Arsenic is present in the environment as a naturally occurring substance or as a result of contamination from human activity. It is found in water, air, food, and soil in organic and inorganic forms.
Latent Semantic Analysis (LSA), sometimes referred to as Latent Semantic Indexing (LSI), is an information modeling and analysis technology. It enables you to organize and examine large collections of information based on meaning (semantics), not just matching the words or items being used.
LSA starts as inflammation of the glans that can result in severe narrowing of the urethral opening, high pressure voiding and eventual inflammation of the (Littre) glands in the tissue surrounding the urethra. Potentially, extensive urethral stricture disease can occur in this manner.
