Flexible pavements comprise about 93 percent of paved roads in the United States. Although flexible pavements are widely used for reasons such as cost, constructability and consistent performance, they are often subject to severe rutting. Rutting is the accumulation of longitudinal depressions under the wheelpaths caused by the repeated traffic loads. Rut is a major concern for the integrity of...

A new meiotic mutation, moremight (mzur) was identified by screening for new mutations that act as dominant enhancers of the dosage-sensitive Drosophila melanogaster female meiotic mutant, nod”? mwr is a recessive meiotic mutant, specifically impairing the segregation of nonexchange chromosomes. Cytological evidence suggests that the meitoic defect in mwr/mw females is in homologue recognition ...

We present a new method of image coding in structured light 3D scanning called Color-Coding. The method reduces the number of projected patterns needed to generate the code used to retrieve depths of an object being scanned to only three slides, each one containg RGB values that identify the vertical image stripes correctly. The technique converts the RGB values to the well-known Gray-Code algo...

Fertilization of sea urchin eggs initiates an increased amino acid incorporation into proteins.1' 2 This stimulation of protein synthesis has been attributed to activation of ribosomes.3 Nemer4' I and Wilt and Hultin' found that the synthetic messenger RNA polyuridylic acid stimulates homogenates from unfertilized eggs to synthesize polyphenylalanine. After fertilization, messenger RNA may comb...

Introduction: CM carbonaceous chondrites display a wide range of aqueous alteration products that occurred by low temperature water-rock reactions on their parent bodies [1,2]. Previous modeling studies have verified that these reactions occurred at low temperatures (0-50C), for they reproduced many of the observed mineral assemblages [3]. The dominant phases are tochilinite and Mg-Fe phyllosil...

Changes in water content and dry weight were determined in control cells and those induced to cold harden in response to abscisic acid (ABA) treatment (7.5 x 10-5 molar). Bromegrass (Bromus inermis Leyss cv Manchar) cells grown in suspension culture at room temperature (230C) for 7 days acclimated to -28°C (LT50) when treated with ABA, or to -50C when untreated. ABA significantly reduced cell g...

Introduction Recent advances in molecular biological techniques have enabled investigators to determine the spatial and temporal expression of genes during fracture healing. Thus far, however, a limited number of genes have been identified, and details of the healing processes have not been fully established. In the previous study, we have used a quantitative cDNA microarray technique, and comp...

Experiments comparing the photosynthetic responses of a chillingresistant species (Pisum sativum L. cv Alaska) and a chiHling-sensitive species (Cucumis sativus L. cv Ashley) have shown that cucumber photosynthesis is adversely affected by chilling temperatures in the light, while pea photosynthesis is not inhibited by chilling in the light. To further investigate the site ofthe differential re...
