    The aim of this study was to investigate the relationship between the effects of rainfall intensity and aggregate sizes on sediment concentration and hydraulic parameters. Flow velocity, flow width, shear stress and stream power are the hydraulic parameters. The impact of various rainfall intensities with differing aggregate sizes (D1.18 mm and D2.00 mm) was also studied. Under the rainfall simulator, the different aggregate sizes, D1.18 mm and D2.00 mm, were set up at a slope angle of 20o. The flow of runoff was collected for 2 hours at several intervals (30, 60, 90 and 120 min). Then, the hydraulic parameters and concentration of the sediment were measured. As a result, the increased rate of rainfall creates a higher concentration of sediment on a steep slope from 7.988 to 3233.569 gm-3 and 2.954 to 976.736 gm- 3 for aggregate sizes D1.18 mm and D2.00 mm, respectively. Generally, as the flow depth and shear stress were reduced, the estimated sediment concentration was higher. On the other hand, flow velocity and unit stream power were directly related to the sediment concentrations.

    Current military supply chain management is complex and complicated. Activities such as information, and knowledge sharing among involved parties are prone to cybercriminal. Protection of such private and confidential documents are very important. Therefore, a military supply chain derives a critical need for decentralized and digitize transactions in the ledger. This study is proposing a new traceability chain algorithm for military shipment using blockchain. The development of this traceability chain algorithm is based on algorithm development methodology. The new traceability chain algorithm is expected to trace product movement along with the blockchain network. In addition, it is also believed that this study will provide positive results for defense shipment. Future work is to broaden the scope to other military areas such as threat intelligence.

    Tin-lead (SnPb) alloys are widely used in microelectronic packaging industry. It serves as a connector that provide the conductive path needed to achieve the connection from one circuit element to another circuit element. In this research, the effect of gamma irradiation on the micromechanical behaviour of tin-lead (SnPb) solder alloy has been investigated using the nano-indentation testing. Gamma radiation with a Cobalt-60 source were exposed to SnPb solders with different doses from 5 Gy to 500 Gy. In this study, the nano-indentation technique was used to understand the evolution of micromechanical properties (hardness and reduced modulus) of SnPb solder joints subjected to gamma irradiation. The results showed that the hardness of the SnPb alloys was enhanced with increasing of gamma radiation. The hardness was greatest at dose of 500 Gy of sample, 25.6 MPa and had the lowest value at un-irradiated sample. However, the reduced modulus was decreased by increasing the irradiation of gamma due to the intrinsic properties and the atomic bonding of the material.

    Unmanned Aerial Vehicle (UAV) as data acquisition tools are becoming more affordable for many civil engineering applications. However, the accuracy of the output is influenced by many parameters. The main objective of this study was to investigate the effect of flight altitude toward the final output measurement accuracy without using Ground Control Point (GCP). Altitude is a parameter that is very important in flying UAV that has to be taken into consideration. Notably, the flight altitude depends on the ground condition, surrounding obstruction, Ground Sample Distance (GSD) and camera monitoring. The UAV should fly in a lower condition when GSD is better. However, this approach rarely can succeed because different site conditions such as flat terrain nor hilly terrain required different flight planning. Therefore, a field experiment will be carried out to investigate the optimum flight altitude to obtain acceptable accuracy of orthomap at hilly type of terrain. This study evaluates both the qualitative of the image and the quantitative aspect of the orthomap. The actual measurement of selected features was made and compared with the on screen measurement. An orthophoto will be generated by using Pix4Dmapper on a selected slope of the hilly terrain in UPNM Campus. Based on the results, different accuracy obtain on flat surface is 0.14% and slope surface is 2.77%, which needed further study to identify the method to reduce error. It is found that the accuracy without GCP is not having large error of more than 1% for flat area. Due to distortion of image on slope surface, the error is larger and needed GCP calibration. This study shows that UAV is a feasible platform for mapping of small area with acceptable accuracy.

    Human detection and localization is one of the importance aspects in computer vision. It has broad applications in surveillance, robotic, driver assistance system, and for the military applications. The task is difficult because it depends on various conditions such as illumination, distance, human pose and weather condition. This study aimed to investigate human detection methods for thermal and visible images. We have explored three methods which are histogram of oriented gradient, integral image and aggregate of channel features. Our result showed that histogram of oriented gradient outperformed the other two using the tested images. However, the method is only applicable when the human is on the standing or upright position and limited to a certain distance between the scene and the camera position.

    The location of Sarawak State in the equatorial region makes it an area of high rainfall. For this reason, hydroelectric power plants have been built in several catchments in Sarawak, especially in the Kapit area. This needs to be harnessed to improve the economy and social living standards of the people of Sarawak in particular. This paper presents the land cover change by analyzing the stratification change for 30 years (1985-2018) at Bakun Dam, Sarawak. This study uses Landsat 5 and Landsat 8 satellite data. Both data have to go through pre-processing such as geometric, radiometric, and atmospheric corrections. In this study, Normalized Water Difference Index (NDWI) is used to classify water areas, built human areas, and vegetation areas. Overlay analysis was applied to identify areas that had changed over the 30 years in the study area. The results showed the greatest changes from vegetation areas to water bodies for 30 years. The results showed that the most affected land cover was forest cover with a reduction of 740 km², which shifted mainly to water bodies with 669.9 km² and human development with an area of 68.7 km². The study area is less populated and anthropogenic influences are rather low, but deforestation is observed in the upper river basin. These events would change the hydrological behavior of these catchments in the future. Land cover mapping is very important to provide information to those responsible for planning sustainable development. In addition, land cover maps are important for land use planning and land use regulation to avoid land-use conflicts.

    Solar panel is one of the renewable energy that can reduce the environmental pollution and have a wide potential of application. The exact solar prediction module will give a big impact on the management of solar power plants and the design of solar energy systems. This paper attempts to find the best Artificial Neural Network (ANN) based logsig transfer function and various training algorithm that can be used to calculate the temperature module (Tm) in Malaysia. This can be done by simulating the collected data of four weather variables which are the ambient temperature (Ta), local wind speed (Vw), solar radiation flux (Gt) and the relative humidity (Rh) into the Neural Network Tool in MATLAB. Three different ANN transfer function and 14 types of training were compared to choose the best method. Finally, an equation for the ANN model will be generated in order to calculate the temperature module based on ambient temperature, local wind speed, solar radiation and relative humidity variables.

    ABSTRACT
    Kuala Langat South Forest Reserve (KLSFR) was the main highlight when Selangor State
    Agriculture Corporation proposed to acquire the whole of KLSFR (about 6,908 ha) for the
    establishment of oil palm plantations. Many parties expressed their concern and opposed the plan
    as it would lead to the destruction of the forest and its biodiversity. As such, this study was aimed
    to determine the forest structure and tree species composition to conserve and sustainably manage
    the forest. Seven plots of 40 m x 20 m covering 0.56 ha were established randomly in KLSFR. All
    trees with 5 cm diameter breast height (DBH) and above were tagged, measured and identified.
    Voucher specimens were then taken for further verification purposes. The floristic composition of
    KLSFR consists of 335 individuals represented by 47 tree species from 21 families. Annonaceae,
    Guttiferaceae and Myristicaceae were the most speciose families with five species recorded for
    each family. Goniothalamus malayanus and Koompassia malaccensis were considered to have
    absolute dominance at the study site with Important Value index of 14.73 % and 14.19 %,
    respectively. KLSFR recorded low Shannon-Weiner Diversity index of H’ = 2.85 (H’max = 3.81)
    and Margalef’s Richness Index with DMG = 7.91. Evenness (E) index of 0.75 portrayed that the
    tree species are almost equally abundant in the study area. Total trees biomass was estimated at
    406.90 t/ha, represented by 349.61 t/ha of above ground biomass (AGB) and 57.29 t/ha of below
    ground biomass (BGB). The study indicated that KLSFR has uniform distribution of individuals
    with mixed species composition of trees. Tree distribution showed the pattern of De iocourt’s
    factor procedure (inverse J distribution) where number of tree decreases with the increase in
    diameter, representing the natural regeneration of the forest

    Life Sciences, Medicine and Biomedicine was established in 2017 as an open access, multidisciplinary, peer-reviewed journal. The journal welcomes submissions in all areas of life sciences, medicine and biomedicine with a selection of relevant biological sciences on a case by case basis. It is expected that the wide scope of the journal will promote multidisciplinary collaboration and attract research papers from diverse scientific settings. To put things into perspective, the first issue was published at the end of 2017, with four issues per year through 2018 and 2019 respectively. In 2020, the publication frequency was changed to a single issue annually, adopting to the continuous publication model practiced by many others. Manuscripts are processed for peer-review, and published as they are accepted throughout the year. This method has helped the editorial office to streamline the editorial process. Accepted articles are prepared for publication more robustly and in a timely manner. Based on this experience, the current model of continuous publication will be maintained. In addition to research and review articles, the journal also accepts submissions for mini reviews, opinion pieces and case reports.

    For the upcoming Volume 6 Issue 1 which will be accepting articles throughout 2022, the journal will be implementing a number of changes to the submission and editorial process. One area currently being improved is the mechanism to allow authors to submit manuscripts with very minimal formatting. Based on the feedback received from our authors, this will significantly reduce the time taken for new submissions to go through initial quality checks and approval, so that the peer-review process can commence as soon as possible. The new author’s guide will be updated and implemented in September 2021. Taking into account the global pandemic, the article processing charges for accepted manuscripts are waived throughout 2021. Further discussions are currently being held to provide financial assistance for future article processing charges for authors that may require them.

    Despite the challenging period the world is currently facing, the growth of the journal continues. The journal attributes this achievements to the scholarly contributions of the authors, reviewers and editors. During this similar period, the journal received successful approval for indexing with the Directory of Open Access Journals (DOAJ) and Scilit. It is also indexed in MyJurnal (Citation and Infometric Division of the Ministry of Higher Education, Malaysia). Editorial good practices will continue to be enhanced based on industry standards to ensure the journal attracts high quality scientific work. Preparation is also in progress for indexing with other major indexing organizations, which will assist authors and articles to reach a wider global audience.

    While the journal was initially established for the Malaysian scientific community, the current focus is for authorship and readership coverage to reach as widely as possible within the South East Asian and Asian regions. With this in mind, the expansion of the editorial board members now include experts from Malaysia, Philippines and Hong Kong. Additional editorial roles are currently being explored to complement the multidisciplinary scope of the journal, with plans for each field of research to spearhead its own section. For the journal to reach a wider global scientific community, the International Advisory Board consisting of experts from Singapore, UK, Japan, Bangladesh, China, Iraq, Philippines and Malaysia was recently established. The advisory board will provide feedback on current strategies and future direction for the international expansion of the journal, establishing good practices and will submit an annual assessment for continuous quality improvement.

    It is equally exciting to announce that the journal will publish a special issue this year for the Asian Conference on Biomedical Research and Laboratory Medicine 2021 organized by the Malaysian Association of Clinical Biochemist in collaboration with Malaysian Association of Biomedical Sciences and Association of Scientific Officers of the Ministry of Health, Malaysia from the 24-26 August 2021.

    Over the past few decades, microplastics have become increasingly ubiquitous in the environment and now contaminate the bodies of many living organisms, including humans. Microplastics, as defined here, are plastics within the size range 0.1 μm and 5 mm and are a worrying form of pollution due to public health concerns. This mini-review aims to summarise the route of entry of microplastics into humans and explore the potential detrimental health effects of microplastics. Trophic transfer is an important pathway for microplastic to be transferred across different groups of organisms, with ingestion is regarded as one of the major routes of exposure for humans. Other pathways include inhalation and dermal contact. The health consequences of microplastics manifest because these materials can translocate into the circulatory system and accumulate in the lungs, liver, kidney, and even brain, regardless of the route of entry. Health effects include gastrointestinal disturbances such as inflammation and gut microbiota disruption, respiratory conditions, neurotoxicity and potential cancers. Overall, while it is apparent that microplastics are causing adverse effects on different biological groups and ecosystems, current research is largely focused on marine organisms and aquaculture. Therefore, more studies are needed to investigate specific effects in mammalian cells and tissues, with more long-term epidemiological studies needed on human population considered to be at high-risk due to socioeconomic or other circumstance. Knowledge of the toxicity and long-term health impacts of microplastics is currently limited and requires urgent attention.

    Background: Sudden death (SD) is defined as an unexpected natural death within an hour onset of symptoms or unwitnessed death that occurs within 24 hours, which accounts for most cardiovascular deaths in Malaysia. This study aimed to evaluate the extent of histopathological changes in the heart and to study the demographic trend in SD cases in Kuala Lumpur, Malaysia. Methods: Specimens from all SD cases were received from 2017 to 2018 by the Forensic Unit, Hospital Canselor Tuanku Mukhriz (HCTM) were studied. The specimens were the left ventricular myocardium and left anterior descending artery (LAD), which were fixed in 10% formalin with haematoxylin and eosin staining. The tissues were graded histologically based on changes such as arterial occlusion, myocardial infarction, and/or thrombus formation. Results: Out of 545 medicolegal deaths, only 25 cases (4.6%) had samples available for analysis. Among these 25 patients, 24 (96%) were male patients and only one (4%) was a female patient. The available samples were from patients aged between 30 to 79 years old. In terms of ethinicity, Malays (40%) were the most numerous, followed by patients of Chinese and Indian ethnicities.The majority of the SD cases had a body mass index (BMI) that ranged between underweight (56%) and obese (40%). Besides, there were 10 (40%) cases of coronary artery with atheroma and 15 (60%) cases of myocardial infarction. The most common presentation of atherosclerosis was grade III and IV, and acute MI was the most common presentation at death, followed by healed infarcts and old infarcts. Discussion and Conclusion: Our findings reflect worsening risk factor levels in cardiovascular diseases, compounded by demographic trends. Further studies on biomarkers specific for cardiac diseases are warranted to understand imminent sudden cardiac death.

    Background: Bacteria such as the Salmonella species had been extensively studied not only for its mechanism of pathogenicity, but for its beneficial utilisation in bacterial-mediated tumour therapy. Genetically modified bacterial strain, BDLA Salmonella Agona (BDLA S. Agona) had shown great promise as tumour targeting and suppressing agent. By, constructing green fluorescent protein (GFP) expressing of this strain, it would be beneficial as it could be used to further study the interaction of the BDLA S. Agona strain with various cancerous cells and the host at the systemic level. However, GFP plasmid-induced strains may exhibit growth defects, and this was investigated in this study. Methods: The GFP-transformed Salmonella strains were constructed, and the replication rate of the strains were investigated using the BacterioScan™ 216R instrument. The replication rate between the strains was compared from the 24-hour data collected and analysed as growth curves. The 24-hour growth curves were constructed using the Log CFU/mL and OD650 data collected by the instrument. Results: It was observed from the growth curves that the transformation of the GFP plasmid into different Salmonella strains did not affect the replication rate of the bacteria. Discussion and Conclusion: This finding answers the objective of the study, and it was concluded that incorporation of the GFP plasmid does not cause any negative effect on bacterial growth. GFP-transformed Salmonella, specifically the BDLA S. Agona strain, could be utilised as a powerful tool for future studies on the mechanism of tumour suppression and real-time in vivo biodistribution of the strain.

    Background: Over the years, global salt intake has increased and has resulted in the escalation of cardiovascular diseases and hypertension. The lack of knowledge, as well as poor attitude and practice, are the main reasons that have led to high salt intake. Therefore, this study aims to evaluate the knowledge, attitude and practice (KAP) towards salt intake and health among non-academic staff of the Faculty of Health Sciences (FSK), Universiti Kebangsaan Malaysia (UKM). Methodology: This cross-sectional study was conducted among the non-academic staff of the Faculty of Health Sciences (FSK), Universiti Kebangsaan Malaysia (UKM). The respondents were recruited using stratified random sampling technique with an informed consent. A validated questionnaire to test the knowledge, attitude and practice (KAP) towards salt intake and health by the Ministry of Health Malaysia was converted into a Google form and the link was emailed to 118 participants. A total of 33 responses were obtained for evaluation. The significant values were set as P < 0.05. Results: It was observed that female participants had better attitudes towards salt intake and health compared to males (p = 0.044). Also, individuals with higher education levels had better attitudes towards salt intake and health, compared to those with lower education levels (p=0.009). However, knowledge and practice of salt intake and health bore no significant results when considering gender, education level and age. Discussion and Conclusion: Overall, this study has identified sociodemographic characteristics as contributing factors towards individuals’ attitude on salt intake and health. This may provide a crucial foundation in the development of cost-effective healthcare programs to widen knowledge, create awareness and promote a healthy lifestyle by reducing salt intake and further reduce the prevalence of non-communicable diseases.

    Background: Human brain endothelial cells (HBECs) are part of the blood-brain barrier (BBB). BBB acts as a barrier to control the passage of molecules or materials from the blood into the brain. Identification of specific proteins changes in their expressions that are related to disease state is important in order to understand the disease mechanism involving brain vasculature. To achieve that, the techniques involve in identifying the proteins of interest must be optimized prior to further investigation. Methodology: In this study, identification of Claudin-5 in HBEC lysates was tested using different sample preparation techniques such as; 1) reducing with Dithiothreitol (DTT) and non-reducing conditions; 2) denaturing by heating at 95°C for 5 minutes or 70°C for 20 minutes and 3) protein loading at 3 and 4 µg. The samples were then subjected to an automated capillary-based immunoassay, Jess. Results and Discussion: The results showed that HBEC samples loaded at 4 µg and heated for 5 minutes at 95°C with DTT produced clearer and intense bands for Claudin-5 identification compared to the other set ups. As reducing condition and denaturing by heated at 95°C for 5 minutes conditions demonstrated good results, the conditions were used to identify ICAM-1 expression at different protein loading (3 and 4 µg). The result demonstrated that HBEC samples heated for 5 minutes at 95°C with DTT and loaded at 4 µg produced a good detection for ICAM-1. Conclusion: These optimized conditions could be served as a standard procedure for further identification of Claudin-5 and ICAM-1 proteins in HBEC using a capillary immunoassay instrument.

    Background: The Malaysian Dietary Guidelines recommended that at least two servings of fruits and three servings of vegetables be consumed daily. However, is there a relationship between daily fruit and vegetable intake and body mass index (BMI)? The aim of this study was to identify the relationship between fruit and vegetable intake and BMI among postgraduate students in the health sciences. Methodogy: A cross-sectional study was conducted at the Faculty of Health Sciences, Universiti Kebangsaan Malaysia. 44 postgraduate students from the 2019/2020 batch of health sciences took partn in this study. Respondents were asked to complete three parts of the questionnaire: socio-demographic data, anthropometric measurements, and self-administered questions. Results: The majority of respondents are female (n=44, 77.3%), and they are mainly Malay (n=22, 50.0%). The average BMI of all respondents is 23.76±4.83. This study found that majority of respondents did not meet the recommended daily fruit (n=31, 70.5%) and vegetable intake (n=23, 52.3%). Discussion: The study discovered a significant relationship (p0.05) between gender, age, BMI, waist circumference, and daily fruit intake. Moreover, neither daily fruit nor vegetable intake predicted changes in BMI. Conclusion: This study found that the consumption of fruits and vegetables among postgraduate students was unsatisfactory and lower than recommended guidelines.

    BACKGROUND: Vaccination is an effective way to curtail the burden of COVID-19 in which success depends on a high acceptance of the vaccine. However, addressing concerns among vaccine-hesitant individuals is essential to avoid failure of the immunisation programme. This study sought to assess the concerns and acceptance rates regarding the COVID-19 vaccine among Malaysians.

    METHODS: An online questionnaire was distributed to 1411 respondents via a snowball sampling method among Malaysians aged 18 years and above.

    RESULTS: The majority of the respondents were young adults (40.7%), female (62.8%), Malay (63.8%), Muslim (72.3%), married (52.9%), with tertiary education (86.8%) and without medical illness (85%). Social media (97.4%) was the primary source of information regarding COVID-19. The overall acceptance rate was high (83.3%), with the lowest rates among the elderly aged 60 years and above (63.4%) and pensioners (64.6%). Hesitance was caused by concerns regarding side effects (95.8%), safety (84.7%), lack of information (80.9%), effectiveness (63.6%) and religious (20.8%) and cultural factors related to the COVID-19 vaccine (6.8%). Respondents with diabetes mellitus (24.7%) and hypercholesterolemia (23%) were more hesitant to accept the COVID-19 vaccine, at 16.1 and 15.8%, respectively. Predictors of COVID-19 vaccine hesitance were age, religion, and current residence.

    CONCLUSIONS: The results indicate a high rate of acceptance of the COVID-19 vaccine among Malaysians. Thus, the Malaysian government and other related agencies should increase their campaign and prepare to implement the COVID-19 mass immunisation programme among Malaysians. However, despite the high acceptance rate, it remains important to address concerns among hesitant individuals by building trust in vaccine safety and effectiveness through adequate information regarding the vaccine.

    BACKGROUND: International labour migration has become a crucial livelihood strategy, especially in countries where decently paid employment opportunities are limited. Such opportunities come with many potential benefits but also many stressors that challenge migrants' coping skills, especially when they are in a foreign environment away from their normal support network. This paper explores how labour migrants coped with migration-related stressors using a sample of male Nepali migrants.

    METHODS: Qualitative life histories were conducted in Kathmandu among returnee male migrants. Coping responses were categorised based Skinner and Zimmer-Gembeck's coping typologies. The interview scripts were transcribed in Nepali and translated into English for analysis. Each interview script was open coded and then categorised according to the 12 core coping families. Data were analysed thematically to explore relationships across and within coping and stressors.

    RESULTS: Forty-two men were interviewed who mainly worked in low- and semi-skilled jobs in Malaysia, and the Gulf States. The coping strategies most commonly used belonged to the families of problem-solving, support-seeking, negotiation and helplessness. Men used these either individually or collectively with other migrants. Those who sought assistance from authorities or civil society organisations did not always receive the help needed and there were mixed messages as to when and what types of assistance were available. Some stressors involved multiple coping strategies simultaneously, others described changing strategies following unsuccessful earlier attempts. The coping families of helplessness and social isolation reflected migrants' limited power in challenging certain stressors. The choice of coping strategies was also moderated by factors such as outstanding loans, language difficulties, or not wanting to cause their family distress. Some coping strategies used led to  new stressors.

    CONCLUSIONS: Migrants need greater clarifications on their rights with respect to contract discrepancies, the types of support available, how and from whom to access them once in destination. Improvements to the support mechanisms migrants can access as well as strengthening migrant-led initiatives in destination countries to support labour migrants' in managing stressors are needed. These may contribute to reducing the experiences and impact of such stressors, which may ultimately lead to more successful migration outcomes. As labour migration from Nepal is likely to continue, government and CSOs need to ensure migrants have the support they need to cope with the challenges they may encountered along the way.

    Cellulose and its forms are widely used in biomedical applications due to their biocompatibility, biodegradability and lack of cytotoxicity. It provides ample opportunities for the functionalization of supported magnetic nanohybrids (CSMNs). Because of the abundance of surface hydroxyl groups, they are surface tunable in either homogeneous or heterogeneous solvents and thus act as a substrate or template for the CSMNs' development. The present review emphasizes on the synthesis of various CSMNs, their physicomagnetic properties, and potential applications such as stimuli-responsive drug delivery systems, MRI, enzyme encapsulation, nucleic acid extraction, wound healing and tissue engineering. The impact of CSMNs on cytotoxicity, magnetic hyperthermia, and folate-conjugates is highlighted in particular, based on their structures, cell viability, and stability. Finally, the review also discussed the challenges and prospects of CSMNs' development. This review is expected to provide CSMNs' development roadmap in the context of 21st-century demands for biomedical therapeutics.
