Dynamical behavior of coumarin compounds in alcohol solvents
It is observed that, the rotational motion of probe molecule in methanol solvent increases as the temperature increase. We also investigated that, C30 rotates faster than C7 in the same solvent. It is all due to the friction between solute and solvent, diffusion and hydrogen bonding establish between alcoholic group and coumarin molecule. We have also determined the excited state and ground state dipole moments in alcoholic series solvents by using Bakhshiev, Chamma-viallet equations and Quantum mechanical treatment. From the results, it is found that, excited state dipole moment is greater than the ground state dipole moment, which indicates that excited state is more polar than the ground state

98-104 Species of Gracilaria Greville were collected from Japan, India and Malaysia. Growth rate experiments were conducted at different temperatures, salinities and light intensities. Gracilaria vermiculophylla was found to be the fastest growing species with a growth rate of 22.32%. The growth rates of all species varied with salinities, but most of them attained their optimum growth rates at a normal seawater salinity 35‰. During the temperature tolerance experiments, it was observed that only G. vermiculophylla had a high temperature tolerance limit of up to 35°C. The temperate and the tropical species of Gracilaria were divided into three groups depending upon their optimum growth rates at the optimum temperatures. Group I consisting of G. arcuata and G. textorii from Japan with optimum growth rates at 20°C. Group II consisting of G. vermiculophylla, G. incurvata from Japan and G. foliifera, G. corticata from India with optimum growth rates at 25°C, while group III consisting of G. edulis from India and G. lichenoides from Malaysia with optimum growth rates at 30°C. </smarttagtype
Hermatypic corals of the Goa Coast, west coast of India
480-481Three species of reef building corals: Porites (Porites) lutea, Favites pentagona and Turbinaria mesenterina were recorded near Grandi Island, off Marmugao (Goa, India). The coral patch was observed at a depth of 3 m. This is the first report of hermatypic corals along the Goa Coast. A non-reef building solitary coral of the Atlantic region Astrangia sp. was also recorded and could have been introduced in Indian waters due to maritime activities
Outcome of open cholecystectomy and laparoscopic cholecystectomy- A comparative study
Background: Cholelithiasis, which continues to be one of the most common digestive disorders encountered, was traditionally being dealt by conventional or open cholecystectomy. With the introduction of laparoscopic cholecystectomy, the surgical community witnessed a revolution in basic ideology and the importance of minimal access surgery has suddenly impacted. Materials and Methods: 50 patients admitted at Adichunchanagiri institute of medical science with a diagnosis of calculous cholecystitis underwent open / laparoscopic cholecystectomy. 25patients constituted each group. Results: The duration of Laparoscopic cholecystectomy was significantly more than for open cholecystectomy (median 95 min in LC and 80 min in OC). One patients of laparoscopic group required conversion to open procedure. The drains were required in less number of patients of Laparoscopic cholecystectomy group and for less number of days. No Wound infection was seen in Laparoscopic cholecystectomy patient when compared to 5 in OC patients. The Visual Analogue Scale for pain in the post op period was significantly less for LC patients compared to OC patients (median 7 in OC group as compared to 4 in LC group) . The duration of hospital stay was significantly longer for OC group than for LC group (Mean of 7.84 days versus 3.68 days respectively). The cosmetic result was significantly better in LC group than OC group ( Mean cosmetic score of 4.72 in LC group and 3.44 in OC group. Median score was 5 for LC group and 3 for OC group). Conclusion: Laparoscopic cholecystectomy is Superior to Open cholecystectomy. Therefore, laparoscopic cholecystectomy is considered the “Gold Standard” procedure for cholecystectomy
Identification of Geological and Geomorphological Landforms in Thanjavur District Using Remote Sensing & GIS
Abstract — In this Paper Abstract has been researched to study of Identification of Geological & Geomorphological landforms in Thanjavur District using Remote Sensing & GIS Techniques. The Cauvery Delta is located in Thanjavur District. It is one of the important rice bowl of Tamilnadu. The total area of Thanjavur District is about 3396.57 Sq.km. The eastern part of Thanjavur is connected with Bay of Bengal. This study is carried out by using IRSP6 LISS IV Satellite image and Toposheet 1:50000 Scale. From this, the thematic maps (Geomorphology, Geology, and Drainage) are created. The Geomorphological features like Flood Plain, Alluvial plain, Deltaic plain and Eolian plain were studied.Similarly the Geological features like Fluvio marine, alluvial-fluvial, sripermuputhur / Sivaganga formation, Nasal formations were analysed.In the same way, the drainage pattern of Thanjavur district is found and the pattern was Dichotomic Using ARC GIS. Keywords- IRS P6 LISS IV, ARC GI
