Addition of digested sewage sludge at concentrations of 2% and 10% (v/v) to the water increased coughing rate in big head and tilapia (Ps significantly decreased (Psludge concentrations of 6% and 2% (v/v)respectively. Copper (Cu), cadmium (Cd) and zinc (Zn) are trace metals which are commonly found in sludge. Cu caused a significant increase (Ps of 0.3 and 0.2 μg/ml respectively. Zn caused significant increase (Pml. Neither fish responded to Cd of up to 2μg/ml in the water. However, when the levels of these trace metals in the digested sludge were measured, they were below that which can cause significant changes in the respiratory movements. Therefore, the changes in ventilation and coughing rates after addition of sludge may be due to the presence of substances other than these metals. The results of this experiment provides a guideline to control the level of sludge that can be used in rearing these fresh water fish in ponds

A new method for estimating the center of Iumen from colonoscopic images using edge segments is developed, The RGB color imaged of colon is initially converted into Hue,saturation, and Intensity components. Edge detecion is then performed on the intensity component to extract strong intensity gradients, which correspond to the rings of muscle inside componeat to extract strong intensith gradients, which correspond to the rings of muscle inside the colon, spurious edges as well as edges resulting from specular reflection from the colon wall are removed by verifying the saturation value distribution in the vacinity of the edges. Edge segments

Adenosine and its corresponding nucleotides adenosine 5′-monophosphate (AmP), adenosine 5′-diphosphate (ADP) and adenosine 5′-triphosphate (ATP) are important biomolecules that provide energy and substrates for various cellular biochemical processes[1]. There have been strong demands for sensitive and reliable analysis of these nucleotides because the determination of their levels in cells may provide valuable information for understanding cellular energy metabolism. Analysis of adenosine nucleotides is a big challenge because these chemicals exist together with high cellular background in samples. moreover, nucleotides are extremely polar due to the presence of multiple phosphate groups that may interfere with chemical determination. In particular, the nucleotide phosphates are not retained under conventional reversed-phase chromatographic conditions because of their extremely high polarity[2]. The most common approach for quantitative analysis of nucleotide phosphates in cellular extracts is to determine indirectly the corresponding parent nucleosides resulted from enzymatic dephosphorylation after the nucleotides were separated by using an anion-exchange solid phase extraction. The generated nucleosides were analyzed by using liquid chromatography with ultra violet absorption detection (LC/UV), radio-immunoassay and liquid chromatography-mass spectrometry-mass spectrometry (LC-ms-ms)[3-6]. Because nucleotides are not retained under conventional reversed-phase conditions, ion-suppression high performance liquid chromatography (HPLC)[7], capillary electrophoresis[8] and ion-pairing HPLC[9-11] have been employed to circumvent the poor retention problem. The high selectivity of ms and ms/ms techniques provides great separation and detection power, making them attractive alternatives for the trace analysis of nucleotides. The application of negative ion electrospray ionization (EsI)-ms to nucleotide analysis has been reviewed[12,13]. The use of negative ion EsI-ms see
