Slow-moving landslides are widespread in the Mediterranean area， causing damage to the exposed facilities and economic losses in many countries. The recognition of slow-moving landslides in urban areas is always a difficult task to deal with because the presence of buildings， infrastructures， and human activities usually conceals the morphological signs of these landslide activities. So， in the last decades， numerous researchers have shown new methodologies to deepen the studies of similar instability phenomena. The present research is based on an integrated approach to investigate the landslide boundaries， type of movement， failure surface depth， and vulnerability state of buildings in Rota Greca village (Calabria region， southern Italy) affected by a slow-moving landslide. For this purpose， multi-source data were acquired through geological and geomorphological surveys， recognition of landslide-induced damage on the built environment， subsurface investigations (e.g.， continuous drill boreholes， Standard Penetration Test， Rock Quality Designation index and inclinometer monitoring)， laboratory tests (direct shear tests on undisturbed samples)， geophysical survey， and InSAR-derived map of deformation rates. The complete integration of multi-source data allowed for the construction of reliable landslide modelling with relative geotechnical properties. In addition， the cross-comparison between surface deformation data by SAR images and severity damage level collected on the exposed buildings enabled to obtain the vulnerability map of the built area. In particular， the achieved goals highlighted two failure surfaces at about -13 and -25 m depth， causing a high vulnerability value for the buildings allocated in the central portion of the Rota Greca village. The knowledge acquired by the multi-approach can be used to manage and implement appropriate landslide risk mitigation strategies， providing helpful advice and best practices to state-run organisations and stakeholder

Seven Cornulites species, including a new one—Cornulites leonei n. sp., are described from the Upper Ordovician Portixeddu Formation(Katian, stage slices Ka2-3) of Sardinia and the Cavá(lower Katian,stage slice Ka2) and Estana(upper Katian, stage slices Ka3-4) formations of the Pyrenees. The Sardinian and Pyrenean cornulitids represent an adaptation to live in environments with high sedimentation rates and limited hard substrates availability. Their prominent annuli could have had a stabilizing function in the soft sediment that helped cornulitids to keep a favourable position in the sediment to enable suspension feeding. The known Late Ordovician cornulitid diversity in different Gondwana areas is low, usually ranging from one to three taxa, being higher(seven) in Sardinia. Like other benthic groups during the Late Ordovician, the cornulitid tubeworm faunas within the high-latitude peri-Gondwana Province indicate a certain endemism and share morphological and ecological affinities, such as a small body size and tubes with a strikingly small apical angle. Although essentially endemic, some links with cornulitids from the Late Ordovician of Scotland are revealed.

In this paper, we analyze the enthalpy, enthalpy energy density, thermodynamic volume, and the equation of state of a modified white hole. We obtain new possible mathematical connections with some sectors of Number Theory, Ramanujan Recurring Numbers, DN Constant and String Theory, that enable us to extract the quantum geometrical properties of these thermodynamic equations and the implication to the quantum vacuum spacetime geometry of our early universe as they act as the constraints to the nature of quantum gravity of the universe.

Is maturity index an efficient tool to assess the effects of the physical disturbance on the marine nematode assemblages?—A critical interpretation of disturbance-induced maturity successions in some study cases in Maldives

引用

Acta Oceanologica Sinica 2016年第4期35卷 89-98页

作者： SEMPRUCCI F. COLANTONI P. BALSAMO M. dipartimento di scienze Biomolecolari (diSB) Università di Urbino

Maturity index（MI）, based on nematode life strategies, has been proposed in 1990 to assess the possible variations of the terrestrial and freshwater nematode assemblages induced by anthropogenic activities. It was subsequently applied also to marine ecosystems and, even if comparatively not yet very popular, it offers a good method to assess the ecological quality in relation to a wide range of anthropogenic drivers. However, few data are available on its response to physical stress, a key factor especially in the coastal areas. In this study, marine nematode genera from two study cases carried out in Maldives are used to test both MI and life strategy traits（i.e.,c-p classes） for detecting the effects of physical disturbance. The results confirm that nematodes are well adapted to physical stress showing a general high rate of recovery. C-p scaling and MI did not seem to be appropriate for revealing this disturbance type probably because there are no empirical evidences on the life strategy of several genera, and a possible differential response to various disturbance types may be hypothesized.
