title: Molecular identification and microbiological evaluation of isolates from equipments and food contact surfaces in a hospital Food and Nutrition Unit

description: Abstract The hygienic and sanitary control in Food and Nutrition Units (FNU) is considered a standard procedure to produce adequate meals and reduce the risk of foodborne diseases and hospital infections. This study aimed to evaluate the isolation and identification of bacteria from equipment and food contact surfaces in a hospital FNU as well as to evaluate the sanitary condition. Likewise, it was analyzed the adhesion of the microorganisms on polyethylene cutting boards. The presence of aerobic mesophilic microorganisms, yeasts, molds, coagulase-positive staphylococci, coliform and fecal coliform, and Escherichia coli were analyzed on eating tables, countertop surfaces and cutting boards used for meat or vegetable handling, and equipment such as microwaves and refrigerators. The molecular identification it was done by 16S rRNA gene sequencing. The adhesion of the microorganisms (biofilm formation) on meat and vegetable cutting boards was also evaluated by scanning electron microscopy. The results showed high numbers of all microorganisms, except for E. coli , which was not observed in the samples. The molecular analysis identified species of the Enterobacteriaceae family and species of the Pseudomonadaceae family. Scanning electron microscopy analyses revealed bacterial adhesion on the cutting board surfaces. The results obtained in this study indicated that the hygienic conditions of surfaces like plastic cutting boards and equipment in this hospital FNU were inadequate. The achievement and application of standard operating procedures could positively help in the standardization of sanitary control, reducing the microbial contamination and providing a safe food to hospitalized patients.

title: Pollen as a component of the diet of Doru luteipes (Scudder, 1876) (Dermaptera: Forficulidade)

description: Abstract The properties of maize pollen in the diet of Doru luteipes were determined by biological responses of the predator feeding on natural preys and artificial diet. The biological parameters of D. luteipes fed on Spodoptera frugiperda (Smith, 1797) eggs, maize pollen, Rhopalosiphum maidis (Fitch, 1856) + maize pollen and R. maidis were assessed. The effect of pollen on artificial diet on the biological variables of the predator nymphs and adults were also evaluated. Time span of nymphal development was greater for D. luteipes exclusively fed on earwigs, with the lowest rate of nymph survival. However, maize pollen plus earwigs in the diet provided the predator´s highest survival rate, whilst percentage of fertile females was double when fed on diets composed of S. frugiperda and R. maidis eggs. Development period decreased when D. luteipes nymphs consumed artificial diet plus pollen but there were high fecundity rates (number of laying/female and total egg/female) and a greater percentage of fertile females when they were fed on maize pollen.

title: SUSCEPTIBILITY TO ILLNESS OF PRIMARY TEACHERS IN OLINDA: SYMPTOMS, COMPLAINTS AND DIAGNOSES

description: ABSTRACT: Analysis of the multi-causality of the phenomenon of malaise and sickness of the teachers of the first letters under the physical, psychological and social aspects. The research was done from the perspective of the teachers, considering the possible consequences. The results were obtained through qualitative research with 32 teachers in three municipal schools in Olinda - PE, Brazil. The main objective was to discover and relate the main complaints, symptoms and diagnoses exposed in semi-structured questionnaires. We discovered multiple causes, frequent and recurrent, that provoked this phenomenon, originating in the teaching practice and producing malaise. Among these, we identified insomnia, voice and spine disorders, irritability, physical and mental fatigue, tension, anxiety, and depression. We observe that public policies, directed to this working class responsible for the foundation of the formation of the subject, are urgent and indispensable.

title: PIBID AND INSERTION IN TEACHING: EXPERIENCES, POSSIBILITIES AND DILEMMAS

description: ABSTRACT: This article results from a research investigating the contribution of the Institutional Program of Initiation to Teaching Scholarship (PIBID) for teaching formation for the early years of education. From a qualitative approach, we collected data in documental sources and in oral narratives of nine students of Mathematics, Biology and Chemistry courses and of three teachers from the institution that was locus of this research. The results indicate that the PIBID has contributed significantly to the teaching of the trainees because it stimulates immersion in diverse activities of teaching formation and initiation to research. However, vulnerabilities were observed, such as the absence of effective practices of the trainees with students of basic education, lack of pedagogical formation of the trainers and inexperience with research and teaching in basic education.

title: COMPARISON OF TWO INHALATIONAL TECHNIQUES FOR BRONCHODILATOR ADMINISTRATION IN CHILDREN AND ADOLESCENTS WITH ACUTE ASTHMA CRISIS: A META-ANALYSIS

description: ABSTRACT Objective: To compare the efficacy of pediatric asthma treatment by nebulizer and metered-dose inhaler with the use of a spacer (MDI-spacer) in rescue techniques for asthmatic patients assisted at pediatric emergency units. Data sources: A systematic review was conducted to identify the most relevant randomized controlled trials comparing the administration of a bronchodilator (β-2 agonist) by two inhalation techniques (nebulization and MDI-spacer) to treat asthma in children at pediatric emergency units. The following databases were searched: PubMed, Scientific Electronic Library Online (SciELO), and ScienceDirect. Two researchers independently applied the eligibility criteria, and only randomized controlled trials that compared both inhalation techniques (nebulization and MDI-spacer) for asthma treatment at pediatric emergency units were included. Data synthesis: 212 articles were pre-selected, of which only nine met the eligibility criteria and were included in meta-analysis. Results show no differences between inhalation techniques for any of the four outcomes analyzed: heart rate (difference - Df: 1.99 [95% confidence interval - 95%CI -2.01-6.00]); respiratory rate (Df: 0.11 [95%CI -1.35-1.56]); O2 saturation (Df: -0.01 [95%CI -0.50-0.48]); and asthma score (Df: 0.06 [95%CI -0,26-0.38]). Conclusions: The findings demonstrate no differences in cardiorespiratory frequency, O2 saturation, and asthma scores upon administration of β-2 agonist by both inhalation techniques (nebulization and MDI-spacer) to asthmatic patients assisted at pediatric emergency units.

title: THE SPACE OF CHEMISTRY IN THE BRAZILIAN SCIENCE CENTERS AND MUSEUMS

description: There are several consequences of the negative or poor perception that society tends to maintain with Chemistry like the lack of interest of students in considering Chemistry as a career or the university dropout rates. Given the importance of museums and science centers to contribute to scientific education and arouse people’s interest in science, this article presents a research carried out with Brazilian science centers and museums to appraise the space of Chemistry in non-formal places of Education. The results obtained are similar to some international data showing the amount of chemistry-related content in museums is insufficient, not exceeding the 40% rate. Most of the activities are aimed at supporting formal education by offering courses for teachers and students through the use of laboratories or conducting experiments when there is available monitoring. Chemistry can be considered in the development of science museums exhibitions and, with the guidance of scientists, it can be shown and discussed without creating distorted visions, sensationalism or conceptual misconceptions.

title: Crestbond shear connectors for load transfer in concrete filled tube columns

description: Abstract This paper presents an experimental study with numerical modeling of Crestbond shear connectors in concrete filled tube columns. The Crestbond, which consists in a steel plate with regular cuttings, was originally conceived for composite beams and is now being proposed as an alternative device for load introduction and shear transfer at the steel-concrete interface in concrete filled tube columns. The results achieved in this work were very favorable to the new application proposed for the connector as high values of shear strength were obtained. Moreover, the numerical and experimental results enabled comparative analysis and investigations regarding the influence of concrete conditions and the geometry of the column section on the mechanical properties of the connector.

title: The potencial influence of rice husk ash in self compacting mortar: cases of mechanical strength and water absorption

description: ABSTRACT The study presents an experiment on the use of rice husk ash (R.H.A) for the production of self-compacting mortars. For this purpose, CPZ II 32 cement, natural sand, industrialized rice hull ash, electrostatic and steric performance superplasticizer, and water were used. Two types of mortars were produced, one series to be densified with the aid of vibration, and another series with the incorporation of R.H.A in the 35% content in relation to the mass value of the cement, and of superplasticizer, to be made strong by the action of its own weight. The values of water/cement ratio were 0.4, 0.5 and 0.6 for cases of vibrated mortars and 0.68, 0.63 and 0.55 for cases of self-compacting mortars. For the vibrated mortars were performed in the fresh state the consistency tests with aid of the table of blows, slump tests, and the evaluation of the apparent specific mass. For the self-compacting mortars, the slump flow tests were carried out in the fresh state and the flow test confined with the aid of the funnel; besides the evaluation of the apparent specific mass. In the hardened state the tests of compressive strength and diametrical compressive strength, and of water absorption were realized at 7, 28, 60 and 90 days of cure. It was observed that the mortars with the addition of R.H.A and the vibrated ones presented mobility conditions compatible with respect to each case and absence of segregation; The mortars with R.H.A presented mechanical strength values slightly higher than those presented by vibrated mortars, as well as lower absorption values, despite the higher values for the "water / cement" ratio compared to the cases of vibrated mortar.

title: Photographic views of railroads: recording public works in nineteenth-century Brazil

description: Abstract This article analyzes how railway engineering was connected to the production of photographs in mid-nineteenth-century Brazil. The hypothesis is that growing demands related to the execution of projects and new cartographic knowledge required more visual records, which was supplied and leveraged with the emergence of photographic techniques. Data was collected on photographic records of railroads taken in Brazil after the 1850s to analyze the characteristics of these images. This analysis was further extended in a series of photographs by Marc Ferrez, since this collection contains the most views of railways currently accessible, permitting the recognition of patterns in these images to identify them as “photographic project records.”
