A new principle of quantitative and qualitative analysis of binary organic mixtures is offered, which is based on an ability of calixarene receptor for specific polymorphic transitions related to the composition of the analyzed guest mixture. The ability of tert-butylcalix[6]arene to remember selectively some guests bound from headspace both of pure liquids and their binary mixtures is used. Th...

This paper describes the development of a system to transcribe and summarize voicemail messages. The results of the research presented in this paper are two-fold. First, a hybrid connectionist approach to the Voicemail transcription task shows that competitive performance can be achieved using a context-independent system with fewer parameters than those based on mixtures of Gaussian likelihood...

abstract: â in this study, the change in the crystalline structure of gas hydrate was predicted for ternary mixture of methane-ethane-water. for this purpose, the tangent plane distance (tpd) minimization method was used. first, the calculations were performed for the binary mixtures of methane-water and ethane-water as the gas and liquid phases. the results show that for a binary mixture of th...

Mechanical alloying of binary and ternary elemental powder mixtures with the nominal compositions of Mg2Ni and Mg(2-x)MnxNi (x= 0, 0.05, 0.10 and 0.15 at. %) were carried out in a planetary ball mill for various milling times of 5, 10, 15, 20, 30 and 60 h. X-ray diffraction and field emission scanning and transmission electron microscopy were used for the characterization of the milled products...

The lack of variation in antifungal drugs, and the misuse or inappropriate use usually causes resistant strains of the yeast in human’s normal flora. Unfortunately, a large number of Candida infection cases in immunosuppressed patients with insufficient treatment eventually can cause patient's death. The aim of this study was to evaluate the in vitro conventional antifungal azole compounds with...

We investigated the neural processing of binary gustatory mixtures of amino acids by the facial taste system of the channel catfish, Ictalurus punctatus. In vivo electrophysiological recordings indicated that the magnitude of both integrated and single-unit facial taste responses to binary mixtures of amino acids was greatest if the components bound to independent receptor sites. Facial taste r...

some drugs have low bioavailability due to their poor aqueous solubility and/or slowdissolution rate in biological fluids. stiripentol (stp) is a novel anticonvulsant drug that isstructurally unrelated to the currently available antiepileptics. it has poor aqueous solubilityand its solubility has to be enhanced accordingly. polyethyleneglycol 6000 (peg-6000) iscommonly utilized as a hydrophilic...
