Rapid Detection Of -Thalassemia Mutations In Thailand Using Multiplex Arms, Shimbhu D., Mirasena S., Sanguansermsri M., Sanguansermsri T. Nov 2017

Rapid Detection Of -Thalassemia Mutations In Thailand Using Multiplex Arms, Shimbhu D., Mirasena S., Sanguansermsri M., Sanguansermsri T.

ASEAN Journal on Science and Technology for Development

The number of mutations underlining b-thalassemia generate a wide variety of different clinical phenotypes. An understanding of the genotype is important for medical personnel in order to provide proper counseling to patients and their families. Characterization of these mutations should aid the planning of a prenatal diagnosis program for bthalassemia. The heterogeneity of the mutations makes it difficult and time consuming to identify the mutation in some individuals. We developed a single-tube multiplex amplification refractory mutation system (multiplex ARMS) to identify common ethnic- specific b-thalassemia mutations. Confirmation of multiplex ARMS results was carried out using direct sequencing. Three thousand three …

Microbial Diversity In Trace Water Of Jet Fuel In Vietnam, Hien Lai Thuy, Hang Pham Thi, Nga Vuong Thi, Hai Hoang, Yamaguchi Nobuyasu, Tani Katsuji

ASEAN Journal on Science and Technology for Development

Microorganisms in petroleum product, including jet fuel, have been found by some English andAmerican authors since the 20’s of the last century. In 1958, after Bakanaukas isolated many microorganisms in jet fuel JP4, this topic was especially concentrated. Most of microorganisms living in jet fuel are able to degrade hydrocarbon of the fuel to obtain energy and carbon source for their growth. The presence of microorganisms in jet fuel not only brings about the lost of fuel in store process, but also briefly changes the component and structure of jet fuel. Moreover, the products of their metabolism, such as organic …

Potassium Permanganate As Oxidant In The Cod Test For Saline Water Samples, Goh Chin-Ping, Lim Poh-Eng Nov 2017

Potassium Permanganate As Oxidant In The Cod Test For Saline Water Samples, Goh Chin-Ping, Lim Poh-Eng

ASEAN Journal on Science and Technology for Development

The objective of this study is to investigate the feasibility of applying potassium permanganate (KMnO4) as the oxidant in the COD test for highly saline water samples. Initially, the COD values of various glucose standard solutions were determined by three methods, namely the standard closed reflux dichromate (CODCr), the acidic permanganate (CODMn) and the alkaline permanganate (CODOH) methods. The results showed that at COD values lower than 20 mg/L, the standard dichromate method was not applicable due to its poor precision (RSD > 10%). The CODOH method was less effective compared to the CODMn method as the recoveries were 0.71 and …

Structural Characterization Of Agar Extracted From Six Red Seaweed Species Growing In The Coast Of Vietnam, Van Tran Thi Thanh, Ly Bui Minh, Buu Ngo Quoc, Kinh Chu Dinh

ASEAN Journal on Science and Technology for Development

Polysaccharides extracted from six red seaweed species growing in Vietnam have been studied. Characterisation of their structure by chemical and spectroscopic methods showed that all of them have a basic repeating structure of alternating 3-linked b-D-galactopyranosyl and 4-linked 3,6-anhydro a-L-galactopyranosyl units with substituted methyl ether groups. The native agar offers only weak gelling abilities owing to the 4-linked a-L-galactopyranosyl 6-sulfate as its precursor. Conversion of this unit into the corresponding 3,6-anhydride by treating with hot alkali generally led to gel strength increasing. The agars from G. fisheri and G. firma are poorly substituted, while those from G.asiatica, G.tenustipitata and G. …


Fault Location On A Distribution Feeder Using Fault Generated High Frequency Current Signatures, Hizam Hashim, Crossley P.A. Nov 2017

Fault Location On A Distribution Feeder Using Fault Generated High Frequency Current Signatures, Hizam Hashim, Crossley P.A.

ASEAN Journal on Science and Technology for Development

This paper describes how the fault generated travelling waves detected in the current signals at a single location on a distribution feeder can be used for fault location. The method identifies the fault section and the probable location of the fault by comparing the relative distance of each “peak” in the high frequency current signals to the known reflection points in the distribution feeder. The probable fault location is then used within a transient power system simulator that models the actual network. The resulting simulated current waveforms are then cross-correlated against the original signal. If the estimated fault location is …
