Keywords: Carbonatite complex, kimberlite, olivine, shonkinite, ultrabasic rock
Abstract: The compositional variations of olivine from shonkinite (shon) and associated ultrabasic rock (ubr) are analysed and an attempt is made to trace their magmatic evolution. The analysed olivine in shon is subjected to a prolonged period of magmatic crystallization with the development of zoning of augite, aegirine-augite and jadeite at its peripheral portions by reaction with residual magma. On the other hand, the composition of olivine from ubr represents intermediate position in the course of magmatic evolution of olivine occurring in shon. The high concentration of Ca-Na-K-Al in olivine from ubr indicates its kimberlitic affinity. These features indicate that shon magma is the parent magma for ubr. The shon occurs in the form of nodules/xenoliths in ubr, which is a member of the ultrabasic complex in this area. Further study is required to isolate ubr of kimberlitic affinities from the ultrabasic complex enclosing the potash-rich alkali syenites at the inner portion of Jogipatti basin, which is a part of the Tiruppattur carbonatite complex, Tamil Nadu.

Keywords: Climate change, floods, soil nutrient loss, organic matter loss
Abstract: Climate change has resulted in several kinds of aberrations in the weather phenomenon all over the globe. The recent unprecedented rainfall leading to floods in 13 districts of North Karnataka was said to be one such event. Very high rainfall received over a short period of time in a region dominated by black soils, resulted in severe loss of crops, soils, soil organic matter and soil nutrients besides destruction of humans, livestock and farming infrastructure. The shallow depth and heavy texture of the soil made the situation worse. An estimate made after the calamity revealed that nearly 287 million tonnes (mt) ot top soil, 8 lakh tonnes of soil nutrients and 39 lakh tonnes of soil organic matter were washed away. In monetary terms, about 853 crores rupees worth of soil organic matter and 1625 crores rupees worth of plant nutrients, and nearly 57.5 mt of soil microbial biomass were lost from the region during this short period. In addition, nearly 2 lakh ha of cultivated fields in the flood-affected area were deposited with sand along the river courses. These losses have severe long-term implications on crop productivity and rural economy of the region. The present study points out the damages caused to the soil and other natual endowments of the area, and the amelioration measures needed to bring back the area to cultivation for the future.

Abstract: Three groups of mulberry plants of MR2 variety were bio-fertilized with Azospirillum, phosphobacteria and vermicompost respectively. Three groups of third instar larvae of Bombyx mori, a hybrid (L X NB4D2) between a multivoltine strain (Local, Tamil Nadu) and a bivoltine strain (NB4D2) were fed with leaves harvested from Azospirillum, phosphobacteria and vermicompost bio fertilized mulberry plants respectively. The control worms were fed with mulberry leaves harvested from mulberry plants which were manured with cow dung alone. When the cocoons were fully formed by the silk worms, reeling performances (filament length, filament weight, denier, renditta, sericin & fibroin content) were studied. The results revealed that the reeling performances increased gradually in the order, worms fed with Azospirillum bio fertilized mulberry leaves, phosphobacteria bio fertilized mulberry leaves, and vermicompost bio fertilized mulberry leaves. It was clear that vermicompost is the best bio fertilizer for mulberry plants.

Abstract: Culture conditions were standardized for initiation of callus cultures from Nothapodytes foetida using hypocotyl explants. Callus cultures were established on Murashige and Skoog ' s medium supplemented with different concentrations and combinations of auxins (NAA & 2,4-D) along with cytokinin (BAP). The camptothecin content was detected and identified using High Pressure Liquid Chromatography (HPLC). The medium fortified with 2-mg/l 2, 4-D and 0.3 mg/IBAP was synthesized maximum camptothecin content of 0.033 mg/g of callus from hypocotyl explants.

Abstract: Influence of light on spatial orientation and web construction of Cyrtophora citricola has been analysed. The webs are constructed in permanent basis and it takes 4-5 nights for completion with hubs 15 cm apart. The spider exhibits characteristic east west orientation using the direction of the plane of polarization of the light from the blue sky. Deviation of head and abdomen according to the light intensity that is the spatial orientation of the spider possibly helps in thermoregulation.

Keywords: Mulberry silkworm, Bombyx mori, Hybrids, Season
Abstract: The newly evolved single cross hybrids of mulberry silkworm viz., MH-1 x NB4D2, BL-24 x NB4D2 and BL-23 x NB4D2 were evaluated during rainy season under tropical climate by feeding with M-5 and B-1 mulberry leaves. All the new hybrids viz., MH-1 x NB4D2 (37.6 g/10 larvae), BL-24 x NB4D2 (36.1 g/10 larvae) and BL-23 x NB4D2 (35.3 g/10 larvae) have recorded significantly robust larval growth and higher silk yield (3.26 g, 3.38 g and 3.38 g/10 cocoon shells, respectively) as compared to 30.8 g/10 larvae of larval growth and 2.6 g/10 cocoon shells of silk yield in the existing commercial hybrid, Pure Mysore x NB4D2. Among new the hybrids, MH-1 x NB4D2 was found to be promising in majority of the traits viz., effective rate of rearing (82.7%), pupal weight (15.5 g/10 pupae), cocoon weight (18.8 g/10 cocoons), single cocoon filament length (991 m) and denier (2.97). V-1 mulberry leaves enhanced the silkworm growth (35.55 g/10 larvae), silk productivity (4.33 cg/day), effective rate of rearing (80.4%), pupal weight (14.7 g/10 pupae), cocoon weight (18.0 g/10 cocoons), silk yield (3.23 g/10 cocoon shells), cocoon shell ratio (17.9%), longer silk filament (964 m) and finer silk (3.0 denier) over M-5 mulberry.

Keywords: Bioremediation, DNA polymorphism, Industrial effluents, Bacillus cereus
Abstract: Industrial effluent (Textile dye house, tannery, distillery & paper mill) samples were collected from Trichirappalli and Karur Districts. Heavy metal content of the samples were analyzed to isolate and characterize total heterotrophic bacterial population from the effluents and to screen for bacterial strain Bacillus cereus BNEF 18, effective in resisting the 4.0 mM of ambient chromium heavy metal. The sterilized industrial wastes are kept in conical flask and added pure B. cereus strain. They are kept in under constant shaking for 5 days on a rotary shaker at a uniform speed of 150 rpm. After the specified period, the bacteria harvested by refrigerated centrifugation and stored physiological saline at 40C, until used for further analysis. Protein profiling by SDS-PAGE revealed the appearance of new polypeptide fractions in the bacterium exposed to dye house and paper mill effluents, probably indicating the induction of Metallothioneins or stress-induced proteins. DNA from B.ceresus was extracted and amplified using random primers, A 07, A 10 and A 11 (IDT, New Delhi). Amplified DNA samples were fractionated by agarose gel electrophoresis (1.7% agarose), viewed on a UV transilluminator and photographed using orange filter. The study underlines the need for genetic characterization of bacterial population with bioremediatory potential as an important parameter in deciding the strategy of pollution management.

Abstract: The present study is aimed to elucidate the effect of azadirachtin, a neem product on haematological changes of albino rat, Rattus norvegicus. The rats were treated with azadirachtin for 8, 16 and 24 days and after the completion of specific experimental period; the W.B.C., R.B.C counting and E.S.R. were significantly affected in both male and female rats i.e. progressive increase may be due to the hyperstimulation to erythropoeitic tissue due to stress of azadirachtin. The results reveal that the azadirachtin have been shown dose dependant increase in haemoglobin percentage and variations in the clotting and bleeding time of blood in both male and female rats.

Abstract: The Palayakayal mangrove wetlands of Thoothukudi coast are inundated by high saline water and sometimes by fresh water during the monsoon seasons and brackish water or sea water during other periods and this work provide a base for forecasting the seasonal fluctuations of physico-chemical parameters. The temperature of atmosphere, water and sediment is highly variable. The salinity, pH and dissolved oxygen of the study area are significant for the growth of mangroves. The high rainfall was recorded during North east monsoon (October to December). The wind action was higher in July and August and the direction of flow is from West to East.
