Dal "gelido mostro" all'individuo sociale. De Feo, lo Stato-piano e l'illusione socialista
No full textIl saggio si sofferma sulle analisi che Nicola M. de Feo dedica al Verein für Sozialpolitik in merito al problema del rapporto fra Stato piano, capitalismo e socialismo. Esso pone in luce l'importanza che in queste analisi assumono i temi dell'individuo sociale e dell'autonomia operaia nel condurre de Feo verso una visione del socialismo e del comunismo irriducibile a quelle del movimento operaio ufficiale
Eventi ibridativi e identità molteplici: il mondo senza genesi di Donna J. Haraway
No full textAl centro dell’articolo "Eventi ibridativi e identità molteplici: il mondo senza genesi di Donna J. Haraway" si colloca la riflessione sulle relazioni di scambio intercorrenti tra la rappresentazione sociomorfica del corpo umano e l'orizzonte politico. È intorno all’ibrida figura del cyborg che si stringe il nodo tra organico e inorganico nell’analisi harawayana del complesso intreccio tra biotecnologia, mercato e politica. Il chimerico organismo cibernetico, capace di sperimentare continue metamorfosi, ridelinea il corpo come concetto limite, trasformandolo, nei suoi commerci con l’eteroreferenza macchinica, in un sistema complesso in cui autosviluppo e progettazione esterna si compenetrano reciprocamente. Immagine condensata di scoperte immaginative e realizzazioni materiali, i due centri congiunti che strutturano le dinamiche del mutamento, il cyborg, il quale attraversa il tempo sociologico, scandito dai ritmi intrinseci al potenziamento della comunicazione, trascende i dualismi con cui per secoli si è drasticamente spiegato il mondo, superando le distinzioni antinomiche tra identità e alterità, natura e cultura, maschio e femmina, segnate da una logica speculare spesso funzionale alle pratiche di dominio sulle categorie sociali costruite come altre

Combined carbonaceous removal and nitrification with biological aerated filters
No full textThis paper describes the use of a submerged biological aerated filter (BAFs), on a pilot plant scale, in the secondary nitrification of low strength domestic wastewater. The results, obtained throughout three months of tests, confirmed the ability of BAFs to obtain simultaneous carbonaceous removal and nitrification. In fact, after a start-up period of 5 weeks, a remarkable steady state condition in the removal of suspended solids (TSS), chemical oxygen demand (COD) and nitrification was reached. For a hydraulic loading rate of 1.6 m3 m-2 h-1, the mean efficiency of the process in the removal of TSS and COD was 85% and 83% respectively. Mean concentrations in the influent flow of around 114 mgTSS/L and 140 mg COD/L were reduced to average values of below 17 mgTSS/L and 25 mgCOD/L. Secondary nitrification was achieved with a mean efficiency of 85% for a mean volumetric loads of 0.45 kgN-Namm m -3 d-1 (25°C). Through an intensive activity of nitrification, in the steady state condition, mean influent concentrations of around 12 mgN-Namm/L were reduced to average values of below 2mg N-Namm/L. The removal loading rate increased linearly with the applied loading rate for volumetric loads of up to 0.7 kgN-Nammm -3 d-1. The nitrification was not sensitive to the applied COD loads because of the low level of carbon substrate

No full textSobolev anisotropic inequalities with monomial weights
No full textWe derive some anisotropic Sobolev inequalities in Rn with a monomial weight in the general setting of rearrangement invariant spaces. Our starting point is to obtain an integral oscillation inequality in multiplicative form
Traditional food plants in Paruro province, Peru, as a biodiversity resource with a material and immaterial value
No full textUntil now, the survival of Andean crops has been due to the existence of numerous local communities which, by preserving their traditions as well as cultivating and using these species, have managed to prevent them from being lost. For these reasons, our goal is the research on the plants used as food in Andean tradition of Paruro province in Peru. All information was gathered through consented semistructured interviews (ethnobotanical questionnaire) with people who still use traditional food plants. We recorded the use of 115 food species belonging to
55 families, mainly Asteraceae, Chenopodiaceae, Amaranthaceae, Cactaceae, Fabaceae. Several plants have been reported in literature because of nutritional or isolated components; for others no bibliographic data are available. Parts used are mainly leaves, in preparation of salads or for soups; fruits generally are used fresh. Tubers and bulbs have a great importance in the diet. A relatively high number of species are used as condiment and flavouring agents. Data recovered can be regarded
as a biodiversity resource with a material and immaterial value
