Large scale seismic vulnerability and risk evaluation of a masonry churches sample in the historical centre of Naples

This paper investigates about the seismic vulnerability and risk of fifteen masonry churches located in the historical centre of Naples. The used analysis method is derived from a procedure already implemented by the University of Basilicata on the churches of Matera. In order to evaluate for the study area the seismic vulnerability and hazard indexes of selected churches, the use of appropriate technical survey forms is done. Data obtained from applying the employed procedure allow for both plotting of vulnerability maps and providing seismic risk indicators of all churches. The comparison among the indexes achieved allows for the evaluation of the health state of inspected churches so to program a priority scale in performing future retrofitting interventions

Biomimetic implant surface functionalization with liquid L-PRF products: in vitro study

Abstract Objective: Platelet-rich fibrin (PRF) clots and membranes are autologous blood concentrates widely used in oral surgical procedures; less is known, however, about the liquid formulations of such products. The aim of this in vitro study is to assess the behavior of different implant surfaces when in contact with two liquid leucocyte- and platelet-rich fibrin (L-PRF) products. Methods: Six commercial pure titanium discs, of 9.5 mm diameter and 1.5 mm thickness, were used. Three of these samples had a micro/nano-rough surface; three were machined. Three different protocols were tested. Protocols involved the immersion of the samples in (1) a platelets, lymphocytes, and fibrinogen liquid concentrate (PLyF) for 10 minutes, (2) an exudate obtained from L-PRF clots rich in fibronectin and vitronectin for 5 minutes, and (3) the fibronectin/vitronectin exudate for 2 minutes followed by immersion in the PLyF concentrate for further 8 minutes. After these treatments, the samples were fixed and observed using a scanning electron microscope (SEM). Results: Under microscopic observation, (1) the samples treated with the PLyF concentrate revealed a dense fibrin network in direct contact with the implant surface and a significant number of formed elements of blood; (2) in the samples treated with the fibronectin/vitronectin exudates, only a small number of white and red blood cells were detectable; and (3) in samples exposed to the combined treatment, there was an apparent increase in the thickness of the fibrin layer. When compared to the machined surface, the micro/nano-rough samples showed an overall increased retention of fibrin, leading to a thicker coating. Conclusions: Liquid L-PRF products promote the formation of a dense fibrin clot on micro/nano-rough implant surfaces in vitro. The adjunctive treatment of surfaces with the fibronectin/vitronectin exudate could provide support to contact of the fibrin with the surface, though it is not essential for the clot formation. Further studies are necessary to better elucidate the properties and benefits of liquid L-PRF products

Il consumo tribale nello sport. Il caso del ciclismo amatoriale: analisi teorica ed empirica.

Una tribù postmoderna è un gruppo temporaneo ed eterogeneo di persone, accumunati da interessi in comune. Nella trattazione si tratterà inizialmente dell’aspetto sociale delle comunità tribali postmoderne, definite così perché richiamano alla memoria le tribù arcaiche dal punto di vista degli usi e delle pratiche sociali. Ne verranno quindi analizzate le caratteristiche, cioè eterogeneità, passione condivisa, esistenza di interrelazioni, temporaneità e multi appartenenza tribale. Successivamente si affronterà il consumo tribale attraverso l’aspetto economico, e quindi la relazione esistente tra le tribù e le aziende, o i prodotti. Sotto questo punto di vista si classificheranno quattro tipologie di tribù: tribù come attivatori, tribù come saccheggiatori, tribù come imprenditori e tribù doppiogiochiste. Dopo aver ampiamente descritto le caratteristiche di ciascuna tipologia, con vari esempi concreti, verrà affrontato il tema delle tribù sportive, e in particolar modo quello delle tribù ciclistiche. In seguito verrà fatto un riepilogo storico sul ciclismo e sulla bicicletta, nonché un’analisi dal punto di vista sportivo, con una breve spiegazione delle varie discipline sportive, e dal punto di vista economico, con delle valutazioni sul mercato interno ed esterno. È stata presa in analisi una tribù ciclistiche, raggiunta tramite un forum di ciclismo amatoriale, e ne verranno analizzate dapprima attività (online e offline) e linguaggio, successivamente gli utenti più attivi all’interno del gruppo e infine i ruoli assunti nella comunità

Management control of contractual networks: the business network scorecard

The paper presents an analysis of the management control systems, introducing a useful instrument to summarise performance achieved from the organizational network model, with a view to establishing the competitive advantage and the creation of value on the long term. The research approach is based on the qualitative methodology. The research is developed according to the study of national and international literature. The contribution proposes theoretical proof to support the new management control instrument for contractual networks: the Business Network Scorecard. The approach adopted for the development of the network management control instrument (Business Network Scorecard) refers to the principles of the Balanced Scorecard and value creation. So, the reporting system of network performance aims at highlighting the joint results of an economic-financial nature as well as those of an intangible nature. Through a logic of interception of large aggregates, the results achieved by the network are proposed through the matrix of network objectives, the multidimensional network model, including perspective indicators, 4 indicators of synergy and the comparison report of joint and individual performance of companies

Concept, prototyping and application of a tensioning system for FRP ties into masonry structures

The present paper deals with concept, prototyping and application of a tensioning system for FRP ties into masonry structures. The proposed system, based on the use of FRP strands instead of traditional steel ties, has the aim to produce a compression stress state on masonry walls where it is applied. Given the objective difficulty in tensioning a FRP strand, it has been necessary to both characterize and prototype a suitable connection system between the strand and the pulling system. The experimental phase concerned both the manufacturing of the pulling system and the study of used materials, as well as the characterization of the impregnation technology of FRP ties. The above described system has been produced and used in the framework of the structural retrofitting of the “Real Albergo dei Poveri” building in Naples

Transcriptomic analysis of two sheep breeds during lactation, using a new custom microarray platform

Individual milk samples were weekly collected from 48 ewes during eight weeks. Ewes were at the second month of lactation and they were fed the same dietary regimen. The animals were grouped according to the amount of daily milk fat yield: A) 38-57g/d, B) 58-63g/d, C) 64-73g/d, D) 75-110g/d. Milk from group D showed a higher content of FA from C4 to C10 and a lower content of monounsaturated FA (MUFA) and conjugated linoleic acids (CLA) than Group A (+12%, -11%, and -18%, for C4 to C10, MUFA and CLA, respectively), while Group B and C showed intermediate values. CLA content increased with days of lactation in a similar way for all groups. The mean correlation among all records within each individual lactation was 0.45 for CLA content. Six milk FA pair ratios representing a proxy for SCD activity were also evaluated: group A showed higher values of FA ratios than Group D (+26% on average for all FA pairs). In conclusion, increasing ability of daily milk fat yield was associated with lower milk content of MUFA and CLA and higher content of FA from C4 to C10

Changes of Oxytocin and Serotonin Values in Dialysis Patients after Animal Assisted Activities (AAAs) with a Dog-A Preliminary Study

Simple Summary This study aimed to improve the moment of dialysis because the emotional management of a person during treatment can help to reduce stress, anxiety and depression. This process positively affects the acceptance and progress of treatment and improves the self-management of the disease, a very important achievement in chronic kidney disease. Serotonin and oxytocin are important neuromodulators of different human behaviours, such as affectivity and socialization, and are involved in the control of stress, anxiety and social cooperation. The relationship between humans and domestic animals provides psychophysical well-being and can facilitate interpersonal bonds by favouring mechanisms involved in social relations. Dogs due to their ethological characteristics, allow the establishment of an active relationship through play, communication and interaction. Animal-assisted activities (AAAs) are structured interventions aimed at improving the psychophysical conditions of people in stressful conditions. Our study was aimed at determining the circulating levels of serotonin and oxytocin in patients who participated in an AAAs program with a dog during dialysis treatment. Our study aimed to measure the levels of serotonin and oxytocin in patients affected by end-stage renal disease (ESRD), undergoing dialysis and participating in a program of animal-assisted activities (AAAs) with a dog. Ten patients with comparable levels of ESRD were enrolled. A blood sample was taken before the start of the study in order to establish basal levels. Eleven meetings were held once a week for 3 months during the last hour of dialysis, and blood samples were collected before and after AAAs. Two more meetings, one month apart from each other, were held two months later without the dog but with the same veterinarian zootherapist. Blood was drawn at the beginning and at the end of each meeting. The samples were then processed for the measurement of serotonin and oxytocin, and data obtained were analysed using analysis of variance with mixed effect models. The results show an increasing level of both serotonin and oxytocin between subsequent meetings with the dog and an increasing trend of inter-intervention levels. Overall, the results suggest that AAAs lead to modifications of serotonin and oxytocin levels, which are also accompanied by behavioural changes of patients
