In the aeronautical field, sandwich structures are widely used for secondary structures like flaps or landing gear doors. The modeling of low velocity/low energy impact, which can lead to a decrease of the structure strength by 50%, remains a designer’s main problem. Since this type of impact has the same effect as quasi-static indentation, the s

Mathematics is a core subject for foundation students who will be taking up engineering, pharmacy, medicine and architecture. Therefore, it is crucial that a proper and effective method of teaching is adapted in order to build their understanding in mathematics. This paper discusses types of activities given based on problem based learning (PBL). 4

Previous work suggests a general reduction in complexity with aging, referred to as the aging-complexity theory. Fractal dimension (FD) of the vessels in the retina is a global measure of the complexity of the vasculature. However, earlier works did not find any correlation between aging and FD of the retinal vasculature, in contrast to the finding

To obtain precise calibre measurements, there are two general approaches: segment the vessels and measure the diameter, and to measure the diameter from the greyscale images. While there is a claim that vessel segmentation does not solve diameter measurement problems it has not been proven experimentally. The aim of this work is two-fold: first, to

OBJECTIVE To evaluate the clinical usefulness of CT Colonography after an incomplete or failed colonoscopy. MATERIALS AND METHODS After incomplete or failed colonoscopy, seventeen patients underwent CT Colonography before and after intravenous injection of iodinated contrast agent, in supine and prone positions. Two-dimensional multiplanar reformat

Video analysis of the dynamics of the tear meniscus height (TMH) have been used in the diagnosis of dry eye. However, the existing techniques require substantial manual intervention. This research work aims to automate the process of estimating the change in the inferior TMH without manual intervention.Automated Inferior Tear Meniscus Height Measur

Sepsis still remains one of the commonest cause of ntensive care admission here in Malaysia. In the last six years following the first edition, there has been burgeoning increase in knowledge and usage of antimicrobials. However the pressing issues of growing antimicrobial resistance, inappropriate therapy and escalating cost compel for a more resp

Achilles tendon injury is a common cause of disability in adult sportsmen. The majority of cases are due to overuse injury often exacerbated or precipitated by specific and recognizable factors. The main reason is probably the increased popularity of recreational sports among middle-aged people. The 2 most frequently discussed pathophysiological th

In this paper, we describe an innovative process involving iron reduction through chemical vapor deposition for applications in the ironmaking industry. In our experiment, we produced tar vapors from pyrolysis of various solid fuels, including high-grade bituminous coal (HGC), low-grade lignite coal (LGC), and biomass palm kernel shell (PKS), and d

Cultivable marine bacteria associated with the sponge Hyattella cribriformis (Hyatt, 1877) was studied through 16S rRNA gene sequencing. These marine bacterial colonies produced on Zobell Marine agar plates were distinguished based on phenotypic characters viz., colony morphology and pigmentations of the individual colonies. The extracted DNA from
