Actiniopteris radiata (Swartz) Link. is a fern belonging to the family Pteridaceae. The spores collected from the pinnae of A.radiata was inoculated in Knudson’s C and Knop’s medium at pH 5.8. The ontogenic pattern such as germination type, prothallial development and micromorphological changes were studied in detail. The germination of the spore was Anemia type. The gametophyte development was...

This is the case, in particular, because a very high variability was observed both in the thin sections and in the field and the information provided by micromorphology was only of local significance, restricted to the area of thin sections. Comparison of thin sections with the field data shows that micromorphology has no potential for extrapolation of results to the level of context or phase, ...

Soil micromorphology was applied to specify flow domains in different soils and to select a suitable numerical model for simulation of water flow and herbicide transport. Pore structure detected on soil micromorphological images represented in all cases domains of prevailing water flow and solute transport. Depending on pore configuration and boundary conditions either water immobilization or p...

In order to evaluate the influence of masticatory movement on cranial bone mineral density (BMD) and osteocyte and osteoblast micromorphology, we conducted a study in rats fed with solid feed (n=10) and powdered feed (n=10). Cranial BMD was measured by dual X-ray absorptiometry (DXA). Osteocyte morphology was evaluated by light microscopy. In addition, some of the tissue was treated with EDTA-K...

BACKGROUND To quantify the development of radiation neuropathy in corneal subbasal nerve plexus (SNP) after plaque brachytherapy, and the subsequent regeneration of SNP micromorphology and corneal sensation. METHODS Nine eyes of 9 melanoma patients (ciliary body: 3, iris: 2, conjunctiva: 4) underwent brachytherapy (ruthenium-106 plaque, dose to tumour base: 523 ± 231 Gy). SNP micromorphology ...

Fine details of the internal and external morphology of Cryptococcus neoformans as seen in ultrathin sections are described and illustrated with electron micrographs. The capsule characteristic of this species contained microfibrils (30 to 40 A in diameter) that appeared to radiate from the cell wall and to coil and intertwine in various directions. These thin, uniformly structured, electron-de...

OBJECTIVE The purpose of this study was to assess the effect of home-use bleaching agents containing 10% carbamide peroxide and 7.5% hydrogen peroxide on enamel microhardness and surface micromorphology. MATERIAL AND METHODS Enamel slabs (n=10) received the bleaching agents for 1 h/day and remained in artificial saliva solution for 23 h/day, during a total period of 21 days. Control group was...

This paper presents data from the first part of a major project designed to investigate the micromorphology of cultivated soils. In particular, the initial phase of the project is concerned with an investigation into methods for the identification and quantification of cultivation features in soil thin sections using image analysis techniques. In 1993 a range of soil samples of known cultivatio...
