Abstract Chemical oxygen demand (COD) and ammoniacal nitrogen were the problematic parameters in landfill leachate treatment. Combination of activated carbon and zeolite as filter medium may reduce this problem. This study was conducted to find treatment alternative by combining the low cost adsorbent such as limestone and rice husk carbon waste and ordinary adsorbent media, activated carbon and zeolite as a single media. All the adsorption media was crushed and sieved to a particle size of 150µm. The optimum ratio was predicted by mean of a batch equilibrium experiments. Ordinary Portland Cement (OPC) was used as a binder at 30 percent by weight. Activated carbon and rice husk carbon was grouped as a hydrophobic media where the optimum ratio was 1:1. Zeolite and limestone was in hydrophilic media group which the best ratio was 3:1. The ratio for hydrophilic and hydrophobic media had been chosen as 7:1 accordingly to adsorption behavior of ammoniacal nitrogen and organic constituents (COD) to the media. The optimum conditions for adsorption batch study were found at pH 7, 200rpm in shaking speed and 90 minutes of contact time. The results showed that the equilibrium data were fitted and favorable adsorption by both of the Langmuir and Freundlich isotherms while Langmuir isotherms was slightly better fitted for ammoniacal nitrogen and Freundlich was good for COD removal in term of regression coefficients (R 2 ). Langmuir adsorption capacities (Q) for ammonia and COD were 43.47mg/g and 256.41mg/g respectively while Freundlich (K F ) were 0.00135mg/g and 0.03891mg/g respectively

Research Article Status of Emotional Intelligence (EI) Level of Biomedical Science Programme in Kuala Lumpur

Abstract: Emotional Intelligence (EI) is part of those who regulate their emotions according to a logically consistent of emotional functioning. This cross-sectional study is carried out among year 1 to 3 students of Biomedical Science Programme in Kuala Lumpur The questionnaire is based on three criteria which are intrapersonal ability, stress management and general mood. The sample size is 135 students by using stratified random sampling. The general objective of this study is to determine the emotional intelligence level of Biomedical Science students among socio demographic factor. The results showed the mean of EI male students (111.84±12.92 S.D.) is lower than that in female students (112.02±10.23 S.D.), the mean of EI among student staying in campus (112.55±10.947 S.D.) are higher than cam us student staying off-campus (110.76±10.274 S.D.) and the mean of EI among first year (114.35±13.32 S.D.) is the highest compared to that in Year 2 (113.16±9.592 S.D.) and Year 3 (109.93±10.169 S.D.). However there was no significance mean difference of EI between gender, year of study and residences (p>0.05). In conclusion, Emotional Intelligence (EI) is at average level (79.7%) and it was not depending on gender year of study and residences
