The BEL20 is the benchmark stock market index of Euronext Brussels. In general, the index consists of a minimum of 10 and a maximum of 20 companies traded at the Brussels Stock Exchange. Since 20 June 2011, the BEL20 has contained 20 listings.
The composition of the BEL20 index is reviewed annually based on closing prices at the end of the calendar year. These changes are effected on the first trading day of every March. In addition to meeting a set of criteria demanding a company be "representative of the Belgian equity market", at least 15% of its shares must be considered free float in order to qualify for the index. In addition, a candidate for inclusion must possess a free float market capitalisation (in Euros) of at least 300000 times the price of the index on the last trading day of December. The minimum requirement for an existing constituent to remain in the index is a market cap of 200000 times the index value. At each annual review, the weights of companies in the index are capped at 15%, but range freely with share price subsequently. The BEL20 is a capitalization-weighted index.
Film (Persian:فیلم) is an Iranian film review magazine published for more than 30 years. The head-editor is Massoud Mehrabi.
In fluid dynamics, lubrication theory describes the flow of fluids (liquids or gases) in a geometry in which one dimension is significantly smaller than the others. An example is the flow above air hockey tables, where the thickness of the air layer beneath the puck is much smaller than the dimensions of the puck itself.
Internal flows are those where the fluid is fully bounded. Internal flow lubrication theory has many industrial applications because of its role in the design of fluid bearings. Here a key goal of lubrication theory is to determine the pressure distribution in the fluid volume, and hence the forces on the bearing components. The working fluid in this case is often termed a lubricant.
Free film lubrication theory is concerned with the case in which one of the surfaces containing the fluid is a free surface. In that case the position of the free surface is itself unknown, and one goal of lubrication theory is then to determine this. Surface tension may then be significant, or even dominant. Issues of wetting and dewetting then arise. For very thin films (thickness less than one micrometre), additional intermolecular forces, such as Van der Waals forces or disjoining forces, may become significant.
Film periodicals combine discussion of individual films, genres and directors with in-depth considerations of the medium and the conditions of its production and reception. Their articles contrast with film reviewing in newspapers and magazines which principally serve as a consumer guide to movies.
