Crude oil spills in the environment; either in soil or in water of rivers and seas is considered a great environmental problem. That is due to the presence of crude oil in the open water has a negative impact on the ecosystem of fishes and their respiration. Furthermore, crude oil has poisoning components which harm the ecological system. The effective method of treating the spilled crude oil in the environment is the formation of dispersions for this oil, which prevents the accumulation of the crude oil in specific area and allows its biodegradation by the microorganisms. Here, environmentally friendly nonionic surfactants, namely: Tween-20,40,60 and 80 were investigated as dispersants for dispersing the crude oil spilled in the ecosystem. The study showed that the polyethylene glycol chain length of the different tweens has a great influence on their ability to form crude oil emulsions. Furthermore, the surface activity of the investigated surfactants was an important factor in their crude oil dispersing function.

In this work, chemically modified corncobs was used as coagulant in waste water treatment. Thischemical modification was performed by allowing powdered corncobs to react with ethylene diamintetraacetic acid (EDTA) and epichlorohydrin in alkaline medium. Factor affecting the nitrogen content in the produced amphoteric corncobs (ACC) e.g. reaction time, temperature and amount of (EDTA) added were studied. The product obtained (ACC) was characterized using analytical and spectrophotometer tools, elemental and thermogravimetrical analysis besides FTIR and1H-NMR .The product obtained was characterized by FT-IR,1H-NMR spectroscopy. The adsorption efficiency of (ACC) for metal ions in water as Cu and Zn was determined using atomic absorption spectrometry (AAS). It has been shown that there is a noticeable change in the specification of the treated water by the suggested (ACC) exemplified by least amount of organic matter, turbidity, solid substances and other elements existing in waste water.

Nowadays, the Sensor Networks offer many benefits to the environment and humanity, starting with monitoring environmental phenomena, monitoring and control of industrial facilities/processes (especially in Nuclear Power Plants , NPPs) and following up on the health status of the elderly. In nuclear field, radiation monitoring systems and networks are among the most important systems used to the assessment of nuclear safety and radiation protection processes. Furthermore these networks are used as inspection tool of occupational radiation protection to predict any states of diffraction or deviation of the correct operating factors to maintain the integrity of the internal or the surrounding environment of the nuclear facilities. This paper presents a prototype (hand made prototype) of a sensor network node (SN) for air quality monitoring system which can be used indoors or outdoors. The proposed SN is based on the AVR microcontroller and is characterized by the small size, low power consumption, simplicity, and lower cost. The microcontroller, µC, performs specific tasks, transfers data, and controls the functionality of the SN. It is often used as the brain in many embedded systems because of its great abilities, flexibility, ease of programming, low cost, and low power consumption. So that it was a compelling argument to use µC in the design of the sensor network.

The agricultural area in Egypt is the largest consumer of water and still requires more water to expand. Any changes in Nile water supply due to climate change would threaten the agricultural water productivities, both physical productivity and economic productivity, and the food security in Egypt. The objective of the current paper is to investigate the impacts of Nile supply reduction on the agricultural water productivities and food security in Egypt using the Agriculture Sector Model in Egypt (ASME). The results showed that the reduction in Nile supply will either increase or decrease the areas of different crops, and generally will decrease the total cropped area. Regarding the food security, all indicators refer to a slight decline in the food security progress in terms of reduction of water availability, self-sufficiency of strategic food crops, and net virtual water import. The reduction in Nile supply will also deteriorate the economic situation, which can be confirmed by the reduction in agricultural productivity, consumer-producer surplus, and number of jobs as well as the increase in net imports’ value and water marginal value. The current study recommends implementing adaptation measures to efficiently use the available water resources and to increase the agricultural productivity per unit area.

The study had many proposals and recommendations that could contribute to activate the role of parent-teacher councils leading to the development of environmental responsibility and participation of students and the development of relevant values, including the following:
Educational curricula should have good meanings for improving the school environment and show the role of parents 'and teachers' councils in improving the school environment.
The Ministry of Education must provide the necessary financial support for this Council, in order to encourage parents to join this Council.
The participation of mothers in parents' councils must be increased significantly because they are an essential part of the relationship between home and school.
It is necessary to open the door to the surrounding community to present its services and proposals for the development of school administration, especially in participating in decisions, and not follow the closed door policy of the school administration,
Civil society organizations should provide trips, summer camps and factory visits to students in order to raise the level of achievement
Community institutions concerned should provide care and support to secondary school staff to raise their scientific, technical and educational level.

Political participation is one of the axes of the field of psychosocial sciences, which examines the positive role of the individual in political life through the right to vote or to vote in the elections or to take care of political issues and discuss them with others or membership in organizations.
And political participation The individual learns soft practices that help him to co-exist with others in society through the institutions of society, which helps this individual to coexist with this behavior. Trying to study
Examine the relationship of political participation to the five major personal factors among different age groups
Examine the relationship of political participation to the five major personality factors in individuals from different environments
The sample of the study was selected in two stages. In the first phase, a sample of 652 was applied. After excluding random responses and missing responses, the study sample reached (550) male and female members (20-40 years) Urban - rural environment - coastal environment).
Tools were used: the scale of political participation - the list of major factors of personality.
The results of the study revealed a statistically significant correlation between the variables of political participation and the major factors of personality in the total sample (rural - urban - coastal) and the existence of a relationship between personality characteristics and political behavior. And that individuals with a high degree of openness to experience, extrapolation, acceptability, living conscience and less in the nepotism are more oriented towards political participation than others.
There are statistically significant differences between different environments (urban - rural - coastal) in the level of major personal factors in favor of the urban environment and then the coastal environment and rural environment.
And the existence of statistically significant differences between different environments (urban - rural - coastal) in the level of political participation in favor of the environment for urban and then the coastal environment and the environment
The most important recommendations were:
Give young people the real opportunity to activate their leadership role within the community with the rehabilitation and refinement of modern programs to develop their leadership abilities.
Urging the official authorities concerned to redouble their efforts to make the youth group a key element in the process of building and development in society.
Attention to spreading political awareness among the members of society, which motivates them to exercise their political rights.

The term "Oasis" is used to express a natural phenomenon in desert areas. It is a low-lying isolated area surrounded by desert from each side. Siwa Oasis is a natural depression in Western Sahara, which has a low altitude of about 23 meters below sea level. It has an area of about 250,000 feddans, of which about 209,400 feddans are cultivated and irrigated through a number of wells and springs. As a result of continuous and continuous flow of water in excess of 33 million m3 (Fathi Hammad, 2001) , In the absence of an efficient and efficient sewage system, in addition to the low efficiency of the existing drainage system, the water accumulation and accumulation of water in the low areas of the oasis has created a number of lakes, causing the problem of rising water level, Negatively affect their productivity and threaten the entire ecosystem of the oasis. The study aimed to identify the most important returns and costs that affect the cultivation of jatropha and the economic feasibility of planting them. The research relied on both descriptive and quantitative methods. The results proved an IRR of about 27%, which is higher than the opportunity cost available. For the investment in Egyptian banks for 2018, which is an interest rate of about 17%, and the rate of return on costs was estimated at1.6 and the net present value (91025.6), The study recommended the exploitation of agricultural waste water economically as a waste resource causing many economic and environmental problems and encouraging investments in this field. dunes, and the provision of new jobs by increasing the areas of new land, and recommended the research the need to exploit agricultural wastewater economically as a waste resource causing many economic and environmental problems and encourage investments in This area.

The natural resources (soil-plant-animal-aquatic situation) in North Sinai are experiencing a deterioration due to the impact of climatic, environmental and the human activities. This has led to a reduction in biodiversityand desertication of wide areas in North Sinai which decrease the income of the farmers.It important study the various effects of agriculture projects to adapt with climatic effects to achieve the desired uses of the available resources and the sustainability of these projects. Therefore, the aim of this research is to evaluate the ability of prouject to solve the proplems of faremers in North Sinai. The research depends on the use of descriptive analytical approach to present and analyze the research problem as well as quantitative analysis to measure the production and economic efficiency of the project based on achieving objectives through the various statistical methods. It also relied on secondary and preliminary data. The predictive value of the effect of rainfall on productivity was 0.544, 0.097, -0.022, 3.419, 37.719 kg / feddan for alfalfa, barley, feed beet, pearl millet and sorghum respectively, while the predictive values of the effect of temperature on productivity were -0.523, -0.18, 4.900, 1.818, 1.493 kg / feedan respectively. Theeffect of humidity were -0.637, 0.118, 0.861, -5.658, -28.471 kg / feedan respectively. For the effect of wind speed on productivity, the values were -3.613, -0.112, -3.857, 6.148, -1.624 respectively The effect of climate change factors was 15.1, 52.8, 62.8, 20.4 and 39% on the productivity of alfalfa, barley, fodder, pearl millet and sorghum crops, respectivily, while84.9, 47.2, 37.2, 79.6 and 61% were related to the effect of other environmental factors and human productivity. For the economic evaluation of the project, it was noted that the use of integrated agricultural practices with the start of the project activities led to an evolution in the economic productivity indicators of the cultivated crops whem compared with the use of traditional agricultural practices before the start of the project activities. (prouctivity – total costs – total revenues – net profit - ratio of revenues to costs - Investor's revenue criterion). Therefore, the study recommends ito increase the number of agricultural projects in North Sinai, which help farmers on modern agricultural techniques in order to achieve the best use of the available resources in the studied region and work on producing new strains of crops that adapt to the conditions of the region to increase its productivity.
