Nutritional and environmental conditions were characterized for a batch culture of the marine dinoflagellate Alexandrium tamarense HK9301 isolated from the South China Sea for its growth (cells ml ), cellular toxin content (Qt in fmol cell ) and toxin composition (mol%). Under a nutrient replete condition, Qt increased with cell growth and peaked at the late stationary phase. Toxin content incr...

Evaluation of optimal compositions of blood culture media has called for extensive and laborious work in comparative studies of large series of clincal specimens. Bacterial growth is accompanied by heat production, and calorimetry provides an analytical tool for its detection and quantification. A twin microcalorimeter of the heat conduction type was used to register heat effects in experimenta...

The effect of different chemical compositions of man-made vitreous fibers (MMVF) on their dissolution by alveolar macrophages (AM) in culture and in Gamble's solution was studied. The fibers were exposed to cultured rat AMs, culture medium alone; or Gamble's saline solution for 2, 4, or 8 days. The dissolution of the fibers was studied by measuring the amount of silicon (Si), iron (Fe), and alu...

Most sociological research assumes that social network composition shapes individual beliefs. Network theory and research has not adequately considered that internalized cultural worldviews might affect network composition. Drawing on a synthetic, dualprocess theory of culture and two waves of nationally-representative panel data, this article shows that woridvlews are strong predictors of chan...

the effect of in planta tiba and proline on in vitro seedlings and cell culture of sugar beet was investigated. sterilized seeds were grown in vitro on ½ strength ms medium supplemented with 0 or 3 mg/l tiba. calli obtained on young leaves cultured on ms medium containing 1 mg/l bap, were used for the intiation of cell suspension cultures using ms basal composition supplemented with 0 or 50 m m...
