We predicted the effects of sulfate (SO(4)) deposition on wilderness areas designated as Class I air quality areas in western North Carolina using a nutrient cycling model (NuCM). We used three S deposition simulations: current, 50% decrease, and 100% increase. We measured vegetation, forest floor, and root biomass and collected soil, soil solution, and stream water samples for chemical analyse...

INTRODUCTION Because foods fortified with calcium are increasingly available, the calcium content of calcium-fortified foods may not be adequately captured in traditional assessments of dietary intake, such as dietary records analyzed with commercially available software. The primary objective of our study was to design and test a calcium-focused food frequency questionnaire (CFFFQ) including f...

OBJECTIVE To determine if dietary calcium was negatively related to children's body fat (BF), if BF indexes and calcium intakes changed over time, and to identify variables related to BF and calcium intake. DESIGN Percent BF and kg BF were assessed by dual energy x-ray absorptiometry (DEXA) in 8-year-old children. In a prospective design, height, weight, dietary intakes, and related variables...

Introduction: The aim of this study was to investigate the effects of the ethanolic extract of Nigella sativa L (NS) seeds on kidney calculi in rats. Materials and Methods: Thirty-two Wistar rats were randomly divided into 4 groups: group A received tap drinking water for 30 days (intact control). Groups B, C, and D received 1% ethylen glycol for induction of calcium oxalate calculus formation....

Numerous previously unknown carbon aluminum hydride cluster anions were generated in the gas phase, identified by time-of-flight mass spectrometry and characterized by anion photoelectron spectroscopy, revealing their electronic structure. Density functional theory calculations on the CAl5-9H- and CAl5-7H2- found that several of them possess unusually high carbon atom coordination numbers. Thes...

Lapsamita maddisoni gen. et sp. nov. is described from Bahia, Brazil. The presence of palpal claws in females, long ventral spines on front tibiae and metatarsi and long retrolateral tibial apophyses in male palps suggested that the species was closely related to or even nested within Soesiladeepakius Makhan, 2007. To evaluate its phylogenetic position, a cladistic analysis was carried out usin...

Temperature programmed desorption has been used to study the desorption kinetics and desorption energies of perfluorodiethylether, (CF3CF2)2O, and 2,2,2-trifluoroethanol, CF3CH2OH, adsorbed on fresh and oxidized hydrogenated amorphous carbon (a-CHx) films. (CF3CF2)2O and CF3CH2OH serve as models for the ether backbone and hydroxyl end-groups of Fomblin Zdol, the lubricant most commonly used to ...

Submitted for the MAR16 Meeting of The American Physical Society Collective Calcium Dynamics in Networks of Communicating Cells TOMMY BYRD, Purdue University, GARRETT POTTER, BO SUN, Oregon State University, ANDREW MUGLER, Purdue University — Cells can sense and encode information about their environment with remarkable precision. These properties have been studied extensively for single cells,...

1Princess Iman Research and Laboratory Sciences Centre, King Hussein Medical Centre, Amman, Jordan. Received: 27/05/02; accepted: 21/04/03 ABSTRACT Haematoxylin and eosin (H&E) is the most popular routine stain used in pathology laboratories for highlighting cellular structures. To study the effect of tap water ‘softening’ (i.e. calcium extraction) on H&E stains, 5 sets of slides from 30 differ...
