Interview with Thiago Rodrigo dos Santos, Molecular Microbiology Poster Award winner at 2nd Workshop in Microbial Molecular Biology in Campinas, Brazil.

Molecular Microbiology Poster Award—Thiago Rodrigo dos Santos, master's student at the University of São Paulo for their poster entitled ‘Characterization of an antibacterial Type IV Secretion System effector/inhibitor pair with nuclease activity in Xanthomonas citri’. My name is Thiago Rodrigo dos Santos. I have an undergraduate degree in biochemical engineering from the University of São Paulo (USP). And, I am a final year master's student at the Institute of Chemistry. Bacteria sharing the same niche must compete for nutrients and space. In this project, our goal was to understand the bactericidal type IV secretion system of Xanthomonas citri, an important phytopathogen that causes large damage to citrus crops. The type IV secretion system, which is part of a new family of type IV secretion systems, can transport several types of bactericidal proteins to the periplasm of other bacteria. I work under the supervision of Professor Shaker Chuck Farah, who is a pioneer in the study of this system. In this project, I worked with a putative effector-inhibitor pair of the type IV secretion system. Computational analyses predicted that this effector had nuclease activity, leading us to hypothesize that this effector acts as a toxin that degrades the target cell's DNA. We showed, by using heterologous expression, that the effector protein is toxic on microbial growth. Bacterial competition assays further showed that the effector confers a strong competitive advantage. Using a reporter strain, we then showed that the effector activates the E. coli DNA repair response, and that this protein can degrade plasmids in in vivo assays. We finally showed that the putative related inhibitor can suppress the activity of the effector, confirming that the proteins form an effector-inhibitor pair. After finishing my master's degree, I intend to continue developing studies with bacterial effectors. To this end, I intend to enroll in a doctoral program in biochemistry and molecular biology of microorganisms, probably in another research center, as this would allow me to have a greater variety of academic experiences.

Estratégias de uma universidade pública brasileira para comunicar a ciência na pandemia da COVID-19

A circularidade de informações, potencializada pelo avanço tecnológico e social de plataformas midiáticas, favorece o maior alcance de boatos, teorias conspiratórias e produtos comunicacionais que impactam, sobretudo, a ciência. Neste sentido, a pandemia do novo coronavírus mostra-se um evento histórico com importantes consequências para a humanidade e apresenta, dentre outros desafios, a necessidade de difundir informações credíveis que auxiliem no combate à disseminação da doença. Estudar como determinados conteúdos encontram eco a partir do uso das redes sociais abre caminhos para discutir como a comunicação pública da ciência se articula às narrativas em circulação nas redes. É a partir deste contexto que o presente estudo se apresenta, ao mapear as estratégias de comunicação em redes sociais virtuais implementadas pela Universidade de São Paulo (USP) que, de acordo com indicadores, figura como a maior produtora de pesquisa no Brasil e a segunda da América Latina. A análise de conteúdo das postagens do Facebook, publicadas durante os meses iniciais de registro de casos e mortes pelo vírus, de fevereiro a abril de 2020, buscou compreender a relação entre comunicação midiática e a responsabilidade de organizações que produzem ciência para combater a desinformação e movimentos negacionistas.

PISCICULTURA NA UNIVERSIDADE DE SÃO PAULO (CAMPUS DE PIRASSUNUNGA): UMA HISTÓRIA QUE NÃO FOI CONTADA

The aim of this paper is to recount the history of the first Fish Farming Station at the University of São Paulo (USP), Pirassununga Campus, an important instrument for consolidating aquaculture at the institution and for training specialized professionals, many of whom currently work in public and in the private sectors. The station was conceived during the administration of the Centre for Zootechnics and Livestock Industries Fernando Costa-Cizip, beginning the construction at the end of 1992, using the structure of the newly created of Pirassununga’s Campus, and was completed the following year, with the inauguration scheduled for August 1993, by the then rector of University of São Paulo. However, the Rector resigned his post eve of the inauguration, so the station was never formally inaugurated and its history was lost in the time.

A scientometric study of the molecular data on Brazilian red algae

The growth in the number of molecular sequences produced in recent years has provided valuable contributions to the knowledge diversity of red algae (Rhodophyta) in Brazil. However, many works indicate that there is still much to be studied. Here, we highlight the importance of compiling all these data to evidence possible taxonomic and geographic knowledge gaps in red algae through molecular data. So, this study presents a scientometric analysis of the molecular studies carried out on red algae in Brazil, based on the analysis of DNA sequences available in the public database GenBank. Our results demonstrated an increase in published papers from 1994 to 2020, corresponding to 165 studies analyzed. A huge disparity in the production of knowledge was observed, with the southeastern region concentrating the researchers responsible for most of the published studies, with emphasis on those in the University of São Paulo (USP). Bahia and São Paulo states stand out with the highest observed taxonomic richness, respectively. We also could identify the taxonomic groups with more molecular data generated, the sequence number deposited per institution since 1994, the main markers used, the regions that require a greater collection effort, and where the researchers who study red algae in the country are.

IAG/USP Test Site: A Near Surface Geophysics Teaching and Research Laboratory

This work shows the construction project of the Geophysical Test Site (Sítio Controlado de Geofísica Rasa, SCGR-I) of the Institute of Astronomy, Geophysics and Atmospheric Sciences (IAG), of the University of São Paulo (USP) and its impact on teaching and research in Geophysics. The IAG/USP test site (SCGR-I) has 1500 m2, being characterized by 7 studies lines with 30 m length in the NS direction. Targets, such as metallic pipes and tanks, plastic pipes and tanks, concrete tubes, ceramic pots, among others, with different geometries and physical properties were buried at depths from 0.5 to 2 m in relation to the surface. A metallic guide pipe of 3.8 cm diameter was buried at the 15 m position along the EW direction, crossing all 7 lines. Targets simulate objects found in archaeological studies, geotechnical and urban planning studies and environmental studies. In this work, comparative analyzes between real and synthetic GPR results on metallic and plastic tanks are shown, as well as EM38 results on metallic tanks. The SCGR-I proved to be an important tool for teaching and research related to the applications of geophysical methods for near surface investigations and could be a motivation to build more test sites.

Scientific Collaboration Network Views: A Brazilian Computer Science Graduate Programs Case

Scientific collaboration networks can present different views of researchers’ interactions. This work presents SCI-synergy, an online navigable artifact aiming to promote mechanisms and views of scientific collaboration networks. The artifact focuses on the researchers’ interaction in the co-authorship of publications considering intra- and interprogram relationships. SCI-synergy is developed upon the design science research paradigm using scientific publication data available on the large Digital Bibliography & Library Project (DBLP) repository. Official data from the Sucupira repository of six Brazilian graduate program members including Federal University of Minas Gerais (UFMG), State University of São Paulo (USP), Federal University of Rio Grande do Norte (UFRN), Federal University of Amazonas (UFAM), University of Brasília (UnB), and University of Vale do Rio dos Sinos (UNISINOS) is used. Data from these graduate programs illustrate the artifact usage regarding the scientific collaboration network of each program, how each researcher cooperates, and what relationship patterns exist in intra- and inter-programs views. We advocate that, even though it is necessary to consider data from each program’s history and current contextualization regarding politics, economics, and administration, the collaboration network views provided by SCI-synergy might help to understand collaboration network patterns.

Environmental Education in Science Clubs: An analysis of the papers presented at the EIC's workshop

Education is not a mandatory subject in the Brazilian curriculum, but official curricular documents and legislation in the field of education highlight its importance in the formation of the contemporary subject and, in addition, affirm that it must be worked in an integrated and transversal way within of educational institutions, either with the disciplines, as well as in projects. Thus, the objectives of this work were to analyze seven works presented at the Interactive Science Space (EIC) workshop. For this, scientific meetings were held with the students within the EIC Science Club, which lasted from April to August, and in the last three months, September to November, the students worked on the development of projects to present them in the workshop held on the premises from the University of São Paulo (USP). The main results showed that club members were concerned with environmental issues, decided to study them, and acquired a speech in favor of awareness of environmental causes.

Current approaches for preventing environment-associated contamination in healthcare facilities: a systematic literature review by open access database

This article presents a Systematic Literature Review (SLR) whose objective is to identify aspects related to the built environment of Emergency Rooms (ERs) and healthcare facilities that interfere with infection by respiratory diseases. The SLR presented is a relevant part of ongoing research dedicated to discussing the built environment’s role on contamination, considering the COVID-19 pandemic scenario and the ER of the University Hospital of the University of São Paulo (USP), sited in São Paulo city, Brazil, as a case study. The results of this SLR showed that the main aspects discussed in the selected articles are: Heating, Ventilation, and Air Conditioning (HVAC) systems; disinfection and hygiene; layout and spatial organisation; air curtain and air purification; natural ventilation; door opening; and surface material. As major findings, the importance of properly designed mechanical ventilation systems and of the parameters’ control for the maintenance of Indoor Air Quality (IAQ) are highlighted. In addition, the existence of isolation rooms; periodic assessments based on guides and protocols; self-sanitising materials surfaces; and environmental design strategies are presented, together with the development of technologies, often incorporated into hospital furniture. Thus, as contribution, the article highlights the importance of the association of several measures related to the performance of the built environment to minimise respiratory infections in healthcare environments. As a limit of this research, only open access articles and reviews from 2017 to 2021 were considered, so that the article reveals trends in this field of study, not covering the entirety of content.

A three-dimensionally printed otological model for cholesteatoma mastoidectomy training.

To relate the creation and expert validation (face and content validity) of an affordable three-dimensional (3-D) printed model of temporal bones with chronic otitis media with cholesteatoma (COMC) as a simulator for mastoidectomy. We performed computed tomography (CT) of the temporal bones of a patient with COMC followed at the University of São Paulo (USP) Hospital with 3-D Slicer to create a 3-D model of the affected bone using light-curing resin and silicone (cholesteatoma). The final 3-D printed images were scored by 10 otologists using a customized version of the Michigan Standard Simulation Scale Experience (MiSSES). Internal consistency and inter-rater reliability were assessed using Cronbach's α and intraclass correlations. Otologists consistently scored the model positively for fidelity, educational value, reactions, and the overall model quality. Nine otologists agreed that the model was a good educational device for surgical training of COMC. All experts deemed the model ready-or nearly ready-for use. The final cost of the model, including raw materials and manufacturing, was 120 USD. Using 3-D printing technology, we created the first anatomically accurate, low-cost, disease-reproducing 3-D model of temporal bones for mastoidectomy training for cholesteatoma.

Temporomandibular disorder in individuals with spinal cord injuries

Objective This study evaluated Temporomandibular Disorder (TMD) in individuals with Spinal Cord Injuries (SCI) compared to individuals without physical disabilities. Design Cross-sectional. Setting International Fair of Technologies in Rehabilitation and Accessibility (REATECH) and School of Dentistry at the University of São Paulo (USP), Brazil. Participants In total, 19 patients with SCI and 19 patients without SCI (36.9 ± 11.4 years old) were examined by a calibrated examiner. Methods using the following parameters: cervical spine mobility, palpation of muscle groups of the head and neck, functional manipulation of the lateral and medial pterygoids, and joint palpation (Diagnostic Criteria). The pattern and amplitude of mandibular movements were determined during screening using the Helkimo index. Statistical analyses Student's t-test, chi-square, Fisher's exact and Shapiro–Wilk test were used. Results The groups did not differ in the presence of noise, pain, temporomandibular joint palpation, locking, dislocation, jaw pain, muscle sensitivity, or in pain, mobility of the cervical spine and functional manipulation. With respect to the jaw mobility index, the groups differed in range of movement (P = 0.020) and maximum right lateral movement (P = 0.007), with the worst values in the SCI group. The groups also differed in relation to lateral flexion in cervical mobility, in which the group without SCI presented better results (P = 0.046). Conclusion The Spinal Cord Injuries group showed higher levels of TMD in terms of range of movement, lateral flexion, and maximum right lateral movement, than the individuals without physical disabilities, demonstrating a clinical significance between cervical and mandibular disability in this group.

Mobile drip irrigation (MDI): Clogging of high flow emitters caused by dragging of driplines on the ground and by solid particles in the irrigation water

Mobile drip irrigation (MDI) system is interesting because it combines the efficiency of drip irrigation with the versatility of center-pivot irrigation; however, experimental information about clogging of MDI emitters caused by dragging of driplines on the ground and by solid particles in the irrigation water simultaneously are not presented to date in the literature. The objective of this research was to evaluate the performance of high-flow MDI drippers regarding the clogging resistance of emitters from dragging driplines over different soil types (experiment 1) and regarding clogging resistance from solid particles in the irrigation water (experiment 2). The research was carried out at the Irrigation Material Testing Laboratory at the University of São Paulo (USP), Brazil. In experiment 1, dragging of driplines over ground for 3 soil types, for different dripper models under dynamic and static conditions, were tested. In experiment 2, driplines resistance to clogging by solid particles in the irrigation water was evaluated. Dragging of driplines over ground did not cause significant clogging of emitters (A and B) for the in dynamic conditions, with average relative flow rate of drippers above 97%; however, under static conditions, after 30 days of resting in the field, the average relative flow rate of drippers was close to 55%. In experiment 2, dripper models B and C were analyzed and showed relative flow rate averages > 70% up to 300 h when evaluated in all pre-filter positions tested. Dripper models B and C proved to be resistant to blockage by solid particles smaller than 125 µm in the irrigation water, regardless of dripper pre-filter orientation. With particles up to 212 µm in diameter, dripper model B with pre-filter facing down showed a 25% flow rate reduction. Over the 500 h of evaluation, emitter B with the pre-filter vertical and facing upwards, had the highest average relative flows of 98.2% and 94.6%, respectively, while emitter C gave the best performance with the pre-filter in a diagonal position (84.4% of average relative flow). The results obtained in this paper, showed a better resistance of high-flow MDI drip emitters (3–8 L·h−1) to solid particles in the irrigation water. These results are important because shows an effective clogging alternative by using high-flow emitters on MDI systems, what is the main disadvantage of low-flow emitters on traditional fixed drip irrigation systems in irrigated fields around the world.

THE INTERNATIONALIZATION OF BUSINESS SCHOOLS BASED ON FACULTY ACTIVITIES: EXPLANATIONS FROM THE SOCIAL EXCHANGE THEORY

ABSTRACT The internationalization of higher education has gained in theoretical and empirical importance in recent decades. In this context, this article aims to describe and analyze the internationalization of business schools from the activities of their academics and based on the propositions defended by the Social Exchange Theory (SET). To achieve our goal we conducted 39 interviews with academics from business schools in the United States and Brazil, including Massachusetts Institute of Technology (MIT), Harvard, Getulio Vargas Foundation (FGV) and University of Sao Paulo (USP). We found that: (i) there are individual rewards that are not addressed by SET; (ii) there are benefits to third parties not covered by SET; (iii) certain non-rational choices are not provided by SET; and (iv) the condition of equivalence between costs and rewards provided by SET has its weaknesses. With these findings we add theoretical and empirical contributions to our theme.

Soiling accumulation impact on PV modules installed at different tilted angles in São Paulo, Brazil

The present study was carried out at the University of São Paulo (USP), in the capital campus, in Butantã, São Paulo. On the rooftop of the Photovoltaic Systems Laboratory (LSF). This study used twenty photovoltaic modules with a unit power of 20 Wp. Before the beginning of the study, the modules were exposed to natural light so that they would suffer the LID effect. Subsequently, all modules were calibrated to measure the solar irradiance, using IEC 60904-2 using a pyranometer as a secondary reference sensor. After calibration, the modules were arranged in pairs, with angles ranging from 0 to 45° as reference to the surface, with a difference between pairs of 5°. To evaluate the influence of rainfall, which is the main responsible for the natural cleaning of the modules. The pluviometric values were obtained from the meteorological station of the Institute of Astronomy, Geophysics and Atmospheric Sciences of the USP. The module allocated at 0°, “Dirty” was used as reference and all the results obtained were calculated in relation to it. The results for the 18 months of experiment showed the non-linear influence of soiling, acting in a stronger way for the less inclined angles, and after 10°, this influence, became less relevant, in comparison to the previous angle. The largest losses were found for 0° and 5°, the losses exclusively to soiling were 8.16 % and 6.82 % respectively. For angles greater than 10°, the soiling effect was attenuated, which resulted in less significant losses, for 15° the difference between the impact of dirt compared to 10° was only 0.1%. Rainfall also had a very relevant impact on the experiment. This study concluded that the optimal angle, where dirt accumulation was reduced, the rainfall cleaning and relative gains were optimized is in the range between 20° and 30°.

Documentation Influence in Brazilian Library and Information Science: the Case of University of São Paulo

Johanna W. Smit studied under Jean Meyriat and Jean-Claude Gardin in France, and upon becoming a professor at the Library Science and Documentation Department of the School of Communication and Arts of the University of São Paulo (USP), Brazil, introduced to it the then current developments in French Documentation, mainly those related to documentary analysis. In 1986, Professor Smit and a group of professors of USP founded TEMMA Group, a research group devoted to issues concerning document organisation and representation, which lasted for 30 years and incorporated professors of São Paulo State University. In this paper, I present to a wider public the research related to document organisation and representation that was brought about by the professors of USP from 1981, when Johanna W. Smit became a professor. I focus on the research conducted by the members of TEMMA Group, presenting key concepts developed by them, how the studies of the group still influence USP, and the reason why their developments are relevant to current document studies.

Theatre and Indigenous Peoples: Learning to Imagine New Worlds in End Times

This article examines the relationship between the performing arts and Amerindian peoples, specifically the Araweté, Juruna/Yudjá and Kamayurá peoples, which belong to the Tupi branch, whom I met as part of postdoctoral research carried out from February 2018 to January 2019, at the University of São Paulo (USP). It analyses the conjuncture of the fight of Amerindian and riparian peoples before the destruction of the forest and rivers of the Amazon, based on case studies of two theatre performances: Altamira 2042, a scenic ritual instauration triggered by listening to the testimony of the Xingu river about the Belo Monte dam, and Os Um e Os Outros (The One and the Others), loosely based on The Horatians and the Curiatians by Bertolt Brecht.
