The feeding dynamics and oxygen uptake of the bottom-dwelling caridean shrimp Nauticaris marionis were studied during the April/May 1984, 1996 and 1997 cruises to Marion Island (Prince Edward Islands, Southern Ocean). N. marionis is thought to have an opportunistic feeding mode. Prey composition varied considerably between the years and sites investigated.(More)
The structure and grazing dynamics of the protozooplankton community at ten stations in the upstream and downstream region of the Prince Edward Islands (46°38′S, 37°57′E) were investigated during early austral autumn (April/May) 1997. Total chlorophyll-a (chl-a) concentrations throughout the investigation were <0.6 μg l−1 and were always dominated by nano-(More)
FT-IR spectra, in the frequency region 4000-600 cm(-1), of four major lipoprotein classes: very low density lipoprotein (VLDL), low density lipoprotein (LDL) and two subclasses of high density lipoproteins (HDL(2) and HDL(3)) were analyzed to obtain their detailed spectral characterization. Information about the protein domain of particle was obtained from(More)
Fourier transform infrared (FT-IR) spectra of human spermatozoa and seminal plasma were recorded and analyzed. The procedure that was established for sample preparation enabled acquisition of reproducible spectra. The parameter I(1087)/I(966) for controlling spectra reproducibility was defined. The assignment of bands was carried out using an empirical(More)
Porous silicon (PSi) samples were prepared by electrochemical anodisation of silicon on insulator layers. Structural and optical properties of prepared samples were investigated by Raman and photoluminescence (PL) spectroscopy and field emission scanning electron microscopy (FE-SEM). The anodisation of silicon on insulator layers was performed by(More)
Silicon epitaxial wafers, consisting of 280 μm thick n-type substrate layer and 4–5 μm thick epitaxial layer, were electrochemically etched in hydrofluoric acid ethanol solution, to produce porous silicon samples. The resistivity of epitaxial layer was 1 Ω cm, while the substrate was much better conductor with resistivity 0.015 Ω cm. By varying the etching(More)
FT Raman spectroscopy has been applied to determine the location of PRODAN within HDL and to investigate its influence on the structure of the particle. The complex spectra of HDL and HDL labeled with PRODAN were divided into three regions according to the wave numbers, and adherent spectra were compared separately. Additionally, recorded spectra of protein(More)
The Si-rich silicon oxide (SiOx) thin films are prepared on silicon crystalline substrates by low pressure chemical vapor deposition (LPCVD) method. The oxygen concentration x are controlled by the ratio of the partial pressures of N2O and SiH4 gases in the reaction chamber. In order to induce the phase separation on SiO2 and Si nanostructures the samples(More)
