Après avoir été soutenue en 2017, la croissance de l’économie belge est redevenue plus modeste en 2018. L’expansion de l’économie belge resterait modérée en 2019. Alors que la demande intérieure devrait être soutenue par l’amélioration de la situation du marché du travail et du pouvoir d’achat des ménages, de même que par un certain optimisme des entreprises, la contribution de la demande étrangère serait en revanche réduite en raison d’un ralentissement de la croissance de l’économie mondiale et du commerce international. De 1,5 % en 2018, la croissance du PIB belge diminuerait à 1,3 % en 2019.

En résumé , nos prévisions macroéconomiques pour 2019 sont les suivantes:

L’économie belge devrait croître de 1,3 % en 2019.

L’emploi augmenterait, en termes nets, de 37.900 unités en 2019.

Le nombre de demandeurs d’emploi diminuerait de 15.200 unités en 2019.

L’inflation générale des prix à la consommation s’élèverait à 1,8 % en 2019.

Le déficit budgétaire des administrations publiques serait de 1,6 % du PIB en 2019.
The ageing of populations in Belgium: Current situation and perspectives
Authors: Bourguignon Mélanie , Sanderson Jean-Paul , Gourbin Catherine
Published: May 2019

For many decades now, population ageing is observed in every Western countries, as the result of the demographic transition. This article focuses on these issues through the particular lens of the demographer. The first section is focused on the evolution of ageing since 1970, situating Belgium in its wider context as a European nation and analysing spatial differences within Belgium according to standard demo-graphic indicators. The increase in the population over 60 and especially over 80 comes along with a transformation in the population profile. In the second section we look at consequences of ageing in terms of health through an indicator that has now become standard, that of healthy life expectancy. With death taking place at ever older ages, the chance of experiencing health problems has also risen. If to-day’s health-care systems are vitally important in helping older people remain at home for longer, we have focused on the role of the family caregiver, a vital facet of health-care systems for the old. Finally, the third section is devoted to the socioec-onomic consequences of demographic ageing, especially in terms of the resilience of the social security system. Where possible, we draw comparisons with the situation in other European countries.

Authors: Borji Milad , Pouy Somaye , Yaghobi Yasaman , Nabi Bahram Naderi
Published: May 2019

Background and objectives

Tonsillectomy is one of the most commonly used pediatric surgeries with high stress levels for children and their parents. The present study was designed and implemented regarding the fact that limited studies have ever been carried out about the effects of complementary therapies such as acupressure on the preoperative anxiety levels in children throughout the world.

Materials and methods

Present study was a randomized clinical trial that was done in three groups with 144 children aged 5–12 years undergoing tonsillectomy. In present study, the children were allocated in three groups: intervention, control and sham. In the intervention group, the acupressure was applied on the Yintang point and in the sham group, was applied at a sham acupoint. No intervention was performed in the control group. Before and after intervention, the pediatric anxiety levels were measured using instruments. The results were analyzed using descriptive and inferential statistics such as the Kruskal-Wallis and Wilcoxon tests, chi-square (χ2) and analysis of variance (ANOVA) test. The significance level was considered p < 0.05.

Results

The total anxiety score in children was (70.39 ± 20.93) in the control group, (67.83 ± 16.78) in the intervention group and (71.40 ± 21.82) in the sham group, not significant difference (p > 0.05). The different in the overall anxiety score among children before intervention compare to after intervention was as following: Control group (–3 ± 17.46), intervention group (8.42 ± 32.98) and sham group (–4.32 ± 24.47).

Conclusion

Like other surgical procedures, the tonsillectomy has serious stress for children. Our study demonstrates that the acupressure has a significant effect on the level of preoperative anxiety in children undergoing surgery. Therefore, nurses can use this technique to reduce the pediatric anxiety.
Ameliorative effects of Annona muricata Linn. (Annonaceae) against potassium dichromate-induced hypertension in vivo: involvement of Kim-1/p38 MAPK/Nrf2 signaling
Authors: Ola-Davies Olufunke Eunice , Oyagbemi Ademola Adetokunbo , Omobowale Temidayo Olutayo , Akande Israel , Ashafa Anofi
Published: May 2019

Background

Recently, the incidences of hypertension and environmental pollution have increased significantly. This study investigates the antihypertensive effect of Annona muricata extract against K2Cr2O7-induced hypertension.

Methods

Fifty rats were used for this study, which were divided into five groups of 10 rats each. Rats in Group A received normal saline, and those in Groups B, C, D, and E were treated with A. muricata extract alone at 250 mg/kg, K2Cr2O7 at 30 mg/kg, pretreated with the extract at 250 mg/kg, and pretreated with gallic acid at 60 mg/kg for 14 days, respectively, and thereafter administered with a single intraperitoneal injection of K2Cr2O7 at 30 mg/kg.

Results

Administration of K2Cr2O7 significantly increased systolic, diastolic, and mean arterial pressure and caused prolonged QT and QTc intervals. Further, pretreatment with the extract at 250 mg/kg and gallic acid at 60 mg/kg significantly reduced high blood pressure to near-normal values. K2Cr2O7 intoxication led to significant increases in serum advanced oxidative protein products, myeloperoxidase, and xanthine oxidase, while serum nitric oxide (NO) also reduced significantly. Immunohistochemistry of the renal kidney injury molecule (Kim-1) and p38 MAPK showed increased expressions following the administration of K2Cr2O7 together with the downregulation of nuclear factor erythroid 2-related factor 2 (Nrf2). Pretreatment with the extract at 250 mg/kg and gallic acid at 60 mg/kg also increased the expressions of Nrf2 and downregulated Kim-1 and p38.

Conclusion

Together, we found that pretreatment with the extract at 250 mg/kg and gallic acid at 60 mg/kg normalized the blood pressure, reduced the markers of oxidative stress, and improved the antioxidant defense system and serum NO bioavailability.
Windowing Techniques for Reducing PAPR of OFDM in Li-Fi Systems
Authors: Abdulkafi Ayad Atiyah , Sileh Ibrahim Khalil , Hardan Saad Mshhain
Published: May 2019

In this paper, Li-Fi system based on orthogonal frequency division multiplexing (Li-Fi-OFDM) is presented. In these systems, light-emitting diodes (LEDs) are used to send information data using intensity modulation. LEDs have a limited dynamic range and the voltage-current characteristic shows a nonlinear behavior. Li-Fi-OFDM signal is used to drive these transmitter LEDs. However, LEDs chip overheating and nonlinear distortions occur, due to high peak-to-average power ratio (PAPR) of the OFDM signal. The proposed approach develops a new PAPR reduction method of OFDM in Li-Fi systems based on time-domain windowing techniques. Several windows such as rectangular, Hanning and raised cosine methods have been applied to the OFDM time-domain signal in order to reduce its PAPR while maintain acceptable bit error rate (BER) performance at receiver side. The simulation results of the work have shown the advantages of the offered method; the proposed scheme achieves a significant PAPR reduction compare to the unwindowed signals. Our proposed system also slightly improves the BER performance for all windowing methods employed.
Using height-corrected definition of metabolic syndrome in children and adolescents
Authors: Ma Chunming , Lu Qiang , Wang Rui , Yin Fuzai
Published: May 2019

Metabolic syndrome (MS) is common among children and adolescents. Age- and gender-specific references or age-, gender- and height-specific references were used in pediatric MS definitions. More recently, an increasing number of studies documented that the ratio of waist circumference (WC) to height (WHtR) and blood pressure to height (BPHR) were easy anthropometric indexes for detection of obesity and hypertension in children and adolescents. For these reasons, height-corrected MS definition was proposed. WHtR and BPHR were used as alternatives to WC and BP in the definition of MS. In the present review, we discuss the possibility of the height-corrected MS definition for identifying MS in children.

El tratamiento jurídico del stalking desde el prisma de las víctimas y los profesionales implicados: resultados de un análisis cualitativo
Authors: Villacampa Estiarte Carolina
Published: May 2019

La incriminación del stalking en 2015 ha determinado la aparición de estudios cuantitativos que permiten constatar la presencia de este fenómeno en España. Los resultados de estas investigaciones revelan que aunque las víctimas explican estos hechos a personas de su entorno, raramente los denuncian. Tal hallazgo determina la conveniencia de analizar el recurso de estas víctimas a los sistemas formales e informales de protección y, más concretamente, el tratamiento que reciben desde el ámbito asistencial y desde el sistema de justicia penal. El presente trabajo, tomando como base 17 entrevistas en profundidad realizadas a víctimas y 27 entrevistas a profesionales, intenta dilucidar cuáles son las necesidades de tutela de las víctimas, de un lado, y cuál es la valoración de la respuesta normativa al stalking, del tratamiento institucional ofrecido y la receptividad a la incorporación de alternativas al proceso penal por parte de los integrantes del estudio, de otro.
Lysenkoism Against Genetics: The Meeting of the Lenin All-Union Academy of Agricultural Sciences of August 1948, Its Background, Causes, and Aftermath

This article reviews the ideological, political, economic, social, cultural, personal, moral, and ethical factors that determined the conduct of the Lenin All-Union Academy of Agricultural Sciences session in August 1948, as well as the immediate...

Progress in genetics and evolutionary biology in the young Union of Soviet Socialist Republics (USSR) was hindered in the 1930s by the agronomist Trofim Lysenko, who believed that acquired traits are inherited, claimed that heredity can be changed by “educating” plants, and denied the existence of genes. Lysenko was supported by Communist Party elites. Lysenko termed his set of ideas and agricultural techniques “Michurinism,” after the name of the plant breeder Ivan Michurin, but they are currently known as Lysenkoism. Although Michurinism opposed biological science, Lysenko took up one academic position after another. In 1929, Nikolai Vavilov founded the Lenin All-Union Academy of Agricultural Sciences and became its head; it directed the development of sciences underpinning plant and animal breeding in the Soviet Union. Vavilov was dismissed in 1935 and later died in prison, while Lysenko occupied his position. The triumph of Lysenkoism became complete and genetics was fully defeated in August 1948 at a session of the academy headed by Lysenko. The session was personally directed by Joseph Stalin and marked the USSR’s commitment to developing a national science, separated from the global scientific community. As a result, substantial losses occurred in Soviet agriculture, genetics, evolutionary theory, and molecular biology, and the transmission of scientific values and traditions between generations was interrupted. This article reviews the ideological, political, economic, social, cultural, personal, moral, and ethical factors that influenced the August 1948 session, and its immediate and later consequences. We also outline current attempts to revise the role of the August session and whitewash Lysenko.
The RNA Polymerase II Core Promoter in Drosophila
Authors: Vo Ngoc Long , Kassavetis George A , Kadonaga James T
Published: May 2019

Transcription by RNA polymerase II initiates at the core promoter, which is sometimes referred to as the “gateway to transcription.” Here, we describe the properties of the RNA polymerase II core promoter in Drosophila. The core promoter is at a strategic position in the expression of genes, as it is the site of convergence of the signals that lead to transcriptional activation. Importantly, core promoters are diverse in terms of their structure and function. They are composed of various combinations of sequence motifs such as the TATA box, initiator (Inr), and downstream core promoter element (DPE). Different types of core promoters are transcribed via distinct mechanisms. Moreover, some transcriptional enhancers exhibit specificity for particular types of core promoters. These findings indicate that the core promoter is a central component of the transcriptional apparatus that regulates gene expression.

Published: May 2019

El síndrome compartimental crónico inducido por el ejercicio o el uso excesivo raramente afecta a los miembros superiores y se ha relacionado con actividades deportivas o laborales. Describimos un caso de un paciente con diagnóstico de síndrome compartimental crónico de antebrazo, de características poco habituales, tratado con fasciotomía mínimamente invasiva. Este síndrome debe sospecharse incluso en pacientes que no practiquen actividades de riesgo y que sufran dolor compartimental inespecífico. La fasciotomía con técnica mínimamente invasiva es una opción eficaz para curar este cuadro.  ABSTRACTChronic exertional compartment syndrome (CECS) of the forearm is uncommon and has been described in association with sport and work-related activities. We describe the uncommon presentation of a patient with CECS of the forearm who was treated through a min-invasive fasciotomy. CECS of the forearm must be suspected in patients with compartmental pain even if they do not practice risk activities. Mini-invasive fasciotomy is an effective option for the treatment of this pathology.

Preparing for Discharge From the Neonatal Intensive Care Unit
Authors: Gupta Munish , Pursley DeWayne M. , Smith Vincent C.
Published: May 2019

BACKGROUND:

Discharge readiness is a key determinant of outcomes for families in the NICU. Since 2003, using a broad set of outcome and process measures, we have conducted an ongoing quality improvement initiative to improve the discharge preparation process in our NICU and readiness of families being discharged from the NICU.

METHODS:

Iterative improvements to the discharge preparation process were made by a multidisciplinary committee. Discharge readiness was measured by using a parental and nurse survey for all families discharged from our NICU. Primary outcome measures included parental self-assessment of discharge readiness and nurse assessment of the family’s emotional and technical discharge readiness. Secondary outcome measures included assessment of specific technical skills and emotional factors. Process measures included nursing familiarity with family at discharge. Improvement over time was analyzed by using statistical process control charts.

RESULTS:

Significant improvement was seen in all primary outcome measures. Family self-assessment of discharge readiness increased from 85.1% to 89.1%; nurse assessment of the family’s emotional discharge readiness increased from 81.2% to 90.5%, and technical discharge readiness increased from 81.4% to 87.7%. Several secondary outcome measures revealed significant improvement, whereas most remained stable. Nurse familiarity with the family at discharge increased over time.

CONCLUSIONS:

Quality improvement methodology can be used to measure and improve discharge readiness of families with an infant in the NICU. This model can provide the necessary framework for a structured approach to systematically evaluating and improving the discharge preparation process in a NICU.

Este ha producido cambios en el uso del suelo agropecuario, la industria y las infraestructuras técnicas a través de la optimización de potencialidades, transformando la base productiva del municipio de agroindustrial a agrícola, aspecto considerado como su mayor aporte, así como influyendo en la mejora de los sistemas naturales, sociales y económicos locales.
Las energías renovables a escala urbana. Aspectos determinantes y selección tecnológica
Authors: Barragán-Escandón Edgar Antonio , Zalamea-León Esteban Felipe , Terrados-Cepeda Julio , Parra-González Alejandro
Published: May 2019

Tanto por deterioro ambiental como por efectos del calentamiento global, es necesario modificar el desarrollo urbano. Así, surge la necesidad de promover políticas públicas y una planificación organizada que incluya conceptos del aprovisionamiento energético con recursos urbanos internos para mitigar la presión que las ciudades infringen al ambiente. La tecnología actual posibilita que la ciudad cambie de modelo energético tradicionalmente basado en importar recursos externos, no obstante, es necesario revisar tecnologías que aprovechan los recursos urbanos para el autoaprovisionamiento. A través de encuestas a expertos internacionales y su discernimiento, se determinan las opciones tecnológicas que podrían modificar la matriz energética urbana, así como aspectos necesarios para su promoción. Se concluye que la energía solar, tanto fotovoltaica como solar térmica, despiertan, por ahora, el mayor interés entre las alternativas evaluadas, y que costos y regulaciones pueden ser aspectos determinantes para expandir su uso.
Evaluación de un modelo urbano nuevo. Santiago el Pinar, México, 1999-2013
Authors: Vázquez-Honorato Luis Arturo , Salazar-Martinez Bertha Lilia , García-Medina Karla María
Published: May 2019

El programa Ciudad Rural Sustentable (CRS) que implementó el Gobierno del estado de Chiapas en localidades como Santiago el Pinar hasta el año 2013 surgió como resultado de dos problemáticas: una de naturaleza social y otra territorial. La primera, debido a la necesidad de los grupos indígenas con una ubicación dispersa que, por consideraciones geográficas, climatológicas, funcionales y en deplorables condiciones de habitabilidad, no contaban con una vivienda adecuada. La segunda, a causa de los asentamientos que se encontraban ubicados en zonas de alto riesgo, con antecedentes de pérdidas de bienes materiales y vidas humanas. En este marco, el documento reflexiona sobre el resultado de dicha política pública, en busca de un nuevo modelo urbano, considerando el bienestar de la población a partir del hábitat y de sus hábitos para propiciar mejores condiciones de equilibrio social, económico y ambiental como pauta para su crecimiento.

Acceso al suelo urbano y riesgo ambiental. Comodoro rivadavia, Patagonia argentina.
Authors: Romeo Gustavo David , Vazquez Letizia
Published: May 2019

La conformación urbana de Comodoro Rivadavia en la Patagonia argentina ha sido influida históricamente por la extracción de hidrocarburos, condicionando el acceso al suelo urbano. Esta ciudad responde a una crisis ambiental global que tiene como emergente al riesgo, lo cual quedó reflejado durante las precipitaciones extraordinarias acaecidas en el otoño de 2017. El presente trabajo analiza cómo las dificultades de acceso al suelo son un componente fundamental en la conformación de escenarios de riesgo ambiental. Reconociendo que estos se corresponden con sistemas complejos y en la búsqueda de miradas que confluyan en la ecología política, se pretende vincular estas dificultades con la construcción de la vulnerabilidad. El enfoque metodológico contempló la realización de entrevistas, revisión de fuentes secundarias y el abordaje interdisciplinario. A manera de conclusión, sostenemos que las dificultades de acceso al suelo generadas por la industria petrolera fueron una causa estructural del desastre ambiental.

Hinkelammert, se argumenta que los mo-tivos del Zaratustra no significan un movimiento contra-moderno y anti-ilustrado, sino una forma de gestión cultural y filosófica de algunas élites ilustradas y urbanas.
Los fundamentos conceptuales de la propiedad intelectual: liberalismo y crítica
Authors: Fazio Ariel
Published: May 2019

En el contexto de nuevos cercamientos sobre la naturaleza y la cultura, la cuestión de los derechos de propiedad intelectual ha adquirido una relevancia inusitada, y ha redefinido la cuestión misma de la propiedad. El artículo examina las teorías de J. Locke y D. Hume, para confrontarlas con las posiciones que, desde el liberalismo contemporáneo, defienden o criti-can la propiedad intelectual. A partir de allí, se busca una línea superadora que trascienda los supuestos liberales sobre la propiedad intelectual en particular y la propiedad privada en ge-neral.
Desacuerdo sin falta y retractación Una defensa del relativismo sobre juicios de gusto
Authors: Bordonaba David
Published: May 2019

El trabajo se propone, en primer lugar, analizar el desacuerdo sin falta como elemento central en los juicios de gusto, y examinar tres posiciones: contextualismo deíctico, no deíctico y relativismo. En segundo lugar, mostrar cómo el contextualismo deíctico y el relativismo dan cuenta de dicho fenómeno, pero solo el segundo puede hacerlo y acomodarse a un fenómeno central en esos desacuerdos: la retractación
En la piel de las ideas Ensayismo y escritura filosófica en Alejandro Korn
Authors: Fielbaum Alejandro
Published: May 2019

A partir de la contraposición entre filosofía y ensayismo, realizada por Th. Adorno, se cuestiona el carácter de “fundador” de la filosofía latinoamericana atribuido a A. Korn, quien comprendió la filosofía como un ejercicio de escritura sin certezas de- finitivas. Al señalar la distancia entre realidad y lenguaje, la filosofía puede habitar dicha distancia en diversas formas, y cabe preguntar por su relación con la escritura. Contra el positivismo, Korn insiste en el carácter figurativo de toda metafísica como “poema dialéctico”, acercándola así al ensayo.
Consideraciones críticas de la noción de cuerpo propio
Authors: Diaz Romero Paula
Published: May 2019

El trabajo ofrece un análisis crítico a la noción de cuerpo propio (Leib) en M. Merleau-Ponty, como superación del dualismo cuerpo-mente. Se amplía dicha noción para integrar las experiencias del cuerpo físico (Körper) y posibilitar el diálogo entre fe-nomenología y medicina, al proponer una fenomenología del organismo doliente.

La dimensión religiosa de la vida cotidiana desde el proyecto filosófico de John Dewey
Authors: Patiño Martha
Published: May 2019

El artículo muestra cómo J. Dewey entiende “lo religioso”, no como experiencia sepa-rada, sino como intensidad de cada vivencia que realza y expande su cualidad estética. La vida cotidiana constituye el reino del hombre sobre la naturaleza que exige recobrar la relación originaria con esta y, desde allí, con Dios. Esto implica vivir de primera mano toda experiencia individual, toda vez que conlleva ser interpelado por las si-tuaciones problemáticas. Se explica la forma de dicho movimiento de la experiencia
Technical objects' ecological efficiency indicators control
Authors: Voinova S. A.
Published: May 2019

Traditional automatic control systems do not solve the task of limiting the harmful effects of technical objects on the environment. The problem is to increase the effectiveness of means of its protection against the harmful effects of industry. Relevant is the use of indicators of environmental performance of technical objects as controlled parameters. A new approach to the control of technical objects is proposed. As the main control parameter it proposed to adopt the level of their ecological efficiency. Complicating circumstances of solving the problem is the insufficient knowledge of the factors of harmful effects on objects of living nature, their intensity, interrelation, mechanism, strength, and dynamics of exposure. Improving the economic efficiency of technical objects leads to an increase in their ecological efficiency. The solution to the problem is facilitated by the fact that traditional ACS should be left in action, adding to them an ecological efficiency control component. Heat-powerengineering has a large impact on the environment through emissions and discharges of harmful substances and heat. To give to ASC the functions of controlling the ecological efficiency of the boiler (for SOy emission), it is necessary to apply an additional, new control loop - regulator of SOy concentration in furnace gases. An urgent task in the use of direct control of the ecological efficiency of boiler-furnace systems is the development and production of physical quantity sensors, reflecting the level of aggressiveness of the source of hazard, working in real time. Direct control of indicators of ecological efficiency is much easier in other branches of industry, in particular, in its food branch, where objects do not have a large-scale complex negative impact on the environment.
Quando grandes projetos urbanos acontecem? Uma análise a partir do Porto Maravilha no Rio de Janeiro
Authors: Sarue Betina
Published: May 2019

RESUMO Os grandes projetos urbanos são uma realidade no mundo, e recentemente também no Brasil. O Rio de Janeiro ensaia desde os anos 1980 a realização de um grande projeto urbano em sua região portuária que apenas agora está sendo implementado, configurando o primeiro projeto de tamanho porte a ser realizado no Brasil. A pergunta que se coloca é: quando, ou em quais condições os grandes projetos urbanos acontecem? A explicação recorrente na literatura associa a sua realização a fatores econômicos centrados na valorização da terra urbana e na competição entre cidades associada a dinâmicas do capitalismo global. Esse artigo busca apresentar um argumento complementar ao debate, que considera além do contexto macroeconômico, as condições institucionais e formais necessárias para viabilizar a implementação de tais projetos. Essa reflexão é feita a partir do debate sobre a governança urbana e de uma análise institucional histórica do caso do Porto Maravilha no Rio de Janeiro. Por fim, o artigo sugere que o tipo de análise apresentado a partir do caso carioca é importante para os estudos sobre grandes projetos urbanos uma vez que o entendimento dos processos institucionais ajuda a entender os impactos do projeto na governança da cidade, sendo que as articulações entre atores influenciam quem ganha o quê no resultado da política.
Análise orçamentária do Programa Brasil Quilombola no Brasil e no Maranhão: o ocaso de uma política pública
Authors: Teixeira Tadeu Gomes , Sampaio Camila Alves Machado
Published: May 2019

Resumo As políticas públicas direcionadas às comunidades quilombolas tiveram como marco o lançamento do Programa Brasil Quilombola (PBQ) e sua institucionalização com a Agenda Social Quilombola. O objetivo deste artigo é analisar a alocação orçamentária do PBQ e seu nexo com a execução de políticas públicas no Brasil e no Maranhão. A metodologia utilizada baseia-se em análise de dados das Leis Orçamentárias Anuais entre 2004 e 2014 e em análise documental. Os dados orçamentários foram obtidos no Portal Siga Brasil, do Senado Federal, que compila dados do Sistema Integrado de Administração Financeira (Siafi) do governo federal. Foram realizadas análises documentais no Plano Estadual de Ações Integradas do Plano Brasil Quilombola do Maranhão e no Relatório de Execução do Plano Brasil Quilombola, também do Maranhão. A análise temática de conteúdo orientou o trabalho com os dados. Os dados reunidos conduziram à conclusão de que o PBQ operou como um dispositivo de governo que incluiu simbolicamente as comunidades quilombolas, aparentemente atendendo demandas de movimentos sociais. Contudo, excluiu-as efetivamente, via regulação orçamentária. Além disso, constatou-se o ocaso, ao menos orçamentário, de políticas públicas com recorte racial no país no âmbito do governo federal.
Advances in vegetative propagation of Olive tree

Published: May 2019

Abstract In Brazil, there is a growing interest in the crop of the olive tree, especially in those regions considered suitable for cultivation, where low temperatures occur between 8ºC and 10ºC in the period before flowering. The areas with these characteristics are located mainly in the South and Southeast regions of the country, characterized by a temperate climate in function of altitude, with the occurrence of natural vernalization. The propagation is an integral part of the production chain and the first step towards the implantation of the olive tree crop or renovation of the existing orchards. Obtaining quality seedlings, besides guaranteeing uniformity and reliable varietal origin, is a factor that influences the whole life of the orchard, allowing to maximize the effects of climate and soil and mainly of crop treatments adopted for the culture. In the Laboratory of Propagation of Fruit Plants of the Department of Phytotechnology of the Eliseu Maciel School of Agronomy of the Federal University of Pelotas, we have sought to research micropropagation and minipropagation allied to the clonal gardens kept in a protected place, reducing the physical space and improving, mainly, the crop protection control. Olive tree seedlings propagated by different methods of asexual propagation, such as micropropagation, microcutting and minicutting, and they have their completion until the complete development in no-soil cultivation systems.

Abstract Objective: To evaluate the usefulness of elastography (using manual compression) as an additional diagnostic tool for children and adolescents with thyroid nodules. Materials and Methods: This was a prospective study conducted between September 2012 and August 2013 at a hospital in Brazil. We performed elastography, ultrasound, and fine-needle aspiration biopsy in 32 patients between 6 and 18 years of age who had, in total, 38 thyroid nodules. Results: The elastography findings correlated with the histopathological diagnosis in 78.5% of cases. In three patients, an unnecessary thyroidectomy could have been avoided if the elastography results had been prioritized. Only one malignant thyroid nodule was found to show high elasticity. Conclusion: Our results suggest that high elasticity of a nodule on elastography is associated with a low risk of thyroid cancer. If further confirmed in other studies, elastography may prove useful as a complementary test for screening thyroid nodules in children.
Não linearidade entre câmbio e preços no Brasil e implicações para uma estratégia de desenvolvimento econômico
Authors: FONSECA MATEUS RAMALHO RIBEIRO DA , ARAÚJO ELIANE CRISTINA DE , ARAÚJO ELISANGELA
Published: May 2019

RESUMO O objetivo deste artigo é realizar uma análise da política monetária no Brasil a partir de um modelo de Vetores Autorregressivos com Cadeias de Markov (MS-VAR), na busca de evidências da não linearidade da relação entre câmbio e preços no Brasil. A análise demonstrou que, em períodos de apreciação cambial, tanto pelo lado da demanda quanto da oferta, existe um conjunto de forças que determinam uma trajetória baixista para os níveis de preços, sugerindo que a taxa de câmbio tem um papel fundamental no controle da inflação. Contudo, se aponta a necessidade de reavaliação do papel do câmbio no Brasil.
O paradoxo constitucional brasileiro: direitos sociais sob tributação regressiva
Authors: FANDIÑO PEDRO , KERSTENETZKY CELIA LESSA
Published: May 2019

RESUMO Este ensaio analisa o paradoxo constitucional brasileiro, de combinar expansão de direitos sociais com tributação regressiva, remetendo-o ao momento constituinte de 1987. O que esse momento revela é que a atual configuração regressiva do sistema tributário brasileiro, cuja origem se encontra na “Constituição cidadã” de 1988, não decorreu da ausência de uma proposta tecnicamente consistente de tributação progressiva - o que não permite descartar a hipótese política: “gastos sociais, sim, mas tributação progressiva, não”.
How QUALIS CAPES influences Brazilian academic production? A stimulus or a barrier for advancement?
Authors: FERNANDES GUSTAVO ANDREY ALMEIDA LOPES , MANCHINI LEONARDO DE OLIVEIRA
Published: May 2019

ABSTRACT This study delves into the consequences of QUALIS CAPES. To do that, data on the editorial boards of the journals classified as A1 and A2 in the areas of Business, Accounting and Tourism; and Economics are collected. Findings show that the US and the UK dominate the academic production. Brazil and other emerging countries are not relevant. Issues of the five top journals of each area were analyzed, showing that QUALIS may bias research in the country to issues not connected to Brazilian questions.
