Hever Railway Station
Hever railway station is on the branch of the Oxted line in southern England and serves Hever in Kent. It is from . The station is managed by Southern. Hever Castle is about a walk from the station. History The station was opened by the London, Brighton and South Coast Railway on 1 October 1888. It passed onto the Southern Railway in 1923 and to British Railways in 1948. The signal box was built into the station building and remained in use until the line was resignalled in January 1990 when the station was destaffed. Facilities Hever station is unstaffed and tickets must be bought from the self-service ticket machine at the station. The station has passenger help points and covered seating areas available on both platforms. The station has a small cycle rack located on the Uckfield bound platform. The Uckfield bound platform is accessible without steps however the London bound platform is only reachable by the stepped footbridge so isn't accessible. Services All ser ...

Hybrid Electric Vehicle
A hybrid electric vehicle (HEV) is a type of hybrid vehicle that combines a conventional internal combustion engine (ICE) system with an electric propulsion system ( hybrid vehicle drivetrain). The presence of the electric powertrain is intended to achieve either better fuel economy than a conventional vehicle or better performance. There is a variety of HEV types and the degree to which each function as an electric vehicle (EV) also varies. The most common form of HEV is the hybrid electric car, although hybrid electric trucks (pickups and tractors), buses, boats and aircraft also exist. Modern HEVs make use of efficiency-improving technologies such as regenerative brakes which convert the vehicle's kinetic energy to electric energy, which is stored in a battery or supercapacitor. Some varieties of HEV use an internal combustion engine to turn an electrical generator, which either recharges the vehicle's batteries or directly powers its electric drive motors; this combinatio ...

Hydrogen Electric Vehicle
A fuel cell vehicle (FCV) or fuel cell electric vehicle (FCEV) is an electric vehicle that uses a fuel cell, sometimes in combination with a small battery or supercapacitor, to power its onboard electric motor. Fuel cells in vehicles generate electricity generally using oxygen from the air and compressed hydrogen. Most fuel cell vehicles are classified as zero-emissions vehicles that emit only water and heat. As compared with internal combustion vehicles, hydrogen vehicles centralize pollutants at the site of the hydrogen production, where hydrogen is typically derived from reformed natural gas. Transporting and storing hydrogen may also create pollutants. Fuel cells have been used in various kinds of vehicles including forklifts, especially in indoor applications where their clean emissions are important to air quality, and in space applications. The first commercially produced hydrogen fuel cell automobile, the Hyundai ix35 FCEV, was introduced in 2013, the Toyota Mirai followed ...

Hummer EV
The GMC Hummer EV (also known as Hummer EV and badged as HEV) is a line of battery electric full-size vehicles produced by General Motors under the GMC marque, and its own sub-brand. The Hummer EV line was introduced in October 2020 with the unveiling of the pickup truck (SUT) model. The sport utility vehicle (SUV) model was unveiled in April 2021. As of Q3 2022, 783 units have been delivered to customers. History Origins The GMC Hummer EV originates from the discontinued Hummer brand (stylized HUMMER), previously owned by General Motors. AM General created the hummer brand. Previously, they manufacturered the HUMVEE light military vehicle. On June 1, 2009, the company revealed that the Hummer brand would be discontinued as a part of the General Motors bankruptcy announcement. Trims Edition 1 Arriving to the production line in 2022, Edition 1 is the sole model available for the first year and is considered to be a limited edition that was available for pre- ...

Hendra Virus
Hendra virus (HeV), scientific name ''Hendra henipavirus'', is a bat-borne virus that is associated with a highly fatal infection in horses and humans. Numerous disease outbreaks in Australia among horses have been caused by Hendra virus. The Hendra virus belongs to the genus ''Henipavirus'', which also contains the Nipah virus, which has also caused disease outbreaks. Pathology Flying foxes experimentally infected with the Hendra virus develop a viraemia and shed the virus in their urine, faeces and saliva for approximately one week. There is no other indication of an illness in them. Symptoms of Hendra virus infection of humans may be respiratory, including hemorrhage and edema of the lungs, or in some cases viral meningitis. In horses, infection usually causes one or more of pulmonary oedema, congestion and neurological signs. Ephrin B2 has been identified as the main receptor for the henipaviruses. Transmission Flying foxes have been identified as the reservoir host of Hend ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hepatitis E Virus
The hepatitis E virus (HEV) is the causative agent of hepatitis E. It is of the species ''Orthohepevirus A.'' Globally, approximately 939 million corresponding to 1 in 8 individuals have ever experienced HEV infection. About 15–110 million individuals have recent or ongoing HEV infection. The virus particle was first seen in 1983, but was only molecularly cloned in 1989. Genome and proteome ''Orthohepevirus A'' can be classified into eight different genotypes from different geographical regions: genotype 1 (Asia), genotype 2 (Africa and Mexico), genotype 3 (Europe and North America), genotype 4 (Asia); genotypes 5 and 6 have been detected in Asian wild boar and genotypes 7 and 8 in camels.Schlauder, G. G. & Mushahwar, I. K. (2001) Genetic heterogeneity of hepatitis E virus. J Med Virol 65, 282–92 The viral genome is a single strand of positive-sense RNA that is about 7200 bases in length.

High Endothelial Venules
High endothelial venules (HEV) are specialized post-capillary venous swellings characterized by plump endothelial cells as opposed to the usual thinner endothelial cells found in regular venules. HEVs enable lymphocytes circulating in the blood to directly enter a lymph node (by crossing through the HEV). Table 14-1 In humans, HEVs are found in all secondary lymphoid organs (with the exception of spleen, where blood exits through open arterioles and enters the red pulp), including hundreds of lymph nodes dispersed in the body, tonsils and adenoids in the pharynx, Peyer's patches (PIs) in the small intestine, appendix, and small aggregates of gut-associated lymphoid tissue, lymphoid tissue in the stomach and large intestine. In contrast to the endothelial cells from other vessels, the high endothelial cells of HEVs have a distinctive appearance, consisting of a cuboidal morphology (biology), morphology and with various receptors to interact with leukocytes (express specialized ligand ...

Hevein (protein)
Pro-hevein (Alternative name: Major hevein, gene name: HEV1) is a wound-induced and a lectin-like protein from ''Hevea brasiliensis'' (rubber tree) where it is involved in the coagulation of latex. The 187 amino-acid propeptide pro-hevein is cleaved in two fragments: a N-terminal 43 amino-acid Hevein bearing a chitin-binding type-1 domain (also known as CBM18 carbohydrate-binding module) that binds to chitin and a 138 amino-acid Win-like protein bearing a Barwin domain. It has antifungal properties. Role of hevein in latex allergy Hevein is the main IgE-binding epitope of the major latex allergen prohevein as are hevein-like protein domains in fruit class I chitinases. Therefore it is a possible cause for allergen cross-reactivity between latex and banana or other fruits like chestnuts or avocadoes. Hevein-like genes can be found in many plants including ''Arabidopsis thaliana''. Hevein is called ''Hev b 6'' under the WHO allergen nomenclature. There are three entries un ...

High-energy Visible Light
High-energy visible light (HEV light) is high-frequency, high-energy light in the violet/blue band from 400 to 450 nm in the visible spectrum, which has a number of biological effects, including those on the eye. HEV light may be a cause of age-related macular degeneration. Some sunglasses and beauty creams specifically block HEV, for added marketing value. Currently, a 2019 report by France's Agency for Food, Environmental and Occupational Health & Safety (ANSES) supports the 2010 result on the adverse effect of blue LED light (400-450 nm spike) on the eye, which can lead to impaired vision. It highlights short-term effects on the retina linked to intense exposure to blue LED light, and long-term effects linked to the onset of age-related macular degeneration. Although few studies have examined occupational causes of macular degeneration, they show that long-term sunlight exposure, specifically its blue-light component, is associated with macular degeneration in outdo ...
