The Echocardiography Quality Framework: a comprehensive, patient-centered approach to quality assurance and continuous service improvement
Authors: Masani Navroz
Published: October 2018

The Echocardiography Quality Framework (EQF) is a unique, comprehensive, holistic approach to improving all aspects of an echocardiography service. The EQF is a patientcentered program, combining Quality Assurance and Continuous Service Improvement. The framework encompasses measures of (i) the quality of echocardiography, (ii) reproducibility and consistency, (iii) education and training, and (iv) customer feedback. The EQF is scalable and adaptable to benefit any echocardiography service. A catalogue or library of supporting documents is being developed by the British Society of Echocardiography (BSE), to be made available to any participating department. A mechanism and online infrastructure for (optional) national registration or assessment is being developed, to be used as a standalone adjunct or linked to BSE Departmental Accreditation. The principles that underpin the EQF may be applied to other imaging disciplines and, ultimately, other medical or surgical specialties.
Evolução e elementos-chave do sistema de farmacovigilância do Brasil: uma revisão de escopo a partir da criação da Agência Nacional de Vigilância Sanitária
Authors: Mota Daniel Marques , Vigo Álvaro , Kuchenbecker Ricardo de Souza
Published: October 2018

Esta revisão de escopo objetiva descrever e caracterizar o sistema de farmacovigilância do Brasil (SINAF) e averiguar o atendimento aos requisitos mínimos propostos pela Organização Mundial da Saúde para um desempenho funcional de sistemas nacionais dessa natureza. A estratégia de pesquisa bibliográfica utilizou recomendações do STARLITE e termos de busca nas bases de dados MEDLINE/PubMed, Google, Imprensa Nacional e website da Agência Nacional de Vigilância Sanitária (Anvisa), compreendendo o período entre 1999, ano de criação da Anvisa, e março de 2016. Foram incluídas 47 (4,4%) publicações, de um total de 1.068 identificadas, prevalecendo, nesta ordem: 14 normas jurídicas (29,8%), 13 (27,6%) documentos técnicos e 10 (21,3%) artigos científicos. Os estudos e documentos técnicos analisados compreenderam a criação, em âmbito federal, da primeira unidade técnica de farmacovigilância do sistema de notificação de eventos adversos, o Centro Nacional de Monitorização e a Câmara Técnica de Medicamentos. A taxa de notificação de eventos adversos a medicamentos no Brasil correspondeu, em 2013, a 36 notificações/1 milhão de habitantes, bastante inferior à meta proposta na literatura internacional, que sugere 300 notificações/1 milhão de habitantes. Este estudo identificou aspectos estruturais e funcionais que podem comprometer o desempenho do SINAF, como a falta de legislação que institua oficialmente o próprio sistema e suas finalidades.
“Viver dignamente”: necessidades e demandas de saúde de homens trans em Salvador, Bahia, Brasil
Authors: Sousa Diogo , Iriart Jorge
Published: October 2018

Resumo: Este artigo discute as necessidades e demandas de saúde de homens trans, tema pouco estudado que, com frequência, interpela a construção de práticas de cuidado em saúde para esta população. Foi realizada uma pesquisa qualitativa composta de observação participante e entrevistas semiestruturadas com dez homens trans residentes em Salvador, Bahia, Brasil, em sua maioria negros, heterossexuais e com idades entre 20 e 43 anos. A análise foi baseada na antropologia interpretativa, articulada às críticas do pressuposto da interseccionalidade e da perspectiva decolonial. As necessidades e demandas de saúde dos homens trans são organizadas em três aspectos: a despatologização, a modificação corporal e os atendimentos ambulatoriais. Esses não são universais entre todos os homens trans e podem ser decorrentes de situações que assinalam conflitos e pressões grupais. A ausência do processo transexualizador no estado e as barreiras no acesso à rede de atenção à saúde intensificam o processo de mercantilização das suas demandas de saúde, em especial, as modificações corporais. Conclui-se que a transfobia estrutural faz disparar uma série de questões de saúde, ao mesmo tempo em que limita as possibilidades de obtenção de cuidado. A despatologização das vivências trans constitui o eixo central com base no qual o cuidado deve ser pensado, relacionando-a a mudanças culturais, políticas e sociais que impliquem a construção de uma sociedade não transfóbica e incidam no bem-estar e reconhecimento dos homens trans.

Bacteria belonging to Anaplasma, Ehrlichia, Rickettsia and Coxiella genera are considered emerging pathogens and livestock is one of the contexts where the transmission of these microorganisms can occur. The goal of this study was to determine serological evidence for the exposure to these bacteria in cattle and humans with occupational exposure to livestock in the subregions North and Magdalena Medio, Antioquia, Colombia, and to explore related factors. A cross-sectional study was conducted in 48 livestock farms distributed in six municipalities from both subregions: Belmira, Entrerríos and San Pedro de los Milagros (North), and Puerto Berrío, Puerto Nare and Puerto Triunfo (Magdalena Medio). Blood samples from 332 people and 384 bovines were evaluated by serology (IgM and IgG) screening for bacteria from the Anaplasma, Ehrlichia, Rickettsia, and Coxiella genera. Seropositivity in humans from both regions was 42.4% (95%CI: 31.2-55.1) for Anaplasma, 74.2% (95%CI: 66.0-84.4) for Ehrlichia, 72.5% (95%CI: 62.1-82.0) for Rickettsia, and 60.7% (95%CI: 59.7-69.1) for Coxiella burnetii. In cattle, seropositivity was 31.6% (95%CI: 19.9-44.2), 66.8% (95%CI: 55.2-78.1), 64.6% (95%CI: 53.8-74.5), and 61.6% (95%CI: 51.9-69.2), respectively. History of biting by ticks, milking, vaccination, having dogs and hens in the residence, as well as the consumption of raw milk derivatives were some factors associated with the infection by the bacteria studied. The results suggest a previous and recent exposure to these zoonotic bacteria genera in people with occupational exposure to livestock, as well as in cattle in the two studied subregions.

Published: October 2018

ABSTRACT: This report provides an unpublished account of an intra-abdominal myolipoma in a 11-year-old female Poodle with hyperadrenocorticism and diabetes mellitus. The patient was well controlled for both endocrine diseases; however, was suffering for severe abdominal discomfort. Ultrasound scan revealed a huge abdominal mass. At necropsy a pinkish mass (35cm x 28cm x 12cm) of elastic consistency attached to the broad ligament of the left uterine horn was reported. Histologically, this mass was constituted of a mixed population of well-differentiated adipocytes and of spindle-shaped mesenchymal cells. Both tumor cells were positive for vimentin at immunohistochemistry, while the spindle-shaped cells were positive for desmin and actin, compatible with smooth muscle cells. Immunohistochemistry was crucial for myolipoma characterization.
Uma vez mais, Sérgio e Gilberto Debates sobre o ensaísmo no suplemento literário do Diário de Notícias (1948-1953)
Authors: VENANCIO Giselle , WEGNER Robert
Published: October 2018

Resumo Aborda o debate estabelecido entre Sérgio Buarque e Gilberto Freyre, reconhecidos como ensaístas nos anos 1930, e a forma como se posicionaram sobre o tema no suplemento literário do Diário de Notícias. De uma parte, Holanda reverbera os debates desenvolvidos nos meios universitários e se alinha em defesa dos estudos acadêmicos, com o argumento de que eles renovavam a vida intelectual do país e rompiam com o ensaísmo. Por outro lado, ao defender seu projeto intelectual inaugurado com Casa Grande & Senzala, Freyre prossegue defendendo a forma ensaística como um padrão de cientificidade legítimo, bem como sugere que ela poderia inclusive renovar os estudos acadêmicos realizados em outros países. O artigo investiga o debate de modo a reconstruir as formas que ele ganhou no seu presente, buscando elaborar uma reconstrução genealógica da categoria ensaio exatamente no momento em que se constituía em critério de classificação negativo das narrativas sobre o Brasil.
Aventuras e estratégias da razão Sobre a historicização da epistemologia na França
Authors: ALMEIDA Tiago Santos
Published: October 2018

Resumo A “História da Ciência” nasceu como gênero literário no século XVIII, como expressão máxima do pensamento moderno, tematizado na doutrina da perfectibilidade da Razão e na confiança no progresso das ciências. Bem diferente é o reconhecimento do fato de que cada ciência particular possui uma temporalidade e uma história que lhes são próprias, ideia que emerge nas primeiras décadas do século XX, como resultado de um movimento conhecido como “historicização da epistemologia”, executado por diferentes tradições filosóficas europeias. Nossa intenção é mostrar como, na França, a emergência da ideia de “história das ciências” (no plural, como algo diferente do gênero “História da Ciência”) está relacionada à superação, por Gaston Bachelard, de certos aspectos da filosofia de Kant, notadamente no que diz respeito à capacidade de formação histórica dos critérios de racionalidade das diferentes ciências.

Published: October 2018

ABSTRACT Objective: to analyze the sexual behavior of the female partners of inmates and estimate the prevalence of sexually transmitted diseases. Method: cross-sectional, quantitative study involving 349 female partners of inmates. The Estudo de Comportamento Sexual [Sexual Behavior Study], an instrument validated in Brazil, was used to collect the data. The Statistical Package for the Social Sciences, version 20 was used in the statistical analysis. Results: 41.2% of the female partners of inmates reported a prior history of sexually transmitted disease. Association was found between having more than one partner in the last 12 months (<0.006), sexual violence (<0.001), having sex for money (<0.001), under the influence of alcohol (<0.001), and under the influence of drugs (<0.005). The variables associated with sexually transmitted infections in the logistic regression were: having more than one partner in the last 12 months, sexual violence, sex for money, and under the effect of alcohol or drugs. Conclusion: The number of partners, sexual violence, sex for money, and under the influence of alcohol or drugs are sexual risk behaviors that increase the prevalence of sexually transmitted infections among the female partners of inmates.

Published: October 2018

ABSTRACT Objective: to verify the association between the prognostic scores and the quality of life of candidates for heart transplantation. Method: a descriptive cross-sectional study with a convenience sample of 32 outpatients applying to heart transplantation. The prognosis was rated by the Heart Failure Survival Score (HFSS) and the Seattle Heart Failure Model (SHFM); and the quality of life by the Minnesota Living With Heart Failure Questionnaire (MLHFQ) and the Kansas City Cardiomyopathy Questionnaire (KCCQ). The Pearson correlation test was applied. Results: the correlations found between general quality of life scores and prognostic scores were (HFSS/MLHFQ r = 0.21), (SHFM/MLHFQ r = 0.09), (HFSS/KCCQ r = -0.02), (SHFM/KCCQ r = -0.20). Conclusion: the weak correlation between the prognostic and quality of life scores suggests a lack of association between the measures, i.e., worse prognosis does not mean worse quality of life and the same statement is true in the opposite direction.

Authors: Wilson Ana Maria Miranda Martins , Peterlini Maria Angélica Sorgini , Pedreira Mavilde da Luz Gonçalves
Published: October 2018

ABSTRACT Objective: To evaluate the hemolysis biomarkers of packed red blood cells transfused by two different linear peristaltic infusion pumps at two infusion rates. Method: An experimental and randomized study was designed simulating the clinical practice of transfusion. Two linear peristaltic infusion pumps from different manufactures were studied in triplicate at 100 mL/h and 300mL/h infusion rates. The chosen hemolysis biomarkers were total hemoglobin, free hemoglobin, hematocrit, potassium and degree of hemolysis. They were analyzed before and after each infusion. Results: Potassium showed statistically significant variations in all scenarios of the experiment (P<0.010). In a separated analysis, potassium increased mainly at 300mL/h rate (P=0.021) and free hemoglobin had significant variation when comparing infusion pumps from different manufacturers (P=0.026). Although hematocrit, total hemoglobin and degree of hemolysis had increased after infusion, no statistically significance variations were identified. Conclusions: Hemolysis risk induced by a linear peristaltic infusion pump was identified by an increase in free hemoglobin and potassium markers. As the potassium biomarker is often increased in aged packed red blood cells, we do not recommend using them in this scenario. Additional studies should be performed about other markers and using larger samples in order to reinforce the transfusion practice in nursing.
Floristic and structure of the arboreal community of an Ombrophilous Dense Forest at 800 m above sea level, in Ubatuba/SP, Brazil
Authors: Souza Ana Cláudia Oliveira de , Benacci Luís , Joly Carlos Alfredo
Published: October 2018

Abstract: Undoubtedly, the publication of floristic lists and phytosociological studies are important tools for metadata generation, quantification and characterization of the megadiversity of Brazilian forests. In this sense, this work had the objective of describing the composition and the structure of the tree community of one hectare of Dense Atlantic Rainforest, at an altitude of 800 m. All individuals, including trees, palm trees, arborescent ferns and dead and standing stems, with a diameter at breast height (DBH) of ≥ 4.8 cm were sampled. After the identification of the botanical material, we proceeded to calculate the usual phytosociological parameters, besides the Shannon diversity index (H') and Pielou equability index (J). A total of 1.791 individuals were sampled, of which 1.729 were alive, belonging to 185 species, 100 genera and 46 families. The results obtained showed a strong similarity of structure and floristic composition with plots of both Montana and Sub Montana Ombrophilous Dense Forest studied in the same region. This reinforces the hypothesis that the transition between the phytophysiognomies of the Atlantic Ombrophylous Dense Forest is gradual, and that the boundaries between them cannot be clearly established.

ABSTRACT In order to evaluate the effect of irrigation water salinity in interaction with different potassium and calcium ratios applied through fertigation in eggplant, an experiment was carried out at the Department of Environmental and Technological Sciences of the Federal Rural University of the Semi-Arid Region, in Mossoró, RN, Brazil. The experimental design was randomized blocks, in a 5 x 4 factorial scheme, with four replicates. The treatments were obtained by the combination between five ionic ratios of potassium and calcium (F1 = 4.2/1; F2 = 3.5/1; F3 = 2.8/1; F4 = 2.2/1; F5 = 1.8/1) and four levels of irrigation water salinity (S1 – 0.5; S2 – 2.0; S3 – 3.5; and S4 – 5.0 dS m-1). The following variables were evaluated: number of fruits per plant, fruit length, fruit diameter, fruit fresh weight and yield. Yield, fruit length, fruit fresh weight and number of fruits decreased with the increase of salinity in all the treatments. Salinity significantly affected fruit diameter, which increased only under fertigation with potassium-rich solutions.

Published: October 2018

Resumo A introdução de diferentes linhagens de microrganismos nas fermentações destinadas à produção de cachaça, decorrente das alimentações sucessivas de caldo, pode contribuir com o desenvolvimento de diferentes classes de microrganismos, comprometendo a atividade metabólica das leveduras e a condução do processo fermentativo. Assim, o objetivo do presente estudo foi avaliar a influência do tratamento térmico do caldo de cana nas características tecnológicas e microbiológicas do substrato, e os seus reflexos na condução do processo fermentativo e na qualidade química da cachaça. Para tanto, o caldo foi submetido a tratamento térmico à temperatura de 90°C por 5 minutos, para então serem quantificadas as concentrações de bactérias láticas, leveduras totais e leveduras não Saccharomyces . As fermentações foram conduzidas em cinco ciclos fermentativos, utilizando-se mosto de caldo de cana tratado e não tratado termicamente. O processo foi monitorado por meio das análises de viabilidade celular e de brotos, e do índice de brotamento, enquanto as populações de leveduras totais e não Saccharomyces foram quantificadas no fermento reciclado. Ao término das fermentações, foram determinados o pH, a acidez total titulável, o teor alcoólico e os açúcares redutores residuais totais dos vinhos, sendo estes destilados em alambique de cobre para a quantificação da composição química da cachaça. O tratamento térmico possibilitou a inativação dos microrganismos do caldo, sem comprometer as suas características físico-químicas. A viabilidade celular foi reduzida para as fermentações conduzidas com caldo não tratado termicamente, porém as características físico-químicas dos vinhos não foram afetadas. Os destilados provenientes de fermentações conduzidas com caldo não tratado apresentaram maiores níveis de acidez volátil e ésteres, ao final do quinto ciclo. As concentrações de álcoois superiores e furfural foram elevadas para ambos os tratamentos no primeiro e quinto ciclo, respectivamente.
Systematics of Clupeiformes and testing for ecological limits on species richness in a trans-marine/freshwater clade
Authors: Bloom Devin D. , Egan Joshua P.
Published: October 2018

ABSTRACT Clupeiformes (herring, sardines, shad, anchovies and allies) are a globally distributed clade with nearly 400 marine, freshwater, and diadromous species. Although best known as filter feeding fishes that form large schools, this group occupies a diverse array of trophic guilds and habitats. Theory suggests that species richness in clades is modulated by ecological limits, which results in diversity-dependent clade growth, a pattern that most clades exhibit. As a trans-marine/freshwater clade that has undergone repeated transitions between marine and freshwaters, Clupeiformes are an excellent system for investigating the interplay between ecological diversity and macroevolutionary dynamics. In this study we review the systematics of Clupeiformes and explore discordance in phylogenetic relationships and divergence times between mitochondrial and nuclear loci. We then use comparative methods to test whether ecological limits regulate diversity in Clupeiformes. We find discordance in phylogenetic relationships at various taxonomic scales, but also considerable agreement between genomes. Our results suggest that trans-marine/freshwater clades are able to circumvent ecological limits on clade growth at regional, but not on local scales. Our study demonstrates that phylogenies are a critical link between ecology and macroevolutionary dynamics, and suggests habitat transitions can play a key role in shaping diversity patterns, particularly in the neotropics.

Published: October 2018

Abstract Objective: To describe the frequency of albuminuria in overweight and obese children and adolescents and to relate it to the severity of obesity, pubertal staging, associated morbidities and the glomerular filtration rate. Method: Cross-sectional study including 64 overweight and obese children and adolescents between 5 and 19 years of age. Data collected: weight, height, waist circumference and systemic arterial pressure. Laboratory tests: lipid profile; glycemia and insulin, used to calculate the Homeostasis Model Assessment (HOMA-IR); C-reactive protein; glutamic-pyruvic transaminase and albuminuria in an isolated urine sample (cutoff <30 mg/g). Creatinine was used to calculate the estimated glomerular filtration rate (eGFR, mL/min/1.73 m2). Results: The mean age was 11.6 ± 3.4 years, 32 (50%) and 29 (45.3%) were male and prepubertal. Forty-six (71.9%) had severe obesity. The frequency and median (min/max) of the observed values for albuminuria (> 30 mg/g) were 14 (21.9%) and 9.4 mg/g (0.70, -300.7 mg/g). The mean eGFR was 122.9 ± 24.7 mL/min/1.73 m2. There was no significant correlation between body mass index, pubertal staging, insulin and HOMA-IR with albuminuria values and neither with eGFR. Children with albuminuria tended to have higher values of diastolic blood pressure (75.0 ± 12.2 vs. 68.1 ± 12.4, p = 0.071). Conclusion: Albuminuria, although frequent in children and adolescents with obesity, was not associated with other morbidities and the glomerular filtration rate in these patients.

Abstract Hemophagocytic lymphohistiocytosis (HLH) is an uncommon and life-threating condition characterized by major immune activation and massive cytokine production by mononuclear inflammatory cells, due to defects in cytotoxic lymphocyte function. It is even more unusual in renal transplant recipients, in which it is often associated with uncontrolled infection. The mortality is high in HLH and differential diagnosis with sepsis is a challenge. The approach and management depend on the underlying trigger and comorbidities. We report a case of a 50-year-old renal transplant female admitted with fever and malaise 3 months post-transplant and presenting anemia, fever, hypertriglyceridemia, high levels of serum ferritin, and positive CMV antigenemia. Urine was positive for decoy cells and BKV-DNA. Graft biopsy showed CMV nephritis. Both blood and urine cultures where positive for E. coli. Hemophagocytosis was confirmed by bone marrow aspiration. Immunosuppression was reduced, and the patient received high-dose intravenous immunoglobulin and dexamethasone, with complete response after 3 weeks. We highlight the importance of early diagnosis and proper management of a rare and serious condition in a renal transplant patient, which can allow a favorable clinical course and improve survival rate.

Published: October 2018

Abstract: The packaging, used to maintain the seeds during storage, is extremely important in their conservation. Seeds from the cultivar BAT 2101 were used in order to evaluate the effect of packaging on the conservation of the quality of bare and pelleted tobacco seeds stored in the long-term. After characterization of the lot profile, the seeds were stored for 180, 360, 540, and 720 days under ambient conditions at 25 °C ± 2 and 62.8% relative humidity in cotton bags, aluminum cans, laminated envelopes, plastic envelopes and paper envelopes. The seed quality throughout the storage in the different packages was determined by the water content and germination tests, first germination count, germination speed index, initial and final emergence and emergence speed index. The aluminum can packaging keeps the quality of bare and pelleted tobacco seeds for a period of 720 days. Up to 360 days of storage, there was a decrease in the dormancy of bare and pelleted seeds with an increase in deterioration after this period, except for those kept in the aluminum can packing.

Published: October 2018

ABSTRACT: Synergism is a desired result in the interaction between herbicides because it provides many benefits, among which the reduction of doses and the increment of control efficiency, and because it positively signals for the joint application of herbicides. The objective of this study is to evaluate the effect of the association of saflufenacil with other herbicides that promote oxidative stress on the development of Euphorbia heterophylla as well as to analyze if the resulting interactions are antagonistic, additive or synergistic. The experiment was conducted in pots, in a greenhouse, using a completely randomized design with four replications. Treatments consisted of saflufenacil (0, 1,2, 2,32, 4,47, 8,63, 16,65 g ha-1) alone and associated with clomazone (288 and 504 g ha-1), metribuzin (105.6 and 206.4 g ha-1) and paraquat (20 and 40 g ha-1), as well as these herbicides applied alone at the same doses described above. Twenty-one days after the application (DAA), the shoot dry matter (SDM) of plants was evaluated in each experimental unit. The Limpel-Colby method was used to calculate the expected response of the herbicide interaction. All combinations of saflufenacil with clomazone, metribuzin and paraquat were considered synergistic. Among the treatments associated with saflufenacil, those including metribuzin at the dose of 105.6 g ha-1 were the ones that provided the most promising results, which stood out for the greater reductions of wild poinsettia shoot dry matter, compared to the application of saflufenacil alone.
Defoliation and S nutrition on radish: growth, polyphenols and antiradical activity
Authors: Stagnari Fabio , Galieni Angelica , D’Egidio Sara , Pagnani Giancarlo , Ficcadenti Nadia , Pisante Michele
Published: October 2018

ABSTRACT Experiments were carried out to study patterns of artificial defoliation in radish in combination with sulphur (S) fertilization, to evaluate the contribution of younger and older leaves on plant growth and phenolics accumulation in storage roots. Biomass accumulation and partitioning were related to leaf age, magnitude and timing of the clipping treatments. Older leaves increased biomass production and translocation into the storage organ; besides, they induced higher accumulation of phenolic compounds compared to the younger leaves. The highest S fertilization rate (120 kg ha-1) significantly enhanced the polyphenols accumulation, as well as the antiradical activity. The modulation of S inputs in combination with slightly induced stress from defoliation could effectively enhance the concentration of some important phytochemicals, providing higher nutritionally improved vegetables, without affecting yield.
Phenological and physicochemical properties of Pereskia aculeata during cultivation in south Brazil
Authors: Silva Débora O , Seifert Maurício , Schiedeck Gustavo , Dode Juliana S , Nora Leonardo
Published: October 2018

ABSTRACT Pereskia aculeata, known as ora-pro-nobis in Brazil, is native from tropical dry forests. This Cactaceae plant possesses succulent and edible leaves, which contain high amounts of protein, minerals, vitamins and fiber. Nutritional properties and ability to grow under limited water supply of ora-pro-nobis are known, but little information is available about the growth behavior and nutritional composition of this plant when cultivated under temperate humid climate. Therefore, we evaluated the phenology of the plant, including observation of new leaves, flowering, fruiting and relating it with the climate changes. Also, we analyzed some physicochemical characteristics (humidity, leaf area, height, protein, color, total phenolic content and antioxidant activity) of ora-pro-nobis cultivated in Pelotas, Rio Grande do Sul, Brazil. We observed that ora-pro-nobis developed normally, but with a quiescent state in the winter, without producing leaves. Flowering of the plant started in March and the fructification started one month later. All physicochemical characteristics varied through the period of cultivation. Our findings support that cultivation of ora-pro-nobis for production of leaves is feasible under temperate and humid climate.

ABSTRACT Studies on nutrient uptake are important to understand nutritional needs of crops, which demand may also be influenced by fertilization management, particularly P fertilization. Thus, the aim of this study was to evaluate macronutrient accumulation and distribution in watermelon cv. Magnum, under two forms of phosphate fertilization. The experiment was carried out in a sandy-textured Argisol in Mossoró-RN. The experimental design was a randomized block design, arranged in split plot in time, with four replicates. We evaluated dose of 137 kg ha-1 of P2O5 under two forms of fertilization [pre-planting (F0) and pre-planting + topdressing (F1)]. Triple superphosphate (SFT) was used for pre-planting applications and topdressing applications were done through fertigation using monoammonium phosphate (MAP, 34 kg ha-1 of P2O5). Shoot samples (stem + leaf + fruit) of the experimental plots were collected at 27, 34, 40 and 55 days after emergence (DAE), and quantitative values of the accumulated nutrients were determined. In general, the highest accumulation of macronutrients occurred in the last third of the crop cycle. General accumulation of macronutrient was altered by fertilization form. An increase in P accumulation was observed using F1 fertilization, both in total and in fruits. Macronutrient accumulation rates increased during the evaluation period, except for Ca and Mg in F1 fertilization. F1 fertilization provided higher total accumulations of Ca and Mg, but the same did not occur for the accumulation in fruits.

ABSTRACT Gas exchanges in species and interspecific hybrids of tomato in different environments may contribute to the development and selection of genotypes with a higher tolerance to adverse cultivation conditions. This study aimed to assess the photosynthetic characteristics of wild tomato species and the cultivar Redenção, as well as the respective F1 hybrids of interspecific crosses cultivated under two environments. The experimental design was a randomized block design with three replications and the assessment of six wild accessions, one cultivar, and the respective interspecific hybrids under two environments. At 14, 28, 42, 56, and 70 days after transplanting (DAT), gas exchange characteristics were assessed by means of a portable photosynthesis measurement system. The stomatal density of abaxial and adaxial surfaces of first-order leaflets was estimated under a protected cultivation at 56 DAT. We observed a higher influence of wild tomato species and interspecific hybrids on the assessed characteristics when compared to the cultivation environments. The accession ‘LA-716’ and the hybrid ‘Redenção’ × ‘LA-716’ presented the highest water use efficiency and the accessions ‘PI-127826’ and ‘PI-134417’ and the interspecific hybrids ‘Redenção’ × ‘PI-127826’ and ‘Redenção’ × ‘PI-134417’ presented the highest values of CO2 assimilation, transpiration, instantaneous in vivo carboxylation efficiency of Rubisco, and number of stomata on the abaxial leaflet surface. Thus, the descendants of Solanum habrochaites are an interesting alternative to breeding programs that aim to make advances in obtaining strains that exhibit improvement in their photosynthetic characteristics.
The Economist and Human Rights Violations in Brazil During the Military Dictatorship

Published: October 2018

Abstract The purpose of this article is to analyse British media coverage of the Brazilian dictatorship. Specifically, we examine coverage by the weekly news magazine The Economist in the period from the promulgation of Institutional Act 5 in December 1968, to 1975, the second year of the Geisel administration. We compare its coverage with that of The Times and The Guardian in order to reach an understanding of its portrayal of Brazil in terms of two themes in particular: economic performance (notably the ‘Brazilian miracle’), and political repression. We relate the latter theme to the international condemnations of torture, and the disappearance of political prisoners. Furthermore, given that The Economist mainly covers issues from an economic perspective, we examine shifts in the frequency and content of articles about Brazil, and conclude that The Economist’s portrayal of Brazil in the period under review deviated from that of much of the rest of the British Press.

Resumo O monitoramento do desempenho de projetos por meio de indicadores é um recurso de gestão de grande importância para as organizações, sendo amplamente utilizado o Earned Value Management (EVM). Entretanto, há poucas pesquisas quantitativas que comparam o modelo teórico do valor agregado com a utilização prática na indústria da construção civil no Brasil. Outrossim, alguns autores argumentam que a fundamentação teórica do EVM é utilizada de forma equivocada na construção civil. O presente artigo tem como objetivos principais verificar se os usuários identificam benefícios na utilização do EVM e analisar os fatores críticos de sucesso, limitações e a utilização de acordo com o perfil dos usuários por meio de uma pesquisa quantitativa. A pesquisa foi realizada por meio de questionário do tipo Survey disponibilizado pela internet, tendo tido 106 respondentes entre gerentes e técnicos de planejamento da construção civil. Foi verificado que os dados obtidos na pesquisa se mostraram satisfatórios e validados, com estatísticas adequadas de Alfa de Cronbach e testes de análise fatorial de Kaiser-Meyer-Olkin. Os resultados demonstraram que os respondentes identificaram benefícios na utilização do EVM, apesar de ainda utilizarem o valor agregado de maneira parcial.

Abstract Considering the growing of chronic non-communicable diseases worldwide, many studies have pointed out the role of the built environment as a support for walking. These studies are being applied in metropolitan and county regions or in specific areas of larger citiesof developed countries. Nevertheless, there is noevidences of the application of the walkability index in an entire Brazilian city. The main objective of this study is to understand walkable areas in a Brazilian medium sized city such as Cambé - PR, based on the walkability variables defined by Frank et al. (2010). The index systematizes four built environment variables: net residential density, retail floor area ratio, intersection density and land use mix. The results show that higher walkability areas are located in downtown and in three areas in the outskirts of Cambé, which were formerly designed to attend social housing projects. The transformations of land use mix and the urban layout characteristics of these areas improved the walkability level. This paper contributes to enlighten the characteristics of walkable areas and highlights a different outcome when considering a city of a developing country such as Brazil.

Peer tutoring is a form of structured peer learning technique. This study develops and tests a new form of peer tutoring technique, ‘Interdependent Cross-Age Peer Tutoring’ (ICAT). The method is informed by the ‘what works literature’ within peer tutoring and brings together crucial elements which have been shown to provide high effect sizes. Specifically, ICAT consists of an autonomous/informative structure, with students setting their goals in a cross age peer tutoring mathematics context. ICAT was implemented for six weeks in three different schools across England, with teachers concentrating on teaching their planed topics. School A (n=95) Year 8 students tutored Year 6, school B (n=65) Year 9 tutored Year 7, and school C (n=44) Year 10 students tutored year 8. Schools A and B adopt a pre/post-test quasi-experimental design and school C adopts a single group pre/post-test design. Research made instrument were applied to measure tutees performance gains. Classroom and paired observation were conducted for each school and the ICAT lesson materials for the six weeks were analysed to establish intervention fidelity. School A showed the highest ICAT implementation and effect size, 0.92, significant at (p

Pragmatics of Crisis-Motivated Humour in Computer Mediated Platforms in Nigeria
Authors: Akinola Ayodele James
Published: October 2018

Humour, an established means of releasing stress and tension has attracted scholarly attention over the years. In the Nigerian discourse context, studies on Crisis-Motivated Humour (CMH) via CMC platforms are scanty. This paper investigates humour shared through the social media which reflects the socioeconomic/political challenges in Nigeria in order to identify CMH as a form of humour through which real-life experiences of other people can be understood. Ethnography of Communication and Pragmatic act theory serve as the theoretical framework. Ten anonymous humorous compositions were randomly selected from WhatsApp and Facebook. CMH is a creative composition of jokes which reflects the Nigerians’ experiences, perceptions, imaginations and assumptions. They are purposefully composed by Nigerians, in order to downplay the effects of the crisis and bring temporary reliefs to the audience. These jokes elicit amusement, high-level wits and satirise the crisis situation(s). CMH are composed mainly in English with a blend of pidgin and a reflection of some Nigerianism. They are replete with verifiable, but exaggerated facts deployed through varying practs. Use of the first person singular pronoun ‘I’ and second person singular/plural ‘you’ with the use of simple present tense of verb among other grammatical elements, are a norm. All these make some of the jokes believable and also establish CMH as a unique genre of humour with an unlimited audience. CMH are often preserve-able and re-usable and thus serve as a relevant medium through which political leaders can assess the plights of the populace and access first-hand information on the ‘real’ impacts of the crisis.
