Investigation On The Behavior Of Rigid Polyvinylchloride Pipes Subjected To Uniaxial Compression Loads, Alhamati Abdullah Ali Nasser, Ghazali Abdul Halim, Norzaie Jamalodin 2017 Universiti Brunei Darussalam

Investigation On The Behavior Of Rigid Polyvinylchloride Pipes Subjected To Uniaxial Compression Loads, Alhamati Abdullah Ali Nasser, Ghazali Abdul Halim, Norzaie Jamalodin

ASEAN Journal on Science and Technology for Development

The objective of this research was to investigate the capability of rigid Polyvinylchloride (PVC-U) pipes to sustain axial loads. The behavior of PVC-U pipes specimens subjected to short-term uniaxial compression loads were experimentally investigated. Results of the load-displacement tests on pipes of different wall thickness, diameter, and specimen heights were recorded. The experimental test results show that the PVC-U pipes are capable of supporting loads greater than the required design load (3.4 kN). Increasing the pipe specimen height decreases the pipe strength for supporting the axial loads. Euler buckling was observed in the pipe specimens with small diameter and long …

Role Of Sawdust In The Removal Of Iron From Aqueous Solution, Senin H.B., Subhi O., Rosliza R., Kancono N., Azhar M.S., Hasiah S., Nik W.B. Wan

ASEAN Journal on Science and Technology for Development

Sawdust, inexpensive material has been utilized as an absorbent for the removal of iron from aqueous solution for their safe disposal. The adsorption experiments of untreated sawdust (SD) and treated sawdust (SDC) have been carried out at room temperature using the batch test. The Langmuir and Freundlich isotherms were used to observe sorption phenomena of sawdust in the removal of iron. The results indicate that the sawdust was capable in removing iron in aqueous solution. The results have shown that the Langmuir isotherm was found well fitted into the experimental data as compared to the Freundlich isotherm. It was found …

Improving The Baculovirus Expression Vector System With Vankyrin-Enhanced Technology, Kendra H. Steele, Barbara J. Stone, Kathleen M. Franklin, Angelika Fath-Goodin, Xiufeng Zhang, Haobo Jiang, Bruce A. Webb, Christoph Geisler

Entomology Faculty Publications

The baculovirus expression vector system (BEVS) is a widely used platform for the production of recombinant eukaryotic proteins. However, the BEVS has limitations in comparison to other higher eukaryotic expression systems. First, the insect cell lines used in the BEVS cannot produce glycoproteins with complex‐type N‐glycosylation patterns. Second, protein production is limited as cells die and lyse in response to baculovirus infection. To delay cell death and lysis, we transformed several insect cell lines with an expression plasmid harboring a vankyrin gene (P‐vank‐1), which encodes an anti‐apoptotic protein. Specifically, we transformed Sf9 cells, Trichoplusia ni High Five …

Effectiveness Of Selected Entomopathogenic Fungi In Packed Rice Grain At Room Temperature Against Corcyra Cephalonica Stainton, Samodra Hendrawan, Ibrahim Yusof Bin 2017 Universiti Brunei Darussalam

Effectiveness Of Selected Entomopathogenic Fungi In Packed Rice Grain At Room Temperature Against Corcyra Cephalonica Stainton, Samodra Hendrawan, Ibrahim Yusof Bin

ASEAN Journal on Science and Technology for Development

Eight isolates of entomopathogenic fungi were evaluated as dried conidia against the rice moth, Corcyra cephalonica. In bioassays two isolates of Beauveria bassiana (BbGc and BbPs) and one isolate of Metarhizium anisopliae (MaPs) consistently gave high mortality to C. cephalonica larvae. Formulations in either kaolin, talc or tapioca flour (20 % w/w a.i.) thoroughly mixed with long grain rice in plastic cups (8 cm diameter by 5 cm) gave complete larval mortality by the 12th day of treatment. However, in general those formulated in kaolin and talc were more efficacious and faster to kill compared to those formulated in tapioca …


A Fuzzy Logic Based Method For Analysing Test Results, Vinh Le Xuan, Quan Tran Hong 2017 Universiti Brunei Darussalam

A Fuzzy Logic Based Method For Analysing Test Results, Vinh Le Xuan, Quan Tran Hong

ASEAN Journal on Science and Technology for Development

Network operators must perform many tasks to ensure smooth operation of the network, such as planning, monitoring, etc. Among those tasks, regular testing of network performance, network errors and troubleshooting is very important. Meaningful test results will allow the operators to evaluate network performanceof any shortcomings and to better plan for network upgrade. Due to the diverse and mainly unquantifiable nature of network testing results, there is a needs to develop a method for systematically and rigorously analysing these results.In this paper, we present STAM (System Test-result Analysis Method) which employs a bottom-up hierarchical processing approach using Fuzzy logic. STAM …

Timing Synchronization For Mc-Cdma Systems Using A Time-Multiplexed Synchronization Channel, Ky Pham Hong, Long Nguyen Duc

ASEAN Journal on Science and Technology for Development

In this paper, we present a synchronization algorithm for Multi-Carrier CDMA (MC-CDMA) systems using a time-multiplexed synchronization channel. The simulations results show that a system using proposed algorithm has much higher timing detection probability than using other algorithms, especially in exponential decay multipath fading.

ASEAN Journal on Science and Technology for Development

Bioassay guided fractionation led to the isolation of a new triterpene glycoside, holothurinogenin B (1) along with three known compounds, holothurin B (2), holothurin A (3), and holothurin A2 (4), from the methanol extract of the Vietnamese sea cucumber Holothuria scabra. Their structures were deduced from the spectral analysis (1D-NMR, 2D-NMR, MS) and chemical evidences.


Characteristics Of Solid-State Calcium Ion Sensors Based On Photocurable And Selfplasticising Polyacrylate Matrices, Heng Lee Yook, Hall Elizabeth A.H. 2017 Universiti Brunei Darussalam

Characteristics Of Solid-State Calcium Ion Sensors Based On Photocurable And Selfplasticising Polyacrylate Matrices, Heng Lee Yook, Hall Elizabeth A.H.

ASEAN Journal on Science and Technology for Development

New membrane materials based on cross-linked poly(n-butyl acrylate) (nBA), have been used successfully as calcium ion-selective membranes. These membrane materials possess selfplasticising property and hence do not require plasticisers. The photocurability and good adhesion characteristics of these polymer matrices enable workable solid-state calcium ion sensors to be fabricated by simple photocure procedures employing the calcium ionophore ETH5234 and a lipophilic additive as ion sensing components. The calcium ion-selectivity of the sensors can be controlled by varying the chemical composition of the photocured membrane. An optimum amount of the cross-linker 2,2-hexanedioldiacrylate (HDDA) and the incorporation of n-heptyl acrylate (nHA) led to …


The Safety Of Building Structures Subject To Unusual Natural And Man-Made Disasters, Pho Nguyen Van 2017 Universiti Brunei Darussalam

The Safety Of Building Structures Subject To Unusual Natural And Man-Made Disasters, Pho Nguyen Van

ASEAN Journal on Science and Technology for Development

Previously, we often use the statistical data on natural disasters and mathematical tools such as probabilistic theory, mathematical statistics and random processes to express and analyze natural disasters' phenomena when dealing with the safety problem of building structures subject to natural disasters. However, due to unusual change of the global climate, natural disasters have changed essentially the intensity, frequency and the appearing time so we cannot rely on the statistical data on natural disasters in the past to do that. Therefore, renovation of the thought on selection of plans, calculation, design, and evaluation of safety of building structures to accommodate …

ASEAN Journal on Science and Technology for Development

An efficient lighting system (Compact 3U) was successfully applied to the micropropagation of gloxinia and potato plants. To compare the in vitro growth of plantlets under Neon and Compact 3U lighting systems, gloxinia and potato shoots were cultured on suitable media at different light intensities: (1) 45 µmol m-2s-1 (under Neon lighting system as a control); (2) 45 µmol m-2s-1, (3) 60µmol m-2s-1, and (4) 75 µmol m-2s-1 (under Compact 3U lighting systems). The results obtained after 3 weeks of in vitro culture and 6 weeks of acclimatization in a greenhouse showed that the growth of plantlets cultured under the …
