An analytical method for monitoring micro-traces of landfill leachate in groundwater using fluorescence excitation–emission matrix spectroscopy

2016

In this study, we use three-dimensional excitation-emission matrix (EEM) fluorescence spectroscopy for the identification of contamination of natural water bodies by landfill leachate. In particular, EEM was applied to provide information about the presence and quantities of leachate in ground waters. A good linear relationship was found between the fluorescence intensity emission of groundwater spiked with landfill leachate and the volumes of the latter, suggesting that there was no intrinsic fluorescence in the concentration range of 0-1000 μL L-1. The obtained values of the LOD (10 μL L-1; TOC = 34 μg L-1) and LOQ (34 μL L-1; TOC = 114 μg L-1) allow us to detect the presence and the amou…

Applications of conduction calorimetry to the setting reaction of zinc phosphate dental cement

1999

The kinetics of the exothermic setting reaction of zinc phosphate dental cement can be successfully investigated by conduction calorimetry. The primary objective of this study is to examine the effects arising from the addition of various additives to the liquid and calcination of cement powder. The rate of heat evolution versus time shows the occurrence of merely one maximum. In the case of unmodified orthophosphoric acid a sharp peak occurs early after onset of mixing due to the formation of crystalline α-hopeite. Commercial cement liquids contain aluminum and zinc. From the calorimetric curves it has been found that these cations act as a setting retarders, and ensure sufficient working …

Hate Speech e messaggi discriminatori: riflessioni internazionalistiche sul caso Casapound c. Facebook

2021

In this intervention the idea is submitted that the interim measures in the case Casapound v. Facebook, by means of which Fb Ireland was ordered by the Rome Tribunal (on December 12, 2019) to reactivate the profile of the extreme right wing political association Casapound - previously closed as a consequence of an alleged violation of fb standards concerning hate speech - can be criticized under international and european law. Such criticisms stem both from the overall picture of the international and european legal standards concerning hate speech (par. 2) and from the relevant case law of the European Court of Human rights (paras. 3 and 4).

"She's straight, you delusional cunt!" : a study on bullying and homophobia in online fandoms

2016

Tämä kandidaatintutkielma käsittelee seksuaalisten vähemmistöjen syrjintää ja nettikiusaamisen esiintymistä internet-faniyhteisöissä. Edelliset tutkimukset kertovat nettikiusaamisen olevan haitallista ja vaikuttavan uhrien mielenterveyteen – usein jopa enemmän kuin kasvotusten tapahtuva kiusaaminen. Tutkielmaa varten tehty nettikysely suunnattiin “femslash”-faniryhmille. Näiden ryhmien median kulutukseen kuuluvat esimerkiksi tv-ohjelmien naishahmojen väliset (romanttiset) suhteet ja näistä suhteista puhuminen sekä eri materiaalien (kuten kuvien, videoiden ja fanifiktion) luominen ryhmien henkilöiden kesken. Kyselyn perusteella oli tarkoitus saada selville, miten yleistä näiden ryhmien kokem…

Water Depollution by Advanced Oxidation Technologies

2020

This chapter deals with water treatments by advanced oxidation processes (AOPs) based on chemical and photochemical reactions. The most used processes are described, and for each of them, the main reaction mechanisms, principles, advantages, drawbacks, performances and formation of by-products, coupled with technologies and their applications to waters and wastewater depollution, have been analysed, supporting the main results of studies published in the pertinent literature.

Flow cytometric kinetic assay of calcium mobilization in whole blood platelets using Fluo-3 and CD41

1999

Background: Platelet activation plays a major role in the physiology and pathology of hemostasis. Flow cytometry is a promising approach for the structural and functional analysis of platelets. However, the choice of adequate biological parameters and most technical issues are still under discussion. A rise in cytosolic free Ca 21 is a key early event that follows platelet stimulation and precedes several activation responses, including shape change, aggregation, secretion, and expression of procoagulant activity. Our objective was to set up a fast and sensitive flow cytometric method to determine the kinetics of intracellular Ca 21 mobilization in platelets, which could be performed with t…

Gold nanoclusters for ratiometric sensing of pH in extremely acidic media.

2019

AuNCs capped with β-nicotinamide adenine dinucleotide phosphate exhibit an outstanding performance as fluorescent pH sensors; specifically they exhibit a high emission in strongly acidic media and linear dependence on pH in extremely acidic media (0.6–2.7) as well as in the 7.0–9.2 pH range, while they are unresponsive at intermediate pH values. Remarkably, these AuNCs make ratiometric sensing possible in extremely acidic media with a single fluorophore, specifically the nanocluster itself.

Fructose-1,6-Bisphosphate Protects Hippocampal Rat Slices from NMDA Excitotoxicity

2019

Effects of fructose 1,6-bisphosphate (F-1,6-P2) towards N-methyl-d-aspartate NMDA excitotoxicity were evaluated in rat organotypic hippocampal brain slice cultures (OHSC) challenged for 3 h with 30 &mu

A novel method for determination of inorganic polyphosphates using the fluorescent dye fura-2.

1997

A method for determining inorganic polyphosphate, which is based on the Mn2+-induced quenching of the fluorescence of the calcium indicator fura-2, is described. The effect of Mn2+ ions on fura-2 fluorescence is gradually abolished in the presence of increasing concentrations of polyphosphate; this allows the quantification both of synthetic polyphosphates and of the naturally occurring polymer isolated from tissues or cells. The described method has some advantages compared to conventional procedures for detection of polyphosphates based on the metachromatic effect on toluidine blue. It can be applied for the determination of pyrophosphate, tripolyphosphate and other short-chain polyphosph…
