The conditions of the Southern Sudanese Women Migrants in Abu Siid Shanty Town,Omdurman, Sudan — A Case Study of Cultural Change     

Fouad N. Ibrahim Dr. 《GeoJournal》1990,20(3):249-258

The author analyzes the changing conditions to which S Sudanese women have been subjected after their forced migration the war-ridden South to Khartoum. There, too, they are suffering from hunger, homelessness, lack of a basic needs. Being obliged to house and work illegally these women find themselves considered criminals by both the State and many of the so-called Arabs. Serious identity change is involved in the process of adaptationof these rural people to the hostile urban environment.This paper contains preliminary results of a field study conducted by the author in April 1989 within the framework of the research programme Identity in Africa of the German Research Society under the coordination of Helmut Ruppert and the author. Both, as well as Abdel Hamid Bakhit and Ismail Al Fihail have participated in this research on the migration of the Southerners to Khartoum.  相似文献

Characterization, classification, and determination of drinkability of some Algerian thermal waters     

Fouad Bahri  Hakim Saibi  Mohammed-El-Hocine Cherchali 《Arabian Journal of Geosciences》2011,4(1-2):207-219

In this study, the physicochemical parameters (Conductivity, pH, Cl^?, HCO ₃ ^? , PO ₄ ^3? , SO ₄ ^2? , NO ₃ ^? , NO ₂ ^? , F^?, TH, Ca²⁺, K⁺, Mg²⁺, Na⁺, and DS) were determined for 41 samples collected from fourteen places in Algeria. The temperature of the thermal water samples at collection sites varied from 26°C to 86°C. pH values varied from 6.5 to 8.5 (i.e., from slightly acidic to moderately alkaline); 90.24% of the samples exhibited relatively high salinity (DS?=?550–5,500 mg L^?1). Total hardness measurements indicated these waters to be moderately hard. Forty-six percent of the samples are Na–Cl in character. The ratios Na⁺/Ca²⁺, Na⁺/Mg²⁺, and (Na⁺ + K⁺)/(Ca²⁺ + Mg²⁺) were high in 90.24% of the samples. This indicates the ion exchange process is important, which indicates that most of the Algerian thermal waters had developed over a long period at a depth sufficient to react with the rock. Statistical analyses of the physicochemical data gave positive correlation values, thereby enabling good interpretation of the results and revealing the composition of ions present in the thermal waters, as well as some information about their origin. The therapeutic properties associated with thermal waters encourage people at spas to drink the water they bathe in. Therefore, we examined the drinkability of these thermal waters. World Health Organization (WHO 1993) standards were used to evaluate the thermal water quality for drinking. With respect to hardness, the samples were classified as moderately hard (58.54% of the samples), very hard (36.58% of the samples), and soft (4.88% of the samples). The drinkability study shows that only 16 samples of the investigated waters were drinkable and thus could be consumed without special precaution.  相似文献

Cultural change and the chances of reintegration after remigration to home areas — the case of the southern Sudanese dislocated population in Greater Khartoum     

Fouad N. Ibrahim 《GeoJournal》1995,36(1):103-107

About three million indigenous southern Sudanese have been dislocated as a result of the civil war which has been going on since 1955, with an interruption of only eleven years. The 1.5 million dislocated southern Sudanese in Khartoum are currently suffering from hunger and religious, social, political and economic discrimination. This paper argues, however, that a considerable number of them would prefer to keep living in the North, when the civil war comes to an end. After many years of separation from the South, it will be difficult, especially for those who came as young children to Khartoum, to reintegrate into the completely different environment of a war-wrecked South.  相似文献   

Use of two-dimensional electric resistivity and ground penetrating radar for archaeological prospecting at the ancient capital of Egypt     

Fouad F Shaaban  Fathy A Shaaban   《Journal of African Earth Sciences》2001,33(3-4)

Two-dimensional (2-D) resistivity and ground penetrating radar (GPR) surveys facilitate tracing of buried archaeological relics at the archaeological site of the Tell El Rabi'a, southwestern Cairo. These surveys also provide information on variations in depth of the groundwater table, which affect both exhumed and buried archaeological remains. The 2-D electrical resistivity profiles obtained show some high anomalies (up to 6900 Ω m). Based upon on-site calibration at partly exhumed sites, such anomalies are interpreted as pillar crowns and wall-like structures of hard limestone of the Hathour temple. The low background resistivities are interpreted to represent riverine deposits with differing moisture (or saturation) characteristics. The results of the GPR survey show three forms of high-amplitude radar anomalies, denoted as “P, H and R”. The “P” anomalies have semi-hyperbolic shapes, which suggest the presence of thin buried walls. The second, near-horizontal group of anomalies, “H”, may be either due to the presence of thick buried walls or arise from coincidental parallel alignment of survey lines with buried linear structures. The third group of GPR anomalies “R” is composed of chaotic reflections, and interpreted to depict buried stone-filled chambers. Some un-exhumed parts of the study area show weak radar reflections with occasional highly attenuated radar signals. These phenomena are ascribed to differing compaction and moisture characteristics of riverine soil layers. Recommendations with regard to archaeological site-excavation, preservation of archaeological relics, and soil conservation are submitted.  相似文献

Recharge,upflux and water table response for shallow water table conditions in southwest Florida     

Fouad H. Jaber  Sanjay Shukla  Saurabh Srivastava 《水文研究》2006,20(9):1895-1907

A disproportionate increase or decrease in water table in response to minor water input or drainage is observed in shallow water table conditions inside drainage lysimeters. This increase happens because the capillary fringe of the shallow water table reaches up to or near the surface (Wieringermeer effect). The correlations between water table level changes and rainfall, seepage irrigation, drip irrigation, and drainage were analysed. Correlations with rainfall, seepage irrigation, and drainage were high (R² ranged from 0·46 to 0·97). Drip irrigation had low correlations due to the low rates of application (R² ranged from 0·26 to 0·44). Conventional methods of calculating recharge, such as multiplying the specific yield with the water table fluctuations, cannot be used for Wieringermeer effect situations. A method using water balance data and soil moisture at different depths in the lysimeters was developed to estimate recharge and upflux. The recharge results were used to develop the apparent specific yield S_ya, which could be used to calculate consequent recharge events from water table fluctuation data. Combining the water table fluctuation relationships developed with the S_ya value will allow the prediction of recharge from rainfall and irrigation events without the need for soil moisture equipment.
