Pausania e Roma (Nota di lettura a VIII 27, 1)

The paper suggests new argumets suppoting the integration of έπί τήζ between the words συμφοράυ and άρχής in Paus. VIII 27, 1. Therefore, the passage will lose the strong and explicit anti-roman charge it will have when we identify the συμφορά with Romans άρχή Still resisting are, however, the general reasons allowing us to evognize, in other statements and attitudes clearly represented in Periegesis, that Pausanias had a unpeaceful acceptance of Greeks´ subjection, and conflictual feelings about the new rulers

Notions of Computation and Monads

The i.-calculus is considered a useful mathematical tool in the study of programming languages, since programs can be identified with I-terms. However, if one goes further and uses bn-conversion to prove equivalence of programs, then a gross simplification is introduced (programs are identified with total functions from calues to values) that may jeopardise the applicability of theoretical results, In this paper we introduce calculi. based on a categorical semantics for computations, that provide a correct basis for proving equivalence of programs for a wide range of notions of computation

A new CH carbonaceous chondrite from Acfer, Algeria

A single stone weighing 1456 g was found in November 2002 in the Acfer area, Algeria. Oxygen isotope, chondrules-matrix ratio as well as other petrographic features point to a classification as CH carbonaceous chondrite

A new CO carbonaceous chondrite from Acfer, Algeria

Many small fragments, totally weighing 118 g were found in the Acfer area by an Italian dealer. Chondrules size and types (predominance of granular olivine type), occurrence of twinned clinoenstatite and absence of plagioclase suggested a classification as CO carbonaceous chondrite

A new CK carbonaceous chondrite from Hammada Al Hamra, Libya

A single stone weighing 198 g was found in 2001 in the Hammada al Hamra region of Libya. Petrographic features (mean chondrules dimensions, coarse grained matrix and presence of AOIs and CAIs) point to a classification as CK carbonaceous chondrite

Study of soft QCD at the Tevatron

Measurements of particle production and inclusive differential crosssections in inelastic pp collisions are reported together with studies of the underlying event in various event topologies. A comparison with Monte Carlo model predictions at the hadron level is performed. The aim is to provide data that can be used to improve QCD models of minimum-bias production and of the underlying event
