L’uso della cartografia digitale come base per la realizzazione di un SIT dedicato alle reti sentieristiche in Campania: esempi ed applicazioni.

The development of the hiking paths network in the Campania Region, its marking and maintenance in the field, as well as the relative cartographic restitution on up-to-date maps are nowadays important objectives, since the naturalistic tourism in mountainous environment has recently become more intense, and consequently it is necessary a correct and secure fruition of the hiking paths in the various Campanian mountains groups. Therefore, it is important implementing a Geographical Information System (GIS) dedicated to the Campanian hiking paths network with the aim of process, storing and managing all the parameters and characteristics of the local paths, also during time. In this study some routes of naturalistic and environmental particular value have been selected, which are located in the Lattari Mountains Group, the Vesuvius National Park and the Capri Island. GPS field survey measurements have been carried out along these routes and stored using the national official digital cartography. The field measurements have been taken during yearly scheduled excursions of the Neapolitan section of the Italian Alpine Club. The acquired data have been plotted on the relative maps, stored with the relative attributes tables and visualized through Google Earth interactively.The obtained results represent a feasibility study for a GIS of the hiking paths network of the Campania Region, with evident advantages and possible future developments not only for the trekkers but also for environment protection goals

Approccio metodologico per l’ individuazione di siti potenzialmente inquinati attraverso l’integrazione di dati multiparametrici, in ambiente GIS: un esempio di applicazione al Comune di Marigliano (Napoli)

In the most recent year, the environmental monitoring is became important for managing of territory and mitigation of the geo-environmental risks. The integration of the current geo-technologies and geomorphologic, geological, geochemical and geophysical parameters is fundamental for excellent results. In this paper we describe a methodology of study to identify environmental anomalies (illegal buried waste) of the Marigliano town, in province of Naples, brownfield of national interest for the reclamation. Particularly we have been described the use of satellite imagines in several years that has been the goal of this research. Brownfields not known potential contaminated have been identified and managing in GIS system to give a base for realization of a control support system

Chloroform formation by chlorination of aqueous algae suspensions: online monitoring via membrane introduction mass spectrometry

Membrane introduction mass spectrometry (MIMS) was used to perform on-line monitoring of the chloroform formation via the chlorination of aqueous suspensions of several green and blue-green Brazilian algae (Microcystis panniformis, Selenastrum sp., Scenedesmus sp., Monoraphidium sp. (strain 354), Monoraphidium sp. (strain 960), and Staurastrum sp.). The influence of major parameters, such as temperature, pH, initial concentration of sodium hypochloride, filtration, and reaction time, on chloroform formation was evaluated. It was verified that the chloroform formation is strongly dependent on the alga type and is favored by high temperatures, pH, sodium hypochloride initial concentration and reaction time. Finally, filtered algae samples produce smaller amounts of chloroform in comparison to the rough suspension.A técnica MIMS (membrane introduction mass spectrometry) foi utilizada para monitorar a formação de clorofórmio durante a cloração de suspensões aquosas de várias espécies brasileiras de algas verdes e azuis (Microcystis panniformis, Selenastrum sp., Scenedesmus sp., Monoraphidium sp. (strain 354), Monoraphidium sp. (strain 960), and Staurastrum sp.). Foram avaliadas as influências de parâmetros como temperatura, pH, concentração inicial de hipoclorito de sódio, filtração e tempo de reação. Foi constatado que o teor de clorofórmio é fortemente dependente da espécie de alga e também é favorecido com o aumento da temperatura, pH, dosagem de cloro inicial e do tempo de reação. Amostras de suspensões de algas submetidas a filtração produziram menores quantidades de clorofórmio em comparação com as amostras brutas.950955Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq

Anthocyanins identification and quantification in new acai access.

Compostos bioativos e atividade antioxidante de genótipos de açaí (Euterpe oleracea).

O estresse oxidativo gerado pelo excesso de espécies reativas no organismo ou por uma produção inadequada de antioxidantes está associado com o desenvolvimento de doenças crônicas não transmissíveis (DCNTs) e esta condição pode ser minimizada por antioxidantes exógenos da dieta. Neste contexto, o açaí é uma opção para obter antioxidantes (polifenóis e carotenoides) e seu consumo está associado com efeitos benéficos contra as DCNTs. O objetivo deste estudo foi avaliar seis genótipos de açaí do programa de melhoramento genético desenvolvido pela Embrapa-Amazônia Oriental em relação ao conteúdo de compostos bioativos e atividade antioxidante pelo método ABTS. Os resultados mostram um aumento na atividade antioxidante dos frutos melhorados associado ao incremento no teor de antocianinas e carotenóides. Tal resultado indica genótipos promissores à continuidade do programa de melhoramento do açaí, resultando em frutos com uma maior quantidade de antioxidantes para o consumidor

A seismic array on Mt. Vesuvius

In November 1997 a seismic antenna (array) of short period seismometers was installed on the south-western flank of Mt. Vesuvius; aim of the experiment was to test the use of non-conventional devices for the seismic monitoring of this volcano. In 7 months local seismicity, regional earthquakes and samples of seismic noise were recorded by the array and organised in a data base. Local earthquakes and seismic noise have been analysed with array techniques to investigate the spectral, kinematic and polarization properties of the wavefield. Preliminary results show that the backazimuth of local earthquakes is oriented in the direction of the crater area. For some events, the source location has been constrained using a simplified back propagation in a 2-D velocity structure. The noise wavefield is characterized by the predominance of a sustained low frequency component (< 1Hz) whose source is located S-SE of the array. This low frequency signal has been interpreted as associated to the sea-loading in the gulf of Naples.Istituto Nazionale di Geofisica e Vulcanologia, Osservatorio VesuvianoPublished1.4.
