A definite description is a linguistic expression that refers to a specific individual or entity that is usually identifiable through the context in which it is used. The most common example is the use of "the" followed by a noun, as in "the tallest building" or "the president of the United States." The key characteristic of a definite description is that it suggests uniqueness; it implies that there is one particular referent that satisfies the description.
A Quaternion-Kähler manifold is a type of Riemannian manifold that has some special geometric properties related to both quaternionic structures and Kähler geometry. It is a higher-dimensional generalization of Kähler manifolds and carries significant implications in differential geometry and theoretical physics, particularly in the context of supersymmetry and string theory.
Demographic and Health Surveys (DHS) are extensive surveys that collect data on population, health, and nutrition indicators in developing countries. They are designed to provide high-quality and nationally representative data that are essential for policymakers, researchers, and program managers in the fields of public health, demographic studies, and development planning.
A demulsifier is a chemical agent used to separate emulsions, which are mixtures of two or more immiscible liquids, typically oil and water. In many industrial processes, these emulsions can form during activities such as oil extraction, refining, or wastewater treatment. Demulsifiers work by destabilizing the emulsion, allowing the individual components to separate more easily.
The Department of History and Philosophy of Science (HPS) at the University of Cambridge is an academic division that focuses on the historical and philosophical aspects of scientific knowledge and practice. It combines the study of the history of science with an examination of the philosophical questions related to scientific methods, concepts, and ethics.
In chemistry, deposition refers to the process by which a substance transitions from a gas directly to a solid, bypassing the liquid state. This phase transition is the reverse of sublimation, where a solid becomes a gas without passing through the liquid phase. Deposition typically occurs under specific conditions of temperature and pressure, usually at low temperatures and high pressures. It is an important process in various natural phenomena and industrial applications.
Quique Somenzini is not a widely recognized figure, as of my last knowledge update in October 2023. However, if you have more context about who Quique Somenzini is—such as their profession or field—they might be a person of interest in a specific area such as sports, arts, business, etc. Without additional details, it's challenging to provide a comprehensive answer. Please provide more context or check if the name is spelled correctly!
The Descriptive Color Names Dictionary is a resource that provides names for colors based on descriptive terms rather than standard color codes or technical specifications. These names are often more relatable and memorable, making them useful for a variety of applications such as art, design, fashion, and marketing. In such a dictionary, colors may be described using a combination of familiar terms that relate to nature, emotions, or objects (e.g., "sky blue," "rose red," "forest green").
The Desmic system, introduced by the Swiss company Desmic AG, is a comprehensive solution for managing medical data, particularly in the field of surgery. It encompasses various functionalities, including the documentation of surgical procedures, management of patient data, and compliance with regulatory standards. Key features of the Desmic system typically include: 1. **Documentation Management**: Provides tools for surgeons and medical professionals to document surgical processes, ensuring that all necessary information is captured accurately.
Developmental Systems Theory (DST) is an interdisciplinary framework that seeks to understand the complexities of development—particularly in biological and psychological contexts—by emphasizing the dynamic interactions between genetics, environment, and individual behavior over time. It stands in contrast to traditional genetic or environmental determinism by viewing development as a product of a continuous interplay among various factors.

Diecast Collector is often referred to as a magazine, publication, or community that focuses on diecast model cars and collectibles. It typically features articles, reviews, news, and information about various diecast models produced by different manufacturers. The content may include profiles of popular diecast brands, insights into collecting, tips for maintaining and displaying collections, and interviews with collectors or industry experts.
A diffeomorphism is a concept from differential geometry and is used to describe a certain type of relationship between smooth manifolds. More formally, a diffeomorphism is a bijective (one-to-one and onto) function between two smooth manifolds that is smooth (infinitely differentiable) and whose inverse is also smooth.
A differential analyzer is an early type of analog computer designed to solve differential equations. It uses mechanical, electrical, or hydraulic systems to simulate the behavior of dynamic systems that can be described by differential equations. The primary purpose of a differential analyzer is to perform integration; this is because many physical processes can be described as a series of integrals or differential equations.
Diffusion current refers to the flow of charge carriers (such as electrons or holes in a semiconductor) due to a concentration gradient. In a material, charge carriers tend to move from regions of high concentration to regions of low concentration, similar to how substances diffuse from areas of higher concentration to areas of lower concentration in a fluid.
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.
