Definition: The actinograph refers to a special kind of photographic material used to record images, usually in color or black-and-white. It's made of thin film stretched between two glass plates, which are then coated with an adhesive compound. This type of photography is often called "glass" because the film and the backing plate are made out of glass. Actinographs can be created using a variety of materials, including plastic, metal, or even paper. They're commonly used for marketing, advertising, or to create visual elements in websites or social media posts. Some examples include: 1.

Glasses

- These are flat sheets of transparent material that you can fold in half and press together to form an image. 2.

Covers

- Similar to a glass, these are also made of transparent material. They're used to create decorative elements on packaging or other surfaces. 3.

Stickers

- Often found on clothing or accessories, they are thick plastic strips that can be stretched out and stuck onto surfaces. 4.

Masks

- This type of actinograph is often used for creating a 3D effect or for adding texture to an object. 5.

Papers

- Used for printing images or for decorative purposes, papers with transparent areas are commonly used in advertising. In summary, actinographs are special types of photographic material that can be used to record images or other visual content by stretching thin film between two glass plates and coating them in adhesive. The exact definition will depend on the context. For example, a "glass" actinograph could refer to any transparent plate where the film is stretched between the glass surface and an adhesive compound. Additionally, the specific type of actinograph used can be influenced by its intended purpose and the materials available for making it.

Definition: Actinogamic, a term used to denote an organism that has two pairs of actin fibers. The human body contains multiple muscles in the skeletal system (e.g., back, shoulder, chest). These muscle fibers contain two filaments: actin and myofilament. The actin filament is the primary contractile component of muscle fiber. Myofilaments are responsible for pulling the muscle fiber along its axis as it contracts. Actinomyosins are a family of proteins that are primarily found in muscle fibers (e.g., skeletal, cardiac). They possess two domains - one to form filaments and another to facilitate attachment of actin and myofilament. Myofilin is a type of actin protein. It is responsible for linking the actin filament with other actin molecules. Actinotipin is an enzyme that binds to the actin and myofibrillar proteins in muscle fibers and activates a series of post-translational modifications on actin, which leads to the formation of new filaments by activation of myofilaminase. This process results in the synthesis of multiple actin filaments. Myosin is an ATP-dependent protein that performs ATP hydrolysis and forms monomeric myofibrils (filaments) by binding to actin and myofilament proteins. It also promotes myofilaments to attach to muscle fiber membrane, form myosin motors, and generate contractility. The study of the structure and function of myofilins is essential for understanding muscle physiology and disease.

Definition: Actinography, also known as actigraphy or photographic actigraphy, refers to the process of photographically documenting acts of human motion using light. It involves a series of photographs taken in sequence, typically with a lens placed at a distance from the subject, allowing for an accurate and detailed record of their movements. The actigraphy technique is commonly used in forensic science and criminal justice, but it has also been used in non-criminal settings to document various activities such as medical procedures, public speeches, or personal photographs. Actinography can be used to capture both natural movements (such as walking, running, and jumping) and human actions. It involves the use of a camera, light source, and a photographic film process. The actigraphy is typically conducted with a pair of binoculars, or other suitable optical devices, placed at a distance from the subject. These binoculary lenses focus on the eyes of the subjects, allowing them to be photographed from different angles while maintaining their natural state. The objective of actigraphy is to record the movement in real time and document it for analysis purposes. The photographs are taken over several seconds or minutes, with each frame being a snapshot of the subject's actions. This process ensures that the motion is captured accurately without artifacts such as blurring due to lighting conditions or movement blur. Actinography can be used for various forensic investigations, including crime scenes, medical procedures, and public speeches. It has been used extensively in many legal systems worldwide to document evidence and evidence-related events.
