E-Learning has become a major field of interest in recent year, and multiple approaches and solutions have been developed. Testing in E-Iearning software is the most important way of assuring the quality of the application. The E-Learning software contains miscommunication or no communication, software complexity, programming errors, time pressures and changing requirements, there are too many unrealistic software which results in bugs. In order to remove or defuse the bugs that cause a lot of project failures at the final stage of the delivery., this paper focuses on adducing a Reliable code coverage technique in software testing, which will ensure a bug free delivery of the software development. Software testing aims at detecting error-prone areas. This helps in the detection and correction of errors. It can be applied at the unit of integration and system levels of the software testing process, and it is usually done at the unit level. This method of test design uncovered many errors or problems. Experimental results show that, the increase in software performance rating and software quality assurance increases the testing level in performance. © 2013 IEEE. Source

The flowers of Pongamia pinnata was extracted with methanol was subjected to preliminary phytochemical analysis. Flavonoids, alkaloids, carbohydrates, tannins, lignins, saponins, glycosides and fixed oil and fats were found to be present. The methanolic crude extract further fractionated with three different solvents, i.e. benzene, dethyl ether and ethyl acetate.and the chemical composition of the ethyl acetate extract was determined by GC/MS analysis.The present investigation revealed the following major compounds from P.pinnata. In this analysis 30 bioactive phytochemical constituents were identified. Based on the peak area and molecular weight, the dibutyl phthalate and oleic acid was observed as the major constituents.

Classification of medical imagery is a difficult and challenging process due to the intricacy of the images and lack of models of the anatomy that totally captures the probable distortions in each structure. Cervical cancer is one of the major causes of death among other types of the cancers in women worldwide. Proper and timely diagnosis can prevent the life to some level. Consequently we have proposed an automated trustworthy system for the diagnosis of the cervical cancer using texture features and machine learning algorithm in Pap smear images, it is very beneficial to prevent cancer, also increases the reliability of the diagnosis. Proposed system is a multi-stage system for cell nucleus extraction and cancer diagnosis. First, noise removal is performed in the preprocessing step on the Pap smear images. Texture features are extracted from these noise free Pap smear images. Next phase of the proposed system is classification that is based on these extracted features, RBF and kernel based SVM classification is used. More than 94% accuracy is achieved by the classification phase, proved that the proposed algorithm accuracy is good at detecting the cancer in the Pap smear images. © 2006-2016 Asian Research Publishing Network (ARPN).

In present study, the methanol method for carotenoids extraction from the feathers waste of Galius gallus (chicken) was introduced. The antimicrobial activity of the carotenoids extract against Escherichia coli, Aspergillus niger, Aspergillus flavus, Saccharomyces cerevisiae and Bacillus subtilis was also elucidated. Results showed that the optimum extraction conditions was at a temperature of 50°C, a solvent-solid ratio of 10:1 and duration of 30 min. The disc diffusion method and minimum inhibitory concentration(MIC) determination showed that the extract has a wide spectrum of antimicrobial activity against E. coli, B. subtilis and S. cerevisiae with their inhibition zones ranging from 8.90 mm to 15.45 mm and the MIC ranging from 16.75 μg/mL to 90 μg/mL. However, it showed no inhibition effect on A. niger and A. flavus. Copyright © EM International. Source

Endophytic bacteriareside with in plant hosts without causing disease. In our study, we isolates four endophytic bacteria from explants (root,stem, petiole, and leaf) of Aloe Barbadensis, Adhatoda vasica, Phyllanthus amarus and Calotrophis gigantea.Entophytic bacteria such as Azotobacter,Xanthomonas and Pseudomonas could be identified from explants through various biochemical test. Endophytic bacteria were beneficial to the plant growth and it can be proved that inoculate to Mustard plant which was showed good growth promoting effect. The endophytes contributes substances that possess biocontrol activity against Curvularia sp., and Alternaria sp.,.Thus in our study,we focus on the growth promoting effect of endophytic bacteria in mustard plant and biocontrol activity against fungal pathogens.
