In a combustion engine, the static compression ratio is calculated based on the relative volumes of the combustion chamber and the cylinder; that is, the ratio between the volume of the cylinder and combustion chamber when the piston is at the bottom of its stroke, and the volume of the combustion chamber when the piston is at the top of its stroke. The dynamic compression ratio is a more advanced calculation which also takes into account gasses entering and exiting the cylinder during the compression phase. The compression ratio is a fundamental specification for combustion engines.

In law, certiorari is a court process to seek judicial review of a decision of a lower court or government agency. Certiorari comes from the name of an English prerogative writ, issued by a superior court to direct that the record of the lower court be sent to the superior court for review. The term is Latin for "to be made certain", and comes from the opening line of such writs, which traditionally began with the Latin words "Certiorari volumus...".
The esophagus, or oesophagus, informally known as the food pipe or gullet, is an organ in vertebrates through which food passes, aided by peristaltic contractions, from the pharynx to the stomach. The esophagus is a fibromuscular tube, about 25 cm (10 in) long in adults, which travels behind the trachea and heart, passes through the diaphragm and empties into the uppermost region of the stomach. During swallowing, the epiglottis tilts backwards to prevent food from going down the larynx and lungs. The word oesophagus is from Ancient Greek οἰσοφάγος (oisophágos), from οἴσω (oísō), future form of φέρω + ἔφαγον.
Lower Egypt is the northernmost region of Egypt, which consists of the fertile Nile Delta between Upper Egypt and the Mediterranean Sea, from El Aiyat, south of modern-day Cairo, and Dahshur. Historically, the Nile River split into seven branches of the delta in Lower Egypt. Lower Egypt was divided into nomes and began to advance as a civilization after 3600 BC. Today, it contains two major channels that flow through the delta of the Nile River.

An upper house is one of two chambers of a bicameral legislature, the other chamber being the lower house. The house formally designated as the upper house is usually smaller and often has more restricted power than the lower house. A legislature composed of only one house is described as unicameral.
A lower house is one of two chambers of a bicameral legislature, the other chamber being the upper house.
Letter case is the distinction between the letters that are in larger upper case or capitals and smaller lower case in the written representation of certain languages. The writing systems that distinguish between the upper and lower case have two parallel sets of letters, with each letter in one set usually having an equivalent in the other set. The two case variants are alternative representations of the same letter: they have the same name and pronunciation and are treated identically when sorting in alphabetical order.
A Member of the Legislative Assembly (MLA) is a representative elected by the voters of an electoral district (constituency) to the legislature of State government in the Indian system of government.

The abdomen is the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. The abdomen is the front part of the abdominal segment of the trunk. The area occupied by the abdomen is called the abdominal cavity. In arthropods it is the posterior tagma of the body; it follows the thorax or cephalothorax.

The spinal cord is a long, thin, tubular structure made up of nervous tissue, which extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. It encloses the central canal of the spinal cord, which contains cerebrospinal fluid. The brain and spinal cord together make up the central nervous system (CNS). In humans, the spinal cord begins at the occipital bone, passing through the foramen magnum and entering the spinal canal at the beginning of the cervical vertebrae. The spinal cord extends down to between the first and second lumbar vertebrae, where it ends. The enclosing bony vertebral column protects the relatively shorter spinal cord. It is around 45 cm (18 in) in men and around 43 cm (17 in) long in women. The diameter of the spinal cord ranges from 13 mm in the cervical and lumbar regions to 6.4 mm in the thoracic area.
The Oecophorinae are the nominate subfamily of moths in the concealer moth family (Oecophoridae). They are part of the insufficiently studied superfamily Gelechioidea, and like their relatives, the circumscription of this taxon is disputed.
In anatomy, the mandible, lower jaw or jawbone is the largest, strongest and lowest bone in the human facial skeleton. It forms the lower jaw and holds the lower teeth in place. The mandible sits beneath the maxilla. It is the only movable bone of the skull. It is connected to the temporal bone by the temporomandibular joint.
