Investigation of the physiological impact and the mode of action of the pyoverdine from Pseudomonas fluorescens on Arabidopsis thaliana : links with …
2015
Siderophores are strong iron chelators produced by bacteria under iron deficiency conditions. In the present work, we studied the impact of the siderophore pyoverdine, produced by the plant growth promoting rhizobacteria Pseudomonas fluorescens C7R12, on plant physiology from phenotypic to molecular effects with a specific focus on plant growth, immune response and iron homeostasis. Based on our analysis of the mode of action of the non-protein amino acid β-aminobutyric acid (BABA), a priming inducer in plants, we studied more specifically the functional link between iron homeostasis and plant immunity. Under iron deficiency, P. fluorescens excretes the iron free form of pyoverdine (apo-pyo…
Herbicidal potential of aqueous extracts from Melia azedarach L., Artemisia arborescens L., Rhus coriaria L. and Lantana camara L.
2017
In the search for new strategies for weed management in agricultural systems, a great interest is to use the plant extracts to replace or integrate, chemical weed control. Two experiments were done to test the effects of plant water extracts from Chinaberry (Melia azedarach L.), Tree Wormwood (Artemisia arborescens (Vaill.) L.), Sicilian Sumac (Rhus coriaria L.) and Lantana (Lantana camara L.) on seed germination of Rocket (Eruca sativa Mill.), Rapeseed (Brassica napus L.), Bladderflower (Araujia sericifera Brot.) and Psyllium (Plantago psyllium L). The water extracts (pure and 50% mixtures) from the donor species were applied on seeds of recipient plants. In second experiment in pots, thes…

1200 years of decadal-scale variability of Mediterranean vegetation and climate at Pantelleria Island, Italy.
2013
A new sedimentary sequence from Lago di Venere on Pantelleria Island, located in the Strait of Sicily between Tunisia and Sicily was recovered. The lake is located in the coastal infra-Mediterranean vegetation belt at 2 m a.s.l. Pollen, charcoal and sedimentological analyses are used to explore linkages among vegetation, fire and climate at a decadal scale over the past 1200 years. A dry period from ad 800 to 1000 that corresponds to the 'Medieval Warm Period' (WMP) is inferred from sedimentological analysis. The high content of carbonate recorded in this period suggests a dry phase, when the ratio of evaporation/precipitation was high. During this period the island was dominated by thermop…

In the places of “Fragmenta”
2021
Leggere i testi, le riflessioni e le digressioni, che catturano il lettore nella loro complementarità, significa seguire “piste” di curiosità. La nuova iniziativa editoriale della Bramea Editore riflette l’intento d’interpretare il fare architettura con dei libri che guardano il campo della cultura del progetto, dell’architettura con un raggio d’azione internazionale. Ed è proprio attraverso questa unità di intenti, ravvisabile nella progettualità editoriale della Bramea, che si fondano alcuni presupposti di riconoscibilità. I testi contenuti nei libri aprono uno scenario dove si collocano i progetti e dove l’“architetto militante” è protagonista. In quest’area culturale si muove “Fragmenta…

Large-scale Cosmic-Ray Anisotropies above 4 EeV Measured by the Pierre Auger Observatory
2018
We present a detailed study of the large-scale anisotropies of cosmic rays with energies above 4 EeV measured using the Pierre Auger Observatory. For the energy bins [4,8] EeV and $E\geq 8$ EeV, the most significant signal is a dipolar modulation in right ascension at energies above 8 EeV, as previously reported. In this paper we further scrutinize the highest-energy bin by splitting it into three energy ranges. We find that the amplitude of the dipole increases with energy above 4 EeV. The growth can be fitted with a power law with index $\beta=0.79\pm 0.19$. The directions of the dipoles are consistent with an extragalactic origin of these anisotropies at all the energies considered. Addi…
Atbildība par nelikumīgām darbībām sportā
2019
Šī darba temats ir atbildība par nelikumīgām darbībām sportā, konkrētāk, par manipulācijām ar sporta sacensībām un antidopinga noteikumu pārkāpumiem, skatoties uz faktu, ka par pirmo Krimināllikumā iekļauts atsevišķs pants, bet par dopinga lietošanu nav un kriminālatbildību iespējams piemērot tikai ļoti retos gadījumos. Tālākai tēmas analīzei būtiski izprast jēdzienu saturu, šo darbību praktisko izpausmi un ietekmi uz sportistu tiesībām, interesēm, kā arī uz sabiedrību kopumā. Bakalaura darba mērķis ir apskatīt minēto neatļauto rīcību aktualitāti Latvijā, regulējumu un tā atbilstību starptautiskajiem tiesību aktiem, kā arī regulējumu ārvalstīs, kurās par manipulācijām ar sporta sacensībām u…
