A Review on Potential Toxicity of Artificial Sweetners vs Safety of Stevia: A Natural Bio-Sweetner
Artificial sweeteners have increasingly become an area of controversy in the world of food and nutrition. Consumers are oftenly barraged with a number of contradictory opinions and reports regarding the safety and efficacy of sweeteners. Artificial sweetener consumption may cause migraines or headache, skin eruptions, muscle dysfunction, depression, weight gain, liver and kidney effects, multiple sclerosis and blurred vision. But on the other hand natural sweetners like stevia and its products are safe and don’t cause any health problem. So it’s important for the consumer to choose sweeteners with great care.

Teaching and learning mathematics and science in English in primary schools in the state of Johor, Malaysia
This article attempts to highlight the opinions of the public on the effectiveness of
the use of English in teaching and learning Mathematics and Science (PPSMI) in primary schools in Johor. After nearly six years of its implementation, some people found out that the students have not demonstrated a good command of the language and the acquisition of knowledge of Mathematics and Science is seen to be declining. The teachers also do not seem to adapt well in the implementation. A group of respondents from among the headmasters and headmistress have given their views through a questionnaire and structured interview that showed the government's intention to strengthen the English language in teaching and learning Mathematics and Science did not show an impressive result. Thus, the study suggests that the government can try to give an option of using both languages in the implementation of this policy
Training Teachers to Implement Evidence-Based Practices Specifically Designed for Students with Autism Spectrum Disorder
Special education teachers are usually subjected to in-service training on Evidence-Based Practices especially those who work with students Autism Spectrum Disorder (ASD). Increasing teacher’s capability of using EBPs identified by the National Professional Development Center (NPDC) on ASD has become the most prominent need to serve students with autism. The purpose of this study was to investigate to what extent teachers’ performance is related to EBPs when they after they start their career. A mixed methods research design used in this study to explore the most prevalent practices, the common type of training on these practices, and teachers' knowledge and perceptions of using these practices. The undergraduate preparation programs and modality of training and time consuming to achieve mastery level of implementation among teachers will be discussed. Ten teachers have participated in this study. Results indicated that most of the training programs left beginner teachers underprepared to implement EPBs for teaching students with autism.

Foreign investment, government expenditure, and economic growth in Malaysia
This study uses the ordinary least squares technique to examine the effect of foreign investment and government expenditure on the growth in GDP per capita in Malaysia over the period 1978-2005. The regression results showed that the growth of export and ratio of government expenditure to GDP are the driving forces in enhancing the economic growth in Malaysia. Foreign investment and previous year real income per capita growth depict positive impact, whereas population growth exerts a negative impact on economic growth
Dual-band microstrip loop antenna for wireless application
In recent years, microstrip and printed antennas are widely used in order to fulfill the commercial needs. The emergence of wireless applications requires compact antenna easy manufacture. The purpose of this project is to design of dual band microstrip loop antenna for wireless applications with a reduction in size. The aim of this antenna was to operate from 2 GHz to 4 GHz. A square microstrip patch antenna has been chosen as antenna design pattern due to its low-profile structure. The development of this project comprised two main stages where the first level is a software simulation (CST Microwave studio2012) and secondly is a hardware development. CST Microwave studio2012 has been used to simulate the antenna design for a purpose of preliminary design which the inherent of the advantages of the antenna can be identified, then the second stage is the development of the microstrip patch antenna which have been fabricated on FR4 substrate and tested using the network analyzer which has range between to 1GHz to 14GHz. Based on this project, the antenna parameters such as return loss, radiation pattern, voltage standing wave ratio (VSWR) and bandwidth have been investigated. For further investigation, a substrate material with higher dielectric constant can be used to reduce a microstrip antenna size. The dual band antenna performance shows agreement between both simulation and measurement results
Design and Fabricate Filament Winding Machine and Analysis of Cotton/Epoxy and Pandanus/Epoxy
This project concerned with filament wound cotton/epoxy and
pandanus/epoxy composite tubes. Monofilament winding machine has been
designed and fabricated. It is later used in fabricating the composite tubes. The
performance of this machine was measured. The results revealed that the winding
angle depended primarily on the carriage speed traversing at speed synchronised
with mandrel rotation. Also, the efficiency of the machine showed that winding at
high angles relative to rotational axis was very high (i.e. at 90° the efficiency is
100%). Winding at low angles (parallel to rotational axis) was difficult. The surface finish depended on the fibre tension, the wiping process and band formation 0. e.
smooth surface finish at 4.4 kN).
The behaviour of filament wound cotton/epoxy and pandanus/epoxy
composite tubes was studied experimentally. Circular cylindrical of cotton/epoxy
and pandanus/epoxy were loaded in uni-axial compression. The test results show
that cotton/epoxy hoop tubes the maximum strength was found to be 13kN and for
the 80° cotton/epoxy tubes was found to be 10.6kN. For the pandanus/epoxy hoop
tube the maximum strength was found to be 0.3kN. Flat specimens were also
prepared from wound tubes and loaded in uni-axial tension. The cotton/epoxy
composite tubes were tested under internal pressure. The results show that the
maximum pressure that the tube can be withstand was found to be 5 bar. Maximum
stress and maximum strain theories are used to predict the failure of these tubes.
Finite element method also used in the analysis of cotton/epoxy composite tubes.
The uni-axial tensile test results show that the mean modulus was found to be
3 867.6 MPa for the 80° laminated tensile test specimens and 1067.0 MPa for hoop
(90°) laminated tensile test specimens. The maximum strain mean in 80° and 90°
laminated tensile specimens are essentially the same (0.1). The urn-axial
compression test results show that in the condition of hoop (90°) laminated tubes
and 80° laminated tubes the load-displacement curve is linearly up to initial failure
A Powerful Optimization Approach for the Multi Channel Dissemination Networks
In the wireless environment, dissemination techniques may improve data access
for the users. In this paper, we show a description of dissemination
architecture that fits the overall telecommunication network. This architecture
is designed to provide efficient data access and power saving for the mobile
units. A concurrency control approach, MCD, is suggested for data consistency
and conflict checking. A performance study shows that the power consumption,
space overhead, and response time associated with MCD is far less than other
previous techniques.Comment: 9 Pages, IJCNC Journal 201

Applications of 18(F) FDG PET/CT in oncology
The escalating costs of conventional diagnostic technology in oncology have yet to obviate futile surgery intervention and the spiralling treatment cost. The evolution in engineering technology which looks at the correlation of the anatomy and the function of tumours i.e. Positron Emission Tomography-Computed Tomography (PET-CT) have impacted on the improved diagnostic accuracy and treatment in oncology. Clinical data have demonstrated that the information provided by PET/CT often changes patient management. This review addresses the value of PET-CT as a surrogate molecular marker in tumours and to discuss some issues in adopting PET/CT in routine daily practice as supported by the numbers of literature reviews of its application in oncology since it was first commercialized in 2001. The description of the technology used in multimodality imaging has gained encouraging interest among physicians, policy makers and insurance companies on the importance of the PET-CT, for which roles are not limited to the staging, disease prognostication and treatment monitoring with potential impact on treatment cost and justification of radiation safety for the patient. PET/CT is a useful tool in cancer investigation as evidenced by its role as a surrogate marker in underpinning the cellular reprogramming of different pathological entities
