The working partner in family enterprise : European and national issues
2021
The essay focuses on the discipline of the work done by one partner in the company of the other in cross-border couples and on the problems involved in this case. More specifically the focus is on the hermeneutical problems that arise both at the level of European legislation and at the level of Italian national discipline which is applicable according to European conflict criteria, showing the ambiguities and wide areas of shadow left uncovered by the latter.
Las obras musicales en las radios universitarias
2018
The Spanish General Audiovisual Communication Law does not relate to Campus Radio Stations. In this context, Copyright Collection Societies do not cover them in their catalogues of general fees. For this reason, the holders of these radios are forced to negotiate them. Althoug the Intellectual Property Law and the Order ECD/2574/2015, of 2 December, contain obligations for Copyright Collection Societies, on this matter its enforcement are far from being achieved
Primeras consideraciones a la Ley Orga?nica 3/2021, de 24 de marzo, de regulación de la eutanasia. el reconocimiento de un nuevo derecho
2021
The aim of this paper is to carry out a brief study of the recent Organic Law 3/2021, of March 24, on the regulation of euthanasia (BOE. March 25, 2021) approved in Spain, from a constitutional perspective, highlighting its main aspects. The matter under study is not exempt from controversy because it covers legal, medical and ethical considerations of great complexity.
Chemical Composition and antimicrobial activity of the essential oils from two species of Thimus growing wild in southern Italy
2009
The volatile constituents of the aerial parts of two samples of Thymus longicaulis C. Presl, collected in Campania and in Sicily, and two samples of Thymus pulegioides L. from the same regions, were extracted by hydrodistillation and analyzed. Considering the four oils together, seventy-eight different compounds were identified: 57 for Thymus longicaulis from Sicily (91.1% of the total oil), 40 for Thymus longicaulis from Campania (91.5% of the oil), 39 for Thymus pulegioides from Sicily (92.5% of the oil) and 29 for Thymus pulegioides from Campania (90.1% of the oil). The composition of the oils is different, although the most abundant components are identical in T. pulegioides. The essent…
Proximate Composition and Nutritional Value of Three Macroalgae: Ascophyllum nodosum, Fucus vesiculosus and Bifurcaria bifurcata
2017
Proximate composition (moisture, protein, lipid and ash content) and nutritional value (fatty acid, amino acid and mineral profile) of three macroalgae (Ascophyllum nodosum, Fucus vesiculosus and Bifurcaria bifurcate) were studied. Chemical composition was significantly (p < 0.001) different among the three seaweeds. In this regard, the B. bifurcata presented the highest fat content (6.54% of dry matter); whereas, F. vesiculosus showed the highest protein level (12.99% dry matter). Regarding fatty acid content, the polyunsaturated fatty acids (PUFAs) were the most abundant followed by saturated fatty acids (SFAs) and monounsaturated fatty acids (MUFAs). On the other hand, the three seawe…
Chemical Compositions and Antioxidant Activities of Essential Oils, and Their Combinations, Obtained from Flavedo By-Product of Seven Cultivars of Si…
2022
In this work, seven Citrus aurantium essential oils (EOs) derived from flavedo of cultivars ‘Canaliculata’, ‘Consolei’, ‘Crispifolia’, ‘Fasciata’, ‘Foetifera’, ‘Listata’, and ‘Bizzaria’ were investigated. EOs were also combined in 1:1 (v/v) ratio to identify possible synergism or antagonism of actions. GC-MS analysis was done to investigate Eos’ phytochemical profiles. The antioxidant activity was studied by using a multi-target approach based on FRAP, DPPH, ABTS, and β-carotene bleaching tests. A great difference was observed in EOs’ phytochemical profiles. d-limonene (33.35–89.17%) w…
Antitumor Mechanism of the Essential Oils from Two Succulent Plants in Multidrug Resistance Leukemia Cell
2019
Drug resistance remains a major challenge in the treatment of cancer. The multiplicity of the drug resistance determinants raises the question about the optimal strategies to deal with them. Essential oils showed to inhibit the growth of different tumor cell types. Essential oils contain several chemical classes of compounds whose heterogeneity of active moieties can help prevent the development of drug resistance. In the present paper, we analyzed, by gas chromatography-mass spectrometry the chemical composition of the essential oil of the leaves of Kalanchoe beharensis obtained by hydrodistillation and compared the chemical composition of its essential oil with that of Cyphostemma juttae.…
Genesi geometrica delle volte centriche
1996
Un'analisi completa degli organismi voltati comporta lo studio delle molteplici componenti necessarie alla loro definizione: configurazione geometrica, sistema costruttivo, area storico-geografica di appartenenza, interpretazioni Stilistiche. L’obiettivo di questo studio è indirizzato all' analisi delle volte continue su pianta centrica definibili attraverso le leggi della geometria euclidea. L’indagine si pone all'interno dei confini relativi alla loro configurazione geometrica e il criterio adottato, svincolato da classificazioni di carattere tipologico o stilistico, propone l'identificazione di famiglie geometriche in base alla figura del poligono di base dell'impianto. Si può identifica…
Die Glucuronidbildung nach peroraler Belastung mit Acetanilid bei chronischer Hepatitis und Lebercirrhose
1966
Je 12 Patienten mit laparoskopisch und histologisch gesicherter chronischer Hepatitis und Lebercirrhose erhielten peroral 800 bzw. 1200 mg Acetanilid. Als Kontrolle dienten altersmasig entsprechende Lebergesunde. 2, 6 und 24 Std nach der Belastung wurden das freie und das an Glucuronsaure gebundene N-acetyl-p-aminophenol im Serum und im 24 Std-Urin bestimmt. Auserdem wurde versucht, freies, unverandertes Acetanilid nachzuweisen. Im Urin wurde ferner die Konzentration des total konjugierten N-acetyl-p-aminphenols gemessen. Bei Patienten mit chronischer Hepatitis und Lebercirrhose waren besonders nach 1200 mg Acetanilid eine Verminderung des Glucuronids und eine Zunahme der freien Verbindung …
Abundance of narG , nirS , nirK , and nosZ Genes of Denitrifying Bacteria during Primary Successions of a Glacier Foreland
2006
ABSTRACT Quantitative PCR of denitrification genes encoding the nitrate, nitrite, and nitrous oxide reductases was used to study denitrifiers across a glacier foreland. Environmental samples collected at different distances from a receding glacier contained amounts of 16S rRNA target molecules ranging from 4.9 × 10 5 to 8.9 × 10 5 copies per nanogram of DNA but smaller amounts of narG , nirK , and nosZ target molecules. Thus, numbers of narG , nirK , nirS , and nosZ copies per nanogram of DNA ranged from 2.1 × 10 3 to 2.6 × 10 4 , 7.4 × 10 2 to 1.4 × 10 3 , 2.5 × 10 2 to 6.4 × 10 3 , and 1.2 × 10 3 to 5.5 × 10 3 , respectively. The densities of 16S rRNA genes per gram of soil increased with…
