Incineração de Resíduos Sólidos Urbanos: qual a melhor opção de aproveitamento energético?
Embora com bastante atraso relativamente aos seus parceiros, Portugal procura alcançar os padrões europeus no que concerne à gestão eficaz de Resíduos Sólidos Urbanos.
Neste domínio, a legislação portuguesa observa o previsto nas Directivas comunitárias mas os respectivos mecanismos de aplicação não são suficientemente fortes para que os resultados possam ser considerados satisfatórios.
A implementação de novas soluções no domínio do tratamento dos Resíduos Sólidos Urbanos, além de aparecer muito tardiamente, demora longos períodos de tempo a ser concretizada (contestação das populações, contestação dos consórcios não seleccionados, o desencadear de complicados e morosos procedimentos administrativos nas mais variadas instâncias!...).
Em Portugal está prevista a instalação de duas unidades de incineração de Resíduos Sólidos Urbanos com recuperação de energia. Estas produzirão exclusivamente electricidade. Assim sendo, o aproveitamento do potencial energético dos resíduos é muito reduzido. Se a opção fosse a produção simultânea de calor e electricidade, por cogeração (situação mais frequente neste tipo de unidades a nível mundial), o potencial energético das referidas instalações aumentaria significativamente. Tal facto seria bastante importante num País em que as necessidades energéticas dependem em 90% na importação em particular de petróleo (actualmente ainda nos 70%). O potencial energético dos Resíduos Sólidos Urbanos, bem como o impacto de programas de reciclagem a nível energético, são abordados
Regular physical exercise training assists in preventing type 2 diabetes development: focus on its antioxidant and anti-inflammatory properties
Diabetes mellitus has emerged as one of the main alarms to human health in the 21st century. Pronounced changes in the human environment, behavior and lifestyle have accompanied globalization, which resulted in escalating rates of both obesity and diabetes, already described as diabesity. This pandemic causes deterioration of life quality with high socio-economic costs, particularly due to premature morbidity and mortality. To avoid late complications of type 2 diabetes and related costs, primary prevention and early treatment are therefore necessary. In this context, effective non-pharmacological measures, such as regular physical activity, are imperative to avoid complications, as well as polymedication, which is associated with serious side-effects and drug-to-drug interactions
Access to information, concerns, myths and truths on food safety during COVID-19: an overview of Portuguese population
Purpose: The COVID-19 pandemic raised questions and concerns about the possibility of transmission of SARS-CoV-2 via foods. While cases of COVID were rapidly rising, information related to the virus and ways of prevention was also increasing, with much of this information being provided by the media and the general population. In this context, this study had two main objectives: 1) To understand the doubts and concerns of the Portuguese population related to food safety during the first wave of COVID-19 and how they clarified these issues and 2) to analyze the population's opinion on myths and truths related to the transmission of the infection. Methods & Materials: A survey including questions about a) concerns and information on food safety during the first wave of COVID-19 pandemic; b) myths and truths about COVID-1 and c) respondents’ profile. The survey was released online between June and October of 2020.Results: The main doubt of the respondents was related to the manipulation of food (40,7%) followed by the possibility of transmission of COVID-19 through food (12,6%) and which foods should be avoided due to the pandemic (12,6%). 33,3% of the participants stated that television was the main mean of information accessed to clarify these doubts, followed by a Guideline launched by the Directorate-General of Health (31,8%). However, 50,3% said that they had only found answers to some of their questions. 50% of the respondents with higher level of education and 30% of the respondents with lower level of education had doubts about the possibility of the transmission of COVID-19 through food. Also, most of the survey participants disagreed with the affirmations regarding popular ways of disinfecting food to prevent infection. Conclusion: COVID-19 pandemic raised several doubts, however when related to food safety, the main doubt was about the manipulation of food due to the concern of SARS-CoV-2 transmission. Most respondents do not believe myths about COVID-19 and food safety, but this was dependent on the level of education.info:eu-repo/semantics/publishedVersio

A study about web accessibility in Portuguese museums: How to overcome the main difficulties
Museums and their websites are an important component in the promotion of accessible tourism. However, some problems related to web accessibility may raise great barriers to the practice of tourism by people with disabilities. This study evaluates the level of website accessibility of museums located in Portugal, as it illustrates the importance of information being presented in an accessible way. A sample of 575 websites was analysed based on Web Content Accessibility Guidelines (WCAG) 2.0, using an automatic web diagnostic tool (AccessMonitor). This analysis was performed considering the A, AA, and AAA conformance levels of WCAG. Currently the state of web accessibility levels is medium, and there are still constraints that make information gathering difficult for visitors with disabilities. After the barriers are identified, proposals to design more accessible websites are presented. These proposals contribute to making museums’ online information accessible to all people, independently of their needs and functional limitations
Access to information, and concerns, myths and truths about food safety during the COVID-19 pandemic: an overview of the Portuguese population
The COVID-19 pandemic raised questions and concerns about the possibility of the virus being transmitted through food, as the virus was found in sewage, shrimps and packages of frozen food. During the first wave of COVID-19, concerns about the transmission of SARS-CoV-2 through food arose. As the number of cases began to increase rapidly, so did the availability of information regarding the virus and ways to prevent infection. A significant portion of this information was disseminated by the media and the general public. Identifying and understanding the main doubts and concerns about food hygiene and safety raised by the Portuguese population during the first wave of COVID-19 is important in order to understand whether these issues have influenced their practices and what lessons can be learnt for food safety and hygiene education. The aims of this work were (1) to understand the doubts and concerns of the Portuguese population regarding food safety and hygiene during the first wave of COVID-19, and how these issues were clarified, (2) to analyze the population’s opinion on food/hygiene myths and truths related to the transmission and prevention of the infection, and (3) to understand how the first wave of COVID-19 may have influenced the population’s practices linked to food handling and consumption. The main doubts of the respondents were related to food handling (41.6%) and the possibility of transmission of COVID-19 through food (17%). Television was the main source of information used to clarify these doubts (32.9%), followed by a guideline issued by the Directorate-General of Health (30.7%). However, most respondents (50.9%) said that they had only found answers to some of their questions. Most respondents reported washing and disinfecting hands before (85% and 63.4%, respectively) and after (73.8% and 57.3%, respectively) the handling and organization of food purchases. Most respondents did not believe the myths about COVID-19 and food safety, but this depended on their level of education. Some practices may have changed as a result of the pandemic, particularly with regard to washing and disinfecting hands and food, as well as kitchen hygiene.info:eu-repo/semantics/publishedVersio
Nutritional and Health Profile of Goat Products: Focus on Health Benefits of Goat Milk
Goat (Capra hircus) is one of the main sources of milk and meat products for human consumption. Goat milk differs from cow and human milk in both composition and nutritional properties. Goat milk and other goat-derived products contain several bioactive compounds that might be useful in patients suffering from a variety of chronic diseases. Several peptides, fats, and oligosaccharides present in goat’s milk can be potentially useful in cardiovascular disease, metabolic disorders, neurological degeneration, or in promoting intestinal health. They have also shown chemopreventive properties in cancer. In addition, the oligosaccharides present in goat’s milk have immunomodulatory properties, prevent adhesion of pathogenic bacteria, and have prebiotic, probifidogenic effects. Due to its potential health benefits, goat milk is particularly recommended for infants, older adults, and convalescing people. This chapter gives an overview of the biological activities of goat products and the effects of peptides, fats, and oligosaccharides present in goat milk on pathogenic bacteria, as well as their ability to regulate immunological, gastrointestinal, hormonal, and neurological responses in humans
