Character recognition from a scanned document page involves difficult task due to the free-flow nature of handwritten. In this paper, a geometric feature extraction approach is implemented with efficient learning mechanism for training and testing neural network for Tamil handwritten script. After selective preprocessing steps for constrained inputs, the document is split into paragraph, and then segmented to line, word and individual character for further recognition. The geometric features for each character are trained in an Effective Learning Machine (ELM). With this information, each testing character is analysed for recognition. This procedure results more than 95% accuracy for individual characters. © Research India Publications.

Biosorption of. lead: (II) ions from aqueous solution utilizing natural adsorbents have been .investigated/Few ecofriendly precursors are derived from Sapindus Emarginata, Tamarindus-Indica and Aegle marmelos. The rinds collected from above plants are used to prepare micro adsorbents such as SERF", HRP, and AMRP. They are characterized by proximate and chemical analysis. The surface morphology of the green adsorbents was studied by SEM. These are subjected for the batch.work studies of divalent Lead from aqueous solution. The influence of various factors namely pH, contact time and adsorbent dosage.was studied.The optimal pH.value for Pb (IT) adsorption is 5.0 for all the adsorbents. The elimination of lead ' from industrial effluents also examined. It is observed from the study that all the adsorbents mentioned in this work can be used as low cost,adsorbents for the removal of Pb (H) from various industrial effluents. © Global Science.

Present study is focused on the impact of effluent from tanneries and textile industries on the chemical characteristics of various water bodies in and around Erode, Tamilnadu, India. More than 40 tanneries and 500 textile dyeing industries are there in Erode. The surface water bodies affected are River Cauvery, Kalingarayan canal and Lower Bhavani Project canal which are used for drinking, household and irrigation purposes. Sixteen water samples were collected from various parts of industrial region and the samples were analyzed. Standard procedures were adopted to calculate the physical properties and trace elements in water samples. It is found in many samples that the water quality gets deteriorated. Presence of heavy metal toxicity such as Chromium, Cadmium and Lead also identified in some stations. Hence the flow of industrial, municipal and household effluents into the surface water causes serious pollution problems. A Perspective of environmental pollution associated with various industrial effluents and its remedies are described. © Global Science Publications.
