Cross-phase modulation effects in normal dispersive fibers and their applications
2018
In this Ph.D., physical effects arising from cross-phase modulation between twoorthogonally polarized signals propagating in normal dispersion fibers arestudied and some of their applications investigated.First, a 40-GHz pulse generator is designed by sending two orthogonallypolarized out-of-phase sinusoidal waves in a normally dispersive optical fiber.A large power imbalance between the two waves induces a periodic phasepotential for the weak replica which turns the normal dispersive defocusingregime into a focusing dynamics, thus compressing the sinusoidal wave intoshort and well-separated pulses.A signal sampler and magnifier was then designed using the same principle,sending a high powe…
Etude des mécanismes physiologiques et moléculaires permettant la prise en charge des substrats hydrophobes par la levure Yarrowia lipolytica au nive…
2012
Yarrowia lipolytica can grow on many hydrophobic substrates and metabolize them via the β-oxidation pathway or store them into lipid bodies. The first contact between the cell and the hydrophobic substrates is by the cell wall. In this step, cell-wall proteins (CWP), β-glucane and chitin of the cell wall could play an important role for the adhesion and uptake of hydrophobic substrates. The aim of this work was to study the effect of a hydrophobic carbon source (compared with glucose) and the culture medium composition on the cell wall composition and the melanin production by Y. lipolytica. The results of our biochemical and molecular analysis showed that the presence of methyl oleate and …
Rbt1 Protein Domains Analysis in Candida albicans Brings Insights into Hyphal Surface Modifications and Rbt1 Potential Role during Adhesion and Biofi…
2013
Cell wall proteins are central to the virulence of Candida albicans. Hwp1, Hwp2 and Rbt1 form a family of hypha-associated cell surface proteins. Hwp1 and Hwp2 have been involved in adhesion and other virulence traits but Rbt1 is still poorly characterized. To assess the role of Rbt1 in the interaction of C. albicans with biotic and abiotic surfaces independently of its morphological state, heterologous expression and promoter swap strategies were applied. The N-terminal domain with features typical of the Flo11 superfamily was found to be essential for adhesiveness to polystyrene through an increase in cell surface hydrophobicity. A 42 amino acid-long domain localized in the central part o…

Paroimijas Sudas leksikonā: forma un jēdzieniskais saturs
2020
Maģistra darba Paroimijas Sudas leksikonā: forma un jēdzieniskais saturs mērķis ir izpētīt Sudas leksikonā atrodamo paroimiju struktūru, saturu un pielietojumu. Darba ietvaros ir mēģināts izveidot sengrieķu paroimijas definīciju, kas ietver gan saturisko, gan strukturālo aspektu. Maģistra darbs sastāv no trim nodaļām – Paroimija, Paroimijas statuss un struktūra, Paroimijas Sudas leksikonā. Darba teorētiskajā daļā aplūkotās antīko autoru atziņas par paroimijas saturu ir papildinātas ar mūsdienu zinātnieku paroimijas struktūras analīzi, kā arī ir apskatīta paroimijas definēšanas un tulkošanas problemātika. Praktiskajā daļā ir analizētas lemmas, kuru pamatā ir kādas paroimijas, kas tiek skaidr…
