La metodologia Sei Sigma nei servizi

This book explains how the methodological approach of the Six Sigma can be used to provide an effective solution to one of the most widespread problems faced by Small and Medium Enterprises: the frequent undercapitalisation linked to short-term investments often funded by bank loans. The Six Sigma method enables the problem to be tackled by studying, in an analytical and statistical manner, both the payments that the enterprises are to receive and the possible conditions of the funding, proposing solutions to optimise these processes and improve the financial performance of the SMEs. Hence the book is offered as both a methodological analysis and as an operative tool for the sphere of enterprise.Il libro mostra come l'approccio metodologico del Sei Sigma possa essere utilizzato per fornire un'efficace soluzione ad un problema molto sentito dalle Piccole e Medie Imprese: la frequente sottocapitalizzazione legata agli investimenti a breve periodo, spesso finanziati con dei prestiti bancari. La metodologia Sei Sigma permette di affrontare il problema studiando in modo analitico e statistico sia i pagamenti che le aziende devono ricevere, sia le possibili condizioni di finanziamento, proponendo delle soluzioni per ottimizzare questi processi e migliorare la performance finanziaria di una PMI. In tal senso si propone allo stesso tempo come un saggio di analisi metodologica e come uno strumento operativo per la realtà imprenditoriale

Experimental Assessment of Correlative Approaches for the Prediction of Leakage Flow through Labyrinth Seals

Simple analytical models can be employed to estimate the leakage mass flow rate from labyrinth seals, resulting in a quick procedure, well suited for the early design process. Different formulas were proposed by many authors during the past decades and most of them employ a carry-over factor and a flow coefficient to predict the mass flow rate across the clearance area. The present work aims to compare the analytical prediction with the results of an experimental campaign. The experimental results were retrieved from a dedicated test rig for both a straight-through and a stepped labyrinth seal. Hence, for each seal, the effect of the clearance size, the Reynolds number and the pressure ratio has been investigated. Starting from the experimental required inputs, six different correlations are considered, with both direct and indirect methods. The results are shown as a function of pressure ratio and clearance gap. Despite some differences in the comparison, and most of the used correlation underestimate the measured mass flow rate, some general trends and guidelines can be highlighted

Porcine <i>Lawsonia intracellularis</i> Ileitis in Italy and Its Association with Porcine Circovirus Type 2 (PCV2) Infection

The objective of this study was to employ a diagnostic algorithm, which involves detecting positive farms by stool PCR followed by PCR and histology/immunohistochemistry on ileum samples, for diagnosing Lawsonia intracellularis proliferative enteritis in Northern Italy. The primary aim was to examine the relationship between the gold standard of L. intracellularis diagnostics, namely histology and immunohistochemistry, and PCR in acute and chronic cases of L. intracellularis enteritides. An additional goal was to investigate the coinfection of L. intracellularis with porcine circovirus type 2 (PCV2). Twenty-eight ileum samples, including four from acute cases and 24 from chronic cases, were collected. PCR yielded positive results in 19 cases (four acute and 15 chronic cases). In comparison, immunohistochemistry was positive in 16 cases (four acute and 12 chronic cases), with an observed agreement of 89%. The findings suggest that performing the two tests in series can increase the specificity of the causal diagnosis. PCR may be used as a screening tool to identify the presence of the microorganism, and only positive cases will be examined by histology and immunohistochemistry to confirm the causative role of L. intracellularis. Co-infection with PCV2 was demonstrate in two out of four acute cases and in two out of 24 chronic cases, providing further evidence to support the hypothesis that when the infection starts with ubiquitous pathogens such as L. intracellularis, it may boost the possibility of PCV2 replication, especially in acute cases. As a result, this may trigger a transition from subclinical to clinical forms of PCV2 disease
