Forest policy in Orissa, as a matter of fact In India, has a long, ancestry, Sporadic attempts on the part of the native and British rulers to protect and exploit the forests form the ingredients of the present forest policy. Under the impact of planning forest policy exhibit new dimeonsions. Growth, stability Environmental and recreational aspects of forests and wild life protection, etc, form different Important facets of the new forest policy, Some gaps, however, have been identified in the structure of the forest policy pursued in Orissa It has been felt that the forest policy has not been looked at in depth as developmental imperatives warrant.

The potential usefulness of cationic polyelectrolytes in treating river water used for drinking purposes was investigated with particular focus on the removal of turbidity. A series of experiments were carried out using four commercial polyelectrolytes such as Magnafloc, Richfloc, 950C and 950 Cap. The efficacy of the process was first examined with demineralised water of known artificially produced turbidity. The optimum pH, concentration of reagents in clarification and the conditions affecting the interaction between the reagents and the turbid particles in water were investigated. Rapid coagulation removing some heavy metal ions and colour, was obtained by the use of fine magnetite particles as carriers. The reagent 950C was found to be superior compared to other reagents. It was possible to reduce the turbidity of the river water from 236 NTU to 3.6 at 5.0 mg/L of reagent concentration in conjunction with Al2(SO4)3 and magnetite particles in a period of five minutes.Keywords

Gravity-Magnetic mapping and resistivity sounding have been conducted in a grid pattern of 50 m × 100 m and 200 m × 200 m respectively over one square km area between Tokapal and Duganpal villages on Jagdalpur-Gidam road about 18-20 km from Jagdaipur township. The objective has been to map the eastern and the northern extension of an already known kimberlite sill in the area which is exposed in a pit and intersected in some drill holes at shallow depth to the west of the area surveyed.The Bouguer anomaly (BA) map reveals a near circular peak marginal high of + 0.5 mGal around 0/N100 station over the background value of -59 mGaI in the area surrounded by an envelope of +0.3 mGal, almost in a N-S disposition between the traverses W350 and E100 stretching from the northern end down to S400 grid. Another such N-S feature, somewhat subdued (+0.3m Gal), is recorded in the BA map, in the northeastern part of the area bounded by traverses E200 and E400 and the base line. It is interesting to note that this sill like body is exposed around station E200/S300 where no BA high is detected. However, in the magnetic (VF) map, this sill body is picked up as a dipolar anomaly. Joining the axes of the dipolar lows and highs, the magnetic kimberlite body is yet again resolved into two near circular bodies as recorded in the gravity map. A gap in the continuity of the kimberlite sill around E200 is also indicated.
3D Euler's deconvolution solutions arrived from both the gravity and the magnetic (VF) data assuming a sill type body have been extremely useful in demarcating the geometry of the causative body at three different depth levels.The resistivity in a grid pattern shows the evidence of buried kimberlite in the area characterized by a marginal resistivity high (30-130 0hm.m). A 3D subsurface map of the kimberlite sill using ROCK WORKS has been prepared from the resistivity data.
Several 2-D G-sMe ctions have also been presented constraining these from the results of resistivity survey. Such sections will immensely help in targetting future drill holes in the area. The 3D Euler's deconvolution solutions and the 3-D configuration of the Kimberlite body have lent the third dimension in prospecting the covered kimberlites through geophysical mapping.

Clostridium difficile with its virulence factors A and B toxins cause Pseudomembranous colitis. Bacterium was isolated from 57 dog and 41 pig diarrheic faecalsamples in cycloserinecefaxitin fructose agar media and molecular detection was done by amplification of gluD gene (755 bp). Variability of toxin genes in positive isolates was tested by multiplex PCR. Detection ofbinary toxin genes (cdtA and cdtB) was also done. Results showed 33.67% positivity with 18 and 15 fromdog and pig respectively, from which 10 and 5 were toxigenic and 11 pig isolates exhibited binary toxin. PCR-RFLP demonstrated toxinotype 0 in all A+B+ isolates.Keywords
