1. Substrates and containers for the development of Brassica pekinensis L. seedlings
ABSTRACT The aim of this study was to evaluate the development of Chinguensai (Brassica pekinensis L.) seedlings, under different formulations of substrates and sizes of containers, in Fortaleza, Ceará. For this, two studies were conducted in factorial design with randomized blocks and four replicates. The first study was conducted in a factorial (4 × 4) d

2. AVALIAÇÃO DE PROPRIEDADES FÍSICAS E QUÍMICAS DE ELETRODEPÓSITOS DE Ni-W-P OBTIDOS EM CÉLULA DE HULL
Ni–W–P electrodeposits were synthesized in a Hull cell in order to simulate the obtainment under industrial conditions. Complete coverage of panels was accomplished by applying total currents of 1.0 and 2.0 A. Panels obtained with a current of 1.0 A appeared brighter. The best compositional uniformities, as determined by Energy Dispersive Spectrometer (E

3. Evaluation of oat hull hemicellulosic hydrolysate fermentability employing Pichia stipitis
Oat hull hemicellulosic hydrolysate obtained by diluted acid hydrolysis was employed as fermentation medium for Pichia stipitis cultivation. A comparison between the use of treated hydrolysate with 1% activated charcoal to reduce the toxic compounds generated during the hydrolysis process and untreated hydrolysate as a control was conducted. In the cultures

4. Electrodeposition of CoNi and CoNiMo magnetic alloys thin films and nanowires / Eletrodeposição de filmes finos e materiais nanoestruturados das ligas magnéticas cobalto-níquel e cobalto-níquel-molibdênio
Este trabalho trata do estudo da eletrodeposição de filmes finos e nanofios magnéticos compostos de cobalto, níquel e molibdênio. Foi avaliada a influência da composição química das soluções utilizadas nas propriedades do material obtido. O uso de uma célula de Hull com eletrodo cilíndrico rotativo permitiu também que fosse estudado com mais de

5. Estudo eletroquímico de um novo banho galvânico de zinco alcalino livre de cianetos
A systematic electrochemical study of a novel cyanide free galvanic plating solution of alkaline zinc is presented. Cell Hull tests and potentiodynamic linear polarization measurements were carried out to evaluate the influence of operational parameters, such as concentration, current efficiency and degradation of additives. The stability of the bath was ass

6. Contribuição ao estudo de aproveitamento de residuos lignocelulosicos
Chrysonilia sitophila (TFB 27441) is a fungus which is able to convert very efficiently rice hull in single cell protein. The yield and/or the quality of the single cell protein were improved by chemical or photochemical pre-treatment alone. The photochemical pre-treatments studied were irradia- tion at wavelengths higher than 254 nm and 300 nm and the chemi

7. The α-Specific Cell Identity Factor Sxi1α Is Not Required for Virulence of Cryptococcus neoformans
Cryptococcus neoformans is a human fungal pathogen that has two mating types (a and α). Experiments have shown that in some backgrounds α strains are more virulent than a strains. Our studies reveal that the only known α-specific factor, SXI1α, is not necessary for virulence.

8. Cell identity and sexual development in Cryptococcus neoformans are controlled by the mating-type-specific homeodomain protein Sxi1α
Virulence in the human fungal pathogen Cryptococcus neoformans is associated with the α mating type. Studies to identify the properties of α cells that enhance pathogenesis have led to the identification of a mating-type locus of unusually large size and distinct architecture. Here, we demonstrate that the previously identified MATα components are insuffi

9. Virulence Properties of Escherichia coli 83972, a Prototype Strain Associated with Asymptomatic Bacteriuria
Little is known about bacteria associated with asymptomatic bacteriuria (ABU) with regard to urinary tract colonization mechanisms. In this study, virulence properties of Escherichia coli 83972, a strain that was isolated from a clinical ABU episode, were examined. The genetic potential for expression of P and type 1 pili was demonstrated, and DNA sequences

10. Preparation and evaluation of two microbiological media from shrimp heads and hulls.
Two peptones were extracted from raw shrimp waste after autolytic digestion. Digests were derived from shrimp heads and shrimp hulls, both of which are by-products of the shrimp processing industry. Digests were evaluated for suitability in supporting growth of microorganisms by measuring the total cell mass produced by five genera of bacteria and five gener

11. Sensitivity of Intracellular Bacteriophage λ to Colicin CA42-E2
Treatment of Escherichia coli K-12 infected by λ CIts857 with colicin CA42-E2 resulted in partial inhibition of the infectious process. Uninfected bacteria were killed by colicin with a probability of about five times that with which similarly treated λ-infected bacteria lose plaque-forming ability. The λ deoxyribonucleic acid (DNA), when present in a bac

12. Pulmonary epithelial cell expression of GM-CSF corrects the alveolar proteinosis in GM-CSF-deficient mice.
Mutation of the granulocyte-macrophage colony-stimulating factor (GM-CSF) gene by homologous recombination caused alveolar proteinosis in mice. To further discern the role of GM-CSF in surfactant homeostasis, the synthesis of GM-CSF was directed to the respiratory epithelium of GM-CSF-hull mutant mice (GM-/-) with a chimeric gene expressing GM-CSF under the
