Abstract: The main goal of this research study was to establish the physicochemical characteristics of sewage sludge, and the nutrients needed to enhance the properties of soil with a view to exploiting were potential for agriculture. The example used was the cultivation of radish (Raphanus sativus). The findings are intended as a contribution towards making agriculture sustainable. This study was carried out to assess the response of radish (Raphanus sativus L.) to doses of sewage sludge applied in medium texture soils, and the socioeconomic contributions that such cultivation of radish would make. Levels of 0.25 and 75 ton/ha of sewage sludge plus the equivalent dose of 25 ton/ha of sewage sludge vermin compost by California Red were used after making a randomized experimental design with three replicates. 30 days after sowing radish seeds, the following data were collected: the number of leaves per plant (NLP); plant height (PH in cm); root diameter (RD) and tubercle production (TP ton/ha). In addition, the pH, EC-electric conductivity (EC), and soil organic matter (SOM) were determined. Statistical analysis showed that 25 and 50 tons/ha gave the best results for the parameters assessed. The estimated increase in family mean income from selling radish crops fertilized with sewage sludge is around 17%.

Abstract: Este trabalho teve como objetivo avaliar o efeito do número de folhas e da posi o de fixa o do fruto na planta sobre a produ o de biomassa e a qualidade de frutos de meloeiro tipo Cantaloupe. O experimento foi constituído de quatro tratamentos, delineamento inteiramente casualizado, com 15 repeti es. Os tratamentos foram: 1) 14 folhas/planta, com fruto fixado na posi o intermediária da planta; 2) 14 folhas/planta, com fruto fixado no alto da planta; 3) 14 folhas/planta até a fixa o do fruto no alto da planta, quando foram retiradas as sete folhas imediatamente abaixo do fruto; e 4) 14 folhas/planta até a fixa o do fruto no alto da planta, quando foram retiradas as sete folhas na base da planta. Avaliaram-se: área foliar; área foliar específica; raz o de área foliar; dias para colheita; ciclo cultural; diametro, comprimento, massa da matéria fresca, espessura do pericarpo, diametro da cavidade e teor de sólidos solúveis de fruto; e massa da matéria seca de folhas, caule, pecíolo e fruto. A condu o das plantas com maior número de folhas (tratamentos 1 e 2) proporcionou maior área foliar, massa da matéria seca de folhas, massa das matérias fresca e seca de fruto, espessura do pericarpo e sólidos solúveis de fruto, comparado aos tratamentos 3 e 4. Maior área foliar/fruto proporciona frutos com maiores massa, espessura de pericarpo e teor de sólidos solúveis. A fixa o do fruto na por o intermediária, comparada à fixa o no topo da planta, tem como vantagem o menor ciclo cultural. O meloeiro ajusta a produ o de massa dos órg os à área foliar disponível na planta. The study aimed to evaluate the effect of leaf number and fruit setting position in the plant on the production of biomass and fruit quality of melon Cantaloupe. The experiment consisted of four treatments, in a completely randomized design with 15 replications. The treatments were: 1) 14 leaves per plant, with the fruit set in the middle portion of the plant; 2) 14 leaves per plant, with fruit set in the top of the plant; 3) 14 leaves per plant until the fruit set on the top of the plant when seven leaves were immediately removed below the fruit and 4) 14 leaves per plant until the fruit set on top of the plant when seven leaves were removed from the plant base. The following traits were evaluated: leaf area; specific leaf area; leaf area ratio; days to harvest; cultural cycle; diameter, length, fresh matter, pulp thickness, cavity diameter and soluble solids content of the fruit; leaves, stem, petiole and fruit dry weight. The management of plants with higher leaf number (treatments 1 an

Species of Staphylococcus are common in hospital infection (HI). Methicillin resistant S. aureus (MRSA) has also become a serious problem in Brazilian HI. The aim of this study was to characterize the pathogenicity of methicillin-resistant S. aureus (MRSA) and methicillin-sensitive Staphylococcus aureus (MSSA) isolated in public hospitals. The clinical isolates were obtained from intensive care unit. The MRSA and MSSA strains were genotyped by PCR for detection genes related to virulence factors. Moreover, the strains were tested for biofilm formation and cytokine induction in macrophages. Three strains of MRSA (9.68%) expressed the Sea gene, one (3.23%) Seb, 17 (54.84%) Spa and seven (22.58%) had PVL. Two MSSA strains (2.98%) expressed the Sea gene, three (4.48%) Seb, 18 (26.87%) Spa and 11 (16.42%) showed positive results for the PVL gene. There was no expression of Sec and CflA between MRSA and MSSA strains. Among MRSA and MSSA isolates, none statistical differences were observed in biofilm production. The analysis of cytokine induction in the inflammatory response of J774 macrophages by MRSA and MSSA isolates did not show statistical difference. Understanding the mechanisms of pathogenesis of S. aureus could provide important clues for both preventing and treating infection caused by these organisms.

Abstract: there are reports of the use of cow urine in vegetable crops, but its efficacy needs to be confirmed. this work aimed to evaluate the effect of cow urine on the nutritional status of lettuce. the experiment consisted of 12 treatments arranged in a split-plot design and four randomized blocks. the ways of application (soil or foliar) were allocated in plots while the subplots consisted of solution concentrations (0.00; 0.25; 0.50; 0.75; 1.00 and 1.25 % v/v). it was applied 60 ml of solution/plant, divided into five applications of 5; 5; 10; 20 and 20 ml/plant, at 7, 14, 21, 28, and 35 days after transplant, respectively. the spad index was evaluated during the crop cycle. at harvest it was determined the head dry matter (hdm) and the contents of n, p, k, ca, mg, s, na, zn, fe, mn, cu and b in the dry matter of leaves (dml), stems (dms) and roots (dmr). for both ways of application, the spad index showed a linear increase in response to concentrations and a quadratic response over time. hdm presented a linear response to concentrations, with increasesof 25.9 and 35.4 % in the foliar and soil applications respectively. no effect of concentrations was observed on nutrient contents of dml and dms. for dmr, with soil application, there was a maximum point for p and k and minimum for fe and mn; na showed a linear increase in response to concentrations with foliar application. the effects of urinesolutions on lettuce growth may be caused by other factors than the amounts of nutrients present in the solutions.

Abstract: Objective: This study aimed to carry out a topographical analysis of frontal lobe executive function components in post-stroke patients. Methods: A descriptive, cross-sectional study. The assessment using the WCST (Wisconsin Card Sorting Test) included sixteen patients with a clinical diagnosis of CVA and frontal lobe impairment. Results from the two groups were compared (patients with right frontal lobe impairment and patients with left frontal lobe impairment). Statistical analysis was performed using the program “Statistical Package for Social Sciences” (SPSS) Version 20.0. For comparison between groups was used Mann-Whitney test and considered the alpha level of 0.05 on the statistically significant results. Results: There was no statistically significant difference between the groups, thus showing that executive functions are symmetrically distributed across the frontal lobes. Conclusion: Executive functions are symmetrically organized across the two frontal lobes, since the comparison between the groups did not demonstrate a statistically significant difference for any of the variables of WSCT.

Abstract: this study investigated the worries relating to physical appearance and the representative implications of an ideal body model, among fifty-three impoverished students, aged between thirteen and eighteen years. the field research was conducted over an eight-month period; participative observation and a questionnaire were used as data-gathering instruments; and the content analysis technique was used to code and interpret the information obtained. it was observed that the students attributed high value to their bodies, but they also demonstrated less rigid care and less aggressive interventions than expected, thereby revealing dispositions of civility that is not thought of, experienced and materialized homogeneously, but plurally.

Abstract: Nesse artigo apresento as considera es e análises presentes na pesquisa em processo, que realizo numa escola pública. Sua constitui o deve seu primeiro movimento àsmanifesta es de desconforto e homofobia com rela o a um grupo específico de três estudantes gays na comunidade escolar na qual atuo como professora. Percebo que a presen a desse grupo desacomoda o cotidiano escolar e desenvolvo minha argumenta o com base no potencial desestabilizador desses sujeitos, na inten o de pensar o impensável no currículo escolar. Esse trabalho parte da visibilidade de uma identidade sexual que foge à norma heterossexual e desafia a tendência normalizadora e homogeneizadora da educa o. A maneira como esse grupo gay se posiciona e constrói seus corpos cruza as fronteiras do masculino/feminino, desnaturalizando as identidadessexuais e de gênero que se baseiam em características biológicas e se apresentando como diferen a que escapa às classifica es binárias. Na constru o da pesquisa utilizo como referência o pensamento de Michel Foucault, especialmente com rela o à constru o histórica e discursiva de conceitos como sexualidade, identidade, diferen a enormalidade que têm servido para cria o e manuten o de padr es de conduta. Ao levar a problematiza o desses conceitos para o contexto escolar, considero produtiva a teoriza o queer para pensar a possibilidade de uma educa o n o heteronormativa, produtora de diferen as, que desconstrua identidades ao invés de tentar cristalizá-las. Abstract This article presents the considerations and analysis that make part of my research in process in a public school. The construction of this research dues its first move to viewsof discomfort and homofobia related to a specific group of three gay students in a school where I work as a teacher. I realize that the presence of that group disarrenges the school quotidian and I develop my argumentation on the unfixing potencial of those individuals, intending to think the unthinkable about the school curriculum. This work starts on the visibility of a sexual identity that runs away from the heterossexual rule and challenges the education tendency to normality. The way this gay group stands and constructs their bodies allow them to cross the borders of male/female, pointing out thenon-natural caracter of sexual and gender identities based on biology, presenting themselves as diference that scapes from binary classifications. One of the references of this research is the thinking of Michel Foucault, specially when talking about thehistorical and discursive construction of concepts

Abstract: The inserts from the selected clones were amplified by PCR with the universal oligonucleotide primers M13R and M13F. The obtained products were purified and fixed in duplicate on glass slides specific for use in DNA microarrays. The number of spots on the microarray totaled 6,144 and included 768 positive controls and 624 negative controls per slide. Validation of the platform was performed through hybridization of total DNA probes from XAC labeled with different fluorophores, Cy3 and Cy5. In this validation assay, 86% of all PCR products fixed on the glass slides were confirmed to present a hybridization signal greater than twice the standard deviation of the deviation of the global median signal-to-noise ration.Our validation of the XACArray platform using DNA-DNA hybridization revealed that it can be used to evaluate the expression of 2,365 individual CDSs from all major functional categories, which corresponds to 52.7% of the annotated CDSs of the XAC genome. As a proof of concept, we used this platform in a previously work to verify the absence of genomic regions that could not be detected by sequencing in related strains of Xanthomonas.Citrus canker, or cancrosis, is a disease that affects most species of the Citrus genus [1]. Its symptoms can be observed on leaves, fruits or branches and are characterized by small, pointed and spongy pustules that are surrounded by a chlorotic halo on both sides of the leaf. This halo tends to spread quickly through the tissue, increasing its diameter and becoming brownish or darker in color with a rough and salient appearance [2]. The causal agent of cancrosis is the bacterium Xanthomonas axonopodis pv. citri (XAC) [3], more recently renamed as Xanthomonas citri subsp. citri [4,5] whose genome was completely sequenced in 2002 [6] and compared with others organisms [6-8]. Data from this sequencing project revealed that the XAC genome contains a circular chromosome of 5.2 Mbp and two plasmids (33 and 64 Kbp), containing a tota
