In this paper we relate the Fefferman–Graham ambient metric construction for conformal manifolds to the approach to conformal geometry via the canonical Cartan connection. We show that from any ambient metric that satisfies a weakening of the usual normalisation condition, one can construct the conformal standard tractor bundle and the normal standard tractor connection, which are equivalent to...

A survey of Indiana farm home was conducted in the winter of 1994-1995 to establishrealistic baselines concerning child safety practices for populations in rural Indiana for the purpose of1) adjusting interventions to target specific issues where prevention efforts are most needed and 2)evaluating the effectiveness of safety efforts targeting rural Indiana families. A questionnaire ...

To reduce greenhouse gas emissions, ports around the world are considering using electric cargo handling equipment. To assess the benefits of the strategy, this study provides a comparative life-cycle assessment between diesel and electric yard tractors in a case study of the Port of Los Angeles. Results indicate a significant reduction in life-cycle emissions as the port shifts to electric veh...

The safest and least traumatic means of removing a cemented restoration is to cut a slot and pry the crown or retainer loose, sacrificing the restoration. However, various techniques and instruments for intact removal of permanently cemented cast restorations have been described in the literature. This literature review explores conservative and semiconservative techniques that are useful for p...

The article proposes and substantiates a method for indirect determination of the energy parameters operation an agricultural tractor engine, which makes it possible to calculate establish most energy-efficient mode performing operation. proposed determining engine by measuring turbocharging pressure, with high accuracy, is highly informative has number advantages compared traditional methods i...
