Akustische Masken auf dem Theater/ Maschere acustiche in teatro: Text - Sprache - Performanz/ Testo - Lingua - Performance

2019

I molteplici interessi scientifici e professionali - teatrologici, storici, linguistici, derivanti dall'attuale prassi attoriale e registica - che sono alla base di questi saggi offrono un quadro sfaccettato e complesso delle riflessioni sul discorso della comunicazione teatrale nei due paesi, le cui peculiarita, piu che le somiglianze, spiccando nel confronto, gettano una luce incrociata particolarmente interessante. Il filo rosso che si intreccia alla trama di questi contributi e senz'altro il complesso rapporto che lega la parola del testo teatrale con quella che si realizza sulla scena, ovverosia cio che in realta si puo definire lo specifico dell'evento teatrale in se, il quale si real…

Occurrence and risk assessment of mycotoxins, acrylamide, and furan in Latvian beer.

2018

This work reports data on the occurrence of nine mycotoxins and two food processing contaminants - acrylamide and furan - in a total of 100 beers produced in Latvia. Mycotoxins were detected by high-performance liquid chromatography (HPLC) coupled with time-of-flight mass spectrometry, acrylamide by HPLC coupled with quadrupole-Orbitrap mass spectrometry, and furan by headspace gas chromatography-mass spectrometry. The most frequently occurring mycotoxins were HT-2 and deoxynivalenol (DON), which were detected in 52% and 51% of the analysed samples. The highest content was observed for DON, reaching the maximum of 248 µg kg-1. Furan was ubiquitous, and 74% of the samples contained acrylamid…

L'émergence du référentiel marchand dans la tarification des cliniques privées algériennes : privatisation du financement et changement de paradigme

2021

La convergence tarifaire participe à la privatisation progressive du système de santé algérien amorcée depuis la fin des années 80. Le passage d’une logique de gratuité à une logique marchande pour accéder aux soins représente un bouleversement pour les patients. Afin d’appréhender la formation des tarifs dans le secteur de l’hospitalisation privée, nous avons mixé une enquête qualitative par entretiens semi-directifs auprès de 16 fondateurs de cliniques privées et l’administration d’un questionnaire auprès de 40 médecins permanents de ces cliniques disposant d’une activité à plein temps. Nos résultats montrent que l’absence d’une grille officielle de tarification des prestations de soins a…

A preliminary study on the stability of benzodiazepines in blood and plasma stored at 4 degrees C.

1997

An approach to determine the stability of benzodiazepines and some of their metabolites (n = 13) by means of a routinely applied gas chromatographic method using electron capture detection was made in this preliminary study. Validation data of the method are given. Spiked blood and plasma samples were stored at 4 degrees C and analysed at selected times up to 240 days. The concentrations of all analytes had decreased to at least 60% of the original levels at the end of the observation period. A clear pattern of breakdown could not be established. The data obtained suggest that results from long-term stored samples should be interpreted cautiously. Further investigations concerning the stabi…

Toxicity assessment and biodegradation potential of water-soluble sludge containing 2,4,6-trinitrotoluen

2013

The water-soluble phase of trinitrotoluene-containing sludge (SLP) was characterized with regard to trinitrotoluene (TNT) concentration, ecotoxicity, and a model biodegradation experiment as evaluation criteria for further development of appropriate treatment technologies. SLP contained 67.8 mg TNT/l. The results of germination and root-elongation tests indicated that SLP had a species-specific phytotoxic effect. The results of a 21 day degradation experiment demonstrated TNT conversion to 4-amino-2,6-DNT and 2-amino-4,6-DNT, with a simultaneous reduction in the total concentration of nitroaromatics. Addition of inoculum stimulated the TNT degradation process. The presence of the sludge sol…

Coffee and endothelial function: a battle between caffeine and antioxidants ?

2010

Although coffee is largely consumed by adults in Western countries, controversy exists about its impact on the cardiovascular system. We recently demonstrated that caffeinated and decaffeinated espresso coffee have different acute effects on endothelial function in healthy subjects, measured using flow-mediated dilation (FMD) of the brachial artery. In this study, we measured the anti-oxidant capacity of two coffee substances in terms of free stable radical 2,2-diphenyl-1-picryl-hydrazyl 50% inhibition (I(50) DPPH). The caffeinated coffee had a slightly higher anti-oxidant capacity than decaffeinated espresso coffee (I(50) DPPH: 1.13±0.02 vs 1.30±0.03 μl; P0.001). We suggest that the unfavo…

Accelerated Solvent Extraction and Pulsed Electric Fields for Valorization of Rainbow Trout (Oncorhynchus mykiss) and Sole (Dover sole) By-Products: …

2021

Fishery by-products are rich in biologically active substances and the use of green and efficient extraction methods to recover these high-added-value compounds is of particular importance. In this study, head, skin and viscera of rainbow trout and sole were used as the target matrices and accelerated solvent extraction (ASE) (45–55 °C, 15 min, pH 5.2–6.8, 103.4 bars) and pulsed electric fields (PEF) (1–3 kV/cm, 123–300 kJ/kg, 15–24 h) were applied as extraction technologies. The results showed that ASE and PEF significantly increased the protein extract efficiency of the fish by-products (p < 0.05) by up to 80%. SDS-PAGE results showed that ASE and PEF treatments changed the molecular size…

Biothiols, taurine, and lipid-soluble antioxidants in the edible pulp of Sicilian cactus pear (Opuntia ficus-indica) fruits and changes of bioactive …

2005

Biothiols, taurine, and flavonols, as well as tocopherols and carotenoids have been assessed in the edible pulp of Sicilian red (Sanguigna), yellow (Surfarina), and white (Muscaredda) cultivars of cactus pear. The yellow cultivar has the highest level of reduced glutathione (GSH, 8.1 +/- 0.78 mg/100 g pulp), whereas the white cultivar showed the highest amount of cysteine (1.21 +/- 0.12 mg/100 g pulp). Taurine accounted for 11.7 +/- 1.0 mg/100 g in the yellow pulp, while lower levels were measured in the others. With the exception of kaempferol in the yellow cultivar (2.7 +/- 0.2 microg/100 g pulp), the edible pulp of cactus pear was not a source of flavonols. Very low amounts of lipid-solu…
