Climatic and anthropogenic changes are able to engender modifications in the aerosol composition at different geographical and temporal scales. The present study addresses this question for the trace metal concentrations (TM=Al, Fe, Mn, Co, Ni, Cu, Pb, Cd and Zn) of aerosol from the North-western Mediterranean coast of France (Cap Ferrat, nearby Nice) between 1986 and 2008. From seasonal variat...

In fragmented tropical landscapes, among the most pervasive causes of ecological change are edge effects diverse ecological alterations associated with the abrupt, artificial boundaries of forest fragments (Laurance & Bierregaard 1997, Lovejoy et al. 1986, Turner 1996). A striking edge effect in fragmented Amazonian forests is chronically elevated tree mortality (Ferreira & Laurance 1997, Laura...

There are many studies for generating irreducible polynomials (L. M. Adleman & H. W. Lenstra (1986)) − (Ian. F. Blake et al., (1993)). This is because irreducible polynomials play critical roles in the cases such as constructing extension field or generating random sequence. The problem of generating irreducible polynomial is theoretically interesting and have attracted many scientists and engi...

Simultaneous pre- and postsynaptic intracellular recordings, combined with HRP injections, were used to study the properties of junctional transmission between club endings of saccular nerve afferents and the Mauthner (M-) cell in goldfish. All endings were electrotonically coupled to the M-cell, but impulses in less than 20% of the afferents produced chemically mediated excitatory postsynaptic...

Fallen woody debris, standing dead trees (taller than 1.3 m) and stumps (shorter than 1.3 m) constitute a large portion of total above-ground carbon in tropical and temperate forests (Keller et al. 2004; Rice et al. 2004). In addition to being an important carbon pool, aboveground necromass is important in nutrient cycling, water retention, fuel load, and as resources for many organisms. Despit...
