Animated Introductory Calculus： Development and perception

Recent years it has an explosive development of IT technologies. However, the problem of natural integration of modern technologies in teaching and learning mathematics is far from its final solution. In teaching mathematics at universities, these capabilities either are ignored or have extremely limited applications. In our study, we consider animation as one of the tools that could increase students＇ motivation, curiosity and understanding. In order to evaluate the perception about using animation in the study of calculus, a brief survey was conducted in University Utara Malaysia （UUM）. The survey consisted of 17 lecturers and 25 students from UUM. The survey also conducted in UPM （University Putra Malaysia） and UniKL （University Kuala Lumpur）, which comprised of 82 students and 49 students respectively. At the same time, we are interested in whether or not the perception of students differs by factors like gender, age group, entry qualification, program of study and previous grades. This survey was conducted in UPM comprised of 160 students. In this paper, we describe our data and report our findings, make a comparison between students＇ perception in UPM, UUM and UniKL. Further a comparison is also made regarding perception of UniKL students from two different programmes of study. To evaluate the performance of students, a simple comparative experiment between Computer Aided Learning Method （CALM） and the Traditional Learning Method （TLM） conducted in UUM and UPM and we report our preliminary findings in this paper.     

Validation of the short form of the career development inventory with an Iranian high school sample

A short 33-item form of the Career Development Inventory was validated on a sample of 310 Iranian high school students. Factor analysis indicated that attitude and cognitive subscale items loaded on their respective factors, and that internal reliability coefficients at all levels were satisfactory to good. Support for validity was demonstrated by associations in the expected direction for career decidedness and career decision-making self-efficacy. This short form of the inventory shows promise as a measure of career maturity with students from a non-Western country.     

Finite element analysis and modeling of water absorption by date pits during a soaking process

Date pits for feed preparation or oil extraction are soaked in water to soften before milling or extrusion. Knowledge of water absorption by the date pits helps in better managing the soaking duration. In this research, the process of water absorption by date pits was modeled and analyzed using Fick's second law of diffusion, finite element approach, and Peleg model. The moisture content of the pits reached to its saturation level of 41.5% (wet basis) after 10 d. The estimated coefficient of diffusion was 9.89×10-12 m2/s. The finite element model with a proposed ellipsoid geometry for a single date pit and the analytical model fitted better to the experimental data with R2 of 0.98. The former model slightly overestimated the moisture content of the pits during the initial stages of the soaking and the latter model generally underestimated this variable through the entire stages of soaking process.     

Psychosocial impact of mothers with perinatal loss and its contributing factors: an insight

Objective:To evaluate the psychosocial impact among mothers with perinatal loss and its contributing factors.Methods:A cross sectional study was conducted in University Kebangsaan Malaysia Medical Centre (UKMMC) from April 2008 to May 2009 using Edinburgh Postnatal Depression Scale (EPDS) and self administered questionnaire.Results:Sixty-two respondents were included and most of them were working mothers (77.4%).The mean age of the respondents was (31.0±5.6) years and a majority of the subjects aged between...     

Analysis on fused deposition modelling performance

Fused deposition modelling （FDM） is one of rapid prototyping （RP） technologies which uses an additive fabrication approach.Each commercially available FDM model has different types of process parameters for different applications.Some of the desired parts require excellent surface finish as well as good tolerance.The most common parameters requiring setup are the raster angle,tool path,slice thickness,build orientation,and deposition speed.The purpose of this paper is to discuss the process parameters of FDM Prodigy Plus （Stratasys,Inc.,Eden Prairie,MN,USA）.Various selected parameters were tested and the optimum condition was proposed.The quality of the parts produced was accessed in terms of dimensional accuracy and surface finish.The optimum parameters obtained were then applied in the fabrication of the master pattern prior to silicone rubber moulding （SRM）.These parameters would reduce the post processing time.The dimensional accuracy and surface roughness were analyzed using coordinate measuring machine （CMM） and surface roughness tester,respectively.Based on this study,the recommended parameters will improve the quality of the FDM parts produced in terms of dimensional accuracy and surface roughness for the application of SRM.     

Bread wheat varieties as influenced by different nitrogen levels

INTRODUCTION Dera Ismail Khan lies in Pakistan’s arid zone (71.07° longitude, 31.57° latitude and 500 m above sea level). This zone is in the extreme south of (NWFP) Pakistan at the bank of the River Indus. Dera Ismail Khan is bounded by Sulaiman Range to the West, the Indus River on the East, Marwat and Bhit- tani Ranges on the North and Vehowa Nala (Punjab) on the South. Besides certain local variability the area is comprised of four basic divisions viz mountains, a series …     

An integrated, multiparametric flow cytometry chip using ��microfluidic drifting�� based three-dimensional hydrodynamic focusing

In this work, we demonstrate an integrated, single-layer, miniature flow cytometry device that is capable of multi-parametric particle analysis. The device integrates both particle focusing and detection components on-chip, including a “microfluidic drifting” based three-dimensional (3D) hydrodynamic focusing component and a series of optical fibers integrated into the microfluidic architecture to facilitate on-chip detection. With this design, multiple optical signals (i.e., forward scatter, side scatter, and fluorescence) from individual particles can be simultaneously detected. Experimental results indicate that the performance of our flow cytometry chip is comparable to its bulky, expensive desktop counterpart. The integration of on-chip 3D particle focusing with on-chip multi-parametric optical detection in a single-layer, mass-producible microfluidic device presents a major step towards low-cost flow cytometry chips for point-of-care clinical diagnostics.

The English Translation of Arabic Puns in the Holy Quran

The pun is a tricky use of a word or phrase which has very different meanings that are closely interrelated, or of words with the same sound but different meanings. The Pun is a term with a dual meaning: “close” using obvious reference, and “far” using obscure reference. The hidden is usually meant. The close meaning is the sooner that comes to the listener’s mind. However, the speaker targets at the far one yet use the close to hide it. Translating the Quran text always raises several serious challenges in translation; these challenges are due to the different translations of puns and the misinterpretations between the intended meanings of a pun with their basic concepts, which could result in a certain amount of ambiguity. The study examines the Quranic corpus and its three versions of English translations. The study utilizes the typology of Delabastita?s for horizontal puns, Nida’s techniques of dynamic and formal equivalent and Newmark’s translation methods. This research attempts to investigate the semantic meaning of puns in the Quran translation and to define the translation techniques applied in translating the Quranic puns from Arabic into English.
