A Solid‐Phase Approach to Chiral C2‐Substituted Cyclen and DOTA‐Like Lanthanoid Ligands

open access: yesChemistry – A European Journal, EarlyView.
Chiral C2‐substituted cyclen derivatives have been designed and synthesized from chiral cyclic peptoids. Their conversion into the corresponding DOTA‐type ligands opens new avenues for the development of high‐relaxivity MRI contrast agents. ABSTRACT Magnetic resonance imaging (MRI) is a powerful diagnostic modality that relies on Gd+3‐based contrast ...

Factors Affecting Initial Roughness of Concrete Pavement

Journal of Performance of Constructed Facilities, 2007
Past studies have shown that initial pavement roughness greatly affects future pavement roughness and roughness progression rate. Initial pavement roughness is also an important input to the roughness prediction model in mechanistic-empirical design guide.

Evolution of Pavement Winter Roughness

Transportation Research Record: Journal of the Transportation Research Board, 2005
The functional service level of roads is quantified in terms of roughness. This parameter considers every road surface defect that causes passenger vehicle discomfort. Roughness is measured by a quality index, the international roughness index (IRI). Roughness gives an overall appreciation of road profile quality without, however, permitting a deeper ...
