Automated Thermoluminescence Reader Ii. Experiments and Theory

Charge recombination and thermoluminescence in photosystem II.

In the recombination process of Photosystem II (S(2)Q(A)(-)-->S(1)Q(A)) the limiting step is the electron transfer from the reduced primary acceptor pheophytin Ph(-) to the oxidized primary donor P(+) and the rate depends on the equilibrium constant between states S(2)PPhQ(A)(-) and S(1)P(+)Ph(-)Q(A). Accordingly, mutations that affect the midpoint potential of Ph or of P result in a modified r...

Discourse Theory and the Author-Reader Contract:

The change of the mode of narration from first person in the drafts to third person in the final version of Dostoevsky's novel Crime and Punishment has received surprisingly little attention from either literary critics1 or linguists. Yet the first-person drafts contain episodes depicting the same events as in Dostoevsky's final text, providing perfect laboratory conditions for exploring both t...

An inexpensive semi-automated sequence reader for the Apple II computer

We describe a relatively inexpensive digitizing pad, available from Houston Instruments, for which we have written software which allows the direct reading of DNA (or RNA) sequencing gel autoradiographs. This eliminates several sources of error in nucleic acid sequencing, and renders computer analysis less cumbersome.

Upgrading a microplate reader for photobiology and all-optical experiments.

Automation can vastly reduce the cost of experimental labor and thus facilitate high experimental throughput, but little off-the-shelf hardware for the automation of illumination experiments is commercially available. Here, we use inexpensive open-source electronics to add programmable illumination capabilities to a multimode microplate reader. We deploy this setup to characterize light-trigger...
