Studies were conducted on a two row semi-automatic vegetable transplanter to determine the optimum funnel side slope angle in the feeding and metering mechanism at different seedling ages and different types of seedlings. The optimum side slope of the funnel has been decided by laboratory experimentation so that not a single seedling sticks to the funnel side after being dropped from the finger tray of the feeding mechanism. The experiments have been designed as a three Factors Complete Randomized Design with four replications. It was found that, at funnel side slope angle of less than 75° with the horizontal, the per cent of seedlings slipped into the drop tube decreased as the length of seedlings increased. At side angle of funnel of 75° and more, 100 per cent seedlings were slipped into the drop tube irrespective of crop and size of seedlings. Behaviours of different crops were found to be different below 75°. The crop with less foliar development such as chilli slipped more easily than other crops having more foliar development such as brinjal. So a funnel side slope angle of 75° has been taken as optimum to ensure cent per cent slippage of seedling from side of the funnel to the dropping tube for all crops under study.Keywords

Statistical analysis of phenol concentration in groundwater of Durgapur, West Bengal, has indicated groundwater pollution by industrial effluents carrying phenolic compounds. A second degree multiple regression expression (with goodness fit of 76%) clearly shows decreasing concentration of phenol away from the potential sources. A smoothing technique called kriging to fit a 3D-scatterplot of phenol concentration by latitude and longitude has been applied to study the pattern of spatial variation of phenol concentration. Contour plot based on successive vertical slices through the surface of kriging, smoother overlaid on the data coded by phenol concentration, depicts high phenol concentration well beyond the WHO (World Health Organisation) specified potable water quality.Keywords

The long stretch of coastline on either side of the Indian peninsula is subjected to varied coastal processes and anthropogenic pressures, which makes the coast vulnerable to erosion. There is no systematic inventory of shoreline changes occurring along the entire Indian coast on 1 : 25,000 scale, which is required for planning measures to be taken up for protecting the coast at the national level. It is in this context that shoreline change mapping on 1 : 25,000 scale for the entire Indian coast based on multidate satellite data in GIS environment has been carried out for 1989-1991 and 2004-2006 time frame. The present communication discusses salient observations and results from the shoreline change inventory. The results show that 3829 km (45.5%) of the coast is under erosion, 3004 km (35.7%) is getting accreted, while 1581 km (18.8%) of the coast is more or less stable in nature. Highest percentage of shoreline under erosion is in the Nicobar Islands (88.7), while the percentage of accreting coastline is highest for Tamil Nadu (62.3) and Goa has the highest percentage of stable shoreline (52.4). The analysis shows that the Indian coast has lost a net area of about 73 sq. km during 1989-1991 and 2004-2006 time frame. In Tamil Nadu, a net area of about 25.45 sq. km has increased due to accretion, while along the Nicobar Islands about 93.95 sq. km is lost due to erosion. The inventory has been used to prepare a Shoreline Change Atlas of the Indian Coast.Keywords

Bleeding is one of the rare presentations of Amyloidosis. The mechanism behind spontaneous or peri- interventional bleeding in patients of amyloidosis is complex and involves multiple co-existing factors like coagulation factor deficiency, abnormal synthesis of coagulation factors due to advanced liver dysfunction, acquired Von Willebrand disease, platelet dysfunction, amyloid angiopathy and other unknown mechanisms. We present a case of middle aged female, presenting with spontaneous retroperitoneal haemorrhage, on further investigations was found to have systemic amyloidosis and secondary severe factor X deficiency (2.7 % of normal by one stage factor assay method). Factor X deficiency (both inherited and acquired) is known to present with the most severe bleeding phenotype. The management option for such acute spontaneous haemorrhage is limited and mostly supportive in nature. Definitive treatment is directed towards the primary pathology and requires chemotherapy and hematopoietic stem cell transplantation.Keywords
