Steel fiber reinforced concrete under cyclic loading: An overview
In recent years, it has been recognized that addition of small closely spaced and uniform dispersed discrete steel fibers in concrete substantially improve its static and dynamic properties. The addition of steel fibers from 0.5 to 2.0 percent by volume in concrete is found to impart superior strength characteristics i.e. compressive strength, flexural strength, shear strength, fatigue strength and impact resistance. Recently, the use of steel fibers has increased in flexural members and columns of concrete structures subjected to cyclic loadings such as bridge decks, highway roads, runways of airports, offshore platforms and buildings. It is necessary to obtain more information on the mechanical behaviour of steel fiber reinforced concrete under cyclic loading in attempting applications of SFRC in structural members. The present investigation was planned to study the plain and steel fiber reinforced concrete under cyclic loading. The basic parameters of the study were fiber contents expressed as volume fraction and stress levels expressed as a percentage of the maximum flexural strength. The fiber contents used were 0.5 and 1.0% by volume of concrete. The beams were tested at three stress levels i.e. 85%, 90%, and 95%. Straight mild steel fibers were used in the study with an aspect ratio of 70. The physical properties of the basic constituent material viz, cement, sand, coarse aggregate, steel fiber were obtained as per relevant Indian standard specification. The compressive strength of concrete was obtained at 28 days. The mix proportion used was 1: 1.52:1.88 by weight with a water-cement ratio of 0.47. In fresh state properties of SFRC, workability tests present were carried out with indicators of workability i.e, slump, compaction factor and inverted cone test. From the study, it was found that the addition of fibers to the concrete effects the cyclic loading life significantly under flexural cyclic loading. The variability in the cyclic loading life of specimen is quite large as expected in any cyclic loading test programme. The ultimate failure followed almost immediately after the first crack.

Improvement in production rate by reducing the defects of injection moulding by DMAIC approach
Six Sigma is a well-structured methodology that concentrates on decreasing variation, measuring defects and beneficent the quality of products, processes, and services. Six Sigma methodologies were primarily progressing by Motorola in the 1980s and it targeted a difficult aim of 3.4 parts per million defects. Six Sigma has been on an unbelievable run over 25 years, manufacture important savings to the under the most line of many large and small organizations. This work presents the step-by-step application of the Six Sigma (acquaint, Measure, Analysis, progress, and monitoring) approach to eliminate the defects in injection moulding process this has helped to decrease defects in the process and thereby progress productivity.

Multiple view video delivery system
The Entertainment industry is acquired by the 3D technology after 2D, but now the one which gives more depth perception and the capability to view freely is the Multiview. Most of the improvements in video compression are based on the introduction of H.264/MPEG-4.H.264/MPEG-4 is the video coding standard from which multiple reference pictures are taken as the compression method. End-user expects to have free viewing points; this system overcomes the lack of free view and provides a high degree of freedom to the user to have a good experience. The system uses the broadcast and broadband network to deliver the videos. To deliver high volume multimedia adaptive Peer to peer network and the DVB (digital video broadcast network) are used. This system provides genuine 3D effect without glasses. It even helps to perform pixel-level editing.

Evaluation of antioxidant activity of stem and flower extracts of Ageratum conyzoides
The study aimed to evaluate and compare antioxidant activity couple with the phytochemical screening of different extracts from stems and flowers of Ageratum conyzoides. N-hexane, ethyl acetate, and ethanolic extracts were subjected to different phytochemical screening and antioxidant activity. The flavonoids and phenolic contents were determined using spectrophotometry method. The three extracts showed evidence for the presence of secondary metabolites such as flavonoids, steroids, terpenoids, and glycosides. Saponins were only present in ethanol extract. Phenol was present in both ethanol, ethyl acetate, and n-hexane extracts. The concentration of flavonoids ranges from 145.33 ± 0.665 to 711.00 ± 2.024 µg/g expressed as Quercetin equivalents. Total phenolic content expressed as Gallic acid equivalents range from 19.26 ± 0.305 to 150.33 ± 1.020 µg/g of extract. The DPPH inhibition was also determined using spectrophotometry method and it was observed between 34.65 to 84.90%. The results obtained in this study show that the stems and flowers of Ageratum conyzoides are rich in flavonoids and phenols. Thus, the plant possesses scavenging property.

Determinants of an entrepreneurial performance of coir yarn spinners in Tamil Nadu- An analysis
An empirical analysis was made to estimate the determinants of entrepreneurial performance of coir yarn spinners operating in one of the Coir cluster regions promoted by the Government of Tamil Nadu. Demographic, social, economic, personality, work experience and competency on coir spinning profile of the coir yarn spinners and the enterprise profile such as size and geographical location of the spinning units were considered as predictor variables effecting for entrepreneurial managerial performance. The study found that there were differences and variations in the entrepreneurial managerial performance among coir yarn spinners. Such differences and variations in the performance are contributed by personal, personality, social, economic and competency variables of the coir yarn spinners and also by the size and geographical location of the enterprise. However, the study finds that the most important determinants of entrepreneurial performance are concerned with the competency level and the personality of the entrepreneur. High competency particularly on machine capacity utilization, management-oriented style coupled with high level of contact with change agents are the most important determinants of the entrepreneurial managerial high performance of the coir yarn spinners.
