The Center for Applied Linguistics (CAL) is a nonprofit organization based in Washington, D.C. Founded in 1959, CAL focuses on improving communication and understanding across languages and cultures. It conducts research, provides resources, and offers training related to language education, bilingualism, multilingualism, language assessment, and language policy, among other topics. CAL's work often involves collaborating with educators, policymakers, and researchers to develop programs and materials that address the needs of diverse language communities.

The Central Asian Nuclear Weapon Free Zone (CANWFZ) is an international treaty aimed at establishing a region in Central Asia free of nuclear weapons. It covers the five Central Asian countries: Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan. The treaty was signed in 2006 and came into effect in 2009.

George Samuel Hurst does not appear to be a widely recognized public figure or entity in popular discourse as of my last update in October 2023. It's possible that he is a private individual or a lesser-known figure in a specific field.

The Centre for Mechanochemical Cell Biology (CMCB) is an interdisciplinary research center that focuses on the fundamental mechanisms of cell biology, particularly the physical and chemical processes that govern cell behavior and function. It typically brings together researchers from various fields such as biology, physics, chemistry, and engineering to study how mechanical forces and chemical signals influence cellular processes, including cell movement, division, and communication. Research areas may include: - Mechanotransduction: Understanding how cells sense and respond to mechanical stimuli.

The Century Flyer is a type of wooden roller coaster manufactured by the roller coaster company Custom Coasters International (CCI). It is known for its classic, nostalgic design and smooth ride experience that often features a series of twists, turns, and drops. The Century Flyer is designed to evoke the feel of traditional wooden coasters while incorporating modern engineering techniques to enhance safety and ride quality. Additionally, "Century Flyer" might refer to other entities, such as a specific model of a train or a bicycle.

César Camacho can refer to different individuals or contexts, but one prominent figure associated with that name is César Camacho Quiroz, a Mexican politician who has served in various capacities within the Institutional Revolutionary Party (PRI). He has held important positions in Mexican politics, including serving as a member of the Chamber of Deputies and as the party's leader in different capacities.

A pullback motor is a type of mechanism commonly used in toys, particularly in small model cars, trucks, and other vehicles. It operates by using a simple wound spring mechanism to store energy. Here's how it works: 1. **Winding**: When you pull the toy backward, it winds a small internal spring or gear mechanism. This action stores potential energy in the form of the wound spring.

Change ringing is a method of ringing bells in a tower, where a set of tuned bells is rung in a series of mathematical sequences or patterns called "changes." The main objective is to ring the bells in such a way that no two sequences are the same, creating a complex and interesting pattern of sound. The bells are typically rung by a group of ringers who pull on ropes attached to the bells.

Chair tiling, also known as chair graph tiling, is a type of mathematical tiling problem that involves covering a region using shapes that are analogous to a chair. Specifically, it typically refers to using small polygons to fill a larger polygonal area without overlaps or gaps, adhering to certain constraints based on the shapes.

"Channel use" can refer to various concepts depending on the context. Here are a few possible interpretations: 1. **Marketing and Distribution**: In marketing, channel use refers to the strategies and methods businesses employ to deliver their products or services to customers. This includes choosing between direct channels (like selling directly through a website) or indirect channels (like using retailers or distributors).

Chaplygin gas is a theoretical model in cosmology that describes a type of fluid characterized by a specific equation of state. It is named after the Russian mathematician Sergey Chaplygin, who introduced the concept in the early 20th century.

Charles Fox (1900–1968) was a prominent British mathematician known for his work in the field of numerical analysis, especially in the area of asymptotic expansions and special functions. He made substantial contributions to the understanding of various mathematical functions and their properties. One of his notable works includes the development of Fox's H-function, which generalizes several important functions encountered in applied mathematics.

Charles Oatley (1912–2013) was an influential British physicist and engineer, best known for his contributions to the field of electron microscopy. He is considered a pioneer in the development of high-resolution transmission electron microscopy, which has been crucial for advances in materials science and biology. Oatley’s work laid the groundwork for using electron microscopes in various applications, including the observation of biological specimens at a molecular level.

Charles V. Shank may refer to a prominent figure known for his contributions to the field of applied science and engineering, particularly in the area of electrical engineering and photonics. He is a noted academic and researcher, having served as a professor and holding various administrative roles at institutions such as the University of California, Berkeley. Shank's work has focused on ultrafast laser techniques and their applications in physics and materials science.

Charles S. Hastings is not widely recognized as a public figure or notable individual in mainstream contexts. There may be various individuals with that name in different fields, such as academia, business, or other areas, but without specific context, it's difficult to provide a precise answer. If you have more information or context about Charles S.

Chemical numbering schemes refer to systematic methods used to identify and organize the unique arrangement of atoms and functional groups in a chemical compound, as well as to provide a clear and unambiguous way to refer to each component of a compound or molecules.
