Seedling regeneration after a high intensity wildfire was assessed in a mixed forest dominated by Eucalyptus species andCallitris endlicheri (Parl.) F.M.Bailey. Patternswere compared against the ‘slow seedling’or ‘tortoise-and-hare’ theory of competitive interactions betweengymnosperms andangiosperms.Browsing effectswere documentedusing fenced plots, and seedling density, mortality and height w...

Eucalyptus is the second most planted tree on earth. Despite this ranking, its mature breeding programs, clonal propagation and deployment and short rotation time make it a leading target for biotechnology improvement. The recently completed eucalyptus genome project provides an enormous opportunity for understanding and developing new traits for eucalyptus forestry. The main obstacle for wides...

Low resistance junctions between axons of crayfish ganglia are studied by freeze-fracture and negative staining . In freeze-fracture, fracture planes that go through a junctional membrane expose two faces, both internal, called face A and face B . Face A belongs to the internal membrane leaflet and faces the gap . Face B belongs to the external membrane leaflet and faces the axoplasm. Face A di...

Eucalyptus plantations are frequently used for the establishment of bee yards. This study was carried on at Fazenda Brejão, northwestern region of the State of Minas Gerais, Brazil. This farm is covered both with native Cerrado vegetation (Brazilian savanna) and eucalyptus plantations. This paper reports on the botanic origin of pollen pellets and honey collected from honeybee (Apis mellifera) ...

We decipher intrinsic three-dimensional shape distributions of molecular clouds, cloud cores, Bok globules, and condensations using recently compiled catalogues of observed axis ratios for these objects mapped in carbon monoxide, ammonia, through optical selection, or in continuum dust emission. We apply statistical techniques to compare assumed intrinsic axis ratio distributions with observed ...

The bone marrow of a patient with light chain myeloma and amyloidosis was substantially infiltrated with basophilic globular particles. The globules, which were confined to the bone marrow, ranged in size from tiny intracytoplasmic inclusions to large (100 mu) extracellular particles. Both the intra- and extracellular globules stained with fluorescent antibody directed against the light chain (...

in this study, the effect of accelerated ripening with encapsulated protease and lipase on physiochemical properties such as fat and moisture, texture and microstructure of brined cheese was investigated. addition of lipase increases hardness by reducing fat globules diameter and increasing casein matrix junction. it also decreases brittleness by fat degradation which is responsible for plastic...

Both free and cracked surfaces of the saccus vasculosus in adult rainbow trout (Salmo gairdneri) have been investigated by scanning electron microscopy (SEM). The saccus vasculosus is the rich-folded epithelium composed of highly specialized coronet cells, supporting cells, and presumable liquor-contact neurons. The coronet cells are characterized by both numerous specialized cilia, so-called "...

Dear Sir, We read the excellent short review article of Higgins et al. (1) on contact allergy to and the safety of eucalyptus oil with great interest. Having recently finished writing a full literature review of contact allergy to and the chemical composition of essential oils (2), we would like to give some additional information on eucalyptus oil. Also, we will address the question raised by ...
