The Ultrafiltration Performance of Cellulose Acetate Asymmetric Membranes: A New Perspective on the Correlation with the Infrared Spectra

Integral asymmetric cellulose acetate (CA) membranes were casted by phase-inversion with formamide varying content - 22, 30 and 34% - as pore promoter. These membranes, CA-22, CA-30 and CA-34, were analyzed by infrared spectroscopy in attenuated total reflection mode (ATR-FTIR) to investigate the porous membrane matrix influence on the polymer/water/solute interactions and the selective ultrafi...

A new species of Canace Haliday from Portugal, with a revised key to species (Diptera: Canacidae: Canacinae).

A new species of Canace Haliday, in Curtis, 1837 from Portugal is described. This species, related to C. actites Mathis, 1982, is known so far from a single maritime locality near Lisbon. A key to species of the genus is also provided.

An Empirical Comparison between Grade of Membership and Principal Component Analysis

t is the purpose of this paper to contribute to the discussion initiated byWachter about the parallelism between principal component (PC) and atypological grade of membership (GoM) analysis. The author testedempirically the close relationship between both analysis in a lowdimensional framework comprising up to nine dichotomous variables and twotypologies. Our contribution to the subject is also...
