“…He also found that total Ni content in the surface layer of soil irrigated with waste drain containing 27-112 ppm, and extractable Ni from 0.02 to 1.76 ppm. Similar results were recorded by El-Saady (1994) andRashad (1986) Hassan (1997). studied the effect of using different industrial wastewater for irrigating some soils in Shoubra El-Khiema.…”

In this study Ni species were determined using a sequential extraction technique. The method consists of sequential extraction of the soil with different solutions, and it is designed to separate into six operationally defined fractions namely water soluble, exchangeable, carbonate bound, Fe-Mn oxides bound, organic bound and residual fractions. The objectives of this study were to investigate nickel forms in tested soils and to determine the effect of industrial wastewater effluent irrigation on the metal fractions in soil. Data showed a remarkable increase in all tested Ni-forms in polluted soil. It could be concluded that soil composition has been changed with depth. Especially under such condition whereas, metal soluble organic compounds found in wastewater may precipitate and percolates through soil and may transport soluble Ni with the soil solution.

“…The images clarified the degree of deterioration and degradation of tunic, in addition to linen fibers as a main component. While the EDX analytical results, (4-c) showed that the Ca, Cl, Si, S, Mg and Al as traces elements are essentially attributed to the burial effects as attested by Antoniou, et al [22] Hassan, et al, and [23]. The study is also confirm that it is necessary to conserve the tunic in the museum, this processes that improved the appearance of the tunic through improving its physical and mechanical properties which will make it more durable.…”

“…The dirt consists of calcium, chlorine, silicon, sulphide, magnesium and aluminum. These elements cause damage to fibers if accumulated over a long period of time as attested by Antoniou [22] and Hassan [23] in their studies. In addition, the results show that the subsurface conditions at El Fustat consist of silt, clay and fine sand, where, this city suffers from a rise of groundwater levels that characterized by high saline index.…”

Textiles are civilizational treasures and dresses are forms of cultural heritage, because clothing is a visual means of communicating ideas and values. It is very fragile, though, and can survive only in very good conservation conditions. Most become nearly completely destroyed due to ageing. This paper presents the documentation and conservation processes of a children Coptic tunic. The tunic is stored in the Egyptian textile museum. It dates to Coptic period, and it was made mostly of linen textile. Stereo microscopy was used in the identification of the textile structure and SEM microscopy associated with EDAX was used to identify the morphology of the fibers, recording the deterioration levels, and analysis the dirty threads. The analytical results proved that the textile structure involves plain weave openwork technique. The tunic was made of linen fibers. There are traces of calcium, chlorine, silicon, sulphide, magnesium and aluminum, elements. Within the same context, it could be said that the main challenges of conservation were the poor condition of the tunic and the previous supporting. The main conservation treatments were surface cleaning and supporting the dress on silk crepeline. The previous supporting stitches were removed. Finally, the tunic was prepared for museum display.

“…Analytical models for selecting an appropriate dewatering system and risk assessment may offer designers and contractors an additional tool for large to small-scale construction operations (Ye et al [19]; Jurado et al [12]; Golestanifar & Ahangari [20]). Numerical modeling software, such as MODFLOW, a three-dimensional groundwater flow program developed by the U.S. Geological Survey (USGS), that simulates the drawdown characteristics of dewatering systems, also can be advantageous (Hassan et al [21]). These computer based tools may not be currently utilized in the transportation construction industry, or for other vital infrastructure such as deep utility installations, as with the sanitary sewer main discussed by Mokwa et al [18].…”

Areas that once were deemed unsuitable for construction due to a high water table are now being developed to meet the needs of an increasing population. With the decline in land availability to build or expand highway networks above ground, underground facilities, such as mass-transit lines, may represent the future of transportation. Underground structures naturally require the control of groundwater to complete construction. A review of common dewatering systems and methods used in the construction of transportation facilities found that similar techniques are used in other industries. Also, scant few case studies document dewatering problems although they represent a key component of common construction claims in the civil engineering industry. A common thread among all construction initiatives is the need for thorough subsurface site investigation. The uncertainty of subsurface conditions related to groundwater issues has resulted in insurance claims and litigation reaching disproportionately high numbers in civil engineering construction. Better assessments of hydrogeological formations may help to mitigate potential groundwater control problems.
