Diatoms with their fast growth rates and obligate requirement for Si have a unique relationship to the oceanic Si cycle with the potential for controlling the nutrient and CO2 environment of large important areas of the ocean. The new production of d

A non-contact method for the measurement of a skin ulcer's area and volume has been developed. A commercially available laser displacement sensor is scanned across the ulcer's surface to produce a displacement image. From this image the healthy norma

Effective management of leg ulcer healing depends on accurate and reliable measurements of wound size. Current techniques usually rely on estimates of surface area or circumference which do not fully describe the healing process. A novel instrument h
