H. H. Holmes

Herman Webster Mudgett (May 16, 1861 – May 7, 1896), better known under the name of Dr. Henry Howard Holmes or more commonly just H. H. Holmes, was one of the first documented serial killers in the modern sense of the term. In Chicago, at the time of the 1893 World's Columbian Exposition, Holmes opened a hotel which he had designed and built for himself specifically with murder in mind, and which was the location of many of his murders. While he confessed to 27 murders, of which nine were confirmed, his actual body count could be up to 200. He brought an unknown number of his victims to his World's Fair Hotel, located about 3 miles (4.8 km) west of the fair, which was held in Jackson Park. Besides being a serial killer, H. H. Holmes was also a successful con artist and a bigamist.

Early life

Holmes was born as Herman Webster Mudgett in Gilmanton, New Hampshire, on May 16, 1861, to Levi Horton Mudgett and Theodate Page Price, both of whom were descended from the first English settlers in the area. Mudgett was his parents' third-born child; he had an older sister Ellen, an older brother Arthur and a younger brother Henry. Holmes's father was a farmer from a farming family, and his parents were devout Methodists. According to the 2007 Most Evil profile on Holmes, his father was a violent alcoholic. Holmes excelled in school, which led to bullying by jealous classmates. In an attempt to scare him, the bullies forced him into the local doctor's office and made him stand face to face with a human skeleton, and placed the skeleton's hands on his face. Holmes later recalled that at first he was frightened, but then found the experience fascinating. He also wrote that the experience cured him of his fears. Holmes soon became obsessed with death and later started a hobby of dissecting animals.

Hilmar Örn Hilmarsson

Hilmar Örn Hilmarsson (Icelandic: [ˈhɪlmar ˈœr̥tn̥ ˈhɪlmarsɔn]; born 23 April 1958), also known as HÖH, is a musician, an art director, and allsherjargoði (chief goði) of Ásatrúarfélagið ("the Ásatrú Association").

Hilmar Örn Hilmarsson was a pioneer in the use of computers when composing music and cleared the path for new ideas in recording and arrangements. He has worked on ambitious, experimental and original projects with various musicians, such as Psychic TV, Current 93, Sigur Rós, Steindór Andersen and Eivør Pálsdóttir.

From early bands to the birth of Þeyr

From 1972 to 1975 he was playing drums in a school band called Fatima with guitarist Jóhannes Helgason, bassist Birgir Ottóson and singer Guðmundur Eyjólfsson. In 1974 singer Eiríkur Hauksson replaced Guðmundur and guitarist Sigurgeir Sigmundsson joined them and a year after they broke up.

.375 H&H Magnum

The .375 Holland & Holland Magnum (9.5×72mmB) is a medium-bore rifle cartridge. The .375 H&H was only the second cartridge ever to feature a belt, now common among magnum rounds. On these new rimless cartridges the belt replaced the rim in ensuring the correct headspace, which otherwise might be unreliable, given the narrow shoulder of the cartridge case. The British company Holland & Holland introduced the cartridge in 1912 as the .375 Belted Rimless Nitro-Express. It initially used cordite propellant which was made in long strands – hence the tapered shape of this cartridge, which also ensured smooth chambering and extraction from a rifle's breech.

The .375 H&H often is cited as one of the most useful all-round rifle cartridges, especially in shooting large and dangerous game. With relatively light bullets in the region of 235 to 270 grains (15 to 17 g), it is a flat-shooting, fairly long-range cartridge ideal for use on light to medium game, whereas with heavy bullets of 300 grains (19 g) and greater, it has the punch necessary for large, thick-skinned dangerous game. In many regions with thick-skinned dangerous game animals, the .375 H&H is seen as the minimum acceptable caliber, and in many places (in Africa, primarily) it is now the legal minimum for hunting such game. African game guides, professional hunters, and cullers of dangerous game have repeatedly voted the .375 H&H as their clear preference for an all-round caliber if they could only have one rifle. A similar preference has been expressed by Alaskan game guides for brown bear and polar bear country

Henderson–Hasselbalch equation

In chemistry, the Henderson–Hasselbalch equation describes the derivation of pH as a measure of acidity (using pK_a, the negative log of the acid dissociation constant) in biological and chemical systems. The equation is also useful for estimating the pH of a buffer solution and finding the equilibrium pH in acid-base reactions (it is widely used to calculate the isoelectric point of proteins).

The equation is given by:

Here, [HA] is the molar concentration of the undissociated weak acid, [A⁻] is the molar concentration (molarity, M) of this acid's conjugate base and pK_a is −log₁₀K_a where K_a is the acid dissociation constant, that is:

In these equations, A⁻ denotes the ionic form of the relevant acid. Bracketed quantities such as [base] and [acid] denote the molar concentration of the quantity enclosed.

For bases
