This paper presents an ultra low power clock source using a 1μW temperature compensated on-chip digitally controlled oscillator (OscCMP) and a 100nW uncompensated oscillator (OscUCMP) with respective temperature stabilities of 5ppm/C and 1.67%/C. A fast locking circuit re-locks OscUCMP to OscCMP often enough to achieve a high effective temperature stability. Measurements of a 130nm CMOS chip sh...

An alginate-degrading bacterium, identified as Ochrobactrum sp. on the basis of 16S rDNA gene sequencing, was isolated from brown algal samples collected from the waters in close vicinity to the Dongtou Isles in the East China Sea. The strain, designated WZUH09-1, is a short rod, gram-negative, obligatory aerobic, grows under the following conditions: 5-40C, pH 3-9, and 0-2 times of the seawate...

An investigation was performed on the possibilities for an alteration of the total solidification temperature when preserving concentrated salt media (BME, MEM, 199, HAM), used for the maintenance of animal viruses and cell cultures. It had been established that by the use of dextran 40000, this temperature could be increased with about 20C. A protection in 3.6 % concentration was recommended a...

The purpose of this research was to produce cocoa butter equivalent from the blend of mango seed almond fat (MAF) from “Keaw” variety mango kernels and palm oil mid-fraction (POMF). Seven MAF-POMF blends with different proportions (100/0, 90/10, 80/20, 70/30, 60/40, 50/50 and 0/100 (%wt) of MAF to POMF) including cocoa butter were characterized using various techniques. Fatty acid composition w...

According to J.A.N. Lee in 1996, computer scientists “are reaching the stage of development where each new generation of participants is unaware both of their overall technological ancestry and the history of the development of their speciality, and have no past to build upon” [1, p.54]. A technically and historically accurate account, as attempted here, can help us, computer scientists, grasp ...

A new general reaction for the preparation of isomerically pure hydroxyalkylated C(60) monoadducts, via the free radical photochemical addition of alcohols to [60]fullerene, is described.
