    Swiftlet
    s
    are small insectivorous birds which breed throughout Southeast Asia and
    the South Pacific.
    Among many swiftle
    t species, only a few are notable to produce edible bird’s
    nest
    s
    (EBN) from the secreted saliva during breeding seasons.
    The taxonomy of swiftlet
    s
    remains one of the most controversial in the avian species due to the high similarity in
    morphological charac
    teristics among the species. Over the last few decades, researchers have
    studied the taxonomy of swiftlet
    s
    based on the morphological
    trade
    , behavior, and genetic
    traits
    .
    However, despite all the efforts,
    the
    swiftlet taxonomy remains unsolved.
    The
    EBN is one of
    the
    most expensive animal products
    and frequently being referred
    to
    as the “
    Caviar of the East
    ”.
    The
    EBN market value varies from
    US
    $1000.00 to
    US
    $10,000.00 per kilogram depend
    ing
    on
    its grade, shape, type and origin.
    Hence, bird’s nest harve
    sting is considered a lucrative industry
    in many countries in Southeast Asia.
    However,
    the
    industry faced several challenges over the
    decades such as the authenticity of the EBN, the quality assurance and the depletion of swiftlet
    population. Furthermore,
    there is limited scientific evidence regarding EBN’s medical benefits
    as
    claimed by manufacturers. This paper reviews the taxonomy of swiftlet
    s
    , its morphological
    characteristics, the challenges currently encountered by the industry, and finally the
    compos
    ition and medical benefits of EBN.

  2. Status Kegiatan Pembangunan Perisian di Malaysia (Status of Software Development in Malaysia)
    Aziz Bin Deraman, Ahmad Shukri Bin Yahaya
    Sains Malaysiana, 1997;26.
    A study was conducted to examine the usage of application software and its development practices in Malaysia. The study has shown that the use of application software is greatly emphasized by organizations in their respective businesses. And for most organizations, the application software is supplied by a vendor or through in house development. For the software development practices, the deployment of a current technique and technology is still inadequate. Therefore, most of the existing information technology practitioners should be given additional training on the latest techniques of software development. Other aspect of improvement on software development practices is also discussed.
    Satu kajian terhadap status pemakaian dan kegiatan pembangunan perisian gunaan di Malaysia telah dijalankan. Kajian ini menunjukkan yang aspek pemakaian sangat diberi penekanan oleh organisasi. Manakala proses perolehan perisian gunaan pula terbahagi secara setara di antara buat sendiri dengan menggunakan pihak ketiga. Namun begitu yang ketara ialah kadar penggunaan teknologi dan teknik terkini dalam kegiatan pembangunan perisian masih berkurangan. Oleh itu disarankan supaya aspek latihan teknik kakitangan teknologi maklumat organisasi perlu dipertingkatkan secara berterusan. Di samping itu kajian ini memaparkan beberapa aspek amalan pembangunan perisian yang boleh diperbaiki lagi.

    Shahrudin S, Jaafar IH, Rahim ND, Akil MA
    Trop Life Sci Res, 2011 May;22(1):13-24.
    PMID: 24575206
    The herpetofauna of Beris Valley, Kedah, Malaysia, was studied using a rapid assessment survey during a scientific expedition organised by the School of Biological Sciences at the Universiti Sains Malaysia, from 14-17 August 2009. All amphibians and reptiles were observed and captured during the four-day survey along the ditches, roads, dam areas, swamps, forest trails and streams. The results showed that 14 species of amphibians from 9 genera and 5 families inhabit the area, and 7 species of lizards, 5 species of snakes and 2 species of freshwater turtles were also present in the area. Fejervarya limnocharis and Microhyla butleri seemed to be the most common amphibians, while Hemidactylus frenatus and Varanus salvator were the most common reptiles in the area. This report constitutes a preliminary checklist and first record of amphibians and reptiles in Beris Valley, Kedah. The number of specimens was less than expected because of the very short survey period, but we hope to record more species in future studies.

    Tao H, Rahman MA, Al-Saffar A, Zhang R, Salih SQ, Zain JM, et al.
    Work, 2021;68(3):853-861.
    PMID: 33612528 DOI: 10.3233/WOR-203419
    BACKGROUND: Nowadays, workplace violence is found to be a mental health hazard and considered a crucial topic. The collaboration between robots and humans is increasing with the growth of Industry 4.0. Therefore, the first problem that must be solved is human-machine security. Ensuring the safety of human beings is one of the main aspects of human-robotic interaction. This is not just about preventing collisions within a shared space among human beings and robots; it includes all possible means of harm for an individual, from physical contact to unpleasant or dangerous psychological effects.

    OBJECTIVE: In this paper, Non-linear Adaptive Heuristic Mathematical Model (NAHMM) has been proposed for the prevention of workplace violence using security Human-Robot Collaboration (HRC). Human-Robot Collaboration (HRC) is an area of research with a wide range of up-demands, future scenarios, and potential economic influence. HRC is an interdisciplinary field of research that encompasses cognitive sciences, classical robotics, and psychology.

    RESULTS: The robot can thus make the optimal decision between actions that expose its capabilities to the human being and take the best steps given the knowledge that is currently available to the human being. Further, the ideal policy can be measured carefully under certain observability assumptions.

    CONCLUSION: The system is shown on a collaborative robot and is compared to a state of the art security system. The device is experimentally demonstrated. The new system is being evaluated qualitatively and quantitatively.

  6. Dissolving the engineering moral dilemmas within the Islamic ethico-legal praxes
    Solihu AK, Ambali AR
    Sci Eng Ethics, 2011 Mar;17(1):133-47.
    PMID: 19937149 DOI: 10.1007/s11948-009-9185-7
    The goal of responsible engineers is the creation of useful and safe technological products and commitment to public health, while respecting the autonomy of the clients and the public. Because engineers often face moral dilemma to resolve such issues, different engineers have chosen different course of actions depending on their respective moral value orientations. Islam provides a value-based mechanism rooted in the Maqasid al-Shari'ah (the objectives of Islamic law). This mechanism prioritizes some values over others and could help resolve the moral dilemmas faced in engineering. This paper introduces the Islamic interpretive-evaluative maxims to two core issues in engineering ethics: genetically modified foods and whistleblowing. The study aims primarily to provide problem-solving maxims within the Maqasid al-Shari'ah matrix through which such moral dilemmas in science and engineering could be studied and resolved.

    Phorid flies play an important role in forensic cases and can cause myiasis in humans. Studies on phorid flies species diversity are still limited in Malaysia. This research was carried out to collect information about species and frequency distribution of phorid flies as to provide more information on their roles in forensic and medical entomology. Bait trap was used with 100 g beef liver as baits. The species of the flies were identified using identification keys from Disney as well as Brown and Oliver. There were 449 phorid flies found in Kepong, Kuala Lumpur including Megaselia scalaris, Megaselia spiracularis, Megaselia sp. and phorid flies of genus X. Female phorid flies (98.89%) were found more prone to be trapped compared to male phorid flies (1.11%). Most phorid flies trapped in Kepong, Kuala Lumpur were from genus Megaselia and consisted of female flies. A total of five species of phorid flies probably new to science were also discovered. This study showed that Megaselia flies were found indoors rather than in open spaces. This was corresponding to their discoveries among the decomposing corpse found inside premises.

  8. Fulltext The pH of very dilute solutions of strong acids – a calculation for a medical or biomedical class involving the application of simple numerical skills
    Barling, Peter Michael
    International e-Journal of Science, Medicine & Education, 2012;6(2):32-38.
    MyJurnal
    This paper presents the solution to a calculation of the pH of a very dilute solution of a strong acid or base, taking into account the effect of the hydronium or hydroxyl ions generated from the ionisation of the strong acid or base on the ionisation of water, as a second very weak acid. To be solved successfully, this calculation involves the concepts of conservation of charge, pH and the application of the general solution to a quadratic equation. Such an exercise involves the application of skills in basic numeracy, and can provide a core of understanding that can prepare students for
    many different sorts of calculations that represent reallife problems in the medical and biological sciences.A programme is presented in C++ which enables the work of students to be individualised so that each student in a class can work through a slightly different pH calculation, in such a way that a class supervisor can quickly check each student’s result for accuracy. This exercise is presented as a potential means of enabling students to undertake and master similar types of calculations involving simple or more complex equilibria.

    MyJurnal
    Introduction: The Infant and Early Childhood Nutrition Task Force, International Life Sciences Institute Southeast Asia (ILSI SEA) Region, organised the 1st and 2nd Expert Consultation and Planning Meeting on Infant and Early Childhood Nutrition in 2009 and 2011, respectively. The goal of the consultations was “to generate and promote relevant science-based information that will help improve nutritional status, growth and development of infants and young children in Southeast Asia.” Methods: An Expert Panel Core Group was created whose role is to provide advice and recommendations through a review of current scientific knowledge regarding issues related to early childhood growth and nutrition. The Panel is composed of experts representing 7 countries (China, Indonesia, Malaysia, Philippines, Singapore, Thailand, and Vietnam). In July 2012, the Panel convened the 3rd Expert Consultation and Planning Meeting on Infant and Young Child Nutrition in Singapore. This report presents the highlights of the meeting and recommendations made by the Panel on ways to improve infant and young child nutrition in Southeast Asia. Results and Conclusion: The effective use of WHO indicators for assessing infant and young child feeding practices, mitigating the effects of maternal employment on breastfeeding, using behaviour change communication, updating the education of health personnel, and improving maternal health were considered important actions to be taken. Since current feeding practices in Southeast Asia fall short of WHO recommendations, studies are needed to develop strategies which take into consideration the diverse cultural settings that characterise the region.

    MyJurnal
    Cancer research is an extremely broad topic covering many scientific disciplines including biology (e.g. biochemistry and signal transduction), chemistry (e.g. drug discover and development), physics (e.g. diagnostic devices) and even computer science (e.g. bioinformatics). Some would argue that
    cancer research will continue in much the same way as it is by adding further layers of complexity to the scientific knowledge that is already complex and almost beyond measure. But we anticipate that cancer research will undergo a dramatic paradigm shift due to the recent explosion of new discoveries in cancer biology. This review article focuses on the latest horizons in cancer research concerning cancer epigenetics, cancer stem cells, cancer immunology and cancer metabolism.

  12. Tailoring teaching instructions according to student’s different learning styles: are we hitting the right button?
    Chew, Keng-Sheng
    Education in Medicine Journal, 2016;8(3):0-0.
    MyJurnal
    To address the diverse preferred learning styles, one of the oft-cited recommendations for educatorsis to tailor teaching instructions accordingly. This pedagogy however, lacks scientific evidences.Furthermore, in medical curriculum, tailoring instructions according to preferred learning styles isnot pragmatic. This is because different subjects and in different settings matter may be best deliveredin specific delivery mode. Furthermore, patients’ presentations are often multi-sensorial. As such, theonus is on the students themselves to adjust the amount of learning efforts they put in according totheir preferred or not preferred learning styles.

    Recently, the zebrafish has gained in popularity as a vertebrate animal model for biomedical research. Commercial zebrafish housing systems are available and are designed to maximize stocking density of fish for a given space, but these systems are expensive and purchasing them may not be feasible for emerging laboratories with limited funding. In this article, we describe the construction of a simple and affordable recirculating zebrafish housing system. This system can be constructed in 3 working days, with materials readily available in hardware stores. The cost for construction of the system was only 3,000 MYR (750 USD). The system consists of a water reservoir, a supply line that delivers water to the shelves holding the zebrafish tanks, and a drainage line that receives water from both the supply line and the shelves containing the fish tanks and returns this water to the reservoir. This system also has a 3-stage filtration process to ensure that clean water is delivered to the zebrafish tank. The system can house up to 360 zebrafish. This low-cost housing system may make research using zebrafish feasible some laboratories.

    PMID: 28929028 DOI: 10.7717/peerj.3811
    Life science ontologies play an important role in Semantic Web. Given the diversity in fish species and the associated wealth of information, it is imperative to develop an ontology capable of linking and integrating this information in an automated fashion. As such, we introduce the Fish Ontology (FO), an automated classification architecture of existing fish taxa which provides taxonomic information on unknown fish based on metadata restrictions. It is designed to support knowledge discovery, provide semantic annotation of fish and fisheries resources, data integration, and information retrieval. Automated classification for unknown specimens is a unique feature that currently does not appear to exist in other known ontologies. Examples of automated classification for major groups of fish are demonstrated, showing the inferred information by introducing several restrictions at the species or specimen level. The current version of FO has 1,830 classes, includes widely used fisheries terminology, and models major aspects of fish taxonomy, grouping, and character. With more than 30,000 known fish species globally, the FO will be an indispensable tool for fish scientists and other interested users.

  16. Fulltext Investigation of the dynamical structures of double-chain deoxyribonucleic acid model in biological sciences
    Yousaf MZ, Abbas M, Nazir T, Abdullah FA, Birhanu A, Emadifar H
    Sci Rep, 2024 Mar 17;14(1):6410.
    PMID: 38494490 DOI: 10.1038/s41598-024-55786-z
    The present research investigates the double-chain deoxyribonucleic acid model, which is important for the transfer and retention of genetic material in biological domains. This model is composed of two lengthy uniformly elastic filaments, that stand in for a pair of polynucleotide chains of the deoxyribonucleic acid molecule joined by hydrogen bonds among the bottom combination, demonstrating the hydrogen bonds formed within the chain's base pairs. The modified extended Fan sub equation method effectively used to explain the exact travelling wave solutions for the double-chain deoxyribonucleic acid model. Compared to the earlier, now in use methods, the previously described modified extended Fan sub equation method provide more innovative, comprehensive solutions and are relatively straightforward to implement. This method transforms a non-linear partial differential equation into an ODE by using a travelling wave transformation. Additionally, the study yields both single and mixed non-degenerate Jacobi elliptic function type solutions. The complexiton, kink wave, dark or anti-bell, V, anti-Z and singular wave shapes soliton solutions are a few of the creative solutions that have been constructed utilizing modified extended Fan sub equation method that can offer details on the transversal and longitudinal moves inside the DNA helix by freely chosen parameters. Solitons propagate at a consistent rate and retain their original shape. They are widely used in nonlinear models and can be found everywhere in nature. To help in understanding the physical significance of the double-chain deoxyribonucleic acid model, several solutions are shown with graphics in the form of contour, 2D and 3D graphs using computer software Mathematica 13.2. All of the requisite constraint factors that are required for the completed solutions to exist appear to be met. Therefore, our method of strengthening symbolic computations offers a powerful and effective mathematical tool for resolving various moderate nonlinear wave problems. The findings demonstrate the system's potentially very rich precise wave forms with biological significance. The fundamentals of double-chain deoxyribonucleic acid model diffusion and processing are demonstrated by this work, which marks a substantial development in our knowledge of double-chain deoxyribonucleic acid model movements.

    Detection and quantification of DNA is critical to many areas of life sciences and health care, from
    disease diagnosis to drug screening. The transduction of DNA through electrochemical methods have a fast response rate and with a conductometric device like the silicon nanowire which can be fabricated to have a similar diameter of the DNA molecule being targeted, detection is real-time. Critical to this is the interfacing of a current-source and an amplifier capable of achieving a maximum of 10 pico ampere input bias. In this project, we fabricated a silicon nanowire using the top down approach and built a circuit that can mimic the output signal as low as 12 nA and achieved a gain of 1 million to be interfaced with the nanowire for real-time DNA detection.
