Preliminary Geomorphological Study of a Newly Discovered Dorset Culture Site on Melville Island, N.W.T.

Describes a prehistoric dwelling found at McCormick Inlet in 1962. Location of the site at 1.75 m above high water and its age, estimated at 1150-1740 yr from radiocarbon dating of moss, indicate negligible land emergence during the last one and a half millennia. Prehistoric sites recorded by other explorers on the island are also noted and mapped

The Influence of Growth Rate Upon Brain development in Rana Pipiens Tadpoles.

In the course of studies on the development of the optic tectum in the frog (Kollros, \u2753), considerable variation in the cell populations of the outermost tectal layers was noted, with some involvement of the deeper layers as well. The greatest differences appeared toward the end of metamorphosis, with cell counts in some animals being 30 to 40 per cent less than those in others. The animals with low counts were generally smaller than those with the high counts, and frequently they grew more slowly. In order to study the variations in tectal development which might be associated with variations in growth rate, the growth of tadpoles was inhibited through partial starvation and by crowding (see Rugh, \u2734), and the cell counts of the tecta of these animals were compared with those of well fed, uncrowded control animals

Drag reduction induced by superhydrophobic surfaces in turbulent pipe flow

The drag reduction induced by superhydrophobic surfaces is investigated in a turbulent pipe flow. Wetted superhydrophobic surfaces are shown to trap gas bubbles in their asperities. This stops the liquid from coming in direct contact with the wall in that location, allowing the flow to slip over the air bubbles. We consider a well-defined texture with streamwise grooves at the walls in which the gas is expected to be entrapped. This configuration is modeled with alternating no-slip and shear-free boundary conditions at the wall. With respect to the classical turbulent pipe flow, a substantial drag reduction is observed which strongly depends on the grooves’ dimension and on the solid fraction, i.e., the ratio between the solid wall surface and the total surface of the pipe’s circumference. The drag reduction is due to the mean slip velocity at the wall which increases the flow rate at a fixed pressure drop. The enforced boundary conditions also produce peculiar turbulent structures which on the contrary decrease the flow rate. The two concurrent effects provide an overall flow rate increase as demonstrated by means of the mean axial momentum balance. This equation provides the balance between the mean pressure gradient, the Reynolds stress, the mean flow rate, and the mean slip velocity contribution

Desconfiança no Heartland: explicando o "Vazio Organizacional" eurasiático por meio das relações Russo-Chinesas

The concept of Eurasia is one of the most important elements of geopolitics, dating back to the beginning of the last century, and whose development owes much to the works of geographers and political thinkers alike. Nevertheless, although comprising a big portion of the planet’s political space, this region suffers from a relative ‘organizational gap’, especially if compared with neighboring regions such as Western Europe and Southeast Asia for instance. This paper contends that the lack of an overarching political arrangement in Eurasia owes much to particular aspects of the Russia-China relationship, which encompasses Great Power aspirations and competing organizational schemesin the region. Different views about Eurasia itself, associated with a quest for leadership in regional institution-building, put both Russia and China on competitive tracks, essentially obstructing the formation of a broad political design in the broader continent. To substantiate our point, the present work applies certain concepts from historical institutionalism, whose mechanisms enabled a thorough evaluation of patterns of inception, continuation, and change of political institutions, alliances and principles affecting the Sino-Russian relationship over time, as well as its effects on Eurasia’s ‘organizational gap’ per se. O conceito de Eurásia é um dos elementos mais importantes da geopolítica, o qual remonta ao início do século passado, e cujo desenvolvimento deve muito às obras de geógrafos e de pensadores políticos. No entanto, embora englobe uma grande parte do espaço político do planeta, esta região sofre de uma relativa ‘lacuna organizacional’, especialmente se comparada com regiões vizinhas, como a Europa Ocidental e o Sudeste Asiático, por exemplo. Este artigo propõe que a falta de um arranjo político abrangente na Eurásia se deve muito a aspectos particulares da relação Rússia-China, que engloba aspirações por parte de duas Grandes Potências e esquemas organizacionais concorrentes na região. Diferentes visões sobre a própria Eurásia, associadas à busca pela liderança na construção de instituições regionais, colocaram a Rússia e a China em caminhos competitivos, essencialmente obstruindo a formação de um amplo desenho político no continente. Para substanciar nosso argumento, o presente trabalho aplica certos conceitos do institucionalismo histórico, cujos mecanismos permitiram-nos uma avaliação mais ampla dos padrões de surgimento, continuação e mudança das instituições políticas, alianças e princípios que afetaram a relação sino-russa ao longo do tempo, bem como sua efeitos na 'lacuna organizacional' da Eurásia em si
