Structure design and analysis of GRP Payang boat / Muhammad Azri Faiz Roslan
No full textThe initial goal of the project was to design and analyse the structure of a GRP Payang boat. The Payang boat is a traditional wood-built boat used by fisherman. It's a boat that's been designed to fit the contour of its own body. The Payang boat was constructed using Glass Reinforced Plastic instead of wood in this project (GRP). Nonetheless, completing this project flawlessly poses numerous problems. That is due to the design of the boat frame structure, the high level of craftsmanship required, and the common usage of wood in boat construction. However, this challenge can be handled and the project's goals can be met. One of its goals is for the boat's design structure to boost its strength. Aside from that, it can successfully construct a good boat structure and ensure that the boat is stable and safe for passengers. As a result, there are phases to building a product that must be followed in order to achieve the ideal product. First and foremost, boat builders must study and learn about the boats that must be created so that they can design them using precise measurements. They can use software like PolyCad or Rhino to design the boat. They must then assess the boat's strength in order to ensure its safety. The builder will then be able to effectively design and construct the boat structure. The boat design structure will eventually be manufactured effectively. As a result of the anticipated outcome, the boat's strength can be increased by the use of GRP material and proper boat structure, resulting in a better Payang boat than previously
LPG IOT MEASUREMENT DEVICE WITH DATA ANALYTICS
No full textLPG is one of the important sources of energy for many homes and business in Malaysia. LPG is typically used as fuel in cooking equipment. For LPG owners, it is important for them to keep track of their LPG usage to ensure that their LPG does not run out when they are using it. Besides, it is also beneficial for the owners if they are notified when their LPG almost runs out.
Thus, the proposed project is to develop an IoT device to measure the LPG level and an application that can notify the owners when their LPG is running out. Moreover, the owners can check their LPG usage daily, weekly, monthly, and yearly. With this proposed project, it helps the LPG owners to plan on when to replace their LPG
High-density concrete: exploring ferro boron effects in neutron and gamma radiation shielding
No full textAimed to reduce neutron and gamma radiation, this study examined the shielding capability of high-density concretes mixed with Ferro boron in different proportions (25%, 50%, and 75%) replacing granite aggregate, denoted as 25FB, 50FB, and 75FB, respectively, with control specimen designated as CC. The concretes performance was evaluated in terms of mechanical and radiation shielding properties. Cement content, water-cement ratio, and maximum nominal size of aggregates were kept as constant. In general, workability and density reduced and enhanced, respectively, with Ferro boron increment. The increment in concrete strength was achieved with 25FB and 50FB, while 75FB mix experienced a strength reduction due to the segregation problem. Ferro boron concrete showed better radiation shielding, where 25FB, 50FB, and 75FB shielded transmission of neutron and gamma 2, 2.57, and 3.27 times as well as 1.35, 1.72, and 2.92 times, respectively, better than CC. Hence, these findings conclusively show that the increase in the Ferro boron content has progressively increased the shielding properties of the concrete, with notable caution against high inclusion of Ferro boron due to a counter-productive outcome in strength

First report of pathogenic <i>Leptospira</i> spp. isolated from urine and kidneys of naturally infected cats
No full textLeptospirosis is one of the most widespread zoonotic diseases and can infect both humans and animals worldwide. Healthy cat, as a potential source of exposure to humans, are likely underestimated owing to the lack of overt clinical signs associated with Leptospira spp. infection in this species. The aim of the study was to determine the exposure, shedding, and carrier status of leptospires in shelter cats in Malaysia by using serological, molecular, and bacteriological methods. For this study, 82 healthy cats from two shelters were sampled. The blood, urine, and kidneys were tested using the microscopic agglutination test (MAT), polymerase chain reaction (PCR), and bacterial culture. On the basis of serological, molecular, and/or culture techniques, the total detection of leptospiral infection was 29.3% (n = 24/82). Through culture techniques, 16.7% (n = 4/24) of the cats that tested positive were carriers with positive kidney cultures, and one cat was culture positive for both urine and kidney. The Leptospira spp. isolates were identified as pathogenic L. interrogans serovar Bataviae through serological and molecular methods. Through serological techniques, 87.5% (n = 21/24) had positive antibody titers (100–1600) and most of the Bataviae serogroup (n = 19/21). Using PCR, 16.7% (n = 4/24) of cats were shown to have pathogenic Leptospira spp. DNA in their urine. Furthermore, three out of four culture positive cats were serology negative. The present study reports the first retrieval of pathogenic leptospires from urine and kidneys obtained from naturally infected cats. The results provide evidence of the potential role of naturally infected cats in the transmission of leptospires. Additionally, leptospiral infection occurs sub-clinically in cats. The culture isolation provides evidence that healthy cats could be reservoirs of leptospiral infection, and this information may promote the development of disease prevention strategies for the cat population.</div
Side-Scan Sonar Coupled with Scuba Diving Observation for Enhanced Monitoring of Benthic Artificial Reefs along the Coast of Terengganu, Peninsular Malaysia
No full textSince the 1970s, artificial reef (AR) deployment has been one of the common approaches to augment the local production of coastal fish in Malaysia. However, there is a lack of strategy to assess and evaluate the success of pre-deployed AR. Realizing the need for an effective qualitative and quantitative monitoring and evaluation of AR, this study proposes side-scan sonar coupled with scuba diving observation for the enhanced monitoring of pre-deployed Bioceramic Korean (BK) AR along the coast of Terengganu, Peninsular Malaysia. This method employs an integrated side-scan sonar with a data acquisition system for the detection of the precise location of the BK AR which were deployed at Tukun Telaga Batin off the Terengganu coastline in 2003 by the Fisheries Development Authority of Malaysia (FDAM). Following the determination of the exact location of three BK AR areas, a scuba diving team was sent to survey the physical conditions of the AR and assess the feasibility of the AR as an artificial habitat for marine life. The scan sonar images were compared with the captured photographs and videos acquired during the scuba diving session for a comprehensive value-added assessment. The collected data from the scuba diving session were also processed to measure the fish diversity, the fish biomass, and identify the fish community surrounding the AR. Based on the results, the BK AR remained in extremely good condition, physically intact, without significant breakage or damage, and with no major subsidence into the sediment after 19 years of deployment. A total of 108 BK AR modules were detected in three large groups using the mosaicked sonar images. Following cross-examination to validate the AR measurements using the AR’s shadows on the seafloor, the height of the BK AR consistently ranged from 1.7 m to 1.8 m. In addition, 34 species of fish from 14 families and 26 genera were identified, with most species classified as reef-associated (RA) fish with a biomass value of 1173.31 ± 1136.69 kg m−3, indicating the successfulness of the BK AR as fish-aggregating devices (FADs). The growth of hard corals on top of the bioceramic plate of the AR module further supported the diversified community of marine life surrounding the BK AR. In conclusion, the side-scan sonar coupled with scuba diving observation demonstrates an effective qualitative and quantitative technique for the monitoring and evaluation of pre-deployed AR. This strategy is recommended to be utilized to determine the success of pre-deployment AR

Serological detection of anti-leptospira antibodies among animal caretakers, dogs and cats housed in animal shelters in Peninsula Malaysia
No full textLeptospirosis is a worldwide zoonotic disease caused by Leptospira spp. and it has emerged as one of the major public health issues worldwide. Despite extensive studies, information regarding leptospirosis in animal shelters in Malaysia is still scarce. The aim of this study was to determine anti-Leptospira antibodies and the most common circulating serogroups among humans and animals in animal shelters in west and south parts of Peninsular Malaysia. Blood samples were obtained from 58 humans, 127 dogs, and 47 cats, that were recruited from two shelters. All humans and dogs appeared healthy, except few cats showed clinical signs of mild feline upper respiratory disease. Microscopic Agglutination Test (MAT) was used to detect anti-Leptospira antibodies against 20 pathogenic serovars. Based on the cut-off antibody titre ≥ 1:100, the sero-detection of Leptospira spp. in human, dogs, and cats were as 8.62%, 20.47%, and 14.89%, respectively. Serogroup Bataviae was found in human, dogs and cats, whereas Bataviae, Javanica, and Ballum were the common serogroups among dogs and cats. Anti-Leptospira antibodies titres were in the range from 1:100 to 1:200 in human and 1:100 to 1:400 in sheltered animals. Sero-detection studies of anti-Leptospira antibodies in shelters environment worldwide and regionally is necessary to increase the public health awareness and to understand the risk of this zoonotic disease. Furthermore, data regarding the predominant serogroups is needed in a local setting for further vaccination development studies. More studies are warranted to investigate the role of sheltered animals in leptospiral transmission in its environment
