Chemical equilibrium for the reactive system propionic acid + ethanol + ethyl propionate + water at 303.15 and 313.15 K

Chemical equilibrium for the quaternary system propionic acid+ethanol+ethyl propionate +water was experimentally studied at 303.15 and 313.15 K and atmospheric pressure. The chemically equilibrium compositions were determined by gas chromatography and nuclear magnetic resonance analytical methods. It is shown that chemical equilibrium is reached both in homogeneous and heterogeneous area of composition of reactive mixture. The liquid - liquid equilibrium data for the surface of chemical equilibrium were obtained. The thermodynamic constants of chemical equilibrium at 303.15 and 313.15 K were determined

Top09_GMG_1277-Glove.Love

This session contains an extract from a folklore story about a a boy who meets girls in the taiga. With the help of a helper animal, the boy meets several girls and in the end, he chooses the most beautiful one, who is also the richest one

Top09_GNM_1_2-sacred-reindeer

GNM was asked by AL and DM to explain the institution of Sacred Reindeer among the Evens. She explained the details about the consecration of sacred reindeer, and how offerings to sacred fire are made. Then she added how she performs fumigation for children in the village school, about the organisation of the new village festival hebdjek, about Even lullabies and the rituals of femininity (wedding, first menstruation)

Top09_GNM_3_4-fun-misunderst-dial2

The speaker uses a couple of stories from her childhood to illustrate differences between Even dialects. The context is the migration of some 50 Evens from the Allakh-Jun' region (close to the Sea of Okhotsk coast) to her home region, Tompo, in the late 1950s/early 1960. The topic of the anecdotes is the misunderstandings the Tompo Evens had with the newcomers due to dialectal differences

Impact of Layered Perovskite Oxide La_0.85Yb_0.15AlO₃ on Structure and Transport Properties of Polyetherimide

This study aims to improve properties of Ultem® polyetherimide (PEI) by incorporating up to 2 wt% additives of the perovskite oxide La0.85Yb0.15AlO3 (LYA). The structure of dense PEI/LYA films was characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM) in combination with an analysis of their elemental composition using energy-dispersive spectroscopy (EDS). The PEI/LYA films exhibit a two-layer structure. Contact angle measurements revealed hydrophilization of the membrane surface enriched with the perovskite. The transport properties were tested via gas separation and pervaporation processes. The separation selectivity of He/N2 and O2/N2 gas pairs increased with the growth of the LYA content in the membranes. Pervaporation of a methanol(MeOH)–cyclohexane(CH) mixture was effective due to the high sorption of MeOH in the PEI/LYA membranes. The maximal pervaporation separation index was found for the PEI/LYA(2%) membrane
