Joint Forest Management (JFM) is eliciting peoples' participation in the management of natural forests for sustainable management. The Interface Forestry Programme implemented to reclothe degraded forests since 1988 is a precursor to the present JFM initiatives in Tamil Nadu. The advantages and constraints in using JFM approach are discussed. The synergetic effect of biological , hydrological and sociological approaches adopted in JFM strives to ameliorate the conditions of rural people and facilitate their co-operation in the management of adjacent degraded natural forests in an integrated manner. Such an approach promises not only rejuvenation of the natural forests but also improved quality of life of the people living adjacent to the forests.- A Review of Phytochemical Studies of Digitalis Species

A review of phytoconstituents and biological activities of Digitalis species has been presented. Despite the fact that there are about 24 species of this genus spread around the world, the present survey revealed that only 17 species have been studied phytochemically. Hence an attempt is made to present a review on the phytochemical studies of Digitalis species which would possibly serve as a source for much potent cardioactive molecules.Keywords

Artificial recharge of groundwater using treated wastewater continues to rise, especially in arid and semi-arid countries. Artificial recharge as a means to enhance the natural supply of groundwater aquifers is becoming increasingly important in groundwater management. The present pilot study aims to planning and designing of artificial recharge structures for an ideal housing complex using treated waste water generated within the complex. Basic operational water requirement is estimated to quantify the water to be recharged for a balanced and sustainable water recharge cycle. The study estimated the volume of generated waste water as well as rainfall runoff water from the ideal housing complex. The rate of natural ground water recharge, rainfall runoff and total treated effluent available for recharge is estimated as additional or alternative source of recharge. Detailed Hydro geological study has been carried out to explore subsurface profile by drilling the bore holes in different locations inside the study area. A confined aquifer was found at a level of 4m to 8m in decreasing levels. The soil stratum below the aquifer was found impervious. Hence boring of recharge shafts up to a depth of 4m to reach a confined aquifer layer will be the best suitable method for recharging the aquifer. The depth of aquifer is varying from 3m to 6m. Water fluctuation during monsoon and non-monsoon period was found to be around 5m. The estimated water demand is 1.6 MLD. Based on the Rational Formula, the runoff quantity is estimated as minimum of 13.48 MLD and maximum of 55.47 MLD. Thus the study identifies the significant quantity of runoff from the study area during the monsoon periods. The total estimated effluent available for recharge is estimated as 1.28 MLD. By considering the sources available, hydro geological conditions, the recharge pond and recharge shaft is designed. It encourages not only the maximum utilization of available natural resources but it helps in reducing the demand for freshwater and sustaining the vulnerable resources for future.Keywords

Reproductive and embryonic toxicity of hexavalent chromium (CrVI) is known, and adult testis is one of its vulnerable targets. However, it is not known if gestational and lactational exposure to excess Cr affects development and functions of Leydig cells during postnatal life. It is hypothesized that gestational/lactational exposure to CrVI may affect Leydig cell development and differentiation and its functions during postnatal life extending into adulthood. Pregnant [gestational days 9 to 21] and lactating [postnatal days (PND) 1 to 21] rats were exposed to 50ppm and 100ppm CrVI (K2Cr2O7) through drinking water, and testis was collected on PND 30, 60, 90 and 120, and subjected to light and transmission electron microscopic analysis. Serum testosterone and estradiol were determined adopting RIA. Histological evaluation of testes revealed hypertrophy and vacuolation of Leydig cells of CrVI-exposed rats; transmission electron micrographs (TEM) showed lipid accumulation, swollen mitochondria and disorganized smooth endoplasmic reticulum. Lactational exposure to CrVI led to decrease in the number of mitochondria and collapse of mitochondrial cristae. In general, the changes were obvious in PND 30 rats, and became less pronounced by PND 60 to become normal by PND 90. Serum testosterone and estradiol levels showed a general trend of opposite response to CrVI exposure. Gestational exposure to CrVI caused increase in testosterone level in prepuberal rats, but the trend was reversed by PND 60, and by PND 120 its level was more than in coeval controls. A similar trend was noticed in rats which had lactational exposure to CrVI but for a consistent increase in both steroids in PND 30 and PND 60 old rats which were exposed to 50ppm CrVI. By PND 90, testosterone remained elevated or normal, but by PND 120 its level was increased due to lactational exposure to CrVI. On the contrary, serum estradiol in these rats was low by PND 90 and became normal by PND 120. The findings partially support the hypothesis proposed and it is concluded that the fetal type Leydig cells are the major targets for the toxic effects of CrVI exposure during gestational and lactational periods where in lactational exposure may have a persistent effect leading to increased testosterone: estradiol ratio. Nevertheless, the effects of CrVI on testosterone and estradiol are reversible, as the adult type Leydig cells are unaffected.Keywords

Data sharing has never been easier with the advances of cloud computing. Data sharing with a large number of participants must take into account several issues, including efficiency, data integrity and privacy of data owner. A ring signature is a simplified group signature without any manager. It protects the anonymity of a signer. Unlike the group signature schemes the ring signature scheme requires neither a group manager, nor a setup procedure, nor the action of non-signing members. This signature does not reveal the identity of the signer but it may be varied with this signature that the signer belong to the possible signers set. There is no revocation manager. This allows unconditional anonymity of signer. Therefore, we introduce proxy signature scheme to allow a proxy signer to sign on behalf of an original signer. Using this scheme, we can achieve the singer ambiguity and key secrecy. To achieve user account security, we employee authentication process. In this authentication process user thump impression is capture and compared with the user data which are stored in database during registration process.Keywords

Mobile Ad hoc networks is a self-configuring infra structureless temporary network of mobile devices connected by wireless links. A major bottleneck in Mobile Ad hoc networks (MANETs) is the energy consumption since nodes are usually mobile and battery operated. This paper proposes an algorithm called Energy Efficient Delay Time Routing (EEDTR) which tries to increase the operational lifetime of Mobile Ad hoc networks. This algorithm is modified version of the existing Dynamic Source Routing (DSR) algorithm. This algorithm select fully distributed routes, thus balancing power consumption of the entire network and introduces a delay in forwarding the packets by nodes, which is inversely proportional to the remaining energy level of the node (EEDTR). The algorithm is designed and implemented using Global Mobile Simulator (GloMoSim), a scalable, simulation environment for network simulation. Based on the results obtained, it is concluded that the algorithm increases the lifetime of mobile ad hoc networks, at the expense of end delay and routing overhead.Keywords

There are different approaches of handover in multi carrier based broadband systems to provide QoS over mobile communication networks, in particularly for multicarrier systems like OFDM and MC-CDMA. This paper presents a handover technique referred to as semisoft handover which overcomes the drawbacks of previous handover techniques. Here, performance measurements are conducted to evaluate the proposed handover technique in terms of outage probability at the cell boundary by considering loading ratio and data rates.

Many Qualitative Bankruptcy Prediction models are available. These models use non-financial information as Qualitative factors and from which Bankruptcy is predicted. In the prior researches Genetic Algorithm was applied to generate Qualitative Bankruptcy Prediction Rules. However this Model uses only very less number of Qualitative factors and the generated rules has Repetitions and overlapping. To improve the Prediction accuracy we have proposed a model which applies more number of Qualitative factors and Prediction Rules are generated using Ant Colony Optimization Algorithm (ACO). The concept pheromone depositing and updating in Ant Colony Algorithm reduce the false negative rules in the bankruptcy prediction. The heuristic and probabilistic features of Ant Colony Algorithm increase the prediction accuracy of Bankruptcy.Keywords

Design of area and power-efficient high-speed data path logic systems are one of the most substantial areas of research in VLSI system design, The Carry Select Adder (CSLA) provides a good compromise between cost and performance in carry propagation adder design. However, conventional CSLA is still area-consuming due to the dual ripple carry adder (RCA) structure. In this paper, modification is done at gate-level to reduce area and power consumption. The Modified Carry Select-Adder (MCSLA) is designed for 8-bit, 16-bit, 32-bit and 64-bit and then compared with conventional CSLA respective architectures, this work evaluates the performance of the proposed designs in terms of delay, area, power, and their products by implementing in Xilinx fpga. This CSLA structures are implemented in booth multiplier in order to increase the efficiency of the booth multiplier.Keywords

Mobile Adhoc network is an instantaneous wireless network that is dynamic in nature. It supports single hop and multihop communication. In this infrastructure less network, clustering is a significant model to maintain the topology of the network. The clustering process includes different phases like cluster formation, cluster head selection, cluster maintenance. Choosing cluster head is important as the stability of the network depends on well-organized and resourceful cluster head. When the node has increased number of neighbors it can act as a link between the neighbor nodes which in further reduces the number of hops in multihop communication. Promisingly the node with more number of neighbors should also be available with enough energy to provide stability in the network. Hence these aspects demand the focus. In weight based cluster head selection, closeness and average minimum power required is considered for purging the ineligible nodes. The optimal set of nodes selected after purging will compete to become cluster head. The node with maximum weight selected as cluster head. Mathematical formulation is developed to show the proposed method provides optimum result. It is also suggested that weight factor in calculating the node weight should give precise importance to energy and node stability.Keywords

Duplex stainless steels find ever-increasing applications in chemical, off-shore, paper/pulp and fertilizer industries owing to their excellent combination of mechanical and corrosion properties [1-3]. More demanding situations prefer super duplex stainless steels, which have higher pitting resistance equivalence [4]. Even though many of the conventional welding processes are employed for joining of these high-performance materials, still the industries face the problem of achieving the desired properties - especially the corrosion resistance, in the resultant weldments [5-7]. Welding upsets the ferrite-austenite microstructural balance in the weld metal and in the high temperature heat affected zone. More so, industrially different gas/gas mixture combinations are employed for achieving the desired properties [8-10]. In the current work an attempt has been to study the effect of different welding processes on weld metal microstructure in the super duplex stainless steel grade SAF 2507.

Objectives: Molecular docking is widely used for molecular level recognition of leads and compounds which might be useful in the drug discovery domain. Docking is done in order to predict the binding mode and binding affinity of a complex which is formed by two or more constituent molecules with known structure. Objective is to find out the best available techniques in the docking domain. Methodology: We use Hex tool to simulate the various parameters and find out the bottlenecks. Fast Fourier Transform (FFT) and Spherical Polar Transformations (SPT) are applied to study the docking process. Findings: Various performance bottlenecks and parameter effect on the simulation. Improvements: It is observed that GPU optimization is possible by using FFT and SPT. The ligand space considered was limited to shape complementary. This could be considered for future e work.References

The present study aims to identify, characterize monitor and model the transport pathways of volcanic ashes and various features of the active phase of Barren Island volcano (BIV), Andaman and Nicobar Island, India during 2018 using the several Earth observation satellite technologies and field observations in the study area. Sentinel-2 satellite datasets have been used to identify volcanic eruption features such as lava flow, ash plume, cinder and vent and different directions of lava flow from the cinder cone during the 2018 eruptive phase of BIV. To visualize the major variations in thermal intensity and understand the behaviour of current volcanic activity, volcanic radiative power (VRP) and radiant fluxes of the recent eruptive phase were calculated using MIROVA. In addition, thermal anomaly was observed in the form of anomalous fire pixels for 44 days in FIRMS database. Also, NASA/NOAA Visible Infrared Imaging Radiometer Suite (VIIRS, VNP14IMGT) were used for validating the real-time activity of the 2018 volcanic eruption phase. The results obtained were closely related with the periods of high eruptions as observed in the Sentinel-2 datasets. The volcanic aerosol ‘sulphur dioxide’ (SO2) data (time series-area averaged) were analysed as well as a five-day forward trajectory and volcanic ash model for each eruption event was developed using HYSPLIT model to identify the transport pathways and extent of volcanic ash cloud in the lower atmosphere during the eruptive phase of the volcano.Keywords
