This book is one out of 8 IAEG XII Congress volumes, and deals with Landslide processes, including: field data and monitoring techniques, prediction and forecasting of landslide occurrence, regional landslide inventories and dating studies, modeling of slope instabilities and secondary hazards (e.g. impulse waves and landslide-induced tsunamis, landslide dam failures and breaching), hazard and risk assessment, earthquake and rainfall induced landslides, instabilities of volcanic edifices, remedial works and mitigation measures, development of innovative stabilization techniques and applicability to specific engineering geological conditions, use of geophysical techniques for landslide characterization and investigation of triggering mechanisms. Focuses is given to innovative techniques, well documented case studies in different environments, critical components of engineering geological and geotechnical investigations, hydrological and hydrogeological investigations, remote sensing and geophysical techniques, modeling of triggering, collapse, runout and landslide reactivation, geotechnical design and construction procedures in landslide zones, interaction of landslides with structures and infrastructures and possibility of domino effects. The Engineering Geology for Society and Territory volumes of the IAEG XII Congress held in Torino from September 15-19, 2014, analyze the dynamic role of engineering geology in our changing world and build on the four main themes of the congress: environment, processes, issues, and approaches.

BACKGROUND: Plasmodium falciparum MSP2 is a blood stage protein that is associated with protection against malaria. It was shown that the MSP2 dimorphic (D) and constant (C) regions were well recognized by immune human antibodies, and were characterized by major conserved epitopes in different endemic areas and age groups. These Abs recognized merozoite-derived proteins in WB and IFA. Here, the goal was to determine in mice the immunogenicity of the two allelic MSP2 D and C domains formulated with different adjuvants, for their possible use in future clinical studies. METHOD: Female A/J, C3H, and ICR mice were immunized subcutaneously 3 times at 3-week interval with a mixture of allelic and conserved MSP2 long synthetic peptides formulated with different adjuvants. One week after the third injection, sera from each group were obtained and stored at -20°C for subsequent testing. RESULTS: Both domains of the two MSP2 families are immunogenic and the fine specificity and intensity of the Ab responses are dependent on mouse strains and adjuvants. The major epitopes were restricted to the 20-mer peptide sequences comprising the last 8aa of D and first 12aa of C of the two allelic families and the first 20aa of the C region, this for most strains and adjuvants. Strong immune responses were associated with GLA-SE adjuvant and its combination with other TLR agonists (CpG or GDQ) compared to alhydrogel and Montanide. Further, the elicited Abs were also capable of recognizing Plasmodium-derived MSP2 and inhibiting parasite growth in ADCI. CONCLUSION: The data provide a valuable opportunity to evaluate in mice different adjuvant and antigen formulations of a candidate vaccine containing both MSP2 D and C fragments. The formulations with GLA-SE seem to be a promising option to be compared with the alhydrogel one in human clinical trials.

Epitheliocystis is an infectious disease affecting gills and skin of various freshwater and marine fishes, associated with high mortality and reduced growth of survivors. Candidatus Piscichlamydia salmonis and Clavochlamydia salmonicola have recently been identified as aetiological agents of epitheliocystis in Atlantic Salmon. In addition, several other members of the Chlamydiales order have been identified in other fish species. To clarify the pathogenicity of Chlamydia-like organisms towards fishes, we investigated the permissivity of two fish cell lines, EPC-175 (Fathead Minnow) and RTG-2 (rainbow trout) to three Chlamydia-related bacteria: Waddlia chondrophila, Parachlamydia acanthamoebae and Estrella lausannensis. Quantitative PCR and immunofluorescence demonstrated that W. chondrophila and, to a lesser extent, E. lausannensis were able to replicate in the two cell lines tested. Waddlia chondrophila multiplied rapidly in its host cell and a strong cytopathic effect was observed. During E. lausannensis infection, we observed a limited replication of the bacteria not followed by host cell lysis. Very limited replication of P. acanthamoebae was observed in both cell lines tested. Given its high infectivity and cytopathic effect towards fish cell lines, W. chondrophila represents the most interesting Chlamydia-related bacteria to be used to develop an in vivo model of epitheliocystis disease in fishes.

Aquesta és la primera guia d'identificació de la col∙lecció i es dedica als Efemeròpters (INSECTA: EPHEMEROPTERA). Els gèneres i grups d’espècies inclosos a la guia són aquells que de forma més freqüent hem trobat ens els estudis que realitzem en el marc del programa “Estudis de la Qualitat Ecològica dels Rius de la Província de Barcelona”. Aquest programa fou una iniciativa promoguda per la Diputació de Barcelona mitjançant la seva Oficina Tècnica d'Acció Territorial de l'Àrea de Territori i Sostenibilitat. La major part de les fotografies corresponen exemplars recol∙lectats el 2012 a les parts altes del riu Llobregat i els seus afluents pels membres del nostre grup de recerca, tot i que en alguns casos s’han examinat.

Honey produced by three stingless bee species (Melipona flavolineata, M. fasciculata and Apis mellifera) from different regions of the Amazon was analyzed by separating phenolic acids and flavonoids using the HPLC technique. Data were subjected to multivariate statistical analysis (PCA, HCA and DA). Results showed the three species of honey samples could be distinguished by phenolic composition. Antioxidant activity of the honeys was determined by studying the capacity of inhibiting radicals using DPPH assay. Honeys with higher phenolic compound contents had greater antioxidant capacity and darker color.

A tendência de algumas visões naturalistas de deduzir o sentido da ação humana da sua natureza biológica conduz a naturalizar a violência como fenômeno político inexorável. A violência naturalizada leva a sociedade para a dinâmica da inexorável violência, cuja única solução é a legitimação de uma violência total. Propomos, neste ensaio, a desconstrução crítica dos determinismos naturalistas por meio da análise da ação humana e da especificidade de sua potência que se manifesta como potência criadora (Cornelius Castoriadis) e potência do não (Giorgio Agamben). A potência da ação humana transcende os determinismos da sua natureza biológica, embora por eles esteja condicionada.
