In this research, five species of the genus Polystichum, belonging to Dryopteridaceae, namely, P. lonchitis, P. woronowii, P. setiferum, P. braunii and P. aculeatum, were collected from Gilan and Mazandaran Provinces and studied micro-morphologically. In order to compare the spores, their morphology and their ornamentation was studied. The spores each were picked from sporangia and each sample ...

OBJECTIVE The objective of this study was to evaluate the relationship between the trabecular bone microarchitecture and cortical bone morphology by using micro-computed tomography (micro-CT) and dental cone-beam computed tomography (dental CT). MATERIALS AND METHODS Sixteen femurs and eight fifth lumbar vertebrae were collected from eight male Sprague Dawley rats. Four trabecular bone microa...

calcium carbonate nano-particles were synthesized by a reverse micro-emulsion method at room temperature with tween® 80 and span® 80 as co-surfactants. the nano-particles synthesized were surface modified by stearic acid. an important operating variable in the span 80-tween 80/toluene/water reverse micro-emulsion system, the ω-value (water/surfactant molar ratio) was investigated. the material ...

Two multicriterion decision-making methods, namely ‘compromise programming’ and the ‘technique for order preference by similarity to an ideal solution’ are employed to prioritise 22 micro-catchments (A1 to A22) of Kherthal catchment, Rajasthan, India and comparative analysis is performed using the compound parameter approach. Seven criteria – drainage density, bifurcation ratio, stream frequenc...
