The primary purpose of longitudinal safety barriers, such as cable barriers, is to contain and/or redirect errant vehicles that depart the roadway, hence keeping them from entering opposing travel lanes or encountering terrain features and roadside objects that may cause severe impacts. In this paper, vehicle dynamics analysis is used to study the effect of(More)
A detailed multi-purpose finite element model of a 1994 Chevrolet C-1500 pick-up truck was developed at the FHWA/NHTSA National Crash Analysis Center. The model is the first of its kind developed specifically to address vehicle safety issues, including front and side performance, as well as road side hardware design. The former application typically(More)

A total alkaloid and two purified alkaloid extracts of Alangium vitiense were found to be oncostatic for L1210 leukemia; the total alkaloid exerted a noticeable activity, and the purified extracts exerted a borderline activity. These two purified extracts are noticeably oncostatic for two other lymphoid neoplasias in mice, P388 leukemia and Gardner(More)
Ten monomeric indole alkaloids have been identified from the roots of KOPSIA OFFICINALIS. Four of them are known: (-)-kopsinine 1, (+)-5,22-dioxokopsane 2, (-)-tetrahydroalstonine 4, and (-)-quebrachamine 3; and six are new: (-)-isoeburnamine 5 (enantiomer of the known alkaloid (+)-isoeburnamine), (-)-N-methoxycarbonyl-12-methoxykopsinaline 7,(More)

This research investigated (1) what are the key attributes of the between-rail, frontal crash, (2) what are the types of object contacted, and (3) what is the type of resulting trauma. The method was to study with both weighted and in-depth case reviews of NASS-CDS crash data with direct damage between the longitudinal rails in frontal crashes. Individual(More)
This paper describes a finite element computer simulation of a New Car Assessment Program (NCAP) full scale crash test. The full scale test selected for this study is a 30mph frontal impact of a 1993 Ford Taurus vehicle into a rigid flat wall. Finite element models of a Ford Taurus vehicle, a Hybrid III dummy, and a driver side airbag were combined to(More)
