Industrial wastewater treatmentIndustrial wastewater treatment describes the processes used for treating wastewater that is produced by industries as an undesirable by-product. After treatment, the treated industrial wastewater (or effluent) may be reused or released to a sanitary sewer or to a surface water in the environment. Some industrial facilities generate wastewater that can be treated in sewage treatment plants.
Integer programmingAn integer programming problem is a mathematical optimization or feasibility program in which some or all of the variables are restricted to be integers. In many settings the term refers to integer linear programming (ILP), in which the objective function and the constraints (other than the integer constraints) are linear. Integer programming is NP-complete. In particular, the special case of 0-1 integer linear programming, in which unknowns are binary, and only the restrictions must be satisfied, is one of Karp's 21 NP-complete problems.
Literary realismLiterary realism is a literary genre, part of the broader realism in arts, that attempts to represent subject-matter truthfully, avoiding speculative fiction and supernatural elements. It originated with the realist art movement that began with mid-nineteenth-century French literature (Stendhal) and Russian literature (Alexander Pushkin). Literary realism attempts to represent familiar things as they are. Realist authors chose to depict everyday and banal activities and experiences.
Data extractionData extraction is the act or process of retrieving data out of (usually unstructured or poorly structured) data sources for further data processing or data storage (data migration). The import into the intermediate extracting system is thus usually followed by data transformation and possibly the addition of metadata prior to export to another stage in the data workflow. Usually, the term data extraction is applied when (experimental) data is first imported into a computer from primary sources, like measuring or recording devices.
Social realismSocial realism is the term used for work produced by painters, printmakers, photographers, writers and filmmakers that aims to draw attention to the real socio-political conditions of the working class as a means to critique the power structures behind these conditions. While the movement's characteristics vary from nation to nation, it almost always uses a form of descriptive or critical realism. The term is sometimes more narrowly used for an art movement that flourished between the two World Wars as a reaction to the hardships and problems suffered by common people after the Great Crash.
Realism (arts)Realism in the arts is generally the attempt to represent subject matter truthfully, without artificiality and avoiding speculative and supernatural elements. The term is often used interchangeably with naturalism, although these terms are not synonymous. Naturalism, as an idea relating to visual representation in Western art, seeks to depict objects with the least possible amount of distortion and is tied to the development of linear perspective and illusionism in Renaissance Europe.
Azeotropic distillationIn chemistry, azeotropic distillation is any of a range of techniques used to break an azeotrope in distillation. In chemical engineering, azeotropic distillation usually refers to the specific technique of adding another component to generate a new, lower-boiling azeotrope that is heterogeneous (e.g. producing two, immiscible liquid phases), such as the example below with the addition of benzene to water and ethanol. This practice of adding an entrainer which forms a separate phase is a specific sub-set of (industrial) azeotropic distillation methods, or combination thereof.
American RealismAmerican Realism was a style in art, music and literature that depicted contemporary social realities and the lives and everyday activities of ordinary people. The movement began in literature in the mid-19th century, and became an important tendency in visual art in the early 20th century. Whether a cultural portrayal or a scenic view of downtown New York City, American realist works attempted to define what was real. In the U.S. at the beginning of the 20th century a new generation of painters, writers and journalists were coming of age.
