1. Micronutrientes e metais pesados em fosfogesso – acúmulo, mobilidade e fator de transferência em latossolos de cerrado / Environmental evaluation on the use of the residue from the processing of phosphate rock in soils of Cerrado
O sulfato de cálcio dihidratado (CaSO4.2H2O), fosfogesso, também denominado de gesso agrícola, é um dos principais resíduos gerados na produção de fertilizantes fosfatados por meio do processo de solubilização da rocha fosfática com ácido sulfúrico. A taxa de geração é de ,aproximadamente, 4,8 t para cada tonelada de ácido fosfórico produzid

2. Fired products of Cr-smectite clays in nitrogen
The products of Cr-smectite clays heated to 1350 ° C in nitrogen were evaluated by X-ray diffraction and chemical analysis. Cr-smectite clays were prepared at room temperature by contact between smectite clays and Cr species contained in OH-Cr solutions. The Cr species were prepared using chromium nitrate solution by addition of NaOH solution with OH/Cr = 2

4. Structure of Met30 variant of transthyretin and its amyloidogenic implications.
Familial amyloidotic polyneuropathy (FAP) is an autosomal dominant hereditary type of lethal amyloidosis involving single (or double) amino acid substitutions in the amyloidogenic protein transthyretin (TTR). The most common type of FAP (Type I, or Portuguese) is characterized by a Val-->Met substitution at position 30. The Met30 variant of TTR has been prod

5. Two-dimensional crystallization of Escherichia coli-expressed bacteriorhodopsin and its D96N variant: high resolution structural studies in projection.
Highly ordered two-dimensional (2-D) crystals of Escherichia coli-expressed bacteriorhodopsin analog (e-bR) and its D96N variant (e-D96N) reconstituted in Halobacterium halobium lipids have been obtained by starting with the opsin protein purified in the denaturing detergent sodium dodecyl sulfate. These crystals embedded in glucose show electron diffraction
