Effect of steel fibres inhibiting flexural crack in beam / Mohd Noor Azman Yaacob
No full textReinforced concrete beam is now universally recognized as a vital component of structure members. Since the properties of concrete is good in compression but weak in tension thus experiences the cracking problem. So in order to inhibiting the flexural crack in beam, the addition of steel fibres in reinforced concrete beam has been proposed. This research conducted focus on simply supported beam to determine the effect of steel fibres inhibiting flexural crack in beam. The hooked-end steel fibres with the dimensions of 0.75 mm in diameter, 60 mm in length was used in this study. The 100 mm x 100 mm x 100 mm concrete cube was casted to determine the compressive strength in accordance to BS 1100-4 1997. It was measured for 7 days, 14 days and 28 days. The concrete cube samples included cube of plain concrete as control sample and cube of concrete contain of 25 kg/m amount dosage of steel fibres. The grade of concrete was used in this study is 30 N/mm2. Slump test for each concrete batches have measured to determine the texture of the fresh concrete and its uniformity. Four number of simply supported beam with size of beam was designed as 150 mm x 250 mm x 1000 mm were tested to determine flexural strength behaviour, two with 25 kg/m3 amount of steel fibres and another two without steel fibres. The Flexural Strength Test knows as three point bending test are carried out and data were recorded and analyzed. The results obtained from the tests are show that additional steel fibres in reinforced concrete beam contribute significantly in influence the compressive strength, increase of ultimate load, reduce deflection and thus inhibiting flexural crack in beam
The use of e-books and social media in introducing Malaysian folklores among children / Nur Izz Wildani M Noor Azman and Amirah Mohd Juned
No full textThe influence of Disney princesses' tales has pushed local Malaysian folklores to the brink of disappearance, especially among the younger generation. Thus, in an attempt to revive and retell the known and unknown folk tales to children of this generation, two different types of platform were used with the same content as to fit the children’s learning styles that are related such as visuals, auditory, and reading. The first one is an e-book containing 12 local female legends’ stories with illustrations was published digitally. In addition, an Instagram account named @onceupon.a. legend was also created in dedication to post videos to promote and tell the lores of those 12 legends. This approach could be used as a form of edutainment where the children could learn such histories and tales without feeling bored about it. In order to produce ‘Once Upon A Legend’ e-book and Instagram videos, it required detailed procedures by researching, editing, animating, writing, and finalising the outcomes of the products. Therefore, the aim of creating the e-book and videos on Instagram is to elevate the knowledge of Malaysian princesses folklores among children in Malaysia that suits with their learning preferences

Box 3030, Irbid, 22110, Jordan, Tel +96227201000-26939, Fax +96227201087, Email [email protected]: Breast cancer is a significant worldwide health issue, particularly in Jordan, where early detection via mammography is essential for effective disease management. Despite the little radiation risk associated with mammography, it is crucial to monitor radiation exposure to guarantee patient safety. This study intends to assess skin entrance exposure and compute the Mean Glandular Dose (MGD) in mammography units to determine adherence to established criteria and pinpoint areas for enhancement.Methods: To assess MGD, the study utilized the American College of Radiologists (ACR) phantom alongside a RaySafe X2 MAM dosimeter. Measurements of entrance kerma and half-value layer (HVL) were taken across 25 mammography units in Jordan. The MGD was calculated according to the ACR’s 2018 protocol, which provides a standardized approach to ensure accurate and comparable dose estimations. These measurements were then analyzed against the ACR’s threshold of 3 mGy to assess compliance.Results: The study found that the average MGD across all units was 2.3 mGy, with individual values ranging from 0.95 to 4.10 mGy. Although 67% of the units maintained MGD values within the ACR threshold, 33% exceeded the recommended limit of 3 mGy. Higher MGD values were particularly common in non-accredited facilities, where the average MGD reached 2.7 mGy, compared to 1.6 mGy in accredited units, suggesting gaps in quality control and adherence to best practices in non-accredited centers.Conclusion: This study emphasizes the critical role of accreditation and adherence to quality standards in maintaining safe and effective mammography practices. While most mammography units in Jordan meet the ACR’s recommended MGD limits, the elevated dose levels in some non-accredited facilities highlight the need for more rigorous implementation of accreditation standards. Improving compliance with established guidelines will enhance breast cancer screening effectiveness, ultimately supporting better early detection and outcomes for breast cancer in Jordan.Keywords: patient safety in cancer imaging, mammography quality assurance, mean glandular dose, healthcare accreditation, breast cancer screening, patient safety in cancer imaging, radiation dose optimization in cancer screenin
Islamic Branding and Social Media: Implications on Stay Decisions in Sharia Hotel (Survey on Guest Staying at Noor Hotel: Moeslim Boutique Hotel Bandung)

Human population, urban settlement patterns and their impact on Plasmodium falciparum malaria endemicity
No full textBackground: the efficient allocation of financial resources for malaria control and the optimal distribution of appropriate interventions require accurate information on the geographic distribution of malaria risk and of the human populations it affects. Low population densities in rural areas and high population densities in urban areas can influence malaria transmission substantially. Here, the Malaria Atlas Project (MAP) global database of Plasmodium falciparum parasite rate (PfPR) surveys, medical intelligence and contemporary population surfaces are utilized to explore these relationships and other issues involved in combining malaria risk maps with those of human population distribution in order to define populations at risk more accurately.Methods: first, an existing population surface was examined to determine if it was sufficiently detailed to be used reliably as a mask to identify areas of very low and very high population density as malaria free regions. Second, the potential of international travel and health guidelines (ITHGs) for identifying malaria free cities was examined. Third, the differences in PfPR values between surveys conducted in author-defined rural and urban areas were examined. Fourth, the ability of various global urban extent maps to reliably discriminate these author-based classifications of urban and rural in the PfPR database was investigated. Finally, the urban map that most accurately replicated the author-based classifications was analysed to examine the effects of urban classifications on PfPR values across the entire MAP database.Results: masks of zero population density excluded many non-zero PfPR surveys, indicating that the population surface was not detailed enough to define areas of zero transmission resulting from low population densities. In contrast, the ITHGs enabled the identification and mapping of 53 malaria free urban areas within endemic countries. Comparison of PfPR survey results showed significant differences between author-defined 'urban' and 'rural' designations in Africa, but not for the remainder of the malaria endemic world. The Global Rural Urban Mapping Project (GRUMP) urban extent mask proved most accurate for mapping these author-defined rural and urban locations, and further sub-divisions of urban extents into urban and peri-urban classes enabled the effects of high population densities on malaria transmission to be mapped and quantified.Conclusion: the availability of detailed, contemporary census and urban extent data for the construction of coherent and accurate global spatial population databases is often poor. These known sources of uncertainty in population surfaces and urban maps have the potential to be incorporated into future malaria burden estimates. Currently, insufficient spatial information exists globally to identify areas accurately where population density is low enough to impact upon transmission. Medical intelligence does however exist to reliably identify malaria free cities. Moreover, in Africa, urban areas that have a significant effect on malaria transmission can be mappe
A noninvasive molecular approach: exploiting species-locus-specific PCR primers in defeating numts and DNA cross-contamination of cercopithecidae
No full textThe lack of a standardized, noninvasive molecular approach to studying genetic aspects of primates has made it hard for primatologists to decode the evolutionary history of these species. Researchers must optimize their own techniques to fully exploit the available samples. Lack of species-locus-specific primers also contributes to difficulties in using noninvasive genetic samples. Thus, the objectives of this study were to develop a standardized technique to collecting samples noninvasively, propose newly designed species-locus-specific primers, and optimize conditions for polymerase chain reaction (PCR) for Macaca fascicularis, M. nemestrina, Trachypithecus cristatus, and T. obscurus. Nine new species-locus-specific primers for three different loci of mitochondrial DNA, namely D-loop, cytochrome oxidase subunit I (COI), and cytochrome b, were successfully designed. These primers proved to be efficient in amplifying larger datasets (up to ~1,000 bp) of the targeted species in the optimized PCR conditions. The species-locus-specific primers are able to anneal to host DNA alone in highly contaminated feces of highlighted species. They can also offer alternatives measures in avoiding contamination related to nuclear insertion of mitochondrial pseudogenes (numts)
