1. Formação de filme líquido nas paredes de um lavador venturi
The study of the liquid film in the walls of a Venturi scrubber was chosen as the target of this work for representing one of the important phenomena that influence the collection efficiency of the equipment. Such efficiency decreases with the presence of the film once it has a superficial area per volume much smaller than the drops and, consequently, contri

2. Espanhol e português em contato: o atrito da L1 de imigrantes espanhóis no Brasil
The aim of this dissertation is to explore the process of attrition or language loss which i produced in the L1 of Spanish speaking adult Spaniards who are immigrants and residing in Brazil and who are proficient in Portuguese, which is, therefore, the L2, the contact language The action of the latter language plays a decisive role, since its influence over

3. Evaluacion termica, mecanica y electrica de materiales compuestos cordierita-mullita
Commercially available cordierite and mullite powders were used to obtain cordierite and cordierite-30wt% mullite materials by attrition milling, uniaxial pressing and sintering. Cordierite powders were the coarse (D50 = 1.82 mum), medium (D50 = 0.9 mum) and fine (D50 = 0.45 mum) single granulometric fractions and binary mixtures of them. Mullite powder empl

4. Observations on the primordial germ cells of bandicoots (Peramelidae, Marsupialia).
Characteristically, bandicoot primordial germ cells are large, lightly staining cells with vesicular nuclei in which the chromatin is clumped beneath the nuclear envelope. Rounded, lightly staining cells in the yolk sac wall of 9 1/2 days old embryos are tentatively identified as primordial germ cells; as they lack other primordial germ cell attributes it is

6. Distribution of Anionic Groups at the Cell Surface of Different Sporothrix schenckii Cell Types
The distribution of anionic groups at the cell surface of yeastlike forms, hyphae, and conidia of Sporothrix schenckii was studied by staining with colloidal iron hydroxide and cationized ferritin. By using colloidal iron hydroxide it was shown that the external cell wall layer of one strain (strain 1099.18) could be resolved into two reactive sublayers and
