Gastroretentive raft liquid delivery system as a new approach to release extension for carrier-mediated drug

open access: yesDrug Delivery, 2018
Gabapentin (GBP), an antiepileptic and anti-neuropathic agent, suffers from short half-life (5–7 h), has narrow absorption window, and is absorbed via carrier-mediated mechanism resulting in frequent dosing, poor compliance, and poor bioavailability (

Macroscopicity of quantum superpositions on a one-parameter unitary path in Hilbert space [PDF]

open access: yes, 2014
We analyze quantum states formed as superpositions of an initial pure product state and its image under local unitary evolution, using two measurement-based measures of superposition size: one based on the optimal quantum binary distinguishability of the

Formation and loss of light absorbance by phenolic aqueous SOA by OH and an organic triplet excited state [PDF]

open access: yesAtmospheric Chemistry and Physics
Brown carbon (BrC) is an important component of biomass-burning (BB) emissions that impacts Earth's radiation budget. BB directly emits primary BrC as well as gaseous phenolic compounds (ArOH), which react in the gas and aqueous phases with oxidants ...

Power Graphs of Finite Groups Determined by Hosoya Properties

open access: yesEntropy, 2022
Suppose G is a finite group. The power graph represented by P(G) of G is a graph, whose node set is G, and two different elements are adjacent if and only if one is an integral power of the other. The Hosoya polynomial contains much information regarding

Hyperfine interaction and magnetoresistance in organic semiconductors [PDF]

open access: yes, 2006
We explore the possibility that hyperfine interaction causes the recently discovered organic magnetoresistance (OMAR) effect. We deduce a simple fitting formula from the hyperfine Hamiltonian that relates the saturation field of the OMAR traces to the ...

Natural nanomaterials : reappraising the elusive structure of the nano-sized mineral ferrihydrite through X-Ray absorption spectroscopy at the iron K-edge [PDF]

open access: yes, 2013
Ferrihydrite is natural ferric oxyhydroxide occurring exclusively nanocrystalline. With ideal formula 5 Fe2 O3 . 9 H2 O, ferrihydrite is quite abundant in sediments, weathering crusts and mine wastes, being characteristic of red pre-soils formed by ...

Direct contribution of ammonia to α-pinene secondary organic aerosol formation [PDF]

open access: yesAtmospheric Chemistry and Physics, 2020
Ammonia (NH3), a gaseous compound ubiquitously present in the atmosphere, is involved in the formation of secondary organic aerosol (SOA), but the exact mechanism is still not well known.

Production of particulate brown carbon during atmospheric aging of residential wood-burning emissions [PDF]

open access: yesAtmospheric Chemistry and Physics, 2018
We investigate the optical properties of light-absorbing organic carbon (brown carbon) from domestic wood combustion as a function of simulated atmospheric aging.

A Logic for True Concurrency [PDF]

open access: yes, 2014
We propose a logic for true concurrency whose formulae predicate about events in computations and their causal dependencies. The induced logical equivalence is hereditary history preserving bisimilarity, and fragments of the logic can be identified which

Fermentation of the milk base with the natural formation of breast milk oligosaccharides — new opportunities in the adaptation of infant formula

open access: yesЛечащий Врач, 2023
Background. Breast milk is the best nutrition for a baby. If breastfeeding is not possible, the choice of infant formula is of paramount importance. It is important that the composition of the formula reflects the composition and effects of breast milk ...
