Feather by exposure to emulsifying agents due to human pollution. Feathers can then become waterlogged, causing the bird to sink. It is also very difficult to clean and rescue birds whose feathers have been fouled by oil spills. The feathers of cormorants soak up water and help to reduce buoyancy, thereby allowing the birds to swim submerged. Bristles are stiff, tapering feathers with a large rachis but few barbs. Rictal bristles are found around the eyes and bill. They may serve a similar purpose to eyelashes and vibrissae in mammals. Although there is as yet no clear evidence, it has been
Calamus (DTP) LE 2015 (lite edition with restricted number of modules). Calamus is a RIP itself and handles various, adjustable raster dot sizes at the same time. It handles rasterization information per document, page or even per frame. It also uses a unique, notable method of "cutting raster dots", which means that a screen raster can be cropped or clipped at certain borders, given by the document layout elements. Thus, it does not require any external RIP for interpretation, rendering and screening of documents. Using a special module, Calamus supports dot rasterization (using the term "Star Screening") which is a frequency modulated
