This atlas contains 147 bright-field photomicrographs that illustrate the anatomy of bacteria, algae, fungi, lichens, mosses, liverworts, ferns, conifers, and flowering plants. With each micrograph, there is an interpretive line drawing which is useful since many of the photographs are of fair quality only. The book is representative of thinking in the field of plant anatomy 50 years ago. There...
This paper describes the isolation and characterization of rhamnogalacturonan II, a hitherto unobserved component of the primary ceo wails of dicotyledonous plants. Rhamnogalacturonan II constitutes 3 to 4% of the primary ceo wais of suspension-cultured sycamore (Acerpseudoplatanus) cels. Rhamnogalacturonan II is a very complex polysaccharide yielding, upon hydrolysis, 10 different monosacchari...
in this thesis, structural, electronical, and optical properties of inverse pervskite(ca3pbo) in cubic phase have been investigated.the calculation have been done based on density functional theory and according to generalized gradiant approximate (gga) as correlating potential. in order to calculate the configurations, implementing in the wien2k code have been used from 2013 version. first of ...
in present study we studied using green routes for microwave assisted synthesis of alumina nanoparticles from aluminum nitrate. it was revealed that when plant extracts are used, no specific stabilizer is needed. structural characterization of nanoparticles was studied using x-ray diffraction that showed semi-crystalline structure for two of plant extracts, other xrd patterns had no significant...
Urtica dioica L. is an Iranian native pharmacological plant for which little attention has been paid to the anatomical structure. Medical applications of this plant include diabetes therapy, digestive improvement, anemia and kidney disease therapy. Because climatic conditions can affect the anatomical structure which in turn affects pharmacological compositions, research on the anatomy of this ...
