Nicholas Aylward Vigors was an Irish zoologist and politician. He popularized the classification of birds on the basis of the quinarian system. Vigors was born at County Carlow, he studied at Trinity College, Oxford. He served in the army during the Peninsular War from 1809 to 1811, he returned to Oxford, graduating in 1815. He practiced as a barrister and became a Doctor of Civil Law in 1832. Vigors was a co-founder of the Zoological Society of London in 1826, its first secretary until 1833. In that year, he founded, he was a fellow of the Royal Society. He was the author of 40 papers on ornithology, he described 110 species of birds. He provided the text for John Gould's A Century of Birds from the Himalaya Mountains. One bird that he described was "Sabine's snipe"; this was treated as a common snipe by Barrett-Hamilton in 1895 and by Meinertzhagen in 1926, but was thought to be a Wilson's snipe in 1945. Vigors lent a skin for editions of Thomas Bewick's History of British Birds. Vigors succeeded to his father's estate in 1828.
He was MP for the borough of Carlow from 1832 until 1835. He represented the constituency of County Carlow in 1835. Vigors had been elected in a by-election in June after the Conservative MPs returned at the 1835 United Kingdom general election were unseated on petition and a new writ issued. On 19 August 1835 Vigors and his running mate, in the two member county constituency, were unseated on petition; the same two Conservatives, unseated were awarded the seats. On the death of one of them, Vigors won the subsequent by-election in 1837 and retained the seat until his own death. Webb, Alfred. "Vigors, Nicholas Aylward". A Compendium of Irish Biography.

In organic chemistry, enone–alkene cycloadditions are a version of the cycloaddition This reaction involves an enone and alkene as substrates. Although the concerted photochemical cycloaddition is allowed, the reaction between enones and alkenes is stepwise and involves discrete diradical intermediates. In 1908, it was reported. Subsequent investigations demonstrated the utility of the photochemical cycloaddition of enones to alkenes. In spite of the stepwise, radical mechanism, both stereoselective intra- and intermolecular variants have emerged. Cyclic enones are employed, otherwise competitive cis-trans isomerization ensues; the mechanism of photocyclization is proposed to begin with photoexcitation of the enone to a singlet excited state. The singlet state is very short lived, decays by intersystem crossing to the triplet state. At this point, the enone forms an exciplex with the ground state alkene giving the triplet diradical. Spin inversion to the singlet diradical allows closure to the cyclobutane.
As an alternative a pericyclic reaction mechanism is proposed, in which after intersystem crossing a radical cation and a radical anion are formed, which recombine to the cyclobutane. Enone–alkene cycloadditions can produce two isomers, depending on the orientation of substituents on the alkene and the enone carbonyl group; when the enone carbonyl and substituent of highest priority are proximal, the isomer is termed "head-to-head." When the enone carbonyl and substituent are distal, the isomer is called "head-to-tail." Selectivity for one of these isomers depends on both electronic factors. The regiochemistry of the reaction is controlled by two factors: steric interactions and electrostatic interactions between the excited enone and alkene. In their excited state, the polarity of enones is reversed so that the β carbon possesses a partial negative charge. In the transition state for the first bond formation, the alkene tends to align itself so that the negative end of its dipole points away from the β carbon of the enone.
Steric interactions encourage the placement of large substituents on opposite sides of the new cyclobutane ring. If the enone and alkene are contained in rings of five atoms or fewer, double-bond configuration is preserved. However, when larger rings are used, double bond isomerization during the reaction becomes a possibility; this energy-wasting process competes with cycloaddition and is evident in reactions that yield mixtures of cis- and trans-fused products. Diastereofacial selectivity is predictable in most cases; the less hindered faces of the enone and alkene react. Intramolecular enone–alkene cycloaddition may give either "bent" or "straight" products depending on the reaction regioselectivity; when the tether between the enone and alkene is two atoms long, bent products predominate due to the rapid formation of five-membered rings. Longer tethers tend to give straight products; the tether can be attached at the 2 position of the enone. When the alkene is tethered here, bulky substituents at the 4 position of the enone enforce moderate diastereoselectivity.
Enone–alkene cycloaddition has been applied to the synthesis of a cubane. The Favorskii rearrangement established the carbon skeleton of cubane, further synthetic manipulations provided the desired unfunctionalized target. Enone–alkene cycloadditions suffer from side reactions, e.g. those associated with the diradical intermediate. These side reactions can be minimized by a judicious choice of reaction conditions. Dissolved oxygen is avoided. A variety of solvents can be used. Acetone is a useful solvent. Alkane-based solvents are selected to be free of alkenes. Excitation wavelength is important. For intermolecular reactions, excess of the alkene can be employed to avoid competitive dimerization of the enone. Reverse photocycloaddition, decomposition of 1,2-dioxetanedione, is stated as the mechanism that produces light in glow sticks

The Piccadilly line extension to Cockfosters added eight new stations to the northern end of London Underground's Piccadilly line. The extension through north London from Finsbury Park to Cockfosters was opened in three stages between 19 September 1932 and 31 July 1933; when the Great Northern and Brompton Railway opened in December 1906, its northern terminus was at Finsbury Park where it had an interchange with the Great Northern Railway and the Great Northern & City Railway. To obtain approval for the railway's construction, the GNP&BR had, like the GN&CR before it, had to accept a GNR veto over further extensions north in competition with the latter's suburban passenger services from King's Cross. Soon after the GNP&BR opened it was clear that the termination of the line in urban Finsbury Park rather than further out of central London in more suburban Wood Green, Southgate or Tottenham had been a mistake. Passengers leaving the GNP&BR and the GN&CR at Finsbury Park preferred to transfer on to trams and buses for the continuation of their journeys, rather than use the GNR as it had hoped.
This caused much congestion in and around the station at Finsbury Park. Calls for a solution to the congestion at Finsbury Park were frequent from the GNP&BR's opening and after the First World War the campaign for extending the line gathered strength. In 1921, the Municipal Borough of Tottenham, sent a resolution to the Government, suggesting the desirability of extending one of the two lines terminating at Finsbury Park to Seven Sisters Corner. In the face of mounting pressure the London and North Eastern Railway continued the opposition of its predecessor, the GNR, to a northward extension of the Piccadilly line although it did begin developing plans for the electrification of its own suburban services; when the LNER cancelled the electrification of its routes due to lack of money, a petition from the Middlesex Federation of Ratepayers in 1923 spurred the government to act and, in 1925, "The North and North-East London Traffic Inquiry" was set up to examine options. When the Inquiry reported, it recommended an extension only one station to Manor House.
The LNER was placed in the position of either carrying out the electrification of its own services or withdrawing its veto to an extension of the Piccadilly line. To make the extension financially worthwhile, the Underground Group needed to maximise the number of passengers using it by extending the new route as far as possible to the north and by building as much of it as possible on the surface for which construction is cheaper than in tunnel. A route was proposed out to rural Oakwood and Cockfosters although the Underground Group did not have the money to construct the limited extension to Manor House; the recession of the late 1920s provided the economic imperative for the construction of the extension. The government introduced the Development Act in 1930 which provided government guarantees on loans raised for construction; the aim was to increase employment through a stimulation of public works projects and, with guarantees available on the money needed for the construction, the Underground Group was able to start work on the Cockfosters extension, the Piccadilly line western extension as well as many other projects throughout the Underground network.
All the stations were designed by Charles Holden and colleagues in a modern European style, assembling the buildings from a collection of basic geometric shapes. Despite the Underground Group's wish to construct most of the extension on the surface, the first four stations are underground; the line surfaces at Arnos Grove before going back into tunnel to pass through a hill at Southgate. North of Southgate, the line is on the surface for the rest of the route to Cockfosters, thus five of the eight stations on the extension are underground. The extension passes directly underneath Harringay Green Lanes railway station, but no provision for an interchange was made since at the time the Tottenham and Hampstead Junction Railway it lay on was a freight line with few passenger services. Earlier versions of the extension had included a station to the north at St Ann's Road, but this was dropped from plans as the growing tramway network in the area was considered adequate. Opened on 19 September 1932Manor House Harringay, proposed in 1902 plans but omitted from the plans Turnpike Lane, other proposed names.
