Da retta a curva: costruzioni grafiche di trasformazione di una retta spezzata in una linea curva
Disegnare con, 2012 Proviamo a pensare quali sequenze di tratti curvilinei possono meglio descrivere una poligonale. Le curve più semplici sono la circonferenza e l’ellisse, e queste sono le due linee curve che vengono utilizzate in questo saggio.

Holocene shoreline displacement at Agardhbukta, eastern Spitsbergen, Svalbard [PDF]
, 1991 An emergence curve based on nine radiocarbon dated samples of mosses, shells, whale bones and driftwood has been constructed for Agardhbukta. Beach sediments and delta deposits were found up to c.

A contribution to the understanding of percolation phenomena in binary liquids [PDF]
, 2004 In the present work it was shown the important role of the Ei/E parameter in the characterization of polar liquids. It could be demonstrated that the application of the broad range dielectric spectroscopy together with the analysis of the quasi-static ...

Occurrence of pumice on raised beaches and Holocene shoreline displacement in the inner Isfjorden area, Svalbard [PDF]
, 1984 Finds of pumice on raised beaches in the inner Isfjorden area are reported. Pumice is abundant in two zones, and four levels can be distinguished in some areas. The highest lying level has the greatest concentration of pumice and is dated to a maximum of

On polar relative normalizations of ruled surfaces
Universal Journal of Mathematics and Applications, 2018 This paper deals with skew ruled surfaces in the Euclidean space $\mathbb{E}^{3}$ which are equipped with polar normalizations, that is, relative normalizations such that the relative normal at each point of the ruled surface lies on the corresponding ...

Polar transform and local positivity for curves [PDF]
Annales de la Faculté des sciences de Toulouse : Mathématiques, 2020 Using the duality of positive cones, we show that applying the polar transform from convex analysis to local positivity invariants for divisors gives interesting and new local positivity invariants for curves. These new invariants have nice properties similar to those for divisors.

Topological invariants of plane curve singularities: Polar quotients and Lojasiewicz gradient exponents [PDF]
, 2019 In this paper, we study polar quotients and Łojasiewicz exponents of plane curve singularities, which are not necessarily reduced. We first show that, for complex plane curve singularities, the set of polar quotients is a topological invariant.

Prey composition and feeding rate of Sagitta elegans var. arctica (chaetognatha) in the Barents Sea in early summer [PDF]
, 1991 Sagitta elegans var. arctica, the dominant and locally abundant chaetognath in the Barents sea, was collected from the upper 50 m in Arctic water masses during an ice edge bloom in early summer 1983. In situ sampling was made along a transect at discrete
