Advances in surfaces and osseointegration in implantology. Biomimetic surfaces
2015
The present work is a revision of the processes occurring in osseointegration of titanium dental implants according to different types of surfaces -namely, polished surfaces, rough surfaces obtained from subtraction methods, as well as the new hydroxyapatite biomimetic surfaces obtained from thermochemical processes. Hydroxyapatite’s high plasma-projection temperatures have proven to prevent the formation of crystalline apatite on the titanium dental implant, but lead to the formation of amorphous calcium phosphate (i.e., with no crystal structure) instead. This layer produce some osseointegration yet the calcium phosphate layer will eventually dissolve and leave a gap between the bone and …
Biotechnologies for identification of microorganisrns colonizing aerosol and surfaces of works of art in indoor environrnents
2012
Biological deterioration of organic and inorganic objects is a compIex process involving a relevant number of microbi al species. Particularly. fungi é1nd bacteria, wide spread in biosphere environments, are the main microorganisms related to the biodeterioration o[ cultural property. Moreover, complex microbial communities can relcase, in indoor environments, metabolic products or other airborne particles that may be detrimenral for human health, In order lo identify the components of microbial populations colonizing surfaces of works o[ art and/ or dispersed in thc aerosol of confìned/semi-confined environments, a molecular approach was laken. Samples were collected by non-destructive tec…
Freedom, Civility and Activeness. On the government of leisure self-formation of Finnish multicultural youth
2012
This article explores the leisure time and civic activities of ‘multicultural youth’ in Finland. The theoretic-conceptual framework is the Foucauldian governmentality approach and Foucault's four step model of the ethical self-formation of the moral subject. This toolkit exposes how the subjectivation of the multicultural youth takes place in their leisure time activities and civic action, and connects and disconnects with the desires and expectations of administration and youth workers. The leisure time subjectivation of the youth implements on the interface of their own ‘self-driven’ activities and interests and more or less programmatic governance of official youth work with its integrat…

New species of Deinogalerix (Mammalia, Eulipotyphla) from the late Miocene of Scontrone (Abruzzo, central Italy)
2017
Deinogalerix is a typical component of the late Miocene insular fauna of Gargano (south-eastern Italy). Remains of this taxon had also been found over the last 20 years at the early Tortonian site of Scontrone (Abruzzo, central Italy), but they had never been described in detail. Two new species are introduced. One of them, D. samniticus sp. nov., is larger sized and better documented, and received a formal description. The other entity is clearly distinct from D. samniticus sp. nov., but it is merely represented by a single mandible. It is therefore presented here as a different, but undetermined species, Deinogalerix sp. Comparative analyses show that the new species have exclusive dental…
Russian-speaking immigrant teachers in Finnish classrooms : Views and lived experiences in Finnish education
2017
Success of integration depends, amongst other things, on immigrants’ involvement in the host country’s education. Educational differences between home and host countries can either promote or hinder academic progress of immigrants and, consequently, overall process of their integration. The goal of this study is to investigate what effect differences between educational systems of Finland and neighbouring Russia may have on professional induction of Russian-speaking immigrant teachers in Finland. This is done through researching experiences of Russian-speaking teachers in Finnish education. Their views and interpretations of their own eligibility and Finnish schooling practices lay foundati…
Survival, Growth and Mycorrhization of Containerised Pinus sylvestris and Picea abies Seedlings of Different Provenances Outplanted in a Forest Clear…
2017
Abstract We studied field performance of containerised Pinus sylvestris and Picea abies seedlings of different provenances. Shoot height, needle chemical composition, root collar diameter, root mycorrhization and mycorrhizal species composition were evaluated after four growing seasons following outplanting. The results showed that in general spruce had better survival than pine. Ectomycorrhizas on spruce were dominated by Wilcoxina, Amphinema and Tylospora, while on pine — by Suillus and Thelephora species. Spruce and pine showing best growth rates were colonised by ectomycorrhizal fungus Amphinema sp. In conclusion, the results demonstrated that forest nursery practices as well as provena…
The Lotus japonicus ROP3 Is Involved in the Establishment of the Nitrogen-Fixing Symbiosis but Not of the Arbuscular Mycorrhizal Symbiosis
2021
Legumes form root mutualistic symbioses with some soil microbes promoting their growth, rhizobia, and arbuscular mycorrhizal fungi (AMF). A conserved set of plant proteins rules the transduction of symbiotic signals from rhizobia and AMF in a so-called common symbiotic signaling pathway (CSSP). Despite considerable efforts and advances over the past 20 years, there are still key elements to be discovered about the establishment of these root symbioses. Rhizobia and AMF root colonization are possible after a deep cell reorganization. In the interaction between the model legume Lotus japonicus and Mesorhizobium loti, this reorganization has been shown to be dependent on a SCAR/Wave-like signa…
Data from: Parasitic wasp-associated symbiont affects plant-mediated species interactions between herbivores
2018
Microbial mutualistic symbiosis is increasingly recognised as a hidden driving force in the ecology of plant–insect interactions. Although plant‐associated and herbivore‐associated symbionts clearly affect interactions between plants and herbivores, the effects of symbionts associated with higher trophic levels has been largely overlooked. At the third‐trophic level, parasitic wasps are a common group of insects that can inject symbiotic viruses (polydnaviruses) and venom into their herbivorous hosts to support parasitoid offspring development. Here, we show that such third‐trophic level symbionts act in combination with venom to affect plant‐mediated interactions by reducing colonisation o…
SEAty_ living beyond the waterfront dynamics outcomes and risk of a new trend
2011
The growing number of projcts for floating structures or artificial islands in response to the problems of urhan congestion or environmental emergency requires a critical reflection on the prospectives and the risks implied in this new trend of urban water colonization. This paper intends to test the hypothesis thaht the value of a new and emerging issue of Architecrure can be recognized to this trend and, trhrough a comparison with a series of experiences, wants to bring to the attention of the debate a number of questions which, for exigency of synthesis, analyze in particular the morpholinguistic issues re1ated to the diffusion of this new architecture theme.
