RE: Shorthorn
A Shorthorn is a breed of domestic cattle that originated in the North East of England in the late 18th century. They are known for their versatility, as they can be raised for either milk or meat production. This breed is characterized by their short horns, red, white, or roan coat, docile temperament, and good adaptability to different climates and terrains.

through and through
Through and through is a phrase often used to emphasize that someone or something possesses a quality, characteristic, or condition to the fullest extent. Its a way of saying completely, thoroughly, totally, or in every part or aspect. For instance, saying someone is a musician through and through means that person deeply embodies the qualities of a musician in all respects.

RE: Prototypical
A prototype is an early sample, model, or release of a product built to test a concept or process. It is a term used in a variety of contexts, including semantics, design, electronics, and software programming. A prototype is generally used to evaluate a new design to enhance precision by system analysts and users. Prototyping serves to provide specifications for a real, working system rather than a theoretical one. In some design workflow models, creating a prototype (a process sometimes called materialization) is the step between the formalization and the evaluation of an idea.A prototype can also mean a typical example of something such as in the use of the derivation prototypical. This is a useful term in identifying objects, behaviours and concepts which are considered the accepted norm and is analogous with terms such as stereotypes and archetypes.
The word prototype derives from the Greek πρωτότυπον prototypon, primitive form, neutral of πρωτότυπος prototypos, original, primitive, from πρῶτος protos, first and τύπος typos, impression (originally in the sense of a mark left by a blow, then by a stamp struck by a die (note typewriter); by implication a scar or mark; by analogy a shape i.e. a statue, (figuratively) style, or resemblance; a model for imitation or illustrative example—note typical). -

RE: Nicaragua
Nicaragua, officially the Republic of Nicaragua, is the largest country in the Central American isthmus, bordering Honduras to the north and Costa Rica to the south. The country is situated between 11 and 14 degrees north of the Equator in the Northern Hemisphere, which places it entirely within the tropics. The Pacific Ocean lies to the west, and the Caribbean Sea to the east. The countrys physical geography divides it into three major zones: Pacific lowlands; wet, cooler central highlands; and the Caribbean lowlands. On the Pacific side of the country are the two largest fresh water lakes in Central America—Lake Managua and Lake Nicaragua. Surrounding these lakes and extending to their northwest along the rift valley of the Gulf of Fonseca are fertile lowland plains, with soil highly enriched by ash from nearby volcanoes of the central highlands. Nicaraguas abundance of biologically significant and unique ecosystems contribute to Mesoamericas designation as a biodiversity hotspot.
The Spanish Empire conquered the region in the 16th century. Nicaragua achieved its independence from Spain in 1821. Since its independence, Nicaragua has undergone periods of political unrest, dictatorship, and fiscal crisis—the most notable causes that led to the Nicaraguan Revolution of the 1960s and 1970s. Nicaragua is a representative democratic republic, and has experienced economic growth and political stability in recent years. In 1990, Nicaragua elected Violeta Chamorro as its president. -
RE: gravitational
In physics, gravity (from Latin gravitas weight) is a fundamental interaction which causes mutual attraction between all things with mass or energy. Gravity is, by far, the weakest of the four fundamental interactions, approximately 1038 times weaker than the strong interaction, 1036 times weaker than the electromagnetic force and 1029 times weaker than the weak interaction. As a result, it has no significant influence at the level of subatomic particles. However, gravity is the most significant interaction between objects at the macroscopic scale, and it determines the motion of planets, stars, galaxies, and even light.
On Earth, gravity gives weight to physical objects, and the Moons gravity is responsible for sublunar tides in the oceans (the corresponding antipodal tide is caused by the inertia of the Earth and Moon orbiting one another). Gravity also has many important biological functions, helping to guide the growth of plants through the process of gravitropism and influencing the circulation of fluids in multicellular organisms. Investigation into the effects of weightlessness has shown that gravity may play a role in immune system function and cell differentiation within the human body.
The gravitational attraction between the original gaseous matter in the universe allowed it to coalesce and form stars which eventually condensed into galaxies, so gravity is responsible for many of the large-scale structures in the universe. Gravity has an infinite range, although its effects become weaker as objects get farther away.
Gravity is most accurately described by the general theory of relativity (proposed by Albert Einstein in 1915), which describes gravity not as a force, but as the curvature of spacetime, caused by the uneven distribution of mass, and causing masses to move along geodesic lines. The most extreme example of this curvature of spacetime is a black hole, from which nothing—not even light—can escape once past the black holes event horizon. However, for most applications, gravity is well approximated by Newtons law of universal gravitation, which describes gravity as a force causing any two bodies to be attracted toward each other, with magnitude proportional to the product of their masses and inversely proportional to the square of the distance between them:
where F is the force, m1 and m2 are the masses of the objects interacting, r is the distance between the centers of the masses and G is the gravitational constant.
Current models of particle physics imply that the earliest instance of gravity in the universe, possibly in the form of quantum gravity, supergravity or a gravitational singularity, along with ordinary space and time, developed during the Planck epoch (up to 10−43 seconds after the birth of the universe), possibly from a primeval state, such as a false vacuum, quantum vacuum or virtual particle, in a currently unknown manner. Scientists are currently working to develop a theory of gravity consistent with quantum mechanics, a quantum gravity theory, which would allow gravity to be united in a common mathematical framework (a theory of everything) with the other three fundamental interactions of physics. -
RE: honey eater
A honey eater is a type of bird, predominantly found in Australia and New Guinea, known for feeding mostly on nectar. The term refers to any bird within the Meliphagidae family, which includes over 180 species. These birds have specially adapted brush-tipped tongues, perfect for lapping up nectar from flowers. Some honey eaters also feed on insects and spiders, fruit, and honeydew.

RE: epidural anesthesia
Epidural administration (from Ancient Greek ἐπί, , upon dura mater) is a method of medication administration in which a medicine is injected into the epidural space around the spinal cord. The epidural route is used by physicians and nurse anesthetists to administer local anesthetic agents, analgesics, diagnostic medicines such as radiocontrast agents, and other medicines such as glucocorticoids. Epidural administration involves the placement of a catheter into the epidural space, which may remain in place for the duration of the treatment. The technique of intentional epidural administration of medication was first described in 1921 by Spanish military surgeon Fidel Pagés. In the United States, over 50% of childbirths involve the use of epidural anesthesia.
Epidural anaesthesia causes a loss of sensation, including pain, by blocking the transmission of signals through nerve fibres in or near the spinal cord. For this reason, epidurals are commonly used for pain control during childbirth and surgery. The technique is considered safe and effective for providing pain relief during childbirth and surgery, and is considered more effective and safer than giving pain medication by mouth or through an intravenous line. An epidural injection may also be used to administer steroids for the treatment of inflammatory conditions of the spinal cord. It is not recommended for people with severe bleeding disorders, low platelets, or infections near the intended injection site. Severe complications from epidural administration are rare, but can include problems resulting from improper administration, as well as side effects of the medicines administered. The most common complications of epidural injections include bleeding problems, headaches, and inadequate pain control. Epidural analgesia during childbirth may also impact the mothers ability to move during labor. Very large doses of anesthetics or analgesics may result in respiratory depression.
An epidural injection may be administered at any point of the spine, but most commonly the lumbar spine, below the end of the spinal cord. The specific administration site determines the specific nerves affected, and thus the area of the body from which pain will be blocked. Insertion of an epidural catheter consists of threading a needle between bones and ligaments to reach the epidural space without going so far as to puncture the dura mater. Saline or air may be used to confirm placement in the epidural space. Alternatively, direct imaging of the injection area may be performed with a portable ultrasound or fluoroscopy to confirm correct placement. Once placed, medication may be administered in one or more single doses, or may be continually infused over a period of time. When placed properly, an epidural catheter may remain inserted for several days, but is usually removed when the use of less invasive administration methods (such as taking medication by mouth) is a viable alternative. -
RE: desmanthus
Desmanthus is a genus of flowering plants in the mimosoid clade of the pea family, Fabaceae. These plants are native to tropical and subtropical regions and are commonly found in Americas. They are known for their unique spherical or hemispherical clusters of small white or greenish-yellow flowers, and are often used in pastures, fallows, and borders of crop fields. Some species of Desmanthus are known for their high protein content and are utilized as forage crops for livestock.
