Adsorption of anionic dyes onto natural, thermally and chemically modified smectite clays
2014
Abstract The aim of this study was to determine the adsorption capacity of the smectite clays (from the overburden of the lignite deposit in Belchatow) for two anionic dyes, i.e. Reactive Blue 81 (RB-81) and Direct Blue 74 (DB-74). Additionally, the influence of the thermal and chemical (acid and alkali) clay modifications on the amount of bonded dyes was investigated. The adsorption capacity of the clay (natural and modified) was different for studied dyes and depended on the initial concentration and modification type. All the modified clays adsorbed the dyes at pH>pHPZC as the negatively charged surfaces of their particles (in accordance with the formula: AOH ↔ AO- + H+) prevented the…
Network position and innovation capability in the regional innovation network
2019
This paper investigates the positioning of actors characterized by different natures in a regional innovation network and explores how these actors improve their innovation capabilities by assuming prominence or brokering positions. Innovation capability is widely seen to be the driving force in building regional competitive advantage, therefore investigating how the positioning of actors improves their innovation-related activities is relevant in terms of regional competitiveness. This paper builds on a survey conducted on the Sicilian regional area in Italy. A questionnaire was used to collect data concerning the relationships established between actors and the extent to which these relat…
L'ENTE PUBBLICO ECONOMICO. Il modello siciliano e l'Az.A.Si.
Il lavoro dottorale, assumendo come punto di osservazione l’esperienza dell’Azienda Asfalti Siciliani e- in controluce- dell’Ente siciliano per la promozione industriale e dell’Ente minerario siciliano, mette a fuoco, nelle sue luci ed ombre nonché nei suoi tratti di spiccata originalità, il modello regionale di intervento dei pubblici poteri nello scacchiere economico. L’indagine prende le mosse da un’articolata ricostruzione in chiave storica dell’epopea della Regione imprenditrice onde addivenire ad una profonda rivisitazione della fenomenolgia dell’impresa pubblica calibrata sulla riconcettualizzazione dello scopo di lucro alla stregua di autentico tratto distintivo dell’attività impren…
La expansión de la civilización industrial y sus límites
2021
El presente capítulo aborda los límites de la expansión de la civilización industrial. Tras analizar el legado de esperanzas y amenazas del siglo XXI, se centra en el paso de los límites al crecimiento del Informe del Club de Roma en 1971 al crecimiento de los límites en el inicio del siglo XXI. Por último analiza las interrelaciones entre la sociología, la ecología y la globalización neoliberal
The Influence of Industrial Waste on the Magnetic Properties of Salt-Affected Soils from Two Soda Ash Manufacturing Sites
2021
The aim of this study was to characterize the impact of soda ash manufacturing on the magnetic properties of soils located in the agricultural landscape in north-central Poland. Two study sites were chosen: Mątwy (SM) and Janikowo (SJ). Highly saline soils with halophyte communities were selected in order to develop an understanding of the relationship between salinization of water–soil interface and the potential contamination risk of the environment. Basic chemical and physicochemical properties of topsoil (0–25 cm) and water (surface and groundwater) samples from five locations were characterized. The characteristics of soil contamination were based on the content of sel…
A simple field method to measure the hydrodynamic properties of soil surface crust
2013
The hydraulic resistance of the surface crust was determined by a combination of two infiltrometric techniques: first, a surface measurement of steady-state infiltration rate is conducted by a mini-disk tension infiltrometer (MDI); then, the surface crust is removed, its thickness is measured, and a ponded infiltration test is performed at the same site. The Beerkan Estimation of Soil Transfer parameters (BEST) method is applied to estimate the hydraulic properties of the underlying soil provided the particlesize distribution and the bulk density are known. Under the assumption of a unit gradient of hydraulic head below the soil crust, the pressure head at the interface crust-soil is derive…
miMic
2016
miMic, a sonic analogue of paper and pencil is proposed: An augmented microphone for vocal and gestural sonic sketching. Vocalizations are classified and interpreted as instances of sound models, which the user can play with by vocal and gestural control. The physical device is based on a modified microphone, with embedded inertial sensors and buttons. Sound models can be selected by vocal imitations that are automatically classified, and each model is mapped to vocal and gestural features for real-time control. With miMic, the sound designer can explore a vast sonic space and quickly produce expressive sonic sketches, which may be turned into sound prototypes by further adjustment of model…
Presentazione
2015
All in One è una camera da letto in cartone dalle dimensioni minime che mette insieme i temi dell’arredo trasformabile, del prodotto ecosostenibile e dell’abitare temporaneo; il progetto è portatore di un rigore etico e insieme funzionale. Il design diventa lo strumento che invita al cambiamento. Il tema del neo-nomadismo connesso ai nuovi stili di vita e ai nuovi modi di viaggiare nel rispetto dell’ambiente s’intreccia con i temi della sostenibilità e dell’utilizzo di materiali riciclabili e riciclati, della leggerezza (tanto cara a Italo Calvino nelle sue Lezioni americane) e della trasportabilità.
To embody or not to embody: A sound design dilemma
2019
Designing with sound is about constructing appropriate sound representations of a concept, from the early ideas to the final product. A survey research on embodied sound sketching is presented, and the problems of early representation in sound design are discussed by analysing the questionnaire results of three workshops on vocal sketching.
Outils innovants pour la création d’esquisses sonores combinant vocalisations et gestes
Les designers produisent différents types de représentations physiques et/ou digitales lors des différentes phases d'un processus de design. Ces objets intermédiaires de représentation permettent et supportent l'incarnation des idées du designer, de les externaliser, mais aussi la médiation entre les personnes qui sont impliquées dans les différentes phases du design (designers produits, ingénieurs, marketing, ...). Les designers sonores, eux aussi, produisent des sons intermédiaires pour les présenter aux commanditaires par un processus itératif de raffinement de ces propositions. Ainsi ces différents sons intermédiaires sont des esquisses sonores qui représentent les différentes étapes in…
