Nursing and self-care in the world of psychiatric care

Objective: Understanding self-care among nursing professionals in mental health. Method: qualitative study conducted in a psychiatric unit of a teaching hospital in Rio Grande do Sul, Brazil. Merleau-Ponty's phenomenology of perception was used as a philosophical theoretical framework and Paul Ricoeur's hermeneutic phenomenology was used as a methodological framework. The research was conducted with 10 nursing professionals in mental health, out of a total population of 15 professionals, by means of open interview, within the period from September to December 2010. Results: through the metaphor of discourses, the theme emerged: the world of psychiatry. Conclusion: care in the world of psychiatry is unveiled as a stage of intense interpersonal exchanges, matches and mismatches with the other involved in care. This space of objective and subjective relationships and events interferes with care for the other and each nursing professional's self-care

Semi-automatic rubble counting system for superheated droplet detectors

Neutron dose rate measurements are normally performed by means of PADC, CR-39 and TLD detectors. Although, none of these devices can give instant reading of the neutron dose, recently new kind of detectors are being developed, based on the formation of tiny drops in a superheated liquid suspended in a polymer or gel solution, called superheated droplet detector (SDD) or also as bubble detectors (BD), with no response for gamma radiation. This work describes the experimental setup and the developed procedures for acquiring and processing digital images obtained with bubble detector spectrometer (BDS), developed by Bubble Technology Industries, for personal neutron dosimeter and/or neutron energy fluence measurements in nuclear facilities. The results of the neutron measurements obtained during the F-18 production, at the RDS-111 cyclotron, are presented. These neutron measurements were the first ones with this type of BDS detectors in a particle accelerator facility in Brazil and it was very important to estimate neutron dose rate received by occupationally exposed individuals

Volume fraction calculation in multiphase system such as oil-water-gas using neutron

Multi-phase flows are common in diverse industrial sectors and the attainment of the volume fraction of each element that composes the flow system presents difficulties for the engineering process, therefore, to determine them is very important. In this work is presented methodology for determination of volume fractions in annular three-phase flow systems, such as oil-water-gas, based on the use of nuclear techniques and artificial intelligence. Using the principle of the fast-neutron transmission/scattering, come from an isotopic 241Am-Be source, and two point detectors, is gotten measured that they are influenced by the variations of the volumec fractions of each phase present in the flow. An artificial neural network is trained to correlate such measures with the respective volume fractions. In order to get the data for training of the artificial neural network without necessity to carry through experiments, MCNP-X code is used, that simulates computational of the neutrons transport. The methodology is sufficiently advantageous, therefore, allows to develop a measurement system capable to determine the fractions of the phases (oil-water-gas), with proper requirements of each petroliferous installation and with national technology contributing, possibly, with reduction of costs and increase of productivity

Teste de dois pontos estáticos para análise da percepção sensorial relacionada ao nervo alveolar inferior / Two-point static test for analysis of sensory perception related to the inferior alveolar nerve

Na odontologia algumas das principais complicações estão ligadas às injúrias nervosas sendo na maioria dos casos ligadas ao nervo alveolar inferior e oriundas de traumas, procedimentos cirúrgicos ou manipulações endodônticas. As avaliações da percepção sensorial das áreas inervadas pelo nervo alveolar inferior só podem ser realizadas através de testes subjetivos, relativamente objetivos e puramente objetivos como exemplo os questionários, o toque leve estático e o teste elétrico pulpar, respectivamente. Nos últimos anos tem-se desenvolvido técnicas e métodos de Teste Quantitativo da Sensibilidade (TSQ) para o melhor entendimento acerca da sensibilidade e dor orofacial. Testes alternativos que apresentam escalas de acompanhamento já são utilizados pela medicina para mensurar a evolução de pacientes com distúrbios neurossensoriais: O teste de Monofilamentos de Semmes-Weinstein e Discriminação de dois pontos estáticos. Então, levando-se em consideração a necessidade do aprimoramento do diagnóstico de possíveis alterações sensoriais na face, essa pesquisa tem o objetivo de avaliar os níveis se sensibilidade facial ao toque de dois pontos estáticos de pacientes submetidos á anestesia do nervo alveolar inferior. 

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Study of K-40, Ra-226, Ra-228 and Ra-224 activity concentrations in some seasoning and nuts obtained in Rio de Janeiro city, Brazil

Abstract This work presents an investigation of the activity concentration (AC) of naturally occurring radionuclides in 26 samples of seasoning and nuts utilized for Brazilian population. The samples were measured using gamma spectroscopy technique with a high-purity germanium detector. The analysis shows that K-40 AC was measured in all samples, and its AC ranges from 21.0 Bq/kg to 1288 Bq/kg. The highest K-40 AC was measured for cheiro verde, a Brazilian seasoning made of chives (Allium schoenoprasum) and parsley ( Petroselinum crispum), while annatto, made with the fruit of Bixa orelhana , presented the lowest AC. Brazil nut (Bertholletia excelsa ) presented the highest AC for Ra-226 and Ra-228 with 24 Bq/kg and 25.7 Bq/kg, respectively, and black pepper (Piper nigrum) presented the highest Ra-224 AC, with 33.9 Bq/kg. Behavior of radionuclides present in the seasoning samples and dose percentage due to ingestion was evaluated. The highest effective dose for members of the public due to idealized intake of 1 kg of seasoning was 23.5 µSv/y due to Brazil nut and the lowest effective dose was found for annatto: 0.13 µSv/y. The Syrian seasoning was the only sample that presented a measurable amount of Cs-137, (6.1 ± 1.1) Bq/kg for AC and 0.08µSv/y for effective dose
