Problem: Chemical engineering is a branch of engineering that applies physical sciences (physics and chemistry), life sciences (microbiology and biochemistry), together with applied mathematics and economics to produce, transform, transport, and properly use chemicals, materials and energy. A chemical engineer designs large-scale processes that convert chemicals, raw materials, living cells, microorganisms and energy into useful forms and products.

Chemical engineers are involved in many aspects of plant design and operation, including safety and hazard assessments, process design and analysis, control engineering, chemical reaction engineering, construction specification and operating instructions. A 1996 "British Journal for the History of Science" article cites James F. Donnelly for mentioning an 1839 reference to chemical engineering in relation to the production of sulfuric acid. In the same paper however, George E. Davis, an English consultant, was credited for having coined the term. Davis also tried to found a "Society of Chemical Engineering", but instead it was named the Society of Chemical Industry (1881), with Davis as its first Secretary. The "History of Science in United States: An Encyclopedia" puts the use of the term around 1890. "Chemical engineering", describing the use of mechanical equipment in the chemical industry, became common vocabulary in England after 1850. By 1910, the profession, "chemical engineer," was already in common use in Britain and the United States.

Problem: Chapter XXX

The Man Who Dusted His Boots With His Handkerchief

When Florence Burton had written three letters to Harry without receiving a word in reply to either of them, she began to be seriously unhappy. The last of these letters, received by him after the scene described in the last chapter, he had been afraid to read. It still remained unopened in his pocket. But Florence, though she was unhappy, was not even yet jealous. Her fears did not lie in that direction, nor had she naturally any tendency to such uneasiness. He was ill, she thought; or if not ill in health, then ill at ease. Some trouble afflicted him of which he could not bring himself to tell her the facts, and as she thought of this she remembered her own stubbornness on the subject of their marriage, and blamed herself in that she was not now with him, to comfort him. If such comfort would avail him anything now, she would be stubborn no longer. When the third letter brought no reply she wrote to her sister-in-law, Mrs. Burton, confessing her uneasiness, and begging for comfort. Surely Cecilia could not but see him occasionally--or at any rate have the power of seeing him. Or Theodore might do so--as, of course, he would be at the office. If anything ailed him would Cecilia tell her all the truth? But Cecilia, when she began to fear that something did ail him, did not find it very easy to tell Florence all the truth.

Problem: ATLANTA, Georgia (CNN) -- Tyler Perry has, for the first time, revealed graphic details about the sexual, physical and emotional abuse he says he suffered as a child.

"I'm tired of holding this in," Tyler Perry wrote on his Web site, "... so I've decided to give some away."

Perry recounts in a message posted on his Web site and in an e-mail to fans that a prescreening of the film "Precious," due out later this year, dislodged "some raw emotions and brought me to some things and places in my life that I needed to deal with but had long forgotten. It brought back memories so strong that I can smell and taste them."

Perry is an executive producer of the movie, which tells the tale of Claireece "Precious" Jones, an illiterate, obese 16-year-old girl from Harlem who is emotionally and physically abused.

The 40-year-old producer says he can identify with the character, and he recalls a number of incidents from his childhood.

Emmitt Perry Sr., a construction worker, uttered profane insults at him and relentlessly beat and belittled him, Perry says. The random, violent beatings were commonplace until Perry was 19, he said.

"You ... jackass! You got book sense but you ain't got no ... common sense," he quotes his father as saying.

"I heard this every day of my childhood," says Perry.

Attempts to reach Emmitt Perry Sr. for comment were unsuccessful.

Tyler Perry was born Emmitt Perry Jr. but changed his name to distance himself from his father.
