Effect of Higher Plant Essential Oils for the Control of Red Tide Algae Cochlodinium polykrikoides under Laboratory Conditions

Antialgal activity of Zataria multiflora, Satureja khuzistanica and S. rechingeri were evaluated. These plant species are easily cultivable and their algicidal activity make them suitable candidate as biocontrol. This study aimed to identify effective algicidal compounds, practically new algicidal agents from essential oils of plants that could inhibit the growth of red tide microalgae. Prepare...

Some Results on Necessary Conditions for Tow Quasidifferentiable Optimization Problems

New Necessary Conditions for

In this paper, we obtain several nonexistence results for abelian Hadamard diier-ence sets. In particular, we prove that there are no Hadamard diierence sets in abelian groups G = Z 2 Z 2 P , where jPj = p 2 , is odd and p is a prime congruent to 1(mod 4). Also we give a detailed proof for a connection between certain reversible Hadamard diierence sets and projective three-weight codes which wa...

Population dynamics of red tide dinoflagellates

Sea-surface discolorations due to high concentrations of phytoplankton are called red tides. Their ecological significance is a long standing puzzle, and they are sometimes considered pathological. Here we propose that many red tides, particularly but not exclusively those comprised of certain autotrophic dinoflagellates, are presexual/sexual swarms, essential links in their complex life cycles...

Aerosolized red-tide toxins (brevetoxins) and asthma.

BACKGROUND With the increasing incidence of asthma, there is increasing concern over environmental exposures that may trigger asthma exacerbations. Blooms of the marine microalgae, Karenia brevis, cause red tides (or harmful algal blooms) annually throughout the Gulf of Mexico. K brevis produces highly potent natural polyether toxins, called brevetoxins, which are sodium channel blockers, and p...
