Seabird feathers and eggshells are used as bio-monitors for trace metal contamination. Eleven trace element concentrations in wing primaries (n = 21) and eggshells (n = 8) are reported herein for two resident seabirds, Bridled Tern Onychoprion anaethetus and Black-naped Tern Sterna sumatrana, at Pulau Ling and Pulau Tokung Burung, Malaysia. Metal concentration followed the pattern Zn > Cr > Mn > Sr > Cu > Se > Ba > Pb > Cd > Ga > Li. Significant positive correlations existed among all trace metals, except for Cr in Black-naped Tern and Li and Cd in Bridled Tern feathers. We also analyzed metal concentrations in eggshells, and for Bridled Tern, the concentration pattern was Zn > Mn > Se > Sr > Ba > Pb > Co > Cu > Cd, whereas for Black-naped Tern it was Cr > Zn > Mn > Ba > Sr > Se > Cu> Co > Pb. A pairwise positive correlation was significant among most trace metals in feather samples, indicating synergistic effects of two or more elements. More studies are needed to build a baseline database of trace metal concentrations in seabirds of Southeast Asia, as little research on this subject has been conducted in this region.

Real life conversations do not include formal spoken interactions all the time; learning to use slang will help convergence, divergence, and maintenance, which constitute speech accommodation theory. Convergence is “accommodation towards the speech of one’s interlocutors” (Meyerhoff, 2006, p. 307). In other words, how individuals are familiarized to each other’s linguistic features during speech. In the case of ELLs, they needed to gain social approval in their new community, which makes convergence occur. They use slang to maintain their social approval and construct their identity. Their convergence is downward convergence since they use slang to belong to their school community arabic 5 English 41

تناولت الدراسة أبرز جهود علم من أعلام الفقه المالكي الليبيين، وهو الشيخ محمد بن محمد بن عامر رحمه الله، من خلال إلقاء الضوء على جانب من حياته الشخصية، والتعريف بكتابه ملخص الأحكام الشرعية على المعتمد من مذهب المالكية، وطريقة عرضه وأسلوبه فيه.
