However, technological progress and development of regional transport system observed afterwards led to functional disuse and gradual decline of these boats. In the 1980s, social and institutional acknowledgement of their cultural and patrimonial value provided for the launch of the process of recuperation and preservation of these traditional boats. However, nowadays the preservation of these patrimonial elements faces a complex of new challenges which in some cases threat their sustainability. Supported by the analysis of the valorisation process of the Tagus Estuary traditional boats and based on experience of various local st...

Um processo despoletado pela atractividade exercida por estes espaços para a fixação humana e, por esta via, para o desenvolvimento de uma multiplicidade de actividades. No caso das frentes ribeirinhas do concelho da Moita (Estuário do Tejo), a ocupação com actividades ligadas a funções litorais, actividades agrícolas e actividades industriais moldou este território de interface terra-água. No período pós-industrial, as estratégias intervenção para estas frentes ribeirinhas reflectem esta estrutura de ocupação. Neste âmbito, a comunicação centra-se no teste da hipótese segundo a qual são predominantes as orientações conducentes (i) à requalificação dos espaços urbanos confinantes com o plano de água, e (ii) à reabilitação e revalorização ambiental das áreas ocupadas essencialmente por estruturas de...

Este trabalho foi desenvolvido com o objetivo de avaliar os efeitos da irrigação sobre a produção e o desenvolvimento do cafeeiro irrigado por gotejamento na região Oeste da Bahia. Para isso foi implantado um experimento na fazenda Café do Rio Branco, localizada em Barreiras – BA, em cafeeiros adultos, aproximadamente 3,5 anos de idade, da variedade Catuaí Vermelho IAC 144. O experimento foi montado no delineamento em blocos casualizados, composto de 5 tratamentos, correspondentes à 75, 85, 100, 125 e 150% da lâmina de irrigação calculada pelo software Irriplus. Observou-se, ao final de quatro safras, efeito significativo da lâmina de irrigação na produtividade do cafeeiro. A produtividade máxima estimada (60 sc ha-1) foi obtida com a lâmina correspondente a 122% da lâmina de irrigação. Nã...

Um processo cujo enfoque estratégico torna possível a sua sistematização em várias abordagens valorativas, como são por exemplo os casos da conservação e reconversão funcional do património construído, da conservação e salvaguarda do património cultural e da valorização do património como elemento simbólico de referência. Neste contexto, muitas intervenções em frentes de água têm contemplado a valorização do património marítimo flutuante através da presença de embarcações tradicionais/navios históricos no plano de água adjacente. Com base nalguns casos de estudo, pretende-se interpretar e discutir a abordagem subjacente a esta opção, que possibilita não apenas a conservação do património marítimo, mas permitindo também a sua apropriação enquanto eleme...

Natural disasters, business crises, pandemics, workplace crime, or any other incident that disrupts business operations are examples of emergencies. Maturity models provide companies with a way to assess their relative implementation for a management framework. This paper provides a Process Assessment Model for Business Continuity based on a Systematic Literature Review. The selected articles from the literature provide information about the state-of-the-art in this research field, an understanding of the numerous research activities that have been undertaken in recent years, and a forecast of potential developments.

Dentro deste contexto, conduziu-se experimento com a finalidade de avaliar o efeito da aplicação de fertilizantes organominerais associados ao esterco de galinha sobre a nutrição mineral, o crescimento e a produtividade do cafeeiro irrigado e cultivado em condições de cerrado. O experimento utilizou o delineamento experimental em blocos ao acaso com quatro repetições e quatro tratamentos. Foram avaliados os aspectos biométricos e a produtividade. Concluiu-se que o uso de fertilizantes organominerais é viável para a cultura do café, na medida em que garante às propriedades favoráveis da matéria orgânica, a fim de evitar a desuniformidade das fontes nutricionais dos adubos exclusivamente orgânicos. O uso do fertilizante organomineral isolado ou em associação tem o mesmo comportamento em termos de produtividade de café com es...

The interdependence between CIs makes them vulnerable to large-scale cascading disasters that can significantly impact society. Cascading effects in CIs are thus a worthy area of study and research, with considerable interests in terms of resilience and risk management. In this paper, a domain ontology of cascading effects was developed using the systematic approach to ontology construction (SaBiO) methodology, which provides guidelines for developing domain ontologies. A systematic literature review (SLR) was used to obtain information, an essential part of the first phase of SaBiO. This research identified the main concepts in the domain of cascading effects. Additionally, the relations between the concepts were also identified, which were formalised in the proposed ontology. Besides the proposed ontology, a small analysis of the domain of the cascading effects was also performed. The ontology proposed was also validated using real cases of cascading effects events from an organisation.

However, in recent years, with climate change, years with water deficits greater than 150 mm have been observed, affecting the vegetative and productive development of the crop and also the replenishment of surface and underground springs. One practice that increases soil water retention capacity is organic fertilization. This work evaluated different combinations of irrigation and organic fertilization on the yield and quality of coffee produced in the Minas Gerais cerrado region. The treatments were: T1: total irrigation; T2: no irrigation; T3: total irrigation + organic fertilization (chicken manure, 10 ton ha-1); T4: no irrigation + organic fertilization (chicken manure, 10 ton ha-1); T5: 50% irrigation + organic fertilization (chicken manure, 10 ton ha-1). After 7 harvests, it was concluded that the treatment that combined organic fertilization with application of half of the necessary irrigation presented th...

Vaccination is the best preventive measure against YF. Attenuated YF 17DD vaccine has been produced since 1937 by Bio-Manguinhos/Fiocruz, being the most effective and safest vaccine ever developed. However, some adverse events are associated with vaccination, such as viscerotropic disease, anaphylactic reactions and neurological disease. Between July 2017 and June 2018, a severe YF outbreak occurred in southeastern Brazil since 1947 resulting in 1,376 confirmed cases in humans with 483 deaths, and 864 confirmed epizooties in NHP. There is a strong demand for the development of a new vaccine for YF, as effective as the current one and safer, that is unable to cause viral disease in immunized population. Moreover, the absence of a vaccine available for NHP strengthens the need for studies to develop a vaccine for this purpose. Objective: In the present study, the immunogenicity of an inactivated 17DD vaccine in goldenheaded lion tamarin (Leontopithecus chrysomelas) was evaluated by the determination of the neutralizing antibody titers (PRNT 50). Methodology: The YF vaccine was inactivated with ß-propiolactone and adsorbed to different adjuvants. NHPs were immunized by intramuscular route with three doses of 17DD inactivated with aluminum hydroxide adjuvant or with two doses of 17DD inactivated with AddaVax™ adjuvant. NHP experiments were approved by the Animal Care and Use Committee (CEUA-UNIFESO 470/2018) and environmental license was authorized by the Brazilian Ministry of the Environment (ICMBio-SISBIO 60511-2/2018). Results: PRNT titers in serum samples from animals after the second and third immunization with 17DD inactivated with aluminum hydroxide adjuvant showed PRNT titers just above the detection limit of the assay (PRNT 50 titer > 5). On the other hand, immunization with 17DD inactivated with AddaVax™ adjuvant did not elicit robust antibody titer responses, even after the second dose. The overall seroconversion rate was also considerably higher in the group that received vaccine schedule with aluminum hydroxide when compared with the group that received vaccine with AddaVax™, where 83.3% and 0.0% individuals seroconverted, respectively. As expected, the control groups immunized with different doses of the live attenuated vaccine (groups 1, 2 and 3) showed 100%, 40% and 83.3% of seroconversion ninety days after inoculation, respectively. Conclusion: These data indicate the potential of this inactivated antigen for the development of a non-infectious YF vaccine. One year after the first immunization, all the groups will be challenged using attenuated 17DD vaccine to evaluate the protective efficacy of the inactivated vaccine.

Nas tres safras estudadas, todos os tratamentos realizados foram significativamente superiores em producao em relacao a testemunha, de 107 a 145%, indicando a importância dos nutrientes N, P, K e S no cultivo do cafe no cerrado. Entre os tratamentos, a maior dose de esterco (20,0 t ha-1) foi significativamente o tratamento mais produtivo; as demais doses nao apresentaram diferenca estatistica, embora tenham proporcionado aumentos de 9 a 19% na produtividade, em relacao ao tratamento exclusivamente mineral. No solo, observouse que, em funcao das do...

Financial knowledge and evolutionary algorithms are incorporated in the system to achieve a better performance when choosing the stocks to compose the portfolio. The main goal is to design a strategy which captures the most promising growing companies on the market. To achieve this goal, the system designed incorporate a fundamental approach and a market division by sectors/industries, using financial ratios and sector specific indicators. Several investing strategies were tested, and further validated using as measures the return, variance and extra risk. The simulations were conducted using data from the S&P 500 index for the periods January 2011 until December 2014. Real constraints are used to define an environment similar to the ones faced by real portfolio managers. The results demonstrated that combining evolutionary computation with financial ratios is a good solution ...

Não obstante esta dinâmica, prevalece o problema da regeneração dos brownfields do segundo ciclo de industrialização, cuja extensão, localização periférica e passivos ambientais associados, enformam um novo desafio com o qual se debatem vários territórios. Isto sem que tenha sido ainda possível encontrar um modelo de intervenção que permitisse a sua revitalização. As frentes de água deparam-se ainda com outro desafio emergente: a adaptação às alterações climáticas, em particular à subida do nível médio das águas do mar. Com efeito, partindo da problematização destes desafios, são apresentadas e discutidas as bases do "Programa de investigação sobre os novos desafios das frentes de água: regeneração urbana e adaptação às alterações climáticas. O caso do Estuário do Tejo", conferindo particular atenção aos seus objetivos e à abordagem metodológica que lhe subjaz.

A feature common to many of these interventions relates to the appropriative valorisation of heritage and cultural identity stemming from past uses as a resource for new activities, elements of differentiation and vectors of territorial identity. Based on the analysis of various projects, this article presents and discusses the following proposal of systematizing the way in which heritage and identity are appropriated and valued in these interventions: functional conservation and redevelopment of built heritage; conservation and safeguarding of cultural heritage; valorisation of heritage as an important symbolic element; promotion of heritage as a basis for new cultural industries; enhancement of cultural events; valorisation of heritage as a resource for tourism and leisure. Essay on the valorisati...

Nas tres safras estudadas, todos os tratamentos realizados foram significativamente superiores em producao em relacao a testemunha, de 107 a 145%, indicando a importância dos nutrientes N, P, K e S no cultivo do cafe no cerrado. Entre os tratamentos, a maior dose de esterco (20,0 t ha-1) foi significativamente o tratamento mais produtivo; as demais doses nao apresentaram diferenca estatistica, embora tenham proporcionado aumentos de 9 a 19% na produtividade, em relacao ao tratamento exclusivamente mineral. No solo, observouse que, em funcao das do...

Financial knowledge and evolutionary algorithms are incorporated in the system to achieve a better performance when choosing the stocks to compose the portfolio. The main goal is to design a strategy which captures the most promising growing companies on the market. To achieve this goal, the system designed incorporate a fundamental approach and a market division by sectors/industries, using financial ratios and sector specific indicators. Several investing strategies were tested, and further validated using as measures the return, variance and extra risk. The simulations were conducted using data from the S&P 500 index for the periods January 2011 until December 2014. Real constraints are used to define an environment similar to the ones faced by real portfolio managers. The results demonstrated that combining evolutionary computation with financial ratios is a good solution ...

Não obstante esta dinâmica, prevalece o problema da regeneração dos brownfields do segundo ciclo de industrialização, cuja extensão, localização periférica e passivos ambientais associados, enformam um novo desafio com o qual se debatem vários territórios. Isto sem que tenha sido ainda possível encontrar um modelo de intervenção que permitisse a sua revitalização. As frentes de água deparam-se ainda com outro desafio emergente: a adaptação às alterações climáticas, em particular à subida do nível médio das águas do mar. Com efeito, partindo da problematização destes desafios, são apresentadas e discutidas as bases do "Programa de investigação sobre os novos desafios das frentes de água: regeneração urbana e adaptação às alterações climáticas. O caso do Estuário do Tejo", conferindo particular atenção aos seus objetivos e à abordagem metodológica que lhe subjaz.

A feature common to many of these interventions relates to the appropriative valorisation of heritage and cultural identity stemming from past uses as a resource for new activities, elements of differentiation and vectors of territorial identity. Based on the analysis of various projects, this article presents and discusses the following proposal of systematizing the way in which heritage and identity are appropriated and valued in these interventions: functional conservation and redevelopment of built heritage; conservation and safeguarding of cultural heritage; valorisation of heritage as an important symbolic element; promotion of heritage as a basis for new cultural industries; enhancement of cultural events; valorisation of heritage as a resource for tourism and leisure. Essay on the valorisati...
