(a) Hard sudoku puzzles are usually designed for defying our logical reasonings, so we can counter with the Principle of Least Choice (PLC) by selecting the least likely one when facing the multiple choices of our next move. The harder the puzzle, the more often PLC is recommended to be used. (b) We shall give only three examples. (PLC will be…[Read more]

Patient-centered care evolves around proper coordination between healthcare providers in consultation with patient needs. Oftentimes, children play a passive role in their health care because of the controversy around age and lack of consensual abilities. The impact of engaging children early on to empower decision-making skills has been proven to…[Read more]

It is known that each natural number greater than 1 can be expressed as a unique product of prime numbers, namely the prime factorization. For example, 84=2×2×3×7. By summing up all prime factors of 84, we obtain 2+2+3+7=14. Since 14=2×7, we further sum up all prime factors of 14 to obtain 2+7=9. Since 9=3×3 and 3+3=6, we can continue the same…[Read more]

A spectrophotometric procedure has been developed for determination of hydrocarbons, vegetable oils, animal fats, waxes, soaps, greases and related oily organic matter in aqueous phase. The water sample is acidified to a low pH (less than or equal to 2) and extracted with trichloroethane (methyl chloroform). Under controlled conditions, the oil…[Read more]

A spectrophotometric procedure has been developed for determination of oil and grease in aqueous phase. The water sample is acidified to a low pH (less than or equal to 2) and extracted with 1,1,2-trichloro-l,2,2-trifluoroethane (Freon 113, or CFC 113). Under controlled conditions, the oil and grease are extractable into a selected organic…[Read more]
