Health Education Systems Incorporated (HESI) is a United States company that provides exams and other study material to help prepare student nurses for their professional licensure exam. Schools often use HESI to help predict the students likelihood of success in tests such as the NCLEX-RN. Their Admission Assessment Exam are used as a baseline entrance criterion by some nursing schools. This exam is computerized and administered online in a four hour setting.HESI was acquired by Elsevier in 2006 to offer better services to the clients that they serve.

HEPPS or EPPS are the common names for the compound 3-[4-(2-Hydroxyethyl)-1-piperazinyl]propanesulfonic acid. It is used as a buffering agent in biology and biochemistry. The pKa of HEPPS is 8.00. Research on mice with Alzheimers disease-like amyloid beta plaques has shown that the EPPS can cause the plaques to break up, reversing some of the symptoms in the mice by YoungSoo Kim's group.

Hepatic and glial cell adhesion molecule (HEPACAM) is a protein encoded by HEPACAM gene. It was first discovered and characterised in human liver cells by Shali Shen in 2005. The protein consists of 416 amino acids, and is a member of the immunoglobulin superfamily of cell adhesion molecules. The main biological functions of HEPACAM include a) modulating cell adhesion and migration, and b) inhibiting cancer cell growth.

HEOPOP(JaeWon HEO, June 4, 1988 ~ ) is a Korean YouTube creator. He belongs to DIA TV and he opened 'Heopop Lab' on July 13 in 2016. Some people have misunderstanding about his name. They know him as a 'heopap' because of pronunciation. He usually uploads unusual experiments at Heopop Channel and daily life at Heopop life Channel. He also operate the Heopop game Channel. In addition, he has various fandom and legacies. Heopop likes to leave a video filmed with the daily life as usual hobbies. This was a motivation to start working as a YouTube creator.

HERMES 5 is a project management method for IT, services, products and business organisations and was developed by the federal administration of Switzerland. This method is an open standard available to all. Many cantons, cities, educational institutions and private sector companies have successfully introduced HERMES 5. HERMES 5 is an open eGovernment Switzerland Programme Office (eGov) standard, no. 0054 and is the standard in the Federal Administration for project management.

HEMU-430X (standing for High-Speed Electric Multiple Unit 430 km/h eXperimental) is a South Korean high-speed train intended for a maximum speed of 430 km/h (267 mph). On March 31, 2013, it achieved 421.4 km/h in a test run, making South Korea the world's fourth country after France, Japan and China to develop a high-speed train running on conventional rail above 420 km/h. The main new feature of the train compared to older South Korean high-speed trains is distributed traction. The foreseen commercial version of the train, tentatively named KTX-III, would enter regular service in 2015 with a top speed of 370 km/h (230 mph).

High efficiency particulate absolute (HEPA), originally called high-efficiency particulate absorber but also sometimes called high-efficiency particulate arresting or high-efficiency particulate arrestance, is a type of air filter. Filters meeting the HEPA standard have many applications, including use in medical facilities, automobiles, aircraft and homes. The filter must satisfy certain standards of efficiency such as those set by the United States Department of Energy (DOE). There are also HEPA filters which remove particulates from water thus nullifying the term "air" often incorrectly used. The term "absolute refers to the quality of the filter (99.97% efficient to .3 microns) rather than the medium being filtered.To qualify as HEPA by US government standards, an air filter must remove (from the air that passes through) 99.97% of particles that have a size of 0.3 µm.HEPA was commercialized in the 1950s, and the original term became a registered trademark and later a generic term for highly efficient filters.
