SATRA Technology wishes to use an “artificial foot” to replace those of live volunteers in comfort tests. The artificial foot has the size and shape of a real foot and is made of a heated aluminium core surrounded by a polyurethane and a porous-rubber layer. The tests involve equipping the artificial foot with hose (socks, stockings, etc.) and the shoes or boots to be tested, and subjecting it ...

Selective breeding of rohu, Labeo rohita to Aeromonas hydrophila infection requires a challenge model to obtain LD50 dose and study of bacterial persistence in survivors’ tissues. Fish were bath challenged with various routes viz., only immersion, after scale removal (with and without high stocking), after skin abrasion (with and without high stocking), under only high stocking density and afte...

Influence of three different stocking densities, vitamin C supplementation of Daphnia spp. and feeding practice (i.e. mechanical, hand) on the success of dry feed habituation of pond reared pikeperch juveniles was investigated through one month trial. Pond reared pikeperch juveniles were harvested 42 days post-fertilisation (mean individual weight 1.1 ± 0.3g) and stocked into the experim...

Alfalfa (Medicago sativa L.) persistence and forage and cow-calf production were evaluated on pastures containing smooth bromegrass with or without grazing-tolerant or hay-type alfalfa cultivars rotationally stocked in either a season-long or complementary system. In 1997, six 2.02-ha pastures were seeded with smooth bromegrass, a mixture of a grazing-tolerant alfalfa (Amerigraze variety) and s...

Human infections with Salmonella Enteritidis are often attributed to the consumption of contaminated eggs, so the prevalence of this pathogen in egg-laying poultry is an important public health risk factor. Numerous and complex environmental influences on Salmonella persistence and transmission are exerted by management practices and housing facilities used in commercial egg production. In rece...

Quantitative relationships between stand indices and carbon dioxide (CO2) stocking are missing in the evergreen broadleaved forests (EBLFs) in eastern China and this hinders to estimate carbon (C) budget in the subtropical region. We determined the vegetation-soil C pool and CO2 stocking using stand indices [diameter at breast height (DBH), total height (H) and wood density] in Schima superba d...

In a previous paper (Illius et al., 1998), we analysed the potential of tracking strategies to increase output under climatic variability. Regrettably, an error in the processing of data on the annual variability of sales led us to the wrong conclusions about the usefulness of tracking policies in smoothing inter-annual variation. This note presents corrections. Our conclusions about the genera...
