A novel analytical approach has been performed and evaluated for the identification quantification of phenolic compounds (phenolic alcohols, secoiridoid derivates, lignans, flavonoids, acids aldehydes) which can be found in both virgin olive oil (VOO) extra (EVOO). An improved liquid–liquid micro extraction (LLME) method combining with ultra high performance liquid chromatography (UHPLC) coupled to electrospray ionization source (ESI) tandem mass spectrometry (MS/MS) Dynamic Multiple...

Recently, narrative has emerged as an important concept in interrupting the transmission of intergenerational trauma Indigenous communities. For many peoples, form storytelling is a fundamental traditional cultural practice. This article presents findings from community-based digital (DS) workshop that focused on eliciting stories resiliency amidst historical (HT) Māori community. The principal investigator worked with community members to create strengths. Post-workshop in-depth interviews...

Abstract The growth of cultivation (strawberries and citrus fruits) in the coastal region Huelva province Spain last 10 years has meant an increase demand water from Ayamonte‐Huelva aquifer system. It also introduction excess nitrogen via fertilizers farming. system now two problems: salt‐water intrusion southern sector (González Romero, 1991; González, 1992); a general nitrate content saturated zone. This second problem led to average concentrations nitrates above potable limits (50 ppm),...

In the present work, Acid Mine Drainage (AMD) processes in Chorrito Stream, which flows into Cobica River (Iberian Pyrite Belt, Southwest Spain) are characterized by means of clustering techniques based on fuzzy logic. Also, pH behavior contrast to precipitation is clearly explained, proving that influence rainfall inputs acidity and, as a result, metal load riverbed undergoing AMD highly depends moment when it occurs. general, dynamic response sum instant stimuli produced isolated rainfall,...

A procedure for the separation and determination of inorganic species antimony based on use coupled high-performance liquid chromatography (HPLC) hydride generation (HG) atomic fluorescence spectrometry (AFS) is described. Sb(III) Sb(V) were separated a miniaturized anion-exchange column (Supelcosil LC-SAX 1, 2 cm × 4.6 mm id) using 0.06 mol l−1 ammonium tartrate aqueous solution at pH 6.9 as eluent. The retention times 0.45 3.5 min Sb(III), respectively. hydrides generated on-line with 3%...

An arsenic speciation study has been performed in the headwaters of Tinto River, representing an environment heavily polluted Acid Mine Drainage originated by Iberian Pyrite Belt. The variables considered this were species, pH, redox potential, conductivity, temperature, rainfall and concentrations metals such as Fe, Cu Zn. results obtained from classical statistical treatment confirm extreme acidity high metals, sulfates species (mean values 2.3 for 1.10 mg L−1 Cd, 325.4 Cu, 1241.1 241.2...

ABSTRACT The influence of different storage conditions on the volatile composition young white wine was evaluated during 1 year storage. bottled and stored under temperature, position illumination. During storage, a significant increase in total content esters (mainly due to ethyl butyrate, acetate diethyl succinate) acids detected. Also alcohols carbonyl compounds decreased Storage time, temperature illumination have effect content, whereas are affected by is Stepwise linear discriminant...
