Abstract The phospholipids (PL) occurring in both ewe and cow milk fat globule membrane were identified quantitatively determined using 31 P NMR spectroscopy with inverse gated decoupled sequences, which allowed a rigorous quantitative analysis. A strict relation between amount distribution of PL type feeding was found. method calibrated over mixture standards. recently introduced solvent constituted by monophasic dimethylformamide/triethylamine/guanidinium hydrochloride used. Compared to...

Biocompatible systems formulated for use in the food, cosmetic, and pharmaceutical fields are characterized. Ternary phase diagrams of mixtures natural lipids (glycerol trioleate, glycerol monooleate, diglycerol lecithin) water were investigated by means optical microscopy polarized light multinuclear NMR spectroscopy. All showed a microemulsion region at high oil content large area coexistence two liquid crystalline (hexagonal lamellar) phases. 1H 13C self-diffusion measurements used to...

Self-assembled structures formed by perfluoropolyether (PFPE) carboxylates with hydrophobic chain terminated Cl−C3F6O, and either sodium or ammonium counterions, have been explored in aqueous binary systems. The focus is on the different counterion-specific micelles liquid crystals formed. These detected characterized via optical microscopy, SAXS, NMR. All Cl−PFPE surfactants form lamellar cubic independently of length counterion. Nonspherical for shortest PFPE anomalous swelling phases...

14N NMR relaxation rates were measured in ternary DDAB water-in-oil microemulsions to investigate structural transitions along oil dilution lines. A two-step model of was used estimate the slow correlation times surfactant interface. The interpretation terms percolation theory gave critical exponents agreement with static and dynamic regimes, depending either on volume fraction dispersed phase or type.

Oil-in-water fluorinated microemulsion aggregates were diluted at high water content, thus taking the system outside regime of thermodynamic stability. The kinetic stability was studied by an analysis 19F NMR chemical shifts. microemulsions formed from mixtures three homologous perfluoropolyether (PFPE) sodium carboxylates purity. They had a Cl-terminated perfluoroalkyl group and differed in number perfluoro-isopropoxy units chain. Two PFPE oils having different chain lengths...

Supercritical carbon dioxide (SC-CO 2 ) was used for anhydrous ovine milk fat (AMF) fractionation. Two different fractions were obtained: a low molecular weight triacylglycerol (TAG), named fraction E, and high TAG, termed R. Fractionation performed at pressure temperature values. The effect of these parameters on the chemical composition two analysed in relation to original AMF. Among searched conditions, 250 bar 40°C gave best fractionation results.

Purpose. The paper aims to understand if digital healthcare can improve young and chronic patient engagement. interpretation follows the doctor-patient relationship, investigating whether telemedicine fosters patients' engagement and, they are young, also of their caregivers. Methodology. study analyses two Italian cases. A questionnaire semi-structured interviews administered detect information on new service's satisfaction, utility, usability. Context. shows that e-health answer widespread...

Abstract A preliminary characterization of the didodecyldimethyl ammonium bromide (DDAB)/water (W)/per fluorooctane (PFO) ternary system at 25°C is presented. The gradual addition water, followed by mixing, to DDAB/PFO mixtures produces very stable emulsions for water contents greater than 20 wt%. On basis macroscopic observation, least four different types form up a content around 97 high conductivity values, water‐continuous domain suggested all compositions. second phase diagram,...

Nell’arte asturiana si possono determinare tre dierenti epoche. Il secondo periodo, il piu originale, de!nisce “ramirense”, perche le sue opere maestre furono erette per conto di Ramiro I. Quando egli fu incoronato, regno asturiano era giunto a una maturita che gli permise grandi imprese artistiche. nuovo stile architettonico e rappresentato da due edi!ci ancora oggi conservati: palazzo Santa Maria de Naranco la chiesa palatina San Miguel Lino, entrambe situate pochi chilometri Oviedo, sul...
