Preparation And Characterization of Adsorbent From Leather Off-Cuts: A Potential Wastewater Decontaminant: Characterization of leather offcuts
No full textThe preparation and characterization of Adsorbent from leather off-cuts was prepared by cutting the off-cuts and then pulverize into powder using grinding. The treatment which was used to characterized the leather off-cuts in NaOH, EDTA, and H2SO4 at different molarity, subsequent characterization using FTIR was done. The result obtained varies at different molarity treatment. The NaOH treatment shows a progressive reduction to amine absorption of dechroming frequencies of 3254.61 CM-1, 3247.20 CM-1, 2917.61 CM-1, 2918.30 CM-1, 2917.63 CM-1 correspond to 0.2M, 0.4M, 0.6M, 0,8M, and 1.0M respectively. For H2SO4 , a similar trend was observed with a little fluctuation in the absorption band. For EDTA, the absorption from 3525.91 CM-1 , 3366.53 CM-1, 3522.24 CM-1 and 3517.45 CM-1 respectively was observed
School Principals’ Attitudes and Level of Technology Integration in Moroccan Public Schools
No full textThis study investigates the relationship between school principals’ attitudes and the impact this has on the level of technology integration in Moroccan public schools. Data were collected by surveying 167 school principals via two different instruments. The computer attitude scale (CAS) (Gressard and Loyd, 1986) measures attitude toward computers and computer use and the level of technology integration (LoTi) Moersch (1999) measures the various levels of technology integration. Findings suggest that there is a negative correlation between school principals’ attitudes and their level of technology integration at the Computer Attitude Scale (CAS) with (r = -.32, n = 167, p< .0005) and at the four sub-scales as well. The results obtained at this level accentuate another negative correlation existing between Computer confidence with (r = -.23, n = 167, p < .0005), computer liking (r = - .40, n = 166, p< .0005), computer usefulness (r = - .25, n = 167, p < .0005) and finally, computer anxiety with (r = - .08, n = 167, p < 0005) and level of technology integration. Recommendations for research and practice are provided.  
Haar wavelet approach to study the control of biological pest model in Tea plants
Get PDFn this study, we consider a novel approach called the Haar wavelet collocation method (HWCM) toexamine the mathematical model of pest propagation in tea plants and how biological enemies might controlthem. This model is in the form of a system of coupled ordinary differential equations (ODEs). When studyingthe system, we consider tea plants, pests that harm the plants, biological enemies that are their reasonablecompetitors of pests, self-reproduction of the tea plants, natural death of pests and natural enemies, etc. Byturning the Mathematical model into a system of non-linear algebraic equations, we use the properties ofthe Haar wavelets. The opted method can solve the biological pest management problem in tea plants. Thevalues of the unknown coefficients are recovered using the collocation method and Newton Raphson method.The Mathematica program acquires the numerical results, nature, and uniformity. The acquired findings showthat the current method is more accurate than those indicated in tables and graphs
A Critical Discourse Study of Shakespeare’s Theological Conceptions in Acts IV and V of Richard II: The ‘Divine Mandate’ of Richard Kingship Falls Apart
Get PDFThis article studies the rebellious Shakespeare’s politico-religious discourse in the Renaissance England. An appropriated interdisciplinary blend of Critical Discourse Analysis (henceforth CDA) is employed to lay bare the discursive strategies appropriated by William Shakespeare to safely express his pragmatic philosophy of politics and religiosity in Acts 4 and 5 of Richard II. This study attempts to bring together linguistic, sociocognitive, and critical metaphorical aspects in one single CDA framework. Serving methods and tools of analysis from various well-known CDA approaches such as Fairclough (1989 and 1995), Van Dijk (1993 and 2001), and the Critical Metaphor Analysis (henceforth CMA) model (e.g., Lakoff and Johnson, 1980) are selected to fulfil the aims of analysis. The horrendous fate of King Richard II is an exemplar that evidently embodies Shakespeare’s preach of political pragmatism against a deep-rooted holistic system of politico-religious justified by alleged divine regencies
Mathematical Analysis of Drugs and Substance Abuse in Kenya among the Adolescents
Get PDFIt is incontestable that the mortality rate among drugs and substance abusers is higher than that in thegeneral population. The National Authority for the campaign against alcohol and substance abuse (NACADA)has painted a grim picture of the incessant rise in the number of youth becoming addicted. In this research, adeterministic model for drugs and substance abuse (DSA) driven by light drug abusers (LDA) and heavy drugabusers (HDA) was proposed. The basic reproduction number R0; , the foundation upon which the model’sstability analysis is established, was determined by utilizing the next-generation matrix (NGM) approach.The analysis showed that drug-free equilibrium (DFE) is locally asymptotically stable for R0 < 1 and unstableif R0 > 1. The global stability of both DFE and drugs endemic equilibrium (DEE) are explored by utilizingLyapunov functions. The bifurcation analysis was carried out using the center manifold theorem, where themethod utilized by Castilo-Chavez and Song was implemented and revealed that the rate of drug reinitiationdrove backward bifurcation. The contribution of the important parameters to DSA are investigated, andresults are presented graphically. Results from the simulation revealed that delayed exposure of the youth todrugs increased identification and treatment of the LDA and HDA, which would curtail DSA menace in Kenya
Investigating the Iranian Translators’ Subtitling and Dubbing Strategies in Translation of Allusions in the Animated Movies from English into Persian
No full textThe allusions are cultural terms and the translation of them in AVT is a difficult task for translators, especially in distant cultures such as English and Iranian. Because, the translators needed to be analyzed allusions according to the ıts type and the categorization to which they belong. The present study aimed to identify the allusions, in particular PNs and KPs, based on Leppihalme’s (1997) classification model in animated movies. It tried to investigate Iranian translators’ strategies for subtitling and dubbing the allusions in four animated movies including Mr. Peabody and Sherman (2014), Shrek 2 (2004), Rio (2011), and The Simpsons (2007) based on Leppihalme’s (1997) model and to determine the differences between the strategies used in the dubbing and subtitling of the allusions. For this purpose, the researcher adopted a quantitative method with a comparative descriptive approach. Then, the mentioned animated movies were examined to collect and classify allusive elements. After analysis, the results showed that there were found 60 allusions including 30 KP and 30 PN based on Leppihalme’s (1997) taxonomy. As well as, the findings of strategies analysis related to subtitling indicated that the Retention Name and Literal Translation were the first and second most frequent strategies with 38.3% and 36.7% respectively. While Omission was the least frequent strategy with 3.3%. Furthermore, the findings of strategies analysis related to dubbing illustrated that the Omission name was the first and most frequent with 21.7% while Recreation was the least frequent strategy with 1.7%. The findings of this study can provide a pedagogical implication for translation students so that they can recognize the translations of allusions with subtitling and dubbing strategies and can be utilized as a guideline for fans in the subtitling and dubbing industry
Is 50% of Arabic Enough to Teach English? The Problematic Use of Translation in the 21st Century Moroccan English Classroom
Get PDFOne of the perennial controversies in an EFL/ ESL classroom is whether to use or not to use translation in bi/ multilingual contexts. And here, I am referring to the use of Modern Standard Arabic (MSA)/ Moroccan dialect (Darija), Amazigh, or French in the Moroccan English classroom. To understand the complexity of this inter-lingual aspect, this paper aims at verifying the impact of using translation on the learning process of bilingual/ multilingual learners of English. It espouses the contention that the use of the existing linguistic repertoire is cognitively and practically unavoidable, especially in a mobile digital era. For assessing the credibility of this claim, a mixed methods approach is chosen to weigh out the adoption or rejection of using translation in foreign language learning and teaching. 52 middle and high school teachers were randomly selected to investigate the amount of translation used to teach English in their classes, and how it affects the students’ acquisition of this language. Through classroom observations, unstructured interviews, and a questionnaire, the data were collected to measure the consistence of an inter-language phenomenon that has kept haunting EFL/ESL theoreticians and practitioners alike. The findings show that more than half of the instructors favor the moderate use of translation in their teaching. By taking into consideration the learning experience of the teacher, the age of the learners, and the motivation factors that correspond with the rising of the mobile and communication technologies available, the need to use translation is seen as inescapable. Hence, it is calling for a judicious adoption that would prioritize the fulfillment of communicative, cross-linguistic, and cross-cultural competencies in foreign language learning
Isolation of Peroxidase from Watermelon Rinds Using Three Phase Partitioning
Get PDFBackground and Objective: Peroxidase is an oxidoreductase that uses different compounds as substrate and thus can be utilized for different applications. The goal of this work is to isolate peroxidase from watermelon rinds using three phase portioning (TPP).
Methods: TPP was set by adding varying amounts of salts and alcohol and the enzyme activity recovery was measured for each variable. Different parameters were optimized successively in order to achieve the highest enzyme activity recovery including salt type, salt concentration, pH, alcohol/crude extract ratio and type of alcohol and then, combining all optimized conditions together.
Results: Salt that gave maximal recovery was sodium potassium tartarate, optimal salt concentration was 17%, optimal pH was 8, optimal alcohol/crude extract ratio was 2 and 1-butanol was preferred to t-butanol. Efficiently, upon combining all optimized factors, activity recovery of 116% was obtained
Innovative Pathways to Proficient Writing: Examining Exploratory Practice's Effects
Get PDFThis article addresses the prevalent issue of deficient writing proficiency at the university level by introducing the impact of an innovative intervention known as the Exploratory Practice (EP). This experimental study was conducted in a Lebanese university to assess the impact of EP on enhancing students’ writing skills. The research involved an experimental group and a control group. Quantitative data were extracted from students' writing drafts, pre and post study, to gauge the effectiveness of the EP intervention. The findings demonstrated a significant enhancement in writing proficiency within the experimental group. This outcome underscores the potential efficacy of EP as a dynamic pedagogical tool for improving writing skills. Therefore, this study advocates for the strategic incorporation of EP, including its foundational elements, rationale, principles, and propositions, into writing classes. The implications of this study encourage the adoption of EP to facilitate the development of proficient writing skills among students in diverse educational settings
Cultural Dimensions and Pragmatic Failure: The Case of Moroccan EFL University Students
Get PDFThis study examines the impact of cultural values on the production of three speech acts (complaints, apologies, and refusals) by Moroccan Learners of English as a Foreign Language (EFL). The study involves three groups of participants: Moroccan EFL learners (MLE), American speakers (AE), and Moroccan Arabic speakers (MA). The objective of this cross-cultural pragmatic study is to explore and identify the extent to which pragmatic failure can be attributed to the cultural value and dimensions of the learners rather than their linguistic incompetence. Participants were given Discourse Completion Task questionnaires to elicit their reactions to various situations. The results, based on Hofstede's cultural dimension framework (2010) and Hall's cultural specifications (1976), showed that culture has a significant effect on the performance of the speech acts under investigation. Findings suggested that cultural specificities do affect the pragmatic choices made by the interlocutors across the three groups of informants
