The increasingly wider application of lime‐based materials for the conservation and restoration of historical buildings has led to a revival of interest in lime putty. One of the most well‐known and highly regarded properties of lime putty is its plasticity/workability. This paper describes the results of a rheological investigation conducted on putties having identical water content but aged for different times, with the aim of providing an objective and quantitative evaluation of plasticity. Rheological measurements have demonstrated that, all other conditions being equal, shear stress increases with aging. We propose here to consider some parameters derived from Tattersall and Bingham models that can be used as a quantitative measure of plasticity directly correlated with aging.

The salient points of Relativistic Extended Thermodynamics (R.E.T.) are here revised according to the Lagrangian view-point: Attention is focused to each material particle and to its physical properties, during all the motion of the same particle. The results for the non relativistic case are already present in literature. Here a similar procedure is followed for R.E.T. with an arbitrary number of moments. It is also shown how the Einstenian Relativity Principle and some symmetry condition, which are present in the Eulerian view-point, can be "translated" in the Lagrangian view-point, where they are no more so self-evident

The banding pattern of polytene chromosomes of Anopheles atroparvus has previously been studied and described by FRIZZI (1947a-b). Further studies carried out to date on characteristics of the maculipennis group, as far as the numeration of the chromosomes and of the zones, and their extension are concerned, have been based on the original codification of FRIZZI, which has been found entirely satisfactory for the study of the various chromosomal aberrations. Some zones however, especially those found in larvae approaching nymphosis, permit the observation of more detailed structures. These structures have been examined and described, always adhering to the original codification of FRIZZI as far as the numeration and the limits of the chromosomal sections are concerned. A detailed description of the banding pattern is necessary today in order to further studies on the topographic relationships, within the chromosomes themselves, between their different replicative entities, and between the structures of the chromosomes of the sibling species of the group. In this work autoradiographic labelling with TD-HS has been used to evidence DNA synthesis in the zones or regions which present more developed puff -like structure and to ascertain the presence of DNA in the nucleolar region. The species has been classified as A . atroparvus instead of A . maculipennis atroparvus, on the basis of the new status of the maculipennis group (STONE 1970) which agrees with the distinct separation, in nature, of the species A.atroparvus, from the other species of the group, and in particular from A . labranchiae. This separation has been evidenced on a zoogeographical, an ethological and recently on a genetic basis (BIANCHI 1968). STONE,A., 1970: A synoptic catalog of the mosquitoes of the World.
