Abstract Introduction The Internet Gaming Disorder Scale – Short Form (IGDS9-SF) assesses the severity, harmful effects and/or consequences of excessive online and offline gaming. Its conciseness and theoretical foundations on current diagnostic criteria of gaming disorders make it a useful resource for clinical and screening settings. Objective To describe the process of cross-cultural adaptation of the IGDS9-SF to the Brazilian context. Methods The cross-cultural adaptation involved the steps of independent translation of the instrument, synthesis version, back-translation, pre-test and elaboration of the final version. Content validity assessment was conducted by a multidisciplinary committee of experts and consisted of both a quantitative analysis (calculation of content validity coefficients – CVC) and a qualitative analysis (assessment of the experts’ comments and suggestions). The pre-test sample consisted of 30 gamers with variable sociodemographic characteristics. Results The cross-cultural adaptation of the scale followed the proposed protocol, and the CVC was satisfactory (≥ 0.83) for all the structures and equivalences assessed. Most of the suggestions made by the experts were accepted (mainly adjustments and language standardization). The gamers who participated in the pre-test judged the scale easy to understand and did not suggest changes. Discussion The Brazilian version of the IGDS9-SF showed adequate content validity and is available for researchers and clinicians, as well as for the investigation of additional psychometric characteristics.

Abstract Euterpe precatoria (Açaí-do-Amazonas) produces fruits of which the fresh pulp is consumed. It is almost exclusively collected by extractivist farmers, because no selected genotypes are available for the establishment of plantations. For the domestication and breeding of the species, mating system studies are needed for strategy formulation. This study evaluated the mating system of a natural population of E. precatoria. Thirteen progenies were genotyped with 13 microsatellite loci by capillary electrophoresis in an automated DNA sequencer. Estimates of single-locus and multilocus outcrossing rates were 1.0, and paternity correlation was low ( r ^ p ( m )>= 0.293). Euterpe precatoria families consist mainly of half-sibs and the reproductive strategy of the species is allogamy.

OBJECTIVE: We describe an IncX4 pHC891/16mcr plasmid carrying mcr-1 in a colistin-resistant and carbapenem-susceptible E. coli isolate (HC891/16), ST156, which caused a blood infection in a Brazilian patient with gallbladder adenocarcinoma. METHODS: Strain HC891/16 was subjected to whole genome sequencing using the MiSeq Platform (Illumina, Inc., USA). Assembly was performed using Mira and ABACAS. RESULTS: The isolates showed resistance only to ciprofloxacin, ampicillin and cefoxitin, and whole-genome sequencing revealed the presence of aac(6’)Ib-cr and blaTEM1. CONCLUSION: Our findings warn of the possible silent dissemination of colistin resistance by carbapenem-susceptible mcr-1 producers, as colistin susceptibility is commonly tested only among carbapenem-resistant isolates.

Avaliou-se a variabilidade genética em progênies de Eucalyptus dunnii Maiden para resistência à ferrugem (Puccinia psidii). Experimentos de campo foram instalados em duas regiões edafoclimáticas.Progênies de polinização aberta foram estabelecidas em um delineamento emblocos casualizados. Em condições de campo foram avaliadas 60 e 48 progênies emdois locais, com seis repetições e oito plantas por parcela. Instalou-se tambémum experimento em ambiente controlado, com 53 progênies, em blocoscasualizados, com seis repetições e nove plantas por parcela. Foram avaliadas altura da planta e a severidade de ataque que determinam a fase mais suscetível à doença foliar. A população de E. dunnii estudada apresentou altavariabilidade genética para resistência à ferrugem, com coeficiente de variaçãogenética de 36, 07% e 70% das progênies avaliadas foram imunes a ferrugem. Istoindica alto potencial para seleção e melhoramento da espécie.

This study investigated the genetic variability in progenies of Eucalyptus dunnii Maiden for resistance against rust (Puccinia psidii). Field experiments were installed in two regions with differentsoil-climatic conditions. Open-pollinated progenies were established in arandomized complete block design. Sixty and 48 progenies were evaluated underfield conditions at two sites, respectively, with six replications and eight trees per plot. In another experiment in a controlled environment, 53 progenies were evaluated in randomized blocks with six replications and nine plants perplot. The following traits were evaluated: plant height, severity of pestattack and the most susceptible stage to the leaf disease. The genetic variability for rust resistance in the E. dunnii population under studywas high, with a genetic coefficient of variation of 36.07%; 7% of thee valuated progenies were rust-resistant. It indicates a high potential for selection and breeding of the species.

Plantas daninhas e microrganismos do solo se interagem na interface solo/raiz promovendo vantagens para o desenvolvimento e estabelecimento de ambos. Objetivou-se com este trabalho avaliar o crescimento e o acúmulo de nutrientes em oito espécies de plantas daninhas (Ageratum conyzoides L., Bidens pilosa L., Cenchrus echinatus L., Conyza bonariensis L., Echinochloa crus-galli L., Eleusine indica L., Ipomoea grandifolia L. e Lolium multiflorum L.) e nas culturas de feijão e milho, cultivadas, por 50 dias, em substrato fumigado com brometo de metila. Avaliações referentes à altura, área foliar, número de folhas, matéria seca da parte aérea e das raízes e teor relativo dos nutrientes, foram realizados aos 50 dias após emergência das plântulas. Observou-se efeito positivo da fumigação do substrato no crescimento, número de folhas, área foliar, altura de plantas e acúmulo de nutrientes nas plantas daninhas gramíneas em relação às dicotiledôneas. Conyza bonariensis foi a mais afetada pela fumigação do solo, apresentando índices de matéria seca, número de folhas, área foliar, altura e acúmulo de nutrientes em torno de 50% menores em relação às plantas crescidas em solo normal. A fumigação influenciou também o ciclo vegetativo das plantas, sendo este menor para as espécies B. pilosa, E. indica e C. echinatus. Observou-se, ainda, acúmulo de fósforo 20 e 30% menor em plantas de Bidens pilosa e Conyza bonariensis, respectivamente, quando cultivadas em solo esterilizado. As culturas de feijão e milho foram menos afetadas pela fumigação do solo em comparação às plantas daninhas.

Weeds and soil microorganisms interact with each other in the soil/root interface, promoting the development and establishment of both. The objective of this study was to evaluate the growth and nutrient accumulation in eight species of weeds (Ageratum conyzoides L., Bidens pilosa L., Cenchrus echinatus L., Conyza bonariensis L., Echinochloa crus-galli L., Eleusine indica L. Ipomoea grandifolia L. and Lolium multiflorum L.) and in bean and corn crops grown for 50 days in a substrate fumigated with methyl bromide. Assessments relating to the height, leaf area, leaf number, dry weight of shoots and roots and relative content of nutrients were carried out 50 days after seedling emergence. A positive effect of soil fumigation was observed on the growth, leaf number, leaf area, plant height and accumulation of nutrients in monocot weeds in relation to dicots. Conyza bonariensis was the most affected by soil fumigation, with levels of dry matter, leaf number, leaf area, height and accumulation of nutrients approximately 50% lower than plants grown in normal soil. Fumigation also influenced the growth cycle of the plants, which was lower for B. pilosa, E. indica and C. echinatus. We also observed a 20 and 30% lower phosphorus accumulation in Bidens pilosa and Conyza bonariensis, respectively, when grown in the sterilized soil. Overall, the bean and corn crops were less affected by soil fumigation than the weeds.

Objetivou-se, neste trabalho, avaliar o efeito do déficit hídrico sobre as características fisiológicas e produtivas do feijão-caupi e selecionar genótipos tolerantes à seca. Avaliaram-se a condutância estomática, o potencial hídrico foliar, a temperatura das folhas e a produtividade de grãos de 20 genótipos de feijão-caupi nas condições de solo e clima de Teresina, Piauí, no ano de 2008 e se conduziram dois experimentos em delineamento de blocos ao acaso com 20 tratamentos e quatro repetições, um sob déficit hídrico durante a fase reprodutiva e outro sob irrigação plena, para fins de comparação. O déficit hídrico, que foi obtido aplicando-se aproximadamente metade da lâmina requerida pelo feijão-caupi, reduziu em 72% a condutância estomática, 62% o potencial de água nas folhas, 60% a produção de grãos e aumentou em 11,7% a temperatura foliar. Nas condições de déficit hídrico treze genótipos produziram acima da média (466 kg ha-1), com destaque para o BRS-Paraguaçu, Pingo-de-ouro-1-2 e Pingo-de-ouro-2, que produziram 712 kg ha-1, 667 kg ha-1 e 642 kg ha-1, respectivamente. Em média, a produtividade de grãos dos genótipos sob irrigação plena foi 150% superior.

The objective of this study was to evaluate physiological and productive characteristics of cowpea under water deficit and total irrigation, under soil and climate conditions of Teresina, Piauí State, in 2008. The stomatal conductance, leaf water potential, leaf temperature and grain yield of twenty cowpea cultivars were evaluated. Two experiments were carried out in a randomized block design with 20 treatments and four replications, one under water deficit during the reproductive phase and another one under total irrigation. The water deficit was obtained applying half of the water depth required by cowpea. The water deficit reduced 72% of the stomatal conductance, 40% the leaf transpiration, 62% of the leaf water potential, 60% of the grain yield and increased 11.7% the leaf temperature. Under water deficit, 13 genotypes produced above average (466 kg ha-1), and BRS-Paraguaçu, Pingo-de-ouro-1-2 and Pingo-de-ouro-2 presented the best grain yield with712 kg ha-1, 667 kg ha-1 and 642 kg ha-1, respectively. The average grain yield of the experiment under total irrigation was 150% higher.

O objetivo deste trabalho foi desenvolver e validar um modelo matemático para estimar a duração do ciclo do algodoeiro (Gossypium hirsutum L. r. latifolium hutch) no Estado de Goiás, aplicando o método de graus-dia (GD) e considerando sua variação espaçotemporal. O modelo foi desenvolvido por meio de combinação linear entre altitude, latitude, longitude e a variação temporal, representada pela série trigonométrica incompleta de Fourier. Os parâmetros do modelo foram ajustados, por meio de regressão linear múltipla, aos dados de GD para o algodoeiro, acumulados entre 15°C e 40°C. Os dados utilizados de temperaturas máxima e mínima foram obtidos de séries históricas de 21 estações meteorológicas, com períodos de observações variando entre 8 e 24 anos. A validação do modelo foi feita comparando-se a duração da fase entre a emergência e 90% de capulhos abertos de cultivares de algodoeiros plantados em lavouras comerciais. O coeficiente de determinação resultante do ajuste do modelo aos dados observados foi de 0,84. Os resultados dessa comparação mostraram que o modelo proposto teve um desempenho muito bom, conforme indicado pelo coeficiente de correlação de Pearson de 0,90 e o índice de concordância de Willmott de 0,94, que resultaram em um índice de desempenho de 0,85.

The objective of this work was to develop and validate a mathematical model to estimate the duration of cotton (Gossypium hirsutum L. r. latifolium hutch) cycle in the State of Goiás, Brazil, by applying the method of growing degree-days (GD), and considering, simultaneously, its time-space variation. The model was developed as a linear combination of elevation, latitude, longitude, and Fourier series of time variation. The model parameters were adjusted by using multiple-linear regression to the observed GD accumulated with air temperature in the range of 15°C to 40°C. The minimum and maximum temperature records used to calculate the GD were obtained from 21 meteorological stations, considering data varying from 8 to 20 years of observation. The coefficient of determination, resulting from the comparison between the estimated and calculated GD along the year was 0.84. Model validation was done by comparing estimated and measured crop cycle in the period from cotton germination to the stage when 90 percent of bolls were opened in commercial crop fields. Comparative results showed that the model performed very well, as indicated by the Pearson correlation coefficient of 0.90 and Willmott agreement index of 0.94, resulting in a performance index of 0.85.

Abstract: En | Text: En | PDF: En

The Medium-Term Operation Planning (MTOP) of hydrothermal systems aims to define the generation for each power plant, minimizing the expected operating cost over the planning horizon. Mathematically, this task can be characterized as a linear, stochastic, large-scale problem which requires the application of suitable optimization tools. To solve this problem, this paper proposes to use the Nested Decomposition, frequently used to solve similar problems (as in Brazilian case), and Progressive Hedging, an alternative method, which has interesting features that make it promising to address this problem. To make a comparative analysis between these two methods with respect to the quality of the solution and the computational burden, a benchmark is established, which is obtained by solving a single Linear Programming problem (the Deterministic Equivalent Problem). An application considering a hydrothermal system is carried out.

No meio rural, a água de consumo humano é frequentemente captada por meio de sistemas precários. O objetivo do trabalho foi o de monitorar parâmetros físicos, químicos e microbiológicos da qualidade de água subterrânea captada em fontes para uso doméstico, relacionando suas posições na paisagem e à presença de proteção física. Trinta e cinco fontes de água subterrânea, localizadas na pequena bacia hidrográfica-PBH do Arroio Lino, área rural do Município de Agudo - RS, foram amostradas e classificadas quanto à proteção física e à posição na paisagem. Monitoraram-se, de janeiro a agosto de 2002, os seguintes parâmetros da água: pH, cor, carbono orgânico solúvel total (COST), N-NO3, N-NH3 e fósforo total (PT), Escherichia coli e coliformes totais. Em geral, os parâmetros variaram com a época de coleta, ficando ora acima, ora abaixo dos Valores Máximos Permissíveis previstos pelo Ministério da Saúde do Brasil. A posição das fontes nas cotas mais altas da paisagem da PBH mostrou-se determinante unicamente para a cor e o PT. A proteção rudimentar mostrou-se eficaz para o PT nas fontes posicionadas em cotas altas, no entanto apresentou respostas discrepantes na parte baixa da paisagem, considerando-se os parâmetros COST e N-NO3. A fonte drenada coletiva, sistema recomendado pela assistência técnica oficial, mostrou-se a mais eficaz em evitar a contaminação por Escherichia coli, restringindo também coliformes totais, fósforo total e N-NO3 em relação à fonte individual. A posição das fontes na paisagem e a presença de proteção física rudimentar podem ser utilizadas como critério parcial ao uso de fontes para captação de água.

In rural areas, water for human consumption is often captured by insecure systems. The objective of this work was monitoring some parameters of the quality of groundwater taken from sources, pointing out their position in the landscape and the presence of physical protection. For this , 36 sources in the watershed of Arroio Lino, a rural area of Agudo, RS, Brazil, were sampled and classified according their physical protection and position in the landscape. A monitoring program, from January to August 2002, was carried out to analyze the following parameters: pH, color, total soluble organic carbon - TSOC, N-NO3, N-NH3 and total phosphorus, E. coli and total coliforms. The parameters values changed with the time of collection and were often above the Maximum Allowable values provided by the Brazilian Ministry of Health. A rudimentary protection was efficient to the PT of the sources located in high levels; however it has present discrepant results for the low part of the landscape, considering the parameters TSOC e N-NO3. The collective drained source, system recommended by the official technical assistance, was the most efficient to avoid contamination by Escherichia coli, restricting also the levels of total coliforms, total phosphorus and N-NO3 as compared to the individual sources. The sources position in the landscape and the presence of a rudimentary physical protection can be employed as a partial criterion to accept that a water source be used for collecting water.

The chaotic low energy region (chaotic sea) of the Fermi-Ulam accelerator model is discussed within a scaling framework near the integrable to non-integrable transition. Scaling results for the average quantities (velocity, roughness, energy etc.) of the simplified version of the model are reviewed and it is shown that, for small oscillation amplitude of the moving wall, they can be described by scaling functions with the same characteristic exponents. New numerical results for the complete model are presented. The chaotic sea is also characterized by its Lyapunov exponents.

Abstract This work aimed to evaluate several N2-fixing and non N2-fixing tree species, in relation to their surviving rate and growth in grass pasture, in order to form a wood-pasture system at the Atlantic Forest region. Two experiments were carried out in a grass pasture area, one with five N2-fixing tree species (Acacia holosericea, Mimosa caesalpiniaefolia, Anadenanthera macrocarpa, Enterolobium contortisiliquum and Pseudosamanea guachapelle) and other with five non N2-fixing (Schinus terebinthifolius, Eucalyptus grandis, Tabebuia chrysotricha, Khaya senegalensis and Senna siamea). M. caesalpiniaefolia, E. contortisiliquum, A. holosericea and E. grandis were the most recommended species for wood - pastures system mainly due to their rapid establishment rate.

Resumo Este trabalho teve o objetivo de avaliar diversas espécies arbóreas fixadoras e não fixadoras de N2, quanto à sobrevivência e crescimento em pastagem, para formar um sistema silvipastoril na região da Mata Atlântica. Dois experimentos foram instalados em uma área de pastagem, um com cinco espécies fixadoras de N2 (Acacia holosericea, Mimosa caesalpiniaefolia, Anadenanthera macrocarpa, Enterolobium contortisiliquum e Pseudosamanea guachapelle) e outro com cinco não fixadoras (Schinus terebinthifolius, Eucalyptus grandis, Tabebuia chrysotricha, Khaya senegalensis e Senna siamea). Mimosa caesalpiniaefolia, Enterolobium contortisiliquum, Acacia holosericea e Eucalyptus grandis foram as espécies mais recomendadas para arborização de pastagem quanto a rapidez de estabelecimento.

Abstract In a regenerating forest in Paraty-RJ, four N2-fixing tree species (Acacia holosericea, Mimosa caesalpiniifolia, Anadenanthera macrocarpa and Enterolobium contortisiliquum) and two Non-N2- fixing (Schinus terebinthifolius and Eucalyptus grandis) were transplanted. N2-fixing tree species were inoculated with rhizobia and arbuscular mycorrhizal fungi (AMF) while Non-N2-fixing tree species only with AMF. Otherwise, half of the plants were inoculated with P-solubilizing bacteria. P-solubilizing bacteria did not increase the growth and plant nutrition after field transplantation. M. caesalpiniifolia and E. contortisiliquum showed better performance being the most recommended species for enrichment of regenerating forest.

Resumo Numa área de capoeira em regeneração em Paraty-RJ, foram introduzidas quatro espécies arbóreas fixadoras de N2 (Acacia holosericea, Mimosa caesalpiniifolia, Anadenanthera macrocarpa e Enterolobium contortisiliquum) e duas não fixadoras (Schinus terebinthifolius e Eucalyptus grandis). As espécies fixadoras foram inoculadas com rizóbio e fungos micorrízicos arbusculares (FMAs) enquanto que as não fixadoras apenas com FMAs. Além disso, metade das mudas foi inoculada com bactérias solubilizadoras de fosfato. As bactérias solubilizadoras não beneficiaram o crescimento e nutrição das plantas após o transplante para o campo. M. caesalpiniifolia e E. contortisiliquum apresentaram melhor performance sendo mais recomendadas para enriquecimento de capoeiras em regeneração.

Em muitos países, o Enterovírus 71 (EV-71) família Picornaviridae é associado a doença de pé-mão e boca e doenças neurológicas agudas enquanto que no Brasil esse vírus está mais associado às últimas. O objetivo desta pesquisa foi utilizar em estudos moleculares e soroepidemiológicos, o primeiro isolamento de EV-71 obtido na região norte do Brasil. No período de janeiro de 1998 a dezembro de 2000 foram coletadas 88 amostras (44 casos de PFA) de fezes das quais, duas (2,2%) foram positivas para EV-71 (73442/PA/99). A seqüência de nucleotídeos do gen que codifica a proteína VP1 mostrou que o isolado 73442/PA/99 foi similar às cepas de EV-71 pertencentes ao grupo B- mais próxima das norte americanas. Teste de neutralização com 389 amostras de soro colhidas no período de janeiro de 1998 a novembro de 2001, de indivíduos com idade de 0 a 15 anos residentes na cidade de Belém, Estado do Pará mostrou os seguintes resultados em relação ao isolado 73442/PA/99 e ao protótipo BrCr: 207 indivíduos (53,2%) tinham anticorpos neutralizantes para ambos os vírus, 167 (42,9%) não tinham anticorpos e 15 tinham anticorpos para um dos dois vírus. Somente 20,2% das crianças com idade de 0 a 3 anos tinham anticorpos neutralizantes para EV-71, indicando que essas crianças estavam mais suscetíveis à infecção. Tanto o estudo de soroprevalência quanto o de sequenciamento da VP1 foram importantes para demonstrar a propagação e o padrão molecular do EV-71 circulante na região norte do Brasil.

In many countries, the Enterovirus 71 (EV-71) Picornaviridae family is associated to hand, foot and mouth disease in addition to acute neurological diseases while in Brazil these viruses are more closely associated to the latter group. The aim of this research was to use the first EV-71 isolate of the Northern region of Brazil in molecular and seroepidemiologic studies. Two (2.2%) out of 88 stool samples (44 cases of AFP), collected from January 1998 to December 2000 were positive for EV-71 isolation (73442/PA/99). Nucleotide sequence of the gen that codifies the VP1 protein showed that isolate 73442/PA/99 was similar to the EV-71 strains belonging to genotype B - more closely identified with EV-71 from North America. Neutralization test with 389 sera samples collected from January 1998 to November 2001, from individuals ranging from 0 to 15 years of age living in the city of Belém, State of Pará showed the following results in relation to isolate 73442/PA/99 and prototype BrCr: a total of 207 individuals (53.2%) had neutralization antibodies to both viruses, 167 (42.9%) had no antibodies and 15 showed the presence of neutralizing antibodies to one of the two viruses. Only 20.2% of the children aged 0 to 3 had neutralizing antibodies to EV-71, indicating that these children were more susceptible to the infection. Both the seroprevalence study and VP1 sequencing were important to demonstrate the spread and the molecular pattern of the EV-71 circulating in the Northern Region of Brazil.
