Comparative histological and immunohistochemical study of ameloblastomas and ameloblastic carcinomas
2017
Background This study aimed to compare the histological and immunohistochemical characteristics of ameloblastomas (AM) and ameloblastic carcinomas (AC). Material and Methods Fifteen cases of AM and 9 AC were submitted to hematoxilin and eosin (H&E) and immunohistochemical analysis with the following antibodies: cytokeratins 5,7,8,14 and 19, Ki-67, p53, p63 and the cellular adhesion molecules CD138 (Syndecan-1), E-cadherin and β-catenin. The mean score of the expression of Ki-67 and p53 labelling index (LIs) were compared between the groups using the t test. A value of p<0.05 was considered to be statistically significant. Results All cases were positive for CKs 5, 14 and 19, but negative fo…
In-depth characterization of denitrifier communities across different soil ecosystems in the tundra
2022
Abstract Background In contrast to earlier assumptions, there is now mounting evidence for the role of tundra soils as important sources of the greenhouse gas nitrous oxide (N2O). However, the microorganisms involved in the cycling of N2O in this system remain largely uncharacterized. Since tundra soils are variable sources and sinks of N2O, we aimed at investigating differences in community structure across different soil ecosystems in the tundra. Results We analysed 1.4 Tb of metagenomic data from soils in northern Finland covering a range of ecosystems from dry upland soils to water-logged fens and obtained 796 manually binned and curated metagenome-assembled genomes (MAGs). We then sear…

Roles of Exogenous Technologies in Vehicle Innovation: Cases from a Japan’s Automotive Parts Manufacturing Firm
2017
This paper explores the roles of technological innovations in the growth of Japan’s motor vehicle industry, mainly from technology spillover perspective from the early 2000s to today. An empirical analysis focusing on business performances, R&D investments, and patent applications taking a noteworthy unique case in Japan was attempted. Empirical analyses on the productivity of patent to technology stock, use of exogenous technologies for their own technological innovation on its Automotive Business Unit elucidated that innovation capabilities, incorporation of exogenous technologies, and profit generation makes a virtuous cycle of continuous technological innovation. Furthermore, we fou…

Oded Ezer, Il mirabolante costruttore di lettere e alfabeti
2008
Tutte le altezze, profondità e larghezze delle cose tangibili e naturali: paesaggi, tramonti, il profumo del fieno, il ronzio delle api, la bellezza che dipende dalle ciglia, ma è erroneamente attribuita agli occhi; tutte le incommensurabili emozioni e tutti i moti dell'animo umano, che paiono senza limiti; cose e pensieri orrendi, terribili e misteriosi, ma anche belli; tutto questo è compreso, contenuto e ordinato in un piccolo guazzabuglio di lettere. Ventisei simboli! Così scriveva nel 1923 Francis Maynell, il tipografo inglese che aveva conquistato il mondo con ventisei soldati di piombo, i quali altri non erano che i caratteri dell'alfabeto necessari alla produzione della Nonesuch Pre…
Inexhaustible creator of letters and alphabets
2009
It really is a shame that the only way to be truly amazed by things that jump off the flat page, or twist and turn, fold, swell up, or create incredible pop-up buildings is to leaf through the pages of children's books, following the adventures of their heroes as they make their way through the fragments of landscapes they are called on to cross, through forests and valleys, in and out of tiny houses, castles and ravines, past dinosaurs and dragons, through ocean beds with octopuses and sperm whales, imaginary spaces. The shapes of the heroes of these tales rise up from the pages of the books they dwell in, like the memory of some unpunished crime, as if they too feel the same strong sense …
Una sola moltitudine
2019
Una sola moltitudine, così venne intitolata una raccolta di scritti del portoghese Fernando Pessoa, adoperando una definizione che è un ossimoro e ben si addice a un progetto complesso come One of a type. Attraverso la costruzione di un alfabeto, e quindi con l’unicità di una famiglia di glifi e la molteplicità delle loro forme, viene disegnata l’identità visiva della città di Palermo, contemporanea e profondamente antica, desiderosa di futuro e stratificata nel tempo. Non è più bastevole un solo segno per comunicare l’identità della città e del territorio a cui si riferisce. Può però forse esserlo un sistema complesso come quello definito da un alfabeto, che si presta a essere adoperato, f…
Sisäistyneet ristiriidat, tunnetyö ja tietotyöläissubjektiviteetin rakentuminen
2015
Yliopistotyö on esimerkki uuden työn muodoista, joissa työ kiinnittyy aiempaa vahvemmin yksilöön. Samalla vastuu työelämän vaatimuksiin yltämisestä siirtyy työntekijälle itselleen. Työyhteisön ristiriitatilanteissa organisaation ongelmat sisäistyvät työntekijän yksityisiksi ja tunne-elämän ongelmiksi.
Ultra-High Energy Neutrinos at the Pierre Auger Observatory
2013
The observation of ultrahigh energy neutrinos (UHE nu s) has become a priority in experimental astroparticle physics. UHE nu s can be detected with a variety of techniques. In particular, neutrinos can interact in the atmosphere (downward-going nu) or in the Earth crust (Earth-skimming nu), producing air showers that can be observed with arrays of detectors at the ground. With the surface detector array of the Pierre Auger Observatory we can detect these types of cascades. The distinguishing signature for neutrino events is the presence of very inclined showers produced close to the ground (i.e., after having traversed a large amount of atmosphere). In this work we review the procedure and …
