Copper Brace Method: A New Technique for Reconstructing Broken Bone Fragments
Human skulls and other bones recovered in forensic
anthropological contexts may be found broken into multiple pieces,
requiring reconstruction. This article prescribes a new method,
termed copper-brace met hod, that simultaneously enables retaining
the matching pieces of bones and readjusting them during the process
of reconstruct ion, ensuring an acceptable likeness in the spatial and
contour configuration of the final reconstruction
Nocturnal Ovipositioning of Flies
Post-mortem interval (PMI) is calculated by ascertaining the age of the immature
stages of blow flies demonstrating the longest period of association with decomposed
human remains. The time at which the flies oviposit is generally assumed to be during the
day time in which the flies are known to be active. A few researchers have indicated that
limited number of flies do oviposit during night hours and under artificial lighting
although studies on twilight ovipositioning have not been carried out so far. Moreover,
previous researchers have indicated the use of mutton purchased from the market which
does not preclude the possibility of flies depositing the eggs in the market place. This
thesis is the compendium of findings of a research that addressed, for the first time, the
possibility of ovipositioning during twilight as well as using beef purchased directly from
the slaughter house in Kota Bharu, Kelantan. The control and night experiments were
carried out inside the campus of Universiti Sains Malaysia, Kelantan. The results indicate
the possibility of limited ovipositioning during the twilight period which further declines
during the night period although ovipositioning is found significantly delayed by 4 to 5
days after continuous exposure of the animal model during the twilight and night time
while diurnal oviposition in the control animal model does not indicate such delay. It is
argued here that the delayed appearance of limited maggots attributable to nocturnal
ovipositioning need not be construed as a factor attributing to estimating longer PMI since
the maggots on account of immediate diurnal ovipositioning are the ones that are longer
and considered for estimating PMI. It is suggested that PMI has to be estimated only by
considering diurnal ovipositioning and the possibility of disposal during night has to be
left for the investigating agency to establish through evidence other than entomological
Verification and explanation of the prophetic traditions (Hadiths) of kindness to animals
This research includes a collection of Hadiths (prophetic traditions) mentioned by Prophet Mohammad (Peace and blessings of Allah be upon him), in which he urged Muslims to deal kindly with the animals when Muslims use these animals for all purposes like riding, loading milking and even slaughtering them.
The researcher has also verified the authenticity, judged and explained all of these respective Hadiths in a wise way to show the greatness of Islam in dealing with animals; he was neither lengthy nor short. In fact, the greatness of Islam is clearly shown in dignifying these animals which, in turn, entails how Islam honors the humans and prioritize them in treatment and dignity

Blood glucose test results showed ginger extract combination dose of 1.5 mg/20g mice and zinc doses 0.4 mg/20g mice were able to lower blood glucose levels comparable to metformin dose of 1.3 mg/20 g mice
Erosion-Corrosion Simulation of Thermally Sprayed WC-Based Cermet in Artificial Seawater and Dam Water Environments
Mechanical equipment operated in a water dam environment is at risk of erosion-corrosion. To address this issue, thermally sprayed cermet coatings are an adequate solution for increasing resistance to corrosion and wear in hydro turbines, especially with high river sedimentation loads such as those in Cirata and Jatiluhur dams in Indonesia. In this study, WC-based cermet coatings with WC-10Co-4Cr and WC-12Co respectively were coated on AISI 1030 steel substrate and evaluated in media simulating the Cirata and Jatiluhur water dam environments, as well as in simulated seawater conditions. The morphology and structure of the sprayed coating were analyzed by SEM and XRD, and microhardness, porosity, and surface roughness were also studied. The corrosion resistance of the coating was evaluated using potentiodynamic polarization. More importantly, erosion-corrosion resistance in seawater simulations studied by Closed Flow Loop System (CFLS) equipment utilizing coupon tests was also explored. The results showed that the WC-10Co-4Cr coating has good electrochemical corrosion resistance with less erosion-corrosion compared to the WC-12Co coating, at 0.06-0.15 mm/year and 0.16-0.26 mm/year, respectively. Coatings with Cr content show a lower corrosion rate due to the formation of stable WCr2O6 and W18O49 oxides, making them a good choice for coating hydro turbine components
Factors affecting the eco-environment identification through change detection analysis by using remote sensing and GIS: a case study of Tikrit, Iraq
Changes in eco-environment that are caused by climate changes and human exploitation have been a significant problem around the whole world for a long time. The eco-environment of Iraq is exposed to degradation, particularly in the middle and southern parts. By using an approach that combines remote sensing and GIS, this study examines the changes that have occurred during various periods between 1972 and 2010 in the Tikrit district in Iraq and identifies the factors responsible for the degradation. A significant change was observed in the area covered by vegetation and water, especially between 1990 and 2010, which exacerbated desertification as the vegetation and water area decreased by 16 and 59.6%, respectively. Also, the urban area increased with varying paces of growth. In the period 1990–2000, the urban area increased by 8.8% only, which is not surprising considering the population increase. However, between 2000 and 2010, the urban area increased dramatically by 47.5%, due to the war which led to migration from Baghdad (Iraq Capital) to Tikrit. This study proves that climate change, desertification, and immigration due to wars were the major roles in changing the environment. Also, it reveals that geospatial techniques can be successfully used to monitor the effects on the land cover/ use changes and, hence, on the eco-environment
A PRELIMINARY STUDY OF SEXUAL DIMORPHISM OF SCAPULA BY COMPUTED TOMOGRAPHY IN THE MALAYSIAN POPULATION
Objective: Sex estimation is one of the crucial steps for human identification, which is evident in cases of commingled, eroded, and/or missing remains. When pelvis or skull are unavailable, scapula has been used as an alternative bone for determining sex. Besides, the scapula was shown to be population-specific in several studies. Limited dry bone collections in Malaysia have led to various recommendations of virtual anthropology studies of bone in human identification. The aims of this study were to investigate the sexual dimorphism of the scapula using three-dimensional (3D) computed tomography (CT) imaging and to generate population-specific equations for sex determination in the Malaysian population.Methods: A total of 66 CT thorax images of 33 males and 33 females were taken. Morphological breadth (MB) and morphological length (ML) on bilateral scapulae were measured on 3D CT reconstructed images. Independent t-test and discriminant function analysis (DFA) were performed for analysis.Results: Results revealed that both parameters showed sexual dimorphism of scapula but displayed no difference between the right and left scapulae. DFA showed that MB and ML had high accuracy for sex estimation. The equations were highly accurate when both parameters were used in combination, followed by MB only and ML only, in that sequence.Conclusion: In brief, scapula measurements may be useful for forensic assessment of sex in the Malaysian population
The post-mortem resilience of facial creases and the possibility for use in identification of the dead
The post-mortem resilience of facial creases was studied using donated bodies in order to establish the
efficacy of crease analysis for identification of the dead. Creases were studied on normal (pre-embalmed)
and bloated (embalmed) cadavers at the Centre for Anatomy and Human Identification (CAHID) to
establish whether facial bloating would affect facial crease visibility. Embalming was chosen to simulate
the effects produced by post-mortem bloating. The results suggested that creases are resilient and
changes were only detected for creases located on the periphery of the face, particularly at areas where
the skin is thick, such as at the cheeks. Two new creases not previously classified were identified; these
creases were called the vertical superciliary arch line and the lateral nose crease. This research suggests
that facial creases may be resilient enough after death to be utilised for human identification
Comparison of 3D reconstruction of mandible for preoperative planning using commercial and open-source software
3D printing of mandible is important for pre-operative planning, diagnostic purposes, as well as for education
and training. Currently, the processing of CT data is routinely performed with commercial software which increases the
cost of operation and patient management for a small clinical setting. Usage of open-source software as an alternative to
commercial software for 3D reconstruction of the mandible from CT data is scarce. The aim of this study is to compare
two methods of 3D reconstruction of the mandible using commercial Materialise Mimics software and open-source Medical
Imaging Interaction Toolkit (MITK) software. Head CT images with a slice thickness of 1 mm and a matrix of 512x512
pixels each were retrieved from the server located at the Radiology Department of Hospital Universiti Sains Malaysia. The
CT data were analysed and the 3D models of mandible were reconstructed using both commercial Materialise Mimics and
open-source MITK software. Both virtual 3D models were saved in STL format and exported to 3matic and MeshLab
software for morphometric and image analyses. Both models were compared using Wilcoxon Signed Rank Test and
Hausdorff Distance. No significant differences were obtained between the 3D models of the mandible produced using
Mimics and MITK software. The 3D model of the mandible produced using MITK open-source software is comparable to
the commercial MIMICS software. Therefore, open-source software could be used in clinical setting for pre-operative
planning to minimise the operational cost
