Publication The Effect of Cement and wrapping on the Decomposition rate of the Rabbit Carcasses(Heighten Science Publications Corporation, 2017) ;Lai Poh Soon ;Khoo Lay See ;Nazni Wasi Ahmad ;Azlina Zulkapli ;Nurul Kharmila Abdullah ;Mohd Shah MahmoodAhmad Hafizam HasmiTaphonomic study was fi rst time conducted in Kuala Lumpur, capital city of Malaysia. In this research model, male Oryctolagus cunicullus weighed 1.8-2.6 kg each were killed by Dolethal intravenously at the ear region. In Phase 1 study, eight subjects were wrapped in a sack and cemented within a container to be compared with the other four controls at each location labelled A (ground) and B (manmade freshwater pond). Phase 2 involved duplicating set of 15 cemented samples comparable to 1 control made up to total of 32 subjects which were all put into a compact polytank containing freshwater to simulate a case study. Taphonomic changes were observed and scored using TBS system incorporating of fresh stage, early decomposition stage, advanced decomposition stage and skeletonisation stage. The ambient temperature of surroundings with 28.81C�4.21�C and 29.21�C�4.57�C (mean�S.D.) while relative humidity of air with 74.49 %�14.61% and 79.15%�16.32% (mean�S.D.) were recorded for Phase 1 and Phase 2 study respectively. Time taken for ground control exposed and wrapped carcasses to reach fi rst sign of skeletonised stage were four days and fi ve days respectively. Whilst freshwater controls reached initial skeletonised stage within one week for exposed carcass and two weeks for wrapped carcass. Within the control and cemented sample carcasses, TBS scores increased from initial stages of decomposition and become plateau after advanced decomposition. The cementing factor have superseded the wrapping factor due to its stronger physical barrier effect to slow down the decomposition more than half compared to controls based on Multiple way ANOVA test. Phase 2 study has demonstrated more accurately on the decomposition rate of the cemented samples. It showed that wrapping and cementing factors have delayed the decomposition process of the rabbit carcasses about 4 times to reach the initial stage of skeletonisation compared to the control carcasses. There was absence of insect activity within the cemented samples, hence the microorganism activity would be the only contributor to the decaying process within the cemented samples at slower rate comparing to the exposed or wrapped controls. - Some of the metrics are blocked by yourconsent settings
Publication Fatal Injuries Among Motorcyclists In Klang Valley, Malaysia(Elsevier, 2014) ;Nurul Kharmila Abdullah ;Roszalina Ramli ;Jennifer Oxley ;Faridah Mohd Noor ;Mohd Shah Mahmood ;Abdul Karim TajuddinRoderick McClureBackground: Motorcycle fatalities constitute the majority of road traffic deaths in Malaysia. The aims of this study were to describe the pattern of fatal injuries among Klang Valley fatal motorcyclists and to describe the factors associated with fatal (vs non-fatal) injuries. Methods: A cross-sectional analysis was performed on data from a case series of injured (fatal and nonfatal) motorcyclists recruited from Klang Valley between 14th March 2010 and 13th March 2011. Fatal cases in the cases series were identified from the Police files. Non-fatal cases were recruited from five major hospitals in the study region. Information used in the analyses were obtained from Police crash reports, hospital medical records, and Coroner's records of the participant sample. Results: Of the 177 fatal cases, 142 (80.2%) were categorised as instantaneous death while 35 (19.8%) cases were categorised as experiencing delayed death. Thirty two percent of the cases had a Maximum Abbreviated Injury Score (MAIS) of 5 with head injury being the most common cause of death. Significant predictors of fatal (vs non-fatal) injury included ethnic groups, monthly income, alcohol and drug use and road type. Alcohol and drug use was shown to be the strongest predictor with adjusted odds ratio (AOR) of 14.77 (95% CI 3.32e65.65). Conclusion: Factors related to the motorcyclists, road user behaviour and the road environment as well as pre-hospitalisation emergency care must be addressed efficiently in low and middle income countries to reduce the number and severity of motorcycle-related injuries.
