Níveis de proteína bruta na dieta para pós-larvas de camarão branco do pacífico em sistema de bioflocos

TCC (graduação) - Universidade Federal de Santa Catarina. Centro de Ciências Agrárias. Curso de Engenharia de Aquicultura.Avaliou-se índices zootécnicos de pós-larvas de Litopenaeus vannamei alimentadas com dietas contendo diferentes níveis de proteína bruta (PB), 31,28, 36,29, 41,57, 46,34 e 51,74 g.100g-1, bem como os parâmetros de qualidade de água, durante a fase berçário em sistema de bioflocos. Foram utilizados quinze tanques de 400L mantidos em sala com iluminação artificial (12/12) e equipados com sistema de aquecimento de água (28,14±0,5°C), aeração (O2>5mg.L-1) e substrato artificial (Needlona®). Os tanques foram povoados com camarões com peso médio de 0,018g em densidade de 3000 PL.m-3. A alimentação foi fornecida quatro vezes ao dia (20% da biomassa de cada tanque), sendo ajustada com biometrias semanais e ocasionalmente conforme o consumo. O experimento teve duração de 21 dias. O nível de proteína nas dietas não interferiu nos índices zootécnicos, não havendo diferença entre tratamentos. Em contrapartida, para compostos nitrogenados, os tratamentos com maiores níveis proteicos na dieta (46,34 e 51,74 g.100g-1) apresentaram níveis mais altos tanto para amônia quanto para nitrito, sendo os maiores consumos de açúcar também encontrados para esses tratamentos. O tratamento com maior inclusão de PB, 51,74 g.100g-1, apresentou menor valor para alcalinidade em relação ao tratamento com menor inclusão, 31,28 g.100g-1de PB. Para os dois tratamentos mais proteicos, os quais foram também os que apresentaram no geral menores alcalinidades, foi observado maior incorporação de cal hidratada. Assim, concluiu-se que pós-larvas de L. vannamei podem ser cultivadas em sistema de bioflocos alimentadas com menor quantidade de proteína na dieta (31,28 g.100g-1) sem comprometer os índices zootécnicos e reduzindo o risco de concentrações tóxicas de compostos nitrogenados

A política em Hannah Arendt: ambiente, lugar por excelência do fenómeno político

Tese de mestrado,Filosofia da Natureza e do Ambiente, apresentada à Faculdade de Letras da Universidade de Lisboa, 2008“O que estamos a fazer?” – questão que se coloca após tomarmos consciência que vivemos em colisão com o sistema ecológico do planeta. A mesma questão impôs-se a Hannah Arendt quando, na vivência dos tempos sombrios do século XX, verificou que a humanidade vivia em conflito consigo própria. Arendt é uma pensadora do começo. Neste contexto, e porque a crise ambiental é uma questão pública e política que se impõe, com Arendt procurámos o sentido das duas categorias, visando resgatar uma nova cidadania consciente da sua pertença ao mundos natural e humano, a partir da qual encontre uma via de recuperação dos mesmos. Assim, tendo por base a análise arendtiana da tripla dimensão da vita activa, labor, trabalho e acção, interpretámos o pensamento de Arendt sob duas perspectivas: na vertente política, porque encerra em si a possibilidade do novo e convoca a participação de todos, e na vertente ambiental, enquanto contexto promotor da acção política. Ambas revelam uma pensadora pioneira na interpretação da sociedade de risco e comprovam que a asfixia do planeta não é indiferente à crise civilizacional. The Human Condition (1958) é o livro de referência, embora toda a obra concorra para a tese que propomos: o Ambiente como lugar, por excelência, do fenómeno político. O cinema, enquanto arte política, tem aqui espaço. Surge através da interpretação dos filmes Notre Musique de Godard (2004) e An Inconvenient Truth de Al Gore (2006), que confirmam a actualidade do pensamento arendtiano e consolidam a nossa reflexão. Embora em contextos diferentes, estes autores partilham com Arendt o apelo ao regresso ao mundo e à Terra através da acção pública e política. Apelo que reforçamos.ABSTRACT:“What are we doing?” – a question that we ask after we become conscience that we live in collision with the planet’s ecological system. The same question was faced by Hannah Arendt when, in the XX century dark times, she realized that mankind was living in conflict with itself. Arendt is a thinker of beginnings. In this context, and because the environmental crisis is a public and political question in existence at this time, with Arendt we look for the meaning of these categories, to create a new citizenship conscience of the sense of belonging to the planet and man’s world, and by this sense of belonging recognizes the way to recuperate these. In this way, based on the analysis of the triple dimension of vita activa – labor, work, action – we look at Arendt’ works in two lights: in the political context, because it contains the possibility of the new and it requests the participation of all; and in the environmental context, while a promoter of the political action. Both reflect a pioneer thinker of society at risk and prove that the planet’s asphyxiation is not indifferent to the civilization crisis. The Human Condition (1958) is our reference to the thesis proposed: the environment as the place where the political phenomena could occur. Cinema, although a political art, has its own place in this thesis. It is displayed here in two current movies, Notre Musique from Godard (2004) e An Inconvenient Truth from Al Gore (2006), that confirms the actuality of Arendt’ thinking and consolidates our reflection. Although in different contexts, these authors share, with Arendt, the appeal to return to the planet and man’s world through political and public action. We share the same call

Organizational innovation : research into the information / training paths of decision-makers within hospitals

Innovation is fundamental for the development of any organization, being achieved not only through the new products/services and the renewed processes offered, but also through managerial practices. In order to introduce innovative practices, an organization should adopt a managerial model of innovation that includes organizational innovation processes based on professional competences, people manage­ment skills and their influence on the decision-making process. It is with this in mind that we propose a model that provides room for reflection on the reality of the health service organization. The model allows us to conclude that the path to be followed by these health units in the public health sector will be a long and arduous one if they are to achieve an efficient implementation of the innovation process at the knowledge level of professions, together with a real and effective organizational performance

Managers’ Competences in Private Hospitals for Investment Decisions during the COVID-19 Pandemic

The COVID-19 pandemic has posed an unprecedented challenge for health systems worldwide. The increased demand for investment in hospitals has become one of the greatest financial vulnerabilities, and in this context, the manager’s involvement in decision-making is associated with better analysis in order to achieve better results. This article aims to define a model to outline the manager profile in private hospitals, as well as the process and the relationship with investment decision-making, so as to guide future work to improve institutions’ performance and ensure the sustainability of patient care processes and the use of resources. Semi-structured interviews were held with an administrative (or financial) director in Brazil, Canada and Portugal and analyzed by the conventional content analysis method and coded, using NVivo 11, identifying the main topics. A model for investment decision-making is proposed to improve resource allocation and performance. The results indicate, for multidisciplinary training, where managers contribute to an efficient use of resources and contribute to the maintenance of quality of care, including about investment and financing of hospitals, where performance analysis reflects on decision-making.info:eu-repo/semantics/publishedVersio

Lead bioremoval by cork residues as biosorbent

The intensification of industrial activity during the last few years has greatly contributed to the increase of heavy metals in the environment, mainly in the aquatic systems [1]. Conventional technologies traditionally used for the removal of heavy metals from aqueous solutions are expensive and inefficient at low metal concentrations [2]. Biosorption, which is a property of different types of biomass (biosorbents) to bind and concentrate heavy metals from even very dilute aqueous solutions, is one of the most promising technologies that can be used for this purpose [3]. The goal of this work was to study the bioremoval process of Pb(II) ions from aqueous dilute solutions by cork granulates (1-2 mm) from a Portuguese cork processing company. The effect of physico-chemical parameters such as initial metal solution, pH, biomass cork pre-treatments and initial metal and biosorbent concentrations on the metal removal efficiency were investigated. The maximum Pb(II) uptake capacity (Qmax) of cork biomass was also determined from the Langmuir isotherm. The results obtained showed that the optimum initial pH for Pb(II) removal was in the range 3-4, leading to removal yields of about 90-100% for initial metal concentrations of 10-100 mg/L. Cork biomass without treatment provided a higher removal yield (93%) than the biomass submitted to previous extraction with deionised water (80%), ethyl acetate (83%) and ethanol (88 %). The Langmuir model showed a very good correlation with experimental results (r2=0.995) and the Qmax was determined as being 5.3 mg Pb(II)/g cork. The optimisation of continuous bioremoval of Pb(II) (10 mg/L) from 25 L of influent, regarding metal uptake yield and volume of effluent containing a Pb(II) concentration 1 mg/L (MAV), was carried out by the factorial design methodology, leading to the establishment of the best operating conditions. In these conditions, two fixed bed-reactors (operational liquid volume of each reactor containing 20g of biosorbent=138 mL) running in sequential mode (feed flow rate - 590 mL/h) were more efficient (effluent volume with [Pb(II)] 1 mg/L=10 L) than one reactor alone (effluent volume with [Pb(II)] 1 mg/L=5 L). Finally, the chemical characterization in terms of CQO, TOC and phenolic compounds of the effluent before discharge showed that all values were lower than the ones allowed by environmental legislation

Socio-environmental Vulnerability Index: an Application to Rio de Janeiro-Brazil

Objectives: The concept of vulnerability has been used more frequently in several studies, in an attempt to better understand the specificities and needs of different population groups, both in environmental and socio-economical terms. The aim of this study is to identify, characterize and analyze populations in situations of socio-environmental vulnerability in the city of Rio de Janeiro, based on social, economic, environmental and public health indicators organized into a summary index – the Socio-Environmental Vulnerability Index. Methods: The methodology integrated 15 indicators in a Multi-Criteria Decision Analysis into a Geographic Information System. Results: According to our results, socio-environmental vulnerability in Rio de Janeiro is aggravated by at-risk situations and environmental degradation. These aspects are jeopardized by the population density in slum areas, where the most disadvantaged groups live in a process of environmental and urban exclusion. Conclusion: The study concludes about the importance of these tools in guiding resource allocation and their contribution to formulating and implementing more effective public policies.info:eu-repo/semantics/publishedVersio

Mean length utterance (MLU) as a measure of language development of children with Down syndrome

OBJETIVO: Caracterizar a extensão média de enunciados em morfemas (EME-m) e palavras (EME-p) produzida por crianças com síndrome de Down (SD) e verificar a eficácia da utilização da EME-p como medida do desenvolvimento linguístico geral de crianças com SD. MÉTODOS: Participaram 15 crianças com SD, com idades entre cinco e 12 anos, que foram submetidas à situação de interação livre. As crianças foram divididas em três grupos, com base na idade cronológica e mental, a partir da aplicação do Primary Test of Nonverbal Intelligence. Os 100 primeiros enunciados foram analisados quanto a: número de morfemas gramaticais para artigos, substantivos e verbos (MG-1) e pronomes, preposições e conjunções (MG-2); extensão média dos enunciados considerando-se morfemas (EME-m) e palavras (EME-p). RESULTADOS: A comparação intergrupos mostrou que quanto maior a idade, mais altas foram as médias obtidas, havendo diferença para todas as variáveis, com exceção de MG-2. Os mesmos resultados foram obtidos na comparação intragrupo para todas as variáveis. Houve forte correlação entre EME-m e EME-p. CONCLUSÃO: A EME-p pode ser utilizada como medida de identificação de desenvolvimento linguístico geral. No entanto, ressalta-se que a utilização de todas as variáveis relacionadas à extensão média de enunciados fornece maior eficiência na identificação do desenvolvimento linguístico e na análise de suas alterações.PURPOSE: To characterize the mean length utterance in morphemes (MLU-m) and words (MLU-w) produced by children with Down syndrome (DS), and to verify the effectiveness of using EME-w as a measure of general language development of children with DS. METHODS: Participants were 15 children with ages between 5 and 12 years, who were submitted to a free interaction situation. They were divided into three groups, according to chronological and mental age, as established by the results of the Primary Test of Nonverbal Intelligence. The first 100 utterances were analyzed considering: number of grammatical morphemes (GM) for articles, nouns and verbs (GM-1), and pronouns, prepositions and conjunctions (GM-2); mean length utterance for morphemes (MLU-m) and words (MLU-w). RESULTS: The between-groups comparison showed that the MLU averages were higher for older groups, and differences were found for all variables, except for GM-2. The same results were obtained in the within-group comparison, for all variables. There was a strong correlation between MLU-m and MLU-w. CONCLUSION: MLU-w can be used as an identification measure of general linguistic development. However, it is emphasized that the use of all MLU variables provides more efficacy in the characterization of linguistic development and the analysis of language impairments.CNPqFAPES

Thermalism in Portugal: corporate response to the COVID-19 pandemic – Strategy, Safety, Human Resources and marketing approach

Framework: Health tourism is currently one of the fastest growing forms of tourism. In Portugal, the “Tourism Strategy 2027” highlighted thermal activity as a means of economic development in the country's regions. On March 11, 2020, WHO declared a covid-19 pandemic. In Portugal, all thermal establishments took the initiative to suspend activity. After the lockdown period the units had to adapt to restart following the guidelines of the health authorities. Goals This study aims to emphasize the spa health tourism sector in Portugal in the context of the Covid-19 pandemic, analyze consumer behavior, and suggest future research on the topic. Paper organization: We present qualitative research, through content analysis using WebQDA software and a bibliometric analysis of co-occurrence of keywords in the thermal field, using the VOSviewer software. The analysis was conducted considering public statements from representatives of 21 units in mainland Portugal, published in the media, as of March 2020. Results: The analyses point to a high appreciated value by the customers to the item safety and to the aesthetic and medicinal treatments. There were no differences in behavior between public and private entities. All regions in mainland Portugal behaved the same way in terms of compliance with the health organization's guidelines, seeking to give the customer more safety and confidence. The training and actions of the human resources were essential to adapt the spas to guarantee strict safety and hygiene rules, as well as the respect for physical distance. In terms of marketing and innovation, the biggest references from the clients are at the product level. Final considerations: The current context of the Covid-19 pandemic favors the use of spas for their curative aspect related to lung problems, post-disease. There are several opportunities for hydrotherapy and research associated with the sector. It is important to draw new lines connected to its potential role in accelerating healing and prevention of coronavirusinfo:eu-repo/semantics/publishedVersio
