Modification of soil structure of sand tailings: I. preliminary study on the effect of organic amendment and iron on soil aggregation

The effectiveness of dried palm oil mill effluent (decanter cake), which contains 14% organic carbon, and iron solution in promoting aggregation in sand tailing soil was determined. The addition of iron (JT decanter cake at rates of 20 and 60 t h«l had no significant effect on the aggregation and stability of the sand. At a higher rate of 100 t h«l, decanter cake gave a significant effect on aggregate stability. With the addition of 0.1 % Fe, the rate of decanter cake application for effective stabilization was reduced to almost half. However, generally the extent of aggregatian was law (% aggregation>2mm was only 5.6%). This could be due to the low amount of very fine sand and silt amounting to only 5.8%, and the absence of clay in the sand tailings. It is postulated that an improvement in the soil structure of sandy tailings using amendments essentially requires the presence of fine soil fractions viz. clay and silt and/or very fine sand in sufficient amounts. Their presence will kad to better soil structure Jonnation in the sand tailings by the amendments and hence to better water and nutrient economy of the soil

Identifying Predictors of Academic Success for Part-Time Students at Polytechnic Institutes in Malaysia

A central challenge for higher education today is to understand the diversity and complexity of nontraditional students’ life experiences and how these factors influence their academic success. To better understand these issues, this study explored the role of demographic characteristics and employment variables in predicting the academic success of part-time students at four polytechnic institutes in Malaysia. Demographic characteristics studied included respondent’s age, gender, marital status, number of children, parent’s educational level, and financial resources. Employment variables assessed were number of years working, job relatedness to the program, job satisfaction, and monthly salary. A total of 614 part-time students completed the survey. Results indicated that being an older student, being female, paying for their own education, and having high job satisfaction were statistically significant predictors of part-time students’ academic success. Understanding the effects of demographic characteristics and employment variables on students’ academic success might help administrators and educators to develop teaching and learning processes, support services, and policies to enhance part-time students’ academic success

Computational fluid dynamics modelling of the air movement in an environmental test chamber with a respiring manikin

In recent years, computational fluid dynamics (CFD) has been widely used as a method of simulating airflow and addressing indoor environment problems. The complexity of airflows within the indoor environment would make experimental investigation difficult to undertake and also imposes significant challenges on turbulence modelling for flow prediction. This research examines through CFD visualization how air is distributed within a room. Measurements of air temperature and air velocity have been performed at a number of points in an environmental test chamber with a human occupant. To complement the experimental results, CFD simulations were carried out and the results enabled detailed analysis and visualization of spatial distribution of airflow patterns and the effect of different parameters to be predicted. The results demonstrate the complexity of modelling human exhalation within a ventilated enclosure and shed some light into how to achieve more realistic predictions of the airflow within an occupied enclosure

A Mixed Model Study on Perception Towards Outcome Based Education from Graduating Scholars in a Private University

Outcome-Based Education (OBE) is now identified as essential to excellence in education. OBE can be described as the transparent application of a set of measurable criteria in setting a standard of proficiency. The students’ perception is the most crucial part as they are the medium of the system, as they are the ones who undergo the system thoroughly, and are the final product of the OBE system. Thus, their perception will directly show the effectiveness of the OBE system. This study focused on students’ perception on OBE system that had been applied in KPJ Healthcare University College (KPJUC) since 2014, in terms of students’ understanding and academic achievement. This is a mixed model study, which consisted of quantitative and qualitative study. A descriptive method of analysis was used, wherein the quantitative data were gathered using questionnaires and a survey interview was done as a qualitative supplementary data. The findings of this study discovered that the students have a positive perception toward the system

The Effect Of Trade Specialization And Institutional Quality On Intra-Asean Trade

Intra-ASEAN trade is stagnant at 20% to 25% for the past few decades. This is partly because ASEAN members are overl-reliant on non-ASEAN countries for their exports. Several suggestions have been put forward such as exchange rates and trade agreement which observed so far as having limited effect to increase intra-ASEAN trade. In this study, we propose and examine the role of trade specialization and the quality of institutions among ASEAN for a period between 1996 and 2015. ASEAN countries are generally endowed with similar resources have a tendency to compete with each other for similar products
