SUP&R DST: SUstainable pavement & railways decision support tool

2018

6th International Symposium on Life-Cycle Civil Engineering, IALCCE 2018; Ghent; Belgium; 28 October 2018 through 31 October 2018, GHENT, BELGIQUE, 28-/10/2018 - 31/10/2018; In order to help the decisions makers to efficiently address eco-design for transport infrastructure technologies, a decision support toll (DST) was developed in the scope of the training-through-research programme Sustainable Pavements & Railways Initial Training Network (www.superitn.eu). It consists of a computational platform that implements a conceptual framework developed to quantify sustainability. It comes with a set of sustainability indicators tailored to both road and railway systems as well as several ob…

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…

Bērnu praktisko iemaņu attīstošu grāmatu dizaina specifika

2016

Ilustrācija ir viens no veidiem, ka grāmatu produkcija var piesaistīt uzmanību un radīt noskaņojumu. Grāmata ar ilustrācijām piesaista bērnu uzmanību un palīdz vieglāk uztvert teksta ideju. Ideja veidot bērnu pavārgrāmatu tika izvēlēta, jo tāda grāmata attīsta bērnu praktiskās iemaņas un risina aktuālu problēmu, kā bērniem un vecākiem kopā lietderīgi pavadīt brīvo laiku. Pavārgrāmata ir spilgts piemērs, kurā ilustrācijām un tekstam jābūt saskaņotam un jāpapildina vienam otru. Lai panāktu noteikto mērķi, autore ar salīdzinošo pieeju un analīzes metodi pētīja bērnu attīstošās grāmatas. Diplomdarbs sastāv no ievada, trīs nodaļām un apakšnodaļām, secinājumiem un diviem pielikumiem. Darba kopēja…

THE DIAGNOSIS OF ROAD SURFACE DISTRESSES THROUGH IMAGE-BASED MODELING TECHNIQUES. EXPERIMENTAL SURVEY ON LABORATORY-RUTTED SAMPLES

2015

In the past few years, there has been a drastic increase in the use of image-based modeling (IBM) techniques to create high quality, reality-based 3D models. The low costs of these techniques, as well as their attractive visual quality, have led many researchers and professionals to invest their energy and resources in several tests. IBM is rarely used in the field of road surface distresses as diagnosis is usually performed using other techniques and devices. Road safety statistics reveal that about a half of the total number of accidents occur mainly due to the deterioration of the pavement. The goal of effective road network management is often incompatible with economic resources design…

ARCHITETTURA, CUSTODE DELLA NATURA : il progetto di suolo nella trasformazione delle autostrade urbane, 1962-2018

2023

Un inarrestabile cambiamento nel paradigma con cui l’uomo concepisce la propria specie rispetto ai suoi modi di costruire è alla base dell’attrattiva per l’incorporazione del vegetale nell’Architettura. Lo statuto euristico di maggiore capacità di tale nuovo corso è la sostituzione progressiva dell’Ambiente alla Natura fra i motori della Composizione. Su questo sfondo, l’articolo indaga l’ibridazione del vegetale e del costruito nella trasformazione contemporanea delle grandi autostrade urbane, attraverso un approccio diacronico e comparativo, in riferimento a una ricerca internazionale di cui estende l’ipotesi principale. A tal fine, ricostruisce il telaio ermeneutico di riferimento discut…

Modelling pavement surface characteristics for noise prediction through Bailey-related indicators

2021

The aggregate gradation of bituminous mixtures (hot mix asphalts, HMA) is one of the major factors affecting their surface texture. In turn, this latter is a crucial factor and influences drivers and bystanders’ safety, comfort, and health. Despite this, the design of texture levels still lacks sound bases and dedicated algorithms and this negatively affects the acoustic design of bituminous mixtures. Consequently, the objectives of this study were confined into the derivation of relationships to be used in mix design to predict texture levels. Experimental data were analyzed, in the pursuit of setting up appropriate models and algorithms. Analyses involved the consideration of Bailey-relat…

Papaverine enhances the negative inotropic effect of acetylcholine in rat auricles

1978

The negative inotropic effect of acetylcholine in rat left auricles is enhanced in the presence of the phosphodiesterase inhibitor papaverine. This result favours the idea of a cyclic GMP-mediated action of acetylcholine in the heart.

A negative inotropic effect of acetylcholine in the presence of several phosphodiesterase inhibitors.

1981

The phosphodiesterase inhibitors papaverine, theophylline and 3-isobutyl-1-methylxanthine (IBMX) reveal a negative inotropic effect of acetylcholine in cat ventricular heart muscle. This effect in unrelated to beta-adrenoceptor stimulation and possibly mediated by the accumulation of cyclic GMP.

Electrical and mechanical activity of mammalian heart muscle fibres treated with papaverine

1977

The action of papaverine on electrical and mechanical activity was investigated in ventricular and atrial heart muscle fibres from guinea-pigs and cats. 1. Papaverine (10−5 M–5×10−5M) had positive, negative or no inotropic effects in ventricular preparations; positive inotropic effects were not observed after pretreatment of the animals with reserpine. In atrial preparations, papaverine (2×10−5M) had a positive inotropic effect that was independent of endogenously stored catecholamines. 2. The effects of isoprenaline and dibutyryl cyclic AMP were potentiated by papaverine (10−5 M–2×10−5M). 3. The action potential duration was always prolonged by papaverine in ventricular as well as in atria…
