Finally, we shall

examine whether such future-oriented behaviour involves future planning and ask why this and other cognitive abilities might have evolved in corvids.”
“This study examined the effects of the incorporation of carbon fiber (CF) and silicon carbide powder (SCP) into a high temperature vulcanized (HTV) silicone rubber, poly(dimethylsiloxane) (PDMS) containing vinyl groups on the ablation properties using an oxy-acetylene torch test. The ablation test results showed that CF enhanced the hardness of the char formed on the composite surface during the oxy-acetylene torch test and was an important factor determining the ablation properties. GS-9973 inhibitor SCP was also beneficial in enhancing the surface char hardness of the HTV/CF composite. A new method was devised to evaluate the ablation properties more objectively by measuring the time elapsed for a rectangular-shaped silicone rubber composite with specimens loaded with a constant weight to burn and fail off during the oxy-acetylene torch test. The mechanical properties of the

silicone rubber composites were also examined as a function of the additive content using a universal test machine (UTM). (C) 2010 Wiley Periodicals, Inc. J Appl Polym Sci 120: 831-838, 2011″
“We explore the behavior of periodic arrays of magnetic nanowires by micromagnetic simulations using the NMAG modeling package. A large number of modeling studies on such arrays of nanowires have been performed using finite size models. We show that these finite size micromagnetic descriptions can only be used in specific situations. We perform a systematic study selleck products of more or less dense one-and two-dimensional

arrays of nanowires using either finite size or infinite size models and we show that finite size models fail to capture some of the features of real infinite systems. We show that the mean field model scaled to the system S63845 cell line porosity is valid. This work can be used as a basis to the extension of micromagnetic calculations of the magnetization dynamics in arrays of nanowires. (C) 2011 American Institute of Physics. [doi:10.1063/1.3518498]“
“Some plants that are dispersed by scatter-hoarding animals appear to have evolved the ability to manipulate the behaviour of those animals to increase the likelihood that seeds and nuts will be stored and that a portion of those items will not be recovered. Plants have achieved this in at least four ways. First, by producing large, nutritious seeds and nuts that are attractive to animals and that stimulate hoarding behaviour. Second, by imposing handling costs that cause animals to hoard rather than to eat items immediately. These handling costs can take one of two forms: physical barriers (e.g. hard seed coats) that take time to remove and secondary chemicals (e.g. tannins) that impose metabolic costs.
