EFFECT OF CHROMIUM ON GROWTH AND YIELD OF Vigna mungo (L.)

This study was conducted to find out the effect of different concentrations (control 5, 10, 25, 50, 100 and 200 mg/l) of chromium on growth, yield of black gram (Vigna mungo L.). Pot culture experiments were carried out with black gram seeds with different concentrations of chromium solution. The morphological growth parameters were recorded at 15, 30, 45 and 60 days old chromium treated plants. The yield was recorded at the time of harvest. The study revealed that, the increase in chromium reduce the growth and and yield in black gram plants

Biodiversity of Medicinal Plants in Thudaripettai Village, Nagapattinam District, Tamil Nadu, India

The medicinal plants have received more attention among researchers to treat various diseases and disorders. This study was aimed to record the various medicinal plants present in Thudaripettai Village situated in Tharangambadi Taluk, Nagapattinam district of Tamil Nadu. A total of 60 plant species belonging to 35 families were reported with their medicinal values. These results will provide information about medicinal plants and methods of utilization of these plants to cure various diseases of mankind. Survey of the information of medicinal plants used by the villagers were collected and arranged alphabetically followed by common name, vernacular name, family name, parts of use, methods of uses, medicinal uses and their habit. The information is very much useful for further research which will lead to the discovery of new bioactive compounds from the above medicinal plants

3-(2-Meth­oxy­naphthalen-1-yl)-2-benzofuran-1(3H)-one

The asymmetric unit of the title compound, C19H14O3, contains two crystallographically independent mol­ecules in which the dihedral angles between the naphthalene and benzofuran ring systems are 76.49 (7) and 86.17 (7)°. In the crystal, mol­ecules are linked by inter­molecular C—H⋯O hydrogen-bonding inter­actions into chains running parallel to the a axis. In addition, the crystal packing is stabilized by C—H⋯π inter­actions

Modified Design Hardware and Wireless Sensors Networks for Designing Future Combat System

Future combat system (FCS) is a network, which connects eighteen individual weapon scheme connected with the soldier all the way through the network.Supporting the soldier with real time situational awareness and cooperative operability among forces to entire a mission successfully with low mortality rate is the fundamental thought, there by enabling the soldier to see first, understand first and take action decisively. Since, most of the system operates in remote environment with battery support, power consumption is a serious issue. System with many nodal points has to be encrypted strictly to prevent the network from attacks (simply hacking). In this paper, an analysis was made on use of instruments with less power consumption, particularly custom design hardware and wireless sensors or sensors to tackle this difficulty

An Enhanced Distributed Clustering Methodology and Data Aggregation in Connecting Dissimilar Wireless Sensor Networks

One of the major advantages of wireless sensor network is their ability to operate in unattended, harsh environments in which existing human-in-the-loop monitoring schemes are uncertain, inefficient and sometimes impossible. Therefore, wireless sensors are expected to be deployed randomly in thepredetermined area of interest by a relatively uncontrolled manner. Given the huge area to be covered, the short lifespan of the battery-operated wireless sensors and the possibility of having damaged sensor nodes during deployment, large population of sensors are expected in the majority of wireless sensor applications. In centralized clustering, the cluster head isfixed. The rest of the nodes in the cluster act as member nodes. In distributed clustering, the cluster head is not fixed. The cluster head keeps onshiftingformnodetonodewithintheclusteronthebasisofsomeparameters.Hybridclusteringisthecombinationofbothcentralizedclusteringanddistributed clustering mechanisms. This paper gives a brief overview on clustering process in wireless sensor networks and an enhanced distributed clustering methodology and data aggregation in connecting dissimilar wireless sensor Networks. The proposed method is compared with LEACH and HEED Clustering methods

Distribution of Wireless Sensor Network for Efficient Environmental Monitoring and Greenhouse Control

Nowadays, the applications of these networks are copious, varied and the applications in agriculture are still budding. One interesting purpose is in environmental monitoring and greenhouse control, where the crop conditions such as weather and soil do not depend on natural agents. To control and observe the environmental factors, sensors and actuators are necessary. Under these conditions, these devices must be used to make a distributed measure, scattering sensors all over the greenhouse using distributed clustering mechanism. This paper reveals an initiative of environmental monitoring and greenhouse control using a sensor network

(4-Methyl­phen­yl)[2-(thio­phen-2-ylcarbon­yl)phen­yl]methanone

The crystal studied of the title compound, C19H14O2S, was an inversion twin with a 0.7 (1):0.3 (1) domain ratio. The central benzene ring makes dihedral angles of 63.31 (9) and 60.86 (9)°, respectively, with the 4-methyl­phenyl and thio­phene rings. In the crystal, mol­ecules are linked by weak inter­molecular C—H⋯O hydrogen bonds and S⋯π [3.609 (3) Å] inter­actions

Occurrence of Oratosquilla oratoria (De Haan, 1844) and Oratosquillina gravieri (Manning, 1978) from the trawl bycatches of Nagapattinam region, Tamil Nadu

Six species of mantis shrimps were recorded in the trawl catches of Nagapattinam region during January – December, 2018. The occurrence of two species namely Oratosquilla oratoria (De Haan, 1844) and Oratosquillina gravieri (Manning, 1978) were reported for the first time in the trawl bycatches of Nagapattinam region. The morphometrics of these two species is reported in this paper. Presence of inferodistal spine in the merus of the raptorial claw, rostral plate short and trapezoid to square in shape, 5th abdominal segment without submedian patch, 4th abdominal segment submedian carinae unarmed in Oratosquilla oratoria and rostral plate elongate and rectangle, lateral process of 6th thoracic somite with slender, triangular anterior lobe and dactylus of the raptorial claw with 6 teeth in Oratosquillina gravieri are chief characters to differentiate from other species
