The scattering far zone for light transmitted through a sphere following p - 1 internal reflections by a family of near-grazing incident rays is subdivided into a lit region and a shadow region. The sharpness of the ray theory transition between the lit and the shadow regions is smoothed in wave theory by radiation shed by electromagnetic surface waves. It is shown that when higher-order terms ...

Acute exposure of sensitized mice to antigen elicits allergic airway disease (AAD) characterized by Th2 cytokine-dependent pulmonary eosinophilia, methacholine hyperresponsiveness and antigen-specific IgE elevation. However, chronic exposure induces a local inhalational tolerance (LIT), with resolution of the airway responses but persistent systemic IgE production. To further determine if syste...

Materials and methods: Ninety pigs (9.42 ± 0.05 kg) were used in a study with five dietary treatments: an uncontaminated control diet with no additives and four similar diets that were contaminated with 500 ng per g aflatoxin B1 (AB1) and supplemented with no additive, with 0.5% HSCAS, with an antioxidant preparation providing 125 mg per kg of ethoxyquin and 10 mg per kg of TBHQ, or with both H...

Hierarchical zeolites have been established as a superior type of aluminosilicate catalysts compared to their conventional (purely microporous) counterparts. An impressive array of bottom-up and top-down approaches has been developed during the last decade to design and subsequently exploit these exciting materials catalytically. However, the sustainability of the developed synthetic methods ha...

AIM Previously, glutamine-enriched enteral nutrition in very low birth weight infants (VLBW) decreased the incidence of atopic dermatitis at age 1 year. The aim of this study was to determine whether this effect is related to changes in intestinal bacterial species that are associated with allergy, such as bifidobacteria, clostridium histolyticum, clostridium lituseburense (Chis/lit group) and ...

We present a newly developed macromolecular ion accelerator mass spectrometer that combines a dual-ion-trap device and a macromolecular ion accelerator (MIA) to achieve the capability of analyzing samples with a mixture of large biomolecules. MIA greatly increases detection efficiency. The dual ion trap includes a quadrupole ion trap (QIT) and a linear ion trap (LIT) in tandem. The dual ion tra...

Background. Depression is a serious mental health disease. Globally, it is estimated that almost 350 million people suffer from depression. It is important to assess depression literacy including knowledge and beliefs about mental disorders among adolescents. Objective. This study was conducted to validate the Arabic version of the Depression Literacy Questionnaire (D-Lit) among adolescents. Me...

Pressure on doctors to keep up with technology can be a pain, but it’s nothing new. For John Macintyre, it was not just a pleasure but an all consuming passion. Macintyre had an astonishingly inventive mind, making some of the earliest sound recordings of the great singers and actors of the late Victorian era. He had humble origins, born the son of a tailor in Glasgow’s High Street in 1857. He ...

Acknowledgements I feel very fortunate to have worked in two research laboratories as an undergraduate in the Cognitive Science Program. Through the kindness and guidance of Psychology Professor Peter Brunjes and Computer Science Professor David Luebke I've matured a great deal as a researcher in the last two years. I am very honored to consider these men my friends as well as my advisors. I wo...
