A radioisotope method for measuring regional blood flow in the intestine of the dog in vivo has been favorably compared with measurement by timed collection of total venous outflow. The necessary conditions are a continuous measure of arterial concentration and cumulative regional concentration of radioisotope, an experimentally definable region, and temporary complete retention of tracer. The derivation of the relations used suggests additional applications of the method to other regions of the body.

Internal migration has been decisive in the process of rapid urbanization that has occurred throughout Brazil in recent decades. The usual explanation for this movement references poverty and the lack of job opportunities in the northeast combined with the concentration of industries in the southeast, mainly in the state of São Paulo. A process of spatial deconcentration has occurred since the 1970s. Internal migration is no longer predominantly a rural-to-urban phenomenon. Demographic growth has decreased in the Brazilian regions, due to diminishing fertility rates and changes in migration patterns. The new migration patterns are characterized by a relative decline in the number of people on the move. The decrease in population flows seems to indicate the disruption of networks between some locations. Current migrants tend to be more qualified than in the past; this characteristic contributes to decentralized development.

ABSTRACT Charcoal has an economic, social and environmental importance, because in addition to being a source of energy, it generates employment and income in the rural environment. Therefore, knowing your market is fundamental for the decision-making of those segments that depend on this raw material. This work analyzed the regional concentration of charcoal production in the state of Paraíba, Brazil, from 1994 to 2016. The data used to measure the regional production concentration (in tons) of native Paraíba charcoal were obtained from the Brazilian Institute of Geography and Statistics (IBGE) from 1994 to 2016. The indicators used were the Concentration Ratio [CR(k)], the Herfindahl-Hirschman Index (HHI), Theil's entropy index (E) and the Gini Index (G). The main results show that the mesorregions of Borborema and Sertão Paraibano present concentrations in charcoal production from Paraíba. The CR(k) of the municipalities had a low to moderately low concentration and a moderately high to a high concentration for the microregions; the HHI and E showed deconcentration tendencies from competitive markets; the G showed strong to very strong inequality for the municipalities and microregions on average. It is concluded that the concentration of charcoal production at regional levels is not concentrated, even though it presents a moderate concentration in the partial indices [CR(k)] for the Paraíba microregions.

Zuiderzee towns in the Baltic. ‘Vitten’ and ‘Vögte’ – Space and urban representatives in late-medieval ScaniaThe Scania peninsula in the southwest of present-day Sweden was one of the most important trading centres of medieval Northern Europe due to the seasonal presence of immense swarms of herring which attracted large numbers of fishermen and traders. Streching back from the beach of Scania were the so-called vitten, which the traders, grouped by region or city, held as their own, legally autonomous trade settlements, from the Danish King. Initially, these were seasonal trading colonies that were occupied only for the duration of the fair, which began in August and ended in November. In the late Middle Ages the vitten developed into miniature towns, modest off-shoots from the traders‘ mother city. The presence on a small peninsula (c 50 km2) of so many fishermen and merchants who did business together and came from different cities could easily have led to tensions and conflict. What was the relationship between the spatial arrangement of the vitten at Scania and the urban representatives of the vitten, the so-called vögte or governors? This question is addressed by focusing on the vitten of the Zuiderzee towns. Their vitten, among which were numbered those of eastern Zuiderzee cities like Kampen and Zutphen as well as those of western cities like Amsterdam, Brielle and Zierikzee, were part of the Hanse. However, the vitten of these cities have been virtually neglected in historiography. The territorial or local-topographical development of these vitten was characterized by regional concentration: the Zuiderzee vitten were located close or adjacent to one another. The new vitten of Zierikzee and Amsterdam bordered on that of Kampen. Traders from cities and towns without their own vitte were housed in a vitte of a neighboring city: those of Deventer and Zwolle, for instance, in the vitte of  Kampen, those of Enkhuizen and Wieringen in the Amsterdam vitte and those from Schouwen island in the vitte of Zierikzee. The vitten of the eastern Zuiderzee towns were founded at the beginning of the fourteenth century, that is on average half a century earlier than those of the western Zuiderzee towns. The count of Holland and Zealand initially appointed the Zierikzee vogt or governor for all his subjects. Later on, the cities in his counties then had their own governors, first appointed by the count, later by the city (with or without the count‘s approval). The development of the representation of Holland and Zeeland towns in Scania differs from what was characteristic of the eastern Zuiderzee towns. Neither the Count /Duke of Guelders nor the bishop of Utrecht (as overlord of the Oversticht) attempted to interfere with the individual towns‘ governors or the vitten. The trend towards territorialisation in Scania was unmistakable. Although foreign traders, by reason of their origins, were subject to the jurisdiction of their mother city (the personality principle), a fact reflected in the responsibility of the vogt for the citizens in question, they were also increasingly spatially limited in Scania. This was a consequence of the limited space available, of the pursuit of control over one’s own community, and of the goal of allowing different urban groups to live together peaceably, prevent conflicts and guarantee the conduct of international trade. In this way the vitten, in particular those of the Zuiderzee towns that were further away from their mother cities, can be understood as urban colonies overseas.
