long-distance dispersal of the coconut palm by migration within the coral atoll ecosystem.the location of the original home of the coconut palm, cocos nucifera, and the extent of its natural dispersal are not known. proponents of a south american origin must explain why it is not indigenous there and why it shows greatest diversity in southern asia. conversely, proponents of an asian origin must explain why there are no asian cocoseae and why the closest botanical relative to cocos is in south america. both hypotheses share the common problems of how, when, where and in what directio ...201424368197
the presence of coconut in southern panama in pre-columbian times: clearing up the confusion.the pre-columbian presence of coconut on the pacific coast of panama is attested by a number of independent written accounts. however, recent papers question their accuracy and conclude that coconut was introduced to the region by the spaniards after their conquests. scope in order to examine the value of such claims, an extensive search was conducted of the relevant historical accounts of coconut in america and in the orient.201424227445
use of coir pith particles in composites with portland cement.brazil is the fourth largest world's producer of coconut (cocos nucifera l.). coconut crops generate several wastes, including, coir pith. coir pith and short fibers are the byproducts of extracting the long fibers and account for approximately 70% of the mature coconut husk. the main use of coir pith is as an agricultural substrate. due to its shape and small size (0.075-1.2 mm), this material can be considered as a particulate material. the aim of this study was to evaluate the use of coir pit ...201324184526
interaction of cocos nucifera cream casein with humic acid suspensions.two caseins labelled as casmg (casein without fats) and camg (casein with fats) were extracted from coconut cream. both caseins were used as coagulants for the aggregation of humic acid (ha) particles in synthetic water at ph = 6 during the jar-test essays. the optimum dosage of camg or casmg and the residual turbidities of treated water obtained depend on the type of used casein (camg or casmg) and the concentration of particles in solution. the optimal doses of camg and casmg are respectively ...201222699339
