Nicotinamide adenine dinucleotide phosphate-diaphorase (NADPH-d) is a key enzyme in the synthesis of the gaseous neurotransmitter nitric oxide. We compare the distribution of NADPH-d in the brain of four species of hylid frogs. NADPH-d-positive fibers are present throughout much of the brain, whereas stained cell groups are distributed in well-defined(More)
The present study aimed at evaluating possible behavioural differences between guide dogs living in a kennel and interacting with a trainer and those living in a house and interacting with a blind person and their family, when they are faced with an unsolvable task. Fifty-two Labrador retrievers were tested: 13 Trained Guide dogs at the end of their(More)
Introduction. This work is to be set within the study context of supervised classification tree-based model. This methodology, according to CART approach (Breiman et al. 1984) allows to build a tree-structure to describe the dependence links between an independent variable and a set of explicative variables in regression and classification matters. The(More)
Riassunto: La segmentazione con criterio di split a due stadi si propone di definire procedure di classificazione/regressione ad albero in cui i predittori giocano un ruolo globale e locale nella spiegazione della variabile dipendente. Ciò avviene attraverso l'impiego di indici statistici, modelli parametrici e tecniche fattoriali. Il presente lavoro mostra(More)
The paper investigated drivers' speed behaviour in a section of a rural highway crossing a small urban community in the existing scenario without any traffic calming device and in two different design scenarios with traffic calming in the urban community. Two gateways and four integrative traffic calming devices along the route within the urban area were(More)
Data Fusion and Data Grafting are concerned with combining files and information coming from different sources. The problem is not to extract data from a single database, but to merge information collected from different sample surveys. The typical data fusion situation formed of two data samples, the former made up of a complete data matrix X relative to a(More)
Our paper analyses 25 years of performance management research published in the English-language journals, included in SSCI database, separating the business domain from public sector one. We used a content analysis for showing the relationships between the subfields of performance management and the time evolution. Through a multiple correspondence(More)
OBJECTIVE To evaluate the possible crosstalk between C-X-C chemokine receptor 4 (CXCR4)/C-X-C motif chemokine 12 (CXCL12)/C-X-C chemokine receptor 7 (CXCR7) axis with the mammalian target of rapamycin (mTOR) pathway in neuroendocrine tumors (NETs). METHODS Sixty-one human NETs were included into the study. CXCR4/CXCL12/CXCR7 axis and mTOR pathway were(More)
