  Full adder is the basic building blocks for various arithmetic circuits such as carry select adder, array multipliers, ripple carry adder, high speed adder, parallel adder and so on. In order to improve the performance of the digital computer systems one must improve the basic full adder cell. The proposed full adder design by using Gate Diffusion Input/Index (GDI) technique reduces the power consumption with less transistor count while maintaining less interconnection nodes of logic design, when compared with existing full adder designs such as complementary pass transistor logic, standard CMOS logic, transmission gate logic and transmission function adder logic. The simulation was carried out on TSMC HSPICE 180 nm technology. The simulation result shows that the design has more efficient with less area, less power consumption and as compared to existing hybrid full adder techniques.

  In real world problems, optimization techniques are useful for solving problems like, project schedules, assignment problems and network flow analysis. The main aspect of this study is to find the least transportation cost of some commodities through a capacitated network when the supply and demand of nodes and the capacity and cost of edges are represented as fuzzy numbers. Here, we are proposing a new algorithm for solving fuzzy transportation problem, where fuzzy demand and supply all are in the form of triangular fuzzy numbers. Where fuzzy demand and supply all are in the form of triangular fuzzy numbers. So, the proposed approach is very easy to understand and to apply on real life transportation problems for the decision makers.

  In large sensor network, data cannot be synced and needs multi hop routing to reach the destination from source. Selecting optimal routing path itself a big deal for present day sensor network. Most complex form of sensor network deployed in various farms such as military, DMZ regions, agricultural areas, etc. This make sensor networks to take advantage over multihop fashion with limited power backup and memory which in turn derives many security researchers towards WSN routing. In this study, we propose a novel routing protocol called "Route Max" for energy efficient routing in WSN. In order to achieve prolonged battery life and network lifetime, a hierarchical network tree structure is formed. The model is robust during cluster head selection by selecting limited power usage sensors along with sinks using hybrid form map model (combination of closed map and power law escape).

  A grievance means any discontent or dissatisfaction whether expressed or not by the employees in the organization. Grievance may be valid or not, arising out of anything connected with the company than an employee thinks, believes or even feels is unfair, unjust or inequitable. Grievances are natural in any organization. The problems of the employees should be solved as early as possible otherwise they can create serious problems for the organization, the industry and society.

  The aim of this study was to investigate the potent neuroprotective property of ethanol extract of Ocimum sanctum leaf (EEOS, Holy basil, Family: Labiataea) against excitotoxicity induced neurodegeneration by using Monosodium-L-glutamate (MSG) in Sprague-Dawley rats. The animals received EEOS (50, 100 and 200 mg kg-1) and memantine (MMT, 20 mg kg-1) daily for 7 days. On all the 7 days, MSG (2 g kg-1, i.p.) was administered one hour before drug treatment. The animals were evaluated for the neurobehavioral performance studies, body weight, food intake, diuretic activity, natriuretic and chloruretic effect immediately after MSG administration from day 1 to day 7. On the day 7, the rats were sacrificed and the brain was removed for histopathological examination. Significant differences in behavioural performance between the control and MSG-treated rats were also found in all paradigms studied. Treatment with EEOS reversed the water-excretory-diuretic effect of MSG and caused a significant dose dependent enhancement in the volume of urine output. An interesting observation made during the study was an increased excretion of Na+ and Cl¯ ions and reduced excretion of K+, in the urine samples of EEOS-treated rats. Therefore, it may be concluded that the decrease in body weight and hypophagia, along with enhanced water intake and diuresis observed in MSG-treated rats were found to be attenuated by treatment with EEOS. Histopathological evaluation showed that treatment with EEOS and MMT significantly protected the neurodegeneration of the CA1 neuronal cells.

  Seaweeds have been used by mankind as medicine and food for more than 13,000 years. Marine algae are considered to produce a valuable phytoconstituents characterized by a broad spectrum of antitumor activities. The aim of the present study was to explore the effect of different solvent extracts of Sargassum wightii, Greville against Dalton’s Ascitic Lymphoma (DAL) in Swiss male albino mice. DAL cells were injected intraperitoneally 1x106 cell to the mice. Two days after cells injection the animals were treated with different solvent extracts of Sargassum wightii at dose of 200 mg kg-1 for 14 days. 5-fluorouracil (20 mg kg-1) was used as reference drug. On day 11, cancer cell number, packed cell volume, decrease in tumour weight of the mice, increase in life span and hematological parameters were evaluated and compared with the same parameters in control. A significant increase in the life span and a decrease in the cancer cell number and tumour weight were noted in the tumour-induced mice after treatment with the extract. The haematological parameters were also normalized by the ethanolic and chloroform extracts in tumour-induced mice. These observations are suggestive of the protective effect of ethanolic extract of Sargassum wightii is comparatively better than other two tested extracts against Dalton’s Ascitic Lymphoma (DAL).
