[The study] recommends the use of stage-structured models in which stages are embedded within age classes. This effectively increases the number of stages in a model. Such a population matrix can be constructed if one collects information on the stage of individuals in addition to age in order to construct a life table in which individuals are categorized into different age and stage classes. This approach is also useful when life history strategies are complex or when they do not exhibit age-dependent changes in vital rates.

CONT

Contact leaching paint, also known as hard-racing or long-life paints, are also free-association types but have an insoluble matrix. Continuous biocide release is generated by the high biocide concentration ensuring that biocide particles contact each other through the paint film. As surface biocide is released, microchannels are created which permit release of biocide from deeper in the coating. Biocide release rates decrease exponentially with time and effective life is again limited to periods rarely exceeding 18 months.

CONT

The products with a low level of rosin are hard and are referred to as contact leaching antifoulings. They are mechanically tough, have no polishing characteristics and commonly have a maximum in-service lifetime of 24 months (depending on in-service conditions and specification applied).

Subject field(s)
  • Computer Display Technology
DEF

A type of passive matrix LCD(Liquid Crystal Display) that provides faster refresh rates than conventional passive matrix displays by dividing the screen into two sections that are refreshed simultaneously.

OBS

Dual scan displays are generally not as sharp or bright as active matrix displays, but they consume less power.

OBS

Type of passive-matrix display found with portable computers and flat panel displays. A dual-scan display refreshes twice as often as the regular passive-matrix.
