Hydrogeochemistry and stable isotopes of thermal springs: earthquake-related chemical changes along Belice Fault (Western Sicily)
2001
Abstract Three geothermal systems, Montevago, Castellammare-Alcamo and Sciacca, are located along the main seismogenetic structures in Western Sicily. Concentrations of dissolved species including the gases CO 2 , N 2 , He and the results of stable isotope measurements δ 18 O, δ D and δ 13 C TDIC in water samples collected from six thermal springs and 28 cold discharges were used to characterise their feeder aquifers and to reveal the relationships between water chemistry and regional seismicity. The Sciacca thermal springs differ chemically and isotopically from those of Montevago and the Castellammare-Alcamo areas. The inferred deep end-members of the thermal waters of Montevago and Caste…
Recreational use of water storage reservoir in the municipality of Kluczbork
2015
Water storage reservoir in the Kluczbork municipality in Ligota Zamecka is located on the Stobrawa river. In 1997 the river flooded surrounding towns and villages. It was decided to build a reservoir that during successive flood states would protect residents. The aim of this study is to analyze the possibility of using water reservoir in Kluczbork municipality for recreation and tourism purposes. The results of two surveys conducted among residents of Ligota Zamecka have been analyzed. The residents could express their opinion about the project. The first questionnaire was conducted at the time when local community was only aware of the project to build retention and recreation reservoir i…
Changes in vegetation spring dates in the second half of the twentieth century
2011
This study aims at estimating trends in spring phenology from vegetation index and air temperature at 2 m height. To this end, we have developed a methodology to infer spring phenological dates from Global Inventory Modeling and Mapping Studies GIMMS Normalized Difference Vegetation Index NDVI time-series, which are then extrapolated to the period 1948–2006 with the help of Reanalysis data, using its 2 m height air temperature parameter. First, yearly NDVI is fitted to a double-logistic function for the whole extent of the GIMMS database 1981–2003. This fitting procedure allows us to describe, on a yearly basis, the NDVI evolution for each pixel through the estimation of six parameters whic…
Improvement of the technological process of carbonated spring water by implementing the quality and food safety management standards
2019
Bottled spring water must be health providing, clean, without microorganisms, parasites or substances. The design, manufacturing and management of processes, related to spring water bottling involves controlling the safety issues that may arise in the production processes. These aspects are not sufficient to prevent hazards and they must be related to the implementation of a quality and food safety systems. The aim of the paper is to improve the technological process of carbonated spring water in Monopolis S.A Company, by implementing the quality and food safety management standards. The methodology is based on the implementation requirements of the HACCP principles, included in ISO 22000 s…
CO2 release to the atmosphere from thermal springs of Sperchios Basin and northern Euboea (Greece): The contribution of “hidden” degassing
2020
Abstract Greece is a region characterised by intense geodynamic activity that favours the circulation of hydrothermal fluids in the crust transporting volatiles from either the deep crust or the mantle to the surface. Elevated heat flow values are detectable at Sperchios Basin and North Euboea (central Greece), two areas defined by a system of deeply rooted extensional faults and Quaternary volcanic activity. This setting contributed to the formation of numerous hydrothermal systems, which are mostly expressed as CO2-rich thermal springs with intense bubbling. The CO2 output from six bubbling pools has been determined by flux measurements with the use of the floating chamber method. The hig…

Heat wave occurrences over Senegal during spring: regionalization and synoptic patterns.
2020
18 pages; International audience; Based on 12 Senegalese stations of the Global Summary of the Day (GSOD) database (1979–2014), heat waves (HW) are defined for each station in spring (March–April–May, the hottest season in Senegal) as the daily maximum temperature (Tx), minimum temperature (Tn), or average apparent temperature of the day (AT), exceeding the corresponding 95% mobile percentile for at least three consecutive days. A hierarchical cluster analysis used to regionalize HW in these 12 stations is applied to simultaneous occurrences of daily temperature peaks over their 95% mobile percentiles. Three homogeneous zones of four stations each are identified (Zone 1, Zone 2 and Zone 3),…
Prenatal Exposure to Δ9-Tetrahydrocannabinol Affects Hippocampus-Related Cognitive Functions in the Adolescent Rat Offspring: Focus on Specific Marke…
2023
Previous evidence suggests that prenatal exposure to THC (pTHC) derails the neurodevelopmental trajectories towards a vulnerable phenotype for impaired emotional regulation and limbic memory. Here we aimed to investigate pTHC effect on hippocampus-related cognitive functions and markers of neuroplasticity in adolescent male offspring. Wistar rats were exposed to THC (2 mg/kg) from gestational day 5 to 20 and tested for spatial memory, object recognition memory and reversal learning in the reinforce-motivated Can test and in the aversion-driven Barnes maze test; locomotor activity and exploration, anxiety-like behaviour, and response to natural reward were assessed in the open field, elevate…
La perspectiva de Springboard: país trampolín y filial trampolín. Una nueva alternativa para el proceso de internacionalización
2014
Cuando la firma inicia su proceso de internacionalización el principal problema que enfrenta es el de la distancia (Johanson y Vahlne, 1977) y después, cuando desarrolla actividades de inversiones productivas en los mercados internacionales, surge el problema de ser extranjero (Hymer, 1960). El desarrollo de un nuevo camino estratégico en los negocios internacionales resulta de vital importancia pero más aún, el desarrollo de un instrumento, medidas objetivas y un plan de ruta, son fundamentales para que los gerentes comprometan sus recursos en la generación de conocimientos específicos, desarrollo de habilidades, creación de ventajas competitivas sostenibles y legitimidad en los mercados e…
Preliminary study on the unusual properties in the habitat of Ranunculetum baudotii in Central Europe
2011
Abstract The study examines the patches of the saltwater association Ranunculetum baudotii in a new, atypical site; i.e., located more than 400 km away from the Baltic coastal line. They were found in a karst spring, and were the first locality of the community identified in Poland. The water and sediments within the patches were analyzed chemically in the laboratory, but, conductivity, water temperature and O2 content were measured in the field. The spring was determined to be a relatively stable aquatic habitat, with a typical chemical composition of subterranean water (a prevalence of hydro-carbonate, calcium and magnesium ions), and rich, e.g., in nitrogen and phosphorus, and disturbed …
