The analysis of geochemical markers is a known valid tool to explore the water sources and understand main factors affecting natural quality, which are issues interest in environmental science. This study reports application characterize recharge areas multi-layer urban aquifer Como city (northern Italy). area presents perfect case test markers: hydrogeological setting affected by layered karst...

The implementation of all the United Nations Sustainable Development Goals (SDGs) requires sustainable energy production and consumption; hence issue accountability is vital. There are several studies on activities supreme audit institutions (SAIs); however, research question - what role SAIs in still without an answer. Meanwhile, SAIs, as critical public auditors have to evaluate how do govern...

Understanding the water balance of large groundwater systems is fundamental for the sustainable management of the resource. The vertical leakage (i.e. discharge to upper aquifers or the unconfined water table) component of the Great Artesian Basin (GAB) is an example of a poorly constrained but large component of the water balance of Australia’s largest groundwater resource. Field estimates of ...

Wells screened across multiple aquifers can provide pathways for the movement of surprisingly large volumes of groundwater to confined aquifers used for public water supply (PWS). Using a simple numerical model, we examine the impact of several pumping scenarios on leakage from an unconfined aquifer to a confined aquifer and conclude that a single inactive multi-aquifer well can contribute near...

Dois materiais energéticos, ricos em nitrogênio, baseados em 1-amino-2-nitroguanidina foram sintetizados. O comportamento térmico, propriedades termo-dinâmicas, estruturas eletrônicas e propriedades de detonação foram investigados. As curvas de calorimetria exploratória diferencial (DSC) mostram que 1-amino-2-nitroguanidina 2,4,5-trinitroimidazol (sal 1) pode ser usado como lançador de explosiv...

A grammar compression algorithm, called GCIS, is introduced in this work. GCIS based on the induced suffix sorting algorithm SAIS, presented by Nong et al. 2009. The proposed solution builds factorization performed SAIS during sorting. context-free used to replace factors non-terminals. then recursively applied shorter sequence of resulting encoded exploiting some redundancies, such as common p...

Purpose The aim of this paper is to compare the audit and accountability arrangements Supreme Audit Institutions (SAIs) internationally. Design/methodology/approach Building on a theorisation regulatory space, extended by new spaces public audit, scope research 196 SAIs that are full members International Organization (INTOSAI). study based documentation review, workshops with steering panel, s...

Coastal aquifers involve varying conditions in time and space, owing to the occurrence of free and moving boundaries, such as the water table, seepage face and saltwater intrusion interface. A fast Updating Procedure (FUP) is developed for solving these interfaces in steady and transient conditions with the finite element method. Several test examples, which involve confined and phreatic ground...
