Temporal variations, both intra- and interannual, in swimmer flux

Temporal variations, both intra- and interannual, in swimmer fluxes were high (26 to 361 ind. m(-2) d(-1)), but not all groups/taxa/species were equally affected. Statistical

analyses showed that these variations were the result of variability in both physical (near-bottom current) and trophic (particle flux) environmental factors. Organisms had both immediate and delayed responses, which involved passive (i.e. erosion, suspension) and active (i.e. emergence) reactions, as well as population growth. Most of the dispersal mechanisms previously reported for shallow-water benthic organisms were encountered, denoting the remarkable similarities in the general processes between coastal and deep-sea environments.”
“Eating disorder during pregnancy is associated with a diversity of adverse outcomes and is of potential danger to both mother and child. There is, however, a tendency for remission of the eating disorder during pregnancy with find more improvement of symptoms such as restrictive dieting, binging Raf inhibitor and purging, and some women actually manage to put the disease behind them. This case report describes five women with different eating disorders and focuses on the symptomatology during pregnancy and in the months postpartum. The discussion

deals with the possible psychological, social and endocrinological reasons for remission and the subsequent relapse, the definition of recovery and the factors which should alert health care professionals of the at-risk pregnancies

in cases of undisclosed eating disorder. Furthermore, therapeutic interventions are proposed.”
“A series of YAB:Eu3+/Tb3+ co-activated selleckchem phosphors of composition Y(1-x-y)Al3(BO3)(4)xEu(3+)/yTb(3+) (x=0, 0.3, 0.5, 1, 2% and y=0.5%) were prepared by solid-state reaction method and their photoluminescence properties were characterized. Eu3+/Tb3+ co-doped phosphors have shown their excellent luminescent properties in their respective emission regions. The YAB:2%Eu3+ phosphor under 395 nm excitation exhibited red luminescence with Commission International de I’Eclairagein chromaticity coordinates (x=0.627, y=0.334) which are close to an ideal red and commercial Y2O3:Eu3+ red phosphor chromaticity coordinates. The emission color of Eu3+/Tb3+ co-doped phosphors has been tuned from pale-green to white as a function of Eu3+/Tb3+ concentration. Moreover, the Tb3+ acts as an efficient sensitizer and enhances the luminescence of Eu3+ by transferring absorbed excitation energy. The overlapping F-7(0)- bigger than D-5(3,2,1,0) (Eu3+); F-7(1)- bigger than bigger than D-5(1,0)(Eu3+); F-7(2)- bigger than D-5(1)(Eu3+) excitation and D-5(3)- bigger than F-7(5,4,3) (Tb3+); D-5(4)- bigger than F-7(5,4)(Tb3+) emission transitions revealed the transfer of energy from Tb3+ to Eu3+ through exchange interaction mechanism in Eu3+-Tb3+ clusters instead of from these ions randomly distributed in YAB lattice. The YAB:Eu3+/Tb3+ phosphors have potential in the field of display technology.
