Transboundary geothermal resources of the Mura-Zala basin: a need for joint thermal aquifer management of Slovenia and Hungary
Annamaria Nador,Andrej Lapanje,Gyorgy Toth,Nina Rman
Geologija , 2012,
Abstract: Large transboundary Upper Miocene geothermal sandy aquifers which are widely utilized by both countries forbalneological and direct heat purposes exist in the Slovenian-Hungarian border region. In NE Slovenia the totaldirect heat use was 382 TJ in 2010, while in SW Hungary it was 648 TJ, including utilization from basement reservoirs.The total installed capacity of the 13 Slovenian users was 38.8 MWt, while that of the 29 Hungarian userswas 70.6 MWt. Utilisation takes place without harmonized management strategies which might endanger the longtermsustainability of these systems. We aimed to overcome this by delineating a transboundary thermal groundwaterbody (TTGWB) Mura-Zala with an aerial extent of 4,974 km2 and with vertical extent between depths 500–2,200 m, which was done based on detailed geological, hydrological, geochemical and geothermal models as wellas numerical modelling. The regional groundwater flow in the Mura-Zala TTGWB is from west to east in general,the modeled cross-border flow is approximately 50 l/s. At present, thermal water abstraction rates from the Mura/újfalu Fm. (61.8 l/s in the Slovenian and 67.3 l/s in the Hungarian part of the TTGWB) does not endanger the goodregional quantity status of the water body, and this should be maintained by allowing a maximum increase of thermalwater abstraction 3.5 times higher than today. However, to achieve target numbers for an increased proportionof geothermal energy in the total energy mix in both countries, we suggest that increase of thermal efficiency andre-injection should be prioritized apart from the higher thermal water abstraction with setting up limit of themaximum allowable drawdown.
Protective Effects of Many Citrus Flavonoids on Cartilage Degradation Process  [PDF]
Lucia Crascì, Annamaria Panico
Journal of Biomaterials and Nanobiotechnology (JBNB) , 2013, DOI: 10.4236/jbnb.2013.43035
Abstract: The objective of this study was to investigate the effects of many citrus flavanones, such as neoeriocitrin, naringin and neohesperidin, in cartilage degradation. Degenerative joint disease involved degradation of joints, including articular cartilage and subchondral bone. When bone surfaces become less well protected by cartilage, bone may be exposed and damaged. The degradation cartilage is mediated by alteration of the balance between anabolic and catabolic processes, changes in proteolytic enzyme activity, mechanical disruption of the cartilage extracellular matrix (ECM), or a combination of these processes. We examine the capability of neoeriocitrin, naringin and neohesperidin, to inhibit metalloproteinase (MMP)-13, collagenase involved in degradation of cartilage matrix components. Also, we assay the flavonoids effect on reducing of Glycosaminoglycans (GAGs) release, and restore Nitric oxide (NO) levels in explant of human articular cartilage. Our results suggest that neoeriocitrin, naringin and neohesperidin are a potential therapeutic agent to protect cartilage tissue.
Strategies, Performances and Profiling of a Sample of U.S. Universities in 2012  [PDF]
Angela Besana, Annamaria Esposito
Open Journal of Applied Sciences (OJAppS) , 2015, DOI: 10.4236/ojapps.2015.53008
Abstract: The global economic crisis is affecting performances of not-for-profits. At the same time donors are targeted by a pressing good-cause related marketing, so that the competition for philanthropy is particularly keen. U.S. universities can be public, not-for-profit and for-profit. U.S. not-for-profit universities are confronted with different marketing, fundraising and revenue diversification. Above all, marketing concerns customers and their segmentation and their purchasing-power exploitation; fundraising aims to gain the trustworthiness of donors, instead. The aim of this paper is the analysis of the revenue diversification of a sample of 100 U.S. not-for-profit universities according to IRS (Internal Revenue Service) Forms. These 100 U.S. universities had the highest 2012’s revenues for the Guidestar ranking (www.guidestar.org). The cluster analysis gives evidence that the highest gain and the highest solvency are both connected with the implementation of revenue diversification for one profile. The most crowded cluster is the Marketing Expert with the second highest gain.
VEP Correlates of Feedback in Human Cortex
Yury Petrov, Jeffrey Nador, Jiehui Qian
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0051791
Abstract: It is known that neural responses become less dependent on the stimulus size and location along the visual pathway. This study aimed to use this property to find evidence of neural feedback in visually evoked potentials (VEP). High-density VEPs evoked by a contrast reversing checkerboard were collected from 15 normal observers using a 128-channel EEG system. Surface Laplacian method was used to calculate skull-scalp currents corresponding to the measured scalp potentials. This allowed us to identify several distinct foci of skull-scalp currents and to analyse their individual time-courses. Response nonlinearity as a function of the stimulus size increased markedly from the occipital to temporal loci. Similarly, the nonlinearity of reactivations (late evoked response peaks) over the occipital, lateral-occipital, and frontal scalp regions increased with the peak latency. Response laterality (contralateral vs. ipsilateral) was analysed in lateral-occipital and temporal loci. Early lateral-occipital responses were strongly contralateral but the response laterality decreased and then disappeared for later peaks. Responses in temporal loci did not differ significantly between contralateral and ipsilateral stimulation. Overall, the results suggest that feedback from higher-tier visual areas, e.g., those in temporal cortices, may significantly contribute to reactivations in early visual areas.

Mountassir Moujahid, Tarik Ziadi, Ahmed Rhari, Karim Nador, Issam Serghini, Moulay Hassan Tahiri
Open Journal of Thoracic Surgery (OJTS) , 2014, DOI: 10.4236/ojts.2014.42007
Abstract: The Askin tumour is a highly malignant rare tumour with small cells, pertaining to the group of the primitive neuroectodermal tumours. It develops with the costs of the soft parts of the thoracic wall and it’s characterized by extra and endothoracic fast extension. We report seven cases colliged in our service by specifying the role of the imagery in the diagnosis but especially the assessment of extension of these tumours.
The rehabilitation of a reservoir: A new methodological approach for calculating the sustainable useful storage capacity  [PDF]
Annamaria De Vincenzo, Bruno Molino
Agricultural Sciences (AS) , 2013, DOI: 10.4236/as.2013.48A007
Abstract:

Present work introduces the sustainable useful storage capacity as the minimum storage capacity able to satisfy the water demand for drinkable, industrial and irrigational purposes and necessary in order to overcome water deficit situations which, at least in Central Southern Italy, occur in the summer, when agricultural demand is really high. Sediment volumes to be removed from the reservoir bottom will be calculated as the difference between the current and the sustainable useful storage capacities of the reservoir in study. The calculation methodology of the useful sustainable storage capacity, based on the reservoir water balance between inflows at the reservoir and water demand, has been applied to the Camastra reservoir (Basilicata, Southern Italy), for which numerous reliable data including more than 40 years of inflows and water supplied volumes and data relative to 7 bathymetric surveys are available. Result analysis shows that this methodology, at least in the study case, enables sediment quantities to be removed more sustainably from a technical, economical and environmental point of view.

The Evolutionary Processes of Canine Coronaviruses
Annamaria Pratelli
Advances in Virology , 2011, DOI: 10.1155/2011/562831
Abstract: Since the first identification of the virus in 1971, the disease caused by canine coronavirus (CCoV) has not been adequately investigated, and the role that the virus plays in canine enteric illness has not been well established. Only after the emergence in 2002 of SARS in human has new attention been focused on coronaviruses. As a consequence of the relatively high mutation frequency of RNA-positive stranded viruses, CCoV has evolved and, with the biomolecular techniques developed over the last two decades, new virus strains, serotypes, and subtypes have been identified in infected dogs. Considering the widespread nature of CCoV infections among dog populations, several studies have been carried out, focusing upon the epidemiological relevance of these viruses and underlining the need for further investigation into the biology of CCoVs and into the pathogenetic role of the infections. This paper reports the evolutionary processes of CCoVs with a note onto recent diagnostic methods. 1. Coronaviruses: Genome and Structure Coronaviruses (CoVs), a genus in the Coronaviridae family, order Nidovirales, are large, enveloped, RNA viruses that cause highly prevalent diseases in humans and domestic animals. CoVs are spherical enveloped particles about 100–120?nm in diameter with a capped, polyadenylated single-stranded, positive-sense genomic RNA 27.6 to 31?kb in length, the largest known RNA virus genome. The 5′ end of the genome consists of a 65 to 98?nt sequence, termed the leader RNA, that is also present at the 5′ end of all subgenomic mRNAs. An untranslated region (UTR) of 200 to 400?nts follows this leader sequence. At the 3′ end of the RNA genome is another UTR of 200 to 500?nts followed by a poly(A) sequence of variable length. Both 5′- and 3′-UTRs are important for RNA replication and transcription. The remaining genomic sequence includes different open reading frames (ORFs) which differ markedly among coronaviruses in number, nt sequence, genes order, and in method of expression. At the 5′ end of each gene, all CoVs have a common intergenic sequence of about 7 bases which is essential for the formation of subgenomic RNAs [1]. The first two-thirds of the genome consists of two partially overlapping ORFs, ORF1a and ORF1b. These ORFs are translated into a polyprotein which is the precursor both of the viral RNA-dependent RNA polymerase and of proteases. The one-third in the 3′ end of the genome contains ORFs encoding for the major structural proteins, spike (S), envelope (E), membrane (M), and nucleocapsid (N) proteins. These ORFs are interspersed with

The paradigm of métissage, between aesthetics and human sciences Il paradigma del métissage, fra estetica e scienze umane
Annamaria Contini
Ricerche di Pedagogia e Didattica , 2009,
Abstract: The paper aims at reconstructing the paradigm of the métissage (crossbreeding), as it was developed in the social sciences of the French speaking countries: an approach to the problems caused by globalisation and by the more and more frequent interethnic contacts, which is characterized by its interdisciplinary nature, by the great importance ascribed to the concept of alterity (otherness) in the identity building and by the as much deciding function attributed to the art of creation and/or interpretation of the cultural contamination processes. The analysis of the perspectives of édouard Glissant, Serge Gruzinski, Fran ois Laplantine and Alexis Nouss highlights the mutual involvement between aesthetics and education: while the art production shows the dynamic and relational character of cultural identities, it emphasizes an often underestimated effect of the hybridisation and métissage processes: their creative potential, e.g. the original configurations they are able to create, even if social and power relation are inequal and asymmetrical. L’articolo si propone di ricostruire il paradigma del métissage, così come si è affermato nelle scienze sociali di area francofona: vale a dire, un approccio ai problemi posti dalla globalizzazione e dai sempre più frequenti contatti interetnici, che si contraddistingue per la vocazione transdisciplinare, per il ruolo cruciale assegnato all’alterità nella costruzione dell’identità e per la funzione parimenti decisiva attribuita all’arte nella fabbricazione e/o nella decifrazione dei processi di contaminazione culturale. Dall’analisi delle prospettive di édouard Glissant, Serge Gruzinski, Fran ois Laplantine e Alexis Nouss emerge un modello ricco d’implicazioni sia estetiche che pedagogiche, per cui la produzione artistica, mentre evidenzia il carattere dinamico e relazionale delle identità culturali, mostra un effetto dei processi d’ibridazione e di métissage che viene spesso sottovalutato: la loro creatività, cioè le originali configurazioni a cui possono dar luogo, anche quando le relazioni sociali e i rapporti di potere sono ineguali e asimmetrici.
Sortir de la rue : une lutte pour la reconnaissance à l’heure de l’individualisme avancé
Annamaria Colombo
SociologieS , 2010,
Abstract: Cet article présente les résultats d’une recherche analysant le processus de sortie de la rue des jeunes à Montréal. Les résultats obtenus conduisent à considérer ce dernier comme une lutte pour la reconnaissance dans le contexte actuel d’individualisation croissante du lien social. Dans ce contexte, les tentatives des jeunes pour s’approprier une position sociale peuvent prendre des formes inhabituelles et bricolées telles que l’appropriation de la rue et la sortie de celle-ci. Aspirant à une certaine normalité, les jeunes rencontrés ont investi des contextes relationnels plus ou moins associés à la rue. Ils se sont approprié les manifestations de reconnaissance qu’ils y ont trouvées afin de construire leur sortie de la rue, comprise comme un processus de repositionnement identitaire. Or il ressort également que le sens attribué à ces manifestations de reconnaissance est lourdement influencé par les formes de reconnaissance parentales vécues durant l’enfance. This article presents the results of a research analyzing the processes that street youth use to exit street life in Montreal. The results of this research show that these processes are a form of struggle by the street youth to gain recognition in the current context of growing individualization. In this context, the attempts of youth for the appropriation of a social place can take unusual forms, such as street appropriations and street exits. Aspiring to a certain form of normality, the interviewed youth built relationships more or less associated to street life. They used the recognition manifestations they gained in order to advance the processes of their exit from street life, which should be understood as a process to reposition their identities. The results also show that the sense that the street youth attribute to these recognition manifestations is heavily influenced by the parental recognition forms experienced during childhood. Este artículo presenta los resultados de una investigación que analiza el proceso de “salida” de la calle de los jóvenes de Montréal. Los resultados obtenidos llevan a considerar la “salida” como una lucha de reconocimiento en el contexto actual de la individualización creciente del vínculo social. En este contexto, las tentativas de los jóvenes para ocupar una posición social pueden tomar formas inhabituales tales como: la apropiación de la calle y la “salida” de ella. Aspirando a cierta normalidad, los jóvenes entrevistados invirtieron en contextos de interacción social asociados o distantes de calle. Ellos se han apropiado las manifestaciones de reconocimient
