In this paper, we propose a newly developed suspension system called “Pentad Grade Assist Suspension (PEGASUS)”. PEGASUS has high mobility as well as rocker-bogie suspension, with very simple mechanism called only-one-joint architecture. PEGASUS is able to successfully climb up on the stepalike terrain with low energy consumption by scale model test. The prototype of micro planetary rover Micro...

A novel kind of spherical cellulose nanocrystal (SCNC) suspension was prepared by hydrolysis of microcrystalline cellulose with a mixture of sulfuric acid and hydrochloric acid under ultrasonic treatment. The mechanism of SCNC formation and the liquid crystalline properties of their suspensions were investigated. A suspension of spherical particles was usually inclined to form crystallization c...

Jointly owned by the University of Oklahoma (OU) and Oklahoma State University (OSU), the Oklahoma Mesonet has provided valuable meteorological measurements since the early 1990’s. With over 110 stations located across the state of Oklahoma, the Mesonet is a state-ofthe-art network that measures several hydrological, agricultural, and meteorological variables (Brock et al. 1995; McPherson et al...

Two Common Gene Variants on Chromosome 9 and Risk of Atherothrombosis To the Editor: McPherson et al recently reported (in the journal Science) the association of 2 single nucleotide polymorphisms (rs10757274 and rs2383206) with coronary heart disease (CHD).1 After their report, we examined the possible association of these 2 gene variants with atherothrombotic events using a prospective, neste...
