Gibson once suggested that his ecological approach could provide architecture and design with a new theoretical basis. Erik Rietveld takes up this suggestion—the concept of affordances figures prominently not only in his philosophical and scientific work but also in the design practices he is engaged in. However, as Gibson introduced affordances as a functional concept, it seems ill-suited to capture the many dimensions of our lived experience of the (manufactured) environment. Can the concept of affordances also take on the expressive and aesthetic qualities of artifacts and buildings?

This paper touches upon the problems of development and illumination of small Russian towns located on the banks of rivers and water storage basins (as exemplified by master’s theses). These problems lie on the plane of preservation and effective use of architectural, historical, and cultural heritage of towns, their unusual aura and colour. In the experimental project of town development based on the town of Yurievets situated on the bank of Volga water storage basin, the authors propose an architectural-spatial functional concept of filling up the town territory with the ideas on original colour and light design in the evening and at night.

Proximal Intestine

This study quantitatively evaluated the characteristics of the aboral propagation of the canine migrating motor complex (MMC). Five conscious dogs were implanted with extraluminal force transducers along the small intestine. After constructing a 30-cm Thirty-Vella loop of jejunum, 56 of 91 activity fronts were outside the tolerance limits for propagation from the proximal intestine to the loop established in the same dogs before operation. Similarly, 44 of 109 activity fronts were outside the tolerance limits for propagation from the loop to the distal intestine. After surgery, the propagation time from the proximal jejunum to the loop was significantly increased, and activity fronts were observed to originate in the loop and in the intestine distal to the anastomosis. Our study indicates that the hypothesis that extrinsic nerves alone control the migration of the MMC is incomplete. We suggest that the extrinsic and the intrinsic innervation of the gastrointestinal tract are both required for the precise pattern of the migration of the MMC.

Cardiac Nerves

Recently it has been suggested that the parasympathetic innervation of the ventricles is by way of postganglionic axones that emanate from ganglion cells in the atria, reaching the ventricles by traversing the atrioventricular (AV) groove. We designed a series of experiments to test this hypothesis. Phenol (89%) was applied to the AV groove and surrounding 5 mm of epicardium in 21 dogs on cardiopulmonary bypass. The effects of intracoronary acetylcholine (ACh; 1-5 micrograms) and intracoronary nicotine (NIC; 25–100 micrograms) on cardiac isovolumic pressures were evaluated after beta-blockade. In another series of experiments, eight dogs were exposed to phenol in the same way and allowed to recover for 7–10 days. Atrial and ventricular responses to NIC were unaffected by phenol application to the AV groove in the acute animals when compared with application of saline alone. However, in the chronic animals, pretreatment with phenol 7–10 days previously reduced the ventricular responses to NIC by 70% while leaving the atrial responses intact. These data indicate that the intrinsic cardiac nerves (ICN) of the canine ventricles consist primarily of postganglionic parasympathetic axones which arise from supraventricular ganglia and cross the AV groove.
