Purpose. Lantern tests and practical tests are often used in the assessment of prospective railway employees. The lantern tests rarely embody the actual colors used in signaling on the railways. Practical tests have a number of problems, most notably consistency of application and practicability. This work was carried out to provide the Railway LED

Response surface methodology (RSM) was used to determine the effects of high pressure homogenization (HPH) parameters (pressure and number of cycles) on the isolated yield, crystallinity, and diameter of kenaf bast cellulose nanofibers (CNF). Central composite design of experiments was utilized to determine the optimal pressure and number of cycles

A recent incident on the disappearance of Malaysia Airlines (MAS) flight MH370 has broken the hearts of people around the world. Joint international investigations have confirmed that the flight ended in the middle of the South Indian Ocean. However, till the day this work is written, no sign of wreckage, dead bodies or any shred of evidence could

Despite the tremendous number of mobile applications (apps) that developed using various implementation forms such as component, service, or app, user’s needs are unlike each other. Besides, mobile devices are characterized by heterogeneous software and hardware configurations. Developing customized mobile applications needs to explore and incorp

Cellulose nanomaterials processing for aerogel preparation has received considerable attention among the scientific community due to its fascinating properties. In this work, we report on the preparation of cellulose nanocrystals (CNCs) aerogel from wastepaper using a freeze-drying technique. Structural analysis of the cellulosic particles extracte

The present study focuses attention on the effect of Aspect ratio of the wing on roll damping moment derivative at various angles of attack and Mach number has been studied. It is found that rolling moment derivative increases with aspect ratio as well as with the angle of attack as the rolling moment derivative is linear function of aspect ratio a

Kidney stone is a disease that happens to many people in this world. There is possibility of a patient who has kidney stone will develop another. Thus, to prevent the recurrence of having kidney stone, there is an alternative treatment by using herbal plants. The proposed plants used in this experiment were based on some of the plants that have bee

Composite materials, incorporating noble metal and metal oxide nanoparticles, have attracted much interest as active substrates for biosensor electronics. These nanoparticles provide a viable microenvironment for biomolecule immobilization by retaining their biological activity with desired orientation and for facilitating transduction of the biore

Carbon Fibre Composites (CFC) are commonly used in aerospace, automotive and civil industries to manufacture high performance products which require high strength with low weight. They are usually produced to near net shape, however machining such as milling is frequently performed to achieve dimensional accuracy. This paper presents the effect of
