TO THE EDITOR: The review by Matute-Bello et al. (15) has misleading and potentially dangerous statements concerning the role of hyperoxia in human acute lung injury (ALI). Table 4 states “in normal human lungs, 100% oxygen has not induced lung injury . . . ” The text states that most mammalian species develop respiratory distress and die with exposure to 100% oxygen, but the “same findings hav...

We investigated the deep-sea sedimentary sequence of core MD012422 corresponding to last 350 ka (since marine isotopic stage, MIS 10) from off Shikoku Island, NW Pacific Ocean, and refined its tephrostratigraphy. detected many tephras cryptotephras correlated them with terrestrial on basis major- trace-element compositions their glass shards. Then we cross-checked our results against reported t...

Building blocks with amine functionality are crucial in the chemical industry. Biocatalytic syntheses and chemicals derived from renewable resources increasingly desired to achieve sustainable production of these amines. As a result, materials such as furfurals, especially furfurylamines like 5-(hydroxymethyl)furfurylamine (HMFA) 2,5-di(aminomethyl)furan (DAF), gaining increasing attention. In ...

This paper sets out to clear up a misconception prominent in the storage community today, that SCSI disc drives and IDE (ATA) disc drives are the same technology internally, and differ only in their external interface and in their suggested retail price. The two classes of drives represent two different product lines aimed at two different markets. In fact, both classes contain a range of produ...

Community participation was identified as one of the key components of Primary Health Care as articulated in the Alma Ata declaration of 1978 and is enjoying a renewal of interest in both low and high income countries. There remains, however, an on-going challenge in how to assess its role in achieving health improvements. This is largely due to the multiplicity of definitions of community part...
