Opis:
About 94.8 per cent of Malaysian trade is depending on collective inter/intra-regional maritime networks. Straits of Malacca is an important strait and the only strait that connecting Indian Ocean and South China Sea which contributes to the nation's economic growth significantly. This strait plays a key character to enable the trade connection between east and west of the globe. In average, about 63,000 different types of vessels passing through the strait per year and the number of the vessels keep accelerating every year. Conversely, the introduction of Thai Canal to detour the trade voyage between Indian Ocean to South China Sea is expecting to reduce about three to four days journey time between these two passages. Although the development of this canal is predicted to provide substantial benefits to shipping lines, the grey area or disadvantages change to implications of this canal need to be explored especially on Malaysian trade and infrastructure. Therefore, a qualitative approach has been employed to achieve the aim of this paper. Face-to-face interviews with experts from various agencies had been conducted to gather information on the impact of Thai Canal on Malaysian trade and infrastructure. The outcome of this paper indicates that the implication of Thai Canal reduces the productivity of Malaysian seaports, transformation of seaports in northern region as a major hub of the nation, enforcing equal regional development between west and east coast Malaysia and administering dramatic progress on multimodalism in each state. The outcome of this research is important as an input for the preparation of Malaysian seaport system due to any significant changes in the trade route. Although, the development of Thai Canal reduce the overdependence on Malacca Straits, the impact of this this new canal will affects the trade performance of this region. Hence, this paper is significant to understand the implications that might occur to this nation due to dynamism of maritime logistics.

Opis:
This study evaluated the effect of milling speed and compaction pressure on the densification and morphology of the CuZn-Gr composite. The composite was prepared by using the powder metallurgy technique. The effect on the microstructural and compaction was determined based on different milling speeds. The different milling speeds involved were 175, 200, 225, and 250 rpm. Meanwhile, the different compaction pressures used in this study were 127, 250, 374, and 500 MPa. The properties of the milled powder gave the result to green density and densification parameters. The XRD pattern of Cu and Zn broadened as milling time increased.

Opis:
The purpose of the present article is the study of the effect of the gravity field on an initially stressed micropolar thermoelastic medium with microtemperatures. The analytical method used to obtain the formula of the physical quantities is the normal mode analysis. The comparisons are established graphically in the presence and the absence of gravity, initial stress and micropolar thermoelasticity. The main conclusions state that the gravity, initial stress and the micropolar thermoelasticity are effective physical operators on the variation of the physical quantities. The microtemperatures are very useful theory in the field of geophysics and earthquake engineering.

Opis:
The model of the equations of generalized thermoelasticity in a semi-conducting medium with two-temperature is established. The entire elastic medium is rotated with a uniform angular velocity. The formulation is applied under Lord-Schulman theory with one relaxation time. The normal mode analysis is used to obtain the expressions for the considered variables. Also some particular cases are discussed in the context of the problem. Numerical results for the considered variables are obtained and illustrated graphically. Comparisons are also made with the results predicted in the absence and presence of rotation as well as two-temperature parameter.

Opis:
In this study, the effect of sugar palm nanocrystalline cellulose (SPNCC) loading (0.00–0.10 wt %) on the electrical resistance, resistivity, and conductivity of SPS/SPNCC (SPS – sugar palm starch) nanocomposite films were evaluated. The experiments were conducted using the four-probe method and Ohm’s law, resistivity and conductivity equations were utilized to obtain the electrical properties. The results revealed that the resistivity values of SPS/SPNCC films were found to be in the range of 3.1 · 102 to 1.5 · 104 (Ω · cm).
Oceniono wpływ dodatku nanokrystalicznej celulozy otrzymanej z palmy cukrowej (SPNCC) (0,00–0,10% mas.) na rezystancję elektryczną, rezystywność i przewodnictwo folii wytworzonych z nanokompozytów (SPS/SPNCC) na bazie skrobi z palmy cukrowej (SPS). Badania przeprowadzono metodą czterosondową z zastosowaniem prawa Ohma; właściwości elektryczne określono na podstawie równań rezystywności i przewodności. Stwierdzono, że wartość rezystywności folii SPS/SPNCC mieści się w zakresie konduktywności od 3,1 · 102 do 1,5 · 104 (Ω · cm).

noise problem
Opis:
Transverse rumble strips (TRS) are a common choice to reduce vehicle speed and increase driver alertness on roadways. However, there is a potential trade-off using them on rural roadway due to the noise problem created when vehicles go over the strips. The present study investigated the noise level, spectral analysis, and the possible noise generation mechanism when the TRS is hit by a vehicle. Tenraised-rumbler (RR) and three-layer-overlapped (TLO) TRS were selected in this study as they have received complaints from the public. Results showed that RR generated a relatively higher noise and impulse at a low speed, and increased sound level in each octave band. Based on these results, RR may irritate human ears even when the vehicle travels at a low speed. It was found that RR increased all noise generation mechanisms of tyre-pavement interaction whilst TLO increased structural resonance, sidewall and surface texture vibration.
