Background: There is extensive variety of chemical compounds with antiulcer activity, which are isolated from medicinal plants. Matricaria chamomilla or Matricaria recutita or German chamomile, also spelled chamomile (MC), is one of the most widely used medicinal plants. In the present study, the extract of MC flowers was evaluated for antiulcerogenic activity and acute toxicity profile. Method...

Peter Facione's generally well thoughtout set of suggestions for messing up a critical thinking test l overlooked one significant option for the construction of defective multiple-choice (hereinafter MC) tests: require the impossible. 2 Perhaps Facione was being intentionally devious, leaving this option to be discovered by the intrepid reader, but it appears that one of the MC items he uses to...

With the advancement of technology, social media has become a major source digital news due to its global exposure. This led an increase in spreading fake and misinformation online. Humans cannot differentiate from real because they can be easily influenced. A lot research work been conducted for detecting using Artificial Intelligence Machine Learning. large number deep learning models their a...

The purpose of this study is to investigate the validity of using multiple-choice (MC) items as a complement to constructed-response (CR) items when making decisions about student performance on reasoning tasks. CR items from a national test in physics have been reformulated into MC items and students’ reasoning skills have been analyzed in two substudies. In the first study, 12 students answer...

Seven strains of Mycoplasma hominis from human genital tracts were selected to produce antisera. The complement-dependent mycoplasmacidal (MC) activity and two complement-independent activities, metabolic inhibition (MI) and agglutination during growth (GA), of these sera were compared. The GA and MI tests were equivalent in titer and generally not affected by concentration of antigen; they rev...

This study investigates how Mandarin Chinese (MC) speakers learn English pitch accents under the influence of L1 prosody system. Based on Speech Learning Model (SLM), it is hypothesized that MC speakers will produce H* better than L* since MC speakers tend to associate stressed syllables with higher pitch. Another hypothesis is that MC speakers will produce pitch accents better in the sentence-...

One of the key challenges in human action recognition from video sequences is how to model an action sufficiently. Therefore, in this paper we propose a novel motion-based representation called Motion Context (MC), which is insensitive to the scale and direction of an action, by employing image representation techniques. A MC captures the distribution of the motion words (MWs) over relative loc...
