The use of bivalves as bio-indicators in the assessment of marine pollution along a coastal area

The assessment of environmental pollution of the coastal areas of the Malaysian Peninsula was done by analyzing the contents of the heavy and trace elements in the bivalves blood clams (Anadara granosa) and green mussels (Perna viridis) and sediments at twenty-two sampling stations to look for prevailing trends. Heavy and trace elements analyzed in this study were As, Cd, Cr, Cu, Pb, Se and Zn. Two techniques, namely the neutron activation analysis (NAA) and atomic absorption spectrophotometry (AAS) were used in the quantitative determination of the heavy metals while Marine Sediment Reference Material (BCSS) and Lobster Hepatopancreas (TORT-1) provided the certified reference materials in the quality assurance control. The potential use of these bivalves as suitable bio-indicators was evaluated from correlation tests based on the concentrations of heavy and trace elements in the sediment-metals system to those in the bivalves

Wireless real-time haze monitoring device

Typically, the information received by public is based on 24-hour PSI from pollutant PM10 The 24-hour PSI reading often cause some confusion as most of the time. It does not correlate visually with the environment as seen with naked eye. Inaccurate reading may bring serious effect to people with respiratory problem. Furthermore, the reading from pollutant PM10 is not accurate as it measures particle matter as small as 10 micrometer in diameter, while the harmful particle matter is smaller than that. This project proposes a real-time portable wireless haze monitoring device, based on pollutant PM2.5 to measure air quality and beaglebone blackcontroller to control the transmission process of measured data taken via wireless data network to the MySQL database. The reading, which is real-time reading and more accurate compared to pollutant PM10, can provide haze awareness and guidance to people to plan their activities.Keywords: PSI; PM10; PM2.5; beaglebone black

Tapered plastic optical fiber sensor for dengue non-structural protein 1 (Ns1) detection

A simple fiber optic sensor is proposed and demonstrated for detection of different concentration of dengue non-structural protein 1 (NS1) using a tapered plastic optical fiber (POF). The working mechanism of the device is based on intensity modulation technique where the transmitted light intensity variation is measured when the probe is immersed into dengue NS1 antigen and antibody solution with various concentrations. The dengue NS1 antigen and antibody of various concentrations (1x10-2, 1x10-3, 1x10-4, 1x10-5, 1x10-6, 1x10-7, 1x10-8 mg/mL) were prepared by serial dilution of a stock concentration of 1mg/ml with phosphate buffer saline solution. The tapered POF is fabricated through a chemical etching method by using acetone and deionized water to achieve a waist diameter and length of 0.45 mm and 25 mm, respectively. For detection of dengue NS1 antigen, as the solution concentration varies from 1x10-8 mg/mL to 1x10-2 mg/mL, the output voltage of the sensor reduces linearly from 1.21 mV to 1.17 mV with a slope sensitivity of 0.004 mV/ (mg/mL) and a linearity of 92.61%. As for detection of dengue NS1 antibody, the tapered POF based sensor produces a sensitivity of 0.84 mV/ (mg/mL) with a linearity of 98.61%

Contextual Factors Influencing Health Information Systems Implementation in Public Sector : Investigating the Explanatory Power of Critical Success Factors

In this paper, we approach the field of critical success factors (CSF) by analyzing a successful case of IT implementation within the public health sector. The purpose of the paper is to gain further understanding of if and how well CSFs can explain a successful case. The main conclusion drawn is that even though the studied organization shows signs of common CSFs, this alone cannot explain the success. An important contribution from this study is thus the focus on contextual factors when trying to understand what makes an implementation project successful
