ZACentrale: il nuovo laboratorio di arti e idee della Fondazione Merz
2021
L'articolo prende in esame la collaborazione tra la Fondazione Merz di Torino e il Comune di Palermo attraverso la ricognizione delle attività di ZACentrale presso i Cantieri Culturali alla Zisa di Palermo con particolare riferimento al progetto espositivo "L'altro, lo stesso" a cura di Beatrice Merz ed Agata Polizzi. Il contributo presenta le opere in mostra di Lawrence Weiner, Rosa Barba, Lida Abdul, Mario Merz, Marisa Merz e Alfredo Jaar.
A survey of the function of the lethal kettle traps of Arisaema (Araceae), with records of pollinating fungus gnats from Nepal
2000
Abstract Evidence from recent research combined with an evaluation of the literature indicates that Arisaema is adapted to pollination by fungus gnats. It apparently shares this peculiarity among aroids only with the distantly related genus Arisarum . In addition to previous records from Japan and North America, systematic collections from nine Arisaema species during several expeditions in the Himalayas in Nepal showed that, although other less efficient insect groups may participate, the nematoceran families Mycetophilidae and Sciaridae are the principal pollen vectors; they best fit the pollination apparatus of the mainly (para)dioecious kettle trap blossoms. A total of 16 fungus gnat ge…
Les squelettes : structures d'interaction directe et intuitive avec des formes 3D
2014
The interactions in shape creation graphic applications are far from natural. The user tends to avoid as much as possible such applications and prefer to sketch or model his/her shape.To bridge this widening gap between computer and the general public, we focus on skeletons. They are intuitive shape representation models that we propose to use as direct and intuitive interaction structures.All skeletons suffer from very low quality as shape representation models, concerning the geometry of the shape they capture, the quantity of skeletal noise they contain or the lack of useful organization of their elements. Moreover, some functionalities that must be granted to skeletons are only partiall…
Study of optical and magneto processes in Rb atomic vapor layer of nanometric thickness
2012
Using a narrow-band resonant fluorescence spectra from a nano-cell with a thickness of L= [lambda]/2, and VSOP resonances formed at a thickness L =[lambda] ([lambda] is the wavelength of the resonant radiation), for the first time it was experimentally investigated the behaviour of the frequency and intensity (transition probabilities) of the atomic hyperfine structure transitions between the 85Rb, 87Rb, D1 and D2 lines Zeeman sublevels in external magnetic fields in range 5 - 7000G. The behaviour of tens of previously unstudied atomic transitions was analyzed and it is demonstrated that the intensities of these lines can both greatly increase, and decrease (tenfold). For the first time it …
Achieving universal primary education by 2015 - a chance for every child
2003
03046http://www-wds.worldbank.org/servlet/WDSContentServer/WDSP/IB/2003/09/06/000094946_03082204005065/Rendered/PDF/multi0page.pdf; A number of countries committed themselves to the Millennium Development Goals (MDGs), aimed at eradicating extreme poverty, and improving the welfare of people by the year 2015. The book assesses whether universal primary education can be achieved by 2015. The study focuses on the largest low-income countries that are furthest from the goal, home to about seventy five percent of the children out of school globally. By analyzing education policies, and financing patterns in relatively high-performing countries, the study identifies a new policy, and financing f…

Alignement moléculaire : caractérisation et application à la mesure de thermalisation ultra-rapide et au contrôle de génération d'harmoniques
2013
The thematic of this thesis is molecular alignment. The latter is a very important topic that opens the way toward a much more thin control of many phenomenons. So, we have developed a new measurement technique of the molecular alignment along one axis that permits to preserve the sign of alignment. This one is, like other measurement techniques developed by the team,based on the measurement of the refractive index variation induced by the molecular alignment.The technique developed then also permits the molecular alignment measurement, being also an application of it because it allows the third harmonic generation. In the last study, molecular alignment is implemented to show that it bring…
Journalistic practices of science popularization in the context of users’ agenda: A case study of „New Scientist”
2017
The article includes a discussion of two models which describe contemporary communication processes in journalism: agenda-setting and news value, indicating the need to expand their research tools to include qualitative methods, and merging the analyses of the reception and the message. It also includes indications as to the possibility, or even the social relevance, of the methods for applying those research perspectives to analysing journalism popularising science. Later, I present the results of an analysis of the content of a sample of 500 most read popular science texts available on the New Scientist website. I demonstrate which thematic areas were valued by the readers, and what value…
