Jalo Oasis
Jalo Oasis (or Jalu, or Gialo) is an oasis in Cyrenaica, Libya, located west of the Great Sand Sea and about 250 km south-east of the Gulf of Sidra. Quite large, long and up to wide, it supports a number of settlements, the largest of which is the town of Jalu. Jalu was the administrative capital of the Jalu District from 1983 to 1988, at which time the area became part of the Ajdabiya District and as of 2007 is now part of the Al Wahat District. Because of its location and as a source of water, it had strategic importance during the North African Campaign in World War II and changed hands several times between Allied and Axis forces. The water at the Jalo oasis is quite salty (3,880 parts per million).Walton, Kenneth (2007) ''The Arid Zones'' AldineTransaction, New Brunswick, New Jerseypage 109 ; originally published by Aldine Publishing Company, Chicago, in 1969, The water is an alkaline with a pH of 7.4 and is very hard with numerous dissolved salts in addition ...

Jalu
Jalu, Jallow, or Gialo ( ar, جالو) is a town in the Al Wahat District in northeastern Libya in the Jalo oasis. An oasis, a city, and it is the main center of the oasis region in eastern Libya. It is located at the confluence of longitude and latitude (21-29), and the most important characteristic of visitors and onlookers is the presence of dense palm forests linking the sand dunes and plateaus of the Libyan desert. Its inhabitants were famous for trade and transporting goods from Cyrenaica and Tripoli to (Chad, Egypt and Sudan) and other African countries. It is an ancient oasis mentioned by Arab travelers, and orientalists in many historical sources. Historical sources mention that the people of the Jallow oasis were the first to conduct trade caravans along the longest desert route from The Libyan coast to central and eastern Africa around the middle of the nineteenth century and the beginning of the twentieth century.

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, massa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sodium Chloride
Sodium chloride , commonly known as salt (although sea salt also contains other chemical salts), is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions. With molar masses of 22.99 and 35.45 g/mol respectively, 100 g of NaCl contains 39.34 g Na and 60.66 g Cl. Sodium chloride is the salt most responsible for the salinity of seawater and of the extracellular fluid of many multicellular organisms. In its edible form, salt (also known as '' table salt'') is commonly used as a condiment and food preservative. Large quantities of sodium chloride are used in many industrial processes, and it is a major source of sodium and chlorine compounds used as feedstocks for further chemical syntheses. Another major application of sodium chloride is de-icing of roadways in sub-freezing weather. Uses In addition to the familiar domestic uses of salt, more dominant applications of the approximately 250 million tonnes per year product ...

Alkalinity
Alkalinity (from ar, القلوي, al-qaly, lit=ashes of the saltwort) is the capacity of water to resist acidification. It should not be confused with basicity, which is an absolute measurement on the pH scale. Alkalinity is the strength of a buffer solution composed of weak acids and their conjugate bases. It is measured by titrating the solution with an acid such as HCl until its pH changes abruptly, or it reaches a known endpoint where that happens. Alkalinity is expressed in units of concentration, such as meq/L (milliequivalents per liter), μeq/kg (microequivalents per kilogram), or mg/L CaCO3 (milligrams per liter of calcium carbonate). Each of these measurements corresponds to an amount of acid added as a titrant. Although alkalinity is primarily a term used by oceanographers, it is also used by hydrologists to describe temporary hardness. Moreover, measuring alkalinity is important in determining a stream's ability to neutralize acidic pollution from rainfal ...

Salinity
Salinity () is the saltiness or amount of salt (chemistry), salt dissolved in a body of water, called saline water (see also soil salinity). It is usually measured in g/L or g/kg (grams of salt per liter/kilogram of water; the latter is dimensionless and equal to ‰). Salinity is an important factor in determining many aspects of the chemistry of natural waters and of biological processes within it, and is a state function, thermodynamic state variable that, along with temperature and pressure, governs physical characteristics like the density and heat capacity of the water. A contour line of constant salinity is called an ''isohaline'', or sometimes ''isohale''. Definitions Salinity in rivers, lakes, and the ocean is conceptually simple, but technically challenging to define and measure precisely. Conceptually the salinity is the quantity of dissolved salt content of the water. Salts are compounds like sodium chloride, magnesium sulfate, potassium nitrate, and sodium bicarbo ...

Oasis
In ecology, an oasis (; ) is a fertile area of a desert or semi-desert environment'ksar''with its surrounding feeding source, the palm grove, within a relational and circulatory nomadic system.” The location of oases has been of critical importance for trade and transportation routes in desert areas; caravans must travel via oases so that supplies of water and food can be replenished. Thus, political or military control of an oasis has in many cases meant control of trade on a particular route. For example, the oases of Awjila, Ghadames and Kufra, situated in modern-day Libya, have at various times been vital to both north–south and east–west Trans-Saharan trade, trade in the Sahara Desert. The location of oases also informed the Darb El Arba'īn trade route from Sudan to Egypt, as well as the caravan route from the Niger River to Tangier, Morocco. The Silk Road “traced its course from water hole to water hole, relying on oasis communities such as Turpan in China and Sa ...

Al Wahat District
Al Wahat or The Oases ( ar, الواحات ', en, The Oases), occasionally spelt ''Al Wahad'' or ''Al Wahah'' ( en, The Oasis) is one of the districts of Libya.''Statesman's Yearbook 2006'' Its capital and largest city is Ajdabiya. The district is home to much of Libya's petroleum extraction economic activity. History Traditionally Al Wahat was the western part of Cyrenaica. With the division of Libya into ten governorates in 1963, Al Wahat became part of the Misrata Governorate. In the 1973 reorganization it became part of Al Khalji Governorate. In 1983 Al Khalji was divided into a number of baladiyat (districts), with what is now Al Wahat being included in the Ajdabiya baladiyah and the Jalu baladiyah. In the 1988 reorganization, Jalu was subsumed within Ajdabiya baladiyah. The status of the area in the reorganization of 1995 which created thirteen districts is unclear; however, in the 1998 reorganization into twenty-six districts, the name "Al-Wahad" appears as a district ...
