Alcune considerazioni sul processo di costruzione degli indicatori composti
2008
In questo lavoro si illustra il processo di costruzione di un indicatore composto, espresso nella forma IC = f[T1(x1), T2(x2), …, TJ(xJ)], dove IC è l’indicatore composto, xj sono gli indicatori semplici, Tj sono le trasformazioni e f è la funzione di aggregazione. L’obiettivo del lavoro concerne due aspetti: il primo è l’analisi delle proprietà statistiche e matematiche delle Tj per tentare di individuare misure delle loro performance (per es. variabilità, resistenza, etc.), condizionatamente alla natura dei dati; il secondo è fornire indicazioni circa l’adeguatezza di alcune Tj non lineari, basate sui ranghi e molto usate in pratica, per costruire un buon indicatore composto.
Formare docenti creativi per costruire una società democratica e inclusiva
2023
Questo contributo si ispira a Mario Lodi e alla sua concezione della scuola come luogo potenziale in cui scoprire, nell’età dello sviluppo, le proprie capacità ma anche le proprie preferenze e i propri desideri e, nello stesso tempo, come contesto in cui sperimentare la dimensione comunitaria e di gruppo per potere divenire adulti consapevoli e attenti al bene comune. Il termine “potenziale” è utilizzato perché la scuola può non arrivare ad assolvere il suo compito ma, al contrario, contribuire a conformare il pensiero, a diffondere una cultura della competizione e a perpetuare le disuguaglianze. Benchè ci siano stati sicuramente cambiamenti significativi, legati anche alle trasformazioni s…
ASSOCIAZIONE DI SERENOA REPENS, URTICA DIOICA E PINUS PINASTER. SICUREZZA ED EFFICACIA NEL TRATTAMENTO DEI SINTOMI DEL BASSO TRATTO URINARIO. STUDIO …
2010
INTRODUCTION. Serenoa repens (saw palmetto) has been employed for the treatment of lower urinary tract symptoms (LUTS) for several years. Its mechanism of action is believed to be due to antiandrogenic, antiproliferative and antinflammatory properties. An association of Serenoa with the nettle “Utica dioica” showing antiproliferative activity and the pine “Pinus pinaster” derivative, showing antinflammatory action, has been proposed in recent years. Such an action is hoped to act not only by reducing LUTS but also by preventing the development of prostate cancer. MATHERIAL AND METHODS. During the years 2007 and 2008, 320 patients suffering from LUTS were treated with an association of Seren…

Testing different approaches to characterize Burundian soils by the best procedure
2011
Abstract The Beerkan Estimation of Soil Transfer parameters (BEST) procedure seems attractive for soil hydraulic characterization but it has received little testing so far. The objective of this investigation was to test BEST with different application approaches for some soils in Burundi, where there is the need of using simple methods to characterize soils. Most (14) of the 19 sampled sites had a clay soil texture whereas texture ranged from silty clay to loam in the other cases. On average, the fitting ability of both the particle size distribution (PSD) model (mean relative error, Me ( E r ) = 2.0%) and the cumulative infiltration model ( Me ( E r ) = 2.3%) was good according to recomme…
Infiltration Measurements for Soil Hydraulic Characterization
2016
This book summarises the main results of many contributions from researchers worldwide who have used the water infiltration process to characterize soil in the field. Determining soil hydrodynamic properties is essential to interpret and simulate the hydrological processes of economic and environmental interest. This book can be used as a guide to soil hydraulic characterization and in addition it gives a complete description of the treated techniques, including an outline of the most significant research results, with the main points that still needing development and improvement.
Determining hydraulic properties of a loam soil by alternative infiltrometer techniques
2015
Testing infiltrometer techniques to determine soil hydraulic properties is necessary for specific soils. For a loam soil, the water retention and hydraulic conductivity predicted by the BEST (Beerkan Estimation of Soil Transfer parameters) procedure of soil hydraulic characterization was compared with data collected by more standard laboratory and field techniques. Six infiltrometer techniques were also compared in terms of saturated soil hydraulic conductivity, Ks. BEST yielded water retention values statistically similar to those obtained in the laboratory and Ks values practically coinciding with those determined in the field with the pressure infiltrometer (PI). The unsaturated soil hyd…
DETERMINING THE SATURATED HYDRAULIC CONDUCTVITY OF A LOAM SOIL WITH DIFFERENT INFILTROMETER TECHNIQUES
2015
The saturated soil hydraulic conductivity, Ks, is one of the most important soil hydraulic properties since it controls many hydrological processes. This hydrodynamic parameter depends on soil texture and structure and it is very difficult to measure. Infiltrometer techniques are becoming very popular to determine Ks in the field but testing alternative approaches is necessary for specific soil types. For a loam soil, the estimated Ks values with six infiltrometer techniques were compared. The so-called BEST procedure of soil hydraulic characterization, the pressure infiltrometer (PI), single head experiments with both the tension infiltrometer (TI) and the mini disk infiltrometer (MDI), th…
