A retrospective study evaluated 75 total hip arthroplasties performed over a 4-year period using 4 different cement restrictors. A harvested bone restrictor, polyethylene restrictor (Smith & Nephew, Richards Inc, Memphis, Tenn), Biostop G (Depuy Orthopaedics, Warsaw, Ind), and polymethylmethacrylate (PMMA) (Wright Medical Technology, Arlington, Tex) were compared for the percentage of failures,...

We present an evaluation of the laser ablation Sr isotope data reported by Richards et al. (2008) for a Neanderthal tooth recovered from a site in Greece. Based on an alternative and analytically more robust method of correcting for isobaric interferences present during the analysis the tooth appears to be isotopically homogenous and within uncertainty of the value for modern seawater. If this ...

Pulmonary embolism in travellers has been described (Beighton and Richards, 1968; Horsley, Smail and Thould, 1975; Symington and Stack, 1977), but only occasionally has it been associated with travel by air. Increase in air travel, longer flights and the carriage of passengers who are unfit may cause this event, now rare but probably underdiagnosed, to occur more often. Cardiovascular morbidity...

The modified sigmoidal bacteria growth functions (the Gompertz, logistic, and Richards) were used to evaluate the methane production process kinetics of agricultural wastes. mesophilic anaerobic co-digestion experiments conducted with various wastes as feedstocks, including cow manure, corn straw, grape leaves, vines, wine residue, strawberry tomato leaves. results showed that manure other incr...

The lack of dietary diversity is a severe problem experienced by most poor households globally. In particular; women of reproductive age (WRA) are at high risk of inadequate intake of micronutrients resulting from diets dominated by starchy staples. The present study considered the diets, dietary diversity, and food security of women aged 15-49 years along the rural-urban continuum in three Sou...

Six classical growth functions (monomolecular, Schumacher, Gompertz, logistic, Richards, and Morgan) were fitted to individual and average (by parity) cumulative milk production curves of Canadian Holstein dairy cows. The data analyzed consisted of approximately 91,000 daily milk yield records corresponding to 122 first, 99 second, and 92 third parity individual lactation curves. The functions ...
