Prefazione a Messina, R., "La strage negata"
No full text"Il 19 ottobre del 1944 si consumò a Palermo uno degli eventi più drammatici dell'immediato dopoguerra: truppe dell'esercito italiano aprirono il fuoco su centinaia di cittadini che, al grido di 'pane, pasta e lavoro!', sfilavano per il centro della città in una pacifica protesta contro il carovita. 24 tra i manifestanti, e tra di loro bambini e ragazzi, rimasero uccisi; 156 furono feriti. [...] Ripercorrendo tutte le tappe dell'iter giudiziario dell'eccidio del 19 ottobre, e concentrandosi in particolare sull'analisi del processo svoltosi presso il tribunale militare di Taranto nel febbraio del 1947, Rino Messina ci dimostra come dietro il paravento della "tutela dell'ordine pubblico" si nascose in realtà la precisa volontà politica di proteggere le forze armate in un momento particolarmente critico quale fu quello attraversato dall'Italia nella transizione dal fascismo alla Repubblica, e in particolare dalla Sicilia, percorsa anche da istanze indipendentiste.
Winter cold tollerance of kiwifruit. A survey after winter frost injury in Northern Italy
No full textQuantitative flowering of kiwifruit
(Actinidia deliciosa (A. Chev.) C. F. Liang et A.
R. Ferguson var. deliciosa) was investigated in 25
North Italian kiwifruit orchards to evaluate frost
resistance following a severe cold spell in January
1985, when air temperatures dropped as low as
- 23 ° C. The percentage of fruitful shoots in female
cultivar 'Hayward' began to decrease at -11°C;
at about -18°C very few reproductive buds burst
the following spring. As temperatures decreased,
the proportion of vegetative shoots, arising from
meristems in the basal axils of winter buds,
increased. The male cultivar, 'Matua' reacted in a
similar way to 'Hayward', but 'Matua' was more
tolerant to frost injury. The same reduction in
flowering shoots, resulting from a fall in
temperature, was obtained at about - 1.2 to
-1.8 °C lower in male than in female plants in the
range from -II to -18°C. In no case was plant
death observed. Acutely damaged plants were
capable of regrowth from adventitious buds either
of the leaders or of the trunk

Turbulence modulation in particle laden pipe flow: Exact regularized point particle method
No full textMany technological applications are characterized by turbulent bounded flows with dispersed particles. For high mass load (particle/fluid mass ratio) a significant inter-phase momentum exchange occurs (two-way coupling regime), inducing a significant alteration of the turbulent field which, in turn, modifies the dynamics of the suspended phase. Aim of the present study is exploring the potentially of recently developed momentum coupling method, dubbed the Exact Regularized Point Particle (ERPP) method, in reproducing via Direct Numerical Simulation (DNS) the detailed dynamics of a particles laden turbulent pipe flow. The comparison with available experimental and numerical data confirms the ability of the new approach in reproducing the relevant dynamics also in parameter ranges which are unaccessible to standard techniques
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Casimir-Polder force density between an atom and a conducting wall
No full textIn this paper we calculate the Casimir-Polder force density (force per unit area acting on the elements of the surface) on a metallic plate placed in front of a neutral atom. To obtain the force density we use the quantum operator associated to the electromagnetic stress tensor. We explicitly show that the integral of this force density over the plate reproduces the total force acting on the plate. This shows that, although the total force is obtained as a sum of surface element-atom contributions, many-body components proportional to the atomic polarizability are included in our result. The local force that we obtain can also be useful in evaluating Casimir torques or stresses on the wall
Editorial. Still searching for the origin of migraine. From comorbidities to chronicization
Full text linkMigraine is amultifactorial disorder with huge ramifications in the central nervous system. Despite
the enormous progress made in recent years in understanding the pathophysiological mechanisms
underlying this painful condition, little is known about the factors behind the evolution from the
episodic to the chronic form of migrain
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
