we have two part in this thesis, at first: the interaction of native calf thymus dna (ct-dna) with two anthraquinones including quinizarin (1,4- dihydroxy anthraquinone) and danthron (1,8- dihydroxy anthraquinone) in a mixture of 0.04 m brittone-robinson buffer and 50% of ethanol were studied at physiological ph by uv-vis absorption, florescence, circular dichroism spectroscopic methods, viscos...
the aim of this study was to assess the meat quality attributes of broiler chickens fed diets supplemented with silver nanoparticles coated on zeolite. a total of 375 one-day-old broilers was assigned in a completely randomized design to 1 of 5 treatment groups including: basal diet, basal diet supplemented with 1% zeolite, and basal diet supplemented with one of the three levels of zeolite coa...
AIM To develop mucoadhesive liposomes by anchoring the polymer chitosan-thioglycolic acid (chitosan-TGA) to the liposomal surface to target intestinal mucosal membranes. METHODS Liposomes consisting of phosphatidylcholine (POPC) and a maleimide-functionalized lipid were incubated with chitosan-TGA, leading to the formation of a thioether bond between free SH-groups of the polymer and maleimid...
Iron oxide nanoparticles were synthesized and coated with silica by conventional coprecipitation method. Silica coated iron oxide nanoparticles were surface functionalized with chitosan. Silica coating and chitosan functionalization were confirmed by FTIR and TG-DTA analysis. XRD pattern revealed that the pure phase of Fe3O4 was retained even after coating. Particles of average size 12 nm were ...
in solvo-hydrothermal method, xrd pattern was indicated presence of intermediate of ammonium octatmolybdate and ammonium tetramolybdate, which were changed to stble phase of ?-moo3 annealing. sem images were indicated nanoparticle with semispheical morphology and tem image was demonstrated nanoparticles with a diameter size of 25nm. also in impregnate method. the xrd pattern was shown high crys...
We report the electrochemical characterization of chitosan films deposited at gold electrodes from an acidic solution at reducing potentials. Cyclic voltammetry was used to characterize the deposition and electroactivity of chitosan coated gold electrodes. Chitosan films were found to deposit at gold electrodes at potentials more negative than −1.0 V versus Ag/AgCl, a potential associated with ...
saluk mount is selected for devonian biostratigraphy. this area located at southwest of bojnurd. in this study three sections are selected and two sections, chahar-borj and tabar sections with a thickness of 650 m, which consist mainly of calcareous sediments was studied in detailed but third section, qelli section, with a thickness of about 450m which consist mainly of sandstone and evaporates...
Seasonal changes in °Brix and °Brix/% acid ratio of Florida early season oranges and California 'Washington Navel' oranges were fitted by linear models. The constant term varied with different climatic conditions. The rate of Florida Agricultural Experiment Station Journal Series No. N-00240. Froc. Fla. State Hort. Soc. 103: 1990. change was 0.0256 °Brix/day and 0.0735 ratio/day for Florida ear...
abstract: the present study was undertaken to investigate whether 1) there is any significant correlation between iranian efl/eap learners’ l2 writing proficiency and their willingness to communicate, 2) there is any significant difference between efl and eap learners in terms of willingness to communicate, 3) there is any significant difference in wtc of iranian efl/eap learners with 1- nati...
Background: Edible coating is an effective and widely used approach for preservation of quality fruits. The physiological changes remain intact with edible that leads to maintain the nutritional quality. current study endeavor develop appropriate material may be applied over fruits as freshness indicators. Methods: Chitosan nanoemulsion was prepared ultrasonication guava samples were dipped in ...
