ANÁLISE DE RISCOS DO EMISSÁRIO SUBMARINO PARA O DESCARTE DE ÁGUA PRODUZIDA

O destino das águas produzidas, que são oriundas de reservatórios de hidrocarbonetos, é uma questão a ser tratada pelas empresas de E&P, pois são enquadradas como efluentes industriais. Dentre as alternativas utilizadas para o seu destino está o descarte por emissários submarinos. Neste trabalho foi realizado um estudo para mapear os riscos e qualifica-los, de forma a direcionar para as medidas mitigadoras que devam ser condicionadas a tais elementos. A metodologia consistiu em um método investigativo e revisão da literatura, para avaliar as condições padrões dos projetos e características das águas produzidas. Os resultados demonstraram que a alternativa de descarte da água produzida por meios de emissário submarinos podem ser uma alternativa eficaz, se assim a mesma atender os padrões de lançamentos de efluentes dentro da Resolução CONAMA430/2011, pois a maior parte dos riscos ambientais foi identificada no processo de tratamento de efluentes (ETE).

Neuroticism, stress, and rumination in anxiety and depression of people with Vitiligo: An explanatory model

Psychological impacts of Vitiligo have been demonstrated, and associations of the skin disease with anxiety and depression disorders have already been shown. However, it is still unclear the role of individuals’ personality factors, such as neuroticism, stress, and rumination, as well as sociodemographic characteristics of people with Vitiligo in such disorders. We conducted a study in a community sample of individuals with Vitiligo (N = 324) aiming to test the hypothesis that neuroticism, stress, and rumination are subjacent to these individuals’ anxiety and depression symptomatology. We also explored whether individuals’ gender might favor the onset or wors- ening of the psychological consequences of such disorders. Results showed that the relationship between neuroticism, anxiety and depression was mediated by stress and rumination (brooding), being this effect moderated by the participants’ gender. Specifically, women’s reflection and stress seemed to be important mechanisms to predict their anxiety and depression symptoms, whereas brooding predicts such disorders’ symptomatology in men with Vitiligo. These findings may guide future research and clinical interventions for this population, for which it is necessary to consider the psychological consequences of the disease and not just its physiological aspects.info:eu-repo/semantics/publishedVersio

Suscetibilidade in vitro de dermatófitos a azóis pelos métodos macro e microdiluição em caldo

The in vitro susceptibility of dermatophytes to the azole antifungals itraconazole, fluconazole and ketoconazole was evaluated by broth macro and microdilution methods, according to recommendations of the CLSI, with some adaptations. Twenty nail and skin clinical isolates, four of Trichophyton mentagrophytes and 16 of T. rubrum were selected for the tests. Itraconazole minimal inhibitory concentrations (MIC) varied from < 0.03 to 0.25 µg/mL in the macrodilution and from < 0.03 to 0.5 µg/mL in the microdilution methods; for fluconazole, MICs were in the ranges of 0.5 to 64 µg/mL and 0.125 to 16 µg/mL by the macro and microdilution methods, respectively, and from < 0.03 to 0.5 µg/mL by both methods for ketoconazole. Levels of agreement between the two methods (± one dilution) were 70% for itraconazole, 45% for fluconazole and 85% for ketoconazole. It is concluded that the strains selected were inhibited by relatively low concentrations of the antifungals tested and that the two methodologies are in good agreement especially for itraconazole and ketoconazole.Foi avaliada a suscetibilidade in vitro de dermatófitos aos antifúngicos itraconazol, fluconazol e cetoconazol, pelos métodos macro e microdiluição em caldo, de acordo com as recomendações do CLSI, com algumas modificações. Foram estudados 20 isolados clínicos de lesões de unha e pele, sendo quatro Trichophyton mentagrophytes e 16 T. rubrum. A concentração inibitória mínima (CIM) para itraconazol variou de < 0,03 a 0,25 µg/mL pelo método da macrodiluição, e de < 0,03 a 0,5 µg/mL pela microdiluição em caldo; de 0,5 a 64 µg/mL e de 0,125 a 16 µg/mL para fluconazol, respectivamente, pela macro e microdiluição; e de < 0,03 a 0,5 µg/mL por ambos os métodos para cetoconazol. A concordância entre os dois métodos (considerando ± uma diluição) foi de 70% para itraconazol, 45% para fluconazol e 85% para cetoconazol. Conclui-se que os isolados estudados foram inibidos por concentrações relativamente baixas dos antifúngicos testados, e os dois métodos apresentam boa concordância, especialmente para itraconazol e cetoconazol

Toxicity of Fenpyroximate, Difenoconazole and Mineral Oil on Apis mellifera L. Introduction

Bees of genus Apis are the main crop pollinators; however, the use of pesticides in agriculture may intoxicate them during foraging. In this study, we evaluated the toxic eff ects caused by difenoconazole (fungicide), fenpyroximate (acaricide) and mineral oil (adjuvant) used alone and associated (pesticide + adjuvant) on workers of Apis mellifera L. Bees were exposed to product doses recommended by manufacturers, orally and in contact on a contaminated surface in a controlled environment. All products presented low lethality, both in isolation and combination (except for difenoconazole via contact), however, they all showed toxic effects. The results showed that combination of pesticides with adjuvant augmented toxic eff ects

Peer Assessment in the Context of Team-Based Learning in Undergraduate Education: How Far Can We Go?

In medical education, the team-based learning method (TBL) is a teaching strategy used to intensify interactive learning in small groups, in which the student is given the role of evaluating his/her peers - peer assessment (PA). To investigate the interference of the students' interpersonal relationships in awarding their peers grades (''halo effect''). A qualitative and quantitative retrospective study. The study participants were 78 first-year medical students, divided into 17 teams for the TBL. The final grade of the PA for each member was calculated by the average of the grades received from their peers. Results: The comparison between the average of the evaluations in the TBL method (MTBLs) and the PA showed that 17.64% of the teams showed a significant difference between the grades, thus having the “halo effect”. In the qualitative analysis, the “halo effect” was evidenced in only one of these teams. Although many studies corroborate the idea that using PA in the formative assessment is appropriate, advancing in the use of PA in the summative assessment is necessary, integrating it into the institution's evaluation system. Data presented here can help in continuing its use and in increasing its reliability

Resiliência como fator de proteção aos transtornos mentais menores na equipe de enfermagem

OBJECTIVES: To track the presence of minor mental disorders and levels of resilience in nursing professionals who work in emergency services and inpatient units, as well as to verify possible associations between these variables and sociodemographic and professional characteristics. METHODS: Descriptive, correlational and cross-sectional study consisted of 203 nursing professionals (nurses, nursing technicians, and nursing assistants), from the country side of São Paulo State. Data collection was performed using a sociodemographic and professional characterization instrument and the Brazilian version of the Self-Report Questionnaire (SRQ-20) and the resilience scale. RESULTS: The overall prevalence of minor mental disorders among the participants was 31%, being lower among older professionals and men. The resilience of the professionals was high, with mean values ​​of 136.4 (±20.1) points. Older professionals and those who worked in emergency units had higher resilience scores. Lower resilience scores are associated with a greater possibility of minor mental disorders in this study.

Are we teaching patient safety to our academics? : The experience of a course in the countryside of São Paulo

Nowadays, one of the biggest concerns in the health care field is centered on patient safety with a primary focus on the errors of the medical team. In 2009, WHO created a guide for universities aimed at patient safety in which it suggests new ways of approaching patients, thus improving the quality of trained professionals and dramatically reducing adverse events. There is a consensus that there is a restructuring of a system that currently presents serious failures that result in permanent harm to the objective of the medical team, which is the well-being of the patient, as well as an efficient inspection of the Decree Number 529/13 in Brazilian universities. It is in this context that the present work proposes to highlight the gap currently existing in Brazilian universities, based on the sampling of one of them, located in the countryside of São Paulo. Prospective intervention study using a quantitative and qualitative methodology, carried out in two stages: analysis of teaching plans and application of the quantitative and qualitative perception instrument to professors. Was not found in the teaching plans of the modules of the medical course at Universidade Brasil the concept of patient safety. Semi-structured questionnaire was answered by 47 teachers, 11 (23.4%) of the basic cycle and 36 (76.6%) of the clinical cycle and internship. Professors at Universidade Brasil consider that the themes are extensivily addressed in their classes, although they are not described in most of the modules\u27 teaching plans. Medical education in Brazil needs a qualitative leap, and that leap is certainly in the area of patient safety.  In the context of implementation, the multiprofessional edition of the World Health Organization (WHO) patient safety curriculum guide can be used as guidance and a current and very promising development in relation to the acquisition and examination of the skills necessary for safe care for the patient is the establishment of interprofessional training wards. Considering that medical students are the future driving force of change in health care, it is necessary to encourage quality improvement and patient safety education to offer the patient-centered. The graduation, at any time and since day one, is the moment of formation, therefore favorable to the teaching of this topic for students in the health care field, and all teachers should be involved with these contents.

Blended Learning Methods in Specialization Graduate Courses Improve the Knowledge Gain Metric

Information and communication technologies (ICT) have been proven beneficial in teaching of health sciences courses. Combined e-learning strategies with face-to-face activities, among others, are defining characteristics of a new learning perspective called blended learning methods. The paucity of data to confirm the benefits of online forms of learning, in isolation or as a part of a blended learning method, indicates that more studies are still required to assess their influence on the teaching-learning process. This study measured knowledge gained using face-to-face (FtFA) and distance educational on virtual learning environments (DA-VLE) strategies in health sciences. For two consecutive years, FtFA and DA-VLE education strategies were used in a discipline of specialization graduate course, each discussing two topics. The knowledge gained using each strategy was assessed for each topic using a pre (PT) and post-test (PoT). The performance frequency (PF) of participants was categorized based on the number of correct answers in each assessed. The PF frequency increased between the PA and PoT in both strategies (FtFA and - DA-VLE), although higher scores were observed in DA-VLE strategies when compared to FtFA strategies. These data indicate that such strategies, within this context, are vital, and can bring benefits to the teaching-learning process in combination

Peer-Assisted Learning: A New Look at the Good Old Monitoring and Its Motivation from the Perspective of Student-Monitor

Peer-assisted learning (PAL), good old monitoring, has been used in medical schools and shown good results in professional development and in developing communication skills among students. This method provides mutual benefits for both monitors/near-peer teachers - NPT and monitored students; however, little is still known about the NPT’ perception about peer-assisted learning. To evaluate the real motivation of students to become NPT, and to investigate how NPT qualify their own teaching activities – such as productivity, performance and difficulties faced – seems to be a crucial step for implementing PAL in medical schools. The research instrument, a semi-structured questionnaire with 11 closed questions and 3 questions that allowed the answer “other” and further explanation, was answered by 26 medical students, NPT of basic disciplines. The results showed a positive effect of PAL on the teaching-learning process, and the real reasons of students to become NPT and the positive impacts of PAL on their academic life. The identification of these potential benefits should encourage medical schools to promote training so students can perform their role as NPT since PAL aids in the development of their clinical and pedagogical skills

Selective suppression of {112} anatase facets by fluorination for enhanced TiO2 particle size and phase stability at elevated temperatures

Generally, anatase is the most desirable TiO2 polymorphic phase for photovoltaic and photocatalytic applications due to its higher photoconductivity and lower recombination rates compared to the rutile phase. However, in applications where temperatures above 500 °C are required, growing pure anatase phase nanoparticles is still a challenge, as above this temperature TiO2 crystallite sizes are larger than 35 nm which thermodynamically favors the growth of rutile crystallites. In this work, we show strong evidence, for the first time, that achieving a specific fraction (50%) of the {112} facets on the TiO2 surface is the key limiting step for anatase-to-rutile phase transition, rather than the crystallite size. By using a fluorinated ionic liquid (IL) we have obtained pure anatase phase crystallites at temperatures up to 800 °C, even after the crystallites have grown beyond their thermodynamic size limit of ca. 35 nm. While fluorination by the IL did not affect {001} growth, it stabilized the pure anatase TiO2 by suppressing the formation of {112} facets on anatase particles. By suppressing the {112} facets, using specific concentrations of fluorinated ionic liquid in the TiO2 synthesis, we controlled the anatase-to-rutile phase transition over a wide range of temperatures. This information shall help synthetic researchers to determine the appropriate material conditions for specific applications
