Friendship!
Friendship! is a 2010 German film directed by Markus Goller.
Plot summary
Berlin 1989: After the fall of the Berlin wall, Veit (Mücke) and his friend Tom (Schweighöfer) decide to fly to San Francisco. Veit claims that he wants to travel to San Francisco because of the Golden Gate Bridge which is "The westernmost point in the world." Tom is also fascinated by the idea and goes there with his friend.
Because the money they have saved is not quite enough they both book a flight to New York. Arriving there with only 55 dollars, a few clothes and some self-made films, Tom learns the real reason for Veit's desire to travel to San Francisco: Veit's goal above all else is to see his father again, who 12 years ago fled from the GDR and whose only sign of life is an annual birthday postcard. Veit wants to wait in front of the post office in San Francisco on his birthday - to meet his father when he sends the annual birthday card to him. They decide to travel further by hitch-hiking, because the remaining money would only buy them a train ticket to New Jersey.
List of Death Note episodes
Death Note is a 37-episode anime series based on the manga series of the same title written by Tsugumi Ohba and illustrated by Takeshi Obata. Death Note aired in Japan on the Nippon Television (NTV) network every Tuesday, from October 3, 2006, to June 26, 2007. The plot of the series primarily revolves around high school student Light Yagami, who decides to rid the world of evil with the help of a supernatural notebook titled Death Note. This book causes the death of anyone whose name is written in it and is passed on to Light by the God of Death (or Shinigami) Ryuk after he becomes bored within the Shinigami world.
A three-hour "Director's Cut" compilation TV special, titled "Death Note: Relight: Visions of a God", aired on NTV a few months after the anime concluded. Although advertised to be the "complete conclusion", the popularity of the series inspired the release of a second TV special, titled "Death Note: Relight 2: L's Successors" nearly a year later. These specials recap the first and second arcs of the anime respectively, with new scenes added to fill in any plot holes resulted from omitted footage.
Friendship (Stevensville, Maryland)
Friendship is a historic home located at Stevensville, Queen Anne's County, Maryland. It is a 1 1⁄2-story dwelling of Flemish bond brick construction and was built in two stages, both dating to the 18th century. The earliest section is traditionally believed to date to the 1740s. Also on the property is a frame smoke house and dairy.
It was listed on the National Register of Historic Places in 1994.

PKA
PKA may refer to:
Acid dissociation constant
An acid dissociation constant, Ka, (also known as acidity constant, or acid-ionization constant) is a quantitative measure of the strength of an acid in solution. It is the equilibrium constant for a chemical reaction known as dissociation in the context of acid-base reactions. In aqueous solution, the equilibrium of acid dissociation can be written symbolically as:
where HA is a generic acid that dissociates into A−, known as the conjugate base of the acid and a hydrogen ion which combines with a water molecule to make an hydronium ion. In the example shown in the figure, HA represents acetic acid, and A− represents the acetate ion, the conjugate base.
The chemical species HA, A− and H3O+ are said to be in equilibrium when their concentrations do not change with the passing of time. The dissociation constant is usually written as a quotient of the equilibrium concentrations (in mol/L), denoted by [HA], [A−] and [H3O+]
In all but the most concentrated aqueous solutions of an acid the concentration of water can be taken as constant and can be ignored. The definition can then be written more simply
PKA (irradiation)
A Primary Knock-on Atom or PKA is an atom that is displaced from its lattice site by irradiation; it is, by definition, the first atom that an incident particle encounters in the target. After it is displaced from its initial lattice site, the PKA can induce the subsequent lattice site displacements of other atoms if it possesses sufficient energy, or come to rest in the lattice at an interstitial site if it does not.
Most of the displaced atoms resulting from electron irradiation and some other types of irradiation are PKAs, since these are usually below the threshold displacement energy and do not have sufficient energy to displace more atoms. In other cases like fast neutron irradiation, most of the displacements result from higher energy PKAs colliding with other atoms as they slow down to rest.
Collision Models
Atoms can only be displaced if, upon bombardment, the energy they receive exceeds a threshold energy Ed. Likewise, when a moving atom collides with a stationary atom, both atoms will have energy greater than Ed after the collision only if the original moving atom had an energy exceeding 2Ed. Thus, only PKAs with an energy greater than 2Ed can continue to displace more atoms and increase the total number of displaced atoms. In cases where the PKA does have sufficient energy to displace further atoms, the same truth holds for any subsequently displaced atom.
