Managers in the Premier League are involved in the day-to-day running of the team, including the training, team selection, and player acquisition. Their influence varies from club-to-club and is related to the ownership of the club and the relationship of the manager with fans. Managers are required to have a UEFA Pro Licence which is the final coaching qualification available, and follows the completion of the UEFA 'B' and 'A' Licences. The UEFA Pro Licence is required by every person who wishes to manage a club in the Premier League on a permanent basis (i.e. more than 12 weeks the amount of time an unqualified caretaker manager is allowed to take control). Caretaker appointments are managers that fill the gap between a managerial departure and a new appointment. Several caretaker managers have gone on to secure a permanent managerial post after performing well as a caretaker; examples include Paul Hart at Portsmouth and David Pleat at Tottenham Hotspur.

Ah, so.. UEFA Pro Licence

Arsenal began winning silverware again with the surprise appointment of club physiotherapist Bertie Mee as manager in 1966. After losing two League Cup finals, they won their first European trophy, the 196970 Inter-Cities Fairs Cup. This was followed by an even greater triumph: their first League and FA Cup double in 197071. This marked a premature high point of the decade; the Double-winning side was soon broken up and the following decade was characterised by a series of near misses, starting with Arsenal finishing as FA Cup runners up in 1972, and First Division runners-up in 197273.

Ah, so.. 197071

This reaction is favored at low pressures but is nonetheless conducted at high pressures (2.0 MPa, 20 atm or 600 inHg). This is because high-pressure H
2 is the most marketable product and Pressure Swing Adsorption (PSA) purification systems work better at higher pressures. The product mixture is known as "synthesis gas" because it is often used directly for the production of methanol and related compounds. Hydrocarbons other than methane can be used to produce synthesis gas with varying product ratios. One of the many complications to this highly optimized technology is the formation of coke or carbon:

Ah, so..
