In many vertebrate systems, early experience has been linked to the learning of speciesspecific traits that are subsequently assessed during mate choice, thus ensuring conspecific matings. In invertebrate systems, however, early experience was not thought to play a role in mate choice until a recent study using Schizocosa uetzi Stratton 1997 wolf spiders demonstrated that females mate more read...

This work aimed to improve yerba mate caffeine extraction process, considering three independent variables, carbon dioxide flow, ethanol flow and time, in levels. The following process parameters were kept constant: pressure (300 bar), temperature (60 °C), particle size (0.428 mm). Box-Behnken experimental design was carried out for 15 extractions the optimized condition obtain decaffeinated as...

In 1939, Ruth Streitz, a professor of education from The Ohio State University, wrote rather candidly of a proliferation of “canned units” in education. Units of work had been somehow interpreted to be glorified lesson packets of subject matter that could be bought and sold in somewhat of an unrestrained market. Given their relevance to contemporary problems with “modules” in technology educati...

Core network capacity planning is the process of ensuring that sufficient bandwidth is provisioned such that the committed core network service-level agreements can be met. The best practices described in this paper collecting demand matrices, determining overprovisioning factors, and running simulations are the basis of the design principles for the Cisco MATE portfolio, especially (from a pla...

This paper describes the Analyse-Organise-Synthesise methodology of multimedia development. The proposed methodology prescribes a systematic approach to developing multimedia applications. It emphasises reuse of multimedia objects and at the same time addresses quality and productivity of the development process. We illustrate our approach with examples drawn from the use of the MATE system Mul...

Several plants are used for their decorative effect during winter holidays. This review explores the toxic reputation and proposed management for exposures to several of those, namely poinsettia (Euphorbia pulcherrima), English holly (Ilex aquifolium), American holly (Ilex opaca), bittersweet (Solanum dulcamara), Jerusalem cherry (Solanum pseudocapsicum), American mistletoe (Phoradendron seroti...

We investigated the effect of nestmateship and body size on mate selection through a choice based assay in the primitively eusocial wasp Ropalidia marginata. A recent study has shown that male and female R. marginata mate with their nestmates and non-nestmates with equal probability if no choice is available. That study could also not detect any influence of body size on mating probability in t...
