For most acoustic metamaterials, once they have been fabricated, their operating frequencies and functions cannot be adjusted, which is an intrinsic barrier for the development of realistic applications. The study to overcome this limit has become a significant issue in metamaterial engineering. Although with advance metamaterials past two decades, series methods such as electric or magnetic co...

Current paper presents the results of a two-year project during which a consortium of the University of Szeged and the MorphoLogic Ltd. Budapest developed a morpho-syntactically parsed and annotated (disambiguated) corpus for Hungarian. For morpho-syntactic encoding, the Hungarian version of MSD (MorphoSyntactic Description) has been used. The corpus contains texts of five different topic areas...

BACKGROUND Mouse oocytes can be used in conjunction with intracytoplasmic sperm injection (ICSI) as a technique to permit chromosomal analysis of human sperm. However, chromosomes derived both from the human sperm and the mouse oocyte appear simultaneously following ICSI. The present study focused on evaluating whether or not previously enucleated mouse oocytes are usable for the analysis of hu...

Previous research has shown that unilaterally enucleated observers demonstrate better luminance-defined form perception compared to monocularly viewing controls, and similar performance to control observers viewing binocularly (Vision Res. 37(17) (1997) 2465). In Experiment 1 we asked whether the perception of form, where form is defined by other attributes than luminance, is also improved comp...

The use of isolated rabbit eyes for the assessment of eye irritation potential is a recognized alternative to the Draize eye irritation test, because it closely models the in vivo test system, but does not require the exposure to take place in the eyes of living animals. The procedure permits evaluation of undiluted test materials, i.e. as they could enter the in vivo eye test, and in this resp...

The present study examined the influence of post-cleavage time of nuclear donors on the development of reconstituted embryos in bovine nuclear transfer. Blastomeres of 16-cell stage embryos derived from in vitro-maturation, fertilization and culture were used as nuclear donor source. They were treated with 10 microM nocodazole for 12 hr. Blastomeres that cleaved within 3 hr after the removal of...
