Krievijas akciju tirgus pievilcības novērtējums salīdzinājumā ar ASV akciju tirgu
2021
Akciju tirgus ir svarīga ekonomikas sastāvdaļa. Mūsdienās ASV akciju tirgus tiek uzskatīts par lielāko pasaulē. Pasaulē ir pietiekami attīstīti akciju tirgi, tomēr ne visi no tiem tiek pietiekami novērtēti. Šī pētījuma mērķis ir pierādīt ka Krievijas akciju tirgus nav pietiekami novērtēts, veicot Krievijas akciju tirgus salīdzinošo analīzi ar ASV akciju tirgu. Izvērtēt Krievijas akciju tirgus pozitīvās un negatīvās īpašības.. Pirmajā nodaļā tiek analizēta akciju tirgus teorētiskie pamati. Otrajā nodaļā tiek aprakstīti Krievijas un ASV akciju tirgi, to vēsturiskā attīstība. Trešajā nodaļā tiek analizēta Krievijas akciju tirgus darbība un to ietekmējošie faktori.
Early Warning Systems for Food Security in West Africa: Evolution, Achievements and Challenges
2010
In West Africa, early warning systems (EWSs) for food security have been widely recognized to have contributed, in the last 20 years, to an improved ability to deal with famine emergencies. Nevertheless, despite the advancements in understanding of the environmental and socio-economic dynamics and despite the improved technologies, tackling food security remains a difficult task for decision makers as demonstrated by local food crises in many countries of the region. African Monsoon Multidisciplinary Analysis, while improving the understanding of the monsoon system, allowed us to better orient research challenges to provide EWS with improved products, effectively meeting the needs of end-us…

SEA-LEVEL AND CLIMATIC CHANGES DURING THELAST 41,000 YEARS IN THE OUTER SHELF OF THE SOUTHERN TYRRHENIAN SEA: EVIDENCE FROM FORAMINIFERA AND SEISMOST…

Reply to comment by C. Morhange, C. Flaux, P.A. Pirazzoli, M.B. Carre on “Holocene Sea level Change in Malta”
2013
The pits of Birzebbugia are located near the present-day mean sea level, and some are partially submerged. They were dated using pottery discovered in an archaeological site close to the coast, dated to the Bronze Age (Zammit, 1928; Abela, 1999). As they have been interpreted as sites for the retting of flax, during their utilization they should have remained dry and the sea could not submerge them. This is the reason why these structures are not directly related to the sea level, as suggested by Biolchi et al. (2011), so they represent an upper limit.
Seismic velocity structures of Southern Italy from tomographic imaging of the Ionian slab and petrological inferences.
2012
International audience; In this study we have determined detailed Vp and Vs seismic velocity models of the Ionian lithosphere subducting beneath the Tyrrhenian basin and of the surrounding mantle, by applying a post-processing technique to a large sample of local earthquake tomography studies. Our seismic velocity models permit us to infer the presence of low velocity anomalies within the slab, which we interpret as regions that are partially hydrated by fluids released during the subduction process. A petrological interpretation of the velocity anomalies gives new details on the magmatism of the volcanic Aeolian arc. Furthermore our velocity models provide a more detailed description of th…
ABO genotyping by PCR-RFLP and cloning and sequencing
2005
A refined PCR-RFLP based method was established to genotype ABO blood groups. The main objective of this study was to make the techniques also suitable for working with degraded DNA. Specific primer design was carried out to choose fragments shorter than 200 bp as necessary in forensic and archaeological applications. Four fragments of exon 6 and 7 of the ABO gene were amplified and digested by in total 7 restriction endonucleases. Particular attention was paid to the base changes at nucleotide positions 261(delG), 297, 526, 703, 721, 771, 796 and 1060(delC) in order to distinguish the six common alleles A101, A201, B, O01, O02 and O03. Furthermore, this method also enables determination of…
Ornithological communities as indicators of recent transformations on a regional scale: the case of the Sicily island.
2014
A study on the Sicilian avifauna changes and its existing connections with the land use variations has been carried out from the 80s till today. We compared the Sicilian ornithological data acquired from the atlas maps with the regional land use maps data. We examined the land use variations and the distribution changes of some bird species on a regional level. To this aim, we analyzed the spatial distribution data of the birds in the period from 1984-1992 and 1993-2006. Moreover we examined the land use data of the period going from 1987-1988 and 1993-2000. After a preliminary analysis, we selected target species linked to different environments.
