This technique is crazy! It allows to both:You actually see discrete peaks at different minute counts on the other end.
- separate gaseous mixtures
- identify gaseous compounds
It is based on how much the gas interacts with the column.
Detection is usually done burning the sample to ionize it when it comes out, and then you measure the current produced.

Source. Highly radioactive isotope of caesium with half-life of 30.17 y. Produced from the nuclear fission of uranium, TODO exact reaction, not found in nature.
The fucked thing about this byproduct is that it is in the same chemical family as sodium, and therefore forms a salt that looks like regular table salt, and dissolves in water and therefore easily enters your body and sticks to things.
Another problem is that its half-life is long enough that it doesn't lose radioactivity very quickly compared to the life of a human person, although it is short enough to make it highly toxic, making it a terrible pollutant when released.
This is why for example in the goiânia accident a girl ended up ingesting Caesium-137 after eating an egg after touching the Caesium with her hands.

. Source. Nihonium is a synthetic chemical element with the symbol Nh and atomic number 113. It is one of the superheavy elements in the periodic table and was first officially reported in 2004 by a team of Japanese scientists at the RIKEN institute. The name "Nihonium" is derived from "Nihon," which is one of the ways to say "Japan" in Japanese, reflecting the element's discovery in Japan.
Taqi ad-Din Muhammad ibn Ma'ruf, often referred to simply as Taqi ad-Din, was a prominent Arab astronomer, mathematician, and engineer during the 16th century. He was born in 1526 in Damascus in the Ottoman Empire (modern-day Syria). He is best known for his contributions to astronomy and for establishing the first observatory in the Islamic world, the Maragha Observatory, which played a pivotal role in the development of astronomical research.
The Pearson distribution, or Pearson system of distributions, is a family of continuous probability distributions that are defined based on moments, especially how the shape of the distribution is determined by its moments (mean, variance, skewness, and kurtosis). This system was introduced by Karl Pearson in the early 20th century, and it encompasses a wide range of probability distributions, including the normal distribution, beta distribution, and skewed distributions.
Data-Link Switching (DLSw) is a networking protocol that helps in the interconnection of different types of network protocols, specifically to facilitate the transmission of data over WAN (Wide Area Network) links. It was primarily developed to enable the encapsulation and transport of legacy protocols, such as IBM's SNA (Systems Network Architecture), over TCP/IP networks.
Edward H. Sussenguth was a renowned American marine biologist, particularly recognized for his work in the field of ichthyology, the study of fish. He significantly contributed to our understanding of fish taxonomy and ecology, particularly in the Atlantic Ocean. Sussenguth's research included extensive studies on the life histories and populational dynamics of various fish species. His work is important for both academic research and practical applications in fisheries management and conservation.
IBM DISOSS, or IBM Dynamic Infrastructure Services for Open Systems Software, is a set of software and tools designed to help organizations manage and optimize their IT infrastructure. It focuses on improving the performance, security, and scalability of systems, particularly in dynamic and virtualized environments. DISOSS enables better resource management, automates tasks, and enhances the overall efficiency of IT operations, supporting both traditional and cloud-based architectures.
Synchronous Data Link Control (SDLC) is a bit-oriented synchronous communication protocol used for transmitting data over point-to-point and multipoint links. It was developed by IBM in the 1970s as a way to facilitate reliable and efficient data transmission in telecommunications. ### Key Features of SDLC: 1. **Synchronous Communication**: SDLC operates synchronously, meaning that data is transmitted in a continuous stream along with a clock signal.
As of my last knowledge update in October 2023, Narayanan Chandrakumar does not appear to be a widely recognized figure in public records or notable databases. It’s possible that he could be an emerging public figure, a private individual, or associated with a specific academic, professional, or cultural context that is not broadly documented.
A **quantile-parameterized distribution** is a type of probability distribution that is characterized directly in terms of its quantiles, rather than through its probability density function (PDF) or cumulative distribution function (CDF). This approach emphasizes the distribution's quantile function, which provides a way to describe the distribution based on the values at specified probabilities.
Sweden primarily uses the metric system for measurements, which is standard in most countries around the world except for a few like the United States. Here are some of the common units of measurement used in Sweden: 1. **Length**: - Meter (m) - Centimeter (cm) - Millimeter (mm) - Kilometer (km) 2.
Alternative set theories are various mathematical frameworks that diverge from the standard set theory, primarily Zermelo-Fraenkel set theory with the Axiom of Choice (ZFC). These theories often emerge to address certain philosophical issues, resolve paradoxes, or explore alternative concepts of mathematical objects. Here is a list of some notable alternative set theories: 1. **Constructive Set Theory**: This approach, which includes theories like Intuitionistic Set Theory, emphasizes constructions and computability.
Gaussian units refer to a system of units used in electromagnetism, which is based on the Gaussian system of measurements. These units are a special case of the cgs (centimeter-gram-second) system, and they are primarily used in theoretical physics, particularly in the context of classical electrodynamics. In the Gaussian system: - The fundamental units are the centimeter (cm) for length, gram (g) for mass, and second (s) for time.
Hartree atomic units, often simply referred to as atomic units (AU), are a system of natural units used primarily in quantum mechanics and atomic physics. They simplify equations by using fundamental constants to define the units of measurement. In Hartree atomic units, the quantities are scaled so that certain fundamental physical constants take on the value of 1.
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.Figure 1. Screenshot of the "Derivative" topic page.
