Development of Activated Carbon Fibers for Organic Removals
No full textA Master of Science thesis in Chemical Engineering by Doaa Salim Samhan Alkathiri entitled, "Development of Activated Carbon Fibers for Organic Removals," submitted in November 2017. Thesis advisor is Dr. Taleb Hassan Ibrahim and thesis co-advisor is Dr. Yehya Amin El Sayed. Soft and hard copy available.Phenols are classified to be one of the most hazardous pollutants found in wastewater. They are discharged into rivers, lakes and seas, causing adverse effects on the enviromental and human health. Adsorption is a well-known technique used to treat wastewater. Activated carbon fibers (ACFs) are highly microporous efficient adsorbents due to their small diameters, high surface area and excellent volumetric capacity. In this work, ACFs were produced using polyacrylonitrile (PAN) fibers using different methods and tools. The fibers were stabilized initially at 250°C followed by carbonization at 850°C at a heating rate of 10°C/min and under the flow of nitrogen gas at a flow rate of 135ml/min. The carbonized fibers were subjected to physical (carbon dioxide) and chemical (potassium hydroxide) activation. The results showed that chemical activation using 3:1 ratio of KOH (wt/wt) produced fibers with a higher surface area of 2885m2/g compared to the physically activated fibers (774m2/g). The synthesized ACFs (Syn-ACFs) were compared and characterized in terms of morphology, thermal stability, composition and pore characteristics using SEM, EDS, TGA, CHN and nitrogen isotherm (Quantachrome). Bench scale batch experiments were carried out to determine and compare the adsorption efficiency, optimum parameters and the capacity of Syn-ACF and commercial ACFs (C-ACFs) for p-cresol removal. The adsorption optimum conditions using Syn-ACFs are: Syn-ACFs dosage = 1 g/l, contact time = 30 minutes, temperature = 25°C and initial pH = 4.6. The adsorption study on (Syn-ACFs) gave a higher removal efficiency of 91.0% of p-cresol compared to 71.6% (C-ACFs) at a concentration of 350ppm. In addition, the adsorption isotherms of p-cresol on C-ACFs and Syn-ACFs were found to follow the Langmuir isotherm equation; however, Syn-ACFs revealed a higher adsorption capacity (500mg/g) compared to C-ACFs (294 mg/g) at 25°C. The Syn-ACFs regeneration method was evaluated thermally at elevated temperatures and chemically using ethanol and n-hexane solvents. The thermal regeneration at 600°C achieved a higher removal efficiency of 84% compared to n-hexane (78%). The Syn-ACFs were evaluated for the treatment of produced water to ensure a removal of 71.2%. The results indicated that Syn-ACFs could be used as an efficient adsorbent for p-cresol removal in wastewater.College of EngineeringDepartment of Chemical EngineeringMaster of Science in Chemical Engineering (MSChE

DENATURALIZING CULTURE: SAYED KASHUA'S NEWSPAPER COLUMNS ON THE TOPIC OF PREJUDICE
No full textAbstract Discrimination is a recurrent topic in the work of the Israeli-Arab writer Sayed Kashua. In the last couple of years, Sayed Kashua has moved away from writing about the prejudice expressed by his own Israeli Muslim community towards the Israeli Jewish population to focus his attention instead on the prejudice shown by Jews against Arabs in Israel. Self-criticism has always been a hallmark of Sayed Kashua's work so this shift indicates a significant change in the columnist's perception of his own society. Based on a survey of various issues relating to Israeli society, such as the law, the educational system and language, as well as a theoretical review of authors who observe a mutual alienation of Arabs and Jews in Israel, this article analyses several of Sayed Kashua's recent columns in the Israeli newspaper Haaretz. It also investigates how the author understands prejudice and, in a singular and surprising way, expresses his concerns and solutions to this problem

Experiencing the armed struggle : the Soweto generation and after
No full textIncludes bibliographical references (p. 354-369).This study explores the experiences of the rank-and-file soldiers of Umkhonto we Sizwe and the Azanian People's Liberation Anny. Extensive interviews by the author and other researchers reveal the voices of the soldiers themselves. The African National Congress and Pan African Congress archives at the University of the Western Cape and the University of Fort Hare supplement and verify these oral testimonies, as do some published sources. Most previously published materials about the armed struggle against apartheid have already focused on diplomacy, strategy and tactics, operations, leadership, and human rights abuses to the neglect of the soldiers' actual experiences. This study complements these with significant new oral history materials from the Soweto generation of soldiers and their successors. When dealing with MK, many authors have documented issues of the camp structure in Angola, and operations inside South Africa, so much of this detail is only addressed briefly, leaving space to explore the soldiers' experiences. In the case of APLA, very little has been written on its history, and more detail is provided on these subjects. This study therefore deals with the soldiers' politicisation and motivation for joining the armed struggle, their experiences in leaving South Africa and training in exile, the crises in exile which limited their effectiveness for a time, their return to fight in South Africa, and their difficulties in the "new" South Africa. These materials reveal that vast problems remain facing these veterans of the struggle against apartheid, and that they have the potential, if properly supported and employed, to contribute substantially to the development of present day South Africa. Conversely, if their neglect continues, they also have the potential to bring vast harm to the country. Further use of the investigative tools of oral history, especially if extended to the former soldiers' vernacular languages, is necessary to augment the history of South Africa, and these soldiers' contributions
Catha edulis chewing effects on treatment of paranoid schizophrenic patients
No full textMohamed-I Kotb El-Sayed, Hatem-K Amin Department of Biochemistry and Molecular Biology, Faculty of Pharmacy, Helwan University, Ain Helwan, Helwan, Cairo, Egypt Background: The current study’s aim is to evaluate the possible interaction effects of khat chewing on treatment of paranoid schizophrenic patients.Patients and methods: In the study group, 42 male subjects suffered from paranoid schizophrenia and were classified according to their khat chewing habits into two subgroups: either khat-chewer subgroup (SKc; n=21; r=11, h=10) or non-khat-chewer subgroup (SNKc; n=21, r=11, h=10). Each subgroup was further subdivided according to type of treatment into r (risperidone) and h (haloperidol). Healthy male subjects (37) were subdivided into healthy khat-chewer as positive controls (HKc, n=17) and healthy non-khat-chewer as negative controls (HNKc, n=20). Plasma dopamine, 3,4-dihydroxyphenylacetic acid (DOPAC), homovanillic acid, 5-hydroxytryptamine (serotonin), 5-hydroxyindoleacetic acid, epinephrine, and norepinephrine were estimated.Results: ANOVA and post hoc analysis showed that dopamine was illustrating significant elevation in all khat chewing groups. DOPAC was illustrating significant decrease in all khat chewing groups with an interesting outcome showing significant increase in DOPAC in SNKcr group due to risperidone effect. Homovanillic acid, serotonin, hydroxyindoleacetic acid, and norepinephrine were illustrating significant elevations in all khat chewing groups. Epinephrine was illustrating significant elevation in all chewers than non-chewers groups. Unexpected significant decrease in epinephrine in the SNKcr group indicated that risperidone drug is decreasing epinephrine through indirect mechanism involving calcium.Conclusion: Khat chewing in schizophrenic patients is contraindicated because it aggravates the disease symptoms, attenuates all used treatment medications, and deteriorates all biochemical markers of the patients. Keywords: epinephrine, norepinephrine, dopamine, serotonin, schizophrenia, kha
Tão dúbio, tão coerente: forma e conteúdo nas crônicas jornalísticas de Sayed Kashua
No full textEste artigo consiste na análise de duas crônicas jornalísticas do escritor árabe-israelense Sayed Kashua publicadas no jornal israelense Haaretz. Estes textos são selecionados devido à sua riqueza de conteúdo e pelo uso de estratégias retóricas, tais como a autoironia e o sarcasmo, para expor os conflitos pelos quais passa o “eu do cronista” retratado pelo autor. Este estudo tem como base os Estudos Culturais e os Novos Paradigmas Literários, ferramentas que permitem o estudo das crônicas jornalísticas como textos literários. Nestas crônicas, de uma maneira despretensiosa, partindo de experiências subjetivas e de temas familiares, com autoironia e tom satírico, Kashua reporta as experiências de um árabe israelense que vive num embate em torno de suas duplas lealdades e ideologias conflitantes, refletindo uma negociação entre sua etnicidade e sua nacionalidade. A crônica, neste contexto, é considerada o local apropriado para a escrita de Kashua: a ambiguidade do gênero é similar à necessidade de quebras de dualidades na sociedade israelense para entendermos e convivermos com o “eu do cronista” de Sayed Kashua. So dubious, so coherent: form and content in Sayed Kashua´s journalistic chronicles - Abstract: This paper consists of the literary analysis oftwo journalistic chronicles written in Hebrew by the Muslim Arab Israeli author Sayed Kashua published in the Israeli newspaper Haaretz. These texts are selected due to their richness of content and use of rhetorical strategies such as self-irony and sarcasm to expose the conflicts through which the “I of the chronicler” portrayed by the author goesthrough. This analysis will rely on theoretical assumptions of Cultural Studies and the “New literary paradigms”, tools that will enable us to study the journalistic chronicle as a literary text. In these chronicles, in a non-pretentious way, coming from the subjective experiences and family topics, with self-irony and in a satirical way, Kashua reports the experiences of an Israeli Arab who lives in a clash over his dual loyalty and conflicting ideologies, reflecting a negotiation between his ethnicity and his nationality. The chronicle, in this context, is considered the appropriate location for Kashua’s writings: the ambiguity of the literary genre is similar to the necessity of breaking dualities in Israeli society to understand and to be acquainted with the “I of the chronicler” of Sayed Kashua
Irrigated silage maize yield and water productivity response to deficit irrigation in an arid region
No full textSimulation models have proven to be useful. The AquaCrop model, which has been expanded by FAO, simulates crop yield based on the applied water under conditions of full and deficit irrigation levels. In this study, the AquaCrop model's performance was tested using data for silage maize (Zea mays L.) under full (100% fulfillment of ETc) and deficit irrigation levels (90, 80, 70, and 60% of full irrigation) in the arid and semiarid environment of central Iran in the Gavkhuni River Basin (GRB). To calibrate this model, we used physiological measurement sets of cropping seasons 2000 to 2002. AquaCrop simulated well the decrease of the biomass yield (B-yield) of silage maize in response to drought as happened in the field. B-yield was decreased by 9.9% under deficit irrigation as compared to fully irrigated conditions. The coefficient of determination (R²) for simulation of B-yield and water productivity (WP) was 0.95 and 0.99, respectively. But the R²=0.77 was not satisfactory for actual evapotranspiration (ETa). The results for all investigated parameters in the three years showed that RMSE, d, ME, CRM, and E values ranged from 0.90% to 3.85%, 0.98 to 1, 1.25% to 6.4%, -0.027 to 0.03, and 0.817 to 100%, respectively. At the end, a local second-degree polynomial crop water production function (CWPF) for silage maize is presented.Hamidreza Salemi, Mohd Amin Mohd Soom, Sayed-Farhad Mousavi, Arman Ganji, Teang Shui Lee, Mohd Kamil Yusoff, Vahid Reza Verdinejadhttp://www.pjoes.com/abstracts/2011/Vol20/No05/list.htm
