Eyes of Optimism Look for Freedom in Langston Hughes' Selected Poems
...Show More Authors

The current study tackles how slavery and racial segregation, which have obviously made an enormous impact in the United States of America for many years, can be defeated through optimism. The study opens with an introduction that clarifies some background about Langston Hughes as a poet who writes against slavery and oppression done to the American Blacks during an era which was known for racial segregation in the United States of America. The poet sheds light , in his poetry, upon the role of African Americans in activating hope and optimism to get freedom which has been reached at the end. The first section of the study analyzes the meaning of slavery and segregation as reflected in some selected poems, showing the oppressive face of the Whites against the Blacks. The poems exhibit simplicity as the poet's main strategy to raise one of the most sensitive cases in history; that is slavery. The second section comes next where the poet works on instigating his people towards the necessity of keeping on optimism as the key that will lead to man's freedom . Finally , the conclusion that sums up Hughes' message of how African Americans must convey the optimistic view throughout the African American history for eternal freedom.       

   African Americans have suffered from racial discrimination for years as they have been used as slaves. They also have to face an inner migration from the South of America where they are used as workers in the farms which belong to the White owners , and to some blacks who managed to have prosperity at the expense of the poor Blacks. Poverty has dominated their life and most of them have become jobless , in addition to being uneducated. The poet writes his poems in time that literature , in general, and poetry , in particular, represent the spring from which the Blacks start their revolution against racism. He presents the African spirit of their ancestors who are known for their struggle and strife making their cause extend to include the next generations. Optimism and hope can be seen in these old spirits as a motivation for the present and the future as well. Hughes depends on some images that are taken from the Blacks' history with other images are seen in the present in order to build the future that the Blacks themselves look for ; the future of having freedom and equality. Being desperate is something dangerous and cannot lead to build up an optimistic generation in the African-American community. The poet's message is to run after the eye which looks at the optimistic spirit which put the reader in the position of evaluating the African-American history that celebrates the human strife in the past and the present by reminding his people of hope and optimism as the main source for their battle against racial discrimination.

Enhanced Antifouling in Flat-Sheet Polyphenylsulfone Membranes Incorporating Graphene Oxide–Tungsten Oxide for Ultrafiltration Applications
...Show More Authors

In this study tungsten oxide and graphene oxide (GO-WO2.89) were successfully combined using the ultra-sonication method and embedded with polyphenylsulfone (PPSU) to prepare novel low-fouling membranes for ultrafiltration applications. The properties of the modified membranes and performance were investigated using Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), contact angle (CA), water permeation flux, and bovine serum albumin (BSA) rejection. It was found that the modified PPSU membrane fabricated from 0.1 wt.% of GO-WO2.89 possessed the best characteristics, with a 40.82° contact angle and 92.94% porosity. The permeation flux of the best membrane was the highest. The pure water permeation f

Recent Developments in Membrane, Adsorption, and Electrochemical Sustainable Approaches for Cadmium Removal from Contaminated Water
...Show More Authors

The issue of cadmium (Cd(II)) contamination of the water is a serious concern of the environmental and health problem, and this requires effective technology to remove the problem of toxic element. It is the purpose of this review paper to give an overview of several techniques of cadmium removal, such as polymer membranes and composites, adsorption using green materials, and electrochemical methods. The important conclusions are presented regarding the effectiveness of the polymer and composite membranes; e.g., the efficacy of the PES/HPEI-SH membrane that reached 99% removal of Cd(II) in 20 min with adsorption capacity of 135.59 mg/cm2, and the PVA/IC/PANI/GO nanofiber composite that indicates high adsorption of the 459 mg/g.

Abstract<p>Study of determining the optimal future field development has been done in a sector of South Rumaila oil field/ main pay. The aspects of net present value (economic evaluation) as objective function have been adopted in the present study.</p><p>Many different future prediction cases have been studied to determine the optimal production future scenario. The first future scenario was without water injection and the second and third with 7500 surface bbls/day and 15000 surface bbls/day water injection per well, respectively. At the beginning, the runs have been made to 2028 years, the results showed that the optimal future scenario is continuing without water in</p> ... Show More

Accident Management System Based on Vehicular Network for an Intelligent Transportation System in Urban Environments
...Show More Authors

As cities across the world grow and the mobility of populations increases, there has also been a corresponding increase in the number of vehicles on roads. The result of this has been a proliferation of challenges for authorities with regard to road traffic management. A consequence of this has been congestion of traffic, more accidents, and pollution. Accidents are a still major cause of death, despite the development of sophisticated systems for traffic management and other technologies linked with vehicles. Hence, it is necessary that a common system for accident management is developed. For instance, traffic congestion in most urban areas can be alleviated by the real-time planning of routes. However, the designing of an efficie

Strategies For Urban Land use planning for Sustainable Urban Development
...Show More Authors

The concept of sustainability is one of the modern concepts that influenced the quality of the urban plans for the cities, through the interest in the environmental and social aspects as well as the economic aspect and the need to balance to achieve sustainable development.

The research aims to identify the most prominent methods of sustainable urban land use planning and the strategies developed within these approaches to achieve sustainable development. The research started from the problem of a knowledge gap in adopting sustainable approaches and strategies when planning urban land uses for the holy city of Karbala.
