Filling-in refers to the tendency of stabilized retinal stimuli to fade and become replaced by their background. This phenomenon is a good example of central brain mechanisms that can selectively add or delete information to/from the retinal input. Importantly, such cortical mechanisms may overlap with those that are used more generally in visual(More)
This paper describes the most common methods for recovery of chitin from crab shell. Deproteinization, demineralization and deacetylation are the main processes for the extraction of chitin and chitosan. The mechanical properties were investigated to recognize their mechanical applications. Chitin is the most widespread biopolymer in nature, after(More)
