CONTEXT: Liposomal encapsulation of drugs can potentially ameliorate toxicities and improve acute and chronic tolerance. The increased uptake of liposomes by colon adenocarcinoma cell lines may enable DaunoXome to circumvent the p-glycoprotein-mediated anthracycline resistance of colon cancer cells. PURPOSE: To determ…
Abstract In a previous study, we have investigated the structure, crystallization, and morphology of poly(aryl ether ketone ketone), PEKK, copolymers prepared from diphenyl ether (DPE), terephthalic acid (T), and isophthalic acid (I) with T/I ratios from 100/0 to 50/50. These materials were considered as having ‐DPE‐…
Abstract The roughness of the silver electrode was changed by variation of parameters of the oxidation–reduction procedure. The roughness size has been estimated qualitatively from the angle distribution of elastically scattered light. Quantitatively measurement of roughness by scanning electron microscopy and transmi…

A study of thread tensions on a lockstitch sewing machine was made, measuring simultaneously both the needle and bobbin thread tensions. Investigates the relationship between the peak tensions generated during the experiments and the corresponding seam balance. It was found that under the conditions of the experiments…
Article Kinetic Studies of Unirradiated UO2 Dissolution under Oxidizing Conditions in Batch and Flow Experiments was published on December 1, 1994 in the journal Radiochimica Acta (volume 66-67, issue s1).

A structural transition in the nematic liquid crystal 4'-pentyl-4-cyanobiphenyl (5CB-\ensuremath{\beta}${\mathrm{d}}_{2}$) doped with chiral agents CB15 and CE2, confined to submicrometer cylindrical cavities of alumina membranes, is detected by deuterium nuclear magnetic resonance ${(}^{2}$H NMR). These cavities have…
Measurements of the complete set of thermogalvanomagnetic coefficients of Sn-doped Bi95Sb5 have been carried out from liquid nitrogen up to room temperature as a function of magnetic field strength and crystallographic direction (parallel and perpendicular to the trigonal axes). The dependences of the transport coeffi…

Phase separation of a binary Lennard-Jones fluid confined in a cylindrical pore is studied by molecular dynamics simulations. The wetting interaction of the fluid molecules with the walls of the single pore is derived from the Lennard-Jones potential. Existence of long-lived metastable states is found even in the pres…

The microstructure and mechanical properties of magnesium-gadolinium and magnesium-gadolinium-yttrium alloys have been studied. There are extended magnesium solid solution areas in the systems narrowing as temperature lowers. The decomposition of the magnesium supersaturated solid solutions results in significant stre…
When a sufficient density of permanent random crosslinks is incorporated into a system of macromolecules, the system undergoes a continuous equilibrium phase transition from a liquid to an amorphous solid state. In this solid state, a certain fraction of monomers are entirely delocalised. The remaining fraction ( i.e.…

Abstract Direct evidence for the locations of the hydrogen atoms in the dihydrogenhexaniobate anion has been obtained by a single-crystal X-ray diffraction method. Hexasodium dihydrogenhexaniobate icosahydrate (1), Na6[H2Nb6O19]·20H2O, crystallizes in triclinic form, space group , a = 10.364(2), b = 12.205(2), c = 9.0…
This paper reports an extensive study of the static (spontaneous polarization, ${\mathit{P}}_{\mathit{s}}$, tilt angle \ensuremath{\theta}, and pitch) and dynamic properties of a ferroelectric liquid-crystalline polymer. It is shown that a ferroelectric liquid-crystalline polymer (diluted polysiloxane) exhibits physic…
In conventional energy conversion processes, the fuel combustion is usually highly irreversible, and is thus responsible for the low overall efficiency of the power generation process. The energy conversion efficiency can be improved if immediate contact of air and fuel is prevented. One means to prevent this immediat…
Nickel hydroxide thin films were prepared onto transparent conductive tin oxide (NESA) substrates by potentiostatic electrolyses of a nickel ammine complex solution at various potentials (0.6 to 1.5 V vs. Ag / AgCl ). Nickel hydroxide thin film (F0.7) obtained at relatively lower anodic potential (0.7 V) showed enhanc…
