of secondary cladodes initiated was the highest on apical right cuttings (70 and 74%) and the longest roots were initiated on the two basal tenth cuttings, left and right ones (13 and 14 cm). This fragmentation represents a substantially gain of material and time especially for large cultivated surfaces of Opuntia ficus-indica. Reducing the cladode cutting size, do not reduce its rhizogenesis and caulogenesis potentialities.

Published: July 2019

Seeds of the genus Lolium are difficult to identify based on morphology for morphological likeness and some physical deformation such as friction and flattening during storage and transport. DNA barcoding, a newly-established method, has been used to discriminate a variety of agricultural crops with its own advantages. In present study, DNA barcodes for the genus Lolium were investigated for the first time. DNA sequences of psbA-trnH, rbcL, atpF-atpH, and the ITS2 region were evaluated for their ability to differentiate Lolium from the related genus Festuca. As confirmed by inter-intraspecific divergence and Kimura 2 parameter analysis, the greatest divergence existed in ITS2, followed by psbA-trnH. On the contrary, rbcL and atpF-atpH possessed poor genetic variation of 0-0.0115, and was relatively difficult in discrimination of genus Lolium. For ITS2 sequence, no inter-intraspecific distance overlaps were observed and each species has a distinct barcoding gap. ITS2 could effectively discriminate all species based on a neighbor-joining tree. Thus, the ITS2 region is a candidate for DNA barcoding of Lolium.

Published: July 2019

Salinity is an important restrictive factor for plant growth and ecosystem productivity. However, the endogenous mechanisms by which salinity constrains plant growth are not well understood. To determine the mechanism by which soil salinity suppresses plant growth under salt stress, the effect of soil salinity on hormones in the leaves of Leymus chinensis and the plant density, height and biomass were examined in Songnen meadow steppe. The plants with rhizosphere soil were collected in the growing season (May, June, July, September, October) from the field at different salt levels. The shoot density, height and biomass accumulation of L. chinensis highly decreased with the increase in the soil salinity. Salinity significantly reduced the synthesis of the hormones gibberellic acid (GA3) and indoleacetic acid (IAA), but it increased the concentration of abscisic acid (ABA). Significant negative correlations between the soil electrical conductivity and plant leaf hormones (GA3, r = -0.853, P < 0.05; IAA r = -0.971; P<0.01) related to plant growth and positive correlation with ABA (r = 0.931, P<0.01) were observed. Significant positive correlations between the plant hormones related to plant growth (GA3 and IAA) were observed, but negative correlations were found between ABA and plant density (r = -0.872, P<0.05) and height (r = -0.833, P<0.05). The results suggest that soil salinity might restrict plant growth and biomass accumulation by reducing the synthesis of GA3 and IAA and increasing the synthesis of ABA under salt stress.
Determination of the In vitro Effect of Trichoderma harzianum on Phytopathogenic Strains of Fusarium oxysporum
Authors: ALTINOK Hacer Handan , ERDOGAN Oktay
Published: July 2019

Fusarium oxysporum is a well-known soil-borne fungi and it is difficult to control their pathogenic strains by conventional strategies. The cultures of two strains of Trichoderma harzianum (T16 and T23) were examined in laboratory conditions and with pot experiments for the control of pathogenic strains of Fusarium oxysporum f. sp. melongenae (Fomg), Fusarium oxysporum f. sp. lycopersici (Fol), Fusarium oxysporum f. sp. niveum (Fon) and F. oxysporum f. sp. melonis (Fom). The T16 and T23 strains showed significant inhibition of mycelial growth in the pathogenic strains of F. oxysporum and the maximum inhibition were recorded when the T. harzianum strain T16 was used (72.69%). Both T. harzianum strains produced volatile and non-volatile metabolites that inhibited growth of F. oxysporum strains on PDA medium. In vitro colonization study demonstrated the root-colonizing ability of these antagonists. The interaction between T. harzianum isolates (T16 and T23) and pathogenic F. oxysporum hyphae showed no overgrowth, hyphal coiling, cell wall degradation or any hyphal penetration around any of the tested F. oxysporum hyphae. Pre-treatment of soil with T16 significantly reduced the severity of Fusarium wilt disease. The disease severity in control plants reached to 90-95% whereas those of the T16-Fomg and T16-Fol treated seedlings of eggplants were 37.74% and 47.12%, respectively, on the 21st day. In this study, while both T. harzianum isolates had a considerable antagonistic effect on the tested pathogens, T16 was found to be more successful than T23. The strong repressive effect of T. harzianum (T16) towards pathogenic Fusarium oxsporum can be applied in biological control of these pathogens.

Published: July 2019

One of the most important orange fruit diseases is blue mold which cause by Penicillium italicum that is responsible for important economic losses. This study investigated biochemical changes in exo-mesocarp layers of orange fruits related to host- pathogen- yeast interactions. Initial result showed that among eight strains isolated, the most effective antagonist were belonged to two species of Pichia kluyveri (M45) and Rhodotorula mucilaginosa (M61). These isolates were selected for biochemical evaluation. In order to assessment of biochemical changes, the orange fruits were inoculated with 40 Âµl of yeast cell suspension and after 24 h, the wounds were inoculated with 20 Âµl of conidial suspension of P. italicum. The analysis of variance showed that all of the measured biochemical characterises were significant in both layers by treatments (yeast isolates; pathogen; yeast isolates + pathogen and control) (P â‰¤ 0.01), including POD, CAT and Î²-1, 3-glucanase activities and total phenolic compounds. Also result showed that when the yeast isolates (M45 or M54) were inoculated into wounds with the pathogen, it stimulated the orange to increase produce of total phenol and enzymes activity (POD, CAT and Î²-1, 3-glucanase) and these changes were related to incubation time. The result showed that understanding biochemical mechanism derived from plant-pathogen-antagonist interactions is essential for investigating the dynamics of infectious processes.

Published: July 2019

Sedum spectabile is an ornamental herbaceous perennial considered as a long-day plant. Varying levels of hormones and sugars possibly affect flower bud formation. This study aimed to determine the changes in endogenous hormones, sugars, and respiration levels in leaves and in apical buds. In addition, the current research was also conducted to observe the morphological changes during the induction, initiation and development of flower buds. Results showed that the periods of floral induction, initiation and development of S. spectabile were the period from 0 d to 1 d, 2 d to 10 d and after 11 d respectively under long day of 20 hours. High zeatin level in apical buds was conducive to floral induction; the increasing levels of gibberrelin and indole acetic acid favor floral initiation; floral development was regulated by mutually synergistic and antagonistic relationships of hormones. The total starch content in leaves remarkably decreased during floral induction. Moreover, soluble sugar content increased and reached the maximum level at 20 d of the treatment period. Afterward, soluble sugar content declined rapidly and was probably transported to the apical buds for rapid floral development. Furthermore, the total respiration of leaves maintained an upward trend; the cytochrome pathway also maintained an increasing trend after the plants were treated for 20 d. Such changes may favour the morphological differentiation of apical buds in floral development.

Authors: ÇETINBAS Aslıhan , ÜNAL Meral
Published: July 2019

In this study, the development of male reproductive organ was analysed in Crataegus tanacetifolia (Lam.) Pers., endemic to Turkey. Androecium is composed of 20 stamens which are attached at the base of the filaments. The anther wall formation follows the dicotyledonous type. The undifferentiated anther is ovoid-shaped, and the differentiation starts with the appearance of archesporial cells. Mature anthers are dorsifix and tetrasporangiate. The anther wall is composed of an epidermis, endothecium, two or three rows of middle layers and secretory tapetum. Endothecial cells show fibrous thickening. Tapetum is characterized by enlarged secretory types with binucleate cells, which presented an intense reaction with regard to proteins, insoluble polysaccharides and lipids. Features of chromatin condensation and nucleus disorders identified with the application of DAPI (4Â´,6-diaminido-2-phenylindole) point out programmed cell death. Epidermal and endothecial layers remain intact until anther dehiscence; however, middle layer and tapetum disappear during development. At the end of regular meiotic division, tetrahedral microspore tetrads are formed. Pollen grains are tricolparatae, tectate and sphaeroidea. Exine is made up of lipoidal substances and proteins, but the intine includes insoluble polysaccharides. Further, cytoplasm of pollen grains are rich in proteins, lipids and insoluble polysaccharides.

Published: July 2019

Este estudo teve como objetivo desenvolver modelos de redes neurais artificiais para prever o desempenho financeiro das empresas pertencentes e não pertencentes aos níveis de governança da B3 (antiga BM&FBovespa). Os modelos foram desenvolvidos utilizando dados das empresas do mercado de ações brasileiro no período de 2005 a 2017. Estipulou-se como hipótese que os modelos que corresponderiam às empresas pertencentes aos segmentos de governança obteriam maior sucesso na previsão do desempenho financeiro das empresas em comparação aos que representariam as que não estavam nos níveis de governança. Os resultados confirmaram a hipótese. Além disso, eles indicaram que o desempenho financeiro das empresas não pertencentes aos níveis de governança corporativa é mais sensível a oscilações ocorridas no ambiente externo, o que dificulta a previsão desse indicador. Este trabalho foi o primeiro no Brasil a construir modelos por meio de técnicas de inteligência artificial – mais especificamente a rede neural backpropagation – para prever o desempenho financeiro da empresa relacionando-o a aspectos da governança corporativa.

Published: July 2019

Las mujeres adultas y mayores son las principales cuidadoras (y personas cuidadas) de la vejez más dependiente. También son las protagonistas de los programas de apoyo para cuidadoras/es, como demandantes y perceptoras y como profesionales que ofrecen este soporte, siendo el acceso a estos programas distinto para la población rural o urbana. El objetivo principal de este artículo es el análisis de los problemas y situaciones relacionadas con las necesidades de esta población demandante de programas y abordar el tratamiento de estos apoyos. Para ello, se utiliza una metodología cualitativa y cuantitativa, siguiendo una estrategia de triangulación. Los resultados muestran que, aunque las mujeres solicitan y participan en estos programas (cuyos efectos positivos en su calidad de vida se ha comprobado), estos resultan insuficientes y no cubren las necesidades y nuevas demandas de cuidado, lo que se traduce en que una gran mayoría de mujeres sigue encargándose del trabajo de cuidar en solitario. En la misma línea, su presencia es minoritaria en el diseño, gestión y coordinación de estos programas más ausentes todavía en zonas rurales, en la recientemente llamada “España vaciada”. En consecuencia, se requiere más oferta de programas/apoyos de tipo psicosocial (individual o grupal), de ocio y tiempo libre, y de formación para este perfil de cuidadoras y responsables de programas. Éstas y otras conclusiones son las que se desarrollan desde el Programa ENCAGE-CM1 y del Proyecto CM:LEDYEVA2.

Stochastic Contests with Linex Utility Functions
Authors: CANBOLAT Pelin G.
Published: July 2019

In this paper, we analyze the Nash equilibrium in a class of winner-takes-all stochastic contests among players with linear-exponential (linex) utility functions. In this contest, players are required to make upfront investments, which collectively determine their winning probabilities. We first show that a Nash equilibrium for such a contest exists and is unique, then set the equilibrium conditions, and study the properties of these conditions to gain insights into the structure of equilibrium. We show that the total equilibrium investment is bounded below and above, that the equilibrium has a cut characterization with respect to wealth, and that wealthier players invest more. The latter implies that richer is likely to get richer. For the special case with identical players, we show that an increase in the wealth or a decrease in the weight on the nonlinear component of the linex utility function results in an increase in the equilibrium investment.

Samples were collected from a network of ten Critical Zone Observatories (CZOs) across the US: Southern Sierra (CA), Boulder Creek (CO), Reynolds (ID), Shale Hills (PA), Calhoun (SC), Luquillo (PR), Intensively-Managed Landscapes (IML) (IL/IA/MN), Catalina/Jemez (AZ/NM), Eel (CA), and Christina (DE/PA). Volunteers from each CZO excavated two separate soil profiles selected to represent distinct soil types or parent materials or to contrast with each other in another major characteristic, such as elevation, dominant vegetation type, or landscape positions. Soils were collected at peak greenness, as estimated from Normalized Difference Vegetation Index and Enhanced Vegetation Index measured by NASA's MODIS (MODerate-resolution Imaging Spectroradiometer) instrument aboard theTerrasatellite. These collections were conducted between April 2016 and November 2016, with the exception of the EEL CZO samples, which were collected May 2017. Volunteers were asked to sample by integrating soil in 10 cm increments, every 10cm increment to a depth of at least 100 cm, although it was not possible to reach these depths at all sites. If a particular profile within a site extended beyond 100 cm, an optional sample of the last 10 cm to refusal were also collected. In contrast, the Luquillo CZO sites were collected at every 10-cm interval, covering 3 cm, with the exception of the surface soil, which contained the top 6 cm of surface soil. For all but two sites, soil from the pit or core was collected sterilely using either a soil knife or a coring auger inserted into the pit wall horizontally, integrating soil from each 10 cm increment. The sites from the IML CZO (GOOS and PRAR) and Christina (FLUD and AGRI) CZO were sampled by core auger, and were each composited from 4 cores. Soil samples, once received at the University of California, Riverside, a portion of each field sample was sieved (2mm opening, ASTM No.10), and the sieved portion was homogenized by shaking and/or mixing the sample within the sterile sample bag. The sieved, homogenized samples were divided into subsamples for further analysis.For some soils (particularly some wet, finely textured depth intervals), sieving was not practical under field-fresh conditions. These samples were homogenized by mixing, but during the subsampling process, larger root fragments and granules were excluded by visual observation. In addition, SHAL sites from the Shale Hills CZO samples from 70—100cm consisted almost entirely of medium-sized rocks (“cobbles” in USGS nomenclature); soil was collected both by manually crushing rocks with a ceramic mortar and pestle to pass through the sieve and by scraping soil from the faces of the cobbles—for this analysis, only the crushed-rock samples were used.
AS INÚMERAS ROTAS EM “NUNCA MAIS” DE EDYR PROENÇA

Published: July 2019

Este trabalho tem por finalidade fazer uma análise de como ocorre a relação entre as estruturas narrativas do texto literário, isto é, a relação entre uma dada ação narrativa que conduz o leitor a criação de um horizonte, que pode ou não ser, pelas ações futuras, preenchido ou confirmado. Sendo que esse horizonte, ao tornar-se noutra ação, gera outro horizonte, dando, assim, continuidade ao desenrolar da narrativa. De qualquer forma, essa relação entre as ações sofre influências do eixo temporal que, por sua vez, funciona como base para que essa relação seja possível, organizando, por sua vez, a coerência ou aquilo que dará sentido à obra. A partir desses pressupostos analisaremos a multiplicidade de interpretações cabíveis, que podem ser criadas como horizonte, tendo a obra literária como de natureza perspectivística, no conto Nunca mais de Edyr Proença, com a finalidade de se chegar, ao final do conto, à melhor interpretação possível em relação ao personagem Dico. Para tanto, partiremos dos pressupostos dos estudos de, principalmente, Iser (1996) e Bakhtin (2015) entre outros.
NARRAR PARA (SOBRE)VIVER: OS HOMENS-NARRATIVAS DE MILTON HATOUM
Authors: LOUREIRO JUNIOR João Pereira , ALMEIDA Carlos Henrique Lopes de
Published: July 2019

Ao longo da trajetória humana, diversas áreas da ciência sempre questionaram a indissociável relação entre o Homem e a Memória. Dos mais variados estudos científicos sobre essa questão, a maioria nunca satisfez por completo a curiosidade humana, apresentando “respostas” ora cientificas demais, ora filosóficas ao extremo. No caminho inverso ao traçado pelo senso comum, a Literatura foi ao encontro desta incógnita, mas não no afã de dissecá-la, senão apenas compreender essa inerência Homem/Memória no que diz respeito a formação de identidades. Em outras palavras, a Literatura, como ciência, tentou decifrar os possíveis caminhos que constroem a identidade cultural do homem pelo viés da memória, tendo como principal foco a tradição da oralidade na formação de vozes narrativas da história humana. É se aventurando às entranhas ficcionais de Relato de um certo oriente de Milton Hatoum que o presente trabalho pretende traçar um painel humano dos personagens-narradores que povoam a Amazônia, tendo como foco de estudo a reconstrução da memória a partir das vozes que transformam meros narradores convencionais em “Homens-narrativas” que, segundo Todorov, dão vida às inúmeras vozes condenadas a narrar a própria solidão.
DISCURSO E IDENTIDADE FEMININA: UMA PROPOSTA DE COMPARAÇÃO ENTRE CONTOS E CRÔNICAS DE CLARICE LISPECTOR
Authors: PEREIRA Anderson Luiz Teixeira , HOLANDA Sílvio Augusto de Oliveira
Published: July 2019

A dimensão estética do texto artístico de Clarice Lispector, manifestada por meio dos elementoscorporificados na obra de arte, permite-nos redimensionar a interpretação de sua obra a umaoutra leitura, cujo enfoque incide sobre a dimensão sociocultural. Com base na metodologiados postulados da Literatura Comparada e dos Estudos Culturais, o presente trabalho visa acomparação entre três contos clariceanos, a saber “Devaneio e embriaguez de uma rapariga”,“Preciosidade” e “O búfalo” — os quais compõem a coletânea Laços de família (1960) — e ascrônicas escritas por Clarice Lispector enquanto trabalhava como jornalista em colunas femininas,textos esses reunidos em Correio Feminino (2006). A finalidade de analisar dois objetos,cuja diferenciação não se resume a uma simples questão de gênero, é observar como ambos ostextos, por mais que trabalhem com o mesmo eixo temático: a figura feminina, eles refletemdiscursos sobre a identidade feminina e como estão contingenciados ao sujeito da enunciaçãoe ao meio cultural de onde partem. Portanto, é necessário refletir, a partir dos objetos selecionadosneste trabalho e os considerando como uma representação de uma cena cultural, sobre aproblematização de um discurso que construa ou desconstrua uma identidade feminina normativana obra da escritora modernista brasileira. Nesse sentido, sua obra manifesta-se, também,como produto de uma microfísica do poder (FOUCAULT, 1979), uma vez que, integrada àdimensão sociocultural, ela permite confrontar ideologias e valores dos laços sociais modernos.
A LITERATURA COMO DIREITO UNIVERSAL: UMA ANÁLISE DOS SENTIMENTOS DO PERSONAGEM PAULO HONÓ- RIO DA PBRA “SÃO BENEDITO”, DE GRACILIANO RAMOS E SUA APLICABILIDADE NO AMBIENTE ESCOLAR

A literatura nem sempre foi acessível às camadas menos prestigiadas da sociedade, pois durantemuitos anos ela esteve restrita a uma pequena parcela da população que era composta pelaelite burguesa. A literatura é um instrumento de transmissão de valores e conhecimentos, porisso, deveria ser direito de todo e qualquer indivíduo ter acesso a mesma, direito este que deveser disponibilizado, sobretudo, pela escola, proporcionando ao aluno a obtenção de conhecimentosliterários, bem como, a compreensão de sua importância. Este trabalho foi desenvolvidocom base na análise dos aspectos universais e regionais abordados na obra São Bernardo,de Graciliano Ramos ressaltando sua importância para a formação crítica do ser humano, dessaforma, para alcançar os objetivos traçados foi desenvolvida uma pesquisa qualitativa de cunhobibliográfico por meio de estudos teóricos relacionados ao assunto. Com base nos resultados,destaca-se algumas considerações: A literatura representa a expressão e manifestação de umpovo e sua cultura. Através dela foi possível reconhecer as lutas pelos direitos humanos queaté então possibilitou aos indivíduos liberdade de expressão. A obra analisada, São Bernardo,promove reflexão sobre questões universais como os aspectos psicológicos do indivíduo,demostrados pela ganância do personagem Paulo Honório, que procura crescer socialmente,apresentando sua visão de mundo centrada na relação de poder. Assim, é importante atentar quepor meio da literatura é possível promover uma reflexão literária sobre os valores humanos, aexemplo da obra analisada, mas para isso é preciso que a literatura faça sentido para quem ler,e esse sentido poderá ocorrer por meio do incentivo individual e coletivo à prática da leitura. Apesquisa desenvolvida para o estudo deste trabalho tem a contribuição dos seguintes autores:Amado, Berviam e Da Silva (2007), na área da metodologia cientifica e Bosi (2006), Cândido(1997), Evangelista, Brandão e machado (2003), Ramos (2002), para o arcabouço teórico.
ASSIMETRIAS DE PODER: GÊNERO, CLASSE E ETNIA EM DALCÍDIO JURANDIR
Authors: SILVA Joanna da
Published: July 2019

O presente artigo tem por objetivo refletir acerca da condição e representação feminina no contexto sociocultural da Amazônia paraense no início do séc. XX, que se faz representar de maneira crítica na obra Três casas e um rio (1958), de autoria do escritor paraense Dalcídio Jurandir. O protagonismo da personagem negra dona Amélia, aqui eleita personagem central da discussão, e sua condição de subordinação e marginalização presente na narrativa, nos possibilita problematizar questões em torno da articulação entre sexo/gênero, entrecruzadas com outros eixos identitários, como classe e etnia, e sua influência nas práticas discursivas e sociais que sustentam desigualdades e exclusões que acometem muitas mulheres, produzindo assimetrias de poder entre os sujeitos. O aporte teórico utilizado nessa discussão pauta-se na Teoria Feminista e de Gênero, que subsidiarão a análise em torno do tema ora eleito objeto de estudo.
NAS DOBRAS DAS ONDAS DE DANIELLE FONSECA
Authors: Pimentel Vera Maria Segurado
Published: July 2019

O artigo, em questão, visa analisar o trabalho “As dobras somos nós” da artista visual, Danielle Fonseca, vencedor da XVII edição do Salão UNAMA de Pequenos Formatos, com base em autores como Lins (2009), Santaella (2003, 2007), Machado (2003), entre outros. O estudo aborda, primeiramente, um histórico da vídeo arte no Brasil, a  imagem em movimento, a relação entre a teoria de Giles Deleuze das dobras com o surfe e posteriormente, uma análise a partir da semiótica aplicada sobre o vídeo em questão. As teorias sígnicas de Peirce contribuíram de maneira significativa para as análises realizadas na vídeo arte, revelando as várias relações de significados presentes nas imagens do surfista, equilibrando-se na prancha e adentrando o famoso “tubo” que todo praticante busca obsessivamente.Palavras-chave: Surf. Ondas.  Dobras.  Deleuze.
O GAMBÁ E AS TROCAS RITUAIS NA FESTA DE SÃO BENEDITO EM ALMEIRIM/PA
Authors: Figueiredo Vanessa Lima Brasil , De Carvalho Luciana Gonçalves
Published: July 2019

Este é um registro etnográfico da festividade de São Benedito em Almeirim, Pará. Partindo do histórico da celebração, reconstituído com base na memória de membros da Irmandade de São Benedito e da família Castro, responsável por sua introdução no município, o artigo foca a execução do gambá como sua expressão mais característica. Por meio da participação, observação e documentação de diversas etapas rituais da festa de 2017, constatou-se que o gambá executado para o santo faz interagir uma ampla cadeia de pessoas em um circuito de dons e contradons variados, dos quais foram destacados: a comida, o canto e a dança. Assim, as trocas rituais desses três elementos (re)afirmam os laços entre os humanos, e entre eles e São Benedito, ao mesmo tempo que potencializam relações de parentesco, afinidade e amizade que marcam a trajetória histórica da festa e do gambá em Almeirim.
“VIVA O GLORIOSO!” UM ESTUDO SOBRE A FESTA DA IRMANDADE DE SÃO BENEDITO EM ANANINDEUA/PA

Published: July 2019

O objetivo do artigo será apresentar a festa realizada pela irmandade de São Benedito na região metropolitana de Belém, na cidade de Ananindeua no Estado do Pará, buscando identificar as estratégias de construção de identidade dos devotos do Glorioso Santo Negro, realizada por migrantes vindos da cidade de Bragança, localizada no Nordeste do mesmo Estado. Discutindo todo um processo de perseguição, rejeição e conflitos que desafiam o tempo e guardam heranças herdadas desde a diáspora dos africanos escravizados no Brasil, expressados através do canto, da dança e da resistência negra, até os dias atuais, ainda manifestados nos cortejos e rituais em devoção e homenagem a São Benedito.
