University President
A chancellor is a leader of a college or university, usually either the executive or ceremonial head of the university or of a university campus within a university system. In most Commonwealth of Nations, Commonwealth and former Commonwealth nations, the chancellor is usually a ceremonial non-resident head of the university. In such institutions, the chief executive of a university is the vice-chancellor, who may carry an additional title such as ''president'' (e.g. "president & vice-chancellor"). The chancellor may serve as chairperson of the governing body; if not, this duty is often held by a chairperson who may be known as a pro-chancellor. In many countries, the administrative and educational head of the university is known as the president, principal (academia), principal or rector (academia), rector. In the United States, the head of a university is most commonly a university president. In U.S., university systems that have more than one affiliated university or campus, ...

Analytical Chemistry
Analytical chemistry studies and uses instruments and methods to separate, identify, and quantify matter. In practice, separation, identification or quantification may constitute the entire analysis or be combined with another method. Separation isolates analytes. Qualitative analysis identifies analytes, while quantitative analysis determines the numerical amount or concentration. Analytical chemistry consists of classical, wet chemical methods and modern, instrumental methods. Classical qualitative methods use separations such as precipitation, extraction, and distillation. Identification may be based on differences in color, odor, melting point, boiling point, solubility, radioactivity or reactivity. Classical quantitative analysis uses mass or volume changes to quantify amount. Instrumental methods may be used to separate samples using chromatography, electrophoresis or field flow fractionation. Then qualitative and quantitative analysis can be performed, often with t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lehigh Valley Railroad
The Lehigh Valley Railroad was a railroad built in the Northeastern United States to haul anthracite coal from the Coal Region in Pennsylvania. The railroad was authorized on April 21, 1846 for freight and transportation of passengers, goods, wares, merchandise and minerals in Pennsylvania and the railroad was incorporated and established on September 20, 1847 as the Delaware, Lehigh, Schuylkill and Susquehanna Railroad Company. On January 7, 1853, the railroad's name was changed to Lehigh Valley Railroad. It was sometimes known as the Route of the Black Diamond, named after the anthracite it transported. At the time, anthracite was transported by boat down the Lehigh River. The railroad ended operations in 1976 and merged into Conrail along with several northeastern railroads that same year. The Lehigh Valley Railroad's original and primary route between Easton and Allentown was built in 1855. The line later expanded past Allentown to Lehigh Valley Terminal in Buffalo and pas ...

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 incor ...
