1. CHARACTERISATION OF ASYMMETRIC ALUMINA HOLLOW FIBRES: APPLICATION FOR HYDROGEN PERMEATION IN COMPOSITE MEMBRANES
Abstract Asymmetric alumina hollow fibres produced by the phase inversion/sintering method present advantages in that high area/volume ratios and low mass transfer resistances are achieved due to the geometric configuration and the pore size distribution, respectively. Here we characterise hollow fibres that were prepared with different internal coagulants a

2. Estudo da permeação de hidrogênio em reator com membrana de paládio: modelagem matemática e simulação computacional
Hydrogen is the simplest and most common element in the universe. Currently, some industries use hydrogen to refine oil, and to produce ammonia and methanol. Since the combustion of hydrogen produces only water and energy, it is considered to be viable and environmentally safe. Most of the hydrogen produced in industrial scale is by the steam reforming proce

3. DETERMINATION OF SN IN HUMAN MILK BY GRAPHITE FURNACE ATOMIC ABSORPTION SPECTROMETRY / DETERMINAÇÃO DE SN EM LEITE HUMANO POR ESPECTROMETRIA DE ABSORÇÃO ATÔMICA NO FORNO DE GRAFITE
Tin is a metal of natural occurrence which is mainly extracted from the mineral cassiterite, SnO2. Tin may be released to the atmosphere from both natural and anthropogenic sources. In nature, it occurs in both inorganic and organic forms, and the shorter the organic chain associated to the metal, the higher the toxicity of the compound. Organotin compounds

4. Modelagem e simulação da operação de um reator de leito fixo catalitico envolto em membrana permseletiva / Modeling and simulation of fixed bed reactor wrapped with permselective membranes
Styrene is an important monomer in the manufacture of thermoplastic and synthetic rubbers. Most of the production is based on the catalytic dehydrogenation of ethylbenzene. The increase of the styrene productivity can be reached using permselectives membranes for hydrogen removal, suppressing the reversible and secondary reactions. This work presents the sim

5. Electron Microscopy of a Strain of Bordetella bronchiseptica
A strain of Bordetella bronchiseptica that had been isolated from a rat hepatoma cell culture was investigated by means of electron microscopy. Bacteria were examined after (i) negative staining with phosphotungstate or uranyl acetate, (ii) metal shadowing with platinum-palladium, and (iii) fixation with glutaraldehyde followed by embedding, sectioning, and
