Introducción: el síndrome de bandas amnióticas abarca una variedad anomalías congénitas que incluyen la deformación, disrupción y malformación múltiples órganos. Este tiene diferentes manifestaciones clínicas al nacimiento, como anillos formados por constricción las bandas, amputaciones extremidades malformaciones craneofaciales. La incidencia es aproximadamente 1 en 1,200- 15,000 nacidos vivos...

Neuronal growth cones, the sensory-motile structures at the tips of developing axons, navigate to their targets over distances that can be many times greater than their diameter. They may accomplish this impressive task by following spatial gradients of axon guidance molecules in their environment (Bonhoeffer & Gierer, 1984; Tessier-Lavigne & Placzek, 1991; Baier & Bonhoeffer, 1994). We calcula...

The hypothesis that it is the variability of a person's identity--as opposed to the particular combinations of identities--that produces stress during the acculturation process was examined. Two hundred ninety-five native Anglophone students at the University of Ottawa, Ontario, Canada, provided demographic data and completed the following measures: the Beck Depression Inventory (Beck & Beck, 1...

The Hexapodidae was known to date from the Cenozoic of Veneto by Stevea cesarii Beschin, Busulini, De Angeli & Tessier, 1994, from the middle Eocene of Chiampo Valley (Vicenza), and Palaeopinnixa sp. from the upper Eocene of Possagno (Treviso). Recent discoveries from the Eocene of Vicenza area allowed to describe three new genera and four new species of hexapodids. Bellhexapus granulatus n. ge...

This project was an experiment on the feasibility of superconductorbased maglev trains. Two classmates, Kyle Tessier-Lavigne and Michael Stern, and I worked in conjunction to produce a magnetic track, levitating train car, and propulsion system. This paper focuses on my part of the project, the propulsion system. The propulsion system is similar to a linear motor, with a row of solenoids attrac...

The Briançon-Skoda theorem can be seen as an effective version of the Hilbert Nullstellensatz and gives a connection between size conditions on holomorphic functions and ideal membership. The size conditions are captured algebraically by the notion of integral closure of ideals. Many techniques have been applied to prove the Briançon-Skoda theorem and variations of it. The first proof by Brianç...

Štúdium viazania stopových prvkov v sedimente vodnej nádrže Ružín Pre účely posúdenia možnosti využitia fyzikálnych a fyzikálno-chemických metód separácie, vybraná vzorka sedimentu z Ružína bola podrobené 5-stupňovej procedúre sekvenčnej extrakcie (SE) podľa Tessiera (Tessier et al., 1979) a Horowitza (Horowitz, 1991). Vo výluhoch bolo stanovované zastúpenie konštitučných (Fe, Mn, Ca a Mg) ako ...
