While there has been some research on the parliamentary enclosure of upland waste in England and Wales during the eighteenth and nineteenth centuries, this topic still receives little attention in some recent accounts of parliamentary enclosure. Many aspects of the processes involved, and their impact on the landscape, are also poorly understood. Much research has proceeded either at a very gen...

The effect of enclosure design on diurnal activity and stereotypic behaviour was assessed in 17 adult Malayan Sun bears (Helarctos malayanus), kept either in barren indoor enclosures or relatively enriched outdoor enclosures. Locomotion was the most frequent activity observed in the indoor bears, followed by resting. In contrast, conspecifics housed outdoors spent most of the time resting. Elev...

Pigeons (Columba livia) searched for food hidden in the center of a square enclosure. On occasional tests without food, the enclosure was (a) unchanged from training (control tests), (b) moved to different corners of the testing room (corner tests), or (c) doubled in size (expansion tests). The birds showed localized search in the center of the enclosure on control and corner tests. On expansio...

The National Zoological Gardens of South Africa (NZG) is involved in the ex situ conservation of Gyps coprotheres, the Cape Griffon vulture (CGV) and houses 24 birds in a 100-yr-old aviary. Following the death of one vulture with high liver lead concentrations, an investigation was launched to ascertain the source(s) and consequences of lead toxicity in this breeding colony. Whole blood from 24...

Any improvement in agricultural systems that results in higher production should also reduce negative environmental impacts and enhance sustainability. The aim of this research was to investigate the effect of two different production systems, one open-field and the other shade-enclosure with four bocashi doses, in order to find the best environmental option in terms of yield, physiological and...

This report describes a low cost, shielded enclosure that was developed to contain the electromagnetic radiation generated by electronic equipment in order to reduce the potential for radio frequency interference (RFI). The enclosure is made from thin wire mesh screening that is attached to a wooden framework for support. Allowances are made at both ends of the enclosure for large cable bulkhea...

We give a short survey on methods for the enclosure of the solution set of a system of linear equations where the coefficients of the matrix and the right hand side depend on parameters varying within given intervals. Then we present a hybrid method for finding such an enclosure in the case that the dependency is polynomial or rational. A general-purpose parametric fixed-point iteration is comb...

Several recent studies have shown that chickens, fish, and humans trained to find a reward in a corner of a rectangular enclosure with distinctive features rely more on the geometry of the enclosure in small enclosures and rely more on the features in large enclosures. Here, these results are modeled using a recent associative model of geometry learning [Miller, N.Y., Shettleworth, S.J., 2007. ...

The Dodewaard NPP was shut down in 1997 and is now in the decommissioning phase. All spent fuel has been removed from the plant and transferred to Sellafield, in the United Kingdom, for reprocessing. The last shipment of spent fuel from Dodewaard was made in April 2003. In May 2002 a license was granted to GKN, the operator of the NPP Dodewaard, to bring and keep the plant in a safe enclosure. ...
