Chemical Oxygen Demand (COD) is a measure of the amount of organic compounds in water or wastewater that can be oxidized by a strong chemical oxidant. It is an important parameter used to evaluate water quality, particularly in the context of wastewater and effluent treatment. COD is expressed in units of milligrams of oxygen consumed per liter of sample (mg O₂/L).
Alessandro Padoa is primarily known as an Italian mathematician, particularly recognized for his work in mathematical logic and related fields.
Systole refers to the phase of the cardiac cycle during which the heart muscles contract, resulting in the pumping of blood out of the heart. This phase occurs in both the atria and the ventricles but is most commonly associated with ventricular systole, where the ventricles contract to push blood into the aorta and pulmonary artery.
Rémi Abgrall is a French professional athlete known for his involvement in the sport of rugby. He has played for various teams and may have gained recognition in the rugby community for his skills on the field.

In chess, a checkmate occurs when a player's king is in a position to be captured ("in check") and there are no legal moves available to escape the threat of capture. This means the opposing player has effectively won the game, as checkmate ends the game immediately. Here are the key aspects of checkmate: 1. **Check**: This is the initial condition where the king is under threat of capture in the next move.
A Total Station is a surveying instrument that combines the functions of an electronic theodolite and an electronic distance measuring (EDM) device. It is used to measure angles and distances in order to determine precise positions in three-dimensional space. Total stations are widely used in construction, civil engineering, and land surveying for tasks such as site surveys, mapping, and topographic surveys.
Phrap is a software tool used for assembling DNA sequences, particularly in the context of sequence analysis and genomics. It is part of the CAP3 assembly program, which is commonly used for assembling DNA sequences derived from high-throughput sequencing technologies. Phrap employs algorithms that utilize information from overlapping DNA sequences to construct longer contiguous sequences, known as contigs. The tool can manage sequences from various sources, including those generated by Sanger sequencing.
ArXiv is a free distribution repository and an open-access archive for scholarly articles in various fields of science, mathematics, computer science, quantitative biology, quantitative finance, statistics, electrical engineering, and economics. It was established in 1991 and is maintained by Cornell University Library. Researchers and scientists use ArXiv to disseminate their findings and share preprints—versions of scholarly papers that precede formal peer review and publication.
"Bevel" can refer to several different concepts depending on the context: 1. **Geometry**: In geometry, a bevel is an edge that is not perpendicular to the faces of an object. Instead, it is sloped or angled. This can be seen in woodworking, metalworking, and manufacturing where an edge is cut at an angle to create a beveled edge.
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!
Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.
