In this work, a (CdO)0.94:(In2O3)0.06 film was developed on a glass substrate using Q- switching pulse laser beam (Nd:YAG; wavelength 1064 nm). The quantitative elemental analysis of the (CdO)0.94:(In2O3)0.06 thin film was achieved using energy dispersive X- ray diffraction (EDX). The topological and morphological properties of the deposited thin film were investigated using atomic force microscope (AFM) and field emission scan electron microscopy (FESEM). The I-V characteristic and Hall effect of (CdO)0.94 :(In2O3)0.06 thin films were used to study the electrical properties. The gas sensor properties of the film prepared on n-Si were investigated for oxidization and reduction gases.

Construction industry is second largest industry in gulf countries, that continuously rapidly growing. Similar to other countries around the world, construction industries in gulf region also facing problems due to oil industry uncertainties. Construction industry of gulf countries, construction material waste is getting higher concern. This paper aims to identify various factors in construction management causing construction material waste at Muscat, and Nizwa cities in Oman. Seventy-one (71) factors were collected from literature around the world and organized in structured questionnaire distributed amongst the construction experts focusing clients, consultants and contractors involved in the construction projects. The questionnaire was designed in such a way to collect construction waste causing factors in five major categories in (Design, Handling, Workers, Management, Procurement, and Site conditions). The collected data were analyzed by using Average Index method for each factor. Furthermore, construction material waste causing factors analyzed by individual response of client, consultant and contractor prospective. Analysis identified that 'frequent design changes'; 'wrong material storage'; 'worker's mistakes during construction'; 'poor supervision'; 'mistakes in quantity surveys'; and 'poor site conditions'; are highest significant causes in each category respectively. The result of this study is useful to create or/and improve guideline considering waste generated from construction industry, to avoid problems in looming construction. It is concluded that the government organizations or/and construction industry itself can develop or improve legislation for avoiding construction material waste.

To improve students' conceptual understanding depends on the question types asked by the teachers. This paper investigates to examine form four students' cognitive levels in Newton's Law based on Bloom's Taxonomy. The study sample consisted of 189 science stream students from three secondary schools in Kuala Kangsar, Perak. Researcher implemented Newton's Law questions as instrument to determine the three cognitive levels of the respondent which namely Knowledge, Comprehension and Application. The paper-pencil test was developed and administered on the subject. The data were collected and analyzed using the Statistical Packages for Social Science for Windows release 21 (SPSS Software). The findings show that the mean of the Knowledge, Comprehension and Application level is moderate.

The aim of this research is to determine the level of mastering Forces in Equilibrium topics according to thinking skill for Form Four Physics students. 189 Form Four Physics students from secondary school at Kuala Kangsar district in Perak involved in this research. All students are 16 years old. Questionnaire method has been conducted in order to perform this research. Descriptive statistics namely mean and standard deviation has been used in this research. The findings showed the level of mastering Forces in Equilibrium topics according to thinking skills was unsatisfactory.

The main focus of this study is to determine the attributes of willingness-to-pay (WTP) of the general public towards the entrance fee for using services in the Public Ecotourism Organization. Contingent Valuation Method is used to estimate the value of non-market good by adopting WTP approach. WTP is the maximum amount consumers are prepared to pay for a good or service and to enjoy recreational facilities. It measures whether an individual is willing to forego their income in order to obtain more goods and better services, and WTP is typically used for non-market goods. This study adopted questionnaires survey to examine the perception on the willingness to pay by visitors for the fees charged by the authorities for the services they provided. 100 local and international respondents among visitors involved in the study. The findings showed that National Park can give a new experience to visitors with beautiful natural landscape. However, the respondents perceived that road linkages of National Park are not proper and fee charged for boat services a bit too high. While, National Zoo is visited mostly to spend time and holiday with family due to attractive wildlife shows available daily. The authority however, needs to improve on hygienic aspect and perhaps to lower down the entrance fees. The attractiveness and shortcoming of the National Park and National Zoo are identified in order to suggest for improvements of services to public. As the economic growth, people will demand for better services and facilities or else willingness to pay will be affected. Thus, it is important for the government organizations to upgrade their services and facilities over time to fulfill the needs of the people.
