Analyses of gardens are commonly encountered through plan and perspective views only – as if a garden in situ might be replaced by its representation in plan, and as if the actual experience of a garden is limited to a succession of views. Yet, walking in the garden (any garden) is a much richer experience than simply encountering a succession of framed views. Being spatial environments, gardens are perceived and explored by looking, feeling, walking visitors. The graphical explorations in this essay are an attempt to explore the components and underlying structure of the spatial experiences inherent in any designed space. [less ▲]

Background: Derivative based a-priori structural identifiability analyses of mathematical models can offer valuable insight into the identifiability of model parameters. However, these analyses are only capable of a binary confirmation of the mathematical distinction of parameters and a positive outcome can begin to lose relevance when measurement error is introduced. This article presents an integral based method that allows the observation of the identifiability of models with two-parameters in the presence of assay error. Methods: The method measures the distinction of the integral formulations of the parameter coefficients at the proposed sampling times. It can thus predict the susceptibility of the parameters to the effects of measurement error. The method is tested in-silico with Monte Carlo analyses of a number of insulin sensitivity test applications. Results: The method successfully captured the analogous nature of identifiability observed in Monte Carlo analyses of a number of cases including protocol alterations, parameter changes and differences in participant behaviour. However, due to the numerical nature of the analyses, prediction was not perfect in all cases. Conclusions: Thus although the current method has valuable and significant capabilities in terms of study or test protocol design, additional developments would further strengthen the predictive capability of the method. Finally, the method captures the experimental reality that sampling error and timing can negate assumed parameter identifiability and that identifiability is a continuous rather than discrete phenomenon.

Cet article traite de la passation graphique d'une intention et révèle, par l'intermédiaire d'expérimentations ciblées, quels composants graphiques soutiennent particulièrement bien ou mal cette passation. Les résultats suggèrent d'apporter une attention toute particulière, que l'on soit concepteur-collaborateur ou développeur d'interfaces de soutien à la collaboration distante, aux courbes dites "principales". Celles-ci semblent effectivement être garantes d'une intention graphique potentiellement mieux transmise et mieux capturée - l'essence graphique d'une collaboration distante efficace. [less ▲]

Some trials with graphite Hi-Cr iron rolls have been done mainly in Japan, for the rolling of stainless steel. This material could lead to good compromise between oxidation, wear and thermal behaviour. By using thermal analysis and resistometry, the conditions for secondary graphite formation have been studied. The amount and volume of free graphite may be strongly increased by a suitable heat treatment, allowing a good thermal conductivity as well as high wear and mechanical properties. [less ▲]

The management of grassed buffer strips proved to be an efficient remediation technique in controlling nitrogen losses to surface water. In south Belgium, agri-environmental policies have encouraged farmers to seed buffer strips along rivers, in zones where the soil was previously devoted to agricultural production. We wanted to assess how important denitrification is in a buffer strip in comparison with a cropped field. The study investigated the denitrifiying enzyme activity (DEA) of two contiguous buffer strips with different management stories. The eastern part of the buffer strip was seeded in 1999. The western part of the buffer strip is a piece of crop field abandoned by the farmer 20 years ago and not managed for the last 10 years. This experimental study demonstrates that the denitrification enzyme activity in a riparian buffer strip is significantly higher than in the adjacent cropped field (3.67 and 2.12 mgNkg(-1)d(-1) respectively). The DEA was significantly different between the two buffer strips under comparison, assessing that the management of the buffer strips has a dominant effect on DEA. The old unmown buffer strip is potentially more efficient in the nitrate removal process than the 6-year-old seeded buffer strip. [less ▲]

Rising economies and rapid urbanization in developing countries, particularly in Asia, are creating shifts in the composition of global food demand, so it is necessary to explore new sources of food with better nutritional profile. Among the alternative food that exists are the grasshoppers, about 80 species of which are consumed worldwide. Grasshoppers are not only rich source of proteins and lipids but also some important minor component like vitamins and minerals. Apart from being nutritionally superior to most conventional meats their production results in lower emission of greenhouse gases & ammonia, risk of zoonotic infections in humans is much lower, water requirement for production is much less and have higher feed conversion ratio. Edible species of grasshopper in Belgium were identified, attempts were made for the lab rearing of meadow grasshopper (Chorthippus parallelus) and fat as well as protein contents of meadow grasshopper (Chorthippus parallelus) & long winged conehead (Conocephalus discolor) were investigated.

The classical Rayleigh quotient iteration (RQI) allows one to compute a one-dimensional invariant subspace of a symmetric matrix A. Here we propose a generalization of the RQl which computes a p-dimensional invariant subspace of A. Cubic convergence is preserved and the cost per iteration is low compared to other methods proposed in the literature. [less ▲]
