Analysis of proposed criteria for human response to vibration

The development of criteria for human vibration response is reviewed, including the evolution of the ISO standard 2631. The document is analyzed to show why its application to vehicle ride evaluation is strongly opposed. Alternative vertical horizontal limits for comfort are recommended in the ground vehicle ride frequency range above 1 Hz. These values are derived by correlating the absorbed power findings of Pradko and Lee with other established criteria. Special emphasis is placed on working limits in the frequency range of 1 to 10 Hz since this is the most significant area in ground vehicle ride evaluation

Venture Capital Fund Performance and the IPO Market

In this paper, the investment performance of a large database of venture funds is considered over a 28 year period. The results suggest that a portfolio of venture capital partnerships can provide an average return that is superior to the public equity market, although the individual fund returns are highly positively skewed. Absent these outliers, the level of fund performance is more in line with public equity market returns. This paper also establishes a link between public equity market conditions and venture capital returns. Finally, some preliminary evidence is provided of venture fund performance during and immediately following the dot.com bubble

Perceptions of secondary physical education teachers towards the fitnessgram

This project was intended to examine the perceptions of physcial educators toward the Fitnessgram that has five factors to gauge a student\u27s abilities and the norms for each age group. The test is given to 5th, 7th and 9th grade students. The Fitnessgram as it has been enacted has become a more consistent and reliable tool for physical educators

Development of Cd8α/α and Cd8α/β T Cells in Major Histocompatibility Complex Class I–Deficient Mice

Peripheral CD8+ T cells mainly use CD8α/β, and their development is mainly dependent on the major histocompatibility complex (MHC) class I proteins Kb and Db in H-2b mice. In this report, we have shown that the development of CD8α/β TCR-α/β cells in lymphoid organs as well as in intestinal intraepithelial lymphocytes (iIELs) is dependent on the MHC class I Kb and Db proteins. In contrast, TCR-α/β CD8α/α cells are found mainly in iIELs, and their numbers are unaffected in KbDb double knockout mice. Most of the TCR-γ/δ cells in the iIELs also bear CD8α/α, and they are also unaffected in KbDb −/− mice. In β2-microglobulin (β2m)-deficient mice, all of the TCR-α/β CD8α/α and CD8α/β T cells disappear, but TCR-γ/δ cells are unaffected by the absence of β2m
