Leaf ontogenesis is determinant for the establishment and regulation of its structural functional properties, in addition to being an excellent tool assignment different groups angiosperms. Even though importance leaf morphology anatomy taxonomic use well known, few studies have addressed processes ontogeny Melastomataceae. Herein, we sought define ontogenetic steps Trembleya phlogiformis, high...
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
the rise and stublishment of safavid dynasty was depend on triangle of tasavof, tashayo and royalty, kings legitimized their power upon these. therefore for the understanding the functions of that period we must explore the role of this elements. although application and emphsise upon dignities such as; complete mentor (morshede kamel), deputy of absent imam (nayebe imame ghayeb), and god’s sha...
We n&asured leaf respiration in 18 eastern deciduous forest tree species to determine if there were differences in tempera i m-respiration response functions among species or among c opy positions. Leaf respiration rates were measured in situ an4 on detached branches fordcerpensylvanicum L., A. rubrum i., Betula spp. (B. alleghaniensis Britt. and B. renta L.), Caryq glabra (Mill.) Sweet, Cornus...
this study sought to examine the effect of cooperative game on iranian students achievements in english alphabet learning. cooperative games are games, in which players or teams work together towards a common goal without defeating someone. the methodology used in this study was experimental. the population of the study was 60 female students from the grade one in secondary school in tabriz, ir...
The proceedings present the accepted contributions for the 5 International Workshop on Critical Systems Development Using Modeling Languages (CSDUML’06). CSDUML’06 takes place on October 1, 2006, in Genova, Italy, and is organised in conjunction with MoDELS’06 (October 1 – 6, 2006). The papers represent research in four areas: specification and analysis, system synthesis, verification, and indu...
this study investigated (a) the learners’ existing reading strategy repertoire, (b) the effect of instruction in reading strategies on learners’ strategic performance, and (c) the effect of explicit instruction in top-down reading strategies on reading comprehension ability of intermediate learners. the study was conducted with 40 intermediate efl learners in two groups of experimental and cont...
Peanut (Arachis hypogaea L.) and cotton (Gossypium hirsutum) plants were grown for 4 weeks in saline, isoosmotic rooting substrates with different proportions of K and Na. Isoosmotic media did not affect growth (except at the highest external K concentrations) or estimates of intracellular osmotic pressure in expanding leaves (i.e. osmotic pressure of leaf sap and intracellular osmotic pressure...
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...
We examined whether the spraying of soybean leaves with hydrogen peroxide (H2O2) would alleviate the symptoms of drought stress. Pre-treatment by spraying leaves with H2O2 delayed foliar wilting caused by drought stress compared to leaves sprayed with distilled water (DW). Additionally, the relative water content of drought-stressed leaves pre-treated with H2O2 was higher than that of leaves pr...
