A "hoop gun" is a type of toy or contraption that typically consists of a hoop or ring that can be propelled or launched, often in a playful or competitive manner. The term can refer to different types of devices depending on context. In some cases, hoop guns can be seen in fairground games where players attempt to throw a hoop over various objects. In other contexts, it may refer to a more elaborate invention or toy that uses mechanisms to launch hoops.

"Location-based firearms" typically refer to firearms that incorporate technology to restrict their use based on geographic location. This concept is part of broader efforts to improve gun safety and reduce gun violence. The idea is to leverage technology, such as GPS or geofencing, to ensure that firearms can only be used in designated areas, or to prevent their use in restricted zones (such as schools or government buildings).

The Small Arms Survey is a research project based in Geneva, Switzerland, that focuses on the global issues surrounding small arms and light weapons. Founded in 2001, the organization provides comprehensive research and analysis on the production, trade, stockpiling, and use of small arms. It aims to inform policymakers, practitioners, and the public about the impacts of small arms on security, development, and human rights.

Nitrocellulose is a highly flammable compound made from cellulose that has been chemically modified by the addition of nitric acid or other nitrogen-containing compounds. It is a type of nitroether and is classified as a nitrate ester. When cellulose (the structural component of plant cell walls) undergoes nitration, it replaces some of the hydroxyl groups (-OH) in cellulose with nitro groups (-NO2), resulting in a material that can be used in a variety of applications.

The firearm industry encompasses the design, production, distribution, and retail of firearms and ammunition. This industry includes a variety of sectors and activities related to firearms, including: 1. **Manufacturing**: Companies that produce firearms, ammunition, and related components. This includes everything from handguns, rifles, and shotguns to bullets and accessories like scopes and holsters. 2. **Retail**: Businesses that sell firearms and ammunition, including gun shops, sporting goods stores, and online retailers.

Firearm terminology encompasses the specific language and terms used to describe various aspects of firearms, ammunition, and shooting. Understanding this terminology is important for anyone involved in shooting sports, hunting, law enforcement, or firearms safety. Here's a list of common terms associated with firearms: ### General Terms - **Firearm**: Any weapon that expels a projectile through a barrel by the action of an explosive. - **Action**: The mechanism that loads, fires, and ejects cartridges in a firearm.

Gun violence refers to any violence committed with the use of a firearm. This term encompasses a wide range of incidents, including but not limited to: 1. **Homicides**: Intentional killings where a weapon is used. 2. **Suicides**: Self-inflicted gunshot wounds leading to death, which make up a significant portion of gun-related deaths in many countries.

The Tulle musket refers to a type of military firearm that originated in the early 18th century in France, specifically from the city of Tulle. The name is often associated with the Tulle Model of 1777, which was a flintlock musket used by the French army. These muskets were known for their craftsmanship and accuracy, and they were typically made with a smoothbore barrel, which was common for firearms of that era.

A "wallet gun" typically refers to a type of firearm that is designed to look like a wallet or is compact enough to fit inside a wallet. These guns are often small, easily concealable, and can be used for personal defense. Wallet guns can vary in design, but they generally resemble an everyday item, making them discreet and less noticeable. It's important to note that the legality of wallet guns varies by jurisdiction, and they may be subject to specific regulations and restrictions.

Execution by shooting typically refers to a method of capital punishment where the condemned individual is killed by firearm discharge. This method has been used historically and is often associated with military or wartime contexts, although it has also been employed in civilian judicial executions in some countries. There are a few variations of shooting execution, including: 1. **Firing Squad**: A group of trained shooters aims at the condemned individual, usually targeting the heart or vital organs to ensure a quick death.

A gun is a weapon that launches projectiles, typically using explosive force. Guns can vary widely in type, design, and intended use, but they generally fall into several categories, such as: 1. **Handguns**: Firearms designed to be held and operated with one hand, including revolvers and semi-automatic pistols.

A gunfire locator is a technology or system designed to detect and identify the location of gunfire using acoustic sensors. These systems are often used by law enforcement and military organizations to enhance situational awareness and response times in urban environments or during combat situations. Gunfire locators typically function by analyzing the sound waves produced by gunshots. They use an array of microphones placed in strategic locations to triangulate the source of the sound based on the time delays between when the sound reaches different sensors.

A Personal Defense Weapon (PDW) is a type of firearm designed for close-quarters combat and self-defense situations. PDWs typically bridge the gap between handguns and rifles, offering features suitable for personal protection while still being compact and easy to handle. Here are some key characteristics of personal defense weapons: 1. **Compact Design**: PDWs are generally smaller and lighter than traditional rifles, making them easier to carry and maneuver in confined spaces.

Small Arms and Light Weapons (SALW) refer to a category of firearms that includes small caliber weapons that are designed for individual use or can be used by small crews. The distinction typically includes: 1. **Small Arms**: This term generally refers to handheld firearms that can be operated by a single person. Examples include rifles, shotguns, pistols, and submachine guns.

The Firefox logo features a stylized, orange fox that appears to be wrapping around a blue globe. The fox is designed with a sleek and streamlined look, symbolizing speed and agility, which aligns with the browser's focus on performance and user experience. The blue globe represents the internet and global connectivity. Overall, the logo conveys a sense of modernity and friendliness, which are key attributes of the Firefox browser.

Pocket is a service that allows users to save articles, videos, and other web content to view later. It provides a way for users to curate their own reading list and access saved content from various devices, including smartphones, tablets, and computers. Originally launched as a bookmarking tool, Pocket has evolved to offer features such as offline access to saved content, tagging for organization, and recommendations based on user preferences.

The Brouwer Fixed-Point Theorem is a fundamental result in topology, specifically in the field of fixed-point theory. It states that any continuous function mapping a compact convex set to itself has at least one fixed point.

The Browder Fixed-Point Theorem is a result in functional analysis and topological fixed-point theory, named after the mathematician Felix Browder. This theorem extends the classical Brouwer Fixed-Point Theorem to more general contexts, particularly in infinite-dimensional spaces.

The Atiyah–Bott fixed-point theorem is a fundamental result in algebraic topology and differential geometry, developed by mathematicians Michael Atiyah and Raoul Bott in the context of the study of fixed points of smooth maps on manifolds.

Fluid thread breakup refers to the phenomenon where a continuous thread or filament of liquid (such as a stream of ink, paint, or other fluids) breaks into separate droplets. This process is crucial in various applications, including inkjet printing, spray painting, and fuel injection systems, where the effective atomization of liquids into fine droplets is necessary for efficient application and performance.
