Several problems have emerged as a result of urban expansion or the connection of urban areas with rural areas. This process has led to the urbanization of rural areas, and to have overlapping edges and margins of areas, which were outside the basic design of the city. Accordingly, the present research assumes that the accelerating growth of Baghdad population has contributed significantly to the process of unplanned urbanization. Thus, the study aims to examine the factors that have led to an increase of urban sprawl at the expense of the agricultural land. The study has thus adopted the descriptive, analytical, and historical approaches relying on the simple linear regression method to predict the phenomenon of urban expansion and its impact on the agricultural land. It has also included illustrative maps used in the preparation of geographic information technology (GIS).The study has concluded that the events of Iraq after 2003, the absence of legal rules, weak legislation, and the successive large immigrations from the countryside to the city have all led directly to a great increase in the process of housing expansion at the expense of agricultural lands. The research recommended the necessity of finding final solutions to the problem of encroachment on agricultural lands, establishing new and low-cost urban housing with full facilities and services, simplifying the procedures of building licensing, and reducing fees.
يُعد الوزن الاقتصادي للهند من أبرز عناصر قوتها الجيوسياسية، إذ تُصنف الهند ضمن أكبر الاقتصادات عالميًا، مدعومة بحجم سكاني ضخم وسوق استهلاكي واسع ونمو متسارع في قطاعات الصناعة والخدمات والتكنولوجيا. حقق الاقتصاد الهندي نموًا قويًا خلال السنوات الأخيرة، مع استمرار معدل نمو الناتج المحلي ضمن نطاق مرتفع مقارنة بكبرى الاقتصادات العالمية، حيث تتوقع عدة مؤسسات دولية نموًا يقارب 6.3–7% خلال 2026–2027.

... Show MoreIn this paper, an enhanced artificial potential field (EAPF) planner is introduced. This planner is proposed to rapidly find online solutions for the mobile robot path planning problems, when the underlying environment contains obstacles with unknown locations and sizes. The classical artificial potential field represents both the repulsive force due to the detected obstacle and the attractive force due to the target. These forces can be considered as the primary directional indicator for the mobile robot. However, the classical artificial potential field has many drawbacks. So, we suggest two secondary forces which are called the midpoint

People migrate and embrace a new identity for different reasons. They find themselves in a state of internal conflict as they navigate the tension between their newly adopted identities and their old ones. The individual is haunted and overwhelmed by their previous experiences. This research explores the universality of the subject matter by examining the motivations underlying the adoption of a new identity in a distinct geographical and temporal context. This paper examines the literary works of Kincaid's Lucy (1990) and Blasim's "The Nightmares of Carlos Fuentes" (2014). Kincaid’s pro

Which have been evolved from the main sequence phase through Asymptotic Giant Branch (AGB). The calculations were done by adopted Synthetic Model showed the following results: 1- Mass loss on the AGB phase consists of two phases for period (P <500) days and for (P>500) days; 2- the mass loss rate exponentially increases with the pulsation periods; 3- The expansion velocity VAGB for our stars are calculated according to the three assumptions; 4- the terminal velocity depends on several factors likes metallicity and luminosity. The calculations indicated that a super wind phase (S.W) developed on the A
... Show MoreSuccessfully, theoretical equations were established to study the effect of solvent polarities on the electron current density, fill factor and efficiencies of Tris (8-hydroxy) quinoline aluminum (Alq3)/ ZnO solar cells. Three different solvents studied in this theoretical works, namely 1-propanol, ethanol and acetonitrile. The quantum model of transition energy in donor–acceptor system was used to derive a current formula. After that, it has been used to calculate the fill factor and the efficiency of the solar cell. The calculations indicated that the efficiency of the solar cell is influenced by the polarity of solvents. The best performance was for the solar cell based on acetonitrile as a solvent with electron current density of (5.0

Show MoreThe local asphalt concrete fracture properties represented by the fracture energy, J-integral, and stress intensity factor are calculated from the results of the three point bending beam test made for pre notches beams specimens with deformation rate of 1.27 mm/min. The results revealed that the stress intensity factor has increased by more than 40% when decreasing the testing temperature 10˚C and increasing the notch depth from 5 to 30mm. The change of asphalt type and content have a limited effect of less than 6%.
