Results of preliminary pollen analyses of 280 samples from selected intervals of cores from Hole 798 on the Oki Ridge in the Sea of Japan (Sections 798A-1H-1 through 798A-3H-3,798B-1H, 798B-13H1 through 798B-15H-8, and 798C-1H-1 through 798C-1H-3) indicate that (1) diagnostic pollen types of the vegetation of Japan are abundant and well-preserved in sediments deposited over the last 1.4 m.y.; (...

lon-chromatography, a relatively new technique in a nal yti cal chemistry, has already shown great promise toward solving complex trace analysis problems, in particular the speciat ion and quantitation of allion~. It is especially attractive to the fi e ld of microanalysis. The method of sample preparation, however, is (Tucial in order to realize this capac it y. Existing microanalytical method...

T bstract his study evaluated the time, occurrence of fracture, nd quality of apical cavity preparation with three ifferent ultrasonic diamond tips: Satelec, Trinity, and a ew type, CVD (chemical vapor deposition), using scaning electron microscopy (SEM) analysis. Thirty human ingle-rooted premolars were selected, submitted to picectomy, and prepared with ultrasonic tips; impresions were then o...

When hydrocortisone was made available for clinical trials in the spring of 1951, three facts seemed relevant: (1J The hormone was the principal, probably the natural, glycogenic steroid secreted by the adrenal cortex (Hechter, 1950; Hechter and others, 1951; Reich and others, 1950; Savard and others, 1952; Bush, 1951; Conn and others, 1951; Jacobsen and Pincus, 1951; Pincus, 1949; Mason, 1950)...

ingle-case research designs are a diverse and powerful set of procedures useful for demonstrating causal relations among clinical phenomena. Although such designs are flexible, efficient, and have been used to make key advances since the earliest days of psychological science, they are currently extremely underused by psychological scientists and clinicians. We review the historical and theoret...

We present a hybrid CMOS-based microfluidic system that combines magnetic actuation of microparticles with in situ optical detection using ingle photon avalanche diodes (SPADs). The decoupling of the principles used for actuation and sensing permits a high sensitivity with respect to etection and particle handling. Single magnetic microparticles are transported within a glass micro-capillary po...

n regards to the recently published paper by Hurst et al. (1), I would ike to emphasize some of the classic echocardiographic features that re useful for early diagnosis of stress cardiomyopathy (2). In the classic ase, the most important feature is apical ballooning involving all left entricular (LV) walls with a hyperdynamic base, not limited to any ingle coronary territory (Fig. 1). The diag...
