The paper presents the data on activity of the deposited catalyst based on vanadium. The developed catalyst allows conducting the process of oxidative conversion of propane into ethylene and hydrogen using CO2 as an oxidant. The study of the activity of the developed vanadium catalyst at the oxidative conversion of propane showed that the maximum ethylene yield was 24.5% at: C3H8:CO2=2:1, T=700°C and W=1000 h-1. The increase of temperature to 800°C resulted in the in formation of 27.5% hydrogen. By methods of BET and XRD the developed catalyst 5% V/Al2O3, is differed by increase of specific surface area and bonding of the carrier with active phase, contributing to increase of efficiency of the developed catalyst in the oxidative conversion of propane to ethylene and hydrogen.

Published: May 2019

The article deals with the process of establishment of engineering and technical clerisy and the corresponding organizational structures (infrastructures) on the example of the development of the oil and gas industry in Ivano-Frankivsk region – the Western region of the Ukrainian Soviet Socialist Republic. The main points of the research are the traditional principles of historicism, objectivity, systematicity, comprehensiveness, representationism and humanism. The purpose of the article is to describe the process of forming the scientific and technical potential and its infrastructure in Ivano-Frankivsk region in the twentieth century which is based on the analysis of scientific and historical literature and archive sources. The system of «scientific and technical progress» management of the country, the republic and the region has been revealed, which is based on the establishment of appropriate organizational structures for the coordination of research works.  It has been proved that the clerisy differs from seven western regions of the Republic in his powerful scientific and technical potential, which was concentrated in Ivano-Frankivsk Institute of oil and gas. Ivano-Frankivsk region is behind the neighboring Lviv region in the development of a number of scientific problems and production communications; it has been thought to be a sample in the process of the «socialist transformations». During the period from the late 40’s to the mid 60’s of the twentieth century an extensive network of scientific institutions and organizations in Ivano-Frankivsk region has been established that constituted the basis for the scientific and technical potential of the Western region of the USSR. The design and engineering agencies, design and technological organizations, research stations, research units and branches of higher educational institutions are various in the functional use and forms of activity, that have directed their work at solving the urgent economic problems of the region.

De Novo, Divergence, and Mixed Origin Contribute to the Emergence of Orphan Genes inPristionchusNematodes
Authors: Prabh Neel , Rödelsperger Christian
Published: May 2019

Homology is a fundamental concept in comparative biology. It is extensively used at the sequence level to make phylogenetic hypotheses and functional inferences. Nonetheless, the majority of eukaryotic genomes contain large numbers of orphan genes lacking homologs in other taxa. Generally, the fraction of orphan genes is higher in genomically undersampled clades, and in the absence of closely related genomes any hypothesis about their origin and evolution remains untestable. Previously, we sequenced ten genomes with an underlying ladder-like phylogeny to establish a phylogenomic framework for studying genome evolution in diplogastrid nematodes. Here, we use this deeply sampled data set to understand the processes that generate orphan genes in our focal species Pristionchus pacificus. Based on phylostratigraphic analysis and additional bioinformatic filters, we obtained 29 high-confidence candidate genes for which mechanisms of orphan origin were proposed based on manual inspection. This revealed diverse mechanisms including annotation artifacts, chimeric origin, alternative reading frame usage, and gene splitting with subsequent gain of de novo exons. In addition, we present two cases of complete de novo origination from non-coding regions, which represents one of the first reports of de novo genes in nematodes. Thus, we conclude that de novo emergence, divergence, and mixed mechanisms contribute to novel gene formation in Pristionchus nematodes.
Joint Estimates of Heterozygosity and Runs of Homozygosity for Modern and Ancient Samples
Authors: Renaud Gabriel , Hanghøj Kristian , Korneliussen Thorfinn Sand , Willerslev Eske , Orlando Ludovic
Published: May 2019

Both the total amount and the distribution of heterozygous sites within individual genomes are informative about the genetic diversity of the population they belong to. Detecting true heterozygous sites in ancient genomes is complicated by the generally limited coverage achieved and the presence of post-mortem damage inflating sequencing errors. Additionally, large runs of homozygosity found in the genomes of particularly inbred individuals and of domestic animals can skew estimates of genome-wide heterozygosity rates. Current computational tools aimed at estimating runs of homozygosity and genome-wide heterozygosity levels are generally sensitive to such limitations. Here, we introduce ROHan, a probabilistic method which substantially improves the estimate of heterozygosity rates both genome-wide and for genomic local windows. It combines a local Bayesian model and a Hidden Markov Model at the genome-wide level and can work both on modern and ancient samples. We show that our algorithm outperforms currently available methods for predicting heterozygosity rates for ancient samples. Specifically, ROHan can delineate large runs of homozygosity (at megabase scales) and produce a reliable confidence interval for the genome-wide rate of heterozygosity outside of such regions from modern genomes with a depth of coverage as low as 5–6× and down to 7–8× for ancient samples showing moderate DNA damage. We apply ROHan to a series of modern and ancient genomes previously published and revise available estimates of heterozygosity for humans, chimpanzees and horses.

Halitosis: Basic Principles About its Origin and Treatment Narrative Review
Authors: Barba DDS Lucía , Valerio DDS Irene
Published: May 2019

Halitosis is the presence of an unpleasant smell that emanates from the oral cavity. The etiology of halitosis is multifactorial, existing non oral, oral and extraoral causes. The volatile sulphur compounds (VSC): hydrogen sulfide and methyl mercaptan are the prominent elements of malodour. Intraorally there is a significant correlation between VSC concentrations and periodontopathogenic bacteria. In patients with no gum disease the halitosis is originated mainly in the dorsal surface of the tongue, so cleaning or brushing it is an effective method to prevent or decrease halitosis. There are multiple chemical options for the treatment of the malodour that will depend on the origin and severity of it. This article reviews the origin and mechanical and chemical treatments that are available.
Psychological Intervention Strategies According to the Clinical Conditions and the Biopsychosocial Variables of the Adolescent in the Dental Practice: Review of the Literature
Authors: Amaíz DDS Alejandro J. , Flores MSc Miguel A.
Published: May 2019

Epidemiologically, the teenagers make up a population subgroup with oral indicators that need attention in the field of public health. In addition, the majority of the dental faculties orient the dental education directed to the child and the adult, where the attention focused to the teen is usually deferred. Moreover, the ignorance in the biopsychosocial alterations and the clinical peculiarities inherent to adolescence, make the attention of these potentially complex patients. Therefore, the objective of this article is to carry out a review of the literature in order to offer the professional the tools or psychological resources (soft skills) for the approach of the adolescent population that attends the dental consultation. Currently, the "Odontohebiatría" describes the comprehensive and interdisciplinary care of adolescent oral health, with an emphasis on oral prevention and esthetics. In this way, modern dentistry demands an active participation of the professional, who must be familiar with the clinical conditions and the psychological variables that may affect the teenager; also, it is considered important the instruction and training in strategies of psychological intervention to offer an attention adapted to this age group.
Retreatment Efficacy of Endodontic Bioceramic Sealers: A Review of the Literature
Authors: Kakoura DDS Flora , Pantelidou DDS, PhD Ourania
Published: May 2019

The endodontic retreatment is a feasible solution when post-operative apical periodontitis persists or develops. The complete removal of the filling materials is important in order to ensure the unobstructed contact of the intracanal disinfectants with the microbes. As a new generation of bioceramic endodontic sealers has emerged, their removal efficacy from the root canal system during retreatment is a matter of concern among clinicians. The aim of this article is to provide a comprehensive review of the current literature on the retreatability of these novel obturating materials. A significant amount of bioceramic sealer remnants in the root canal walls was observed in all studies.  Even though canal cleanliness could not be obtained at an ideal level, the re-establishment of the working length and patency can be considered manageable and comparable to other endodontic sealers.

Authors: Estrada Murillo DDS Nilvert A. , Evaristo Chiyong DDS, MSc Teresa A.
Published: May 2019

The aim of the study was to evaluate the relationship between psycho-emotional states and the presence of bruxism in a sample of students at a public School of Dentistry in Lima-Peru. The sample was 181 randomly selected students. Bruxism and the psycho-emotional states such as: stress, anxiety (state and trait) and depression were studied and measured through validated instruments. The results showed a low but highly significant correlation (p <0.001) between bruxism, stress, depression and the anxiety state. It is concluded that emotional states contribute to the presence of bruxism in dental students.

The aim of this study was to explore the remineralizing effect of toothpastes based on Xilitol, Camellia Sinensis and Juniperus Communis. An in vitro experimental study was carried out in an 18 human premolars sample, which were treated with one of the 3 evaluated toothpastes and a control fluoride one. The atomic percentages of Ca and P were evaluated by Energy Dispersive X-ray Spectroscopy (EDS). In addition, the enamel surface of treated teeth was visualized by Scanning Electron Microscopy (SEM). The evaluations were carried out in three stages: pre-treatment, after an artificial demineralization process and after the treatment with the toothpastes. In the statistical analysis, the one-way ANOVA and Pearson correlation tests were used. Xilitol and Juniperus Communis showed the greatest gain of P ions compared to the control group (p<0.01). As for Ca, the group treated with xylitol-based toothpaste showed more ion gain compared with the control group (p<0.01). In the Pearson correlation test between Ca and P, statistically significant correlations were observed in all groups (p<0.01), ranging between r=0.7413 (Xylitol Group) and r=0.9510 (Control Group). We concluded that Xylitol paste showed the highest remineralizing property, both in the EDS analysis and in the SEM images.
Interdisciplinary Approach to Smoking in Dental Practice: Psychological Intervention Techniques Application
Authors: Amaíz Flores DDS Alejandro José , Flores Barrios MSc Miguel Ángel
Published: May 2019

Currently, in the dental community there is confusion and doubt about the extent of professional responsibility in the intervention and prevention of smoking, which could be attributed, to a large extent, to lack of knowledge about it. However, the dentist is committed to actively participate in this addiction as part of oral treatment. Therefore, this article presents an updated review of the international literature related to smoking from the perspective of dental consultation, focused on the use of psychological strategies to offer an interdisciplinary approach, which frames the role of the dentist and his team. In this way, health psychology offers several intervention techniques that are highly effective in reducing or eliminating smoking, namely: motivational interviewing, response prevention, stimulus control, problem solving training, cognitive-behavioral, progressive training in anxiety and stress reduction, social skills training, anger management and aggressiveness, contingency management, self-control, aversive stimulation techniques, gradual reduction technique of nicotine and tar consumption (RGINA), couple and family therapy to deal with conflict situations in interpersonal relationships and group therapy.
Elastosis in Actinic Cheilitis. Literature Review
Authors: Boza Oreamuno DDS, MSc Yadira V. , Rojas DDS, PhD Isolde G.
Published: May 2019

The extracellular matrix (ECM) plays an important role in the regulation of biological events, such as cell migration, proliferation and differentiation. Chronic exposure to ultraviolet (UV) light causes elastosis (to varying degrees), which corresponds to a basophilic degeneration of the ECM. Actinic cheilitis (AC) is a potentially malignant lip lesion induced by regular and prolonged exposure to UV light, which mainly affects the vermilion. AC lesions have a complex stroma characterized by the presence of elastosis, chronic inflammatory infiltrate of different intensity and the appearance of telangiectatic blood vessels. Within this inflammatory infiltrate a significant increase of mast cells (MCs) has been described, located especially around areas of elastosis and at the subepithelial zone. It has been proposed that actinic elastosis is produced both, by degenerative processes and by abnormal synthesis of elastic fibers by photodamaged fibroblasts, which is accompanied by morphological changes in collagen. Although the fibroblast would play a major role in actinic elastosis formation, several studies suggest that other cell types such as MCs also contribute significantly to actinic ECM damage. The purpose of this review is to discuss the characteristics of elastosis in AC.
Can Biological Markers Partially Explain the Link Between the Social Environment and Oral Health?
Authors: Barboza Solís MSc, PhD Cristina
Published: May 2019

Understanding how the social world affects humans´ health by “getting under the skin” and penetrating the cells, organs and physiological systems of the body is a key tenet in public health research. Here, we propose the idea that socioeconomic position (SEP) can be biologically embodied, potentially leading to the production of health inequalities in oral health across population groups. Recent studies show that being exposed to chronic stress across the life course could impact our health. Allostatic load (AL) is a composite biological measure of overall physiological wear-and-tear that could allow a better understanding of the potential biological pathways playing a role in the construction of the social gradient in adult health. However, to use biological measures to better understand the mechanisms that construct health inequalities in oral health has not been tested systematically. The purposes of this New Perspective is to discuss the value of using composite biological markers, such as AL, to analyze oral health. This can allow a better understanding of the mechanisms leading to health inequalities in oral health, and add some valuable information for implementing health interventions.

Introduction: Tooth development results from a highly coordinated epithelial-mesenchyme interaction in which mesenchyme cells originate the dental papilla and dental follicle, while ectodermal cells originate the enamel organ. Simultaneously, bone tissue is formed around the developing tooth, trapping it in a bony crypt. Tooth eruption requires the resorption of the coronal part of the bony crypt, followed by degradation of the lamina propria, most likely by metalloproteinases (MMPs) activity. Objectives:  The aim of this research was to determine MMP-2 expression in the dental germ cells (ameloblasts, odontoblasts, dental papilla and dental follicle) and surrounding tissues (alveolar bone and lamina propria) of rat molars throughout the eruptive process. Material and Methods: A total of 24 rats (4,6,9,11,14 and 16 days old) were used in this study. MMP-2 was detected through immunohistochemistry. A qualitative analysis was performed to investigate the expression of MMP-2 in the dental germ cells, lamina propria, and coronal and basal regions of the bony crypt. Results: MMP-2 expression was observed in the dental papilla cells, dental follicle, ameloblasts, odontoblasts and bone cells from the coronal and basal regions of the bony crypt. MMP-2 was also detected in the lamina propria during the mucosal penetration stage of tooth eruption. Conclusion: We conclude that MMP-2 may be important for the extracellular matrix rearrangement necessary for tooth development and secretion of its mineralized tissues.  We also conclude that MMP-2 may play a role in the extensive tissue remodeling during the intra-and-extra-osseous phases of the tooth eruption process.

Authors: Boza Oreamuno DDS, MSc Yadira V. , Evans Tinoco DMD, OPH Mónica , Guillén Colombari DMD, Path Diego , Torres Labardini DDS, OMS Ronald
Published: May 2019

Thymomas are the most common mediastinal neoplasms in adults. Patients with thymoma are frequently diagnosed with paraneoplastic syndromes and are generally associated with several autoimmune conditions. Sjögren's syndrome (SS) is an autoimmune inflammatory disorder, characterized by the lymphocyte-mediated destruction of the exocrine glands, which leads to the absence of glandular secretion, particularly salivary and lacrimal; hyposalivation can vary from a slight reduction in the flow of saliva with transient discomfort, to a serious deterioration of oral health and psychological distress. Mucous membrane pemphigoid (MMP) is a chronic, autoimmune disease that shows predominant mucosal involvement, most commonly affecting the oral cavity, followed by the conjunctiva, the nasal cavity and the esophagus; intraorally includes scaly gingivitis, vesicles, erosions covered by pseudomembranes and ulcers. The objective of this work is to present the first case of a patient with a history of thymoma, which, jointly presented SS and MMP; also highlight the importance of multidisciplinary management for an accurate and early diagnosis, as this increases the efficiency and efficacy of the treatment strategy.

Authors: Tulga DDS, PhD Ayça , Ayşe Şanal DDS, PhD Fatma , Ömür Dede DDS, PhD Doğu
Published: May 2019

The purpose of this preliminary study is to evaluate the push-out bond strength (PBS) of experimental dentin posts (EDPs) obtained from human and bovine teeth sterilized by autoclaving and gamma radiation. Eighty-four mandibulary premolars were obturated and divided into three post groups: the glass fiber group (Fb) human EDP group (Hm) and the bovine EDP group (Bv). Three subgroups (n=12) were obtained for each EDP groups according to the sterilization methods; no sterilization (Cnt), steam autoclaving (Aut), and gamma radiation (Rad) a total dose of 25 kGy. All posts were cemented to root canals using a dual cured resin cement (Panavia SA). After the micro slices (1mm in thickness) were obtained of each subgroup, PBS test was performed. Data were analyzed using two-way ANOVA and Tukey’s multiple comparison tests (α=.05). The post type and sterilization method was significantly effective on the PBS values according to the ANOVA (P<.001). No sterilization apllied EDP groups showed significantly higher PBS values than the sterilized groups (P<.001). Bv_Cnt (9.42 ±1.31) showed significantly lower PBS values than both Fb (12.36 ±1.54) and Hm_Cnt (11.06 ±1.38) groups (P<.001). Both steam autoclaving and gamma radiation affect the PBS values and fracture modes of EDPs negatively. The bovine EDPs are not as effective as human EDPs with regard to the PBS to the root dentin.
Fluoride Release of Giomer and Resin Based Fissure Sealants
Authors: Şişmanoğlu DDS, PhD Soner
Published: May 2019

Fissure sealants are applied to teeth to prevent caries development. The presence of the fissure sealant creates a protective barrier, which prevents plaque accumulation to the pits and fissure. They have a significant role in preventing pit and fissure caries. The aim of this study was to evaluate the time-dependent fluoride ion release of giomer- and resin-based fissure sealants. Fissure sealants were divided into 4 groups: BeautiSealant (Shofu, Japan), Clinpro Sealant (3M ESPE, USA), Helioseal F (Ivoclar Vivadent, Liechtenstein), Fissurit F (Voco, Germany). Disk shaped samples were prepared for each sealant material tested, and they were transferred into polyethylene vials containing 5 ml of deionized water. Fluoride ion diffusion was determined on days 1,2,3,7,14,21, and 28 (n=7). The fluoride concentration in these samples was analyzed using a pre-calibrated spectrophotometer in parts per million (ppm). These experiments were performed in triplicates at room temperature. ANOVA and Tukey’s HSD test were used for statistical analysis. BeautiSealant was released the highest amount of fluoride on day 1 (5.33 ppm), followed by a sudden decrease on the day 2 (2.17ppm). The burst effect was observed only in this group. Clinpro Sealant, Fissurit F and HelioSeal F groups presented fluoride release of 2.69, 2.94 and 2.91 ppm on the first day, respectively, without a significant difference (p > 0.05). After the first week, a constant fluoride release level has been reached. The fluoride release for the three resin-based fissure sealants was slightly lower than that for the giomer-based. After the first week, materials exhibited no significant difference and reached a plateau. The usage of a high and prolonged fluoride-releasing fissure sealant material should be considered by clinicians, particularly in patients with caries risk.

Gnostic Imagery in Disney’s Pinocchio
Authors: Burke Tony
Published: May 2019

The right film can work wonders for helping students understand difficult concepts in religion. Disney’s Pinocchio at once provides a visual metaphor for the gnostic version of the creation of humanity and conveys the anxiety that must have been felt by prospective Gnostics as they came to the realization that their well-known and beloved traditions could yield such disconcerting interpretations. But to what extent are the apparent gnostic elements in the film intended? And do they naturally emerge from the sources (Carlo Collodi’s 1881–1883 series of short stories) used to make the film? The same questions can be applied to the sources of gnostic texts and thus open up avenues of discussion about the creation, transmission, and interpretation of ancient Christian literature.
Loaf for Learning
Authors: King Sarah J
Published: May 2019

Cooking and eating in the Religious Studies classroom is a challenging and valuable pedagogical practice which turns upside down students’ individualist ideas of religion as belief inside people’s heads, drawing them out into the complexity of lived religion, and in so doing breaks open the modernist study of religion itself. Teaching with food upsets gendered stereotypes about whose religion counts, and it brings students into direct confrontation with the boundaries, borders, taboos and pleasures that are at the heart of religions and the religious. Cooking and eating with students reminds them that religion is not actually a category separate from the other aspects of human life and culture; it’s connected! With food, the classroom becomes a different place, where students move beyond religion as intellectual interiority into the complexity of everyday religion as lived.

This research was aimed to elaborate on the form of scaffolding given by learners on algebra problem-solving. The approach used is descriptive qualitative. The study conducted in a junior high school in Malang Regency with 25 students and only two students were selected as research subjects to be given scaffolding level 2. Data collection method begins by requiring learners to solve algebra and next identify the pattern of mistakes or mistakes. Learners who have wrong answers, used as research samples. The results prove the form of scaffolding given the subject. If the subject experiences an error in understanding the problem, the scaffolding is given asking the subject to re-read the problem properly and carefully and give direction questions. However, if the subject has difficulty in making the planning of the settlement, the scaffolding given is giving the subject the opportunity to rearrange the design of the right answer. If the subject experiences an error in carrying out the planning, the scaffolding given is asking the subject to pay attention to the mathematical concept and to be careful in operating algebra.
Uma poética da relação: a conversa infinita entre Édouard Glissant e Michel Leiris
Authors: Theophilo Gabriela Mitidieri
Published: May 2019

Este artigo apresenta uma leitura, em conjunto, de alguns textos dos escritores e etnógrafos Michel Leiris (França 1901-1990) e Édouard Glissant (Martinica, 1928-2011) a partir dos anos 1950. Nesse período Leiris fez estudos nas Antilhas, a pedido da UNESCO, e Glissant tornou-se seu aluno de etnografia na França. A partir de uma leitura inicial dos questionamentos de Leiris nessa década e, em seguida, dos escritos de Glissant, buscou-se demonstrar a intertextualidade entre as obras de ambos, resultante, sobretudo, das apropriações que Glissant estabeleceu dos textos de seu professor. Mais especificamente, foi demonstrado de que modo os conceitos de créolisation e de Relation, em Glissant, fundam-se em diálogo com as ideias de contato e de comunicação em Leiris.  Além disso, objetivou-se compreender, nas reflexões de ambos, os usos da noção de carrefour para representar as sociedades antilhanas, considerando-se os impactos teóricos e ético-políticos dessa formulação em suas obras.

Narrativas hagiográficas e devoção aos santos: notas sobre a (re)produção simbólica da santidade nos cemitérios
Authors: Soares Hugo Ricardo
Published: May 2019

Resumo: O presente trabalho tem como objetivo analisar a devoção aos santos no cemitério a partir de suas potencialidades ritualísticas e performático-narrativas. Para isso, sigo a composição do repertório hagiográfico que alimenta as práticas dos cultos rendidos a quatro santos da cidade paulista de São José dos Campos. Além da etnografia dos ritos devocionais, são tomadas como fontes da investigação algumas narrativas hagiográficas sobre personagens do imaginário religioso local. O ensaio procura estabelecer uma comparação dos modelos hagiográficos canônicos e das mitologias locais que, juntas, constituem e dão vida ao imaginário e à prática cotidiana da religião. A análise desta modalidade religiosa pode ser de grande valia para a compreensão da lógica ortoprática de produção e reprodução de sentidos no catolicismo.
The Suitability of a Transcultural Clinical Approach to Psychosomatic Disturbances in Reunion Island

Published: May 2019

Abstract Cultural foundations, beliefs and associated ritual practices delimit the relation to and the representation and lived experience of the body in specific ways. Language is the means through which the cultural specificity of both individual and shared mental content can be explored and worked with in therapy. This article presents beliefs about the body in a patient’s religion of origin and takes up the question of the role of the cultural dimension in psychosomatic phenomena. A case report gives indications of a novel therapeutic approach to this theme and highlights the intrinsic connection between cultural belonging and embodiment. Both the two-year long clinical intervention and analysis are grounded in transcultural and psychodynamic theories. The analysis shows how important it is to be aware of the patients’ cultural background and the resonance of history in the patients’ civilization.
Tornar-se Pai: A Paternidade como Inscrição Subjetiva da Finitude
Authors: Cherer Evandro de Quadros , Ferrari Andrea Gabriela , Piccinini Cesar Augusto
Published: May 2019

Resumo Este estudo investigou a experiência subjetiva da paternidade em dois momentos do desenvolvimento, no sexto mês e ao final do segundo ano de vida da criança. Participaram do estudo três pais primíparos, com idade de 30 a 45 anos e escolaridade de ensino superior. Utilizou-se um delineamento de estudo de caso coletivo, de caráter longitudinal, em que os pais responderam a entrevistas nos dois momentos propostos. As entrevistas foram analisadas com base na teoria psicanalítica. Os resultados corroboraram a expectativa de que tornar-se pai estaria associado à inscrição subjetiva da finitude. Esse processo indica um movimento intrínseco à paternidade, exigindo renúncias e lutos dos pais, movimento que permitiu o bebê ser tomado como objeto de desejo paterno.
Green propolis ethanolic extract in bean plant protection against bacterial diseases
Authors: Jaski Jonas Marcelo , Telaxka Fabio Junior , Moura Gabriela Silva , Franzener Gilmar
Published: May 2019

ABSTRACT: The aim of this study was to evaluate the ethanolic extract of green propolis (EEP) in the protection of common bean plants against two main bacterial cultures, bacterial blight (Xanthomonas axonopodis pv. phaseoli) and wildfire (Pseudomonas syringae pv. tabaci). Experiments on antimicrobial activity were performed, inducing phytoalexins, defense-related enzymes, and disease severity, under concentrations of 0, 0.5, 1.0, 2.5, and 5.0%. The EEP presented antimicrobial activity on both phytobacteria, causing a decrease in their development. It has also promoted a linear accumulation of phaseolin in bean hypocotyls according to the EEP concentration used. There was a reduction in the lesion area, which was caused by bacterial blight on bean leaves treated with EEP, and local and systemic effect were observed. Polyphenoloxidase was activated with 5% EEP, reaching the maximum activation time 62.5 h after application. An increase was observed in the activity of phenylalanine ammonia-lyase in plants treated with EEP, with local and systemic effect. Results indicated the potential of EEP in the control of these diseases.

ABSTRACT: The biomass pyrolysis process may be an alternative for the agricultural use of sewage sludge. This study aimed to evaluate the use of of biochars from mixture of sewage sludge and sugarcane bagasse (BB, 1:1 relationship sewage sludge and sugarcane bagasse) on sugar beet (Beta vulgaris L.) production and nutrition. A greenhouse experiment was conducted with five application rates of BB: 0, 2.5, 5, 7.5, and 10% (v/v), and two additional treatments, biochar from sewage sludge (BS, application rate 5% (v/v)) and conventional treatment (CV) that received lime and mineral fertilizer. The treated soils were incubated for 45 days, after which, seedlings were cultivated for 55 days. Biochar produce from sewage sludge and sugarcane bagasse is an alternative technology to reduce the potential for contamination of sewage sludge and to incorporate more stable carbon forms in the soil. Although, biochar has increased soil fertility, fine roots and nutrient uptake efficiency by sugar beet plants, total dry matter yield was significantly lower than that obtained in conventional treatment.
A construção do nacional: Ricardo Severo e a Campanha de Arte Tradicional no Brasil (1910-1930)
Authors: SILVA Joana Mello de Carvalho e
Published: May 2019

Resumo A Campanha de Arte Tradicional no Brasil, promovida por Ricardo Severo da Fonseca e Costa (1869-1940) entre as décadas de 1910 e 1930, foi composta por projetos de arquitetura; artigos e entrevistas publicadas em periódicos como O Estado de S. Paulo, a Revista do Brasil e A Cigarra, além de conferências proferidas em instituições como o Instituto Histórico e Geográfico de São Paulo, a Sociedade de Cultura Artística e o Grêmio Politécnico de São Paulo. Por meio dela, o engenheiro português construiu uma narrativa da história da arquitetura brasileira que foi pautada por e fomentou representações recorrentes da nação, reverberando nos escritos e nas políticas de preservação de intelectuais comprometidos com a criação de uma arte moderna genuína, entre eles José Marianno Filho, Mário de Andrade, Paulo Santos, Lucio Costa e Rodrigo Melo Franco de Andrade. Atento às especificidades do discurso de Severo, este artigo busca recuperar as motivações políticas e disciplinares de sua campanha; os nexos com sua experiência pregressa em Portugal, especialmente no campo da arqueologia; suas matrizes teóricas; suas fontes de pesquisa e seus veículos de divulgação, construindo pontes de diálogo entre o engenheiro português e seus contemporâneos.
PARTICIPATORY DESIGN OF A MONITORING PROTOCOL FOR THE SMALL-SCALE FISHERIES AT THE COMMUNITY OF TARITUBA, PARATY, RJ, BRAZIL
Authors: DIAS ANA CAROLINA ESTEVES , SEIXAS CRISTIANA SIMÃO
Published: May 2019

Abstract This paper aims to describe and analyze the design of the participatory monitoring protocol of Tarituba, a fishing community in Southern Brazil, and to discuss the setbacks for its implementation. The protocol aimed to integrate fishers’ scientific and technical knowledge under the ecosystem approach to fisheries, employing a pioneering method prevalent in the Brazilian coastal region: The Global Socioeconomic Monitoring Initiative for Coastal Management (SocMon). Monitoring goals lie in the socioecological sustainability of local fisheries and seek to solve conflicts resulting from fishing restriction due to the establishment of a Protected Area. SocMon was a useful tool to improve communication between and among fishers and managers. The legitimacy of the process was reinforced by participation of the fishers; however, the long waiting period preceding the implementation of the jointly agreed upon term caused frustration and mistrust amongst fishers, compromising future participation.

Published: May 2019

Abstract The present research employs the Ecological Risk Assessment (ERA) method to evaluate the probability of adverse effects in the water supply of Bom Repouso (MG), a city where the agriculture has caused an advanced degree of degradation of its sources. The methodology is based on the integration of different variables, divided into three Lines of Evidence (chemical, physical-chemical and ecotoxicological), and allows for the evaluation of risk assessment between 0.0 and 1.0 in the sampled environment. Five sampling points were evaluated in three periods, with the results varying between the four possible ratings (from low to very high), and it was not possible to identify a pattern of risk evolution between them. Thus, the method used proved to be efficient in assessing the degree of degradation of the environment, however, additional studies are required to improve this type of systemic impact assessment, based on the evaluation of the environmental degradation.
A gestão do conhecimento holística: delineamento teórico conceitual
Authors: Corrêa Fábio
Published: May 2019

Resumo Introdução: O paradigma holístico é anunciado para a Gestão do Conhecimento há décadas. No entanto, o delineamento teórico acerca desse paradigma para seu ajustamento junto a Gestão do Conhecimento se faz necessário. Isso porque o holismo têm admitido interpretações errôneas e seu uso em conjunto com a Gestão do Conhecimento pode resultar na percepção de que seja, apenas, abordar as empresas em sua completude, como foco no conhecimento. Objetivo: Este estudo objetivou delinear teoricamente o que consiste o paradigma holístico e o ajustar a Gestão do Conhecimento, anunciando, posteriormente, o conceito de Gestão do Conhecimento holística. Metodologia: Trata-se de uma pesquisa exploratória, por buscar esclarecer e delinear conceitos e ideias com vistas a municiar problemas pesquisáveis para estudos posteriores. Resultados: Como resultado a Gestão do Conhecimento holística é delineada teoricamente e conceituada. Isso tende a prover um alicerce para o desenvolvimento de pesquisas que considerem a Gestão do Conhecimento totalitária nas organizações. Conclusão: Conclui-se que a Gestão do Conhecimento holística é uma proposta que visa abordar as partes pelo todo, considerando que essas partes não devem ser analisadas de forma isolada por haver uma interligação entre essas e, portanto, resulta em recontextualizar essas partes num molde que contemple a totalidade.
