Electromagnetic Linear Vibration Energy Harvester Using Sliding Permanent Magnet Array and Ferrofluid as a Lubricant.

We present an electromagnetic linear vibration energy harvester with an array of rectangular permanent magnets as a springless proof mass. Instead of supporting the magnet assembly with spring element, ferrofluid has been used as a lubricating material. When external vibration is applied laterally to the harvester, magnet assembly slides back and forth on the channel with reduced friction and wear due to ferrofluid, which significantly improves the long-term reliability of the device.

Hepatic expression of cytochrome P450 in Zucker diabetic fatty rats.

In this study, the hepatic expression of cytochrome P450 (CYP) enzymes, including CYP1A1/2, 2B1, 2C11, 2E1, 3A1/2, and 4A, was investigated in 5-week-old (insulinresistant state) and 11-week-old (diabetic) Zucker diabetic fatty (ZDF) rats. Serum glucose and glycated hemoglobin levels were increased in 11-week-old ZDF rats, but not in 5-weekold ZDF rats. Hyperinsulinemia was observed in both age groups.

Gramella gaetbulicola sp. nov., a member of the family Flavobacteriaceae isolated from foreshore soil.

A Gram-reaction-negative, yellow-pigmented, gliding, rod-shaped, aerobic bacterium (RA5-111(T)) was isolated from foreshore soil. The taxonomic status of the novel isolate was determined using a polyphasic approach. On the basis of 16S rRNA gene sequence similarities, strain RA5-111(T) could be assigned to the genus Gramella, with sequence similarities of 97.

Myroides marinus sp. nov., a member of the family Flavobacteriaceae, isolated from seawater.

A Gram-negative, aerobic, non-motile, yellow-pigmented, rod-shaped bacterium (strain JS-08(T)) isolated from seawater was subjected to a polyphasic taxonomic study. 16S rRNA gene sequence analysis indicated that strain JS-08(T) belongs to the genus Myroides, a member of the phylum Bacteroidetes. Its closest phylogenetic relative was Myroides odoratimimus JCM 7460(T), with which it shared 97.
