Architettura, emozioni, empatia
Come scritto nella presentazione delle curatrici (P. Gregory, G. Scotto) del n. 2/2024 della Rivista "Pólemos. Materiali di filosofia e critica sociale", il rapporto fra il corpo umano e il luogo che lo ospita non è assimilabile al modo in cui un qualsiasi corpo inerte è collocato nello spazio. Il corpo vivente non solo si rapporta allo spazio in senso attivo, in quanto può modificarne l’assetto, l’ordine, la configurazione, ma ne è sempre colpito e coinvolto, anche in assenza di una sua razionalizzazione. Con riferimento agli sviluppi più recenti dell'estetica, della filosofia e delle scienze cognitive (con particolare riguardo alle neuroscienze cognitive e affettive), i contributi raccolti indagano sia il piano teorico sia alcune opere realizzate, al cui centro è il rapporto fra corpo vissuto e spazio, fra emozioni, empatia e forme dell'architettura

Reduction of cutaneous blood flow in cold fingers.
Blood flow to fingers is reduced during cold exposure. This is generally attributed to vasoconstriction. We tested the hypothesis that increased blood viscosity, not vasoconstriction, accounts for reductions of cutaneous flow after fingers cool. Blood viscosity was higher at 10 degree C than at 27 degree C and independent of hematocrit at low shear rates. The increase of finger vascular resistance may be due to increased vascular hindrance early in cold exposure (< 15 min) and is more likely due to increased viscosity after 20-30 min, a factor that may dominate the peripheral microcirculaton during prolonged cold exposure
Corpo e presenza in Bernard Noel e Yves Bonnefoy
L'articolo, incentrato su due dei maggiori poeti francesi del Secondo Novecento, si propone d’indagare due aspetti della loro poetica, che, pur nella evidente diversità dei rispettivi loro percorsi e orientamenti, si configurano per entrambi come costanti tematiche alla luce delle quali misurare il coinvolgimento fisico e personale del poeta nella creazione.
Nel solco di Bataille, Artaud e Blanchot, Bernard Noël (1930), fin dagli esordi di Extraits du corps mette in atto una gnoseologia lirica fondata sull’esigenza catartica di «ricominciare il corpo» e di dotarsi di uno sguardo capace di «dar vita al mondo nei nostri occhi» creando le immagini che il soggetto esperisce al fine di sottrarsi ad ogni «sensura», in quanto «privazione di senso».
Yves Bonnefoy (1923-2016), inizialmente segnato dal surrealismo, sviluppa un pensiero poetico fortemente marcato dalla filosofia dell’essere e dall’arte barocca, al centro del quale si colloca la lotta contro il dualismo platonico del concetto, a favore di una poesia che si voglia relazione con la natura e con il mondo e ricerca di una felicità intra-mondana sulla terra che rifugga dalla tentazione gnostica.
Se in Noël prevale una parola erotica e sensuale fortemente fisicizzata e in Bonnefoy invece una visione più arcadico-apollinea dell’amore come agape, tuttavia è possibile mostrare, specie negli esiti più recenti della loro ricerca, una convergenza relativa, da un lato all’importanza del corpo come luogo della percezione del mondo nell’immediatezza sensibile della relazione, e dall’altro della presenza quale desiderio d’essere che si fondi, anche attraverso il comune sguardo critico sull’arte, sull’evidenza di appartenere all’hic et nunc del mondo in ciò che Bonnefoy chiama l’heure présente e Noël le jardin d’encre
The use of biochar as strategy to mitigate the NH3 emissions during the digestate storage
Introduction
The environmental impact of manure storage in terms of ammonia (NH3) emissions has recently become a subject of greater interest. In this context, a common mitigation strategy is to cover the surface of the storage tank with a variety of floating materials, including straw, sawdust, clay, and oil. A common issue associated with the use of covers is the financial cost and the necessity for maintenance over time. Biochar has recently been investigated as an alternative to floating covers due to its durability and hydrophobicity.
This work examines the potential of biochar as a floating cover to reduce NH3 emissions, providing an overview of different biochar applications, in terms of dosage and biochar characteristics.
Material and Methods
The simulation of digestate storage was conducted in a climate-controlled room, utilising 5 L glass vessels. Buffalo digestate was collected from an anaerobic digestion plant in Southern Italy and analysed according to Apha (2005). First and second tests were performed with a commercial biochar, produced via pyrolysis (30 minutes) at 550 °C, using as feedstock mixed wood chips from Piedmont. Three different biochar applications methods were compared: 140 g (2 cm layer) and 70 g of biochar applied on the surface, and 140 g of biochar mixed with the digestate. In the third test, biochar was produced in the laboratory, using two different pyrolysis temperatures: 285 and 450 °C. Wood chips of Poplar tree (Populus nigra) were used as feedstock. A 2 cm layer was adopted. NH3 emissions were monitored by means of the dynamic chamber technique, as described by Scotto di Perta et al. (2022). After tests, N adsorbed during the manure storage tests by the biochar was evaluated, as described by Scotto di Perta et al. (2024).
Results and Discussion
Biochar dosage and application method When the biochar layer is floating and compact, it reduces 78% NH3 released into the atmosphere with 2 cm layer thickness, since it introduces an additional resistance to the gas transfer. This aspect is even more effective than the N-NH4 + adsorption. Moreover, the results show that a 43% reduction in NH3 emissions can be achieved by using biochar as a floating cover of 2 cm rather than its mixing with digestate (Scotto di Perta et al., 2024).
Pyrolysis temperature
Biochar obtained at 450°C was characterized by the higher specific surface of the biochar, this can explain its higher N-NH4 + adsorption (2.86 ± 0.75 mg/gchar), since the possibility of interaction of the biochar with the ions present in the solution increases. On the other hand, the greater adsorption capacity of biochar at 450°C does not seem to have played a relevant role in the reduction of NH3 emissions, confirming that the "lid" action is prevailing in limiting the gaseous exchange. Biochar produced at 285 °C is more hydrophobic and durable, thus it emitted 42% less than the other one (Scotto di Perta et al., 2022).
Conclusions
In conclusion, the results demonstrate that the application of biochar on the manure surface is an effective method for reducing NH3 emission by up to 78%, with a 2 cm layer thickness. Furthermore, biochar functions as an adsorbent material. Biochar produced at a lower temperature resulted in a greater degree of hydrophilicity thus, a more durable product when applied as a floating cover

Place navigation in rats guided by a vestibular and kinesthetic orienting gradient.
The role of the slope of terrain in orientation was examined in rats trained to find, among 4 equidistant feeders, the 1 located in the upper left quadrant of a 10% tilted arena (1-m radius). Rats started from the center in light and with randomly changing slope direction reached the correct goal in 90% of 1st choices after 29 sessions. The same rats maintained 83% correct choices when the experiment was conducted in darkness. On a horizontal arena, their performance became random. After training, successful navigation was also observed (71% correct 1st choices) when the rats were started from different points at about 30 cm from the wall. This finding suggests that the slope of terrain may be used to establish a cognitive map based primarily on kinesthetic and vestibular signals. The flexibility of such a map seems to be rather limited, however, because changing the goal position with respect to inclination requires prolonged retraining
