Cyclone and Tsunami Hazards in the Arabian Sea-A Numerical Modelling Case Study by Royal HaskoningDHV

Significant loss of life and damage to properties, ecosystems and marine facilities occur due to various natural hazards such as cyclones and tsunamis. Royal HaskoningDHV has developed regional hydrodynamic and wave models covering the Northern Arabian Sea to address these issues. Cyclone modelling was carried out on 11 major cyclones since 1945 and the tsunami modelling on an earthquake along the Makran Fault Line in 1945. Sample results from these modelling studies are presented in this paper. The methodology described in this article for modelling cyclones and tsunamis in the Arabian Sea could be applied to simulate these natural hazards at other sites around the world.

Physico-Chemical Analysis of Korapuzha River and Estuaries

Korapuzha is a short river of 40 km with a drainage area of 624 km^2, flowing from dense forest and empties into the Arabian sea. It is formed by the confluence of two streams Agalapuzha and Punnoorpuzha. In this study the samples were collected from Agalapuzha, Punnoorpuzha and Korappuzha, Korapuzha estuaries. The temperature and pH were monitored on the site and the remaining parameters were analyzed in the laboratory. The physical quality parameters such as color, odor, appearance and chemical quality parameters such as pH, alkalinity, chloride, nitrate, nitrite, sulphate, ammonia, dissolved oxygen, total solids, total hardness, and iron have been evaluated. Compare the physical and chemical parameters. The physico-chemical analysis shows that the samples have high level of salinity, sulphate, total solids and total hardness. The results show that the water is affected by the intrusion of sea water into the river by excess excavation of sands from river for the construction of buildings and other anthropogenic activities which leads to environmental destruction.

Relationship between Numbers and Letters

This paper proposes that there is a relation between numbers and letters. This relation may exist in all types of different languages. This research focuses on the reason of choosing some mathematical symbols like ＂ ＂ and ＂π＂ in Arabic, Latin, and English languages. Also, this paper presents some relations between months, weeks, and days in Arabic, English, and Latin languages.

Israel＇s Changing Attitude Toward the Arab National Minority： Between Ben Gurion and Eshkol Military Rule as a Test Case

In August 1963, Israel＇s Prime Minister Levi Eshkol initiated the procedure for terminating the martial law in effect since the end of the War of Independence （1948） with regard to Israeli Arabs. Martial law discriminated against Israel＇s Arab minority, as opposed to the majority of Israel＇s society, as part of different issues bound up with this population＇s daily functioning. The aim of the paper is to present the reasons why Eshkol＇s doing away with the martial law stemmed was its ineffectiveness, while the other, and this makes up the core of our concern here, was his changing attitude toward the Arab minority in Israel, by contrast with that of his predecessor, David Ben Gurion The main conclusion of the paper is that even though Eshkol＇s ideas about the Arab minority were not very different from Ben Gurion＇s ideas one insisted on maintaining the military government in Israel, while the other saw this as unnecessary, and so brought it to an end. In August 1963, a few months after assuming office, Israel＇s Prime Minister Levi Eshkol initiated the first steps leading to the annulment of military rulet which had applied to Arabs in the State of Israel ever since the end of the War of Independence （1948）. This process was concluded some three years later. Military rule was lifted in effect on December 1, 1966. In the presentation, the author would like to look into the considerations which prompted Eshkol to take such a step, in light of the fact that his predecessor, Ben Gurion, was a staunch opponent of annulling the military regime, convinced as he was, even after the conclusion of his term in office, that the current state of affairs should remain in effect.

Ecological Study on Bacteria-Zooplankton Interaction in Domat AI-Gandal Lake, AL-Jouf Area, Kingdom of Saudi Arabia

A year-long survey of some physical parameters （water temperature, dissolved oxygen, pH, turbidity）, chemical parameters （Biological Oxygen Demand ＂BOD＂, Chemical Oxygen Demand ＂COD＂, nitrate, ammonia, orthophosphate） and some biological （zooplankton） and microbiological （total bacteria, indicator bacteria, pathogenic bacteria） components in Domat AI-Gandal Lake was conducted. Water samples were collected seasonally from spring 2004 to winter 2005. Four locations on the Lake were sampled in order to evaluate the condition of the Lake. To investigate the possible effect of zooplankton in controlling the presence of faecal indicator bacteria, a 24 hour experiment was carried out to examine this hypothesis as well as the grazing pressure of zooplankton on the bacterial community of the Lake. The results showed that variations in season temperature affected the zooplankton and density of bacteria in the Lake. Zooplankton was composed by Protozoa 75%, Rotifera 20.6%, Cladocera 3% and Copepoda 2%. The reduction rates for the tested faecal pollution indicators in presence of zooplankton predators were remarkable （up to 99%）. In conclusion zooplankton, especially protozoa, was found to play an important role as biological control against bacterial indicators of faecal pollution.

Heritage of Arabic Language in South Caucasus： Arabic Inscriptions From Trialeti

In this article the author would like to discuss the usage of Arabic language in South Georgia as language of religious and ethnical minority in circumstances of Russian rule. The best examples of this are Arabic inscriptions on gravestones. In this article the author describes several inscriptions from Trialeri, South Georgia, which, because of unknown reasons, have never been studied by scientists before. Another important reason why the author has paid importance to those inscriptions is their recent condition and danger to lose them forever. The author has studied inscriptions from three main cemeteries： Beshtasheni, Tikma-Dash, and Minayasar. As a result of his research the author can say that Arabic language have been used by Muslims of Turk origins in Trialeti till Soviet time. They were using this language to preserve their identity, but it used to work only about a century. Soviet rule tried to destroy all identities and religions and especially after WWII they have reached more or less success. Today the Muslim population of Trialtei does not understand Arabic, they just know that their religion is Islam and in the graves with Arabic inscriptions lay their predecessors.
