A universalização do abastecimento de água no Brasil ainda é um desafio que se busca suplantar, sobretudo em relação ao atendimento a populações rurais difusas, onde os sistemas convencionais não respondem às demandas das famílias de agricultores dispersas. Nesse contexto, as nascentes de água podem contribuir como solução alternativa para o abastecimento doméstico, por se encontrarem próximas ao consumo e sob o controle do usuário Isto é evidenciado no estudo das nascentes situadas no Assentamento Serra Grande, no município de Vitória de Santo Antão, Zona da Mata de Pernambuco. Foram identificadas, cadastradas e selecionadas nascentes perenes, para caracterização da qualidade e vazão das águas, objetivando avaliá-las para usos múltiplos, com prioridade ao abastecimento doméstico. Evidenciou-se que a vazão, mesmo em períodos de estiagem, possui potencial de atender às necessidades básicas dos agricultores, para beber, preparo de alimentos, banho, lavagem de utensílios e roupas e descarga em sanitários. Quanto à qualidade para uso doméstico, em geral a água atende aos limites sanitários, embora em alguns casos a presença de Escherichia coli exija recuperação da nascente e cloração cuidadosa da água. Pelos resultados, a produção de água em nascentes situadas em solos e clima predominantes na Zona da Mata do Nordeste brasileiro, permite atender às necessidades básicas de abastecimento doméstico de agricultores familiares isolados ou em pequenas vilas rurais, sendo uma alternativa aos sistemas convencionais de abastecimento, já identificada pelo governo federal em seus recentes planos de abastecimento de populações rurais difusas. Palavras-chave: recursos hídricos; gestão ambiental; desenvolvimento rural  The Springs as Supply Source of Rural Diffuse Population  ABSTRACTThe universalization of the water supply in Brazil is still a challenge that it seeks to be supplant, especially in relation to the service to rural diffuse population, where conventional systems do not respond to the demands of farming families dispersed. In this context, the water springs may contribute as a workaround for domestic supply, because they are close to consumption and under user control. This is evidenced in the study of springs located at Settlement Serra Grande, located in the city of Vitória de Santo Antão, Zona da Mata de Pernambuco. It has been identified, registered and selected perennial springs, to characterize the quality and water flow, aiming to evaluate them for multiple uses with priority to domestic supply. It was evident that the flow even during drought periods, has potential to meet the basic needs of farmers, for drinking, preparing meals, baths, wash utensils and clothes and flushing toilets. As for the quality for home use, generally water meets health limits although in some cases the presence of Escherichia coli, requires careful recovery of the source and chlorination of water. According to the results, the production of water in springs located in soils and climate prevailing in Zona da Mata of Brazilian northeastern, it allows to meet basic needs for domestic supply from family farmers in small villages or isolated rural villages, being an alternative to conventional supply, already identified by the federal government in their recent plans for the supply of rural diffuse population.  Keywords: water resources; environmental management; rural development

In this paper the tasks of managing the directory in coherence maintenance systems in multiprocessor systems with a large number of processors are solved. In microprocessor systems with a large number of processors (MSLP) the problem of maintaining the coherence of processor caches is significantly complicated. This is due to increased traffic on the memory buses and increased complexity of interprocessor communications. This problem is solved in various ways. In this paper, we propose the use of Bloom filters used to accelerate the determination of an element’s belonging to a certain array. In this article, such filters are used to establish the fact that the processor belongs to some subset of the processors and determine if the processor has a cache line in the set. In the paper, the processes of writing and reading information in the data shared between processors are discussed in detail, as well as the process of data replacement from private caches. The article also shows how the addresses of cache lines and processor numbers are removed from the Bloom filters. The system proposed in this paper allows significantly speeding up the implementation of operations to maintain cache coherence in the MSLP as compared to conventional systems. In terms of performance and additional hardware and software costs, the proposed system is not inferior to the most efficient of similar systems, but on some applications and significantly exceeds them.

The Covid-19 pandemic is an extremely difficult time for musicians, and some, out of necessity and perhaps curiosity and experimentation, have been exploring digital realisations of music, such as live streamed or pre-recorded concerts. Examples that I have experienced or have been a part of include the experimental music ensemble Bastard Assignment's Lockdown Jams involving Zoom experiments, the experimental Free Range Concert Series streamed on YouTube, the Montrose Composers’ Club Zoom collaborations, and The Ensemble Whose Name is Uhhhhmm … (formerly Lil’ Jürg Frey) who perform music in Animal Crossing using in-game sounds.
