Any σ ∈ Gal(L1L2/K) restricted to L1 or L2 is an automorphism since L1 and L2 are both Galois over K. So we get a function R : Gal(L1L2/K)→ Gal(L1/K)×Gal(L2/K) by R(σ) = (σ|L1 , σ|L2). We will show R is an injective homomorphism. To show R is a homomorphism, it suffices to check the separate restriction maps σ 7→ σ|L1 and σ 7→ σ|L2 are each homomorphisms from Gal(L1L2/K) to Gal(L1/K) and Gal(L2...

This study aims at investigating whether Persian native speakers highly advanced in English as a second language (L2ers) can switch to optimal processing strategies in the languages they know and whether working memory capacity (WMC) plays a role in this respect. To this end, using a self-paced reading task, we examined the processing strategies 62 Persian speaking proficient L2ers used to read...

The use of L1 in language classroom has been traditionally repressed by applied linguists. However, in recent years, it is believed that switching to L1 can be considered a pedagogical instrument by teachers rather than a heterodox. Consequently, this two-phase study was an attempt to investigate the functions that are fulfilled by EFL teachers through their use of L1. In the first phase (i.e.,...

Recently, it has been shown that a number of hydroxypyridinones such as 1,2-dimethyl-3-hydroxypyridin-4-one (L1) are useful for the treatment of iron overload in place of desferrioxamine in thalassaemic patients. In this study, the intestinal absorption (I.A.) of L1 and one of its analogues namely 2-methy-3-hydroxypyridin-4-one (L2), which possesses a higher partition coefficient (Kpart) than L...

Abstract The role of EFL lecturers’ first language (L1) in the EFL courses has been an ongoing debate. A monolingual approach to EFL suggests that the use of the target language solely in foreign language (FL) classroom improves learning of the target language. Accordingly, the purpose of the present study was to investigate the attitude of Iranian lecturers and EFL learners towards using L1 as...

To date, little research on pragmatic transfer has considered a multilingual situation where there is an interaction among three different languages spoken by one person. Of interest was whether pragmatic transfer of refusals among three languages spoken by the same person occurs from L1 and L2 to L3, L1 to L2 and then to L3 or from L1 and L1 (if there are more than one L1) to L2. This study ai...

L1-CAM (L1 cell-adhesion molecule), or more simply L1, plays an important role in the progression of human carcinoma. Overexpression promotes tumour-cell invasion and motility, growth in nude mice and tumour metastasis. It is feasible that L1-dependent signalling contributes to these effects. However, little is known about its mechanism in tumour cells. We reported previously that L1 is cleaved...
