Sedimentologia e Estratigrafia –Estudo de um terraço de Lavadores. Contri...

Sedimentological studies of the terrace of the Pedras Amarelas in Lavaores (Vila Nova de Gaia) suggest, from the bottom up and to the migration of sedimentary environments to the west, the existence of coastal intertidal sedimentation, from the river sedimentation and culminating with swampy environments/lagoon in which there is evidence periglaciation. Geochronological studies conducted by OSL and 14C dating a...

Microbial community structure of biohydrogen production process in extreme ther...

Advanced monitoring of high-rate anaerobic reactors through quantitative image ...

Four organic loading disturbances were performed in lab-scale EGSB reactors fed with ethanol. In load disturbance 1 (LD1) and 2 (LD2), the organic loading rate (OLR) was increased between 5 and 18.5 kg COD m-3 day-1, through the influent ethanol concentration increase, and the hydraulic retention time decrease from 7.8 to 2.5 h, respectively. Load disturbances 3 (LD3) and 4 (LD4) were applied by increasing the ...

Evolution of the composition in fatty acids of the dorsal subcutaneous adipose ...

The present work studied the evolution of fatty acid composition in the dorsal subcutaneous fat of free-range Alentejano pigs fed on pasture and acorns. Twenty pigs with a body weight (BW) of ~90 kg were placed in a 2 ha pasture (Lolium westerwoldium and Trifolium incarnatum) and fed daily with 4 kg of acorns. Animals were submitted to biopsies near tail insertion with ~90, ~100, and at slaughter, ~110 kg BW. T...

Microbial communities shifts in dark fermentative H2 production at mesophilic, ...

Hydrogen is foreseen as a viable CO2-neutral alternative to fossil fuels for generation of energy. Production of H2 from wastes/wastewaters is possible as this is one of the main products resulting from anaerobic fermentation of organic compounds. If hydrogenotrophic methanogens are suppressed, H2-rich biogas can be recovered from anaerobic reactors. In order to optimize and improve H2 production, it is essenti...

Occurrence of Haemophilus influenzae strains in three Brazilian states since th...

Few vaccines in history have induced such a dramatic decline in incidence over such a short period of time as the Haemophilus influenzae type b (Hib) conjugate. This vaccine was introduced in 1988 in the United States, but only in 1999 was Hib immunization introduced by the Brazilian Ministry of Health as part of the routine infant National Immunization Program. The authors analyzed 229 H. influenzae (Hi) isola...

Sensibilidade e especificidade da core biopsy estereotática no diagnóstico hist...

Recentemente a core biopsy estereotática tem sido proposta como método alternativo na avaliação inicial de lesões mamárias impalpáveis. OBJETIVO: Os autores propõem-se a analisar a acurácia do diagnóstico histopatológico em material de core biopsy estereotática. Discutem a aplicabilidade de testes usados para variáveis nominais como sensibilidade e especificidade na avaliação de gradações de qualidade, tais com...
