Deworming the grinder for successful extrication of a mangled hand: a case report

Grinding machine injuries are known to cause severe mutilating injuries of the upper limb. In some cases, the machinery equipment may still be attached to the limb when the patient reaches the hospital. In treating these injuries, the patient’s hemodynamic status should be the first priority of resuscitation. Following this and whenever possible, a reversal of the grinding mechanism should be done to free the limb. This would allow assessment of the extent of zone-of-injury prior to starting the surgical procedure. We report a case of a 28-year-old male who sustained a mangled hand injury that was successfully extricated from an industrial grinding machine, thereby allowing preservation of precious length of the limb during surgery. This case highlights the importance of adhering to safety precautions at the workplace to reduce the risk of potential occupational hazards when dealing with machinery equipment

Development of auditing in Malaysia: Legal, political and historical influences

This work investigates the role and contribution of external auditing as practised in the Malaysian society during the forty year period from independence in 1957 to just before the onset of the Asian Financial Crisis in 1997.It applies the political economic theory introduced by Tinker (1980) and refined by Cooper & Sherer (1984), which focuses on the social relations aspects of professional activity rather than economic forces alone.In a case study format where qualitative data was gathered mainly from primary and secondary source materials, the study found that the function of auditing in the Malaysian society in most cases is devoid of any essence of mission; instead it is created, shaped and transformed by the pressures which give rise to its development over time.The largely insignificant role that it serves is intertwined within the contexts in which it operates

Experimental investigation on enhanced microscale heat transfer - inverted fish scale channel

The introduction of micro-channel heat sink significantly increases the efficiency and effectiveness of heat dissipation due to its high heat transfer effect. However this technology is not widely utilized due to its high cost in fabrication. This research presents the enhanced microscale heat transfer effect by combining two macro geometries, which may be fabricated with less complexity and at lower cost. An annular micro-channel of 300 micrometer gap is formed by insertion of a cylindrical stainless steel insert with 19.4mm outer diameter into a copper pipe with inner diameter of 20.0mm. Effects of Inverted Fish Scale (IFS) insert on heat transfer coefficient and pressure drop were examined based on the ratio of insert profile height (e) to channel height (H), and ratio of insert pitch length (P) to insert profile height (e) at heat flux of 1000W ranging from 2.0 L/min to 8.0 L/min. For IFS insert with different e/H ratio, the results show that the average heat transfer effect is higher at higher e/H ratio. The highest heat transfer coefficient was achieved by e/H=0.7, which recorded the absolute value of 35.4 kW/m²•K at 5.5 L/min, corresponding to pressure drop of 1.887 bar. For e/H=0.7, the enhancement of heat transfer coefficient is roughly doubled when compared to Plain insert at each Reynolds number. In the study of P/e ratio, the highest average heat transfer coefficient was achieved by P/e=5 at 5.5 L/min, which was 36.01 kW/m²•K, with the pressure drop of 2.918 bar. Similarly, e/H=0.7 offers double heat transfer enhancement when compared to Plain insert at each Reynolds number. Future research should focus on finding the optimal relative enhancement of heat transfer effect to pressure drop increment for IFS insert by altering insert profile parameters based on this research finding. New nature-inspired insert profiles which can be manufactured at low costs and achieve better heat transfer and hydrodynamic performance compared to IFS insert design are encouraged.Bachelor of Engineering (Mechanical Engineering

Threshold.

In a dingy motel room that is as hot and clammy as the jungle painted on its walls, a sexual threesome has been arranged to take place. Except that the two men lying in wait are officers from the Central Narcotics Bureau, ready to apprehend their suspect, who is going to show up with Crystal Meth at any moment. Staff Sergeant Boon is garrulous and relaxed; for him, this is a job just like any other. Inspector Anton, on the other hand, is preoccupied and tense, and is increasingly restless. As the wait for the suspect lengthens, it is apparent Anton has something infinitely more personal at stake. In what appears to be a routine crackdown operation, which walls will come tumbling down, and what thresholds will be crossed? In the filmʼs tropical swelter, how does one ascertain that everything one sees is not a mirage from a fragmenting mind?Bachelor of Fine Art

Discal cyst, a physical risk: a case report on endoscopic resection

Discal cysts are a rare diagnosis involving the formation of an intraspinal extradural cyst. They are a diagnostic challenge as it is difficult to differentiate discal cysts from other causes of back pain, neurological deficit, and radiculopathy. Due to its rarity, there is a lack of research-based evidence on the optimal management of the discal cyst. This case report aims to increase awareness of this diagnosis and to highlight a possible treatment option for this condition

Application of a deep learning algorithm in the detection of hip fractures

Summary: This paper describes the development of a deep learning model for prediction of hip fractures on pelvic radiographs (X-rays). Developed using over 40,000 pelvic radiographs from a single institution, the model demonstrated high sensitivity and specificity when applied to a test set of emergency department radiographs. This study approximates the real-world application of a deep learning fracture detection model by including radiographs with sub-optimal image quality, other non-hip fractures, and metallic implants, which were excluded from prior published work. The study also explores the effect of ethnicity on model performance, as well as the accuracy of visualization algorithm for fracture localization
