Samuel Luther Dana
Samuel Luther Dana (born 11 July 1795 in Amherst, New Hampshire – 11 March 1868 in Lowell, Massachusetts) was an American chemist. Biography He studied at Phillips Exeter Academy, and graduated from Harvard in 1813. Desirous of becoming a military engineer, he applied for an appointment to the U. S. Military Academy, but instead was commissioned a lieutenant in the 1st artillery. He served during the War of 1812 in New York and Virginia, and at its close resigned from the army. Subsequently, he studied medicine, and graduated from Harvard Medical School in 1818. From 1819 until 1826, he practised in Waltham, Massachusetts, where he was brought into intimate relations with the early cotton manufacturers of the state, and his fondness for physical science determined him to devote his attention to chemistry as applied to the manufacture and coloring of cotton goods. About 1826, he established a laboratory in Waltham for the manufacture of sulphuric acid and bleaching-salts, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amherst, New Hampshire
Amherst is a town in Hillsborough County in the state of New Hampshire, United States. The population was 11,753 at the 2020 census.

History Like many towns in New England, Amherst was founded via a land grant issued to members of the colonial militia; the land grant which led to the town's foundation was issued in 1728 to veterans of King Philip's War. A colonial settlement was established at the land grant's location five years later in 1733, being initially named "Narragansett Number 3" and later "Souhegan Number 3". In 1741, the settlement's inhabitants established a Congregational church and hired a minister to preach in the settlement. On Jan ...

Sodium Phosphate
Sodium phosphate is a generic term for a variety of salts of sodium (Na+) and phosphate (PO43−). Phosphate also forms families or condensed anions including di-, tri-, tetra-, and polyphosphates. Most of these salts are known in both anhydrous (water-free) and hydrated forms. The hydrates are more common than the anhydrous forms. Uses Sodium phosphates have many applications in food and for water treatment. For example, sodium phosphates are often used as emulsifiers (as in processed cheese), thickening agents, and leavening agents for baked goods. They are also used to control pH of processed foods. They are also used in medicine for constipation and to prepare the bowel for medical procedures. Moreover, they are used in detergents for softening water, and as an efficient anti rust solution. Adverse effects Sodium phosphates are popular in commerce in part because they are inexpensive and because they are nontoxic at normal levels of consumption. However, oral sodium ...

Physicians From Massachusetts
A physician (American English), medical practitioner (Commonwealth English), medical doctor, or simply doctor, is a health professional who practices medicine, which is concerned with promoting, maintaining or restoring health through the study, diagnosis, prognosis and treatment of disease, injury, and other physical and mental impairments. Physicians may focus their practice on certain disease categories, types of patients, and methods of treatment—known as specialities—or they may assume responsibility for the provision of continuing and comprehensive medical care to individuals, families, and communities—known as general practice. Medical practice properly requires both a detailed knowledge of the academic disciplines, such as anatomy and physiology, underlying diseases and their treatment—the ''science'' of medicine—and also a decent competence in its applied practice—the art or ''craft'' of medicine. Both the role of the physician and the meaning of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

American Journal Of Science
The ''American Journal of Science'' (''AJS'') is the United States of America's longest-running scientific journal, having been published continuously since its conception in 1818 by Professor Benjamin Silliman, who edited and financed it himself. Until 1880, it was also known as the ''American Journal of Science and Arts'', but its focus was always on natural sciences and especially on geology and related subjects. In early years, the journal was often referred to as "Silliman's Journal", and the publication became associated with Yale University due to his long tenure there (1804–1853). The editorship long remained in the family of Professor Silliman, as he was assisted by his son, Benjamin Silliman Jr., from 1838. On the death of the elder Silliman in 1864, he was succeeded as chief editor by his son-in-law, James Dwight Dana, and then from 1895 till 1926 by Dana's son Edward Salisbury Dana. Associate editors included the botanist Asa Gray and the zoologist Louis Agassiz. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
