Art dĂ©co e indĂșstria: Brasil, dĂ©cadas de 1930 e 1940
Este artigo analisa as caracterĂsticas assumidas pela arquitetura de tendĂȘncia art dĂ©co em construçÔes ligadas Ă indĂșstria - moradias, igrejas, escolas, clubes, fĂĄbricas etc. - erguidas no Brasil nas dĂ©cadas de 1930 e 1940, investigando o repertĂłrio formal utilizado em diferentes tipologias. Faz uma anĂĄlise mais detalhada das construçÔes criadas pela Companhia Industrial Fiação de Tecidos Goyanna, em Pernambuco, no perĂodo entre 1937 e o final da dĂ©cada de 1940. Trata-se de um conjunto notĂĄvel pela unidade formal, vinculada Ă linguagem art dĂ©co, e pelo emprego de soluçÔes inovadoras em termos de forma e de programa.The aim of this article is to analyze the characteristics of Art Deco tendencies in buildings related to the industry - as houses, churches, schools, clubs, plants etc - in Brazil during the 1930s and 1940s. It studies the formal repertory used in different types of construction and develops a more detailed analysis of a complex of constructions by the firm Companhia Industrial Fiação de Tecidos Goyanna, in the state of Pernambuco, built during the period between 1937 and the end of 1940s. The presented group of constructions is notable for the formal coherence, associated with the Art Deco language, and for the use of innovative program and form solutions

Planck Early Results XVIII: The power spectrum of cosmic infrared background anisotropies
Using Planck maps of six regions of low Galactic dust emission with a total area of about 140 deg2, we determine the angular power spectra of
cosmic infrared background (CIB) anisotropies from multipole â = 200 to â = 2000 at 217, 353, 545 and 857 GHz. We use 21-cm observations of
Hi as a tracer of thermal dust emission to reduce the already low level of Galactic dust emission and use the 143 GHz Planck maps in these fields
to clean out cosmic microwave background anisotropies. Both of these cleaning processes are necessary to avoid significant contamination of the
CIB signal. We measure correlated CIB structure across frequencies. As expected, the correlation decreases with increasing frequency separation,
because the contribution of high-redshift galaxies to CIB anisotropies increases with wavelengths. We find no significant difference between the
frequency spectrum of the CIB anisotropies and the CIB mean, with âI/I=15% from 217 to 857 GHz. In terms of clustering properties, the
Planck data alone rule out the linear scale- and redshift-independent bias model. Non-linear corrections are significant. Consequently, we develop
an alternative model that couples a dusty galaxy, parametric evolution model with a simple halo-model approach. It provides an excellent fit to
the measured anisotropy angular power spectra and suggests that a different halo occupation distribution is required at each frequency, which
is consistent with our expectation that each frequency is dominated by contributions from different redshifts. In our best-fit model, half of the
anisotropy power at â=2000 comes from redshifts z 2 at 353
and 217 GHz, respectively
