    In the North Gas Company (NGC) in Kirkuk, Iraq, sour gas stream is loaded with considerable amounts of H2S and CO2 of 2.95% and 2.54%, respectively. A DEA amine system is currently used to reduce these sour component concentrations below 5 ppm and 2% for H2S and CO2, respectively. This study used Bryan Research and Engineering’s ProMax® process simulation software to optimize this amine sweetening system by adopting other amine types and blends, such as methyldiethanolamine (MDEA). It could be argued that a 50 wt% MDEA solution circulated at 414 m3/h was determined to be the optimum operating conditions. This design met sweet gas specifications and minimized the reboiler duty to 38 MW, 30.9% reduction in steam consumption. The experimental simulation work is also examined the effects of lean solvent temperature on the gas sweetening process efficiency and performance and find out that the lean amine temperature within the range of 43–48°C in all sceneries give acceptable sweetening results

    Am I different? Social identity, difference, exclusion and the (un)happiness of the black and minority ethnic child

    Get PDF
    The demographic shift in Britain over recent years is more apparent in our schools than anywhere else; with changes in racial, cultural, religious and linguistic diversity all contributing to making these schools different from what they used to be. The way that educators (in particular) respond to these changes can have significant impact on the happiness and well-being of children from these diverse backgrounds. A positive or negative response can affect the happiness, self-esteem and academic success of Black and Minority Ethnic (BME) children. It is often said that childhood is the happiest time of our lives, with happiness conceptualised as a relatively stable positive affective trait that underscores life satisfaction and subjective well-being. Children’s well-being and happiness is thus an increasingly important area of interest in practice, and especially for policy and research, with governments becoming more interested in monitoring and measuring children’s well-being to inform policy

    “Infused with multicultural education”: Teaching Preparedness for the Contemporary Classroom

    Get PDF
    There is a growing need to rethink ways to teach both Black and White pupils in multicultural and diverse societies. This paper explores the creation of teaching materials reflecting the contributions of the African diaspora undertaken by student secondary school teachers at a university in the East Midlands, UK. Consideration of the effect of this on the students’ attitudes was collected via on-line survey and the findings from this analysed thematically. Findings reflect that, given ‘permission’ and through developing an understanding of their own agency, the White students were enthusiastic about developing resources that challenge the marginalisation of Black people in their subjects. The paper emphasises the need for organisations to support students to find creative ways of teaching in diverse communities and explores how understandings and respectful representations of race need to infuse every aspect of contemporary curricula (r3)

    Extadigits: an unusual presentation

    Get PDF
    Extra digit is a common congenital anomaly in our environment which usually affect the hands and occasionally the feet but very rarely both. A five months old male infant presented with accessory digits of the both hands and feet, with two extra digits on the left hand and one on the right hand, right foot and left foot. The extra digits were well developed, with normal range of motion, good capillary refill and intact sensation. General examination revealed an otherwise healthy child with no associated congenital malformations. The treatment modality used was surgical removal of the extra digits and reconstruction of any associated anomalies in the remaining ray such as longitudinal epiphyseal bracket. After the surgery the patients is no longer experience difficulty with fitting gloves and shoes as well as discrimination among peer groups in his future life

    Spectrophotometric Determination of Mycophenolate Mofetil as Its Charge-Transfer Complexes with Two π-Acceptors

    Get PDF
    Two simple, selective, and rapid spectrophotometric methods are described for the determination of mycophenolate mofetil (MPM) in pure form and in tablets. Both methods are based on charge-transfer complexation reaction of MPM with p-chloranilic acid (p-CA) or 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) in dioxane-acetonitrile medium resulting in coloured product measurable at 520 nm (p-CA) or 580 nm (DDQ). Beer's law is obeyed over the concentration ranges of 40–400 and 12–120 μg mL−1 MPM for p-CA and DDQ, respectively, with correlation coefficients (r) of 0.9995 and 0.9947. The apparent molar absorptivity values are calculated to be 1.06 × 103 and 3.87 × 103 L mol−1 cm−1, respectively, and the corresponding Sandell's sensitivities are 0.4106 and 0.1119 μg cm−1. The limits of detection (LOD) and quantification (LOQ) are also reported for both methods. The described methods were successfully applied to the determination of MPM in tablets. Statistical comparison of the results with those of the reference method showed excellent agreement. No interference was observed from the common excipients present in tablets. Both methods were validated statistically for accuracy and precision. The accuracy and reliability of the methods were further ascertained by recovery studies via standard addition procedure

    Biofuel From Cow Tallow: A Case Study

    Get PDF
    The global demand for energy in recent decade has been dramatic. Indeed, several oil and gas reservoirs around the world are depleted every day. Moreover, the fossil fuels for example, petroleum emitted huge quantities of toxic gases to the environment. Therefore, the passive environmental consequences of fossil fuels and the bother about fossil fuel supplies have encouraged the investigation for renewable biofuels. Thus, this work is objective to produce a biodiesel fuel from residual cow tallow that produced every day at Koya city slaughterhouse. The Koya slaughterhouse cow tallow may consider low cost renewable feed stock to produce biodiesel. Furthermore, the study has examined various process parameters for example, catalyst amount and alcohol amount as well on fuel production yield. The produced biodiesel is also subjected into several tests for instance, density and cetane number

    Revisiting (inclusive) education in the postcolony

    Get PDF
    Abstract: This article uses a dialogic approach to explore the complex state of education in the postcolony. It revisits the subject of educational inclusion (and exclusion) and interrogates different epistemological and systemic framings of what constitutes education and knowledge, and the effects that these have on the postcolonial educa- tional landscape. The authors ask troubling questions of the ways that the largely Eurocentric conceptualisations of these issues, and the baggage of colonial(ism/ity) can and do affect the design and delivery of education in these settings. The use of a metalogue as a methodological approach allows the contributors to jointly ponder the issues from different perspectives and positionalities, and in a way that honours their individual voices

    Prescribing patterns of gastrointestinal drugs in private clinics in Benghazi-Libya

    Get PDF
    Background: Prescription analysis can pinpoint areas of improvement in encounters issued by prescribing physicians. The present study was carried out to analyze prescribing trends for outpatients among consultants in the city of Benghazi-Libya.Methods: A total of 4000 prescriptions were collected from private pharmacies around the city of Benghazi, Libya. Indicators addressed included the patient's name, age, sex, and address, and the physician's name, address, and signature. The percentage of prescriptions lacking this information was calculated. Drugs prescribed by dosage, duration of treatment were also considered. The study focused on the commonly prescribed classes of gastrointestinal drugs and the most frequently prescribed drug of each common class. No attempt was made to evaluate the incidence of various gastrointestinal disorders. Results are expressed as frequency and percentage of prescribed medicines.Results: Information present in prescriptions and pertaining to the patient were name (2972, 74.3%), age (468, 11.7%), date of visit (107, 2.7%) while those for prescriber were name (1902, 47.6%) and signature (3612, 90.3%). None of the prescriptions contained sex of patient, his/her address, or registration number of the prescriber. All prescribed drugs were in brand names. Polypharmacy was not evident as all prescriptions contained 1-2 drugs.The number of prescriptions with a gastrointestinal drug(s) counted to 421 (10.5%) out of the total 4000 prescriptions. The most commonly prescribed classes of gastrointestinal drugs include in order, anti-hyperacidity, anti-emetics, anti-spasmodic, laxatives and anti-diarrheal with the most frequently prescribed drug of each therapeutic class being omeprazole (67, 48.9%), metoclopramide (57, 57%), hyoscine-N-butyl bromide (42, 55.3%), bisacodyl (44, 59.5%) and loperamide (30, 88.3%) respectively.Conclusions: The results of the present study indicate the need to improve prescribing among physicians, a task that can be achieved through inclusion of related topics such as prescription writing and rational drug use in undergraduate curricula and continuing medical educational programs
