This study compared the growth and biomass production of Isochrysis galbana under hetero-, mixo-, and phototrophic conditions using different organic carbon sources. The growth of I. galbana was inhibited in heterotrophy but was enhanced in mixotrophy compared to that in phototrophy. Subsequently, the influences of organic carbon and environmental factors (light and salinity) on the growth of I...

Large epidemiological databases are often used to examine matters pertaining to drug utilization, health services, and drug safety. The major strength of such databases is that they include large sample sizes, which allow precise estimates to be made. The IMS® LRx database has in recent years been used as a data source for epidemiological research. The aim of this paper is to review a number of...

It has been a great honor to represent you dur ing this last year, and it is a great challenge to stand before you now. Table I presents some of the multiple titles I have considered for this pre sentation over the last 10 months. I had a diffi cult time, in early August, when I had to select a final topic and fax my actual title to the Sci entific Program Chair, Bill Petri. I originally though...

Historically, all basic mathematical concepts of control theory were first stated and developed in continuous time, and subsequently reformed for discrete time, motivated by the growing role of digital computations and computer use. Although a majority of notions and results for continuousand discrete-time systems are almost identical, these two branches of the control science have been develop...

Compliance with malaria chemoprophylaxis programmes was studied in the National Railways and two large commercial farm labour forces in Zimbabwe. Prophylaxis was primarily conducted using pyrimethamine/dapsone and the study measured compliance rates through interview and the detection of drug in the urine. Compliance rates as indicated from registers or questioning were not always reliable and ...

I HE J. H. Ames School, a labora tory school at Wisconsin State University in River Falls, completes a third year of use of hand-designed modular scheduling this year. Planning and implementation of this mode of education involved 100 students, grades six through nine. Instructional re sources and building facilities available dur ing this period could be considered adequate to superior, but we...

It has been well documented that nutritional state can influence the foraging behavior of animals. However, photosynthetic animals, those capable of both heterotrophy and symbiotic photosynthesis, may have a delayed behavioral response due to their ability to photosynthesize. To test this hypothesis we subjected groups of the kleptoplastic sea slug, Elysia clarki, to a gradient of starvation tr...

Effects of the antimicrobial agent triclosan to natural periphyton communities (biofilms, comprising primarily microalgae and bacteria) were assessed in two independent experiments during spring and summer. For that purpose a semi-static test system was used in which periphyton was exposed to a concentration range of 5-9054 nmol/L triclosan. Effects on algae were analyzed as content and composi...
