Florey and Chain succeeded in purifying the first penicillin, penicillin G, in 1942, but it did not become widely available outside the Allied military before 1945. Later, Norman Heatley developed the back extraction technique for efficiently purifying penicillin in bulk. The chemical structure of penicillin was determined by Dorothy Crowfoot Hodgkin in 1945. Purified penicillin displayed potent antibacterial activity against a wide range of bacteria and had low toxicity in humans. Furthermore, its activity was not inhibited by biological constituents such as pus, unlike the synthetic sulfonamides. The discovery of such a powerful antibiotic was unprecedented, and the development of penicillin led to renewed interest in the search for antibiotic compounds with similar efficacy and safety. For their successful development of penicillin, which Fleming had accidentally discovered but could not develop himself, as a therapeutic drug, Ernst Chain and Howard Florey shared the 1945 Nobel Prize in Medicine with Fleming. Florey credited Dubos with pioneering the approach of deliberately and systematically searching for antibacterial compounds, which had led to the discovery of gramicidin and had revived Florey's research in penicillin.

Ah, so.. Norman Heatley

An exhibition game (also known as a friendly, a scrimmage, a demonstration, a preseason game, a warmup match, or a preparation match, depending at least in part on the sport) is a sporting event whose prize money and impact on the player's or the team's rankings is either zero or otherwise greatly reduced. In team sports, matches of this type are often used to help coaches and managers select players for the competitive matches of a league season or tournament. If the players usually play in different teams in other leagues, exhibition games offer an opportunity for the players to learn to work with each other. The games can be held between separate teams or between parts of the same team.

As a non-directive and flexible analytical tool, the concept of boundaries helps both to map and to define the changeability and mutability that are characteristic of people's experiences of the self in society. While identity is a volatile, flexible and abstract 'thing', its manifestations and the ways in which it is exercised are often open to view. Identity is made evident through the use of markers such as language, dress, behaviour and choice of space, whose effect depends on their recognition by other social beings. Markers help to create the boundaries that define similarities or differences between the marker wearer and the marker perceivers, their effectiveness depends on a shared understanding of their meaning. In a social context, misunderstandings can arise due to a misinterpretation of the significance of specific markers. Equally, an individual can use markers of identity to exert influence on other people without necessarily fulfilling all the criteria that an external observer might typically associate with such an abstract identity.
