This study employs the Taguchi method to approach the optimum co-gasification operation of torrefied biomass (eucalyptus) and coal in an entrained flow gasifier. The cold gas efficiency is adopted as the performance index of co-gasification. The influences of six parameters, namely, the biomass blending ratio, oxygen-to-fuel mass ratio (O/F ratio), biomass torrefaction temperature, gasification...

A jade-vermelha (Mucuna bennettii F. Muell, Fabaceae) é uma trepadeira exótica facilmente encontrada em vários pontos do Distrito Federal, usada como forma de ornamentação quadras e parques na região. Esse trabalho tem objetivo relatar pela primeira vez a ocorrência da cochonilha Coccus hesperidum L. (Hemiptera: Coccidae) M. bennettii. Amostras cochonilhas foram coletadas duas plantas situadas ...

Lemon oils are amongst the highest volume and most frequently traded of flavor fragrance essential oils. Citronellal citral considered key components responsible for lemon note with (neral + geranial) preferred. Of myriad sources citral, Australian myrtaceous tree, Myrtle, Backhousia citriodora F. Muell. (Myrtaceae), is superior. This review examines history, natural occurrence, cultivation, ta...

Increases in plant size and structural complexity with increasing age have important implications for water flow through trees. Water supply to the crown is influenced by both the cross-sectional area and the permeability of sapwood. It has been hypothesized that hydraulic conductivity within sapwood increases with age. We investigated changes in sapwood permeability (k) and anatomy with tree a...

A method of estimating trunk and branch volumes of single trees is presented that uses a combination of elementary fi eld measurements, terrestrial photography, image rectifi cation and on-screen digitising using commercial software packages and automated volume calculation. The method is applicable to a variety of different sized trees in situations where the trunks are clearly visible. Result...

theeffect of salt stress on the pysiological and biochemical responses of the seedlings of eight eucalyptus species viz. e. kingsmillii, e. tetragona, e. salubris, e. occidentali, e. microtheca, e. camaldulensis, e. globules and e. sargentii was analyzed. four month-old seedlings grown in greenhouse were watered by five levels of salt solution (0, 50, 100, 150 and 200 mm of nacl) in five replic...

Methanolic leaf extracts of Erythroxylum australe F. Muell. produced eight O-conjugated flavonoids. Six of the flavonoid aglycones were dihydroisoflavones (all dihydro-orobol derivatives), one a flavanone, eriodictyol, and one a flavonol, quercetin. The major glycosides of the flavonoids included mono-glucosyl-rhamnosyls and dirhamnosyl-glucosides with either 3, 5, 7 or 3', 4' linkage or a comb...
