Biotechnology in aquaculture: polyploidy versus transgenic technology

Dissertação mest., Engenharia Biológica, Universidade do Algarve, 2009Triploidy is the condition in which somatic cells contain three sets of chromosomes which might be a consequence of environmental changes or hybrid stabilization, though in the present work the ploidy induction was done by hyperbare pressure. Diploid and triploid Rainbow trout, Onchorynchus mykiss (Walbaum, 1792) were the species characterized in this thesis. Besides ploidy a modification in the mineral availability of phosphorous, was applied influencing the whole body mineral homeostasis in diploid and triploid trout. The skeletogenesis in triploids animal is different from the diploid, having a general delay, the mineral deficient diet has also an impact on the ossification retreating. It allowed studying the development through triploids, which at the end of this trial they grew less than diploids. Vertebra area is also affected varying acconding to their regions, total number of vertebra differs, and in average triploids have less one vertebra than diploid groups. And there are also histological differences at a muscle level, having triploid Diet A less myotomes in average. Animals present a high capacity in recovering, once they start eating a normal diet in mineral composition, the restore their mineral content in bone structures in some situation an over calcification is observe (Diploid A). In a molecular level, there were any molecular differences observed only a high variability at the OSN levels

Biblioteca escolar e formação do leitor: integração possível?

Esta investigação analisa a atuação de bibliotecas escolares na promoção do acervo de obras do Programa Nacional Biblioteca da Escola (PNBE). Com o objetivo de acompanhar os processos que ocorrem a partir do recebimento de obras do referido acervo PNBE, foram realizadas cinco entrevistas semiestruturadas com professoras que atuam nas bibliotecas da Rede Pública Municipal de Ensino de Caxias do Sul, RS. Seguindo princípios de base qualitativa, o estudo pauta-se em conhecimentos prático-teóricos da área de Biblioteconomia, Letras e Educação e tem como base o cenário brasileiro e o português. O artigo aponta para o desconhecimento do profissional da biblioteca sobre a utilização do acervo e de guias do PNBE e que a biblioteca escolar tende a ser um setor passivo, apoiando e não promovendo ações

capacitação de segurança operacional para gestores de aeroportos classe I

O tema infraestrutura aeroportuária é abordado sob diversos aspectos no âmbito do setor de transporte aéreo. Todos os esforços são voltados para adequação e ampliação da infraestrutura existente nos aeroportos de pequeno porte para atender satisfatoriamente as empresas aéreas e passageiros. No entanto, a mesma ênfase não é dada à capacitação dos gestores aeroportuários, responsáveis pela manutenção da condição segura de operação dessa infraestrutura. Sob a ótica da segurança operacional, o presente estudo objetivou, por meio de consulta à regulação vigente e conceitos de gestão, abordar a relação entre capacitação de gestores aeroportuários com foco nos requisitos de segurança operacional e a operação de voos de empresas de transporte aéreo regular e não regular nesses aeroportos.The airport infrastructure theme is addressed in several aspects within the scope of the air transport sector. All efforts are aimed at adapting and expanding the existing infrastructure at small airports to satisfactorily serve airlines and passengers. However, the same emphasis is not given to the capacitation of airport managers, who are responsible for maintaining the safe operating condition of this infrastructure. From the perspective of operational safety, the present study aimed, through consultation of the current regulation and management concepts, to address the relationship between capacitation of airport managers with focus on operational safety requirements and the flight operation of regular and non-regular air transport companies at these airport

Property tax as urban planning instrument in large cities: the Brazilian experience

There is an ongoing process of increasing urbanization of the world population with socio-spatial polarization in large cities. Such population density increases the competition for urban land, arousing crescent ground rent generation from the central areas, where there is greater availability of urban infrastructure. The outcome of this process has been an extensive growth of these cities, generating costs for the low-income population, forced to take longer trips to get to work centers. It is also represents a cost increment for public administration, responsible for the expansion of urban infrastructure networks. One among the various instruments to face these costs is the urban real estate taxation, which can also fulfill an extra fiscal function, when used to regulate land use. In this article, we aim to analyze urban policy in Brazil regarding the use of the property taxation instrument, arguing its effectiveness in controlling land use. This was an important innovation introduced by the 1988 Federal Constitution and it is associated with private property defense as long as it fulfills its social function. Under these conditions, the main tax levied on real estate assets in Brazil, the Urban Building and Land Tax (IPTU), would be used as an urban policy instrument by foreseeing the possibility of using different rates according to the land's condition (built or not), its destination (residential or commercial), and also predicting progressive rates for properties that do not comply with the social function. Our study takes as reference municipalities with population over 200,000 inhabitants

A Cause to Action: Learning to Develop a Culturally Responsive/Relevant Approach to 21st Century Water Safety Messaging through Collaborative Partnerships

Globally, and in the United States, drowning is considered a “neglected public health threat” (WHO, 2014b). Reports have shown that there are groups of people in certain communities who are at greater risk. African Americans, as a group, have a drowning death rate 9% higher than that of the overall population, with the greatest disparity being among African American youth (Gilchrist & Parker, 2014). While many national programs and organizations present water safety awareness and drowning prevention efforts within communities, very few offer multi-sectorial collaborative efforts (WHO, 2017a) among culturally and linguistically diverse (CLD) aquatic stakeholders designed to empower, promote, and support water safety awareness in communities. Inspired by evidence-based research, derived from a national water safety and drowning prevention campaign, the purpose of this article is to answer a call to action by the World Health Organization (2017a) to approach water safety education through a social justice lens to inform programming and collaborative partnerships

Resiliência do cuidador domiciliar da pessoa idosa durante a pandemia da COVID-19

Objective: This study aims to identify the resilience level in formal and informal in-home caregivers of older adults in Ibagué during the COVID-19 pandemic. Methods: Quantitative, descriptive, cross-sectional study with a convenience sample of 49 formal and informal in-home caregivers of older adults. We administered the Brief Resilient Coping Scale (BRCS), an instrument consisting of four items, to these caregivers. The questionnaire was self-completed and, in some cases, answered by telephone. The data were collected in April 2020. Results: 35 women and 14 men participated in this study. The formal (69.4 %) and informal caregivers, mostly family (30.6 %), were between 18 and 30 years old (65.30 %). Their resilience levels were high (16.3 %), moderate (61.3 %), and low (22.4 %). There was a significant association between caregiver type and resilience level (p ≤ 0.05). Other studied covariates did not show a significant association. Conclusions: Due to stressful situations caused by care during social isolation and the risk of death of the elderly by COVID-19, strategies to improve resilience related to emotional, cognitive, and sociocultural interventions in the caregiver should be considered.Objetivo: este estudio tiene como objetivo identificar el nivel de resiliencia en cuidadores formales e informales de adultos mayores en el hogar en Ibagué durante la pandemia del COVID-19. Métodos: estudio cuantitativo, descriptivo y transversal con una muestra de conveniencia de 49 cuidadores formales e informales de adultos mayores en el hogar. Aplicamos la Escala Breve de Afrontamiento Resiliente (BRCS), un instrumento que consta de cuatro puntos, para estos cuidadores. Ellos mismos completaron el cuestionario y, en algunos casos, lo respondieron por teléfono. Los datos se recopilaron en abril de 2020. Resultados: 35 mujeres y catorce hombres participaron en este estudio. Los cuidadores formales (69,4 %) y los cuidadores informales, en su mayoría familiares (30,6 %), tenían entre 18 y 30 años (65,30 %). Sus niveles de resiliencia fueron altos (16,3 %), moderados (61,3 %) y bajos (22,4 %). Hubo una asociación significativa entre el tipo de cuidador y el nivel de resiliencia (p≤ 0,05). Otras covariables estudiadas no mostraron una asociación significativa. Conclusiones: debido a las situaciones de estrés causadas por la atención durante el aislamiento social y el riesgo de muerte de los adultos mayores por COVID-19, se deben considerar estrategias para mejorar la resiliencia mediante intervenciones emocionales, cognitivas y socioculturales en el cuidador.Objetivo: o objetivo deste estudo é identificar o nível de resiliência de cuidadores domiciliares formais e informais de idosos maiores no lar em Ibagué, Colômbia, durante a pandemia ocasionada pela COVID-19.
