nowadays enhancing critical thinking in learners is considered one of the foreign language teachers’ tasks due to its high position in foreign language classrooms. when it comes to selecting materials for language classrooms, there are obviously some criteria that teachers should apply. the present study aimed at a critical thinking based analysis of ten picture story books and ten folktales th...
Rare earth and trace element concentrations of mineral assemblages including amphibole, plagioclase, epidote group minerals (zoisite and clinozoisite) and relict clinopyroxenes from parental rock of epidote amphibolite from north of Urumia were obtained in situ by LA-ICP-MS analysis. The obtained data were used to study distribution of trace elements among metamorphic phases and relict clinopyr...
in this article, we have focused one some basic and productive information about the properties of spectrum and singular values related to compact operators which are ideals in a c*-algebra of bounded operators. considering a two-sided connection between the family of symmetric gauge functions on sequence of singular values of compact operators and symmetric norms on finite dimensional ope...
the neogene intrusion masses in the noudeh-enghelab area located to the north of sabzevar ophiolite have cut the late cretaceous ophiolitic rocks, sedimentary- volcanic and eocene volcanic rocks and have been covered by pliocene and quaternary deposits. the margin is of lava with basalt, phyric andesite-basalt and andesite and the central parts (dome shaped) composed of phyric andesite-trachyan...
a combined electrodeposition-etaas technique has been applied to the analysis of pb, cd, co, ni, cr and mn in biological samples in order to overcome interferences and to minimize sample pretreatment. it requires minimal sample preparation with the electrolysis process aiding partial decomposition of the organic matrix, adequate for the release and deposition of trace elements. in an initial el...
Any deficiency in trace element content of commercial poultry diets will decrease their performance. To prevent this situation it is necessary to supplement trace minerals in poultry diets to allow the modern birds to reach their genetic potential. The NRC publication as the most famous reference for livestock and poultry nutrients requirement has no recommendation for some less needed trace mi...
background : breast cancer is the most common invasive cancer in females worldwide. it accounts for 16% of all female cancers and 22.9% of invasive cancers in women. 18.2% of all cancer deaths worldwide including both males and females are from breast cancer. in this study we compared few serum elements in patients with benign and malignant breast tumor to find any related prognostic and predic...
Trace elements of quartz document the physical-chemical evolutions growth, which has been a great and most applied tool in study geological settings quartz-forming environments. A classic method is using graphic diagram plots visualizing trace element discriminations trends, examples including Al-Ti (Rusk, 2012, https://doi.org/10.1007/978-3-642-22161-3_14) Ti-Al-Ge (Schrön et al., 1988, https:...
abstract venlafaxine, 1–[2–(dimethylamino)–1–(4–methoxyphenyl) ethyl]cyclohexanol hydrochloride is a novel non-tricyclic antidepressant. venlafaxine is a second generation antidepressant drug, has a neuropharmacologic profile distinct from that of existing antidepressants including tricyclic compounds, selective serotonin reuptake inhibitors and monoamine oxidase inhibitors. venlafaxine impart...
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
