The present work aims at evaluating temperature dependency of product evolution from pyrolysis of binary mixtures of low density polyethylene (LDPE), and polyethylene terephthalate (PET). Product distribution studies have been reported for three different mixture compositions (20:80, 50:50, and 80:20) in the temperature range of 300-600oC, for a wide range of hydrocarbon products (C5-C44) and t...

The question of whether a binary mixture of amino acids is detected by fish as a unique odor or whether the qualities of the individual components are retained within the mixture was investigated in channel (Ictalurus punctatus) and brown bullhead (Ameiurus nebulosus) catfish, species that are highly similar in their olfactory receptor and behavioral responses to amino acid odorants. Catfish re...

Fluorous protic ionic liquids (FPILS) containing a perfluorinated anion and hydrocarbon cation have been observed to segregate into nano-scale fluorocarbon, hydrocarbon and polar domains. The solubility and interactions of ethanol and butanol in a series of FPILs has been investigated by synchrotron source small and wide angle X-ray scattering. Nano-scale objects were found to be present within...

In this paper the steady state performance of a variable conductance heat pipe, which its working fluid consists of two components (R11+ R113) is modeled. The role of the liquid film momentum and axial normal stresses are considered by use of the mean property of mixture and the governing equations are solved by conventional numerical methods. The results of the present model have been compared...

biodegradation of petroleum hydrocarbons (20 g/kg dw soil) was investigated in 3 media, differing in the kind of petroleum fractions. in the laboratory experiments, during 5 months, the activities of petroleum hydrocarbon-degrading microorganisms and dehydrogenase activity of soil was determined. gas chromatographic analysis showed the biological decontaminations for gas oil, kerosene and synth...

Cuticular lipids include a diverse array of hydrophobic molecules that play an important role in the water economy of terrestrial arthropods. Their waterproofing abilities are believed to depend largely on their physical properties, but little is known about interactions between different surface lipids to determine the phase behavior of the total lipid mixture. I examined the biophysical prope...

Intelligibility of ideal binary masked noisy speech was measured on a group of normal hearing individuals across mixture signal to noise ratio (SNR) levels, masker types, and local criteria for forming the binary mask. The binary mask is computed from time-frequency decompositions of target and masker signals using two different schemes: an ideal binary mask computed by thresholding the local S...
