BACKGROUND AND AIMS Deciduous trees have a seasonal carbon dioxide exchange pattern that is attributed to changes in leaf biochemical properties. However, it is not known if the pattern in leaf biochemical properties - maximum Rubisco carboxylation (V(cmax)) and electron transport (J(max)) - differ between species. This study explored whether a general pattern of changes in V(cmax), J(max), and...
in order to study the effects of soil and foliar application of fe-eddha on some biochemical and physiological traits in safflower under two irrigation regimes an experiment was conducted in 2008 growing season in research field of faculty of agriculture, shahed university. the experimental design was a split-plot based on randomized complete blocks with four replications. mainplots consisted o...
In order to investigate different lines of durum wheat for water stress tolerance, an experiment in the greenhouse was implemented, using 20 lines of durum wheat at two levels of water stress (40% and 70% of the amount of available water was completely drained in 0.4 and 0.7 levels of stress, respectyively and re-irrigation was performed) and a control level (complete irrigation) in the form of...
From January 1999 to May 2001, we investigated seasonal variations in the photosynthetic capacity of Taiwan spruce (Picea morrisonicola Hay.) growing in the subalpine region of subtropical Taiwan (23 degrees 29' N, 120 degrees 53' E, 2600 m a.s.l.). Photosynthetic capacity (near light-saturated net photosynthetic rate, Pnsat, chlorophyll fluorescence (Fv/Fm) and soluble protein concentration of...
Background and Objectives: Febrile convulsion (FC) is the most common seizure disorder in childhood period. Some studies have suggested association between seasons and occurrence of FC. This study was designed to determine demographic features, causes and seasonal variations in cases with FC. Method: In this descriptive, cross sectional study, 282 children 6- 60 months with FC were admitted to ...
background: the mechanisms of virulence and species differences of leishmania parasites are under the influence of gene expression regulations at posttranscriptional stages. in iran, l. major and l. tropica are known as principal agents of cutaneous leishmaniasis, while l. infantum causes visceral leishmaniasis. methods: as a preliminary study, we compared the proteome mapping of the above thre...
The purpose of the present study was to determine whether the daily and seasonal changes in ventilation and breathing pattern previously documented in red-eared sliders resulted solely from daily and seasonal oscillations in metabolism or also from changes in chemoreflex sensitivity. Turtles were exposed to natural environmental conditions over a one year period. In each season, oxygen consumpt...
this study investigated the potential role of age in inductive and deductive grammar learning among iranian foreign language learners. the experimental population consisted of our randomly selected samples including two groups of children (with age of exposure to english within 8-13), and two groups of adults (with age of exposure to english within 11-13). thus, the comparison was between ch...
Background and Aim: Investigation of seasonal suicide might help in learning about the etiology of suicide committers’ behavior. Literature search indicates that a large number of preliminary studies have been carried out on this subject, in many of which seasonal and climatological aspects of suicide have been investigated. In the present study, the seasonal and time pattern of suicide incid...
