4-(diethylamino)salicylaldehyde with 4-nitroaniline is reported‚ with its nickel(II)‚ copper(II)‚ and cobalt(II) complexes. The crystal structures are reported for the four derivatives. While‚ NiII L2 and CuII L2 are centrosymmetric molecules‚ CoII L2 exhibits a pseudo-tetrahedral molecular structure. The quadratic hyperpolarizabilities (b) of HL and CoII L2 ‚ measured by electric field induced second harmonic (EFISH) technique‚ are equal to 66 and 110 Â 10À30 cm5 esuÀ1 ‚ respectively. Beside a geometric effect (pseudo-Td symmetry)

Introduction The topic of our research is about the interference of the first language (L1) to the second language acquisition (SLA). This research looks into the L1 learners’ production of phonemes in their second language (L2)‚ English. The topic is relevant to SLA as speaking is one of the fundamental skills in SLA. Pronunciation‚ in particular‚ is a very important mechanism for a fluent communication. In fact‚ pronunciation is believed to be involved in the learners’ phonological loop. According

In a world that grows smaller every day‚ with instant connection from one side of the globe to the other‚ it becomes more and more important to be able to communicate with ease. This often means that‚ to have an advantage‚ it is necessary to know multiple languages‚ and while some are fortunate enough to be brought up bilingually‚ with parents speaking two languages to the child‚ many need to learn additional languages through education systems. To facilitate this‚ it is imperative to understand

now. There are four skills concerned about language study: writing‚ reading‚ speaking‚ and listening. It means to master English as a language target (L2)‚ students need to master the four skills in English. However‚ student’s first language (L1) is the most challenging factor in improving the skills of L2. Student’s L1 must influence the study of L2 in some areas (Phonology‚ Morphology‚ Syntax‚ and Vocabulary). The writer chose Torajanese as the L1. It is because‚ Torajanese is one of the tribe language
