Fertile agriculture areas in the Nile-Delta of Egypt are constantly deteriorating mainly due to urbanization. Remote sensing and GIS technology have proven their great ability to explore the problems of urbanization and their impacts on agricultural lands. The main objectives of this study were to provide an accurate assessment of urban areas in Dakahlia Governorate and to study the impact of urbanization on agricultural lands during the period from 1984 to 2014. Accordingly, Landsat TM images in 1984 and ETM+ in 2002 and 2011 and OLI-TIRS in 2014 were used to study spatial and temporal changes in both urban and agricultural lands in Dakahlia Governorate. Normalized difference vegetation index (NDVI), Normalized difference built-up index (NDBI) and soil adjusted vegetation index (SAVI) were used to extract urban versus agricultural lands from these multitemporal Landsat images. The results indicated that the annual increase in urban lands was about 2.54 km<sup>2</sup> per year during the period from 1984 to 2002 and about 4.01 km<sup>2</sup> per year during the period from 2002 to 2011. However, the rate was highly increased by about 47.99 km<sup>2</sup> per year during the period from 2011and 2014. It was also observed that the increase in urban areas was clustered around old cities and villages before 2011; however it took a random pattern after 2011. Accuracy assessment of the studied indices indicated that the NDBI has the highest accuracy. It could be concluded that urban encroachment over the fertile agricultural lands is the most serious process that result in fertile land degradation in Dakahlia Governorate.</strong>https://bfemu.journals.ekb.eg/article_102842_2507e2d7bbad9e880e2808269badcfa9.pdfMansoura University, Faculty of EngineeringMEJ- Mansoura Engineering Journal1110-092339420200714Estimation of Salt Balance in Salt-Affected Ecosystems in Arid Areas, Case Study: El Fayoum Depression, Egypt.152610284810.21608/bfemu.2020.102848ENA.El-SheikhHydrology Department, Desert Research Center, Cairo, EgyptM. I.GadHydrology Department., Desert Research Center., Cairo., Egypt.Journal Article20140923<strong>El Fayoum depression is a semi-closed depression located about 100 Km southwest of Cairo-Egypt It occupies an area of about 1200 Km<sup>2</sup>. Due to the complex geological and hydrological conditions of that area, water logging problem and soil salinization affect great parts of the cultivated areas. The geological conditions are manifested in the rich content of clay in the Quaternary aquifer, the relative small aquifer thickness and the dominance of faulted and fractured limestone at the base and on the peripheries. On the other hand, the hydrological conditions include the occurrence of a thick net of irrigation system and presence of huge surface water bodies; e.g. Qarun lake and Wadi El Rayan lakes. Moreover, the groundwater depths vary from few centimeters below ground surface to 7.51 m which reflect a critical soil salt-affected problem. The present paper throws light on the salt balance of the groundwater regime. The estimation of the input and output components is carried out based on the field measurements during 2006. The estimated mean annual salt influx reaches 2.05 million tons. The Output component includes the salt efflux through the drainage network, subsurface groundwater flow and the salinity losses due to plant uptake. The estimated annual mean value of salt efflux from these three components reaches 3.8 million tons. The average annual storage component is estimated to be -1.75 million tons. The estimation of salt balance shows that the groundwater or/and soil water receive an excess of annual salt content of 1.75 million tons due to leaching process of evaporites and clay lenses during its flow from the upstream till it reaches the downstream area (Qarun Lake). Mitigation of imbalanced salt load through minimizing the losses from drainage network and using low consumed cop pattern is highly recommended.</strong>https://bfemu.journals.ekb.eg/article_102848_9f2441e0a0025375d580f06c0203f861.pdfMansoura University, Faculty of EngineeringMEJ- Mansoura Engineering Journal1110-092339420200714Economics of Using Marble Powder in Self-Compacting Concrete in Egypt.274110285310.21608/bfemu.2020.102853ENAhmed H.Abdel RaheemStructural Engineering Department, Mansoura University, Faculty of Engineering , MansouraAhmed M.TahwiaResearcher at Structural Engineering Department, Mansoura University, Faculty of Engineering , MansouraMohamed A.KandilResearcher at Structural Engineering Department, Mansoura University, Faculty of Engineering , Mansoura.

After connecting distributed generators (DG), part of the system may no longer be radial, which means that the coordination might not hold. The objective of protective relay coordination in an interconnected power system is to achieve selectivity without sacrificing sensitivity and fast fault clearance time. In this paper a novel method based on clonal selection algorithm of artificial immune system (AIS) is proposed for optimal coordination of overcurrent relays in distribution system connected to DGs. This method is used to find the optimal Time Setting Multiplier (TMS) and the pickup current (Ip). The proposed algorithm is utilized to obtain the optimal setting of overcurrent relays and make it adaptive with any DG penetration level and location.

This principle can be developed by further reducing the dimensionality of the electron's environment from a two-dimensional quantum well to a one-dimensional quantum wire and eventually to a zero-dimensional quantum dot. The dimensionality refers to the number of degrees of freedom of the electron momentum, so the electron is confined across two directions within a quantum wire, rather than just the one in a quantum well. In a quantum dot the electron is confined in all three-dimensions, thus reducing the degrees of freedom to zero.

Its principle is to drill a circular hole at or close to the crack tip to transform the crack into a notch, reducing in this way its stress concentration effect. In the present study, the stop-hole method was investigated with creating a non circular hole. The aim of the present work is to obtain an optimum stop hole shape that gives maximum fatigue crack initiation life. Fatigue crack initiation life depends at least on the crack size and on the hole diameter. An optimization technique had been used and a finite element program had been built to find this optimum shape of stop hole. It was found that the fatigue life obtained by using the optimum hole shape ranges from 2 to 9 times the fatigue life obtained by using the circular holes depending on the initial hole size and initial crack length. The effect of this optimum hole shape on crack reinitiating life for different specimen geometries has been studied. It was found that the optimum hole shape increased the initial fatigue life for all specimens used whatever its geometry was. A global optimum hole shape (which is practically suitable for all geometries ) is defined. Global optimum hole shape helps engineers to use this global hole shape directly in practice without carrying out any calculation much like the use of the stop hole size found in the literature. Opposite to the traditional stress concentration factor minimization problem where the nominal area remains constant during optimization, here it is allowed to vary nominal area using design variables resulting in decreasing of the nominal stress in addition to decreasing of the stress concentration factor. This leads to higher fatigue life compared to previous studies.</strong>https://bfemu.journals.ekb.eg/article_102841_1df72502b53f86523ddf6e7dfb751560.pdfMansoura University, Faculty of EngineeringMEJ- Mansoura Engineering Journal1110-092339420211010Biogas Utilization Model Using Linear Programming for Layer Farms.11820158510.21608/bfemu.2021.201585ENIbrahim Gar Al-AlamRashedMathematics and Engineering Physics Department, Faculty of Engineering, El-Mansoura University, Mansoura, Egypt.Hesham NagyAbdel-MageedAgricultural Engineering Department, Faculty of Agriculture, Mansoura University.Rabab EzzatMatoukAgricultural Engineering Department, Faculty of Engineering, Mansoura University, Mansoura, Egypt.Journal Article20141010<strong>The gap in demand and supply of energy can be met by optimal allocation of available energy resources. For farmers throughout the world, energy inputs represent a major and rapidly increasing cost.

As such energy planning problem is inherently optimization problem. The model has been optimized using LINGO software version 12.0. The optimization problem of biogas energy produced on-site has been executed from the economic point of view. The analysis assumed no thermal energy storage capacity is available to address generation/load mismatch. Based on the optimal solution biogas energy can be utilized to cover great portion of the annual electricity and heat demands by about 95% and 99%, respectively. This model is considered a powerful tool for analyzing competition between two routes of the rational use of " <em>chemical potential energy" </em>with independent demand, which can be used in a small-scale rural poultry farm. In addition, sensitivity analyses have been elaborates in order to show how the optimal solution would vary due to some key parameters including energy demands, conversion efficiencies and relevant costa.
