Mister atomizer technique or so called spray pyrolysis has been applied to deposit CuI thin films on amorphous substrate. The effects of substrate temperature (RT- 200°C) on their electrical and optical properties were studied. The physical characteristics of sprayed CuI were determined by field emission scanning electron microscopy (FESEM), current voltage (I-V) measurement and UV-VIS-NIR spectrophotometer. The nanoparticle of CuI was observed at different deposition condition. The effect of substrates temperature on thickness and resistivity proved that both decreases as the substrate temperature increased. This was caused by the increase of carrier concentration at higher substrate temperature. The transmittance and absorption coefficient was measured and then the energy gap was determined which shows the direct transition of n=2. The optimum band gap observed here is 2.75 eV at 150°C of substrate temperature.

Layer-by-layer ZnO nanoparticles thin films were deposited using sol-gel spin coating technique. Zinc acetate dihydrate, 2-methoxyethanol and monoethanolamine were used in the ZnO solution. Different numbers of film layers were employed to study their effects to the physical, electrical and optical properties of the thin films. XRD patterns showed that the films were single crystalline with highly c-axis orientation for films with higher numbers of deposition layers. Morphology studies revealed that the grain sizes increased with the number of layers. Resistivity of the film decreased with the increased number of layers with minimum value of 15.5 Ω.cm given by 6 layers film. The PL spectra exhibit highest UV emission for 6 layers film due to high crystalline quality of the thin film.

This study aimed to develop an optimal condition of Cu(II) extraction from aqueous solution using cooking palm oil as a potential organic solvent. Response surface methodology (RSM) based on central composite rotatable design (CCRD) was used to optimize the two important process variables namely pH equilibrium (pHeq) and D2EHPA concentration for the Cu(II) extraction. The adequacy of the model was examined, and it was found to be statistically significant. The optimum condition for the Cu(II) extraction was as follows: 4.48 pHeq and 76.00 mM D2EHPA concentration. The optimum predicted percentage Cu(II) extraction was 99.58% and the actual value was 98.08%. The above results shows that the RSM study based on CCRD is adaptable for Cu(II) extraction studied and thus cooking palm oil are potential as greener substitutes for the conventional petroleum-based organic solvents.
以棕榈油为有机溶剂，研究了从食用油水溶液中提取铜(II)的最佳工艺条件。采用基于中心复合旋转设计(CCRD)的响应面法(RSM)对铜(II)提取的pH平衡(pHeq)和D2EHPA浓度两个重要工艺变量进行了优化。对模型的充分性进行了检验，发现有统计学意义。铜(II)的最佳提取条件为:4.48 pHeq, 76.00 mM D2EHPA浓度。Cu(II)的最佳萃取率预测值为99.58%，实际萃取率为98.08%。上述结果表明，基于CCRD的RSM研究适用于所研究的Cu(II)提取，因此蒸煮棕榈油具有替代传统石油基有机溶剂的绿色潜力。

The aim of this study is to compare the adsorption capacity of Remazol Brilliant Blue R (RBBR) onto three different coal-based adsorbents namely, untreated bottom ash (BA), H2O2-treated BA and physical-activated BA. The removal of RBBR was determined over a concentration range of 50-500 ppm using batch adsorption experiment at room temperature. The percentage removal of RBBR was decreased with the increase of initial concentration. The comparison of percentage removal of RBBR onto the various adsorbents followed the trend: physical-activated BA >; H2O2-treated BA >; untreated BA. In addition, the adsorption isotherm constant reveals that physical-activated BA gives the highest adsorption capacity of RBBR. Result shows that the adsorption mechanisms of RBBR onto the adsorbents studied are well presented by both Langmuir and Freundlich isotherms.
本研究的目的是比较Remazol Brilliant Blue R (RBBR)在三种不同的煤基吸附剂上的吸附能力，即未经处理的底灰(BA)、h2o2处理的BA和物理活化的BA。在50 ~ 500ppm的浓度范围内，采用常温间歇吸附法测定了RBBR的去除率。RBBR去除率随初始浓度的增加而降低。不同吸附剂对RBBR去除率的比较结果显示:物理活化BA >;h2o2处理BA >;未经处理的英航。吸附等温线常数表明，物理活化BA对RBBR的吸附能力最高。结果表明，Langmuir等温线和Freundlich等温线都很好地描述了RBBR在吸附剂上的吸附机理。

This study was designed to evaluate a simple equation to estimate an annual interception lost. To design the equation, the input of the equation was modified to a very high resolution data. Statistical relationship between precipitation, temporal resolution and rainfall intensity was determined. Minimum inputs require to be applied in the equation are annual precipitation and the depth of storage capacity of the selected area. To validate the equation, the equation has been applied to several locations in the world including Malaysia. Performance of the equation was evaluated by BIAS efficiency.

Technology can help persuade people to change their attitudes or behaviors. Elderly population is not familiar with information technology but e-Health services can help people maintain a healthy lifestyle. In order for the elderly to get benefits from e-Health services, they need to change their attitudes or behaviors. To make this change, it is necessary to persuade the elderly to embrace the use of smartphone. This research investigated factors that influence the elderly's intention to use e-Health services via a smartphone. According to the UTAUT model, the factors that influence the user's intention to use e-Health services are as follows: Performance Expectancy, Effort Expectancy, Social Influence, and Facilitating Conditions. Although the UTAUT model has been widely used to explain user acceptance and use of technology, lack of experience with recent technological advancement and age related deficiencies makes it less attractive for the elderly to adopt new technologies such as the smartphone. This is directly related to the elderly's perception of whether new technology can benefit to their lives. Hence, in this study, the UTAUT model has been extended to include a `Perceived Value' factor. The proposed model identified factors influencing the elderly's intention to use e-Health services via a smartphone. It is found that `Perceived Value' has a strong significance on the elderly's intention to use smartphone, followed by Facilitating Conditions and Effort Expectancy. In contrast, Performance Expectancy and Social Influence did not have a significant influence on intention. With the proposed model, it is possible to develop better e-Health services to meet the needs of the elderly based on widely available smartphones.

This study investigated students' experiences in two types of instructional strategies (i.e., fully-guided and partially guided) and their learning experience patterns from the beginning towards the end of the computer-based interactions. An empirical study was performed on 41 students from a public university in Malaysia using two types of computer-based systems for learning Basic Computer Networks. The students' learning experiences were evaluated at three different stages of the computer-based learning sessions using self-report technique. The results showed that the students' learning experiences were changing over the period of the computer-based lessons either in positive or negative ways. The directions of changes were mainly influenced by the students' Information Technology (IT) prior knowledge. The results of this study suggest that computer-based guided learning systems should consider students' background of knowledge in their design to achieve effective learning. Further, the combination of the fully-and partially-guided features may create an adaptive computer-based learning system.

In order to ensure the ambulance arrival to patient is within the targeted time, ambulance availability must be ensured and the time taken to arrive can be controlled. Optimal route that able to provide shortest distance must be determined. Thus, an interface is developed to help the ambulance providers in sending the ambulance to a specified ambulance station and emergency site. The interface for the ambulance routing is designed to give shortest path and shortest distance (in km). The results obtained were programmed using C# (pronounced as C sharp) software and the A* algorithm utilized as the engine to determine the shortest distance for the ambulance in the study area.

This paper proposed a new sensitivity analysis approach using the linguistic hedges in fuzzy environment. At the first place, the linguistic hedge was briefly described with emphasis on the two types, namely concentration and dilation. Afterwards the power of concentration or dilation was employed to represent the strength of the hedges A fully linguistic variable was used to assess the entire investigation attribute in a case study. Lastly, the power of both hedge will changed into one level up or down from the basis power for testing purposes The results show that, changing one level up or down power of the hedge cause only small variations of the performance values and the final ranking remains unchanged. Thus, it shows that our proposed approach can be utilised to derive the robust model for decision-making purposes.
