1. Sustainable Glass Foams Produced from Glass Bottles and Tobacco Residue
In this work, discarded soda-lime-silica glass bottles and tobacco residue (after oil extraction to produce biodiesel) were prepared in different formulations to obtain glass foams. The formulated compositions were homogenized and uniaxially compacted at 40 MPa then fired at 850 ºC and 900 ºC for 60 min to investigate the effects of tobacco residue and tem

2. Efeito da temperatura e da adição de sais inorgânicos na pirólise analítica de resíduo de tabaco
Combustíveis menos poluentes e originados de fontes renováveis, como a biomassa, são alternativas energéticas. Atualmente cerca de 4000t/ano de resíduo de tabaco são geradas no Brasil e a pirólise rápida _e uma opção para se converter biomassa em combustíveis, no caso o bio-óleo, que pode ser também fonte de compostos com valor agregado. O prese

3. Proportion of organic material in standard substrate in coffee seedlings production in tubetts / Proporção de material orgânico no substrato artificial na produção de mudas de cafeeiro em tubetes
Utilization of organic materials might contribute to reduce costs of production and enhance vegetative development and quality of coffee seedlings. With the objective of evaluating the effects of the utilization of different organic materials on the standard substrate used for coffee seedlings production, (Coffe Arabic L.), an experiment was conducted at the

5. ESTUDO DA VIABILIDADE DE ADIÇÃO DE RESÍDUO DE PÓ DE FUMO À MASSA CERÂMICA / STUDY ON THE VIABILITY OF ADDITION OF TOBACCO DUST TO CERAMICS MASS
Essa pesquisa compreende o estudo da viabilidade de adição de resíduo da indústria fumageira (pó de fumo) à massa cerâmica utilizada para a fabricação de produtos cerâmicos. Dessa forma, objetiva a incorporação desse resíduo na mistura (destinação adequada) em substituição parcial da matéria-prima (economia de argila). Para essa pesquisa fo

6. Molecular localization of a redox-modulated process regulating plant mitochondrial electron transport
Using in organellar assays, we found that significant tobacco alternative oxidase (AOX) activity is dependent on both reduction of a putative regulatory disulfide bond and the presence of pyruvate, which may interact with a Cys sulfhydryl. This redox modulation and pyruvate activation thus may be important in determining the partitioning of electrons to AOX

7. A tyrosine residue in the small nuclear inclusion protein of tobacco vein mottling virus links the VPg to the viral RNA.
The identity of the amino acid residue that links the VPg of the potyvirus tobacco vein mottling virus (TVMV) to the viral RNA was determined. 32P-labeled TVMV RNA was digested with RNase A and micrococcal nuclease. The resulting 32P-labeled VPg was isolated and partially hydrolyzed with 6 N HCl at 110 degrees C for 2 h. Analysis by thin-layer electrophoresi

8. Salicylic acid activates a 48-kD MAP kinase in tobacco.
The involvement of phosphorylation/dephosphorylation in the salicylic acid (SA) signal transduction pathway leading to pathogenesis-related gene induction has previously been demonstrated using kinase and phosphatase inhibitors. Here, we show that in tobacco suspension cells, SA induced a rapid and transient activation of a 48-kD kinase that uses myelin basi

9. Nucleotide sequence of the 30K protein cistron of cowpea strain of tobacco mosaic virus.
The nucleotide sequence of cloned cDNA copies of cowpea strain of tobacco mosaic virus RNA including the 30K protein cistron was determined. The 30K protein cistron was located at residue 676-1,527 from the 3' end of the genomic RNA. The 30K protein was composed of 282 amino acid residues and was basic, similar to the 30K protein of common strain OM. However

10. Mutational analysis of tobacco etch virus polyprotein processing: cis and trans proteolytic activities of polyproteins containing the 49-kilodalton proteinase.
The genome of tobacco etch virus contains a single open reading frame with the potential to encode a 346-kilodalton (kDa) polyprotein. The large polyprotein is cleaved at several positions by a tobacco etch virus genome-encoded, 49-kDa proteinase. The locations of the 49-kDa proteinase-mediated cleavage sites flanking the 71-kDa cytoplasmic pinwheel inclusio

11. Post-translational modifications in the large subunit of ribulose bisphosphate carboxylase/oxygenase.
Two adjacent N-terminal tryptic peptides of the large subunit of ribulose bisphosphate carboxylase/oxygenase [3-phospho-D-glycerate carboxy-lyase (dimerizing), EC 4.1.1.39] from spinach, wheat, tobacco, and muskmelon were removed by limited tryptic proteolysis. Characterization by peptide sequencing, amino acid composition, and tandem mass spectrometry revea

12. Infectious in vitro transcripts from cloned cDNA of a potyvirus, tobacco vein mottling virus.
Full-length cDNA copies of tobacco vein mottling virus (TVMV) RNA were constructed downstream from bacteriophage T7 or T3 RNA polymerase promoters. The plasmids were designed to produce in vitro transcripts containing, respectively, one or two guanosine residues at the 5' terminus not derived from the TVMV sequence and a single cytidine residue at the 3' ter
