T. A. Janardhan Reddy, P. Srinivas Reddy
Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.210002

Engineers & technologists contribute significantly in our social development, economic progress, and enhancement of social and physical infrastructure. Industry in general and manufacturing in particular are facing unprecedented challenges due to globalization. Consequently, the business environment of manufacturing enterprises is facing increasing complexity. The engineering graduates and researchers with the ability to understand the technological complexities, the creative arts and skills are increasingly sought after by industrial and business world. Team-based activities are of great importance for students to learn and tackle and solve the complex global issues at later life. Self study and own initiatives of engineering students at learning stage enable and sharpen them to emerge out as highly acceptable engineers. The Washington Accord which emphasizes on outcome based learning is gaining increasing acceptance among many countries.

Arvind T,Srinivas NCH
Indian Journal of Dental Advancements , 2011,
Abstract: Digit sucking is a common childhood behaviour, which has an adaptive value for children up to the fourth year of life. It is usually associated with oral pleasure and self comforting behavior. Chronic practice may lead to dental and skeletal deformities. Reminder therapy using Bluegrass appliance has been proven successful to intercept digit sucking habit. We present here a case of a child aged 10 years with digit sucking habit intercepted by using a nonpunitive reminder therapy using Bluegrass appliance. This nonpunitive Bluegrass appliance proved to be very comfortable to the patient unlike other appliances and also it was successful in intercepting the habit within a short period of time.

B. Kalidasan,T. Srinivas
Journal of Renewable Energy , 2014, DOI: 10.1155/2014/757618
Abstract: Liquid flat plate collector (solar flat plate collector) is one of the important applications in solar thermal system. The development in solar photovoltaic is an emerging challenge for the solar thermal system. In the current work an attempt has been made to optimize the number of transparent covers and refractive index to improve the optical efficiency and thermal efficiency for the collector. Performance of the liquid flat plate collector at VIT University Vellore has been simulated numerically for January 21st at an interval of half an hour with different numbers of transparent covers (0–3) and different refractive index values ranging from 1.1 to 1.7. The formulation and solutions are developed with simple software Microsoft Office Excel to result the performance characteristics. The result shows that the efficiency of the flat plate collector increases with an increase in number of covers and decreases after an optimum number of covers. It also decreases with an increase in refractive index. The combination of optimum number (two) and lower refractive index (1.1) results improved useful heat. 1. Introduction The selection of number of transparent covers and refractive index of transparent cover, in a liquid flat plate collector, will affect the performance of the flat plate collector, thus it’s important in finding an optimum number of cover and an effective refractive index, for achieving higher efficiency irrespective of solar insulation and location. The flat plate collector is the heart of all solar energy thermal system designed for working at low temperature range of ambient to 60°C. The flat plate collector is basically a heat exchanger which transfers the radiant energy of the incident sunlight to the sensible heat of a working fluid—liquid or air. The solar liquid flat plate collector for water heating was invented by Saussure [1], a Swiss scientist, during 1767, as reported by Ackermann in the year 1915. However the use of flat plate collector became more popular in 1900s at United States and at California. During the past fifty years researchers and scientist from all over the world have done many contribution in this field, in building and testing different types of liquid flat plate collector. Among these works, the literature in number of transparent covers and has been reviewed on contributions in refractive index and transparent cover’s properties. Lampert [2] discussed in detail the properties of optical materials and coatings, which would predominantly increase the performance of the solar thermal system. He highlighted that for

Journal of Sustainable Bioenergy Systems (JSBS) , 2013, DOI: 10.4236/jsbs.2013.31009

Kenaf (Hibiscus cannabinus L.) is a warm-season annual. Kenaf fibers are commonly used for paper pulp and cordage, but it is also a promising lignocellulosic feedstock for bioenergy production, although optimum plant density for biomass production has not been determined for the northern region of the USA. The objective of this study was to determine the best plant density and row spacing of kenaf to maximize biomass yield and chemical composition for biofuel conversion. The experiments were conducted at Fargo and Prosper, ND, in 2010 and 2011. The experiment was a randomized complete block design with a split-plot arrangement where the main plot was tworowspacings (30 and60 cm) and the sub-plot fourplant densities (32, 16, 8, and 4 plants·m-2). Row spacing had a significant effect on both biomass and biofuel yield. Narrower rows had higher biomass and biofuel yield. Maximum biomass and estimated biofuel yield was obtained with the two highest plant densities of 16 and 32 plants·m-2 and fluctuated between 9.45 and 10.22 Mg·ha-1 and 1354 and1464 L·ha-1, respectively. Stem diameter increased with a decrease in plant density. Chemical composition varied with plant density; glucan (27%) and xylan (9.8%) content were lower at the lowest plant density. Ash content was not different among plant densities but it is interesting to mention the very low ash content of kenaf (0.15%). According to the results of this study, it is recommended to plant kenaf at 30-cm rows with a plant density of 16 to 32 plants·m-2 to maximize biomass yield. Kenaf has a tremendous potential as a cellulosic feedstock for biofuel and green chemicals in the Northern Great Plains because of high biomass yield and low ash content.

Thermodynamic properties of binary mixture for power generation systems
N. Shankar Ganesh,T. Srinivas
Journal of Engineering and Applied Sciences , 2010,
Abstract: In Kalina power generation as well as vapor absorption and refrigeration systems ammonia-water mixture has been used as working fluids. Unlike for pure components, binary mixtures additionally need mixture concentration to solve thermodynamic properties. A flowchart is developed to understand the computations of the properties. The thermodynamic properties for ammonia-water mixture have been generated using MATLAB computer code. The solved properties are bubble point temperature, dew point temperature, specific enthalpy, specific entropy, specific volume and exergy. The property charts i.e. enthalpy-concentration, entropy-concentration, temperature-concentration and exergy-concentration charts have been prepared. The present work can be used to simulate the power generating systems to get the feasibility of the proposed ideas up to 100 bar. This work can be used to carry out the exergy analysis of Kalina power cycles.
Processes assessment in binary mixture plant
N. Shankar Ganesh, T. Srinivas
International Journal of Energy and Environment , 2013,
Abstract: Binary fluid system has an efficient system of heat recovery compared to a single fluid system due to a better temperature match between hot and cold fluids. There are many applications with binary fluid system i.e. Kalina power generation, vapor absorption refrigeration, combined power and cooling etc. Due to involvement of three properties (pressure, temperature and concentration) in the processes evaluation, the solution is complicated compared to a pure substance. The current work simplifies this complex nature of solution and analyzes the basic processes to understand the processes behavior in power generation as well as cooling plants. Kalina power plant consists of regenerator, heat recovery vapor generator, condenser, mixture, separator, turbine, pump and throttling device. In addition to some of these components, the cooling plant consists of absorber which is similar in operation of condenser. The amount of vapor at the separator decreases with an increase in its pressure and temperature.

T. Raja Srinivas* and P. Veerabadhiran
Electronic Journal of Plant Breeding , 2010,
Abstract: A comparative study of the frequency and spectrum of chlorophyll mutations induced by gamma rays (150, 200, 250, 300 and350 Gy), sodium azide (0.5, 1.0, 1.5 and 2.0 mM) and combination treatments of gamma rays and sodium azide (100 Gy + 1.5mM, 150 Gy + 1.5 mM, 200 Gy + 1.0 mM, 250 Gy + 1.0 mM and 300 Gy + 0.5 mM) in M2 generationA was made in thelablab var. CO 9. Four different types of chlorophyll mutants viz., albina, viridis, chlorina and xantha were identified in thetreated population and mutation frequency was calculated on plant population basis. Frequency of chlorina mutants washighest followed by albina, xantha and viridis. Combination treatments in general proved to be very effective followed bysodium azide and gamma rays in inducing maximum frequency of chlorophyll mutations. Although the chlorophyll mutationsdo not have any economic value due to their lethal nature, such a study could be useful in identifying the threshold dose of amutagen that would increase the genetic variability and number of economically useful mutants in the segregating generations.
On the axioms of Leibniz algebroids associated to Nambu-Poisson manifolds
S. Srinivas Rau,T. Shreecharan
Mathematics , 2015,
Abstract: Let $E \rightarrow M$ be a smooth vector bundle with a bilinear product on $\Gamma(E)$ satisfying the Jacobi identity. Assuming only the existence of an anchor map $\mathfrak{a}$ we show that $\mathfrak{a}([X,Y]) = [\mathfrak{a}X,\mathfrak{a}Y]_c$. This gives the redundancy of the homomorphism condition in the definition of Leibniz algebroid; in particular if it arises from a Nambu-Poisson manifold.

Tamkang Journal of Mathematics , 2012, DOI: 10.5556/j.tkjm.43.2012.587-594
Abstract: In this paper, we introduced new subclasses $UCV_S(alpha,eta)$ and $SP_S(alpha,eta)$ which are sub classes of $UCV(alpha,eta)$ and $SP(alpha, eta)$ and studied the $T$ - $delta$ neighbourhoods of functions in these classes. The results obtained in this paper generalizes the recent results of Parvatham and Premabai[5], Ram Reddy and Thirupathi Reddy[6,7], Padmanabhan[4], and Ronning[8].
