Ball possession: Ball possession is the amount of time a team possesses the ball during a game of football.  Possession is usually expressed as a percentage (for example, 60% for team A, 40% for team B).  Historically, Dutch clubs (especially Ajax) were famous for dominating ball possession, but more recently Barcelona of La Liga became the best in maintaining ball possession; Germany's Bayern Munich came out second.  However, after the arrival of Pep Guardiola at Bayern Munich, the team is considered to dominate possession more than Barcelona, which they did during the semi-final of the 2014–15 UEFA Champions League.  Xavi is considered to be the most possessive player in recent years.  Paul Scholes of Manchester United and England, was also very famous for his passing skills and the ability to dominate ball possession.  Teams that play possession football often try to press their opponents high in the pitch, so to recover the ball rapidly.  As a result, the defensive line of team that play possession football is usually place very high in the pitch, around the halfway line and not unusually, in the opponents half.  When the team loses the ball the defensive line must move rapidly otherwise the team may be subject to dangerous counter-attacks because of their high defensive line.

Narlıdere: Narlıdere is a district of İzmir Province in Turkey.  It is one of the nine districts in the Greater Metropolitan Area of İzmir, one of the smallest in terms both of population and area, and is fully (100.0%) urbanized.  The district center has no depending township with own municipalities or villages.  Narlıdere district area follows the southern coastline of the inner Gulf of İzmir.  Narlıdere center is at a distance of 10 km to the west from the traditional center of İzmir (Konak).  Narlıdere district area neighbors the district areas of Balçova to the east, Menderes (Cumaovası) to the south and Güzelbahçe to the west, this last also being westernmost among İzmir's metropolitan districts.  Narlıdere district's overall levels of education are among the highest in Turkey, the literacy rate reaching 93 per cent, while the calculations for average yearly income per inhabitant situate Narlıdere rather below the national average, at 2.393 US Dollars, for which its open approach to outside immigration may have played a role.  The overall appearance of Narlıdere leaves the impression of a locality where people are generally educated and who subsist on mid- to low-level revenues without being destitute.  Narlıdere was founded as a village by semi-nomadic Tahtacı–Alevi Turkmens in the 18th century, whose descendants still constitute the backbone of the population, preserving their particular popular culture and folklore, and maintaining their recently restored seminary, called Cemevi.  The name the district has made as such contributes to its status as pole of attraction for various specific parts of the population in Turkey (its population is projected to have increased from 54.107 to 66.446 between 2000-2006).  The economy is still largely based on agriculture (especially citrus fruit and flowers), although new housing projects putting Narlıdere's advantageous location to benefit and generally aimed at high-income residents started to be built in recent years, and there is a five-star hotel.  As such, Narlıdere became in recent years one of İzmir's metropolitan districts where the economy grew the fastest.

Industrial enzymes: Industrial enzymes are enzymes that are commercially used in a variety of industries such as pharmaceuticals, chemical production, biofuels, food & beverage, and consumer products.  Due to advancements in recent years, biocatalysis through isolated enzymes is considered more economical than use of whole cells.  Enzymes may be used as a unit operation within a process to generate a desired product, or may be the product of interest.  Industrial biological catalysis through enzymes has experienced rapid growth in recent years due to their ability to operate at mild conditions, and exceptional chiral and positional specificity, things that traditional chemical processes lack.  Isolated enzymes are typically used in hydrolytic and isomerization reactions.  Whole cells are typically used when a reaction requires a co-factor.  Although co-factors may be generated in vitro, it is typically more cost-effective to use metabolically active cells.
