Case studies from Hellenistic and imperial Corinth and Ephesus demonstrate the ways in which springs and fountains were used to honour forces of nature, commemorate mythological figures and events, and strengthen, or even invent, local traditions. Famous for its natural water supply, Corinth capitalized on storied springs, both before and after its destruction and refoundation as a Roman colony. The fountains of Peirene and Glauce demonstrate different strategies for connecting past and present and establishing authority by the manipulation of architectural form and the selective retelling of stories. At Ephesus, Hellenistic and Roman fountains celebrated local nature and myth with increasingly extravagant architecture, statuary, and water displays. This chapter focuses on a series of fountains that featured the founding hero Androclus, from a monument erected in his honour to great facade fountains in which he was one of many figures communicating Ephesian identity and pride.

We address the basic question in discrete Morse theory of combining discrete gradient fields that are partially defined on subsets of the given complex. This is a well-posed question when the discrete gradient field V is generated using a fixed algorithm which has a local nature. One example is ProcessLowerStars, a widely used algorithm for computing persistent homology associated to a grey-scale image in 2D or 3D. While the algorithm for V may be inherently local, being computed within stars of vertices and so embarrassingly parallelizable, in practical use, it is natural to want to distribute the computation over patches Pi, apply the chosen algorithm to compute the fields Vi associated to each patch, and then assemble the ambient field V from these. Simply merging the fields from the patches, even when that makes sense, gives a wrong answer. We develop both very general merging procedures and leaner versions designed for specific, easy-to-arrange covering patterns.

For the first time, materials of such settlements of the East Trypillia culture as Trostyanchyk, Onopriyivka І are published. Despite approximately the same quantitative ratio, even at first glance, the materials of these two leaflets differ significantly from each other. The Trostyanchyk complex is actually blade-type: blades prevail both among production waste and among the tool kit. Flakes and tools on them dominate in Onopriyivka. If the Trostyanchyk complex can be regarded as "classic" in terms of the tool kit: retouched blades, end-scrapers, sickle inserts, perforators on blades, etc., then the Onopriyivka complex looks more primitive: retouched flakes, notched tools and scrapers on flakes, and others. In Onopriyivka, unlike Trostyanchyk, finds of weapons are completely absent. Products from Onopriyivka are made mainly of local raw materials, while in Trostyanchyk there are approximately equal parts of products from local and imported raw materials, and products from local flint are made as carefully as products from Volyn flint. At the same time, in both cases we can confidently speak of the local nature of production. This is evidenced by both the use of local flint raw material and the specific items present in both collections. In Trostyanchyk, as already mentioned, a hammerstone was found, in Onopriyivka — core-like fragments and chips of modify of cores. Such differences can be explained by both territorial and chronological discrepancies. Onopriyivka I is earlier, refers to the end of stage ВІ, Trostyanchyk — to the end of stage ВІІ. Trostyanchyk is located on the Southern Bug, Onopriyivka — in the Bugo-Dnieper interfluve. Although, perhaps, this situation is explained by the unevenness of the study of these sites. In addition, materials from the Vladyslavchyk settlement are published for the first time. Based on their analysis, using analogies from related and synchronous sites, the author tried to identify the features of the East Trypillia lithic industry in the Bug-Dnieper rivers interfluve. As it turned out, at the modern level, the identification of such features is not possible. The materials of the East Trypillia culture of the region are, on the whole, more similar to the materials of the settlements of the West Trypillia culture, than to related sites on the Southern Bug.

Abstract Using time-sequence vector magnetic field observation from Helioseismic and Magnetic Imager, we examined the connection of non-neutralized currents and the observed activity in 20 solar active regions (ARs). The net current in a given magnetic polarity is algebraic sum of direct current (DC) and return current (RC) and the ratio |DC/RC| is a measure of degree of net current neutralization (NCN). In the emerging ARs, the non-neutrality of these currents builds with the onset of flux emergence, following the relaxation to neutrality during the separation motion of bipolar regions. Accordingly, some emerging ARs are source regions of CMEs occurring at the time of higher level non-neutrality. ARs in the post-emergence phase can be CME productive provided they have interacting bipolar regions with converging and shearing motions. In these cases, the net current evolves with higher level (>1.3) of non-neutrality. Differently, the |DC/RC| in flaring and quiet ARs vary near unity. In all the AR samples, the |DC/RC| is higher for chiral current density than that for vertical current density. Owing to the fact that the non-neutralized currents arise in the vicinity of sheared polarity-inversion-lines (SPILs), the profiles of the total length of SPIL segments and the degree of NCN follow each other with a positive correlation. We find that the SPIL is localized as small segments in flaring-ARs, whereas it is long continuous in CME-producing ARs. These observations demonstrate the dividing line between the CMEs and flares with the difference being in global or local nature of magnetic shear in the AR that reflected in non-neutralized currents.

With the use of a strain-gauge plethysmograph, the effect of a brief (0.3 sec) contraction of the forearm muscles on forearm blood flow has been studied in eight healthy adults. An increase in flow due to dilatation of the muscle vessels could be detected within a second after the completion of the contraction. This increase was proportional to the strength of the contraction. The blood flow was maximal immediately and decreased rapidly. A second contraction of the same magnitude made during the period of increased flow caused an additional increase in flow. The maximal increase in flow caused by a strong brief contraction was only about 25% of that recorded after strong repeated rhythmic contractions or a sustained contraction. Cervical sympathectomy did not change these findings, indicating the local nature of the response. Since breathing oxygen failed to reduce the dilatation for a given strength of contraction, it is unlikely that oxygen lack was the stimulus for vasodilatation. The oxygen saturation of blood that drained the muscles could not be determined accurately immediately after contraction because at this time, muscle venous blood was contaminated by venous blood from the skin. exercise-induced vasodilatation; local mechanism of vasodilatation; venous O2 saturation during muscle contraction; brachial arterial pressure during vasodilatation; speed of muscle vasodilatation Submitted on May 8, 1963

Prominence seismology is a rapidly developing topic which seeks to infer the internal structure and properties of solar prominences from the study of their oscillations. An extense observational background about oscillations in quiescent solar prominences has been gathered during the last 70 years. These observations point out the existence of two different types of oscillations: flare-induced oscillations (winking filaments) which affect the whole prominence and are of large amplitude and small amplitude oscillations which seem to be of local nature. From the theoretical point of view, few models have been set up to explain the phenomenon of winking filaments while, on the contrary, for small amplitude oscillations a large number of models trying to explain the observed features have been proposed. Here, recent theoretical and observational developments on both types of oscillations are reviewed, and suggestions about future research topics which should provide us with a more in-depth knowledge of solar prominences are made.
