T he H.264/MPEG-4 Advanced Video Coding standard (H.264/AVC) is the newest video coding standard jointly developed by the ITU-T Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG). H.264/AVC has achieved a significant improvement in compression performance compared to prior standards, and it provides a network-friendly representation of the video that addresses...

The use of alternative sources for fuel production has been gaining attention in the past years. Thus, role biodiesel seems to be crucial, as it can contribute sustainable economic growth developing countries. main raw materials are vegetable oils, obtaining fatty acid methyl (or ethyl) esters through transesterification with methanol ethanol). properties these natural feedstocks influence qual...

b a ckground:   eco-faunistic  studies  are  inevitable  step  in  environmental  researches.  aquatic  organisms  like caddisflies are known as biological indicators for water quality assessment and water resource management. they have special role for energy flow in the freshwater habitats as food web and food chain among aquatic creatures. methods: in addition to an extensive literature revi...

In this research, biodiesel was produced using chicken fat in the presence of calcium oxide nano-catalyst. To do so, the effect of various parameters like temperature, reaction time, catalyst amount and methanol to oil ratio was investigated on the biodiesel production. The results showed that the best conditions for biodiesel production were obtained such as the temperature of 65oC, methanol t...

BACKGROUND Timely recognition of acute coronary syndrome remains a challenge as many biomarkers, including troponin, remain negative in the first hours following the onset of chest pain. We assessed the diagnostic accuracy of heart-type fatty acid binding protein (H-FABP), a cardiac biomarker with potential value immediately post symptom onset. METHODS AND RESULTS Prospective monocentre diagn...

ÐThis paper presents a floating-point addition algorithm and adder pipeline design employing a packet forwarding pipeline paradigm. The packet forwarding format and the proposed algorithms constitute a new paradigm for handling data hazards in deeply pipelined floating-point pipelines. The addition and rounding algorithms employ a four stage execution phase pipeline with each stage suitable for...

common carp, cyprinus carpio (l.) were blood-sampled after 0, 2, 6, 12, 24, 48 and 72 h fasting to find serum baseline levels. there was a significant difference in serum glucose, lactate, triglyceride and total protein but not cholesterol, albumin and calcium levels among the treatments. glucose levels increased with fasting tine and reached to a peak after 6 h. then, the glucose level decreas...
