    Notes: The structural setting beneath the Ligurian Sea resuJts from several tectonic events reflected in the nature of the crust. The central-western sector, called the Ligurian basin, is part of the northwestern Mediterranean. It is a marginal basin that was generated in Oligocene-Miocene time by subduction of the Adriatic plate beneath the European plate and by the eastward drift of the Corsica-Sardinia block. The eastern sector belongs to the Tyrrhenian basin system and is characterized by extensional activity which since Tortonian time superimposed an earlier compressional regime. Our effort has been addressed in particular towards simplifying the complex nature of the crust of the Ligurian basin by modelling its genesis using uniform extension and sea-floor depth variation with age. In the rift stage of the basin's evolution, the initial subsidence reaches the isostatic equilibrium level of the asthenosphere by a thinning factor of 3.15. The additional passive process, corresponding to the cooling of the lithosphere since 21 Ma, leads to a total tectonic subsidence of 3.4 km, representing the boundary of the extended continental crust. For values up to 4.1 km a transitional-type crust is expected, whereas for higher tectonic subsidence values a typical oceanic crust should exist. After setting these constraints, the boundaries of the different crust types have been drawn based on total tectonic subsidence observations deduced from bathymetry and post-rift sediment thickness. Although there is a general agreement with the previous reconstructions deduced from other experimental data, the oceanic realm has wider extent and more complex shape. The northernmost part of this realm shows crust of sub-oceanic type altemating basement highs with lower subsidence values. The observed surface heat flux is consistent with the predicted geothermal held in the Alpine-Provençal continental margin and in the oceanic domain. However, a characteristic thermal asymmetry is clearly visible astride the basin, due to the enhanced heat flux of the Corsica margin. Even if the uniform extension model accounts well at a regional level for the present basement depth, a remarkable tectonic subsidence excess has been found in the Alpine-Provençal continental margin. This evidence agrees with the reprise in compression of the margin; the direction of the greatest principal stress is N120°E on average.

    Notes: We propose a thermo-mechanical model and a new interpretation of heat flux data for the Ligurian basin that may be a key to understanding the evolution of the NW Mediterranean. The model incorporates the removal of a portion of mantle lithosphere to explain the heat-flux and subsidence anomaly of the eastern (Corsican) margin of the basin. This process is envisaged as a result of eastward asthenosphere flow induced by the Apennines subduction system. After a heating phase, time-dependent conductive cooling and re-thickening of the lithosphere result in re-equilibrium of the thermal gradient to its initial value. Such a rifting mode can account for the asymmetric heat-flux and subsidence pattern observed across the basin and the present-day lithospheric thickness.

    Notes: Steady-state heat conduction modelling was carried out to calculate the crustal temperature field and thermal lithosphere thickness in the Baltic shield. The radiogenic sources at the surface were fixed depending on the age of the crust. Below the uppermost 10 kilometres, a relationship between heat generation and P-wave velocity was applied and seismic structure was used to define individual crustal blocks of specific thermal parameters. Small-scale surface heat-flow density anomalies are interpreted as lateral variations of heat generation within the upper part of the crust, whereas the large anomaly in the southern part of the shield is attributed to an anomalously high mantle heat-flow density. The results are shown on maps outlining mantle heat-flow density, Moho temperature and thermal lithosphere thickness. A relationship between subcrustal temperature and Moho depth was found, except for southern Sweden. The lithospheric thickness is found to exceed 200 km in the Bothnian Gulf–northern-central Finland and part of the Kola peninsula, where temperatures at the Moho are less than 500 °C; the temperature gradient at the top of the mantle has, on the average, a value of 7.5 mK m−1 and the mantle heat-flow density varies from 19 to 25 mW m−2. Towards the south, the lithospheric thickness decreases until it attains a value lower than 100 km under southern Sweden. In this latter area, the Moho temperature and mantle heat-flow density are remarkably high, 700°–900°C and 30–45 mW m−2, respectively, as well as the temperature gradient, which amounts to 10 mK m−1.

    Notes: Abstract A new frequency-magnitude relationship which takes into account the existence of an upper limit for the magnitude, and generalizes the previous ones, is proposed. The formula obtained has been applied to the Western Alps area activity during the period 1950–75, and in addition to the limiting magnitude value, some useful results for the calculation of the seismic risk have been deduced using Gumbel's theory. The use of the present relationship appears to be necessary when long periods of time are considered, while for the study of the annual probabilities the Gutenberg and Richter formula is shown to be sufficiently accurate.

    Description / Table of Contents: Zusammenfassung Es wurde die Globalstrahlung in GeU und GeMCap analysiert, womit es im Zusammenhang mit den thermo-pluviometrischen Angaben ermöglicht wurde, die klimatischen Charakteristiken eines am Meere gelegten Ortes (GeU) und eines auf den Appenninen gelegenen Ortes (GeMCap) zu beschreiben. Auf GeMCap weisen diese klimatischen Faktoren im Winter-Herbst einen kontinental-maritimen Charakter und im Frühling-Sommer einen streng kontinentalen Charakter auf.
    Notes: Summary It has been analysed the global solar radiation at GeU and GeMCap, that in connection with the thermo-pluviometric data has also allowed to outline the climatic characteristics of a coastal site (GeU) and of a site on Apennin ridge (GeMCap). At GeMCap these climatic parameters show a continental-maritime behaviour in winter-autumn and strictly continental feature in the remaining half year.

    Notes: Abstract We examined by light and electron microscopy study a Leeds-Keio ligament removed from a patient 6 years and 4 months after implant following rupture. The new ligament presented an outer capsule made up of bundles of collagen fibres running mainly perpendicular to the long axis of the ligament. Septa were seen emerging from the capsule and composed of bundles of collagen fibres surrounding the bundles of Dacron fibres. Each thread of Dacron was surrounded by a layer of connective tissue containing periodic acid-Schiff (PAS)-positive cells. The bundles of collagen fibres making up the outer capsule, the septa and the layer of connective tissue surrounding the Dacron threads were positive for anti-type I collagen antibody. The rehabitated Leeds-Keio ligament presented a specific organization at the septa zone, showing a layer of collagen fibrils alternating with a layer of cells. Our remodelling findings suggest a shoelace effect of the artificial ligament. On the other hand, the presence of type I collagen could be responsible for the good functional behaviour of this composite system. In conclusion, the factors that play an important role in determining this remodelling process and its mechanical function are unknown.

    Notes: Abstract The change in the air temperature recorded at the Genoa University observatory over 155 years followed the change in the wind direction. A warming occurred both from 1838 to 1869 and from 1890 to 1950. The latter warm period was followed by a cooling in the 1950s, when the lowest mean annual temperature occurred. Generally, a warm period corresponds to a growth in the southern components of the ground wind direction; the increase in the southerly circulation in the Mediterranean yields increased stability in dry weather. Temperature-depth data measured in a geothermal borehole reflect this climate change. A comparison between the measurements and a synthetic temperature profile, based on the air temperature history recorded at the observatory, indicates that the average temperature prior to the meteorological time series was about 0.6 K higher than the average of the decade 1973-1982.
