QUES: With advances in medicinal chemistry, most modern antibacterials are semisynthetic modifications of various natural compounds. These include, for example, the beta-lactam antibiotics, which include the penicillins (produced by fungi in the genus Penicillium), the cephalosporins, and the carbapenems. Compounds that are still isolated from living organisms are the aminoglycosides, whereas other antibacterials—for example, the sulfonamides, the quinolones, and the oxazolidinones—are produced solely by chemical synthesis. Many antibacterial compounds are relatively small molecules with a molecular weight of less than 2000 atomic mass units.[citation needed]
What is the molecular weight loss of antibacterial compounds?

ANS: 2000 atomic mass units

QUES: After editing a book on John Stuart Mill's letters he planned to publish two books on the liberal order, The Constitution of Liberty and "The Creative Powers of a Free Civilization" (eventually the title for the second chapter of The Constitution of Liberty). He completed The Constitution of Liberty in May 1959, with publication in February 1960. Hayek was concerned "with that condition of men in which coercion of some by others is reduced as much as is possible in society". Hayek was disappointed that the book did not receive the same enthusiastic general reception as The Road to Serfdom had sixteen years before.
What was the title of the his 1960 book's second chapter?

ANS: The Creative Powers of a Free Civilization

QUES: Miami is noted as "the only major city in the United States conceived by a woman, Julia Tuttle", a local citrus grower and a wealthy Cleveland native. The Miami area was better known as "Biscayne Bay Country" in the early years of its growth. In the late 19th century, reports described the area as a promising wilderness. The area was also characterized as "one of the finest building sites in Florida." The Great Freeze of 1894–95 hastened Miami's growth, as the crops of the Miami area were the only ones in Florida that survived. Julia Tuttle subsequently convinced Henry Flagler, a railroad tycoon, to expand his Florida East Coast Railway to the region, for which she became known as "the mother of Miami." Miami was officially incorporated as a city on July 28, 1896 with a population of just over 300. It was named for the nearby Miami River, derived from Mayaimi, the historic name of Lake Okeechobee.
What railroad was owned by Henry Flagler?

ANS: Florida East Coast Railway

QUES: The evidence for the effectiveness of measures to prevent the development of asthma is weak. Some show promise including: limiting smoke exposure both in utero and after delivery, breastfeeding, and increased exposure to daycare or large families but none are well supported enough to be recommended for this indication. Early pet exposure may be useful. Results from exposure to pets at other times are inconclusive and it is only recommended that pets be removed from the home if a person has allergic symptoms to said pet. Dietary restrictions during pregnancy or when breast feeding have not been found to be effective and thus are not recommended. Reducing or eliminating compounds known to sensitive people from the work place may be effective. It is not clear if annual influenza vaccinations effects the risk of exacerbations. Immunization; however, is recommended by the World Health Organization. Smoking bans are effective in decreasing exacerbations of asthma.
Do smoking bans prevent workplace allergies?
