Toxicity of Synthetic Surfactants to the Marine Macroalga, Ulva lactuca

The toxicities of three synthetic surfactants to the marine macroalga, Ulva lactuca, have been examined by monitoring chlorophyll a fluorescence quenching. The anionic surfactant, sodium dodecyl sulphate (SDS), exerted no measurable toxicity over the concentration range 0–10 mg L, while presence of the non-ionic surfactant, Triton X-100 (TX), elicited a small reduction in photochemical efficien...

The influence of sulfathiazole on the macroalgae Ulva lactuca.

Sulfonamides (SA) are a class of antibiotics routinely found in environmental matrices and therefore their role as contaminants should be investigated in non-target organisms. With this purpose the present experimental work has evaluated the exposure of the chlorophycean Ulva lactuca L. to sulfathiazole (STZ), a SA drug commonly used in aquaculture, at two concentrations representing prophylact...

ANTIOXIDANT ACTIVITY AND ANTICARCINOGENIC PROPERTIES OF COMBINATION EXTRACT OF SOURSOP (ANNONA MURICATA LINN) AND PEARL GRASS (HEDYOTIS CORYMBOSA (L.) LAM.) (Aktiviti Antioksidan dan Antikarsinogenik daripada Ekstrak Campuran Durian Belanda (Annona Muricata Linn) dan Rumput Mutiara (Hedyotis Corymbosa (L.) Lam.)

Soursop (Annona muricata) has numerous traditional medicinal uses in South American and the Caribbean, and it has become a popular nutritional medicinal supplement. In the other hand, pearl grass (Hedyotis corymbosa (L.) Lam.) has long been used traditionally as an anti-inflammatory. In this study, soursop and pearl grass combined to obtain extracts that have anticancer effects and anti-inflamm...

Maximum Torque per Ampere Control of Permanent Magnet Synchronous Motor Using Genetic Algorithm

Pengemudian motor sinkron magnet permanen (PMSM) mempunyai banyak keuntungan dibandingkan pengemudian motor lainnya, misal efisiensi tinggi dan kerapatan daya tinggi.
