Abstract: Boudh is one of the centrally located backward district of Orissa. Because of its location in the Eastern Ghat, the tropical dry deciduous flora is very heterogeneous and diverse. Kandha and Kolha are the primitive tribes attributing for 12.47% to total populaiton of the district. They use 44 numbers of wild plant species belonging to 30 family and 36 genera for curing different diseases and disorders. Out of these, euphorbiaceae and fabaceae are the most exploited families. However, further pytochemical, pharmacological and clinical investigation is essential for scientific validation of these ethno drugs which may help in discovering new drugs for mankind.

Abstract: Intraformational conglomeratic horizon within the Upper Bhuban unit of Bhuban Formation, Surma Group (Lower to Middel Miocene) exposed to two localities in the vicinity of Aizawl, Mizoram has yielded fish ramins mostly in the form of isolated teeth, dental plates and spines. Majority o these belong to diverse selachians and have already been described. We describe here dental plates and a caudal spine belonging to two species of Myliobatis, one of Aeteobatus (batoids) and four of Diodon (teleosts) from the same fossil localities. These fish remains together with associated selahians and mega-invertebrates suggest the existence of a tropical to subtropical climate and a warm shallow marine set-up near to the shoreline in a high-energy environment during the deposition of the fossiliferous horizon.

Abstract: The Nagaon district in Assam is in a sub-humid region with a greater part of the district comprising alluvial soil ranging from pure sand on the banks of the Brahmaputra to stiff clay The area is subjected to frequent flooding by rivers durign a spell of 4 months in a year. In the present study, flood hazard layer is considered as the primary input and is integrated with land use/land cover, infrastructure and population data and weightages are assigned to each class. based on this, village flood risk index map for Nagaon district has been generated. The results of analyses indicate that about 167 villages are in the moderate-high risk index zone. About 35,354 ha of the district is in high flood hazard zone and about 25,281 ha of crop area is affected annually. We conclude that use of multi-temporal satellite datasets, coupled that use of multi-tempora satelilte datasets, coupled with GIS tools, are useful in idnetifying vulnerability of infrastructure, population and land use in the even of flood disaster and in calculating the flood risk index.

Abstract: We porpose a hybrid missing data imputation technique using positive selection and correlation-based feature selection for insurance data. The hybrid is used to help supervised learning methods improve their classification accuracy and resilience n the presence of increasing missing data. The positive selection algorithm searches for potential candidates for impuation and the correlation-based feature selection method searches for attributes have a significant effect on the target outcome. The imputation is performed only on those attributes that have an impact on the target outcome. The results show that the classification accuracy and resilience of supervised learning methods improve significantly when applied with the imputation strategy under these assumptions.

Keywords: Pressure swing adsorption (PSA)
Abstract: A three-be seven-step pressure swing adsorption (PSA) helium purification system has been developed exploiting PSA. It removes impurities like N2 and O2 from a ternary mixture leaving out high-purity helium from the gas mixture. In the present experimental set-up a feed gas stream containing helium (55.0 mol%), nitrogen (~35.0 mol%) and oxygen (~10.0 mol%) has been introduced into the system with predetermined pressure and flow rate. Lithium exchanged low silica X-zeolite (LiLSX) molecular sieve with an average pore diameter of 0.9-1.0 nm has been used as the adsorbing medium. Total cycle time of the PSA system was conveniently chosen to be 180 sec. The PSA system is operating successfully resulting in high-purity helium (>99.9%) with a yield of around 89%.

Keywords: Cedrus forest, Numerical analysis, phytogeography, Taurus mountain range
Abstract: Cedrus libani forests have been under the anthropogenic pressure for thousands of years. The unattainable topography of the Taurus mountain range (Southern Anatolia) has prevented cedar in this region from being extirpated, in contrast to its other distribution areas in Syria and Lebanon. Numerical analyses of releves confirmed the individuality of associations, as well as the division of C. libani forests into two ecological and floristicaly different groups/alliances (Abieti-Cedrion and Lonicero-Cedrion). Abieti-Cedrion is distributed in the middle and eastern Taurus whereas Lonicero-Cedrion appears in the Western Taurus. The main gradients of C.libani forests were detected. It was noticed that the distribution and floristic composition of C. libani forests is strongly affected by the geographical factors. Topographical factors are also influential on their distribution. C. libani forests are fundamental components of the Mediterranean phytogeographical region and floral elements, but under more continental conditions, where the influence of the Mediterranean climate decreased, the porportion of Iran-Turanian and Euro-Siberian floral elements increase, especially towards the east and north, as well at higher altitudes and on steeper sites.

Abstract: We installed seaweed reef for restoration of barron ground coast. We hollowed out a U-shaped groove in a cross-shaped artificial seaweed reef and covere it with a zinc sheet (U-bar) to transplant Ecklonia cava growing on Dellenia wood by hand, installing the U-bar on the artificial seaweed reef, fixing it with concrete. Thus seawee can be attached easily, with pre-installe stainless bolts and nuts. The length of Ecklonia cava leaf transplanted to the cross-shaped reef was 7.2 cm in February 2005 reached its maximum size, 35.9 cm (n=30) by July. Thereafter, it decreased to 18.9 cm in October due to shedding. The leaf weight after the experiment was 24.8 from the initial 0.4 cm (n=30). Regression anaysis showed Y=0.7875X-4.6488 (R2 = 0.7225) for blade length and Y=0.0025X2.6733 (R2 =0.8711) for leaf weight. The high values of the R2 values for the two measurements were highly reliable, with the reliability of the linear regression function higher than that of the functions of 2 variables. The artificial seaweed forest constructed in the barren ground was highly comparable with natural seaweed forest in terms of growth, indicatign that the artificial seaweed construction can be done in an easy, efficient and economically viable way. This further indicates that the construction can be done in a easy, efficient and economically viable way. This furhter indicates that the technology developed by the present study can be extensively used for the project for artificial seaweed forest construction.

Keywords: Trace elements, Sediment pollution, Lake
Abstract: During the period 2008-2009, eight sampling stations were carried out on Lake Uluabat to assess trace element distribution in the lake sediments and to idnetify major sources of the sediment pollution. Ten elements, including Iron (Fe), Manganese (Mn), Zinc (Zn), Chromium (Cr), Nickel (Ni), Copper (Cu), Lead (Pb), Cadmium (Cd), Arsenic (As), Boron (B) were detetmined in the sampled lake sediments. The lowest and highest variation intervals ( 5.0377 - 27664.197 mg kg -1) were found for Cd and Fe, respectively. Concentrations of Cr (131.627 mg kg-1), Ni (220.032 mg kg-1) and Cd (5.0377 mg kg-1) in sediment samples were higher than in the other regions. Moreover, suspended slids, conductivity, pH temperature and the organic matter %were found to affect the concnetrations of sediment.on the basis of the findings of the study, it was concluded that higher concentrations of trace elements in dry seasons increase in suspended matter, pH, percentage organic content, and conductivity.

Abstract: This study focused on the photocatalytic destruction of dichloromethane (DCM) in indoor air using the nano TiO2/LDPE composite film as an economical photocatalyst. The nano-TiO2 was dispersed in a polyethylene matrix to form composite film. The photocatalytic activity of the nano-TiO2/LDPE composite films was evaluated through the degradation of dichloromethane (DCM) under UV-irradiance at specific wavelength of 254 nm. The percentage of nano-TiO2 contents varied from 0.5, and 10% (wt cat/wt LDPE composite film). The results derived from the kinetic model revealed that the photocatalytic rates of 5 and 10 wt % nano-TiO2/LDPE composite films follow the first order reaction while the rate of the film without TiO2 followed the zero order reaction. At low concentration of DCM, the rate of photocatalytic degradation of the DCM was slower than that at high DCM concentration. The 10 wt % of TiO2 contnet of the nano-TiO2/LDPE composite film yielded the highest degradation efficiency fo 78%, followed by the removal efficiency of 55% for the 5 wt % of TiO2 content of the nano-TiO2/LDPE composite film. In contrast with the composite film containing nano-TiO2, the LDPE film without adding nano-TiO2 expressed the degradation efficiency fo 28%.

Abstract: Phytoplankton assemblages and species succession along Lake Burullus (Southern Mediterranean) is expressed as carbon biomass (mg cm-3) using a standard spreadsheet based on the species cell volume cell-1 carbon relationship. High Chl a levels were measured (maximum 85-126 mg m-3) reflecting a dense phytoplankton population ( up to 8.3 x 103 cell ml-1 and 5.5 x 103 mg cm-3) throughout the lake body with maximum concentrations at the western sector of the lake (S1). A diverse phytoplankton community was determined. Cell count data revealed the dominance of a mixed phytoplankton taxa, however biomass data indicates over-dominance of Bacillariophyceae (up to 98%). Good correlation (r=0.73, p<0.05) was found between Chl a and carbon biomass with various cell carbon/Chl a ratio according to variations in community structure. Bacillariophyceae were the most dominant, particularly at the middle (S2) and the western parts (S1) during periods of high nutrient (silicate) and good weather conditions (during spring/summer months). Chlorophyceae were abundant with Scenedesmus sp. mostly dominant, particularly at P-rich sites. Dinoflagellates peaked only during calm and high light summer months (May -July) being at a maximum level at S1. Euglenophyceae were less contributed to total phytoplankton abundance and peaked only; as a transition stage; at S1 during January and March (winter months). Cyanophyceae were numeroius along with maximum peak at S2 affected by the southern drains. Excessive nutrient enrichment into the lake alters the existent structure of phytoplankton community. The water quality index indicated a poor water quality status of the alke This may led to increase the possibility of toxic algal blooms to invade the lake ecosytem and, in turn, affect the lake fish yield.

Abstract: ASAM with Rumex crispus extract organosolv pulping was developed by using 1.5-dihydroxy-3-methoxy-7-methyl-anthraquinone from Rumex crispus root, instead of anthrquinone. ASAM was also produced as a control pulping. Both pulps were made by handsheets from fast growing P.deltoides clone (Samsunp. clone), Robinia pseudoacacia L. and Pinus pinaster grown in Turkey for wood fibrous raw materials. The mechanical consisting tensile, bursting and tear values and optical values of ASAM handsheets yellowness, brightness and whiteness were compared to ASAM with Rumex crispus L. extracted. It is concluded that ASAM with Rumex crispus extract pulping suits well in the manufacturing of special papers.

Abstract: Five species of Azospirilium isolated from Manakkudi mangrove ecosystem were subjected for their efficiency to find out their growth parameters potential for the successful establishment of mangrove seedlings. Of the isolated five Azospirillium species, Azospirillum species, Azospirillum lipoferum (60%) was found to be the dominant one. But the level of maximum indole acetic acid (IAA) production (19.8 mg. ml-1) and nitrogen fixation (5.9 C2 H2hr-1) was identified with A. brasilense. Further, A . brasilense showed significant (p<0.05) level of increased growth parameters [maximum root length (29.55%), averag root length (7.39%), total Chl (55.36%), carrotenoids (28.57%), Chl B (37. 50%), carbohydrates (90.91%) and total amino acids (78.95%)] in Avicennia officinals when compared with control group. Further, A. brasilense also showed significant (p<0.05) level of increased growth parameters [average number of primary roots (40%), average biomass (44.44%), average shoot biomass (55.56%), total Chl (20%), Chl b (77.78%) and carotenoid (1.54%)] in C. decandras seedlings when compared with control group. Similarly, the average number of primary roots (23.08%), average root biomass (15.52%), average shoot biomass (15.30%), carbohydrate (20%) and total amino acids (44.44%) were found significant (p<0.05) in A. irakense inoculated R. apiculata seedlings. In conclusion, Azospirillum brasilense was found better for the growth of Avicennia officinalis and Ceriops decandra seedlings, but Azospirillium irakense was found better for Rhizophora apiculata seedlings.

Abstract: Aquaculture industry depends on development and testing of protocols for rearing and breeding of new aquaculture species as these techniques vary with species. In the present study attempts have been made to study the effect of temperature and salinity on the rate of growth of the marine ornamental fish, Pomacentrus caeruleus under artificial conditions. Results reveal the length and weight of the fish to increase gradually at an average rate 0.10 cm and 0.23 g with decreasing salinity (25 ppt to 5 ppt) at 250C and 6.54 condition factor (K). Statistical output indicates a significan positive relationship between K at 250C and K at 300C (R=0.557, P<0.05). Correlation indicated growth rate to be higher between 250C and 300C. This is in contrast to the hypothesis which sttes the weight of the fish to be different at different temperatures, F (2,54) = 5.713, P<0.05. Tukey ' s test results indicate a signifiant difference in the weight of the fishes acclimatized at different temperatures. Mortality rate was highest in 200C followed by 300C while leas in 250C. The incidence of diseases was highest in 200C and the acclimatization period highest in 300C. In conclusion it appears that Pomacentrus caeruleus exhibits allometric growth at lower salinities and at a controlled temperature of 250 C.
