Ellen Swallow Richards
Ellen Henrietta Swallow Richards (December 3, 1842 – March 30, 1911) was an American industrial and safety engineer, environmental chemist, and university faculty member in the United States during the 19th century. Her pioneering work in sanitary engineering, and experimental research in domestic science, laid a foundation for the new science of home economics. She was the founder of the home economics movement characterized by the application of science to the home, and the first to apply chemistry to the study of nutrition. Richards graduated from Westford Academy (second oldest secondary school in Massachusetts) in 1862. She was the first woman admitted to the Massachusetts Institute of Technology. She graduated in 1873 and later became its first female instructor. Richards was the first woman in America accepted to any school of science and technology, and the first American woman to obtain a degree in chemistry, which she earned from Vassar College in 1870.

Dunstable, Massachusetts
Dunstable ( ) is a town in Middlesex County, Massachusetts, United States. The population was 3,358 at the 2020 census. Etymology Dunstable was named after its sister town Dunstable, England. There are several theories concerning its modern name. In one version, legend tells that the lawlessness of the time was personified in a thief called Dun. Wishing to capture Dun, the King stapled his ring to a post daring the robber to steal it. It was, and was subsequently traced to the house of the widow Dun. Her son, the robber, was taken and hanged to the final satisfaction that the new community bore his name. Another theory is that it comes from the Anglo-Saxon for "the boundary post of Duna". A third version is that the name is derived from ''Dunum'', or Dun, a hill, and ''Staple'', a marketplace. History Dunstable was first settled by Europeans in 1656 and was officially incorporated in 1673. It is likely named after the town of Dunstable in Bedfordshire, England, home of Edward ...

Feminist
Feminism is a range of socio-political movements and ideologies that aim to define and establish the political, economic, personal, and social equality of the sexes. Feminism incorporates the position that society prioritizes the male point of view and that women are treated unjustly in these societies. Efforts to change this include fighting against gender stereotypes and improving educational, professional, and interpersonal opportunities and outcomes for women. Feminist movements have campaigned and continue to campaign for women's rights, including the right to vote, run for public office, work, earn equal pay, own property, receive education, enter contracts, have equal rights within marriage, and maternity leave. Feminists have also worked to ensure access to contraception, legal abortions, and social integration and to protect women and girls from rape, sexual harassment, and domestic violence. Changes in female dress standards and acceptable physical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sewage Treatment Plant
Sewage treatment (or domestic wastewater treatment, municipal wastewater treatment) is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable for discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges. Sewage contains wastewater from households and businesses and possibly pre-treated industrial wastewater. There are a high number of sewage treatment processes to choose from. These can range from decentralized systems (including on-site treatment systems) to large centralized systems involving a network of pipes and pump stations (called sewerage) which convey the sewage to a treatment plant. For cities that have a combined sewer, the sewers will also carry urban runoff (stormwater) to the sewage treatment plant. Sewage treatment often involves two main stages, called primary and secondary treatment, while advanced treatment also inco ...

Lawrence Experiment Station
The Lawrence Experiment Station, now known as the Senator William X. Wall Experiment Station, was the world's first trial station for drinking water purification and sewage treatment. It was established in 1887 in Lawrence, Massachusetts. A new, 22,000 square foot building opened in 1954 at 37 Shattuck Street. In 1975, the station was designated as a National Historic Civil Engineering Landmark by the American Society of Civil Engineers. In 1993, the facility was renamed after state senator William X. Wall, who had lobbied for the construction of the new station in the 1950s. History Lawrence Station was established by the Massachusetts State Board of Health, based on the earlier work of scientists William Thompson Sedgwick and Theobald Smith who understood the linkage of water-borne germs to specific diseases. In 1886 the Massachusetts legislature required its Board of Health to adopt water pollution standards, which led to creation of the station under the direction of Hiram ...

Mine Engineering
Mining in the engineering discipline is the extraction of minerals from underneath, open pit, above or on the ground. Mining engineering is associated with many other disciplines, such as mineral processing, exploration, excavation, geology, and metallurgy, geotechnical engineering and surveying. A mining engineer may manage any phase of mining operations, from exploration and discovery of the mineral resources, through feasibility study, mine design, development of plans, production and operations to mine closure. With the process of Mineral extraction, some amount of waste and uneconomic material are generated which are the primary source of pollution in the vicinity of mines. Mining activities by their nature cause a disturbance of the natural environment in and around which the minerals are located. Mining engineers must therefore be concerned not only with the production and processing of mineral commodities, but also with the mitigation of damage to the environmen ...
