Flocculation
Flocculation, in the field of chemistry, is a process by which colloidal particles come out of suspension to sediment under the form of floc or flake, either spontaneously or due to the addition of a clarifying agent. The action differs from precipitation in that, prior to flocculation, colloids are merely suspended, under the form of a stable dispersion (where the internal phase (solid) is dispersed throughout the external phase (fluid) through mechanical agitation) and are not truly dissolved in solution. Coagulation and flocculation are important processes in water treatment with coagulation aimed to destabilize and aggregate particles through chemical interactions between the coagulant and colloids, and flocculation to sediment the destabilized particles by causing their aggregation into floc. Term definition According to the IUPAC definition, flocculation is "a process of contact and adhesion whereby the particles of a dispersion form larger-size clusters". Floccu ...

Floc (biofilm)
A floc is a type of microbial aggregate that may be contrasted with biofilms and granules, or else considered a specialized type of biofilm. Flocs appear as cloudy suspensions of cells floating in water, rather than attached to and growing on a surface like most biofilms. The floc typically is held together by a matrix of extracellular polymeric substance (EPS), which may contain variable amounts of polysaccharide, protein, and other biopolymers. The formation and the properties of flocs may affect the performance of industrial water treatment bioreactors such as activated sludge The activated sludge process is a type of biological wastewater treatment process for treating sewage or industrial wastewaters using aeration and a biological floc composed of bacteria and protozoa. It uses air (or oxygen) and microorganisms ... systems where the flocs form a ''sludge blanket''. Floc formation may benefit the constituent microorganisms in a number of ways, including protection from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Farm Labor Organizing Committee
The Farm Labor Organizing Committee (FLOC) is a labor union representing migrant farm workers in the Midwestern United States and North Carolina. History FLOC was founded in Toledo, Ohio, in 1967 by Baldemar Velasquez.Barger and Reza, ''The Farm Labor Movement in the Midwest'', 1994. A migrant worker who had worked in the fields since he was six years old, Velasquez led his first strike at the age of 12.Franklin, "Farm Workers' Group Pushes for Better Pay, Rights," ''Chicago Tribune'', April 8, 2006. By the time he was 20 years old and a college student, Velasquez had already faced numerous beatings and arrests. But in 1967, with the help of his father and others, Velasquez organized FLOC among migrant field workers picking tomatoes in Ohio."FLOC Founder to Speak on Pesticide Poisoning," ''The Monitor'', August 23, 1999; Rosenbaum, "Farm Labor Organizing Committee (FLOC): Grassroots Organizing for the Empowerment of the Migrant Farm Worker Community," ''Culture and Agriculture'' ...

Federated Learning Of Cohorts
Federated Learning of Cohorts (FLoC) is a type of web tracking. It groups people into "cohorts" based on their browsing history for the purpose of interest-based advertising. FLoC was being developed as a part of Google's Privacy Sandbox initiative, which includes several other advertising-related technologies with bird-themed names. Despite "federated learning" in the name, FLoC does not utilize any federated learning. Google began testing the technology in Chrome 89 released in March 2021 as a replacement for third-party cookies. By April 2021, every major browser aside from Google Chrome that is based on Google's open-source Chromium platform had declined to implement FLoC. The technology was criticized on privacy grounds by groups including the Electronic Frontier Foundation and DuckDuckGo, and has been described as anti-competitive; it generated an antitrust response in multiple countries as well as questions about General Data Protection Regulation compliance.
