Abstract

Objective: To study antifertility activity of various extracts of A. odoratissimus Roxb. and C. guianensis Aubl. Materials and methods: Antifertility activity of benzene, ethanol and water extracts of leaves of A. odoratissimus and bark and flowers of C. guianensis was studied for their effect on duration of various stages of oestrus cycle in adult female rats and on the number implantation sites in the pregnant rats. Results: All the extracts of A. odoratissimus leaf and ethanol and water extracts of C. guianensis bark and flower showed significant prolongation of dioestrus stage (p<0.05). Ethanol and water extracts of A. odoratissimus leaf showed anti-implantation effect. Ethanol extract of C. guianensis bark and all the extracts of its flower reduced the number of implantations. Conclusion: The disturbances in the reproductive cycle indicate effect of these plants on the sex hormones in the animals. Prevention of implantation may be due their interference in the receptive stage of the uteri and endometrial sensitivity for decidualisation. The results suggest that the both plants are having antifertility activity and possible therapeutic use.

Abstract

Objective: To study antidiabetic activity of two novel androstane derivatives (JB1 and JB2) isolated from the ethanolic extract of seeds of Syzygium cuminii Linn. Materials and methods: Compounds JB1 and JB2 were isolated from ethanolic extract of seeds of S. cuminii by normal phase column chromatography using toluene: ethyl acetate (80:20) as mobile phase and their structure was elucidated by spectroscopic methods. Antidiabetic activity of JB1 and JB2 and the ethanolic extract was evaluated using alloxan as diabetogenic agent. The potency of JB1 and JB2 (100 mg/kg) and the ethanolic extract (200 mg/kg), was compared with glibenclamide (5 mg/kg). The elevated blood glucose levels were monitored colorimetrically using glucose oxidase enzyme system. Results: Compound JB1 was found to be 3, 15-dihydroxy Δ³ androstene [16, 17-C] (6' methyl, 2'- 1, 3-dihydroxy-1-propene) 4H pyran whereas JB2 to be 3-hydroxy androstane [16, 17-C] (6' methyl, 2'-1-hydroxy-isopropene-1-yl) 4, 5, 6 H pyran. Ethanolic extract of seeds of S. cuminii reduced elevated blood glucose levels in alloxan-induced diabetes in rats on single dose as well as prolonged treatment. Compound JB1 was found to be more effective than JB2 as it showed peak activity at the end of day three, which was comparable to ethanolic extract.

Abstract

Mobile node is a collection of mobile nodes which forms a temporary network. Some of the nodes in an ad hoc network may want access to an external network, such as internet. Different mechanisms have been proposed to integrate MANETs and the Internet[10][11]. These mechanisms are differing based on gateway discovery mechanism, and Adhoc routing protocol[13][16]. When MANET is connected to the Internet, it is important for the mobile nodes to detect an available gateway providing an access to the Internet. The objective of this paper is based on Mobile Ad-hoc Network (MANET) routing protocols used in gateways. AODV[1] is one of the most popular routing protocols for ad-hoc networks; it uses the flooding technique for locating the destinations, and gateway, possibly cause an overhead in the network. To overcome this problem we have introduced the MPR (Multi Point Relay) algorithm [2][9] in the AODV protocol in order to reduce the number of messages broadcasted during the flooding phase and also the MPRAODV protocol uses the hybrid approach to find out the gateway[14][15]. The extended AODV (MPRAODV) using MPR reduces the overhead and enhances the packet delivery performance.

Abstract

Peer-to-peer (P2P) systems have rapidly grown in popularity and have become a dominant means for sharing resources in the past few years. Since the nodes are often heterogeneous in these types of systems a load balancing key was a challenging. While several load-balancing schemes have been proposed in the literature, these solutions are typically ad hoc, heuristic based, and localized. In this project, we present a general framework, HiGLOB, for global load balancing in structured P2P systems. Each node in HiGLOB has two key components: 1) a histogram manager maintains a histogram that reflects a global view of the distribution of the load in the system, and 2) a load-balancing manager that redistributes the load whenever the node becomes overloaded or underloaded. A P2P network is partitioned into non overlapping regions corresponding to histogram bucked by exploiting the routing metadata. A mechanism was proposed to keep the cost of constructing and maintaining the histograms low. This scheme can control and bound the amount of load imbalance across the system. Skip Graph, BATON, and Chord are the three existing structured P2P system where we demonstrate the effectiveness of HIGLOB by instantiating. Experimental results clearly indicate that our approach works well.

Abstract

Since research trends can change dynamically,researchers have to keep up with these new trends and undertake new research topics. Therefore, research communities for new research domains are important. Domain-specific search engines (or vertical search engines) alleviate the problem to some extent, by allowing researchers to perform searches in a particular domain and providing customized community researchers. In this paper, we propose a method to discover research communities. The key features of our method are a network model of papers and a word assignment technique for the communities obtained. This research work is focused on evaluating a bibliometrics search engine called Domain Expert, which produces list of community researchers e-mail addresses of cyber domain experts available freely in the Web. This exploits techniques such as bibliometrics and community mining using Brush structure, which is a new data structure model for indexing by community formation.

Abstract

In this paper, the probabilistic neural network (PNN) is proposed as the classifier to discriminate between the magnetizing inrush and the phase to phase fault of a power transformer. The probabilistic neural network (PNN), is investigated for the protection of power transformer. Current waveforms due to different types of events, such as phase to phase faults and circuit breaker switching were generated using power transformer simulated in MATLAB simulation software. Simulated data were used to train the classifiers. To evaluate the developed algorithm for various operating condition of the transformer, including internal faults, are obtained by modeling the transformer in MATLAB Simulink. The data from the simulation are trained and tested by using Probabilistic Neural Network for discrimination of magnetic inrush and phase to phase fault.

Abstract

The problem of m-machine permutation flowshop scheduling is considered in this paper. The objective is to minimize the makespan. The flowshop scheduling problem is a typical combinatorial optimization problem and has been proved to be strongly NP-hard. Hence, several heuristics and meta-heuristics were addressed by the researchers. In this paper, a discrete African wild dog algorithm is applied for solving the flowshop scheduling problems. Computational results using benchmark problems show that the proposed algorithm outperforms many other algorithms addressed in the literature.

Abstract

Background: Breast cancer is one of the most prevalent cancers among women in world. Unfortunately, even after adequate treatment, some patients experience severe pain either due to disease progression or due to treatment related side effects. Aim: The purpose of this study was to describe the impact of five interventions on the quality of life (QOL) and the role of FACT-B Questionnaire in this way to health care professionals achieve a deeper understanding of QOL. Methods: The data for the research were collected by FACT-B scale one week and four months after breast cancer treatment with chemotherapy. In this Pilot study of 20 breast cancer patients took part in the intervention of Aerobic, Acupressue, Guided Imagery, Amla supplementation and Spiritual counselling.QOL was assessed using FACT-B Scale. Results: The results show that the patients with breast cancer receiving chemotherapy benefitted from the practised interventions during and after the treatment. In prior to enforce the QOL model, the breast cancer patients had poor quality of life. The effectiveness of the intervention was evaluated by post test scores. The mean score had improved from 48.05-99.07 with paired tvalve of 19.59 (P<0.05) after implementation of multi intervention package. The finding shows that there was a highly significant association found between pre and post scores. The Chi-Square test result shows that there is no significant association between patients with breast cancer receiving chemotherapy with demographic variables. Further research is required to determine the effectiveness of multi intervention package with large samples and to identify their underlying mechanism.

Abstract

Improving the efficiency of dynamic routing problem on road network is a difficult .There is numerous works proposed for this problem and they try to solve this in different aspects. Most of the existing routing problem based on static approach. In this paper, we propose a fuzzy Dijkstra’s shortest path algorithm based on dynamic approach. The linguistic variables that qualify user parameters are quantified using fuzzy set theory that provides fuzzy numbers outputs to predict the shortest route on network. By handling the fuzzy parameter, it gives issue to compare the distance between two different paths with their edge lengths represented by fuzzy numbers. The addition of fuzzy numbers using graded mean integration representation is used to improve Dijkstra’s algorithm. A numerical example of a road network is used to illustrate the efficiency of the proposed method.

Abstract

This paper focusing on the usage of biomaterials as self-curing agents in concrete. Biomaterials like Calatropis Gigantea (CG) and Spinacea Oleracia (SO) are found to be equivalent to the existing chemical admixture Polyethylene Glycol since they have specific characteristic of holding water and releasing whenever it is needed as internal reservoirs like self-curing agents and their microstructural properties are resembling Polyethylene Glycol. From the previous studies, it was found that these biomaterials of a small quantity of about less than 1% by weight of cement performing better than PEG and found to be cost effective and no need of water curing of the day one of concreting and achieving the required strength 9-13. This paper discusses on the strength development of self-cured concrete using above said biomaterials at the age of 3, 7, 14, 21, 28 and 56 days without water curing and compared with the performance of conventional water cured concrete specimen. Also splitting tensile strength and flexural strength of both concrete at 28 days were determined and compared. From the results, it is found that Spinacea Oleracia is performing better than CG and PEG.
