We perform total energy calculations on a manganese atom encapsulated inside a C(60) cage using density functional theory with the generalized gradient approximation through three optimization schemes and along four paths inside the cage. We find that when Mn is located in the central region, its electronic and magnetic properties are not exactly the same as those of a free Mn atom due to weak ...

OBJECTIVE To determine the internal consistency and 1-week test-retest reliability of the Simple Screening Instrument for Alcohol and Other Drug Abuse (SSI-AOD), the CAGE-AA (CAGE questions adapted for adolescents), and 4 modified items from the Drug and Alcohol Problem QuickScreen (DAP-4) among adolescents. METHODS Fifteen- to 18-year-old medical patients (n = 173) completed screening tests ...

Tsetse flies (Glossina sp.) infest over 11 million km2 of Africa, and are vectors of Trypanosomosis (or Trypanosomiasis) in both man and domestic livestock. For example, it is estimated that tsetse occur over 7 percent of Zimbabwe and 60 percent of Tanzania and Trypanosomosis has an important negative impact on livestock production in these areas. An odour dispenser is an integral component of ...

BACKGROUND Collection of the black fly vectors of onchocerciasis worldwide relies upon human landing collections. Recent studies have suggested that the Esperanza Window Trap baited with a human scent lure and CO2 had the potential to replace human hosts for the collection of Simulium ochraceum sensu lato in Southern Chiapas focus, Mexico. The feasibility of utilizing these traps in a community...

The synthesis of novel acetal thia-cage compounds has been accomplished by the direct substitution for the oxygen atom by the sulfur atom in the reaction of the acetal groups of oxa-cages with Lawesson reagent (LR). Reaction of the tetraoxa-cage compound 2 with LR in dichloromethane at 25 degrees C sequentially gave the monothia-, dithia-, trithia-, and tetrathia-cage compounds 3, 6, 7, and 9. ...

The temporal incidence of cabbage maggot, Delia radicum L. was investigated using three exclusion cage experiments, one each during spring, summer and fall, in broccoli fields as well as two surveys, one each in three broccoli fields, and sixteen turnip plantings in central coast of California. In the cage experiments, sets of broccoli plants were exposed to natural populations of D. radicum fl...

OBJECTIVES To describe potentially hazardous alcohol use among elderly patients in the primary care setting and to assess the widely used CAGE questionnaire (cut down, annoyed by criticism, guilty about drinking, eye-opener drinks) as a tool for detecting self-reported heavy and binge drinking among these patients. DESIGN Cross-sectional study. SETTING The offices of 88 primary care physici...

A three-step, quasi-double-bind approach was used as a proof-of-concept study to screen twenty compounds for their ability to reduce oviposition of gravid female navel orangeworm(NOW), Ameylois transitella (Lepidoptera: Pyralidae). First, the panel of compounds, whose identity was unknown to the experimenters, was tested by electroantennogram (EAG) using antennae of two-day old gravid females a...
