Nahr (toponymy)
The glossary of Arabic toponyms gives translations of Arabic terms commonly found as components in Arabic toponyms. A significant number of them were put together during the PEF Survey of Palestine carried out in the second half of the 19th century.

Al-Nahr
al-Nahr ( ar, النهر), was a Palestinian village northeast of Acre. It was depopulated in May 1948 after a military assault carried out by the Carmeli Brigade as part of the Israel Defense Forces's Operation Ben-Ami. Immediately after the assault, the village of al-Nahr was razed.Benvenisti, 2000, pp138-139/ref> History The twin villages of al-Nahr and nearby al-Tall were both sites of ancient settlements atop the tel of Kabri. Recent excavations indicate habitation back to the sixth millennium BC.Stern, Lewinson-Gilboa and Avriam, 1993, pp. 839–841 Ottoman era In the Ottoman period, the village appeared under the name of ''El Qahweh'' in Pierre Jacotin´s map from 1799. In 1875, the French explorer Victor Guérin visited the village, which he called ''El Kahoueh''. He found it to have 120 inhabitants, all Muslims. In 1881 the PEF's ''Survey of Western Palestine'' described the village, then named ''El Kahweh'', as a "stone village, containing about 250 Moslems, [] ...

Non-allelic Homologous Recombination
Non-allelic homologous recombination (NAHR) is a form of homologous recombination that occurs between two lengths of DNA that have high sequence similarity, but are not alleles. It usually occurs between sequences of DNA that have been previously duplicated through evolution, and therefore have low copy repeats (LCRs). These repeat elements typically range from 10–300 kb in length and share 95-97% sequence identity. During meiosis, LCRs can misalign and subsequent crossing-over can result in genetic rearrangement. When non-allelic homologous recombination occurs between different LCRs, deletions or further duplications of the DNA can occur. This can give rise to rare genetic disorders, caused by the loss or increased copy number of genes within the deleted or duplicated region. It can also contribute to the copy number variation seen in some gene clusters. As LCRs are often found in "hotspots" in the human genome, some chromosomal regions are particularly prone to NAHR.
