Abstract

Antigen sharing amongst gastro-intestinal nematodes viz., Haemonchus contortus, Oesophagostomum columbianum and Bunostomum trigonocephalum was evaluated by inhibition ELISA. Two antigens namely soluble extract antigen (SEA) and gut integral membrane antigen (GIMA) were prepared and hyper immune sera were raised in rabbits against SEA of three referral nematodes. Based on inhibition ELISA, it was observed that the SEA of H. contortus had 36.4 and 28.87% cross-reactivity with inhibited sera of B. trigonocephalum and O. columbianum respectively whereas, the GIMA showed 29.2 and 25.1% crossreactivity with B. trignocephalum and O. columbianum. The SEA of O. columbianum exhibited 34.3 and 22.0% and the GIMA revealed 27.3 and 22.8% cross-reactivity with B. trigonocephalum and H. contortus respectively. The SEA of B. trigonocephalum showed 24.8 and 34.2% and the GIMA exhibited 21.48 and 30.25% crossreactivity with O. columbianum and H. contortus respectively. Further, it was concluded that H. contortus showed a high degree of antigen sharing with B. trigonocephalum than O. columbianum.

Abstract

In this paper, we present a new approach for concealing secret message in a digital image by adding three layer securities. In the first layer, the secret image is encrypted by using the famed AES algorithm. In the second layer, we establish a Non-Uniform Block Adaptive Segmentation on Image (NUBASI) algorithm for generating segments of the cover image. This algorithm accept a Key from sender and by using this key, split the cover image into small pieces each with different dimension. In the third layer, a new randomized secret sharing algorithm hide the secret data into the different segments. This algorithm defines 32 different patterns for selecting the segments order to implant the cipher data. This proposed method was implemented and tested for various size cover images and secret messages. The quality of the final stego-image and original image are compared and analyzed through their PSNR values.

Abstract

Experiments were on a shoe-brush-shaped fin consisting of a single bunch of splayed metal wires of circular cross-section from copper base plate. The fin was fabricated and its heat transfer characteristics were studied through experiments and numerical simulation. Fabrication was done through sand casting and the product was machined for required dimensions and surface finish. Numerical studies were done using ANSYS Fluent 3D. It can be inferred from the experiments and numerical studies that the fabricated fin maintains a lower base plate temperature than the rectangular flat fin and cylindrical pin fin for the same heat transfer rate, material and exposed area.

The study has the following limitations, some of the respondents might have answered in biased manner, the Study was limited and confined to Chidambaram Taluk only and time was a major constraint due to which the sample size is limited. Findings: The study reveals that there is a significant difference observed between income generation, contribution to house hold income, participation in house hold financial decision, improvement in standard of living, change in social status, awareness about social issues, involvement in social issues at locality, improvement in basic house hold facilities and amenities, ability to solve family related problems, self-confidence, attainment of knowledge and skills, decision making capability and ability to tackle family problems before and after microfinance usage and participation in Self Help Group. Hence, the study concludes that women are empowered because of the usage of microfinance and participation in Self Help Group. Novelty/Improvement: In every economy, women play an integral part. For achieving all round development and harmonious growth, women should also be given equal rights. In order to achieve economic development, importance has to be given to the women labor. Nowadays SHG are voluntary organizations, through which members are given micro credits and it ease them to become entrepreneurs. The empowerment of women in rural as well as urban areas can be achieved through formation of Self Help Groups (SHG) of women. The economic empowerment, which is dependent on the overall empowerment of women, can be achieved through these SHGs which involve women in the areas like health, sanitation, nutrition, agriculture, forestry etc., apart from involving them in activities pertaining micro credit.

Abstract

Employee engagement is a high impact factor towards productivity of an organization. It is an emotional and psychological attachment of an employee towards his/her organization. An engaged employee is always more reliable, self-motivated and loyal to strengthen the organization towards sustainable position. There are many factors that influence an employee engagement in association with demographic factors. Here the researchers have taken individual factor upon grouping up various variables and tried to find the relationship between the demographic factors and the individual factors. Objectives: The purpose of this study is to find out the contributing variables which are significantly influencing in the engaged workforce and to study the effect and relationship among the EE factors in association with output factors. Method/Analysis: The researchers have selected 124 respondents and collected primary data by adopting standard questionnaire. The statistical tools such as Chi square test, one-way ANOVA and regression analysis were used to analyze the data. Findings: The predictor variables viz., Co-Workers, Department, Rewards and recognition, Opportunities, Team work and Immediate Supervisor are statistically significant factors towards employee engagement. The regression results also show that the variables such as Job, Superior, Organization and Communication are not statistically significant. There is a significant relationship between employee engagement and outcomes - discretionary efforts and retention. There is a statistical significant effect of employee engagement on Discretionary Effort which is one of the outcomes of the study. Applications/Improvements: The present study suggests the important factors contribute the employee engagement in a better way in banks. The study results will make certain impact oriented changes in banks.

Abstract

During Machining enormous amount of coolant is applied at the cutting zone, the basic functionalities of the coolant being cooling, lubricating and flushing of chips. Generally the cutting fluids are of mineral base oils with additives such as Sulphur, Phosphorous and Chlorine. These fluids along with the swarf result in a mist during operation, which is extremely harmful when inhaled and also a serious hazard when exposed to skin resulting in disorders. The use of such cutting fluids poses a potential hazard to the work personnel and the working environment. After usage of these coolants proper care is to be taken during disposal. The presence of aromatic hydrocarbons causes environmental pollution.

Abstract

Solar energy that contains bright heat and light from the sun is often controlled using modern technology such as photovoltaic, solar heating, artificial photosynthesis, solar architecture and solar thermal electricity. This study concerned with an experimental analysis of solar parabolic trough collector. The sunlight is reflected from the parabolic trough surface and focused on the evacuated absorber tube. The trough is usually aligned to the N–S axis and can be rotated normally according to the sun position from east to west. We have studied the potential of a solar thermal system for hot-water generation. The parabolic trough concentrator was made of galvanized sheet metal on which solar reflective films were pasted. The heat transfer fluid, viz. water runs through the absorber tube and absorbs concentrated heat energy. It has been designed with principal focus 0.1 m from the vertex so that the receiver heat loss is minimized. Data were collected on water inlet temperature, outlet temperature of the heat transfer fluid, solar radiation and water flow rate (days) during March to May 2019 at Coimbatore, Tamil Nadu, India. Also, the processing parameters were optimized because they are the key factors affecting the performance of the solar collector. Grey relational analysis was used to solve the optimization. Through confirmatory experiments, the input variables such as time, angle of tracking and solar radiation, as well as output variables such as inlet temperature, outlet temperature and efficiency were obtained, and the optimal conditions were verified. A suitable choice of input parameters such as tracking angle of 120° provides a high efficiency rate at 2 pm for March, April and May
