Comparison of processing and mechanical properties of polypropylene/recycled acrylonitrile butadiene rubber/rice husk powder composites modified with silane and acetic anhydride compound
(SAGE Publications Ltd, 2014-12)
Polypropylene (PP)/recycled acrylonitrile butadiene rubber (NBRr)/rice husk powder (RHP) composites were fabricated with silane and acetic anhydride (Ac) treatment agent. The in situ formed RHP-filled PP/NBRr composites ...
Performance evaluation of okra (abelmoschus esculentus) as coagulant for turbidity removal in water treatment
(Trans Tech Publications, 2014)
The objective of this study is to evaluate the performance of turbidity removal in water by using Okra (Abelmoschus esculentus) as natural coagulant. The coagulation active agent in various Okra sections was extracted with ...
Landfill leachate treatment using SSF-FWS constructed wetland planted with Limnocharis flava and Eihhornia crassipes under different hydraulic loading rate
(Trans Tech Publications, 2014)
A laboratory-scale study was conducted using a combination of SSF and FWS constructed wetland planted with Limnocharis flava and Eichhornia crassipes to treat landfill leachate. The effects of hydraulic loading rate (HLR) ...
Physicochemical properties of pyrolitic carbon black from waste tyres
(Trans Tech Publications, 2014)
Waste tyres which are mainly generated from automotive industries have become a major environmental problem to the local authorities, the tyre industries and tyre dealer. When tyres are no longer usable due to worn-out, ...
COD removal from anaerobically treated palm oil mill effluent (AT-POME) via aerated heterogeneous Fenton process: Optimization study
(Elsevier Ltd, 2014-04)
Due to the extremely high content of organic pollutants, palm oil mill effluent (POME) requires multiple stages of treatment. At the primary stage, because of the high loading of organics, anaerobic treatment method was ...
Mean imputation techniques for filling the missing observations in air pollution dataset
(Trans Tech Publications, 2014)
Almost all real life datasets consist missing values. These are usually due to machine failure, routine maintenance, changes in siting monitors and human error. The occurence of missing values requires special attention ...
Minimum input variances for modelling rainfall-runoff using ANN
(Penerbit UTM Press, 2014)
This paper presents the study of possible input variances for modeling the long-term runoff series using artificial neural network (ANN). ANN has the ability to derive the relationship between the inputs and outputs of a ...
Effects of elevated temperatures on the thermal behavior and mechanical performance of fly ash geopolymer paste, mortar and lightweight concrete
(Elsevier, 2014-01)
This paper reports a comparative study of the influence of elevated temperature on geopolymer paste, mortars and lightweight aggregate geopolymer concrete (LWAGC) systems made by using fly ash (FA) as only source material. ...
Microstructure study on volcano ash geopolymer aggregate at different sintering temperature
(Trans Tech Publications, 2014)
Recent research shows that the by-product materials such as fly ash can be used as raw material in producing aggregates and lightweight aggregates. The usage of this material can improve the quality of the aggregates ...
Flexibility of supply chain in Industrialised Building System (IBS)
(EDP Sciences, 2014)
It is irrefutable that the construction industry is in need of a highly technological construction method or system for the simple aim of giving it a push it deserves. In Malaysia this technologically enhanced method is ...
