a r t i c l e i n f o Keywords: Marine snow Aggregates Biogeochemistry Density gradients Density interfaces Fluid dynamics Marine snow aggregates are often a dominant component of carbon flux and are sites of high bacterial activity; thus, small-scale changes in the settling behavior of marine snow can affect the vertical locations of carbon export and remineralization in the surface ocean. In ...

Given a polynomial of degree d over number field, the image associated arboreal representation absolute Galois group field is profinite acting on d-ary tree. Boston and Jones conjectured that for quadratic polynomial, such contains dense set settled elements. Here an element if it exhibits certain pattern growth cycles at finite levels In this paper, we prove conjecture generically in case when...

The Taguchi method was applied as an experimental design to determine optimum conditions for colour removal from azo dyes solutions containing remazol yellow G by electrocoagulation (EC) using iron and steel electrodes as anode and cathode, respectively. An orthogonal array (OA9) experimental design that allows to investigation the simultaneous variations of four parameters (initial remazol ye...

Understanding how the density and spatial arrangement of invaders is critical to developing management strategies of pest species. The Pacific oyster, Crassostrea gigas, has been translocated around the world for aquaculture and in many instances has established wild populations. Relative to other species of bivalve, it displays rapid suspension feeding, which may cause mortality of pelagic inv...

The morphological distribution of primordial density peaks is assessed. Previous determinations, those of Peacock & Heavens (1985) and those of Bardeen et al. (1986) have contradictory concluded that there exist a tendency towards prolate or towards oblate shapes, respectively. By using two methods, the Hessian and the inertia tensor momenta we have performed numerical determinations of the tri...
