Chopper pumps are a type of centrifugal pump designed specifically to handle solids and slurries found in wastewater and sewage applications. They are equipped with a chopping mechanism—usually a set of rotating blades—that reduces the size of solid materials as they enter the pump. This feature allows the pump to efficiently move a mixture of liquids and solids without clogging or damaging the pump components.
A Cartan connection is a mathematical structure that generalizes the concept of a connection on a manifold, particularly in the context of differential geometry and the study of geometric structures. It is named after the French mathematician Élie Cartan. In more technical terms, a Cartan connection can be understood as a way to define parallel transport and curvature in a setting where traditional notions of a connection (like those found in Riemannian geometry) may not apply straightforwardly.

Jury research refers to the practice of conducting studies or simulations to gather insights about how jurors may respond to evidence, arguments, and various aspects of a case presented in a legal trial. This research is often used by attorneys and legal professionals to prepare for actual trials and to shape their strategies based on the potential reactions and decision-making processes of jurors.
Cássia Rock Eller, more commonly known simply as Cássia Eller, was a Brazilian singer and songwriter, born on December 10, 1962, in Rio de Janeiro and tragically passing away on December 29, 2001. She was known for her distinctive voice and powerful performances, which blended various genres including rock, MPB (Música Popular Brasileira), and pop.
A pseudo-algebraically closed field is a concept from field theory, particularly in the area of model theory and algebraic geometry. It is a type of field that can be seen as a generalization of algebraically closed fields, but without all the restrictive properties of a complete algebraic closure.
"So Fine" is an album by the American rock duo Loggins and Messina, released in 1975. This was their fifth studio album and features a blend of rock, pop, and folk elements that the duo is known for. The album includes tracks that showcase their harmonious vocals and skilled musicianship, typical of their style during that period. Notable songs from the album include "So Fine" and "My Music.
A truss is a unit of measurement used in the field of railroad engineering and construction. Specifically, it refers to a structure that is typically made up of triangular units, which are used to support bridges, roofs, and other architectural elements. In this context, however, it must be noted that "truss" is not a standard measurement unit like meters or feet. Instead, it describes a type of structural system or design approach.
Catherine McCammon does not appear to be a widely recognized public figure or concept based on the data available up to October 2021. It's possible that she could be a private individual, a fictional character, or perhaps a local figure not covered extensively in major media or literature.
An injection pump is a critical component in diesel engines, specifically designed to deliver fuel into the combustion chamber at the precise time and in the correct amount to ensure efficient engine operation. The main functions of an injection pump include: 1. **Fuel Delivery**: It pumps fuel from the fuel tank to the engine and injects it into the combustion chamber under high pressure.
Cell engineering is a multidisciplinary field that focuses on the design, manipulation, and optimization of cells for various applications, particularly in biotechnology, medicine, and synthetic biology. It encompasses a range of techniques and approaches aimed at modifying cellular functions, behaviors, and characteristics to achieve specific goals. Key areas within cell engineering include: 1. **Genetic Engineering:** Techniques such as CRISPR-Cas9 and recombinant DNA technology are used to modify the genetic material of cells.
Frank Schlesinger refers to an individual likely known for contributions in the field of astronomy or related sciences; specifically, he is noted for his work as an American astronomer in the early 20th century. He made significant contributions to the field, particularly in the areas of celestial mechanics and observational astronomy. Schlesinger served as the director of several observatories and was involved in various astronomical research projects.
Frano Kršinić is a Croatian biologist known for his contributions to the field of marine biology and ecology. He has been involved in research related to the biodiversity of marine ecosystems, particularly in the Adriatic Sea.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
