La vulnerabilidad del patrimonio bibliográfico en los conventos y monasterios. El caso de la Provincia de Santiago

2023

El patrimonio bibliográfico adquirido a lo largo del tiempo por las órdenes religiosas, como es el fondo conservado en la Biblioteca provincial franciscana de Santiago, ha sido fruto de una actividad académica intensa que, en el momento actual, ante la escasez de vocaciones, corre un grave peligro por falta de recursos materiales y personales, lo que hace que las bibliotecas conventuales se encuentren abocadas al deterioro y posterior pérdida.

Assessing the Feasibility of Wastewater Finishing Treatment by Modified Sand Filters.

2014

The purpose of this study was to investigate the performance of the modified biosand filtration at lab scale. The traditional biosand filter arrangement was modified adding a 2nd stage to the traditional single one. Pre-clarified wastewater first flows down through different filtration material layers; then flows upward in the second stage through other three - and finer - filtration layers including small gravel at the bottom, fine sand and small gravel again. During the experiment timespan (90 days) daily results were collected, analysed and tabled at the laboratories of the Publicly Owned Wastewater Treatment Station – Palermo, operated by AMAP. The analysis included bacteriological para…

A hydrodynamic water quality model for propagation of pollutants in rivers.

2010

Numerical modelling can be a useful tool to assess a receiving water body's quality state. Indeed, the use of mathematical models in river water quality management has become a common practice to show the cause-effect relationship between emissions and water body quality and to design as well as assess the effectiveness of mitigation measures. In the present study, a hydrodynamic river water quality model is presented. The model consists of a quantity and a quality sub-model. The quantity sub-model is based on the Saint Venant equations. The solution of the Saint Venant equations is obtained by means of an explicit scheme based on space-time conservation. The method considers the unificatio…

Optimization of acetate production from citrus wastewater fermentation

2021

Abstract Citrus wastewater is a sugar-rich waste stream suitable for the recovery of energy of material from its treatment. In this study, fermentation of citrus wastewater was carried out to assess the optimal conditions to maximize the bioconversion of the organic substrate into acetate. Unbalanced nutrient (C: N: P 200:0.1:0.1) enabled the highest acetate production. The presence of the particulate organic fraction enabled to obtain a higher acetate concentration regardless the initial COD concentration. Initial pH values higher than 5 did not cause substantial differences on the maximum bioconversion of COD into acetate in Trial 3, whereas pH lower than 5 hindered the hydrolysis process…

Freshwater pearl mussels from northern Sweden serve as long-term, high-resolution stream water isotope recorders

2019

The stable isotope composition of lacustrine sediments is routinely used to infer Late Holocene changes in precipitation over Scandinavia and, ultimately, atmospheric circulation dynamics in the North Atlantic realm. However, such archives only provide a low temporal resolution (ca. 15 years), precluding the ability to identify changes on inter-annual and quasi-decadal timescales. Here, we present a new, high-resolution reconstruction using shells of freshwater pearl mussels, Margaritifera margaritifera, from three streams in northern Sweden. We present seasonally to annually resolved, calendar-aligned stable oxygen and carbon isotope data from 10 specimens, covering the time interval from …

Factors controlling plankton productivity, particulate matter stoichiometry, and export fluxin the coastal upwelling system off Peru

2020

Abstract. Eastern boundary upwelling systems (EBUS) are among the most productive marine ecosystems on Earth. The high productivity in surface waters is facilitated by upwelling of nutrient-rich deep waters, with high light availability enabling fast phytoplankton growth and nutrient utilization. However, there are numerous biotic and abiotic factors modifying productivity and biogeochemical processes. Determining these factors is important because EBUS are considered hotspots of climate change, and reliable predictions on their future functioning requires understanding of the mechanisms driving biogeochemical cycles therein. In this study, we used in situ mesocosms to obtain mechanistic un…

Batch Test Evaluation of Four Organic Substrates Suitable for Biological Groundwater Denitrification

2014

Nitrates pollution represents nowadays a serious issue related to the quality of groundwater; continuous growth of industrial-scale agricultures lead to an increase of nitrates content in groundwater in the last years. Several technologies have been validated as capable to promote in situ biological nitrates remediation, such as permeable reactive barriers (PRB), biotrench, biobarriers etc. These technologies are all characterised by the use of organic substrate that act as a slow release carbon source. In free dissolved oxygen absence, such organic carbon is further oxidised, by heterotrophic bacteria naturally present in soil, in compliance to anoxic metabolism by using nitrates bound oxy…
