Museo Geologico “Gaetano Giorgio Gemmellaro”

The Museum's patrimony consists of over 600.000 fossils divided into numerous collections. You can stand out some collections about Geological history of Sicily with fossils that span a time interval of over 270 million years and geological and paleontological collections from all over the world. The museum holds over a thousand holotypes (unique specimens on which the fossil species have been established). The exhibition area is divided into three floors. Among the exhibits you can appreciate a gypsum crystal containing a drop of water from the Mediterranean of 6 million years ago and the oldest human skeleton of Homo sapiens found in Sicily dated Upper Paleolithic.

Nature of Bonding in Group 13 Dimetallenes: a Delicate Balance between Singlet Diradical Character and Closed Shell Interactions

2010

The nature of metal−metal bonding in group 13 dimetallenes REER (E = Al, Ga, In, Tl; R = H, Me, tBu, Ph) was investigated by use of quantum chemical methods that include HF, second order Møller−Plesset perturbation theory (MP2), coupled cluster (CCSD(T)), complete active space with (CASPT2) and without (CAS) second order perturbation theory, and two density functionals, namely, B3LYP and M06-2X. The results show that the metal−metal interaction in group 13 dimetallenes stems almost exclusively from static and dynamic electron correlation effects: both dialuminenes and digallenes have an important singlet diradical component in their wave function, whereas the bonding in the heavier diindene…

Oratory of the Falegnami

This precious chapel, incorporated in the Convent of the Teatini, former headquarter of the University of Palermo in via Maqueda, is the reconstruction of the oratory destroyed during the realization of the portico, in the main building. Closed to the public and to worship for many years, it was reopened as University Chapel in 2009.

Politisko reklāmu ietekme uz vēlētāju ar dažādu zināšanu līmeni par politiku izvēli

2013

Bakalaura darba „Politisko reklāmu ietekme uz vēlētāju ar dažādu zināšanu līmeni par politiku izvēli” pētījuma mērķis bija izpētīt, vai politiskās reklāmas vairāk ietekmē to vēlētāju izvēli, kam ir zemāks zināšanu līmenis par politiku. Tika izvirzīta hipotēze: politiskās reklāmas vairāk ietekmē tos vēlētājus, kam ir zemāks zināšanu līmenis par politiku. Tika veikts eksperiments, par izlasi ņemot 60 Latvijas Universitātes studentus. Eksperimenta gaitā tika izmantotas 3 politiskās reklāmas un bakalaura darba autores izveidotās anketas, kurās tika noskaidrots dalībnieku zināšanu līmenis par politiku, kā arī viedoklis par politiskajām partijām. Pētījuma mērķis tika izpildīts un hipotēze daļēji …

Research Group in Reproductive Medicine

The mission of the Reproductive Medicine research group is to advance the understanding of processes associated with human reproduction for translational application, improving the efficiency of assisted reproductive treatments and maternal-fetal health. They follow a particular approach in the fields of regenerative medicine related to the endometrium and genomic studies on embryonic viability and endometrial receptivity, as well as other factors that cause infertility.

2017

It has been shown in previous papers that classes of (minimal asymmetric) informationally-complete positive operator valued measures (IC-POVMs) in dimension d can be built using the multiparticle Pauli group acting on appropriate fiducial states. The latter states may also be derived starting from the Poincare upper half-plane model H . To do this, one translates the congruence (or non-congruence) subgroups of index d of the modular group into groups of permutation gates, some of the eigenstates of which are the sought fiducials. The structure of some IC-POVMs is found to be intimately related to the Kochen-Specker theorem.

Variant GII.4 noroviruses in Italian children

2009

Objectives: Among human noroviruses (NoVs), a few genogroup II strains of genotype 4 (GII.4) are dominant worldwide. GII.4 NoVs evolve rapidly and in 2006 two new epidemic variants have been identified. To investigate the circulation of GII.4 NoV variants in Italy a sequence analysis was performed on NoV strains obtained from children hospitalized for sporadic viral gastroenteritis in Palermo. Methods: A total of 465 faecal specimens were collected from children (< 5 years) hospitalized from January 2005 to December 2006. The presence of NoVs was detected by RT-PCR using primers JV12/JV13, targeting the region A of the RNA-dependent RNA-polymerase (RdRp) gene. NoV strains were genotyped by …

Economic Digital Transformation Lab

The main aim of the group is tracing the determinants of economies’ digitalization processes within countries in the field of economics, finance and law, by sharing experiences of different European countries of processes of economies’ digitalization. An extremely important point are the legal aspects which keep up economic changes and are well adapted to changes in economies or, by contrast, leave some areas of economic life underregulated. Another objective is the modelling of perspectives of business development: how it should be redefined according to organisational structures and ecological aspects, or how digital changes on the labour market determine the development trends of busines…

Transitory disappearance of microglia during the regeneration of the lizard medial cortex

1994

In normal lizards, microglial cells populate the medial cortex (a zone homologous to the hippocampal fascia dentata), with a preferential distribution along the border between the granular cell layer and the plexiform layers. Intraperitoneal injection of the neurotoxin 3-acetylpyridine (3AP) induces a selective lesion in the medial cortex with a rapid degeneration of the granular layer and its zinc-enriched axonal projection. Within 6-8 weeks, the granular layer is, however, re- populated by a new set of neurons generated in the subjacent ependyma and the cell debris is removed. The aim of this study was to determine to what extent microglia were involved in the scavenging processes during …

In the "Sala Gerbasi” (also called “Sala delle Capriate”) at the Steri has been set up the new picture gallery of the University, thanks to the “Grande Abatellis” Project within the Valorization Agreement, which aims to make available part of the collections in the deposits of the Regional Gallery of Palazzo Abatellis.

Copper transporter COPT5 participates in the crosstalk between vacuolar copper and iron pools mobilisation

2019

Copper (Cu) deficiency affects iron (Fe) homeostasis in several plant processes, including the increased Fe requirements due to cuproprotein substitutions for the corresponding Fe counterpart. Loss-of-function mutants from Arabidopsis thaliana high affinity copper transporter COPT5 and Fe transporters NATURAL RESISTANCE-ASSOCIATED MACROPHAGE PROTEIN 3/4 (NRAMP3 and NRAMP4) were used to study the interaction between metals internal pools. A physiological characterisation showed that the copt5 mutant is sensitive to Fe deficiency, and that nramp3nramp4 mutant growth was severely affected under limiting Cu. By a transcriptomic analysis, we observed that NRAMP4 expression was highly induced in …
