We present a complete library of synthetic spectra based on Kurucz’s codes that covers the 2500–10 500 Å wavelength range at resolving powers RP=20 000, 11 500 (≡ GAIA), 8500 (≡ RAVE), 2000 (≡ SLOAN) and uniform dispersions of 1 and 10 Å/pix. The library maps the whole HR diagram, exploring 51 288 combinations of atmospheric parameters spanning the ranges: 3500 ≤ Teff ≤ 47 500 K, 0.0≤ log g ≤ 5...

Measurement of phenylalanine in plasma is required for the diagnosis and subsequent dietary management of phenylketonuria (PKU). We have developed an isocratic high-performance liquid-chromatographic (HPLC) method, with ultraviolet detection. For this measurement 10 microL of plasma is needed, and the complete analysis can be done in less than 15 min. Interbatch coefficients of variation for hu...

BACKGROUND Some fluoridated toothpastes, available commercially, are described to have a protective effect against dental erosion. OBJECTIVES To evaluate the influence of the selected marketed toothpastes on the human enamel exposed to acid beverages. MATERIAL AND METHODS Enamel specimens from extracted human teeth were prepared (n = 40). Specimens were randomly divided into 10 experimental...

Analysis of DDT isomers and breakdown products, DDD and DDE, in over 3500 bivalve samples collected from more than 300 locations along the continental United States indicates that concentrations are decreasing. Overall average concentrations for the East (45.8±24.6 ng/gdw), Gulf (42.4±21.1 ng/gdw), and West (90.9±43.3ng/gdw) coasts are declining with an environmental half-life between 10 and 14...

The relative efficiency of the Waring blender, the Stomacher 400, and the Stomacher 3500 for preparing food samples for microbiological analysis was studied. Comparative aerobic plate count (APC) values were determined on 671 samples, representing 30 categories of foods. Of the 26 categories of nonfatty foods, the blender gave significantly higher geometric mean APC values than those given by t...

Familial defective apolipoprotein (apo) B-100 (FDB) is caused by R3500Q mutation of the apo B gene resulting in decreased binding of LDL to the LDL receptor. Two other apo B mutations, R3500W and R3531C, affecting binding are known to date. We screened the apo B gene segment around codon 3500 by heteroduplex analysis and single strand conformation polymorphism (SSCP) analysis in a total of 373 ...

Microbial biomass phosphorus (MBP) is one of the most active forms of phosphorus (P) in soils. MBP plays an important role in the biogeochemical P cycle. To explore MBP distribution and its relationship with other factors, the MBP and rhizosphere soil P concentrations and fractions in six vegetation zones on the eastern slope of Gongga Mountain in SW China were investigated. The MBP distributio...

This research aimed at identifying the role of emotional intelligence (EI) -based management in improving faculty effectiveness. Research methodology was descriptive-survey of exploratory type. Statistical population were the faculty members in the Islamic Azad University branches across Tehran (N = 3500). The subjects of the study (sample) consisted of 351 faculty members selected through stra...
