By integrating data from GPS receivers with other animal-borne technologies and combining those data with additional life-history information, we believe understanding

the drivers of HPRs will inform animal ecology and improve conservation.”
“This work is focused on the evolution of structure, texture and magnetic properties in SmCo5 powders during high energy ball milling (HEBM) in heptane with and without oleic acid (OA). Single-crystal micron SmCo5 flakes were formed in the early stage of HEBM (0-0.5 h). However, HEBM of MLN2238 cell line 1-2 h without OA led to the formation of a mixture of single-crystal microflakes and loosely agglomerated polycrystalline microparticles with the highest coercivity of 15.7 kOe. HEBM of 3-5 h without OA led to the formation of isotropic, more or less equiaxed SmCo5 particles with a size of 2-30 mu m and a polycrystalline nanostructure due to the coalescence of flakes and particles. In the case of HEBM in heptane with 15 wt. % OA, prolonged milling (from 1 to 5 h) led first to the formation of SmCo5 single-crystal submicron flakes and later to submicron- and nanosize-nanocrystalline flakes with a [001]-out-of-plane texture.

OA plays an essential role in the formation of anisotropic SmCo5 flakes via the impediment of cold welding and agglomeration of flakes. The highest coercivity of 17.7 kOe was obtained in a flake sample milled for 5 h with a thickness of 8-80 nm, an average ABT263 grain size of 8 nm and an aspect ratio of 10(2)-10(3).

“Hydroquinone modified hyper-cross-linked resin (HJ-Y15) was prepared from macroporous crosslinked chloromethylated polystyrene and the adsorption behaviors of HJ-Y15 for salicylic acid were studied from aqueous solution. The results indicated that the surface of HJ-Y15 was modified by formaldehyde carbonyl, quinone carbonyl, and phenolic hydroxyl groups. Freundlich model was suitable for characterizing the isotherms and the adsorption was shown to be an exothermic, spontaneous, and more ordered selleck chemical process. The pseudosecond-order rate equation was appropriate for describing the kinetic curves and the intraparticle diffusion was the rate-controlling step. Hydrogen bonding between formaldehyde carbonyl groups of HJ-Y15 and carboxyl groups of salicylic acid was one of the primary driving forces for the adsorption. (C) 2011 Wiley Periodicals, Inc.

“We outline how principles of optimal foraging developed for diet and food patch selection might be applied to movement behaviour expressed over larger spatial and temporal scales.
