By fine-tuning printer components and analyzing noise levels, the primary goal is to minimize the noise produced by a 3D laser printer. The study involves modifying various printer parts and using a R...

Chemical composition, detoxification and modification of cassava and properties of their composites

Kenaf is one type of natural fibre (KF) that has been applied in a variety of industrial settings. Scientists, engineers, and researchers have recently become interested in natural fiber as a substitute component to improve the efficiency of the adsorption method. It is thought that using kenaf as an adsorbent is a creative and appealing technique....

Lockdown Tagout is a crucial aspect of occupational safety. In fact, it is essential to protect employees and workers near the machinery and equipment they use, maintain, and service. Still, there was information in this study regarding a LOTO system to create a LOTO quality manual at Sri Aman Fabrication and Industrial Trading Sdn Bhd. Observation...

This work aims to investigate the effect of black seed fiber as a reinforcing material for the fabrication of cornstarch-based biocomposite. The casting procedure was applied to fabricate the biocomposite at different concentrations of black seed fiber (3%, 6%, and 9%) and plasticizer mixture of fructose and glycerol set at a proportion of 30% (1:1...

Membrane technology research has advanced rapidly to treat wastewater, recycle contaminated water, and provide more freshwater. Because of their unique features, such as high porosity (up to 90%) and large specific surface area, electrospun nanofibrous membranes offer a lot of potential for use in membrane processes. When compared to other nanofibe...

Plastics and Non-biodegradable materials remain the most common material used by the food industry for packaging applications. As a result, the widespread use of these traditional plastics has resulted in a dangerous negative environment. Several studies have been conducted over the years to replace plastic packaging materials with environmentally...

Given the importance of renewable energy as it provides alternative energy sources over the traditional fossil fuel that is environmentally friendly, clean and renewable, this research aims to explore scholarly articles and books that present and investigate the challenges and barriers facing the implementation of renewable energy sources in Libya...

This paper outlines on the preliminary outcomes of pilot project aimed at exploring the issue related to managing of maintenance activity in the Malaysian Small and Medium Enterprises (SMEs). SMEs have been accepted as vital components of domestic industry development in many countries. However, the literature portrays that many of Malaysian SMEs p...

The tradition of fibre composite materials in energy absorbing tube applications has gained interest in structural collisions in the composite materials industry. Thus, the subject of this work is the experimental investigation to understand the effects of the failure initiator at the specimen’s edge, causing the increase in the specific absorbed e...

This paper aimed at investigating the actual maintenance practices that are being used in Malaysian industry. Primary data were collected using a questionnaire survey approach with 63 companies located in PasirGudang industrial area. Companies approached for this survey limited to a companies that have at least 100 employees. The collection of data...

Trabecular bone consists of complex webbing of plates and struts, in which the properties vary across anatomical sites. The substantial constraint is the reduction on discretization error will reduce time in computation. So it is significant to consider carefully the boundary condition effects when utilizing such a complex multiaxial loading mode....

The woven plain weave/epoxy hexagonal tubes’ capacity for energy absorption is investigated in present work. The experimental work was performed on composite hexagons with different hexagonal angles between 35° and 55° in aspect ratios L/t = 70 and 10° angular increments. Observation was made on how the configuration impacts the crash-worthiness be...

Uncertainty factors can be considered as major factors influencing experimental results. This article reviews the potential impact of uncertainty in manufacturing composite structures. It also describes the impact of the following factors on the testing process: Void content, curing time, tester calibration read error, interlinear bond, and mixed s...
