This study investigates the acquisition of second language (L2) rhythm by speakers of Dutch and Spanish, two languages that traditionally are considered to be rhythmically different. Specifically, it investigates whether the direction in which the L2 is learned (from Dutch to Spanish, or vice versa) influences the ease of acquisition. Dutch has relatively complex syllable structure and uses ext...

Abstract Aqueous dispersions of gold and silver nanoparticles (NPs) stabilized with sodium citrate, as well polymeric NPs based on poly(lactide- co -glycolide) (70 : 30 mol %) poly(vinyl alcohol) have been obtained. The sizes determined by transmission electron microscopy (TEM), dynamic light scattering (DLS), analytical ultracentrifugation (AUC). It has shown that the diameter both metallic pa...

By a method of differential centrifugation and tryptic digestion suspensions of elementary bodies have been prepared from chorioallantoic membranes of chick embryos infected with vaccine virus. The infective titer of the final suspension of elementary bodies was usually the same as that of the original tissue emulsion. Elementary bodies from infected chick membranes were agglutinated as well by...

BACKGROUND A degenerative left shift (DLS) is reported to be a poor prognostic indicator in dogs and cats. Limited data in dogs and no studies in cats have been published to investigate this claim. HYPOTHESIS/OBJECTIVES To characterize the feline population affected by DLS and to determine if the presence and severity of DLS are associated with increased risk of euthanasia or death. ANIMALS...

This paper describes a novel optical method for label-free quantitative imaging of cerebral blood flow (CBF) and intracellular motility (IM) in the rodent cerebral cortex. This method is based on a technique that integrates dynamic light scattering (DLS) and optical coherence tomography (OCT), named DLS-OCT. The technique measures both the axial and transverse velocities of CBF, whereas convent...

Two recombinant DNA-derived variants of ovine growth hormone were produced, purified, characterized and compared with the authentic pituitary derived GH. The variants oGH3 and oGH5 were isolated by differential centrifugation method and were purified after refolding by ion-exchange chromatography and gel filtration. Both the proteins showed single band on SDS-PAGE and had molecular weight and i...

By MARY C. MoRGAN AND JEAN J. SZAFIP A QUANTITATIVE method for the separation of morphologically intact ftinctional platelets from whole blood is not available at the present time. Methods have been described which use differential centrifugation or sedimentation, with and without washing procedures. The prolonged manipulations required with these procedures to insure total recovery leads to pl...

substantiation of the averaging method for differential equations with maxima is presented. two theorems on substantiates for differential equations with maxima are established.
