A possible answer to this problem is the emplacement of phase change materials (PCM), thereby increasing the thermal mass of a building. These materials change their state of aggregation within a defined temperature range. Useful PCM for buildings show a phase transition from solid to liquid and vice versa. The thermal mass of the materials is increased by the latent heat. A modified gypsum plaster and a salt mixture were chosen as two materials for the study of their impact on room temperature reduction. For realistic investigations, test rooms were erected where measurements were carried out under different conditions such as temporary air change, alternate internal heat gains or clouding. The experimental data was finally reproduced by dint of a mathematical model.

Il tragico òikos dei villaggi di fondazione del fascismo JF - Città di fondazione e Plantatio Ecclesiae N2 - La prima edizione di questo testo è apparsa − in una versione più ridotta −, nel volume: Pasquale Culotta, Giuliano Gresleri, Glauco Gresleri (a cura di), Città di fondazione e “Plantatio Ecclesiae”, Compositori, Bologna 2007, pp. 214-236. Un nutrito pool nazionale, specializzato sulle “Città di fondazione”, in Italia e nelle sue ex-colonie, si è misurato sul tema con una complessa storiografia interdisciplinare, che poneva al centro della sua diagnosi una connotazione teologico-ecumenica – la Plantatio Ecclesiae, appunto – della fenomenologia urbana della fundatio.

T1 - How odgcrnwi becomes crowding: Stimulus-specific learning reduces crowding JF - Journal of Vision N2 - Processes underlying crowding in visual letter recognition were examined by investigating effects of training. Experiment 1 revealed that training reduces crowding mainly for trained strings. This was corroborated in Experiment 2, where no training effects were obvious after 3 days of training when strings changed from trial to trial. Experiment 3 specified that after a short amount of training, learning effects remained specific to trained strings and also to the trained retinal eccentricity and the interletter spacing used in training. Transfer to other than trained conditions was observed only after further training. Experiment 4 showed that transfer occurred earlier when words were used as stimuli. These results thus demonstrate that part of crowding results from the absence of higher level representations of the stimulus. Such representations can be acquired through learning visual properties of the stimulus.
