The reason for a project that was never performed: Alvar Aalto and the residential complex in Pavia (1966-68)
2015
This paper aims to analyze the characteristics of the project for the residential complex "Patrizia" in Pavia by Alvar Aalto (1966-1968). Although not realized, for political and economic reasons, the project offers an interesting example of urban planning in an “organic key”. In particular, this paper aims to contextualize the project of Aalto in the broader context of the residential building in Italy after World War II, when the problems of reconstruction and "home" are the heart of the debate on architecture. The project, in fact, takes place in the years immediately following the experiments of the social housing plan INA CASA (1949-63), which - with differences in design and architect…
Antimicrobial Lubricant Did Not Reduce Infection Rate in Transrectal Biopsy Patients in a Large Randomized Trial Due to Low Complication Rates
2018
Abstract Background Transrectal prostate biopsy (pbx) is the most frequent outpatient procedure in the urological field. Septic complications are a major health issue. Objective To evaluate complication rates with or without an antimicrobial lubricant. Design, setting, and participants A total of 1000 patients received pbx between 2013 and 2015. Information about complications was collected by a 3-wk questionnaire. Return rate was 73.2% (n = 732). Intervention Randomization for pbx with the instillation of an antimicrobial lubricant (intervention group, n = 385) or the standard lubricant (control group, n = 347) was performed. Outcome measurements and statistical analysis Multivariable anal…
Myxoma virus Leukemia-associated protein is responsible for major histocompatibility complex class I and Fas-CD95 down-regulation and defines scrapin…
2002
ABSTRACTDown-modulation of major histocompatibility class I (MHC-I) molecules is a viral strategy for survival in the host.Myxoma virus, a member of thePoxviridaefamily responsible for rabbit myxomatosis, can down-modulate the expression of MHC-I molecules, but the viral factor(s) has not been described. We cloned and characterized a gene coding for an endoplasmic reticulum (ER)-resident protein containing an atypical zinc finger and two transmembrane domains, which we called myxoma virus leukemia-associated protein (MV-LAP). MV-LAP down-regulated surface MHC-I and Fas-CD95 molecules upon transfection; the mechanism probably involves an exacerbation of endocytosis and was lost when the ER r…
Il caso studio del progetto europeo MAPS. Aree militari come spazi pubblici
2018
La call riguarda l’esperienza progettuale sviluppata dal gruppo di ricerca del Politecnico di Milano – Polo territoriale di Piacenza - nell’ambito del Progetto europeo MAPS (Military Assets as Public Spaces), sostenuto dal programma europeo URBACT per lo sviluppo di politiche urbane. Questa partecipazione ha dato l’occasione ai diversi componenti dell’unità operativa di sperimentare processi di condivisione e di ricerca sul significato di spazio pubblico oggi nella città contemporanea, soprattutto in contesti dismessi e di fragilità. La rete del progetto era costituita da dieci città di altrettanti paesi europei, di cui il Comune di Piacenza è stato capofila: Serres (Grecia), Varazdin (Croa…
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…
Appendix – Additional Measurements
2016
This appendix deals with the determination of different soil physical and hydraulic characteristics used in the analysis and/or interpretation of the infiltration experiments. The core method and the excavation method for measurement of soil bulk density are initially presented. Determination of soil water content by the thermo-gravimetric and the Time Domain Reflectometry methods is then illustrated. Subsequently, field measurement of soil water matric potential by tensiometers is discussed. Laboratory determination of the soil water retention curve by tensiometric and pressiometric techniques is also described. Finally, different methods to test water stability of soil aggregates are illu…
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…
Isolated childhood growth hormone deficiency: a 30-year experience on final height and a new prediction model
2022
Purpose We aimed to evaluate the near-final height (nFHt) in a large cohort of pediatricpatients with growth hormone deficiency (GHD) and to elaborate a new predictive method of nFHt. Methods We recruited GHD patients diagnosed between 1987 and 2014 and followed-up until nFHt. To predict the values of nFHt, each predictor was run in a univariable spline. Results We enrolled 1051 patients. Pre-treatment height was -2.43 SDS, lower than parental height (THt) (-1.09 SDS, p < 0.001). The dose of recombinant human GH (rhGH) was 0.21mg/kg/week at start of treatment. nFHt was -1.08 SDS (height gain 1.27 SDS), higher than pre-treatment height (p < 0.001) and comparable to THt. 1.6% of the pat…
Effect of biochar on the physical and structural properties of a sandy soil
2019
Abstract Biochar application to soil can be considered as a means to improve soil quality, thereby optimizing irrigation management and reducing irrigation needs, especially in dryland regions. This paper is aimed at investigating the effect of biochar (BC) on a desert sandy soil (Al Foah, United Arab Emirates) in terms of bulk density, porosity, water retention, plant available water (AWmax), aggregate stability (AS) and specific surface area (BET-SSA). BC was produced from forest biomass (Italy). Soil water retention was measured by the High Energy Moisture Characteristic (HEMC) and by pressure plate measurements, by using BC fractions equal to 0 (soil only), 0.014, 0.091, 0.23, 0.33 and …
