This paper presents an off-line integrated full ballast to supply a 35 W assembly of Power LEDs. The proposed solution integrates an input PFC stage (a flyback converter operating in DCM) and a DC-DC output converter (a buck converter) into a single switch power stage, operating with peak current control. As it will be shown, this control scheme maintains the current through the load constant, ...

biodegradable polysacharyd-based film was developed by incorporating pimpinella affinis essential oil (pao) into methyle cellulose (mc) at level of 0.5%, 1% and 1.5% v/v. then, its antimicrobial activity tested against 7 bacteria include staphylococcus aureus (ptcc 1431), pseudomonas aeruginosa (ptcc 1151), pseudomonas putida(ptcc 1691),esherichia coli (ptcc 3315), listeria monocytogenes (ptcc ...

– The Myanmar long-tailed macaques (Macaca fascicularis aurea) are distributed to coastal regions in Myanmar, ranging from 10 ̊ to 21 ̊N. Reproductive pattern was studied on a troop of long-tailed macaque inhabiting the steep limestone-rock Bayin Nyi Naung Mountain (16 ̊ 58.2' N), in Southern part of Myanmar, where the climate is seasonal. Bayin Nyi Naung Mountain troop shows the reproductive seas...
