this study focuses on achieving high stiffness/strength and good fr characteristic of nylon 66/mca/nc nanocomposites, prepared via melt compounding by twin screw extruder. a synergistic effect of flame retardant systems based on melamine cyanurate and zinc borate on the flammability and mechanical behaviours of crysnanoclay reinforced nylon 66 nanocomposites have been reported. mechanical test ...

in thermal cracking plants, it is desired to apply an optimal temperature profile along the reactor to minimize the operation cost. in this article a simulator is developed by the use of a mathematical model, which describes the static operation of a naphtha thermal cracking pilot plant. the model is used to predict the steady state profiles of the gas temperature and product yields. using a dy...

Exceeding the electric field’s limit value is not allowed in vicinity of high-voltage power lines because both legal and safety aspects. The design parameters line must be chosen so that such cases do occur. However, analysis several operating Europe found field strength many exceeds legally prescribed for general public. To illustrate this issue its importance, measurement finite element simul...

Power system usually have standard static ratings (SLR) that determines load constraints. It refers to the maximum allowable conductor ampacity pre-determined by worst-case conditions (high ambient temperature, solar radiation, and low wind speed) of their overhead transmission lines, rises line’s temperature without infringing ground clearance causing loss tensile strength. Line’s dynamic capa...

Forty hearing-impaired participants were fitted with the ReSound ED2 two-channel two-memory wide dynamic range compression hearing aid. After participants had worn the ED2 for six months, the final settings for crossover frequency (CF) and compression ratio (CR) for each channel were documented. There were statistically significant correlations between the slope of hearing loss and (he programm...
