Abstract: The results of a magnetic study of the Naraguta area, North central Nigeria are presented here. Regional-residual separation was carried out using Least Square method. The resultant regional map revealed a regional trending in a NW-SE direction. The magnetic residual values range from -487.828 n T to +405.447 nT. Short to moderately long dislocations were found in the residual magnetic map. Several magnetic closures of various sizes were also noticed. While the dicontinuities indicate the presence of minor to moderately long geologic, fault in the area, the closures depict the type and size of the anomalies that lie beneath the area. Magnetic lineaments trending in a NE-SW direction has been identified to pass through the study area. This concentration of magnetic lineaments may be connected with the occurrence of younger granites in the study area since almost all known younger granite complexes lie within the region dominated by this trends. Also a prominent ENE-WSW anomaly low has been identified in the Jos-Bukuru complex. The trend of the anomaly is believed to be roughly parallel to that of the main structural feature of the Benue trough indicating the probability that the Benue trough and the younger granite intrusive are related considering the stress, which initiated the formation of these features. 2-D spectral analysis of the magnetic anomalies over the area has been carried out in an effort to estimate the depth to magnetic sources. The result shows that the deeper sources have an average depth of 2.03 km while the shallower sources have an average depth of 265m.

Keywords: 131I, dose rate, radiation measurement, radionuclide
Abstract: In this paper, I- (adsorbed dose rate constant ) for 131I is calculated theoretically and is also determined experimentally applying important correction factors. These correction factors include those factors that affect the calculations, from the radioactive source to the sensor volume detector. Particular absorbed dose rate constants were calculated for each discrete line in the photon spectrum of 131I radionuclide with a yield per decay event >0.01% and the energy > 80 keV. Estimation of dose rate for radiation source may be required for planning radiation protection measures, calibrations of radiation instruments or for estimating the adsorbed dose to patients receiving brachytherapy.

Abstract: This paper proposes a digital fuzzifier with 7 bit resolution. To achieve a high performance, the A/D conversion and fuzzification operation are done simultaneously on the same functional block, through a programmable membership function. To implement the idea we have used flash method for the 4 LSBs which results in high speed conversion. Although the 4 bit converting is adequate for most practical appliations, we take advantage from successive approximation technique to achieve better precision, if needed. The proposed converter allows a significant amount of silicon area to be saved compared to fully parallel A/D. Result of extracting of the 7 bit A/D converter shows that the size of converter ' s layout is less than 0.02 mm2 in 0.35 ?m CMOS standard technology. Moreover, the Hspice simulation showed that it can achieve 25 MHz speed and total power dissipation is 5mw in the aforementioned technology.

Keywords: Pinus kesiya, Himalaya, North-east regions, Meghalaya
Abstract: Pines are the most economical groups of species found in the Himalayas. They provide valuable natural resources which contribute significantly to the local and industrial economy of the country and also protect the watersheds which sustains and regulates the water supply for the need of million that inhabit Himalayan river basins. Among various valuable natural resources of conifers, khasi pine has an important role in the north-eastern region of India. It is very propular with the people of Meghalaya and in reality; the people of the area use every part of the tree. The needles are used for stuffing mattresses, chair cushions, and cheap pillows and even as cementing fibre in the mud plastered wall. The needle litter in the forest is collected, burnt and used as soil correctives in potato beds. The branches and small wood are used as firewood. The knot and the core of the dead branches are collected and used in the destructive distillation for resin. The resinous wood is used as touch wood. The timber is used for house construction and good quality furniture. The increasing demand for various products, thus, necessitates immediate measures to enhance productivity of khasi pine so that deamnd could be met without compromising the environmental stability of the north-east. In this region, khasi pine forests provide for not only timber and fuel to the local populations but also support demand for packing wood, stakes vegetable cultivation and its needles are used as bedding in cattle sheds.

Abstract: The effect of water stress induced by application of polyethylene glycol 6000 during seed germination and seedling growth of Oroxylum indicum (L) Vent. was analyzed in present paper. The various osmotic potentials generated (-3, -5, -7.5 and -10 bars) showed significant decrease in germination percentage. At the osmotic potential of -7.5 and -10 bars, no germination take place. All the seedling growth parameters also showed inhibition with increase in osmotic potential.

Abstract: Germinability of seeds of Cedrus deodara Roxb. G. Don was studied under different conditions in the laboratory. Seeds were stored at four different temperature namely, room temperature (T1), 5 +10C (T2), 50+10C (T3),- 5 +10C (T4) and in three different container viz; poly bag (C1), canvas bag (C2) and plastic container (C3). Observation on germination parameters were observed at bimonthly for storage duration of ten month. The results revealed that the temperature -5 +10C (T4) performed better with highest mean value for all germination parameters ie.germination (71.18%), Germinative capacity (79.40%), Germinative energy (46.33%) and Germination value (11.36%) after ten months of storage. It was also observed that plastic container (C3) performed better with highest mean value for all germination parameters i.e. germination (67.63%), Germinative capacity (76.92%), Germinative energy (43.65%) and Germination value ( 10.45%) after ten months of storage.

Abstract: The present study was carried out to highlight physio-chemical properties of soils of mangrove forests viz., mangrove scrub, mangrove forest, salt water mixed forest and palm swamp in Sundarbans, West Bengal, India. The altitude of sampling sites was 6m to 7m above msl. The physio-chemical properties of the soils varied wtih species composition and altitude. Most of the samples weresilt-loam in texture. The highest particle density and bulk density was observed in salt-water-mixed forest where as the maximum water holding capacity and high volume expansion were observed in mangrove forest. The highest porosity was recorded in palm swamp forest. The pH values of the mangroves varied from 7.8 to 8.3 and EC ranged from 1.26 to 2.84 mS/cm2. The high percent of organic carbon was found in palm swamp forest. The maximum amount of available P and K was in salt water- mixed forest where as that of available N was in mangrove forest.

Abstract: A total of 250 random oligonucleotide primers were surveyed to identify sex of Simarouba glauca a tree born oilseed crop. Primer OPA-08900 was found to produce a consistent marker, which differentiated female from both male and andromonoecious sex plants. An identified random amplified amplified polymorphic DNA (RAPD) marker, OPA-08, linked to male sex in Simarouba was cloned and sequenced. Their end sequences were used to design an allele -specific sequence characterized amplicon region (SCAR) primer SCAR (12 f/r), which was found promising in male and andromonoecious sex. The marker designed was amplifed at a specific site of 915 bp only in male and andromonoeciuos plants. Theis would help to identify the sex of tree born oilseed crop Simarouba.
