Teoría política y fundamentos del poder real en el Virreinato del Perú ( siglos XVI - XIX)
Authors: Morales Cerón Carlos
Published: April 2019

El presente trabajo de índole teórica, tiene por finalidad explicar los fundamentos del poder practicados durante el Perú colonial desentrañando los fundamentos teóricos con los que fueron explicados y racionalizados. La lógica del poder imperial y virreinal fue racionalizada principalmente por juristas y tratadistas del derecho español y destacados exponentes de la teología moral. Asimismo, se hace mención de los mecanismos empleados por los virreyes para poder legitimarse ante el estado civil y religioso y ante la plebe urbano rural.
San Jose de Quiruvilca - Origen y vicisitudes de un asiento minero
Authors: Espinoza Soriano Waldermar
Published: April 2019

En el año 1629 comenzaron las explotaciones mineras en el cerro de Quiruvilca, sierra del departamento de La Libertad, pero la veta grande fue descubierta y trabajada desde 1634, gracias a la constancia de Fernando de Ahedo y Sara+via, fundador del asiento minero, quien le puso el nombre de San José de Quiruvilca. Desde un principio bracearon trabajadores que nunca fueron compelidos a mitas. Produjo plata de buena ley. Fue visitada por Martínez Compañón, obispo humanista de la era borbónica. Tuvo un régimen laboral acorde a las costumbres de los siglos xvii al xix. En el xx pasó al control de empresas transnacionales que además de plata, extraen otros metales. Perdura hasta hoy, tiempo durante el cual ha dado origen a una amplia población humana que vive en un enorme asentamiento urbano.

Authors: Chuspe Apaza Keyko , Ñañez Campos Cristhian , Benites Bonifacio Óscar , Soria Núñez Carmen
Published: April 2019

El presente documento es el resultado de un trabajo de investigación/acción grupal que busca examinar las dinámicas de producción y comercialización desenvueltas en la Bioferia de Miraflores, en la ciudad de Lima. Hace énfasis en cuatro aspectos: Su historia (memoria de la experiencia), la relación interna (tipo de organización), relación externa (con el entorno de la Bioferia) y la proyección que tiene la Bioferia a mediano y largo plazo. En el transcurso del examen se va a poder conocer y encontrar elementos propios de las economías sociales y solidarias, llamando la atención este tipo de desarrollo, que busca ubicarse fuera de la lógica neoliberal de mercado y se plantea como una alternativa a tomarse en cuenta dentro de la racionalidad capitalista en la que estamos inmersos incluso en lo que respecta a la academia. Este examen permite continuar discutiendo sobre las economías sociales y solidarias como una alternativa de producción a la impuesta desde el libre mercado. Así como conocer racionalidades distintas que parten de la producción económica como el tipo de organización que esta demanda, siendo en este caso la soberanía alimentaria y la comercialización ecológica en función de productos orgánicos, lo necesario a rescatar.
Adolescencia y juventud: reposicionamientos teóricos
Authors: Urteaga Castro-Pozo Maritza
Published: April 2019

Entre finales del siglo xix y los albores del xx, el conocimiento científico sobre los jóvenes se acentúo bajo la tríada teórica «biológicamédica- psicológica» y marcó un escenario importante para la disputa entre posturas epistémicas diferentes, las cuales manifestaron representaciones divergentes del término juventud y adolescencia. Si bien ambos términos siguen usándose indistintamente, son conceptos que provienen de dos formas de mirar a los jóvenes y proponen abordajes e interpretaciones distintas a sus problemáticas. El objetivo del texto es marcar la trayectoria divergente de ambos conceptos, rastrear su genealogía e ingresar al régimen de verdad que sustenta las representaciones, prácticas institucionales y el sentido común de la población hacia los jóvenes del siglo xxi. Se discuten los problemas que estas nociones plantean al registro e interpretación de las conductas juveniles contemporáneas frente al último gran cambio en el régimen de referencia social y se exponen dos casos de estudio de segmentos de la juventud mexicana para ilustrar las dificultades y las posibles salidas teóricas al impasse actual entre teoría y realidad.
Área de vida de la especia invasora Achatina fulica Browdich, 1822 (Gastropoda: Achatinidae) en un área de conservación de bosque seco ecuatoriano
Authors: Cuasapaz-Sarabia Jessica , Salas Jaime Antonio
Published: April 2019

Achatina fulica es un gasterópodo terrestre invasivo, conocido como una de las 100 especies invasoras más dañinas del mundo, el cual arribó a Ecuador hace 10 años, pero no se ha evaluado aún su impacto sobre los ecosistemas nativos. El objetivo principal fue determinar el área de vida (AV) promedio de esta especie en dos zonas con distinto grado de intervención en el Bosque Protector Cerro Blanco, un remanente de bosque seco tropical. La fase de campo consistió en la captura, marcaje, recaptura, toma de medidas morfométricas y georreferenciación de los individuos; para el análisis de datos se calculó el AV mediante el polígono convexo, y se lo correlacionó con variables ambientales a través de un análisis de componentes principales (ACP). El AV promedio en la zona alterada fue de 3,58 m2 (±0,93; n=30), y en el sendero ecoturístico fue 3,27 m2 (±0,48; n=40); se determinó que la humedad fue el parámetro ambiental que influyó directamente sobre el AV y la densidad poblacional en ambas zonas de estudio. El manejo de esta especie invasora no consta como un asunto clave de manejo para esta reserva privada, por lo que se recomienda ejecutar acciones de control para su erradicación

Published: April 2019

Prosopis pallida forma parte de los algarrobales del desierto de Sechura en el noroeste peruano. Brinda múltiples beneficios como recurso para la fauna silvestre. Siguiendo el concepto de selección de recursos, se plantea como objetivo determinar el uso y selección de las partes aéreas de P. pallida por parte de reptiles, aves y mamíferos, en el algarrobal aledaño a la laguna Ñapique (Sechura, Perú). Los datos se tomaron en seis transectos seleccionados convenientemente y se calculó la disponibilidad del árbol después de dividirlo en tres componentes, copa superior, copa inferior y tronco con ramas, a los que se añadió la sombra bajo la copa como cuarto componente por estar relacionado directamente con el árbol. Se adaptó el diseño Tipo I de Manly (la disponibilidad y uso se estiman para todos los individuos de la especie dentro del área de estudio) y se usó el Cociente de Selección de Manly para determinar la selección de los componentes del árbol por parte de la fauna. Los reptiles seleccionaron la sombra bajo la copa. Las aves y mamíferos seleccionaron el tronco y ramas. El uso y selección de los diferentes componentes de P. pallida revelan la vital importancia que tiene para la sobrevivencia de la fauna silvestre en el desierto de Sechura.

[full article and abstract in Lithuanian; abstract in English]
This article presents theoretical and empirical research that aims to analyze the techniques for increasing audience engagement in celebrity communication. It was discussed which part of the followers across social networks could be defined as the fans of a given celebrity. The paper discusses the identification of the fans among the total fol­lowers of a celebrity. In discussing the patterns of follower engagement, the aspects of emotional connectivity should be emphasized: warm appeals to followers, questions for the mutual discussions, provocations, hints, and intrigues, all utilized in order to pique the audience’s curiosity, asking opinions on various issues, publishing motivational, inspirational stories, giving presents, organization of contests, thanks for being together at concerts and giving support, compliments to supporters, etc. In addition to the emotional value, it is possible to highlight a practical value of the celebrity’s announcements to their followers in terms of job offers, opportunities for participation in video shoots, the sharing of concessions, invitations to events, closed parties, etc.
The empirical research has revealed that the followers are not necessarily the fans of celebrities. In analyzing the feedback of the followers, certain groups become particularly obvious: fans, non-fans, and anti-fans, as stated by J. Grey. Not only constructive statements can be seen in the comments section, but also objections to the position expressed by the celebrity, and even extremely negative feedback (those who are questioning the celebrity’s tal­ent, morality, popularity, etc.). Fans obviously are the most active part of the followers, who mostly respond to the celebrity’s messages. They are characterized by their active participation in contests, constant commentaries, open and sincere admiration of the celebrity and all they have done, strong support in all of their decisions, resentment expressed regarding any unfriendly comments, often acting as a defensive shield against the unfriendly followers.
Fans actively follow the celebrities’ lives, welcoming the various personal, national, and state celebrations, express­ing their joy in the new stage of activity and achievements, demonstrating a deeper knowledge of past work and previous achievements, incorporating celebrity-created photoclays that exaggerate the strengths of the celebrities.
Is there a correlation between depressive symptoms and motor skills in post-stroke patients?
Authors: Yoshida Hélio Mamoru , Lima Fabrício Oliveira , Barreira Júlia , Appenzeller Simone , Fernandes Paula Teixeira
Published: April 2019

ABSTRACT Deficits in motor skills and depressive symptoms are common effects observed after stroke, so it is necessary to understand how these variables interact with each other. Therefore, the aim of this study was to investigate the relationship between these two variables in post-ischemic stroke patients. We evaluated 135 patients with a mean age of 60 years (± 15). The Fugl-Meyer assessment of motor function was used to assess motor skills in the upper limbs, lower limbs, balance, and sensitivity and the Beck Depression Inventory was applied to evaluate depressive symptoms. To assess the relationship between both components, Spearman's correlation was performed. Depressive symptoms were negatively correlated with all variables of motor skills. This study suggests that higher motor skills in post-stroke patients may be associated with fewer depressive symptoms. Thus, a better understanding of how post-stroke symptoms are interrelated may improve patient treatment and care, contributing to a better quality of life.
Constipation is associated with tension type headache in women
Authors: Ozan Zeynep Tugba , Tanik Nermin , Inan Levent Ertugrul
Published: April 2019

ABSTRACT Tension-type headaches (TTH) and irritable bowel syndrome (IBS) are comorbid diseases affecting, especially, women. One of the underlying mechanisms for both is autonomic dysfunction in the brain-gut axis. We aimed to evaluate the factors accompanying TTH and their relation to functional gastrointestinal disorders. Methods: Women diagnosed with TTH were questioned about headache pattern and severity, and accompanying factors, as well as being screened for IBS according to the Rome III criteria. The participants were divided into two groups: constipation-dominant IBS (IBS-C) group and “others”, with a total of 115 individuals included in the study. Results: Of the 115 patients; 48 (41.8%) of the women had IBS-C criteria while 67 (58.2%) described mixed-type IBS or diarrhea-dominant IBS. There were no significant differences in terms of mean age (p = 0.290), body mass index (p = 0.212), visual analog scale (p = 0.965), duration of attacks (p = 0.692), and episodic/chronic type (p = 0.553). Osmophobia was seen in 43.5%; phonophobia in 68.7%, and photophobia in 47.0% of the patients, and only osmophobia was significantly associated in women in the IBS-C group (p = 0.001). Conclusion: In female patients with TTH, a higher level of constipation was detected. The relationship of these two diseases suggests that they may share common mechanisms. This is the first study showing the relationship of osmophobia with constipation.
Safety of transcranial direct current stimulation in a patient with deep brain stimulation electrodes
Authors: Iannone Aline , Allam Nasser , Brasil-Neto Joaquim P.
Published: April 2019

ABSTRACT Background: Transcranial direct current stimulation (tDCS) has been investigated in movement disorders, making it a therapeutic alternative in clinical settings. However, there is still no consensus on the most appropriate treatment protocols in most cases, and the presence of deep brain stimulation (DBS) electrodes has been regarded as a contraindication to the procedure. We recently studied the effects of cerebellar tDCS on a female patient already undergoing subthalamic nucleus deep brain stimulation (STN-DBS) for generalized dystonia. She also presented with chronic pain and depression. With STN-DBS, there was improvement of dystonia, and botulinum toxin significantly reduced pain. However, depressive symptoms were worse after STN-DBS surgery. Methods: Neuromodulation with 2 mA anodal cerebellar tDCS was initiated, targeting both hemispheres in each daily 30 minute session: 15 minutes of left cerebellar stimulation followed by 15 minutes of right cerebellar stimulation. The DBS electrodes were in place and functional, but the current was turned off during tDCS. Results: Although our goal was to improve dystonic movements, after 10 tDCS sessions there was also improvement in mood with normalization of Beck Depression Inventory scores. There were no complications in spite of the implanted STN-DBS leads. Conclusion: Our results indicate that tDCS is safe in patients with DBS electrodes and may be an effective add-on neuromodulatory tool in the treatment of potential DBS partial efficacy in patients with movement disorders.

Published: April 2019

ABSTRACT Cerebellar ataxia is a common finding in neurological practice and has a wide variety of causes, ranging from the chronic and slowly-progressive cerebellar degenerations to the acute cerebellar lesions due to infarction, edema and hemorrhage, configuring a true neurological emergency. Acute cerebellar ataxia is a syndrome that occurs in less than 72 hours, in previously healthy subjects. Acute ataxia usually results in hospitalization and extensive laboratory investigation. Clinicians are often faced with decisions on the extent and timing of the initial screening tests, particularly to detect treatable causes. The main group of diseases that may cause acute ataxias discussed in this article are: stroke, infectious, toxic, immune-mediated, paraneoplastic, vitamin deficiency, structural lesions and metabolic diseases. This review focuses on the etiologic and diagnostic considerations for acute ataxia.

ABSTRACT It is currently unknown how genetic factors may influence the clinical course of multiple sclerosis (MS). Objective: We examined the impact of CIITA polymorphisms −168A/G (rs3087456) and +1614G/C (rs4774) on the risk of disability progression, severity and on responses to first-line immunomodulator treatments. Methods: Genomic DNA was extracted from blood samples. We used ABI3730xl and GeneMapper v.4.0 software to identify genotype variations. All patients were followed up and clinically reassessed at three-month intervals. Disability progression was measured by the Expanded Disability Status Scale and disease severity by the Multiple Sclerosis Spasticity Scale (MSSS). Results: We included 37 men and 80 women. We found no evidence regarding the influence of the single nucleotide polymorphisms studied in the Expanded Disability Status Scale or therapeutic response of the evaluated drugs. We performed a logistic regression analysis with the MSSS and found that a less severe MS course was associated with wild type CIITA −168AA and CIITA +1614GG, as the chance of the patient progressing to MSSS2 and MSSS3 decreased in 61% and 75% with CIITA −168AA and 66% and 75% with CIITA +1614GG, respectively (p < 0.0001). Although less significant, the CIITA +1614 GC also pointed to a less severe MS course and the chance of the patient progressing to MSSS3 decreased 79% (p = 0.015). We also observed that the CIITA −168GG genotype was more frequent in MSSS2 and MSSS3 and had 40% lower odds ratio to becoming more severe MS. Conclusion: These data suggest that CIITA −168AA, CIITA +1614GG and CIITA +1614 GC polymorphisms may be associated with a better MS clinical course. This knowledge may be useful for a better understanding of MS and its therapeutic management.

ABSTRACT: The present study investigated the circulation of avian metapneumovirus (aMPV) in wild birds in Brazil. To do so, 131 samples from 366 oropharyngeal or cloacal swabs collected from 18 species of birds were tested individually or in pools by RT-PCR. Samples detected by RT-PCR were selected for DNA sequencing. Thirteen (9.9%) samples were detected by the RT-PCR targeting the N gene and four out of 13 samples were sequenced. Sequencing results showed a high identity with the aMPV subtype A. Our results confirm the circulation of the aMPV subtype A in wild birds in Brazil even five years after its last detection.

Published: April 2019

ABSTRACT Infected seeds are one of the main pathogen transmission vehicles, and they are responsible for significant losses in production fields; phytosanitary defense depends on the inoculum and climatic factors. Thus, in this study, it was aimed to identify climatic variables of the regions that propitiate the production of Brachiaria brizantha ‘BRS Piatã’ seeds infected with phytopathogenic fungi. Temperature and rainfall data were obtained from 10 production fields, and phytosanitary quality of the seeds was evaluated with the filter paper method; the means were compared using the Kruskal–Wallis non-parametric analysis. Principal component analysis was performed to determine the relationship between the climatic variables and seed phytosanitary quality. Sites with maximum temperatures higher than 30 °C, mean values close to 25 °C, and rainfall less than 82 mm during harvest were favorable to the incidence of Fusarium spp. The incidence of Bipolaris sp. in the seeds of Piatã grass was favored by temperatures around 19 and 20 °C during the maturation phase. The highest incidence of Exserohilum sp. occurred at the sites in which the temperature during harvest was close to 20 °C and accumulated rainfall, between 167 and 181 mm.

ABSTRACT This study aimed to evaluate the gas exchanges and photosynthetic pigments of soursop seedlings cv. ‘Morada Nova’ irrigated with saline waters and subjected to exogenous application of hydrogen peroxide by seed soaking and foliar spraying. The study was carried out using plastic bags under greenhouse conditions at the Center of Technology and Natural Resources of the Federal University of Campina Grande, PB, Brazil, using a eutrophic Regolithic Neosol of sandy loam texture. Treatments were arranged in a randomized block design, in 5 x 5 factorial scheme, which consisted of five levels of electrical conductivity – ECw (0.7; 1.4; 2.1; 2.8 and 3.5 dS m-1) of irrigation water and five concentrations of hydrogen peroxide - H2O2 (0, 25, 50, 75 and 100 µM), with four replicates and three plants per plot. As the salt stress increased, there were reductions in internal CO2 concentration, instantaneous carboxylation efficiency and water use efficiency, and instantaneous carboxylation efficiency was the most sensitive variable. Hydrogen peroxide at concentrations of 25 and 50 µM attenuated the deleterious effects of water salinity on stomatal conductance, CO2 assimilation rate and chlorophyll a content, and the concentration of 25 µM was the most efficient. The content of chlorophyll b and carotenoids of soursop cv. ‘Morada Nova’ had the deleterious effects caused by the salinity of irrigation water mitigated by the exogenous application of hydrogen peroxide in the concentration of 25 μM.

Published: April 2019

ABSTRACT ‘Cedro doce’ [Pochota fendleri (Seem) Alverson & Duarte] is a native forest species in Amazon with great ecological and economic importance. Understanding nutritional requirements of the species allows cultivating Pochota fendleri with more efficient fertilization practices since its initial growth, as a seedling. Thus, this research aimed to evaluate the symptoms of nutritional deficiency of young ‘cedro doce’ plants. The experiment was carried out from September to December 2016, under greenhouse conditions, at Embrapa Roraima, in Boa Vista, RR, Brazil. The experiment was a randomized complete block design with seven treatments [complete solution and individual omission of the macronutrients (N, -P, -K, -Ca, -Mg, -S)] and three replications. Each experimental plot corresponded to a pot with one plant, corresponding to 21 plots. At 77 days after transplanting the seedlings to the pots, the plants were evaluated for symptoms of nutritional deficiency: total height, collar diameter, leaf number, chlorophyll a and b, chlorophyll a/b index ratio, shoot and root dry mass, and root/shoot ratio. The macronutrients omission caused nutritional deficiency symptoms in all ‘cedro doce’ plants. In general, P and N omission caused the least development of plants. This result is an indicative that ‘cedro doce’ is a high demanding species for both nutrients, especially phosphorus.

ABSTRACT The objective of this study was to identify sorghum varieties that have growth and grain yield potential under saline conditions. The study was conducted in 2016 at a greenhouse of the Embrapa Semiárido, in Petrolina, state of Pernambuco, Brazil (9° 8’ 8.9’’ S, 40° 18’ 33.6’’ W, and altitude of 373 m). A randomized block experimental design, with a 6 × 5 factorial arrangement, and three replications was used. The treatments consisted of six grain sorghum varieties (1011-IPA, 2502-IPA, 2564-IPA, 2600-IPA, Ponta Negra, and Qualimax), and five salinity levels of the irrigation water (ECw = 0, 1.5, 3.0, 6.0, and 12.0 dS m-1). Plant height, stem diameter, dry matter yield, width and length of the +3 leaf, total leaf area, water use efficiency, and grain yield were evaluated. The sorghum varieties 2502-IPA and 1011-IPA presented the highest grain yields when using an ECw of 6.0 dS m-1, followed by Ponta Negra, Qualimax, and 2600-IPA. The 2564-IPA, 2600-IPA, and Qualimax varieties were more sensitive to the salinity effects, with reductions of 50% of the production with ECw of 3.52, 2.75, and 4.38 dS m-1, respectively.

Published: April 2019

ABSTRACT Eggplant is a functional food rich in antioxidants and its consumption brings several benefits to human health. Phenolic compounds and anthocyanins are some of the compounds that interfere in this antioxidant capacity and may be influenced by the mineral nutrition of the plant. The objective was to analyze the effects of potassium and phosphate fertilization on the agronomic and physico-chemical characteristics and bioactive compounds of eggplant fruits. The work was carried out at the Taboquinha Farm, in the municipality of Baldim, MG, at coordinates 19º 17’ 12.5” S and 43º 54’ 01” W, from March to October 2017. The experimental design was randomized blocks in a 4 x 4 factorial scheme with four replicates. The factors under study were phosphorus and potassium represented by four doses of P2O5 (0, 60, 120 and 180 kg ha-1) and four doses of K2O (0, 25, 50 and 75 kg ha-1), respectively. It was concluded that potassium and phosphate fertilization did not improve the agronomic and physico-chemical characteristics of eggplant fruits; however, potassium fertilization in greater amounts promoted improvements in the contents of phenolic compounds. The lack of phosphorus increased the anthocyanin content in the fruits, but interfered negatively in their shape. Potassium and phosphate fertilizations produced antagonistic effects on fruit moisture content.

Published: April 2019

ABSTRACT The quality of seeds of forage species can be influenced by the different harvesting methods used. The aim of this study was to evaluate the physical and physiological quality of seeds of Panicum maximum, cultivars ‘Massai’ and ‘Mombaça’, obtained by the methods of ground sweeping and direct heading (cutting of the panicles) of different farmers in the year 2014. The test consisted of three lots of each cultivar from seed farmers in the state of Goiás, Brazil. The experimental design was completely randomized, in 3 x 2 factorial scheme (farmer x harvesting methods) with four replicates. The following variables were analyzed: physical purity, 1000-seed weight; germination and first count of germination. At the end of the germination the percentage of dormancy and dead seeds were evaluated by the tetrazolium test of the remaining seeds, in addition to the abnormal seedlings. The data were submitted to analysis of variance and the means of the treatments were compared by Tukey test at 0.05 probability level. Seeds of P. maximum ‘Massai’ and ‘Mombaça’ collected by ground sweeping have superior physiological quality despite the low level of purity of the lots, compared to direct heading method.

Resumo Objetivo: Este estudo tem como objetivo comparar o consumo de água e energia em quatro configurações do ciclo (número de pulsos na fase de condicionamento, tempo de secagem e valor de ajuste da profundidade do vácuo) para esterilização a vapor. Métodos: Estudo descritivo de quatro diferentes configurações de ciclo: na configuração A, os pulsos de vácuo da fase de condicionamento foram ajustados no total de três, com a profundidade de vácuo em 90 mbar e o ponto positivo de pressão em 1500 mbar. A fase de secagem foi ajustada em 45 minutos com a profundidade de vácuo em 90 mbar. Os consumos de água e energia foram medidos durante toda a fase de condicionamento e a cada 15 minutos durante a fase de secagem. Na configuração B, a profundidade de vácuo na fase de condicionamento foi de 150 mbar e os outros parâmetros foram idênticos aos da configuração A. Nas configurações C e D, o número de pulsos de vácuo foi ajustado no total de cinco, com o ponto positivo de pressão em 1500 mbar nas duas configurações e a profundidade de vácuo de 90 mbar e 150 mbar, respectivamente. Resultados: A água consumida durante a fase de secagem teve grande impacto sobre o consumo total de água durante todo o ciclo. Conclusão: Este estudo evidenciou que o aumento do tempo de secagem para solucionar pacotes molhados aumenta o consumo de água, um recurso natural escasso, que deve ser utilizado como última opção para obter pacotes secos ao fim do ciclo.

RESUMO O jardim moderno brasileiro foi criado em Recife por Roberto Burle Marx na década de 1930. Ele concebia o jardim como uma reintegração estética dos elementos da natureza onde a vegetação era elemento principal. Com essa intenção, projetou treze jardins públicos entre 1935 e 1937, incluindo a Praça de Casa Forte, seu primeiro projeto. Sendo o jardim perecível e renovável, segundo a Carta de Florença, por toda dinâmica física e biológica, a falta de conservação provoca sua degradação. Assim sendo, apresenta-se neste artigo a historiografia da Praça de Casa Forte, de forma a subsidiar ações efetivas de conservação.

A Tradição Alemã do Cultivo de si (Bildung) e sua Significação Histórica
Authors: Alves Alexandre
Published: April 2019

Resumo Este artigo tem como objetivo analisar o significado histórico do ideal alemão de formação ou cultivo de si (Bildung), considerando diferentes usos e interpretações ao longo do tempo. Com base na semântica histórica de Reinhart Koselleck e na bibliografia sobre o tema, ele reconstrói as principais transformações na sua estrutura semântica desde as origens na baixa Idade Média até a institucionalização no sistema escolar alemão no século XIX. O desenvolvimento do ideal de Bildung na Alemanha é marcado pela tensão entre sua função de integração por meio da educação e sua função como instrumento de distinção social. A reflexão sobre esse ideal educacional é apresentada como contraponto às práticas educativas atuais, baseadas nos imperativos do mercado e na gestão neoliberal do capital humano.

ABSTRACT This work evaluated the effect of pollination on the quality of seeds and plantlets of Eugenia uniflora L., as well as on the regenerative capacity of the seeds. Twelve individuals were monitored for their phenology and their floral visitors. Recently-opened flowers were subjected to self-pollination (SP), cross-pollination (CP) and natural pollination/control (C) treatments. The seeds obtained were evaluated for their germination and the resulting seedlings were transferred to a greenhouse and evaluated for their height, stem diameter, number of leaves, leaf area and fresh and dry mass of root, stem, and leaves. SP, CP and C seeds were fractionated into two and four parts and evaluated for their ability to germinate and produce normal seedlings. Seeds and seedlings from manual cross-pollination were the most vigorous. The worst performance of the natural pollination (C) evidenced the pollen limitation caused by the scarcity of efficient pollinators in the study area.

ABSTRACT Sesbania virgata is a legume used in the restoration of degraded areas and forms a symbiosis with arbuscular mycorrhizal fungi (AMF). Its seeds exude secondary metabolites that may influence the colonization by AMF. In this work, we studied the effects of seed (SE) and root exudates (RE) of S. virgata on the asymbiotic phase of Gigaspora albida. Spores of G. albida were germinated in medium supplemented with different concentrations of SE or RE. After seven days, spore germination was stimulated (46.6%) in the medium supplemented with the highest concentration of SE, while the mycelial growth was stimulated with the lowest SE concentration. In turn, RE had no effect on the fungal asymbiotic phase. We concluded that SE exert a positive effect on the asymbiotic phase of G. albida and that the different effects between SE and RE of S. virgata can be explained by their distinct content of secondary metabolites.
The adoption of Article Processing Charges as a business model by Brazilian Open Access journals
Authors: APPEL Andre Luiz , ALBAGLI Sarita
Published: April 2019

Abstract Different funding and business model alternatives for Open Access to scientific publication have been discussed and tried, either by Gold open access journals or by the ‘hybrid’ ones. A growing number of both types of scholarly journals have adopted a publication fee – more specifically an Article Processing Charge – as their open access business model, a procedure that has been the subject of controversies. The objective of this study is to characterize Brazilian open access journals that adopt article processing charges. The main contribution of this study is to audit and support decision making of editorial policies and business models for open access that are being proposed by and for Brazilian journals. We defined a sample of Brazilian open access journals using article processing charges extracted from the Directory of Open Access Journals database in April 2018 along with their classification in the Scimago Journal Ranking, Journal Citation Reports and Qualis Capes system, considered as an indicator of prestige of academic journals. The study reveals that a small number of Brazilian open access journals are currently applying article processing charges, with practices varying mainly according to fields of study, types of organization and classification according to the Qualis system.

O objetivo do estudo é compreender o modo como Equipes de Saúde Bucal da Atenção Primária à Saúde articulam, no agir profissional, competências de acolhimento & acesso de necessidades de saúde bucal. Trata-se de estudo de caso do tipo único e integrado com abordagem qualitativa. Um roteiro baseado no agir em competência apoiou a realização de nove grupos focais (16 cirurgiões-dentistas, cinco auxiliares, sete técnicos de saúde bucal e dois cirurgiões-dentistas residentes). Na implantação de protocolos de acolhimento & acesso persiste a priorização de demandas espontâneas e de urgências dos usuários ao consultório odontológico. Práticas inovadoras de acolhimento & acesso relacionam-se com competências subjetivas dos trabalhadores no trabalho coletivo e na renormalização entre protocolos e realidades de saúde. Desenhos de educação permanente em Saúde devem propiciar o debate de valores entre instituições de ensino e serviços.

ABSTRACT BACKGROUND: The maintenance of nutrition for the person with ileostomy is a major challenge despite to the proper management of stoma eliminations. OBJECTIVE: This study aimed to evaluate the nutritional status of people with ileostomy. METHOD: This is a cross-sectional study carried out on a population of 17 people with ileostomy enrolled in the Service of Attention to the Health of the Person with Stoma of level II, referring to a health region in Minas Gerais. The anthropometric evaluation consisted of the collection of weight, height, and calculation of body mass index. A 24-hour food recall and the nutritional assessment method Global Subjective Assessment were also evaluated. The data were analyzed by the Dietbox software, where the ingested nutrients were estimated, and by the Statistical Package for the Social Sciences version 22.0. RESULTS: There was a predominance of a population composed of people over 50 years old, female, married and single, with family income between two and three minimum wages, incomplete elementary school and that did not exercise paid activity. The cancer was given as the main diagnosis that originated the stoma and had a surgery time of less than two years. Regarding nutritional status, most of the interviewees presented adequate body mass index, but more than half reported significant weight loss after the ileostomy. The predominant nutritional diagnosis provided by the General Subjective Assessment was “suspected malnutrition/moderate malnutrition”. On the other hand, the contribution of energy, carbohydrates, lipids, sodium, potassium, magnesium and vitamin B12 was considered insufficient in almost all the participants. CONCLUSION: Therefore, it is suggested the periodic evaluation of the nutritional status of this population. Thus, it is expected that preventive, therapeutic and maintenance dietary diagnosis and planning may contribute to the nutritional status of the person with the ileostomy.

ABSTRACT BACKGROUND: One of the most feared complications with the use of cyanoacrylate for treatment of gastric varices is the occurrence of potentially life-threatening systemic embolism. Thus, endoscopists are turning towards new techniques, including endoscopic coiling, as a potentially safer and more effective treatment option. However, no studies have been performed comparing the two techniques. OBJECTIVE: This study aims to compare the safety and efficacy of endoscopic ultrasound guided coil and cyanoacrylate injection versus the conventional technique of injection of cyanoacrylate alone. DESIGN: A pilot randomized controlled trial. METHODS: Patients randomized into group I were treated with coil and cyanoacrylate, and those in group II with cyanoacrylate alone. Flow within the varix was evaluated immediately after the treatment session and one month following initial treatment. If thrombosis was confirmed, additional follow-up was performed 4 and 10 months following initial treatment. All patients underwent a thoracic computerized tomography scan after the procedure. RESULTS: A total of 32 patients, 16 in each group, were followed for an average of 9.9 months (range 1-26 months). Immediately after the procedure, 6 (37.5%) group-I patients and 8 (50%) group-II patients presented total flow reduction in the treated vessel (P=0.476). After 30 days, 11 (73.3%) group-I patients and 12 (75%) group-II patients were found to have varix thrombosis. In both groups, the majority of patients required only one single session for varix obliteration (73.3% in group I versus 80% in group II). Asymptomatic pulmonary embolism occurred in 4 (25%) group-I patients and 8 (50%) group-II patients (P=0.144). No significant difference between the groups was observed. CONCLUSION: There is no statistical difference between endoscopic ultrasound guided coils plus cyanoacrylate versus conventional cyanoacrylate technique in relation to the incidence of embolism. However, a greater tendency towards embolism was observed in the group treated using the conventional technique. Both techniques have similar efficacy in the obliteration of varices. Given the small sample size of our pilot data, our results are insufficient to prove the clinical benefit of the combined technique, and do not yet justify its use, especially in light of higher cost. Further studies with larger sample size are warranted.
Drive-in torque for self-tapping screws into timber

Self-tapping screws have been widely used in timber constructions. The current practice considers self-tapping screws perform best in connecting two members when they are fully threaded; however, the drive-in resistance caused by the friction between the wood and the screw can potentially damage the screw and reduce the effectiveness of its applications. The relationship between their thread configuration and the drive-in torque force has not been investigated, and the question as to how would knots in the member affect the drive-in force, remains a unanswered. In this study a series of tests was conducted, aiming to demonstrate the influence of thread configuration on the drive-in torque of screws. Two types of self-tapping screws and three different thread configurations were studied. The drive-in torque for partially threaded screws was found to be significantly slower than that of fully threaded ones. The results showed that knots can significantly influence the positioning of the screw and increase the drive-in torque. The application of a pre-drilled hole was found to be an effective way to minimise the influence of knots. This paper points out that with appropriate consideration of thread configuration, partially threaded self-tapping screws can not only achieve the same efficiency as fully threaded ones, they will also benefit from reduced drive-in torque force.

In this study, (Ni70Si30)100−x Fe x (x = 0, 5, 10) alloys were synthesized through the arc-melting technique under a vacuum/argon atmosphere. The microstructural properties and microhardness of the nickel (Ni)–silicon (Si)–iron (Fe) alloys were characterized. These alloys were investigated by X-ray diffraction (XRD), optical microscopy (OM), scanning electron microscopy (SEM) and Vickers microhardness measurement. The XRD results showed that all alloys have some intermetallic phases such as Ni2Si, Fe2Si, Ni74Si26 and Fe3Ni. These phases were confirmed by SEM-energy-dispersive X-ray spectroscopy analyses. From OM images, planar and dendritic growths were observed. The obtained phases affected positively the microstructures of the alloys. Thus, the microhardness values of the alloys improved and were determined to be in the range 866–1024 HV. Moreover, these microhardness values revealed that the iron content in the the nickel–silicon alloy system was a very significant factor to be determined increasing and decreasing of the the microhardness values the alloys.
