An investigation into the removal of starch paste adhesives from historical textiles by using the enzyme α-amylase

Abstract The α-amylase enzyme has been reported during the last decade to be used for removal of the excess starch adhesive paste, which is usually used to fix textiles on paper, textiles, wood panels, or other rigid support materials. The final aim of this work was the application of α-amylase in order to remove the old starch from historical textiles in an attempt to conserve them under mild conditions. An extensive study was undertaken using various types of textiles in order to identify the optimum condition for the use of the enzyme, in relation to time, concentration, temperature and pH, before any other attempt. The first step was to simulate the textile ageing. The fabrics were coated with starch paste adhesive, and then a process of artificial thermal ageing was made on samples for different periods of time. After that the enzyme was applied to the samples, at different concentrations and at different intervals. This study also presents interesting results concerning the effect of the enzymatic treatment on the mechanical and optical parameters of linen, silk and cotton, dyed with madder or turmeric dye mordanted with CuSO4 or ferric citrate. Finally, the removal of enzymatic residues from textiles after the treatment has been studied. The application section has been fulfilled by using the whole process in a piece of a historical carpet from fabric adhered with starch. This piece of carpet is in the museum of the Faculty of Applied Arts, Helwan University in Egypt.

Improving EFL majors’ critical reading skills and political awareness: A proposed translation program

Surveying the existing situation and considering the pilot study conducted by the researcher, it was clear that there is a problem concerning weaknesses in critical reading and translation skills aside from the lack of political awareness on the part of fourth year EFL majors at the Faculty of Education, Helwan University. The majority of students’ problems laid in the fact that they do not approach critical reading and translation in a systematic, strategic way. Therefore, this study examined the effectiveness of a task-based translation program with a group of fourth-year TEFL majors. Being rooted in theoretical foundations such as Decker theory of literary instruction, and Crismore's input hypotheses, the proposed program aimed at improving students’ critical reading and translation skills of expository and argumentative political texts and raising their political awareness. The results of pre- and post-intervention tests and review of written reflections by students and instructor reveal that this study project was successful in achieving its aim. Based on the results, certain recommendations are provided e.g. the relationship between translation and critical thinking/reading should be the focus in language learning. Implications and recommendations are made for similar EFL contexts.

Hepatoprotective effect of feeding celery leaves mixed with chicory leaves and barley grains to hypercholesterolemic rats.

Celery, chicory leaves, and barley grains are valuable in weight loss diets and regulate lipid metabolism. They may reduce risk of fatty liver. The present study aimed to investigate the effect of diet supplementation with celery, chicory, and barley powder on liver enzymes and blood lipids in rats fed with cholesterol-enriched diet. This study used four groups of rats fed with 3% cholesterol were supplemented diet to induce hypercholesterolemia and one group was fed on cholesterol-free basal diet. The dry powder of celery leaves, chicory leaves, and barley grains was separately added to the basal diet at 10% concentration or in combination of three plants at 15% for four weeks. Biochemical analyses of serum liver enzymes and blood lipids as well as histopathological examination of liver were performed. Feeding of diet supplemented with 10% of celery, 10% chicory, and 10% of barley lowered the elevated serum level of liver enzymes and blood lipids in rats. Feeding plant combination of celery, chicory, and barley at 15% concentration (5% from each) was more effective in decreasing the elevation of liver enzymes (aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase) and blood lipids. The histopathological lesions seen in the livers of hypercholesterolemic rats were ameliorated by feeding this plant mixture. This study recommends that dietary intake of plant mixture of celery; chicory, and barley at 15% (5% of each) concentration can be beneficial to patients suffering from hypercholesterolemia and liver diseases.

Editorial: Information technology for development

In this issue we continue the series of articles on information technology for development (ICTD) which began with the paper by Rebecca Sears and Michael Crandall in IFLA Journal Vol. 36, No. 1, March 2010. In the first of two new articles on this topic, ‘Bringing the benefits of information technology to underserved populations: An introduction to ICTD for the library community’, Christopher T. Coward of the University of Washington Information School in the USA points out that, while organizations and innovations in the ICTD community have much to offer libraries, ICTD has grown largely outside the purview of public libraries. The aim of his article is to introduce the defining features, tenets, and focus areas of ICTD, and to provide examples of how partnering with ICTD could benefit libraries. The article concludes with a discussion of the overlap with telecenters, with its attendant opportunities and risks, and other suggestions for libraries when partnering with ICTD. The second paper on the subject of ICTD, ‘Symbiotic partnerships: The global library community and the ICTD stakeholders’, is by Fay A. Austin of Rutgers University Libraries, also in the USA. The author notes that, while it may appear redundant to promote collaboration between those working in the field of information and communications technologies and librarians dedicated to providing access to information for all, the role of library and information professionals in providing access to information, in communicating the advantages of the new technologies and in educating the user population in their use was not recognized in the call to action issued by the signatories to the Millennium Development Goals. Information professionals therefore need to educate ICTD stakeholders about the expertise and experience available in the global library community. From general discussions of information and development, we turn next to a consideration of an aspect of information work in a specific developing country, and one which does not involve information and communication technologies. In ‘Main factors affecting the preservation of Chinese paper documents: A review and recommendations’, Liu Jiazhen and Wang Jingxuan of Wuhan University in China demonstrate that the priorities for the preservation of Chinese documents are protecting the documents against air pollution and controlling pests and insects. The paper proposes the creation of favourable microenvironments for decreasing the acidification of papers and the adoption of various measures for controlling pests and insects. The next paper takes us to a different region of the world. In ‘Arab online book clubs: A survey’, Amany M. Elsayed of Helwan University in Egypt reports on a study of the current situation of seven Arab online book clubs – five from Saudi Arabia and two from Egypt – and gives a comparative account of their performance. Despite low participation and superficial discussion, and lack of services provided to readers, Arab online book clubs are becoming a promising environment for promoting reading, and motivate people from all ages to contribute and exchange ideas because the clubs have the primary objective of promoting and enhancing reading. Young Arab readers have begun to discuss books in online groups, and to establish their own online clubs that work apart from librarians and publishers in Arab countries. The author provides recommendations for the improvement of Arab online book clubs. We remain in the Arab world with the final paper in this issue,’System Migration from Horizon to Symphony at King Fahd University of Petroleum and Minerals’, by Zahiruddin Khurshid and Saleh A. Al-Baridi. The paper highlights the difficulties and problems in library automation systems migration faced by libraries in the Middle East due to the lack of direct support from the systems’ parent companies. Local vendors lack the required expertise and resources I F L A

Antimicrobial Susceptibility Profile of Pseudomonas aeruginosa Isolates in Egypt

Pseudomonas aeruginosa is a leading cause of nosocomial respiratory tract, urinary tract and skin infections. Data are sparse on the antimicrobial resistance of P. aeruginosa in Egypt. We sought to detect and compare the antimicrobial susceptibility of P. aeruginosa isolates from respiratory tract, urinary tract and skin infections at 3 Egyptian hospitals. Minimum inhibitory concentrations of antibiotics were determined by the agar dilution method. P. aeruginosa respiratory tract infections isolates were 100% resistant to ampicillin, ampicillin/sulbactam, amoxicillin, amoxicillin/clavulanate and chloramphenicol, highly resistant to cefuroxime (89%), tetracycline (89%) and azithromycin (84%), and susceptible to norfloxacin (89%), amikacin (84%) and meropenem (68%). P. aeruginosa urinary tract infection isolates were 100% resistant to ampicillin, amoxicillin, chloramphenicol, cefuroxime and tetracycline, highly resistant to amoxicillin/clavulanate (95%), azithromycin (95%), cefalexin (91%) and ampicillin/sulbactam (82%), and susceptible to amikacin (82%), meropenem (73%) and norfloxacin (64%). P. aeruginosa skin infection isolates were 100% resistant to ampicillin and amoxicillin, highly resistant to tetracycline (95%), amoxicillin/clavulanate (95%), cefalexin (87%) and azithromycin (84%), and susceptible to amikacin (87%), norfloxacin (71%) and meropenem (68%). The anti-pseudomonal effect of antibiotics varied among different infection sites only for ampicillin/sulbactam, cefoperazone or chloramphenicol but not with the other tested antibiotics. Norfloxacin and amikacin could be used for initial therapy for P. aeruginosa mediated respiratory tract infections. Amikacin, meropenem and norfloxacin could be used for P. aeruginosa mediated urinary tract and skin infections. Such studies are essential to determine the current guidelines for empirical therapy regimens, which vary by location, and help with the establishment of effective infection control measures.
