Single-molecule experiments have been helping us to get deeper inside biological phenomena by illuminating how individual molecules actually work. Digital bioassay, in which analyte are individually confined small compartments be analyzed, is an emerging technology single-molecule biology and applies various entities (e.g., cells virus particles). However, digital bioassay not compatible with m...

Electro-optical devices are increasingly used for military sea-, landand air applications to detect, recognize and track objects. Typically, these devices produce video information that is presented to an operator. However, with increasing availability of electro-optical devices the data volume is becoming very large, creating a rising need for automated analysis. In a military setting, this ty...

The concentrations in the air of total and of respirable (less than 7 microns equivalent diameter) dust were measured in 142 workrooms of 17 Northern Ireland flax spinning mills using a hexhlet air sampler. Neither the distribution of total nor of respirable dust concentrations (mg./100 m.3 air) measured in each of four large workrooms conformed to the normal (or Gaussian) distribution, but it ...

The removal of bacterial populations from large volumes of liquid culture media may be accomplished readily using a centrifuge, but the usual efficient continuous-feed type of centrifuge is often large and expensive. In this laboratory, during the past 2 years, bacterial cells have been removed from liquid culture with considerable success, using a small, inexpensive, continuously fed centrifug...

The didgeridoo is a wind instrument composed of a single large tube often used as drone instrument for backing up the mids and lows of an ensemble. A didgeridoo is played by buzzing the lips and blowing air into the didgeridoo. To play a didgeridoo continously one can employ circular breathing but the volume of air required poses a real challenge to novice players. In this paper we replace the ...
