Maslawati Mohamad, Dafita Dwi Lestari, Azizah Mohd Zahidi, Mohd Effendi Mohd Matore
Creative Education (CE) , 2019, DOI: 10.4236/ce.2019.101010
Abstract:
Mastering a language not only involves four language skillslistening, speaking, reading, and writingbut also mastering the grammar and vocabulary of the language. This research was intended to investigate the perceptions of Indonesian undergraduates and their lecturers at the Islamic University of Riau toward the use of Socrative in grammar class specifically tenses. This study employed a quantitative research design. The respondents were 34 sixth-semester undergraduates who were randomly chosen and two grammar lecturers at the English Department of Islamic University of Riau in the academic year 2016/2017. The questionnaire was adapted from the technology acceptance model (TAM) by Davis, which consists of two specific variables: Perceived usefulness and perceived ease of use. Before the questionnaire was employed in this study, a pilot study was carried out to ensure the validity and reliability of the instrument. The findings of the research show the majority of respondents have positive perceptions toward Socrative. The students and lecturers provide positive responses with regard to “perceived usefulness and ease of use” of Socrative in grammar class. It is hoped that this tool not only could be used in grammar class but also in all aspects of English language learning. It is also expected that this research could assist Indonesian educators to teach more creatively.

Abstract: The incidence of dengue in Malaysia has shown an increasing trend since the year 2000. Vector control is the primary approach for dengue control in Malaysia. There is an urgent need for new or modified approaches such as the residual spraying on the outer walls that can potentially last long enough to control the Aedes population, particularly in the outbreak-prone areas. In this field study, we conducted outdoor residual spraying (ORS) using a newly formulated polymer-enhanced suspension concentrate (SC-PE) of deltamethrin. The objectives of this study were to evaluate the efficacy of ORS using deltamethrin SC-PE and its effect on wild Aedes populations and to assess its residual bio-efficacy on painted cement walls against the pyrethroid-susceptible strains of laboratory-reared Aedes mosquitoes. Three rounds of spraying in a four-month cycle were conducted between 2014 and 2015 in four residential areas (low-rise and high-rise housing types) in Hulu Langat, Selangor. The bio-efficacy of the insecticide was evaluated by assessing its impact on vector population using ovitrap surveillance. Standard WHO wall deposit bioassay was adapted to determine bio-efficacy of deltamethrin, i.e. post 30 min knockdown and post 24 h mortality after exposure. During the treatment period, we observed significant reductions in the population of Ae. albopictus in the sprayed low-rise housing in both semi-indoor and outdoor environments, while in the high-rise housing, there was also a significant decline in Ae. aegypti population in the semi-indoor environment. The evaluation of the residual bio-efficacy of deltamethrin SC-PE against laboratory-reared Aedes mosquitoes showed that the insecticide lasted longer in the high-rise housing compared to the low-rise housing with >80% mortality achieved continuously for 16 weeks. We provide initial evidence on residual efficacy of deltamethrin SC-PE in reducing Aedes population size in the low-rise and high-rise housing. Our results showed that ORS is a promising tool in the dengue vector control and like IRS in malaria control; it is a powerful and effective method if conducted correctly. However, large scale and well-designed studies with entomological and epidemiological endpoints are still warranted before its routine use in dengue control.

Abstract: Poverty is not something new issue for a country. Poverty is seen as a problem that could negatively impact on a country. Malaysia also cannot escape from this poverty problem. Malaysia is a country where the Moslem people are majority and they are permanent resident. Therefore, from the perspective of Islam, poverty had been seen as a social disease [1]. According to the post’ or scholars’ statement, one of the ways poverty can be overcome is the implementation of the community development program. One of the community development programs in Malaysia that for farmer and house hold that involve in agriculture is called AZAM Tani. A study was conducted on participants AZAM Tani (Agricultural AZAM) areas of Seberang Perai, Penang. AZAM are words in Malay language. It is also short form and stand for End Time of The Poor. The method used was census. A total of 54 respondents were found. The results showed that the AZAM Tani program is able to help increase knowledge. Then with the knowledge that the participants had, they are able to raise their level of skills. This can be seen in the results of Spearman correlation indicating the relevance of knowledge to the implementation of the program and the relevance of relationship knowledge and skills with r = 0.612, p < 0.05. This relationship is positive. The study also shows an increase in the income level of the respondents.
Comparing the Accuracy of Network Utilization Performance between Real Network and Simulation Model for Local Area Network (LAN)  [PDF]
Mohd Nazri ISMAIL, Abdullah Mohd ZIN
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2008, DOI: 10.4236/ijcns.2008.14042
Abstract: This article presents a novel approach for the measurement and estimation of network traffic utilization between network nodes in heterogeneous environment. This research investigates performance evaluation of network interface on heterogeneous services and technologies environment. This study proposes an enhanced equation to evaluate the performance of network interface via Little Law and Queuing theories to improve the evaluation algorithm. To get accuracy results on the performance of simulation model, it measures (verify and validate) data from Local Area Network (real network environment). This project uses network management tool to capture those data and Fluke Optiview device to generate traffic. As a result, this simulation model can provide a good approximation of the real traffic observed in the real network environment. Through laboratory and field experiments, the result shows that the model via simulation is capable of approximating the performance of network utilization and traffic over heterogeneous services and techniques within a minimum error range.
Improved NCTF Control Method for a Two-Mass Rotary Positioning Systems  [PDF]
Mohd Fitri Mohd Yakub, B. A. Aminudin
Intelligent Control and Automation (ICA) , 2011, DOI: 10.4236/ica.2011.24040
Abstract: This paper describes an improvement of the existing nominal characteristic trajectory following (NCTF) as a practical control method for a two-mass rotary point-to-point (PTP) positioning systems. Generally, the NCTF controller consists of a nominal characteristic trajectory (NCT) and a PI compensator. A notch filter is added as a part of the compensator to eliminate the vibration due to the mechanical resonance of the plant. The objective of the NCTF controller is to make the object motion follow the NCT and end at its origin. The NCTF controller is designed based on a simple open-loop experiment of the object. The parameters identification and an exact model of the plant are not necessary for controller design. The performance response of improved NCTF controller is evaluated and discussed based on results of simulation. The effect of the design parameters on the robustness of the NCTF controller to inertia and friction variations is evaluated and compared with conventional PID controller. The results show that the improved NCTF controller has a better positioning performance and is much more robust than the PID controller.

Azizallah Roudini, Mohd. Hassan Mohd. Osman
iBusiness (IB) , 2012, DOI: 10.4236/ib.2012.42015
Abstract: More than two decades, international entrepreneurship (IE) has come out as a distinct academic discipline, and that concentrates on firms that become international from inception or near after it. However, comparatively little is known about the international entrepreneurship (IE), its capability and what drives the international performance of these firms with early and rapidly internationalizations. Therefore, the objective of the investigation is to reveal the dimensions of international entrepreneurial capability (IEC) and its effect on international performance (IP) in born global firms. The study will give an instruction to the born global (BG) managers, vision and strategy to the policymakers, and introduce the effectiveness role of international entrepreneurship capability (IEC) on international performance.
Poly(Acrylamide-Co-Acrylic Acid)-Zinc Acetate Polymer Electrolytes: Studies Based on Structural and Morphology and Electrical Spectroscopy  [PDF]
Mohd Faiz Hassan, Siti Zulaikha Mohd Yusof
Microscopy Research (MR) , 2014, DOI: 10.4236/mr.2014.22005
Abstract:

Solid polymer electrolytes (SPEs) of polyacrylamide-co-acrylic acid (PAA) as the polymer host and zinc acetate (ZnA) as an ionic dopant were prepared using a single solvent by the solution casting technique. The amorphous and crystalline structures of film were investigated by X-ray diffraction (XRD). The surface morphology of samples was examined by scanning electron microscopy (SEM). The composition and complex formation of films were characterized by Fourier transform infrared (FTIR) spectroscopy. The conductivity of the PAA-ZnA films was determined by electrochemical impedance spectroscopy. According to the XRD and FTIR analyses, all electrolyte films were in amorphous state and the existence of interaction between Zn2+ cations and the PAA structure confirms that the film was successfully prepared. The SEM observations reveal that the electrolyte films appeared to be rough and flat with irregularly shaped surfaces. The highest ionic conductivity (σ) of 1.82 × 10-5 Scm-1 was achieved at room temperature (303 K) for the sample containing 10 wt % ZnA.

Nurul Rabitah Daud, Mohd Fadzil Mohd Akhir
Open Journal of Marine Science (OJMS) , 2015, DOI: 10.4236/ojms.2015.53026
Abstract: This paper explores the dynamic of meteorological forcing on current circulation pattern in the vicinity of Bidong using an unstructured flexible mesh hydrodynamic model. The forcings were wind, tides, temperature and salinity. The seasonal wind monsoon, mixed tides with dominant diurnal and tropical monsoon climate is characteristics of Bidong Island. We find that this area has different current circulation patterns in response to monsoon changes. It also experienced a small scale of island wake during NE monsoon. This island wake was generated by a strong northeasterly wind. We performed a series of numerical simulations based on three dominant factors in circulation, and evaluated the model using wind, tides and density. We investigated the wind-driven circulation and residual current. This study contributes to the debates on hydrodynamic of current circulation in vicinity of Bidong Island. Specifically, this study was conducted to understand the changes of currents by seasonal wind (NE monsoon and SW monsoon), temperature and salinity.
Estimation the Density of Localized State Glassy Se100–xZnx Thin Films by Using Space Charge Limited Conduction Measurement  [PDF]
Mohd. Nasir, M. Zulfequar
New Journal of Glass and Ceramics (NJGC) , 2012, DOI: 10.4236/njgc.2012.22013
Abstract: The dc conductivity in vacuum evaporated amorphous thin films of the glassy alloys Se100–xZnx(2 ≤ x ≤ 20) are meas-ured in the temperature range (308 - 388 K). The dc conductivity (σdc) is increases with increased of Zn concentration in the glassy alloys. The activation energy (ΔE) decreases with increase of Zn content. The conduction is explained on the basis of localized state in the mobility gap. To study the effect of electric field, a Current-Voltage characteristic has been measured at various fixed temperatures. The Current-Voltage data are fitted into the theory of space charge limited conduction in case of uniform distribution of traps in mobility gap at high electric fields (E ~104 V/cm) of these materials. The density of localized state (g0) are estimated by fitting in theory of space charge limited conduction (SCLC) at the temperature range of (352 - 372 K) in the glassy Se100–xZnx. The density of localized state (0) near the Fermi level are increases with increase of Zn concentration in the (Se100–xZnx) thin films and explain on the basis of increase of the Zn-Se bond.

Mohd. Nasir, M. Zulfequar
Open Journal of Inorganic Non-metallic Materials (OJINM) , 2012, DOI: 10.4236/ojinm.2012.22002
Abstract: The DC conductivity and dielectric properties of glassy Se100–xZnx 2 ≤ x ≤ 20 alloys have been investigated in the temperature range 303 - 487 K with frequency range 100 Hz – 1 MHz. It is observed that DC conductivity decreases and the activation energy increases with Zn content in Se-Zn system. Dielectric dispersion is observed when Zn incorporated in Se-Zn glassy system. The results are explained on the basis of DC conduction mechanism and dipolar-type dielectric dispersion.
