this study was conducted to investigate the effects of applying methods andamount of ammonium polyphosphate (0, 2 and 4 wt%) on fire retardancy andmechanical properties of wood flour/polypropylene composites. the resultsshowed that addition of fire retardant improved the mechanical properties such astensile and flexural strengths and fire retardancy of composites. but by increasingof fire retar...

We relate the ultrastructure of the giant bipolar synapse in goldfish retina to the jump in capacitance that accompanies depolarization-evoked exocytosis. Mean vesicle diameter is 29 +/- 4 nm, giving 26.4 aF/vesicle, so the maximum evoked capacitance (150 fF within 200 ms) represents fusion of about 5700 vesicles. Two terminals contained, respectively, 45 and 65 ribbon-type synaptic outputs, an...

A series of model scale experiments were conducted to study the fire development in a ro-ro deck with various opening geometries. The performed 1/8 reduced heptane pool as source. Experimental results show that both ventilation factor and position affect development. critical ratio for self-extinguish is 4%, locating at bottom side walls while no self-extinction found other tests. higher larger...

One of the key issues that has emerged in performing a probabilistic risk assessment (PRA) for the spent fuel pool during the decommissioning phase of a nuclear power plant's lifecycle is how much credit can be given to the operating staff to respond to an incident that impacts the spent fuel pool that would, if not attended to, lead to a loss of cooling of the spent fuel and eventually to a zi...

With the rapid development of wireless communication technology, the wireless spectrum resources are dwindling. Cognitive radio (CR) is the key technology to solve this problem. In view of the echo state network advantages compared to traditional recursive neural network, we construct the new neural network, echo state network based on leaky integrate and fire neurons (LIF_ESN), and prove that ...

Abstract The fire behaviour of electric vehicles (EVs) differs from that with combustion engines. Especially the rechargeable energy storage system (REESS) requires special protection measures. materials for REESS housings plays an important role in resistance such systems. Full-scale tests like gasoline pool on complete according to UNECE-R100-8E standard are mandatory EVs. However, these not ...

Subsea gas release is an industrial hazard that can impose fire hazards on offshore facilities near the surfacing area. However, risk assessment of caused by subsea challenged due to inadequate recognition knowledge mechanism and resulting hazards. At present, minimal researches involving from a were reported, this paper extension previous works behavior. This focuses modeling release. A numeri...
