The lattice parameter of PbZrO3 (PZ) was calculated as a reference compound and the results show an accuracy values relative to the experimental values. In this first-principle calculations, the exchange-correlation functional is based on LDA-CAPZ which give underestimate in structural lattice parameters with typical errors of 2%. The elastic constants and their pressure dependence were calculated up to 30 GPa, and independent elastic constants (C11, C12, and C44), bulk modules, B are obtained and analyzed. Density of state (DOS) studies reveal that the anion O 2p, cation Sn 5p/Pb 5p and Zr 4d states of SZ and PZ play an important role which correspond to the top of valence states and bottom of conduction band. Meanwhile, direct band gap at X-X point is respectively obtained for both SZ and PZ along the higher symmetry direction in the Brillouin zone. The born effective charges (BEC) values of Sn and Zr (in SZ) have respectively been found to be +4.26 and +7.53. This is attributed to the bond charge response to the displacement caused by the strong covalency between cation orbital and O 2p. Results reveal anion O 2p, cation Sn 5p and Zr 4d states have also played an important role in optical transition in which they respectively correspond to the top of valence states and bottom of conduction band. The results of prototype SZ were compared and showed in good agreement with the calculated results of PZ.","PeriodicalId":444674,"journal":{"name":"2012 IEEE Colloquium on Humanities, Science and Engineering (CHUSER)","volume":"24 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116639283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two types of photocatalysts were prepared namely Zn/ZnO and Zn/ZnO/TiO2. Zn/ZnO film was prepared by anodic oxidation of zinc in NaOH with various concentrations. Zn/ZnO deposited with TiO2 photocatalyst was prepared by electrodeposition method. It was found that the optimum concentration for the electrolyte solution (NaOH) was 0.8 M. The pH value of the sample solution had influenced the photocatalytic activity of Zn/ZnO/TiO2 plate in degrading BTX solution. The most suitable pH for the degradation of BTX was pH 6. The most effective degradation of BTX solution using Zn/ZnO/TiO2 plate is 91.54% degradation under four hours of UV irradiation time. The Field Emission Scanning Electron Microscopy (FESEM) and Energy-dispersive X-ray spectroscopy (EDX) were applied to study the surface morphology of the Zn/ZnO plate and Zn/ZnO/TiO2 photocatalysts. The large porous surface of Zn/ZnO plate prepared by using 0.8 M NaOH contributed to large amount of TiO2 deposited onto the surface of the photocatalyst and excellent performance of Zn/ZnO/TiO2 on UV-Induced degradation of BTX solution.","PeriodicalId":444674,"journal":{"name":"2012 IEEE Colloquium on Humanities, Science and Engineering (CHUSER)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125893614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional physical and chemical treatments are restricted because of their technical and economical constraints. One of the possible solutions is introducing biosorption method in heavy metals removal. The present study aim to evaluate the potential of Pleurotus ostreatus (P.ostreatus) fungus in the removal of Fe(II), Pb(II), Zn(II) and Cu(II) ions from single and multi metal synthetic solution. Throughout the study, the best operating treatment process were found when the pH of the solution was above 4 with 80.52, 45.20, 12.47 and 2.88% removal for Fe(II), Cu(II), Pb(II) and Zn(II); agitation speed of 150 rpm and temperature of 25°C. It was found that the removal of heavy metals is lower from single than multi metal solution. The biosorption preference order of P.ostreatus is Fe(II) > Cu(II) > Pb(II) > Zn(II). The results obtained validate that biosorption by P.ostreatus is a potential method in replacing conventional heavy metal removal and in the wastewater treatment.","PeriodicalId":444674,"journal":{"name":"2012 IEEE Colloquium on Humanities, Science and Engineering (CHUSER)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123273992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this research, Phonic Reading Technique and Multisensory Approach are blended with interactive multimedia, which incorporates multimedia elements such as text, graphics, video, and animation. The manner of applying those techniques in “Bijak Membaca” is discussed. The contents of this application are specifically designed to visualize letters, words, sentences, and pronunciations in the Malay language for dyslexics, aged 7–8 years, with awareness of their characteristics. In order to evaluate the design of its content, heuristic testing is conducted among multimedia lecturers and IT undergraduates. The result reveals that the contents are well designed with the inclusion of Phonic Reading Technique, Multisensory Approach, and suitable multimedia elements.

Long term wave data is important for the design of coastal structures and for the calculation of sediment transport rates. In this study a third-generation wave model has been used to generate 10 years (1992–2001) of wave climate atlas for the Persian Gulf. The European Center for Medium Range Weather Forecasts (ECMWF) wind field data after some modifications, and compiled bathymetry data from few sources, were employed as the input data of the model. In situ and satellite wave datasets were used to calibrate the model, and the validation of the results. The results show that the higher waves have a better accuracy over the whole Persian Gulf, and the overall accuracy is more than 80% for all simulated data. All the datasets (input and output data) were stored in a GIS-based software that was developed to provide a user friendly environment for data visualization and extraction. A multidimensional data model was developed for data management and visualization of numerical model results in the GIS environment.
