Large multilamellar non-ionic surfactant vesicles (niosomes) with diameters of around 800-900 nm prepared from a C16 triglyceryl ether with and without cholesterol and containing doxorubicin (Adriamycin) were administered to S180 tumour-bearing NMRI mice by bolus injection. Although in-vitro drug release from choleste…
Four ferrimagnetic chains formed by manganese hexafluoroacetylacetonate and different nitronyl nitroxide radicals 2-R- 4,4,5,5-tetramethy1-4,5-dihydro1-H -imidazolyl-1 - oxy 3-oxide (with R = isopropyl, ethyl, methyl, and phenyl) were synthesized. The magnetic susceptibility measurements in the range 6300 K show a div…
Abstract An automated tension infiltrometer useful for a range of water tensions from 0.02 to 0.50 m and for infiltration rates of 1 × 10 −8 to 5 × 10 −4 m s 1 is described. Infiltration rates are calculated from the change in water height in a Mariotte column. Water height is automatically measured by using the diffe…
The scattering matrix, differential cross section, and total cross section for supramicrometer-size nematic droplets in a polymeric matrix are derived in the anomalous-diffraction approach. Scattering patterns are calculated in detail for three different nematic-director configurations: one characteristic of a droplet…

Dense ‘‘diamondlike’’ hydrocarbon films (a-C:H) are a class of amorphous solids which can be condensed as thin films from nonequilibrium environments by several plasma deposition techniques. Films with hydrogen atom fractions from 0.5 to 0.6 select a structure with an average coordination number close to the theoretic…

A single-crystal Lorentz correction is derived for the case of a general scan through an out-of-plane reflection on a four-circle diffractometer with relaxed sample-to-detector collimation. When the Lorentz correction is expressed in terms of the incremental steps in the Eulerian setting angles, structure amplitudes o…
α-titanium single crystals, containing three different amounts of interstitial impurities, have been tested in compression at temperatures between 77 and 700 K. The mechanical behaviour is characterized by a strong temperature dependence of the yield stress for slip on the primary prismatic slip plane (1010)[1210], a…
In the directional solidification of concentrated alloys, the frozen solid region is separated from the melt region by a mushy zone consisting of dendrites immersed in the melt. Simultaneous occurrence of temperature and solute gradients through the melt and mushy zones may be conducive to the occurrence of salt-finge…
An explicit form of the spin-adapted multireference coupled-cluster formalism in the linear approximation is developed for the special case of a two-dimensional model space involving only closed-shell-type configurations. The formalism is applicable to a number of quasidegenerate systems with two valence orbitals of d…

Summary The fundamental, pore-level mechanisms of foam generation are investigated in monodisperse bead packs. First, direct visual observations identify the following generation mechanisms: lamella leave-behind, gas-bubble snap-off, and lamella division. Then, to ascertain the relative importance of these mechanisms,…

A new switching process was observed in surface stabilized ferroelectric liquid crystals. The switching is associated with a third stable state in addition to the well-known bistable states. The appearance of the third state is characteristic of materials with a large spontaneous polarization and is caused by minimizi…
