RUBBER SINK STOPPER AND OVERFLOW DRAIN FOR ROENTGEN-RAY DARK ROOM

Roentgen Ray Intoxication

These experiments show that the common laboratory animals are about equally sensitive to the x-ray given over the abdomen. The clinical reaction following a M.L.D. is very similar and the intestinal pathology almost identical. The rat and guinea pig are slightly more sensitive to the x-ray than are the dog, cat, and rabbit. By contrast birds, frogs, and reptiles are very resistant to the x-ray ...

DNA Persistence in a Sink Drain Environment

Biofilms are organized structures composed mainly of cells and extracellular polymeric substances produced by the constituent microorganisms. Ubiquitous in nature, biofilms have an innate ability to capture and retain passing material and may therefore act as natural collectors of contaminants or signatures of upstream activities. To determine the persistence and detectability of DNA passing th...

Hydraulics of Rubber Dam Overflow : a Simple Design Approach

Rubber dams have been used for the past 40 years in river and coastal engineering applications, in Australia and overseas. Despite the increasing interest for rubber dams, little information is available on their hydraulic performances. The overflow characteristics of inflated rubber dams are re-investigated. New analytical calculations provide information on the wall pressure distribution and ...
