Water Quality Assessment of the River Nile System:An Overview

引用

Biomedical and Environmental Sciences 2004年第1期17卷 87-100页

作者： RIFAAT A.WAHAAB mohamed I.badawy National Research Center DokkiCairoEgyptNational Research CenterDokkiCairoEgypt

Objectives The main objective of the present article is to assess and evaluate the characteristics of the Nile water system , and identify the major sources of pollution and its environmental and health consequences. The article is also aimed to highlight the importance of water management via re-use and recycle of treated effluents for industrial purpose and for cultivation of desert land. Method An intensive effort was made by the authors to collect, assess and compile the available data about the River Nile. Physico-chemical analyses were conducted to check the validity of the collected data. For the determination of micro-pollutants, Gas Chromatography (GC) and High Performance Liquid Chromatography (HPLC) were used. Heavy metals were also determined to investigate the level of industrial pollution in the river system. Results The available data revealed that the river receives a large quantity of industrial, agriculture and domestic wastewater. It is worth mentioning that the river is still able to recover in virtually all the locations, with very little exception. This is due to the high dilution ratio. The collected data confirmed the presence of high concentrations of chromium and manganese in all sediment samples. The residues of organo-chlorine insecticides were detected in virtually all locations. However, the levels of such residues are usually below the limit set by the WHO for use as drinking water. The most polluted lakes are Lake Maryut and Lake Manzala. Groundwater pollution is closely related to adjacent (polluted) surface waters. High concentrations of nutrients, ***, sulfur, heavy metals, etc. have been observed in the shallow groundwater, largely surpassing WHO standards for drinking water use. Conclusion A regular and continuous monitoring scheme shall be developed for the River Nile system. The environmental law shall be enforced to prohibit the discharge of wastewater (agricultural, domestic or industrial) to River Nile system.

Food and Nutrition Sciences 2013年第1期4卷 90-99页

作者： Yousif Abd El-Aziz Elhassaneen Amal mohamed El-badawy Department of Adult Health Care Faculty of Nursing Minoufiya University Shebin El-Kom Egypt. Department of Nutrition and Food Science Faculty of Home Economics Minoufiya University Shebin El-Kom Egypt

The effect of ingesting charcoal-broiled beefburgers (CBB) on the liver functions and nonenzymatic antioxidant levels in human blood was examined in twenty-nine healthy individually males (mean age 21.65 ± 1.32 years, range 20.32 - 22.42 years), non-smokers and had no occupational exposure to PAHs, who consumed two charcoal grilled beefburger per day (mean weight 70 gmper each) at lunch time over 28 consecutive days. The mean daily intake of PAH during the consumption period was 3431 ng and the mean daily intake of PAH per kg body wt/day was 46 ng. Blood samples were collected from each subject 7, 14, 21 and 28 days before, during, and after the beefburgers consumption period. glutamic-oxaloacetic transaminase (GOT), glutamic-pyruvate transaminase (GPT) and alkaline phosphatase (ALP) were significantly higher in serum of subjects during CBB consumption period compared with those of before CBB consumption ones. All of the enzyme activities still increased upper the baseline levels, before CBB consumption period, by four week after charcoal broiled meat consumption ended. In contrary, the levels of non-enzymatic antioxidants include albumin (ALB), glutathione in serum (GSH-S) and erythrocytes (GSH-E) were significantly lower in subjects during CBB consumption period compared with those of before CBB consumption ones. All of the non-enzymatic antioxidant levels decreased to near baseline levels, before CBB consumption period, by four week after charcoal broiled meat consumption ended. Results suggested that non-enzymatic antioxidants defense system of serum and erythrocytes was depressed and the erythrocytes as well as liver cells were exposed to oxidant stress due to oral exposure of PAH.

The Hidden Value of Assessing Right Ventricular Performance with Exercise in Hypertensive Patients with Left Ventricular Diastolic Dysfunction

引用

World Journal of Cardiovascular Diseases 2021年第6期11卷 261-276页

作者： mohamed Sanhoury Samir Rafla Tarek El badawy Radwa Momtaz Khalil Cardiology Department Faculty of Medicine Alexandria University Alexandria Egypt

Background: Right ventricular (RV) dysfunction could develop during exercise in patients with both hypertension and left ventricular diastolic dysfunction and may contribute to the patient symptoms. The objective is to assess RV function, both at rest and during exercise in patients with hypertension and left ventricular diastolic dysfunction. Methods: We included 30 patients with hypertension and resting LV diastolic dysfunction. The systolic function of the right ventricle was assessed by TAPSE (Tricuspid Annular Plane Systolic Excursion) and S, while E/A ratio, annular lateral E’, E/E’ and E’/A’ were used to measure diastolic function. The global function of the right ventricle was assessed by measuring the right indexed myocardial performance. The dimensions and pulmonary pressures were also measured. Results: The following parameters of RV systolic function were increased significantly with exercise: TAPSE (P = 0.0054), S’ (P = 0.0045). Moreover, the following diastolic parameters of the RV increased significantly with exercise: E/E’ (P = 0.05), A’ (P = 0.04). The global RV function showed also a significant increase (P = 0.0011).

An Experimental Study on Using Laser for Cleaning Metal Threads

引用

Journal of Materials Science and Chemical Engineering 2020年第4期8卷 46-63页

作者： Neama A. Shehata mohamed A. Marouf badawy M. Ismail Department of Archeology Restoration Sohag National Museum Ministry of Tourism and Antiquities Sohag Egypt Conservation Department Faculty of Archaeology Sohag University Sohag Egypt Conservation Department Faculty of Archaeology Luxor University Luxor Egypt

Samples of metal threads were prepared, underwent artificial aging, and cleaned using laser applications to define the efficiency of cleaning that gives the best results without affecting the components of the thread, including metal, fibers, or dyes. The present study aimed to investigate and evaluate laser cleaning of the corroded metal embroidery, revealing the chemical composition of the corrosion and prop and evaluating the effects of laser cleaning on the surface of the metal threads. It utilized SEM and LM to provide morphological information about the surface and the cleaning effect. Moreover, SEM-EDX was used to define the elemental composition, and XRD was employed to offer information on the metal. The restoration of cultural heritage depends on defining the devastating changes to the man-made pieces. It compares pre-and post-restoration conditions of the object (e.g. painting, photography, and material analysis), controlling the conditions that are almost irrevocable. An Interval Digital Macro-photography is employed to control the corrosion PS tests for a long period of museum exhibition [1].
