The diagram is named after R. Hess who originated it in 1924. Its use dates back to at least 1948. Hess diagrams are widely used i... | https://en.wikipedia.org/wiki?curid=8729584 |

Expansion ratio The expansion ratio of a liquefied and cryogenic substance is the volume of a given amount of that substance in liquid form compared to the volume of the same amount of substance in gaseous form, at room temperature and normal atmospheric pressure. If a sufficient amount of liquid is vaporized within a ... | https://en.wikipedia.org/wiki?curid=8748291 |
Coordination isomerism is a form of structural isomerism in which the composition of the complex ion varies. In a coordination isomer the total ratio of ligand to metal remains the same, but the ligands attached to a specific metal ion change. Examples of a complete series of coordination isomers require at least two m... | https://en.wikipedia.org/wiki?curid=8750824 |
Compatibility (chemical) Chemical compatibility is a measure of how stable a substance is when mixed with another substance. If two substances can mix together and undergo a chemical reaction, they are considered incompatible. Chemical compatibility is important when choosing materials for chemical storage or reactions... | https://en.wikipedia.org/wiki?curid=8761205 |
Compatibility (chemical) For example, bleach and ammonia, both commonly used as cleaners can undergo a dangerous chemical reaction when combined with each other. Even though each of them has a similar use, care must be taken not to allows these chemicals to mix. | https://en.wikipedia.org/wiki?curid=8761205 |

Hemiepiphyte A hemiepiphyte is a plant that spends part of its life cycle as an epiphyte. The seeds of primary hemiepiphytes germinate in the canopy and initially live epiphytically. They send roots downward, and these roots eventually make contact with the ground. Secondary epiphytes are root-climbers that begin as ro... | https://en.wikipedia.org/wiki?curid=8767432 |
Voulismeno Aloni (Βουλισμένο Αλώνι, Greek: sunken threshing floor) is a sinkhole located at the feet of Mt Stroumboulas, next to the old national road, at the 14th kilometer from Heraklion to Rethymnon, on the island of Crete (35°19′48″N, 25°01′05″E). It is a ground subsidence with a circular shape up to 90 meters in d... | https://en.wikipedia.org/wiki?curid=8768354 |
External flow In fluid mechanics, external flow is such a flow that boundary layers develop freely, without constraints imposed by adjacent surfaces. Accordingly, there will always exist a region of the flow outside the boundary layer in which velocity, temperature, and/or concentration gradients are negligible. It can... | https://en.wikipedia.org/wiki?curid=8793206 |
Internal flow In fluid mechanics, internal flow is a flow for which the fluid is confined by a surface. Hence the boundary layer is unable to develop without eventually being constrained. The internal flow configuration represents a convenient geometry for heating and cooling fluids used in chemical processing, environ... | https://en.wikipedia.org/wiki?curid=8793453 |
Johann Carl Megerle von Mühlfeld was a scientist and zoologist who lived from 1765 to 1842. He worked at the Vienna natural history museum, the Naturhistorisches Museum, Wien, until he retired at the end of 1835.. He took care of the minerals and part of the Mollusc Collection, working with Andreas Xaverius Stütz. They... | https://en.wikipedia.org/wiki?curid=8798268 |
Johann Georg Megerle von Mühlfeld (July 22, 1780 in Vienna – September 15, 1831, also in Vienna) was an Austrian naturalist. From 1802 on he worked as the curator's assistant at the entomological collection of the Natural-Animal Cabinet in Vienna. He later became an official in the administration.
