OPTIMIZING STOCHASTIC SUSCEPTIBILITY MODELLING FOR DEBRIS FLOW LANDSLIDES: MODEL EXPORTATION, STATISTICAL TECHNIQUES COMPARISON AND USE OF REMOTE SEN…
Il presente lavoro di ricerca è stato sviluppato al fine di approfondire approcci metodologici nell'ambito della sucscettibilità da frana. In particolare, il tema centrale della ricerca è rappresentato dal tema specifico dell'esportazione spaziale di modelli di suscettibilità nell'area mediterranea. All'interno del topic specifico dell'esportazione di modelli predittivi spaziali sono state approfondite tematiche relative all'utilizzo di differenti algoritmi o di differenti sorgenti, derivate da DEM o da coperture satellitari. The present work has been developed in order to enhance current methodological approaches within the big picture of the landslide susceptibility. In particular, the ce…

Effect of conditioned media on three genotypes ofDrosophila melanogaster: Physical, chemical, and biological aspects
1986
The uric acid contents in larvae, pupae, and culture media were studied during larval and pupal development in three genotypes of Drosophila melanogaster reared in both crowded and noncrowded conditions. The uric acid content and the response of genotypes in media supplemented with 10 and 15 mg/ml of uric acid were correlated with the outcome obtained in conditioned media. In addition, the behavior of genotypes in conditioned media is explained in terms of the physicochemical properties of the conditioned media, which include uric acid content, the amount of food ingested, the degree of free water, the physical disturbance within the cultures, and the particular response of each genotype to…
Larva-to-adult and pupa-to-adult mortality dynamics in crowded cultures ofDrosophila melanogaster
1985
Pupal mortality is shown here to bear the main responsibility for total mortality duringDrosophila melanogaster development in crowded conditions. The dynamics of the pupa-to-adult and larva-to-adult processes of mortality follows a S-shaped logistic model, like survival in density-dependent processes. Data given here confirm to some extent Wallace's suggestion that pupal mortality is a density-dependent process.
Larval competition in Drosophila melanogaster: frequency-dependence of viability
1988
The application of the overfeeding technique (interruption of the competition during larval development) to the study of larval competition in two-strain cultures of Drosophila melanogaster demonstrates the following points: (1) viability is a function of competition time; (2) viability becomes more frequency-dependent as competition time increases; (3) the dynamics of the “inner” subpopulation (adults that have passed all their development in a crowded condition) and “outer” subpopulation (adults coming from larvae recovered by interruption of competition) vary with time as regards frequency-dependence; and (4) the wild type strain Oregon is the active agent in competition with the strain …
Intra- and intergenotypic larval competition in Drosophila melanogaster : effect of larval density and biotic residues

Vegetation and climate in the eastern Iberian Peninsula during the pre-evaporitic Messinian (late Miocene). Palynological data from the Upper Turolia…
2015
International audience; The present paper reports a complete palynological study of the Upper Turolian sediments outcropping at the Venta del Moro site (eastern Iberian Peninsula). The pollen assemblages observed mainly reflect the local and regional vegetation, which must have formed part of a wetland ecosystem within a general setting of open steppe, as indicated by the great abundance and diversity of herbaceous pollen. This reflects the persistence of open vegetation in the Iberian Peninsula after the Middle Miocene when it became extensive. We here report the most recent record of Disanthus for the Iberian Peninsula. This shrub played an important role in an unusual, edaphically-mediat…
Latvijas reģionu attīstība un to nevienlīdzības analīze
2022
Reģionu attīstība, reģionu un to novadu starpā pastāvošā nevienlīdzība ir aktuāla problēma ar ko saskaras ne tikai Latvija, bet arī citas pasaules valstis, kad ir vērojamas krasas atšķirības reģionu starpā ekonomiskajos un demogrāfiskajos rādītājos. Šī problēma izceļas ar krasām atšķirībām reģionu starpā ekonomiskajos un demogrāfiskajos rādītājos. Un lai gan ir dažādas atšķirības starp valsts reģioniem, tos visus ietekmē iedzīvotāju skaita samazināšanās tendence, kas arī ir aktuāla problēma Latvijas valstī. Bakalaura darba mērķis ir ir noskaidrot, kādas sakarības pastāv starp Latvijas vairāk attīstītajiem un ne tik attīstītajiem novadiem, ar klasteru analīzes metodi sagrupējot Latvijas nova…
Influences on Master’s Degree Students’ Economic Knowledge
2020
Despite the growing body of research, little is known about students’ economic knowledge at the beginning of, or at various points throughout, their master’s degree programs. In this study different impact factors on students’ microeconomic knowledge are tested. Based on the “utilization of learning opportunities model” by Helmke we focus on 1) individual and sociodemographic characteristics of the students, 2) their learning potential and study-related characteristics and 3) the characteristics and structure of their learning environment. For each of the three influencing factors we used different indicators that were expected to correlate with students’ knowledge. We tested the assumption…
Balkanskie puti lesninskich monachin'
2012
The immigration of the Lesna Monastery nuns from the west side of Imperial Russia to other Russian Empire territories, to Serbia and to France is part of the Russian emigration history. The stay of the nuns of Lesna in the territory of the actual Republic of Macedonia, in the monastery of St. Bogorodica in Kicevo, is a less known event of the history of their migration.
