They reported the permeability near the side wall is larger than that on the core region, and results in the edge effect near the side wall.
We also estimated Mayfield's (1961; 1975) nest survival rates, and nest success in relation to some variables usually used to explain variation in daily survival rates (DSR) of birds' nests using Stripe-tailed Yellow-finches as model: (a) temporal variation across the breeding season, (b) nest age, (c) nest height, (d) nest size, (e) nest substrate (plant used for nest placement), (f) edge effect, and also controlled for (g) observer effect.

The risk of a cliff edge effect on the economy and labour market should not be underestimated.
We also aimed to evaluate the underlying spatial influence on these soil characteristics due to topography and pedogenesis, and to determine if the edge effect or the spatial variation on soil properties were dominant in determining availability of nutrients in a forest fragment of the Atlantic forest in southern Brazil.
The circular profile is very efficient to completely suppress the edge effect (blue line) but it has the disadvantage of creating a higher contact pressure at the centre of the contact (695 MPa, +30% compared with the ideal contact pressure distribution).
According to Metzger and Decamps (1997), the edge effect is one of the main processes associated with fragmentation as it promotes deep changes in vegetation structure and in biological dynamics.
Otherwise, forest hosting many pionner species, which are adapted to change microclimatic conditions of the edge, may exhibit lower magnitude or distance of edge effect (Harper et al.
This HPGR is not only a larger scale version of what was currently available to the market, but also applies technological solutions to overcome some inherent concerns typically associated with traditional HPGRs, including skewing and edge effect," said Victoria Herman, product manager, HRC HPGR.
