The researchers followed the descriptive and analytical approach of the sources and reports issued by the institutions related to the sewage stations in the Gaza Strip. The study also included interviews with engineers at the station to analyze and assess the risks to the North station, to identify indicators to prevent flooding of Umm al-Nasr village, and to identify preventive measures to avoid disasters. The study also recommended the necessity of finishing the development of the North Emergency Station Project to accommodate the cumulative increase in the amount of treated water, as well as work on the preparation of contingency plans to deal with the expected risks and the preparation of preparedness and response procedures for each risk.

This study was designed so that this waste is recycled to be added to diesel fuel and to verify its suitability as a composite fuel. Method: This study aimed to investigate the thermal combustion behavior of lemon peel powder, LPP, and orange peel powder, OPP biomass composite fuel diesel. The citrus peel was dried and ground to a powder material of 450-750 µm in size, then mixed in different percentages with diesel fuel. Different parameters were controlled to improve the composite fuel characteristic. The pyrolysis experiments of the diesel/citrus composite fuel were conducted in an internal combustion engine. Results: The results showed that the citrus/diesel composite fuel sustains its combustion properties at 30% of the added citrus peel powder, with a reduc...

Different parameters were controlled to improve the composite fuel characteristic. The pyrolysis experiments of the diesel/citrus composite fuel were conducted in an internal combustion engine. Results: The results showed that the citrus/diesel composite fuel sustains its combustion properties at 30% of the added citrus peel powder, with a reduction of harmful emissions. The results showed that calorific values of diesel containing 30% LPP or 15% LPP + 15% OPP were very close to that of pure diesel. The maximum calorific values were obtained at α = 0.85, 0.80, and 0.90 for 30% OPP, 30% LPP, and 15% OPP + 15% LPP composite fuels respectively. It was found that the addition of homogenization material and combustion activator to the composite fuel raised the maximum temperature of combustion by 230 °C, 200 °C, and 330 °C for 30% OPP, 30% LPP, and 15% OPP + 15% LPP respectively. The TGA analysis of lemon and orange showed that the weight loss has proceeded in three stages, the first at 150°C-200 °C due to water evaporation, the second at 400 °C due to hydrolysis of cellulose and hemicellulose, and the third at 600 °C due to combustion of fuel material forming carbon residue. Conclusion: The composite fuel without additives showed the highest combustion temperature at about 600 °C, while the maximum combustion temperature for the composite fuel with additives was achieved at 800 °C at a shorter time.

The possibility of using diesel, pomace and alzibar composite fuel in heat installations in the power industry as a composite of alternative fuels is limited by ratios of the component, homogeneity and fuel properties. The properties of the fuels and the effect of some chemical additives are presented including thermal comparative between the composite fuel and pure diesel. The article presents the possibility of using a composite fuel -code B2 (20% alzibar, 40% diesel and 40% Pomace) as an alternative for diesel with a high thermal efficiency. The results showed the effect of the added thermal activators such as ethanol in reducing the amount of the remaining results of fuel combustion process by adding 5% ethanol.

A plan that contains procedures for managing the displacement of the citizens according to the type of the disaster and the suggested safe shelters were prepared. Individuals infected with COVID-19 are isolated in central places or their home. Responding procedures for the emergency committee in Umm al-Nasr municipality were prepared to deal with displaced people. A mathematical model was designed to simulate choosing a shelter for the citizens of this village depending on the type of crisis. The results showed the different conditions that may affect the displacement operation, such as the type of shelter, the allocated area, the number of...

In addition, a mathematical equation was designed to calculate the strength of the true steadfastness of the society to defend the community in the event of war. The researchers used the analytical descriptive approach and the interview with the officials in the municipality of the village. The most important results of this study were the preparation of the risk matrix for the village of Umm al-Nasr by identifying the risks and analyzing them, determining the consequences and probability of each disaster threatening the village, designing a model showing the emergency operations and the effective institutions, an...

In an attempt to address this research's nature is purely experimental, using the existing laboratory at the College of Science and Technology, City of K/Younis, Gaza Strip. A particular finding emerges in this study which argues for water energy being important because it may well substitute the shortages in energy power supply in developing countries. A hyper station is invented in this study. The aim is not only to produce power electricity from sea water in Gaza, or reduce the cost of energy production but also a desalination of the sea water is achieved.

Not surprisingly, therefore, alternative solutions have been sought ever since which replace the use of diesel in car engines with all kinds of vegetable oils. Nevertheless, such alternative shows drawbacks in relation to badly affecting the surrounding environment. This study focuses on these drawbacks in an effort to minimise environmental pollution emerged due to using vegetable oil as an alternative energy resource to fuel engine. In so doing, analysis in this article uses the Gaza Strip as a particular case. A comparison is utilised in this case through the lens of heat efficiency which compares between the proportions of environmental pollution, firstly emerged due to the combustion of vegetable oil and secondly occurred in the engine diesel. The next step seeks to minimize the proportion adopting handling heating that uses additional materials, small organic molecules, acetone and toluene. These materials reduce environmental pollution in comparison with diesel engine, thereby enhancing its efficiency. Analysis in this study uses three different mixtures of alternative fuels based on vegetable oil (VO). In the first fuel, the VO contains different percentage of acetone.

The last fuel shows 80%VO, 20% diesel and different percentage of acetone. This study argues that the best performance similarly to the efficiency of fuel diesel was measured at 2%-10% acetone for the first mixture, 20%-40% diesel for the second one and at 5%-10% acetone for the last one. From the perspective of ecology, the third mixture reveals the best outcomes amongst others because it minimises the CO 2 emissions in relation to the VO. It reaches between 13.5% and 15%. In a similar vein, the NO 2 emission was minimized at a percentage that reaches between 4% and 16%. All the above results were accepted at α=1 due to balancing between CO 2 and NO 2 emissions.
