No full textMethodology for Landslide Damage Assessment
No full textAbstractThis article focuses on an original methodology for landslide damage assessment of either masonry or reinforced concrete ordinary buildings at the urban scale. In the first step of the methodology, an analysis of the crack patterns is quickly performed for all the buildings by means of the Load Path Method [1]. The second step consists in the filling in of new survey damage forms and it ends with the creation of a landslide damage geotechnical chart of the region under study. This chart includes geomorphological data together with both the damage grade of the buildings and the direction of the possible settlements
Landslide damage assessment at the intermediate to small scale
No full textThis paper presents an original methodology that has been developed for the landslide damage assessment of either masonry or reinforced concrete ordinary buildings at the intermediate to small scale. After a brief introduction of the Load Path Method used for the analysis of the crack patterns, new survey damage forms are introduced. The forms are completed when a damage grade is assigned to each building within the region under study. Moreover, the analysis of the crack patterns makes it possible to select those buildings that are likely damaged by foundation settlements in order to create a landslide damage geotechnical chart. This chart includes the geomorphological map of the town under study, the damage grade of the buildings and the direction of the possible settlements. The application of the methodology to a territorial cell from the south of Italy is also reported

No full textSlow landslides in urbanised clayey slopes: An emblematic case from the south of Italy
No full textThe paper presents the emblematic case of the Pianello slope, that is a complex landslide basin located in the town centre of Bovino, one of the most beautiful villages in Italy. The low gradient slope is formed of highly tectonised and heterogeneous clays and it is affected by very slow and deep landsliding. The failure mechanisms are representative of many others not only in the Daunia area in the south of Italy, but also in the slopes of the Italian Apennines. The analysis resulted from field surveys, investigations and monitoring data as well as from the laboratory test results of the geotechnical investigation. The phenomenological interpretation of the landslide mechanism, along with the identification of the predisposing and triggering factors has been validated by both limit equilibrium and numerical analyses
Human T-lymphotropic virus type 1 (HTLV-1) prevalence and quantitative detection of DNA proviral load in individuals with indeterminate/positive serological results
No full textAbstract Background HTLV-1 infection is currently restricted to endemic areas. To define the prevalence of HTLV-1 infection in patients living in Italy, we first carried out a retrospective serological analysis in a group of people originating from African countries referred to our hospital from January 2003 to February 2005. We subsequently applied a real time PCR on peripheral blood mononuclear cells from subjects with positive or indeterminate serological results. Methods All the sera were first analysed by serological methods (ELISA and/or Western Blotting) and then the peripheral blood mononuclear cells from subjects with positive or inconclusive serological results were analyzed for the presence of proviral DNA by a sensitive SYBR Green real time PCR. In addition, twenty HTLV-I ELISA negative samples were assayed by real time PCR approach as negative controls. Results Serological results disclosed serum reactivity by ELISA (absorbance values equal or greater than the cut-off value) in 9 out of 3408 individuals attending the Sexually Transmitted Diseases Clinic and/or Oncology Department, and 2 out 534 blood donors enrolled as a control population. Irrespective of positive or inconclusive serological results, all these subjects were analyzed for the presence of proviral DNA in peripheral blood mononuclear cells by SYBR real time PCR. A clear-cut positive result for the presence of HTLV-1 DNA was obtained in two subjects from endemic areas. Conclusion SYBR real time PCR cut short inconclusive serological results. This rapid and inexpensive assay showed an excellent linear dynamic range, specificity and reproducibility readily revealing and quantifying the presence of virus in PBMCs. Our results highlight the need to monitor the presence of HTLV-1 in countries which have seen a large influx of immigrants in recent years. Epidemiological surveillance and correct diagnosis are recommended to verify the prevalence and incidence of a new undesirable phenomenon.</p
Evaluation of the Content of Minerals, B-Group Vitamins, Tocols, and Carotenoids in Raw and In-House Cooked Wild Edible Plants
No full textNotwithstanding the increased interest in wild edible plants, little is known on how some
domestic thermal processes can affect their content. The aim of this study was to investigate the
amounts of minerals, B1 and B2 vitamins, tocols, and carotenoids in raw, boiled, and steamed wild
edible plants, namely, Sonchus asper (L.) Hill s.l., Sonchus oleraceus L., Cichorium intybus L., and Beta
vulgaris L. var cicla. All vegetables were confirmed as high sources of lutein (from 6 to 9 mg/100 g)
and β-carotene (from 2 to 5 mg/100 g). Quite high amounts of violaxanthin and neoxanthin were
found. Alfa-tocopherol and γ-tocopherol were the main tocols, with same contents in raw and
processed vegetables (about 2.5 mg/100 g). The most abundant macro element and trace element
were, respectively, potassium and iron. B1 and B2 vitamins were found in low amounts in almost all
plants, with the exception of thiamine in Beta vulgaris (about 1.6 mg/100 g). Boiling led to a significant
loss of minerals (up to 60%) and B-group vitamins (up to 100%), while, among carotenoids, it only
affected violaxanthin levels (up to 90%). Steamed vegetables showed only a slight reduction, about
20%, in β-carotene and lutein, with a marked decrease in violaxanthin and neoxanthin. One hundred
grams of all fresh and cooked plants can be claimed as a source of vitamin A and E
