A Plastic Clock

Most organisms have internal circadian clocks that anticipate the daily environmental changes at dawn and dusk and drive 24 hr rhythms in behavior and physiology. We are usually only aware of our internal clocks when they become desynchronized from the environment during jetlag, but these clocks are impressively accurate and run with periods close to 24 hr even in constant darkness. Genetic scr...

Cell Timer/Cell Clock

Like the biological clock in the body, replication of each cell type (even different cells of the same organism) follows a timing program. Abnormal function of this timer could be an alarm for a disease like cancer. DNA replication starts from a specific point on the chromosome that is called the origin of replication. In contrast to prokaryotes in which DNA replication starts from a single ...

FlexClock, a Plastic Clock Written in Oz with the QTk toolkit

This paper focuses on the techniques involved in building an interactive application using a plastic user interface. These techniques take advantage of the QTk toolkit, a toolkit that features innovative and powerful concepts when compared to more classical object-oriented toolkits. These features are possible thanks to the underlying programming language used, Oz, and in particular: a. its sup...

A CLOCK-less clock.

Mammalian physiology is governed by a complex circadian timing system that involves interacting positive and negative transcriptional feedback loops. A key role in this feedback loop was attributed to the PAS domain helix-loop-helix protein CLOCK, on the basis of a dominant-negative mutation in this transcription factor. However, recent experiments by Reppert and coworkers with Clock knockout m...

A plastic catheter mount.

Among the disadvantages of catheter mounts in common use is that, as generally manufactured, they have sharp interior angles militating against laminar flow. The diagram illustrates the longitudinal section of a plastic variant in which the narrowing has been chamfered off. It has been found satisfactory in practice, and seems to be standing up robustly to use. It has the additional advantage o...
