A dispersal vector refers to any agent or mechanism that promotes the movement and distribution of organisms from one location to another. This concept is commonly used in ecology, biology, and conservation to understand how species spread and establish new populations. Dispersal vectors can include various forms of movement, such as: 1. **Natural agents**: Animals (e.g.
Propagule pressure is a term used in ecology and environmental science to describe the quantity and viability of organisms (propagules) that are introduced to a new environment. These propagules can include seeds, spores, eggs, larvae, or any dispersible stages of plants or animals. The concept of propagule pressure is significant in the study of biological invasions, as it helps to explain the likelihood and success of non-native species establishing themselves in new ecosystems.
Species distribution refers to the way in which different species are spread out across various geographic areas. It encompasses the patterns, processes, and factors that affect where species live, including both the environmental conditions and biotic (living) interactions that influence their presence and abundance in particular locales. Key aspects of species distribution include: 1. **Geographic Range**: This refers to the area where a species is found.
The 20th century saw several notable Portuguese mathematicians who made significant contributions to various fields of mathematics. Here are some prominent figures: 1. **José Champalimaud (1918-2004)**: Known more for his contributions to medicine and philanthropy, Champalimaud was also involved in mathematical research, particularly in the context of his work in medical science.
(145452) 2005 RN43 is a minor planet or asteroid that is part of the asteroid belt in our solar system. It was discovered on September 8, 2005. Like other asteroids, it is composed of rock and metal and orbits the Sun. The designation "145452" refers to its number in the sequential list of discovered minor planets, while "2005 RN43" is its provisional designation, indicating it was discovered in the year 2005.
(35671) 1998 SN165 is an asteroid that is part of the main asteroid belt, which lies between the orbits of Mars and Jupiter. It was discovered on September 24, 1998, and is classified as a near-Earth object (NEO). The asteroid is named following the convention of minor planet naming, often based on various themes including characters, events, or places of significance.
(533560) 2014 JM80 is a designation for a specific asteroid that is part of the main asteroid belt in our solar system. It was discovered in 2014 and is categorized as a member of the "Hilda" group of asteroids, which are known for their stable orbits that share similarities with Jupiter’s orbit. Asteroids like 2014 JM80 are typically small, and their characteristics can include size, orbit, and composition.
Power-to-X (P2X) refers to a suite of technologies that convert electrical energy—primarily from renewable sources—into other forms of energy or valuable chemical products. The "X" in Power-to-X can stand for various outputs, depending on the specific technology or application involved. Common forms include: 1. **Power-to-Gas (P2G)**: Converts electricity into hydrogen through electrolysis of water, or produces synthetic methane by combining hydrogen with carbon dioxide.
A Flexible AC Transmission System (FACTS) refers to a collection of technologies and devices utilized to enhance the controllability and increase the capacity of power transmission networks. FACTS devices are designed to improve the efficiency, stability, and reliability of AC transmission systems by allowing for the rapid control of power flows, voltage levels, and system stability.
The Value of Lost Load (VoLL) is an economic measure used primarily in electrical power systems and energy economics. It quantifies the economic impact of power outages by estimating the monetary value of electricity not supplied during a power interruption. Essentially, VoLL reflects how much consumers are willing to pay to avoid a power outage or how much they lose when they experience one. VoLL is typically expressed in terms of currency per unit of energy not supplied (e.g.
"Human power" can refer to a few different concepts depending on the context: 1. **Physical Power**: This refers to the strength and physical capabilities of humans. It can be measured in terms of force exerted during activities, such as lifting, running, or other forms of exertion. 2. **Human Energy**: This concept involves the ability of humans to perform work, which can include physical, mental, and emotional effort.
Honorifics in linguistics refer to words or expressions that convey respect, politeness, or social status in communication. They can take various forms, including titles, pronouns, verb forms, and other lexical items. Honorifics serve to indicate the relationship between the speaker and the listener, as well as the relative status or social hierarchy between them.
CompuServe is one of the earliest online service providers and was founded in 1969. Initially started as a computer timesharing service, it evolved into a major online service during the 1980s and 1990s, providing users with access to email, forums, news, and the internet before many people had personal access to it.
"Pol Swings" does not appear to be a widely recognized term or concept as of my last update in October 2021. It could possibly refer to a specific individual's name, a niche topic, or a newly developed concept that emerged after my last knowledge update.
Christina Goldschmidt is a prominent mathematician known for her work in probability theory, particularly in the areas of stochastic processes and random walks. She has made significant contributions to the understanding of random structures and their applications in various fields. In addition to her research, Goldschmidt is involved in teaching and mentoring students in mathematics.
"A Treatise on Probability" is a foundational work on probability theory written by the British mathematician and philosopher, John Maynard Keynes, first published in 1921. In this treatise, Keynes explores the mathematical framework of probability and its philosophical implications. The work is known for its systematic approach to the theory of probability, discussing its application in various fields, including economics.
Allan Sly is an American mathematician known for his work in probability theory, particularly in statistical physics and combinatorial structures. He has contributed significantly to the understanding of phase transitions and the behavior of random processes. Sly is notably recognized for his work on the "hard core model" and the "random cluster model," after proving the conjecture regarding the transition between uniqueness and non-uniqueness of the measures for these models.
Boris Vladimirovich Gnedenko (1912–1995) was a prominent Soviet mathematician known for his contributions to probability theory and mathematical statistics. He made significant contributions to various areas within these fields, including the study of queues, reliability theory, and stochastic processes.

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.
