Rotifers are widely used in hatcheries to feed small-sized aquatic larvae although one of their disadvantages is the lack zinc and selenium 5- 30-fold lower than copepods, respectively. To improve rotifers quality, different concentrations (2, 4, 5 10 mg L−1 each mineral) were added medium microalgae Isochrysis aff. galbana Nannochloropsis oculata for 4 days, then harvested concentrated rotifer...

The need to replace petroleum fuels with alternatives from renewable and more environmentally sustainable sources is of growing importance. Biomass-derived biofuels have gained considerable attention in this regard, however first generation biofuels from edible crops like corn ethanol or soybean biodiesel have generally fallen out of favor. There is thus great interest in the development of met...

Clearance rate (CR) and ingestion rate (IR) of different sizes (89, 125 and 188 lm shell length) of Pinctada margaritifera larvae were determined when feeding on various microalgae. The microalgae tested were the diatoms, Chaetoceros muelleri and C. simplex, and flagellates, Tahitian Isochrysis aff. galbana, Pavlova lutheri and P. salina at 5 or 10 cells lL. Both CR and IR of microalgae tested ...

Lipids were extracted from Isochrysis galbana using a microwave-assisted method accompanied by various types of organic solvents. The effects of organic solvent type and microwave input energy on the fatty acid characteristics of the extracted lipids and their biodiesel product were investigated. Variations in the characteristics of the lipids extracted using a combination of n-hexane and iso-p...

This paper deals with the application of electrolysis technology for the selective control of marine algal species. The sensitivity of different marine algal species to electrolysis may be different due to their size and structural differences. Electrolysis experiments were conducted using four algal species, namely Chlorella spp., Chaetoceros spp., Isochrysis spp. and Tetraselmis spp. Batch an...

For $\mathfrak g$ a Kac-Moody algebra of affine type, we show that there is an $\text{Aut}\, \mathcal O$-equivariant identification between $\text{Fun}\,\text{Op}_{\mathfrak g}(D)$, the functions on space ${\mathfrak g}$-opers disc, and $W\subset \pi_0$, intersection kernels screenings inside vacuum Fock module $\pi_0$. This kernel $W$ generated by two states: conformal vector, state $\delta_{-...

PURPOSE To determine the extent that auditory force feedback (AFF) substitution improves performance during a simulated ophthalmic peeling procedure. METHODS A 25-gauge force-sensing microforceps was linked to two AFF modes. The "alarm" AFF mode sounded when the force reached 9 mN. The "warning" AFF mode made beeps with a frequency proportional to the generated force. Participants with differ...

This study evaluates the nutritional value of several species of freeze-dried microalgae used to feed the seed of Ruditapes decussatus. These microalgae were: Isochrysis galbana, clone T-ISO; Tetraselmis suecica; and Phaeodactylum tricornutum. The addition of antibiotics, kaolin and fresh microalgae to the freeze-dried diet was also evaluated, and a study was made of the nutritional value of on...
