The use of high yielding and resistant to drought stress cultivars in crops is one of the proper way to incorporation other water deficit management methods. This study in order to evaluate grain yield and morphological traits, an experiment was conducted with 100 genotypes of durum wheat which were planted based on lattice design with three replications under normal and drought stress conditio...
This experiment was conducted to study the effects of water deficit stress on morphological traits, yield and yield components of 60 maize single cross hybrids at Torough Agricultural and Natural Resources Research C enter located in Mashhad, Iran on 2013. This experiment was laid out in randomized complete block design with three replications. The irrigation treatments were consisted of two ...
This work highlights the role of otolithic morphometrics, shape indices and ultrastructure in the identification of three Mullidae species from the Red Sea. Differences in otolithic measurements were detectable in all three-goatfish species. The statistical analysis of otolithic morphometric parameters showed that otolithic measurements are good indicators of fish size. For all three species, t...
the present study reports an analysis of response articles in four different disciplines in the social sciences, i.e., linguistics, english for specific purposes (esp), accounting, and psychology. the study has three phases: micro analysis, macro analysis, and e-mail interview. the results of the micro analysis indicate that a three-level linguistic pattern is used by the writers in order to cr...
Food intake of rats increases during pregnancy. This requires changes in the structure of the small intestine to absorb additional food. The aim of the present study was to investigate the morphological changes in the layers of small intestine in rats during pregnancy. Duodenum, jejunum and ileum of 18 pregnant Sprague-Dawley rats (day 7, 14 and 21 of pregnancy) were collected. Villous height a...
BACKGROUND Pathological changes of the respiratory muscles (RM) during the development of chronic obstructive pulmonary disease (COPD) have not yet been studied in detail. OBJECTIVES The aim of the research was to assess RM status in COPD and the relationship between echodensitometric and morphological changes in the RM. MATERIAL AND METHODS The participants 152 male COPD patients were divi...
In this study, 59 adult canine sacrums, comprised of 30 male and 29 female, with 23 different morphological types were used. A total 5 osteometric measurements taken from each the sacrums a 3 sacrum index indices calculated using these measurements. SPSS 21.0 program was used for statistical calculations, after calculating mean standard deviation values both female individuals, T-test applied t...
In recent years, Multimetric Indices (MMIs) have received a lot of attention thanks to their ability develop integrative evaluations water quality, particularly in lagoons. this article, we propose new MMI for determining the quality The proposed index is composed biotic and abiotic indicators, particular macroinvertebrates, macrophytes morphological indicators. based on geometric representatio...
The main objective of current study was application of direct gradient analysis, to identify the most important environmental factors affecting the Morphological characteristics in plant medicinal Verbascum songaricum.In this study species were collected from Rangeland, Howz Vally, Gahiz, Semeiroom intrance and Ghadam places in Isfahan province as well as Dena in Kohgiloye and Boyer Ahmad prov...
the zagreb indices are the oldest graph invariants used in mathematical chemistry to predictthe chemical phenomena. in this paper we define the multiple versions of zagreb indicesbased on degrees of vertices in a given graph and then we compute the first and secondextremal graphs for them.
