Measuring ease of access to transit services is important in evaluating existing services, predicting travel demands, allocating transportation investments, and making decisions on land development. A composite index to assessing accessibility of public transit is described. It involves use of readily-available methods and represents a more holistic measure of transit accessibility, integrating...

The inability of Neisseria gonorrhoeae to survive prolonged transit times and hostile ambient temperatures has made its detection at referral laboratories by cultural methods untenable. In this situation, reliance upon antigen detection systems is attractive but when these tests are performed on vaginal specimens from children, false positive results are a significant concern. Some of the diffi...

BACKGROUND/AIMS To investigate whether transit time could influence H2 consuming flora and certain indices of colonic bacterial fermentation. METHODS Eight healthy volunteers (four methane excretors and four non-methane excretors) were studied for three, three week periods during which they received a controlled diet alone (control period), and then the same diet with cisapride or loperamide....

The preservation and promotion of neighbourhood identity is important in contemporary cities. Los Angeles, long known for its lack of both effective mass transit and, separately, local identity and cohesion among its neighbourhoods, is currently working to address each of these issues, yet little attention has been paid to the possibility that the two can be directly related. This paper investi...

We have detected excess absorption in the emission cores of Ca II H&K during transits of HD 189733b for the first time. Using observations of three transits, we investigate the origin of the absorption, which is also seen in Hα and the Na I D lines. Applying differential spectrophotometry methods to the Ca II H and Ca II K lines combined, using respective passband widths of λ= 0.4 and 0.6 Å yie...
