Watershed development programmes are aimed to mitigate the adverse effect of drought on crops and livestock, controlling desertification, encouraging restoration of ecological balance and promoting economic development of village community. Being a people oriented programme, it requires people's participation at various levels. Participatory approach is indeed a dynamic group process in which all members of a group contribute to the attainment of common objectives, share benefits accruing from group activities, exchange information and experience of common interest, and follow the rules, regulations and other decisions made by the group. Need for people's participation is articulated in terms of efficiency and/or costeffectiveness, equity in distribution of benefits, sustainability and empowerment of the people. In recent years watershed management has become the focal point of agricultural and rural development in rainfed areas of India and there has been increasing decentralization of responsibilities for management of natural resources to the community level. Role of people's participation and community organization in management of watersheds are discussed in this paper.- Potential of Bamboo in Vegetative Embankment

The Brahmaputra basin in India, particularly its valley in Assam, represents an acutely flood-prone region and occurrence of flood has been an age-old phenomenon in the riverine areas. During the rainy season, the rivers not only become filled up with water, but the excess amount of water also spill over their banks flooding their neighbouring regions. At the same time bank erosion occurs in almost all the large rivers destroying human habitats and their crop fields. The greatest single casualty due to recurrent floods, accounting for as much as 75 per cent of the total flood loss is the agricultural sector which happens to be the mainstay of the economy. Accelerated erosion due to deforestation and increased pressure on land due to explosion of population is a major cause of this increase in sediment yield. Biological means of protection against erosion are the cheap and simple practical solution that must be technically suitable for different conditions, economically viable with respect to the cost of both initial establishment/maintenance, ecofriendly, people-oriented and sustainable. Vegetative embankment models based on Bamboo and other species endemic to the northeast region can be a cost effective and sustainable solution to the alarming problem of soil stabilization and river bank erosion. The paper presents the various a!tpects of bank erosion in BrahmaputraValley and suggests vegetative controls for talking the problem.- Rb-Sr Whole Rock Age for Chait Series of Northwestern Himalaya

isotopic date on 12 samples of the Paliam and Darba granites of the Bastar Craton in Central India have defined an isochron age of 2308 ± 48 Ma. with initial Sr-isolopic ratio of 0.7354 ± 0.0097. Mineral ages on perthite, biolile and muscovite from tin- and rare metal-minearlised as well as non-minearlised pegmatites of the Bastar-Koraput Pegmatite belt within this craton have indicated two important dates of about 2050 and 1620 Ma. These dates are interpreted as (a) emplacement of the granite around 2300 Ma., (b) derivation of the pegmatites from this parent granite around 2050 Ma and (c) reselling of Rb-Srsystem at about 1620 Ma., concomitant with the metamorphic/uplift event in the nearby Eastern Ghats. The very high initial 87Sr/86Sr ratio of 0.735 for granite indicates thai they are crustal derived, possibly from a metasedimentary source.Keywords

Precambrian Central Gneissic Complex (CGC) in the Kameng district of Arunachal Pradesh comprises the oldest Sela Group thrusting over the Bomdila Group, with the Salari Group being the youngest. Augen gneiss of the Bomdila Group, granite of the Salari Group and hornblende granite gneiss of the Sela Group define Rb-Sr isochron ages of 1914 ± 23, 1536 ± 60 and 481 ± 23 Ma, respectively. The 481 Ma age on the hornblende gneiss from the oldest Sela Group is attributed to the resetting of Rb-Sr clock due to tectonic imprint of the Main Central Thrust (MCT). The 1914 Ma age of the augen gneiss, the oldest reported so far from the Arunachal Himalaya, is either the emplacement age or latest metamorphic event. The 1536 Ma old emplacement age of the granite intruding the black shale of the Salari Group disproves the hitherto considered Gondwana age for the black shale, and, thus, necessitates revision in its chronostratigraphy. (87Sr/86Sr)i of the hornblende granite gneiss and Salari granite is high (0.719 and 0.709) indicating a crustal source for these, whereas it is low for the augen gneiss (0.703) suggesting an inherited signature of the upper mantle source together with some crustal contamination. Rb-Sr whole-rock isochron ages from the Arunachal Himalaya are correlatable with those reported from other parts of the Indian Himalaya. These cumulatively point to at least three major periods of activity in the Himalaya at ca. 2060 ± 250, 1530 ± 90 and 530 ± 75 Ma.Keywords

Rb-Sr, Sm-Nd and Pb-Pb systematics on mafic granulites, intermediate-charnockites, charnockites, calcgranulites, orthogneisses, leptynites, granites and two (2) mineral samples (microcline and muscovite) from pegmatite have been studied Sm-Nd model ages (TDM) for most of the rocks cluster around 2 1 Ga Calc-Granulites gave Rb-Sr whole rock isochron age of 1339 ± 110 Ma with initial 87sr/86sr ratio(I R ) = 0 709 Mesoproterozoic age for the Metasedimentary. Group of rocks (calc-granulites) has been inferred based on their 87sr/86sr ratio also. Granites and leptynites have yielded Rb-Sr whole rock isochron ages of 823 ± 38 Ma, with I R = 0 713 and 894 ± 82 Ma, with I R = 0 708 respectively which are younger than the calc-Granulites. Microcline and muscovite from pegmatite gave Rb-Sr model ages as 532 and 491 Ma respectively. Granites, leptynites and calc-Granulites are derived from the crustal source as indicated by their high initial 87sr/86sr ratios. Most probably the protolith of the granitic and granulitic rocks is of Palaeoproterozoic age in this part of the Madurai Block. The minimum age of granulite grade of metamorphism has been inferred at c 850 Ma, indirectly on the basis of Rb-Sr ages of leptynites, which normally form during the evolution of granulite facies assemblages. Both granulite facies metamorphism and granitic magmatism probably took place during Neoproterozoic period correlatable to the early phase of Pan-African orogeny. Later decompression, causing mineral scale resetting of the Rb-Sr and Sm-Nd systematics, around 450-550 Ma, may correspond to the final exhumation, which brought the middle to lower crustal granulites to upper crustal levels, during the last phase of Pan-African activity. As per ages obtained on various lithounits in the present study the Metasedimentary Group of rocks (Mesoproterozoic) are younger than the Charnockite Group of rocks (Palaeoproterozoic) followed by the rocks belonging to the Migmatite Complex (Neoproterozoic).Keywords

The Precambrian Godhra Granite occurring in parts of central Gujarat, intrudes the metasediments of Lunavada and Champaner Groups. RbSr isochron based on 14 whole rock samples of the Godhra Granite gives an age of 965±40 Ma, with an initial 87Sr/87Sr ratio of 0.7109±0.0015. Geochemical data indicate its origin by partial melting of crustal rocks in post-orogenic environment.Keywords

Internet is the main tool for e-business. E-transaction is made faster by Internet. With the increase of e-transaction internet fraud or e-business fraud is increasing. Credit fraud in the banking sector is a growing concern. Few sort of card (debit/credit) fraud is decreasing by providing detection and prevention system from banks and government. But card-not-present fraud losses are increasing at higher rate because of online transaction as there is no chance to use Chip and PIN as well as card is not used face-to-face. Card-not-present fraud losses are growing in an un-protective and un-detective way. This paper seeks to investigate the current debate regarding the fraud in the banking sector and vulnerabilities in online banking and to study some possible remedial actions to detect and prevent credit fraud. The research also reveals lots of channels of fraud in online banking which are increasing day by day. These kinds of fraud are the main barriers for the e-business in the banking sector. This paper devised a new approach for fraud detection in these sector with help of graph database&by matching pattern of previous frauds.Keywords

The Dargawan gabbros intrusive into the Moli Subgroup of Bijawar Group, yielded Rb-Sr whole rock isochron age of 1967 ± 140 Ma. Based on the oldest age from overlying Lower Vindhyan (1.6Ga) and the underlying youngest basement ages (2.2 Ga), the time range of Bijawar sedimentation may be assigned as 2.1-1.6 Ga (Paleoproterozoic). Sm-Nd Model ages (TDM), obtained, for Dargawan gabbros, is c. 2876 - 3145 Ma. High initial 87Sr/ 86Sr ratio of 0.70451 (higher than the contemporary mantle) and negative εNdi (at 1.9 Ga) value of -1.5 to -4.5, indicate assimilation of Archaean lower crustal component by the enriched mantle source magma at the time of gabbroic intrusion. The dolerite, from Damdama area, which is intrusive into the basement and overlying sediments of Chandrapur Group in the central Indian craton, yielded Rb-Sr internal isochron age of 1641 ± 120 Ma. The high initial 87Sr/86Sr ratio of 0.7098 and εNdi value of -3.5 to -3.7 (at 1.6 Ga) is due to contamination of the mantle source magma with the overlying sediments. These dolerites have younger Sm-Nd Model ages (TDM) than Dargawan gabbros as c. 2462 - 2675 Ma, which is similar to the age of the Sambalpur granite, from which probably sediments to this part of Chattisgarh basin are derived. Hence mixing of sediments with the Damdama dyke during its emplacement, gives rise to high initial 87Sr/86Sr and low initial 143Nd/144 ratios for these dykes. The c. 1600 Ma age indicates minimum age of onset of the sedimentation in the Chandrapur Group of Chattisgarh basin. Both the above mafic intrusions might have taken place in an intracratonic rift related (anorogenic) tectonic setting. This study is the first reliable age report on the onset of sedimentation in the Chandrapur Group. The total minimum time span of Chandrapur and Raipur Group may be 1.6 Ga to 1.0 Ga (Mesoproterozoic). The unconformably underlying Shingora Group of rocks of Chhattisgarh Supergroup thus indicates Paleoproterozoic age (older than 1.6 Ga). Most part of the recently classified Chattisgarh Supergroup and Bijawar- Vindhyan sequence are of Mesoproterozoic-Paleoproterozoic age and not of Neoproterozoic-Mesoproterozoic age as considered earlier. Petrographic study of basic dykes from Damdama area (eastern margin of Chattisgarh Supergroup) indicated presence of primary uranium mineral brannerite associated with goethite. This is the evidence of mafic intrusive providing geotherm and helping in scavenging the uranium from the surrounding and later alterations causing remobilisation and reconcentration of pre-existing uranium in host rocks as well as in mafic dyke itself otherwise mafic rocks are poor source of uranium and can not have primary uranium minerals initially. It can be concluded that mafic dykes have role in uranium mineralisation although indirectly.Keywords
