Steric sea level is the variation of the ocean volume due to density changes (expansion and contraction of water masses), through ocean salinity (halosteric) and ocean temperature (thermosteric) variations.

The term derives from the state's position as having ultimate power over the land, which may reach the process of compulsory acquisition or expropriation of the land. (Multilingual thesaurus on land tenure (English version)

The walk is a four-beat gait. When walking, an animals's legs follow this sequence: left hind leg, left front leg, right hind leg, right front leg, in a regular 1-2-3-4 beat. At the walk, the animal will alternate between having three or two feet on the ground. (Adapted from https://en.wikipedia.org/wiki/Horse_gait)
Note
"walk" describes a specific gait of quadruped animals, especially horses, whereas "walking" is a general term for locomotion.
Fowl typhoid, caused by Salmonella enterica subspecies enterica, serovar Gallinarum biovar Gallinarum (S. gallinarum), is widely distributed throughout the world, especially in developing countries. Fowl typhoid in chickens and turkeys is more often observed in the later growing period and in mature stock. Disease is often characterised by rapid spread with high morbidity and acute or subacute mortality. Red mites may be involved in the transmission of disease and persistence in poultry houses.

Water related (human) disease caused by a filarial worm (nematode) and occurring near fast-flowing rivers and streams in which its vector, the black-fly (Simulium spp.), breeds. In infected humans, adult worms produce microfilariae, which may sometimes invade the eyes and cause blindness (river blindness). (FAO, 2014. Fisheries and Aquaculture Department)
Green cities are defined as cities characterized as having clean air and water, running a low risk of major infectious disease outbreaks, being resilient to natural disasters, encouraging green behavior, and having a relatively small ecological impact.

Francolite is a carbonate rich variety of the mineral fluorapatite, and is present in most sedimentary phosphorites. (https://en.wikipedia.org/wiki/Francolite)
A bottom trawl is constructed like a cone-shaped net that is towed (by one or two boats) on the bottom. It consists of a body ending in a codend, which retains the catch. Normally the net has two lateral wings extending forward from the opening. The mouth of the trawl is framed by headline and groundrope. It is designed and rigged to catch species living on or near the bottom. (FAO. 2026. Fishing Gear types. Bottom trawls. Technology Fact Sheets. In: Fisheries and Aquaculture.

Wholegrain foods are foods made with grains which have been through some processing, but still have most of their nutrients. The definition of 'wholegrain food' varies from country to country, but most agree that a food is wholegrain if more than half of the ingredients in it are 'wholegrain'.

Neurochemistry is the study of chemicals, including neurotransmitters and other molecules such as psychopharmaceuticals and neuropeptides, that control and influence the physiology of the nervous system. (https://en.wikipedia.org/wiki/Neurochemistry)
