Advanced oxidation process (AOPs) are technologies based on the intermediacy of hycroxyl radical and other radicals to oxidize recalcitrant, toxic nad no biodegradable cpmpounds to various by- products. In this paper, Oxytetracycline hydrochloride (OTC) was degraded inside a UV-H2O2 system which utilize hydroxyl radical generated from H2O2 to attack OTC. Concentration of H2O2, temperature and pH was varied in this experiment. To monitor OTC degradation, TOC and UV-VIS spectra analysis were carried out. Constant OTC concentration at 250 ppm was used. About 93.06% of TOC removal was achieved at 40°C and 1 eq mole ratio H2O2 to OTC. After 180 min irradiation, UV-Vis spectra of OTC have shown total disappearance of OTC peak. HPLC analyses has shown about 93.08% of OTC were degraded after 180 min irradiated inside UV-H2O2 system.

The calorific value (CV) of syngas produced from gasification of solid biomass varies depending on the type of biomass as well as the gasifier type. Moreover, the interdependent operating conditions like reactor temperature, moisture content of biomass, and air fuel ratio play a major role in the composition as well as calorific value of syngas. The gasification of oil-palm fronds (OPF) is not studied in the past, and there is no previous work on the expected composition or CV of syngas. Therefore, it is found necessary to predict the CV of syngas for different operating conditions, in order to be able to exploit the energy reserve of this abundantly available biomass waste. This paper presents the prediction of CV of syngas produced from downdraft gasification of OPF by making use of ASPEN PLUS simulation model. The results of the simulation showed how the CV varies with operating conditions: moisture content, air fuel ratio and oxidation zone temperature. The result of the model showed that the CV predicted vary in the range of 4.05 to 4.35 MJ/m3 for increase in the oxidation zone temperature from 500 to 1200°C. In addition, the CV showed a decrease with moisture content. Moreover, a closely similar pattern of change in CV is obtained, through comparison with results reported in literature for gasification of other types of biomass feedstock.

Usability evaluation is a process to assess system functionality and user's experience. Many usability evaluation methods have been proposed for different types of systems. Haptic systems are unique in a way that these systems deal with sense of touch i.e. haptic feedback. There is a lack of usability evaluation methods/framework for these systems. This paper presents the research approach towards the development of such framework. The adoption of well known research methods for the study ensures the reliability of findings and the development of framework. This research approach may helpful for others to conduct similar studies.

As the interest in cloud computing grows ranging from individuals to corporates and governments, efficient service discovery has become paramount for satisfactory user experience. Due to the distributed nature of cloud services we propose an unstructured P2P discovery model for service discovery in cloud environment. Traditional query routing heuristics in P2P systems functions purely at the overlay layer. These heuristics do not posses knowledge of the underlying physical topology which leads to performance bottleneck. This paper addresses this problem by proposing a novel P2P model with the awareness of the underlying network in order to leverage the performance of distributed service discovery in cloud environment. This is achieved by applying the concept of Application Oriented Networking (AON), which has the capability of message level intelligence. Our claim is proved by results obtained through prototype simulation.

Chemical enhanced oil recovery methods are field proven techniques that improve efficiency and effectiveness of oil recovery. High oil prices and dropping reserves alternative has inspired interest in chemical flooding technologies, particularly for application in mature water flooding. The more concern about this technique is surfactant development. A new sulfonate surfactant from non-edible vegetable oils is developed as an alternative source of petrochemical feedstock which is not desirable due to the environmental problems and high cost. The sulfonate surfactant was synthesized from C16–18 feedstock and evaluated in phase behavior, IFT for its capability to enhance oil recovery. The feedstock is composed mostly of unsaturated fatty acid derived from jatropha curcas oil which can be converted to fatty acid methyl ester. The methyl ester is epoxidized and hydrolyzed to hydroxyl groups, which subsequently were sulfonated to form a product named Methyl Ester Sulfonates (MES) or α-sulfonated methyl esters. The phase behavior between crude oil (37.7 deg API) and surfactant solution show the ability of the surfactant to create clear microemulsion free of gel, liquid crystals, and macroemulsiuon and also rapid equilibration to low-viscosity emulsion. Based on IFT experiments optimum surfactant concentration determine as 2500 ppm which result in a lowest possible IFT around 0.078 mN/m in presence of Na2CO3 as alkali. The results illustrate the possibility of developing new surfactants from vegetable oils which can obviate the need for using petrochemicals substances.

Semantic Web provides precise, timely, searchable and well-define information across different sources of data. However, there is need of solving the problem of interoperability due to everyday increase of data from different sources. Whereby, the resourceful information or data integration between human and machines are needed. Thus, more precisely, this paper addresses an ultimate problem of integrating and utilizing the accurate data on information systems. The proposed methodology of this paper includes: (1) grounded theory that focuses on particular interaction between human and machines, (2) developing the analysis; the research introduces the Software Development Life Cycle (SDLC) approach, from the development to implementation stages, (3) sources of data; for state-of-the-art research, we propose to use MetOcean (Meteorological and Oceanographic) data, and (4) Research instrument which is to set our research into practice where we will build Semantic Web application using Franz AllegroGraph and use SIMILE (Semantic Interoperability of Metadata and Information in Unlike Environments). Finally, we provide the Ontology model of the for the state-of-the-art research in meteorological and Oceanographic domain.

Undoubtedly, marketing is an important tool to position and brand Higher Education Institutions (HEIs). Nowadays, higher education is facing big challenges, which have made a lot of HEIs interested in attracting more students. Likewise, education marketing division in the Ministry of Higher Education (MOHE) Malaysia was set up for the purpose of promoting Malaysian higher education. In recent years, with the rising importance of social media, many promotional tools like traditional print and broadcast media have faced major challenges, as many newspaper and television channels lost their audiences. Overwhelmingly, the majority of Malaysian HEIs are beginning to embrace some forms of social media for promotional purposes. This research is mainly descriptive and explanatory, and partially exploratory in nature. The collected data will be qualitative and quantitative based on survey questionnaires and semi-structured interviews on the application of social media in promoting Malaysian higher education. Beside these methods, secondary data collection from an analysis of Malaysian HEIs' online social communities will be conducted.

Rivers contain a large amount of sediment along with flowing water. It is vital to know the sediment discharge in a river while designing different water resources engineering projects. In this study, suspended sediment discharge has been predicted using a radial basis function (RBF) neural network. Time series data of water discharge and suspended sediment discharge of Pari River, in Perak, Malaysia has been used for modeling the network. The most common radial basis function, called the Gaussian function has been used for modeling the RBF neural network. Three different statistical performance measures namely the root mean square error (RMSE), coefficient of determination (R2) and coefficient of efficiency (CE) were used as performance evaluation criterion for the model. Results obtained from the RBF model are satisfactory and was found that RBF is able to predict the nonlinear behavior of suspended sediment discharge of Pari River.
