An integrated low-cost road traffic and air pollution monitoring platform for next citizen observatories

Abstract An integrated monitoring platform was developed for real-time monitoring of air pollution and traffic flows in urban areas. The air quality monitoring unit, integrating the "Arduino" open-source technology with low-cost and high-resolution sensors, collects concentrations of CO, NO 2 and CO 2 . The traffic monitoring device, equipped with a camera sensor and a video analysis software, collects vehicles' counts, speed and size. Air pollution and traffic readings are archived on a spatial data infrastructure composed of a central GeoDatabase, a GIS engine, and a web interface. A platform's description and the results of its installation in Florence (Italy) are presented

Benefícios da atividade física para a promoção da saúde dos idosos com alzheimer: uma revisão de literatura

The incidence of Alzheimer's disease (AD), the most common form of dementia in the elderly, has increased as the world's population ages, with millions of people affected worldwide. To date, there is no effective treatment for AD, and significant efforts are directed towards developing new strategies, such as regular physical activity, to counteract the mechanisms that lead to neuronal damage. In this sense, this study aimed to identify the effects that physical activity provides for the treatment of elderly people with Alzheimer's. The methodology used here was a literary review through books and articles. Based on these observations, we present that regular physical activity can help in the prevention and treatment of AD, being practiced by the patient and caregivers; It is up to Physical Education professionals to deepen further studies on these bases, in addition to informing about the benefits of physical activity to aid in the treatment of this disease.A incidência da doença de Alzheimer (DA), forma mais comum de demência em idosos, tem aumentado à medida que a população mundial envelhece, com milhões de pessoas afetadas em todo o mundo. Até o momento não existe um tratamento eficaz para DA, e esforços significativos são direcionados no sentido de desenvolver novas estratégias, como atividade física regular, para neutralizar os mecanismos que levam a danos neuronais. Neste sentido, este estudo teve como objetivo identificar os efeitos que a atividade física proporciona para o tratamento de idosos com Alzheimer. A metodologia aqui empregada foi uma revisão literária através de livros e artigos. Com base nessas obervações, apresentamos que a atividade física regular pode auxiliar na prevenção e no tratamento da DA, sendo praticado pelo paciente e pelos cuidadores; cabendo aos profissionais de Educação Física, o aprofundamento cada vez maior em estudos destas bases, além de informar sobre os benefícios da atividade física para o auxilio do tratamento dessa doença

Assessing sample representativeness for inorganic chemical investigation of invertebrates by INAA

The quality of environmental studies depends on the utilization of adequate sampling protocol and analytical method for obtaining reliable results and minimizing analytical uncertainties. In order to demonstrate the applicability of INAA for determining chemical element composition of invertebrates, this work evaluated sample representativeness in terms of subsampling and sample size. Br, Co, Fe, K, Na, Sc and Zn could be determined in very small samples despite increasing of analytical uncertainties. Special attention should be directed to invertebrate species with small structures because of the high chemical variation observed among different sample sizes tested.Conselho Nacional de Pesquisa (CNPq
