Satellite-Based Augmentation Systems (SBAS) are systems designed to enhance the accuracy, integrity, and reliability of Global Navigation Satellite System (GNSS) signals. GNSS, such as GPS (Global Positioning System), provide positioning information, but the signals can be affected by various factors like atmospheric conditions, multipath effects, and orbit errors. SBAS addresses these limitations to provide improved performance for applications that require more precise positioning.
DORIS (Doppler Orbitography and Radiopositioning Integrated by Satellite) is a satellite-based positioning system used primarily for precise orbit determination. It was developed by the French National Centre for Space Studies (CNES) in collaboration with various international partners. DORIS is particularly notable for its ability to provide accurate measurements of the satellites' orbits by using a network of ground beacons that transmit radio signals.
Global air traffic management (GATM) refers to the international framework and collaborative processes that ensure the safe, efficient, and orderly flow of air traffic across the globe. It encompasses a variety of systems, protocols, and technologies used to coordinate and manage the movement of aircraft in the airspace, both at various altitudes and across different regions and jurisdictions.
Fossil resins, commonly known as amber, are natural polymers that have undergone fossilization over millions of years. They originate from the resin secreted by various trees, particularly coniferous species, which is a sticky substance produced as a defense mechanism against pests or disease. Over time, the resin can become buried under sediment, and through processes such as heat and pressure, it hardens and transforms into a solid material.
Agarwood, also known as Oud or Aoud, is a highly valued and fragrant wood that is derived from the Aquilaria tree, particularly from species such as Aquilaria malaccensis. When the tree gets infected with a specific type of mold (Fusarium species), it responds by producing a dark, aromatic resin as a defense mechanism. This resin is what gives agarwood its distinctive scent and makes it so sought after.
Apiol, also known as parsley seed oil or 4-allyl-1,2-dimethoxybenzene, is a chemical compound primarily derived from the seeds of plants in the Apiaceae family, particularly from parsley (Petroselinum crispum). It is known for its strong aroma and is often used in traditional herbal medicine, aromatherapy, and as a flavoring agent in food products.
Austrian resin extraction typically refers to the method of collecting resin from pine trees, particularly from the species that thrive in Austria and surrounding regions. This practice has historical significance, especially in the context of producing turpentine and rosin, which have various industrial and medicinal applications. The extraction process generally involves: 1. **Tapping**: Making incisions in the bark of the pine trees to access the resin. These incisions allow the resin to flow out and collect in containers.
Balm of Gilead, often referenced in historical, medicinal, and biblical contexts, typically refers to a healing substance derived from the resin of certain plants. The term is closely associated with the biblical region of Gilead, which was known for its medicinal plants. In ancient times, Balm of Gilead was used as a remedy for various ailments, and it is mentioned in the Bible, notably in the book of Jeremiah, as a symbol of healing and comfort.
Balsam of Peru is a natural resin derived from the tree known scientifically as *Myroxylon balsamum*, which is native to Central America and parts of South America, particularly in countries like Guatemala and El Salvador. The resin is often harvested from the trunk of the tree and has a rich, warm scent that is used in various applications.
Canada balsam is a naturally occurring resin obtained from the balsam fir tree (Abies balsamea), which is native to Canada and the northeastern United States. This resin is a viscous liquid that hardens into a clear, amber-like substance upon exposure to air.
As of my last update in October 2021, "Caranna" does not appear to refer to a widely known term, brand, concept, or entity in popular culture, technology, or other relevant fields. It's possible that it may be a name, a specific product, or a concept that has emerged since then, or it could be a less common term that hasn't gained significant recognition.
The cashew is a tropical tree species, scientifically known as *Anacardium occidentale*. It is native to South America but is now grown in various tropical regions around the world, including Africa, India, and Southeast Asia. The tree produces two principal products: the cashew nut and the cashew apple. 1. **Cashew Nut**: The cashew nut is the seed of the cashew tree and is widely consumed as a snack and ingredient in various dishes.
Coniferous resin salve is a topical ointment or balm made primarily from the resin of coniferous trees, such as pine, spruce, and fir. These resins are known for their natural antiseptic, anti-inflammatory, and analgesic properties. The salve may also contain other natural ingredients, such as oils, beeswax, and essential oils, to enhance its therapeutic effects and improve its texture for easy application.
Convolvulus scammonia, commonly known as scammony, is a perennial climbing plant belonging to the bindweed family (Convolvulaceae). It is native to regions of the eastern Mediterranean, particularly in countries such as Turkey, Greece, and parts of North Africa. The plant is notable for its thick, tuberous roots, which contain a resinous sap called scammony.
Dammar gum is a natural resin obtained from various species of trees in the family Dipterocarpaceae, particularly from the genus Shorea. It is a pale yellow or white, translucent substance that has been used for various purposes throughout history. ### Uses of Dammar Gum: 1. **Art and Varnish**: Dammar gum is commonly used in the production of paints, varnishes, and other coatings due to its transparency and glossy finish when dry.
Dragon's blood refers to a blood-red resin that is derived from various plant species, most notably from the Dracaena genus and certain species of the Croton and Daemonorops genera. The resin has been used for a variety of purposes throughout history, including: 1. **Traditional Medicine**: In some cultures, dragon's blood has been used in traditional medicine for its potential healing properties. It is believed to have anti-inflammatory, antimicrobial, and astringent qualities.
Frankincense is a resin obtained from the Boswellia tree, particularly the species Boswellia sacra, Boswellia serrata, and Boswellia carterii. It has been used for thousands of years for various purposes, including religious rituals, traditional medicine, and as a component in perfumes. The resin is harvested by making incisions in the bark of the tree, allowing the milky sap to ooze out and harden into golden or yellowish-colored beads.
Furfural, also known as furfuraldehyde, is an organic compound with the formula C5H4O2. It is a colorless liquid that has a distinctive aromatic odor and is derived mainly from the hemicellulose component of plant materials, such as corn cobs, sugarcane bagasse, and wood. Furfural can be produced through the acid-catalyzed hydrolysis of pentosans—polysaccharides found in many agricultural byproducts.

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!
We have two killer features:
  1. 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-calculus
    Articles 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.
