The number 84 is an integer that can be described and analyzed in various mathematical contexts: 1. **Mathematical Properties**: - **Type**: It is an even number, meaning it is divisible by 2. - **Factorization**: The prime factorization of 84 is \(2^2 \times 3^1 \times 7^1\).

Resin is a sticky, flammable organic substance that is typically secreted by plants, especially trees. It is composed mainly of terpenes and other organic compounds. Resins are used by plants as a defense mechanism against injury and pathogens, as they can seal wounds and deter herbivores. In addition to its natural occurrence, resin has many industrial applications.

Resin acid refers to a group of naturally occurring organic compounds, primarily obtained from the distillation of certain plant resins, particularly those derived from coniferous trees like pine. The most common type of resin acid is abietic acid, which is a major component of the rosin obtained from pine trees. Resin acids are characterized by their chemical structure, which typically includes a bicyclic structure with carboxylic acid groups.

Resin soap refers to soap that incorporates natural resins, which are aromatic organic substances that are typically exuded by trees. These resins can be used for their fragrance, skincare benefits, or as a natural preservative. In the context of soap making, resin soap may incorporate various types of resins, such as: 1. **Frankincense** – Often used for its calming and anti-inflammatory properties.

Resinoids are concentrated aromatic substances derived from the resinous exudates of certain plants and trees. In perfumery, resinoids are valued for their rich, complex scents and are often used to create depth and warmth in fragrances. They are obtained through solvent extraction processes that separate the aromatic compounds from the resin, resulting in a thick, viscous substance that retains the character and nuances of the original resin.

Sagapenum is a plant-based substance obtained from the resin of certain species of the Ferula genus, particularly Ferula gummosa. It has traditionally been used in herbal medicine and as a flavoring agent. Sagapenum is known for its strong, aromatic properties and has been utilized in various culinary dishes, as well as in traditional remedies, particularly in Middle Eastern and Indian cultures.

Storax balsam, also known simply as storax, is a fragrant resin obtained from the bark of several species of trees in the Liquidambar genus, particularly Liquidambar styraciflua, commonly known as the sweetgum tree. Storax has been used for centuries for various purposes, including perfumery, incense, and traditional medicine. The resin has a warm, sweet, and balsamic scent, making it popular in the production of fragrances and scented products.

Tacamahac is a term that historically refers to a resin obtained from certain tropical trees, particularly species in the genus *Shorea*, which are found in regions like Southeast Asia. The resin has been used for various purposes, including traditional medicine, incense, and as a component in perfumes. In a broader context, the name "Tacamahac" has been used to refer to substances derived from the resin of trees that belong to the family Dipterocarpaceae.

Apache Jena is an open-source framework for building Semantic Web and Linked Data applications in Java. It provides a set of tools and libraries for working with RDF (Resource Description Framework), which is a standard model for data interchange. Jena is designed to enable developers to create, manipulate, and query RDF data easily. Key features of Apache Jena include: 1. **RDF Data Model**: Jena provides a comprehensive API for creating and manipulating RDF graphs and data structures.

Orbital resonance occurs when two orbiting bodies exert regular, periodic gravitational influence on each other due to their orbital frequencies being related by a ratio of small integers. This situation can lead to significant effects on their orbits, including stabilization or destabilization, changes in orbital shape, and alterations in orbital inclination. In a simple example of orbital resonance, if one object completes two orbits in the same time that another object completes one orbit, they are said to be in a 2:1 resonance.

RDFa, which stands for Resource Description Framework in Attributes, is a suite of extensions to HTML5 or other XML-based document formats that enables embedding rich metadata within web documents. It allows authors to provide structured data within their HTML or XHTML documents in a way that can be easily processed by machines, such as search engines and other applications that utilize semantic web technologies.

Redland RDF Application Framework is a set of libraries and tools designed to work with the Resource Description Framework (RDF), which is a standard model for data interchange on the web. The framework provides a versatile and flexible environment for storing, manipulating, and querying RDF data. It supports various serialization formats for RDF, such as RDF/XML, Turtle, N-Triples, and others, allowing developers to work with RDF data in a way that suits their application's needs.

SPARQL (pronounced "sparkle") is a query language and protocol used for accessing and querying data stored in Resource Description Framework (RDF) format. RDF is a standard model for data interchange on the web, which encodes information in a graph structure using triples: subject-predicate-object expressions. SPARQL allows users to: 1. **Query RDF Data**: It can retrieve and manipulate data stored in RDF format from various sources, including databases, files, and endpoints.

A Tuned Mass Damper (TMD) is a mechanical device used to reduce the amplitude of mechanical vibrations in structures, such as buildings or bridges. It consists of a mass that is suspended or mounted on a spring/damper system, which is specifically designed to counteract the vibrations produced by external forces, such as wind, seismic activity, or operational loads.

RDF (Resource Description Framework) data access refers to the methods and technologies used to retrieve, manipulate, and query data that is structured in the RDF format. RDF is a standard for representing information about resources on the web, using a graph-based model. It encodes data in triples, consisting of a subject, predicate, and object, which can represent relationships and attributes of resources.

A triplestore is a specialized database designed to store and manage data in the form of triples, which are the fundamental units of data in the Resource Description Framework (RDF). Each triple is composed of three components: 1. **Subject**: The entity being described (e.g., a person, place, or concept). 2. **Predicate**: The property or attribute of the subject (e.g., "hasAge", "isLocatedIn").

The Linked Data Platform (LDP) is a set of specifications and guidelines developed by the World Wide Web Consortium (W3C) aimed at enabling the use of Linked Data principles in building web-based applications. The core goal of LDP is to facilitate the management and interaction with linked data in a way that is consistent, robust, and interoperable across different systems.

Data Catalog Vocabulary (DCAT) is a W3C (World Wide Web Consortium) recommendation designed to provide a standard vocabulary for describing datasets and data catalogs on the web. It is particularly useful for enabling interoperability and improving the discoverability of datasets across different domains and organizations. DCAT defines a set of classes and properties that can be used to represent information about datasets and data catalogs, including: 1. **Dataset**: Represents a collection of data, often related by a common theme or subject.
