The influential of physico-chemical parameters on the distributions of oligochateas (Limnodrilus sp.) at the polluted downstream of the tropical Langat River, Peninsular Malaysia

The influential physico-chemical parameters on the spatial and temporal distribution of oligochateas (Limnodrilus sp.) at the polluted downstream of Langat River were studied in comparison to the unpolluted upstream for 10-months sampling from March 1998 to February 1999. Based on the correlation analysis (CA) and multiple stepwise regression analysis (SRA), the distribution, abundance and density of Limnodrilus sp. were almost consistent during the ten time samplings from April 1998 to February 1999. Based on CA, the density and distribution of Limnodrilus sp. correlated negatively with the pH and dissolved oxygen (DO) while positively correlated with conductivity, biological oxygen demand (BOD), NO3, NH3, total suspended solids (TSS), chemical oxygen demand (COD) and dissolved concentrations of Cu and Zn. Based on SRA, most of the above parameters are selected as influential factors in affecting the distribution and presence of Limnodrilus sp. on the tropical river. This indicated that the Limnodrilus sp. is a pollutant resistant worm since they can survive in the poor water quality ecosystem. These results based on CA and SRA signified the resistance and tolerance of Limnodrilus sp. survived at the polluted ecosystem of the tropical river. Hence, Limnodrilus sp. is a good bioindicator of polluted rivers in the tropical ecoregion. Journal of Applied Sciences and Environmental Management Vol. 10(3) 2006: 135-14

Inhibition ability of cocoa pod extract on tyrosinase activity

Cocoa pod is a waste from cocoa industry. About 75 percentage weight of cocoa fruit is pod. The pods have variety of colors which resemble the various active compounds with potential health benefits. Normally, the cocoa pods were utilized as fertilizers, source of potash and activated carbon. However, the application of cocoa pods as cosmeceutical ingredients has not been extensively explored and documented. The objective of this study was to investigate the effects of cocoa pod extract on tyrosinase activity where good suppression of tyrosinase activity may indicate its potential to be used as skin whitening agent. In tyrosinase assay, the effects of cocoa pod extract on the activity of tyrosinase from mushroom to oxidize L-DOPA substrate were measured. Results showed the cocoa pod extract had better performance of tyrosinase reduction activity at almost two-folds compared with kojic acid and ascorbic acid. Hence, cocoa pod extract has the potential to be used as skin whitening active ingredients

Stability of blended palm oils during potato frying

The aim of this study was to determine hydrolytic stability [acid value (AV)] and oxidative stability [peroxide value (PV) and conjugated dienes (CD)] of selected blended oils during potato frying. The blended oils were prepared by blending palm oil with corn oil (POCO), sesame oil (POSO) and rice bran oil (PORBO). Blended vegetable oils were prepared in a ratio of 1 to 1 (v/v) and tested for 0, 10 and 20 times after frying potato. AV and PV were determined by titration method, while CD was determined using the spectrophotometric method. Increasing frequency of oil frying contributed to increased level of AV in all blended oils. PVs were increased in all samples, with most noticeable increment observed in POSO, followed by PORBO and POCO. CD levels of the blended oils were also increased after 20 times of potato frying compared with the unused oil and after 10 times of frying. POCO was the most stable oil in terms of hydrolytic and oxidative stabilities. It is most suitable for deep-fat frying of potato chips and industrial application

Outdoor mobility assistive technologies for people with vision impairment or blindness – a state of the art

World Health Organization (WHO) estimated that about 1.3 billion people live with a level of vision impairment. Outdoor mobility represented a big challenge for people with vision impairment or blindness (VIB). Developing assistive technologies (ATs)to facilitate the mobility of people with VIB represents a vital solution since the last two decades. Researchers investigate in detecting and avoiding static and dynamic obstacles in the indoor and outdoor environments. However, many of the proposed systems have not been addressing user requirements. The purpose of this paper is to stimulate researchers for more work to overcome the challenges of outdoor mobility of people with VIB. The study selected academic research from the most recently proposed mobility ATs. Then, it classified them technically, based on the used technology to; camera, sensors and combination of camera and sensors. Next, it presented the general features and weaknesses of each technology. Finally, it illustrated the strengths and drawbacks of each AT, depending on the technical factors and the users’ acceptance from the authors’ points of view. Consequently, this work explains the reasons behind the rare use of the current ATs

Industrially produced trans fatty acids: major potential sources in Malaysian diet

This study was conducted to determine the major potential sources of industrially produced trans fatty acids (IP-TFAs) in Malaysian diet. Levels of IP-TFAs were initially determined in samples (n = 136) collected from 8 food groups (baked products, snacks, dairy products, breakfast cereals, fast foods, semisolid fats and cooking oils, and fried foods). A survey was carried out to 105 subjects aged 19-59 years old to determine the intake of IP-TFAs using Food Frequency Questionnaire (FFQ). The IP-TFAs range from 0-5.79% of food, with the highest found in semisolid fats and cooking oils (0.1-5.79%), followed by fast foods (0.04-0.86%), baked products (0.01-0.29%), breakfast cereals (0.06-0.45%), snacks (0.03-0.26%), dairy products (0-0.26%), and fried foods (0.002-0.06%). A Spearman’s Rho rank test showed that there were significant correlations (p < 0.05) between 4 of the food groups (semisolid fats and cooking oils, fast foods, fried foods, and baked products), with the total IP-TFA intakes of subjects. In general, total IP-TFAs intakes of subjects were < 1% of subjects’ diet (0.067%-0.91% of subjects’ total calorie intakes). This indicate that high fat foods (semisolid fats and cooking oils, fast foods, fried foods, and baked products) were the main contributor of IP-TFAs in Malaysian diet, despite the low proportion oftransfatty acids, following their high frequency of daily intake

Characterization of microcrystalline cellulose isolated through mechanochemical method

Mechanochemical process, which involves simultaneous ultrasound and alkali treatment, has been used to isolatemicrocrystalline cellulose (MCC) from raw oil palm empty fruit bunch (REFB) fibre. Three steps have been used to preparethe MCC, namely removal of lignin, removal of hemicellulose and finally production of MCC. The crystallinity index inMCC is found to be 81% which is 54% higher than that of REFB and 45% higher than that of cellulose. Besidescrystallinity, the crystal size (28.03Å) of MCC is also enhanced noticeably by 53% as compared to the REFB and 28% ascompared to cellulose. The degradation temperature, and the residue content reveal the excellent thermal stability of MCCextracted through this mechanochemical technique
