(TED-GC鈥揗S), the adsorption behaviour, ageing in drainage water and soil, their transport behaviour in lysimeters, ecotoxicity, uptake in plants, a life cycle assessment (LCA) and upcycling were considered.The PE film tested showed hardly any degradation or fragmentation during the ageing ...
Mechanism of Production of Candida Lesions in Rabbits Proliferation of large monocytes was responsible for fragmentation and destruction of the fungus in all the tissues except the spleen, where there was complete absence of reaction although fungal cultures were positive. The fungus was ... VN Damod...

Differences in home range size and foraging strategies may explain whyunderstoreyfruit bat species are more sensitive to fragmentation than canopy ones. Such a level of illumination is only experienced in theunderstoreyduring brief sunflecks.

The choice of a location is one of the most important decisions taken by an enterprise, both at start-up and at other stages of its life cycle involving a relocation of activity or a spatial fragmentation of the chain of value-added generation. The choice of a location by an enterprise is...

Seagrasses are submerged marine plants that have been declining globally at increasing rates. Natural resource managers rely on monitoring programs to detect and understand changes in these ecosystems. Technological advancements are allowing for the development of patch-level seagrass maps, which can be ...
Proposed reaction mechanism for the MC destruction of 6:2FTS. Full size image The second step is the fragmentation of the 2-ene-compound by homolytic rupture of C3‒C4bond, probably induced by OH−. Since PFPeA is the observed intermediate with the longest chain, it is inferable that th...
