Type Data

Sea level variations collected in several areas in the world have been analyzed trying to infer their non linear characteristics. Analyzed data were acquired in several sites in West and East coasts of the North American continent, in the Hawaii and Bermuda islands, representing oceanic sites, and in Adriatic sea, representing a well known basin type. Data have been analyzed through Independent Component Analysis, False Nearest Neighbours and the estimation of correlation dimension using Grasberger and Procaccia integral. Results show a clear non linear features in all the sites, characterized by second and third order Landau mode.

The 19Th Century

In debates on American immigration law, it is possible to encounter the argument that there were no laws restricting newcomers’ flow into America till the end of the 19th century. An inaccurate understanding of American immigration policy sometimes leads to the opinion that prior to the beginning of the federal immigration power, there was no immigration policy at all in America. This article describes regulations enacted by the colonies and the states, as well as activities taken by them, to control the influx of newcomers. They tried to encourage immigrants to come to America while simultaneously controlling who was coming. The idea of successful control over immigrants coming to the North American continent was rooted in restrictive laws determining who was admissible. Paupers, criminals and those with contagious diseases were undesirable. Colonial and state authorities tried to stop their influx or, at least, to lessen the danger they posed. The main goal of the presented article is to analyze and present arguments proving or neglecting the assumption that there was a lack of an immigration policy during colonial times in America.

Inuit Peoples

The Arctic part of the North American continent has seen some of the most fascinating and demanding human adaptations anywhere, culminating in those of the Inuit who live there today. This region is characterized by persistence of cold (long winters and short cool summers), permafrost (year-round frozen ground), large seasonal differences in the amount of sunlight, few or no trees, and a minimum of plant foods directly consumable by humans. To survive in this environment the Inuit peoples and their predecessors, of necessity, relied on technology and on animal resources to a greater extent than recent hunter-gatherer populations anywhere else in the world. This chapter explores the ethnographic and archaeological records of these peoples and this region to study the nature of childhood in prehistoric hunter-gatherer populations.

This paper consists of an epidemiological study of 52 cases of Q fever occurring in metropolitan Adelaide in 1957 and also a description of the results of a survey of 516 sera obtained from abattoir workers.The only case occurring outside the abattoirs was a dairy farmer who probably became infected while visiting the abattoirs. If this were so the incubation period (35 days) of his disease would have been exceptionally long.The general features of the outbreak, which lasted several months, differed from those on the North American continent in that the latter occurred explosively within a few days with very high attack rates. The situation in the Adelaide abattoirs is similar to that in Brisbane, where the disease appears to be endemic. However, unlike in Adelaide, cases are commonly recognized outside the abattoirs in Brisbane.In the abattoirs the disease affected mainly inspectors, those working on killing beef, and those working on offal. Mutton workers were not so severely affected. However, all these groups had similar incidences of low titre antibodies suggesting that in the past Q fever spread equally in all killing departments. In departments not directly associated with slaughtering the incidence both of cases in 1957 and low titre antibodies was relatively small.It was suggested that the epidemiological features of Q fever in Adelaide could be explained by the irregular appearance of animals from infected herds situated perhaps in Queensland—a known endemic area. Perhaps the appearance of such animals in the Adelaide abattoirs might be governed by meteorological conditions such that they were prevented from going to the ordinarily most convenient slaughterhouse.

Austrian Minister

On September 26, 1786, Don Francisco de Miranda, adventurer and patriot, secured a passport from the Austrian Minister in Constantinople which enabled him to continue his “grand tour” to Russia. The nature of Miranda’s subsequent visit, and the extent to which his reception at the court of Catherine II influenced Spanish and Russian policy, assumes significance in the light of events on the North American continent immediately preceding and during his stay in Russia.

The chlorophycean alga Percursaria percursa (Ulvaceae, Ulvales, Chlorophyceae), typical of marine inter-tidal zones, is reported for the first time from hypersaline springs located along the north-western shore of Lake Winnipegosis in Manitoba. Although not usually found inland, P. percursa is the dominant member of microbial mat communities that thrive in shallow pools at the outlets of hypersaline springs.
