Problem: At the very end of the 19th century, a new style, with a carved top and back construction inspired by violin family instruments began to supplant the European-style bowl-back instruments in the United States. This new style is credited to mandolins designed and built by Orville Gibson, a Kalamazoo, Michigan luthier who founded the "Gibson Mandolin-Guitar Manufacturing Co., Limited" in 1902. Gibson mandolins evolved into two basic styles: the Florentine or F-style, which has a decorative scroll near the neck, two points on the lower body and usually a scroll carved into the headstock; and the A-style, which is pear shaped, has no points and usually has a simpler headstock.

Problem: Infrared vibrational spectroscopy (see also near-infrared spectroscopy) is a technique that can be used to identify molecules by analysis of their constituent bonds. Each chemical bond in a molecule vibrates at a frequency characteristic of that bond. A group of atoms in a molecule (e.g., CH2) may have multiple modes of oscillation caused by the stretching and bending motions of the group as a whole. If an oscillation leads to a change in dipole in the molecule then it will absorb a photon that has the same frequency. The vibrational frequencies of most molecules correspond to the frequencies of infrared light. Typically, the technique is used to study organic compounds using light radiation from 4000400 cm1, the mid-infrared. A spectrum of all the frequencies of absorption in a sample is recorded. This can be used to gain information about the sample composition in terms of chemical groups present and also its purity (for example, a wet sample will show a broad O-H absorption around 3200 cm1).

Problem: In 2014, Turkey was ordered by the European Court of Human Rights to pay well over $100m in compensation to Cyprus for the invasion; Ankara announced that it would ignore the judgment. In 2014, a group of Cypriot refugees and a European parliamentarian, later joined by the Cypriot government, filed a complaint to the International Court of Justice, accusing Turkey of violating the Geneva Conventions by directly or indirectly transferring its civilian population into occupied territory. Over the preceding ten years, civilian transfer by Turkey had "reached new heights", in the words of one US ambassador.[f] Other violations of the Geneva and the Hague Conventionsboth ratified by Turkeyamount to what archaeologist Sophocles Hadjisavvas called "the organized destruction of Greek and Christian heritage in the north". These violations include looting of cultural treasures, deliberate destruction of churches, neglect of works of art, and altering the names of important historical sites, which was condemned by the International Council on Monuments and Sites. Hadjisavvas has asserted that these actions are motivated by a Turkish policy of erasing the Greek presence in Northern Cyprus within a framework of ethnic cleansing, as well as by greed and profit-seeking on the part of the individuals involved.
