The policy problem addressed in this article is the perceived under-exploitation of the potential availability of water resources in the town of Troina (a municipality of eastern Sicily, Italy). In order to help the local town administration, which raised this issue, a trans-disciplinary research team was formed with the purpose of testing some explanatory hypotheses and to provide possible alt...

In this paper, we present the role of remote sensing technology in the context of the monitoring of surface water status within the European union (EU) water framework directive (WFD). Although the digital evaluation of remotely sensed data has been used to estimate surface water characteristics for over two decades, there are still few discussions available on the contribution of remote sensin...

Background: Monte Carlo and experimental relative dose determination in a water phantom, due to a high dose rate (HDR) 192Ir source is presented for real energy spectrum and monochromatic at 356 keV. Materials and Methods: The dose distribution has been calculated around the 192Ir located in the center of 30 cm ×30 cm ×30 cm water phantom using MCNP4C code by Monte Carlo method. Relati...

Beam quality correction, kQQ0(r), for solid-state detectors diamond, LiF, Li2B4O7, Al2O3, and plastic scintillator are calculated as a function of distance, r, along the transverse axis of the 60Co and 192Ir brachytherapy sources using the Monte Carlo- based EGSnrc code system. This study also includes calculation of detector-specific phantom scatter correction, kphan(r), for solid phantoms suc...

Bangladesh is a cholera endemic country with a population at high risk of cholera. Toxigenic and non-toxigenic Vibrio cholerae (V. cholerae) can cause cholera and cholera-like diarrheal illness and outbreaks. Drinking water is one of the primary routes of cholera transmission in Bangladesh. The aim of this study was to conduct a comparative assessment of the presence of V. cholerae between poin...

A magnetically enhanced radio-frequency (rf) plasma source operating on water vapor has an extensive list of potential applications. In this work, the use of a rf plasma source to dissociate water vapor for hydrogen production is investigated. This paper describes a rf plasma source operated on water vapor and characterizes its plasma properties using a Langmuir probe, a residual gas analyzer, ...

Separation of different domestic wastewater streams and targeted on-site treatment for resource recovery has been recognized as one of the most promising sanitation concepts to re-establish the balance in carbon, nutrient and water cycles. In this study a model was developed based on literature data to compare energy and water balance, nutrient recovery, chemical use, effluent quality and land ...

The value that domestic users attribute to reliability of water supply and to the quality of this water is a function of several determinants, such as the source of water, the socioeconomic characteristics of households (per capita income, level of education, etc.), and other variables. Users that have private tap water at home may value less improved availability or more reliable source than h...
