Network compartment. Network Compartmentalization, the division of network functionality into network compartments, is an important concept of Autonomic Networking.

Definition of Network Compartments 
Network Compartments implement the operational rules and administrative policies for a given communication context. The boundaries of a communication context, and hence the compartment boundaries, are based on technological and/or administrative boundaries. For example, compartment boundaries can be defined by a certain type of network technology (e.g., a specific wireless access network) or based on a particular communication protocol and/or addressing space (e.g., an IPv4 or and IPv6 network), but also based on a policy domain (e.g., a national health network that requires a highly secure boundary).

A compartment's communication principles, protocols and policies form a sort of “recipe” that all compartment entities must obey. For example, the recipe defines how to join a compartment, who can join, and how the naming, addressing and routing is handled. The complexity and details of the internal operation is left to each compartment. For example, registration with a compartment can range from complex trust-based mechanisms to simple registration schemes with a central database or a public DHT-based system; resolution of a communication peer can be handled implicitly by the compartment's naming and addressing scheme or require explicit actions (e.g., resolution of an identifier to a locator). It is important to note here that compartments have full autonomy on how to handle the compartment's internal communication – i.e. there are no global invariants that have to be implemented by all compartments or all communication elements.

Members of a compartment are able and willing to communicate among each other according to compartment's operational and policy rules. Conceptually a compartment maintains some form of implicit database which contains its members; that is, each entry in the database defines a member. Before one can send a data packet to a compartment member, a resolution step is required which returns a means to “address” the member. Note that the above definition does not specify whether a member is a node, a set of servers or a software module. This rather abstract definition of compartment membership permits to capture many different flavours of members and communication forms.

It is anticipated that many compartments co-exist and that compartments are able to interwork on various levels (e.g. through "layering" or "peering" of compartments).

Antarafacial and suprafacial. In organic chemistry, antarafacial (Woodward-Hoffmann symbol a) and suprafacial (s) are two topological concepts in organic chemistry describing the relationship between two simultaneous chemical bond making and/or breaking processes in or around a reaction center. The reaction center can be a p- or spn-orbital (Woodward-Hoffmann symbol ω), a conjugated system (π) or even a sigma bond (σ).
 The relationship is antarafacial when opposite faces of the π system or isolated orbital are involved in the process (think anti).  For a σ bond, it corresponds to involvement of one "interior" lobe and one "exterior" lobe of the bond.
 The relationship is suprafacial when the same face of the π system or isolated orbital are involved in the process (think syn). For a σ bond, it corresponds to involvement of two "interior" lobes or two "exterior" lobes of the bond.

The components of all pericyclic reactions, including sigmatropic reactions and cycloadditions, and electrocyclizations, can be classified as either suprafacial or antarafacial, and this determines the stereochemistry. In particular, antarafacial topology corresponds to inversion of configuration for the carbon atom of a [1, n]-sigmatropic rearrangement, and conrotation for electrocyclic ring closure, while suprafacial corresponds to retention and disrotation.

An example is the [1,3]-hydride shift, in which the interacting frontier orbitals are the allyl free radical and the hydrogen 1s orbitals. The suprafacial shift is symmetry-forbidden because orbitals with opposite algebraic signs overlap. The symmetry allowed antarafacial shift would require a strained transition state and is also unlikely. In contrast a symmetry allowed and suprafacial [1,5]-hydride shift is a common event.

Stereochemistry
Sendust. Sendust is a magnetic metal powder that was invented by Hakaru Masumoto at Tohoku Imperial University in Sendai, Japan circa 1936 as an alternative to permalloy in inductor applications for telephone networks.  Sendust composition is typically 85% iron, 9% silicon and 6% aluminium. The powder is sintered into cores to manufacture inductors. Sendust cores have high magnetic permeability (up to 140 000), low loss, low coercivity (5 A/m) good temperature stability and saturation flux density up to .

Due to its chemical composition and crystallographic structure Sendust exhibits simultaneously zero magnetostriction and zero magnetocrystalline anisotropy constant K1.

Sendust is harder than permalloy, and is thus useful in abrasive wear applications such as magnetic recording heads.

Graeme Haldane. Thomas Graeme Nelson Haldane, known as Graeme Haldane (14 December 1897 – 24 June 1981), was a Scottish engineer.

He was the son of Sir William Haldane and his wife Edith Nelson.  He was a nephew of Elizabeth Haldane, Richard Burdon Haldane, 1st Viscount Haldane and John Scott Haldane, and a cousin of the writer Naomi Mitchison.

He was educated at Royal Naval College, Osborne and Royal Naval College, Dartmouth and in the First World War served in the Royal Navy on HM Ships Doris Valiant and Tiger. He was present at the Battle of Jutland.

In 1919 he went to Trinity College, Cambridge and worked at the Cavendish Laboratory under Rutherford.  He helped establish the National Grid.

In 1928 he joined Merz and McLellan engineering firm, and in 1941 became a partner. In the summer of 1932 he was a member of a Fabian Society group which visited the Soviet Union, where he studied power stations and energy supply. In the following year he contributed the chapter on "Power and Industrial Developments" to a book entitled Twelve Studies in Soviet Russia edited by Margaret Cole. In 1948 he was President of the Institution of Electrical Engineers and won its James Watt Gold Medal in 1953.  He retired in 1972.

He had a son named Richard W. Haldane.

Honours
In 2021 he was inducted into the Scottish Engineering Hall of Fame.

Daniel and Florence Guggenheim Foundation. The Daniel and Florence Guggenheim Foundation is located at 950 Third Avenue in Manhattan.
New York, NY 10022.

History
The Daniel and Florence Guggenheim Foundation was founded in 1924 by Florence (née Shloss) and Daniel Guggenheim.

Between 1930 and 1941 the foundation financed Robert H. Goddard. When the United States government settled a patent lawsuit for infringing the Goddard patent for liquid fuel rockets, that money was awarded to the foundation.

The foundation was terminated on June 30, 2011. The Daniel and Florence Guggenheim Foundation Program on Demography, Technology and Criminal Justice has taken over some of the functions.

Swedish Electricians' Union. The Swedish Electricians' Union (, SEF), also called Elektrikerna, is a trade union representing electricians in Sweden.

The union was founded in Stockholm in 1906, following a split from the Swedish Metalworkers' Union. It initially had only 356 members, and this figure fluctuated until 1927, when it affiliated to the Swedish Trade Union Confederation.  Membership then grew to a peak of 29,170 in 1991, but has since been on a downward trajectory. The members numbered 24,775 in 2011 and 18,770 in 2019.

The union represents electricians in light and heavy instillations, as well as radio, TV and electronics technicians and power station staff.

Gryphon (parachute system). The Gryphon is a military wingpack that currently allows paratroopers to exit an aircraft at an altitude of 10 kilometres, then fly 40 kilometres while carrying up to 100 pounds of equipment. The system is still in development and the goal, according to Elektroniksystem- und Logistik-GmbH (Electronic System and Logistics Group or ESG), is to allow paratroopers to fly up to 200 kilometres per hour, thus enabling them to penetrate enemy airspace without compromising the safety of the aircraft or being detected by radar.
