Introduction: Broken glass exhibits unique fracture patterns depend upon the nature of the impact. The fracture patterns provide information like point and angle of impact, direction of force and sequence of firing. Recent studies have shown that the use of shotgun in Malaysia is increasing, yet, the relationship existing among the fracture pattern and the projectile impact factors are not well documented. The objective was to analyse the fracture characteristics on different glass types of variable thickness and distance made by shotgun ammunition. Methods: Soda lime and tempered glass panel with dimension of 12’x 12’ with 3 or 4 mm thickness were shot from various distances of 4, 6 and 8 m from the muzzle end of the shotgun. Samples were analysed under fixed parameters and observations were recorded. Results: It is found that the bullet hole diameter of 4 mm tempered glass were larger compared to 4 mm soda lime glass ranged from 14.33 to 24.17 cm as distance increased. Tempered glass surface also exhibited dicing fragments unlike soda lime glass where only radial fracture patterns are evident. This can be attributed to high inherent strength and ductility that makes the tempered glass remarkably resistant to external force. Conclusion: The findings from this study can lead to distinguish the type of glass through examination of fracture patterns, whether it is soda lime silica or tempered glass. The type of glass and the source of impact can be determined using the fragments, no reconstruction necessary.
This study presents a list of land snails and slugs found on limestone hills in the District of Bau, the state of Sarawak in Malaysian Borneo. Systematic and random sampling for land snails was conducted at eight limestone outcrops, namely, Gunung Stulang, Padang Pan, Gunung Kapor, Gunung Lobang Angin, Gunung Doya, Gunung Batu, Bukit Sekunyit and Gunung Sebayat. A total of 122 land snail species was documented with photographs of each species. Of the 122 species collected, 13 are new to science, namely, Acmella bauensissp. nov., Japonia bauensissp. nov., Plectostoma margaretchanaesp. nov., Microcystina arabiisp. nov., Microcystina atonisp. nov., Microcystina pariparisp. nov., Microcystina liratasp. nov., Microcystina oswaldbrakenisp. nov., Microcystina kilatsp. nov., Philalanka jambusanensissp. nov., Everettia microrhytidasp. nov., Everettia minutasp. nov., and Paralaoma sarawakensissp. nov.
Proper understanding the 'Instructions to authors' for a particular journal is the key towards successful submission of a manuscript which will lead to it being published. Common errors that are frequently made by authors in their submission to the Malaysia Journal of Malaysia (MJM) that lead to rejection of their submission or requiring major revisions or minor revisions are listed and discussed in this article. Outright rejection prior to even a peer review process may be made for an article due to: it is poorly written or when there is suspicion on the authenticity of the submission, which contains elements that are suspected to be plagiarised, it is a duplicate submission or not in the format required by the MJM. The editor in charge of the issue makes a recommendation to the Editor in Chief for the final decision.
Life table is a table that shows mortality experience of a nation. However, in Malaysia, the information in this table is provided in the five-years age groups (abridged) instead of every one-year age. Hence, this study aims to estimate the one-year age mor- tality rates from the abridged mortality rates using several interpolation methods. We applied Kostaki method and the Akima spline method to five sets of Malaysian group mortality rates ranging from period of 2012 to 2016. The result were then compared with the one-year mortality rates. We found that the method by Akima is the best method for Malaysian mortality experience as it gives the least minimum of sum of square errors. The method does not only provide a good fit but also, shows a smooth mortality curve.
Critical aortic stenosis (AS) is very severe narrowing at aortic valve in newborns, causing left ventricular outflow tract obstruction (LVOTO). It is lethal if not treated soon after birth.
Oil palm is one of the key industries highly observed in Malaysia, due to its high demand both whether locally or internationally. The oil extraction rate (OER) in palm oil production is used as an element to identify the performance of the mills, estates and producers. In view of this, there are specific instrument or sensor needs to be implemented at the mills especially during the reception of fresh fruit bunches (FFB) transported from the field for oil content processing. This paper aims to study and propose the use of a fruit battery-based oil palm maturity sensor to analyse the effect of the sensor to various parameters. The study utilizes a charging method with different parameters, including a moisture content test on the palm oil samples. Three types of parameters are tested along with the different grades of oil palm fruit from different bunches, such as the load resistance, charging voltage and charging time. The repeatability data of the samples are obtained with the used list of values in each parameter. The results show that the parameters tested for the unripe, under ripe and ripe samples can affect the sensor sensitivity.
Over the last few years, Universiti Malaysia Sabah (UMS) as part of its global marketing initiative opened its doors to international students to take up elective as well full time programmes. In September 2017, 36 nursing students from a university in China completed a 12-week elective /mobility programme in UMS.
Globally, 998 million tonnes of agricultural waste is produced per year and in Malaysia, 1.2 million tonnes of agricultural waste is disposed of into landfills annually. Concurrently, increasing demands of concrete leads to vary of research conducted on improving cement production methods and formulating reduction or eliminate CO2 emissions.
Kajian ini bertujuan untuk menentukan kekuatan pengaruh kepimpinan pengajaran guru besar, kompetensi profesionalisme guru dan kompetensi peribadi guru terhadap efikasi pengajaran guru bagi guru-guru sekolah rendah di zon Pedalaman, Sabah. Kajian ini melibatkan 361 responden yang terdiri daripada guru-guru sekolah rendah di zon Pedalaman, Sabah. Pemboleh ubah kajian telah diuji dengan menggunakan statistik deskriptif dan inferensi yang melibatkan skor min, sisihan piawai dan regresi berganda. Instrumen yang digunakan dalam kajian adalah soal selidik yang diadaptasi daripada Principal Instructional Management Rating Scale (PIMRS), Standard Guru Malaysia (SGM) dan Teacher Efficacy Scale (TES) bagi mengumpul data daripada 361 responden yang telah melengkapkan borang soal selidik, daripada 54 buah sekolah rendah yang melibatkan tujuh daerah di zon Pedalaman, Sabah. Persampelan secara rawak digunakan dalam pemilihan responden dalam kalangan guru manakala persampelan bertujuan digunakan bagi menentukan bilangan sekolah yang mewakili setiap daerah seperti yang telah ditetapkan. Statistik deskriptif dan inferensi telah digunakan bagi menghuraikan dapatan kajian. Dapatan kajian menunjukkan bahawa tahap kepimpinan pengajaran guru besar (Min = 4.52; SP = 0.313) pada tahap sangat tinggi, kompetensi profesionalisme guru (Min = 4.41; SP = 0.295) juga pada tahap sangat tinggi dan kompetensi peribadi guru (Min = 4.47; SP = 0.366) juga berada pada tahap sangat tinggi manakala efikasi pengajaran guru (Min = 3.96; SP = 0.358) berada pada tahap tinggi. Data inferensi dianalisis menggunakan regresi berganda. Analisis regrasi menunjukkan pengaruh kepimpinan pengajaran guru besar menyumbang 65 peratus, kompetensi profesionalisme guru menyumbang 65.9 peratus dan kompetensi peribadi guru menyumbang 66.5 peratus terhadap efikasi pengajaran guru dan merupakan peramal yang signifikan kepada tahap efikasi pengajaran guru.
