Microbiological evaluation is one of the most important parameters for analyzing the viability of an oyster farming system, which addresses public health and ecological concerns. Here, the microbiological quality of the oyster Crassostrea rhizophorae cultivated in a monitored environment and from natural beds in Bahia, northeastern Brazil, was determined. Bacterial diversity in oysters was meas...

This paper briefly summarizes some recent IBM work in the areas of distributed commit protocols, andrecoverable messaging and queuing. We discuss the original presumed nothing commit protocol of SNALU 6.2 and the current industry standard presumed abort (PA) protocol which we originally developedin IBM’s R* project. We also discuss generalized presumed abort (GPA) which resulted fro...

Abstract Perennial rivers in desert regions are relevant environments that tend to concentrate most ecosystem services and values, but not as studied much intermittent ephemeral rivers. This article reports on the main morphological ecological features of Silala River, a narrow permanent river arid region Antofagasta, north Chile. The study was motivated by dispute between Chile Bolivia concern...

An investigation method to evaluate microbiological air quality has been developed; it involved a compiling building inspections checklist and occupants questionnaires, choosing sites, sampling frequency and analysis procedures. This method has been applied in a representative building with HVAC system and open-space offices. Air samples and microclimate parameters were collected at the same ti...

The acceptability of the quality of hotwater supplied by harvested rainwater in the urban environment has been the subject of much debate in many developed countries as a result of attempts to maximise usage of harvested rainwater in order to improve city water-cycle management. Debate has centred around the issues of the microbiological quality of the heated rainwater, since many tank water sa...

this study focused on use of bacterial extracellular enzyme activities as biochemical parameters, along with the microbiological and physicochemical characteristics, in a comprehensive assessment of water quality of four lake ecosystems in the province of vojvodina (northern serbia): provala, ludas, zobnatica and palic. water samples were collected in june and october, 2008. for assessment of ...

Many specialists note that the food offered today - as a result of very complex technological processing - is devoid of many components that are important for the organism and the shortages have to be supplemented. The simplest for it is to consume diet supplements that provide the missing element in a concentrated form. In accordance with the applicable law, medicinal products include all subs...
