Twin-Screw Granulation
Twin-screw granulation (TSG) is a pharmaceutical process that has gained increased interest from the pharmaceutical industry for its potential for the development of oral dosage forms. The technology has evolved rapidly due to the flexibility of the equipment design, the selection of the process variables and the wide range of processed materials. Most importantly, TSG offers the benefits of both batch and continuous manufacturing for pharmaceutical products, accompanied by excellent process control, high product quality which can be achieved through the implementation of Quality by Design (QbD) approaches and the integration of Process Analytical Tools (PAT).

List of Most Successful U-boat Commanders
The list of most successful U-boat commanders contains the top-scoring German U-boat commanders in the two World Wars based on their total tonnage sunk. The tonnage figures (and sometimes the number of ships sunk) is still being debated among historians. This is often due to convoy battles at night when an attacking "wolfpack" fired torpedoes into the convoy and two (sometimes more) commanders claimed the same ship. Although post-war research has clarified most of those claims, some are still in question.

Compounds of Fluorine
Fluorine forms a great variety of chemical compounds, within which it always adopts an oxidation state of −1. With other atoms, fluorine forms either polar covalent bonds or ionic bonds. Most frequently, covalent bonds involving fluorine atoms are single bonds, although at least two examples of a higher order bond exist. Fluoride may act as a bridging ligand between two metals in some complex molecules. Molecules containing fluorine may also exhibit hydrogen bonding (a weaker bridging link to certain nonmetals). Fluorine's chemistry includes inorganic compounds formed with hydrogen, metals, nonmetals, and even noble gases; as well as a diverse set of organic compounds. For many elements (but not all) the highest known oxidation state can be achieved in a fluoride. For some elements this is achieved exclusively in a fluoride, for others exclusively in an oxide; and for still others (elements in certain groups) the highest oxidation states of oxides and fluorides are always equal.

Alternating Direction Implicit Method
In numerical linear algebra, the Alternating Direction Implicit (ADI) method is an iterative method used to solve Sylvester matrix equations. It is a popular method for solving the large matrix equations that arise in systems theory and control, and can be formulated to construct solutions in a memory-efficient, factored form. It is also used to numerically solve parabolic and elliptic partial differential equations, and is a classic method used for modeling heat conduction and solving the diffusion equation in two or more dimensions. It is an example of an operator splitting method.

Lingua Franca
A lingua franca is any language widely used beyond the population of its native speakers. The de facto status of lingua franca is usually "awarded" by the masses to the language of the most influential nation(s) of the time. Any given language normally becomes a lingua franca primarily by being used for international commerce, but can be accepted in other cultural exchanges, especially diplomacy. Occasionally the term "lingua franca" is applied to a fully established formal language; thus formerly it was said that French was the lingua franca of diplomacy. The term "lingua franca" was originally used by Arabs to name all Romance languages, and especially Italian (Arabs used the name 'Franks' for all peoples in Western Europe). Then, it meant a language with a Romance lexicon (most words derived from Latin which then evolved into early forms of Spanish and Italian) and a very simple grammar, that till the end of the 19th century was used by mariners in the Mediterranean Sea, particularly in the Middle East and Northern Africa. A related concept is that of a “vehicular language.” It is defined as a basic linguistic structure for proposed “international auxiliary languages,” for example, the use of an Indo-European language, or Indo-European itself, in the development of Esperanto.
