The air from the qanat is drawn into the tunnel at some distance away and is cooled both by contact with the cool tunnel walls/water and by the transfer of latent heat of evaporation as water evaporates into the air stream. In dry desert climates this can result in a greater than 15 °C reduction in the air temperature coming from the qanat ...
Heating and then cooling a magnetized material, subjecting it to vibration by hammering it, or applying a rapidly oscillating magnetic field from a degaussing coil tends to release the domain walls from their pinned state, and the domain boundaries tend to move back to a lower energy configuration with less external magnetic field, thus ...

Olla – a ceramic jar, often unglazed, used for cooking stews or soups, for the storage of water or dry foods, or for other purposes. Pipkin – an earthenware cooking pot used for cooking over direct heat from coals or a wood fire. Palayok – a clay pot used as the traditional food preparation container in the Philippines used for cooking ...
A water heater is still sometimes called a geyser in the UK and South Africa. Maughn's invention influenced the work of a Norwegian mechanical engineer named Edwin Ruud. The first automatic, storage tank-type gas water heater was invented around 1889 by Ruud after he immigrated to Pittsburgh, Pennsylvania (US). The Ruud Manufacturing Company ...
Samovar in Tula, Russia. A samovar (Russian: самовар, IPA: [səmɐˈvar] ⓘ, lit. ' self-brewer ') is a metal container traditionally used to heat and boil water.. Although originating in Russia, the samovar is well known outside of Russia and has spread through Russian culture to other parts of Eastern Europe, as well as Western and Central and Sout
In the early 20th century, a few investigators found that igneous rocks had a remanence that was much more intense than remanence acquired in the Earth's field without heating; that heating rocks in the Earth's magnetic field could magnetize them in the direction of the field; and that the Earth's field had reversed its direction in the past.

A new approach to water in the Middle East was introduced by Strategic Foresight Group, in a report co-sponsored by the Swiss and Swedish governments titled The Blue Peace: Rethinking Middle East Water [27] Blue Peace is defined as the comprehensive, integrated and collaborative management of all water resources in a circle of countries in a ...
