In this paper, the structure of SAW has been studied. In previous work in SAW, materials such as lithium niobium, lithium tantalite and gallium nitride were used in the structure of SAW, and thus had a low operating frequency and the highest reported operating frequency was about 4 GHz. In this paper, aluminum nitride and gallium nitride in the SAW structure are used in combination. The electro...

BACKGROUND Therapeutic drug monitoring of the anticonvulsant levetiracetam may be indicated in patients with conditions that may alter pharmacokinetic characteristics, for tailoring individual dosage regimens or to investigate patient compliance. In this study, the Bio-Rad high-performance liquid chromatography (HPLC) method (in-use method) and the ARK immunoassay method (new method) for leveti...

physician. He was educated by private tuition and at Aberdeen and Glasgow Universities, and took the degrees (with honours) M.B. and C. M. in 1863, at the age of twenty-one. In 1883 he became M.D. (Aber.), M.R.C.P. (Lond.), in 1889, and F.R.C.P. in 189-i. He was also made an LL.D. of Aberdeen. Shortl}7 after his arrival in India Harvey saw his first field service in the Bhootan War of 1865-6, f...

1839, or nearly eighty years ago, just in time to be sent to join the army in Afghanistan, of which campaign his letters give very interesting glimpses; he saw Dr. Brydon, the "Remnant of an Army" brought into Jellalabad, and went through the siege of the cantonment at Kabul in 1841. Chapter III of the little book gives an account of the work of Hare on quinine and malaria. When E. C. Hare arri...

Yi-Chih Chien and Glen E. Collier (1997) Biochemical comparison of arginine kinase allozymes in Drosophila melanogaster. Zoological Studies 36(4): 277-287. ARKs is a rare arginine kinase allozyme found in natural populations of Drosophila melanogaster. To test whether the rarity of this allozyme could be due to its biochemical impairment relative to the common allozyme, biochemical properties s...
