Date (phoenix dactylifera L)

A single bunch of date palms that weighs about 8 kg may contain as many as 1000 dates. “The dried fruit is more than 50% sugar by weight and contains about 2% each of protein, fat and mineral water” (online-family-doctor.com, n.d.).
Date palm belongs to the Phoenix dactylifera tree in the palm family. The mt genome of P. dactylifera shows a variety of unique traits as it happens to be the first of the family plants of palm. It not only positions at the known monocot mt genomes’ roots, but also has a significantly low repeat content level while it exhibits the RNA editing events in abundance. Date palm shows “a high level of chloroplast sequence insertions as compared to other known angiosperm mt genomes” (Fang et al., 2012, p. 9).
There is no objective record of the exact location where and time when the date palm originated as this information is believed to have been lost in antiquity, yet there are many records that suggest the cultivation of date palm in 4000 B.C. as the date palm was employed in the construction of the moon god’s temple in the Southern Iraq, Mesopotamia. Another proof of the antiquity of this fruit is the Nile Valley in Egypt where the date palm was adopted to symbolize a year in the Egyptian hieroglyphics whereas the frond of the date palm was used as a month’s symbol. “[This information] is confirmed by history, and corroborated by the archaeological research into ancient historical remains of the Sumerians, Akadians and Babylonians…Houses of these very ancient people were roofed with palm tree trunks and fronds. The uses of date for medicinal purposes, in addition to its food value, were also documented” (Zaid and Wet, n.d.). Date palms are believed to originate in Babel, Iraq, though there are also evidences of its origination in Harqan, and Dareen.
Date is one of the most nutritious and delicious fruits that have been ...

It has black markings on its face and legs and is of the size of a deer. It has reasonably long legs with wide hooves that help them in running in deserts. It possesses a splendid peripheral vision that helps it in spotting predators. It has the ability to increase its body temperature and make it higher than the ambient air in order to lose inordinate body heat (Walther, 1990). Although, sweating also helps the animal in loosing heat. The ability to increase its body temperature permits the Arabian Oryx to release heat into the surroundings. The brain is, however, protected during the process...

It was found from the comparison that the on average the northern population of Crotalus atrox has much greater heterozygosity than the southern population. Thus it can be considered that the northern population has more genetic variation than the southern population. Various reasons can be accounted for this genetic variation such as mutation in migration because of changed habitat, inbreeding within the southern population, as well as the genetic mechanisms such as genetic drift and gene flow bringing in forces like founder effect and population bottleneck. Therefore it can be concluded that...

The resin has a linker of acid sensitivity that allows the protection of dipeptide. Besides, the cleavage process also affects the selection of the resin. The synthesis process involved adopting the SPPS protocol which involves the use of DMF, resin, reagents like 4-Dimethylamionpyridine (DMAP) and DMF before the addition of liquid reagent (DIC). The resins were washed with DCM3, IPO 3 and NMP 3 several times. The cleavage process involves using a dilute TFA process. The dry resin was placed in the glass funnel and 1% 10 ml FTA of the dry DCM added, filtered through the application of nitrogen...
