Time-Intensity Studies of Sweeteners

High-Intensity Sweeteners in Alternative Tobacco Products

INTRODUCTION Sweeteners in tobacco products may influence use initiation and reinforcement, with special appeal to adolescents. Recent analytical studies of smokeless tobacco products (snuff, snus, dissolvables) detected flavorants identical to those added to confectionary products such as hard candy and chewing gum. However, these studies did not determine the levels of sweeteners. The objecti...

postnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...

A common genetic influence on human intensity ratings of sugars and high-potency sweeteners.

The perception of sweetness varies among individuals but the sources of this variation are not fully understood. Here, in a sample of 1,901 adolescent and young adults (53.8% female; 243 MZ and 452 DZ twin pairs, 511 unpaired individuals; mean age 16.2±2.8, range 12–26 years), we studied the variation in the perception of sweetness intensity of two monosaccharides and two high-potency sweetener...

Intensity studies of inelastic electron tunneling spectra

Inelastic electron tunneling spectroscopy (IETS) using metal}insulator}metal (MIM) tunnel junctions is an established technique for studying the vibrational modes of molecules adsorbed on metal surfaces. We are examining a new geometry for IETS in which the oxide layer of the MIM junction is replaced by an atomically thin gas "lm. `Cleana junctions in which the barrier is composed of pure neon ...
