Utopiju un antiutopiju iezīmes Luisas Lorijas Romānā “Devējs”
2016
Pašreizējais darbs ir veltīts Luisas Lorijas romāna Devējs analīzei. Pētījuma mērķis ir uzzināt kāda ir literāro utopiju un antiutopiju izcelsme un to attīstība, kādas raksturīgās iezīmes ir atrodamas ievērojamu utopiju un antiutopiju autoru darbos, un, lai atklātu kuras iezīmes Lorijas darbam ir kopīgas ar Tomasa Mora, Tommazo Kampanellas un citu utopiju un antiutopiju autoru darbiem. Pētījumā tiek izmantotas satura analīzes, uzmanīga lasījuma, un interpretācijas metodes. Galvenie rezultāti parāda, ka ideja par utopisku vietu pastāv jau vairākus gadsimtus, un, ka antiutopiskā literatūra parādījās kā atbilde uz cilvēces neveiksmīgajiem mēģinājumiem radīt reālas utopiskas kopienas. Tika izda…
A smart and operator independent system to delineate tumours in Positron Emission Tomography scans
2018
Abstract Positron Emission Tomography (PET) imaging has an enormous potential to improve radiation therapy treatment planning offering complementary functional information with respect to other anatomical imaging approaches. The aim of this study is to develop an operator independent, reliable, and clinically feasible system for biological tumour volume delineation from PET images. Under this design hypothesis, we combine several known approaches in an original way to deploy a system with a high level of automation. The proposed system automatically identifies the optimal region of interest around the tumour and performs a slice-by-slice marching local active contour segmentation. It automa…
Upon oxidative stress, the antiapoptotic Hsp60/procaspase-3 complex persists in mucoepidermoid carcinoma cells.
2008
Hsp60, a mitochondrial chaperonin highly conserved during evolution, has been found elevated in the cytosol of cancer cells, both in vivo and in vitro, but its role in determining apoptosis during oxidative stress (OS) has not yet been fully elucidated. The aim of the present work was to study the effects of OS on Hsp60 levels and its interactions with procaspase- 3 (p-C3) and p53 in tumor cells. NCI-H292 (mucoepidermoid carcinoma) cells were exposed to various concentrations of hydrogen peroxide (H2O2) for 24 hours. Cell viability was determined by Trypan blue and MTT assays. DNA damage was assessed by the Comet assay, and apoptosis was measured by the AnnexinV cytofluorimetric test. Expos…

Infrastructura Naturans. Architetture di trasformazione della circonvallazione di Palermo
2022
The article discusses the theoretical system that supports design themes and processes of recycling large urban road infrastructures, referring to an international research that frames them among the sustainable regeneration processes of the contemporary city, and further evoking the project for the transformation of Palermo's ring road that has been elaborated within this research. Witnesses of past urban seasons, these infrastructures are marked by a peculiar morphology that deserves to be maintained, while they must emancipate themselves from asphalt and adapt to new urban mobilities. By hybridizing vegetation and buildings as never before, the longest roadways in our urban contexts may …

Gravi malformazioni in melanzana in Sicilia associate alla presenza di fitoplasmi
2010
Stunting and leaf malformation were repeatedly observed during vegetative growth in eggplant cultivations located in Sicily (Ragusa). Symptoms appear during first weeks after transplantation, and modify normal shape of plants as well as decrease their production, in several cases stunting was present but only in half of the plant. The disease was scattered distributed in the fields and with percentages below 10%. Samples were collected from symptomatic and asymptomatic plants, and shoots and midribs were used for nucleic acid exstraction to verify possible phytoplasma presence and identity. Nested PCR assays with primers P1/P7 followed by R16mF1/R16mR1 (Gundersen and Lee, 1996) allow to obt…
Screening of lactic acid bacteria for reducing power using a tetrazolium salt reduction method on milk agar.
2013
WOS:000315703100020 ; www.elsevier.com/locate/jbiosc; International audience; Reducing activity is a physiological property of lactic acid bacteria (LAB) of technological importance. We developed a solid medium with tetrazolium dyes enabling weakly and strongly reducing LAB to be discriminated. It was used to quantify populations in a mixed culture (spreading method) and screen strains (spot method).
SURFACE AND MECHANISTIC PROPERTIES OF RECYCLED BITUMINOUS MIXTURES
2019
EXECUTIVE SUMMARY Problem Often, when the characteristics of a bituminous mixture are analised, there are major differences between in-lab and in-situ results. This is due to the fact that the procedures and techniques implemented during the design phase (in lab) may be different from those used on site. Then, is very important to be able to predict the main properties of a mixture particularly when innovative materials are used. For example, when crumb rubber is used, phisical and volumetric properties of mixes may change over time, in particular due to the swelling phenomenon that it alters different properties of the mixture (e.g., viscosity). This study aims to investigate the main aspe…
