abstract:   background: the most important and complex phenomenon of respiratory function of the nose is related to different nasal anatomy. the differences in facial anatomic structure between different races may also be reflected in nasal resistance and airflow. caucasians has different facial anatomic structure which is the reflection of intranasal resistance or consequence of airflow. the a...

  Exploration into the concept of "medical expert" dates back to more than 50 years ago, yet yielding three leading theories in the area of clinical reasoning, namely, knowledge structure, hypothetic-deductive, and dual process. Each theory defines “medical expert” in a dissimilar way. Therefore, the methods of assessment through which the experts are identified have been changed during the tim...

background: mushroom tyrosinase a potent candidate in clinical studies known as polyphenol oxidase, is a metaloenzyme from the oxidase superfamily widely distributed from lower to higher life forms. it plays a crucial role in sclerotization of exoskeleton in insects, also responsible for skin pigmentation in mammalians. objective: in this study, after reconstitution of mt by some metal ions, th...

BACKGROUND Practitioners of manual medicine/manual therapy (MM/MT) who utilize techniques thought to have some impact upon and move the solid structures of the human head have been criticized for lack of evidence of cranial bone motion. The present study utilized magnetic resonance imagery (MRI) technology to address the question of whether or not inherent (non-operator initiated) calvarial str...

In common buildings the soil-structure-interaction (SSI) is governed by the elastic behaviour of the building. The best conditions to see the soil effect predominate would be a dynamic rigid body movement of a massive building. For this reason measurements were carried out on an old anti-aircraft tower from World War II on typical Viennese soil conditions. The dynamic properties of the soil cou...

This article is an introduction to the special issue of the journal Proteins, dedicated to the sixth CASP experiment to assess the state of the art in protein structure prediction. The article describes the conduct of the experiment and the categories of prediction included, and outlines the evaluation and assessment procedures. A brief summary of progress over the decade of CASP experiments is...

The factor structure of the Negative Symptom Assessment (NSA), a standardized negative symptoms rating scale, was systematically evaluated in a group of 223 inpatients with schizophrenia. Confirmatory factor analyses found that a six-factor model best described the NSA. More specifically, the domains of Communication, Emotion/Affect, Social Involvement, Motivation, Gross Cognition, and Retardat...

THE FEBRUARY 15TH, 2010, issue of the American Journal of Respiratory and Critical Care Medicine contains an official research policy statement on quantitative assessment of lung structure (1). This document is the product of a Joint American Thoracic Society (ATS) and European Respiratory Society (ERS) task force created in response to a widespread recognition that many investigators were publ...

1An abbreviated version of this paper was presented at the Biswell Symposium: Fire Issues and Solutions in Urban Interface and Wildland Ecosystems, February 15-17,1994, Walnut Creek, California. 2Research Physical Scientist, Southern Research Station, USDA Forest Service, Southern Forest Fire Laboratory, Route 1, Box 182A, Dry Branch, GA 31020. Abstract: Major wildland/urban interface fire loss...

Lay perceptions of risk appear rooted more in heuristics than in reason. A major concern of the risk regulation literature is that such "error-strewn" perceptions may be replicated in policy, as governments respond to the (mis)fears of the citizenry. This has led many to advocate a relatively technocratic approach to regulating risk, characterized by high reliance on formal risk and cost-benefi...
