Introduction Medicinal plants have been used since ancient times as medicines for the treatment of a wide range of diseases. Morinda citrifolia L (Noni) has been used in folk remedies by Polynesians for over 2000 years, and is reported to have a broad range of therapeutic effects, including effects against headache, fever, arthritis, gingivitis, respiratory disorders, infections, tuberculosis a...

BACKGROUND Environmental mycobacteria (EM) include species commonly found in various terrestrial and aquatic environments, encompassing animal and human pathogens in addition to saprophytes. Approximately 150 EM species can be separated into fast and slow growers based on sequence and copy number differences of their 16S rRNA genes. Cultivation methods are not appropriate for diversity studies;...

Together with generalized self-similarity and the fractal spectrum, local singularity analysis has been introduced as one part of the new 3S principle and technique for mineral resource assessment based on multifractal modeling, which has been demonstrated to be useful for anomaly delineation. Local singularity is used in this paper to characterize the property of multifractal distribution patt...

Petition canvassers are political recruiters. Building upon the rational prospector model, we theorize that rational recruiting strategies are dynamic (Bayesian and time-conscious), spatial (constrained by geography), and social (conditioned on relations between canvasser and prospect). Our theory predicts that canvassers will exhibit homophily in their canvassing preferences and will alternate...

Track circuit coding can be realized by Train Control Center in Highspeed Railway to keep the train running safe. This paper looks into the track circuit coding method using expert system, in which the reasoning process of track circuit coding was realized using software simulation with the data of Beijing-Shanghai High Speed Railway. Combined with test cases, the joint debugging is realized an...

Purcell Mountains as a roadless tract of recreational wilderness area. It is located in the rugged mountain range between Kootenay Lake and the Columbia Valley, centred approximately 30 kilometres north of Kimberly (Figure 1-3-1) and is adjoined on the south by St. Mary's Alpine Provincial Park. Resource development, including mineral exploration and mining, was prohibited and any existing clai...

Broadband frequency-domain electromagnetic sensors can be used not only to detect but also to characterize and identify a particular mineral deposit based on its spectral response. The concept is similar to identifying a particular landmine based on its unique spectral response, which is known as Electromagnetic Induction Spectroscopy (EMIS). Recent advances in single-coil, broadband sensors ha...
