the benefits of textual input enhancement in the acquisition of linguistic forms have produced mixed results in sla literature. the present study investigates the effects of textual enhancement on adult foreign language intake of two english linguistic forms-subjunctive mood and inversion structures-to explore the role of the type of linguistic items in input enhancement studies. it also invest...

background: inversion of the uterus is very uncommon. patients may present with pelvic pain, vaginal discharge, or hemodynamic shock. case: we report a case of 35 years old women (virgin) who was admitted with profuse vaginal bleeding and cramps of uterus. in the vaginal examination at litothomy position a mass of 58 cm in size was protruded from the vagina. at first myomectomy was performed a...

A method is described by which it is possible to determine the high barrier to ring inversion and hindered rotation by neat racemization of optically active compounds when the racemization is caused by ring inversion or hindered rotation. The method is based preparation of sufficiently pure enantiomers, mainly by chromatography on swollen microcrystalline triacetylcellulose (TAC). By this t...

introduction air pollution as one of the most important technological risks of contemporary era is mainly resulted from the emergence of large cities and fast growing industries. one of the main objectives of climatic and environmental studies is to survey atmospheric pollutions. tabriz is one of the metropolises where air pollution is a problem in it. of course, what is essential regarding the...

 Ab initio calculations were employed to investigate nitrogen inversion as a configuration change that can supply an infinitely useful switchable control mechanism for some <span style="letter-sp...

Abstract. This study introduces a new approach to problem of estimating parameter(s) of a given copula. More precisely, using the concept of the generalized linear models (GLM) accompanied with least square method, we introduce an estimation method, say GLM-method. A simulation study has been conducted to provide a omparison among the inversion of Kendal’s tau, the inversion of Spearman’s rho,...

This paper presents evidence on Mesozoic inversion of basin bounding faults within the Taleqan-Gajereh-Lar Paleograben (TGLP) in Central Alborz Range. For this purpose, well documented stratigraphy data across the TGLP together with the new acquired structural data on the geometry and kinematics of the paleograben basin bounding faults are utilized. The TGLP has evolved through the Early and Mi...
