The involvement of adenosine 3':5'-monophosphate (cAMP) in the regulation of the cell cycle was studied by determining intracellular fluctuations in cAMP levels in synchronized HeLa cells and by testing the effects of experimentally altered levels on cell cycle traverse. Cyclic AMP levels were lowest during mitosis and were highest during late G-1 or early S phase. These findings were supported...

Nitrate enhanced bioremediation solubility of oxygen. Nitrate is more soluble than oxygen and is less expensive. The significance of the nitrate bioremediation at Traverse City is that the concentration of nitrate used in the bioremediation was below Federal drinking water standards. that when nitrate and nutrients were added, they could be evenly distributed In order to determine the effects o...

The paper proposes a new, low area overhead Designfor-Testability (DfT) technique of Built-In Self-Test (BIST) for sequential circuits. The technique is based on making the status signals entering the control part controllable during the test mode. This requires a simple controller to manipulate these signals in order to force the device under test to traverse all the branches in the FSM state ...

Two larval foraging strategies in Drosophila melanogaster were identified, "rover" and "sitter." "Rovers" traverse a large area while feeding whereas "sitters" cover a small area. The difference between "rovers" and "sitters" was analyzed genetically by chromosomal substitutions between isogenic stocks. Differences in larval locomotor behavior ("crawling behavior") can be attributed to the seco...
