The Hoechst 33258 - Giemsa banding patterns were compared on axolotl (Ambystoma mexicanum Shaw) and axolotl - tiger salamander (Ambystoma tigrinum Green) species hybrid prophase chromosomes. Approximately 369 bands per haploid chromosome set were seen in the axolotl and about 344 bands in the tiger salamander. In the haploid set of 14 chromosomes,(More)
In WCDMA networks, radio network controller (RNC) is a potential bottleneck for TCP connections - due to difference in available bandwidth between the core network (CN) and the radio access network (RAN). This may result in packet data convergence protocol (PDCP) buffer overflows or excessive delays at the RNC, as PDCP buffers are flow-specific. In order to(More)
In this paper, we address the radio dimensioning issue that arises from the introduction of novel services in WCDMA networks. To investigate the impact and entailed limitations of the deployment of new services on the performance of the offered ones, we propose plain methods and a simulator for radio interface dimensioning. The tool (based on throughput(More)
It has been shown that lens regeneration from the iris of the newt Notophthalmus viridescens is dependent on the presence of neural retinal tissue in organ culture and in vivo. The recent discovery of various eye-derived growth factors (EDGFs) in the bovine retina [14] prompted us to investigate whether one of these factors may be involved in the(More)
During eye development in the axolotl (Ambystoma mexicanum Shaw), morphogenetic movements bring together tissues from head epidermis, neuroectoderm and neural crest. The stages 0 to 14 of axolotl eye development were expanded from Rabl's (1898) stages 1 to 10 and correlated with Harrison's (1969) stages. At the onset of neurulation (stage 13 of Harrison),(More)
Lenses of newts (genera Notophthalmus, Triturus, Cynops) regenerate from irises in the presence of retinae of larval frogs (Rana) or adult salamanders (Hynobius, Ambystoma), species which are themselves incapable of lens regeneration from the iris. In newts, bovine pituitary thyrotropin preparation NIH-TSH-B8 can also stimulate lens regeneration from the(More)
